AB Two serine residues within the first 17 amino acid residues of huntingtin (N17) are crucial for modulation of mutant huntingtin toxicity in cell and mouse genetic models of Huntington's disease. Here we show that the stress-dependent phosphorylation of huntingtin at Ser13 and Ser16 affects N17 conformation and targets full-length huntingtin to chromatin-dependent sub-regions of the nucleus, the mitotic spindle and cleavage furrow during cell division. Polyglutamine-expanded mutant huntingtin is hypophosphorylated in N17 in both homozygous and heterozygous cell contexts. By high-content screening in live cells, we identified kinase inhibitors that modulated N17 phosphorylation and hence huntingtin subcellular localization. N17 phosphorylation was reduced by casein kinase-2 inhibitors. Paradoxically, IKK beta kinase inhibition increased N17 phosphorylation, affecting huntingtin nuclear and subnuclear localization. These data indicate that huntingtin phosphorylation at Ser13 and Ser16 can be modulated by small-molecule drugs, which may have therapeutic potential in Huntington's disease.

AB Progressive supranuclear palsy (PSP) is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP (cases) and 3,247 controls (stage 1) followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the stage 1 SNPs that yielded P <= 10(-3). We found significant previously unidentified signals (P < 5 x 10(-8)) associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component.

AB Cells that are deficient in homologous recombination, such as those that lack functional breast cancer-associated 1 (BRCA1) or BRCA2, are hypersensitive to inhibition of poly(ADP-ribose) polymerase (PARP). However, BRCA-deficient tumors represent only a small fraction of adult cancers, which might restrict the therapeutic utility of PARP inhibitor monotherapy. Cyclindependent kinase 1 (Cdk1) phosphorylates BRCA1, and this is essential for efficient formation of BRCA1 foci. Here we show that depletion or inhibition of Cdk1 compromises the ability of cells to repair DNA by homologous recombination. Combined inhibition of Cdk1 and PARP in BRCA-wild-type cancer cells resulted in reduced colony formation, delayed growth of human tumor xenografts and tumor regression with prolonged survival in a mouse model of lung adenocarcinoma. Inhibition of Cdk1 did not sensitize nontransformed cells or tissues to inhibition of PARP. Because reduced Cdk1 activity impaired BRCA1 function and consequently, repair by homologous recombination, inhibition of Cdk1 represents a plausible strategy for expanding the utility of PARP inhibitors to BRCA-proficient cancers.

AB Since their invention some 50 years ago(1), lasers have made a tremendous impact on modern science and technology. Nevertheless, lasing has so far relied on artificial or engineered optical gain materials, such as doped crystals, semiconductors, synthetic dyes and purified gases(2,3). Here, we show that fluorescent proteins(4,5) in cells are a viable gain medium for optical amplification, and report the first successful realization of biological cell lasers based on green fluorescent protein (GFP). We demonstrate in vitro protein lasers using recombinant GFP solutions and introduce a laser based on single live cells expressing GFP. On optical pumping with nanojoule/nanosecond pulses, individual cells in a high-Q microcavity produce bright, directional and narrowband laser emission, with characteristic longitudinal and transverse modes. Lasing cells remained alive even after prolonged lasing action. Light amplification and lasing from and within biological systems pave the way to new forms of intracellular sensing, cytometry and imaging.

AB SWI/SNF chromatin remodelling complexes use the energy of ATP hydrolysis to remodel nucleosomes and to modulate transcription. Growing evidence indicates that these complexes have a widespread role in tumour suppression, as inactivating mutations in several SWI/SNF subunits have recently been identified at a high frequency in a variety of cancers. However, the mechanisms by which mutations in these complexes drive tumorigenesis are unclear. In this Review we discuss the contributions of SWI/SNF mutations to cancer formation, examine their normal functions and discuss opportunities for novel therapeutic interventions for SWI/SNF-mutant cancers.

AB After decades of stagnation, recent therapeutic advances in melanoma seem on the horizon. The discovery of the genetic underpinnings of this historically refractory disease has exposed potential targets for therapy, BRAF mutations being principal among them. In the 8 years following the discovery of BRAF mutations in 50-60% of advanced melanomas, only recently have potent and selective inhibitors of this intracellular signaling molecule shown efficacy from early clinical testing. Vemurafenib (PLX4032) and GSK2118436, two orally available and well tolerated agents are on the verge of transforming the landscape of melanoma therapy based on the promising results of their respective phase I, II, and III trials.

DE Monte Carlo; proton imaging; multiple coulomb scattering
AB The accuracy of proton therapy is partially limited by uncertainties that result from changing pathological conditions in the patient such as tumor motion and shrinkage. These uncertainties can be minimized with the help of a time-resolved range telescope. Monte Carlo methods can help improve the performance of range telescopes by tracking proton interactions on a particle-by-particle basis thus broadening our understanding on the behavior of protons within the patient and the detector. This paper compared the proton multiple coulomb scattering algorithms in the Monte Carlo codes MCNPX and Geant4 to well-established scattering theories. We focus only on beam energies associated with proton imaging. Despite slight discrepancies between scattering algorithms, both codes appear to be capable of providing useful particle-tracking information for applications such as the proton range telescope.

AB Proton radiography imaging qualities have been studied using Monte Carlo simulations. A specific phantom, made of different common tissues, was implemented for simulations using the Massachusetts General Hospital treatment proton beam, pure 230- and 490-MeV proton beams, and a pure 100-keV X-ray beam. Along with spatial resolution, the signal-to-noise ratio and the contrast-to-noise ratio were specified and compared for each tissue type and geometry, using filtered radiographs taking into account only primary proton interactions, both primary and secondary proton interactions, and both contributions while performing angular and energetic cuts. This work particularly highlights the faculty for proton radiography to image both low- and high-density tissues. This could play an important role in diagnosing specific tumor types, such as lung cancer, for which conventional radiography operates poorly.

DE proton radiography; proton therapy; Monte Carlo
AB Proton radiography is an imaging technique with potential application in proton radiation therapy. The ability of a proton radiograph to differentiate anatomical features in the thoracic region, such as heart, lung, rib cage, shoulder, etc., was qualitatively investigated using Monte Carlo simulations. A patient with a stage IIIA non-small cell lung cancer tumor located in the right upper lobe and mediastinum was considered for this study. The GEANT4 Monte Carlo toolkit was used to simulate proton transport through a proton nozzle and through the lung area of the patient, registering in a phase-space file the entry and exit energy, position, and motion direction of each proton. The Monte Carlo simulation ran a total of 10 million histories with the highest deliverable energy of 235 MeV at the Francis H. Burr Proton Therapy Center. The proton radiograph was then generated independently of the Monte Carlo simulation, using a numerical algorithm to input the proton position, direction of motion, and energy kept in the entry and exit phase-space files. The proton radiograph was compared to the standard portal X-ray image for tissue and tumor contrast, and for visibility relative to the background lung tissue. The preliminary results with GEANT4 showed that the proton radiography can produce images with good spatial resolution and excellent soft tissue contrast, resulting in better tumor edge localization within a soft tissue background region such as the lung.

DE proton radiography; Monte Carlo; range telescope
AB The superior dose conformation from protons is attributed to the Bragg peak near the end of the proton range. One challenge in proton cancer treatment is to assess the proton range fluctuations due to organ motion such as respiration. A time-resolved proton range telescope that measures coordinates, direction cosines, and the residual range of each proton can be useful in detecting and quantifying variations in radiological path length during the course of proton radiotherapy. In this paper, the Monte Carlo N-Particle eXtended (MCNPX) code was used to simulate the range telescope and study the image quality. To validate the MCNPX simulations, a simulated proton radiograph was compared with an experimentally acquired film for the same phantom. In addition, four quality assurance phantoms were simulated to investigate the quality of simulated proton radiography. Finally, the methods were applied to one phase of a patient four-dimensional computed tomography (4DCT) data set for proton radiography simulations. The results indicate that Monte Carlo simulations offer data that are useful in analyzing image spatial and temporal resolutions. Simulations show that it is useful to quantify the tumor position changes due to respiration by using a proton telescope.

SO NUCLEIC ACIDS RESEARCH

DT Article
ID SPECTRAL LIBRARY; COMPOUND IDENTIFICATION; METABOLITES; SEARCH
AB Gas chromatography-mass spectrometry (GC-MS) acquisitions routinely yield hundreds to thousands of Electron Ionization (EI) mass spectra. The chemical identification of these spectra typically involves a search protocol that seeks an exact match to a reference spectrum. Reference spectra are found in comprehensive libraries of small molecule EI spectra curated by commercial and public entities. We developed ARISTO (Automatic Reduction of Ion Spectra To Ontology), a webtool, which provides information regarding the general chemical nature of the compound underlying an input EI mass spectrum. Importantly, ARISTO can provide such annotation without necessitating an exact match to a specific compound. ARISTO provides assignments to a subset of the ChEBI (Chemical Entities of Biological Interest) dictionary, an ontology, which aims to cover biologically relevant small molecules. Our system takes as input a mass spectrum represented as a series of mass and intensity pairs; the system returns a graphical representation of the supported ontology as well as a detailed table of suggested annotations along with their associated statistical evidence. ARISTO is accessible at this URL: http://www.ionspectra.org/aristo.

AB Insulin resistance has been associated with the accumulation of fat within skeletal muscle fibers as intramyocellular lipid (IMCL). Here, we have examined in a cross-sectional study the interrelationships among IMCL, insulin sensitivity, and adiposity in European Americans (EAs) and African Americans (AAs). In 43 EA and 43 AA subjects, we measured soleus IMCL content with proton-magnetic resonance spectroscopy, insulin sensitivity with hyperinsulinemic-euglycemic clamp, and body composition with dual-energy X-ray absorptiometry. The AA and EA subgroups had similar IMCL content, insulin sensitivity, and percent fat, but only in EA was IMCL correlated with insulin sensitivity (r = -0.47, P < 0.01), BMI (r = 0.56, P < 0.01), percent fat (r = 0.35, P < 0.05), trunk fat (r = 0.47, P < 0.01), leg fat (r = 0.40, P < 0.05), and waist and hip circumferences (r = 0.54 and 0.55, respectively, P < 0.01). In a multiple regression model including IMCL, race, and a race by IMCL interaction, the interaction was found to be a significant predictor (t = 1.69, DF = 1, P = 0.0422). IMCL is related to insulin sensitivity and adiposity in EA but not in AA, suggesting that IMCL may not function as a pathophysiological factor in individuals of African descent. These results highlight ethnic differences in the determinants of insulin sensitivity and in the pathogenesis of the metabolic syndrome trait cluster.

AB Background: Patients undergoing gastric bypass lose substantial weight, but 20% regain weight starting at 2 years after surgery. Our objective was to identify behavioral predictors of weight regain after laparoscopic Roux-en-Y gastric bypass (LRYGB).
Methods: We retrospectively surveyed 197 patients for factors predictive of weight regain (>= 15% from lowest weight to weight at survey completion). Consecutive patients who had bariatric surgery from 1/2003 through 12/2008 were identified from an existing database. Response rate was 76%, with 150 patients completing the survey.
Results: Follow-up after LRYGB was 45.0+/-12.7 months, 22% of patients had weight regain. After controlling for age, gender, and follow-up time, factors associated with weight regain included low physical activity (odds ratio (OR) 6.92, P=0.010), low self-esteem (OR 6.86, P=0.008), and Eating Inventory Disinhibition (OR 1.30, P=0.029).
Conclusions: Physical activity, self-esteem, and maladaptive eating may be associated with weight regain after LRYGB. These factors should be addressed in prospective studies of weight loss following bariatric surgery, as they may identify patients at risk for weight regain who may benefit from tailored interventions.

ID OBSTETRIC SIMULATION
AB Faculty involvement in simulation training is essential for curriculum development, utilization of their clinical expertise in teaching, and ultimately for validating the importance of the training program. Several barriers to faculty involvement exist, including competing demands on time, the challenges in developing curriculum, and teaching using simulation. Through our experiences in implementing a widely expansive program, we have identified several areas to encourage and engage faculty. Further discussion as a medical education community is needed to support the interaction and involvement of our faculty to support and promote ongoing simulation education.

AB << LEAP > highlights the findings and application of Cochrane reviews and other evidence pertinent to the practice of physical therapy. The Cochrane Library is a respected source of reliable evidence related to health care. Cochrane systematic reviews explore the evidence for and against the effectiveness and appropriateness of interventions-medications, surgery, education, nutrition, exercise-and the evidence for and against the use of diagnostic tests for specific conditions. Cochrane reviews are designed to facilitate the decisions of clinicians, patients, and others in health care by providing a careful review and interpretation of research studies published in the scientific literature.(1) Each article in this PTJ series summarizes a Cochrane review or other scientific evidence on a single topic and presents clinical scenarios based on real patients or programs to illustrate how the results of the review can be used to directly inform clinical decisions. This article focuses on an older patient with intermittent claudication. Could a supervised exercise program increase the distance he is able to walk before stopping because of pain?

AB Objective: To assess the knowledge and the use of antimicrobial stewardship resources, such as hospital antibiograms and infectious disease consultants, by spinal cord injury or disorder (SCI/D) providers.
Design and Setting: Anonymous Internet-based, cross-sectional survey.
Participants: A total of 314 SCI/D physicians, nurse practitioners, and physician assistants who prescribe antibiotics were invited to complete a survey.
Main Outcome Measurements: Knowledge of and behaviors related to antibiograms and infectious disease (ID) consults.
Results: A total of 118 providers (80 physicians, 20 nurse practitioners, 18 physician assistants) completed the survey (37.6% response rate). Approximately one-third of respondents indicated that they did not have access to (11.0%) or were unsure of (28.0%) the existence of facility antibiograms. Half of the providers indicated that they never used antibiograms to determine treatment for their SCI/D patients. Respondent factors associated with viewing facility antibiograms were older age, employment at SCI/D specialty centers, a longer duration since completion of training, and years of SCI/D patient care. Nearly all respondents (95%) indicated that they believed that improving access to antibiotic prescribing data or antibiograms would reduce antibiotic resistance. More than one-third reported that they never or seldom used ID consults.
Conclusions: A significant portion of SCI/D providers who prescribe antibiotics do not have access to facility antibiograms or are unaware of their existence and thus could not use them for determining antibiotic treatment. Interventions could include formal education of providers on how to access antibiograms and the use of ID physicians as a resource, as well as providing technologic support, such as electronic facility-level antibiograms as part of the medical record system, which can be easily identified if a provider is making a decision on an antibiotic.

AB Hyperglycemia is a defining characteristic of type 2 diabetes mellitus and is a major risk factor associated with the development of many microvascular complications. There are numerous therapies currently available to treat hyperglycemia, but glycemic control rates remain poor. One potential reason is the decline in beta-cell function over time, which decreases the effectiveness of therapies that rely on insulin action. The kidney occupies a central position in the control of glucose homeostasis by its role in gluconeogenesis and by regulating glucose excretion. Under normal conditions, glucose filtered by the kidney is virtually totally reabsorbed in the proximal tubule by the sodium-glucose co-transporter 2 (SGLT2). Inhibition of SGLT2 is an attractive, insulin-independent target for increasing glucose excretion in the setting of hyperglycemia. A number of SGLT2 inhibitors have been synthesized, and results from preclinical studies have shown that they increase glucose excretion and normalize plasma glucose in diabetic models. Initial clinical data are promising and suggest that SGLT2 inhibitors may be a new therapeutic option for treating type 2 diabetes mellitus.

AB Progesterone withdrawal has been proposed as an underlying factor in premenstrual syndrome and postpartum depression. Progesterone withdrawal induces forced swim test (FST) immobility in mice, a depression-like behavior, but the contribution of specific receptors to this effect is unclear. The role of progesterone's GABA(A) receptor-modulating metabolite allopregnanolone in depression- and anxiety-related behaviors has been extensively documented, but little attention has been paid to the role of progesterone receptors. We administered the classic progesterone receptor antagonist mifepristone (RU-38486) and the specific progesterone receptor antagonist CDB-4124 to mice that had been primed with progesterone for five days, and found that both compounds induced FST immobility reliably, robustly, and in a dose-dependent fashion. Although CDB-4124 increased FST immobility, it did not suppress initial activity in a locomotor test. These findings suggest that decreased progesterone receptor activity contributes to depression-like behavior in mice, consistent with the hypothesis that progesterone withdrawal may contribute to the symptoms of premenstrual syndrome or postpartum depression.

AB Objective The rate-corrected electrocardiographic QT (QTc) interval may significantly increase in patients with schizophrenia taking antipsychotics. The objective of this naturalistic study was to assess the prevalence of prolonged QTc interval in a large population of inpatients with chronic schizophrenia and to explore QTc relationship with demographic variables and prescribed treatments.
Materials and methods Electrocardiograms were obtained from age-and sex-matched 456 controls and 1,006 inpatients with schizophrenia (male/female= 689/317) taking antipsychotics. QTc prolongation was defined as a mean value of two standard deviations above the controls. The adjusted relative risk was calculated using logistic regression analysis.
Results QTc prolongation was present in 45 (4.5%) of 1,006 patients overall. Fewer men (3.2%, 22 of 689) than women (7.3%, 23 of 317) displayed QTc prolongation (p<0.004). Moreover, QTc intervals were shorter in male (391 +/- 31 ms) than female subjects (400 +/- 37 ms) (p<0.001). Clozapine was found to produce a longer QTc intervals compared to risperidone and typical antipsychotics. Furthermore, multiple regression analysis showed that significant predictors for QTc prolongation were comorbid cardiovascular disease, antipsychotic types, sex, and age (all p<0.01).
Conclusion Our present findings suggest that there are sex differences in the prevalence of QTc prolongation and QTc lengthening in schizophrenia. Antipsychotic types are risk factors for QTc prolongation, and risks are substantially higher for clozapine.

AB The default mode network (DMN), one of several resting-state networks (RSN) in the brain, is thought to be involved in self-referential thought, awareness, and episodic memories. Nicotine improves cognitive performance, in part by improving attention. Nicotinic agonists have been shown to decrease activity in regions within DMN and increase activity in regions involved in visual attention during effortful processing of external stimuli. It is unknown if these pharmacological effects also occur in the absence of effortful processing.
This study aims to determine if nicotine suppresses activity in default mode and enhances activity in extra-striate RSNs in the absence of an external visual task.
Within-subject, single-blinded, counterbalanced study of 19 non-smoking subjects who had resting functional MRI scans after 7 mg nicotine or placebo patch. Group independent component analysis was performed. The DMN component was identified by spatial correlation with a reference DMN mask. A visual attention component was identified by spatial correlation with an extra-striate mask. Analyses were conducted using statistical parametric mapping.
Nicotine was associated with decreased activity in regions within the DMN and increased activity in extra-striate regions.
Suppression of DMN and enhancement of extra-striate resting-state activity in the absence of visual stimuli or effortful processing suggest that nicotine's cognitive effects may involve a shift in activity from networks that process internal to those that process external information. This is a potential mechanism by which cholinergic agonists may have a beneficial effect in diseases associated with altered resting-state activity.

Materials and Methods: For this retrospective HIPAA-compliant study, institutional review board approval was obtained and the requirement for informed consent was waived. Restrictive GBCA guidelines were adopted in May 2007. The guidelines (a) require a recent serum creatinine level measurement in any patient who is aged 60 years or older and/or at risk for renal disease, (b) limit the maximal weight-based GBCA dose administered to any patient with an estimated glomerular filtration rate (eGFR) lower than 60 mL/min/m(2) to 20 mL, and (c) prohibit the administration of any GBCA in patients who have an eGFR lower than 30 mL/min/m(2) and/or are undergoing chronic dialysis treatment (except in emergency situations). The electronic medical records were searched for all contrast material-enhanced magnetic resonance (MR) imaging examinations performed during the post-guidelines adoption period between January 2008 and March 2010 and the pre-guidelines adoption and transitional period between January 2002 and December 2007. Separate pathology records were searched for biopsy-confirmed cases of NSF during the same study periods. The incidences of NSF during the pre-guidelines adoption and transitional period and post-guidelines adoption period were compared by using the paired Z test.
Results: A total of 52 954 contrast-enhanced MR examinations were performed during the post-guidelines adoption period. Of these 52 954 examinations, 46 464 (88%) were performed in adult patients with an eGFR of 60 mL/min/m(2) or higher or presumed normal renal function and 6454 (12%) were performed in patients with an eGFR of 3059 mL/min/m(2). Thirty-six patients with an eGFR lower than 30 mL/min/m(2) underwent contrast-enhanced MR imaging for emergent indications. Review of the pathology records for January 2008 to September 2010 revealed no new cases of NSF resulting from GBCA exposure.
Conclusion: After restrictive guidelines regarding GBCA administration were instituted, no new cases of NSF were identified among 52 954 contrast-enhanced MR examinations, including those performed in patients with an eGFR lower than 60 mL/min/m(2). (C) RSNA, 2011

REPLICATION; JUNCTIONS; PROTEIN; GENOME; CELLS
AB DNA interstrand cross-links (ICLs) are toxic DNA lesions whose repair in S phase of eukaryotic cells is incompletely understood. In Xenopus egg extracts, ICL repair is initiated when two replication forks converge on the lesion. Dual incisions then create a DNA double-strand break (DSB) in one sister chromatid, whereas lesion bypass restores the other sister. We report that the broken sister chromatid is repaired via RAD51-dependent strand invasion into the regenerated sister. Recombination acts downstream of FANCI-FANCD2, yet RAD51 binds ICL-stalled replication forks independently of FANCI-FANCD2 and before DSB formation. Our results elucidate the functional link between the Fanconi anemia pathway and the recombination machinery during ICL repair. In addition, they demonstrate the complete repair of a DSB via homologous recombination in vitro.

AB Glaucoma drainage devices are being used with increasing frequency for patients. Sterile endophthalmitis after implantation has been reported. Unlike traditional trabeculectomy surgery, the persistence of an implant may be contributory. As glaucoma specialists consider emerging technologies in implantable glaucoma drainage devices, it is important to understand that sterile endophthalmitis may be associated with these devices.

AB We recently reported that cerebral and cardiac injuries are mitigated in immature female piglets after severe hemorrhage with subsequent cardiac arrest. Female sex was also associated with a smaller increase in the cerebral expression of inducible nitric oxide synthase (iNOS) and neuronal nitric oxide synthase (nNOS). In the current study, we tested the hypothesis that exogenously administered 17 beta-estradiol (E-2) can improve neurological outcome by NOS modulation. Thirty-nine sexually immature piglets were bled to a mean arterial pressure of 35 mmHg over 15 min. Fifty micrograms per kilogram of E-2 was then administered to 10 male and 10 female animals (estradiol group), whereas control animals (n = 10 males and 9 females) received equal volume of normal saline. The animals were then subjected to ventricular fibrillation (4 min) followed by up to 15 min of open-chest cardiopulmonary resuscitation. Vasopressin 0.4 U . kg(-1) and amiodarone 0.5 mg . kg(-1) were given, and 3 mL . kg(-1) of 7.5% saline with 6% dextran was administered over 20 min. All surviving animals were killed after 3 h, and their brains examined for histological injury and NOS expression. No significant differences were observed in survival or hemodynamics between the groups. Compared with the control group, animals in the E-2 group exhibited a significantly smaller increase in nNOS and iNOS expression, a smaller blood-brain-barrier disruption, and a mitigated neuronal injury. There was a significant correlation between nNOS and iNOS levels and neuronal injury. Interestingly, estradiol attenuated cerebral damage (including lower activation of nNOS and iNOS) both in male and female piglets. In conclusion, in our immature piglet model of hypovolemic cardiac arrest, E-2 downregulates iNOS and nNOS expression and results in decreased blood-brain-barrier permeability disruption and smaller neuronal injury.

AB Background and Purpose-Admission infarct core lesion size is an important determinant of management and outcome in acute (<9 hours) stroke. Our purposes were to: (1) determine the optimal CT perfusion parameter to define infarct core using various postprocessing platforms; and (2) establish the degree of variability in threshold values between these different platforms.
Methods-We evaluated 48 consecutive cases with vessel occlusion and admission CT perfusion and diffusion-weighted imaging within 3 hours of each other. CT perfusion was acquired with a "second-generation" 66-second biphasic cine protocol and postprocessed using "standard" (from 2 vendors, "A-std" and "B-std") and "delay-corrected" (from 1 vendor, "A-dc") commercial software. Receiver operating characteristic curve analysis was performed comparing each CT perfusion parameter-both absolute and normalized to the contralateral uninvolved hemisphere-between infarcted and noninfarcted regions as defined by coregistered diffusion-weighted imaging.
Results-Cerebral blood flow had the highest accuracy (receiver operating characteristic area under the curve) for all 3 platforms (P<0.01). The maximal areas under the curve for each parameter were: absolute cerebral blood flow 0.88, cerebral blood volume 0.81, and mean transit time 0.82 and relative Cerebral blood flow 0.88, cerebral blood volume 0.83, and mean transit time 0.82. Optimal receiver operating characteristic operating point thresholds varied significantly between different platforms (Friedman test, P<0.01).
Conclusions-Admission absolute and normalized "second-generation" cine acquired CT cerebral blood flow lesion volumes correlate more closely with diffusion-weighted imaging-defined infarct core than do those of CT cerebral blood volume or mean transit time. Although limited availability of diffusion-weighted imaging for some patients creates impetus to develop alternative methods of estimating core, the marked variability in quantification among different postprocessing software limits generalizability of parameter map thresholds between platforms.

AB Background and Purpose-Framingham calculators are typically implemented in 1-on-1 settings to determine if a patient is at high risk for development of cardiovascular disease in the next 10 years. Because health care administrative datasets are including more clinical information, we explored how well administrative data-derived Framingham scores could identify persons who would have stroke develop in the next year.
Methods-Using a nested case-control design, we compared all 313 persons who had a first-time stroke at 5 Veterans Administration Medical Centers with a random sample of 25 361 persons who did not have a first-time stroke in 2008. We compared Framingham scores and risk using administrative data available at the end of 2007.
Results-Stroke patients had higher risk profile than controls: older age, higher systolic blood pressure and total cholesterol, more likely to have diabetes, cardiovascular disease, left ventricular hypertrophy, and more likely to use treatment for blood pressure (P<0.05). The mean Framingham generalized cardiovascular disease score (18.0 versus 14.5) as well as the mean Framingham stroke-specific score (13.2 versus 10.2) was higher for stroke cases than controls (both P<0.0001). The c-statistic for the generalized cardiovascular disease score was 0.68 (95% CI, 0.65-0.70) and for the stroke score was 0.64 (95% CI, 0.62-0.67).
Conclusions-Persons who had a stroke develop in the next year had a worse Framingham risk profile, as determined by administrative data. Future studies should examine how to improve the stroke predictive tools and to identify the appropriate populations and uses for applying stroke risk predictive tools. (Stroke. 2011; 42: 1982-1987.)

AB Background. Postoperative abdominal adhesions are a major cause of morbidity and mortality. We previously demonstrated the inhibitory effect of sunitinib, a receptor tyrosine kinase inhibitor; on adhesion formation in a murine model, and now investigate its effects in a rabbit model.
Methods. Forty New Zealand White rabbits underwent a standard adhesion procedure. Preoperatively, animals were randomized to treatment with sunitinib or saline (control). Animals were treated with a total of 11 daily doses, 1 preoperative and 10 postoperative. One group of 20 animals (group 1) was humanely killed on postoperative day 10, and the other (group 2) on postoperative day 30. After killing, adhesions were scored and abdominal wounds were collected for tensile strength and microvessel density measurements.
Results. Sunitinib-treated animals in group 1 had a mean tenacity score of 1.67 +/- 0.29 compared with 3.60 +/- 0.16 in control animals (P < .01). Similarly, the mean tenacity scores for sunitinib-treated and control animals in group 2 were 0.20 +/- 0.20 and 2.70 +/- 0.37 respectively (P < .01). The mean uterine involvement scores for sunitinib-treated and control animals in group 1 were 1.44 +/- 0.29 and 3.70 +/- 0.15, respectively (P < .01), and in group 2 were 0.10 +/- 0.10 and 2.70 +/- 0.45, respectively (P < .01). There were no differences in ultimate or modular wound tensile strength between sunitinib-treated and control animals.
Conclusion. Sunitinib significantly reduces postoperative adhesions in a rabbit model. This therapy may improve postoperative adhesion-related morbidity and mortality. (Surgery 2011;150:32-8.)

AB Background: Paragangliomas in the region of the thyroid gland are rare tumors that can present a diagnostic challenge by mimicking follicular and c-cell derived thyroid tumors.
Summary: Thyroid-associated paragangliomas are likely a subset of laryngeal paragangliomas and, although quite rare, should be considered in the differential diagnosis of a hypervascular thyroid nodule. The preoperative diagnosis of thyroid-associated paragangliomas can be challenging since the cytologic and histologic features overlap with more common primary thyroid neoplasms, in particular medullary carcinoma. Differential expression of a panel of immunohistochemical markers, including neuro-specific enolase, chromogranin A, synaptophysin, keratin, and S100, can be used to distinguish thyroid-associated paragangliomas from primary thyroid tumors. Intraoperatively, thyroid-associated paragangliomas may be associated with significant intraoperative bleeding and are often densely adherent to surrounding tissues, including the recurrent laryngeal nerve. Interestingly, the aggressive local behavior of these tumors does not correspond to potential formalignancy, as there are no patients with malignant thyroid-associated paragangliomas reported in the medical literature. Therefore, these tumors may be treated with limited resection. Postoperatively, patients with paragangliomas should receive hormonal evaluation for functional disease, imaging evaluation for multicentric and metastatic disease, and genetic counseling.
Conclusion: Thyroid-associated paragangliomas are an important part of the differential diagnosis of a hypervascular thyroid nodule, especially in a patient with a fine-needle aspiration biopsy suggestive of medullary thyroid carcinoma, but with unremarkable serum calcitonin levels. Consideration of a thyroid-associated paraganglioma also has important operative and postoperative implications for determining the extent of thyroid resection as well as follow-up testing.

AB Currently available bioreactor systems used by tissue engineers permit either direct, high-magnification observation of cell behavior or application of mechanical loads to growing tissue constructs, but not both simultaneously. Further, in most loading bioreactors, the volume of the dead space is not minimized to reduce the cost associated with perfusion media, exogenous stimulatory/inhibitory agents, proteases, and label. We have designed, developed, and tested a bioreactor that simultaneously satisfies the combined requirements of providing (i) controlled tensile mechanical stimulation, (ii) direct high-magnification imaging capability, and (iii) low dead-space volume. This novel mechanostimulatory (uniaxial tensile loading) bioreactor operates on an inverted microscope and permits continuous optical access (up to 600 X) to a loaded, growing construct for extended periods of time (weeks). The reactor employs an adjustable reaction chamber in which the dead space can be reduced to <2 mL. The device has been used to cultivate our human primary corneal fibroblast-derived, tissue-engineered system for up to 14 days. Using the instrument we have successfully recorded (i) the process of fibroblasts populating, growing to confluence, and stratifying on different substrates; (ii) recorded complex and organized cell sheet motions; and (iii) recorded the behavior of a subpopulation of what appear to be degradative/catabolic cells within our fibroblast culture. The device is capable of providing detailed, long-term, dynamic images of mechanically stimulated cell/matrix interaction that have not been observed previously.

TI Pretreatment metabotype as a predictor of response to sertraline or

DT Article
DE major depressive disorder; metabolomics; sertraline; placebo
AB The purpose of this study was to determine whether the baseline metabolic profile (that is, metabotype) of a patient with major depressive disorder (MDD) would define how an individual will respond to treatment. Outpatients with MDD were randomly assigned to sertraline (up to 150 mg per day) (N = 43) or placebo (N = 46) in a double-blind 4-week trial. Baseline serum samples were profiled using the liquid chromatography electrochemical array; the output was digitized to create a 'digital map' of the entire measurable response for a particular sample. Response was defined as >= 50% reduction baseline to week 4 in the 17-item Hamilton Rating Scale for Depression total score. Models were built using the one-out method for cross-validation. Multivariate analyses showed that metabolic profiles partially separated responders and non-responders to sertraline or to placebo. For the sertraline models, the overall correct classification rate was 81% whereas it was 72% for the placebo models. Several pathways were implicated in separation of responders and non-responders on sertraline and on placebo including phenylalanine, tryptophan, purine and tocopherol. Dihydroxyphenylacetic acid, tocopherols and serotonin were common metabolites in separating responders and non-responders to both drug and placebo. Pretreatment metabotypes may predict which depressed patients will respond to acute treatment (4 weeks) with sertraline or placebo. Some pathways were informative for both treatments whereas other pathways were unique in predicting response to either sertraline or placebo. Metabolomics may inform the biochemical basis for the early efficacy of sertraline.

AB OBJECTIVE To evaluate contemporary national practice pattern trends in the use of thermal ablation (radiofrequency ablation and cryoablation) in the management of stage I renal cell carcinoma (RCC), and the factors that lead to using thermal ablation (TA) vs partial (PN) or radical nephrectomy (RN) in the United States.
METHODS Within the Surveillance, Epidemiology and End Results (SEER) database, we identified subjects with T1-N0M0 RCC treated with either PN, RN, or TA between 2004 and 2007. Proportions, trends, and multivariable logistic regression models tested the predictors of the use of TA.
RESULTS In total, 15,145 patients underwent a procedure for an RCC that was organ-confined and <= 7 cm. Of these, 578 underwent TA, 4402 underwent PN, and 10,165 underwent RN. On unadjusted analyses, patients who received TA were more likely to be older, single, have smaller tumor size, be diagnosed in more recent years, and have more unspecified histologic subtype and tumor grade. In multivariable adjusted analyses, single status (P = .02), male gender (P = .01), increasing age (P < .01), year of diagnosis (P < .01), and smaller tumor size (P = .01) were strong independent predictors of TA use compared with surgery (PN or RN). Further adjusted analyses showed no statistical difference in cancer-specific or overall survival between TA vs PN or RN.
CONCLUSIONS TA use for stage I RCC increased over a relatively short period and was performed more commonly in patients of older age and with smaller tumor size. Longer follow-up is needed to assess the comparative effectiveness of TA vs surgery. UROLOGY 78: 93-98, 2011. (C) 2011 Elsevier Inc.

AB OBJECTIVES To define the role of positive surgical margins (PSMs) after radical retropubic prostatectomy as a predictor of biochemical failure (BCF) in prostate cancer with respect to pathologic stage.
METHODS A retrospective cohort study of 300 patients who had undergone radical retropubic prostatectomy from 1993 to 1995 was performed. The role of margin status and the length of the PSM in the progression to BCF was defined after controlling for the preoperative prostate-specific antigen level, Gleason score, tumor stage, tumor volume, seminal vesical invasion, lymphovascular invasion, and perineural invasion using a multivariate regression model. The median follow-up time was 12 years.
RESULTS The presence of PSMs correlated with a shorter time to BCF in men with Stage pT2 disease (P < .0001) but not in men with Stage pT3 disease (P = .66). Of the patients with Stage pT2 disease and PSMs, the PSM length did not correlate with progression to BCF. PSMs predicted a shorter time to progression to BCF in patients with high-and low-volume pT2 disease (P = .0261 and P = .0003, respectively). Only PSMs predicted a shorter time to BCF on multivariate analysis in patients with Stage pT2 cancer (hazard ratio 2.33, 95% confidence interval 1.495-3.723). In patients with Stage pT3 disease, PSMs were not associated with an increased risk of BCF (hazard ratio 0.747, 95% confidence interval 0.328-1.703).
CONCLUSIONS Surgical margin status did not affect the risk of BCF in patients with Stage pT3a disease; however, it did affect patients with Stage pT2 disease, irrespective of PSM length or disease volume. During 12 years of follow-up, the patients with PSMs and Stage pT2 disease had a risk of BCF similar to that of the patients with Stage pT3 disease. UROLOGY 78: 121-125, 2011. (C) 2011 Elsevier Inc.

ID GUILLAIN-BARRE-SYNDROME; PHRENIC-NERVE; RESPIRATORY-FAILURE;
POLYRADICULONEUROPATHY; CIDP
AB Background -
Ventilatory involvement is rarely reported in chronic inflammatory demyelinating polyneuropathy (CIDP), but small prospective studies showed frequent involvement of phrenic nerves, which is usually overshadowed by severe limb weakness.
Objectives -
To report the clinical features of CIDP associated with ventilatory failure.
Results -
There were seven patients (43% women), with a mean age of 58.6 (range 38-82). The clinical courses were relapsing in five and progressive in two. Four patients had an initial event simulating Guillain-Barre syndrome (GBS). Ventilatory failure was recurrent in three patients. Five patients had full or nearly complete recoveries; one still requires nocturnal ventilation; and one died (14%) of myocardial infarction while still requiring mechanical ventilation.
Conclusions-
Clinical ventilatory dysfunction in CIDP is usually not an indicator of poor prognosis, and many patients recover without significant permanent disability. The mortality rate is similar to intubated patients with GBS. Patients with cardiopulmonary comorbidities and acute GBS-like onset of CIDP may be at higher risk of ventilatory failure which typically responds to 'standard' treatments of CIDP. Larger prospective studies are needed to define the prevalence, clinical spectrum and significance of ventilatory involvement in CIDP and to establish guidelines for evaluation and treatment.

AB Early gastric neoplasia, which includes dysplasia and adenocarcinoma invading no more than the submucosa have been the subject of numerous studies in recent years. For example, different dysplastic phenotypes have been identified, in addition to the traditional adenomatous type, foveolar, pyloric, and tubule-neck dysplasia (associated with diffuse type carcinoma) have been recognized. Each subtype of dysplasia shows a different immuno-histochemical profile, and may vary in their risk of progression to adenocarcinoma. With regard to early gastric cancer the emergence of better diagnostic techniques allowed the development of endoscopic techniques such as endoscopic mucosal resection and endoscopic submucosal resection that nowadays allow optimal nonsurgical management. The purpose of this review is to discuss the current concepts in gastric dysplasia and early gastric cancer as they relate to diagnosis and management.

AB Ensuring health care services for populations outside the mainstream health care system is challenging for all providers. But developing the health care infrastructure to better serve such unconnected individuals is critical to their health care status, to third-party payers, to overall cost savings in public health, and to reducing health disparities.
Our increasingly sophisticated electronic technologies offer promising ways to more effectively engage this difficult to reach group and increase its access to health care resources. This process requires developing not only newer technologies but also collaboration between community leaders and health care providers to bring unconnected individuals into formal health care systems.
We present three strategies to reach vulnerable groups, outline benefits and challenges, and provide examples of successful programs. (Am J Public Health. 2011;101:1163-1167. doi:10.2105/AJPH.2010. 300003)

UNITED-STATES; CESSATION; EXPOSURE; IMPACT
AB Menthol is a cigarette flavoring that makes smoking more appealing to smokers. The US Food and Drug Administration (FDA) has regulatory authority to ban mentholated cigarettes to reduce youth uptake and encourage adult cessation. Survey findings indicate that more than half of all Americans (56.1%) and of Blacks alone (68.0% in one sample and 75.8% in another) support banning menthol. Endorsement of a ban especially by Blacks, who have the highest rates of menthol cigarette use would support FDA action to ban menthol to protect the public's health.

AB Objective: To (1) define the frequency of overall and postdischarge venous thromboembolism (VTE) after cancer surgery, (2) identify VTE risk for individual cancer operations, and (3) assess mortality rates in patients who experienced a VTE.
Summary and Background Data: Cancer is a known risk factor for VTE but less is known about VTE risk after specific cancer operations. Moreover, most cancer patients routinely receive VTE prophylaxis postoperatively while in the hospital, but few receive prolonged prophylaxis despite strong evidence it reduces postdischarge events.
Methods: From 211 ACS NSQIP hospitals, 44,656 patients undergoing surgery for 9 cancers were identified (2006-2008). The frequency of VTE within 30-days of surgery was evaluated by cancer site and categorized as occurring before or after discharge. Multivariable logistic regression models were constructed to assess risk factors associated with VTE.
Results: VTE occurred in 1.6% of all patients, most frequently after esophagogastric (4.2%) and hepatopancreaticobiliary (3.6%) surgery. Overall, 33.4% of VTEs occurred postdischarge (from 17.9% for esophagogastric to 100% for endocrine operations). Factors associated with VTE were age (>= 65 years), cancer/procedure type, metastatic disease, congestive heart failure, body mass index (BMI; >= 25 kg/m(2)), ascites, thrombocytosis (> 400,000 cells/mm(3)), albumin (< 3.0 g/dL), and operation duration (> 2 hours; all P < 0.001). Overall VTE was significantly more likely after gastrointestinal, lung, prostate, and ovarian/uterine operations (all P < 0.001). In those experiencing a VTE, mortality increased over 6-fold (8.0% vs. 1.3%; P < 0.001).
Conclusion: One-third of VTE events in cancer surgery patients occurred postdischarge. Postoperative VTE was associated with operation type. Routine postdischarge VTE prophylaxis should be considered for high-risk patients.

AB The Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia (CNTRICS) initiative, funded by an R13 from the National Institute of Mental Health, seeks to enhance translational research in treatment development for impaired cognition in schizophrenia by developing tools from cognitive neuroscience into useful measures of treatment effects on behavior and brain function. An initial series of meetings focused on the selection of a new set of tasks from cognitive neuroscience for the measurement of treatment effects on specific cognitive and neural systems. Subsequent validation and optimization studies are underway and a subset of validated measures with well-characterized psychometric properties will be generally available in 2011. This article describes results of the first meeting of the second phase of the Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia, which seeks to develop imaging biomarkers and improved animal models to enhance translational research. In this meeting, we considered issues related to the use of methods such as functional magnetic resonance imaging, electroencephalography, magnetoencephalography, and transcranial magnetic simulation as biomarkers for treatment development. We explored the biological nature of the signals measured by each method, their validity and reliability as measures of cognition-related neural activity, potential confounds related to drug effects on the signal of interest, and conceptual, methodological, and pragmatic issues related to their use in preclinical, first into human, and multicenter phase II and III studies. This overview article describes the background and goals of the meeting together with a summary of the major issues discussed in more detail in the accompanying articles appearing in this issue of Biological Psychiatry.

AB Spatial and temporal concentration gradients of chemoattractants direct many biological processes, especially the guidance of immune cells to tissue sites during homeostasis and responses to infection. Such gradients are ultimately generated by secretion of attractant proteins from single cells or collections of cells. Here we describe cell-sized chemoattractant-releasing polysaccharide microspheres, capable of mimicking chemokine secretion by host cells and generating sustained bioactive chemokine gradients in their local microenvironment. Exploiting the common characteristic of net cationic charge and reversible glycosaminoglycan binding exhibited by many chemokines, we synthesized alginate hydrogel microspheres that could be loaded with several different chemokines (including CCL21, CCL19, CXCL12, and CXCL10) by electrostatic adsorption. These polysaccharide microspheres subsequently released the attractants over periods ranging from a few hours to at least 1 day when placed in serum-containing medium or collagen gels. The generated gradients were able to attract cells more than hundreds of microns away to make contact with individual microspheres. This versatile system for chemoattractant delivery could find applications in immunotherapy, vaccines and fundamental chemotaxis studies in vivo and in vitro. (C) 2011 Elsevier Ltd.

AB Sterilization of soft biomaterials such as hydrogels is challenging because existing methods such as gamma irradiation, steam sterilization, or ethylene oxide sterilization, while effective at achieving high sterility assurance levels (SAL), may compromise their physicochemical properties and biocompatibility. New methods that effectively sterilize soft biomaterials without compromising their properties are therefore required. In this report, a dense-carbon dioxide (CO(2))-based technique was used to sterilize soft polyethylene glycol (PEG)-based hydrogels while retaining their structure and physicochemical properties. Conventional sterilization methods such as gamma irradiation and steam sterilization severely compromised the structure of the hydrogels. PEG hydrogels with high water content and low elastic shear modulus (a measure of stiffness) were deliberately inoculated with bacteria and spores and then subjected to dense CO(2). The dense CO(2)-based methods effectively sterilized the hydrogels achieving a SAL of 10(-7) without compromising the viscoelastic properties, pH, water-content, and structure of the gels. Furthermore, dense CO(2)-treated gels were biocompatible and non-toxic when implanted subcutaneously in ferrets. The application of novel dense CO(2)-based methods to sterilize soft biomaterials has implications in developing safe sterilization methods for soft biomedical implants such as dermal fillers and viscosupplements.

AB Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces selective apoptotic death of human cancer cells while sparing normal human cells. Although TRAIL holds great promise as a potential anticancer agent, some tumors develop resistance to TRAIL. Previously, we have shown that the activator protein 1 (AP-1) family member, c-Fos, is an important modulator of apoptosis. Although F-box protein 10 (FBXL10) has been implicated to regulate an AP-1 family protein, c-Jun, its role in mediating apoptotic pathways has not been previously investigated. Here, we report that FBXL10 is a transcriptional repressor of c-Fos and a target gene of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappa B)-p65 in human cancers. We demonstrate that FBXL10 is an important anti-apoptotic molecule, which directly binds and represses c-Fos promoter in order for cancer cells to resist TRAIL-induced apoptosis. FBXL10 indirectly regulates c-FLIP(L) levels via c-Fos-dependent pathways. Silencing of FBXL10 sensitizes resistant cells to TRAIL, while, overexpression of FBXL10 represses TRAIL-induced apoptosis. Moreover, our results indicate that expression of FBXL10 functions via an NF-kappa B-dependent pathway, and TRAIL or proteasome inhibitors downregulate FBXL10 via inhibiting NF-kappa B signaling. Taken together, we find a novel functional role for FBXL10 as an anti-apoptotic molecule, and describe a new apoptotic-related pathway that involves NF-kappa B/FBXL10/c-Fos/c-FLIP. Therefore, silencing FBXL10 can help overcome resistant cancer cells for pro-apoptotic therapies.

AB Objectives: There is emerging evidence that transcranial magnetic stimulation (TMS) can produce analgesic effects in clinical samples and in healthy adults undergoing experimentally induced pain; and the field of minimally invasive brain stimulation for the management of pain is expanding rapidly. Although motor cortex is the most widely used cortical target for TMS in the management of neuropathic pain, few studies have systematically investigated the analgesic effects of a full range of device parameters to provide initial hints about what stimulation intensities and frequencies are most helpful (or even potentially harmful) to patients. Further, there is considerable inconsistency between studies with respect to laboratory pain measurement procedures, TMS treatment parameters, sophistication of the sham methods, and sample sizes.
Methods: This study used a sham-controlled, within-subject, crossover design to examine the effects of 5 different TMS treatment parameters across several quantitative sensory measures in a sample of healthy adult volunteers. Sixty-five participants underwent quantitative sensory testing procedures pre and post-40-minutes of real and sham motor cortex TMS. TMS was delivered at 1 Hz 80% resting motor threshold (rMT), 1 Hz 100% rMT, 10 Hz 80% rMT, 10 Hz 100% rMT, or 50 Hz triplets at 90% of active motor threshold (intermittent theta-burst).
Results: The mean painfulness rating of real TMS stimulation itself was 3.0 (SE = 0.36) out of 10 and was significantly greater than zero [t(64) = 8.17, P < 0.0001]. The sham TMS methods used permitted matching between real and sham TMS-induced scalp sensations and participants were successfully blinded to condition (real versus sham). Findings suggest that the effects of motor cortex TMS on quantitative sensory tests in healthy adults vary across different treatment parameters with the smallest observed effect for intermittent theta-burst stimulation (Cohen's d = 0.03) and the largest for 10 Hz 100% rMT (d = 0.34).
Discussion: Overall, TMS was associated with statistically significant effects on warm and cool sensory thresholds, cold pain thresholds, suprathreshold stimulus unpleasantness ratings, and wind-up pain. With respect to device parameter effects, higher frequency stimulation seems to be associated with the most analgesic and antisensitivity effects with the exception of intermittent theta-burst stimulation. The present findings support several clinical research findings suggesting that higher TMS frequencies tend to be associated with the most clinical benefit in patients with chronic pain.

ID INSUFFICIENCY FRACTURES; ALENDRONATE THERAPY; INTERVENTION TRIAL; WOMEN;

AB Several studies have identified a specific fracture in the proximal diaphysis of the femur in patients treated with bisphosphonates. The fractures typically are sustained after a low-energy mechanism with the presence of an existing characteristic stress fracture. However, it is unclear whether these patients are best treated nonoperatively or operatively.
What is the likelihood of nonoperatively treated bisphosphonate-associated femoral stress fractures progressing to completion and during what time period? If prophylactic fixation is performed, do patients have a shorter hospital length-of-stay compared with patients having surgical fixation after fracture completion?
We retrospectively searched for patients older than 50 years receiving bisphosphonate therapy, with either incomplete, nondisplaced stress fractures or completed, displaced fractures in the proximal diaphysis of the femur between July 2002 and April 2009. After applying exclusion criteria, we identified 34 patients with a total of 40 bisphosphonate-associated fractures. The average duration of bisphosphonate use was 77 months. Twenty-eight of 40 (70%) fractures were completed, displaced fractures. Six of the 12 nondisplaced stress fractures initially were treated nonoperatively. The remaining six stress fractures were treated with prophylactic cephalomedullary nail fixation. The minimum followup was 12 months (mean, 36.5 months; range, 12-72 months).
Five of the six stress fractures treated nonoperatively progressed to fracture completion and displacement at an average of 10 months (range, 3-18 months). The average hospital stay was 3.7 days for patients treated prophylactically and 6.0 days for patients treated after fracture completion.
Our data suggest nonoperative treatment of bisphosphonate-related femoral stress fractures is not a reliable way to treat these fractures as the majority progress to fracture completion. Prophylactic fixation of femoral stress fractures also reduces total hospital admission time.

AB Purpose of review
The homing and egress of hematopoietic stem and progenitor cells (HSPCs) to and from marrow, respectively, and the proliferation and differentiation of HSPCs within marrow are complex processes critically regulated by the ordered expression and function of adhesion molecules that direct key cell-cell and cell-matrix interactions. The integral membrane molecule CD44, known primarily for its role in binding hyaluronic acid, is characteristically expressed on HSPCs. Conspicuously, human HSPCs uniquely display a specialized glycoform of CD44 known as hematopoietic cell E-/L-selectin ligand (HCELL), which is the most potent ligand for both E-selectin and L-selectin expressed on human cells. This review focuses on recent advances in our understanding of the biology of CD44 and HCELL in hematopoiesis.
Recent findings
New data indicate that CD44-mediated events in hematopoiesis are more complex than previously imagined. Ex-vivo glycan engineering has established that HCELL serves as a 'bone marrow homing receptor'. Moreover, biochemical studies now show that CD44 forms bimolecular complexes with a variety of membrane proteins, one of which is VLA-4. Engagement of CD44 or of HCELL directly induces VLA-4 activation via G-protein-dependent signaling, triggering a 'step 2-bypass pathway' of cell migration, and extravascular lodgment, in absence of chemokine receptor engagement.
Summary
Recent studies have further clarified the roles of CD44 and its glycoform HCELL in hematopoietic processes, providing key insights on how targeting these molecules may be beneficial in promoting hematopoiesis and in treating hematologic malignancies.

Waldenstrom macroglobulinemia is a distinct low-grade lymphoproliferative disease. There have been recent significant advances in understanding the underlying pathogenesis of this disease, including genetic and epigenetic regulators of tumor progression.
Recent findings
Current studies have shown that the tumor microenvironment plays a critical role in cell proliferation, dissemination, and drug resistance.
Summary
This review provides an update of the advances in the pathogenesis of factors both intrinsic (in the tumor clone) and extrinsic (in the bone marrow microenvironment) that regulate tumor progression in Waldenstrom macroglobulinemia. We next discuss novel agents that have been recently tested in clinical trials based on the advances observed in the pathogenesis of Waldenstrom macroglobulinemia.

AB Purpose of review
Vitamin D plays a role in many biochemical pathways outside of bone and calcium metabolism, including the cardiovascular system. Prior studies have linked vitamin D deficiency to hypertension, dyslipidemia, diabetes mellitus, and coronary artery disease. In this review, we summarize existing studies investigating these associations, specifically those addressing potential mechanisms, epidemiologic associations, and possible benefits of supplementation.
Recent findings
Experimental studies have demonstrated that activated vitamin D reduces neurohormonal activation, inhibits inflammation, and suppresses ventricular hypertrophy. Both retrospective and prospective observational studies have related vitamin D levels with cardiometabolic risk factors and outcomes. To date, there have been a small number of randomized controlled trials investigating the effects of vitamin D supplementation on cardiovascular structure and function, but results have been inconclusive or conflicting.
Summary
Experimental and clinical evidence suggests a link between vitamin D deficiency and cardiovascular disease. Nonetheless, it remains unclear how many of the reported associations are causal. Well designed prospective randomized controlled trials are necessary to further investigate the appropriate role of vitamin D supplementation for cardiovascular risk reduction.

AB Purpose of review
To review emerging indications for the Boston keratoprosthesis (KPro) and to discuss current research underway to improve clinical outcomes.
Recent findings
In addition to multiple failed corneal grafts, other ocular conditions for which the Boston KPro has been used include herpetic keratitis, aniridia, autoimmune ocular disorders, and pediatric corneal opacities. In the recent years, the KPro has been implanted for various other conditions and has also been explored as a cost-effective treatment for severe corneal diseases internationally. Cicatricial and inflammatory ocular conditions remain the most difficult cases for KPro use but studies investigating various immunomodulators and biologic materials for improved retention are ongoing. Postoperative management of glaucoma is critical for preserving the visual gains achieved with the Boston KPro. Current studies are evaluating novel devices for intraocular pressure measurement.
Summary
Accrued experience with the Boston KPro has demonstrated its versatility but also the difficulties that remain in postoperative management. With many studies underway to improve cost-effectiveness, intra-operative and postoperative management, keratoprostheses will be made increasingly available to those countries most in need.

AB Objective: To compare, in patients with suspicion of coronary artery disease (CAD) and low heart rates, image quality, diagnostic performance, and radiation dose values of prospectively and retrospectively electrocardiography (ECG)-gated dual-source computed tomography coronary angiography (CTCA) for the diagnosis of significant coronary stenoses.
Materials and methods: Two-hundred consecutive patients with heart rates <= 70 bpm were retrospectively enrolled; 100 patients undergoing prospectively ECG-gated CTCA (group 1) and 100 patients undergoing retrospectively-gated CTCA (group 2). Coronary artery segments were assessed for image quality and significant luminal diameter narrowing. Sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and accuracy of both CTCA groups were determined using conventional catheter angiography (CCA) as reference standard. Radiation dose values were calculated.
Results: Both groups were comparable regarding gender, body weight, cardiovascular risk profile, severity of CAD, mean heart rate, heart rate variability, and Agatston score (all p > 0.05). There was no significant difference in the rate of non-assessable coronary segments between group 1 (1.6%, 24/1404) and group 2 (1.4%, 19/1385; p = 0.77); non-diagnostic image quality was significantly (p < 0.001) more often attributed to stair step artifacts in group 1. Segment-based sensitivity, specificity, PPV, NPV, and accuracy were 98%, 98%, 88%, 100%, and 100% among group 1; 96%, 99%, 90%, 100%, and 98% among group 2, respectively. Parameters of diagnostic performance were similar (all p > 0.05). Mean effective radiation dose of prospectively ECG-gated CTCA (2.2 +/- 0.4 mSv) was significantly (p < 0.0001) smaller than that of retrospectively ECG-gated CTCA (8.1 +/- 0.6 mSv).
Conclusion: Prospectively ECG-gated CTCA yields similar image quality, performs as accurately as retrospectively ECG-gated CTCA in patients having heart rates <= 70 bpm while being associated with a lower mean effective radiation dose. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

AB Introduction: Vinca alkaloid agents have been widely used in several different types of malignancies. However, cancer cells, ultimately, develop resistance to these agents. Therefore, the development of new agents with improved efficacy is warranted. Recently, a new synthetic vinca alkaloid, vinflunine, was developed through the addition of two fluor molecules by superacidic chemistry.
Areas covered: The authors describe the development of the new vinca alkaloid vinflunine from preclinical studies to the late-stage clinical trials, highlighting the most important clinical and safety data of vinflunine. In vitro and in vivo studies have shown a superior efficacy of vinflunine over other vinca alkaloids and with an improved safety profile. Early clinical trials have demonstrated a significant activity of vinflunine against different malignancies. Phase III trials showed that vinflunine increases survival in patients with advanced transitional cell carcinoma of the urothelium (TCCU) tract treated in the second-line and is as effective as docetaxel in second-line NSCLC.
Expert opinion: Vinflunine is currently approved in Europe for the treatment of second-line TCCU and is currently being developed in other malignancies. It has been shown to have predictable and manageable adverse effects, such as neutropenia, anemia, constipation and fatigue.

AB Meta-analyses of large-scale association studies typically proceed solely within one data type and do not exploit the potential complementarities in other sources of molecular evidence. Here, we present an approach to combine heterogeneous data from genome-wide association (GWA) studies, protein-protein interaction screens, disease similarity, linkage studies, and gene expression experiments into a multi-layered evidence network which is used to prioritize the entire protein-coding part of the genome identifying a shortlist of candidate genes. We report specifically results on bipolar disorder, a genetically complex disease where GWA studies have only been moderately successful. We validate one such candidate experimentally, YWHAH, by genotyping five variations in 640 patients and 1,377 controls. We found a significant allelic association for the rs1049583 polymorphism in YWHAH (adjusted P = 5.6e-3) with an odds ratio of 1.28 [1.12-1.48], which replicates a previous case-control study. In addition, we demonstrate our approach's general applicability by use of type 2 diabetes data sets. The method presented augments moderately powered GWA data, and represents a validated, flexible, and publicly available framework for identifying risk genes in highly polygenic diseases.

AB Objective : There is interest in using cortical auditory evoked potentials (CAEPs)to evaluate hearing aid fittings and experience-related plasticity associated with amplification; however, little is known about hearing aid signal processing effects on these responses. The purpose of this study was to determine the effect of clinically relevant hearing aid gain settings, and the resulting in-the-canal signal-to-noise ratios (SNRs), on the latency and amplitude of P1, N1, and P2 waves. Design & Sample : Evoked potentials and in-the-canal acoustic measures were recorded in nine normal-hearing adults in unaided and aided conditions. In the aided condition, a 40-dB signal was delivered to a hearing aid programmed to provide four levels of gain (0, 10, 20, and 30 dB). As a control, unaided stimulus levels were matched to aided condition outputs (i.e. 40, 50, 60, and 70 dB)for comparison purposes. Results : When signal levels are defined in terms of output level, aided CAEPs were surprisingly smaller and delayed relative to unaided CAEPs, probably resulting from increases to noise levels caused by the hearing aid. Discussion : These results reinforce the notion that hearing aids modify stimulus characteristics such as SNR, which in turn affects the CAEP in a way that does not reliably reflect hearing aid gain.

AB Uterine adenosarcomas are uncommon mixed Mullerian neoplasms, most commonly arising in the uterine corpus. A new Federation of International Gynecologic Organization staging system for these tumors has recently been implemented. This staging system is an improvement on the earlier generic application of the 1988 Federation of International Gynecologic Organization staging system for endometrial cancer to adenosarcoma. Herein, we report 3 uterine adenosarcomas with unusual features. For 2 of these, no specific staging guidelines are provided by either the earlier or, more importantly, the new staging system. The first case is of an adenosarcoma arising in the eutopic endometrium with involvement of underlying adenomyosis without myometrial invasion; the second originated in a mural adenomyoma in the absence of eutopic endometrial involvement; and the third case encompassed synchronous endometrial and extrauterine (peritoneal) neoplasms. Such cases are rare, and there is insufficient evidence to be definitive about staging. Thus, we suggest a descriptive reporting strategy for adenosarcomas with these unusual features. We also propose a reporting nomenclature for such cases to ensure standardization such that they can be adequately recorded in synoptic reporting protocols. This will facilitate reliable data collection such that an evidence-based staging system for these scenarios may be derived.

AB One branch of the tryptophan catabolic cascade is the kynurenine pathway, which produces neurotoxic [3-hydroxykynurenine (3-OHKY), quinolinic acid] and neuroinhibitory (kynurenic acid) compounds. Kynurenic acid acts as a competitive antagonist at the glycine site of N-methyl-D-asparate receptors at high concentrations and as a non-competitive antagonist on the alpha(7)-nicotinic acetylcholine receptor at low concentrations. Kynurenine compounds also influence cognitive functions known to be disrupted in schizophrenia. Alterations in tryptophan metabolism are therefore of potential significance for the pathophysiology of this disorder. In this paper, tryptophan metabolites were measured from plasma using high-pressure liquid chromatography coupled with electrochemical coulometric array detection, and relationships were tested between these metabolic signatures and clinical symptoms for 25 first-episode neuroleptic-naive schizophrenia patients. Blood samples were collected and clinical and neurological symptoms were rated at baseline and again at 4 wk following initiation of treatment. Level of 3-OHKY and total clinical symptom scores were correlated when patients were unmedicated and neuroleptic-naive, and this relationship differed significantly from the correlation observed for patients 4 wk after beginning treatment. Baseline psychosis symptoms were predicted only by neurological symptoms. Moreover, baseline 3-OHKY predicted clinical change at 4 wk, with the lowest concentrations of 3-OHKY being associated with the greatest improvement in symptoms. Taken together, our findings suggest a neurotoxic product of tryptophan metabolism, 3-OHKY, predicts severity of clinical symptoms during the early phase of illness and before exposure to antipsychotic drugs. Baseline level of 3-OHKY may also predict the degree of clinical improvement following brief treatment with antipsychotics.

AB Objectives: To investigate whether the major fungal multidrug efflux systems (MESs) affect the efficiency of methylene blue (MB)-mediated antimicrobial photodynamic inactivation (APDI) in pathogenic fungi and test specific inhibitors of these efflux systems to potentiate APDI.
Methods: Candida albicans wild-type and mutants that overexpressed two classes of MESs [ATP-binding cassette (ABC) and major facilitator superfamily (MFS)] were tested for APDI using MB as the photosensitizer with and without addition of MES inhibitors. The uptake and cytoplasm localization of photosensitizer were achieved using laser confocal microscopy.
Results: ABC MES overexpression reduced MB accumulation and APDI killing more than MFS MES overexpression. Furthermore, by combining MB APDI with the ABC inhibitor verapamil, fungal killing and MB uptake were potentiated, while by combining MB APDI with the MFS inhibitor INF(271), fungal killing and MB uptake were inhibited. This latter surprising finding may be explained by the hypothesis that the MFS channel can also serve as an uptake mechanism for MB.
Conclusions: The ABC pumps are directly implicated in MB efflux from the cell cytoplasm. Both the influx and efflux of MB may be regulated by MFS systems, and blocking this gate before incubation with MB can decrease the uptake and APDI effects. An ABC inhibitor could be usefully combined with MB APDI for treating C. albicans infections.

AB P>Aim
To monitor microbial shifts during dental biofilm re-development.
Materials and methods
Supra- and subgingival plaque samples were taken separately from 28 teeth in 38 healthy and 17 periodontitis subjects at baseline and immediately after tooth cleaning. Samples were taken again from seven teeth in randomly selected quadrants during 1, 2, 4 and 7 days of no oral hygiene. Samples were analysed using checkerboard DNA-DNA hybridization. Species counts were averaged within subjects at each time point. Significant differences in the counts between healthy and periodontitis subjects were determined using the Mann-Whitney test.
Results
The total supra- and subgingival counts were significantly higher in periodontitis on entry and reached or exceeded the baseline values after day 2. Supragingival counts of Veillonella parvula, Fusobacterium nucleatum ss vincentii and Neisseria mucosa increased from 2 to 7 days. Subgingival counts were greater for Actinomyces, green and orange complex species. Significant differences between groups in supragingival counts occurred for 17 of 41 species at entry, 0 at day 7; for subgingival plaque, these values were 39/41 taxa at entry, 17/41 at day 7.
Conclusions
Supragingival plaque re-development was similar in periodontitis and health, but subgingival species recolonization was more marked in periodontitis.

AB Many sentences with two quantifiers exhibit a phenomenon known as "quantifier scope ambiguity." Consider the example A unicorn ran through every garden, which contains the quantifiers "a" and "every." Most speakers of English agree that it may refer to one or more than one unicorn. Very little previous work has evaluated the ability of brain-damaged or aphasic patients to interpret such sentences. We administered a sentence-reading task with picture verification to a group of semantic dementia patients (N = 5) and a matched group of cognitively normal controls (N = 23). Controls exhibited a tendency to interpret the word every as having wide scope regardless of the order of quantifiers, as evidenced by decreased reaction time and increased accuracy when verifying pictures that required this interpretation. This bias was attenuated by increasing age and by the presence of semantic dementia. Furthermore, higher FAS fluency scores were associated with slower responses and more errors, while higher semantic fluency scores were associated with the opposite pattern. These findings fit best with a model in which the initial products of linguistic analysis are underspecified and biases in their interpretation arise subsequently through frontally mediated logical or pragmatic reasoning.

AB Primary varicella-zoster virus (VZV) infection in humans produces varicella (chickenpox), after which the virus becomes latent in ganglionic neurons. Analysis of the physical state of viral nucleic acid and virus gene expression during latency requires postmortem acquisition of fresh human ganglia. To provide an additional way to study the VZV-host relationship in neurons, we developed an in vitro model of infected differentiated human neural stem cells (NSCs). NSCs were induced to differentiate in culture dishes coated with poly-L-lysine and mouse laminin in the presence of fibroblast growth factor 2 (FGF-2), nerve growth factor (NGF), brain-derived neurotropic factor (BDNF), dibutyryl cyclic AMP, and retinoic acid. Immunostaining with neuronal (MAP2a and beta-tubulin), astrocyte (GFAP), and oligodendrocyte (CNPase) markers revealed that differentiated neurons constituted approximately 90% of the cell population. These neurons were maintained in culture for up to 8 weeks. No cytopathic effect (CPE) developed in neurons infected with cell-free VZV (Zostavax vaccine) compared to human fetal lung fibroblasts infected with VZV. Weeks later, VZV DNA virus-specific transcripts (open reading frames [ORFs] 21, 29, 62, and 63) were detected in infected neurons, and dual immunofluorescence staining revealed the presence of VZV IE63 and gE exclusively in healthy-appearing neurons, but not in astrocytes. Neither the tissue culture medium nor a homogenate prepared from VZV-infected neurons produced a CPE in fibroblasts. VZV induced apoptosis in fibroblasts, as shown by activation of caspase 3 and by terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling (TUNEL) staining, but not in neurons. This model provides a unique in vitro system to study the VZV-neuronal relationship.

AB Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1) transforms rodent fibroblasts and is expressed in most EBV-associated malignancies. LMP1 (transformation effector site 2 [TES2]/C-terminal activation region 2 [CTAR2]) activates NF-kappa B, p38, Jun N-terminal protein kinase (JNK), extracellular signal-regulated kinase (ERK), and interferon regulatory factor 7 (IRF7) pathways. We have investigated LMP1 TES2 genome-wide RNA effects at 4 time points after LMP1 TES2 expression in HEK-293 cells. By using a false discovery rate (FDR) of <0.001 after correction for multiple hypotheses, LMP1 TES2 caused >2-fold changes in 1,916 mRNAs; 1,479 RNAs were upregulated and 437 were downregulated. In contrast to tumor necrosis factor alpha (TNF-alpha) stimulation, which transiently upregulates many target genes, LMP1 TES2 maintained most RNA effects through the time course, despite robust and sustained induction of negative feedback regulators, such as I kappa B alpha and A20. LMP1 TES2-regulated RNAs encode many NF-kappa B signaling proteins and secondary interacting proteins. Consequently, many LMP1 TES2-regulated RNAs encode proteins that form an extensive interactome. Gene set enrichment analyses found LMP1 TES2-upregulated genes to be significantly enriched for pathways in cancer, B- and T-cell receptor signaling, and Toll-like receptor signaling. Surprisingly, LMP1 TES2 and I kappa B alpha superrepressor coexpression decreased LMP1 TES2 RNA effects to only 5 RNAs, with FDRs of <0.001-fold and >2-fold changes. Thus, canonical NF-kappa B activation is critical for almost all LMP1 TES2 RNA effects in HEK-293 cells and a more significant therapeutic target than previously appreciated.

AB Oxygen-dependent regulation of the transcription factor HIF-1 alpha relies on a family of prolyl hydroxylases (PHDs) that hydroxylate hypoxia-inducible factor 1 alpha (HIF-1 alpha) protein at two prolines during normal oxygen conditions, resulting in degradation by the proteasome. During low-oxygen conditions, these prolines are no longer hydroxylated and HIF-1 alpha degradation is blocked. Hypoxia-induced miRNA-210 (miR-210) is a direct transcriptional target of HIF-1 alpha, but its complete role and targets during hypoxia are not well understood. Here, we identify the enzyme glycerol-3-phosphate dehydrogenase 1-like (GPD1L) as a novel regulator of HIF-1 alpha stability and a direct target of miR-210. Expression of miR-210 results in stabilization of HIF-1 alpha due to decreased levels of GPD1L resulting in an increase in HIF-1 alpha target genes. Altering GPD1L levels by overexpression or knockdown results in a decrease or increase in HIF-1 alpha stability, respectively. GPD1L-mediated decreases in HIF-1 alpha stability can be reversed by pharmacological inhibition of the proteasome or PHD activity. When rescued from degradation by proteasome inhibition, elevated amounts of GPD1L cause hyperhydroxylation of HIF-1 alpha, suggesting increases in PHD activity. Importantly, expression of GPD1L attenuates the hypoxic response, preventing complete HIF-1 alpha induction. We propose a model in which hypoxia-induced miR-210 represses GPD1L, contributing to suppression of PHD activity, and increases of HIF-1 alpha protein levels.

AB Foxp3 is a nuclear transcription factor that is both a tumor suppressor factor and regulator of T-regulatory cell (Treg) function, and is a potential therapeutic target in both autoimmunity and cancer. In order to distinguish molecular pathways responsible for these separate Foxp3 functions, deletion mutants of Foxp3 proteins were transduced and analyzed for cytotoxic activity in human cancer cell lines Skov3, MDA-MB-231, MCF-7 and Jurkat. Human Foxp3 cDNA mutants were amplified and ligated to produce plasmids for direct cell transfection. Constructs were produced and confirmed by DNA sequencing. Lipofectamine 2000 was used for plasmid transfection. Foxp3 cells were then examined. The results of our experiments reveal retention of tumor suppressor function in the absence of NFAT binding and transcriptional activation required for Treg function. Our results have significant implications for the design of autoimmune and cancer therapies that target Foxp3 and Treg cells.

AB The present study examined whether a moderately aversive abdominal threat would lead to greater enhancement in affect-and pain-related defensive responding as indexed by the acoustic startle reflex (ASR) and nociceptive flexion reflex (NFR) in women compared to men. We also predicted sex differences in threat-related autonomic arousal measured by skin conductance responses (SCRs) to acoustic startle and noxious sural nerve stimulation. Unpredictable threat was manipulated by alternating 30-second safe ("no abdominal stimulation will be given'') and threat ("abdominal stimulation may occur at anytime'') periods. The experiment consisted of 2 blocks, each containing 4 safe and 4 threat periods in which the ASR or NFR was randomly probed 9-21 seconds following period onset. Unpredictable abdominal threat potentiated both ASR and NFR responses compared to periods signaling safety. SCRs to acoustic startle probes and noxious sural nerve stimulation were also significantly elevated during the threat vs safe periods. No sex differences in ASR or startle-evoked SCRs emerged. However, nociceptive responding was moderated by sex; females showed significant increases in NFR magnitudes across both safe and threat periods compared to males. Females also showed greater threat-potentiated SCRs to sural nerve stimulation than males. Our findings indicate that both affect-and pain-related defense and arousal systems are strongly influenced by threat of an aversive, unpredictable event, a situation associated with anticipatory anxiety. Females, compared to males, showed greater nociceptive responding and pain modulation when exposed to an unpredictable threatening context, whereas affect-driven ASR responses showed no such sex differentiation.

AB Non-medical use of prescription drugs (NMUPD) is one of the fastest growing forms of illicit drug use, with research indicating that college students represent a particularly high risk population. The current study examined demographic characteristics, health/mental health, substance misuse, and rape experiences as potential risk correlates of NMUPD among a national sample of college women (N = 2000). Interviews were conducted via telephone using Computer-Assisted Telephone Interviewing technology. NMUPD was assessed by asking if, participants had used a prescription drug non-medically in the past year. NMUPD was endorsed by 7.8% of the sample (n = 155). Although incapacitated and drug-alcohol facilitated rape were associated with NMUPD in the initial model, the final multivariable model showed that only lifetime major depression and other forms of substance use/abuse were significantly uniquely associated with an increased likelihood of NMUPD. Implications for primary and secondary prevention and subsequent research are addressed. Published by Elsevier Ltd.

AB The current investigation evaluated (1) the incremental predictive validity of non-judgmental acceptance in terms of alcohol use coping motives and (2) the mediating role of non-judgmental acceptance in the association between posttraumatic stress symptom severity and alcohol use coping motives. Participants included 153 (79 women) adults who reported exposure to at least one DSM-IV PTSD Criterion A traumatic life event and alcohol use in the past month. Non-judgmental acceptance emerged as a significant incremental predictor of alcohol use coping motives. Furthermore, non-judgmental acceptance partially mediated the association between posttraumatic stress symptom severity and alcohol use coping motives. Theoretical and clinical implications of the findings are discussed with regard to better understanding the co-occurrence of posttraumatic stress and alcohol use disorders. Published by Elsevier Ltd.

AB Co-occurring substance abuse and mental illness is prevalent among criminal offenders, but little is mown about risk factors for these co-occurring disorders (COD) in community corrections population. To identify risk factors for COD in community corrections offenders, we analyzed assessment data from 5,595 offenders maintained under community supervision at a substance use diversion program. Three groups, offenders with substance use disorders who were taking psychotropic medications (SUPM), offenders with a substance use disorder (SUD) only and controls were compared. Logistic regressions were used to identify predictors of SUPM versus SUD only and controls. SUPM status was predicted by being White or Female, having some medical insurance (private or government aided), being unemployed, prior history of abuse/trauma. and prior history of suicidal ideation or behavior.
Offenders with substance use disorders and co-occurring psychiatric problems face salient social risk that may need to be targeted through integrated services. Published by Elsevier Ltd.

AB Aims: Emerging research may soon lead to improved quit rates via genetically-tailored smoking cessation treatment. The purpose of this study was to explore individuals' beliefs and attitudes about genetic testing in this context, and how these may differ across racial groups.
Design: Two site qualitative study.
Methods: Eleven focus groups were conducted in 2007 with 51 Black and 55 White adult participants in Montgomery, AL and Baltimore, MD.
Measurements: Questions were asked about smoking as an addiction, the role of genetics in nicotine addiction susceptibility, and undergoing genetic testing to receive tailored smoking cessation treatment. Data were analyzed using content analysis.
Findings: Most participants believed that smoking was an addiction yet were unwilling to endorse the notion that genetics played a role in nicotine addiction susceptibility. However, 91% of White participants and 62% of Black participants indicated that they would likely take a genetic test that would match them to their optimal smoking cessation treatment. The primary potential benefit was a vague sense that additional knowledge about oneself would be of value. Primary barriers included disinterest and skepticism about the test, unwillingness to believe that genetics played a role in nicotine addiction or treatment response, and concerns about psychological consequences.
Conclusions: The majority of participants, particularly Black participants, did not believe that genetics played a significant role in nicotine addiction susceptibility but were willing to undergo genetic testing. Participants identified some benefit to tailoring smoking treatment by genotype. However, participants also expressed skepticism about the test and concerns about its consequences; these issues would need to be addressed in the clinical encounter. (C) 2011 Elsevier Ltd.

AB The ubiquitously expressed calpains-1 and -2 belong to a family of calcium-dependent intracellular cysteine proteases. Both calpains are heterodimers consisting of a large catalytic subunit and a small regulatory subunit encoded by the gene Capn4. Ablation of the calpain small subunit eliminates calpain activity and leads to embryonic lethality. We previously created osteoblast-specific Capn4 knockout mice to investigate a physiological role for the calpain small subunit in cells of the osteoblast lineage. Deletion of Capn4 reduced trabecular and cortical bone, mainly due to impaired proliferation and differentiation of cells of the osteoblast lineage. To further investigate an underlining mechanism by which osteoblast-specific Capn4 knockout mice develop an osteoporotic bone phenotype, we established osteoblastic cell lines stably expressing either control or Capn4 RNA interference for this study. Capn4 knockdown cells showed reduced cell proliferation, accumulation of total and phosphorylated cyclin-dependent kinase inhibitor 1B (p27(Kip1)) on serine 10, and reduced phosphorylation of retinoblastoma protein on threonine 821. Moreover, ablation of Capn4 increased 27 (Kip1) mRNA levels, likely due to stabilized binding of Akt to protein phosphatase 2A, which presumably results in reduced phosphorylation of Akt on S473 and forkhead Box O (FoxO) 3A on T32. Collectively, calpain regulates cell proliferative function by modulating both transcription and degradation of p27(Kip1) in osteoblasts. In conclusion, calpain is a critical modulator for regulation of p27(Kip1) in cells of the osteoblast lineage.

AB This meta-analysis assessed efficacy of pharmacologic and psychological interventions for treatment of perinatal depression. A systematic review identified 27 studies, including open trials (n = 9), quasi-randomized trials (n = 2), and randomized controlled trials (n = 16) assessing change from pretreatment to posttreatment or comparing these interventions to a control group. Uncontrolled and controlled effect sizes were assessed in separate meta-analyses. There was significant improvement in depressive symptoms from pretreatment to posttreatment, with an uncontrolled overall effect size (Hedges' g) of 1.61 after removal of outliers and correction for publication bias. Symptom levels at posttreatment were below cutoff levels indicative of clinically significant symptoms. At posttreatment, intervention groups demonstrated significantly greater reductions in depressive symptoms compared to control groups, with an overall controlled effect size (Hedges' g) of 0.65 after removal of outliers. Individual psychotherapy was superior to group psychotherapy with regard to changes in symptoms from pretreatment to posttreatment. Interventions including an interpersonal therapy component were found to have greater effect sizes, compared to control conditions, than interventions including a cognitive-behavioral component. Implications of the findings for clinical practice and future research are discussed. (C) 2011 Elsevier Ltd. All rights reserved.

AB Purpose of review
To present an updated summary of the relationship between inflammation and localized and generalized bone loss in the rheumatic diseases.
Recent findings
In addition to the well established role of inflammatory cytokines in promoting enhanced osteoclast function and bone loss, recent work has discovered the cytokine milieu may also inhibit osteoblast function and bone repair. The WNT and bone morphogenetic protein pathways provide molecular links between inflammation and altered bone homeostasis in chronic inflammatory states. These pathways and others have been the targets of emerging therapies for the management of inflammatory bone loss.
Summary
Inflammation and bone loss are linked through a number of molecular pathways. Both of these processes need to be addressed when designing an effective treatment strategy for the rheumatic diseases.

AB WASp family proteins serve as conserved regulators of branched microfilament array formation via the Arp2/3 actin polymerization machinery. We have identified a specific role during spermatogenesis for the Drosophila WASp homolog (Wsp) and associated elements. Spermatogenesis within the fly testis is carried out in cysts, where a pair of somatic cyst cells encloses differentiating sperm. The final phase of the process involves the attachment of matured cysts to a specialized epithelium at the base of the testis, followed by release of individual motile spermatids into the adjoining seminal vesicle. Wsp mutant cysts contain fully mature sperm, but spermatid release does not occur, resulting in male sterility. Our data suggest that the Wsp-Arp2/3-based machinery acts in the cyst cells to influence proper microfilament organization and to enable cyst attachment to the base of the testis. Wsp activity in this context is mediated by the small GTPase Cdc42. Involvement of the cell surface protein Sticks and stones and the Wsp adapter protein D-WIP (Vrp1) is also crucial. In parallel, we demonstrate that N-WASp (Wasl), the major mammalian WASp family protein, is required in the somatic Sertoli cells of the mouse testis for sperm maturation. A requirement for WASp-based activity in somatic support cells therefore appears to be a universal feature of spermatogenesis.

TI Analysis of Multiple-cycle Data From Couples Undergoing In Vitro
Fertilization Methodologic Issues and Statistical Approaches
SO EPIDEMIOLOGY
LA English
DT Article
ID OUTCOMES; MODELS
AB The number of in vitro fertilization (IVF) cycles in the United States increased from fewer than 46,000 in 1995 to more than 120,000 in 2005. IVF and other assisted reproductive technology (ART) data are routinely collected and used to identify outcome predictors. However, researchers do not always make full use of the data due to their complexity. Design approaches have included restriction to first-cycle attempts only, which reduces power and identifies effects only of those factors associated with initial success. Many statistical techniques have been used or proposed for analysis of IVF data, ranging from simple t tests to sophisticated models designed specifically for IVF. We applied several of these methods to data from a prospective cohort of 2687 couples undergoing ART from 1994 through 2003. Results across methods are compared and the appropriateness of the various methods is discussed with the intent to illustrate methodologic validity. We observed a remarkable similarity of coefficient estimates across models. However, each method for dealing with multiple cycle data relies on assumptions that may or may not be expected to hold in a given IVF study. The robustness and reported magnitude of effect for individual predictors of IVF success may be inflated or attenuated due to violation of statistical assumptions, and should always be critically interpreted. Given that risk factors associated with IVF success may also advance our understanding of the physiologic processes underlying conception, implantation, and gestation, the application of valid methods to these complex data is critical.

AB Posttraumatic stress disorder (PTSD) can be a chronic and disabling illness with a limited response to antidepressant treatment, particularly in the case of combat-induced PTSD. The purpose of this study is to review randomized controlled and open-label trials of atypical antipsychotics for the treatment of PTSD. We conducted PUBMED and PILOTS database searches for clinical trials of atypical antipsychotic medications for PTSD in May 2010. Eighteen clinical trials (10 double-blind placebo-controlled, eight open-label) of atypical antipsychotics for PTSD were found and reviewed. Effect sizes of double-blind placebo-controlled trials were small, but were positive for risperidone and quetiapine. Intrusive and hypervigilance symptom subscales showed the most improvement. We concluded that atypical antipsychotic medications have a modest benefit for the treatment of PTSD. Larger randomized controlled trials are needed to clarify the potential utility of these medications in the treatment of PTSD and more rigorous examination of metabolic side effects is warranted.

AB To assess whether early changes in Hamilton Depression Rating Scale-17 anxiety/somatization items predict remission in two controlled studies of Hypericum perforatum (St John's wort) versus selective serotonin reuptake inhibitors for major depressive disorder. The Hypericum Depression Trial Study Group (National Institute of Mental Health) randomized 340 patients to Hypericum, sertraline, or placebo for 8 weeks, whereas the Massachusetts General Hospital study randomized 135 patients to Hypericum, fluoxetine, or placebo for 12 weeks. The investigators examined whether remission was associated with early changes in anxiety/somatization symptoms. In the National Institute of Mental Health study, significant associations were observed between remission and early improvement in the anxiety (psychic) item (sertraline arm), somatic (gastrointestinal item; Hypericum arm), and somatic (general) symptoms (placebo arm). None of the three treatment arms of the Massachusetts General Hospital study showed significant associations between anxiety/somatization symptoms and remission. When both study samples were pooled, we found associations for anxiety (psychic; selective serotonin reuptake inhibitors arm), somatic (gastrointestinal), and hypochondriasis (Hypericum arm), and anxiety (psychic) and somatic (general) symptoms (placebo arm). In the entire sample, remission was associated with the improvement in the anxiety (psychic), somatic (gastrointestinal), and somatic (general) items. The number and the type of anxiety/somatization items associated with remission varied depending on the intervention. Early scrutiny of the Hamilton Depression Rating Scale-17 anxiety/somatization items may help to predict remission of major depressive disorder.

AB P>The aim of this study was to identify the factors related to prosthetic restoration in patients with shortened dental arches (SDA). SDA patients with 2-12 missing occlusal units were consecutively enrolled from seven university-based dental hospitals in Japan. Of the 145 subjects (mean age; 63 center dot 4 years), 41% chose no treatment and 59% sought to replace their edentulous spaces with removable partial dentures or implant-supported fixed partial dentures. Restoration decisions were related to tooth loss patterns. Only 3% of subjects missing just second molar(s) sought to receive prosthetic treatment, while the percentage increased to 58% in subjects who were missing first and second molars and 93% in subjects missing premolar(s). Logistic regression analyses found that young age, increased number of missing occlusal units, asymmetric arch and presence of chewing complaint were significant predictors for prosthetic restoration (P < 0 center dot 05). Increased number of missing occlusal units and asymmetric arch were significant predictors for the presence of chewing complaint (P < 0 center dot 05). These results suggest that perceived impairment of chewing ability owing to missing occlusal units is a critical factor for prosthetic restoration in SDA patients.

ID RIGHT HEMICOLECTOMY; DISTANT METASTASIS
AB Background: Carcinoid tumors of the appendix are rare, and as such there are few data guiding their optimal treatment.
Methods: The analysis included all patients with malignant, typical carcinoid tumor of the appendix for whom complete data were available in the Surveillance, Epidemiology, and End Results database between 1988 and 2003. Clinicopathologic factors predicting lymph node (LN) involvement and survival were determined.
Results: LN metastases were present in 44 of 89 patients (49%), including 4 of 27 patients (15%) with tumors <= 1.0 cm, 16 of 34 patients (47%) with tumors > 1.0 cm but <= 2.0 cm, and 24 of 28 patients (86%) with tumors > 2.0 cm. Increasing tumor size predicted LN involvement, whereas age, gender, and depth of tumor invasion did not. Excluding patients with distant metastasis (DM), the 10-year overall survival rates of patients with positive LNs and tumor sizes <= 1.0 cm, > 1.0 cm but <= 2.0 cm, and > 2.0 cm were 100%, 92%, and 91%, respectively.
Conclusions: Right hemicolectomy should be considered for patients with appendiceal carcinoid tumors > 1.0 cm in size given their high incidence of LN metastases and limited data concerning the natural history of unresected LN metastases. J. Surg. Oncol. 2011;104:41-44. (C) 2011 Wiley-Liss, Inc.

AB Purpose: Radical prostatectomy and brachytherapy are widely used treatments for favorable risk prostate cancer. We estimated the risk of prostate cancer specific mortality following radical prostatectomy or brachytherapy in men with low or intermediate risk prostate cancer using prospectively collected data.
Materials and Methods: The study cohort comprised 5,760 men with low risk prostate cancer (prostate specific antigen 10 ng/ml or less, clinical category T1c or 2a and Gleason score 6 or less), and 3,079 with intermediate risk prostate cancer (prostate specific antigen 10 to 20 ng/ml, clinical category T2b or T2c, or Gleason score 7). Competing risks multivariable regression was performed to assess the risk of prostate cancer specific mortality after radical prostatectomy or brachytherapy, adjusting for age, year of treatment, cardiovascular comorbidity and known prostate cancer prognostic factors.
Results: After a median followup of 4.2 years (IQR 2.0 - 7.4) for low risk and 4.8 years (IQR 2.2-8.1) for intermediate risk men, there was no significant difference in the risk of prostate cancer specific mortality among low risk (adjusted hazard ratio 1.62, 95% CI 0.59-4.45, p = 0.35) or intermediate risk men (AHR 2.30, 95% CI 0.95-5.58, p = 0.07) treated with brachytherapy compared with radical prostatectomy. The only factor associated with an increased risk of prostate cancer specific mortality (AHR 1.05, 95% CI 1.01-1.10, p = 0.03) was increasing age at treatment in intermediate risk men.
Conclusions: The risk of prostate cancer specific mortality in men with low or intermediate risk prostate cancer was not significantly different following radical prostatectomy vs brachytherapy.

TI Dutasteride Reduces Prostate Size and Prostate Specific Antigen in Older
Hypogonadal Men With Benign Prostatic Hyperplasia Undergoing
Testosterone Replacement Therapy

AB Purpose: Benign prostatic hyperplasia and hypogonadism are common disorders in aging men. There is concern that androgen replacement in older men may increase prostate size and symptoms of benign prostatic hyperplasia. We examined whether combining dutasteride, which inhibits testosterone to dihydrotestosterone conversion, with testosterone treatment in older hypogonadal men with benign prostatic hyperplasia reduces androgenic stimulation of the prostate compared to testosterone alone.
Materials and Methods: We conducted a double-blind, placebo controlled trial of 53 men 51 to 82 years old with symptomatic benign prostatic hyperplasia, prostate volume 30 cc or greater and serum total testosterone less than 280 ng/dl (less than 9.7 nmol/l). Subjects were randomized to daily transdermal 1% T gel plus oral placebo or dutasteride for 6 months. Testosterone dosing was adjusted to a serum testosterone of 500 to 1,000 ng/dl. The primary outcomes were prostate volume measured by magnetic resonance imaging, serum prostate specific antigen and androgen levels.
Results: A total of 46 subjects completed all procedures. Serum testosterone increased similarly into the mid-normal range in both groups. Serum dihydrotestosterone increased in the testosterone only but decreased in the testosterone plus dutasteride group. In the testosterone plus dutasteride group prostate volume and prostate specific antigen (mean +/- SEM) decreased 12% +/- 2.5% and 35% +/- 5%, respectively, compared to the testosterone only group in which prostate volume and prostate specific antigen increased 7.5% +/- 3.3% and 19% +/- 7% (p = 0.03 and p = 0.008), respectively, after 6 months of treatment. Prostate symptom scores improved in both groups.
Conclusions: Combined treatment with testosterone plus dutasteride reduces prostate volume and prostate specific antigen compared to testosterone only. Coadministration of a 5 alpha-reductase inhibitor with testosterone appears to spare the prostate from androgenic stimulation during testosterone replacement in older, hypogonadal men with symptomatic benign prostatic hyperplasia.

MANAGEMENT; PERFUSION; THERAPY
AB BACKGROUND AND IMPORTANCE: This article describes delayed endovascular revascularization in a patient with clinical and radiographic evidence of posterior circulation hemodynamic failure in the setting of intracranial occlusive lesions.
CLINICAL PRESENTATION: A 48-year-old man presented with a 6-week history of progressive headache, nausea, and ataxia. Bilateral intracranial vertebral artery occlusions and a left posterior inferior cerebellar artery stroke were diagnosed, and the patient began warfarin therapy. Despite these measures, the patient developed dense lower cranial neuropathies, including severe dysarthria, decreased left-sided hearing acuity, and left facial droop. He presented at this point for endovascular evaluation. The patient underwent successful revascularization with intravascular Wingspan stents (Boston Scientific, Natick, Massachusetts) in a delayed fashion (approximately 6 weeks after his initial stroke presentation). His neurological syndrome stabilized and began to improve slowly.
CONCLUSION: Patients with arterial occlusion should be evaluated acutely for potential revascularization. In the posterior circulation, clinical progression may supplant physiological imaging in the assessment of hemodynamic collapse. A subpopulation of patients will present with progressive deficits distinct from extracranial manifestations of vertebrobasilar insufficiency; these patients should be considered for delayed revascularization.

SURGERY; SERIES; RESTORATION
AB BACKGROUND AND IMPORTANCE: The main therapeutic approach for malignant peripheral nerve sheath tumors (MPNSTs) of the brachial plexus is wide local excision. Sacrifice of some-occasionally all-elements of the brachial plexus often is required to obtain complete resection, and therefore can be associated with significant morbidity. While peripheral nerve repair is commonly used in the setting of traumatic nerve injury, little is known about its potential use in the treatment of MPNST.
CLINICAL PRESENTATION: We present a patient with an enlarging right neck mass who was diagnosed with MPNST of the brachial plexus. The patient underwent gross total resection of the tumor, requiring sectioning of the upper trunk of the brachial plexus, as well as associated divisions. Following resection, sural nerve grafts were used to connect the C5 nerve root to the anterior division of the upper trunk and the spinal accessory nerve to the suprascapular nerve, whereas a triceps branch of the radial nerve was coapted directly to the anterior division of the axillary nerve.
CONCLUSION: By 20 months after surgery, the patient had regained significant strength in her upper trunk distribution and demonstrated no evidence of tumor recurrence. Brachial plexus reconstruction offers a potentially valuable surgical adjunct to MPNST treatment.

ID CLINICALLY IMPORTANT DIFFERENCES; QUALITY-OF-LIFE; RHEUMATOID-ARTHRITIS;
IMPORTANT DIFFERENCE; DEFINITION
AB Objective To assess validity of pain and patient global scales in gout.
Methods The authors used data from pegloticase clinical trials in chronic refractory gout to examine the validity of visual analogue scale (VAS) pain, Short-Form 36 (SF-36) bodily pain subscale and VAS patient global assessment (all scales 0-100). Convergent/divergent validity with clinical characteristics was tested by using Spearman's correlation coefficient. For discriminant ability, the authors compared the change at 6 months between placebo and pegloticase arms and calculated effect size (ES) and standardised response mean (SRM).
Results 212 patients (mean age, 55.4 years, 82% men; 73% with tophaceous gout) provided data. VAS pain was statistically significantly correlated with tender joints (r = 0.42), swollen joints (r = 0.30), SF-36 physical (r = -0.56) and Mental Component Summary (r = -0.36) and Health Assessment Questionnaire scores (r = 0.54; all p-values <0.0001), but not disease duration (r = -0.01; p = 0.84), gout flares (r = 0.12; p = 0.08), comorbidities (r = 0.05; p = 0.47) or plasma urate (r = 0.01; p = 0.89). Similar and significant correlation coefficients with tender and swollen joints were noted for VAS patient global assessment (r = 0.35 and 0.23; p<0.0012 for both) and SF-36 pain subscale (r = -0.27 and -0.19; p<0.006 for both). Pegloticase group had significantly more improvement than placebo at 6 months, mean (SD): VAS pain, -9.2 (29.3) versus 1.9 (26.4), p = 0.0002; SF-36 pain, 14.6 (25.6) versus -0.04 (21.1), p<0.0001; and patient global, -9.3 (26.5) versus 3.4 (22.8), p<0.0001. ES and SRMs in pegloticase group were as follows: VAS pain, 0.34 and 0.30; SF-36 pain, 0.69 and 0.57; patient global, 0.49 and 0.44.
Conclusion VAS pain, SF-36 pain and patient global VAS are valid outcome measures in patients with chronic gout.

AB Purpose of review
The link between attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUDs) continues to be an area of great interest. In this report more recent work exploring the developmental relationship between ADHD and SUDs and associated concurrent disorders is discussed.
Recent findings
Recent work highlights the role of treatment of ADHD in children on subsequent cigarette smoking and SUDs in adolescence and adulthood. Contemporary data suggest that ADHD may be underdiagnosed in SUD populations. Studies in patients with ADHD and SUDs suggest that SUDs treatment needs to be sequenced initially with ADHD treatment quickly thereafter. Recent studies also highlight concerns associated with the misuse and diversion of prescription stimulants in ADHD adolescents and young adults and indicate that extended-release stimulants may reduce the likelihood for abuse.
Summary
Practitioners are increasingly recognizing the overlap between ADHD and SUDs, and treatment modalities including cognitive behavioral therapy and pharmacotherapy demonstrate mixed results in the treatment of these comorbid disorders. Areas in need of further investigation include the mechanism(s) by which ADHD leads to SUDs, diagnostic criteria associated with ADHD in SUD individuals, and prevention and treatment strategies for these populations.

TI Using electronic medical records to determine the diagnosis of clinical

AB Objective: To investigate the validity of using electronic medical records (EMR) database in a large health organization for identifying patients with clinical depression.
Method: The Massachusetts General Hospital EMR system was used to generate a sample of primary care patients seen in the primary care clinic in 2007. Using this sample, the validity of using certain fields in the EMR database (i.e., billing diagnosis, problem list, and medication list) to identify patients with clinical depression was compared to primary care physician (PCP) assessment by a written questionnaire. Based on this standard, the sensitivity, specificity, positive predictive value, negative predictive value, and the areas under receiver operating characteristic curve (AUC) of three specific EMR fields - individually and in combination - were calculated to identify which EMR field best predicted PCP classification.
Results: The EMR fields "billing diagnosis", "problem list" and antidepressant in "medication list", were all able to identify patients' diagnosis of depression by their PCPs reasonably well. Having one or more "billing diagnosis" of depression had the highest sensitivity and highest AUC (77% sensitivity, 76% specificity, AUC 0.77) among any of the fields used alone.
Conclusion: The AUC for "billing diagnosis" of depression performed the best of the three single fields tested, with an AUC of 0.77, corresponding to a test with moderate accuracy. This analysis demonstrates that specific EMR fields can be used as a proxy for PCP assessment of depression for this EMR system. Limitations to our analysis include the physician response rate to our survey as well as the quality of the data, which is collected primarily for administrative and clinical purposes. When using administrative and clinical data in mental health studies, researchers must first assess the accuracy of choosing specific fields within their EMR system in order to determine the level of accuracy for them to be used as proxies for clinical diagnoses.

AB The unpredictable nature of peptide binding to surfaces requires optimization of experimental containers to be used. To demonstrate the variable recoveries of peptides from multiple surfaces commonly employed in peptide research, we tested the recovery of radiolabeled 125I endocrine peptides under different conditions and provide guidelines for determining the surfaces to use for other peptides. (125)I-labeled peptides (ghrelin, sulfated cholecystokinin-8, corticotropin-releasing factor, glucagon-like peptide-1 [GLP-1], insulin, leptin, nesfatin-1, and peptide YY), representing a wide spectrum in net charge, size, end group, and modification, were incubated for 48 h in glass and plastic tubes untreated or coated with siliconizing fluid. Best surfaces were chosen and peptides were incubated with bovine serum albumin (BSA, 1%) with or without subsequent lyophilization. Recovery of (125)I-labeled peptides was determined by gamma counting. Important differences in (125)I-labeled peptide binding capacities to various types of surfaces exist. Siliconization decreased, whereas the addition of BSA improved recovery from surfaces tested. Lyophilizing solutions containing (125)I-labeled peptides and BSA in the tubes best suited for individual peptides rendered more than 89% recovery for all peptides. Ghrelin specifically displaced (125)I-ghrelin from borosilicate glass, whereas GLP-1 and Fmoc-arginine did not. Choosing the appropriate experimental container avoids unpredictable peptide loss that results in inaccurate measurements and false conclusions. (C) 2011 Elsevier Inc. All rights reserved.

AB CyrA is a novel cysteine-rich protein with four EGFL repeats that was isolated using the calmodulin (CaM) binding overlay technique (CaMBOT), suggesting it is a CaM-binding protein (CaMBP). The full-length 63 kDa cyrA is cleaved into two major C-terminal fragments, cyrA-C45 and cyrA-C40. A putative CaM-binding domain was detected and both CaM-agarose binding and CaM immunoprecipitation verified that cyrA-C45 and cyrA-C40 each bind to CaM in both a Ca(2+)-dependent and -independent manner. cyrA-C45 was present continuously throughout growth and development but was secreted at high levels during the multicellular slug stage of Dictyostelium development. At this time, cyrA localizes to the extracellular matrix (ECM). ECM purification verified the presence of cyrA-C45. An 18 amino acid peptide (DdEGFL1) from the first EGFL repeat sequence of cyrA (EGFL1) that is present in both cyrA-C45 and -C40 enhances both random cell motility and cAMP-mediated chemotaxis. Here we reveal that the dose-dependent enhancement of motility by DdEGFL1 is related to the time of cell starvation. Addition of DdEGFL1 also inhibits cyrA proteolysis. The status of cyrA as an extracellular CaMBP was further clarified by the demonstration that CaM is secreted during development. Antagonism of CaM with W7 resulted in enhanced cyrA proteolysis suggesting a functional role for extracellular CaM in protecting CaMBPs from proteolysis. cyrA is the first extracellular CaMBP identified in Dictyostelium and since it is an ECM protein with EGF-like repeats that enhance cell motility and it likely also represents the first matricellular protein identified in a lower eukaryote.

AB The use of cisplatin, a first line chemotherapy for most cancers, is dose-limited due to nephrotoxicity. While this toxicity can be addressed through nanotechnology, previous attempts at engineering cisplatin nanoparticles have been limited by the impact on the potency of cisplatin. Here we report the rational engineering of a novel cisplatin nanoparticle by harnessing a novel polyethylene glycol-functionalized poly-isobutylene-maleic acid (PEG-PIMA) copolymer, which can complex with cis-platinum (II) through a monocarboxylato and a coordinate bond. We show that this complex self-assembles into a nanoparticle, and exhibits an IC(50) = 0.77 +/- 0.11 mu M comparable to that of free cisplatin (IC(5)0 = 0.44 +/- 0.09 mu M). The nanoparticles are internalized into the endolysosomal compartment of cancer cells, and release cisplatin in a pH-dependent manner. Furthermore, the nanoparticles exhibit significantly improved antitumor efficacy in a 4T1 breast cancer model in vivo, with limited nephrotoxicity, which can be explained by preferential biodistribution in the tumor with reduced kidney concentrations. Our results suggest that the PEG-PIMA-cisplatin nanoparticle can emerge as an attractive solution to the challenges in cisplatin chemotherapy.

AB Methamphetamine (MA) dependence causes serious cognitive impairments that can persist during abstinence and negatively affect recovery outcomes. Evidence suggests that immune factors, such as cytokines, chemokines, and cellular adhesion molecules, contribute to MA-induced immune dysfunction, neuronal injury, and persistent cognitive impairments, yet the role of MA-induced brain inflammation remains unclear. To address this question, we used a cross-species, translational approach. Thirty-two male C57BL/6J mice were administered MA (1 mg/kg) or saline subcutaneously for seven consecutive days. Mice were euthanized at 72 h or 3 weeks after the last drug dose, and blood and brain samples were collected. In addition, 20 adults in remission from MA dependence and 20 non-dependent controls completed neuropsychological assessments and a blood draw. Multiplex assays were used to measure cytokine, chemokine, and intercellular adhesion molecule (ICAM-1) expression in mouse and human samples. A number of significant MA-induced changes in neuroimmune factors were observed. Of particular interest were the chemokine monocyte chemoattractant protein 1 (MCP-1) and the cellular adhesion molecule ICAM-1, which were similarly increased in the plasma of MA exposed mice as well as humans. In human participants, MA-induced changes in the cytokine and chemokine milieu were accompanied by increased cognitive impairments. Mice showing MA-induced changes in peripheral immune molecule expression also had significant brain-region specific changes in pro-inflammatory cytokines, chemokines, and ICAM-1. This cross-species, translational study suggests that chronic CNS immune dysregulation may in part contribute to the longlasting neuropsychiatric consequences of MA dependence.

AB The relationship between financial performance and quality of care in nursing homes is not well defined and prior work has been mixed. The recent focus on improving the quality of nursing homes through market-based incentives such as public reporting may have changed this relationship, as public reporting provides nursing homes with increased incentives to engage in quality-based competition. If quality improvement activities require substantial production costs, nursing home profitability may become a more important predictor of quality under public reporting. This study explores the relationship between financial performance and quality of care and test whether this relationship changes under public reporting. Using a 10-year (fiscal years 1997-2006) panel data set of 9444 skilled nursing facilities in the US, this study employs a facility fixed-effects with and without instrumental variables approach to test the effect of finances on quality improvement and correct for potential endogeneity. The results show that better financial performance, as reflected by the 1-year lagged total profit margin, is modestly associated with higher quality but only after public reporting is initiated. These findings have important policy implications as federal and state governments use market-based incentives to increase demand for high-quality care and induce providers to compete based on quality.

AB Background. I-123-metaiodobenzylguanidine (MIBG) scans are preferable to I-131-MIBG for neuroblastoma imaging as they deliver less patient radiation yet have greater sensitivity in disease detection. Both I-123-MIBG and I-131-MIBGscans were used for disease assessments of neuroblastoma patients enrolled on Children's Oncology Group (COG) high-risk study A3973. The hypothesis was that I-123-MIBG and I-131-MIBGscans were sufficiently similar for clinical purposes in terms of ability to predict survival. Procedure. Patients enrolled on COG A3973 with stage 4 disease who completed I-123-MIBG or I-131-MIBGscans at diagnosis, post-induction, posttransplant, or post-biotherapy were analyzed. The performance of the Curie score for each MIBG scan type in predicting survival was evaluated. At each time point, survival curves for I-123-MIBG versus I-131-MIBGwere compared using the log-rank test. Results. Of the 413 patients on A3973 with at least one MIBG scan, 350 were stage 4. The 5-year event-free survival (EFS) and overall survival (OS) rates were 33.4 +/- 3.6% and 45.6 +/- 4.0% (N = 350). At post-induction, EFS (P = 0.3501) and OS (P = 0.5337) for I-123-MIBG versus I-131-MIBGwere not significantly different. Similarly, comparisons at the three other time points were non-significant. Conclusions. We found no evidence of a statistically significant difference in outcome by type of scan. For future survival analyses of MIBG Curie scores, I-123-MIBG and I-131-MIBGresults may be combined and analyzed overall, without adjustment for scan type. Pediatr Blood Cancer 2011; 56: 1041-1045.

AB Purpose. To review our institution's experience with treatment of craniopharyngioma in children, and to report long-term treatment outcomes stratified by treatment era to assess whether modern treatment techniques result in improvements in local control and survival. Materials and Methods. We retrospectively reviewed the records of 100 children who underwent surgery for craniopharygioma at Children's Hospital Boston (CHB) from August 1976 to March 2003. Of these, 79 children (median age 8.5 years) had initial treatment at CHB and sufficient follow-up data to be included in this analysis. We report their treatment course, recurrence rates, and treatment-related morbidity. We compared the results in two different treatment eras based on changes in surgical approach at CHB. Results. Thirty-six patients underwent initial treatment with surgery alone; 63% treated prior to 1988 recurred and 36% treated after 1988 recurred. Recurrence rates following combined modality therapy (CMT) with limited surgery followed by radiation were 21 and 5% in the pre- and post-1988 eras, respectively. Accounting for treatment era, patients treated with surgery alone were 7.7 times as likely to recur as those treated with CMT (95% CI: 2.0, 28.7). In the Cox regression model, there was no significant difference in local control or overall survival based on treatment era; initial treatment remained the only statistically significant variable (P = 0.02). Conclusions. Advancements in treatment techniques have improved local control in children diagnosed with craniopharyngioma. The excellent survival rates necessitate long-term patient follow-up to identify and manage any treatment-related effects, including second tumors, vascular abnormalities, and endocrinopathies.

AB Contrary to the extensive amount of empirical findings about parental perceptions, parenting cognitions, and coping in families with a child with autism spectrum disorder (ASD), research about parenting itself is very scarce. A first goal of this study was to examine the factor structure and internal consistency of two scales to measure parenting behaviour: the Parental Behaviour Scale-short version (PBS, Van Leeuwen, 2002; Van Leeuwen & Vermulst, 2004, 2010) and a new scale to measure parenting behaviours more specifically relevant to children with ASD. A second goal was to compare general and more specific parenting behaviour among parents of children with and without ASD. The participants were 305 parents of a child with ASD between 8 and 18 years old and 325 parents of a typically developing child between 8 and 18 years old. Parents completed both scales. Exploratory factor analysis of the new scale resulted in two factors: Stimulating the Development and Adapting the Environment. Multisample confirmatory factor analyses showed good fit indices for the noninvariant model of both the PBS and the new scale. Mean level analyses revealed significant main effects of group with higher mean scores for the control group in comparison with the experimental group for the subscale Harsh Punishment and the reversed effect for the subscale Stimulating the Development. We concluded that it is possible to use the parenting constructs of the PBS-short version to investigate parenting behaviour of parents with and without children with ASD. Furthermore, the new scale showed a relatively stable two factor structure for the control group as well as for the experimental group. The two factors 'Stimulating the child's Development' and 'Adapting the child's Environment' were also convincing as regards content. A first indication was found that parents of children with ASD indeed use more specifically relevant parenting behaviours. It is self-evident that more research is needed to gain further insight into the nature of these behaviours. (C) 2011 Elsevier Ltd. All rights reserved.

AB A catalogue of molecular aberrations that cause ovarian cancer is critical for developing and deploying therapies that will improve patients' lives. The Cancer Genome Atlas project has analysed messenger RNA expression, microRNA expression, promoter methylation and DNA copy number in 489 high-grade serous ovarian adenocarcinomas and the DNA sequences of exons from coding genes in 316 of these tumours. Here we report that high-grade serous ovarian cancer is characterized by TP53 mutations in almost all tumours (96%); low prevalence but statistically recurrent somatic mutations in nine further genes including NF1, BRCA1, BRCA2, RB1 and CDK12; 113 significant focal DNA copy number aberrations; and promoter methylation events involving 168 genes. Analyses delineated four ovarian cancer transcriptional subtypes, three microRNA subtypes, four promoter methylation subtypes and a transcriptional signature associated with survival duration, and shed new light on the impact that tumours with BRCA1/2 (BRCA1 or BRCA2) and CCNE1 aberrations have on survival. Pathway analyses suggested that homologous recombination is defective in about half of the tumours analysed, and that NOTCH and FOXM1 signalling are involved in serous ovarian cancer pathophysiology.

TI Latent TGF-beta binding protein 3 identifies a second heart field in
zebrafish
SO NATURE

ID ARTERIAL POLE; OUTFLOW TRACT; MOUSE HEART; CELLS; GROWTH;
DIFFERENTIATION; ORIGIN
AB The four-chambered mammalian heart develops from two fields of cardiac progenitor cells distinguished by their spatiotemporal patterns of differentiation and contributions to the definitive heart(1-3). The first heart field differentiates earlier in lateral plate mesoderm, generates the linear heart tube and ultimately gives rise to the left ventricle. The second heart field (SHF) differentiates later in pharyngeal mesoderm, elongates the heart tube, and gives rise to the outflow tract and much of the right ventricle. Because hearts in lower vertebrates contain a rudimentary outflow tract but not a right ventricle(4), the existence and function of SHF-like cells in these species has remained a topic of speculation(4-10). Here we provide direct evidence from Cre/Lox-mediated lineage tracing and loss-of-function studies in zebrafish, a lower vertebrate with a single ventricle, that latent TGF-beta binding protein 3 (ltbp3) transcripts mark a field of cardiac progenitor cells with defining characteristics of the anterior SHF in mammals. Specifically, ltbp3(+) cells differentiate in pharyngeal mesoderm after formation of the heart tube, elongate the heart tube at the outflow pole, and give rise to three cardiovascular lineages in the outflow tract and myocardium in the distal ventricle. In addition to expressing Ltbp3, a protein that regulates the bioavailability of TGF-beta ligands(11), zebrafish SHF cells co-express nkx2.5, an evolutionarily conserved marker of cardiac progenitor cells in both fields(4). Embryos devoid of ltbp3 lack the same cardiac structures derived from ltbp3(+) cells due to compromised progenitor proliferation. Furthermore, small-molecule inhibition of TGF-beta signalling phenocopies the ltbp3-morphant phenotype whereas expression of a constitutively active TGF-beta type I receptor rescues it. Taken together, our findings uncover a requirement for ltbp3-TGF-beta signalling during zebrafish SHF development, a process that serves to enlarge the single ventricular chamber in this species.

AB Although police officers are frequently exposed to potentially traumatic incidents. only a minority will develop chronic posttraumatic stress disorder (FTSD). Identifying and understanding protective factors could inform the development of preventive interventions; however, few studies have examined this. In the present prospective study, 233 police officers were assessed during academy training and again following 2 years of police service. Caucasian race, less previous trauma exposure, and less critical incident exposure during police service as well as greater sense of self-worth, beliefs of greater benevolence of the world, greater social support and better social adjustment, all assessed during academy training, were associated with lower PTSD symptoms after 2 years of service. Positive personality attributes assessed during training with the NEO Five-Factor Personality Inventory were not associated with lower PTSD symptoms. In a hierarchical linear regression model, only Caucasian race, lower critical incident exposure during police service, greater assumptions of benevolence of the world and better social adjustment during training remained predictive of lower PTSD symptoms after 2 years of police service. These results suggest that positive world assumptions and better social functioning during training may protect police officers from critical incident related PTSD. (C) 2010 Elsevier Ireland Ltd.

AB Langerhans cells (LCs) are a distinct population of dendritic cells that form a contiguous network in the epidermis of the skin. Although LCs possess many of the properties of highly proficient dendritic cells, recent studies have indicated that they are not necessary to initiate cutaneous immunity. In this study, we used a tractable model of cutaneous GVHD, induced by topical application of a Toll-like receptor agonist, to explore the role of LCs in the development of tissue injury. By adapting this model to permit inducible and selective depletion of host LCs, we found that GVHD was significantly reduced when LCs were absent. However, LCs were not required either for CD8 T-cell activation within the draining lymph node or subsequent homing of effector cells to the epidermis. Instead, we found that LCs were necessary for inducing transcription of IFN-gamma and other key effector molecules by donor CD8 cells in the epidermis, indicating that they license CD8 cells to induce epithelial injury. These data demonstrate a novel regulatory role for epidermal LCs during the effector phase of an inflammatory immune response in the skin. (Blood. 2011;117(26):7063-7069)

AB The Lunenburg Lymphoma Biomarker Consortium (LLBC) evaluated the prognostic value of IHC biomarkers in a large series of patients with diffuse large B-cell lymphoma (DLBCL). Clinical data and tumor samples were retrieved from 12 studies from Europe and North America, with patients treated before or after the rituximab era. Using tissue microarrays from 1514 patients, IHC for BCL2, BCL6, CD5, CD10, MUM1, Ki67, and HLA-DR was performed and scored according to previously validated protocols. Optimal cut points predicting overall survival of patients treated in the rituximab era could only be determined for CD5 (P = .003) and Ki67 (P = .02), whereas such cut points for BCL2, BCL6, HLA-DR, and MUM1 could only be defined in patients not receiving rituximab. A prognostic model for patients treated in the rituximab era identified 4 risk groups using BCL2, Ki67, and International Prognostic Index (IPI) with improved discrimination of low-risk patients. Newly recognized correlations between specific biomarkers and IPI highlight the importance of carefully controlling for clinical and biologic factors in prognostic models. These data demonstrate that the IPI remains the best available index in patients with DLBCL treated with rituximab and chemotherapy. (Blood. 2011;117(26):7070-7078)

OF-FUNCTION; GENE; RISK; NEOPLASMS; CANCERS; TET2; CBL
AB BACKGROUND
Myelodysplastic syndromes are clinically heterogeneous disorders characterized by clonal hematopoiesis, impaired differentiation, peripheral-blood cytopenias, and a risk of progression to acute myeloid leukemia. Somatic mutations may influence the clinical phenotype but are not included in current prognostic scoring systems.
METHODS
We used a combination of genomic approaches, including next-generation sequencing and mass spectrometry-based genotyping, to identify mutations in samples of bone marrow aspirate from 439 patients with myelodysplastic syndromes. We then examined whether the mutation status for each gene was associated with clinical variables, including specific cytopenias, the proportion of blasts, and overall survival.
RESULTS
We identified somatic mutations in 18 genes, including two, ETV6 and GNAS, that have not been reported to be mutated in patients with myelodysplastic syndromes. A total of 51% of all patients had at least one point mutation, including 52% of the patients with normal cytogenetics. Mutations in RUNX1, TP53, and NRAS were most strongly associated with severe thrombocytopenia (P < 0.001 for all comparisons) and an increased proportion of bone marrow blasts (P < 0.006 for all comparisons). In a multivariable Cox regression model, the presence of mutations in five genes retained independent prognostic significance: TP53 (hazard ratio for death from any cause, 2.48; 95% confidence interval [CI], 1.60 to 3.84), EZH2 (hazard ratio, 2.13; 95% CI, 1.36 to 3.33), ETV6 (hazard ratio, 2.04; 95% CI, 1.08 to 3.86), RUNX1 (hazard ratio, 1.47; 95% CI, 1.01 to 2.15), and ASXL1 (hazard ratio, 1.38; 95% CI, 1.00 to 1.89).
CONCLUSIONS
Somatic point mutations are common in myelodysplastic syndromes and are associated with specific clinical features. Mutations in TP53, EZH2, ETV6, RUNX1, and ASXL1 are predictors of poor overall survival in patients with myelodysplastic syndromes, independently of established risk factors.

AB BACKGROUND
Phase 1 and 2 clinical trials of the BRAF kinase inhibitor vemurafenib (PLX4032) have shown response rates of more than 50% in patients with metastatic melanoma with the BRAF V600E mutation.
METHODS
We conducted a phase 3 randomized clinical trial comparing vemurafenib with dacarbazine in 675 patients with previously untreated, metastatic melanoma with the BRAF V600E mutation. Patients were randomly assigned to receive either vemurafenib (960 mg orally twice daily) or dacarbazine (1000 mg per square meter of body-surface area intravenously every 3 weeks). Coprimary end points were rates of overall and progression-free survival. Secondary end points included the response rate, response duration, and safety. A final analysis was planned after 196 deaths and an interim analysis after 98 deaths.
RESULTS
At 6 months, overall survival was 84% (95% confidence interval [CI], 78 to 89) in the vemurafenib group and 64% (95% CI, 56 to 73) in the dacarbazine group. In the interim analysis for overall survival and final analysis for progression-free survival, vemurafenib was associated with a relative reduction of 63% in the risk of death and of 74% in the risk of either death or disease progression, as compared with dacarbazine (P < 0.001 for both comparisons). After review of the interim analysis by an independent data and safety monitoring board, crossover from dacarbazine to vemurafenib was recommended. Response rates were 48% for vemurafenib and 5% for dacarbazine. Common adverse events associated with vemurafenib were arthralgia, rash, fatigue, alopecia, keratoacanthoma or squamous-cell carcinoma, photosensitivity, nausea, and diarrhea; 38% of patients required dose modification because of toxic effects.
CONCLUSIONS
Vemurafenib produced improved rates of overall and progression-free survival in patients with previously untreated melanoma with the BRAF V600E mutation. (Funded by Hoffmann-La Roche; BRIM-3 ClinicalTrials.gov number, NCT01006980.)

REDUCTION; WEIGHT
AB Background: Elevated triglyceride levels are a risk factor for cardiovascular disease. Angiopoietin-like protein 4 (Angptl4) is a metabolic factor that raises plasma triglyceride levels by inhibiting lipoprotein lipase (LPL). In nondiabetic individuals, the ANGPTL4 coding variant E40K has been associated with lower plasma triglyceride levels while the T266M variant has been associated with more modest effects on triglyceride metabolism. The objective of this study was to determine whether ANGPTL4 E40K and T266M are associated with triglyceride levels in the setting of obesity and T2D, and whether modification of triglyceride levels by these genetic variants is altered by a lifestyle intervention designed to treat T2D.
Methods: The association of ANGPTL4 E40K and T266M with fasting triglyceride levels was investigated in 2,601 participants from the Look AHEAD Clinical Trial, all of whom had T2D and were at least overweight. Further, we tested for an interaction between genotype and treatment effects on triglyceride levels.
Results: Among non-Hispanic White Look AHEAD participants, ANGPTL4 K40 carriers had mean triglyceride levels of 1.61 +/- 0.62 mmol/L, 0.33 mmol/L lower than E40 homozygotes (p = 0.001). Individuals homozygous for the minor M266 allele (MAF 30%) had triglyceride levels of 1.75 +/- 0.58 mmol/L, 0.24 mmol/L lower than T266 homozygotes (p = 0.002). The association of the M266 with triglycerides remained significant even after removing K40 carriers from the analysis (p = 0.002). There was no interaction between the weight loss intervention and genotype on triglyceride levels.
Conclusions: This is the first study to demonstrate that the ANGPTL4 E40K and T266M variants are associated with lower triglyceride levels in the setting of T2D. In addition, our findings demonstrate that ANGPTL4 genotype status does not alter triglyceride response to a lifestyle intervention in the Look AHEAD study.

AB Hutchinson-Gilford progeria syndrome (HGPS) is a lethal genetic disorder characterized by premature aging. HGPS is most commonly caused by a de novo single-nucleotide substitution in the lamin A/C gene (LMNA) that partially activates a cryptic splice donor site in exon 11, producing an abnormal lamin A protein termed progerin. Accumulation of progerin in dividing cells adversely affects the integrity of the nuclear scaffold and leads to nuclear blebbing in cultured cells. Progerin is also produced in normal cells, increasing in abundance as senescence approaches. Here, we report the effect of rapamycin, a macrolide antibiotic that has been implicated in slowing cellular and organismal aging, on the cellular phenotypes of HGPS fibroblasts. Treatment with rapamycin abolished nuclear blebbing, delayed the onset of cellular senescence, and enhanced the degradation of progerin in HGPS cells. Rapamycin also decreased the formation of insoluble progerin aggregates and induced clearance through autophagic mechanisms in normal fibroblasts. Our findings suggest an additional mechanism for the beneficial effects of rapamycin on longevity and encourage the hypothesis that rapamycin treatment could provide clinical benefit for children with HGPS.

AB The peroxisome-proliferator-activated receptor gamma coactivator 1 alpha (PGC1 alpha) has been implicated in the pathogenesis of several neurodegenerative disorders, including Huntington's disease (HD). Recent data demonstrating white matter abnormalities in PGC1 alpha knock-out (KO) mice prompted us to examine the role of PGC1 alpha in CNS myelination and its relevance to HD pathogenesis. We found deficient postnatal myelination in the striatum of PGC1 alpha KO mice, accompanied by a decrease in myelin basic protein (MBP). In addition, brain cholesterol, its precursors, and the rate-limiting enzymes for cholesterol synthesis, HMG CoA synthase (HMGCS1) and HMG CoA reductase (HMGCR), were also reduced in PGC1 alpha KO mice. Moreover, knockdown of PGC1 alpha in oligodendrocytes by lentiviral shRNA led to a decrease in MBP, HMGCS1, and Hmgcr mRNAs. Chromatin immunoprecipitations revealed the recruitment of PGC1 alpha to MBP promoter in mouse brain, and PGC1 alpha over-expression increased MBP and SREBP-2 promoter activity, suggesting that PGC1 alpha regulates MBP and cholesterol synthesis at the transcriptional level. Importantly, expression of mutant huntingtin (Htt) in primary oligodendrocytes resulted in decreased expression of PGC1 alpha and its targets HmgcS1, Hmgcr, and MBP. Decreased expression of MBP and deficient myelination were found postnatally and in adult R6/2 mouse model of HD. Diffusion tensor imaging detected white matter abnormalities in the corpus callosum of R6/2 mice, and electron microscopy revealed thinner myelin sheaths and increased myelin periodicity in BACHD [bacterial artificial chromosome (BAC)-mediated transgenic model for Huntington's disease] mice expressing full-length mutant Htt. Together, these data suggest that PGC1 alpha plays a role in postnatal myelination and that deficient PGC1 alpha activity in oligodendrocytes may contribute to abnormal myelination in HD.

TI A New System for the Rapid Collection of Large Numbers of
Developmentally Staged Zebrafish Embryos
SO PLOS ONE

DT Article
ID DANIO-RERIO; VERTEBRATE; BEHAVIOR
AB The zebrafish is an excellent genetic and developmental model system used to study biology and disease. While the zebrafish model is associated with high fecundity, its reproductive potential has not been completely realized by scientists. One major issue is that embryo collection is inefficient. Here, we have developed an innovative breeding vessel designed to stimulate the natural reproductive behavior of the fish. This novel apparatus allows us to collect large numbers of developmentally synchronized embryos in brief and defined windows of time, and with minimal investments in labor and space. To demonstrate the efficacy of this approach, we placed three separate groups (n = 180) of fish in the vessel and allowed them to spawn for 10-minute intervals. During these trials, which were repeated three times, the fish produced 8600 +/- 917, 8400 +/- 794, and 6800 +/- 1997 embryos, respectively. This level of embryo production is nearly twice what we were able to achieve when using conventional crossing equipment with some of the same fish, and it required significantly less room and time to set up and break down. This system overcomes major space and labor restrictions inherent in spawning equipment currently used in the field, and will greatly accelerate efforts to improve the scale and throughput of experiments.

AB A prophylactic vaccine is needed to slow the spread of HIV-1 infection. Optimization of the wild-type envelope glycoproteins to create immunogens that can elicit effective neutralizing antibodies is a high priority. Starting with ten genes encoding subtype B HIV-1 gp120 envelope glycoproteins and using in vitro homologous DNA recombination, we created chimeric gp120 variants that were screened for their ability to bind neutralizing monoclonal antibodies. Hundreds of variants were identified with novel antigenic phenotypes that exhibit considerable sequence diversity. Immunization of rabbits with these gp120 variants demonstrated that the majority can induce neutralizing antibodies to HIV-1. One novel variant, called ST-008, induced significantly improved neutralizing antibody responses when assayed against a large panel of primary HIV-1 isolates. Further study of various deletion constructs of ST-008 showed that the enhanced immunogenicity results from a combination of effective DNA priming, an enhanced V3-based response, and an improved response to the constant backbone sequences.

TI Heterotopic Ossifications in a Mouse Model of Albright Hereditary
Osteodystrophy

AB Albright hereditary osteodystrophy (AHO) is characterized by short stature, brachydactyly, and often heterotopic ossifications that are typically subcutaneous. Subcutaneous ossifications (SCO) cause considerable morbidity in AHO with no effective treatment. AHO is caused by heterozygous inactivating mutations in those GNAS exons encoding the alpha-subunit of the stimulatory G protein (G alpha(s)). When inherited maternally, these mutations are associated with obesity, cognitive impairment, and resistance to certain hormones that mediate their actions through G protein-coupled receptors, a condition termed pseudohypoparathyroidism type 1a (PHP1a). When inherited paternally, GNAS mutations cause only AHO but not hormonal resistance, termed pseudopseudohypoparathyroidism (PPHP). Mice with targeted disruption of exon 1 of Gnas (Gnas(E1-/+)) replicate human PHP1a or PPHP phenotypically and hormonally. However, SCO have not yet been reported in Gnas(E1+/-) mice, at least not those that had been analyzed by us up to 3 months of age. Here we now show that Gnas(E1-/+) animals develop SCO over time. The ossified lesions increase in number and size and are uniformly detected in adult mice by one year of age. They are located in both the dermis, often in perifollicular areas, and the subcutis. These lesions are particularly prominent in skin prone to injury or pressure. The SCO comprise mature bone with evidence of mineral deposition and bone marrow elements. Superficial localization was confirmed by radiographic and computerized tomographic imaging. In situ hybridization of SCO lesions were positive for both osteonectin and osteopontin. Notably, the ossifications were much more extensive in males than females. Because Gnas(E1-/+) mice develop SCO features that are similar to those observed in AHO patients, these animals provide a model system suitable for investigating pathogenic mechanisms involved in SCO formation and for developing novel therapeutics for heterotopic bone formation. Moreover, these mice provide a model with which to investigate the regulatory mechanisms of bone formation.

AB Purpose: Aberrant microRNA (miRNA) expression is associated with cancer and has potential diagnostic and prognostic value in various malignancies. In this study, we investigated miRNA profiling as a complementary tool to improve our understanding of breast cancer (BC) biology and to assess whether miRNA expression could predict clinical outcome of BC patients.
Experimental Design: Global miRNA expression profiling using microarray technology was conducted in 56 systemically untreated BC patients who had corresponding mRNA expression profiles available. Results were further confirmed using qRT-PCR in an independent dataset of 89 ER-positive BC patients homogeneously treated with tamoxifen only. MiR-210 functional analyses were performed in MCF7 and MDA-MB-231 BC cell lines using lentiviral transduction.
Results: Estrogen receptor (ER) status, tumor grade and our previously developed gene expression grade index (GGI) were associated with distinct miRNA profiles. Several miRNAs were found to be clinically relevant, including miR-210, its expression being associated with tumor proliferation and differentiation. Furthermore, miR-210 was associated with poor clinical outcome in ER-positive, tamoxifen-treated BC patients. Interestingly, the prognostic performance of miR-210 was similar to several reported multi-gene signatures, highlighting its important role in BC differentiation and tumor progression. Functional analyses in BC cell lines revealed that miR-210 is involved in cell proliferation, migration and invasion.
Conclusions: This integrated analysis combining miRNA and mRNA expression demonstrates that miRNA expression provides additional biological information beyond mRNA expression. Expression of miR-210 is linked to tumor proliferation and appears to be a strong potential biomarker of clinical outcome in BC.

AB BACKGROUND: Circulating endothelial cells (CECs) are a candidate biomarker for monitoring angiogenesis in cancer. Circulating endothelial cell subsets are mobilised by angiogenic mediators. Because of the highly angiogenic phenotype of renal cell carcinoma (RCC), we sought to assess the potential of CECs as a marker of RCC in patients with von Hippel-Lindau (VHL) disease and those with sporadic RCC.
METHODS: We performed multicolour flow cytometry to enumerate CECs in patients with RCC, patients with VHL disease with and without RCC, and normal subjects. Two subsets of CECs were evaluated: mature CECs (mCECs) and circulating endothelial progenitors (CEPs).
RESULTS: In patients with VHL disease and RCC and those with sporadic RCC (N = 10), CEPs and the CEP:mCEC ratio were higher than in normal subjects (N = 17) (median CEPs: 0.97 vs 0.19 cells mu l(-1), respectively, P<0.01; median CEP:mCEC:0.92 vs 0.58, respectively, P = 0.04). However, in patients with VHL without RCC, CECs were not increased. In paired pre- and post-nephrectomy RCC patient samples (N = 20), CEPs decreased after surgery (median difference 0.02 cells mu l(-1), -0.06 to 1.2; P = 0.05).
CONCLUSION: Circulating endothelial progenitors were elevated in RCC, but not in patients with VHL without RCC. Circulating endothelial progenitor enumeration merits further investigation as a monitoring strategy for patients with VHL.

TI Increased risk of hepatocellular carcinoma after cholecystectomy
SO BRITISH JOURNAL OF CANCER
LA English
DT Article
DE liver cancer; gall bladder; epidemiology; risk
ID CANCER; LIVER
AB BACKGROUND: The association between gall bladder removal (cholecystectomy) and hepatocellular carcinoma warrants investigation. An increased intrahepatic bile duct pressure following cholecystectomy might cause chronic inflammation in the surrounding liver tissue, which might induce cancer development.
METHODS: A nationwide Swedish population-based cohort study in 1965-2008 included 345 251 patients undergoing cholecystectomy because of gallstone. The number of observed hepatocellular carcinoma cases was divided by the expected number, calculated from the corresponding background Swedish population, thus providing standardised incidence ratios (SIRs) with 95% confidence intervals (CIs).
RESULTS: During follow-up of 4 854 969 person-years, 333 new cases of hepatocellular carcinoma were identified, rendering an overall increased risk (SIR 1.24, 95% CI: 1.11-1.38). The risk increased with longer follow-up (P for trend = 0.003). Among patients who underwent cholecystectomy 30-43 years earlier, SIR was 2.00 (95% CI: 1.32-2.87). The results were similar after exclusion of 15 634 patients with any recorded risk factor, that is, diabetes, obesity, hepatitis, liver cirrhosis, alcoholism, or blood transfusion.
CONCLUSION: Cholecystectomy might be associated with a long-term increased risk of hepatocellular carcinoma. British Journal of Cancer (2011) 105, 154-156. doi:10.1038/bjc.2011.181 www.bjcancer.com Published online 24 May 2011 (C) 2011 Cancer Research UK

AB BACKGROUND: Carriers of germline mutations in DNA mismatch repair (MMR) genes have a high risk of colorectal cancer (CRC), but the modifiers of this risk are not well established. We estimated an association between body mass index (BMI) in early adulthood and subsequent risk of CRC for carriers and, as a comparison, estimated the association for non-carriers.
METHODS: A weighted Cox regression was used to analyse height and weight at 20 years reported by 1324 carriers of MMR gene mutations (500 MLH1, 648 MSH2, 117 MSH6 and 59 PMS2) and 1219 non-carriers from the Colon Cancer Family Registry.
RESULTS: During 122 304 person-years of observation, we observed diagnoses of CRC for 659 carriers (50%) and 36 non-carriers (3%). For carriers, the risk of CRC increased by 30% for each 5 kgm(-2) increment in BMI in early adulthood (hazard ratio, HR: 1.30; 95% confidence interval, CI: 1.08-1.58; P = 0.01), and increased by 64% for non-carriers (HR: 1.64; 95% CI: 1.02-2.64; P = 0.04) after adjusting for sex, country, cigarette smoking and alcohol drinking (and the MMR gene that was mutated in carriers). The difference in HRs for carriers and non-carriers was not statistically significant (P = 0.50). For MLH1 and PMS2 (MutL alpha heterodimer) mutation carriers combined, the corresponding increase was 36% (HR: 1.36; 95% CI: 1.05-1.76; P = 0.02). For MSH2 and MSH6 (MutS alpha heterodimer) mutation carriers combined, the HR was 1.26 (95% CI: 0.96-1.65; P = 0.09). There was no significant difference between the HRs for MutLa and MutSa heterodimer carriers (P = 0.56).
CONCLUSION: Body mass index in early adulthood is positively associated with risk of CRC for MMR gene mutation carriers and non-carriers. British Journal of Cancer (2011) 105, 162-169. doi:10.1038/bjc.2011.172 www.bjcancer.com Published online 10 May 2011 (C) 2011 Cancer Research UK

AB Background: Pseudoexfoliation (PXF) is a recognized risk factor for developing cataract, glaucoma and lens dislocation. PXF is also associated with increased risk of complications during cataract surgery due to poor mydriasis and zonular weakness. The aim of this study is to report the prevalence of pseudoexfoliation among Upper Egyptians attending the ophthalmology clinic of Assiut University Hospital.
Methodology: A retrospective, chart review study conducted in the period from February 2002 to August 2009. A total of 7738 patients aged 40 years or older attending the general ophthalmic clinics were included in this study. A detailed evaluation including ophthalmic and general history, slit lamp biomicroscopy, intraocular pressure measurement, gonioscopy and dilated eye examination were performed. Patients with pseudoexfoliative material on the anterior lens surface and/or the pupillary margin in either or both eyes were labeled as having PXF.
Results: Out of the 7738 patients included, three hundred twenty (4.14%) subjects had PXF. Mean age of PXF group was 68.15 years (SD 8.16, range 40-92 years). PXF was bilateral in 82.2% of cases. It was significantly associated with cataract, glaucoma and hearing loss. Of the PXF patients, 65% had cataract, 30.3% had glaucoma and 8.1% had hearing loss.
Conclusion: Pseudoexfoliation appears to be a common disorder in older individuals in Upper Egypt.

AB Relatively little is known about the time course of the development of spontaneous recurrent seizures (i.e., epileptogenesis) after brain injury in human patients, or even in animal models. This time course is determined, at least in part, by the underlying molecular and cellular mechanisms responsible for acquired epilepsy. An understanding of the critical mechanistic features of acquired epilepsy will be useful, if not essential, for developing strategies to block or suppress epileptogenesis. Here, data on the time course of the development of spontaneous recurrent seizures are summarized from experiments using nearly continuous electrographic (EEG) recordings in (1) kainate-treated rats, which are a model of temporal lobe epilepsy, and (2) rats subjected to unilateral carotid occlusion with superimposed hypoxia at postnatal day 7, which is a model of perinatal stroke. Although the classical view of the development of epileptogenesis is a step-function of time after the brain injury, with a latent period present between the brain injury and the first unprovoked seizure, the data described here show that seizure frequency was a sigmoid function of time after the insult in both animal models. Furthermore, the spontaneous recurrent seizures often occurred in clusters, even shortly after the first spontaneous seizure. These data suggest that (1) epileptogenesis is a continuous process that extends past the first spontaneous clinical seizure, (2) seizure clusters can obscure this continuous process, and (3) the potential time for administration of a therapy to suppress acquired epilepsy extends well past the first clinical seizure.

AB Interictal spikes are brief paroxysmal electrographic discharges observed between spontaneous recurrent seizures in epileptic patients. The relationship between interictal spikes and the seizures that define acquired epilepsy has been debated for decades. Recent studies using long-term continuous electrographic recordings from the hippocampus and cortex in rats with kainate-induced epilepsy suggest that electrographic spikes, with waveforms similar to interictal spikes, precede the occurrence of the first spontaneous epileptic seizure. These data raise the possibility that spikes might serve as a surrogate marker of ongoing chronic epileptogenesis. Additionally, electrographic spikes might actually contribute to the development and maintenance of the epileptic state (i.e., the increased probability of spontaneous recurrent seizures). Correlational evidence for such a causal relationship has recently also been obtained in an in vitro model of epileptogenesis using organotypic hippocampal slices. Testing for a causal relationship will ultimately require selective anti-spike medications. Although no such agents currently exist, this new preparation is amenable to moderate-throughput screening, which should accelerate their discovery. Anti-spike agents may also be of benefit in ameliorating the cognitive dysfunctions associated with epilepsy, to which spike activity may contribute. (C) 2011 Elsevier Ireland Ltd.

AB The principal constituent of the living cell is water. The role of the hydration shell and bulk H2O solvent is well recognized in the dynamics of isolated proteins, but the role of water in the dynamics of the integrated living cytoskeleton (CSK) remains obscure. Here we report a direct connection of dynamics of water to dynamics of the integrated CSK. The latter are known to be scale-free and to hinge upon a frequency f(0) that is roughly invariant across cell types. Although f(0) is comparable in magnitude to the rotational relaxation frequency of water (gigahertz range), the physical basis of f(0) remains unknown. Using the human airway smooth muscle cell as a model system, we show here that replacing water acutely with deuterium oxide impacts CSK dynamics in major ways, slowing CSK remodeling dynamics appreciably, and lowering f(0) by up to four orders of magnitude. Although these observations do not distinguish contributions of bulk solvent versus hydration shell, they suggest a unifying hypothesis, namely, that dynamics of integrated CSK networks are slaved in a direct fashion to fluctuations arising in intracellular water.

AB The HIV-1 envelope glycoprotein (Env) spike is challenging to study at the molecular level, due in part to its genetic variability, structural heterogeneity and lability. However, the extent of lability in Env function, particularly for primary isolates across clades, has not been explored. Here, we probe stability of function for variant Envs of a range of isolates from chronic and acute infection, and from clades A, B and C, all on a constant virus backbone. Stability is elucidated in terms of the sensitivity of isolate infectivity to destabilizing conditions. A heat-gradient assay was used to determine T(90) values, the temperature at which HIV-1 infectivity is decreased by 90% in 1 h, which ranged between similar to 40 to 49 degrees C (n = 34). For select Envs (n = 10), the half-lives of infectivity decay at 37 degrees C were also determined and these correlated significantly with the T90 (p = 0.029), though two 'outliers' were identified. Specificity in functional Env stability was also evident. For example, Env variant HIV-1(ADA) was found to be labile to heat, 37 degrees C decay, and guanidinium hydrochloride but not to urea or extremes of pH, when compared to its thermostable counterpart, HIV-1(JR-CSF). Blue native PAGE analyses revealed that Env-dependent viral inactivation preceded complete dissociation of Env trimers. The viral membrane and membrane-proximal external region (MPER) of gp41 were also shown to be important for maintaining trimer stability at physiological temperature. Overall, our results indicate that primary HIV-1 Envs can have diverse sensitivities to functional inactivation in vitro, including at physiological temperature, and suggest that parameters of functional Env stability may be helpful in the study and optimization of native Env mimetics and vaccines.

AB Background: One-carbon metabolism appears to play an important role in DNA methylation reaction. Evidence suggests that a low intake of B vitamins or high alcohol consumption increases colorectal cancer risk. How one-carbon nutrients affect the CpG island methylator phenotype (CIMP) or BRAF mutation status in colon cancer remains uncertain.
Methods: Utilizing incident colon cancers in a large prospective cohort of women (the Nurses' Health Study), we determined BRAF status (N = 386) and CIMP status (N = 375) by 8 CIMP-specific markers [CACNA1G, CDKN2A (p16), CRABP1, IGF2, MLH1, NEUROG1, RUNX3, and SOCS1], and 8 other CpG islands (CHFR, HIC1, IGFBP3, MGMT, MINT-1, MINT-31, p14, and WRN). We examined the relationship between intake of one-carbon nutrients and alcohol and colon cancer risk, by BRAF mutation or CIMP status.
Results: Higher folate intake was associated with a trend towards low risk of CIMP-low/0 tumors [ total folate intake >= 400 mg/day vs. <200 mu g/day; the multivariate relative risk = 0.73; 95% CI = 0.53-1.02], whereas total folate intake had no influence on CIMP-high tumor risks (P-heterogeneity = 0.73). Neither vitamin B-6, methionine or alcohol intake appeared to differentially influence risks for CIMP-high and CIMP-low/0 tumors. Using the 16-marker CIMP panel did not substantially alter our results. B vitamins, methionine or alcohol intake did not affect colon cancer risk differentially by BRAF status.
Conclusions: This molecular pathological epidemiology study suggests that low level intake of folate may be associated with an increased risk of CIMP-low/0 colon tumors, but not that of CIMP-high tumors. However, the difference between CIMP-high and CIMP-low/0 cancer risks was not statistically significant, and additional studies are necessary to confirm these observations.

AB Melanoma is the leading cause of death from skin disease due, in large part, to its propensity to metastasize. We have examined the effect of grape seed proanthocyanidins (GSPs) on melanoma cancer cell migration and the molecular mechanisms underlying these effects using highly metastasis-specific human melanoma cell lines, A375 and Hs294t. Using in vitro cell invasion assays, we observed that treatment of A375 and Hs294t cells with GSPs resulted in a concentration-dependent inhibition of invasion or cell migration of these cells, which was associated with a reduction in the levels of cyclooxygenase (COX)-2 expression and prostaglandin (PG) E-2 production. Treatment of cells with celecoxib, a COX-2 inhibitor, or transient transfection of melanoma cells with COX-2 small interfering RNA, also inhibited melanoma cell migration. Treatment of cells with 12-O-tetradecanoylphorbol-13-acetate, an inducer of COX-2, enhanced the phosphorylation of ERK1/2, a protein of mitogen-activated protein kinase family, and subsequently cell migration whereas both GSPs and celecoxib significantly inhibited 12-O-tetradecanoylphorbol-13-acetate - promoted cell migration as well as phosphorylation of ERK1/2. Treatment of cells with UO126, an inhibitor of MEK, also inhibited the migration of melanoma cells. Further, GSPs inhibited the activation of NF-kappa B/p65, an upstream regulator of COX-2, in melanoma cells, and treatment of cells with caffeic acid phenethyl ester, an inhibitor of NF-kappa B, also inhibited cell migration. Additionally, inhibition of melanoma cell migration by GSPs was associated with reversal of epithelial-mesenchymal transition process, which resulted in an increase in the levels of epithelial biomarkers (E-cadherin and cytokeratins) while loss of mesenchymal biomarkers (vimentin, fibronectin and N-cadherin) in melanoma cells. Together, these results indicate that GSPs have the ability to inhibit melanoma cell invasion/migration by targeting the endogenous expression of COX-2 and reversing the process of epithelial-to-mesenchymal transition.

AB T cell-dependent autoimmune diseases are characterized by the expansion of T cell clones that recognize immunodominant epitopes on the target antigen. As a consequence, for a given autoimmune disorder, pathogenic T cell clones express T cell receptors with a limited number of variable regions that define antigenic specificity. Qa-1, a MHC class I-like molecule, presents peptides from the variable region of TCRs to Qa-1-restricted CD8+ T cells. The induction of V beta-specific CD8+ T cells has been harnessed in an immunotherapeutic strategy known as the "T cell vaccination'' (TCV) that comprises the injection of activated and attenuated CD4+ T cell clones so as to induce protective CD8+ T cells. We hypothesized that Qa-1-restricted CD8+ regulatory T cells could also constitute a physiologic regulatory arm of lymphocyte responses upon expansion of endogenous CD4+ T cells, in the absence of deliberate exogenous T cell vaccination. We immunized mice with two types of antigenic challenges in order to sequentially expand antigen-specific endogenous CD4+ T cells with distinct antigenic specificities but characterized by a common V beta chain in their TCR. The first immunization was performed with a non-self antigen while the second challenge was performed with a myelin-derived peptide known to drive experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis. We show that regulatory V beta-specific Qa-1-restricted CD8+ T cells induced during the first endogenous CD4+ T cell responses are able to control the expansion of subsequently mobilized pathogenic autoreactive CD4+ T cells. In conclusion, apart from the immunotherapeutic TCV, Qa-1-restricted specialized CD8+ regulatory T cells can also be induced during endogenous CD4+ T cell responses. At variance with other regulatory T cell subsets, the action of these Qa-1-restricted T cells seems to be restricted to the immediate reactivation of CD4+ T cells.

AB Background. Transplant centers vary in the proportion of kidney transplants performed using live donors. Clinical innovations that facilitate live donation may drive this variation.
Methods. We assembled a cohort of renal transplant candidates at 194 US centers using registry data from 1999 to 2005. We measured magnitude of live donor kidney transplantation (LDKTx) through development of a standardized live donor transplantation ratio (SLDTR) at each center that accounted for center population differences. We examined associations between center characteristics and the likelihood that individual transplant candidates underwent LDKTx. To identify practices through which centers increase LDKTx, we also examined center characteristics associated with consistently being in the upper three quartiles of SLDTR.
Results. The cohort comprised 148,168 patients, among whom 34,593 (23.3%) underwent LDKTx. In multivariable logistic regression, candidates had an increased likelihood of undergoing LDKTx at centers with greater use of "unrelated donors" (defined as nonspouses and nonfirst-degree family members of the recipient; odds ratio [OR] 1.31 for highest vs. lowest use; P=0.02) and at centers with programs to overcome donor-recipient incompatibility (OR 1.33; P=0.01). Centers consistently in the upper three SLDTR quartiles were also more likely to use "unrelated" donors (OR 8.30 per tertile of higher use; P<0.01), to have incompatibility programs (OR 4.79, P<0.01), and to use laparoscopic nephrectomy (OR 2.53 per tertile of higher use; P=0.02).
Conclusion. Differences in center population do not fully account for differences in the use of LDKTx. To maximize opportunities for LDKTx, centers may accept more unrelated donors and adopt programs to overcome biological incompatibility.

DISEASE; DEATH
AB Background: Drug-eluting stents (DES) reduce rates of restenosis compared with bare metal stents (BMS). A number of observational studies have also found lower rates of mortality and non-fatal myocardial infarction with DES compared with BMS, findings not observed in randomized clinical trials. In order to explore reasons for this discrepancy, we compared outcomes after percutaneous coronary intervention (PCI) with DES or BMS by multiple statistical methods.
Methods: We compared short-term rates of all-cause mortality and myocardial infarction for patients undergoing PCI with DES or BMS using propensity-score adjustment, propensity-score matching, and a stent-era comparison in a large, integrated health system between 1998 and 2007. For the propensity-score adjustment and stent era comparisons, we used multivariable logistic regression to assess the association of stent type with outcomes. We used McNemar's Chi-square test to compare outcomes for propensity-score matching.
Results: Between 1998 and 2007, 35,438 PCIs with stenting were performed among health plan members (53.9% DES and 46.1% BMS). After propensity-score adjustment, DES was associated with significantly lower rates of death at 30 days (OR 0.49, 95% CI 0.39-0.63, P < 0.001) and one year (OR 0.58, 95% CI 0.49 - 0.68, P < 0.001), and a lower rate of myocardial infarction at one year (OR 0.72, 95% CI 0.59 - 0.87, P < 0.001). Thirty day and one year mortality were also lower with DES after propensity-score matching. However, a stent era comparison, which eliminates potential confounding by indication, showed no difference in death or myocardial infarction for DES and BMS, similar to results from randomized trials.
Conclusions: Although propensity-score methods suggested a mortality benefit with DES, consistent with prior observational studies, a stent era comparison failed to support this conclusion. Unobserved factors influencing stent selection in observational studies likely account for the observed mortality benefit of DES not seen in randomized clinical trials.

AB Hepatic stellate cells (HSC) store retinoids and upon activation differentiate into myofibroblast-like cells, a process whereby they lose their retinoid-containing lipid droplets. We reported earlier, activation of tissue factor (TF) in our MCT/LPS hepatotoxicity model. We now report the involvement of TF in the release of retinoid receptors RAR-alpha and RXR-alpha as accumulated lipid droplet during monocrotaline/lipopolysaccharide (MCT/LPS)-liver injury. Constitutive expression of RAR-alpha was observed in HSCs and endothelial cells of bile duct and portal vein, while expression of RXR-alpha was observed in certain pericentral hepatocytes and HSCs. Administration of sub-toxic doses of MCT or LPS strongly increased TF and RXR-alpha but not RAR-alpha expressions in HSCs and hepatocytes. However MCT/LPS co-treatment showed insoluble droplets containing RAR-alpha and RXR-alpha in the vicinity of the necrotic areas. Blocking TF with TF antisense oligonucleotides (TF-AS ODN) led to normal hepatocyte expression of RXR-alpha and upregulated the expression of RAR-alpha in HSCs. This study shows clear evidence of in vivo release of RAR-alpha and RXR-alpha as insoluble lipid droplets in liver injury. It is possible that these insoluble droplets of RAR-alpha and RXR-alpha could be used as markers for liver injury in general and activation of HSCs in particular. RXR-alpha appears to be a more sensitive than RAR-alpha as it was affected by even the subtoxic doses of MCT or LPS. The fact that IF-AS treatment not only down-regulated TF but also obliterated the release of RAR-alpha and RXR-alpha as insoluble lipid droplets in hepatocytes points towards TF being an important regulatory molecule for RAR-alpha and RXR-alpha.

AB Protein kinases are intensely studied mediators of cellular signaling, yet important questions remain regarding their regulation and in vivo properties. Here, we use a probe-based chemoprotemics platform to profile several well studied kinase inhibitors against >200 kinases in native cell proteomes and reveal biological targets for some of these inhibitors. Several striking differences were identified between native and recombinant kinase inhibitory profiles, in particular, for the Raf kinases. The native kinase binding profiles presented here closely mirror the cellular activity of these inhibitors, even when the inhibition profiles differ dramatically from recombinant assay results. Additionally, Raf activation events could be detected on live cell treatment with inhibitors. These studies highlight the complexities of protein kinase behavior in the cellular context and demonstrate that profiling with only recombinant/purified enzymes can be misleading.

TI The Small GTPase Cdc42 Is Necessary for Primary Ciliogenesis in Renal

AB Primary cilia are found on many epithelial cell types, including renal tubular epithelial cells, where they participate in flow sensing. Disruption of cilia function has been linked to the pathogenesis of polycystic kidney disease. We demonstrated previously that the exocyst, a highly conserved eight-protein membrane trafficking complex, localizes to primary cilia of renal tubular epithelial cells, is required for ciliogenesis, biochemically and genetically interacts with polycystin-2 (the protein product of the polycystic kidney disease 2 gene), and, when disrupted, results in MAPK pathway activation both in vitro and in vivo. The small GTPase Cdc42 is a candidate for regulation of the exocyst at the primary cilium. Here, we demonstrate that Cdc42 biochemically interacts with Sec10, a crucial component of the exocyst complex, and that Cdc42 colocalizes with Sec10 at the primary cilium. Expression of dominant negative Cdc42 and shRNA-mediated knockdown of both Cdc42 and Tuba, a Cdc42 guanine nucleotide exchange factor, inhibit ciliogenesis in Madin-Darby canine kidney cells. Furthermore, exocyst Sec8 and polycystin-2 no longer localize to primary cilia or the ciliary region following Cdc42 and Tuba knockdown. We also show that Sec10 directly interacts with Par6, a member of the Par complex that itself directly interacts with Cdc42. Finally, we show that Cdc42 knockdown results in activation of the MAPK pathway, something observed in cells with dysfunctional primary cilia. These data support a model in which Cdc42 localizes the exocyst to the primary cilium, whereupon the exocyst then targets and docks vesicles carrying proteins necessary for ciliogenesis.

AB Background: Clinical evolution of HIV-infected children who have not yet initiated antiretroviral treatment (ART) is poorly understood in Africa. We describe severe morbidity and mortality of untreated HIV-infected children.
Methods: All HIV-infected children enrolled from 2004-2009 in a prospective HIV programme in two health facilities in Abidjan, Cote d'Ivoire, were eligible from their time of inclusion. Risks of severe morbidity (the first clinical event leading to death or hospitalisation) and mortality were documented retrospectively and estimated using cumulative incidence functions. Associations with baseline characteristics were assessed by competing risk regression models between outcomes and antiretroviral initiation.
Results: 405 children were included at a median age of 4.5 years; at baseline, 66.9% were receiving cotrimoxazole prophylaxis, and 27.7% met the 2006 WHO criteria for immunodeficiency by age. The risk of developing a severe morbid event was 14% (95% CI: 10.7 - 17.8) at 18 months; this risk was lower in children previously exposed to any prevention of mother-to-child-transmission (PMTCT) intervention (adjusted subdistribution hazard ratio [sHR]: 0.16, 95% CI: 0.04 - 0.71) versus those without known exposure. Cumulative mortality reached 5.5% (95% CI: 3.5 - 8.1) at 18 months. Mortality was associated with immunodeficiency (sHR: 6.02, 95% CI: 1.28-28.42).
Conclusions: Having benefited from early access to care minimizes the severe morbidity risk for children who acquire HIV. Despite the receipt of cotrimoxazole prophylaxis, the risk of severe morbidity and mortality remains high in untreated HIV-infected children. Such evidence adds arguments to promote earlier access to ART in HIV-infected children in Africa and improve care interventions in a context where treatment is still not available to all.

AB Background
Tamoxifen and raloxifene have limited patient acceptance for primary prevention of breast cancer. Aromatase inhibitors prevent more contralateral breast cancers and cause fewer side effects than tamoxifen in patients with early-stage breast cancer.
Methods
In a randomized, placebo-controlled, double-blind trial of exemestane designed to detect a 65% relative reduction in invasive breast cancer, eligible postmenopausal women 35 years of age or older had at least one of the following risk factors: 60 years of age or older; Gail 5-year risk score greater than 1.66% (chances in 100 of invasive breast cancer developing within 5 years); prior atypical ductal or lobular hyperplasia or lobular carcinoma in situ; or ductal carcinoma in situ with mastectomy. Toxic effects and health-related and menopause-specific qualities of life were measured.
Results
A total of 4560 women for whom the median age was 62.5 years and the median Gail risk score was 2.3% were randomly assigned to either exemestane or placebo. At a median follow-up of 35 months, 11 invasive breast cancers were detected in those given exemestane and in 32 of those given placebo, with a 65% relative reduction in the annual incidence of invasive breast cancer (0.19% vs. 0.55%; hazard ratio, 0.35; 95% confidence interval [CI], 0.18 to 0.70; P = 0.002). The annual incidence of invasive plus noninvasive (ductal carcinoma in situ) breast cancers was 0.35% on exemestane and 0.77% on placebo (hazard ratio, 0.47; 95% CI, 0.27 to 0.79; P = 0.004). Adverse events occurred in 88% of the exemestane group and 85% of the placebo group (P = 0.003), with no significant differences between the two groups in terms of skeletal fractures, cardiovascular events, other cancers, or treatment-related deaths. Minimal quality-of-life differences were observed.
Conclusions
Exemestane significantly reduced invasive breast cancers in postmenopausal women who were at moderately increased risk for breast cancer. During a median follow-up period of 3 years, exemestane was associated with no serious toxic effects and only minimal changes in health-related quality of life.

AB Congenital dyserythropoietic anemia type 1 (CDA-1), a rare inborn anemia characterized by abnormal chromatin ultrastructure in erythroblasts, is caused by abnormalities in codanin-1, a highly conserved protein of unknown function. We have produced 3 monoclonal antibodies to codanin-1 that demonstrate its distribution in both nucleus and cytoplasm by immunofluorescence and allow quantitative measurements of patient and normal material by Western blot. A detailed analysis of chromatin structure in CDA-1 erythroblasts shows no abnormalities in overall histone composition, and the genome-wide epigenetic landscape of several histone modifications is maintained. However, immunofluorescence analysis of intermediate erythroblasts from patients with CDA-1 reveals abnormal accumulation of HP1 alpha in the Golgi apparatus. A link between mutant codanin-1 and the aberrant localization of HP1 alpha is supported by the finding that codanin-1 can be coimmunoprecipitated by anti-HP1 alpha antibodies. Furthermore, we show colocalization of codanin-1 with Sec23B, the protein defective in CDA-2 suggesting that the CDAs might be linked at the molecular level. Mice containing a gene-trapped Cdan1 locus demonstrate its widespread expression during development. Cdan1(gt/gt) homozygotes die in utero before the onset of primitive erythropoiesis, suggesting that Cdan1 has other critical roles during embryogenesis. (Blood. 2011;117(25):6928-6938)

AB The success of reduced intensity conditioning (RIC) transplantation is largely dependent on alloimmune effects. It is critical to determine whether immune modulation with anti-T-cell antibody infusion abrogates the therapeutic benefits of transplantation. We examined 1676 adults undergoing RIC transplantation for hematologic malignancies. All patients received alkylating agent plus fludarabine; 792 received allografts from a human leukocyte antigen-matched sibling, 884 from a 7 or 8 of 8 HLA-matched unrelated donor. Using Cox regression, outcomes after in vivo T-cell depletion (n = 584 anti-thymocyte globulin [ATG]; n = 213 alemtuzumab) were compared with T cell-replete (n = 879) transplantation. Grade 2 to 4 acute GVHD was lower with alemtuzumab compared with ATG or T cell-replete regimens (19% vs 38% vs 40%, P < .0001) and chronic GVHD, lower with alemtuzumab, and ATG regimens compared with T-replete approaches (24% vs 40% vs 52%, P < .0001). However, relapse was more frequent with alemtuzumab and ATG compared with T cell-replete regimens (49%, 51%, and 38%, respectively, P < .001). Disease-free survival was lower with alemtuzumab and ATG compared with T cell-replete regimens (30%, 25%, and 39%, respectively, P < .001). Corresponding probabilities of overall survival were 50%, 38%, and 46% (P = .008). These data suggest adopting a cautious approach to routine use of in vivo T-cell depletion with RIC regimens.

AB In this paper we provide a review of selected mathematical ideas that can help us better understand the boundary between living and non-living systems. We focus on group theory and abstract algebra applied to molecular systems biology. Throughout this paper we briefly describe possible open problems. In connection with the genetic code we propose that it may be possible to use perturbation theory to explore the adjacent possibilities in the 64-dimensional space-time manifold of the evolving genome.
With regards to algebraic graph theory, there are several minor open problems we discuss. In relation to network dynamics and groupoid formalism we suggest that the network graph might not be the main focus for understanding the phenotype but rather the phase space of the network dynamics. We show a simple case of a C-6 network and its phase space network. We envision that the molecular network of a cell is actually a complex network of hypercycles and feedback circuits that could be better represented in a higher-dimensional space. We conjecture that targeting nodes in the molecular network that have key roles in the phase space, as revealed by analysis of the automorphism decomposition, might be a better way to drug discovery and treatment of cancer.

AB Context A recent meta-analysis demonstrated that statin therapy is associated with excess risk of developing diabetes mellitus.
Objective To investigate whether intensive-dose statin therapy is associated with increased risk of new-onset diabetes compared with moderate-dose statin therapy.
Data Sources We identified relevant trials in a literature search of MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (January 1, 1996, through March 31, 2011). Unpublished data were obtained from investigators.
Study Selection We included randomized controlled end-point trials that compared intensive-dose statin therapy with moderate-dose statin therapy and included more than 1000 participants who were followed up for more than 1 year.
Data Extraction Tabular data provided for each trial described baseline characteristics and numbers of participants developing diabetes and experiencing major cardiovascular events (cardiovascular death, nonfatal myocardial infarction or stroke, coronary revascularization). We calculated trial-specific odds ratios (ORs) for new-onset diabetes and major cardiovascular events and combined these using random-effects model meta-analysis. Between-study heterogeneity was assessed using the I-2 statistic.
Results In 5 statin trials with 32 752 participants without diabetes at baseline, 2749 developed diabetes (1449 assigned intensive-dose therapy, 1300 assigned moderate-dose therapy, representing 2.0 additional cases in the intensive-dose group per 1000 patient years) and 6684 experienced cardiovascular events(3134 and 3550, respectively, representing 6.5 fewer cases in the intensive-dose group per 1000 patient-years) over a weighted mean (SD) follow-up of 4.9 (1.9) years. Odds ratios were 1.12 (95% confidence interval [CI], 1.04-1.22; I-2 = 0%) for new-onset diabetes and 0.84(95% CI, 0.75-0.94; I-2 = 74%) for cardiovascular events for participants receiving intensive therapy compared with moderate-dose therapy. As compared with moderate-dose statin therapy, the number needed to harm per year for intensive-dose statin therapy was 498 for new-onset diabetes while the number needed to treat per year for intensive-dose statin therapy was 155 for cardiovascular events.
Conclusion In a pooled analysis of data from 5 statin trials, intensive-dose statin therapy was associated with an increased risk of new-onset diabetes compared with moderate dose statin therapy. JAMA. 2011;305(24):2556-2564

TI Silymarin Protects Epidermal Keratinocytes from Ultraviolet
Radiation-Induced Apoptosis and DNA Damage by Nucleotide Excision Repair

AB Solar ultraviolet (UV) radiation is a well recognized epidemiologic risk factor for melanoma and non-melanoma skin cancers. This observation has been linked to the accumulation of UVB radiation-induced DNA lesions in cells, and that finally lead to the development of skin cancers. Earlier, we have shown that topical treatment of skin with silymarin, a plant flavanoid from milk thistle (Silybum marianum), inhibits photocarcinogenesis in mice; however it is less understood whether chemopreventive effect of silymarin is mediated through the repair of DNA lesions in skin cells and that protect the cells from apoptosis. Here, we show that treatment of normal human epidermal keratinocytes (NHEK) with silymarin blocks UVB-induced apoptosis of NHEK in vitro. Silymarin reduces the amount of UVB radiation-induced DNA damage as demonstrated by reduced amounts of cyclobutane pyrimidine dimers (CPDs) and as measured by comet assay, and that ultimately may lead to reduced apoptosis of NHEK. The reduction of UV radiation-induced DNA damage by silymarin appears to be related with induction of nucleotide excision repair (NER) genes, because UV radiation-induced apoptosis was not blocked by silymarin in NER-deficient human fibroblasts. Cytostaining and dot-blot analysis revealed that silymarin repaired UV-induced CPDs in NER-proficient fibroblasts from a healthy individual but did not repair UV-induced CPD-positive cells in NER-deficient fibroblasts from patients suffering from xeroderma pigmentosum complementation-A disease. Similarly, immunohistochemical analysis revealed that silymarin did not reduce the number of UVB-induced sunburn/apoptotic cells in the skin of NER-deficient mice, but reduced the number of sunburn cells in their wild-type counterparts. Together, these results suggest that silymarin exert the capacity to reduce UV radiation-induced DNA damage and, thus, prevent the harmful effects of UV radiation on the genomic stability of epidermal cells.

AB Environmental factors, such as the macronutrient composition of the diet, can have a profound impact on risk of diabetes and metabolic syndrome. In the present study we demonstrate how a single, simple dietary factor-leucine-can modify insulin resistance by acting on multiple tissues and at multiple levels of metabolism. Mice were placed on a normal or high fat diet (HFD). Dietary leucine was doubled by addition to the drinking water. mRNA, protein and complete metabolomic profiles were assessed in the major insulin sensitive tissues and serum, and correlated with changes in glucose homeostasis and insulin signaling. After 8 weeks on HFD, mice developed obesity, fatty liver, inflammatory changes in adipose tissue and insulin resistance at the level of IRS-1 phosphorylation, as well as alterations in metabolomic profile of amino acid metabolites, TCA cycle intermediates, glucose and cholesterol metabolites, and fatty acids in liver, muscle, fat and serum. Doubling dietary leucine reversed many of the metabolite abnormalities and caused a marked improvement in glucose tolerance and insulin signaling without altering food intake or weight gain. Increased dietary leucine was also associated with a decrease in hepatic steatosis and a decrease in inflammation in adipose tissue. These changes occurred despite an increase in insulin-stimulated phosphorylation of p70S6 kinase indicating enhanced activation of mTOR, a phenomenon normally associated with insulin resistance. These data indicate that modest changes in a single environmental/nutrient factor can modify multiple metabolic and signaling pathways and modify HFD induced metabolic syndrome by acting at a systemic level on multiple tissues. These data also suggest that increasing dietary leucine may provide an adjunct in the management of obesity-related insulin resistance.

TI Simvastatin Prevents Dopaminergic Neurodegeneration in Experimental

AB Background: In addition to their original applications to lowering cholesterol, statins display multiple neuroprotective effects. N-methyl-D-aspartate (NMDA) receptors interact closely with the dopaminergic system and are strongly implicated in therapeutic paradigms of Parkinson's disease (PD). This study aims to investigate how simvastatin impacts on experimental parkinsonian models via regulating NMDA receptors.
Methodology/Principal Findings: Regional changes in NMDA receptors in the rat brain and anxiolytic-like activity were examined after unilateral medial forebrain bundle lesion by 6-hydroxydopamine via a 3-week administration of simvastatin. NMDA receptor alterations in the post-mortem rat brain were detected by [(3)H]MK-801(Dizocilpine) binding autoradiography. 6-hydroxydopamine treated PC12 was applied to investigate the neuroprotection of simvastatin, the association with NMDA receptors, and the anti-inflammation. 6-hydroxydopamine induced anxiety and the downregulation of NMDA receptors in the hippocampus, CA1(Cornu Ammonis 1 Area), amygdala and caudate putamen was observed in 6-OHDA(6-hydroxydopamine) lesioned rats whereas simvastatin significantly ameliorated the anxiety-like activity and restored the expression of NMDA receptors in examined brain regions. Significant positive correlations were identified between anxiolytic-like activity and the restoration of expression of NMDA receptors in the hippocampus, amygdala and CA1 following simvastatin administration. Simvastatin exerted neuroprotection in 6-hydroxydopamine-lesioned rat brain and 6-hydroxydopamine treated PC12, partially by regulating NMDA receptors, MMP9 (matrix metalloproteinase-9), and TNF-a (tumour necrosis factor-alpha).
Conclusions/Significance: Our results provide strong evidence that NMDA receptor modulation after simvastatin treatment could partially explain its anxiolytic-like activity and anti-inflammatory mechanisms in experimental parkinsonian models. These findings contribute to a better understanding of the critical roles of simvastatin in treating PD via NMDA receptors.

AB Background: Target specific antibodies are pivotal for the design of vaccines, immunodiagnostic tests, studies on proteomics for cancer biomarker discovery, identification of protein-DNA and other interactions, and small and large biochemical assays. Therefore, it is important to understand the properties of protein sequences that are important for antigenicity and to identify small peptide epitopes and large regions in the linear sequence of the proteins whose utilization result in specific antibodies.
Results: Our analysis using protein properties suggested that sequence composition combined with evolutionary information and predicted secondary structure, as well as solvent accessibility is sufficient to predict successful peptide epitopes. The antigenicity and the specificity in immune response were also found to depend on the epitope length. We trained the B-Cell Epitope Oracle (BEOracle), a support vector machine (SVM) classifier, for the identification of continuous B-Cell epitopes with these protein properties as learning features. The BEOracle achieved an F1-measure of 81.37% on a large validation set. The BEOracle classifier outperformed the classical methods based on propensity and sophisticated methods like BCPred and Bepipred for B-Cell epitope prediction. The BEOracle classifier also identified peptides for the ChIP-grade antibodies from the modENCODE/ ENCODE projects with 96.88% accuracy. High BEOracle score for peptides showed some correlation with the antibody intensity on Immunofluorescence studies done on fly embryos. Finally, a second SVM classifier, the B-Cell Region Oracle (BROracle) was trained with the BEOracle scores as features to predict the performance of antibodies generated with large protein regions with high accuracy. The BROracle classifier achieved accuracies of 75.2663.88% on a validation set with immunofluorescence, immunohistochemistry, protein arrays and western blot results from Protein Atlas database.
Conclusions: Together our results suggest that antigenicity is a local property of the protein sequences and that protein sequence properties of composition, secondary structure, solvent accessibility and evolutionary conservation are the determinants of antigenicity and specificity in immune response. Moreover, specificity in immune response could also be accurately predicted for large protein regions without the knowledge of the protein tertiary structure or the presence of discontinuous epitopes.

AB Objectives Because fluorodeoxyglucose positron emission tomography (FDG-PET) imaging provides a noninvasive index of inflammation, we sought to assess whether FDG uptake in the aortic valve (AV) is increased in aortic stenosis (AS).
Background AS is associated with valvular inflammation.
Methods FDG-PET/computed tomography data were retrospectively evaluated in 84 patients (age 73 +/- 9 years, 45% female), 42 patients with AS, and 42 age-matched controls. FDG uptake was determined within the AV while blinded to AS severity. Target-to-background ratio (TBR) was calculated as valvular/blood activity. Stenosis severity was established on echocardiography, and presence of AV calcification was independently assessed on computed tomography.
Results The aortic valve PET signal (TBR) was increased in AS compared with controls (median 1.53 [interquartile range (IQR): 1.42 to 1.76] vs. 1.34 [IQR: 1.20 to 1.55]; p < 0.001). Further, compared with controls, TBR was increased in mild (median 1.50 [IQR: 1.36 to 1.75]; p = 0.01) and moderate (median 1.70 [IQR: 1.52 to 1.94]; p < 0.001), but not in severe AS (median 1.49 [IQR: 1.40 to 1.54]; p = 0.08). When subjects were categorized according to AV calcification, valvular FDG uptake was increased in mildly (median 1.50 [IQR: 1.36 to 1.79]; p < 0.01) and moderately (median 1.67 [IQR: 1.50 to 1.85]; p < 0.001), but not severely calcified valves (median 1.51 [IQR: 1.38 to 1.54]; p = 0.15), compared with noncalcified valves (median 1.35 [IQR: 1.20 to 1.52]).
Conclusions This study supports the hypothesis that AS is an inflammatory condition and suggests that inflammation may be reduced in late-stage disease. This may have important implications in the design of studies assessing the effect of therapeutic agents in modifying progression of AS.

AB Objectives This study sought to develop a 2-dimensional (2D) intravascular near-infrared fluorescence (NIRF) imaging strategy for investigation of arterial inflammation in coronary-sized vessels.
Background Molecular imaging of arterial inflammation could provide new insights into the pathogenesis of acute myocardial infarction stemming from coronary atheromata and implanted stents. Presently, few high-resolution approaches can image inflammation in coronary-sized arteries in vivo.
Methods A new 2.9-F rotational, automated pullback 2D imaging catheter was engineered and optimized for 360 degrees viewing intravascular NIRF imaging. In conjunction with the cysteine protease-activatable imaging reporter Prosense VM110 (VisEn Medical, Woburn, Massachusetts), intra-arterial 2D NIRF imaging was performed in rabbit aortas with atherosclerosis (n = 10) or implanted coronary bare-metal stents (n = 10, 3.5-mm diameter, day 7 post-implantation). Intravascular ultrasound provided coregistered anatomical images of arteries. After sacrifice, specimens underwent ex vivo NIRF imaging, fluorescence microscopy, and histological and immunohistochemical analyses.
Results Imaging of coronary artery-scaled phantoms demonstrated 8-sector angular resolution and submillimeter axial resolution, nanomolar sensitivity to NIR fluorochromes, and modest NIRF light attenuation through blood. High-resolution NIRF images of vessel wall inflammation with signal-to-noise ratios > 10 were obtained in real-time through blood, without flushing or occlusion. In atherosclerosis, 2D NIRF, intravascular ultrasound-NIRF fusion, microscopy, and immunoblotting studies provided insight into the spatial distribution of plaque protease activity. In stent-implanted vessels, real-time imaging illuminated an edge-based pattern of stent-induced arterial inflammation.
Conclusions A new 2D intravascular NIRF imaging strategy provides high-resolution in vivo spatial mapping of arterial inflammation in coronary-sized arteries and reveals increased inflammation-regulated cysteine protease activity in atheromata and stent-induced arterial injury.

ID INTERACTION MAP; NETWORK; YEAST; CLOSURE; GENES; LIFE
AB Background: We review and extend the work of Rosen and Casti who discuss category theory with regards to systems biology and manufacturing systems, respectively.
Results: We describe anticipatory systems, or long-range feed-forward chemical reaction chains, and compare them to open-loop manufacturing processes. We then close the loop by discussing metabolism-repair systems and describe the rationality of the self-referential equation f = f (f). This relationship is derived from some boundary conditions that, in molecular systems biology, can be stated as the cardinality of the following molecular sets must be about equal: metabolome, genome, proteome. We show that this conjecture is not likely correct so the problem of self-referential mappings for describing the boundary between living and nonliving systems remains an open question. We calculate a lower and upper bound for the number of edges in the molecular interaction network (the interactome) for two cellular organisms and for two manufacturomes for CMOS integrated circuit manufacturing.
Conclusions: We show that the relevant mapping relations may not be Abelian, and that these problems cannot yet be resolved because the interactomes and manufacturomes are incomplete.

AB Purpose
To compare characteristics and outcomes of breast cancer in women with and without a history of radiation therapy (RT) for Hodgkin's lymphoma (HL).
Patients and Methods
Women with breast cancer diagnosed from 1980 to 2006 after RT for HL were identified from eight North American hospitals and were matched three-to-one with patients with sporadic breast cancer by age, race, and year of breast cancer diagnosis. Information on patient, tumor and treatment characteristics, and clinical outcomes was abstracted from medical records.
Results
A total of 253 patients with breast cancer with a history of RT for HL were matched with 741 patients with sporadic breast cancer. Median time from HL to breast cancer diagnosis was 18 years. Median age at breast cancer diagnosis was 42 years. Breast cancer after RT for HL was more likely to be detected by screening, was more likely to be diagnosed at an earlier stage, and was more likely to be bilateral at diagnosis. HL survivors had an increased risk of metachronous contralateral breast cancer (adjusted hazard ratio [HR], 4.3; 95% CI, 1.7 to 11.0) and death as a result of any cause (adjusted HR, 1.9; 95% CI, 1.1 to 3.3). Breast cancer-specific mortality was also elevated, but this difference was not statistically significant (adjusted HR, 1.6; 95% CI, 0.7 to 3.4).
Conclusion
In women with a history of RT for HL, breast cancer is diagnosed at an earlier stage, but these women are at greater risk for bilateral disease and are more likely to die as a result of causes other than breast cancer. Our findings support close follow-up for contralateral tumors in these patients and ongoing primary care to manage comorbid conditions.

AB Purpose
Androgen deprivation therapy (ADT), an important treatment for advanced prostate cancer, is highly variable in its effectiveness. We hypothesized that genetic variants of androgen transporter genes, SLCO2B1 and SLCO1B3, may determine time to progression on ADT.
Patients and Methods
A cohort of 538 patients with prostate cancer treated with ADT was genotyped for SLCO2B1 and SLCO1B3 single nucleotide polymorphisms (SNP). The biologic function of a SLCO2B1 coding SNP in transporting androgen was examined through biochemical assays.
Results
Three SNPs in SLCO2B1 were associated with time to progression (TTP) on ADT (P < .05). The differences in median TTP for each of these polymorphisms were about 10 months. The SLCO2B1 genotype, which allows more efficient import of androgen, enhances cell growth and is associated with a shorter TTP on ADT. Patients carrying both SLCO2B1 and SLCO1B3 genotypes, which import androgens more efficiently, exhibited a median 2-year shorter TTP on ADT, demonstrating a gene-gene interaction (P-interaction = .041).
Conclusion
Genetic variants of SLCO2B1 and SLCO1B3 may function as pharmacogenomic determinants of resistance to ADT in prostate cancer. J Clin Oncol 29:2565-2573. (C) 2011 by American Society of Clinical Oncology

AB Objective: To report the effects of tesamorelin, a growth hormone-releasing hormone analogue, on inflammatory and fibrinolytic markers and to relate these effects to changes in visceral adipose tissue (VAT).
Design and methods: Four hundred and ten HIV-infected patients with abdominal adiposity were randomized to 2mg tesamorelin (n = 273) or placebo (n = 137) subcutaneously daily for 26 weeks. Circulating plasminogen activator inhibitor-1 (PAI-1) antigen, tissue plasminogen activator (tPA) antigen, C-reactive protein (CRP), and adiponectin were assessed.
Results: At baseline, VAT was significantly associated with PAI-1 antigen (rho = 0.36, P<0.001), tPA antigen (rho = 0.29, P<0.001), CRP (rho = 0.18, P<0.001), and adiponectin (rho = -0.22, P<0.001). Treatment with tesamorelin resulted in a significant decrease from baseline in tPA antigen (-2.2 +/- 2.5 vs. -1.6 +/- 2.9 ng/ml, tesamorelin vs. placebo, P<0.05). Changes in PAI-1 antigen were not significant in the tesamorelin group compared to placebo. Among patients receiving tesamorelin, changes in inflammatory markers were associated with change in VAT (PAI-1 antigen: rho = 0.16, P = 0.02; tPA antigen: rho = 0.16, P = 0.02; adiponectin: rho = -0.27, P<0.001), and these associations remained significant when controlling for changes in insulin-like growth factor-1.
Conclusion: In HIV patients with abdominal adiposity, tesamorelin may have a modest beneficial effect on adiponectin and fibrinolytic markers in association with changes in VAT. Further studies are needed to determine the clinical significance of these changes. These data further highlight the deleterious role of excessive VAT and the utility of strategies to improve VAT in this population.

AB Objective: Abacavir use has been associated with cardiovascular risk, but it is unknown whether this association may be partly explained by patients with kidney disease being preferentially treated with abacavir to avoid tenofovir. Our objective was to compare associations of abacavir and tenofovir with cardiovascular risks in HIV-infected veterans.
Design: Cohort study of 10 931 HIV-infected patients initiating antiretroviral therapy in the Veterans Health Administration from 1997 to 2007, using proportional hazards survival regression.
Methods: Primary predictors were exposure to abacavir or tenofovir within the past 6 months, compared with no exposure to these drugs, respectively. Outcomes were time to first atherosclerotic cardiovascular event, defined as coronary, cerebrovascular, or peripheral arterial disease; and time to incident heart failure.
Results: Over 60 588 person-years of observation, there were 501 cardiovascular and 194 heart failure events. Age-standardized event rates among abacavir and tenofovir users were 12.5 versus 8.2 per 1000 person-years for cardiovascular disease, and 3.9 and 3.7 per 1000 person-years for heart failure, respectively. In multivariate-adjusted models, including time-updated measurements of kidney function, recent abacavir use was significantly associated with incident cardiovascular disease [hazard ratio 1.48, 95% confidence interval (CI) 1.08-2.04]; the association was similar but nonsignificant for heart failure (1.45, 0.85-2.47). In contrast, recent tenofovir use was significantly associated with heart failure (1.82, 1.02-3.24), but not with cardiovascular events (0.78, 0.52-1.16).
Conclusion: Recent abacavir exposure was independently associated with increased risk for cardiovascular events. We also observed an association between recent tenofovir exposure and heart failure, which needs to be confirmed in future studies.

AB Background: One of the challenges in the interpretation of studies showing associations between environmental and genotypic data with disease outcomes such as neovascular age-related macular degeneration (AMD) is understanding the phenotypic heterogeneity within a patient population with regard to any risk factor associated with the condition. This is critical when considering the potential therapeutic response of patients to any drug developed to treat the condition. In the present study, we identify patient subtypes or clusters which could represent several different targets for treatment development, based on genetic pathways in AMD and cardiovascular pathology.
Methods: We identified a sample of patients with neovascular AMD, that in previous studies had been shown to be at elevated risk for the disease through environmental factors such as cigarette smoking and genetic variants including the complement factor H gene (CFH) on chromosome 1q25 and variants in the ARMS2/HtrA serine peptidase 1 (HTRA1) gene(s) on chromosome 10q26. We conducted a multivariate segmentation analysis of 253 of these patients utilizing available epidemiologic and genetic data.
Results: In a multivariate model, cigarette smoking failed to differentiate subtypes of patients. However, four meaningfully distinct clusters of patients were identified that were most strongly differentiated by their cardiovascular health status (histories of hypercholesterolemia and hypertension), and the alleles of ARMS2/HTRA1 rs1049331.
Conclusions: These results have significant personalized medicine implications for drug developers attempting to determine the effective size of the treatable neovascular AMD population. Patient subtypes or clusters may represent different targets for therapeutic development based on genetic pathways in AMD and cardiovascular pathology, and treatments developed that may elevate CV risk, may be ill advised for certain of the clusters identified.

AB Previous studies have demonstrated expression of Toll-like receptors (TLRs) in the surface epithelium of normal ovaries (USE) and in epithelial ovarian tumors. Most notably, USE-derived cancers express TLR4, which activates the nuclear factor-kappa B (NF-kappa B) signaling cascade as a mediator of inflammatory response. Currently, there is considerable interest in elucidating the role of TLR-mediated signaling in cancers. Nevertheless, the expression of TLRs in granulosa cell tumors (GCTs) of the ovary, and the extent to which GCT expression of TLRs may influence cell-signaling pathways and/or modulate the efficacy of chemotherapeutics, has yet to be determined. In the present study, human GCT lines (COV434 and KGN) were utilized to evaluate expression of functional TLR4. TLR4 is expressed in GCT cell lines and ligation of TLR4 with bacterial lipopolysaccharide (LPS) led to I kappa B degradation and activation of NF-kappa B. NF-kappa B activation was confirmed by nuclear localization of NF-kappa B p65 following treatment with LPS and the naturally occurring ligand, HSP60. Notably, immunoneutralization of TLR4 blocked nuclear localization, and inhibition of NF-kappa B signaling attenuated LPS-induced TNF alpha plus increased doubling time in both cell lines. Contradictory to reports using human USE cell lines, inhibition of NF-kappa B signaling failed to sensitize GCT lines to TRAIL or cisplatin. In summary, findings herein are the first to demonstrate a functional TLR-signaling pathway specifically in GCTs, and indicate that in contrast to USE-derived cancers, inhibition of NF-kappa B does not sensitize GCTs to TRAIL or cisplatin.

AB Nesfatin-1 reduces food intake when injected centrally in rodents. We recently described wide distribution of nucleobindin2 (NUCB2)/nesfatin-1 immunoreactivity in rat brain autonomic nuclei activated by various stressors. We used C57BL/6 mice to localize brain NUCB2/nesfatin-1 immunoreactivity and assessed activation of NUCB2/nesfatin 1 neurons after water avoidance stress (WAS). Gastric emptying of a non-nutrient liquid was also determined. NUCB2/nesfatin-1 immunoreactivity was detected in cortical areas including piriform, insular, cingulate and somatomotor cortices, the limbic system including amygdaloid nuclei, hippocampus and septum, the basal ganglia, bed nucleus of the stria terminalis, the thalamus including paraventricular and parafascicular nuclei, the hypothalamus including supraoptic, periventricular, paraventricular (PVN), arcuate nuclei and ventromedial and lateral hypothalamic areas. Intensely labeled NUCB2/nesfatin-1 neurons were detected in a previously undefined region which we named intermediate dorsomedial hypothalamus. In the brainstem, NUCB2/nesfatin-1 immunoreactivity was detected in the raphe nuclei, Edinger-Westphal nucleus, locus coeruleus (LC), lateral parabrachial nucleus, ventrolateral medulla (VLM) and dorsal vagal complex. WAS induced Fos expression in 35% of NUCB2/nesfatin-1-immunoreactive neurons in the PVN, 50% in the LC, 54% in the rostral raphe pallidus, 58% in the VLM, 39% in the middle part of the nucleus of the solitary tract (NTS) and 33% in the caudal NTS. Nesfatin-1 injected intracerebroventricularly significantly decreased gastric emptying. These data showed that NUCB2/nesfatin-1 immunoreactivity is distributed in mouse brain areas involved in the regulation of stress response and visceral functions activated by an acute psychological stressor suggesting that nesfatin-1 might play a role in the efferent component of the stress response.

TI Ticagrelor versus clopidogrel in patients with acute coronary syndromes
intended for non-invasive management: substudy from prospective
randomised PLATelet inhibition and patient Outcomes (PLATO) trial

AB Objective To evaluate efficacy and safety outcomes in patients in the PLATelet inhibition and patient Outcomes (PLATO) trial who at randomisation were planned for a non-invasive treatment strategy.
Design Pre-specified analysis of pre-randomisation defined subgroup of prospective randomised clinical trial.
Setting 862 centres in 43 countries.
Participants 5216 (28%) of 18 624 patients admitted to hospital for acute coronary syndrome who were specified as planned for non-invasive management.
Interventions Randomised treatment with ticagrelor (n=2601) versus clopidogrel (2615).
Main outcome measurements Primary composite end point of cardiovascular death, myocardial infarction, and stroke; their individual components; and PLATO defined major bleeding during one year.
Results 2183 (41.9%) patients had coronary angiography during their initial hospital admission, 1065 (20.4%) had percutaneous coronary intervention, and 208 (4.0%) had coronary artery bypass surgery. Cumulatively, 3143 (60.3%) patients had been managed non-invasively by the end of follow-up. The incidence of the primary end point was lower with ticagrelor than with clopidogrel (12.0% (n=295) v 14.3% (346); hazard ratio 0.85, 95% confidence interval 0.73 to 1.00; P=0.04). Overall mortality was also lower (6.1% (147) v 8.2% (195); 0.75, 0.61 to 0.93; P=0.01). The incidence of total major bleeding (11.9% (272) v 10.3% (238); 1.17, 0.98 to 1.39; P=0.08) and non-coronary artery bypass grafting related major bleeding (4.0% (90) v 3.1% (71); 1.30, 0.95 to 1.77; P=0.10) was numerically higher with ticagrelor than with clopidogrel.
Conclusions In patients with acute coronary syndrome initially intended for non-invasive management, the benefits of ticagrelor over clopidogrel were consistent with those from the overall PLATO results, indicating the broad benefits of P2Y12 inhibition with ticagrelor regardless of intended management strategy.

AB Gossip is a form of affective information about who is friend and who is foe. We show that gossip does not influence only how a face is evaluated-it affects whether a face is seen in the first place. In two experiments, neutral faces were paired with negative, positive, or neutral gossip and were then presented alone in a binocular rivalry paradigm (faces were presented to one eye, houses to the other). In both studies, faces previously paired with negative (but not positive or neutral) gossip dominated longer in visual consciousness. These findings demonstrate that gossip, as a potent form of social affective learning, can influence vision in a completely top-down manner, independent of the basic structural features of a face.

AB Background: Overweight and obesity during pregnancy raise the risk of gestational diabetes and birth complications. Lifestyle factors like physical activity may decrease these risks through beneficial effects on glucose homeostasis. Here we examined physical activity patterns and their relationships with measures of glucose homeostasis in late pregnancy compared to non-pregnant women.
Methods: Normal weight and overweight women without diabetes (N = 108; aged 25-35 years) were studied; 35 were pregnant (in gestational weeks 28-32) and 73 were non-pregnant. Insulin sensitivity and beta-cell response were estimated from an oral glucose tolerance test. Physical activity was measured during 10-days of free-living using a combined heart rate sensor and accelerometer. Total (TEE), resting (REE), and physical activity (PAEE) energy expenditure were measured using doubly-labeled water and expired gas indirect calorimetry.
Results: Total activity was associated with reduced first-phase insulin response in both pregnant (Regression r(2) = 0.11; Spearman r = -0.47; p = 0.007) and non-pregnant women (Regression r2 = 0.11 Spearman; r = -0.36; p = 0.002). Relative to non-pregnant women, pregnant women were estimated to have secreted 67% more insulin and had 10% lower fasting glucose than non-pregnant women. Pregnant women spent 13% more time sedentary, 71% less time in moderate-to-vigorous intensity activity, had 44% lower objectively measured total activity, and 12% lower PAEE than non-pregnant women. Correlations did not differ significantly for any comparison between physical activity subcomponents and measures of insulin sensitivity or secretion.
Conclusions: Our findings suggest that physical activity conveys similar benefits on glucose homeostasis in pregnant and non-pregnant women, despite differences in subcomponents of physical activity.

TI Concordant and opposite roles of DNA-PK and the "facilitator of

after cisplatin

AB Background: Platinum-containing chemotherapy produces specific DNA damage and is used to treat several human solid tumors. Tumors initially sensitive to platinum-based drugs frequently become resistant. Inhibition of DNA repair is a potential strategy to enhance cisplatin effectiveness. After cisplatin treatment, a balance between repair and apoptosis determines whether cancer cells proliferate or die. DNA-dependent protein kinase (DNA-PK) binds to DNA double strand breaks (DSBs) through its Ku subunits and initiates non-homologous end joining. Inhibition of DNA-PK sensitizes cancer cells to cisplatin killing. The goal of this study is to elucidate the mechanism underlying the effects of DNA-PK on cisplatin sensitivity.
Results: Silencing the expression of the catalytic subunit of DNA-PK (DNA-PKcs) increased sensitivity to cisplatin and decreased the appearance of gamma H2AX after cisplatin treatment. We purified DNA-PK by its Ku86 subunit and identified interactors by tandem mass spectrometry before and after cisplatin treatment. The structure specific recognition protein 1 (SSRP1), Spt16 and gamma H2AX appeared in the Ku86 complex 5 hours after cisplatin treatment. SSRP1 and Spt16 form the facilitator of chromatin transcription (FACT). The cisplatin-induced association of FACT with Ku86 and gamma H2AX was abrogated by DNase treatment. In living cells, SSRP1 and Ku86 were recruited at sites of DSBs induced by laser beams. Silencing SSRP1 expression increased sensitivity to cisplatin and decreased gamma H2AX appearance. However, while silencing SSRP1 in cisplatin-treated cells increased both apoptosis and necrosis, DNA-PKcs silencing, in contrast, favored necrosis over apoptosis.
Conclusions: DNA-PK and FACT both play roles in DNA repair. Therefore both are putative targets for therapeutic inhibition. Since DNA-PK regulates apoptosis, silencing DNA-PKcs redirects cells treated with cisplatin toward necrosis. Silencing FACT however, allows both apoptosis and necrosis. Targeting DNA repair in cancer patients may have different therapeutic effects depending upon the roles played by factors targeted.

AB The clinical outcome of granulocyte transfusion therapy is often hampered by short ex vivo shelf life, inefficiency of recruitment to sites of inflammation, and poor pathogen-killing capability of transplanted neutrophils. Here, using a recently developed mouse granulocyte transfusion model, we revealed that the efficacy of granulocyte transfusion can be significantly increased by elevating intracellular phosphatidylinositol (3,4,5)trisphosphate signaling with a specific phosphatase and tensin homolog deleted on chromosome 10 (PTEN) inhibitor SF1670. Neutrophils treated with SF1670 were much sensitive to chemoattractant stimulation. Neutrophil functions, such as phagocytosis, oxidative burst, polarization, and chemotaxis, were augmented after SF1670 treatment. The recruitment of SF1670-pretreated transfused neutrophils to the inflamed peritoneal cavity and lungs was significantly elevated. In addition, transfusion with SF1670-treated neutrophils led to augmented bacteria-killing capability (decreased bacterial burden) in neutropenic recipient mice in both peritonitis and bacterial pneumonia. Consequently, this alleviated the severity of and decreased the mortality of neutropenia-related pneumonia. Together, these observations demonstrate that the innate immune responses can be enhanced and the severity of neutropenia-related infection can be alleviated by augmenting phosphatidylinositol (3,4,5)-trisphosphate in transfused neutrophils with PTEN inhibitor SF1670, providing a therapeutic strategy for improving the efficacy of granulocyte transfusion.

ID VERSUS-HOST-DISEASE; CHRONIC GRAFT; SURVIVAL; CLASSIFICATION; SEVERITY;
CRITERIA
AB Several risk factors are associated with increased mortality in patients with chronic graft-versus-host disease (cGVHD), but there is considerable variability in the reported factors. Therefore, we evaluated patient, transplantation, and cGVHD characteristics to develop a risk score in 5343 patients with cGVHD. Ten variables were identified as being significant in multivariate analysis of overall survival and nonrelapse mortality (NRM): age, prior acute GVHD, time from trans-plantation to cGVHD, donor type, disease status at transplantation, GVHD prophylaxis, gender mismatch, serum bilirubin, Karnofsky score, and platelet count. These 10 variables were used to build a cGVHD risk score, and 6 risk groups (RGs) were identified. The 5-year NRM was 5% (1%-9%) in RG1, 20% (19%-23%) in RG2, 33% (29%-37%) in RG3, 43% (40%-46%) in RG4, 63% (53%-74%) in RG5, and 72% (59%-85%) in RG6. The 5-year overall survival was highest at 91% (95% confidence interval [CI]: 85%-97%) in RG1, followed by 67% (65%-69%) in RG2, 51% (46%-55%) in RG3, 40% (37%-43%) in RG4, 21% (12%-30%) in RG5, and 4% (0%-9%) in RG6 (all P < .01). This analysis demonstrates the usefulness of data from a large registry to develop risk-score categories for major transplantation outcomes. Validation of this cGVHD risk score is needed in a different population to ensure its broad applicability. (Blood. 2011;117(24):6714-6720)

AB Acute kidney injury (AKI) is associated with increased rates of mortality. For unknown reasons, HIV infected individuals have a higher risk of AKI than uninfected persons. We tested our hypothesis that increased circulating LPS increases renal expression of HIV and that HIV transgenic (Tg26) mice have increased susceptibility to AKI. Tg26 mice harbor an HIV transgene encoding all HIV genes except gag and pol, and develop a phenotype analogous to HIVAN. Mice were used at 4-6 weeks of age before the onset of gross renal disease. Mice were injected i.p. with LPS or sterile saline. Renal function, tubular injury, cytokine expression, and HIV transcription were evaluated in Tg26 and wild type (WT) mice. LPS injection induced a median 60.1-fold increase in HIV expression in spleen but no change in kidney. There was no significant difference in renal function, cytokine expression, or tubular injury scores at baseline or 24 hours after LPS injection. HIV transcription was also analyzed in vitro using a human renal tubular epithelial cell (RTEC) line. HIV transcription increased minimally in human RTEC, by 1.47 fold, 48 hours after LPS exposure. We conclude that Tg26 mice do not increase HIV expression or have increased susceptibility to LPS induced AKI. The increased risk of AKI in HIV infected patients is not mediated via increased renal expression of HIV in the setting of sepsis. Moreover, renal regulation of HIV transcription is different to that in the spleen.

AB Background: The type 2 iodothyronine deiodinase (D2) converts the pro-hormone thyroxine into T3 within target tissues. D2 is essential for a full thermogenic response of brown adipose tissue (BAT), and mice with a disrupted Dio2 gene (D2KO) have an impaired response to cold. BAT is also activated by overfeeding.
Methodology/Principal Findings: After 6-weeks of HFD feeding D2KO mice gained 5.6% more body weight and had 28% more adipose tissue. Oxygen consumption (V0(2)) was not different between genotypes, but D2KO mice had an increased respiratory exchange ratio (RER), suggesting preferential use of carbohydrates. Consistent with this, serum free fatty acids and b-hydroxybutyrate were lower in D2KO mice on a HFD, while hepatic triglycerides were increased and glycogen content decreased. Neither genotype showed glucose intolerance, but D2KO mice had significantly higher insulin levels during GTT independent of diet. Accordingly, during ITT testing D2KO mice had a significantly reduced glucose uptake, consistent with insulin resistance. Gene expression levels in liver, muscle, and brown and white adipose tissue showed no differences that could account for the increased weight gain in D2KO mice. However, D2KO mice have higher PEPCK mRNA in liver suggesting increased gluconeogenesis, which could also contribute to their apparent insulin resistance.
Conclusions/Significance: We conclude that the loss of the Dio2 gene has significant metabolic consequences. D2KO mice gain more weight on a HFD, suggesting a role for D2 in protection from diet-induced obesity. Further, D2KO mice appear to have a greater reliance on carbohydrates as a fuel source, and limited ability to mobilize and to burn fat. This results in increased fat storage in adipose tissue, hepatic steatosis, and depletion of liver glycogen in spite of increased gluconeogenesis. D2KO mice are also less responsive to insulin, independent of diet-induced obesity.

AB Recent advances have provided substantial insight into the maintenance of mucosal immunity and the pathogenesis of inflammatory bowel disease. Cellular programs responsible for intestinal homeostasis use diverse intracellular and intercellular networks to promote immune tolerance, inflammation or epithelial restitution. Complex interfaces integrate local host and microbial signals to activate appropriate effector programs selectively and even drive plasticity between these programs. In addition, genetic studies and mouse models have emphasized the role of genetic predispositions and how they affect interactions with microbial and environmental factors, leading to pro-colitogenic perturbations of the host-commensal relationship.

AB Transforming growth factor (TGF)-beta is stored in the extracellular matrix as a latent complex with its prodomain. Activation of TGF-beta 1 requires the binding of alpha(v) integrin to an RGD sequence in the prodomain and exertion of force on this domain, which is held in the extracellular matrix by latent TGF-beta binding proteins. Crystals of dimeric porcine proTGF-beta 1 reveal a ring-shaped complex, a novel fold for the prodomain, and show how the prodomain shields the growth factor from recognition by receptors and alters its conformation. Complex formation between alpha(v)beta(6) integrin and the prodomain is insufficient for TGF-beta 1 release. Force-dependent activation requires unfastening of a 'straitjacket' that encircles each growth-factor monomer at a position that can be locked by a disulphide bond. Sequences of all 33 TGF-beta family members indicate a similar prodomain fold. The structure provides insights into the regulation of a family of growth and differentiation factors of fundamental importance in morphogenesis and homeostasis.

AB Background: Recent advances in the field of metabolic engineering have been expedited by the availability of genome sequences and metabolic modelling approaches. The complete sequencing of the C. reinhardtii genome has made this unicellular alga a good candidate for metabolic engineering studies; however, the annotation of the relevant genes has not been validated and the much-needed metabolic ORFeome is currently unavailable. We describe our efforts on the functional annotation of the ORF models released by the Joint Genome Institute (JGI), prediction of their subcellular localizations, and experimental verification of their structural annotation at the genome scale.
Results: We assigned enzymatic functions to the translated JGI ORF models of C. reinhardtii by reciprocal BLAST searches of the putative proteome against the UniProt and AraCyc enzyme databases. The best match for each translated ORF was identified and the EC numbers were transferred onto the ORF models. Enzymatic functional assignment was extended to the paralogs of the ORFs by clustering ORFs using BLASTCLUST. In total, we assigned 911 enzymatic functions, including 886 EC numbers, to 1,427 transcripts. We further annotated the enzymatic ORFs by prediction of their subcellular localization. The majority of the ORFs are predicted to be compartmentalized in the cytosol and chloroplast. We verified the structure of the metabolism-related ORF models by reverse transcription-PCR of the functionally annotated ORFs. Following amplification and cloning, we carried out 454FLX and Sanger sequencing of the ORFs. Based on alignment of the 454FLX reads to the ORF predicted sequences, we obtained more than 90% coverage for more than 80% of the ORFs. In total, 1,087 ORF models were verified by 454 and Sanger sequencing methods. We obtained expression evidence for 98% of the metabolic ORFs in the algal cells grown under constant light in the presence of acetate.
Conclusions: We functionally annotated approximately 1,400 JGI predicted metabolic ORFs that can facilitate the reconstruction and refinement of a genome-scale metabolic network. The unveiling of the metabolic potential of this organism, along with structural verification of the relevant ORFs, facilitates the selection of metabolic engineering targets with applications in bioenergy and biopharmaceuticals. The ORF clones are a resource for downstream studies.

AB The senescent immune system responds poorly to new stimuli; thymic involution, accumulation of memory cells against other specificities, and general refractoriness to antigen signaling all may contribute to poor resistance to infection. These same changes may pose a significant clinical barrier to organ transplantation, as transplantation tolerance requires thymic participation and integrated, tolerance-promoting responses to novel antigens. We found that after the age of 12 months, mice became resistant to the tolerance-inducing capacity of the monoclonal antibody therapy anti-CD45RB. This resistance to tolerance to cardiac allografts could be overcome by surgical castration of male mice, a procedure that led to thymic regeneration and long-term graft acceptance. The potential for clinical translation of this endocrine-immune interplay was confirmed by the ability of Lupron Depot injections, which temporarily disrupt gonadal function, to restore tolerance in aged mice. Furthermore, we demonstrated that the restoration of tolerance after surgical or chemical castration depended on thymic production of regulatory T cells (T(regs)); thymectomy or T(reg) depletion abrogated tolerance restoration. The aging of the immune system ("immune senescence") is a significant barrier to immune tolerance, but this barrier can be overcome by targeting sex steroid production with commonly used clinical therapeutics.

SO CANCER RESEARCH

AB Phosphoinositide 3-kinase (PI3K) is an important therapeutic target. Mutations in PIK3CA, which encodes p110 alpha, the catalytic subunit of PI3K, occur in endometrioid endometrial cancers (EEC) and nonendometrioid endometrial cancers (NEEC). The goal of this study was to determine whether PIK3R1, which encodes p85 alpha, the inhibitory subunit of PI3K, is mutated in endometrial carcinoma. We carried out exonic sequencing of PIK3R1 from 42 EECs and 66 NEECs. The pattern of PIK3R1 mutations was compared with the patterns of PIK3CA, PTEN, and KRAS mutations. The biochemical effect of seven PIK3R1 mutations was examined by stable expression in U2OS cells, followed by coimmunoprecipitation analysis of p110 alpha, and Western blotting of phospho-AKT(Ser473) (p-AKT(Ser473)). We found that PIK3R1 was somatically mutated in 43% of EECs and 12% of NEECs. The majority of mutations (93.3%) were localized to the p85 alpha-nSH2 and -iSH2 domains. Several mutations were recurrent. PIK3R1 mutations were significantly (P = 0.0015) more frequent in PIK3CA-wild type EECs (70%) than in PIK3CA mutant EECs (18%). Introduction of wild-type p85 alpha into U2OS cells reduced the level of p-AKT(Ser473) compared with the vector control. Five p85 alpha mutants, p85 alpha delH450-E451, p85 alpha delK459, p85 alpha delY463-L466, p85 alpha delR574-T576, and the p85 alpha N564D positive control, were shown to bind p110 alpha and led to increased levels of p-AKT(Ser473). The p85 alpha R348X and p85 alpha K511VfsX2 mutants did not bind p110 alpha and showed no appreciable change in p-AKT(Ser473) levels. In conclusion, our study has revealed a new mode of PI3K alteration in primary endometrial tumors and warrants future studies to determine whether PIK3R1 mutations correlate with clinical outcome to targeted therapies directed against the PI3K pathway in EEC and NEEC.

AB PGC-1 alpha is a transcriptional coactivator that powerfully regulates many pathways linked to energy homeostasis. Specifically, PGC-1 alpha controls mitochondrial biogenesis in most tissues but also initiates important tissue-specific functions, including fiber type switching in skeletal muscle and gluconeogenesis and fatty acid oxidation in the liver. We show here that S6 kinase, activated in the liver upon feeding, can phosphorylate PGC-1 alpha directly on two sites within its arginine/serine-rich (RS) domain. This phosphorylation significantly attenuates the ability of PGC-1 alpha to turn on genes of gluconeogenesis in cultured hepatocytes and in vivo, while leaving the functions of PGC-1 alpha as an activator of mitochondrial and fatty acid oxidation genes completely intact. These phosphorylations interfere with the ability of PGC-1 alpha to bind to HNF4 alpha, a transcription factor required for gluconeogenesis, while leaving undisturbed the interactions of PGC-1 alpha with ERR alpha and PPAR alpha, factors important for mitochondrial biogenesis and fatty acid oxidation. These data illustrate that S6 kinase can modify PGC-1 alpha and thus allow molecular dissection of its functions, providing metabolic flexibility needed for dietary adaptation.

AB The discovery of molecules that bind tightly and selectively to desired proteins continues to drive innovation at the interface of chemistry and biology. This paper describes the binding of human insulin by the synthetic receptor cucurbit[7]uril (Q7) in vitro. Isothermal titration calorimetry and fluorescence spectroscopy experiments show that Q7 binds to insulin with an equilibrium association constant of 1.5 x 10(6) M-1 and with 50-100-fold selectivity versus proteins that are much larger but lack an N-terminal aromatic residue, and with >1000-fold selectivity versus an insulin variant lacking the N-terminal phenylalanine (Phe) residue. The crystal structure of the Q7 center dot insulin complex shows that binding occurs at the N-terminal Phe residue and that the N-terminus unfolds to enable binding. These findings suggest that site-selective recognition is based on the properties inherent to a protein terminus, including the unique chemical epitope presented by the terminal residue and the greater freedom of the terminus to unfold, like the end of a ball of string, to accommodate binding. Insulin recognition was predicted accurately from studies on short peptides and exemplifies an approach to protein recognition by targeting the terminus.

AB BACKGROUND: The purpose of this study was to assess the efficacy and safety of 5-fluorouracil (5FU) and gemcitabine administered concurrently with radiation in patients with locally advanced, nonmetastatic pancreatic cancer. METHODS: Eligible patients had histologically confirmed pancreatic adenocarcinoma deemed locally unresectable without evidence of metastatic disease. In addition, all patients underwent laparoscopy or laparotomy before study entry to rule out peritoneal carcinomatosis. Patients received radiation therapy (50.4 Gy) with concurrent infusional 5FU (200 mg/m(2) 5 days/week) and weekly gemcitabine (200 mg/m(2)). After a 3-week break, patients received weekly gemcitabine at 1000 mg/m(2) for 3 of 4 weeks, for 4 cycles. The primary endpoint of the trial was the proportion of patients surviving 9 months from study entry. Secondary endpoints included objective tumor response, CA19-9 response, overall survival (OS) time to progression (TTP), and toxicity. RESULTS: Between November 2001 and October 2004, 81 patients were enrolled, 78 of whom were eligible for analysis. With a median follow-up of 55.2 months, the median OS was 12.2 months (95% confidence interval [CI], 10.9-14.9) and the median TTP was 10 months (95% CI, 6.4-12.0). An objective tumor response was seen in 19 patients (25%), and among 56 patients with an elevated CA19-9 at baseline, 29 (52%) had a sustained CA19-9 response. Overall, 41% of patients had grade 3 or greater treatment-related gastrointestinal adverse events. CONCLUSIONS: The combination of 5FU, gemcitabine, and radiation is well tolerated. Survival is comparable with the best results of other recent studies of 5FU and radiation or gemcitabine and radiation. Cancer 2011; 117: 2620-8. (C) 2010 American Cancer Society.

AB BACKGROUND. The majority of metastatic renal cell carcinoma (mRCC) clinical trials that examined targeted agents used progression-free survival (PFS) as the primary endpoint. Whether PFS can be used as a predictor of overall survival (OS) is unknown. METHODS. Patients from 12 cancer centers who received targeted therapy for mRCC were identified. Landmark analyses for progression at 3 months and 6 months after drug initiation were performed to minimize lead-time bias. A proportional hazards model was used to assess the utility of PFS for predicting OS. RESULTS. In total, 1158 patients were included. The median follow-up was 30.6 months, the median age was 60 years, and the median Karnofsky performance status was 80%. For the entire cohort, the median PFS was 7.6 months, and the median OS was 19.7 months. In the landmark analysis, the median OS for patients who progressed at 3 months was 7.8 months compared with 23.6 months for patients who did not progress (log-rank test; P < .0001). Similarly, for patients who progressed at 6 months, the median OS was 8.6 months compared with 26 months for patients who did not progress (P < .0001). Compared with those who did not progress, for the patients who progressed at 3 months and at 6 months, the hazard ratios for death adjusted for adverse prognostic factors were 3.05 (95% confidence interval, 2.42-3.84) and 2.96 (95% confidence interval, 2.39-3.67), respectively. Similar results were demonstrated with landmark analyses at 9 months and at 12 months and in the bootstrap validation. Kendall tau rank correlation and a Fleischer model demonstrated a statistically significant dependent correlation. CONCLUSIONS. PFS at 3 months and at 6 months predicted OS, and the current results indicated that PFS may be a meaningful intermediate endpoint for OS in patients with mRCC who receive treatment with novel agents.

AB Context Existing evidence of the survival associated with bariatric surgery is based on cohort studies of predominantly younger women with a low inherent obesity-related mortality risk. The association of survival and bariatric surgery for older men is less clear.
Objective To determine whether bariatric surgery is associated with reduced mortality in a multisite cohort of predominantly older male patients who have a high baseline mortality rate.
Design, Setting, and Participants Retrospective cohort study of bariatric surgery programs in Veterans Affairs medical centers. Mortality was examined for 850 veterans who had bariatric surgery in January 2000 to December 2006 (mean age 49.5 years; SD 8.3; mean body mass index [BMI] 47.4; SD 7.8) and 41 244 nonsurgical controls (mean age 54.7 years, SD 10.2; mean BMI 42.0, SD 5.0) from the same 12 Veteran Integrated Service Networks; the mean follow-up was 6.7 years. Four Cox proportional hazards models were assessed: unadjusted and controlled for baseline covariates on unmatched and propensity-matched cohorts.
Main Outcome Measure All-cause mortality through December 2008.
Results Among patients who had bariatric surgery, the 1-, 2-, and 6-year crude mortality rates were, respectively, 1.5%, 2.2%, and 6.8% compared with 2.2%, 4.6%, and 15.2% for nonsurgical controls. In unadjusted Cox regression, bariatric surgery was associated with reduced mortality (hazard ratio [HR], 0.64; 95% confidence interval [CI], 0.51-0.80). After covariate adjustment, bariatric surgery remained associated with reduced mortality (HR, 0.80; 95% CI, 0.63-0.995). In analysis of 1694 propensity-matched patients, bariatric surgery was no longer significantly associated with reduced mortality in unadjusted (HR, 0.83; 95% CI, 0.61-1.14) and time-adjusted (HR, 0.94; 95% CI, 0.64-1.39) Cox regressions.
Conclusion In propensity score-adjusted analyses of older severely obese patients with high baseline mortality in Veterans Affairs medical centers, the use of bariatric surgery compared with usual care was not associated with decreased mortality during a mean 6.7 years of follow-up.

AB Women have consistently demonstrated better verbal memory on tests that evaluate immediate and delayed free recall. In patients with schizophrenia, these verbal memory processes are relatively more preserved in women than men. However an understanding of the brain anatomy of the female advantage for verbal memory is still unclear.
29 females and 59 males with schizophrenia made comparable to 21 female and 27 male healthy volunteers were scanned using structural magnetic resonance imaging (sMRI) in order to assess volumes of regions across the entire brain. Sex differences within and between groups in the covariance structure of memory circuitry regions were evaluated using a novel approach to covariance analysis (the Box M Test). Brain areas of interest included the prefrontal cortex (PFC), inferior parietal lobule (iPAR), anterior cingulate gyrus (ACG), parahippocampus, and hippocampus (HIPP).
Results showed significant differences in the covariance matrices of females and males with schizophrenia compared with their healthy counterparts, in particular the relationships between iPAR-PFC, iPAR-ACG, and HIPP-PFC. Sex differences in the iPAR-PFC relationship were significantly associated with sex differences in verbal memory performance. In control women, but not in men ACG volume correlated strongly with memory performance. In schizophrenia, ACG volume was reduced in females, but not in men, relative to controls.
Findings suggest that the relationship between iPAR and PFC is particularly important for understanding the relative preservation of verbal memory processing in females with schizophrenia and may compensate for ACG volume reductions. These results illustrate the utility of a unique covariance structure modeling approach that yields important new knowledge for understanding the nature of schizophrenia. (C) 2011 Elsevier Inc.

AB Multichannel electroencephalography (EEG) offers a non-invasive tool to explore spatio-temporal dynamics of brain activity. With EEG recordings consisting of multiple trials, traditional signal processing approaches that ignore inter-trial variability in the data may fail to accurately estimate the underlying spatio-temporal brain patterns. Moreover, precise characterization of such inter-trial variability per se can be of high scientific value in establishing the relationship between brain activity and behavior. In this paper, a statistical modeling framework is introduced for learning spatio-temporal decompositions of multiple-trial EEG data recorded under two contrasting experimental conditions. By modeling the variance of source signals as random variables varying across trials, the proposed two-stage hierarchical Bayesian model is able to capture intertrial amplitude variability in the data in a sparse way where a parsimonious representation of the data can be obtained. A variational Bayesian (VB) algorithm is developed for statistical inference of the hierarchical model. The efficacy of the proposed modeling framework is validated with the analysis of both synthetic and real EEG data. In the simulation study we show that even at low signal-to-noise ratios our approach is able to recover with high precision the underlying spatio-temporal patterns and the dynamics of source amplitude across trials; on two brain-computer interface (BCI) data sets we show that our VB algorithm can extract physiologically meaningful spatio-temporal patterns and make more accurate predictions than other two widely used algorithms: the common spatial patterns (CSP) algorithm and the Infomax algorithm for independent component analysis (ICA). The results demonstrate that our statistical modeling framework can serve as a powerful tool for extracting brain patterns, characterizing trial-to-trial brain dynamics, and decoding brain states by exploiting useful structures in the data.

AB Motivation: Most current approaches to high-throughput biological data (HTBD) analysis either perform individual gene/protein analysis or, gene/protein set enrichment analysis for a list of biologically relevant molecules. Bayesian Networks (BNs) capture linear and nonlinear interactions, handle stochastic events accounting for noise, and focus on local interactions, which can be related to causal inference. Here, we describe for the first time an algorithm that models biological pathways as BNs and identifies pathways that best explain given HTBD by scoring fitness of each network.
Results: Proposed method takes into account the connectivity and relatedness between nodes of the pathway through factoring pathway topology in its model. Our simulations using synthetic data demonstrated robustness of our approach. We tested proposed method, Bayesian Pathway Analysis (BPA), on human microarray data regarding renal cell carcinoma (RCC) and compared our results with gene set enrichment analysis. BPA was able to find broader and more specific pathways related to RCC.

AB Functional and structural neuroimaging have identified abnormalities of the brain that are likely to contribute to the neuropathophysiology of attention-deficit/hyperactivity disorder (ADHD). In particular, hypofunction of the brain regions comprising the cingulo-frontal-parietal cognitive-attention network have been consistently observed across studies. These are major components of neural systems that are relevant to ADHD, including cognitive/attention networks, motor systems, and reward/feedback-based processing systems. Moreover, these areas interact with other brain circuits that have been implicated in ADHD, such as the "default mode" resting state network. The ADHD imaging data related to cingulo-frontal-parietal network dysfunction will be selectively highlighted here to help facilitate its integration with the other information presented in this special issue. Together, these reviews will help shed light on the neurobiology of ADHD.

AB Lung transplantation remains the only effective therapy for patients with end-stage pulmonary diseases. Unfortunately, acute rejection of the lung remains a frequent complication and is an important cause of morbidity and mortality. The induction of transplant tolerance is thought to be dependent, in part, on the balance between allograft effector mechanisms mediated by effector T lymphocytes (Teff), and regulatory mechanisms mediated by FOXP3(+) regulatory T cells (Treg). In this study, we explored an approach to tip the balance in favor of regulatory mechanisms by modulating chemokine activity. We demonstrate in an adoptive transfer model of lung rejection that CXCR3-deficient CD8(+) Teff have impaired migration into the lungs compared with wild-type Teff, which results in a dramatic reduction in fatal pulmonary inflammation. The lungs of surviving mice contained tolerized CXCR3-deficient Teff, as well as a large increase in Treg. We confirmed that Treg were needed for tolerance and that their ability to induce tolerance was dependent on their numbers in the lung relative to the numbers of Teff. These data suggest that transplantation tolerance can be achieved by reducing the recruitment of some, but not necessarily all, CD8(+) Teff into the target organ and suggest a novel approach to achieve transplant tolerance.

AB Polyvalent mosaic HIV immunogens offer a potential solution for generating vaccines that can elicit immune responses against genetically diverse viruses. However, it is unclear whether key T cell epitopes can be processed and presented from these synthetic Ags and recognized by epitope-specific human T cells. In this study, we tested the ability of mosaic HIV immunogens expressed by recombinant, replication-incompetent adenovirus serotype 26 vectors to process and present major HIV clade B and clade C CD8 T cell epitopes in human cells. A bivalent mosaic vaccine expressing HIV Gag sequences was used to transduce PBMCs from 12 HIV-1-infected individuals from the United States and 10 HIV-1-infected individuals from South Africa; intracellular cytokine staining, together with tetramer staining, was used to assess the ability of mosaic Gag Ags to stimulate pre-existing memory responses compared with natural clade B and C vectors. Mosaic Gag Ags expressed all eight clade B epitopes tested in 12 United States subjects and all 5 clade C epitopes tested in 10 South African subjects. Overall, the magnitude of cytokine production induced by stimulation with mosaic Ags was comparable to clade B and clade C Ags tested, but the mosaic Ags elicited greater cross-clade recognition. Additionally, mosaic Ags induced HIV-specific CD4 T cell responses. Our studies demonstrate that mosaic Ags express major clade B and clade C viral T cell epitopes in human cells, as well as support the evaluation of mosaic HIV-1 vaccines in humans.

AB Comparative cross-species genomic analysis has served as a powerful tool to discover novel noncoding regulatory regions that influence gene expression in several cytokine loci. In this study, we have identified several evolutionarily conserved regions (ECRs) that are shared between human, rhesus monkey, dog, and horse and that are upstream of the promoter regions that have been previously shown to play a role in regulating CCL2 gene expression. Of these, an ECR that was similar to 16.5 kb (-16.5 ECR) upstream of its coding sequence contained a highly conserved NF-kappa B site. The region encompassing the -16.5 ECR conferred TNF-alpha responsiveness to homologous and heterologous promoters. In vivo footprinting demonstrated that specific nucleotide residues in the -16.5 ECR were protected or became hypersensitive after TNF-alpha treatment. The footprinted regions were found to bind NF-kappa B subunits in vitro and in vivo. Mutation/deletion of the conserved NF-kappa B binding site in the -16.5 ECR led to loss of TNF-alpha responsiveness. After TNF-alpha stimulation, the -16.5 ECR showed increased sensitivity to nuclease digestion and loss of histone signatures that are characteristic of a repressive chromatin. Chromosome conformation capture assays indicated that -16.5 ECR physically interacts with the CCL2 proximal promoter after TNF-alpha stimulation. Taken together, these results suggest that the -16.5 ECR may play a critical role in the regulation of CCL2. The Journal of Immunology, 2011, 186: 7025-7038.

AB IL-10-deficient mice infected with the relapsing fever bacterium Borrelia turicatae rapidly succumb to a brain hemorrhage if they are unable to clear peak bacteremia. In this study, we investigated the protective role of IL-10 during relapsing-remitting bacteremia and explored the molecular events involved in the protection of brain endothelium by IL-10. Brain endothelial injury was measured with cytotoxicity and diverse apoptotic assays, whereas the signaling pathway analysis was done by quantitative PCR array. The results showed that severe endothelial cell injury leading to hemorrhage in the brain and other organs occurred in IL-10-deficient mice during relapsing-remitting infection. Human brain microvascular endothelial cells (HBMEC) produced abundant proinflammatory mediators upon exposure to whole bacteria or purified bacterial lipoprotein but did not produce any detectable IL-10. Whole bacteria and purified outer membrane lipoprotein rapidly killed HBMEC by apoptosis in a time-and concentration-dependent manner. Exogenous IL-10 protected HBMEC from apoptosis. HBMEC apoptosis during exposure to a low number of bacteria was associated with downregulation of TNF and TNFAIP3 and upregulation of BAX. In contrast, HBMEC apoptosis during exposure to high concentrations of purified outer membrane lipoprotein was associated with marked upregulation of FAS, FAS ligand, and the adaptor molecules RIPK1 and CFLAR. Exogenous IL-10 reversed all the apoptotic signaling changes induced by whole bacteria or its purified lipoprotein. The results indicate that prominent brain endothelial cell apoptosis occurs during relapsing-remitting bacteremia in the absence of IL-10 and point to a prominent role for bacterial lipoprotein-mediated activation of FAS and caspase-3 in this process.

AB McLeod syndrome (MIS) is a rare. X-linked, late-onset, disease involving hematological, brain, and neuromuscular systems, caused by mutations in XK that result in either defective XK or complete loss of XK protein. Acanthocytosis of erythrocytes is a typical feature. We report novel mutations in two patients who exhibited typical clinical characteristics of MIS. The coding and flanking intronic regions of XK were amplified by PCR, sequenced, and compared with the normal XK sequence. XK protein, and its complexed partner protein, Kell, were assessed by Western blot analysis. Patient 1 was found to have a single base insertion, 605insA at 175Ile creating a frame shift within the coding sequence of XK. Patient 2 had a single base substitution in the 3' splice sequence of intron 2 (IVS2-2a>g). In both cases mutations resulted in the absence of XK protein. (C) 2011 Elsevier B.V. All rights reserved.

AB The purpose of this study was to identify signalling components known to control mRNA translation initiation in skeletal muscle that are responsive to mechanical load and may be partly responsible for myofibre hypertrophy. To accomplish this, we first utilized a human cluster model in which skeletal muscle samples from subjects with widely divergent hypertrophic responses to resistance training were used for the identification of signalling proteins associated with the degree myofibre hypertrophy. We found that of 11 translational signalling molecules examined, the response of p(T421/S424)-p70S6K phosphorylation and total eukaryotic initiation factor 2B epsilon (eIF2B epsilon) protein abundance after a single bout of unaccustomed resistance exercise was associated with myofibre hypertrophy following 16 weeks of training. Follow up studies revealed that overexpression of eIF2B epsilon alone was sufficient to induce an 87% increase in cap-dependent translation in L6 myoblasts in vitro and 21% hypertrophy of myofibres in mouse skeletal muscle in vivo (P < 0.05). However, genetically altering p70S6K activity had no impact on eIF2B epsilon protein abundance in mouse skeletal muscle in vivo or multiple cell lines in vitro (P > 0.05), suggesting that the two phenomena were not directly related. These are the first data that mechanistically link eIF2B epsilon abundance to skeletal myofibre hypertrophy, and indicate that eIF2B epsilon abundance may at least partially underlie the widely divergent hypertrophic phenotypes in human skeletal muscle exposed to mechanical stimuli.

AB Caveolae form a specialized platform within the plasma membrane that is crucial for an array of important biological functions, ranging from signaling to endocytosis. Using total internal reflection fluorescence (TIRF) and 3D fast spinning-disk confocal imaging to follow caveola dynamics for extended periods, and electron microscopy to obtain high resolution snapshots, we found that the vast majority of caveolae are dynamic with lifetimes ranging from a few seconds to several minutes. Use of these methods revealed a change in the dynamics and localization of caveolae during mitosis. During interphase, the equilibrium between the arrival and departure of caveolae from the cell surface maintains the steady-state distribution of caveolin-1 (Cav1) at the plasma membrane. During mitosis, increased dynamics coupled to an imbalance between the arrival and departure of caveolae from the cell surface induces a redistribution of Cav1 from the plasma membrane to intracellular compartments. These changes are reversed during cytokinesis. The observed redistribution of Cav1 was reproduced by treatment of interphase cells with nocodazole, suggesting that microtubule rearrangements during mitosis can mediate caveolin relocalization. This study provides new insights into the dynamics of caveolae and highlights precise regulation of caveola budding and recycling during mitosis.

AB Background. Recent studies in mice and patients suggest that posttransplantation induction of autoimmune responses to tissue-specific antigens contributes to the rejection of major histocompatibility complex mismatched allotransplants. The relevance of this phenomenon to the rejection of major and minor histocompatibility-mismatched allografts performed in large-animal models remains to be established.
Methods. Miniature swine were immunized with cardiac myosin (CM) in Freund's adjuvant and received heterotopic, minor antigen-mismatched heart transplants. T-cell (proliferation and delayed type hypersensitivity [DTH]) and B-cell (antibody) responses specific to CM were measured. The rejection of heart transplants was assessed histologically.
Results. Three of four swine that were immunized with CM before receiving a minor antigen-mismatched heart transplant exhibited potent DTH, T-cell proliferation and antibody responses to CM and rejected their grafts acutely. The fourth swine, which failed to mount a significant DTH response to CM and displayed low and transient anti-CM antibody titers, demonstrated long-term allograft survival.
Conclusions. This large-animal study supports the relevance of autoimmunity to CM in the rejection of minor antigen disparate cardiac allotransplants.

AB Background. Prolonged cold ischemia (CI) is a risk factor for the development of delayed graft function that predicts reduced 5-year kidney transplant survival. CI results in caspase-3 activation, tubular injury, and apoptosis. Autophagy, a highly conserved pathway that permits recycling of nutrients within the cell during stress, is linked to apoptosis. We hypothesized that CI during kidney preservation would induce autophagy. We sought to determine apoptosis and autophagic flux in CI.
Methods. Autophagic flux and apoptosis were examined in kidneys of wild-type and green fluorescent protein (GFP)-microtubule-associated protein1 light chain 3 (LC3) transgenic mice that were subjected to 48 hr of CI. Autophagic flux was determined by performing experiments with and without bafilomycin A1.
Results. CI alone significantly increased the number of apoptotic cells/hpf, caspase-3/7 activity, and protein expression of autophagy markers LC3 II and autophagy-related protein 5. To determine the effect of inhibiting autophagic flux on apoptosis, kidneys of wild-type and GFP-LC3 transgenic mice were subjected to 48 hr of CI in the presence of lysosomal inhibitor bafilomycin A1. The combination of CI and bafilomycin A1 suppressed autophagic flux and significantly reduced the number of apoptotic cells/hpf, caspase-3/7 activity, LC3 II (both by immunoblot and in GFP-LC3 transgenic mice), and autophagy-related protein 5 protein expression.
Conclusion. In summary, we have shown that autophagy and autophagic flux are reduced in cold ischemic kidneys treated with bafilomycin A1. Reduced autophagy and autophagic flux were associated with a significant reduction in apoptotic cell death, which may provide a therapeutic rationale for including bafilomycin A1 in University of Wisconsin solution during organ preservation.

AB Background. Transmission of human immunodeficiency virus and hepatitis C to transplant recipients has drawn attention of the use of allografts from seronegative donors at increased risk for blood-borne viral infection (DIRVI).
Methods. We performed a cohort study of 7803 kidney transplant recipients whose kidneys were recovered through one of two organ procurement organizations from 1996 to 2007. Detailed organ procurement organization data on donor risk factors were linked to recipient data from the Organ Procurement and Transplantation Network.
Results. Median recipient follow-up was 3.9 years. Three hundred sixty-eight (5%) patients received DIRVI kidneys, a third of which were procured from donors with a history of injection drug use or commercial sex work. Compared with standard criteria kidney recipients, DIRVI kidney recipients were more likely to be human immunodeficiency virus positive or black. In multivariable Cox regression, using DIRVI recipients as the reference, recipients of standard criteria donor kidneys had lower mortality (hazard ratio [HR] 0.71, P < 0.01) and no difference in death-censored allograft failure(HR 1.09, P = 0.62), whereas recipients of expanded criteria donor kidneys had no significant difference in mortality (HR 0.98, P = 0.83) but a higher allograft failure rate (HR 1.93, P < 0.01). High-quality data on posttransplant recipient viral testing were not available.
Conclusions. DIRVI kidney recipients experienced higher mortality than standard criteria kidney recipients. This finding could be explained if sicker patients received DIRVI kidneys (i.e., residual confounding) or the less likely possibility of undetected transmission of viral infections. Given the limitations of registry data used in this analysis, prospective studies are needed to further elucidate these findings.

AB The expanded CAG repeat that causes striatal cell vulnerability in Huntington's disease (HD) encodes a polyglutamine tract in full-length huntingtin that is correlated with cellular [ATP] and [ATP/ADP]. Since striatal neurons are vulnerable to energy deficit, we have investigated, in Hdh CAG knock-in mice and striatal cells, the hypothesis that decreased energetics may affect neuronal (N)-cadherin, a candidate energy-sensitive adhesion protein that may contribute to HD striatal cell sensitivity. In vivo, N-cadherin was sensitive to ischemia and to the effects of full-length mutant huntingtin, progressively decreasing in Hdh(Q111) striatum with age. In cultured striatal cells, N-cadherin was decreased by ATP depletion and ST Hdh(Q111) striatal cells exhibited dramatically decreased N-cadherin, due to decreased Cdh2 mRNA and enhanced N-cadherin turnover, which was partially normalized by adenine supplementation to increase [ATP] and [ATP/ADP]. Consistent with decreased N-cadherin function, ST Hdh(Q111) striatal cells displayed profound deficits in calcium-dependent N-cadherin-mediated cell clustering and cell-substratum adhesion, and primary Hdh(Q111) striatal neuronal cells exhibited decreased N-cadherin and an abundance of immature neurites, featuring diffuse, rather than clustered, staining for N-cadherin and synaptic vesicle markers, which was partially rescued by adenine treatment. Thus, mutant full-length huntingtin, via energetic deficit, contributes to decreased N-cadherin levels in striatal neurons, with detrimental effects on neurite maturation, strongly suggesting that N-cadherin-mediated signaling merits investigation early in the HD pathogenic disease process.

AB Polymorphisms in the MYH9 and adjacent APOL1 gene region demonstrate a strong association with nondiabetic kidney disease in African-Americans. However, it is not known to what extent these polymorphisms are present in other ethnic groups. To examine the association of genetic polymorphisms in this region with chronic kidney disease (CKD; estimated glomerular filtration rate <60 ml/min/1.73 m(2)) in individuals of European ancestry, we examined rs4821480, an MYH9 single-nucleotide polymorphism (SNP) recently identified as associated with kidney disease in African-Americans, in 13 133 participants from the Framingham Heart Study (FHS) and Atherosclerosis Risk in Communities (ARIC) Study. In addition, we further interrogated the MYH9/APOL1 gene region using 282 SNPs for association with CKD using age-, sex- and center-adjusted models and performed a meta-analysis of the results from both studies. Because of prior data linking rs4821480 and kidney disease, we used a P-value of <0.05 to test the association with CKD. In the meta-analysis, rs4821480 (minor allele frequency 4.45 and 3.96% in FHS and ARIC, respectively) was associated with higher CKD prevalence in participants free of diabetes (odds ratio 1.44; 95% confidence interval 1.15-1.80; P = 0.001). No other SNPs achieved significance after adjusting for multiple testing. Results utilizing directly genotyped data confirmed the results of the primary analysis. Recently identified APOL1 risk variants were also directly genotyped, but did not account for the observed MYH9 signal. These data suggest that the MYH9 polymorphism rs4821480 is associated with an increased risk of non-diabetic CKD in individuals of European ancestry.

AB We developed and validated a rapid, sensitive, and specific liquid chromatography tandem mass spectrometry (LC-MS/MS) method for determination of global DNA methylation in tissue. DNA was extracted by phenol-chloroform, hydrolyzed using 88% formic acid at 140 degrees C, spiked with cytosine-2,4-(CN2)-C-13-N-15 as internal standard, evaporated under nitrogen, reconstituted in methanol, and analyzed by LC-MS/MS in multiple reaction monitoring mode to reflect the global DNA methylation of the tissue. The method was linear throughout the range of clinical interest and had good sensitivity, with a limit of quantification of 0.5 pg for both cytosine (Cyt) and 5-methylcytosine (5mCyt). The linear range of calibration curve was 1-50 and 1-100 ng/ml for 5mCyt and Cyt, respectively, with a correlation coefficient higher than 0.99. The relative standard deviation (RSD) was 0.70-4.09% and 0.60-4.81% for Cyt and 5mCyt, respectively. The intraday precision expressed as RSD ranged from 1.86% to 4.67%, whereas the interday values ranged from 3.72% to 4.68%. The recovery of the method varied from 86.52% to 105.14%. This yielded a simple and reliable LC-MS/MS assay for detection of Cyt and 5mCyt, thereby enabling the evaluation of global DNA methylation. (C) 2011 Elsevier Inc. All rights reserved.

AB Germline mutations of FH, the gene that encodes for the tricarboxylic acid TCA (TCA) cycle enzyme fumarate hydratase, are associated with an inherited form of cancer referred to as Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC). Individuals with HLRCC are predisposed to the development of highly malignant and lethal renal cell carcinoma (RCC). The mechanisms of tumorigenesis proposed have largely focused on the biochemical consequences of loss of FH enzymatic activity. While loss of the tumor suppressor gene von Hippel Lindau (VHL) is thought to be an initiating event for the majority of RCCs, a role for FH in sporadic renal cancer has not been explored. Here we report that FH mRNA and protein expression are reduced in clear cell renal cancer, the most common histologic variant of kidney cancer. Moreover, we demonstrate that reduced FH leads to the accumulation of hypoxia inducible factor-2 alpha (HIF-2 alpha), a transcription factor known to promote renal carcinogenesis. Finally, we demonstrate that overexpression of FH in renal cancer cells inhibits cellular migration and invasion. These data provide novel insights into the tumor suppressor functions of FH in sporadic kidney cancer.

AB Background-The balance between benefit (ischemia protection) and risk (bleeding) is a key consideration in choosing the intensity of antiplatelet therapy for patients with acute coronary syndromes. The goals of this analysis were to identify baseline characteristics that independently predict bleeding and to determine how bleeding events impact the subsequent mortality in the Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition With Prasugrel-Thrombolysis in Myocardial Infarction 38 (TRITON-TIMI 38).
Methods and Results-Multivariable Cox regression analyses adjusted for treatment, baseline, and procedural variables were used to determine the predictors for serious (TIMI major or minor) bleeding. To analyze the hazard ratio and time dependency of bleeding on mortality, we used iterative day-to-day landmark analyses after the bleed. From the 13 420 patients with acute coronary syndromes included in this analysis, 534 (4.0%) experienced a serious bleeding event. Variables with the highest strength of association with risk of serious bleeding were female sex, use of a glycoprotein IIb/IIIa inhibitor, duration of intervention, age, assignment to prasugrel, regional characteristics, admission diagnosis of ST-elevation myocardial infarction, femoral access for angiography, creatinine clearance, hypercholesterolemia, and arterial hypertension. Serious bleeding was associated with a significantly increased adjusted hazard ratio of 5.84 (95% confidence interval 4.11 to 8.29) for mortality. However, the hazard ratio did not differ statistically from baseline risk by 40 days after the bleeding event.
Conclusions-The major predictors of serious bleeding were a combination of patient and procedural characteristics and antiplatelet therapies. Although serious bleeding was strongly associated with mortality within the first month of the bleeding event, this association was not significant beyond 40 days.

AB Objectives The purpose of this study was to assess whether: 1) very small increases in troponin T, measured by a new highly sensitive cardiac troponin T (hs-cTnT), may reflect ischemia without necrosis; and 2) serial changes can discriminate ischemia from other causes of cardiac troponin T (cTnT) release.
Background A new hs-cTnT assay offers greater sensitivity than current assays.
Methods Nineteen patients referred for diagnostic catheterization underwent cannulation of the coronary sinus (CS). Serial CS and peripheral plasma samples were obtained at multiple time points during and after incremental rapid atrial pacing. cTnT was quantified using both a standard and a pre-commercial highly sensitive assay. Ischemia was determined by the presence of significant coronary artery disease (CAD) and myocardial lactate release with pacing.
Results cTnT concentrations in CS blood increased from a median of 6.8 pg/ml prior to pacing to 15.6 pg/ml 60 min after termination of rapid atrial pacing (p < 0.0001), changes that were mirrored at 180 min in peripheral blood (5.1 to 11.8 pg/ml, p < 0.0001). Although peripheral cTnT concentrations tended to be higher at 180 min following pacing for patients with CAD and lactate elution (n = 7) when compared with those without either marker (n = 5) (25.0 pg/ml vs. 10.2 pg/ml, p = 0.10), relative (1.7-fold vs. 5.2-fold) and absolute (6.8 pg/ml vs. 8.8 pg/ml, p = 0.50) changes were not different between groups.
Conclusions Brief periods of ischemia, without frank infarction, cause low-level cTnT release, and small increases are common after periods of increased myocardial work, even among patients without objective evidence of myocardial ischemia or obstructive CAD. Additional research is needed before hs-cTnT assays are widely adopted in the management of subjects with chest pain syndromes.

AB Objectives We conducted a systematic review and meta-analysis to determine the predictive value of findings of coronary computed tomography angiography for incident cardiovascular events.
Background Initial studies indicate a prognostic value of the technique; however, the level of evidence as well as exact independent risk estimates remain unclear.
Methods We searched PubMed, EMBASE, and the Cochrane Library through January 2010 for studies that followed up >= 100 subjects for >1 year and reported at >1 hazard ratio (HR) of interest. Risk estimates for the presence of significant coronary stenosis (primary endpoint; >= 50% diameter stenosis), left main coronary artery stenosis, each coronary stenosis, 3-vessel disease, any plaque, per coronary segment containing plaque, and noncalcified plaque were derived in random effect regression analysis, and causes of heterogeneity were determined in meta-regression analysis.
Results We identified 11 eligible articles including 7,335 participants (age 59.1 +/- 2.6 years, 62.8% male) with suspected coronary artery disease. The presence of >= 1 significant coronary stenosis (9 studies, 3,670 participants, and 252 outcome events [6.8%] with 62% revascularizations) was associated with an annualized event rate of 11.9% (6.4% in studies excluding revascularization). The corresponding HR was 10.74 (98% confidence interval [CI]: 6.37 to 18.11) and 6.15 (95% CI: 3.22 to 11.74) in studies excluding revascularization. Adjustment for coronary calcification did not attenuate the prognostic significance (p = 0.79). The estimated HRs for left main stenosis, presence of plaque, and each coronary segment containing plaque were 6.64 (95% CI: 2.6 to 17.3), 4.51 (95% CI: 2.2 to 9.3), and 1.23 (95% CI: 1.17 to 1.29), respectively.
Conclusions Presence and extent of coronary artery disease on coronary computed tomography angiography are strong, independent predictors of cardiovascular events despite heterogeneity in endpoints, categorization of computed tomography findings, and study population.

AB The anaphase-promoting complex/cyclosome (APC/C) is a cell cycle-regulated E3 ubiquitin ligase that controls the degradation of substrate proteins at mitotic exit and throughout the G1 phase. We have identified an APC/C substrate and cell cycle-regulated protein, KIAA0101/PAF15. PAF15 protein levels peak in the G2/M phase of the cell cycle and drop rapidly at mitotic exit in an APC/C- and KEN-box-dependent fashion. PAF15 associates with proliferating cell nuclear antigen (PCNA), and depletion of PAF15 decreases the number of cells in S phase, suggesting a role for it in cell cycle regulation. Following irradiation, PAF15 colocalized with gamma H2AX foci at sites of DNA damage through its interaction with PCNA. Finally, PAF15 depletion led to an increase in homologous recombination-mediated DNA repair, and overexpression caused sensitivity to UV-induced DNA damage. We conclude that PAF15 is an APC/C-regulated protein involved in both cell cycle progression and the DNA damage response.

AB Pancreatic neuroendocrine tumors (NET) have diverse clinical presentations. Patients with symptoms of hormone secretion may require specific medical interventions to control those symptoms prior to antitumor intervention. In some patients, tumors in the pancreas may be occult and specialized diagnostic imaging or surgery may be required for diagnosis. Other patients may present with more advanced disease, presenting with symptoms of tumor bulk rather than hormone secretion. Treatment options for patients with advanced pancreatic neuroendocrine tumors include surgical resection and hepatic directed therapies, including partial hepatectomy, hepatic artery embolization, or other ablative techniques. Streptozocin or temozolomide-based chemotherapy regimens are active against pancreatic NET, and can also play an important role in the palliation of patients with advanced disease. A number of biologically targeted agents targeting the VEGF and mTOR signaling pathways have recently shown promise, with recent trials showing treatment with the VEGFR tyrosine kinase inhibitor sunitinib or the mTOR inhibitor everolimus improves progression-free survival in patients with advanced NET.

AB Mild uncoupling of oxidative phosphorylation has been reported to reduce generation of reactive oxygen species (ROS) and therefore may be neuroprotective. We reported previously that the mitochondrial poison rotenone enhanced currents evoked by N-methyl-D-aspartate (NMDA) by a ROS-dependent mechanism in rat midbrain dopamine neurons. Thus, rotenone, which produces a model of Parkinson's disease in rodents, may increase the risk of dopamine neuron excitotoxicity. The purpose of this study was to test the hypothesis that oxidative phosphorylation uncoupling agents would antagonize the effect of rotenone on NMDA current. We used patch pipettes to record whole-cell currents under voltage-clamp (-60 mV) in substantia nigra dopamine neurons in slices of rat brain. Rotenone, NMDA and uncoupling agents were added to the brain slice superfusate. Inward currents evoked by NMDA (30 mu M) more than doubled in amplitude after slices were superfused for 30 min with 100 nM rotenone. Continuous superfusion with the uncoupling agent carbonyl cyanide-p-trifluoromethoxy-phenylhydrazone (1-3 nM) or 2,4-dinitrophenol (100 nM) significantly antagonized and delayed the ability of rotenone to potentiate NMDA currents. Coenzyme Q(10) (1-10 nM), which has been reported to facilitate uncoupling protein activity, also antagonized this action of rotenone. These results suggest that mild uncoupling of oxidative phosphorylation may protect dopamine neurons against injury from mitochondrial poisons such as rotenone. Published by Elsevier B.V.

From one established human MPNST cell line, S462, cells meeting the criteria for cancer stem cells were isolated. Clonal spheres were obtained, which could be passaged multiple times. Enrichment of stem cell-like cells in these spheres was also supported by increased expression of stem cell markers such as CD133, Oct4, Nestin and NGFR, and decreased expression of mature cell markers such as CD90 and NCAM. Furthermore, cells of these clonal S462 spheres differentiated into Schwann cells, smooth muscle/fibroblast and neurons-like cells under specific differentiation-inducing cultural conditions. Finally, subcutaneous injection of the spheres into immunodeficient nude mice led to tumor formation at a higher rate compared to the parental adherent cells (66% versus 10% at 2.5x10(5)). These results provide evidence for the existence of cancer stem cell-like cells in malignant peripheral nerve sheath tumors.

AB Reciprocating drug delivery is a means of delivering soluble drugs directly to closed fluid spaces in the body via a single cannula without an accompanying fluid volume change. It is ideally suited for drug delivery into small, sensitive and unique fluid spaces such as the cochlea. We characterized the pharmacokinetics of reciprocating drug delivery to the scala tympani within the cochlea by measuring the effects of changes in flow parameters on the distribution of drug throughout the length of the cochlea. Distribution was assessed by monitoring the effects of DNQX, a reversible glutamate receptor blocker, delivered directly to the inner ear of guinea pigs using reciprocating flow profiles. We then modeled the effects of those parameters on distribution using both an iterative curve-fitting approach and a computational fluid dynamic model. Our findings are consistent with the hypothesis that reciprocating delivery distributes the drug into a volume in the base of the cochlea, and suggest that the primary determinant of distribution throughout more distal regions of the cochlea is diffusion. Increases in flow rate distributed the drug into a larger volume that extended more apically. Over short time courses (less than 2 h), the apical extension, though small, significantly enhanced apically directed delivery of drug. Over longer time courses (>5 h) or greater distances (>3 mm), maintenance of drug concentration in the basal scala tympani may prove more advantageous for extending apical delivery than increases in flow rate. These observations demonstrate that this reciprocating technology is capable of providing controlled delivery kinetics to the closed fluid space in the cochlea, and may be suitable for other applications such as localized brain and retinal delivery.

AB Rare variants affecting phenotype pose a unique challenge for human genetics. Although genome-wide association studies have successfully detected many common causal variants, they are underpowered in identifying disease variants that are too rare or population-specific to be imputed from a general reference panel and thus are poorly represented on commercial SNP arrays. We set out to overcome these challenges and detect association between disease and rare alleles using SNP arrays by relying on long stretches of genomic sharing that are identical by descent. We have developed an algorithm, DASH, which builds upon pairwise identical-by-descent shared segments to infer clusters of individuals likely to be sharing a single haplotype. DASH constructs a graph with nodes representing individuals and links on the basis of such segments spanning a locus and uses an iterative minimum cut algorithm to identify densely connected components. We have applied DASH to simulated data and diverse GWAS data sets by constructing haplotype clusters and testing them for association. In simulations we show this approach to be significantly more powerful than single-marker testing in an isolated population that is from Kosrae, Federated States of Micronesia and has abundant IBD, and we provide orthogonal information for rare, recent variants in the outbred Wellcome Trust Case-Control Consortium (WTCCC) data. In both cohorts, we identified a number of haplotype associations, five such loci in the WTCCC data and ten in the isolated, that were conditionally significant beyond any individual nearby markers. We have replicated one of these loci in an independent European cohort and identified putative structural changes in low-pass whole-genome sequence of the cluster carriers.

AB Epigenetic regulation of gene expression by histone-modifying corepressor complexes is central to normal animal development. The NAD+-dependent deacetylase and gene repressor SIRT1 removes histone H4K16 acetylation marks and facilitates heterochromatin formation. However, the mechanistic contribution of SIRT1 to epigenetic regulation at euchromatic loci and whether it acts in concert with other chromatin-modifying activities to control developmental gene expression programs remain unclear. We describe here a SIRT1 corepressor complex containing the histone H3K4 demethylase LSD1/KDM1A and several other LSD1-associated proteins. SIRT1 and LSD1 interact directly and play conserved and concerted roles in H4K16 deacetylation and H3K4 demethylation to repress genes regulated by the Notch signaling pathway. Mutations in Drosophila SIRT1 and LSD1 orthologs result in similar developmental phenotypes and genetically interact with the Notch pathway in Drosophila. These findings offer new insights into conserved mechanisms of epigenetic gene repression and regulation of development by SIRT1 in metazoans.

AB The pluripotent state of embryonic stem cells (ESCs) provides a unique perspective on regulatory programs that govern self-renewal and differentiation and somatic cell reprogramming. Here, we review the highly connected protein and transcriptional networks that maintain pluripotency and how they are intertwined with factors that affect chromatin structure and function. The complex interrelationships between pluripotency and chromatin factors are illustrated by X chromosome inactivation, regulatory control by noncoding RNAs, and environmental influences on cell states. Manipulation of cell state through the process of transdifferentiation suggests that environmental cues may direct transcriptional programs as cells enter a transiently "plastic" state during reprogramming.

AB Melanocyte stem cells (McSCs) intimately interact with epithelial stem cells (EpSCs) in the hair follicle bulge and secondary hair germ (sHG). Together, they undergo activation and differentiation to regenerate pigmented hair. However, the mechanisms behind this coordinated stem cell behavior have not been elucidated. Here, we identified Wnt signaling as a key pathway that couples the behavior of the two stem cells. EpSCs and McSCs coordinately activate Wnt signaling at the onset of hair follicle regeneration within the sHG. Using genetic mouse models that specifically target either EpSCs or McSCs, we show that Wnt activation in McSCs drives their differentiation into pigment-producing melanocytes, while EpSC Wnt signaling not only dictates hair follicle formation but also regulates McSC proliferation during hair regeneration. Our data define a role for Wnt signaling in the regulation of McSCs and also illustrate a mechanism for regeneration of complex organs through collaboration between heterotypic stem cell populations.

AB Purpose
Technical studies suggest that computed tomography (CT) - based simulation improves the therapeutic ratio for thoracic radiation therapy (TRT), although few studies have evaluated its use or impact on outcomes.
Methods
We used the Surveillance, Epidemiology and End Results (SEER) - Medicare linked data to identify CT-based simulation for TRT among Medicare beneficiaries diagnosed with stage III non-small-cell lung cancer (NSCLC) between 2000 and 2005. Demographic and clinical factors associated with use of CT simulation were identified, and the impact of CT simulation on survival was analyzed by using Cox models and propensity score analysis.
Results
The proportion of patients treated with TRT who had CT simulation increased from 2.4% in 1994 to 34.0% in 2000 to 77.6% in 2005. Of the 5,540 patients treated with TRT from 2000 to 2005, 60.1% had CT simulation. Geographic variation was seen in rates of CT simulation, with lower rates in rural areas and in the South and West compared with those in the Northeast and Midwest. Patients treated with chemotherapy were more likely to have CT simulation (65.2% v 51.2%; adjusted odds ratio, 1.67; 95% CI, 1.48 to 1.88; P < .01), although there was no significant association between use of surgery and CT simulation. Controlling for demographic and clinical characteristics, CT simulation was associated with lower risk of death (adjusted hazard ratio, 0.77; 95% CI, 0.73 to 0.82; P < .01) compared with conventional simulation.
Conclusion
CT-based simulation has been widely, although not uniformly, adopted for the treatment of stage III NSCLC and is associated with higher survival among patients receiving TRT. J Clin Oncol 29: 2305-2311. (C) 2011 by American Society of Clinical Oncology

AB Purpose
Understanding of prognosis among terminally ill patients impacts medical decision making. The aims of this study were to explore perceptions of prognosis and goals of therapy in patients with metastatic non-small-cell lung cancer (NSCLC) and to examine the effect of early palliative care on these views over time.
Patients and Methods
Patients with newly diagnosed metastatic NSCLC were randomly assigned to receive either early palliative care integrated with standard oncology care or standard oncology care alone. Participants completed baseline and longitudinal assessments of their perceptions of prognosis and the goals of cancer therapy over a 6-month period.
Results
We enrolled 151 participants on the study. Despite having terminal cancer, one third of patients (46 of 145 patients) reported that their cancer was curable at baseline, and a majority (86 of 124 patients) endorsed getting rid of all of the cancer as a goal of therapy. Baseline perceptions of prognosis (ie, curability) and goals of therapy did not differ significantly between study arms. A greater percentage of patients assigned to early palliative care retained or developed an accurate assessment of their prognosis over time (82.5% v 59.6%; P = .02) compared with those receiving standard care. Patients receiving early palliative care who reported an accurate perception of their prognosis were less likely to receive intravenous chemotherapy near the end of life (9.4% v 50%; P = .02).
Conclusion
Many patients with newly diagnosed metastatic NSCLC hold inaccurate perceptions of their prognoses. Early palliative care significantly improves patient understanding of prognosis over time, which may impact decision making about care near the end of life. J Clin Oncol 29: 2319- 2326.

1,25-DIHYDROXYVITAMIN-D; D-3
AB Purpose
Data suggest that circulating 25-hydroxyvitamin D [25(OH)D] interacts with the vitamin D receptor (VDR) to decrease proliferation and increase apoptosis for some malignancies, although evidence for prostate cancer is less clear. How VDR expression in tumor tissue may influence prostate cancer progression has not been evaluated in large studies.
Patients and Methods
We examined protein expression of VDR in tumor tissue among 841 patients with prostate cancer in relation to risk of lethal prostate cancer within two prospective cohorts, the Physicians' Health Study and Health Professionals Follow-Up Study. We also examined the association of VDR expression with prediagnostic circulating 25(OH) D and 1,25-dihydroxyvitamin D levels and with two VDR single nucleotide polymorphisms, FokI and BsmI.
Results
Men whose tumors had high VDR expression had significantly lower prostate-specific antigen (PSA) at diagnosis (P for trend < .001), lower Gleason score (P for trend < .001), and less advanced tumor stage (P for trend < .001) and were more likely to have tumors harboring the TMPRSS2:ERG fusion (P for trend = .009). Compared with the lowest quartile, men whose tumors had the highest VDR expression had significantly reduced risk of lethal prostate cancer (hazard ratio [HR], 0.17; 95% CI, 0.07 to 0.41). This association was only slightly attenuated after adjustment for Gleason score and PSA at diagnosis (HR, 0.33; 95% CI, 0.13 to 0.83) or, additionally, for tumor stage (HR, 0.37; 95% CI, 0.14 to 0.94). Neither prediagnostic plasma vitamin D levels nor VDR polymorphisms were associated with VDR expression.
Conclusion
High VDR expression in prostate tumors is associated with a reduced risk of lethal cancer, suggesting a role of the vitamin D pathway in prostate cancer progression. J Clin Oncol 29:2378-2385. (C) 2011 by American Society of Clinical Oncology

TI mRNA Expression Signature of Gleason Grade Predicts Lethal Prostate
Cancer
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID POPULATION-BASED COHORT; GENE-EXPRESSION; PROGNOSTIC-SIGNIFICANCE;
PROGRESSION; SCORE; CARCINOMA; DISEASE; TISSUES; DEATH
AB Purpose
Prostate-specific antigen screening has led to enormous overtreatment of prostate cancer because of the inability to distinguish potentially lethal disease at diagnosis. We reasoned that by identifying an mRNA signature of Gleason grade, the best predictor of prognosis, we could improve prediction of lethal disease among men with moderate Gleason 7 tumors, the most common grade, and the most indeterminate in terms of prognosis.
Patients and Methods
Using the complementary DNA-mediated annealing, selection, extension, and ligation assay, we measured the mRNA expression of 6,100 genes in prostate tumor tissue in the Swedish Watchful Waiting cohort (n = 358) and Physicians' Health Study (PHS; n = 109). We developed an mRNA signature of Gleason grade comparing individuals with Gleason <= 6 to those with Gleason >= 8 tumors and applied the model among patients with Gleason 7 to discriminate lethal cases.
Results
We built a 157-gene signature using the Swedish data that predicted Gleason with low misclassification (area under the curve [AUC] = 0.91); when this signature was tested in the PHS, the discriminatory ability remained high (AUC = 0.94). In men with Gleason 7 tumors, who were excluded from the model building, the signature significantly improved the prediction of lethal disease beyond knowing whether the Gleason score was 4 + 3 or 3 + 4 (P = .006).
Conclusion
Our expression signature and the genes identified may improve our understanding of the de-differentiation process of prostate tumors. Additionally, the signature may have clinical applications among men with Gleason 7, by further estimating their risk of lethal prostate cancer and thereby guiding therapy decisions to improve outcomes and reduce overtreatment.

AB Purpose
Cisplatin-based combination chemotherapy is considered standard first-line treatment for patients with metastatic urothelial carcinoma. However, a large proportion of patients with metastatic urothelial carcinoma are considered "unfit" for cisplatin. The purpose of this review is to define unfit patients and to identify treatment options for this subgroup of patients.
Patients and Methods
In this review, the criteria used to define unfit patients are explored and the results of prospective clinical trials evaluating chemotherapeutic regimens in unfit patients are summarized.
Results
Several phase II trials and a single, large phase III trial have explored chemotherapeutic regimens for the treatment of unfit patients with metastatic urothelial carcinoma. Heterogeneous eligibility criteria have been used to define unfit patients in these studies. A uniform definition of unfit is proposed on the basis of the results of a survey of genitourinary medical oncologists. According to this definition, unfit patients would meet at least one of the following criteria: Eastern Cooperative Oncology Group performance status of 2, creatinine clearance less than 60 mL/min, grade >= 2 hearing loss, grade >= 2 neuropathy, and/or New York Heart Association Class III heart failure.
Conclusion
Additional studies to optimize treatment for this important subset of patients are needed. A uniform definition of unfit patients will lead to more uniform clinical trials, enhanced ability to interpret the results of these trials, and a greater likelihood of developing a viable strategy for regulatory approval.

AB Tetracycline antibiotics, including doxycycli\e (DOX), have been used to treat bone resorptive diseases, partially because of their activity to suppress osteoclastogenesis induced by receptor activator of nuclear factor kappa B ligand (RANKL). However, their precise inhibitory mechanism remains unclear. Therefore, the present study examined the effect of Dox on osteoclastogenesis signaling induced by RANKL, both in vitro and in vivo. Although Dox inhibited RANKL-induced osteoclastogenesis and down-modulated the mRNA expression, of functional osteoclast markers, including tartrate-resistant acid phosphatase (TRAP) and cathepsin K. Dox neither affected RANKL-induced MAPKs phosphorylation nor NFATc1 gene expression in RAW264.7 murine monocytic cells. Gelatin zymography and Western blot analyses showed that Dox down-regulated the enzyme activity of RANKL-induced MMP-9, but without affecting its protein expression. Furthermore, MMP-9 enzyme inhibitor also attenuated both RANKL-induced osteoclastogenesis and up-regulation of TRAP and cathepsin K mRNA expression, indicating that MMP-9 enzyme action is engaged in the promotion of RANKL-induced osteoclastogenesis. Finally, Dox treatment abrogated RANKL-induced osteoclastogenesis and TRAP activity in mouse calvaria along with the suppression of MMP9 enzyme activity, again without affecting the expression of MMP9 protein. These findings suggested that Dox inhibits RANKL-induced osteoclastogenesis by its inhibitory effect on MMP-9 enzyme activity independent of the MAPK-NFATc1 signaling cascade. (C) 2011 Elsevier Inc.

AB Photoreactive derivatives of the general anesthetic etomidate have been developed to identify their binding sites in gamma-aminobutyric acid, type A and nicotinic acetylcholine receptors. One such drug, [(3)H]TDBzl-etomidate (4-[3-(trifluoromethyl)3H-diazirin-3-yl]benzyl-[(3)H]1-(1-phenylethyl)-1H-imidazole-5- carboxylate), acts as a positive allosteric potentiator of Torpedo nACh receptor (nAChR) and binds to a novel site in the transmembrane domain at the gamma-alpha subunit interface. To extend our understanding of the locations of allosteric modulator binding sites in the nAChR, we now characterize the interactions of a second aryl diazirine etomidate derivative, TFD-etomidate (ethyl-1-(1-(4-(3-trifluoromethyl)-3H-diazirin-3-yl)phenylethyl)1H-imidazole-5-carboxylate). TFD-etomidate inhibited acetylcholine-induced currents with an IC(50) = 4 mu M, whereas it inhibited the binding of [(3)H]phencyclidine to the Torpedo nAChR ion channel in the resting and desensitized states with IC(50) values of 2.5 and 0.7 mM, respectively. Similar to [(3)H] TDBzl-etomidate, [(3)H]TFD-etomidate bound to a site at the gamma-alpha subunit interface, photolabeling alpha M2-10 (alpha Ser-252) and gamma Met-295 and gamma Met-299 within gamma M3, and to a site in the ion channel, photolabeling amino acids within each subunit M2 helix that line the lumen of the ion channel. In addition, [(3)H]TFD-etomidate photolabeled in an agonist-dependent manner amino acids within the delta subunit M2-M3 loop (delta Ile-288) and the delta subunit transmembrane helix bundle (delta Phe-232 and delta Cys-236 within delta M1). The fact that TFD-etomidate does not compete with ion channel blockers at concentrations that inhibit acetylcholine responses indicates that binding to sites at the gamma-alpha subunit interface and/or within delta subunit helix bundle mediates the TFD-etomidate inhibitory effect. These results also suggest that the gamma-alpha subunit interface is a binding site for Torpedo nAChR negative allosteric modulators (TFD-etomidate) and for positive modulators (TDBzl-etomidate).

AB HIV-1 integrase (IN) orchestrates the integration of the reverse transcribed viral cDNA into the host cell genome and participates also in other steps of HIV-1 replication. Cellular and viral factors assist IN in performing its multiple functions, and post-translational modifications contribute to modulate its activities. Here, we show that HIV-1 IN is modified by SUMO proteins and that phylogenetically conserved SUMOylation consensus motifs represent major SUMO acceptor sites. Viruses harboring SUMOylation site IN mutants displayed a replication defect that was mapped during the early stages of infection, before integration but after reverse transcription. Because SUMOylation-defective IN mutants retained WT catalytic activity, we hypothesize that SUMOylation might regulate the affinity of IN for co-factors, contributing to efficient HIV-1 replication.

AB The mammalian target of rapamycin (mTOR) protein kinase is a master growth promoter that nucleates two complexes, mTORC1 and mTORC2. Despite the diverse processes controlled by mTOR, few substrates are known. We defined the mTOR-regulated phosphoproteome by quantitative mass spectrometry and characterized the primary sequence motif specificity of mTOR using positional scanning peptide libraries. We found that the phosphorylation response to insulin is largely mTOR dependent and that mTOR exhibits a unique preference for proline, hydrophobic, and aromatic residues at the +1 position. The adaptor protein Grb10 was identified as an mTORC1 substrate that mediates the inhibition of phosphoinositide 3-kinase typical of cells lacking tuberous sclerosis complex 2 (TSC2), a tumor suppressor and negative regulator of mTORC1. Our work clarifies how mTORC1 inhibits growth factor signaling and opens new areas of investigation in mTOR biology.

AB Background: In comparison to other bacterial pathogens, our knowledge of the molecular basis of the pathogenesis of leptospirosis is extremely limited. An improved understanding of leptospiral pathogenetic mechanisms requires reliable tools for functional genetic analysis. Leptospiral immunoglobulin-like (Lig) proteins are surface proteins found in pathogenic Leptospira, but not in saprophytes. Here, we describe a system for heterologous expression of the Leptospira interrogans genes ligA and ligB in the saprophyte Leptospira biflexa serovar Patoc.
Results: The genes encoding LigA and LigB under the control of a constitutive spirochaetal promoter were inserted into the L. biflexa replicative plasmid. We were able to demonstrate expression and surface localization of LigA and LigB in L. biflexa. We found that the expression of the lig genes significantly enhanced the ability of transformed L. biflexa to adhere in vitro to extracellular matrix components and cultured cells, suggesting the involvement of Lig proteins in cell adhesion.
Conclusions: This work reports a complete description of the system we have developed for heterologous expression of pathogen-specific proteins in the saprophytic L. biflexa. We show that expression of LigA and LigB proteins from the pathogen confers a virulence-associated phenotype on L. biflexa, namely adhesion to eukaryotic cells and fibronectin in vitro. This study indicates that L. biflexa can serve as a surrogate host to characterize the role of key virulence factors of the causative agent of leptospirosis.

AB Cyclin D1 is a component of the core cell cycle machinery(1). Abnormally high levels of cyclin D1 are detected in many human cancer types(2). To elucidate the molecular functions of cyclin D1 in human cancers, we performed a proteomic screen for cyclin D1 protein partners in several types of human tumours. Analyses of cyclin D1 interactors revealed a network of DNA repair proteins, including RAD51, a recombinase that drives the homologous recombination process(3). We found that cyclin D1 directly binds RAD51, and that cyclin D1-RAD51 interaction is induced by radiation. Like RAD51, cyclin D1 is recruited to DNA damage sites in a BRCA2-dependent fashion. Reduction of cyclin D1 levels in human cancer cells impaired recruitment of RAD51 to damaged DNA, impeded the homologous recombination-mediated DNA repair, and increased sensitivity of cells to radiation in vitro and in vivo. This effect was seen in cancer cells lacking the retinoblastoma protein, which do not require D-cyclins for proliferation(4,5). These findings reveal an unexpected function of a core cell cycle protein in DNA repair and suggest that targeting cyclin D1 may be beneficial also in retinoblastoma-negative cancers which are currently thought to be unaffected by cyclin D1 inhibition.

AB We have undertaken a genome-wide analysis of rare copy-number variation (CNV) in 1124 autism spectrum disorder (ASD) families, each comprised of a single proband, unaffected parents, and, in most kindreds, an unaffected sibling. We find significant association of ASD with de novo duplications of 7q11.23, where the reciprocal deletion causes Williams-Beuren syndrome, characterized by a highly social personality. We identify rare recurrent de novo CNVs at five additional regions, including 16p13.2 (encompassing genes USP7 and C16orf72) and Cadherin 13, and implement a rigorous approach to evaluating the statistical significance of these observations. Overall, large de novo CNVs, particularly those encompassing multiple genes, confer substantial risks (OR = 5.6; CI = 2.6-12.0, p = 2.4 x 10(-7)). We estimate there are 130-234 ASD-related CNV regions in the human genome and present compelling evidence, based on cumulative data, for association of rare de novo events at 7q11.23, 15q11.2-13.1, 16p11.2, and Neurexin 1.

AB Despite the fact that epithelial ovarian cancers are the leading cause of death from gynecological cancer, very little is known about the pathophysiology of the disease. Mutations in the WNT and PI3K pathways are frequently observed in the human ovarian endometrioid adenocarcinomas (OEAs). However, the role of WNT/beta-catenin and PTEN/AKT signaling in the etiology and/or progression of this disease is currently unclear. In this report we show that mice with a gain-of-function mutation in beta-catenin that leads to dysregulated nuclear accumulation of beta-catenin expression in the ovarian surface epithelium (OSE) cells develop indolent, undifferentiated tumors with both mesenchymal and epithelial characteristics. Combining dysregulated beta-catenin with homozygous deletion of PTEN in the OSE resulted in development of significantly more aggressive tumors, which was correlated with inhibition of p53 expression and cellular senescence. Induced expression of both mTOR kinase, a master regulator of proliferation, and phosphorylation of its downstream target, S6Kinase was also observed in both the indolent and aggressive mouse tumors, as well as in human OEA with nuclear beta-catenin accumulation. Ectopic allotransplants of the mouse ovarian tumor cells with a gain-of-function mutation in beta-catenin and PTEN deletion developed into tumors with OEA histology, the growth of which were significantly inhibited by oral rapamycin treatment. These studies demonstrate that rapamycin might be an effective therapeutic for human ovarian endometrioid patients with dysregulated Wnt/beta-catenin and Pten/PI3K signaling.

AB The role of high-dose therapy followed by autologous stem cell transplantation (ASCT) in the treatment of multiple myeloma (MM) continues to evolve in the novel agent era. The choice of induction therapy has moved from conventional chemotherapy to newer regimens incorporating the immunomodulatory derivatives thalidomide or lenalidomide and the proteasome inhibitor bortezomib. These drugs combine well with traditional therapies and with one another to form various doublet, triplet, and quadruplet regimens. Up-front use of these induction treatments, in particular 3-drug combinations, has affected unprecedented rates of complete response that rival those previously seen with conventional chemotherapy and subsequent ASCT. Autotransplantation applied after novel-agent-based induction regimens provides further improvement in the depth of response, a gain that translates into extended progression-free survival and, potentially, overall survival. High activity shown by immunomodulatory derivatives and bortezomib before ASCT has recently led to their use as consolidation and maintenance therapies after autotransplantation. Novel agents and ASCT are complementary treatment strategies for MM. This article reviews the current literature and provides important perspectives and guidance on the major issues surrounding the optimal current management of younger, transplantation-eligible MM patients.

AB Integrin-beta 7 (ITGB7) mRNA is detected in multiple myeloma (MM) cells and its presence is correlated with MAF gene activation. Although the involvement of several integrin family members in MM-stoma cell interaction is well documented, the specific biologic functions regulated by integrin-beta 7 in MM are largely unknown. Clinically, we have correlated integrin-beta 7 expression in MM with poor survival outcomes post autologous stem cell transplantation and postsalvage therapy with bortezomib. Functionally, we have found that shRNA-mediated silencing of ITGB7 reduces MM-cell adhesion to extracellular matrix elements (fibronectin, E-cadherin) and reverses cell-adhesion-mediated drug resistance (CAM-DR) sensitizing them to bortezomib and melphalan. In addition, ITGB7 silencing abrogated MM-cell transwell migration in response to SDF1 alpha gradients, reduced vessel density in xenografted tumors, and altered MM cells in vivo homing into the BM. Mechanistically, ITGB7 knockdown inhibited focal adhesion kinase (FAK) and Src phosphorylation, Rac1 activation, and SUMOylation, reduced VEGF production in MM-BM stem cell cocultures and attenuated p65-NF-kappa B activity. Our findings support a role for integrin-beta 7 in MM-cell adhesion, migration, and BM homing, and pave the way for a novel therapeutic approach targeting this molecule.

AB Hepcidin, a hormone produced mainly by the liver, has been shown to inhibit both intestinal iron absorption and iron release from macrophages. Hemojuvelin, a glycophosphatidyl inositol-linked membrane protein, acts as a bone morphogenetic protein coreceptor to activate hepcidin expression through a SMAD signaling pathway in hepatocytes. In the present study, we show in mice that loss of hemojuvelin specifically in the liver leads to decreased liver hepcidin production and increased tissue and serum iron levels. Although it does not have any known function outside of the liver, hemojuvelin is expressed at very high levels in cardiac and skeletal muscle. To explore possible roles for hemojuvelin in skeletal muscle, we analyzed conditional knockout mice that lack muscle hemojuvelin. The mutant animals had no apparent phenotypic abnormalities. We found that systemic iron homeostasis and liver hepcidin expression were not affected by loss of hemojuvelin in skeletal muscle regardless of dietary iron content. We conclude that, in spite of its expression pattern, hemojuvelin is primarily important in the liver. (Blood. 2011; 117(23): 6319-6325)

AB Thrombin is a positive mediator of thrombus formation through the proteolytic activation of protease-activated receptors (PARs), fibrinogen, factor XI (fXI), and other substrates, and a negative regulator through activation of protein C, a natural anticoagulant with anti-inflammatory/ cytoprotective properties. Protease-engineering studies have established that 2 active-site substitutions, W215A and E217A (fII(WE)), result in dramatically reduced catalytic efficiency with procoagulant substrates while largely preserving thrombomodulin (TM)-dependent protein C activation. To explore the hypothesis that a prothrombin variant favoring anti-thrombotic pathways would be compatible with development but limit inflammatory processes in vivo, we generated mice carrying the fII(WE) mutations within the endogenous prothrombin gene. Unlike fII(WE) embryos, fII(WE/WE) mice uniformly developed to term. Nevertheless, these mice ultimately succumbed to spontaneous bleeding events shortly after birth. Heterozygous fII(WT/WE) mice were viable and fertile despite a shift toward an anti-thrombotic phenotype exemplified by prolonged tail-bleeding times and times-to-occlusion after FeCl(3) vessel injury. More interestingly, prothrombin(WE) expression significantly ameliorated the development of inflammatory joint disease in mice challenged with collagen-induced arthritis (CIA). The administration of active recombinant thrombin(WE) also suppressed the development of CIA in wildtype mice. These studies provide a proof-of-principle that pro/thrombin variants engineered with altered substrate specificity may offer therapeutic opportunities for limiting inflammatory disease processes.

TI In vivo imaging of T-reg cells providing immune privilege to the
haematopoietic stem-cell niche
SO NATURE
LA English
DT Article
ID BONE-MARROW NICHE; ENGRAFTMENT
AB Stem cells reside in a specialized regulatory microenvironment or niche(1,2), where they receive appropriate support for maintaining self-renewal and multi-lineage differentiation capacity(1-3). The niche may also protect stem cells from environmental insults(3) including cytotoxic chemotherapy and perhaps pathogenic immunity(4). The testis, hair follicle and placenta are all sites of residence for stem cells and are immune-suppressive environments, called immune-privileged sites, where multiple mechanisms cooperate to prevent immune attack, even enabling prolonged survival of foreign allografts without immunosuppression(4). We sought to determine if somatic stem-cell niches more broadly are immune-privileged sites by examining the haematopoietic stem/progenitor cell (HSPC) niche(1,2,5-7) in the bone marrow, a site where immune reactivity exists(8,9). We observed persistence of HSPCs from allogeneic donor mice (allo-HSPCs) in non-irradiated recipient mice for 30 days without immunosuppression with the same survival frequency compared to syngeneic HSPCs. These HSPCs were lost after the depletion of FoxP3 regulatory T (T-reg) cells. High-resolutionin vivo imaging over time demonstrated marked co-localization of HSPCs with T-reg cells that accumulated on the endosteal surface in the calvarial and trabecular bone marrow. T-reg cells seem to participate in creating a localized zone where HSPCs reside and where T-reg cells are necessary for allo-HSPC persistence. In addition to processes supporting stem-cell function, the niche will provide a relative sanctuary from immune attack.

AB Transplant tolerance, defined as indefinite allograft survival without immunosuppression, has been regularly achieved in laboratory mice but not in nonhuman primates or humans. In contrast to laboratory mice, primates regularly have high frequencies of alloreactive memory T cells (TMEMs) before transplantation. These TMEMs are poorly sensitive to conventional immunosuppression and costimulation blockade, and the presence of donor-reactive TMEMs in primates may account for their resistance to transplant tolerance protocols that have proven consistently effective in mice. We measured the frequencies of anti-donor TMEMs before and after transplantation in a series of rejecting and tolerant monkeys that underwent nonmyeloablative conditioning, short-term immunosuppression, and combined allogeneic kidney/cell transplantation. Transplants were acutely rejected in all the monkeys with high numbers of donor-specific TMEMs before transplantation. In contrast, long-term survival was observed in the recipients harboring lower frequencies of anti-donor TMEMs before transplantation. Similar amounts of TMEM homeostatic expansion were recorded in all transplanted monkeys upon hematopoietic reconstitution; however, only the tolerant monkeys had no expansion or activation of donor-reactive TMEMs after transplantation. These results indicate that the presence of high frequencies of host donor-reactive TMEMs before transplantation impairs tolerance induction to kidney allografts in this nonhuman primate model. Indeed, recipients harboring a low anamnestic reactivity to their donor before transplantation were successfully rendered tolerant via infusion of donor cells and short-term immunosuppression. This suggests that selection of allogeneic donors with low memory responses in recipients may be essential to successful transplant tolerance induction in patients.

AB To uncover shared pathogenic mechanisms among the highly heterogeneous autism spectrum disorders (ASDs), we developed a protein interaction network that identified hundreds of new interactions among proteins encoded by ASD-associated genes. We discovered unexpectedly high connectivity between SHANK and TSC1, previously implicated in syndromic autism, suggesting that common molecular pathways underlie autistic phenotypes in distinct syndromes. ASD patients were more likely to harbor copy number variations that encompass network genes than were control subjects. We also identified, in patients with idiopathic ASD, three de novo lesions (deletions in 16q23.3 and 15q22 and one duplication in Xq28) that involve three network genes (NECAB2, PKM2, and FLNA). The protein interaction network thus provides a framework for identifying causes of idiopathic autism and for understanding molecular pathways that underpin both syndromic and idiopathic ASDs.

AB Background: Chronic kidney disease and end-stage renal disease are major causes of morbidity and mortality that are seen far more commonly in the aged population. Interestingly, kidney function declines during aging even in the absence of underlying renal disease. Declining renal function has been associated with age-related cellular damage and dysfunction with reports of increased levels of apoptosis, necrosis, and inflammation in the aged kidney. Bioactive sphingolipids have been shown to regulate these same cellular processes, and have also been suggested to play a role in aging and cellular senescence.
Methodology/Principal Findings: We hypothesized that alterations in kidney sphingolipids play a role in the declining kidney function that occurs during aging. To begin to address this, the sphingolipid profile was measured in young (3 mo), middle aged (9 mo) and old (17 mo) C57BL/6 male mice. Interestingly, while modest changes in ceramides and sphingoid bases were evident in kidneys from older mice, the most dramatic elevations were seen in long-chain hexosylceramides (HexCer) and lactosylceramides (LacCer), with C14-and C16-lactosylceramides elevated as much as 8 and 12-fold, respectively. Increases in long-chain LacCers during aging are not exclusive to the kidney, as they also occur in the liver and brain. Importantly, caloric restriction, previously shown to prevent the declining kidney function seen in aging, inhibits accumulation of long-chain HexCer/LacCers and prevents the age-associated elevation of enzymes involved in their synthesis. Additionally, long-chain LacCers are also significantly elevated in human fibroblasts isolated from elderly individuals.
Conclusion/Significance: This study demonstrates accumulation of the glycosphingolipids HexCer and LacCer in several different organs in rodents and humans during aging. In addition, data demonstrate that HexCer and LacCer metabolism is regulated by caloric restriction. Taken together, data suggest that HexCer/LacCers are important mediators of cellular processes fundamental to mammalian aging.

AB Despite exhibiting oncogenic events, patient's leukemia cells are responsive and dependent on signals from their malignant bone marrow (BM) microenvironment, which modulate their survival, cell cycle progression, trafficking and resistance to chemotherapy. Identification of the signaling pathways mediating this leukemia/microenvironment interplay is critical for the development of novel molecular targeted therapies.
We observed that primary leukemia B-cell precursors aberrantly express receptors of the BAFF-system, BAFF-R, BCMA, and TACI. These receptors are functional as their ligation triggers activation of NF-kappa B, MAPK/JNK, and Akt signaling. Leukemia cells express surface BAFF and APRIL ligands, and soluble BAFF is significantly higher in leukemia patients in comparison to age-matched controls. Interestingly, leukemia cells also express surface APRIL, which seems to be encoded by APRIL-delta, a novel isoform that lacks the furin convertase domain. Importantly, we observed BM microenvironmental cells express the ligands BAFF and APRIL, including surface and secreted BAFF by BM endothelial cells. Functional studies showed that signals through BAFF-system receptors impact the survival and basal proliferation of leukemia B-cell precursors, and support the involvement of both homotypic and heterotypic mechanisms.
This study shows an unforeseen role for the BAFF-system in the biology of precursor B-cell leukemia, and suggests that the target disruption of BAFF signals may constitute a valid strategy for the treatment of this cancer.

DEVELOPMENT; XENOPUS RETINA; NULL MICE; DIFFERENTIATION
AB Multipotent progenitor cells in the otic placode give rise to the specialized cell types of the inner ear, including neurons, supporting cells, and hair cells. The mechanisms governing acquisition of specific fates by the cells that form the cochleovestibular organs remain poorly characterized. Here we show that whereas blocking Notch signaling with a gamma-secretase inhibitor increased the conversion of inner ear stem cells to hair cells by a mechanism that involved the upregulation of bHLH transcription factor, Math1 ( mouse Atoh1), differentiation to a neuronal lineage was increased by expression of the Notch intracellular domain. The shift to a neuronal lineage could be attributed in part to continued cell proliferation in cells that did not undergo sensory cell differentiation due to the high Notch signaling, but also involved upregulation of Ngn1. The Notch intracellular domain influenced Ngn1 indirectly by upregulation of Sox2, a transcription factor expressed in many neural progenitor cells, and directly by an interaction with an RBP-J binding site in the Ngn1 promoter/enhancer. The induction of Ngn1 was blocked partially by mutation of the RBP-J site and nearly completely when the mutation was combined with inhibition of Sox2 expression. Thus, Notch signaling had a significant role in the fate specification of neurons and hair cells from inner ear stem cells, and decisions about cell fate were mediated in part by a differential effect of combinatorial signaling by Notch and Sox2 on the expression of bHLH transcription factors.

AB Background: Squamous cell lung carcinomas account for approximately 25% of new lung carcinoma cases and 40,000 deaths per year in the United States. Although there are multiple genomically targeted therapies for lung adenocarcinoma, none has yet been reported in squamous cell lung carcinoma.
Methodology/Principal Findings: Using SNP array analysis, we found that a region of chromosome segment 8p11-12 containing three genes-WHSC1L1, LETM2, and FGFR1-is amplified in 3% of lung adenocarcinomas and 21% of squamous cell lung carcinomas. Furthermore, we demonstrated that a non-small cell lung carcinoma cell line harboring focal amplification of FGFR1 is dependent on FGFR1 activity for cell growth, as treatment of this cell line either with FGFR1-specific shRNAs or with FGFR small molecule enzymatic inhibitors leads to cell growth inhibition.
Conclusions/Significance: These studies show that FGFR1 amplification is common in squamous cell lung cancer, and that FGFR1 may represent a promising therapeutic target in non-small cell lung cancer.

AB Two-photon calcium imaging is now an important tool for in vivo imaging of biological systems. By enabling neuronal population imaging with subcellular resolution, this modality offers an approach for gaining a fundamental understanding of brain anatomy and physiology. Proper analysis of calcium imaging data requires denoising, that is separating the signal from complex physiological noise. To analyze two-photon brain imaging data, we present a signal plus colored noise model in which the signal is represented as harmonic regression and the correlated noise is represented as an order p autoregressive process. We provide an efficient cyclic descent algorithm to compute approximate maximum likelihood parameter estimates by combing a weighted least-squares procedure with the Burg algorithm. We use Akaike information criterion to guide selection of the harmonic regression and the autoregressive model orders. Our flexible yet parsimonious modeling approach reliably separates stimulus-evoked fluorescence response from background activity and noise, assesses goodness of fit, and estimates confidence intervals and signal-to-noise ratio. This refined separation leads to appreciably enhanced image contrast for individual cells including clear delineation of subcellular details and network activity. The application of our approach to in vivo imaging data recorded in the ferret primary visual cortex demonstrates that our method yields substantially denoised signal estimates. We also provide a general Volterra series framework for deriving this and other signal plus correlated noise models for imaging. This approach to analyzing two-photon calcium imaging data may be readily adapted to other computational biology problems which apply correlated noise models.

AB BACKGROUND: Human papillomavirus (HPV) type 16 is associated with oropharyngeal carcinomas (OPC). Antibodies (Abs) to HPV16 E6 and E7 oncoproteins have been detected in patient sera; however, Abs to other early HPV-derived proteins have not been well explored.
METHODS: Antibodies to the HPV16 proteome were quantified using a novel multiplexed bead assay, using C-terminal GST-fusion proteins captured onto Luminex beads. Sera were obtained from untreated patients with OPC (N=40), partners of patients with HPV16 + OPC (N = 11), and healthy controls (N = 50).
RESULTS: Oropharyngeal carcinomas patients with known virus-like capsid particle + Abs had elevated serum Abs to HPV16 E1, E2, E4, E6, and E7, and L1 antibody levels, but not E5. The ratios of specific median fluorescence intensity to p21-GST compared with controls were E1: 50.7 vs 2.1; E4: 14.6 vs 1.3; E6: 11.3 vs 2.4; E7: 43.1 vs 2.6; and L1: 10.3 vs 2.6 (each P <= 0.01). In a validation cohort, HPV16 E1, E2, and E7 antibody levels were significantly elevated compared with healthy control samples (P <= 0.02) and partners of OPC patients (P <= 0.01).
CONCLUSION: Patients with HPV16 + OPC have detectable Abs to E1, E2, and E7 proteins, which are potential biomarkers for HPV-associated OPC. British Journal of Cancer (2011) 104, 1896-1905. doi:10.1038/bjc.2011.171 www.bjcancer.com (C) 2011 Cancer Research UK

TI Guanine nucleotide exchange factor Vav1 regulates perivascular homing
and bone marrow retention of hematopoietic stem and progenitor cells

RECEPTORS; VLA-4; SDF-1
AB Engraftment and maintenance of hematopoietic stem and progenitor cells (HSPC) depend on their ability to respond to extracellular signals from the bone marrow microenvironment, but the critical intracellular pathways integrating these signals remain poorly understood. Furthermore, recent studies provide contradictory evidence of the roles of vascular versus osteoblastic niche components in HSPC function. To address these questions and to dissect the complex upstream regulation of Rac GTPase activity in HSPC, we investigated the role of the hematopoietic-specific guanine nucleotide exchange factor Vav1 in HSPC localization and engraftment. Using intravital microscopy assays, we demonstrated that transplanted Vav1(-/-) HSPC showed impaired early localization near nestin(+) perivascular mesenchymal stem cells; only 6.25% of Vav1(-/-) HSPC versus 45.8% of wild-type HSPC were located less than 30 mu m from a nestin(+) cell. Abnormal perivascular localization correlated with decreased retention of Vav1(-/-) HSPC in the bone marrow (44-60% reduction at 48 h posttransplant, compared with wild-type) and a very significant defect in short- and long-term engraftment in competitive and noncompetitive repopulation assays (<1.5% chimerism of Vav1(-/-) cells vs. 53-63% for wild-type cells). The engraftment defect of Vav1(-/-) HSPC was not related to alterations in proliferation, survival, or integrin-mediated adhesion. However, Vav1(-/-) HSPC showed impaired responses to SDF1 alpha, including reduced in vitro migration in time-lapse microscopy assays, decreased circadian and pharmacologically induced mobilization in vivo, and dysregulated Rac/Cdc42 activation. These data suggest that Vav1 activity is required specifically for SDF1 alpha-dependent perivascular homing of HSPC and suggest a critical role for this localization in retention and subsequent engraftment.

AB Background: The Veterans Health Administration (VHA) is the largest integrated health care system in the United States. Studies suggest that the VHA provides better preventive care and care for some chronic illnesses than does the private sector.
Objective: To assess the quality of cancer care for older patients provided by the VHA versus fee-for-service Medicare.
Design: Observational study of patients with cancer that was diagnosed between 2001 and 2004 who were followed through 2005.
Setting: VHA and non-VHA hospitals and office-based practices.
Patients: Men older than 65 years with incident colorectal, lung, or prostate cancer; lymphoma; or multiple myeloma.
Measurements: Rates of processes of care for colorectal, lung, or prostate cancer; lymphoma; or multiple myeloma. Rates were adjusted by using propensity score weighting.
Results: Compared with the fee-for-service Medicare population, the VHA population received diagnoses of colon (P < 0.001) and rectal (P = 0.007) cancer at earlier stages and had higher adjusted rates of curative surgery for colon cancer (92.7% vs. 90.5%; P < 0.010), standard chemotherapy for diffuse large B-cell non-Hodgkin lymphoma (71.1% vs. 59.3%; P < 0.001), and bisphosphonate therapy for multiple myeloma (62.1% vs. 50.4%; P < 0.001). The VHA population had lower adjusted rates of 3-dimensional conformal or intensity-modulated radiation therapy for prostate cancer treated with external-beam radiation therapy (61.6% vs. 86.0%; P < 0.001). Adjusted rates were similar for 9 other measures. Sensitivity analyses suggest that if patients with cancer in the VHA system have more severe comorbid illness than other patients, rates for most indicators would be higher in the VHA population than in the fee-for-service Medicare population.
Limitation: This study included only older men and did not include information about performance status, severity of comorbid illness, or patient preferences.
Conclusion: Care for older men with cancer in the VHA system was generally similar to or better than care for fee-for-service Medicare beneficiaries, although adoption of some expensive new technologies may be delayed in the VHA system.

AB Background: Lung cancer is the leading cause of cancer death in the United States. Identifying factors associated with stage of diagnosis can improve our understanding of biologic and behavioral pathways of lung cancer development and detection. We used data from a prospective cohort study to evaluate associations of demographic, health history, and health behaviors with early versus late stage at diagnosis of non-small cell lung cancer (NSCLC).
Methods: We calculated odds ratios (ORs) for the association of patient-level characteristics with advanced stage of diagnosis for NSCLC. The OR's were then adjusted for age, gender, race/ethnicity, smoking status, income, education, chronic obstructive pulmonary disease, and a comorbidity index.
Results: We identified 612 cases of NSCLC among 77,719 adults, aged 50 to 76 years from Washington State recruited in 2000-2002, with followup through December 2007. In univariate analyses, subjects who quit smoking <10 years (OR 2.56, 95% CI 1.17 - 5.60) and were college graduates (OR 1.67, 95% CI, 1.00 - 2.76) had increased risks of being diagnosed with advanced stage NSCLC, compared to never smokers and non-college graduates, respectively. Receipt of sigmoidoscopy/colonoscopy, compared to no receipt, was associated with a decreased risk of advanced stage (OR 0.65, 95% CI, 0.43 - 0.99). The adjusted OR for receipt of sigmoidoscopy/colonoscopy was 0.55 (95% CI, 0.36 - 0.86). There was evidence that increasing the number of screening activities was associated with a decreased risk of advanced stage NSCLC (P for trend = 0.049).
Conclusions: Smoking status, education, and a screening activity were associated with stage at diagnosis of NSCLC. These results may guide future studies of the underlying mechanisms that influence how NSCLC is detected and diagnosed.

AB Innate-like NKT cells conspicuously accumulate within the liver microvasculature of healthy mice, crawling on the luminal side of endothelial cells, but their general recirculation pattern and the mechanism of their intravascular behavior have not been elucidated. Using parabiotic mice, we demonstrated that, despite their intravascular location, most liver NKT cells failed to recirculate. Antibody blocking experiments established that they were retained locally through constitutive LFA-1-intercellular adhesion molecule (ICAM) 1 interactions. This unprecedented lifelong intravascular residence could be induced in conventional CD4 T cells by the sole expression of promyelocytic leukemia zinc finger (PLZF), a transcription factor specifically expressed in the NKT lineage. These findings reveal the unique genetic and biochemical pathway that underlies the innate intravascular surveillance program of NKT cells.

AB Transgenic models of Alzheimer's disease (AD) have made significant contributions to our understanding of AD pathogenesis, and are useful tools in the development of potential therapeutics. The fruit fly, Drosophila melanogaster, provides a genetically tractable, powerful system to study the biochemical, genetic, environmental, and behavioral aspects of complex human diseases, including AD. In an effort to model AD, we over-expressed human APP and BACE genes in the Drosophila central nervous system. Biochemical, neuroanatomical, and behavioral analyses indicate that these flies exhibit aspects of clinical AD neuropathology and symptomology. These include the generation of A beta(40) and A beta(42), the presence of amyloid aggregates, dramatic neuroanatomical changes, defects in motor reflex behavior, and defects in memory. In addition, these flies exhibit external morphological abnormalities. Treatment with a gamma-secretase inhibitor suppressed these phenotypes. Further, all of these phenotypes are present within the first few days of adult fly life. Taken together these data demonstrate that this transgenic AD model can serve as a powerful tool for the identification of AD therapeutic interventions.

AB Background: Many studies have investigated racial/ethnic disparities in medication non-adherence in patients with type 2 diabetes using common measures such as medication possession ratio (MPR) or gaps between refills. All these measures including MPR are quasi-continuous and bounded and their distribution is usually skewed. Analysis of such measures using traditional regression methods that model mean changes in the dependent variable may fail to provide a full picture about differential patterns in non-adherence between groups.
Methods: A retrospective cohort of 11,272 veterans with type 2 diabetes was assembled from Veterans Administration datasets from April 1996 to May 2006. The main outcome measure was MPR with quantile cutoffs Q1-Q4 taking values of 0.4, 0.6, 0.8 and 0.9. Quantile-regression (QReg) was used to model the association between MPR and race/ethnicity after adjusting for covariates. Comparison was made with commonly used ordinary-least-squares (OLS) and generalized linear mixed models (GLMM).
Results: Quantile-regression showed that Non-Hispanic-Black (NHB) had statistically significantly lower MPR compared to Non-Hispanic-White (NHW) holding all other variables constant across all quantiles with estimates and p-values given as -3.4% (p = 0.11), -5.4% (p = 0.01), -3.1% (p = 0.001), and -2.00% (p = 0.001) for Q1 to Q4, respectively. Other racial/ethnic groups had lower adherence than NHW only in the lowest quantile (Q1) of about -6.3% (p = 0.003). In contrast, OLS and GLMM only showed differences in mean MPR between NHB and NHW while the mean MPR difference between other racial groups and NHW was not significant.
Conclusion: Quantile regression is recommended for analysis of data that are heterogeneous such that the tails and the central location of the conditional distributions vary differently with the covariates. QReg provides a comprehensive view of the relationships between independent and dependent variables (i.e. not just centrally but also in the tails of the conditional distribution of the dependent variable). Indeed, without performing QReg at different quantiles, an investigator would have no way of assessing whether a difference in these relationships might exist.

AB The ubiquitously expressed Calpains 1 and 2 belong to a family of calcium-dependent intracellular cysteine proteases. Both calpains are heterodimers consisting of a large subunit and a small regulatory subunit encoded by the gene Capns1. To investigate a role for the calpain small subunit in cells of the osteoblast lineage in vivo, we previously generated osteoblast-specific Capns1 knockout mice and characterized their bone phenotype. In this study, we further examined effects of low calcium and high fat diets on their bone, fat, and glucose homeostasis.
Osteoblast-specific Capns1 knockout mice showed significantly reduced serum levels of total and uncarboxylated osteocalcin, and this was presumably due to their impaired bone formation and bone resorption. The reduced bone resorptive function of the mutant mice was also significant under a low calcium diet. Thus, these results suggest that reduced uncarboxylated osteocalcin levels of mutant mice were, at least in part, due to their osteoporotic bone with impaired bone resorptive function. Interestingly, unlike osteocalcin knockout mice, mutant mice on a normal chow diet were leaner than control littermates: this was likely due to their reduced food intake and overall lower energy homeostasis. To test this hypothesis, we next provided mutant mice with a high fat diet and further examined an effect of their reduced uncarboxylated osteocalcin levels on body composition and glucose metabolism. The average mean body weight of mutant mice became indistinguishable with that of controls after 2 weeks on a high fat diet, and continued to show an upward trend, at least, up to 6 weeks. Moreover, mutant mice on a high fat diet exhibited a significant increase in serum levels of leptin and resistin, adipocyte-specific adipokines, and developed impaired glucose tolerance. Collectively, mice with osteoporosis and reduced bone resorptive function showed reduced serum uncarboxylated osteocalcin levels and were susceptible to increase body adiposity and develop impaired glucose tolerance under a high fat diet.

TI Fine epitope mapping of monoclonal antibodies against hemagglutinin of a
highly pathogenic H5N1 influenza virus using yeast surface display

AB Highly pathogenic H5N1 avian influenza viruses pose a debilitating pandemic threat. Thus, understanding mechanisms of antibody-mediated viral inhibition and neutralization escape is critical. Here, a robust yeast display system for fine epitope mapping of viral surface hemagglutinin (HA)-specific antibodies is demonstrated. The full-length H5 subtype HA (HA0) was expressed on the yeast surface in a correctly folded conformation, determined by binding of a panel of extensively characterized neutralizing human monoclonal antibodies (mAbs). These mAbs target conformationally-dependent epitopes of influenza A HA, which are highly conserved across H5 clades and group 1 serotypes. By separately displaying HA1 and HA2 subunits on yeast, domain mapping of two anti-H5 mAbs, NR2728 and H5-2A, localized their epitopes to HA1. These anti-H5 mAb epitopes were further fine mapped by using a library of yeast-displayed HA1 mutants and selecting for loss of binding without prior knowledge of potential contact residues. By overlaying key mutant residues that impacted binding onto a crystal structure of HA, the NR2728 mAb was found to interact with a fully surface-exposed contiguous patch of residues at the receptor binding site (RBS), giving insight into the mechanism underlying its potent inhibition of virus binding. The non-neutralizing H5-2A mAb was similarly mapped to a highly conserved H5 strain-specific but poorly accessible location on a loop at the trimer HA interface. These data further augment our tool-chest for studying HA antigenicity, epitope diversity and accessibility in response to natural and experimental influenza infection and vaccines.

AB Non-articulated energy storage and return prosthetic feet lack any true articulation or obvious point of rotation. This makes it difficult to select a joint center about which to estimate their kinetics. Despite this absence of any clear point of rotation, methods for estimating the kinetic performance of this class of prosthetic feet typically assume that they possess a fixed center of rotation and that its location is well approximated by the position of the contralateral lateral malleolus. To evaluate the validity of this assumption we used a finite helical axis approach to determine the position of the center of rotation in the sagittal plane for a series of non-articulated energy storage and return prosthetic feet. We found that over the course of stance phase, the sagittal finite helical axis position diverged markedly from the typically assumed fixed axis location. These results suggest that researchers may need to review center of rotation assumptions when assessing prosthetic foot kinetics, while clinicians may need to reconsider the criteria by which they prescribe these prosthetic feet.

AB The angiotensin II peptide analog [Sar(1), Ile(4), Ile(8)] AngII (SII) is a biased AT(1A) receptor agonist that stimulates receptor phosphorylation, beta-arrestin recruitment, receptor internalization, and beta-arrestin-dependent ERK1/2 activation without activating heterotrimeric G-proteins. To determine the scope of G-protein- independent AT(1A) receptor signaling, we performed a gelbased phosphoproteomic analysis of AngII and SII-induced signaling in HEK cells stably expressing AT(1A) receptors. A total of 34 differentially phosphorylated proteins were detected, of which 16 were unique to SII and eight to AngII stimulation. MALDI-TOF/TOF mass fingerprinting was employed to identify 24 SII-sensitive phosphoprotein spots, of which three (two peptide inhibitors of protein phosphatase 2A (I1PP2A and I2PP2A) and prostaglandin E synthase 3 (PGES3)) were selected for validation and further study. We found that phosphorylation of I2PP2A was associated with rapid and transient inhibition of a beta-arrestin 2-associated pool of protein phosphatase 2A, leading to activation of Akt and increased phosphorylation of glycogen synthase kinase 3 beta in an arrestin signalsome complex. SII-stimulated PGES3 phosphorylation coincided with an increase in beta-arrestin 1-associated PGES3 and an arrestin-dependent increase in cyclooxygenase 1-dependent prostaglandin E-2 synthesis. These findings suggest that AT(1A) receptors regulate a robust G protein-independent signaling network that affects protein phosphorylation and autocrine/paracrine prostaglandin production and that these pathways can be selectively modulated by biased ligands that antagonize G protein activation.

AB The mechanisms by which sphingosine kinase-1 (SK-1)/sphingosine 1-phosphate (S1P) activation contributes to imatinib resistance in chronic myeloid leukemia (CML) are unknown. We show herein that increased SK-1/S1P enhances Bcr-Abl1 protein stability, through inhibition of its proteasomal degradation in imatinibresistant K562/IMA-3 and LAMA-4/IMA human CML cells. In fact, Bcr-Abl1 stability was enhanced by ectopic SK-1 expression. Conversely, siRNA-mediated SK-1 knockdown in K562/IMA-3 cells, or its genetic loss in SK-1(-/-) MEFs, significantly reduced Bcr-Abl1 stability. Regulation of Bcr-Abl1 by SK-1/S1P was dependent on S1P receptor 2 (S1P2) signaling, which prevented Bcr-Abl1 dephosphorylation, and degradation via inhibition of PP2A. Molecular or pharmacologic interference with SK-1/S1P2 restored PP2A-dependent Bcr-Abl1 dephosphorylation, and enhanced imatinib-or nilotinib-induced growth inhibition in primary CD34(+) mononuclear cells obtained from chronic phase and blast crisis CML patients, K562/IMA-3 or LAMA4/IMA cells, and 32Dcl3 murine progenitor cells, ex-pressing the wild-type or mutant (Y253H or T315I) Bcr-Abl1 in situ. Accordingly, impaired SK-1/S1P2 signaling enhanced the growth-inhibitory effects of nilotinib against 32D/T315I-Bcr-Abl1-derived mouse allografts. Since SK-1/S1P/S1P2 signaling regulates Bcr-Abl1 stability via modulation of PP2A, inhibition of SK-1/S1P2 axis represents a novel approach to target wild-type-ormutant-Bcr-Abl1 thereby overcoming drug resistance.

AB In a recent genome-wide association study, variants in 8 genes were associated with VWF level, a risk factor for venous thrombosis (VT). In an independent, population-based, case-control study of incident VT, we tested hypotheses that variants in these genes would be associated with risk. Cases were 656 women who experienced an incident VT, and controls comprised 710 women without a history of VT. DNA was obtained from whole blood. Logistic regression was used to test associations between incident VT and single nucleotide polymorphisms (SNPs) in 7 genes not previously shown to be associated with VT. Associations with P<.05 were candidates for replication in an independent case-control study of VT in both sexes. Two of the 7 SNPs tested yielded P<.05: rs1039084 (P=.005) in STXBP5, a novel candidate gene for VT, and rs1063856 (P=.04) in VWF, a gene whose protein level is associated with VT risk. Association results for the remaining 5 variants in SCARA5, STAB2, STX2, TC2N, and CLEC4M were not significant. Both STXBP5 and VWF findings were replicated successfully. Variation in genes associated with VWF levels in the genome-wide association study was found to be independently associated with incident VT. (Blood. 2011; 117(22): 6007-6011)

AB Background: The Zimbabwean national prevention of mother-to-child HIV transmission (PMTCT) program provided primarily single-dose nevirapine (sdNVP) from 2002-2009 and is currently replacing sdNVP with more effective antiretroviral (ARV) regimens.
Methods: Published HIV and PMTCT models, with local trial and programmatic data, were used to simulate a cohort of HIV-infected, pregnant/breastfeeding women in Zimbabwe (mean age 24.0 years, mean CD4 451 cells/mu L). We compared five PMTCT regimens at a fixed level of PMTCT medication uptake: 1) no antenatal ARVs (comparator); 2) sdNVP; 3) WHO 2010 guidelines using "Option A" (zidovudine during pregnancy/infant NVP during breastfeeding for women without advanced HIV disease; lifelong 3-drug antiretroviral therapy (ART) for women with advanced disease); 4) WHO "Option B" (ART during pregnancy/breastfeeding without advanced disease; lifelong ART with advanced disease); and 5) "Option B+:" lifelong ART for all pregnant/breastfeeding, HIV-infected women. Pediatric (4-6 week and 18-month infection risk, 2-year survival) and maternal (2-and 5-year survival, life expectancy from delivery) outcomes were projected.
Results: Eighteen-month pediatric infection risks ranged from 25.8% (no antenatal ARVs) to 10.9% (Options B/B+). Although maternal short-term outcomes (2-and 5-year survival) varied only slightly by regimen, maternal life expectancy was reduced after receipt of sdNVP (13.8 years) or Option B (13.9 years) compared to no antenatal ARVs (14.0 years), Option A (14.0 years), or Option B+ (14.5 years).
Conclusions: Replacement of sdNVP with currently recommended regimens for PMTCT (WHO Options A, B, or B+) is necessary to reduce infant HIV infection risk in Zimbabwe. The planned transition to Option A may also improve both pediatric and maternal outcomes.

AB Oncolytic viruses (OVs) represent a relatively novel anti-cancer modality. Like other new cancer treatments, effective OV therapy will likely require combination with conventional treatments. In order to design combinatorial treatments that work well together, a greater scrutiny of the mechanisms behind the individual treatments is needed. Sindbis virus (SV) based vectors have previously been shown to target and kill tumors in xenograft, syngeneic, and spontaneous mouse models. However, the effect of SV treatment on the immune system has not yet been studied. Here we used a variety of methods, including FACS analysis, cytotoxicity assays, cell depletion, imaging of tumor growth, cytokine blockade, and survival experiments, to study how SV therapy affects Natural Killer (NK) cell function in SCID mice bearing human ovarian carcinoma tumors. Surprisingly, we found that SV anti-cancer efficacy is largely NK cell-dependent. Furthermore, the enhanced therapeutic effect previously observed from Sin/IL12 vectors, which carry the gene for interleukin 12, is also NK cell dependent, but works through a separate IFN gamma-dependent mechanism, which also induces the activation of peritoneal macrophages. These results demonstrate the multimodular nature of SV therapy, and open up new possibilities for potential synergistic or additive combinatorial therapies with other treatments.

AB SCID mice provide an excellent platform for cancer research. Because of their lack of immunity, SOD mice readily succumb to infectious pathogens and therefore must be maintained in an SPF, barrier-protected environment. Although SPF and barrier facilities prevent infection, SOD mice remain prone to premature death due in part to a high prevalence of spontaneous thymic lymphomas. However, little is known about spontaneous nonthymic tumors in SCID mice. We therefore analyzed the incidence of nonthymic tumor in our defined-flora C.B-17/Icr-SCID/Sed mice and examined their histopathologic characteristics. We necropsied 1060 retired SCID breeders (506 males, 554 females; average ages of 325 and 320 d, respectively) and found that 24 mice had developed nonthymic tumors, yielding an incidence of 2.26% (1.78% in males; 2.71% in females). The incidence of nonthymic tumors was substantially lower than that of thymic lymphomas in our retired SCID breeders (12.3% in males; 4.15% in females). Based on histopathology, 9 nonthymic tumors in male SCID mice consisted of 4 salivary gland myoepitheliomas, 2 rhabdomyosarcomas, and 3 cases of leukemia involving multiple organs. Female SCID mice had 15 nonthymic tumors consisting of 8 mammary adenocarcinomas, 4 salivary gland myoepitheliomas, and 1 case each of leukemia, rhabdomyosarcoma, and fibrosarcoma. In addition, we tested in vivo transplantability and characterized the growth behavior of several of these tumors. To our knowledge, this report is the first comprehensive description of spontaneous nonthymic tumors, including 8 myoepitheliomas and 3 rhabdomyosarcomas, from the same SCID mouse colony.

AB Objective: To evaluate whether an association between risk of any of the factors of hypertension, alcohol intake, and cigarette smoking and the risk of primary open-angle glaucoma (POAG) depended on nitric oxide synthase 3 (NOS3) gene variants.
Methods: Two functional single-nucleotide polymorphisms (SNPs) (T-786C [rs2070744] and Glu298Asp [rs1799983]) and 2 tagging SNPs (rs7830 and rs3918188) were evaluated in nested case-control studies from the Nurses' Health Study (1980-2002) and the Health Professionals' Follow-up Study (1986-2002). Participants were 40 years of age or older and white, and were followed up biennially. We included 527 incident case patients with POAG and 1539 control participants, matched by cohort, age, and eye examination at the matched case patients' diagnosis dates. Cohort-specific relative risks were estimated using multivariable conditional logistic regression and were pooled using meta-analytic methods.
Results: The association between hypertension and POAG depended on T-786C SNP variants. Compared with TT homozygotes without hypertension, the TT homozygotes with hypertension were at significantly higher risk of POAG (relative risk, 1.45 [95% confidence interval, 1.01-2.08]); however, among carriers of the variant (C) allele, hypertension was not associated with POAG (P interaction = .007). Similarly, compared with CC homozygotes with the rs7830 tagging SNP who never smoked, CC homozygotes who were past or current smokers were at significantly higher risk of POAG(relative risk, 1.63 [95% confidence interval, 1.15-2.31]); however, among carriers of the variant allele (A), smoking was not associated with POAG (P interaction = .004). Interactions were not observed with alcohol intake.
Conclusions: The associations between hypertension and cigarette smoking in relation to POAG depended on NOS3 SNPs.

AB Comprehensive microscopy of distal esophagus could greatly improve the screening and surveillance of esophageal diseases such as Barrett's esophagus by providing histomorphologic information over the entire region at risk. Spectrally encoded confocal microscopy (SECM) is a high-speed reflectance confocal microscopy technology that can be configured to image the entire distal esophagus by helically scanning the beam using optics within a balloon-centering probe. It is challenging to image the human esophagus in vivo with balloon-based SECM, however, because patient motion and anatomic tissue surface irregularities decenter the optics, making it difficult to keep the focus at a predetermined location within the tissue as the beam is scanned. In this paper, we present a SECM probe equipped with an adaptive focusing mechanism that can compensate for tissue surface irregularity and dynamic focal variation. A tilted arrangement of the objective lens is employed in the SECM probe to provide feedback signals to an adaptive focusing mechanism. The tilted configuration also allows the probe to obtain reflectance confocal data from multiple depth levels, enabling the acquisition of three-dimensional volumetric data during a single scan of the probe. A tissue phantom with a surface area of 12.6 cm(2) was imaged using the new SECM probe, and 8 large-area reflectance confocal microscopy images were acquired over the depth range of 56 mu m in 20 minutes. Large-area SECM images of excised swine small intestine tissue were also acquired, enabling the visualization of villous architecture, epithelium, and lamina propria. The adaptive focusing mechanism was demonstrated to enable acquisition of in-focus images even when the probe was not centered and the tissue surface was irregular. (C)2011 Optical Society of America

AB Epidural injection is commonly used to provide intraoperative anesthesia, postoperative and obstetric analgesia, and to treat acute radicular pain. Identification of the epidural space is typically carried out using the loss of resistance (LOR) technique, but the usefulness of this technique is limited by false LOR and the inability to reliably detect intravascular or subarachnoid needle placement. In this study, we present a novel epidural needle that allows for the acquisition of optical reflectance spectra from tissue close to the beveled surface. This needle has optical fibers embedded in the cannula that deliver and receive light. With two spectrometers, light received from tissue is resolved across the wavelength range of 500 to 1600 nm. To determine the feasibility of optical tissue differentiation, spectra were acquired from porcine tissues during a post mortem laminectomy. The spectra were processed with an algorithm that derives estimates of the hemoglobin and lipid concentrations. The results of this study suggest that the optical epidural needle has the potential to improve the accuracy of epidural space identification. (C)2010 Optical Society of America

AB Laser Speckle Imaging (LSI) images interference patterns produced by coherent addition of scattered laser light to map subsurface tissue perfusion. However, the effect of longer path length photons is typically unknown and poses a limitation towards absolute quantification. In this work, LSI is integrated with spatial frequency domain imaging (SFDI) to suppress multiple scattering and absorption effects. First, depth sensitive speckle contrast is shown in phantoms by separating a deep source (4 mm) from a shallow source (2 mm) of speckle contrast by using a high spatial frequency of illumination (0.24 mm(-1)). We develop an SFD adapted correlation diffusion model and show that with high frequency (0.24 mm(-1)) illumination, doubling of absorption contrast results in only a 1% change in speckle contrast versus 25% change using a planar unmodulated (0 mm(-1)) illumination. Similar absorption change is mimicked in vivo imaging a finger occlusion and the relative speckle contrast change from baseline is 10% at 0.26 mm(-1) versus 60% at 0 mm(-1) during a finger occlusion. These results underscore the importance of path length and optical properties in determining speckle contrast. They provide an integrated approach for simultaneous mapping of blood flow (speckle contrast) and oxygenation (optical properties) which can be used to inform tissue metabolism.
