SO CLINICAL EPIGENETICS LA English DT Review DE Friedreich ataxia; heterochromatin; histone modifications; transcription; splicing; triplex AB Friedreich ataxia (FRDA) is a debilitating and frequently fatal neurological disorder that is recessively inherited. It belongs to the group of genetic disorders known as the Repeat Expansion Diseases, in which pathology arises from the deleterious consequences of the inheritance of a tandem repeat array whose repeat number exceeds a critical threshold. In the case of FRDA, the repeat unit is the triplet GAA.TTC and the tandem array is located in the first intron of the frataxin (FXN) gene. Pathology arises because expanded alleles make lower than normal levels of mature FXN mRNA and thus reduced levels of frataxin, the FXN gene product. The repeats form a variety of unusual DNA structures that have the potential to affect gene expression in a number of ways. For example, triplex formation in vitro and in bacteria leads to the formation of persistent RNA: DNA hybrids that block transcription. In addition, these repeats have been shown to affect splicing in model systems. More recently, it has been shown that the region flanking the repeats in the FXN gene is enriched for epigenetic marks characteristic of transcriptionally repressed regions of the genome. However, exactly how repeats in an intron cause the FXN mRNA deficit in FRDA has been the subject of much debate. Identifying the mechanism or mechanisms responsible for the FXN mRNA deficit in FRDA is important for the development of treatments for this currently incurable disorder. This review discusses evidence for and against different models for the repeat-mediated mRNA deficit.

Towards this goal, we adapt a higher-order probabilistic graphical model that makes the duality between supervoxels and their joint faces explicit and ensures that merging decisions are consistent and surfaces of final segments are closed. First, we propose a practical cutting-plane approach to solve the MAP inference problem to global optimality despite its NP-hardness. Second, we apply this approach to challenging large-scale 3D segmentation problems for neural circuit reconstruction (Connectomics), demonstrating the advantage of this higher-order model over independent decisions and finite-order approximations.

With the exception of human macrophages/monocytes, the consensus model of PV trafficking in host cells invokes endolysosomal maturation culminating in lysosome fusion. C. burnetii resists the degradative functions of the vacuole while at the same time exploiting the acidic pH for metabolic activation. While at first glance the mature PV resembles a large phagolysosome, an increasing body of evidence indicates the vacuole is in fact a specialized compartment that is actively modified by the pathogen. Adding to the complexity of PV biogenesis is new data showing vacuole engagement with autophagic and early secretory pathways. In this chapter, we review current knowledge of PV nature and development, and discuss disparate data related to the ultimate maturation state of PV harboring virulent or avirulent C. burnetii lipopolysaccharide phase variants in human mononuclear phagocytes.

Intracellular vacuolar pathogens such as Coxiella burnetii require lipids for both normal bacterial functions as well as formation of the acidic, phagolysosomal-like parasitophorous vacuole (PV) surrounding the bacteria. As an intracellular pathogen, C. burnetii can acquire lipid through both de novo bacterial synthesis and subversion of host cell pools. The C. burnetii genome encodes enzymes required for de novo synthesis of fatty acids and phospholipids. The high percentage of branched fatty acids suggests C. burnetii modifies these molecules to generate a bacterial cell envelope that can resist the harsh environment of the PV, such as the acidic pH. In addition to fatty acids and their derivatives, C. burnetii requires isoprenoids, particularly sterols as the PV membrane is cholesterol-rich. With the exception of two eukaryote-like sterol reductases, C. burnetii does not have the capability to generate cholesterol, suggesting sterols are actively diverted from the host cell. While C. burnetii utilizes host cell lipids for membrane biogenesis and possibly energy, bacterial manipulation of host cell lipid signaling pathways may support establishment of the intracellular niche. For example, effectors secreted by the C. burnetii Type IV secretion system may either directly or indirectly modify host cell lipids. Further understanding of the lipid biosynthetic capabilities of C. burnetii, along with C. burnetii's manipulation of host cell lipids, will provide insight into the host-pathogen relationship.

However, our understanding of the organism's physiology was greatly improved upon the discovery that C. burnetii requires an acidic pH for metabolic activation. Indeed, information gained from acid activation studies coupled with contemporary analyses using transcription microarrays, metabolic pathway reconstruction and metabolite typing, led to an axenic culture system that supports robust growth of C. burnetii. While axenic culture of C. burnetii can present some technical challenges, the technique is currently facilitating new lines of investigation and development of genetic tools. Axenic cultivation of C. burnetii should also prove useful in clinical settings. C1 NIAID, Coxiella Pathogenesis Sect, Intracellular Parasites Lab, Rocky Mt Labs,NIH, Hamilton, MT 59840 USA.

Other medically relevant obligate intracellular bacteria reside in the genera lifestyle presents a significant obstacle to genetic transformation. Procedures that are straightforward with free-living bacteria, such as antibiotic selection and cloning, can be very difficult when growth of transformants is restricted to a host cell. Longterm passage in host cells to expand small transformant populations can further complicate the procedure. Despite these and other obstacles, at least rudimentary systems are currently available for genetic transformation of most obligate intracellular bacterial pathogens. Dramatically aiding the development of new genetic methods for C. burnetii is the recent discovery of a medium that supports host cell-free growth of the organism in liquid, and importantly, on solid media as clonal colonies. The expanded C. burnetii genetics toolbox now includes transposon systems for random mutagenesis and single-copy, site-specific chromosomal gene knock-ins, as well as a shuttle vector for heterologous gene expression and in trans complementation. A reliable method of targeted gene inactivation remains a challenge. Advances in C. burnetii genetic manipulation will allow identification of genes essential for intracellular parasitism and disease pathogenesis, and undoubtedly fuel new interest in this minimally studied bacterial pathogen.

This review analyzes the strengths and weaknesses of the current developmental safety testing approaches in an effort to identify those strengths that should be retained in the future versus the weaknesses that should be eliminated. Workshop participants considered the following to be key strengths of current testing approaches: the integrated biology of pregnant animal models including pharmacokinetic and pharmacodynamic processes, the ability to detect low incidence malformations as well as maternally mediated toxicity, and the long history of use coupled with extensive historical data. A number of weaknesses were related to the resource-intensive nature of developmental toxicity testing (e.g., large number of animals, high costs, low throughput, and the inability to keep pace with the demand for more toxicity data). Other weaknesses included the use of very high dose levels that often far exceed human exposure levels, the confounding influence of maternal toxicity, sparse understanding of basic developmental mechanisms and genetics of standard animal models compared with mouse or lower organisms, difficulties interpreting low incidence findings, and issues surrounding the interpretation of minor skeletal variations. An appreciation of these strengths and weaknesses is critical for the design of new approaches to developmental toxicity testing in the 21st century.

CORM-2 reduced hypoxia-inducible factor-1 alpha (HIF-1 alpha) and endothelin-1 (ET-1) expression in normoxic and hypoxic cells, but while Hb alone significantly reduced HIF-1a stabilization in hypoxic cells, CO delivered by Hb (Hb-CO) had no effect on HIF-1 alpha stabilization. CO dose-dependently increased basal oxygen consumption and reduced overall mitochondrial respiratory capacity. Hb-CO increased basal oxygen consumption but did not alter respiratory capacity. Together, CO reduced ET-1, and, at low doses, had no effect on endothelial mitochondria oxygen consumption.

Specifically, hepatocellular carcinoma (HCC), the frequent malignant cancer with the third leading cause of cancer death, is a representative malignancy showing a strong association with chronic inflammatory disease. HCC develops almost exclusively in cirrhotic livers resulting from viral hepatitis, alcoholic or fatty liver disease. Several clinical studies indicate that >85% of HCCs retain markers for HBV and/or HCV. Cytokines, the most common mediators linking inflammation and cancer, show altered expression in cirrhotic disease and HCC, which can be categorized as pro-or anti-carcinogenesis. Thus, understanding the signaling pathway and the exploration of cytokine-based clinical management is representing a promising therapeutic strategy. In this chapter, we provide a general overview of the connection of inflammation and HCC and highlight the process of translating basic science to clinical managements by introducing two cytokines - tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6). Though promising, current cytokine-based therapies are at an early stage, for example, TNF-alpha have both pro- and anti-tumor effects, which lead to contradictory strategies in clinic applications. As our understanding of the mechanistic connections between inflammation and cancer development accumulate, the cytokine-based clinical management should be more specific and efficient in HCC prognosis, diagnosis and treatment.

This disease is transmitted by bites of infected sand flies, which inject saliva in the host skin in an attempt to obtain a blood meal. Sand fly saliva has an array of proteins with diverse pharmacological properties that modulates the host homeostatic and immune responses. Some of these proteins are also immunogenic and can induce both cellular and humoral immune responses. Recently, the use of sand fly salivary proteins to estimate exposure to sand fly bites and consequently the risk of infection has emerged. Here, we review evidence that supports the use of the host immune responses against sand fly salivary proteins to estimate risk of infection. We also discuss how the use of recombinant salivary proteins can optimize serological surveys and provide guidance for the implementation of specific measures for disease control in endemic areas.

During Leishmania transmission, sand fly saliva is co-inoculated with parasites into the skin of the mammalian host. Sand fly saliva consists of roughly thirty different salivary proteins, many with known roles linked to blood feeding facilitation. Apart from the anti-hemostatic capacity of saliva, several sand fly salivary proteins have been shown to be immunogenic. Immunization with a single salivary protein or exposure to uninfected bites was shown to result in a protective immune response against leishmaniasis. Antibodies to saliva were not required for this protection. A strong body of evidence points to the role for salivaspecific T cells producing IFN-gamma in the form of a delayed-type hypersensitivity reaction at the bite site as the main protective response. Herein, we review the immunity to sand fly salivary proteins in the context of its vector parasite host combinations and their vaccine potential, as well as some recent advances to shed light on the mechanism of how an immune response to sand fly saliva protects against leishmaniasis.

TI Human NK cell lytic granules and regulation of their exocytosis SO FRONTIERS IN IMMUNOLOGY LA English DT Review DE NK cells; cytotoxic lymphocytes; lytic granules; lysosomes; cytotoxicity; exocytosis AB Natural killer (NK) cells form a subset of lymphocytes that play a key role in immuno-surveillance and host defense against cancer and viral infections. They recognize stressed cells through a variety of germline-encoded activating cell surface receptors and utilize their cytotoxic ability to eliminate abnormal cells. Killing of target cells is a complex, multi stage process that concludes in the directed secretion of lytic granules, containing perforin and granzymes, at the immunological synapse. Upon delivery to a target cell, perforin mediates generation of pores in membranes of target cells, allowing granzymes to access target cell cytoplasm and induce apoptosis. Therefore, lytic granules of NK cells are indispensable for normal NK cell cytolytic function. Indeed, defects in lytic granule secretion lead or are related to serious and often fatal diseases, such as familial hemophagocytic lymphohistiocytosis (FHL) type 2-5 or Griscelli syndrome type 2. A number of reports highlight the role of several proteins involved in lytic granule release and NK cell-mediated killing of tumor cells. This review focuses on lytic granules of human NK cells and the advancements in understanding the mechanisms controlling their exocytosis.

TI A NET outcome SO FRONTIERS IN IMMUNOLOGY LA English DT Article DE neutrophil; apoptosis; necrosis; phagocytosis; inflammation AB Neutrophils constitute a critical part of innate immunity and are well known for their ability to phagocytose and kill invading microorganisms. The microbicidal processes employed by neutrophils are highly effective at killing most ingested bacteria and fungi. However, an alternative non-phagocytic antimicrobial mechanism of neutrophils has been proposed whereby microorganisms are eliminated by neutrophil extracellular traps (NETs). NETs are comprised of DNA, histones, and antimicrobial proteins extruded by neutrophils during NETosis, a cell death pathway reported to be distinct from apoptosis, phagocytosis-induced cell death, and necrosis. Although multiple laboratories have reported NETs using various stimuli in vitro, the molecular mechanisms involved in this process have yet to be definitively elucidated, and many questions regarding the formation and putative role or function of NETs in innate host defense remain unanswered. It is with these questions in mind that we provide some reflection and perspective on NETs and NETosis.

TI KIR2DL4 (CD158d). an activation receptor for HLA-G SO FRONTIERS IN IMMUNOLOGY LA English DT Review DE NK; KIR; HLA-G; pregnancy AB KIR2DL4 is an unusual killer cell immunoglobulin-like receptor (KIR) family member in terms of its structure, expression, cellular localization, and signaling properties. The most conserved KIR in evolution, it is referred to as a framework KIR gene and is expressed by all natural killer (NK) cells and a subset of T cells. Although it has a long cytoplasmic tail that is typical of inhibitory KIR, engagement of this receptor results in the activation of NK cells, not for cytotoxicity, but for cytokine and chemokine secretion. Unlike all other KIRs, which are expressed on the surface of NK cells, KIR2DL4 resides in endosomes. It signals from this intracellular site fora proinflammatory and proangiogenic response, using a novel endosomal signaling pathway that involves the serine/threonine kinases DNA-PKcs and Akt. The only known ligand of KIR2DL4 is HLA-G. Soluble HLA-G accumulates in KIR2DL4(+) endosomes. Unlike classical HLA molecules that serve as ligands for other KIR family members, in healthy individuals, HLA-G expression is restricted to the fetal trophoblast cells that invade the maternal decidua during early pregnancy. Since NK cells constitute the predominant lymphocyte subset at this site, the proinflammatory/proangiogenic outcome of the interaction between KIR2DL4 and soluble HLA-G supports a role for KIR2DL4 in the extensive remodeling of the maternal vasculature during the early weeks of pregnancy.

However, longitudinal changes of human immune cells with age have not yet been adequately addressed. To test the hypothesis that regeneration of lymphocytes and monocytes is robust throughout most of adult life until advanced age, we examined six leukapheresis donors (3 young and 3 middle-aged/old) who donated approximately 10% of their peripheral blood mononuclear cells (PBMC) every other month over 3-5 years. We found the number of both lymphocytes and monocytes were quite stable in the blood of all six donors. As expected, young donors had more T cell receptor excision circles (TRECs), CD31(+) cells (CD4 only) and longer telomeres in T cells than did the middle-aged donors. Interestingly, more variation in TREC number, V beta usages, and telomere lengths were observed in young donors during the 3-5 years course of donation whereas the middle-aged/old donors showed a rather striking stability in these measurements. This may reflect a more prominent role of thymic output in T cell regeneration in young than in middle-aged/old donors. Together, these findings provide an in vivo glimpse into the homeostasis of lymphocytes and monocytes in the blood at different ages, and support the notion that regeneration of lymphocytes and monocytes is robust throughout adult life up to the early 70s.

However, recent studies have suggested that at least some chemokines may also interfere with infectious agents directly. Antimicrobial chemokines tend to contain amphipathic alpha helical secondary structure, and broad-spectrum activity against both Gram-positive and Gram negative bacteria, as well as fungi. Conversely, several bacteria have been identified that possess mechanisms for specifically blocking the antimicrobial activities of chemokines. Although the precise mechanisms by which chemokines and microbes disarm one another in vitro remain unknown, there is now emerging evidence in vivo that such interactions may be biologically significant. More research will be needed to determine whether chemokines with direct antimicrobial activity may be translated into a novel class of antibiotics.

In alloHCT, different immune cell types mediate beneficial graft-versus-tumor (GvT) effects, regulate detrimental graft-versus-host disease (GvHD), and are required for protection against infections. Today, the "good" (GvT effector cells and memory cells conferring protection) cannot be easily separated from the "bad" (GvHD-causing cells), and alloHCT remains a hazardous medical modality. The transplantation of hematopoietic stem cells into an immunosuppressed patient creates a delicate environment for the reconstitution of donor blood and immune cells in co-existence with host cells. Immunological reconstitution determines to a large extent the immune status of the allo-transplanted host against infections and the recurrence of cancer, and is critical for long-term protection and survival after clinical alloHCT. Animal models continue to be extremely valuable experimental tools that widen our understanding of, for example, the dynamics of post-transplant hematopoiesis and the complexity of immune reconstitution with multiple ways of interaction between host and donor cells. In this review, we discuss the rat as an experimental model of HCT between allogeneic individuals. We summarize our findings on lymphocyte reconstitution in transplanted rats and illustrate the disease pathology of this particular model. We also introduce the rat skin explant assay, a feasible alternative to in vivo transplantation studies. The skin explant assay can be used to elucidate the biology of graft-versus-host reactions, which are known to have a major impact on immune reconstitution, and to perform genome-wide gene expression studies using controlled combinations of minor and major histocompatibility between the donor and the recipient.

TI Pathways of cell cell transmission of HTLV-1 SO FRONTIERS IN MICROBIOLOGY LA English DT Review DE retrovirus; HTLV-1; cell cell transmission; HTLV-1 infectivity; T cell; antigen-presenting cells; HTLV-2; virological synapse AB The deltaretroviruses human T cell lymphotropic virus type 1 (HTLV-1) and human T cell lymphotropic virus type 2 (HTLV-2) have long been believed to differ from retroviruses in other genera by their mode of transmission. While other retroviruses were thought to primarily spread by producing cell-free particles that diffuse through extracellular fluids prior to binding to and infecting target cells, HTLV-1 and HTLV-2 were believed to transmit the virus solely by cell cell interactions. This difference in transmission was believed to reflect the fact that, relative to other retroviruses, the cell-free virions produced by HTLV-infected cells are very poorly infectious. Since HTLV-1 and HTLV-2 are primarily found in T cells in the peripheral blood, spread of these viruses was believed to occur between infected and uninfected T cells, although little was known about the cellular and viral proteins involved in this interaction. Recent studies have revealed that the method of transmission of HTLV is not unique: other retroviruses including human immunodeficiency virus (HIV) are also transmitted from cell-to-cell, and this method is dramatically more efficient than cell-free transmission. Moreover, cell cell transmission of HTLV-1, as well as HIV, can occur following interactions between dendritic cells and T cells, as well as between T cells. Conversely, other studies have shown that cell-free HTLV-1 is not as poorly infectious as previously thought, since it is capable of infecting certain cell types. Here we summarize the recent insights about the mechanisms of cell cell transmission of HTLV-1 and other retroviruses. We also review in vitro and in vivo studies of infection and discuss how these finding may relate to the spread of HTLV-1 between individuals.

Hu, Duosha Yarchoan, Robert TI Clinical manifestations of Kaposi sarcoma herpesvirus lytic activation: rnulticentric Castleman disease (KSHV-MCD) and the KSHV inflammatory cytokine syndrome SO FRONTIERS IN MICROBIOLOGY LA English DT Review DE Kaposi sarcoma-associated hetpesvirus; human herpesvirus 8; multicentric Castleman disease; KSHV inflammatory cytokine syndrome; interleukin-6; human immunodeficiency virus AB Soon after the discovery of Kaposi sarcoma (KS)-associated herpesvirus (KSHV), it was appreciated that this virus was associated with most cases of multicentric Castleman disease (MCD) arising in patients infected with human immunodeficiency virus. It has subsequently been recognized that KSHV-MCD is a distinct entity from other forms of MCD. Like MCD that is unrelated to KSHV, the clinical presentation of KSHV-MCD is dominated by systemic inflammatory symptoms including fevers, cachexia, and laboratory abnormalities including cytopenias, hypoalbuminemia, hyponatremia, and elevated C-reactive protein. Pathologically KSHV-MCD is characterized by polyclonal, IgM-lambda restricted plasmacytoid cells in the intrafollicular areas of affected lymph nodes. A portion of these cells are infected with KSHV and a sizable subset of these cells express KSHV lytic genes including a viral homolog of interleukin-6 (vIL-6). Patients with KSHV-MCD generally have elevated KSHV viral loads in their peripheral blood. Production of vIL-6 and induction of human (h) IL-6 both contribute to symptoms, perhaps in combination with overproduction of MO and other cytokines. Until recently, the prognosis of patients with KSHV-MCD was poor. Recent therapeutic advances targeting KSHV-infected B cells with the anti-CD20 monoclonal antibody rituximab and utilizing KSHV enzymes to target KSHV-infected cells have substantially improved patient outcomes. Recently another KSHV-associated condition, the KSHV inflammatory cytokine syndrome (KICS) has been described. Its clinical manifestations resemble those of KSHV-MCD but lymphadenopathy is not prominent and the pathologic nodal changes of KSHV MCD are absent. Patients with KICS exhibit elevated KSHV viral loads and elevation of vIL-6, homolog of human interleukin-6 and IL-10 comparable to those seen in KSHV-MCD; the cellular origin of these is a matter of investigation. KICS may contribute to the inflammatory symptoms seen in some patients with severe KS or primary effusion lymphoma. Additional research is needed to better define the clinical spectrum of KICS and its relationship to KSHV-MCD. In additional, research is needed to better understand the pathogenesis and epidemiology of both KICS and KSHV-MCD, as well as the optimal therapy for both of these disorders.

TI An assembly model of Rift Valley fever virus SO FRONTIERS IN MICROBIOLOGY LA English DT Article DE bunyavirus assembly; protein structure prediction; hybrid modeling; multi-body refinement; multi-resolution registration AB Rift Valley fever virus (RVFV) is a bunyavirus endemic to Africa and the Arabian Peninsula that infects humans and livestock. The virus encodes two glycoproteins, Gn and Gc, which represent the major structural antigens and are responsible for host cell receptor binding and fusion. Both glycoproteins are organized on the virus surface as cylindrical hollow spikes that cluster into distinct capsomers with the overall assembly exhibiting an icosahedral symmetry. Currently, no experimental three-dimensional structure for any entire bunyavirus glycoprotein is available. Using fold recognition, we generated molecular models for both RVFV glycoproteins and found significant structural matches between the RVFV Gn protein and the influenza virus hemagglutinin protein and a separate match between RVFV Gc protein and Sindbis virus envelope protein El. Using these models, the potential interaction and arrangement of both glycoproteins in the RVFV particle was analyzed, by modeling their placement within the cryo-electron microscopy density map of RVFV. We identified four possible arrangements of the glycoproteins in the virion envelope. Each assembly model proposes that the ectodomain of Gn forms the majority of the protruding capsomer and that Gc is involved in formation of the capsomer base. Furthermore, Gc is suggested to facilitate intercapsomer connections. The proposed arrangement of the two glycoproteins on the RVFV surface is similar to that described for the alphavirus El-E2 proteins. Our models will provide guidance to better understand the assembly process of phleboviruses and such structural studies can also contribute to the design of targeted antivirals.

Previously, recombinant human immunodeficiency virus type 1 (HIV-1) strains were constructed that express a fluorescent reporter, either enhanced green fluorescent protein, or DsRed, which allow the monitoring of HIV-1-infected cells by flow cytometry. The present study further investigated the potential of these recombinant viruses in terms of whether the HIV-1 fluorescent reporters would be helpful in evaluating viral replication based on fluorescence intensity. When primary CD4(+) T cells were infected with recombinant viruses, the fluorescent reporter intensity measured by flow cytometry was associated with the level of CD4 downmodulation and Gag p24 expression in infected cells. Interestingly, some HIV-1-infected cells, in which CD4 was only moderately down-modulated, were reporter-positive but Gag p24-negative. Furthermore, when the activation status of primary CD4(+) T cells was modulated by T cell receptor-mediated stimulation, we confirmed the preferential viral production upon strong stimulation and showed that the intensity of the fluorescent reporter within a proportion of HIV-1-infected cells was correlated with the viral replication level. These findings indicate that a fluorescent reporter encoded within HIV-1 is useful for the sensitive detection of productively infected cells at different stages of infection and for evaluating cell-associated viral replication at the single cell level.

CA NISC Comparative Sequencing Prog TI Somatic populations of PGT135-137 HIV-1-neutralizing antibodies identified by 454 pyrosequencing and bioinfornnatics SO FRONTIERS IN MICROBIOLOGY LA English DT Article DE antibody bioinformatics; high-throughput sequencing; HIV-1; immunity; N-linked glycan AB Select HIV-1-infected individuals develop sera capable of neutralizing diverse viral strains. The molecular basis of this neutralization is currently being deciphered by the isolation of HIV-1-neutralizing antibodies. In one infected donor, three neutralizing antibodies, PGT135-137, were identified by assessment of neutralization from individually sorted B cells and found to recognize an epitope containing an N-linked glycan at residue 332 on HIV-1 gp120. Here we use next-generation sequencing and bioinformatics methods to interrogate the B cell record of this donor to gain a more complete understanding of the humoral immune response. PGT135-137-gene family specific primers were used to amplify heavy-chain and light-chain variable-domain sequences. Pyrosequencing produced 141,298 heavy-chain sequences of IGHV4-39 origin and 87,229 light-chain sequences of IGKV3-15 origin. A number of heavy and light-chain sequences of similar to 90% identity to PGT137, several to PGT136, and none of high identity to PGT135 were identified. After expansion of these sequences to include close phylogenetic relatives, a total of 202 heavy-chain sequences and 72 light-chain sequences were identified. These sequences were clustered into populations of 95% identity comprising 15 for heavy chain and 10 for light chain, and a select sequence from each population was synthesized and reconstituted with a PGT137-partner chain. Reconstituted antibodies showed varied neutralization phenotypes for HIV-1 clade A and D isolates. Sequence diversity of the antibody population represented by these tested sequences was notably higher than observed with a 454 pyrosequencing-control analysis on 10 antibodies of defined sequence, suggesting that this diversity results primarily from somatic maturation. Our results thus provide an example of how pathogens like HIV-1 are opposed by a varied humoral immune response, derived from intrinsic mechanisms of antibody development, and embodied by somatic populations of diverse antibodies.

TI Effects of prior knowledge on decisions made under perceptual vs. categorical uncertainty SO FRONTIERS IN NEUROSCIENCE LA English DT Article DE prior probability; expectation; frontoparietal; dorsolateral prefrontal cortex AB Humans use prior knowledge to bias decisions made under uncertainty. In this fMRI study we predicted that different brain dynamics play a role when prior knowledge is added to decisions made under perceptual vs. categorical uncertainty. Subjects decided whether shapes belonged to Category S - smoother or Category B - bumpier - under both uncertainty conditions, with or without prior knowledge cues. When present, the prior knowledge cue, 80/20 or 50/50, indicated that 80 and 20% (or 50 and 50%) were the chances that responding "S" and "B" (or vice versa) would be correct. During perceptual uncertainty, shapes were degraded with noise. During categorical uncertainty, shapes were ambiguous. Adding the 80/20 cue increased activation during perceptual uncertainty in bilateral lateral occipital (LO) cortex and left middle frontal gyrus (MidFG), and decreased activity in bilateral LO cortex during categorical uncertainty. Right MidFG and other frontoparietal regions were active in all conditions. The results demonstrate that left MidFG shows activation changes, suggestive of an influence on visual cortex, that depend on the factor that makes the decisions difficult. When sensory evidence is difficult to perceive, prior knowledge increases visual cortical activity. When the sensory evidence is easy to perceive but difficult to interpret, prior knowledge decreases visual cortical activity.

Several studies have explored the contribution of released dopamine (DA) or responses of DA neurons on reward seeking using rewards such as food, water, and sex. Phasic DA signals evoked by rewards or conditioned reward predictors are well documented, as are modulations of these signals by such parameters as reward magnitude, probability, and deviation of actually occurring from expected rewards. Less attention has been paid to DA neuron firing and DA release in response to aversive stimuli, and the prediction and avoidance of punishment. In this review, we first focus on DA changes in response to aversive stimuli as measured by microdialysis and voltammetry followed by the change in electrophysiological signatures by aversive stimuli and fearful events. We subsequently focus on the role of DA and effect of DA manipulations on signaled avoidance learning, which consists of learning the significance of a warning cue through Pavlovian associations and the execution of an instrumental avoidance response. We present a coherent framework utilizing the data on microdialysis, voltammetry, electrophysiological recording, electrical brain stimulation, and behavioral analysis. We end by outlining current gaps in the literature and proposing future directions aimed at incorporating technical and conceptual progress to understand the involvement of reward circuit on punishment based decisions.

As second messenger of many signaling pathways, Ca2+ as been shown to regulate neuronal gene expression, energy production, membrane excitability, synaptogenesis, synaptic transmission, and other processes underlying learning and memory and cell survival. The flexibility of Ca2+ signaling is achieved by modifying cytosolic Ca2+ concentrations via regulated opening of plasma membrane and subcellular Ca2+ sensitive channels. The spatiotemporal patterns of intracellular Ca2+ signals, and the ultimate cellular biological outcome, are also dependent upon termination mechanism, such as Ca2+ buffering, extracellular extrusion, and intra-organelle sequestration. Because of the central role played by Ca2+ in neuronal physiology, it is not surprising that even modest impairments of Ca2+ homeostasis result in profound functional alterations. Despite their heterogeneous etiology neurodegenerative disorders, as well as the healthy aging process, are all characterized by disruption of Ca2+ homeostasis and signaling. In this review we provide an overview of the main types of neuronal Ca2+ channels and their role in neuronal plasticity. We will also discuss the participation of Ca2+ signaling in neuronal aging and degeneration.

Such mAbs react with both species-specific epitopes and epitopes conserved between species. mAbs against proteins involved in extracellular proteolysis, including plasminogen activators urokinase plasminogen activator (uPA), tissue-type plasminogen activator (tPA), their inhibitor PAI-1, the uPA receptor (uPAR), two matrix metalloproteinases (MMP9 and MMP14), as well as the collagen internalization receptor uPARAP have been developed. The inhibitory mAbs against uPA and uPAR block plasminogen activation and thereby hepatic fibrinolysis in vivo. Wound healing, another plasmin-dependent process, is delayed by an inhibitory mAb against uPA in the adult mouse. Thromboembolism can be inhibited by anti-PAI-1 mAbs in vivo. In conclusion, function-blocking mAbs are well-suited for targeted therapy in mouse models of different diseases, including cancer.

TI Endocannabinoid-dopamine interactions in striatal synaptic plasticity SO FRONTIERS IN PHARMACOLOGY LA English DT Review DE long-term depression; CBI; serotonin; 5-HT1b; adenosine; Parkinson's disease; medium spiny neuron AB The nigrostriatal dopaminergic system is implicated in action control and learning. A large body of work has focused on the contribution of this system to modulation of the corticostriatal synapse, the predominant synapse type in the striatum. Signaling through the D2 dopamine receptor is necessary for endocannabinoid-mediated depression of corticostriatal glutamate release. Here we review the known details of this mechanism and discuss newly discovered signaling pathways interacting with this system that ultimately exert dynamic control of cortical input to the striatum and striatal output. This topic is timely with respect to Parkinson's disease given recent data indicating changes in the striatal endocannabinoid system in patients with this disorder.

TI Apolipoprotein mimetic peptides: a new approach for the treatment of asthma SO FRONTIERS IN PHARMACOLOGY LA English DT Review DE asthma; apolipoprotein E; apolipoprotein A-I; apolipoprotein E mimetic peptide; apolipoprotein A-I mimetic peptide AB New treatments are needed for severe asthmatics to improve disease control and avoid severe toxicities associated with oral corticosteroids. We have used a murine model of house dust mite (HDM)-induced asthma to identify steroid-unresponsive genes that might represent targets for new therapeutic approaches for severe asthma. This strategy identified apolipoprotein E as a steroid-unresponsive gene with increased mRNA expression in the lungs of HDM-challenged mice. Furthermore, apolipoprotein E functioned as an endogenous negative regulator of airway hyperreactivity and goblet cell hyperplasia in experimental HDM-induced asthma. The ability of apolipoprotein E, which is expressed by lung macrophages, to attenuate AHR, and goblet cell hyperplasia is mediated by low density lipoprotein (LDL) receptors expressed by airway epithelial cells. Consistent with this, administration of an apolipoprotein E mimetic peptide, corresponding to amino acids 130-149 of the LDL receptor-binding domain of the holo-apoE protein, significantly reduced AHR and goblet cell hyperplasia in HDM-challenged apoE(-/-) mice.These findings identified the apolipoprotein E - LDL receptor pathway as a new druggable target for asthma that can be activated by administration of apoE-mimetic peptides. Similarly, apolipoprotein A-I may have therapeutic potential in asthma based upon its anti-inflammatory, anti-oxidative, and anti-fibrotic properties. Furthermore, administration of apolipoprotein A-I mimetic peptides has attenuated airway inflammation, airway remodeling, and airway hyperreactivity in murine models of experimental asthma. Thus, site-directed delivery of inhaled apolipoprotein E or apolipoprotein A-I mimetic peptides may represent novel treatment approaches that can be developed for asthma, including severe disease.

TI Arterial-ventricular coupling with aging and disease SO FRONTIERS IN PHYSIOLOGY LA English DT Review DE left ventricular function; arterial system; exercise; aging; disease AB Age is the dominant risk factor for cardiovascular diseases. Understanding the coupling between the left ventricle (LV) and arterial system, termed arterial ventricular coupling (E-A/E-LV), provides important mechanistic insights into the complex cardiovascular system and its changes with aging in the absence and presence of disease. E-A/E-LV can be indexed by the ratio of effective arterial elastance (E-A; a measure of the net arterial load exerted on the LV) to left ventricular end-systolic elastance (E-LV; a load-independent measure of left ventricular chamber performance). Age-associated alterations in arterial structure and function, including diameter, wall thickness, wall stiffness, and endothelial dysfunction, contribute to a gradual increase in resting E-A with age. Remarkably there is a corresponding increase in resting E-LV with age, due to alterations to LV remodeling (loss in myocyte number, increased collagen) and function. These age-adaptations at rest likely occur, at least, in response to the age-associated increase in E-A and ensure that E-A/E-LV is closely maintained within a narrow range, allowing for optimal energetic efficiency at the expense of mechanical efficacy. This optimal coupling at rest is also maintained when aging is accompanied by the presence of hypertension, and obesity, despite further increases in E-A and E-LV in these conditions. In contrast, in heart failure patients with either reduced or preserved ejection fraction, E-A/E-LV at rest is impaired. During dynamic exercise, E-A/E-LV decreases, due to an acute mismatch between the arterial and ventricular systems as E-LV increases disproportionate compared to E-A (approximate to 200 vs. 40%), to ensure that sufficient cardiac performance is achieved to meet the increased energetic requirements of the body. However, with advancing age the reduction in E-A/E-LV during acute maximal exercise is blunted, due to a blunted increase E-LV. This impaired E-A/E-LV is further amplified in the presence of disease, and may explain, in part, the reduced cardiovascular functional capacity with age and disease. Thus, although increased stiffness of the arteries itself has important physiological and clinical relevance, such changes also have major implications on the heart, and vice versa, and the manner in the way they interact has important ramifications on cardiovascular function both at rest and during exercise. Examination of the alterations in arterial ventricular coupling with aging and disease can yield mechanistic insights into the pathophysiology of these conditions and increase the effectiveness of current therapeutic interventions.

Even more amazing is the fact that throughout these mitotic cell cycles, the human genome is duplicated once and only once each time a cell divides. If a cell accidentally begins to re-replicate its nuclear DNA prior to cell division, checkpoint pathways trigger apoptosis. And yet, some cells are developmentally programmed to respond to environmental cues by switching from mitotic cell cycles to endocycles, a process in which multiple S phases occur in the absence of either mitosis or cytokinesis. Endocycles allow production of viable, differentiated, polyploid cells that no longer proliferate. What is surprising is that among the 516 (Manning et al., 2002) to 557 (BioMart web site) protein kinases encoded by the human genome, only eight regulate nuclear DNA replication directly. These are Cdk1, Cdk2, Cdk4, Cdk6, Cdk7, Cdc7, Checkpoint kinase-1 (Chk1), and Checkpoint kinase-2. Even more remarkable is the fact that only four of these enzymes (Cdk1, Cdk7, Cdc7, and Chk1) are essential for mammalian development. Here we describe how these protein kinases determine when DNA replication occurs during mitotic cell cycles, how mammalian cells switch from mitotic cell cycles to endocycles, and how cancer cells can be selectively targeted for destruction by inducing them to begin a second S phase before mitosis is complete.

During fibrosis progression, hepatocellular damage and inflammation trigger complex cellular events that result in collagen deposition and the disruption of the normal liver architecture. Hepatic stellate cell activation and transdifferentiation into myofibroblasts are key events in liver fibrogenesis. Research findings from cell culture and animal models have revealed that the Janus kinase-signal transducer and activator of transcription (Jak-STAT) signaling pathway, which can be activated by many cytokines, growth factors, and hormones, plays a critical role in hepatic fibrogenesis. This review summarizes the biological significance of diverse cytokines and their downstream signaling protein STATs in hepatic fibrogenesis.

TI Task difficulty modulates the impact of emotional stimuli on neural response in cognitive-control regions SO FRONTIERS IN PSYCHOLOGY LA English DT Article DE emotion; cognitive control; executive function; emotion-cognition interactions; fMRI; ACC; DLPFC; IFG AB Both heightened reactivity to emotional stimuli and impaired cognitive control are key aspects of depression, anxiety, and addiction. But the impact of emotion on cognitive-control processes, and the factors that modulate this impact, are still not well understood. We examined the effects of threat and reward distracters on the neural correlates of cognitive control using functional MRI (fMRI) and the Multi-Source Interference Task (MSIT). Behaviorally, subjects were slower and less accurate on the more demanding incongruent trials compared to the easier congruent trials. In addition, both threat and reward distracters significantly impaired the speed of responding on incongruent trials relative to the no-distracter condition. At the neural level, we used the incongruent congruent contrast to functionally define four cognitive-control regions of interest (ROIs): anterior cingulate cortex (ACC), left and right inferior frontal gyrus (IFG)/insula, and right dorsolateral prefrontal cortex (DLPFC). A repeated-measures analysis of variance on the extracted contrast values in these ROIs indicated a significant interaction of stimulus salience and task difficulty on the neural response in cognitive-control regions. Specifically, threat distracters significantly decreased the response in cognitive-control regions on incongruent trials, whereas they significantly increased that response on congruent trials, relative to the no-distracter condition. Exploratory analyses of the amygdala response showed a similar interaction of stimulus salience and task difficulty: threat distracters significantly decreased the amygdala response only on incongruent trials. Overall, our results suggest that the impact of emotional distracters on the neural response in cognitive-control regions as well as in the amygdala is modulated by task difficulty, and add to our understanding of the factors that determine whether emotion enhances or impairs cognition.

In the current study, 8- to 11-year-old children (N = 171) learned a sequence of four left and right button presses, LLRR, RRLL, LRLR, RLRL, LRRL, and RLLR, which needed to be deduced from feedback because no directional cues were given. One group of children experienced consistent feedback only (deterministic feedback, 100% correct). In this condition, green feedback on the screen indicated that the children had been right when they were right, and red feedback indicated that the children had been wrong when they were wrong. Another group of children experienced inconsistent feedback (stochastic feedback, 85% correct, 15% false), where in some trials, green feedback on the screen could signal that children were right when in fact they were wrong, and red feedback could indicate that they were wrong when in fact they had been right. Independently of age, children's sequence learning in the stochastic condition was initially much lower than in the deterministic condition, but increased gradually and improved with practice. Responses toward positive vs. negative feedback varied with age. Children were increasingly able to understand that they could have been wrong when feedback indicated they were right (self-reflection), but they remained unable to understand that they could have been right when feedback indicated they were wrong (self-assertion).

In two experiments, we investigated the effects of different intermodal attention manipulations on the response of outer hair cells (OHCs), and the control exerted by the MOC efferent system. The effect of the MOCs on OHC activity was characterized by measuring the amplitude and rapid adaptation time course of distortion product otoacoustic emissions (DPOAEs). In the first, DPOAE recordings were compared while participants were reading a book and counting the occurrence of the letter "a" (auditory-ignoring) and while counting either short- or long-duration eliciting tones (auditory-attending). In the second, DPOAEs were recorded while subjects watched muted movies with subtitles (auditory-ignoring/visual distraction) and were compared with DPOAEs recorded while subjects counted the same tones (auditory-attending) as in Experiment 1. In both Experiments 1 and 2, the absolute level of the averaged DPOAEs recorded during the auditory-ignoring condition was statistically higher than that recorded in the auditory-attending condition. Efferent-induced rapid adaptation was evident in all DPOAE contours, under all attention conditions, suggesting that two medial efferent processes act independently to determine rapid adaptation, which is unaffected by attention, and the overall DPOAE level, which is significantly affected by changes in the focus of attention.

Although it is well established that an experimentally induced change in mood state comprises one type of competing process that can impair performance on a subsequent task, no study has investigated whether an emotionally valenced autobiographical memory (AM) also can alter performance on a subsequent task. We therefore examined the effects of AM recall on cognitive performance. Healthy participants (n = 20 per experiment) recalled AMs in response to positive, negative, and neutral cue words. Following each AM participants completed a simple perceptual task (Experiment 1) or solved moderately difficult subtraction problems (Experiment 2). In Experiment 1 participants performed less accurately following exposure to positive or negative versus neutral cue words (ps < 0.001), and also were less accurate following negative versus positive cue words (p < 0.001). In Experiment 2, in contrast, no difference in accuracy or response times reached statistical significance. Performance accuracy even trended toward being higher following exposure to negative versus neutral cue words (p = 0.08). The results of Experiment 1 suggested that recalling emotionally salient AMs reduces the attention directed toward a simple continuous performance task administered immediately following the AM task, conceivably due to persistent contemplation of the AM. The negative results of Experiment 2 suggested that the effect of AMs on attention was attenuated, however, by increasing the difficulty of the subsequent task. Our results have implications for patients with major depressive disorder (MDD), as performing cognitively demanding tasks may allow them to attenuate the impairing effects of negative rumination on cognition.

Results: We carried out single-cell exome sequencing of 66 individual tumor cells from a muscle-invasive bladder transitional cell carcinoma (TCC). Analyses of the somatic mutant allele frequency spectrum and clonal structure revealed that the tumor cells were derived from a single ancestral cell, but that subsequent evolution occurred, leading to two distinct tumor cell subpopulations. By analyzing recurrently mutant genes in an additional cohort of 99 TCC tumors, we identified genes that might play roles in the maintenance of the ancestral clone and in the muscle-invasive capability of subclones of this bladder cancer, respectively. Conclusions: This work provides a new approach of investigating the genetic details of bladder tumoral changes at the single-cell level and a new method for assessing bladder cancer evolution at a cell-population level.

CA G10KCOS TI Tissue sampling methods and standards for vertebrate genomics SO GIGASCIENCE LA English DT Review DE Genome 10K; Sequencing; Vertebrates; Genomics; Tissue sampling; Tissue storage; Cell line; Tissue culture; RNA; DNA AB The recent rise in speed and efficiency of new sequencing technologies have facilitated high-throughput sequencing, assembly and analyses of genomes, advancing ongoing efforts to analyze genetic sequences across major vertebrate groups. Standardized procedures in acquiring high quality DNA and RNA and establishing cell lines from target species will facilitate these initiatives. We provide a legal and methodological guide according to four standards of acquiring and storing tissue for the Genome 10K Project and similar initiatives as follows: four-star (banked tissue/cell cultures, RNA from multiple types of tissue for transcriptomes, and sufficient flash-frozen tissue for 1 mg of DNA, all from a single individual); three-star (RNA as above and frozen tissue for 1 mg of DNA); two-star (frozen tissue for at least 700 mu g of DNA); and one-star (ethanol-preserved tissue for 700 mu g of DNA or less of mixed quality). At a minimum, all tissues collected for the Genome 10K and other genomic projects should consider each species' natural history and follow institutional and legal requirements. Associated documentation should detail as much information as possible about provenance to ensure representative sampling and subsequent sequencing. Hopefully, the procedures outlined here will not only encourage success in the Genome 10K Project but also inspire the adaptation of standards by other genomic projects, including those involving other biota.

Amongst people, case fatality rates range between 40 and 75% and there are no vaccines or treatments approved for human use. A number of species of animals including guinea pigs, hamsters, cats, ferrets, pigs, and African green monkeys have been employed as animal models of human henipavirus infection. Here, we review the development of animal models for henipavirus infection, discuss the pathology and pathogenesis of these models, and assess the utility of each model to recapitulate important aspects of henipavirus-mediated disease seen in humans.

However, the self-renewing cells residing on the basement membrane of the epithelium can give rise to oral squamous cell carcinomas (OSCC), now the sixth most common cancer in the developed world, which is still associated with poor prognosis. This is due, in part, to the limited availability of well-defined culture systems for studying oral epithelial cell biology, which could advance our understanding of the molecular basis of OSCC. Here, we describe methods to successfully isolate large cultures of human oral epithelial cells and fibroblasts from small pieces of donor tissues for use in techniques such as three-dimensional cultures and animal grafts to validate genes suspected of playing a role in OSCC development and progression. Finally, the use of isolated oral epithelial cells in generating iPS cells is discussed which holds promise in the field of oral regenerative medicine.

The etiology of this disease is largely unknown. Our laboratory has developed strategies to investigate the cellular and molecular events leading to HO using clinical specimens that were obtained during irrigation and debridement of musculoskeletal injuries. Our approach enables to study (1) the cell types that are responsible for pathological transformation and ossification, (2) the cell-and tissue-level signaling that induces the pathologic transformation, and (3) the effect of extracellular matrix topography and force transduction on HO progression. In this review, we will report on our findings in each of these aspects of HO etiology and describe our efforts to recapitulate our findings in an animal model for traumatic HO.

Since nearly all cell types respond to TGF-beta, TGF-beta s are well-positioned to integrate cellular responses in the parenchymal and stromal compartments of normal tissues and of tumors, and to mediate cross-talk between the two. Pre-clinical studies have uncovered complex roles for TGF-beta s in tumorigenesis, with tumor suppressive and tumor promoting effects on both compartments. In this review, we discuss the biological activities of TGF-beta that underlie these effects and address some of the mechanisms that determine which type of effect dominates at different stages of the tumorigenic process. Finally, we consider the prospects for therapeutic targeting of TGF-beta in cancer, as a way to simultaneously normalize both the microenvironmental and parenchymal compartments of the tumor, and thus prevent or reverse tumor progression.

While prokaryotic incorporation systems are regularly used, mammalian ones are not: of the nearly 9,000 NMR macromolecular structures currently deposited in the Protein Data Bank, only a handful (<0.5%) were solved with proteins expressed in mammalian systems. This low number of structures is largely a re flection of the difficulty in producing uniformly labeled, mammalian-expressed proteins. This is unfortunate, as many interesting proteins require mammalian cofactors, chaperons, or post-translational modifications such as N-linked glycosylation, and mammalian cells have the necessary machinery to produce them correctly. Here we describe recent advances in mammalian expression, including an efficient adenoviral vector-based system, for the production of isotopically enriched proteins. This system allows for the expression of mammalian proteins and their complexes, including proteins that require post-translational modifications. We describe how this system can produce isotopically labeled N-15 and C-13 post-translationally modified proteins, such as the outer domain of HIV-1 gp120, which has 15 sites of N-linked glycosylation. Selective amino-acid labeling is also described. These developments should reduce barriers to the determination of NMR structures with isotopically labeled proteins from mammalian expression systems.

Consistent with studies in mice, genetic evidence in humans has strongly linked the JAK/STAT pathway to primary immunodeficiencies, infection, autoimmunity and cancers. The following chapter will discuss the key role played by JAKs and STATs in the lymphocytes, with special emphasis on helper T cells, which are not only critical mediators of pathogenic inflammation, but also an outstanding model system for investigating JAK/STAT biology. Recent conceptual and technological advances will be highlighted, particularly those relating to human disease and the generation of JAK/STAT based therapeutics.

The neuronal and functional expression of CB2-Rs in the brain has been much less well characterized in comparison with the expression of the ubiquitous CB1-Rs. CB2-Rs were previously thought to be predominantly expressed in immune cells in the periphery and were traditionally referred to as peripheral CB2-Rs. We and others have now demonstrated the expression of CB2-Rs in neuronal, glial and endothelial cells in the brain, and this warrants a re-evaluation of the CNS effects of CB2-Rs. In the present review we summarize our current understanding of CNR2 genomic structure, its polymorphic nature, subtype specificity, from mice to human subjects, and its variants that confer vulnerabilities to neuropsychiatric disorders beyond neuro-immuno-cannabinoid activity.

Content-Based Image Retrieval (CBIR) is an active research field and has drawn attention in recent years. It is a technique to organize and search image archives by their visual content. iris a multi-discipline field that integrates technologies from computer vision, machine learning, information retrieval, human-machine interaction, database systems, and data mining. CBIR consists of four main components: database and indexing,,feature extraction, query formation and interface, and similarity measures. The applications of CBIR? to the medical field include PACS integration, image annotation/codification, computer-aided diagnosis, case-based reasoning, and teaching tools. This chapter intends to disseminate the CBIR techniques to their applications to medical image management and analysis and to attract greater interest from various research communities to advance research in this field.

The proposed method unifies domains of anatomical and functional images (PET-CT), represents them in a product lattice, and performs simultaneous delineation of regions based on a random walk image segmentation. In addition, we propose a simple yet efficient object/background seed localization method, where background and foreground object cues are automatically obtained from PET images and propagated onto the corresponding anatomical images (CT). In our experiments, abnormal anatomies on PET-CT images from human subjects are segmented synergistically by the proposed fully automatic co-segmentation method with high precision (mean DSC of 91.44%) in seconds (avg. 40 seconds).

We propose a fully automated method to detect acute vertebral body fractures on trauma CT studies. The spine is first segmented and partitioned into vertebrae. Then the cortical shell of the vertebral body is extracted using deformable dual-surface models. The extracted cortical shell is unwrapped onto a 2D map effectively converting a complex 3D fracture detection problem into a pattern recognition problem of fracture lines on a 2D plane. Twenty-eight features are computed for each fracture line and sent to a committee of support vector machines for classification. The system was tested on 18 trauma CT datasets and achieved 95.3% sensitivity and 1.7 false positives per case by leave-one-out cross validation.

Our model is based on the Tofts dual-compartment model for the description of tracer kinetics and the observed time series from DCE-MRI is treated as a Gaussian stochastic process. The parameter estimation is done through a maximum likelihood approach and we propose a variant of the coordinate descent method to solve this likelihood maximization problem. The new model was shown to outperform a baseline method on simulated data. Parametric maps generated on prostate DCE data with the new model also provided better enhancement of tumors, lower intensity on false positives, and better boundary delineation when compared with the baseline method. New statistical parameter maps from the process model were also found to be informative, particularly when paired with the PK parameter maps.

The marginal artery of the colon, also known as the marginal artery of Drummond, is the blood vessel that connects the inferior mesenteric artery with the superior mesenteric artery. The marginal artery runs parallel to the colon for its entire length, providing the blood supply to the colon. Detecting the marginal artery may benefit computer-aided detection (CAD) of colonic polyp. It can be used to identify teniae coli based on their anatomic spatial relationship. It can also serve as an alternative marker for colon localization, in case of colon collapse and inability to directly compute the endoluminal centerline. This paper proposes an automatic method for marginal artery detection on CTC. To the best of our knowledge, this is the first work presented for this purpose. Our method includes two stages. The first stage extracts the blood vessels in the abdominal region. The eigenvalue of Hessian matrix is used to detect line-like structures in the images. The second stage is to reduce the false positives in the first step. We used two different masks to exclude the false positive vessel regions. One is a dilated colon mask which is obtained by colon segmentation. The other is an eroded visceral fat mask which is obtained by fat segmentation in the abdominal region. We tested our method on a CTC dataset with 6 cases. Using ratio-of-overlap with manual labeling of the marginal artery as the standard-of-reference, our method yielded true positive, false positive and false negative fractions of 89%, 33%, 11%, respectively.

In particular, it may be useful for small bowel path reconstruction and precise localization of small bowel tumors such as carcinoid. Segmentation of the mesenteric vasculature is very challenging, even for manual labeling, because of the low contrast and tortuosity of the small blood vessels. Many vessel segmentation methods have been proposed. However, most of them are designed for segmenting large vessels. We propose a semi-automated method to extract the mesenteric vasculature on contrast-enhanced abdominal CT scans. First, the internal abdominal region of the body is automatically identified. Second, the major vascular branches are segmented using a multi-linear vessel tracing method. Third, small mesenteric vessels are segmented using multi-view multi-scale vesselness enhancement filters. The method is insensitive to image contrast, variations of vessel shape and small occlusions due to overlapping. The method could automatically detect mesenteric vessels with diameters as small as 1 mm. Compared with the standard-of-reference manually labeled by an expert radiologist, the segmentation accuracy (recall rate) for the whole mesenteric vasculature was 82.3% with a 3.6% false positive rate.

A non-trivial proportion of the public fungal DNA sequences are, however, compromised in terms of quality and reliability, contributing noise and bias to sequence-borne inferences such as phylogenetic analysis, diversity assessment, and barcoding. In this paper we discuss various aspects and pitfalls of sequence quality assessment. Based on our observations, we provide a set of guidelines to assist in manual quality management of newly generated, near-full-length (Sanger-derived) fungal ITS sequences and to some extent also sequences of shorter read lengths, other genes or markers, and groups of organisms. The guidelines are intentionally non-technical and do not require substantial bioinformatics skills or significant computational power. Despite their simple nature, we feel they would have caught the vast majority of the severely compromised ITS sequences in the public corpus. Our guidelines are nevertheless not infallible, and common sense and intuition remain important elements in the pursuit of compromised sequence data. The guidelines focus on basic sequence authenticity and reliability of the newly generated sequences, and the user may want to consider additional resources and steps to accomplish the best possible quality control. A discussion on the technical resources for further sequence quality management is therefore provided in the supplementary material. C1 [Nilsson, R. Henrik; Hallenberg, Nils; Eriksson, K.

We performed a whole-genome copy number variation (CNV) study on 1,013 cases with ADHD and 4,105 healthy children of European ancestry using 550,000 SNPs. We evaluated statistically significant findings in multiple independent cohorts, with a total of 2,493 cases with ADHD and 9,222 controls of European ancestry, using matched platforms. CNVs affecting metabotropic glutamate receptor genes were enriched across all cohorts (P = 2.1 x 10(-9)). We saw GRM5 (encoding glutamate receptor, metabotropic 5) deletions in ten cases and one control (P = 1.36 x 10(-6)). We saw GRM7 deletions in six cases, and we saw GRM8 deletions in eight cases and no controls. GRM1 was duplicated in eight cases. We experimentally validated the observed variants using quantitative RT-PCR. A gene network analysis showed that genes interacting with the genes in the GRM family are enriched for CNVs in similar to 10% of the cases (P = 4.38 x 10(-10)) after correction for occurrence in the controls. We identified rare recurrent CNVs affecting glutamatergic neurotransmission genes that were overrepresented in multiple ADHD cohorts.

These laws facilitated the enhancement of the capacity to detect and respond effectively to significant public health threats. One of the more significant preparedness initiatives pertains to planning for and responding to an influenza pandemic. Within the development of a pandemic plan, much consideration needs to be focused within the areas of communication, mass prophylaxis and immunization, quarantine, isolation, social distancing, and volunteer management. To ensure continual improvement and identify vulnerabilities, plans must be tested with well-designed exercises. The 2009-2010 H1N1 pandemic event gave local health departments (LHDs) the opportunity to implement their pandemic plans within their communities on a large scale. Similar to an exercise, the real event unveiled strengths and improvement needs at the local level. This chapter provides considerations on how to develop and exercise pandemic plans along with providing the lessons learned from the 2009-2010 H1N1 pandemic based on experiences in the field. Through continuous improvement of pandemic plans, LHDs will ultimately empower communities to be more resilient during the next pandemic event.

Because ricin can serve as a particularly well-characterized model of tissue damage, and the host response to that damage, studies of the mechanisms of ricin toxicity may have more general applicability. For example, our studies of the molecular mechanisms underlying the development of ricin-induced hypoglycemia may help elucidate the relationship of type II diabetes, insulin resistance, and inflammation. Studies in non-human primates are most relevant for testing and developing agents having clinical utility. But these animals are expensive and limited in quantity, and so rodents are used for most mechanistic studies.

TI A role for RNA post-transcriptional regulation in satellite cell activation SO SKELETAL MUSCLE LA English DT Article DE Satellite cell; RNA post-transcriptional regulation; microRNA AB Background: Satellite cells are resident skeletal muscle stem cells responsible for muscle maintenance and repair. In resting muscle, satellite cells are maintained in a quiescent state. Satellite cell activation induces the myogenic commitment factor, MyoD, and cell cycle entry to facilitate transition to a population of proliferating myoblasts that eventually exit the cycle and regenerate muscle tissue. The molecular mechanism involved in the transition of a quiescent satellite cell to a transit-amplifying myoblast is poorly understood. Methods: Satellite cells isolated by FACS from uninjured skeletal muscle and 12 h post-muscle injury from wild type and Syndecan-4 null mice were probed using Affymetrix 430v2 gene chips and analyzed by Spotfire(tm) and Ingenuity Pathway analysis to identify gene expression changes and networks associated with satellite cell activation, respectively. Additional analyses of target genes identify miRNAs exhibiting dynamic changes in expression during satellite cell activation. The function of the miRNAs was assessed using miRIDIAN hairpin inhibitors. Results: An unbiased gene expression screen identified over 4,000 genes differentially expressed in satellite cells in vivo within 12 h following muscle damage and more than 50% of these decrease dramatically. RNA binding proteins and genes involved in post-transcriptional regulation were significantly over-represented whereas splicing factors were preferentially downregulated and mRNA stability genes preferentially upregulated. Furthermore, six computationally identified miRNAs demonstrated novel expression through muscle regeneration and in satellite cells. Three of the six miRNAs were found to regulate satellite cell fate. Conclusions: The quiescent satellite cell is actively maintained in a state poised to activate in response to external signals. Satellite cell activation appears to be regulated by post-transcriptional gene regulation.

TI Alkaloids from single skins of the Argentinian toad Melanophryniscus rubriventris (ANURA, BUFONIDAE): An unexpected variability in alkaloid profiles and a profusion of new structures SO SPRINGERPLUS LA English DT Article DE Alkaloids; Gas chromatography-mass spectrometry; Melanophryniscus Toads; Reproduction; Sequestration AB GC-MS analysis of single-skins of ten Melanophryniscus rubriventris toads (five collections of two toads each) captured during their breeding season in NW Argentina has revealed a total of 127 alkaloids of which 56 had not been previously detected in any frog or toad. Included among these new alkaloids are 23 new diastereomers of previously reported alkaloids. What is particularly distinguishing about the alkaloid profiles of these ten collections is the occurrence of many of the alkaloids, whether known or new to us, in only one of the ten skins sampled, despite two skins being obtained from each breeding site of the five populations. Many of the alkaloids are of classes known to have structures with branched-chains (e.g. pumiliotoxins and tricyclic structures) that are considered to derive from dietary mites. A large number of previously reported and new alkaloids are also of unclassified structures. Only a very few 3,5-disubstituted-indolizidine or -pyrrolizidine alkaloids are observed that have a straight-chain carbon skeleton and are likely derived from ant prey. The possible relationship of these collections made during the toad's brief breeding episodes to sequestration of dietary arthropods and individual alkaloid profiles is discussed. C1 [Garraffo, H.

TI Salivary gland organogenesis SO WILEY INTERDISCIPLINARY REVIEWS-DEVELOPMENTAL BIOLOGY LA English DT Article AB Our understanding of vertebrate salivary gland organogenesis has been largely informed by the study of the developing mouse submandibular gland (SMG), which will be the major focus of this review. The mouse SMG has been historically used as a model system to study epithelial mesenchymal interactions, growth factor extracellular matrix (ECM) interactions, and branching morphogenesis. SMG organogenesis involves interactions between a variety of cell types and their stem/progenitor cells, including the epithelial, neuronal, and mesenchymal cells, and their ECM microenvironment, or niche. Here, we will review recent literature that provides conceptual advances in understanding the molecular mechanisms of salivary gland development. We will describe SMG organogenesis, introduce the model systems used to study development, and outline the key signaling pathways and cellular processes involved. We will also review recent research focusing on the identification of stem/progenitor cells in the SMG and how they are directed along a series of cell fate decisions to form a functional gland. The mechanisms that drive SMG organogenesis provide a template to regenerate functional salivary glands in patients who suffer from salivary hypofunction due to irreversible glandular damage after irradiation or removal of tumors. Additionally, these mechanisms may also control growth and development of other organ systems. (C) 2011 Wiley Periodicals, Inc.

While lung cancer risk has been linked to the household use of bituminous coal, no study has comprehensively evaluated the risk of lung cancer associated with the mining of this coal in Xuanwei. In Xuanwei, coal is typically extracted from underground mines, without ventilation, and transported to the surface using carts powered by manpower or electricity. C1 [Hosgood, H.

Here we show that MG-2477 inhibited tubulin polymerization and caused cells to arrest in metaphase. The detailed mechanism of action of MG-2477 was investigated in a non-small cell lung carcinoma cell line (A549). Treatment of A549 cells with MG-2477 caused the cells to arrest in the G2/M phase of the cell cycle, with a concomitant accumulation of cyclin B. Moreover, the compound induced autophagy, which was followed at later times by apoptotic cell death. Autophagy was detected as early as 12 h by the conversion of microtubule associated protein 1 light chain 3 (LC3-I) to LC3-II, following cleavage and lipid addition to LC3-I. After 48 h of MG-2477 exposure, phosphatidylserine externalization on the cell membrane, caspase-3 activation, and PARP cleavage occurred, revealing that apoptotic cell death had begun. Pharmacological inhibition of autophagy with 3-methyladenine or bafilomycin A1 increased apoptotic cell death, suggesting that the autophagy caused by MG-2477 played a protective role and delayed apoptotic cell death. Additional studies revealed that MG-2477 inhibited survival signaling by blocking activation of Akt and its downstream targets, including mTOR, and FHKR. Treatment with MG-2477 also reduced phosphorylation of mTOR downstream targets p70 ribosomal S6 kinase and 4E-BP1. Overexpression of Akt by transfection with a Myr-Akt vector decreased MG-2477 induced autophagy, indicating that Akt is involved. Taken together, these results indicated that the autophagy induced by MG-2477 delayed apoptosis by exerting an adaptive response following microtubule damage. (C) 2011 Elsevier Inc.

TI Stereoselective urinary MDMA (ecstasy) and metabolites excretion kinetics following controlled MDMA administration to humans SO BIOCHEMICAL PHARMACOLOGY LA English DT Article DE MDMA; Phase I metabolites; Phase II metabolites; Urine; Chiral; Controlled administration ID MASS-SPECTROMETRIC ASSAY; GC-NICI-MS; DESIGNER DRUGS; MAIN METABOLITES; 3,4-METHYLENEDIOXYMETHAMPHETAMINE ECSTASY; STEREOCHEMICAL ANALYSIS; PHASE-I; AMPHETAMINE; ENANTIOMERS; TOXICOLOGY AB The R- and S-enantiomers of racemic 3,4-methylenedioxymethamphetamine (MDMA) exhibit different dose-concentration curves. In plasma, S-MDMA was eliminated at a higher rate, most likely due to stereoselective metabolism. Similar data were shown in various in vitro experiments. The aim of the present study was the in vivo investigation of stereoselective elimination of MDMA's phase I and phase II metabolites in human urine following controlled oral MDMA administration. Urine samples from 10 participants receiving 1.0 and 1.6 mg/kg MDMA separated by at least one week were analyzed blind by liquid chromatography-high resolution-mass spectrometry and gas chromatography-mass spectrometry after chiral derivatization with S-heptafluorobutyrylprolyl chloride. R/S ratios at C(max) were comparable after low and high doses with ratios >1 for MDMA, free DHMA, and HMMA sulfate, and with ratios <1 for MDA, free HMMA, DHMA sulfate and HMMA glucuronide. In the five days after the high MDMA dose, a median of 21% of all evaluated compounds were excreted as R-stereoisomers and 17% as S-stereoisomers. Significantly greater MDMA, DHMA, and HMMA sulfate R-enantiomers and HMMA and HMMA glucuronide S-stereoisomers were excreted. No significant differences were observed for MDA and DHMA sulfate stereoisomers. Changes in R/S ratios could be observed over time for all analytes, with steady increases in the first 48 h. R/S ratios could help to roughly estimate time of MDMA ingestion and therefore, improve interpretation of MDMA and metabolite urinary concentrations in clinical and forensic toxicology.

TI Role of resveratrol-induced CD11b(+) Gr-1(+) myeloid derived suppressor cells (MDSCs) in the reduction of CXCR3(+) T cells and amelioration of chronic colitis in IL-10(-/-) mice SO BRAIN BEHAVIOR AND IMMUNITY LA English DT Article DE Inflammation; Resveratrol; Colitis; CXCR3; CD11b(+) and Gr-1(+); MDSCs ID INFLAMMATORY-BOWEL-DISEASE; IMMUNE-RESPONSES; CHEMOKINE RECEPTORS; CROHNS-DISEASE; EXPRESSION; CANCER; ACTIVATION; MECHANISMS; INDUCTION; TOLERANCE AB Resveratrol, a naturally occurring polyphenol has received significant attention as a potent anti-inflammatory agent. Inflammatory bowel disease (IBD) is a chronic intestinal inflammation caused by hyperactivated effector immune cells that produce proinflammatory cytokines. Myeloid derived suppressor cells (MDSCs) are a heterogeneous population characterized by the co-expression of CD11b(+) and Gr-1(+) and have long been known for their immunosuppressive function. We report that resveratrol effectively attenuated overall clinical scores as well as various pathological markers of colitis in IL-10(-/-) mice by down regulating Th1 responses. Resveratrol lessened the colitis-associated decrease in body weight and increased levels of serum amyloid A (SAA), CXCL10 and colon TNF-alpha, IL-6, RANTES, IL-12 and IL-beta concentrations. After resveratrol treatment, the percentage of CXCR3 expressing T cells was decreased in the spleen, mesenteric lymph nodes (MLN), and intestinal lamina propria (LP). However, the percentage and absolute numbers of CD11b(+) and Gr-1(+) cells in the lamina propria (LP) and spleen were increased after resveratrol treatment as compared with the vehicle treatment. Co-culture of resveratrol-induced CD11b(+) Gr-1(+) cells with T cells, attenuated T cell proliferation, and most importantly reduced IFN-gamma and GM-CSF production by LP derived T cells from vehicle treated IL-10(-/-) mice with chronic colitis. The current study suggests that administration of resveratrol into IL-10(-/-) mice induces immunosuppressive CD11b(+) Gr-1(+). MDSCs in the colon, which correlates with reversal of established chronic colitis, and down regulation of mucosal and systemic CXCR3(+) expressing effector T cells as well as inflammatory cytokines in the colon. The induction of immunosuppressive CD11b(+) Gr-1(+) cells by resveratrol during colitis is unique, and suggests an as-yet-unidentified mode of anti-inflammatory action of this plant polyphenol.

The INHANCE pooled data included 22 case-control studies with 14,520 cases and 22,737 controls. Center-specific quartiles among the controls were used for food groups, and frequencies per week were used for single food items. A dietary pattern score combining high fruit and vegetable intake and low red meat intake was created. Odds ratios (OR) and 95% confidence intervals (CI) for the dietary items on the risk of HNC were estimated with a two-stage random-effects logistic regression model. An inverse association was observed for higher-frequency intake of fruit (4th vs. 1st quartile OR = 0.52, 95% CI = 0.43-0.62, p (trend) < 0.01) and vegetables (OR = 0.66, 95% CI = 0.49-0.90, p (trend) = 0.01). Intake of red meat (OR = 1.40, 95% CI = 1.13-1.74, p (trend) = 0.13) and processed meat (OR = 1.37, 95% CI = 1.14-1.65, p (trend) < 0.01) was positively associated with HNC risk. Higher dietary pattern scores, reflecting high fruit/vegetable and low red meat intake, were associated with reduced HNC risk (per score increment OR = 0.90, 95% CI = 0.84-0.97).

In part, the impermeability of the blood brain barrier (BBB) has hindered delivery of chemotherapeutic agents to metastatic tumors in the brain. BBB-permeable chemotherapeutic drugs are being developed, and noninvasively assessing the efficacy of these agents will be important in both preclinical and clinical settings. In this regard, dynamic contrast enhanced (DCE) and diffusion weighted imaging (DWI) are magnetic resonance imaging (MRI) techniques to monitor tumor vascular permeability and cellularity, respectively. In a rat model of metastatic breast cancer, we demonstrate that brain and bone metastases develop with distinct physiological characteristics as measured with MRI. Specifically, brain metastases have limited permeability of the BBB as assessed with DCE and an increased apparent diffusion coefficient (ADC) measured with DWI compared to the surrounding brain. Microscopically, brain metastases were highly infiltrative, grew through vessel co-option, and caused extensive edema and injury to the surrounding neurons and their dendrites. By comparison, metastases situated in the leptomenengies or in the bone had high vascular permeability and significantly lower ADC values suggestive of hypercellularity. On histological examination, tumors in the bone and leptomenengies were solid masses with distinct tumor margins. The different characteristics of these tissue sites highlight the influence of the microenvironment on metastatic tumor growth. In light of these results, the suitability of DWI and DCE to evaluate the response of chemotherapeutic and anti-angiogenic agents used to treat co-opted brain metastases, respectively, remains a formidable challenge.

TI Cellular characterisation of the GCKR P446L variant associated with type 2 diabetes risk SO DIABETOLOGIA LA English DT Article DE Association study; Genetics; Glucokinase; Molecular mechanism ID GLUCOKINASE REGULATORY PROTEIN; RAT PRIMARY HEPATOCYTES; FRUCTOSE 1-PHOSPHATE; LIVER GLUCOKINASE; NUCLEAR EXPORT; IMAGE-ANALYSIS; GLUCOSE; LOCI; TRANSLOCATION; TRIGLYCERIDE AB Translation of genetic association signals into molecular mechanisms for diabetes has been slow. The glucokinase regulatory protein (GKRP; gene symbol GCKR) P446L variant, associated with inverse modulation of glucose- and lipid-related traits, has been shown to alter the kinetics of glucokinase (GCK) inhibition. As GCK inhibition is associated with nuclear sequestration, we aimed to determine whether this variant also alters the direct interaction between GKRP and GCK and their intracellular localisation. Fluorescently tagged rat and human wild-type (WT)- or P446L-GCKR and GCK were transiently transfected into HeLa cells and mouse primary hepatocytes. Whole-cell and nuclear fluorescence was quantified in individual cells exposed to low- or high-glucose conditions (5.5 or 25 mmol/l glucose, respectively). Interaction between GCK and GKRP was measured by sensitised emission-based fluorescence resonance energy transfer (FRET) efficiency. P446L-GKRP had a decreased degree of nuclear localisation, ability to sequester GCK and direct interaction with GCK as measured by FRET compared with WT-GKRP. Decreased interaction was observed between WT-GKRP and GCK at high compared with low glucose, but not between P446L-GKRP and GCK. Rat WT-GKRP and P446L-GKRP behaved quite differently: both variants responded to high glucose by diminished sequestration of GCK but showed no effect of the P446L variant on nuclear localisation or GCK sequestration. Our study suggests the common human P446L-GKRP variant protein results in elevated hepatic glucose uptake and disposal by increasing active cytosolic GCK. This would increase hepatic lipid biosynthesis but decrease fasting plasma glucose concentrations and provides a potential mechanism for the protective effect of this allele on type 2 diabetes risk.

M(1)dG was decreased in controls reporting to consume 14-17 servings/week of fruit and vegetables (mean ratio [MR] = 0.35, CI 0.18-0.69, p < 0.05). Conversely, a non-statistically significant M(1)dG increment was detected in controls consuming 9-18 servings/week of fried food (MR = 1.33, CI 0.88-2.00, p = 0.168). No effect of charcoal-grilled/barbecued food was found. No effect of diet was observed in workers. An association with smoking was observed in controls (MR = 1.88, CI 1.14-3.10, p < 0.05), but not in workers. M(1)dG can induce mutations and/or methylation changes within the promoter regions of cancer-related genes, thus promotion of healthy eating practices should be recommended.

In this report, we investigated the association of total sugars, sucrose, fructose, added sugars, added sucrose and added fructose in the diet with risk of 24 malignancies. Participants (n = 435,674) aged 50-71 years from the NIH-AARP Diet and Health Study were followed for 7.2 years. The intake of individual sugars was assessed using a 124-item food frequency questionnaire (FFQ). Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) in multivariable models adjusted for confounding factors pertinent to individual cancers. We identified 29,099 cancer cases in men and 13,355 cases in women. In gender-combined analyses, added sugars were positively associated with risk of esophageal adenocarcinoma (HRQ5 vs. Q1 : 1.62, 95% CI: 1.07-2.45; p(trend) = 0.01), added fructose was associated with risk of small intestine cancer (HRQ5 vs. Q1 : 2.20, 95% CI: 1.16-4.16; p(trend) = 0.009) and all investigated sugars were associated with increased risk of pleural cancer. In women, all investigated sugars were inversely associated with ovarian cancer. We found no association between dietary sugars and risk of colorectal or any other major cancer. Measurement error in FFQ-reported dietary sugars may have limited our ability to obtain more conclusive findings. Statistically significant associations observed for the rare cancers are of interest and warrant further investigation.

However, experimental animal models designed for evaluating the therapeutic responses of residual disease are mostly lacking. To overcome this deficiency, we have developed a preclinical model that recapitulates the progression for advanced nonsmall cell lung cancer (NSCLC). An archived Lewis lung carcinoma mouse tumor, propagated only through serial in vivo transplantation and never adapted to cell culture, was stably labeled using lentivirus-encoded biomarkers, consistently expressed through an RNA polymerase II promoter. Labeled tumors were inoculated into syngeneic immunocompetent mice to ensure superior tumor-host interactions. Primary tumors were resected on reaching a predetermined size, followed by treatment in a setting akin to postsurgical first-line adjuvant chemotherapy and routine imaging to monitor the progression of pulmonary metastasis. We discovered that efficacious treatment, instead of reducing disease growth rates, significantly prolonged disease-free survival and overall survival. As in the clinic, cisplatin-based regimes were more effective in this model. However, the response of metastases to specific agents could not be predicted from, and often opposed, their effects on subcutaneous "primary" tumors, possibly due to their distinct growth kinetics and host interactions. We here introduce a clinically relevant model of residual metastatic disease that may more accurately predict the therapeutic response of recurrent, metastatic disease.

Study Design and Setting: Subjects were participants from the Erasmus Rucphen Family study, an extended family study among descendants of 20 couples who lived between 1850 and 1900 in a southwest region of the Netherlands and their relatives (n = 1,713). Sensitivity and specificity of self-reported family history were calculated. Results: Sensitivity of self-reported family history was 89.2% for diabetes, 92.2% for hypertension, and 78.4% for overweight when family history based on relatives' self-reported personal health status was used as reference and 70.8% for diabetes, 67.4% for hypertension, and 77.3% for overweight when physician-assessed health status of relatives was used. Sensitivity and specificity of self-reported personal health status were 76.8% and 98.8% for diabetes, 38.9% and 98.0% for hypertension, and 80.9% and 75.7% for overweight, respectively. Conclusion: The accuracy of self-reported family history of diabetes and hypertension is strongly influenced by the accuracy of self-reported personal health status of relatives. Raising awareness of personal health status is crucial to ensure the utility of family history for the assessment of risk and disease prevention. (C) 2012 Elsevier Inc. All rights reserved.

TI Glycosphingolipids Regulate Ameloblastin Expression in Dental Epithelial Cells SO JOURNAL OF DENTAL RESEARCH LA English DT Article DE cell differentiation; enamel; developmental biology; tooth development; cell signaling; gene expression ID GANGLIOSIDE BIOSYNTHESIS; LIPID RAFTS; NERVE; P75; DIFFERENTIATION; PROLIFERATION; RECEPTOR; FAMILY AB Neurotrophin 4 (NT-4) and its receptors regulate the differentiation of ameloblasts in tooth development. Gangliosides, sialic acids that contain glycosphingolipids (GSLs), are involved in a variety of membrane-associated cell physiological functions such as ligand-receptor signal transmission. However, the expression patterns and functions of GSLs during tooth development remain unclear. In this study, we identified strong expressions of GM3 and LacCer in dental epithelium, which give rise to differentiation into enamel-secreting ameloblasts. Exogenous GM3 and LacCer in dental epithelial cells induced the expression of ameloblastin (Ambn), while it was also interesting that GM3 synergistically exerted enhancement of NT-4-mediated Ambn expression. In addition, consistently exogenous GM3 and LacCer in dental epithelial cells induced distinct activation of extracellular signal-regulated kinase 1/2 (ERK1/2), an event upstream of the expression of Ambn. Furthermore, depletion of GSLs from dental epithelial cells by D-threo-1-phenyl-2-decanoylamino-3-morpholino-1-propanol (D-PDMP) inhibited Ambn expression as well as phosphorylation of ERK1/2. In contrast, exogenous addition of GM3 or LacCer rescued the phosphorylation of ERK1/2 repressed by pre-treatment with D-PDMP. Taken together, these results suggest that GM3 and LacCer are essential for NT-4-mediated Ambn expression, and contribute to dental epithelial cell differentiation into ameloblasts.

Materials and Methods: We performed a preclinical phase I trial in dogs with naturally occurring invasive urothelial carcinoma to examine once daily subcutaneous administration of 5-azacitidine in 28-day cycles at doses of 0.10 to 0.30 mg/kg per day according to 2 dose schedules, including days 1 to 5 (28-day cohort) or days 1 to 5 and 15 to 19 (14-day cohort). Clinical efficacy was assessed by serial cystosonography, radiography and cystoscopy. Urinary 5-azacitidine pharmacokinetic analysis was also done. Pretreatment and posttreatment peripheral blood mononuclear cell and invasive urothelial carcinoma DNA, respectively, was analyzed for global and gene specific [CDKN2A (p14ARF)] methylation changes. Results: Enrolled in the study were 19 dogs with naturally occurring invasive urothelial carcinoma. In the 28-day cohort the maximum tolerated dose was 0.20 mg/ kg per day with higher doses resulting in grade 3 or 4 neutropenia in 4 of 6 dogs. In the 14-day cohort the maximum tolerated dose was 0.10 mg/ kg per day with grade 3 or 4 neutropenia seen in 2 of 3 dogs treated at higher doses. No grade 3 or 4 nonhematological toxicity was observed during either dosing schedule. Of 18 dogs evaluable for tumor response partial remission, stable disease and progressive disease were observed in 4 (22.2%), 9 (50.0%) and 4 (22.2%), respectively. Consistent 5-azacitidine levels (205 to 857 ng/ml) were detected in urine. Pretreatment and posttreatment methylation analysis revealed no significant correlation with clinical response. Conclusions: Subcutaneous 5-azacitidine showed promising clinical activity in a canine invasive urothelial carcinoma model, thus meriting further development in humans with urothelial carcinoma.

SO MOLECULAR BIOSYSTEMS LA English DT Editorial Material ID PROTEIN-PROTEIN INTERACTIONS; CONFORMATIONAL ENSEMBLES; MOLECULAR RECOGNITION; DISORDERED PROTEINS; INTRINSIC DISORDER; DRUG DISCOVERY; ALLOSTERY; COOPERATIVITY; SIZE; MECHANISM AB Communication is essential. It is vital between cells in multi-cellular organisms, and within cells. A signaling molecule binds to a receptor protein, and initiates a cascade of dynamic events. Signaling is a multistep pathway, which allows signal amplification: if some of the molecules in a pathway transmit the signal to multiple molecules, the result can be a large number of activated molecules across the cell and multiple reactions. That is how a small number of extracellular signaling molecules can produce a major cellular response. The pathway can relay signals from the extracellular space to the nucleus. How do signals travel efficiently over long-distances across the cell? Here we argue that evolution has utilized three properties: a modular functional organization of the cellular network; sequences in some key regions of proteins, such as linkers or loops, which were pre-encoded by evolution to facilitate signaling among domains; and compact interactions between proteins which is achieved via conformational disorder.

Pathways provide a comprehensive picture of biological processes and allow better understanding of a protein's function within the specific context of its surroundings. Our study pinpoints a few specific pathways significantly enriched in disorder-containing proteins and identifies the role of these proteins within the framework of pathway relationships. Three major categories of relations are shown to be significantly enriched in disordered proteins: gene expression, protein binding and to a lesser degree, protein phosphorylation. Finally we find that relations involving protein activation and to some extent inhibition are characterized by low disorder content.

Progesterone is also known to cause apoptosis while tamoxifen induces growth arrest. Therefore, we attempted to determine whether combined treatment with progesterone and tamoxifen has a synergistic effect on anti-cancer activity. Although progesterone is known to cause apoptosis while tamoxifen induces growth arrest in many cancer cells, the detailed action of progesterone and tamoxifen and the anticancer effect of combined treatment have not been tested in ovarian cancer cells. Therefore, we tested the growth and apoptosis activity of progesterone and tamoxifen and the anticancer effect of combined treatment of progesterone and tamoxifen in ovarian cancer cells. Ovarian cancer cells, PA-1, were treated with progesterone, tamoxifen, or a combination of progesterone and tamoxifen. The anti-cancer effects were investigated by use of flow cytometry, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, DNA fragmentation analysis, and Western blot analysis. We found that 100 mu M progesterone induced typical apoptosis in PA-1 cells. Treatment of PA-1 cells with 10 mu M tamoxifen resulted in an increase in the levels of p21, p27, p16 and phospho-pRb, indicating typical G, arrest. Co-treatment of PA-1 cells with 100 mu M progesterone and 10 mu M tamoxifen resulted in typical apoptosis, similar to that induced by treatment with 100 mu M progesterone alone. These results indicate that progesterone caused apoptosis and tamoxifen induced G, arrest. Combined treatment with tamoxifen and progesterone caused apoptosis similar to that induced by treatment with progesterone alone and had no additional anti-cancer effect in ovarian cancer cells.

All presented initially with severe failure to thrive, polyuria, and polydipsia. Cystinosis was diagnosed at age 1 month to 9 years. Seven patients reached end-stage renal failure at ages ranging from 6.5 to 15 years. Whereas three of the remaining five have renal Fanconi syndrome with proteinuria, two have had kidney failure of varying degrees. Molecular analyses involved an initial multiplex polymerase chain reaction (PCR) to determine the presence or absence of the 57-kb northern European founder deletion in CTNS, followed by sequencing of the ten coding exons of CTNS. Comprehensive mutation analysis verified that none of the 12 patients carried the common 57-kb deletion. We identified four previously reported nucleotide variations associated with cystinosis and five new variants: a 10-kb deletion, three missense variants, and a nucleotide substitution in a potential branch point site of intron 4. This study is the first molecular analysis of Turkish cystinosis patients and provides guidance for the molecular diagnosis of cystinosis in this population.

The Prostate CAncer Therapy Selection study was a prospective, observational multi-site study of men's treatment decision-making process after a diagnosis of local stage prostate cancer. Recruitment occurred in community urology practices in Washington State, hospital-based urology clinics affiliated with the University of Southern California, and Kaiser Permanente in Northern California. Eligible study participants included men over age 21 diagnosed with local stage prostate cancer between May 1, 2005 and December 31, 2006. Fifty-two percent of survey respondents (379) reported using one or more types of CAM. Of the patients, 51% used one CAM method, 26% used two methods, and 23% used three or more methods. The most commonly reported category was mind-body therapies (65%). Only 43% of patients discussed their CAM use with a health professional; of those, 20% informed their primary care physician and 30% told the doctor managing their prostate cancer care. Less than half thought the CAM they used was "very helpful", but a majority thought it was somewhat helpful for their condition. Further research is needed to characterize the goals prostate cancer patients have for CAM, whether the treatments met those goals, and how this translates into the perceived helpfulness of these therapies. The implications of patients not discussing CAM use with health professionals at the time of prostate cancer treatment need further studies.

Image fusion is a popular choice for various image enhancement applications such as overlay of two image products, refinement of image resolutions for alignment, and image combination for feature extraction and target recognition. Since image fusion is used in many geospatial and night vision applications, it is important to understand these techniques and provide a comparative study of the methods. In this paper, we conduct a comparative study on 12 selected image fusion metrics over six multiresolution image fusion algorithms for two different fusion schemes and input images with distortion. The analysis can be applied to different image combination algorithms, image processing methods, and over a different choice of metrics that are of use to an image processing expert. The paper relates the results to an image quality measurement based on power spectrum and correlation analysis and serves as a summary of many contemporary techniques for objective assessment of image fusion algorithms.

We have evaluated colon cancer chemopreventive properties of omeprazole using azoxymethane (AOM)-induced colonic aberrant crypt foci (ACF) in male F344 rats and analyzed cell growth inhibition and apoptosis induction in human colon cancer cells. Five-week-old male F344 rats were fed a control or experimental diet containing two doses of omeprazole (200 and 400 ppm). After one week, all animals were s.c. injected with AOM (15 mg/kg body weight, once weekly for two weeks). Rats continued on experimental diets for seven more weeks before being sacrificed. Colons were histopathologically evaluated for ACF. Human colon cancer HCT-116 and HCA-7 cells treated with omeprazole were evaluated for different markers associated with proliferation and apoptotic markers using Western blot technique. Rats fed with 200 and 400 ppm of omeprazole significantly suppressed total colonic ACF formation (similar to 30%, P<0.001) and showed significant suppression of multi-crypt foci (similar to 30-50%, P<0.05-0.001). Omeprazole produced significant dose-response effects on inhibition of multi-crypt foci (>= 4) Omeprazole treatment in human colon cancer cell lines HCT-116 and HCA-7 cells resulted in induction of p21(wafI/cip1) and decreased the expression of anti-apoptotic proteins Bcl-2, Bcl-X-L, and survivin in a dose-dependent manner. Anticancer properties observed in colon cancer cell lines suggest that omeprazole may induce key signaling molecules of antiproliferation and inhibition of anti-apoptotic proteins.

Whether following a breach in the epithelium or by dissemination from colonized tissues, bacteria interact directly with immune and non-immune host cells. Therefore, it is perhaps not surprising that bacteria implement multiple strategies to circumvent destruction or avoid detection by the host. One such strategy is the ability of bacteria to alter host cell apoptosis or cause other forms of cell death. Although some bacterial pathogens induce or delay cell death and thereby promote disease, bacteria-induced cell death can also be beneficial to the host. This topic is reviewed in the present chapter. C1 [Kobayashi, Scott D.; Rigby, Kevin M.; DeLeo, Frank R.] NIAID, Lab Human Bacterial Pathogenesis, Rocky Mt Labs, NIH, Hamilton, MT 59840 USA.

Microglia utilize Toll-like receptors (TLRs) for pathogen recognition and TLR2 specifically senses conserved motifs of gram-positive bacteria including lipoproteins, lipoteichoic acids, and peptidoglycan (PGN) leading to cytokine/chemokine production. Interestingly, primary microglia derived from TLR2 knockout (KO) mice over-expressed numerous IL-12 family members, including IL-12p40, IL-12p70, and IL-27 in response to intact S. aureus, but not the less structurally complex TLR2 ligands Pam3CSK4 or PGN. The ability of intact bacteria to augment IL-12 family member expression was specific for gram-positive organisms, since numerous gram-negative strains were unable to elicit exaggerated responses in TLR2 KO microglia. Inhibition of SYK or IRAK4 signaling did not impact heightened IL-12 family member production in S. aureus-treated TLR2 KO microglia, whereas PI3K, MAPK, and JNK inhibitors were all capable of restoring exaggerated cytokine expression to wild type levels. Additionally, elevated IL-12 production in TLR2 KO microglia was ablated by a TLR9 antagonist, suggesting that TLR9 drives IL-12 family member production following exposure to intact bacteria that remains unchecked in the absence of TLR2 signaling. Collectively, these findings indicate crosstalk between TLR2 and TLR9 pathways to regulate IL-12 family member production by microglia. The summation of TLR signals must be tightly controlled to ensure the timely cessation and/or fine tuning of cytokine signaling to avoid nonspecific bystander damage due to sustained IL-12 release.

Menin-null mice display early embryonic lethality, and thus imply a critical role for menin in early development. In this study, using the P19 embryonic carcinoma stem cells, we studied menin's role in cell differentiation. Menin expression is induced in P19 cell aggregates by retinoic acid (RA). Menin over-expressing stable clones proliferated in a significantly reduced rate compared to the empty vector harboring cells. RA induced cell death in aggregated menin over-expressing cells. However, in the absence of RA, specific populations of the aggregated menin over-expressing cells displayed the characteristic of an endodermal phenotype by the acquisition of cytokeratin Endo A expression (TROMA-1), a marker for the primitive endoderm, with a concomitant loss of the stem cell marker SSEA-1. Menin's ability to induce endodermal differentiation in specific populations of the aggregated cells in the absence of RA implied that menin could substitute RA by inducing a set of target genes that are RA responsive. Menin over-expressing cells upon aggregation showed a robust expression of RA receptors (RAR), RAR alpha, beta, and gamma relative to the empty vector-harboring cells. Moreover, endodermal differentiation was inhibited by the pan-RAR antagonist Ro41-5253, suggesting that menin could induce endodermal differentiation of uncommitted cells by functionally modulating the RARs.

Mitochondria are key regulators of preconditioning, and most proteins showing an increase in SNO with IPC are mitochondrial. The aim of this study was to address how IPC transduces NO/SNO signaling to mitochondria in the heart. Results: In this study using Langendorff perfused mouse hearts, we found that IPC-induced cardioprotection was blocked by treatment with either N-nitro-L-arginine methyl ester (L-NAME, a constitutive NO synthase inhibitor), ascorbic acid (a reducing agent to decompose SNO), or methyl-beta-cyclodextrin (M beta CD, a cholesterol sequestering agent to disrupt caveolae). IPC not only activated AKT/eNOS signaling but also led to translocation of eNOS to mitochondria. MbCD treatment disrupted caveolar structure, leading to dissociation of eNOS from caveolin-3 and blockade of IPC-induced activation of the AKT/eNOS signaling pathway. A significant increase in mitochondrial SNO was found in IPC hearts compared to perfusion control, and the disruption of caveolae by M beta CD treatment not only abolished IPC-induced cardioprotection, but also blocked the IPC-induced increase in SNO. Innovation: These results provide mechanistic insight into how caveolae/eNOS/NO/SNO signaling mediates cardioprotection induced by IPC. Conclusion: Altogether these results suggest that caveolae transduce eNOS/NO/SNO cardioprotective signaling in the heart. Antioxid. Redox Signal. 16, 45-56.

However, mapping of reads from multiple reference genomes is not possible using a pairwise mapping algorithm. In order to align the reads w.r.t each other and the reference genomes, existing multiple sequence alignment(MSA) methods cannot be used because they do not take into account the position of these short reads with respect to the genome, and are highly inefficient for a large number of sequences. In this paper, we develop a highly scalable parallel algorithm based on domain decomposition, referred to as P-Pyro-Align, to align such a large number of reads from single or multiple reference genomes. The proposed alignment algorithm accurately aligns the erroneous reads, and has been implemented on a cluster of workstations using MPI library. Experimental results for different problem sizes are analyzed in terms of execution time, quality of the alignments, and the ability of the algorithm to handle reads from multiple haplotypes. We report high quality multiple alignment of up to 0.5 million reads. The algorithm is shown to be highly scalable and exhibits super-linear speedups with increasing number of processors.

Biogenic amine-based antidepressants increase BDNF synthesis and activate its signaling pathway through TrkB receptors. Moreover, the antidepressant-like effects of these molecules are abolished in BDNF deficient mice. Glutamate-based drugs, including the NMDA antagonist ketamine, and the AMPA receptor potentiator LY 451646, mimic the effects of antidepressants in preclinical tests with high predictive validity. In humans, a single intravenous dose of ketamine produces an antidepressant effect that is rapid, robust and persistent. In this study, we examined the role of BDNF in expression of the antidepressant-like effects of ketamine and an AMPA receptor potentiator (LY 451646) in the forced swim test (FST). Ketamine and LY 451646 produced antidepressant-like effects in the FST in mice at 45 min after a single injection, but no effects were observed one week after a single ketamine injection. As previously reported, the effects of imipramine in the forced swim test were blunted in heterozygous BDNF knockout (bdnf(+/-)) mice. However ketamine and LY 451646 produced similar antidepressant-like responses in wildtype and bdnf(+/-) mice. Neither ketamine nor LY 451646 significantly influenced the levels BDNF or TrkB phosphorylation in the hippocampus when assessed at 45 min or 7 days after the drug administration. These data demonstrate that under the conditions tested, neither ketamine nor the AMPA-potentiator LY 451656 activate BDNF signaling, but produce a characteristic antidepressant-like response in heterozygous bdnf(+/-) mice. These data indicate that unlike biogenic amine-based agents, BDNF signaling does not play a pivotal role in the antidepressant effects of glutamate-based compounds.

However, the phenotypic manifestation of stress effects varies across individuals, likely due, in part, to genetic variation. Modeling the behavioral and neural consequences of stress across genetically diverse inbred mouse strains is a valuable approach to studying gene x stress interactions. Recent work has shown that C57BL/6J mice exposed to ten daily sessions of restraint stress exhibited increased exploration of the aversive light compartment in the light/dark exploration (LDE) test. Here we sought to clarify the nature of this stress-induced phenotype by testing the ability of treatment with various clinically efficacious drugs of different therapeutic classes to rescue it. Ten days of restraint increased light compartment exploration, reduced body weight and sensitized the corticosterone response to swim stress. Subchronic administration (during stress and LDE testing) of fluoxetine, and to a lesser extent, lithium chloride, rescued stress-induced LDE behavior. Chronic fluoxetine treatment prior to (plus during stress and testing) failed to block the LDE stress effect Acute administration of antipsychotic haloperidol, anti-ADHD medication methylphenidate or anxiolytic drug chlordiazepoxide, prior to LDE testing, was also unable to normalize the LDE stress effect. Collectively, these data demonstrate a treatment-selective prophylactic rescue of a restraint stress-induced behavioral abnormality in the C57BL/6J inbred strain. Further work with this novel model could help elucidate genetic and neural mechanisms mediating stress-induced changes in mouse 'emotion-relevant' behaviors and, ultimately, further understanding of the pathophysiology of stress-related neuropsychiatric disorders.

Furthermore, large variations in resolution and geometric distortion may exist among the fingerprint images acquired from different types of sensors. This distortion greatly challenges the traditional minutiae-based fingerprint matching algorithms. In this paper, we propose a novel ant colony optimization algorithm to establish minutiae correspondences in large-distorted fingerprints. First, minutiae similarity is measured by local features, and an assignment graph is constructed by local search. Then, the minutiae correspondences are established by a pseudo-greedy rule and local propagation, and the pheromone matrix is updated by the local and global update rules. Finally, the minutiae correspondences that maximize the matching score are selected as the matching result. To compensate resolution difference of fingerprint images captured from disparate sensors, a common resolution method is adopted. The proposed method is tested on FVC2004 DB1 and a FINGERPASS cross-matching database established by our lab. The experimental results demonstrate that the proposed algorithm can effectively improve the performance of large-distorted fingerprint matching, especially for those fingerprint images acquired from different modes of acquisition.

Out-of-band monitoring, i.e., deploying dedicated monitors and transmitting monitoring traffic using a separate channel, does not require instrumenting sensor nodes, and hence is flexible (can be added on top of any application) and energy conserving (not consuming resources of the sensor nodes). In this paper, we study fault-tolerant out-of-band monitoring for wireless sensor networks. Our goal is to place a minimum number of monitors in a sensor network so that all sensor nodes are monitored by k distinct monitors, and each monitor serves no more than w sensor nodes. We prove that this problem is NP-hard. For small-scale network, we formulate the problem as an Integer Linear Programming (ILP) problem, and obtain the optimal solution. For large-scale network, the ILP is not applicable, and we propose two algorithms to solve it. The first one is a In(kn) approximation algorithm, where n is the number of sensor nodes. The second is a simple heuristic scheme that has much shorter running time. We evaluate our algorithms using extensive simulation. In small-scale networks, the latter two algorithms provide results close to the optimal solution from the ILP for relatively dense networks. In large-scale networks, the performance of these two algorithms are similar, and for relatively dense networks, the number of monitors required by both algorithms is close to a lower bound.

Due to the predominantly advanced stage at the time of diagnosis treatment of cholangiocarcinoma is difficult. Apart from surgical resection, interventional treatment strategies are increasingly used in advanced stage tumours. The aim of the study was a retrospective comparison of the effect of the various forms of treatment on morbidity and mortality. Method. A total of 195 patients, received either chemotherapy or a combination of photodynamic therapy (PDT) or transarterial chemoembolization (TACE) and chemotherapy. Results. The median survival rate for all patients was 15.6 months, 50.8% were still alive 1 year after diagnosis. Patients, who had previously undergone surgery, survived 17.1 months longer than those without surgical treatment (P < .01). Chemotherapy prolonged the survival by 9.2 months (P = .47). Palliative patients under combination of chemotherapy and PDT survived on average 1.8 months longer (P = .28), with chemotherapy and TACE 9.8 months longer (P = .04) compared to chemotherapy alone. Conclusions. It appears that surgical treatment and chemotherapy combined with PDT or TACE may prolong survival.

The criteria and procedures for formal certification of global disease freedom are based on the biological and epidemiological features of the pathogen and its manifestations. Certification activities by previously endemic and at-risk countries include comprehensive documentation focusing on surveillance, reports of national independent review groups, and special field surveys. National and regional results are reviewed by authoritative International Commissions (ICs) which verify the findings by field visits. The ICs present their results to an independent WHO-convened group ("Global Commission" for smallpox), members of which participate in field visits. When fully satisfied, the Global Commission makes conclusions and recommendations to the World Health Assembly (WHA). Smallpox was confirmed eradicated in 1980 by the WHA less than three years after the last naturally occurring case was detected. Dracunculiasis (guinea worm) freedom has been certified in 187 countries. Regional commissions have certified the Americas, Asia, and Europe polio-free: however, re-establishment of endemic foci in countries previously declared disease-free has created special challenges for completing this program. Post-eradication activities require attention to surveillance, maximum security of the microbial agent, and essential research to assure maintenance of disease freedom.

This has resulted from appreciation of the huge medical, social, and economic burden that malaria exacts from endemic populations. Recent breakthroughs in drug development (artemisinin-based combination treatments), preventive interventions (long-lasting, insecticide-treated bed nets), improved diagnosis (rapid diagnostic tests), and community mobilization have resulted in deployment of new antimalarial tools. National programs supported by the Global Fund to Fight AIDS, Tuberculosis and Malaria, the U.S. President's Malaria Initiative, and other donors have resulted in substantial reductions in malaria morbidity and mortality. Bill and Melinda Gates have given great impetus to eradication with support for the development of key research strategies and direct funding of innovative research projects, including malaria vaccine and drug discovery, that could decrease disease and transmission. Linking research to field operations is a strategy that succeeded for smallpox eradication and will be required for the demise of malaria. Published by Elsevier Ltd.

Lessons learned from the campaign during the 1960s and 1970s in the Democratic Republic of Congo (DRC) can provide important information for the development of other eradication programs including polio. The DRC is the third largest country in Africa; the population suffers from extreme poverty, deteriorating infrastructure and health systems, and long periods of civil strife. Despite these challenges, DRC's smallpox eradication campaign was successful, eradicating smallpox only 41 months after initiation. DRC had been polio free since 2001; however, in 2006, imported cases were identified in the country. Polio transmission has since been re-established and DRC now has the second greatest number of reported polio cases in the world. Challenges which existed during the smallpox campaign in DRC are still present today; additionally, the polio vaccine itself poses unique challenges which include requiring multiple doses to confer immunity. In the fight against polio in DRC, it will be important to draw from the smallpox eradication experience. A number of important themes emerged during the campaign that could be beneficial to eradicating polio and future eradication programs that may follow. During the smallpox campaign, a standard vaccination program was implemented, surveillance was intensified, and there were strong collaborative programs with community involvement. These successful elements of the smallpox campaign should be adapted and applied in DRC in polio eradication programs. (C) 2011 Elsevier Ltd. All rights reserved.

As a result, it is necessary to develop tools that can identify sets of interacting genes that discriminate phenotypes without requiring that the classification boundary between phenotypes be convex. Results: We describe an extension and application of a new unsupervised statistical learning technique, known as the Partition Decoupling Method (PDM), to gene expression microarray data. This method may be used to classify samples based on multi-gene expression patterns and to identify pathways associated with phenotype, without relying upon the differential expression of individual genes. The PDM uses iterated spectral clustering and scrubbing steps, revealing at each iteration progressively finer structure in the geometry of the data. Because spectral clustering has the ability to discern clusters that are not linearly separable, it is able to articulate relationships between samples that would be missed by distance-and tree-based classifiers. After projecting the data onto the cluster centroids and computing the residuals ("scrubbing"), one can repeat the spectral clustering, revealing clusters that were not discernible in the first layer. These iterations, each of which provide a partition of the data that is decoupled from the others, are carried forward until the structure in the residuals is indistinguishable from noise, preventing over-fitting. We describe the PDM in detail and apply it to three publicly available cancer gene expression data sets. By applying the PDM on a pathway-by-pathway basis and identifying those pathways that permit unsupervised clustering of samples that match known sample characteristics, we show how the PDM may be used to find sets of mechanistically-related genes that may play a role in disease. An R package to carry out the PDM is available for download. Conclusions: We show that the PDM is a useful tool for the analysis of gene expression data from complex diseases, where phenotypes are not linearly separable and multi-gene effects are likely to play a role. Our results demonstrate that the PDM is able to distinguish cell types and treatments with higher accuracy than is obtained through other approaches, and that the Pathway-PDM application is a valuable technique for identifying disease-associated pathways.

Failure of expression of Transition protein 2 (TP2) and Protamine 2 (Prm2) proteins (chromatin remodelers, essential for spermatid elongation and completion of spermatogenesis) with preservation of their mRNA expression was observed in GRTH-null mice (azoospermic due to failure of spermatids to elongate). These were identified as target genes for the testis-specific miR-469, which is increased in the GRTH-null mice. Further analysis demonstrated that miR-469 repressed TP2 and Prm2 protein expression at the translation level with minor effect on mRNA degradation, through binding to the coding regions of TP2 and Prm2 mRNAs. The corresponding primary-microRNAs and the expression levels of Drosha and DGCR8 (both mRNA and protein) were increased significantly in the GRTH-null mice. miR-469 silencing of TP2 and Prm2 mRNA in pachytene spermatocytes and round spermatids is essential for their timely translation at later times of spermiogenesis, which is critical to attain mature sperm. Collectively, these studies indicate that GRTH, a multifunctional RNA helicase, acts as a negative regulator of miRNA-469 biogenesis and consequently their function during spermatogenesis.

Here we report a novel interaction between OGG1 and Poly( ADP-ribose) polymerase 1 (PARP-1), a DNA-damage sensor protein involved in DNA repair and many other cellular processes. We found that OGG1 binds directly to PARP-1 through the N-terminal region of OGG1, and this interaction is enhanced by oxidative stress. Furthermore, OGG1 binds to PARP-1 through its BRCA1 C-terminal (BRCT) domain. OGG1 stimulated the poly(ADP-ribosyl)ation activity of PARP-1, whereas decreased poly(ADP-ribose) levels were observed in OGG1(-/-) cells compared with wild-type cells in response to DNA damage. Importantly, activated PARP-1 inhibits OGG1. Although the OGG1 polymorphic variant proteins R229Q and S326C bind to PARP-1, these proteins were defective in activating PARP-1. Furthermore, OGG1(-/-) cells were more sensitive to PARP inhibitors alone or in combination with a DNA-damaging agent. These findings indicate that OGG1 binding to PARP-1 plays a functional role in the repair of oxidative DNA damage.

Our bioinformatic analysis revealed that there are possibly five isoforms of human GDNF gene with different pre- and pro-regions by inter- and intra-exon splicing. By using TaqMan primer probe sets, designed between exons, we verified the expression of all isoforms. Furthermore, a novel GDNFOS gene was found to be transcribed from the opposite strand of GDNF gene. GDNFOS gene has four exons that are spliced into different isoforms. GDNFOS1 and GDNFOS2 are long noncoding RNAs, and GDNFOS3 encodes a protein of 105 amino acids. To study human GDNF and GDNFOS regulation in neurodegenerative diseases, the protein and mRNA levels were measured by Western blot and RT-quantitative PCR, respectively, in postmortem middle temporal gyrus (MTG) of Alzheimer disease (AD) and Huntington disease (HD) patients in comparison with those of normal controls. In the MTG of AD patients, the mature GDNF peptide was down-regulated; however, the transcript of GDNF isoform from human exon 2 was up-regulated, whereas that of the conserved isoform from exon 1 remained unchanged in comparison with those of normal controls. In contrast, the mature GDNF peptide and the isoform mRNA levels were not changed in the MTG of HD. The findings of novel GDNF and GDNFOS isoforms and differences in tissue expression patterns dysregulated in AD brains may further reveal the role of endogenous GDNF in human brain diseases.

Fourteen adolescents with psychopathic traits and 14 healthy controls were assessed using fMRI while they categorized illegal and legal behaviors in a moral judgment implicit association task. fMRI data were then analyzed using random-effects analysis of variance and functional connectivity. Youths with psychopathic traits showed reduced amygdala activity when making judgments about legal actions and reduced functional connectivity between the amygdala and orbitofrontal cortex during task performance. These results suggest that psychopathic traits are associated with amygdala and orbitofrontal cortex dysfunction. This dysfunction may relate to previous findings of disrupted moral judgment in this population. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

This hierarchical ranking method is meant to reflect the idea that the goal of therapy is to prevent a clinical event and, failing that, to delay the occurrence of the event, hopefully for a substantial amount of time. We compare our approach with other methods including one method proposed by Feingold and Gillespie, a recommended procedure. The power is similar in many settings, but the hierarchical ranking can have substantially greater power under certain censoring patterns and also under a cure model, or models where treatment induces a substantial delay in some fraction of patients. We additionally feel that the hierarchical ranking method should be more clinically relevant in many settings. The method can also be applied to continuous outcomes censored by a limit of detection, such as HIV viremia. Copyright (C) 2011 John Wiley & Sons, Ltd.

TI Distinct PGE(2)-responder and non-responder phenotypes in human mast cell populations: "All or nothing" enhancement of antigen-dependent mediator release SO IMMUNOLOGY LETTERS LA English DT Article DE Mast cells; PGE(2); Degranulation; Cytokine release; Signaling ID FC-EPSILON-RI; PROSTAGLANDIN E-2; KIT ACTIVATION; RECEPTORS; PHOSPHORYLATION; DEGRANULATION; AGGREGATION; MECHANISMS; RESPONSES; 3-KINASE AB Reports indicate that prostaglandin (PG)E-2 markedly enhances antigen-mediated degranulation in mouse bone marrow-derived mast cells (BMMCs) but not in human mast cells (HuMCs). We have examined the underlying mechanism(s) for this disparity in HuMCs derived from the peripheral blood of multiple donors in addition to mouse BMMCs. HuMCs from half of these donors failed to respond to PGE(2) and the PGE(2) EP3 receptor agonist, sulprostone. However. HuMCs from the remaining donors and the LAD2 human MC line responded to PGE(2) and sulprostone with marked enhancement of antigen-mediated degranulation and IL-8 production in a similar manner to that observed in mouse BMMCs. The EP2 agonist, butaprost, failed to modulate antigen-mediated responses in any type of MCs. These distinct phenotypes could not be explained by differences in EP2 or EP3 expression nor by differences in the ability of PGE2 to elevate levels of cAMP, a signal recognized to down-regulate mast cell activation. Moreover, both responder and non-responder HuMC populations exhibited similar activation of phosphatidylinositol 3-kinase, and MAP kinases. However, translocation of PLC gamma(1) to the cell membrane and the associated calcium signal were enhanced only in the responder HuMC population indicating that the link between EP3 and PLC gamma is impaired in the non-responder HuMCs. Conclusions: These data provide a cautionary note for the translating of observations in the mouse to human mast cell-dependent disorders, but may also provide a basis for examining the effects of co-activating receptors in patients susceptible to allergic conditions.

It remains unclear whether CrP changes seen during malaria contribute to the development of anaemia, or result from an altered RBC age distribution due to suppressive effects of malaria on erythropoiesis. Methods: A cross sectional study was conducted in the north-east coast of Tanzania to investigate whether the changes in glycosylphosphatidylinositol (GPI)-anchored complement regulatory proteins (CD55 and CD59) contributes to malaria anaemia. Blood samples were collected from a cohort of children under intensive surveillance for Plasmodium falciparum parasitaemia and illness. Levels of CD55 and CD59 were measured by flow cytometer and compared between anaemic (8.08 g/dl) and non-anaemic children (11.42 g/dl). Results: Levels of CD55 and CD59 decreased with increased RBC age. CD55 levels were lower in anaemic children and the difference was seen in RBC of all ages. Levels of CD59 were lower in anaemic children, but these differences were not significant. CD55, but not CD59, levels correlated positively with the level of haemoglobin in anaemic children. Conclusion: The extent of CD55 loss from RBC of all ages early in the course of malarial anaemia and the correlation of CD55 with haemoglobin levels support the hypothesis that CD55 may play a causal role in this disorder.

There are regions of high and low recombination rates called hot and cold spots, respectively. The recombination rate parallels the frequency of DNA double-strand breaks (DSBs) that initiate meiotic recombination. The aim is to identify biological features associated with DSB frequency. We constructed vectors representing various chromatin and sequence-based features for 1179 DSB hot spots and 1028 DSB cold spots. Using a feature selection approach, we have identified five features that distinguish hot from cold spots in Saccharomyces cerevisiae with high accuracy, namely the histone marks H3K4me3, H3K14ac, H3K36me3, and H3K79me3; and GC content. Previous studies have associated H3K4me3, H3K36me3, and GC content with areas of mitotic recombination. H3K14ac and H3K79me3 are novel predictions and thus represent good candidates for further experimental study. We also show nucleosome occupancy maps produced using next generation sequencing exhibit a bias at DSB hot spots and this bias is strong enough to obscure biologically relevant information. A computational approach using feature selection can productively be used to identify promising biological associations. H3K14ac and H3K79me3 are novel predictions of chromatin marks associated with meiotic DSBs. Next generation sequencing can exhibit a bias that is strong enough to lead to incorrect conclusions. Care must be taken when interpreting high throughput sequencing data where systematic biases have been documented.

The human ortholog of this gene, MRDS1/OFCC1, is a potentially causal gene for orofacial cleft, as well as a susceptibility gene for schizophrenia, a devastating mental illness. Based on this evidence, we hypothesized that this gene could perform crucial functions in the development of head and brain structures in vertebrates. To test this hypothesis, we created Mrds1/Ofcc1-null mice. Mice were examined thoroughly using an abnormality screening system referred to as "the Japan Mouse Clinic". No malformations of the head structure, eye or other parts of the body were apparent in these knockout mice. However, the mutant mice showed a marked increase in serum c-glutamyl transpeptidase (GGT), a marker for liver damage, but no abnormalities in other liver-related measurements. We also performed a family-based association study on the gene in schizophrenia samples of Japanese origin. We found five single nucleotide polymorphisms (SNPs) located across the gene that showed significant transmission distortion, supporting a prior report of association in a Caucasian cohort. However, the knockout mice showed no behavioral phenotypes relevant to schizophrenia. In conclusion, disruption of the Mrds1/Ofcc1 gene elicits asymptomatic hyper-c-glutamyl-transpeptidasemia in mice. However, there were no phenotypes to support a role for the gene in the development of eye and craniofacial structures in vertebrates. These results prompt further examination of the gene, including its putative contribution to hyper-c-glutamyl transpeptidasemia and schizophrenia.

We conducted a randomized trial to determine whether a higher threshold for blood transfusion would improve recovery in patients who had undergone surgery for hip fracture. METHODS We enrolled 2016 patients who were 50 years of age or older, who had either a history of or risk factors for cardiovascular disease, and whose hemoglobin level was below 10 g per deciliter after hip-fracture surgery. We randomly assigned patients to a liberal transfusion strategy (a hemoglobin threshold of 10 g per deciliter) or a restrictive transfusion strategy (symptoms of anemia or at physician discretion for a hemoglobin level of <8 g per deciliter). The primary outcome was death or an inability to walk across a room without human assistance on 60-day follow-up. RESULTS A median of 2 units of red cells were transfused in the liberal-strategy group and none in the restrictive-strategy group. The rates of the primary outcome were 35.2% in the liberal-strategy group and 34.7% in the restrictive-strategy group (odds ratio in the liberal-strategy group, 1.01; 95% confidence interval [CI], 0.84 to 1.22), for an absolute risk difference of 0.5 percentage points (95% CI, -3.7 to 4.7). The rates of in-hospital acute coronary syndrome or death were 4.3% and 5.2%, respectively (absolute risk difference, -0.9%; 99% CI, -3.3 to 1.6), and rates of death on 60-day follow-up were 7.6% and 6.6%, respectively (absolute risk difference, 1.0%; 99% CI, -1.9 to 4.0). The rates of other complications were similar in the two groups. CONCLUSIONS A liberal transfusion strategy, as compared with a restrictive strategy, did not reduce rates of death or inability to walk independently on 60-day follow-up or reduce in-hospital morbidity in elderly patients at high cardiovascular risk.

Ubiquitination is one such modification with several E3 ubiquitin ligases implicated in TGF-beta signaling in marking crucial pathway components for proteasomal degradation. However, ubiquitination, particularly in the mono-or oligo-ubiquitin modifying form, is also known to regulate incorporation of substrate proteins into signaling complexes that involved in DNA repair, kinase activation, and endocytosis. This review focuses on recent advances in understanding the role of such non-degradative ubiquitination in TGF-beta signaling.

TI A Viral Vectored Prime-Boost Immunization Regime Targeting the Malaria Pfs25 Antigen Induces Transmission-Blocking Activity SO PLOS ONE LA English DT Article ID SUBUNIT VACCINE IMMUNOGENICITY; MEROZOITE SURFACE PROTEIN-1; PLASMODIUM-FALCIPARUM; FUNCTIONAL IMMUNOGENICITY; ADJUVANT VACCINES; SEXUAL STAGE; IN-VITRO; ANTIBODIES; CANDIDATE; IMMUNITY AB The ookinete surface protein Pfs25 is a macrogamete-to-ookinete/ookinete stage antigen of Plasmodium falciparum, capable of exerting high-level anti-malarial transmission-blocking activity following immunization with recombinant protein-in-adjuvant formulations. Here, this antigen was expressed in recombinant chimpanzee adenovirus 63 (ChAd63), human adenovirus serotype 5 (AdHu5) and modified vaccinia virus Ankara (MVA) viral vectored vaccines. Two immunizations were administered to mice in a heterologous prime-boost regime. Immunization of mice with AdHu5 Pfs25 at week 0 and MVA Pfs25 at week 10 (Ad-MVA Pfs25) resulted in high anti-Pfs25 IgG titers, consisting of predominantly isotypes IgG1 and IgG2a. A single priming immunization with ChAd63 Pfs25 was as effective as AdHu5 Pfs25 with respect to ELISA titers at 8 weeks post-immunization. Sera from Ad-MVA Pfs25 immunized mice inhibited the transmission of P. falciparum to the mosquito both ex vivo and in vivo. In a standard membrane-feeding assay using NF54 strain P. falciparum, oocyst intensity in Anopheles stephensi mosquitoes was significantly reduced in an IgG concentration-dependent manner when compared to control feeds (96% reduction of intensity, 78% reduction in prevalence at a 1 in 5 dilution of sera). In addition, an in vivo transmission-blocking effect was also demonstrated by direct feeding of immunized mice infected with Pfs25DR3, a chimeric P. berghei line expressing Pfs25 in place of endogenous Pbs25. In this assay the density of Pfs25DR3 oocysts was significantly reduced when mosquitoes were fed on vaccinated as compared to control mice (67% reduction of intensity, 28% reduction in prevalence) and specific IgG titer correlated with efficacy. These data confirm the utility of the adenovirus-MVA vaccine platform for the induction of antibodies with transmission-blocking activity, and support the continued development of this alternative approach to transmission-blocking malaria subunit vaccines.

TI The effect of systematic pediatric care on neonatal mortality and hospitalizations of infants born with oral clefts SO BMC PEDIATRICS LA English DT Article ID OROFACIAL CLEFTS; FOLLOW-UP; 1ST-YEAR MORTALITY; BIRTH-DEFECTS; OF-LIFE; LIP; PALATE; SURVIVAL; CHILDREN; ASSOCIATION AB Background: Cleft lip and/or palate (CL/P) increase mortality and morbidity risks for affected infants especially in less developed countries. This study aimed at assessing the effects of systematic pediatric care on neonatal mortality and hospitalizations of infants with cleft lip and/or palate (CL/P) in South America. Methods: The intervention group included live-born infants with isolated or associated CL/P in 47 hospitals between 2003 and 2005. The control group included live-born infants with CL/P between 2001 and 2002 in the same hospitals. The intervention group received systematic pediatric care between the 7th and 28th day of life. The primary outcomes were mortality between the 7th and 28th day of life and hospitalization days in this period among survivors adjusted for relevant baseline covariates. Results: There were no significant mortality differences between the intervention and control groups. However, surviving infants with associated CL/P in the intervention group had fewer hospitalization days by about six days compared to the associated control group. Conclusions: Early systematic pediatric care may significantly reduce neonatal hospitalizations of infants with CL/P and additional birth defects in South America. Given the large healthcare and financial burden of CL/P on affected families and the relatively low cost of systematic pediatric care, improving access to such care may be a cost-effective public policy intervention.

We have analyzed TP53 mutation patterns in tumors from this high-risk geographic area in search of clues to the mutagenic processes involved in causing ESCC. Methodology/Principal Findings: Biopsies of 119 confirmed ESCC tumor tissue from subjects enrolled in a case-control study conducted in Golestan Province were analyzed by direct sequencing of TP53 exons 2 through 11. Immunohistochemical staining for p53 was carried out using two monoclonal antibodies, DO7 and 1801. A total of 120 TP53 mutations were detected in 107/119 cases (89.9%), including 11 patients with double or triple mutations. The mutation pattern was heterogeneous with infrequent mutations at common TP53 "hotspots" but frequent transversions potentially attributable to environmental carcinogens forming bulky DNA adducts, including 40% at bases known as site of mutagenesis by polycyclic aromatic hydrocarbons (PAHs). Mutations showed different patterns according to the reported temperature of tea consumption, but no variation was observed in relation to ethnicity, tobacco or opium use, and alcoholic beverage consumption or urban versus rural residence. Conclusion/Significance: ESCC tumors in people from Golestan Province show the highest rate of TP53 mutations ever reported in any cancer anywhere. The heterogeneous mutation pattern is highly suggestive of a causative role for multiple environmental carcinogens, including PAHs. The temperature and composition of tea may also influence mutagenesis.

Methodology and Principal Findings: The present study included 4,004 ALS patients identified from the Swedish Patient Register during 1991-2007 and 20,020 age and sex matched general population controls. Conditional logistic regression was used to estimate the odds ratios (ORs) of ALS given a previous hospitalization for CNS infection or sepsis. Cox models were used to estimate the hazard ratios (HRs) of hospitalization for CNS infection or sepsis after ALS diagnosis. Overall, previous CNS infection (OR: 1.3, 95% confidence interval [CI]: 0.8, 2.4) or sepsis (OR: 1.2, 95% CI: 0.9, 1.6) was not associated with ALS risk. However, compared to ALS free individuals, ALS cases were more likely to be hospitalized for sepsis after diagnosis (HR: 2.6, 95% CI: 1.9, 3.5). We did not observe a higher risk of CNS infection after ALS diagnosis. Conclusions/Significance: Our results suggest that acute and severe infections unlikely contribute to the development of ALS; however, ALS patients are at a higher risk of sepsis after diagnosis, compared to ALS free individuals.

Myogenic Reorganization of MTOC, Golgi Complex and ER Exit Sites Persists Despite Lack of Normal Microtubule Tracks SO PLOS ONE LA English DT Article ID MUSCLE-CELL DIFFERENTIATION; HAMSTER OVARY CELLS; ENDOPLASMIC-RETICULUM; SKELETAL-MUSCLE; LIVING CELLS; CENTROSOME PROTEINS; ORGANIZING CENTERS; SIGNALING PATHWAY; BINDING-PROTEIN; MANNOSIDASE-II AB A wave of structural reorganization involving centrosomes, microtubules, Golgi complex and ER exit sites takes place early during skeletal muscle differentiation and completely remodels the secretory pathway. The mechanism of these changes and their functional implications are still poorly understood, in large part because all changes occur seemingly simultaneously. In an effort to uncouple the reorganizations, we have used taxol, nocodazole, and the specific GSK3-beta inhibitor DW12, to disrupt the dynamic microtubule network of differentiating cultures of the mouse skeletal muscle cell line C2. Despite strong effects on microtubules, cell shape and cell fusion, none of the treatments prevented early differentiation. Redistribution of centrosomal proteins, conditional on differentiation, was in fact increased by taxol and nocodazole and normal in DW12. Redistributions of Golgi complex and ER exit sites were incomplete but remained tightly linked under all circumstances, and conditional on centrosomal reorganization. We were therefore able to uncouple microtubule reorganization from the other events and to determine that centrosomal proteins lead the reorganization hierarchy. In addition, we have gained new insight into structural and functional aspects of the reorganization of microtubule nucleation during myogenesis. C1 [Zaal, Kristien J.

PALM/STORM rely on photoactivated proteins or photoswitching dyes, respectively, which makes them technically challenging. We present a simple and practical way of producing point localization-based superresolution images that does not require photoactivatable or photoswitching probes. Called bleaching/blinking assisted localization microscopy (BaLM), the technique relies on the intrinsic bleaching and blinking behaviors characteristic of all commonly used fluorescent probes. To detect single fluorophores, we simply acquire a stream of fluorescence images. Fluorophore bleach or blink-off events are detected by subtracting from each image of the series the subsequent image. Similarly, blink-on events are detected by subtracting from each frame the previous one. After image subtractions, fluorescence emission signals from single fluorophores are identified and the localizations are determined by fitting the fluorescence intensity distribution with a theoretical Gaussian. We also show that BaLM works with a spectrum of fluorescent molecules in the same sample. Thus, BaLM extends single molecule-based superresolution localization to samples labeled with multiple conventional fluorescent probes.

To assess the genomic landscapes of neoplastic cysts of the pancreas, we determined the exomic sequences of DNA from the neoplastic epithelium of eight surgically resected cysts of each of the major neoplastic cyst types: serous cystadenomas (SCAs), intraductal papillary mucinous neoplasms (IPMNs), mucinous cystic neoplasms (MCNs), and solid pseudopapillary neoplasms (SPNs). SPNs are low-grade malignancies, and IPMNs and MCNs, but not SCAs, have the capacity to progress to cancer. We found that SCAs, IPMNs, MCNs, and SPNs contained 10 +/- 4.6, 27 +/- 12, 16 +/- 7.6, and 2.9 +/- 2.1 somatic mutations per tumor, respectively. Among the mutations identified, E3 ubiquitin ligase components were of particular note. Four of the eight SCAs contained mutations of the von Hippel-Lindau gene (VHL), a key component of the VHL ubiquitin ligase complex that has previously been associated with renal cell carcinomas, SCAs, and other neoplasms. Six of the eight IPMNs and three of the eight MCNs harbored mutations of RNF43, a gene coding for a protein with intrinsic E3 ubiquitin ligase activity that has not previously been found to be genetically altered in any human cancer. The preponderance of inactivating mutations in RNF43 unequivocally establish it as a suppressor of both IPMNs and MCNs. SPNs contained remarkably few genetic alterations but always contained mutations of CTNNB1, previously demonstrated to inhibit degradation of the encoded protein (beta-catenin) by E3 ubiquitin ligases. These results highlight the essential role of ubiquitin ligases in these neoplasms and have important implications for the diagnosis and treatment of patients with cystic tumors.

These mutations often lead to misfolded proteins that are recognized by the unfolded protein response system and are degraded through the ubiquitin-proteasome pathway. Modulating this pathway with histone deacetylase inhibitors (HDACis) has been shown to improve protein stability in other disease settings. To identify the mechanisms involved in the regulation of GCase and determine the effects of HDACis on protein stability, we investigated the most prevalent mutations for nonneuronopathic (N370S) and neuronopathic (L444P) GD in cultured fibroblasts derived from GD patients and HeLa cells transfected with these mutations. The half-lives of mutant GCase proteins correspond to decreases in protein levels and enzymatic activity. GCase was found to bind to Hsp70, which directed the protein to TCP1 for proper folding, and to Hsp90, which directed the protein to the ubiquitin-proteasome pathway. Using a known HDACi (SAHA) and a unique small-molecule HDACi (LB-205), GCase levels increased rescuing enzymatic activity in mutant cells. The increase in the quantity of protein can be attributed to increases in protein half-life that correspond primarily with a decrease in degradation rather than an increase in chaperoned folding. HDACis reduce binding to Hsp90 and prevent subsequent ubiquitination and proteasomal degradation without affecting binding to Hsp70 or TCP1. These findings provide insight into the pathogenesis of GD and indicate a potent therapeutic potential of HDAC inhibitors for the treatment of GD and other human protein misfolding disorders.

Sirolimus (SRL) absorption and metabolism are affected by p-glycoprotein-mediated transport and CYP3A enzyme activity, which are further under the influences of cytokine concentrations. This retrospective study determined the associations of adenosine triphosphate-binding cassette, subfamily B, member 1 (ABCB1) 1236C>T, 2677 G>T/A, and 3435C>T, cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) -392A>G, cytochrome P450, family 3, subfamily A, polypeptide 5 (CYP3A5) 6986A>G and 14690G>A, interleukin (IL)-10 -1082G>A, and tumor necrosis factor (TNF) -308G>A polymorphisms with SRL dose-adjusted, weight-normalized trough concentrations (C/D) at 7 days, and at 1, 3, 6, and 12 months after initiation of SRL. Methods. Genotypes for 86 renal transplant patients who received SRL-based maintenance immunosuppressive therapy were determined using polymerase chain reaction followed by chip-based mass spectrometry. The changes of log-transformed C/D over the days posttransplantation were analyzed using a linear mixed-effects model, with adjustments for body mass index and weight-normalized doses of tacrolimus, prednisone, clotrimazole, and statins. Results. ABCB1 3435C>T and IL-10 -1082G>A were significantly associated with log C/D (P=0.0016 and 0.0394, respectively). Mean SRL C/D was 48% higher in patients with ABCB1 3435CT/TT genotype than those with 3435CC genotype, and was 24% higher in IL-10-1082GG compared with -1082AG/AA. Conclusions. ABCB1 3435C>T and IL-10 -1082G>A were significantly associated with long-term SRL dose requirements. Genetics can play a significant role in SRL dosing and may be useful in therapeutic monitoring of SRL in renal transplantation. Future replication studies are needed to confirm these associations.

However, gene signatures defined with different methods can be quite various even when applied the same disease and the same endpoint. Previous studies have shown that the correct selection of subsets of genes from microarray data is key for the accurate classification of disease phenotypes, and a number of methods have been proposed for the purpose. However, these methods refine the subsets by only considering each single feature, and they do not confirm the association between the genes identified in each gene signature and the phenotype of the disease. We proposed an innovative new method termed Minimize Feature's Size (MFS) based on multiple level similarity analyses and association between the genes and disease for breast cancer endpoints by comparing classifier models generated from the second phase of MicroArray Quality Control (MAQC-II), trying to develop effective meta-analysis strategies to transform the MAQC-II signatures into a robust and reliable set of biomarker for clinical applications. Results: We analyzed the similarity of the multiple gene signatures in an endpoint and between the two endpoints of breast cancer at probe and gene levels, the results indicate that disease-related genes can be preferably selected as the components of gene signature, and that the gene signatures for the two endpoints could be interchangeable. The minimized signatures were built at probe level by using MFS for each endpoint. By applying the approach, we generated a much smaller set of gene signature with the similar predictive power compared with those gene signatures from MAQC-II. Conclusions: Our results indicate that gene signatures of both large and small sizes could perform equally well in clinical applications. Besides, consistency and biological significances can be detected among different gene signatures, reflecting the studying endpoints. New classifiers built with MFS exhibit improved performance with both internal and external validation, suggesting that MFS method generally reduces redundancies for features within gene signatures and improves the performance of the model. Consequently, our strategy will be beneficial for the microarray-based clinical applications.

Deng, Youping Zhang, Chaoyang TI State Space Model with hidden variables for reconstruction of gene regulatory networks SO BMC SYSTEMS BIOLOGY LA English DT Article AB Background: State Space Model (SSM) is a relatively new approach to inferring gene regulatory networks. It requires less computational time than Dynamic Bayesian Networks (DBN). There are two types of variables in the linear SSM, observed variables and hidden variables. SSM uses an iterative method, namely Expectation-Maximization, to infer regulatory relationships from microarray datasets. The hidden variables cannot be directly observed from experiments. How to determine the number of hidden variables has a significant impact on the accuracy of network inference. In this study, we used SSM to infer Gene regulatory networks (GRNs) from synthetic time series datasets, investigated Bayesian Information Criterion (BIC) and Principle Component Analysis (PCA) approaches to determining the number of hidden variables in SSM, and evaluated the performance of SSM in comparison with DBN. Method: True GRNs and synthetic gene expression datasets were generated using GeneNetWeaver. Both DBN and linear SSM were used to infer GRNs from the synthetic datasets. The inferred networks were compared with the true networks. Results: Our results show that inference precision varied with the number of hidden variables. For some regulatory networks, the inference precision of DBN was higher but SSM performed better in other cases. Although the overall performance of the two approaches is compatible, SSM is much faster and capable of inferring much larger networks than DBN. Conclusion: This study provides useful information in handling the hidden variables and improving the inference precision.

However, this approach cannot reveal sufficient complexity to provide information on mechanisms that may regulate mRNA degradation, possibly on short timescales. To address this deficiency, we measured cell cycle-regulated decay in single yeast cells using single-molecule FISH. We found that two genes responsible for mitotic progression, SWI5 and CLB2, exhibit a mitosis-dependent mRNA stability switch. Their transcripts are stable until mitosis, when a precipitous decay eliminates the mRNA complement, preventing carryover into the next cycle. Remarkably, the specificity and timing of decay is entirely regulated by their promoter, independent of specific cis mRNA sequences. The mitotic exit network protein Dbf2p binds to SWI5 and CLB2 mRNAs cotranscriptionally and regulates their decay. This work reveals the promoter-dependent control of mRNA stability, a regulatory mechanism that could be employed by a variety of mRNAs and organisms.

Their synthesis takes mere seconds, leaving minimal time for recognition by the machinery for cotranslational protein translocation into the ER. The pathway taken by these substrates to enter the ER is not known. Here, we show that both in vivo and in vitro, small secretory proteins can enter the ER posttranslationally via a transient cytosolic intermediate. This intermediate contained calmodulin selectively bound to the signal peptides of small secretory proteins. Calmodulin maintained the translocation competence of small-protein precursors, precluded their aggregation and degradation, and minimized their inappropriate interactions with other cytosolic polypeptide-binding proteins. Acute inhibition of calmodulin specifically impaired small-protein translocation in vitro and in cells. These findings establish a mammalian posttranslational pathway for small-protein secretion and identify an unexpected role for calmodulin in chaperoning these precursors safely through the cytosol.

Here we report two new databases (MycoMass, MycoMap), 30 lipid fine maps, and mass spectrometry datasets that comprise a static lipidome. Further, by rapidly regenerating lipidomic datasets during biological processes, comparative lipidomics provides statistically valid, organism-wide comparisons that broadly assess lipid changes during infection or among clinical strains of mycobacteria. Using stringent data filters, we tracked more than 5,000 molecular features in parallel with few or no false-positive molecular discoveries. The low error rates allowed chemotaxonomic analyses of mycobacteria, which describe the extent of chemical change in each strain and identified particular strain-specific molecules for use as biomarkers.

Herein, we showed interleukin-12 acting via the transcription factor STAT4 induced both 1121 and BcI6 genes, generating cells with features of both Tfh and Th1 cells. However, STAT4 also induced the transcription factor T-bet. With ChIP-seq, we defined the genome-wide targets of T-bet and found that it repressed BcI6 and other markers of Tfh cells, thereby attenuating the nascent Tfh cell-like phenotype in the late phase of Th1 cell specification. Tfh-like cells were rapidly generated after Toxoplasma gondii infection in mice, but T-bet constrained Tfh cell expansion and consequent germinal center formation and antibody production. Our data argue that Tfh and Th1 cells share a transitional stage through the signal mediated by STAT4, which promotes both phenotypes. However, T-bet represses Tfh cell functionalities, promoting full Th1 cell differentiation.

We report that Th17 cells, despite displaying low expression of CD27 and other phenotypic markers of terminal differentiation, efficiently eradicated tumors and caused autoimmunity, were long lived, and maintained a core molecular signature resembling early memory CD8(+) cells with stem cell-like properties. In addition, we found that Th17 cells had high expression of Tcf7, a direct target of the Wnt and beta-catenin signaling axis, and accumulated beta-catenin, a feature observed in stem cells. In vivo, Th17 cells gave rise to Th1-like effector cell progeny and also self-renewed and persisted as IL-17A-secreting cells. Multipotency was required for Th17 cell-mediated tumor eradication because effector cells deficient in IFN-gamma or IL-17A had impaired activity. Thus, Th17 cells are not always short lived and are a less-differentiated subset capable of superior persistence and functionality.

Here, we showed that both IL-1 alpha and IL-1 beta are critically required for host resistance and identified two multifunctional inflammatory monocyte-macrophage and DC populations that coexpressed both IL-1 species at the single-cell level in lungs of Mtb-infected mice. Moreover, we demonstrated that interferons (IFNs) played important roles in regulating IL-1 production by these cells in vivo. Type I interferons inhibited IL-1 production by both subsets whereas CD4(+) T cell-derived IFN-gamma selectively suppressed monocyte-macrophages. These data provide a cellular basis for both the anti-inflammatory effects of IFNs and probacterial functions of type I IFNs during Mtb infection and reveal differential regulation of IL-1 production by distinct cell populations as an additional layer of complexity in the activity of IL-1 in vivo.

Zheng, Yixian TI Mouse B-Type Lamins Are Required for Proper Organogenesis But Not by Embryonic Stem Cells SO SCIENCE LA English DT Article ID NUCLEAR LAMINA; DIFFERENTIATION; ORGANIZATION; EXPRESSION; GENE; PROLIFERATION; PERIPHERY; DEFECTS AB B-type lamins, the major components of the nuclear lamina, are believed to be essential for cell proliferation and survival. We found that mouse embryonic stem cells (ESCs) do not need any lamins for self-renewal and pluripotency. Although genome-wide lamin-B binding profiles correlate with reduced gene expression, such binding is not directly required for gene silencing in ESCs or trophectoderm cells. However, B-type lamins are required for proper organogenesis. Defects in spindle orientation in neural progenitor cells and migration of neurons probably cause brain disorganizations found in lamin-B null mice. Thus, our studies not only disprove several prevailing views of lamin-Bs but also establish a foundation for redefining the function of the nuclear lamina in the context of tissue building and homeostasis.

Lipooligosaccharide (LOS) based conjugate vaccines derived from individual serotype M. catarrhalis only showed partial protection coverage. A vaccine combining LOS conjugates of two or three serotypes might provide a broader protection. Methods: Mice were immunized intranasally with the combined conjugates consisting of LOS from serotype A and B or serotype A, B, and C followed by challenge with different M. catarrhalis strains of three serotypes. Mouse lungs, nasal washes, and sera were collected after each challenge for bacterial counts, histological evaluation, cytokine profiles, antibody level and binding activity determinations. Results: Intranasal administration of the combined LOS conjugates not only enhanced pulmonary bacterial clearance of all three serotypes of M. catarrhalis strains in vaccinated mice, but also elevated serotype-specific anti-LOS immunoglobulin (Ig)A and IgG titers in nasal wash and serum respectively. Mice vaccinated with the combined LOS conjugates also showed increased interferon (IFN)-gamma, interleukin (IL)-12, and IL-4 in the lungs after challenges. Compared to the control group, mice immunized with the combined LOS conjugates also showed reduced lung inflammation after M. catarrhalis infections. The hyperimmune sera induced by the combined conjugates exhibited a broad cross-reactivity toward all three serotypes of M. catarrhalis under transmission electron microscopy. Conclusions: The combined vaccine of serotype A and B LOS conjugates provides protection against most M. catarrhalis strains by eliciting humoral and cellular immune responses.

The new ATIs 5, 8, and 10 inhibited tubulin polymerization, reduced cell growth of a panel of human transformed cell lines, and showed higher metabolic stability than the reference ester 3. These compounds induced mitotic arrest and apoptosis at a similar level as combretastatin A-4 and vinblastine and triggered caspase-3 expression in a significant fraction of cells in both p53-proficient and p53-defective cell lines. Importantly, ATIs 5, 8, and 10 were more effective than vinorelbine, vinblastine, and paclitaxel as growth inhibitors of the P-glycoprotein-overexpressing cell line NCI/ADR-RES. Compound 5 was shown to have medium metabolic stability in both human and mouse liver microsomes, in contrast to the rapidly degraded reference ester 3, and a pharmacokinetic profile in the mouse characterized by a low systemic clearance and excellent oral bioavailability.

TI mTORC1 and mTORC2 differentially regulate homeostasis of neoplastic and non-neoplastic human mast cells SO BLOOD LA English DT Article ID FC-EPSILON-RI; C-KIT; MEDIATOR RELEASE; COMPLEX 2; RICTOR; GROWTH; ACTIVATION; MASTOCYTOSIS; RAPTOR; PHOSPHORYLATION AB Increased mast cell burden is observed in the inflamed tissues and affected organs and tissues of patients with mast cell proliferative disorders. However, normal mast cells participate in host defense, so approaches to preferentially target clonally expanding mast cells are needed. We found that mammalian target of rapamycin complex 1(mTORC1) and 2(mTORC2) are up-regulated in neoplastic and developing immature mast cells compared with their terminally differentiated counter-parts. Elevated mTOR mRNA was also observed in bone marrow mononuclear cells of patients exhibiting mast-cell hyperplasia. Selective inhibition of mTORC1 and mTORC2 through genetic and pharmacologic manipulation revealed that, whereas mTORC1 may contribute to mast-cell survival, mTORC2 was only critical for homeostasis of neoplastic and dividing immature mast cells. The cytostatic effect of mTORC2 down-regulation in proliferating mast cells was deter-mined to be via inhibition of cell-cycle progression. Because mTORC2 was observed to play little role in the homeostasis of differentiated, nonproliferating, mature mast cells, these data provide a rationale for adopting a targeted approaching selectively inhibiting mTORC2 to effectively reduce the proliferation of mast cells associated with inflammation and disorders of mast cell proliferation while leaving normal differentiated mast cells largely unaffected.

Here we report the immunologic effects of 3 different IL-15 dosing strategies in Rhesus macaques. IL-15 at a dose of 20 mu g/kg/d administered by continuous intravenous infusion for 10 days resulted in a massive (100-fold) expansion of CD8(+) T-EM cells in the peripheral blood. In contrast, the administration of 20-40 mu g/kg/d of IL-15 by subcutaneous injection resulted in a more modest (10-fold) expansion of CD8(+) T-EM cells. NK expansion was similar in both the continuous intravenous and daily subcutaneous treatment groups. The observation that IL-15 administered by continuous intravenous infusion is able to induce markedly greater expansions of CD8(+) T-EM cells than the same dose administered by other routes may have important implications for clinical development of this cytokine.

Perturbations of the ribosome appear to be critically important in DBA; alterations in 9 different ribosomal protein genes have been identified in multiple unrelated families, along with rarer abnormalities of additional ribosomal proteins. However, at present, only 50% to 60% of patients have an identifiable genetic lesion by ribosomal protein gene sequencing. Using genome-wide single-nucleotide polymorphism array to evaluate for regions of recurrent copy variation, we identified deletions at known DBA-related ribosomal protein gene loci in 17% (9 of 51) of patients without an identifiable mutation, including RPS19, RPS17, RPS26, and RPL35A. No recurrent regions of copy variation at novel loci were identified. Because RPS17 is a duplicated gene with 4 copies in a diploid genome, we demonstrate haploinsufficient RPS17 expression and a small subunit ribosomal RNA processing abnormality in patients harboring RPS17 deletions. Finally, we report the novel identification of variable mosaic loss involving known DBA gene regions in 3 patients from 2 kindreds. These data suggest that ribosomal protein gene deletion is more common than previously suspected and should be considered a component of the initial genetic evaluation in cases of suspected DBA.

Here, we reasoned that a contribution of CNVs to mood disorders might be most evident for de novo mutations. We performed a genome-wide analysis of de novo CNVs in a cohort of 788 trios. Diagnoses of offspring included bipolar disorder (n = 185), schizophrenia (n = 177), and healthy controls (n = 426). Frequencies of de novo CNVs were significantly higher in bipolar disorder as compared with controls (OR = 4.8 [1.4,16.0], p = 0.009). De novo CNVs were particularly enriched among cases with an age at onset younger than 18 (OR = 6.3 [1.7,22.6], p = 0.006). We also confirmed a significant enrichment of de novo CNVs in schizophrenia (OR = 5.0 [1.5,16.8], p = 0.007). Our results suggest that rare spontaneous mutations are an important contributor to risk for bipolar disorder and other major neuropsychiatric diseases.

One reason for their ubiquity is their ability to escape herd immunity through rapid antigenic evolution and thereby to reinfect previously infected hosts. However, the ways in which these viruses evolve antigenically are highly diverse. Some have only limited diversity in the long-run, with every emergence of a new antigenic variant coupled with a replacement of the older variant. Other viruses rapidly accumulate antigenic diversity over time. Others still exhibit dynamics that can be considered evolutionary intermediates between these two extremes. Here, we present a theoretical framework that aims to understand these differences in evolutionary patterns by considering a virus's epidemiological dynamics in a given host population. Our framework, based on a dimensionless number, probabilistically anticipates patterns of viral antigenic diversification and thereby quantifies a virus's evolutionary potential. It is therefore similar in spirit to the basic reproduction number, the well-known dimensionless number which quantifies a pathogen's reproductive potential. We further outline how our theoretical framework can be applied to empirical viral systems, using influenza A/H3N2 as a case study. We end with predictions of our framework and work that remains to be done to further integrate viral evolutionary dynamics with disease ecology.

TI Novel Patient Cell-Based HTS Assay for Identification of Small Molecules for a Lysosomal Storage Disease SO PLOS ONE LA English DT Article ID THROUGHPUT SCREENING ASSAYS; METACHROMATIC LEUKODYSTROPHY; ARYLSULFATASE-A; PHARMACOLOGICAL CHAPERONES; BETA-HEXOSAMINIDASE; GAUCHER-DISEASE; ENZYME; INHIBITORS; FIBROBLASTS; DISORDERS AB Small molecules have been identified as potential therapeutic agents for lysosomal storage diseases (LSDs), inherited metabolic disorders caused by defects in proteins that result in lysosome dysfunctional. Some small molecules function assisting the folding of mutant misfolded lysosomal enzymes that are otherwise degraded in ER-associated degradation. The ultimate result is the enhancement of the residual enzymatic activity of the deficient enzyme. Most of the high throughput screening (HTS) assays developed to identify these molecules are single-target biochemical assays. Here we describe a cell-based assay using patient cell lines to identify small molecules that enhance the residual arylsulfatase A (ASA) activity found in patients with metachromatic leukodystrophy (MLD), a progressive neurodegenerative LSD. In order to generate sufficient cell lines for a large scale HTS, primary cultured fibroblasts from MLD patients were transformed using SV40 large T antigen. These SV40 transformed (SV40t) cells showed to conserve biochemical characteristics of the primary cells. Using a specific colorimetric substrate para-nitrocatechol sulfate (pNCS), detectable ASA residual activity were observed in primary and SV40t fibroblasts from a MLD patient (ASA-I179S) cultured in multi-well plates. A robust fluorescence ASA assay was developed in high-density 1,536-well plates using the traditional colorimetric pNCS substrate, whose product (pNC) acts as "plate fluorescence quencher" in white solid-bottom plates. The quantitative cell-based HTS assay for ASA generated strong statistical parameters when tested against a diverse small molecule collection. This cell-based assay approach can be used for several other LSDs and genetic disorders, especially those that rely on colorimetric substrates which traditionally present low sensitivity for assay-miniaturization. In addition, the quantitative cell-based HTS assay here developed using patient cells creates an opportunity to identify therapeutic small molecules in a disease-cellular environment where potentially disrupted pathways are exposed and available as targets.

Perhaps because hosts mount an active immune response against these compounds, the diversity of these compounds is large even among related blood sucking species. Because of these properties, saliva helps blood feeding as well as help the establishment of pathogens that can be transmitted during blood feeding. Methodology/Principal Findings: We have obtained 1,626,969 reads by pyrosequencing a salivary gland cDNA library from adult females Amblyomma maculatum ticks at different times of feeding. Assembly of this data produced 72,441 sequences larger than 149 nucleotides from which 15,914 coding sequences were extracted. Of these, 5,353 had>75% coverage to their best match in the non-redundant database from the National Center for Biotechnology information, allowing for the deposition of 4,850 sequences to GenBank. The annotated data sets are available as hyperlinked spreadsheets. Putative secreted proteins were classified in 133 families, most of which have no known function. Conclusions/Significance: This data set of proteins constitutes a mining platform for novel pharmacologically active proteins and for uncovering vaccine targets against A. maculatum and the diseases they carry.

Methodology/Principal Findings: Reactogenicity was recorded for 3 days following vaccination. Adverse events were monitored every 6 months for 3.5 years, during which pregnancy outcomes were recorded. Of the 16,402 volunteers, 69% of the participants reported an adverse event any time after the first dose. Only 32.9% experienced an AE within 30 days following any vaccination. Overall adverse event rates and attribution of relatedness did not differ between groups. The frequency of serious adverse events was similar in vaccine (14.3%) and placebo (14.9%) recipients (p = 0.33). None of the 160 deaths (85 in vaccine and 75 in placebo recipients, p = 0.43) was assessed as related to vaccine. The most common cause of death was trauma or traffic accident. Approximately 30% of female participants reported a pregnancy during the study. Abnormal pregnancy outcomes were experienced in 17.1% of vaccine and 14.6% (p = 0.13) of placebo recipients. When the conception occurred within 3 months (estimated) of a vaccination, the majority of these abnormal outcomes were spontaneous or elective abortions among 22.2% and 15.3% of vaccine and placebo pregnant recipients, respectively (p = 0.08). Local reactions occurred in 88.0% of vaccine and 61.0% of placebo recipients (p<0.001) and were more frequent after ALVAC-HIV than AIDSVAX B/E vaccination. Systemic reactions were more frequent in vaccine than placebo recipients (77.2% vs. 59.8%, p<0.001). Local and systemic reactions were mostly mild to moderate, resolving within 3 days. Conclusions/Significance: The ALVAC-HIV and AIDSVAX B/E vaccine regimen was found to be safe, well tolerated and suitable for potential large-scale use in Thailand.

The most widely used indicator of AD pathology in life at present is neuroimaging evidence of brain atrophy. We therefore performed a proteomic analysis of plasma to derive biomarkers associated with brain atrophy in AD. Using gel based proteomics we previously identified seven plasma proteins that were significantly associated with hippocampal volume in a combined cohort of subjects with AD (N = 27) and MCI (N = 17). In the current report, we validated this finding in a large independent cohort of AD (N = 79), MCI (N = 88) and control (N = 95) subjects using alternative complementary methods-quantitative immunoassays for protein concentrations and estimation of pathology by whole brain volume. We confirmed that plasma concentrations of five proteins, together with age and sex, explained more than 35% of variance in whole brain volume in AD patients. These proteins are complement components C3 and C3a, complement factor-I, gamma-fibrinogen and alpha-1-microglobulin. Our findings suggest that these plasma proteins are strong predictors of in vivo AD pathology. Moreover, these proteins are involved in complement activation and coagulation, providing further evidence for an intrinsic role of these pathways in AD pathogenesis.

TI Femtomole SHAPE Reveals Regulatory Structures in the Authentic XMRV RNA Genome SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID SELECTIVE 2'-HYDROXYL ACYLATION; IMMUNODEFICIENCY-VIRUS TYPE-1; SINGLE NUCLEOTIDE RESOLUTION; PRIMER EXTENSION SHAPE; MURINE LEUKEMIA-VIRUS; CAPILLARY-ELECTROPHORESIS; SECONDARY STRUCTURE; REVERSE TRANSCRIPTION; PRIMARY DETERMINANT; PCR PRIMERS AB Higher-order structure influences critical functions in nearly all noncoding and coding RNAs. Most single-nucleotide resolution RNA structure determination technologies cannot be used to analyze RNA from scarce biological samples, like viral genomes. To make quantitative RNA structure analysis applicable to a much wider array of RNA structure-function problems, we developed and applied high-sensitivity selective 2'-hydroxyl acylation analyzed by primer extension (SHAPE) to structural analysis of authentic genomic RNA of the xenotropic murine leukemia virus-related virus (XMRV). For analysis of fluorescently labeled cDNAs generated in high-sensitivity SHAPE experiments, we developed a two-color capillary electrophoresis approach with zeptomole molecular detection limits and subfemtomole sensitivity for complete SHAPE experiments involving hundreds of individual RNA structure measurements. High-sensitivity SHAPE data correlated closely (R = 0.89) with data obtained by conventional capillary electrophoresis. Using high-sensitivity SHAPE, we determined the dimeric structure of the XMRV packaging domain, examined dynamic interactions between the packaging domain RNA and viral nucleocapsid protein inside virion particles, and identified the packaging signal for this virus. Despite extensive sequence differences between XMRV and the intensively studied Moloney murine leukemia virus, architectures of the regulatory domains are similar and reveal common principles of gammaretrovirus RNA genome packaging.

TI Trans-, cis-, and dihydro-resveratrol: a comparative study SO CHEMISTRY CENTRAL JOURNAL LA English DT Article ID PROSTATE-CANCER CELLS; ESTROGEN-RECEPTOR; CYCLE ARREST; ER-BETA; GROWTH; ESTRADIOL; APOPTOSIS; ALCOHOL; ALPHA; WINE AB Background: Recent studies showed that moderate consumption of red or white wines increased the chances of breast cancer, while similar consumption of red wines, rich in trans-resveratrol (trans-R), decreased the rate of prostate cancer. This prompted us to explore the role of various forms of R in cancer proliferation. Results: Trans-R was found to be the most potent antiproliferative agent. Cis-R demonstrated somewhat less potency compared to trans-R. Unlike cis-R and trans-R, dihydro-R exhibits moderate proliferative effect on androgen-independent prostate cancer cell lines PC-3 and DU-145 at picomolar concentrations. At higher concentrations, dihydro-R caused proliferation inhibition, similar to cis-R and trans-R. The proliferative effect of dihydro-R at low concentrations can be reversed by trans-R which acts as a partial antagonist in the presence of dihydro-R. Mixtures of dihydro-R and trans-R demonstrated complex non-monotonic cross-modulation activity patterns. Conclusions: Dihydro-R exhibits proliferative effects in androgen-independent prostate cancer cells at picomolar and nanomolar concentrations. While the exact mechanism of these effects requires further evaluation, our preliminary results point to hormone receptor modulation activity. We also observed strong cross modulation between trans-R and dihydro-R at sub-picomolar concentrations. The role of dihydro-R in cancer proliferation related to moderate consumption of red wine remains an open question because dihydro-R has a very complex activity pattern in the presence of trans-R.

TI Characterization of a proximal Sp1 response element in the mouse Dlk2 gene promoter SO BMC MOLECULAR BIOLOGY LA English DT Article ID II CORE PROMOTER; HOMEOTIC PROTEIN DLK; DELTA-LIKE DLK; ADIPOCYTE DIFFERENTIATION; TATA-BOX; DNA METHYLATION; REPEAT MOTIFS; HUMAN GENOME; STEM-CELLS; EXPRESSION AB Background: DLK2 is an EGF-like membrane protein, closely related to DLK1, which is involved in adipogenesis. Both proteins interact with the NOTCH1 receptor and are able to modulate its activation. The expression of the gene Dlk2 is coordinated with that of Dlk1 in several tissues and cell lines. Unlike Dlk1, the mouse Dlk2 gene and its locus at chromosome 17 are not fully characterized. Results: The goal of this work was the characterization of Dlk2 mRNA, as well as the analysis of the mechanisms that control its basal transcription. First, we analyzed the Dlk2 transcripts expressed by several mouse cells lines and tissues, and mapped the transcription start site by 5' Rapid Amplification of cDNA Ends. In silico analysis revealed that Dlk2 possesses a TATA-less promoter containing minimal promoter elements associated with a CpG island, and sequences for Inr and DPE elements. Besides, it possesses six GC-boxes, considered as consensus sites for the transcription factor Sp1. Indeed, we report that Sp1 directly binds to the Dlk2 promoter, activates its transcription, and regulates its level of expression. Conclusions: Our results provide the first characterization of Dlk2 transcripts, map the location of the Dlk2 core promoter, and show the role of Sp1 as a key regulator of Dlk2 transcription, providing new insights into the molecular mechanisms that contribute to the expression of the Dlk2 gene.

TI Constructing a semantic predication gold standard from the biomedical literature SO BMC BIOINFORMATICS LA English DT Article ID INFORMATION EXTRACTION; CORPUS; TEXT; AGREEMENT; DOMAIN; GENE AB Background: Semantic relations increasingly underpin biomedical text mining and knowledge discovery applications. The success of such practical applications crucially depends on the quality of extracted relations, which can be assessed against a gold standard reference. Most such references in biomedical text mining focus on narrow subdomains and adopt different semantic representations, rendering them difficult to use for benchmarking independently developed relation extraction systems. In this article, we present a multi-phase gold standard annotation study, in which we annotated 500 sentences randomly selected from MEDLINE abstracts on a wide range of biomedical topics with 1371 semantic predications. The UMLS Metathesaurus served as the main source for conceptual information and the UMLS Semantic Network for relational information. We measured interannotator agreement and analyzed the annotations closely to identify some of the challenges in annotating biomedical text with relations based on an ontology or a terminology. Results: We obtain fair to moderate interannotator agreement in the practice phase (0.378-0.475). With improved guidelines and additional semantic equivalence criteria, the agreement increases by 12% (0.415 to 0.536) in the main annotation phase. In addition, we find that agreement increases to 0.688 when the agreement calculation is limited to those predications that are based only on the explicitly provided UMLS concepts and relations. Conclusions: While interannotator agreement in the practice phase confirms that conceptual annotation is a challenging task, the increasing agreement in the main annotation phase points out that an acceptable level of agreement can be achieved in multiple iterations, by setting stricter guidelines and establishing semantic equivalence criteria. Mapping text to ontological concepts emerges as the main challenge in conceptual annotation. Annotating predications involving biomolecular entities and processes is particularly challenging. While the resulting gold standard is mainly intended to serve as a test collection for our semantic interpreter, we believe that the lessons learned are applicable generally.

TI The King is Dead, Long Live the King: Entering A New Era of Stem Cell Research and Clinical Development SO JOURNAL OF TRANSLATIONAL MEDICINE LA English DT Editorial Material AB In mid November the biopharma industry was shocked by the announcement from Geron that they were ending work on embryonic stem cell research and therapy. For more than 10 years the public image of all stem cell research has been equated with embryonic stem cells. Unfortunately, a fundamentally important medical and financial fact was being ignored: embryonic stem cell therapy is extremely immature. In parallel to efforts in embryonic stem cell research and development, scientists and physicians in the field of adult stem cells realized that the natural role of adult stem cells in the body is to promote healing and to act like endogenous "repair cells" and, as a result, numerous companies have entered the field of adult stem cell therapy with the goal of expanding numbers of adult stem cells for administration to patients with various conditions. In contrast to embryonic stem cells, which are extremely expensive and potentially dangerous, adult cell cells are inexpensive and have an excellent safety record when used in humans. Many studies are now showing that adult stem cells are practical, patient-applicable, therapeutics that are very close to being available for incorporation into the practice of medicine. These events signal the entrance of the field of stem cells into a new era: an era where hype and misinformation no longer triumph over economic and medical realities.

TI A new world malaria map: Plasmodium falciparum endemicity in 2010 SO MALARIA JOURNAL LA English DT Article ID ENTOMOLOGICAL INOCULATION RATE; TRANSMISSION INTENSITY; DIAGNOSTIC-TECHNIQUES; SCHISTOSOMA-MANSONI; AFRICAN CHILDREN; ATLAS PROJECT; VIVAX MALARIA; PARASITE RATE; RISK; MODEL AB Background: Transmission intensity affects almost all aspects of malaria epidemiology and the impact of malaria on human populations. Maps of transmission intensity are necessary to identify populations at different levels of risk and to evaluate objectively options for disease control. To remain relevant operationally, such maps must be updated frequently. Following the first global effort to map Plasmodium falciparum malaria endemicity in 2007, this paper describes the generation of a new world map for the year 2010. This analysis is extended to provide the first global estimates of two other metrics of transmission intensity for P. falciparum that underpin contemporary questions in malaria control: the entomological inoculation rate (PfEIR) and the basic reproductive number (PfR). Methods: Annual parasite incidence data for 13,449 administrative units in 43 endemic countries were sourced to define the spatial limits of P. falciparum transmission in 2010 and 22,212 P. falciparum parasite rate (PfPR) surveys were used in a model-based geostatistical (MBG) prediction to create a continuous contemporary surface of malaria endemicity within these limits. A suite of transmission models were developed that link PfPR to PfEIR and PfR and these were fitted to field data. These models were combined with the PfPR map to create new global predictions of PfEIR and PfR. All output maps included measured uncertainty. Results: An estimated 1.13 and 1.44 billion people worldwide were at risk of unstable and stable P. falciparum malaria, respectively. The majority of the endemic world was predicted with a median PfEIR of less than one and a median PfR(c) of less than two. Values of either metric exceeding 10 were almost exclusive to Africa. The uncertainty described in both PfEIR and PfR was substantial in regions of intense transmission. Conclusions: The year 2010 has a particular significance as an evaluation milestone for malaria global health policy. The maps presented here contribute to a rational basis for control and elimination decisions and can serve as a baseline assessment as the global health community looks ahead to the next series of milestones targeted at 2015.

Because of the presence of the diacetylene groups, DC(8,9)PC undergoes polymerization upon UV (254 rim) exposure and assumes chromogenic properties. DC(8,9)PC photopolymerization in gel-phase matrix lipid 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) monitored by UV-vis absorption spectroscopy occurred within 2 min after UV treatment, whereas no spectral shifts were observed when DC(8,9)PC was incorporated into liquid-phase matrix 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC). Liquid chromatography-tandem mass spectrometry analysis showed a decrease in the amount of DC(8,9)PC monomer in both DPPC and POPC environments without any change in the matrix lipids in UV-treated samples. Molecular dynamics (MD) simulations of DPPC/DC(8,9)PC and POPC/DC(8,9)PC bilayers indicate that the DC(8,9)PC molecules adjust to the thickness of the matrix lipid bilayer. Furthermore, the motions of DC(8,9)PC in the gel-phase bilayer are more restricted than in the fluid bilayer. The restricted motional flexibility of DC(8,9)PC (in the gel phase) enables the reactive diacetylenes in individual molecules to align and undergo polymerization, whereas the unrestricted motions in the fluid bilayer restrict polymerization because of the lack of appropriate alignment of the DC(8,9)PC fatty acyl chains. Fluorescence microscopy data indicates the homogeneous distribution of lipid probe 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-lissamine rhodamine B sulfonyl ammonium salt (N-Rh-PE) in POPC/DC(8,9)PC monolayers but domain formation in DPPC/DC(8,9)PC monolayers. These results show that the DC(8,9)PC molecules cluster and assume the preferred conformation in the gel-phase matrix for the UV-triggered polymerization reaction.

We sought to identify common genetic variants associated with CAC and further investigate their associations with MI. Methods and Results-Computed tomography was used to assess quantity of CAC. A meta-analysis of genome-wide association studies for CAC was performed in 9961 men and women from 5 independent community-based cohorts, with replication in 3 additional independent cohorts (n=6032). We examined the top single-nucleotide polymorphisms (SNPs) associated with CAC quantity for association with MI in multiple large genome-wide association studies of MI. Genome-wide significant associations with CAC for SNPs on chromosome 9p21 near CDKN2A and CDKN2B (top SNP: rs1333049; P=7.58x10(-19)) and 6p24 (top SNP: rs9349379, within the PHACTR1 gene; P=2.65x10(-11)) replicated for CAC and for MI. Additionally, there is evidence for concordance of SNP associations with both CAC and MI at a number of other loci, including 3q22 (MRAS gene), 13q34 (COL4A1/COL4A2 genes), and 1p13 (SORT1 gene). Conclusions-SNPs in the 9p21 and PHACTR1 gene loci were strongly associated with CAC and MI, and there are suggestive associations with both CAC and MI of SNPs in additional loci. Multiple genetic loci are associated with development of both underlying coronary atherosclerosis and clinical events. (Circulation. 2011;124:2855-2864.)

TI Cholinergic Circuits Integrate Neighboring Visual Signals in a Drosophila Motion Detection Pathway SO CURRENT BIOLOGY LA English DT Article ID ELEMENTARY MOVEMENT DETECTORS; SYSTEM LIGHT MICROSCOPY; MUSCA-DOMESTICA; OPTIC LOBE; SENSITIVE PATHWAYS; WILD-TYPE; FLY; MELANOGASTER; ORGANIZATION; VISION AB Detecting motion is a feature of all advanced visual systems [1], nowhere more so than in flying animals, like insects [2, 3]. In flies, an influential autocorrelation model for motion detection, the elementary motion detector circuit (EMD; [4, 5]), compares visual signals from neighboring photoreceptors to derive information on motion direction and velocity. This information is fed by two types of interneuron, L1 and L2, in the first optic neuropile, or lamina, to downstream local motion detectors in columns of the second neuropile, the medulla. Despite receiving carefully matched photoreceptor inputs, L1 and L2 drive distinct, separable pathways responding preferentially to moving "on" and "off" edges, respectively [6, 7]. Our serial electron microscopy (EM) identifies two types of transmedulla (Tm) target neurons, Tm1 and Tm2, that receive apparently matched synaptic inputs from L2. Tm2 neurons also receive inputs from two retinotopically posterior neighboring columns via L4, a third type of lamina neuron. Light microscopy reveals that the connections in these L2/L4/Tm2 circuits are highly determinate. Single-cell transcript profiling suggests that nicotinic acetylcholine receptors mediate transmission within the L2/L4/Tm2 circuits, whereas L1 is apparently glutamatergic. We propose that Tm2 integrates signconserving inputs from neighboring columns to mediate the detection of front-to-back motion generated during forward motion.

In recent years, significant efforts have been made to dissect the molecular pathways involved in their carcinogenesis. Here we discuss the results of large-scale genomic analyses conducted to date and review the most active chemotherapies and targeted treatments. Methods We reviewed the literature for chemotherapeutic trials in the last 20 years and trials involving targeted therapies between 1999 and 2010. The search was supplemented by a review of abstracts presented at the annual meetings of the American Society of Clinical Oncology (from 1999 to 2010), at the first International Conference on Thymic Malignancies in 2009, and at a follow-up meeting of the newly formed International Thymic Malignancies Interest Group in 2010. Results Surgery remains the treatment of choice for operable tumors, whereas chemotherapy is standard in locally advanced and metastatic disease. Thus far, targeted therapies have been developed empirically. Histone deacetylase inhibitors have shown some activity in thymoma whereas sunitinib may be active in TC. There are no data to support the use of HER2- or EGFR-targeted therapies in thymic malignancies. Conclusion Drug development for the treatment of thymic malignancies is difficult because of the rarity of these tumors. Ethnic differences are becoming apparent, with aggressive subtypes being observed in Asians and African Americans. Incremental improvements in our understanding of tumor biology suggest that molecular profiling-directed therapies may be the preferred route of investigation in the future.

This exchange of ions produces a steady-state outwardly directed current, which is proportional in magnitude to the turnover rate. Under certain ionic conditions, a sudden voltage jump generates temporally distinct transient currents mediated by the Na+/K+ pump that represent the kinetics of extracellular Na+ binding/release and Na+ occlusion/deocclusion transitions. For many years, these events have escaped a proper thermodynamic treatment due to the relatively small electrical signal. Here, taking the advantages offered by the large diameter of the axons from the squid Dosidicus gigas, we have been able to separate the kinetic components of the transient currents in an extended temperature range and thus characterize the energetic landscape of the pump cycle and those transitions associated with the extracellular release of the first Na+ from the deeply occluded state. Occlusion/deocclusion transition involves large changes in enthalpy and entropy as the ion is exposed to the external milieu for release. Binding/unbinding is substantially less costly, yet larger than predicted for the energetic cost of an ion diffusing through a permeation pathway, which suggests that ion binding/unbinding must involve amino acid side-chain rearrangements at the site.

TI Discordant antigenic drift of neuraminidase and hemagglutinin in H1N1 and H3N2 influenza viruses SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID HONG-KONG INFLUENZA; A VIRUS; ANTIBODY; VACCINE; IMMUNITY; RESISTANCE; EVOLUTION; INFECTION; VARIANTS; SEQUENCE AB Seasonal epidemics caused by influenza virus are driven by antigenic changes (drift) in viral surface glycoproteins that allow evasion from preexisting humoral immunity. Antigenic drift is a feature of not only the hemagglutinin (HA), but also of neuraminidase (NA). We have evaluated the antigenic evolution of each protein in H1N1 and H3N2 viruses used in vaccine formulations during the last 15 y by analysis of HA and NA inhibition titers and antigenic cartography. As previously shown for HA, genetic changes in NA did not always lead to an antigenic change. The noncontinuous pattern of NA drift did not correspond closely with HA drift in either subtype. Although NA drift was demonstrated using ferret sera, we show that these changes also impact recognition by NA-inhibiting antibodies in human sera. Remarkably, a single point mutation in the NA of A/Brisbane/59/2007 was primarily responsible for the lack of inhibition by polyclonal antibodies specific for earlier strains. These data underscore the importance of NA inhibition testing to define antigenic drift when there are sequence changes in NA.

TI DNA double-strand breaks induced by high NaCl occur predominantly in gene deserts SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE hypertonicity; salt; DNA damage; kidney; mIMCD3 cells ID COMET ASSAY; DAMAGE RESPONSE; OSMOTIC-STRESS; CELLS; GAMMA-H2AX; REPAIR; CHECKPOINT; EVOLUTION; CHROMATIN; KINASE AB High concentration of NaCl increases DNA breaks both in cell culture and in vivo. The breaks remain elevated as long as NaCl concentration remains high and are rapidly repaired when the concentration is lowered. The exact nature of the breaks, and their location, has not been entirely clear, and it has not been evident how cells survive, replicate, and maintain genome integrity in environments like the renal inner medulla in which cells are constantly exposed to high NaCl concentration. Repair of the breaks after NaCl is reduced is accompanied by formation of foci containing phosphorylated H2AX (gamma H2AX), which occurs around DNA double-strand breaks and contributes to their repair. Here, we confirm by specific comet assay and pulsed-field electrophoresis that cells adapted to high NaCl have increased levels of double-strand breaks. Importantly,gamma H2AX foci that occur during repair of the breaks are nonrandomly distributed in the mouse genome. By chromatin immunoprecipitation using anti-gamma H2AX antibody, followed by massive parallel sequencing (ChIP-Seq), we find that during repair of double-strand breaks induced by high NaCl,gamma H2AX is predominantly localized to regions of the genome devoid of genes ("gene deserts"), indicating that the high NaCl-induced double-strand breaks are located there. Localization to gene deserts helps explain why the DNA breaks are less harmful than are the random breaks induced by genotoxic agents such as UV radiation, ionizing radiation, and oxidants. We propose that the universal presence of NaCl around animal cells has directly influenced the evolution of the structure of their genomes.

TI Fitness costs limit influenza A virus hemagglutinin glycosylation as an immune evasion strategy SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE antigenic drift; viral evolution ID A/PR/8/34 HEMAGGLUTININ; MONOCLONAL-ANTIBODIES; ANTIGENIC STRUCTURE; BALB/C MICE; CARBOHYDRATE; MOLECULE; NEUTRALIZATION; GLYCOPROTEIN; TRANSPORT; EPITOPE AB Here, we address the question of why the influenza A virus hemagglutinin (HA) does not escape immunity by hyperglycosylation. Uniquely among dozens of monoclonal antibodies specific for A/Puerto Rico/8/34, escape from H28-A2 neutralization requires substitutions introducing N-linked glycosylation at residue 131 or 144 in the globular domain. This escape decreases viral binding to cellular receptors, which must be compensated for by additional substitutions in HA or neuraminidase that enable viral replication. Sequence analysis of circulating H1 influenza viruses confirms the in vivo relevance of our findings: natural occurrence of glycosylation at residue 131 is always accompanied by a compensatory mutation known to increase HA receptor avidity. In vaccinated mice challenged with WT vs. H28-A2 escape mutants, the selective advantage conferred by glycan-mediated global reduction in antigenicity is trumped by the costs of diminished receptor avidity. These findings show that, although N-linked glycosylation can broadly diminish HA antigenicity, fitness costs restrict its deployment in immune evasion.

SHFV is a BSL-2 pathogen that has not been linked to human disease; as such, investigation of SHFV pathogenesis in non-human primates (NHPs) could serve as a model for hemorrhagic fever viruses such as Ebola, Marburg, and Lassa viruses. Here we describe the pathogenesis of SHFV in rhesus macaques inoculated with doses ranging from 50 PFU to 500,000 PFU. Disease severity was independent of dose with an overall mortality rate of 64% with signs of hemorrhagic fever and multiple organ system involvement Analyses comparing survivors and non-survivors were performed to identify factors associated with survival revealing differences in the kinetics of viremia, immunosuppression, and regulation of hemostasis. Notable similarities between the pathogenesis of SHFV in NHPs and hemorrhagic fever viruses in humans suggest that SHFV may serve as a suitable model of BSL-4 pathogens. Published by Elsevier Inc.

To investigate the role of this region in virus replication, we made alanine or leucine substitutions in each linker residue and two flanking residues. Three classes of mutants were identified: (i) S146A and T148A behave like wild type (WT); (ii) Y145A, 1150A, and L151A are noninfectious, assemble unstable cores with aberrant morphology, and synthesize almost no viral DNA; and (iii) P147L and S149A display a poorly infectious, attenuated phenotype. Infectivity of P147L and S149A is rescued specifically by pseudotyping with vesicular stomatitis virus envelope glycoprotein. Moreover, despite having unstable cores, these mutants assemble WT-like structures and synthesize viral DNA, although less efficiently than WT. Collectively, these findings demonstrate that the linker region is essential for proper assembly and stability of cores and efficient replication. Published by Elsevier Inc.

The complex salivary potion of hematophagous arthropods counteracts their host's hemostasis, inflammation, and immunity. Results: Transcriptome analysis revealed ubiquitous salivary protein families-such as the Antigen-5, Yellow, Kunitz domain, and serine proteases-in the S. guianense sialotranscriptome. Insect-specific families were also found. About 63.4% of all secreted products revealed protein families found only in Simulium. Additionally, we found a novel peptide similar to kunitoxin with a structure distantly related to serine protease inhibitors. This study revealed a relative increase of transcripts of the SVEP protein family when compared with Simulium vittatum and S. nigrimanum sialotranscriptomes. We were able to extract coding sequences from 164 proteins associated with blood and sugar feeding, the majority of which were confirmed by proteome analysis. Conclusions: Our results contribute to understanding the role of Simulium saliva in transmission of Onchocerca volvulus and evolution of salivary proteins in black flies. It also consists of a platform for mining novel anti-hemostatic compounds, vaccine candidates against filariasis, and immuno-epidemiologic markers of vector exposure.

TI Real-time PCR-based assay to quantify the relative amount of human and mouse tissue present in tumor xenografts SO BMC BIOTECHNOLOGY LA English DT Article ID IN-SITU HYBRIDIZATION; NUDE-MICE; DEVELOPMENTAL VALIDATION; MALIGNANT TRANSFORMATION; SPECIES IDENTIFICATION; HOST-CELLS; DNA; INDUCTION AB Background: Xenograft samples used to test anti-cancer drug efficacies and toxicities in vivo contain an unknown mix of mouse and human cells. Evaluation of drug activity can be confounded by samples containing large amounts of contaminating mouse tissue. We have developed a real-time quantitative polymerase chain reaction (qPCR) assay using TaqMan technology to quantify the amount of mouse tissue that is incorporated into human xenograft samples. Results: The forward and reverse primers bind to the same DNA sequence in the human and the mouse genome. Using a set of specially designed fluorescent probes provides species specificity. The linearity and sensitivity of the assay is evaluated using serial dilutions of single species and heterogeneous DNA mixtures. We examined many xenograft samples at various in vivo passages, finding a wide variety of human: mouse DNA ratios. This variation may be influenced by tumor type, number of serial passages in vivo, and even which part of the tumor was collected and used in the assay. Conclusions: This novel assay provides an accurate quantitative assessment of human and mouse content in xenograft tumors. This assay can be performed on aberrantly behaving human xenografts, samples used in bioinformatics studies, and periodically for tumor tissue frequently grown by serial passage in vivo.

These fixed-conformation nucleosides, methanocarba-deoxyadenosine or methanocarba-deoxycytidine in North (C3'-endo, N-MCdA and N-MCdC) or South (C2'-endo, S-MCdA and S-MCdC) conformations, were used to study inhibition of equilibrative (hENT14) and concentrative (hCNT13) nucleoside transport by individual recombinant hNTs produced in Saccharomyces cerevisiae cells or Xenopus laevis oocytes. Our results indicated that nucleosides in the North conformation were potent inhibitors of transport mediated by hCNTs whereas South nucleosides were inhibitors of hENTs, thus showing differences in the interaction with the hNTs. In summary, hCNTs exhibited strong preferences for North nucleosides whereas hENTs exhibited slight preferences for South nucleosides, demonstrating for the first time different conformational preferences among members of the two families of hNTs.

Although T-type calcium channels have been implicated in a number of disease states, including epilepsy, chronic pain, hypertension and cancer, the lack of selective inhibitors has slowed progress in understanding their precise roles. Kurtoxin is a potentially valuable tool with which to study T-type calcium channels. However, because of the limited availability of the native protein, little is known about the structure and molecular mechanism of kurtoxin. Here we report the expression of kurtoxin in Escherichia coli and the structural and functional characterization of the recombinant protein. The disulfide bond pairings and secondary structure of recombinant kurtoxin were characterized through enzymatic cleavage, mass analysis and CD spectroscopy. Recombinant kurtoxin almost completely inhibited the T-type calcium channel in a manner identical to the native toxin. The availability of recombinant kurtoxin that is identical to the native toxin should help in the study of T-type calcium channels and enable development of new strategies for producing even more-selective T-type calcium channel inhibitors and for investigating the molecular basis of the toxin-channel interactions.

TI Inactivation of prolyl hydroxylase domain (PHD) protein by epigallocatechin (EGCG) stabilizes hypoxia-inducible factor (HIF-1 alpha) and induces hepcidin (Hamp) in rat kidney SO BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS LA English DT Article DE EGCG; Hypoxia; PHD2; HIP-1 alpha a; Iron homeostasis; Hepcidin ID REGULATORY PEPTIDE HEPCIDIN; TEA POLYPHENOLS; IRON OVERLOAD; DEGRADATION; ERYTHROPOIESIS; INFLAMMATION; ANTIOXIDANT; PROTECTION; TRANSPORT; BINDING AB HIF-1 alpha plays a key role in iron uptake and transport in the liver, whose activity is tightly linked to the repression of hepcidin (Hamp). Hump prevents intestinal iron uptake and cellular efflux by negatively modulating ferroportin. Hump is also expressed in the kidneys, where transcriptional control by HIF-1 alpha remains poorly understood. We show that the administration of epigallocatechin gallate (EGCG) results in a considerable Hump expression in rat kidneys. We also provide evidence to show that EGCG inhibited prolyl hydroxylase (PHD) activity, essential for HIF-1 alpha degradation in vivo and in vitro. Rats that were dosed with EGCG (60 mg/kg, intraperitoneal) over a 7 day time course stabilized HIF-1 alpha protein in kidney tissues. Interestingly. Hump gene expression was induced, even after subjecting rats to a 4 h hypoxia treatment (8% oxygen). Using Hep3B cells, we determined that EGCG conferred its inhibitory action by complexing with PHD, altering its catalytic iron center and thus preventing HIF-1 alpha hydroxylation. These data demonstrate EGCG's therapeutic potential in modulating hepcidin expression in diseases associated with altered iron metabolism. Published by Elsevier Inc.

The assembly and permeability of this barrier are dependent on the zonula occludens (ZO) membrane-associated guanylate kinase (MAGUK) proteins ZO-1, -2, and -3. MAGUK proteins are characterized by a core motif of protein-binding domains that include a PDZ domain, a Src homology 3 (SH3) domain, and a region of homology to guanylate kinase (GUK); the structure of this core motif has never been determined for any MAGUK. To better understand how ZO proteins organize the assembly of protein complexes we have crystallized the entire PDZ3-SH3-GUK core motif of ZO-1. We have also crystallized this core motif in complex with the cytoplasmic tail of the ZO-1 PDZ3 ligand, junctional adhesion molecule A (JAM-A) to determine how the activity of different domains is coordinated. Our study shows a new feature for PDZ class II ligand binding that implicates the two highly conserved Phe(-2) and Ser(-3) residues of JAM. Our x-ray structures and NMR experiments also show for the first time a role for adjacent domains in the binding of ligands to PDZ domains in the MAGUK proteins family.

Methods: One Chinese LCA family was identified and an ophthalmologic examination was performed. The genetic defects were analyzed simultaneously by a genome-wide linkage scan with 382 polymorphic microsatellite markers, as well as by comprehensive mutational screening of 15 genes known to associate with LCA on the genomic DNA of this family. Results: Suggestive linkages were found in 13 chromosomal regions, of which only one harbored a known causative gene, crumbs homolog 1 (CRB1), on chromosome 1. Sanger sequencing of CRB1 identified two novel heterozygous mutations, c.3221T>C (p.L1074S) and c.2677-2A>C. In addition, a novel missense heterozygous mutation, c.938C>A (p.A313D), in spermatogenesis associated 7 (SPATA7), was detected in the proband after screening of the other 14 LCA causative genes. All three affected individuals of the family had compound heterozygous CRB1 mutations, and one of the three (the proband) had an additional mutation in SPATA7. The unaffected mother had the heterozygous c.3221T>C mutation in CRB1 and the heterozygous c.938C>A mutation in SPATA7. The unaffected father could not be tested, but presumably had the heterozygous c.2677-2A>C mutation in CRB1. The proband, with triallelic mutations in CRB1 and SPATA7, had a phenotype similar to other two affected brothers, suggesting the additional mutant allele in SPATA7 might not contribute to the disease. Similarly, the mother, with digenic mutations in CRB1 and SPATA7, had normal vision and fundi, suggesting the digenic mutations in these two genes might not cause disease. Conclusions: Digenic and triallelic mutations of CRB1 and SPATA7 were detected in a family with LCA. Our results imply that CRB1 and SPATA7 may not interact with each other directly. This emphasizes that care should be taken in invoking a mutation-disease association for digenic and triallelic mutations.

Although our understanding of polarization has progressed as a result of various scratch-wound and cell migration studies, variations in culture conditions required for such assays have prevented a unified understanding of the intricacies of MTOC and nucleus positioning that result in cell polarization. Here, we employ a new SMRT (for sparse, monolayer, round, triangular) analysis that uses a universal coordinate system based on cell centroid to examine the pathways regulating MTOC and nuclear positions in cells plated in a variety of conditions. We find that MTOC and nucleus positioning are crucially and independently affected by cell shape and confluence; MTOC off-centering correlates with the polarization of single cells; acto-myosin contractility and microtubule dynamics are required for single-cell polarization; and end binding protein 1 and light intermediate chain 1, but not Par3 and light intermediate chain 2, are required for single-cell polarization and directional cell motility. Using various cellular geometries and conditions, we implement a systematic and reproducible approach to identify regulators of MTOC and nucleus positioning that depend on extracellular guidance cues.

TI Thermodynamic analysis of the selectivity enhancement obtained by using smart hydrogels that are zwitterionic when detecting glucose with boronic acid moieties SO SENSORS AND ACTUATORS B-CHEMICAL LA English DT Article DE Glucose sensor; Smart hydrogel; Boronic acid; Monosaccharides; SANS ID DIRECT ELECTRICAL COMMUNICATION; PHYSIOLOGICAL SALT-SOLUTIONS; CHEMICALLY-MODIFIED ENZYMES; PHENYLBORONIC ACID; SWELLING PRESSURE; METAL-ELECTRODES; PHOTONIC CRYSTAL; RESPONSIVE GEL; IN-VIVO; SENSORS AB Because the botanic acid moiety reversibly binds to sugar molecules and has low cytotoxicity, boronic acid-containing hydrogels are being used in a variety of implantable glucose sensors under development, including sensors based on optical, fluorescence, and swelling pressure measurements. However, some method of glucose selectivity enhancement is often necessary, because isolated boronic acid molecules have a binding constant with glucose that is some 40 times smaller than their binding constant with fructose, the second most abundant sugar in the human body. In many cases, glucose selectivity enhancement is obtained by incorporating pendant tertiary amines into the hydrogel network, thereby giving rise to a hydrogel that is zwitterionic at physiological pH. However, the mechanism by which incorporation of tertiary amines confers selectivity enhancement is poorly understood. In order to clarify this mechanism, we use the osmotic deswelling technique to compare the thermodynamic interactions of glucose and fructose with a zwitterionic smart hydrogel containing boronic acid moieties. We also investigate the change in the structure of the hydrogel that occurs when it binds to glucose or to fructose using the technique of small angle neutron scattering. (C) 2011 Elsevier B.V.

TI Relation Among Body Mass Index, Exercise Training, and Outcomes in Chronic Systolic Heart Failure SO AMERICAN JOURNAL OF CARDIOLOGY LA English DT Article ID RANDOMIZED CONTROLLED-TRIAL; HF-ACTION; MORTALITY; OBESITY; STATEMENT AB Exercise training (ET) in patients with heart failure (HF), as demonstrated in the Heart Failure: A Controlled Trial Investigating Outcomes of Exercise TraiNing (HF-ACTION), was associated with improved exercise tolerance and health status and a trend toward reduced mortality or hospitalization. The present analysis of the HF-ACTION cohort examined the effect of ET in overweight and obese subjects compared to normal weight subjects with HF. Of 2,331 subjects with systolic HF randomized to aerobic ET versus usual care in the HF-ACTION, 2,314 were analyzed to determine the effect of ET on all-cause mortality, hospitalizations, exercise parameters, quality of life, and body weight changes by subgroups of body mass index (BMI). The strata included normal weight (BMI 18.5 to 24.9 kg/m(2)), overweight (BMI 25.0 to 29.9 kg/m(2)), obese I (BMI 30 to 34.9 kg/m(2)), obese II (BMI 35 to 39.9 kg/m(2)), and obese III (BMI >= 40 kg/m(2)). At enrollment, 19.4% of subjects were normal weight, 31.3% were overweight, and 49.4% were obese. A greater BMI was associated with a nonsignificant increase in all-cause mortality or hospitalization. ET was associated with nonsignificant reductions in all-cause mortality and hospitalization in each weight category (hazard ratio 0.98, 0.95, 0.92, 0.89, and 0.86 in the normal weight, overweight, obese I, obese II, and obese III categories, respectively; all p > 0.05). Modeled improvement in exercise capacity (peak oxygen consumption) and quality of life in the ET group was seen in all BMI categories. In conclusion, aerobic ET in subjects with HF was associated with a nonsignificant trend toward decreased mortality and hospitalization and a significant improvement in quality of life across the range of BMI categories.

TI Changes in Left Ventricular Diastolic Function of Asymptomatic Hereditary Hemochromatosis Subjects During Five Years of Follow-Up SO AMERICAN JOURNAL OF CARDIOLOGY LA English DT Article ID ATRIAL SYSTOLIC FUNCTION; CARDIOMYOPATHY; POPULATION; MANAGEMENT; STRESS AB We have previously reported that left ventricular (LV) diastolic function in those with cardiac asymptomatic hereditary hemochromatosis (HH) is similar to that of volunteer control (VC) subjects, despite a presence of augmented left atrial contractile function. However, concern still exists that those with HH might gradually develop LV diastolic dysfunction despite receiving conventional phlebotomy treatment. To address this concern, we prospectively monitored the LV diastolic function of those with HH and VCs during a 5-year period. A total of 14 subjects with newly diagnosed HH (age 51 +/- 12 years, 4 women, group A), 20 with chronic HH (age 51 +/- 9 years, 7 women, group B), and 18 VCs (age 50 +/- 8 years, 6 women, group C) successfully completed both the baseline evaluation of LV diastolic function, including tissue Doppler imaging, strain rate analysis with color-coded tissue Doppler, and the same studies repeated at 5 years of follow-up. All those with HH were New York Heart Association functional class I, were positive for the C282Y homozygote, and received conventional phlebotomy therapy. No VC had HH genetic mutations. The measures of LV diastolic function were comparable among the groups at 5 years of follow-up by analysis of variance. The echocardiographic measures of active left atrial contraction tended to decrease in the HH groups at 5 years of follow-up from baseline. In conclusion, LV diastolic function does not significantly deteriorate statistically during a 5-year period in subjects with cardiac asymptomatic HH after conventional phlebotomy treatment, regardless of their treatment history.

TI Invited Commentary: Natural Versus Unnatural Sex Ratios-A Quandary of Modern Times SO AMERICAN JOURNAL OF EPIDEMIOLOGY LA English DT Editorial Material DE abortion; sex ratio ID HUMANS; COHORT; CUBA AB The typical dilemma with sex-ratio findings is that when they are real, they aren't interesting, and when they are interesting, they aren't real. In this issue of the Journal, Fernandez et al. (Am J Epidemiol. 2011;174(12):1327-1331) describe a deviation of the sex ratio that is apparently both large and real. There was a temporary but distinct spike in the proportion of boys born in Cuba around the time of the collapse of the national economy during the 1990s. Although an excess of boys does not fit the prevailing biologic theory regarding maternal stress and the sex ratio, the data are consistent with results from the Dutch famine (where population-level deprivation was even more extreme). A new quandary arises in the modern era with interpretation of the sex ratio: If the decision to abort a pregnancy is influenced by the sex of the fetus, a change in the behavior of even a small proportion of women could influence the sex ratio at birth. The possible role of sex selection in the Cuban context is discussed. C1 [Wilcox, Allen J.; Baird, Donna D.] Natl Inst Environm Hlth Sci, Epidemiol Branch, NIH, Durham, NC 27709 USA.

However, recent outbreaks in the United States and Europe and the potential use of the bacteria for bioterrorism have focused interest on it. Furthermore, although anthrax was known to typically occur as one of three syndromes related to entry site of (i.e., cutaneous, gastrointestinal, or inhalational), a fourth syndrome including severe soft tissue infection in injectional drug users is emerging. Although shock has been described with cutaneous anthrax, it appears much more common with gastrointestinal, inhalational (5 of 11 patients in the 2001 outbreak in the United States), and injectional anthrax. Based in part on case series, the estimated mortalities of cutaneous, gastrointestinal, inhalational, and injectional anthrax are 1%, 25 to 60%, 46%, and 33%, respectively. Nonspecific early symptomatology makes initial identification of anthrax cases difficult. Clues to anthrax infection include history of exposure to herbivore animal products, heroin use, or clustering of patients with similar respiratory symptoms concerning for a bioterrorist event. Once anthrax is suspected, the diagnosis can usually be made with Gram stain and culture from blood or surgical specimens followed by confirmatory testing (e. g., PCR or immunohistochemistry). Although antibiotic therapy (largely quinolone-based) is the mainstay of anthrax treatment, the use of adjunctive therapies such as anthrax toxin antagonists is a consideration.

However, the precise mechanisms by which Salmonella induces cytoskeletal changes remain undefined. IQGAP1 (IQ motif-containing GTPase-activating protein 1) is a scaffold protein that binds multiple proteins including actin, the Rho GTPases Rac1 and Cdc42 (cell division cycle 42), and components of the MAPK (mitogen-activated protein kinase) pathway. We have shown previously that optimal invasion of Salmonella into HeLa cells requires IQGAP1. In the present paper, we use IQGAP1-null MEFs (mouse embryonic fibroblasts) and selected well-characterized IQGAP1 mutant constructs to dissect the molecular determinants of Salmonella invasion. Knockout of IQGAP1 expression reduced Salmonella invasion into MEFs by 75%. Reconstituting IQGAP1-null MEFs with wild-type IQGAP1 completely rescued invasion.

Our results indicate that, unlike G-CSF, AMD3100 substantially mobilizes both B and T lymphocytes into the peripheral blood. This led to significant increases in the peripheral blood content of both effector and regulatory T-cell populations, which translated into greater accumulation of these cells in the resulting leukapheresis products. Notably, CD4(+)/CD25(high)/CD127(low)/FoxP3(+) Tregs were efficiently mobilized with AMD3100-containing regimens, with as much as a 4.0-fold enrichment in the leukapheresis product compared with G-CSF alone. CD8(+) T cells were mobilized to a greater extent than CD4(+) T cells, with accumulation of 3.7 +/- 0.4-fold more total CD8+ T cells and 6.2 +/- 0.4-fold more CD8(+) effector memory T cells in the leukapheresis product compared with G-CSF alone. Given that effector memory T-cell sub-populations may mediate less GVHD compared with other effector T-cell populations and that Tregs are protective against GVHD, our results indicate that AMD3100 may mobilize a GVHD-protective T-cell repertoire, which would be of benefit in allogeneic hematopoietic stem cell transplantation.

Bladder-sparing approach incorporating chemoradiotherapy (CRT) improves QOL while not compromising survival outcomes in MIBC patients. In this approach, complete response to induction CRT is a prerequisite for bladder preservation and favorable oncological outcomes. We investigated a strategy to potentiate CRT response of bladder cancer cells by using Hsp90 inhibitors in preclinical models. Hsp90 inhibitors at low concentrations, which did not exert cytocidal effects but inactivated key anti-apoptotic proteins including erbB2, Akt and NF kappa B, efficiently sensitized bladder cancer cells (T24, 5637 and UM-UC-3 cells) to in vitro CRT by enhancing apoptosis. Importantly, the sensitizing effects were not observed in primarily cultured normal human urothelial cells. We also showed that CRT induces accumulation of nuclear phospho-Akt, which antagonizes apoptosis, and that Hsp90 inhibitors block the cellular process. Hsp90 inhibition sensitized bladder cancer cells to in vitro CRT more effectively than sole or combined inhibition of erbB2 and Akt. In mice UM-UC-3 tumor xenografts model, Hsp90 inhibitors successfully potentiated anti-tumor activity of CRT. These results encourage clinical trials of Hsp90 inhibitors to overcome CRT resistance in patients with MIBC.

Patients and Methods: Patients with advanced solid malignancies and no prior anti-VEGF exposure were enrolled. All patients had metastatic lesions amenable to FLT PET/CT imaging. Sunitinib was initiated at the standard dose of 50 mg p.o. daily either on a 4/2 or 2/1 schedule. FLT PET/CT scans were obtained at baseline, during sunitinib exposure, and after sunitinib withdrawal within cycle #1 of therapy. VEGF levels and sunitinib pharmacokinetic (PK) data were assessed at the same time points. Results: Sixteen patients (8 patients on 4/2 schedule and 8 patients on 2/1 schedule) completed all three planned FLT PET/CT scans and were evaluable for pharmacodynamic imaging evaluation. During sunitinib withdrawal (change from scans 2 to 3), median FLT PET standardized uptake value (SUV(mean)) increased +15% (range: -14% to 277%; P = 0.047) for the 4/2 schedule and +19% (range: -5.3% to 200%; P 0.047) for the 2/1 schedule. Sunitinib PK and VEGF ligand levels increased during sunitinib exposure and returned toward baseline during the treatment withdrawal. Conclusions: The increase of cellular proliferation during sunitinib withdrawal in patients with renal cell carcinoma and other solid malignancies is consistent with a VEGF receptor (VEGFR) tyrosine kinase inhibitor (TKI) withdrawal flare. Univariate and multivariate analysis suggest that plasma VEGF is associated with this flare, with an exploratory analysis implying that patients who experience less clinical benefit have a larger withdrawal flare. This might suggest that patients with a robust compensatory response to VEGFR TKI therapy experience early "angiogenic escape." Clin Cancer Res; 17(24); 7634-44. (C)2011 AACR.

TI BCL2 Predicts Survival in Germinal Center B-cell-like Diffuse Large B-cell Lymphoma Treated with CHOP-like Therapy and Rituximab SO CLINICAL CANCER RESEARCH LA English DT Article ID NON-HODGKINS-LYMPHOMA; R-CHOP; PROGNOSTIC-SIGNIFICANCE; PROTEIN EXPRESSION; ELDERLY-PATIENTS; IMMUNOHISTOCHEMICAL BIOMARKERS; BCL-2-ASSOCIATED RESISTANCE; CLINICAL-SIGNIFICANCE; MYC REARRANGEMENTS; MOLECULAR SUBTYPES AB Purpose: We have previously shown the prognostic significance of BCL2 expression in the activated B-cell-like diffuse large B-cell lymphoma (ABC-DLBCL) patients treated with cyclophosphamide-Adriamycin-vincristine- prednisone (CHOP) or CHOP-like therapy. However, after the inclusion of rituximab (R) in the CHOP regimen, several conflicting observations about the prognostic value of BCL2 expression have been reported. Experimental Design: We evaluated the R-CHOP cohort of 221 DLBCL cases with gene expression profiling data. BCL2 protein (n = 169), mRNA(n = 221) expression, and t(14; 18) (n = 144) were correlated with clinical outcome. The CHOP cohort (n = 181) was used for comparative analysis. Results: BCL2 protein expression has significant impact on overall survival (OS) and event-free survival (EFS) in DLBCL (OS, P = 0.009; EFS, P = 0.001) and GCB-DLBCL (OS, P = 0.03; EFS, P = 0.002) but not in ABC-DLBCL in the R-CHOP cohort. The survival differences for EFS in GCB-DLBCL were still observed in multivariate analysis. At the mRNA level, this correlation was observed in EFS in DLBCL (P = 0.006), but only a trend was observed in GCB-DLBCL (P = 0.09). The t(14; 18) was detected in 34% of GCB-DLBCL but was not associated with significant differences in survival. Gene enrichment analysis identified significant enrichment of the DLBCL "stromal-1" signatures and hypoxia-inducible factor 1 (HIF1-alpha) signature in BCL2 (-)GCB-DLBCL, whereas T(FH) cell signatures were enriched in BCL2(+) GCB-DLBCL. Conclusion: The prognostic significance of BCL2 has changed after inclusion of rituximab in the treatment protocol and is observed in the GCB-DLBCL rather than the ABC-DLBCL. Although rituximab has benefited patients in both DLBCL subgroups, the BCL2(+) GCB-DLBCL seems to receive less benefit from this treatment and may require other novel therapeutic intervention.

The impact of using older measurement technology has increased the measurement burden on both service providers and patients, while at the same time limiting the scope and frequency of measurement. The resulting burden can affect provider performance, patient access, and addiction recovery. This paper underscores the need for applying modern measurement theory techniques to reduce the measurement burden currently affecting most if not all major aspects of treatment and recovery. It is currently possible to obtain information more precisely, over a broad spectrum of recovery-oriented domains, faster and at lower cost than current measurement practices allow. However, a persistent research effort will be necessary to achieve that goal. C1 NIDA, NIH, Bethesda, MD 20892 USA.

Myocardial infarction may be complicated by perimyocarditis through unknown mechanisms. Our aim was to investigate the capacity of TLR2/TLR4 ligand biglycan to enhance the presentation of specific Ags released upon cardiomyocyte necrosis. In vitro, OVA-pulsed bone marrow-derived dendritic cells from wild-type (WT; C57BL/6) and TLR2-, TLR4-, MyD88-, or TRIF-deficient mice were cotreated with LPS, biglycan, or vehicle and incubated with OVA-recognizing MHC I- or MHC II-restricted T cells. Biglycan enhanced OVA-specific cross-priming by >80% to MHC I-restricted T cells in both TLR2- and TLR4-pathway-dependent manners. Accordingly, biglycan-induced cross-priming by both MyD88- and TRIF-deficient dendritic cells (DCs) was strongly diminished. OVA-specific activation of MHC II-restricted T cells was predominantly TLR4 dependent. Our first in vivo correlate was a model of experimental autoimmune perimyocarditis triggered by injection of cardiac Ag-pulsed DCs (BALB/c). Biglycan-treated DCs triggered perimyocarditis to a comparable extent and intensity as LPS-treated DCs (mean scores 1.3 +/- 0.3 and 1.5 +/- 0.4, respectively). Substitution with TLR4-deficient DCs abolished this effect. In a second in vivo approach, WT and biglycan-deficient mice were followed 2 wk after induction of myocardial infarction. WT mice demonstrated significantly greater myocardial T lymphocyte infiltration in comparison with biglycandeficient animals. We concluded that the TLR2/4 ligand biglycan, a component of the myocardial matrix, may enhance Ag-specific T cell priming, potentially via MyD88 and TRIF, and stimulate autoimmune perimyocarditis.

Phenotypically, they share some similarities with the small population of CD49b(-), CD27(+) immature splenic NK cells, as well as liver NK cells, but they differ in their expression of CD62L, TRAIL, and EOMES. Functionally, the peritoneal NK cells resemble the immature splenic NK cells in their production of IFN-gamma, GM-CSF, and TNF-alpha and in the killing of YAC-1 target cells. We also found that the peritoneum induces different behavior in mature and immature splenic NK cells. When transferred i.v. into RAG gamma c knockout mice, both populations undergo homeostatic proliferation in the spleen, but only the immature splenic NK cells are able to reach the peritoneum. When transferred directly into the peritoneum, the mature NK cells survive but do not divide, whereas the immature NK cells proliferate profusely. These data suggest that the peritoneum is not only home to a new subset of tissue-resident NK cells, but that it differentially regulates the migration and homeostatic proliferation of immature versus mature NK cells.

TI Structural Basis of Diverse Peptide Accommodation by the Rhesus Macaque MHC Class I Molecule Mamu-B*17: Insights into Immune Protection from Simian Immunodeficiency Virus SO JOURNAL OF IMMUNOLOGY LA English DT Article ID MAJOR HISTOCOMPATIBILITY COMPLEX; CYTOTOXIC T-LYMPHOCYTES; CELL-RECEPTOR RECOGNITION; LONG-TERM NONPROGRESSORS; CRYSTAL-STRUCTURES; PERIPHERAL-BLOOD; ESCAPE VARIANTS; VACCINE DESIGN; VIRAL PEPTIDES; SIV INFECTION AB The MHC class I molecule Mamu-B*17 has been associated with elite control of SIV infection in rhesus macaques, akin to the protective effects described for HLA-B*57 in HIV-infected individuals. In this study, we determined the crystal structures of Mamu-B*17 in complex with eight different peptides corresponding to immunodominant SIV(mac)239-derived CD8(+) T cell epitopes: HW8 (HLEVQGYW), GW10 (GSHLEVQGYW), MW9 (MHPAQTSQW), QW9 (QTSQWDDPW), FW9 (FQWMGYELW), MF8 (MRHVLEPF), IW9 (IRYPKTFGW), and IW11 (IRYPKTFGWLW). The structures reveal that not only P2, but also P1 and P3, can be used as N-terminal anchor residues by Mamu-B*17-restricted peptides. Moreover, the N-terminal anchor residues exhibit a broad chemical specificity, encompassing basic (H and R), bulky polar aliphatic (Q), and small (T) residues. In contrast, Mamu-B*17 exhibits a very narrow preference for aromatic residues (W and F) at the C terminus, similar to that displayed by HLA-B*57. Flexibility within the whole peptide-binding groove contributes to the accommodation of these diverse peptides, which adopt distinct conformations. Furthermore, the unusually large pocket D enables compensation from other peptide residues if P3 is occupied by an amino acid with a small side chain. In addition, residues located at likely TCR contact regions present highly flexible conformations, which may impact TCR repertoire profiles. These findings provide novel insights into the structural basis of diverse peptide accommodation by Mamu-B*17 and highlight unique atomic features that might contribute to the protective effect of this MHC I molecule in SIV-infected rhesus macaques.

TI Was the drop in mammography rates in 2005 associated with the drop in hormone therapy use? SO CANCER LA English DT Article DE mammography; hormone therapy; breast cancer; National Health Interview Surveys; women's health; primary care ID BREAST-CANCER INCIDENCE; HEALTH-CARE PROVIDERS; SCREENING MAMMOGRAPHY; UNITED-STATES; INCREASE RECOMMENDATION; COLORECTAL CANCERS; WOMEN; ACCURACY; PROGRAMS; BENEFITS AB BACKGROUND: In 2005, mammography rates in the United States dropped nationally for the first time among age-eligible women. An increased risk of breast cancer related to hormone therapy (HT) use reported in 2002 led to a dramatic drop in its use by 2005. Because current users of HT also tend to have higher mammography rates, the authors examined whether concurrent drops in HT and mammography use were associated. METHODS: Multivariate logistic regression was used to test for an interaction between HT use and survey year, controlling for a range of measurable factors in data from the 2000 and 2005 National Health Interview Surveys (NHIS). RESULTS: Women ages 50 to 64 years were more likely to report a recent mammogram if they also reported more education, a usual source of care, private health insurance, any race except non-Hispanic Asian, talking with an obstetrician/gynecologist or other physician in the past 12 months, or were currently taking HT. Women aged >= 65 years were more likely to report a recent mammogram if they also reported younger age (ages 65-74 years), more education, a usual source of care, having Medicare Part B or other supplemental Medicare insurance, excellent health, any race except non-Hispanic Asian, talking with an obstetrician/gynecologist or other physician in the past 12 months, or were currently taking HT. CONCLUSIONS: The change in HT use was associated with the drop in mammography use for women ages 50 to 64 years but not for women aged >= 65 years. NHIS data explained 70% to 80% of the change in mammography use. Cancer 2011; 117: 5450-60. (C) 2011 American Cancer Society.

METHODS: Eligible patients had CNS malignancies that required a (minimum) 2-week course of RT. Sunitinib (37.5 mg) was administered daily for the duration of RT with optional treatment extension of 1 month. Urine was collected at 3 time points for correlative bio-marker studies. The primary endpoint was acute toxicity defined according to Common Toxicity Criteria version 3. RESULTS: Fifteen patients were enrolled (12 with CNS metastasis and 3 with primary tumors). RT doses ranged from 14 Gray (Gy) to 70 Gy (1.8-3.5 Gy per fraction). Acute toxicities included hematologic, nausea, hyperglycemia, fatigue, hypocalcemia, and diarrhea. Six patients (40%) developed grade <= 2 toxicities. Grade 3 toxicities occurred in 7 patients (47%) and included hematologic toxicity, fatigue, deep vein thrombosis, dysphasia, hyperglycemia, and hyponatremia. No grade 3 through 5 hypertensive events or intracerebral hemorrhages occurred. Two grade 5 adverse events attributed to disease progression occurred. The median follow-up was 34.2 months. Two patients (13%) achieved a partial response, 9 patients (60%) had stable disease, and 2 patients (13%) patients had progressive disease. The 6-month progression-free survival rate for patients who had brain metastasis was 58%. Grade 3 hematologic toxicity was correlated with greater changes in vascular endothelial growth factor levels changes between baseline and the completion of RT. CONCLUSIONS: Continuous 37.5-mg sunitinib combined with RT in patients who had CNS malignancies yielded acceptable toxicities and adverse events. The current results indicated that changes in urine vascular endothelial growth factor levels are associated with hematologic toxicity, and this association should be analyzed in a larger cohort. The feasibility, safety, and early response results warrant a phase 2 trial. Cancer 2011; 117: 5548-59. (C) 2011 American Cancer Society.

In response to debate regarding catch-up vaccination of young adult women, this study examined whether 18- to 26-year-old women most likely to benefit from catch-up vaccination were aware of the HPV vaccine, and initiated the vaccine series by the end of 2008. METHODS: We used data from the 2008 National Health Interview Survey to assess HPV vaccine awareness and use, and reasons for not vaccinating, among women aged 18-26 years (n = 1583). Sociodemographic, health care access, and health history factors associated with vaccine initiation were assessed using multivariate logistic regression. RESULTS: Overall, 11.7% of women aged 18-26 years reported receiving at least 1 dose of the HPV vaccine by the end of 2008. In multivariate analyses, younger age, history of previous HPV infection, unmarried status, health insurance, flu shot in the past year, and receipt of 1 or more recommended lifetime vaccines were significantly associated with HPV vaccine initiation. Two-fifths (39.6%) of unvaccinated women were interested in receiving the HPV vaccine (n 1327). Primary reasons for lack of interest in the vaccine were belief that it was not needed, not knowing enough about it, concerns about safety, and not being sexually active. CONCLUSION: HPV vaccine coverage among young adult women was low, and lower among the uninsured than the insured. Public financing and care provision programs have the potential to expand vaccine coverage among uninsured women, who are at increased risk of cervical cancer. Cancer 2011; 117: 5560-8.

TI Hair dye use and risk of bladder cancer in the New England bladder cancer study SO INTERNATIONAL JOURNAL OF CANCER LA English DT Article DE hair dyes; bladder; cancer; aromatic amines; genetics ID PERSONAL USE; METAANALYSIS; N-ACETYLTRANSFERASE-2; SMOKING; SUSCEPTIBILITY; CARCINOGENESIS; IDENTIFICATION; POLYMORPHISM; NAT2 AB Aromatic amine components in hair dyes and polymorphisms in genes that encode enzymes responsible for hair dye metabolism may be related to bladder cancer risk. We evaluated the association between hair dye use and bladder cancer risk and effect modification by N-acetyltransferase-1 (NAT1), NAT2, glutathione S-transferase Mu-1 (GSTM1) and glutathione S-transferase theta-1 (GSTT1) genotypes in a population-based case-control study of 1193 incident cases and 1418 controls from Maine, Vermont and New Hampshire enrolled between 2001 and 2004. Individuals were interviewed in person using a computer-assisted personal interview to assess hair dye use and information on potential confounders and effect modifiers. No overall association between age at first use, year of first use, type of product, color, duration or number of applications of hair dyes and bladder cancer among women or men was apparent, but increased risks were observed in certain subgroups. Women who used permanent dyes and had a college degree, a marker of socioeconomic status, had an increased risk of bladder cancer [odds ratio (OR) = 3.3, 95% confidence interval (CI): 1.2-8.9]. Among these women, we found an increased risk of bladder cancer among exclusive users of permanent hair dyes who had NAT2 slow acetylation phenotype (OR = 7.3, 95% CI: 1.6-32.6) compared to never users of dye with NAT2 rapid/intermediate acetylation phenotype. Although we found no relation between hair dye use and bladder cancer risk in women overall, we detected evidence of associations and gene-environment interaction with permanent hair dye use; however, this was limited to educated women. These results need confirmation with larger numbers, requiring pooling data from multiple studies.

HR-HPV varies by anatomic site, and it is unknown whether MC decreases HR-HPV on the penile shaft. We assessed the efficacy of MC to reduce HR-HPV on the penile shaft and compared it to known efficacy of MC to reduce HR-HPV on the coronal sulcus. HIV-negative men randomized to receive immediate circumcision (intervention) or circumcision delayed for 24 months (control) were evaluated for HR-HPV at 12 months postenrollment using the Roche HPV Linear Array assay. Among swabs with detectable beta-globin or HPV, year 1 HR-HPV prevalence on the coronal sulcus was 21.5% in the intervention arm and 36.3% in the control arm men [ adjusted prevalence risk ratios (PRRs) = 0.57, 95% CI 0.39-0.84, p = 0.005]. On the shaft, year 1 HR-HPV prevalence was 15.5% in the intervention and 23.8% in the control arm (adjusted PRR = 0.66, 95% CI 0.39-1.12, p = 0.12). Efficacy of MC to reduce HR-HPV on the shaft was similar to efficacy on the coronal sulcus (p = 0.52). In a sensitivity analysis in which swabs without detectable b-globin or HPV were included as HPV negative, prevalence of HR-HPV on the shaft was lower in the intervention arm (7.8%) than control arm (13.6%; PRR 0.57, 95% CI 0.33-0.99, p < 0.05). HR-HPV was more frequently detected on the coronal sulcus than penile shaft among uncircumcised men (36.3% vs. 23.8%, respectively, p = 0.02) and circumcised men (21.5% vs. 15.5%, respectively, p = 0.24). MC reduced HR-HPV prevalence on both the coronal sulcus and shaft. C1 [Tobian, Aaron A. R.] Johns Hopkins Univ, Dept Pathol, Sch Med, Baltimore, MD 21287 USA. [Tobian, Aaron A.

TI Water-Exclusion and Liquid-Structure Forces in Implicit Solvation SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID SOLVENT-INDUCED FORCES; PROTEIN-PROTEIN INTERACTIONS; SCREENED COULOMB POTENTIALS; SIDE-CHAIN INTERACTIONS; CONTINUUM ELECTROSTATICS; AMINO-ACID; DIELECTRIC-PROPERTIES; MOLECULAR-MECHANICS; FOLDING SIMULATIONS; NEUTRON-SCATTERING AB A continuum model of solvation is proposed to describe (i) long-range electrostatic effects of water exclusion resulting from incomplete and anisotropic hydration in crowded environments and (ii) short-range effects of liquid-structure forces on the hydrogen-bond interactions at solute/water interfaces. The model is an extension of the phenomenological screened coulomb potential-based implicit model of solvation. The developments. reported here allow a more realistic representation of highly crowded and spatially heterogeneous environments, such as those in the interior of a living cell. Only the solvent is treated as a continuum medium. It is shown that the electrostatic effects of long-range water-exclusion can strongly affect protein protein binding energies and are then related to the thermodynamics of complex formation. Hydrogen-bond interactions modulated by the liquid structure at interfaces are calibrated based on systematic calculations of potentials of mean force in explicit water. The electrostatic component of the model is parametrized for, monovalent, divalent and trivalent ions. The conceptual and practical aspects of the model are discussed based on simulations of protein complexation and peptide folding. The current implementation is similar to 1.5 times slower than the gas-phase force field and exhibits good parallel performance.

TI Structure of HIV-1 gp120 V1/V2 domain with broadly neutralizing antibody PG9 SO NATURE LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; ENVELOPE GLYCOPROTEIN; POTENT NEUTRALIZATION; DEXTRAN SULFATE; T-CELLS; EPITOPE; SOFTWARE; RECEPTOR; BINDING; SYSTEM AB Variable regions 1 and 2 (V1/V2) of human immunodeficiency virus-1 (HIV-1) gp120 envelope glycoprotein are critical for viral evasion of antibody neutralization, and are themselves protected by extraordinary sequence diversity and N-linked glycosylation. Human antibodies such as PG9 nonetheless engage V1/V2 and neutralize 80% of HIV-1 isolates. Here we report the structure of V1/V2 in complex with PG9. V1/V2 forms a four-stranded beta-sheet domain, in which sequence diversity and glycosylation are largely segregated to strand-connecting loops. PG9 recognition involves electrostatic, sequence-independent and glycan interactions: the latter account for over half the interactive surface but are of sufficiently weak affinity to avoid autoreactivity. The structures of V1/V2-directed antibodies CH04 and PGT145 indicate that they share a common mode of glycan penetration by extended anionic loops. In addition to structurally defining V1/V2, the results thus identify a paradigm of antibody recognition for highly glycosylated antigens, which-with PG9-involves a site of vulnerability comprising just two glycans and a strand.

TI RAF inhibitor resistance is mediated by dimerization of aberrantly spliced BRAF(V600E) SO NATURE LA English DT Article ID BRAF; KINASE; HETERODIMERIZATION; MELANOMA; PATHWAY; CRAF; MEK AB Activated RAS promotes dimerization of members of the RAF kinase family(1-3). ATP-competitive RAF inhibitors activate ERK signalling(4-7) by transactivating RAF dimers(4). In melanomas with mutant BRAF(V600E), levels of RAS activation are low and these drugs bind to BRAF(V600E) monomers and inhibit their activity. This tumour-specific inhibition of ERK signalling results in a broad therapeutic index and RAF inhibitors have remarkable clinical activity in patients with melanomas that harbour mutant BRAF(V600E)(8). However, resistance invariably develops. Here, we identify a new resistance mechanism. We find that a subset of cells resistant to vemurafenib (PLX4032, RG7204) express a 61-kDa variant form of BRAF(V600E), p61BRAF(V600E), which lacks exons 4-8, a region that encompasses the RAS-binding domain. p61BRAF(V600E) shows enhanced dimerization in cells with low levels of RAS activation, as compared to full-length BRAF(V600E). In cells in which p61BRAF(V600E) is expressed endogenously or ectopically, ERK signalling is resistant to the RAF inhibitor. Moreover, a mutation that abolishes the dimerization of p61BRAF(V600E) restores its sensitivity to vemurafenib. Finally, we identified BRAF(V600E) splicing variants lacking the RAS-binding domain in the tumours of six of nineteen patients with acquired resistance to vemurafenib. These data support the model that inhibition of ERK signalling by RAF inhibitors is dependent on levels of RAS-GTP too low to support RAF dimerization and identify a novel mechanism of acquired resistance in patients: expression of splicing isoforms of BRAF(V600E) that dimerize in a RAS-independent manner.

It is unclear whether extended-release niacin added to simvastatin to raise low levels of high-density lipoprotein (HDL) cholesterol is superior to simvastatin alone in reducing such residual risk. METHODS We randomly assigned eligible patients to receive extended-release niacin, 1500 to 2000 mg per day, or matching placebo. All patients received simvastatin, 40 to 80 mg per day, plus ezetimibe, 10 mg per day, if needed, to maintain an LDL cholesterol level of 40 to 80 mg per deciliter (1.03 to 2.07 mmol per liter). The primary end point was the first event of the composite of death from coronary heart disease, nonfatal myocardial infarction, ischemic stroke, hospitalization for an acute coronary syndrome, or symptom-driven coronary or cerebral revascularization. RESULTS A total of 3414 patients were randomly assigned to receive niacin (1718) or placebo (1696). The trial was stopped after a mean follow-up period of 3 years owing to a lack of efficacy. At 2 years, niacin therapy had significantly increased the median HDL cholesterol level from 35 mg per deciliter (0.91 mmol per liter) to 42 mg per deciliter (1.08 mmol per liter), lowered the triglyceride level from 164 mg per deciliter (1.85 mmol per liter) to 122 mg per deciliter (1.38 mmol per liter), and lowered the LDL cholesterol level from 74 mg per deciliter (1.91 mmol per liter) to 62 mg per deciliter (1.60 mmol per liter). The primary end point occurred in 282 patients in the niacin group (16.4%) and in 274 patients in the placebo group (16.2%) (hazard ratio, 1.02; 95% confidence interval, 0.87 to 1.21; P = 0.79 by the log-rank test). CONCLUSIONS Among patients with atherosclerotic cardiovascular disease and LDL cholesterol levels of less than 70 mg per deciliter (1.81 mmol per liter), there was no incremental clinical benefit from the addition of niacin to statin therapy during a 36-month follow-up period, despite significant improvements in HDL cholesterol and triglyceride levels.

An evaluation of previously generated T-Cre-mediated Fgf8-deficient mice (T-Cre; Fgf8(flox/Delta 2,3) mice), which lack Fgf8 expression in the mesoderm, revealed that the cranial region of the Wolffian duct degenerated prematurely and the cranial mesonephric tubules were missing. As a result, the epididymis, vas deferens and efferent ductules were largely absent in mutant mice. Rarb2-Cre was used to eliminate FGF8 from the mesonephric tubules but to allow expression in the adjacent somites. These mutants retained the cranial end of the Wolffian duct and formed the epididymis and vas deferens, but failed to elaborate the efferent ductules, indicating that Fgf8 expression by the mesonephric tubules is required specifically for the formation of the ductules. Ret knockout mice do not form the ureteric bud, a caudal outgrowth of the Wolffian duct and progenitor for the collecting duct network in the kidney, but they do develop the cranial end normally. This indicates that Fgf8, but not Ret, expression is essential to the outgrowth of the cranial mesonephric tubules from the Wolffian duct and to the development of major portions of the sex accessory tissues in the male reproductive tract. Mechanistically, FGF8 functions upstream of Lhx1 expression in forming the nephron, and analysis of Fgf8 mutants similarly shows deficient Lhx1 expression in the mesonephric tubules. These results demonstrate a multifocal requirement for FGF8 in establishing the male reproductive tract ducts and implicate Lhx1 signaling in tubule elongation.

These neurons originate prenatally in the nasal placode and migrate into the forebrain along the olfactory-vomeronasal nerves. Alterations in this migratory process lead to defective GnRH-1 secretion, resulting in heterogeneous genetic disorders such as idiopathic hypogonadotropic hypogonadism (IHH), and other reproductive diseases characterized by the reduction or failure of sexual competence. Combining mouse genetics with in vitro models, we demonstrate that Semaphorin 7A (Sema7A) is essential for the development of the GnRH-1 neuronal system. Loss of Sema7A signaling alters the migration of GnRH-1 neurons, resulting in significantly reduced numbers of these neurons in the adult brain as well as in reduced gonadal size and subfertility. We also show that GnRH-1 cells differentially express the Sema7 receptors beta 1-integrin and Plexin C1 as a function of their migratory stage, whereas the ligand is robustly expressed along developing olfactory/vomeronasal fibers. Disruption of Sema7A function in vitro inhibits beta 1-integrin-mediated migration. Analysis of Plexin C1(-/-) mice did not reveal any difference in the migratory process of GnRH-1 neurons, indicating that Sema7A mainly signals through b1-integrin to regulate GnRH-1 cell motility. In conclusion, we have identified Sema7A as a gene implicated in the normal development of the GnRH-1 system in mice and as a genetic marker for the elucidation of some forms of GnRH-1 deficiency in humans.

In a discovery cohort of 1804 melanoma cases and 1026 controls, we identified loci at chromosomes 15q13.1 (HERC2/OCA2 region) and 16q24.3 (MC1R) regions that reached genome-wide significance within this study and also found strong evidence for genetic effects on susceptibility to melanoma from markers on chromosome 9p21.3 in the p16/ARF region and on chromosome 1q21.3 (ARNT/LASS2/ANXA9 region). The most significant single-nucleotide polymorphisms (SNPs) in the 15q13.1 locus (rs1129038 and rs12913832) lie within a genomic region that has profound effects on eye and skin color; notably, 50% of variability in eye color is associated with variation in the SNP rs12913832. Because eye and skin colors vary across European populations, we further evaluated the associations of the significant SNPs after carefully adjusting for European substructure. We also evaluated the top 10 most significant SNPs by using data from three other genome-wide scans. Additional in silico data provided replication of the findings from the most significant region on chromosome 1q21.3 rs7412746 (P = 6 x 10(-10)). Together, these data identified several candidate genes for additional studies to identify causal variants predisposing to increased risk for developing melanoma.

In this study, we investigate the expression and localization of the Shh signaling receptors, Patched (Ptch) and Smoothened (Smo), in the hippocampal neurons of young and mature rats. Reverse transcriptase-polymerase chain reaction and immunoblotting analyses show that the expression of Ptch and Smo remains at a moderate level in young postnatal and adult brains. By using immunofluorescence light microscopy and immunoelectron microscopy, we examine the spatial distribution of Ptch and Smo within the hippocampal neurons. In young developing neurons, Ptch and Smo are present in the processes and are clustered at their growth cones. In mature neurons, Ptch and Smo are concentrated in dendrites, spines, and postsynaptic sites. Synaptic Ptch and Smo often co-exist with unusual structuressynaptic spinules and autophagosomes. Our results reveal the anatomical organization of the Shh receptors within both the young and the mature hippocampal neurons. J. Comp. Neurol. 519:3684-3699, 2011. (c) 2011 Wiley-Liss, Inc.

TI IL28B rs12979860 Genotype and Spontaneous Clearance of Hepatitis C Virus in a Multi-Ethnic Cohort of Injection Drug Users: Evidence for a Supra-Additive Association SO JOURNAL OF INFECTIOUS DISEASES LA English DT Article ID POLYMORPHISM; INFECTION AB Among 1369 Urban Health Study participants, we evaluated genetic models for the association of IL28B genotype (rs12979860 and rs8099917) with hepatitis C virus (HCV) clearance. For rs12979860, adjusted odds ratios for spontaneous HCV clearance were as follows: IL28B-CC, 3.88 (P < .001); IL28B-CT, 1.48 (P = .08). On the basis of Akaike information criteria values and chi(2) tests, a supra-additive (quadratic) model fit these data best. Models based on rs8099917 provided poorer fit. Evidence that a supra-additive rs12979860-based model best fits the association of IL28B-genotype with HCV clearance may improve clinical prediction models and foster a better understanding of functional mechanisms underlying this association.

We used positron emission tomography and computed tomography (PET/CT) to identify inflammatory patterns as predictors for the outcome of MPXV disease in NHPs. Two NHPs were sublethally inoculated by the intravenous (IV) or intrabronchial (IB) routes and imaged sequentially using fluorine-18 fluorodeoxyglucose ((18)FDG) uptake as a nonspecific marker of inflammation/immune activation. Inflammation was observed in the lungs of IB-infected NHPs, and bilobular involvement was associated with morbidity. Lymphadenopathy and immune activation in the axillary lymph nodes were evident in IV- and IB-infected NHPs. Interestingly, the surviving NHPs had significant (18)FDG uptake in the axillary lymph nodes at the time of MPXV challenge with no clinical signs of illness, suggesting an association between preexisting immune activation and survival. Molecular imaging identified patterns of inflammation/immune activation that may allow risk assessment of monkeypox disease.

TI Analysis of Genetic Linkage of HIV From Couples Enrolled in the HIV Prevention Trials Network 052 Trial SO JOURNAL OF INFECTIOUS DISEASES LA English DT Article ID MOLECULAR EPIDEMIOLOGY; INFECTION; IDENTIFICATION; EVOLUTIONARY; TRANSMISSION AB Methods. Linkage was assessed using phylogenetic analysis of HIV pol sequences and Bayesian analysis of genetic distances between pol sequences from index-partner pairs and controls. Selected samples were also analyzed using next-generation sequencing (env region). Results. In 29 of the 38 (76.3%) cases analyzed, the index was the likely source of the partner's HIV infection (linked). In 7 cases (18.4%), the partner was most likely infected from a source other than the index participant (unlinked). In 2 cases (5.3%), linkage status could not be definitively established. Conclusions. Nearly one-fifth of the seroconversion events in HPTN 052 were unlinked. The association of early ART and reduced HIV transmission was stronger when the analysis included only linked events. This underscores the importance of assessing the genetic linkage of HIV seroconversion events in HIV prevention studies involving serodiscordant couples.

This assay is based on the oxidation of G6P in the presence of glucose-6-phosphate dehydrogenase (G6PD) and nicotinamide adenine dinucleotide phosphate (NADP(+)); the NADPH thereby generated reduces the tetrazolium salt WST-1 [2-(4-indophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H tetrazolium, monosodium salt] to water-soluble yellow-colored formazan with 1-methoxy-5-methylphenazium methylsulfate (1-mPMS) as an electron carrier. The assay is optimized for reaction buffer pH, enzyme/dye concentration, and reaction time course. The limit of detection of the assay is 0.15 mu M (15 pmol/well). The usefulness of the assay is demonstrated by the accurate measurement of the G6P concentration in fetal bovine serum (FBS). (C) 2011 Elsevier Inc. All rights reserved.

Periodic variation of the channel width leads to the slowdown of diffusion along the channel axis. There are several approximate approaches, which allow one to analyze the slowdown. We use these approaches to derive five expressions for the effective diffusion coefficient of a point Brownian particle in the channel. To check the accuracy of the expressions we compare their predictions with the effective diffusion coefficient obtained from Brownian dynamics simulations. (C) 2011 American Institute of Physics.

TI PEGylation Potentiates the Effectiveness of an Antagonistic Peptide That Targets the EphB4 Receptor with Nanomolar Affinity SO PLOS ONE LA English DT Article ID COLORECTAL-CANCER PROGRESSION; GROWTH-FACTOR WITHDRAWAL; TUMOR-GROWTH; TYROSINE KINASE; MELANOMA-CELLS; BLOOD-VESSELS; IN-VIVO; VASCULAR MORPHOGENESIS; DRUG-DELIVERY; ANGIOGENESIS AB The EphB4 receptor tyrosine kinase together with its preferred ligand, ephrin-B2, regulates a variety of physiological and pathological processes, including tumor progression, pathological forms of angiogenesis, cardiomyocyte differentiation and bone remodeling. We previously reported the identification of TNYL-RAW, a 15 amino acid-long peptide that binds to the ephrin-binding pocked of EphB4 with low nanomolar affinity and inhibits ephrin-B2 binding. Although ephrin-B2 interacts promiscuously with all the EphB receptors, the TNYL-RAW peptide is remarkably selective and only binds to EphB4. Therefore, this peptide is a useful tool for studying the biological functions of EphB4 and for imaging EphB4-expressing tumors. Furthermore, TNYL-RAW could be useful for treating pathologies involving EphB4-ephrin-B2 interaction. However, the peptide has a very short half-life in cell culture and in the mouse blood circulation due to proteolytic degradation and clearance by the kidneys and reticuloendothelial system. To overcome these limitations, we have modified TNYL-RAW by fusion with the Fc portion of human IgG1, complexation with streptavidin or covalent coupling to a 40 KDa branched polyethylene glycol (PEG) polymer. These modified forms of TNYL-RAW all have greatly increased stability in cell culture, while retaining high binding affinity for EphB4. Furthermore, PEGylation most effectively increases peptide half-life in vivo. Consistent with increased stability, submicromolar concentrations of PEGylated TNYL-RAW effectively impair EphB4 activation by ephrin-B2 in cultured B16 melanoma cells as well as capillary-like tube formation and capillary sprouting in co-cultures of endothelial and epicardial mesothelial cells. Therefore, PEGylated TNYL-RAW may be useful for inhibiting pathological forms of angiogenesis through a novel mechanism involving disruption of EphB4-ephrin-B2 interactions between endothelial cells and supporting perivascular mesenchymal cells. Furthermore, the PEGylated peptide is suitable for other cell culture and in vivo applications requiring prolonged EphB4 receptor targeting.

Less clear is how different microtubule-based and actin-based motors work together to support this growth. Here we examined the role of myosin-V (MYOV) in hyphal growth. MYOV-depleted cells form elongated hyphae, but the rate of hyphal elongation is significantly reduced. In addition, although wild type cells without microtubules still undergo polarized growth, microtubule disassembly abolishes polarized growth in MYOV-depleted cells. Thus, MYOV is essential for polarized growth in the absence of microtubules. Moreover, while a triple kinesin null mutant lacking kinesin-1 (KINA) and two kinesin-3s (UNCA and UNCB) undergoes hyphal elongation and forms a colony, depleting MYOV in this triple mutant results in lethality due to a severe defect in polarized growth. These results argue that MYOV, through its ability to transport secretory cargo, can support a significant amount of polarized hyphal tip growth in the absence of any microtubule-based transport. Finally, our genetic analyses also indicate that KINA (kinesin-1) rather than UNCA (kinesin-3) is the major kinesin motor that supports polarized growth in the absence of MYOV.

TI MAP Kinases Couple Hindbrain-Derived Catecholamine Signals to Hypothalamic Adrenocortical Control Mechanisms during Glycemia-Related Challenges SO JOURNAL OF NEUROSCIENCE LA English DT Article ID CORTICOTROPIN-RELEASING HORMONE; MITOGEN-ACTIVATED PROTEIN; PITUITARY-ADRENAL AXIS; INSULIN-INDUCED HYPOGLYCEMIA; PARAVENTRICULAR NUCLEUS; PARVOCELLULAR NEURONS; GENE-EXPRESSION; IN-VITRO; SYNTHESIZING NEURONS; RAT HYPOTHALAMUS AB Physiological responses to hypoglycemia, hyperinsulinemia, and hyperglycemia include a critical adrenocortical component that is initiated by hypothalamic control of the anterior pituitary and adrenal cortex. These adrenocortical responses ensure appropriate long-term glucocorticoid-mediated modifications to metabolism. Despite the importance of these mechanisms to disease processes, how hypothalamic afferent pathways engage the intracellular mechanisms that initiate adrenocortical responses to glycemia-related challenges are unknown. This study explores these mechanisms using network-and cellular-level interventions in in vivo and ex vivo rat preparations. Results show that a hindbrain-originating catecholamine afferent system selectively engages a MAP kinase pathway in rat paraventricular hypothalamic CRH (corticotropin-releasing hormone) neuroendocrine neurons shortly after vascular insulin and 2-deoxyglucose challenges. In turn, this MAP kinase pathway can control both neuroendocrine neuronal firing rate and the state of CREB phosphorylation in a reduced ex vivo paraventricular hypothalamic preparation, making this signaling pathway an ideal candidate for coordinating CRH synthesis and release. These results establish the first clear structural and functional relationships linking neurons in known nutrient-sensing regions with intracellular mechanisms in hypothalamic CRH neuroendocrine neurons that initiate the adrenocortical response to various glycemia-related challenges.

Rates are higher than those of other developed countries and have stagnated over the past decade. There is significant racial disparity in the rate of stillbirth that is unexplained. Objective To ascertain the causes of stillbirth in a population that is diverse by race/ethnicity and geography. Design, Setting, and Participants A population-based study from March 2006 to September 2008 with surveillance for all stillbirths at 20 weeks or later in 59 tertiary care and community hospitals in 5 catchment areas defined by state and county boundaries to ensure access to at least 90% of all deliveries. Termination of a live fetus was excluded. Standardized evaluations were performed at delivery. Main Outcome Measures Medical history, fetal postmortem and placental pathology, karyotype, other laboratory tests, systematic assignment of causes of death. Results Of 663 women with stillbirth enrolled, 500 women consented to complete postmortem examinations of 512 neonates. A probable cause of death was found in 312 stillbirths (60.9%; 95% CI, 56.5%-65.2%) and possible or probable cause in 390 (76.2%; 95% CI, 72.2%-79.8%). The most common causes were obstetric conditions (150 [29.3%; 95% CI, 25.4%-33.5%]), placental abnormalities (121 [23.6%; 95% CI, 20.1%-27.6%]), fetal genetic/structural abnormalities (70 [13.7%; 95% CI, 10.9%-17.0%]), infection (66 [12.9%; 95% CI, 10.2%-16.2%]), umbilical cord abnormalities (53 [10.4%; 95% CI, 7.9%-13.4%]), hypertensive disorders (47 [9.2%; 95% CI, 6.9%-12.1%]), and other maternal medical conditions (40 [7.8%; 95% CI, 5.7%-10.6%]). A higher proportion of stillbirths in non-Hispanic black women compared with non-Hispanic white and Hispanic ones was associated with obstetric complications (43.5% [50] vs 23.7% [85]; difference, 19.8%; 95% CI, 9.7%-29.9%; P < .001) and infections (25.2% [29] vs 7.8% [28]; difference, 17.4%; 95% CI, 9.0%-25.8%; P < .001). Stillbirths occurring intrapartum and early in gestation were more common in non-Hispanic black women. Sources most likely to provide positive information regarding cause of death were placental histology (268 [52.3%; 95% CI, 47.9%-56.7%]), perinatal postmortem examination (161 [31.4%; 95% CI, 27.5%-35.7%]), and karyotype (32 of 357 with definitive results [9%; 95% CI, 6.3%-12.5%]). Conclusions A systematic evaluation led to a probable or possible cause in the majority of stillbirths. Obstetric conditions and placental abnormalities were the most common causes of stillbirth, although the distribution differed by race/ethnicity.

Most large studies of risk factors for stillbirth use vital statistics with limited data. Objective To determine the relation between stillbirths and risk factors that could be ascertained at the start of pregnancy, particularly the contribution of these factors to racial disparities. Design, Setting, and Participants Multisite population-based case-control study conducted between March 2006 and September 2008. Fifty-nine US tertiary care and community hospitals, with access to at least 90% of deliveries within 5 catchment areas defined by state and county lines, enrolled residents with deliveries of 1 or more stillborn fetuses and a representative sample of deliveries of only live-born infants, over-sampled for those at less than 32 weeks' gestation and those of African descent. Main Outcome Measure Stillbirth. Results Analysis included 614 case and 1816 control deliveries. In multivariate analyses, the following factors were independently associated with stillbirth: non-Hispanic black race/ethnicity (23.1% stillbirths, 11.2% live births) (vs non-Hispanic whites; adjusted odds ratio [AOR], 2.12 [95% CI, 1.41-3.20]); previous stillbirth (6.7% stillbirths, 1.4% live births); nulliparity with (10.5% stillbirths, 5.2% live births) and without (34.0% stillbirths, 29.7% live births) previous losses at fewer than 20 weeks' gestation (vs multiparity without stillbirth or previous losses; AOR, 5.91 [95% CI, 3.18-11.00]; AOR, 3.13 [95% CI, 2.06-4.75]; and AOR, 1.98 [95% CI, 1.51-2.60], respectively); diabetes (5.6% stillbirths, 1.6% live births) (vs no diabetes; AOR, 2.50 [95% CI, 1.39-4.48]); maternal age 40 years or older (4.5% stillbirths, 2.1% live births) (vs age 20-34 years; AOR, 2.41 [95% CI, 1.24-4.70]); maternal AB blood type (4.9% stillbirths, 3.0% live births) (vs type O; AOR, 1.96 [95% CI, 1.16-3.30]); history of drug addiction (4.5% stillbirths, 2.1% live births) (vs never use; AOR, 2.08 [95% CI, 1.12-3.88]); smoking during the 3 months prior to pregnancy (<10 cigarettes/d, 10.0% stillbirths, 6.5% live births) (vs none; AOR, 1.55 [95% CI, 1.02-2.35]); obesity/overweight (15.5% stillbirths, 12.4% live births) (vs normal weight; AOR, 1.72 [95% CI, 1.22-2.43]); not living with a partner (25.4% stillbirths, 15.3% live births) (vs married; AOR, 1.62 [95% CI, 1.15-2.27]); and plurality (6.4% stillbirths, 1.9% live births) (vs singleton; AOR, 4.59 [95% CI, 2.63-8.00]). The generalized R-2 was 0.19, explaining little of the variance. Conclusion Multiple risk factors that would have been known at the time of pregnancy confirmation were associated with stillbirth but accounted for only a small amount of the variance in this outcome.

TI Cancer Risk Among Patients With Myotonic Muscular Dystrophy SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION LA English DT Article ID TRIPLET REPEAT EXPANSION; BASAL-CELL CARCINOMA; HUNTINGTON-DISEASE; TRUE ASSOCIATION; MISMATCH-REPAIR; CTG REPEAT; TYPE-2; GENE; RNA; INSTABILITY AB Context Myotonic muscular dystrophy (MMD) is an autosomal-dominant multisystem neuromuscular disorder characterized by unstable nucleotide repeat expansions. Case reports have suggested that MMD patients may be at increased risk of malignancy, putative risks that have never been quantified. Objective To quantitatively evaluate cancer risk in patients with MMD, overall and by sex and age. Design, Setting, and Participants We identified 1658 patients with an MMD discharge diagnosis in the Swedish Hospital Discharge Register or Danish National Patient Registry between 1977 and 2008. We linked these patients to their corresponding cancer registry. Patients were followed up from date of first MMD-related inpatient or outpatient contact to first cancer diagnosis, death, emigration, or completion of cancer registration. Main Outcome Measures Risks of all cancers combined and by anatomic site, stratified by sex and age. Results One hundred four patients with an inpatient or outpatient discharge diagnosis of MMD developed cancer during postdischarge follow-up. This corresponds to an observed cancer rate of 73.4 per 10 000 person-years in MMD vs an expected rate of 36.9 per 10 000 person-years in the general Swedish and Danish populations combined (standardized incidence ratio [SIR], 2.0; 95% CI, 1.6-2.4). Specifically, we observed significant excess risks of cancers of the endometrium (n=11; observed rate, 16.1/10 000 person-years; SIR, 7.6; 95% CI, 4.0-13.2), brain (n=7; observed rate, 4.9/10 000 person-years; SIR, 5.3; 95% CI, 2.3-10.4), ovary (n=7; observed rate, 10.3/10 000 person-years; SIR, 5.2; 95% CI, 2.3-10.2), and colon (n=10; observed rate, 7.1/10 000 person-years; SIR, 2.9; 95% CI, 1.5-5.1). Cancer risks were similar in women and men after excluding genital organ tumors (SIR, 1.9; 95% CI, 1.4-2.5, vs SIR, 1.8; 95% CI, 1.3-2.5, respectively; P=.81 for heterogeneity; observed rates, 64.5 and 47.7 per 10 000 person-years in women and men, respectively). The same pattern of cancer excess was observed first in the Swedish and then in the Danish cohorts, which were studied sequentially and initially analyzed independently. Conclusion Patients with MMD identified from the Swedish and Danish patient registries were at increased risk of cancer both overall and for selected anatomic sites.

In southern coastal Kenya, bed net use was negligible in 1997-1998 when Anopheles funestus and An. gambiae s.s. were the primary malaria vectors, with An. arabiensis and Anopheles merus playing a secondary role. Since 2001, bed net use has increased progressively and reached high levels by 20092010 with corresponding decline in malaria transmission. Methods: To evaluate the impact of the substantial increase in household bed net use within this area on vector density, vector composition, and human-vector contact, indoor and outdoor resting mosquitoes were collected in the same region during 2009-2010 using pyrethrum spray catches and clay pots for indoor and outdoor collections respectively. Information on bed net use per sleeping spaces and factors influencing mosquito density were determined in the same houses using Poisson regression analysis. Species distribution was determined, and number of mosquitoes per house, human-biting rates (HBR), and entomological inoculation rate (EIR) were compared to those reported for the same area during 1997-1998, when bed net coverage had been minimal. Results: Compared to 1997-1998, a significant decline in the relative proportion of An. gambiae s.s. among collected mosquitoes was noted, coupled with a proportionate increase of An. arabiensis. Following > 5 years of 60-86% coverage with bed nets, the density, human biting rate and EIR of indoor resting mosquitoes were reduced by more than 92% for An. funestus and by 75% for An. gambiae s.l. In addition, the host feeding choice of both vectors shifted more toward non-human vertebrates. Besides bed net use, malaria vector abundance was also influenced by type of house construction and according to whether one sleeps on a bed or a mat (both of these are associated with household wealth). Mosquito density was positively associated with presence of domestic animals. Conclusions: These entomological indices indicate a much reduced human biting rate and a diminishing role of An. gambiae s. s. in malaria transmission following high bed net coverage. While increasing bed net coverage beyond the current levels may not significantly reduce the transmission potential of An. arabiensis, it is anticipated that increasing or at least sustaining high bed net coverage will result in a diminished role for An. funestus in malaria transmission.

The dopamine D(1) receptor appears to be involved in these METH-mediated stresses. The purpose of this study was to investigate if dopamine D(1) and D(2) receptors are involved in ER and mitochondrial stresses caused by single-day METH binges in the rat striatum. Male Sprague-Dawley rats received 4 injections of 10 mg/kg of METH alone or in combination with a putative D(1) or D(2) receptor antagonist, SCH23390 or raclopride, respectively, given 30 min prior to each METH injection. Rats were euthanized at various timepoints afterwards. Striatal tissues were used in quantitative RT-PCR and western blot analyses. We found that binge METH injections caused increased expression of the pro-survival genes, BiP/GRP-78 and P58(IPK), in a SCH23390-sensitive manner. METH also caused up-regulation of ER-stress genes, Atf2, Atf3, Atf4, CHOP/Gadd153 and Gadd34. The expression of heat shock proteins ( HSPs) was increased after METH injections. SCH23390 completely blocked induction in all analyzed ER stress-related proteins that included ATF3, ATF4, CHOP/Gadd153, HSPs and caspase-12. The dopamine D(2)-like antagonist, raclopride, exerted small to moderate inhibitory influence on some METH-induced changes in ER stress proteins. Importantly, METH caused decreases in the mitochondrial anti-apoptotic protein, Bcl-2, but increases in the pro-apoptotic proteins, Bax, Bad and cytochrome c, in a SCH23390-sensitive fashion. In contrast, raclopride provided only small inhibition of METH-induced changes in mitochondrial proteins. These findings indicate that METH-induced activation of striatal ER and mitochondrial stress pathways might be more related to activation of SCH23390-sensitive receptors.

High-resolution EEGs were recorded in 15 FHD patients and 15 healthy volunteers at rest and during a simple sequential finger tapping task. Mutual information (MI) values of wavelet coefficients were estimated to create an association matrix between EEG electrodes, and to produce a series of adjacency matrices or graphs, G, by thresholding with network cost. Efficiency measures of small-world networks were assessed. As a result, we found that FHD patients have economical small-world properties in their brain functional networks in the alpha and beta bands. During a motor task, in the beta band network, FHD patients have decreased efficiency of small-world networks, whereas healthy volunteers increase efficiency. Reduced efficient beta band network in FHD patients during the task was consistently observed in global efficiency, cost-efficiency, and maximum cost-efficiency. This suggests that the beta band functional cortical network of FHD patients is reorganized even during a task that does not induce dystonic symptoms, representing a loss of long-range communication and abnormal functional integration in large-scale brain functional cortical networks. Moreover, negative correlations between efficiency measures and duration of disease were found, indicating that the longer duration of disease, the less efficient the beta band network in FHD patients. In regional efficiency analysis, FHD patients at rest have high regional efficiency at supplementary motor cortex (SMA) compared with healthy volunteers; however, it is diminished during the motor task, possibly reflecting abnormal inhibition in FHD patients. The present study provides the first evidence with graph theory for abnormal reconfiguration of brain functional networks in FHD during motor task.

A fragment of Pmel17, the repeat domain (RPT) rich in glutamic acids, forms amyloid only at mildly acidic pH. Unlike pathological amyloids, these fibrils dissolve at neutral pH, supporting a reversible aggregation disaggregation process. Here, we study RPT dissolution using atomic force microscopy and solution-state nuclear magnetic resonance spectroscopy. Our results reveal asymmetric fibril disassembly proceeding in the absence of intermediates. We suggest that fibril unfolding involves multiple deprotonation events resulting in electrostatic charge repulsion and filament dissolution.

HACs avoid the limited cloning capacity, lack of copy number control, and insertional mutagenesis caused by integration into host chromosomes that plague viral vectors. We previously described a synthetic HAC that can be easily eliminated from cell populations by inactivation of its conditional kinetochore. Here, we demonstrate the utility of this HAC, which has a unique gene acceptor site, for delivery of full-length genes and correction of genetic deficiencies in human cells. A battery of functional tests was performed to demonstrate expression of NBS1 and VHL genes from the HAC at physiological levels. We also show that phenotypes arising from stable gene expression can be reversed when cells are "cured" of the HAC by inactivating its kinetochore in proliferating cell populations, a feature that provides a control for phenotypic changes attributed to expression of HAC-encoded genes. This generation of human artificial chromosomes should be suitable for studies of gene function and therapeutic applications.

Yang, Yingzi TI Wnt/beta-catenin signaling is differentially regulated by G alpha proteins and contributes to fibrous dysplasia SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID SUPPRESSES OSTEOGENIC DIFFERENTIATION; MCCUNE-ALBRIGHT-SYNDROME; MESENCHYMAL STEM-CELLS; HIGH-BONE-MASS; BETA-CATENIN; PROMOTES PROLIFERATION; INTESTINAL POLYPOSIS; SKELETAL PROGENITORS; PARATHYROID-HORMONE; WNT AB Skeletal dysplasias are common disabling disorders characterized by aberrant growth of bone and cartilage leading to abnormal skeletal structures and functions, often attributable to defects in skeletal progenitor cells. The underlying molecular and cellular mechanisms of most skeletal dysplasias remain elusive. Although the Wnt/beta-catenin signaling pathway is required for skeletal progenitor cells to differentiate along the osteoblastic lineage, inappropriately elevated levels of signaling can also inhibit bone formation by suppressing osteoblast maturation. Here, we investigate interactions of the four major G alpha protein families (G alpha(s), G alpha(i/o), G alpha(q/11), and G alpha(12/13)) with the Wnt/beta-catenin signaling pathway and identify a causative role of Wnt/beta-catenin signaling in fibrous dysplasia (FD) of bone, a disease that exhibits abnormal differentiation of skeletal progenitor cells. The activating G alpha(s) mutations that cause FD potentiated Wnt/beta-catenin signaling, and removal of G alpha(s) led to reduced Wnt/beta-catenin signaling and decreased bone formation. We further show that activation of Wnt/beta-catenin signaling in osteoblast progenitors results in an FD-like phenotype and reduction of beta-catenin levels rescued differentiation defects of FD patient-derived stromal cells. Ga proteins may act at the level of beta-catenin destruction complex assembly by binding Axin. Our results indicate that activated G alpha proteins differentially regulate Wnt/beta-catenin signaling but, importantly, are not required core components of Wnt/beta-catenin signaling. Our data suggest that activated Ga proteins are playing physiologically significant roles during both skeletal development and disease by modulating Wnt/beta-catenin signaling strength.

TI Rapid development of glycan-specific, broad, and potent anti-HIV-1 gp120 neutralizing antibodies in an R5 SIV/HIV chimeric virus infected macaque SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID MONOCLONAL-ANTIBODIES; IN-VITRO; IMMUNODEFICIENCY; PROTECTION; GLYCOPROTEIN; BINDING; SITE; VIVO; 2G12 AB It is widely believed that the induction of a broadly neutralizing antibody (bNAb) response will be a critical component of a successful vaccine against HIV. A significant fraction of HIV-infected individuals mount bNAb responses, providing support for the notion that such responses could be elicited through vaccination. Infection of macaques with simian immunodeficiency virus (SIV) or SIV/HIV chimeric virus (SHIV) has been widely used to model aspects of HIV infection, but to date, only limited bNAb responses have been described. Here, we screened plasma from 14 R5-tropic SHIV-infected macaques for broadly neutralizing activity and identified a macaque with highly potent cross-clade plasma NAb response. Longitudinal studies showed that the development of broad and autologous NAb responses occurred coincidentally in this animal. Serum-mapping studies, using pseudovirus point mutants and antigen adsorption assays, indicated that the plasma bNAbs are specific for epitopes that include carbohydrates and are critically dependent on the glycan at position 332 of Env gp120. The results described herein provide insight into the development and evolution of a broad response, suggest that certain bNAb specificities may be more rapidly induced by immunization than others, and provide a potential model for the facile study of the development of bNAb responses.

TI Intraprotomer masking of third variable loop (V3) epitopes by the first and second variable loops (V1V2) within the native HIV-1 envelope glycoprotein trimer SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE envelope glycoprotein trimer; functional complementation; Env trimer structure; cis versus trans ID HUMAN-IMMUNODEFICIENCY-VIRUS; COOPERATIVE SUBUNIT INTERACTIONS; HUMAN MONOCLONAL-ANTIBODY; NEUTRALIZING ANTIBODIES; CLADE-A; TYPE-1; GP120; PARTICLES; ENV; COMPLEMENTATION AB Within the trimeric HIV-1 envelope (Env) spike, the first and second variable loops (V1V2 region) and the third variable loop (V3) of the gp120 subunit play dual roles in antibody recognition, because they contain neutralization epitopes and also participate in epitope masking. The spatial relationships between V1V2 and V3 and the associated mechanisms of epitope masking remain unclear. Here we investigated interactions between these domains using two monoclonal antibodies recognizing distinct conserved linear epitopes that are subject to masking in the functional trimer, which limits their neutralizing activities. Using Env pseudotype virus infection assays, we found that deleting the V1V2 region greatly enhanced neutralization by both antibodies, leading us to consider two alternative models: V1V2 on one gp120 protomer masks V3 on the same protomer (intraprotomer or cis masking) versus on an adjacent protomer (interprotomer or trans masking). Our experimental approach exploited a previously described complementation system wherein two variant Envs harboring different inactivating mutations (one in gp120, the other in gp41) are coexpressed in the same cell; functional Env results only from cooperative interactions within mixed trimers, thereby enabling selective examination of mixed trimer activity. We introduced additional mutations that either promoted (V1V2 deletion, i.e., unmasking) or prevented (GPGR to GPGQ mutation, i.e., epitope destruction) interaction with the antibodies. The observed neutralization sensitivities of mixed trimers produced from various combinations of constructs support the intraprotomer (cis) model of V1V2 masking of V3 epitopes.

We discovered a mutation in an intracellular loop of rNav1.2a (G1079C), which results in a higher apparent affinity for externally applied PaurTx3 and ProTx-II, two voltage sensor toxins isolated from tarantula venom. To explore whether palmitoylation of the introduced cysteine underlies this observation, we compared channel susceptibility to a range of animal toxins in the absence and presence of 2-Br-palmitate, a palmitate analog that prevents palmitate incorporation into proteins, and found that palmitoylation contributes to the increased affinity of PaurTx3 and ProTx-II for G1079C. Further investigations with 2-Br-palmitate revealed that palmitoylation can regulate the gating and pharmacology of wild-type (wt) rNav1.2a. To identify rNav1.2a palmitoylation sites contributing to these phenomena, we substituted three endogenous cysteines predicted to be palmitoylated and found that the gating behavior of this triple cysteine mutant is similar to wt rNav1.2a treated with 2-Br-palmitate. As with chemically depalmitoylated rNav1.2a channels, this mutant also exhibits an increased susceptibility for PaurTx3. Additional mutagenesis experiments showed that palmitoylation of one cysteine in particular (C1182) primarily influences PaurTx3 sensitivity and may enhance the inactivation process of wt rNav1.2a. Overall, our results demonstrate that lipid modifications are capable of altering the gating and pharmacological properties of rNav1.2a.

Our goal was to establish prevalence estimates and correlates of cancer screening, including physician recommendation in older (>75 years), racially diverse adults. Methods: Data were analyzed from the National Health Interview Survey-an annual, in-person, nationwide survey used to track health trends in US civilians. The analytic sample included 49 575 individuals, of whom 1697 were 75 to 79 years old and 2376 were 80 years or older. Screening behaviors were examined according to the US Preventive Services Task Force recommendations for breast, cervical, colorectal, and prostate cancer screening. Results: Among adults aged 75 to 79 years, the percentage screened for cancer was as follows: colorectal, 57%; breast, 62%; cervical, 53%; and prostate, 56%. Among those 80 years or older, rates of screening ranged from a low of 38% for cervical cancer to a high of 50% for breast cancer. Although unadjusted screening prevalence rates differed by race/ethnicity, these differences were accounted for by low education attainment in the multivariate logistic regression model. Physician recommendation for a specific test was the largest predictor of screening. Over 50% of men and women older than 75 years report that their physicians continue to recommend screening. Conclusion: A high percentage of older adults continue to be screened in the face of ambiguity of recommendations for this group.

Here we show that the psm-mec gene is found frequently among methicillin-resistant Staphylococcus aureus (MRSA) strains of SCCmec types II, III, and VIII, and is a conserved part of the class A mec gene complex. Controlled expression of AgrA versus RNAIII in agr mutants of all 3 psm-mec-positive SCCmec types demonstrated that expression of psm-mec, which is highly variable, is controlled by AgrA in an RNAIII-independent manner. Furthermore, psm-mec isogenic deletion mutants showed only minor changes in PSM alpha peptide production and unchanged (or, as previously described, diminished) virulence compared to the corresponding wild-type strains in a mouse model of skin infection. This indicates that the recently reported regulatory impact of the psm-mec locus on MRSA virulence, which is opposite to that of the PSM-mec peptide and likely mediated by a regulatory RNA, is minor when analyzed in the original strain background. Our study gives new insight in the distribution, regulation, and role in virulence of the PSM-mec peptide and the psm-mec gene locus. C1 [Chatterjee, Som S.; Joo, Hwang-Soo; Cheung, Gordon Y.

Methodology and Principal Findings: In vitro antitumor activity was determined in NCI-60 cancer cell line panel using cell viability assay. In vivo antitumor activity was determined in parallel with NSC-741909 (oncrasin-60) in xenograft tumors established in nude mice from A498, a human renal cancer cell line. Changes in gene expression levels and signaling pathway activities upon treatment with NSC-743380 were analyzed in breast and renal cancer cells by Western blot analysis. Apoptosis was demonstrated by Western blot analysis and flow cytometric analysis. NSC-743380 is highly active against a subset of cancer cell lines derived from human lung, colon, ovary, kidney, and breast cancers. The 50% growth-inhibitory concentration (GI(50)) for eight of the most sensitive cell lines was <= 10 nM. In vivo study showed that NSC-743380 has a better safety profile and greater antitumor activity than NSC-741909. Treatment with NSC-743380 caused complete regression of A498 xenograft tumors in nude mice at the tested doses ranging from 67 mg/kg to 150 mg/kg. Mechanistic characterization revealed that NSC-743380 suppressed the phosphorylation of C-terminal domain of RNA polymerase II, induced JNK activation, inhibited JAK2/STAT3 phosphorylation and suppressed cyclin D1 expression in sensitive human cancer cells. Blocking JNK activation or overexpression of constitutively active STAT3 partially blocked NSC-743380-induced antitumor activity. Conclusions: NSC-743380 induces antitumor activity through modulation of functions in multiple cancer related pathways and could be a potential anticancer agent for some solid tumors.

TI Delayed Imitation of Lipsmacking Gestures by Infant Rhesus Macaques (Macaca mulatta) SO PLOS ONE LA English DT Article ID NEONATAL IMITATION; TONGUE PROTRUSION; FACIAL GESTURES; MANUAL GESTURES; NEURONS AB Human infants are capable of accurately matching facial gestures of an experimenter within a few hours after birth, a phenomenon called neonatal imitation. Recent studies have suggested that rather than being a simple reflexive-like behavior, infants exert active control over imitative responses and 'provoke' previously imitated gestures even after a delay of up to 24 h. Delayed imitation is regarded as the hallmark of a sophisticated capacity to control and flexibly engage in affective communication and has been described as an indicator of innate protoconversational readiness. However, we are not the only primates to exhibit neonatal imitation, and delayed imitation abilities may not be uniquely human. Here we report that 1-week-old infant rhesus macaques (Macaca mulatta) who show immediate imitation of a lipsmacking gesture also show delayed imitation of lipsmacking, facilitated by a tendency to refrain from lipsmacking toward a still face during baseline measurements. Individual differences in delayed imitation suggest that differentially matured cortical mechanisms may be involved, allowing some newborns macaques to actively participate in communicative exchanges from birth. Macaque infants are endowed with basic social competencies of intersubjective communication that indicate cognitive and emotional commonality between humans and macaques, which may have evolved to nurture an affective mother-infant relationship in primates.

This study relies on simple subcellular fractionation used to obtain soluble- and membrane-enriched fractions followed by 2-dimensional liquid chromatography (2D-LC) separation and tandem mass spectrometry (MS/MS). The cells were collected using a brushing technique applied on NE of clinically evaluated volunteers. Subsequently, the soluble- and the membrane-protein enriched fractions were prepared and analyzed in parallel using 2D-LC-MS/MS. In a set of 1482 identified proteins, 947 (63.9%) proteins were found to be associated to membrane fraction. Grand average hydropathy value index (GRAVY) analysis, the transmembrane protein mapping and annotations of primary location deposited in the Human Protein Reference Database (HPRD) confirmed an enrichment of hydrophobic proteins on this dataset. Ingenuity Pathway Analysis (IPA) of soluble fraction revealed an enrichment of molecular and cellular functions associated with cell death, protein folding and drug metabolism while in membrane fraction showed an enrichment of functions associated with molecular transport, protein trafficking and cell-to-cell signaling and interaction. The IPA showed similar enrichment of functions associated with cellular growth and proliferation in both soluble and membrane subproteomes. This finding was in agreement with protein content analysis using exponentially modified protein abundance index (emPAI). A comparison of our data with previously published studies focusing on respiratory tract epithelium revealed similarities related to identification of proteins associated with physical barrier function and immunological defence. In summary, we extended the NE molecular profile by identifying and characterizing proteins associated to pivotal functions of a respiratory epithelium, including the control of fluid volume and ionic composition at the airways' surface, physical barrier maintenance, detoxification and immunological defence. The extent of similarities supports the applicability of a less invasive analysis of NE to assess prognosis and treatment response of lung diseases such as asthma, cystic fibrosis and chronic obstructive pulmonary disease.

TI Malaria Infections Do Not Compromise Vaccine-Induced Immunity against Tuberculosis in Mice SO PLOS ONE LA English DT Article ID CALMETTE-GUERIN VACCINE; MYCOBACTERIUM-TUBERCULOSIS; PROTECTIVE IMMUNITY; BOVIS BCG; ENVIRONMENTAL MYCOBACTERIA; PUBLISHED LITERATURE; PLASMODIUM-YOELII; TGF-BETA; IN-VITRO; T-CELLS AB Background: Given the considerable geographic overlap in the endemic regions for malaria and tuberculosis, it is probable that co-infections with Mycobacterium tuberculosis and Plasmodium species are prevalent. Thus, it is quite likely that both malaria and TB vaccines may be used in the same populations in endemic areas. While novel vaccines are currently being developed and tested individually against each of these pathogens, the efficacy of these vaccines has not been evaluated in co-infection models. To further assess the effectiveness of these new immunization strategies, we investigated whether co-infection with malaria would impact the anti-tuberculosis protection induced by four different types of TB vaccines in a mouse model of pulmonary tuberculosis. Principal Findings: Here we show that the anti-tuberculosis protective immunity induced by four different tuberculosis vaccines was not impacted by a concurrent infection with Plasmodium yoelii NL, a nonlethal form of murine malaria. After an aerogenic challenge with virulent M. tuberculosis, the lung bacterial burdens of vaccinated animals were not statistically different in malaria infected and malaria naive mice. Multi-parameter flow cytometric analysis showed that the frequency and the median fluorescence intensities (MFI) for specific multifunctional T (MFT) cells expressing IFN-gamma, TNF-alpha, and/or IL-2 were suppressed by the presence of malaria parasites at 2 weeks following the malaria infection but was not affected after parasite clearance at 7 and 10 weeks post-challenge with P. yoelii NL. Conclusions: Our data indicate that the effectiveness of novel TB vaccines in protecting against tuberculosis was unaffected by a primary malaria co-infection in a mouse model of pulmonary tuberculosis. While the activities of specific MFT cell subsets were reduced at elevated levels of malaria parasitemia, the T cell suppression was short-lived. Our findings have important relevance in developing strategies for the deployment of new TB vaccines in malaria endemic areas.

TI Role of Amino Acid Insertions on Intermolecular Forces between Arginine Peptide Condensed DNA Helices IMPLICATIONS FOR PROTAMINE-DNA PACKAGING IN SPERM SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID X-RAY-DIFFRACTION; NUCLEOPROTAMINE STRUCTURE; HYDRATION FORCES; COMPLEXES; FRAGMENTATION; AGGREGATION; SPERMATOZOA; POLYAMINES; MOLECULES; CHROMATIN AB In spermatogenesis, chromatin histones are replaced by arginine-rich protamines to densely compact DNA in sperm heads. Tight packaging is considered necessary to protect the DNA from damage. To better understand the nature of the forces condensing protamine-DNA assemblies and their dependence on amino acid content, the effect of neutral and negatively charged amino acids on DNA-DNA intermolecular forces was studied using model peptides containing six arginines. We have previously observed that the neutral amino acids in salmon protamine decrease the net attraction between protamine-DNA helices compared with the equivalent homo-arginine peptide. Using osmotic stress coupled with x-ray scattering, we have investigated the component attractive and repulsive forces that determine the net attraction and equilibrium interhelical distance as a function of the chemistry, position, and number of the amino acid inserted. Neutral amino acids inserted into hexa-arginine increase the short range repulsion while only slightly affecting longer range attraction. The amino acid content alone of salmon protamine is enough to rationalize the forces that package DNA in sperm heads. Inserting a negatively charged amino acid into hexa-arginine dramatically weakens the net attraction. Both of these observations have biological implications for protamine-DNA packaging in sperm heads. C1 [DeRouchey, Jason E.] Univ Kentucky, Dept Chem, Lexington, KY 40506 USA.

Misexpression of HMGN1 affects the cellular transcription profile; however, the biological function of this protein is still not fully understood. We report that HMGN1 modulates the expression of methyl CpG-binding protein 2 (MeCP2), a DNA-binding protein known to affect neurological functions including autism spectrum disorders, and whose alterations in HMGN1 levels affect the behavior of mice. Quantitative PCR and Western analyses of cell lines and brain tissues from mice that either overexpress or lack HMGN1 indicate that HMGN1 is a negative regulator of MeCP2 expression. Alterations in HMGN1 levels lead to changes in chromatin structure and histone modifications in the MeCP2 promoter. Behavior analyses by open field test, elevated plus maze, Reciprocal Social Interaction, and automated sociability test link changes in HMGN1 levels to abnormalities in activity and anxiety and to social deficits in mice. Targeted analysis of the Autism Genetic Resource Exchange genotype collection reveals a non-random distribution of genotypes within 500 kbp of HMGN1 in a region affecting its expression in families predisposed to autism spectrum disorders. Our results reveal that HMGN1 affects the behavior of mice and suggest that epigenetic changes resulting from altered HMGN1 levels could play a role in the etiology of neurodevelopmental disorders.

TI 14-3-3 Binding and Phosphorylation of Neuroglobin during Hypoxia Modulate Six-to-Five Heme Pocket Coordination and Rate of Nitrite Reduction to Nitric Oxide SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID INOSITOL 1,4,5-TRISPHOSPHATE RECEPTOR; INDUCIBLE FACTOR-1-ALPHA; OXIDATIVE STRESS; GLOBIN FAMILY; PROTEIN; BRAIN; CYTOGLOBIN; ACTIVATION; CELLS; MECHANISMS AB Neuroglobin protects neurons from hypoxia in vitro and in vivo; however, the underlying mechanisms for this effect remain poorly understood. Most of the neuroglobin is present in a hexacoordinate state with proximal and distal histidines in the heme pocket directly bound to the heme iron. At equilibrium, the concentration of the five-coordinate neuroglobin remains very low (0.1-5%). Recent studies have shown that post-translational redox regulation of neuroglobin surface thiol disulfide formation increases the open probability of the heme pocket and allows nitrite binding and reaction to form NO. We hypothesized that the equilibrium between the six-and five-coordinate states and secondary reactions with nitrite to form NO could be regulated by other hypoxia-dependent post-translational modification(s). Protein sequence models identified candidate sites for both 14-3-3 binding and phosphorylation. In both in vitro experiments and human SH-SY5Y neuronal cells exposed to hypoxia and glucose deprivation, we observed that 1) neuroglobin phosphorylation and protein-protein interactions with 14-3-3 increase during hypoxic and metabolic stress; 2) neuroglobin binding to 14-3-3 stabilizes and increases the half-life of phosphorylation; and 3) phosphorylation increases the open probability of the heme pocket, which increases ligand binding (CO and nitrite) and accelerates the rate of anaerobic nitrite reduction to form NO. These data reveal a series of hypoxia-dependent post-translational modifications to neuroglobin that regulate the six-to-five heme pocket equilibrium and heme access to ligands.

TI Spatio-temporal patterns of distribution of West Nile virus vectors in eastern Piedmont Region, Italy SO PARASITES & VECTORS LA English DT Article ID APPROXIMATE BAYESIAN-INFERENCE; NESTED LAPLACE APPROXIMATIONS; SOUTHERN FRANCE; MOSQUITO VECTORS; CULEX; CULICIDAE; ABUNDANCE; CAMARGUE; DIPTERA; DIFFERENTIATION AB Background: West Nile Virus (WNV) transmission in Italy was first reported in 1998 as an equine outbreak near the swamps of Padule di Fucecchio, Tuscany. No other cases were identified during the following decade until 2008, when horse and human outbreaks were reported in Emilia Romagna, North Italy. Since then, WNV outbreaks have occurred annually, spreading from their initial northern foci throughout the country. Following the outbreak in 1998 the Italian public health authority defined a surveillance plan to detect WNV circulation in birds, horses and mosquitoes. By applying spatial statistical analysis (spatial point pattern analysis) and models (Bayesian GLMM models) to a longitudinal dataset on the abundance of the three putative WNV vectors [Ochlerotatus caspius (Pallas 1771), Culex pipiens (Linnaeus 1758) and Culex modestus (Ficalbi 1890)] in eastern Piedmont, we quantified their abundance and distribution in space and time and generated prediction maps outlining the areas with the highest vector productivity and potential for WNV introduction and amplification. Results: The highest abundance and significant spatial clusters of Oc. caspius and Cx. modestus were in proximity to rice fields, and for Cx. pipiens, in proximity to highly populated urban areas. The GLMM model showed the importance of weather conditions and environmental factors in predicting mosquito abundance. Distance from the preferential breeding sites and elevation were negatively associated with the number of collected mosquitoes. The Normalized Difference Vegetation Index (NDVI) was positively correlated with mosquito abundance in rice fields (Oc. caspius and Cx. modestus). Based on the best models, we developed prediction maps for the year 2010 outlining the areas where high abundance of vectors could favour the introduction and amplification of WNV. Conclusions: Our findings provide useful information for surveillance activities aiming to identify locations where the potential for WNV introduction and local transmission are highest. Such information can be used by vector control offices to stratify control interventions in areas prone to the invasion of WNV and other mosquito-transmitted pathogens.

Previous studies suggest that pericardial fat may contribute to myocardial ischemia in symptomatic individuals. However, it is unknown if pericardial fat has similar effects in asymptomatic individuals. Methods: We determined the association between pericardial fat and myocardial blood flow (MBF) in 214 adults with no prior history of cardiovascular disease from the Minnesota field center of the Multi-Ethnic Study of Atherosclerosis (43% female, 56% Caucasian, 44% Hispanic). Pericardial fat volume was measured by computed tomography. MBF was measured by MRI at rest and during adenosine-induced hyperemia. Myocardial perfusion reserve (PR) was calculated as the ratio of hyperemic to resting MBF. Results: Gender-stratified analyses revealed significant differences between men and women including less pericardial fat (71.9 +/- 31.3 vs. 105.2 +/- 57.5 cm(3), p<0.0001) and higher resting MBF (1.12 +/- 0.23 vs. 0.93 +/- 0.19 ml/min/g, p<0.0001), hyperemic MBF (3.49 +/- 0.76 vs. 2.65 +/- 0.72 ml/min/g, p<0.0001), and PR (3.19 +/- 0.78 vs. 2.93 +/- 0.89, p = 0.03) in women. Correlations between pericardial fat and clinical and hemodynamic variables were stronger in women. In women only (p = 0.01 for gender interaction) higher pericardial fat was associated with higher resting MBF (p = 0.008). However, this association was attenuated after accounting for body mass index or rate-pressure product. There were no significant associations between pericardial fat and hyperemic MBF or PR after multivariate adjustment in either gender. In logistic regression analyses there was also no association between impaired coronary vasoreactivity, defined as having a PR <2.5, and pericardial fat in men (OR, 1.18; 95% CI, 0.82-1.70) or women (OR, 1.11; 95% CI, 0.68-1.82). Conclusions: Our data fail to support an independent association between pericardial fat and myocardial perfusion in adults without symptomatic cardiovascular disease. Nevertheless, these findings highlight potentially important differences between asymptomatic and symptomatic individuals with respect to the underlying subclinical disease burden.

TI Global Gene Expression Analysis of Murine Limb Development SO PLOS ONE LA English DT Article ID NAIL-PATELLA SYNDROME; VERTEBRATE LIMB; T-BOX; HINDLIMB IDENTITY; TBX4; SPECIFICATION; BIOCONDUCTOR; OUTGROWTH; MODELS; LMX1B AB Detailed information about stage-specific changes in gene expression is crucial for understanding the gene regulatory networks underlying development and the various signal transduction pathways contributing to morphogenesis. Here we describe the global gene expression dynamics during early murine limb development, when cartilage, tendons, muscle, joints, vasculature and nerves are specified and the musculoskeletal system of limbs is established. We used whole-genome microarrays to identify genes with differential expression at 5 stages of limb development E9.5 to 13.5), during fore- and hind-limb patterning. We found that the onset of limb formation is characterized by an up-regulation of transcription factors, which is followed by a massive activation of genes during E10.5 and E11.5 which levels off at later time points. Among the 3520 genes identified as significantly up-regulated in the limb, we find similar to 30% to be novel, dramatically expanding the repertoire of candidate genes likely to function in the limb. Hierarchical and stage-specific clustering identified expression profiles that are likely to correlate with functional programs during limb development and further characterization of these transcripts will provide new insights into specific tissue patterning processes. Here, we provide for the first time a comprehensive analysis of developmentally regulated genes during murine limb development, and provide some novel insights into the expression dynamics governing limb morphogenesis.

TI TLR agonists and/or IL-15 adjuvanted mucosal Sly vaccine reduced gut CD4(+) memory T cell loss in SIVmac251-challenged rhesus macaques SO VACCINE LA English DT Article DE HIV/SIV vaccine; IL-15; TLR agonist; APOBEG3G; Viral-specific tetramer ID SIMIAN IMMUNODEFICIENCY VIRUS; GASTROINTESTINAL-TRACT; IMMUNE-RESPONSES; HIV-1 INFECTION; HOMEOSTATIC PROLIFERATION; SIVMAC251 INFECTION; VIRAL REPLICATION; CD8-T-CELL MEMORY; TYPE-1 INFECTION; CD4-T-CELL HELP AB Adjuvant plays an important role in increasing and directing vaccine-induced immune responses. In a previous study, we found that a mucosal SIV vaccine using a combination of IL-15 and TLR agonists as adjuvant mediated partial protection against SIVmac251 rectal challenge, whereas neither IL-15 nor TLR agonists alone as an adjuvant impacted the plasma viral loads. In this study, dissociation of CD4(+) T cell preservation with viral loads was observed in the animals vaccinated with adjuvants. Significantly higher levels of memory CD4(+) T cell numbers were preserved after SIVmac251 infection in the colons of the animals vaccinated with vaccine containing any of these adjuvants compared to no adjuvant. When we measured the viral-specific CD8(+) tetramer responses in the colon lamina propria, we found significantly higher levels of gag, tat, and pol epitope tetramer(+) T cell responses in these animals compared to ones without adjuvant, even if some of the animals had similarly high viral loads. Furthermore, this CD4(+) T preservation was positively correlated with increased levels of gag and Tat, but not pol tetramer. T cell responses, and inversely correlated with beta-chemokine expression. The pre-challenged APOBEC3G expression level, which has previously been shown inversely associated with viral loads, was further found positively correlated with CD4(+) T cell number preservation. Overall, these data highlight one unrecognized role of adjuvant in HIV vaccine development, and show that vaccines can produce a surprising discordance between CD4(+) T cell levels and SIV viral load.

We show that a vaccine able to elicit strain-specific non-neutralizing antibodies to this region of gp120 is associated with control of highly pathogenic chimeric SHIV(89.6p) replication in rhesus macaques. The vaccinated animal that had the highest titers of antibodies to the amino terminus portion of VI, prior to challenge, had secondary antibody responses that mediated cell killing by antibody-dependent cellular cytotoxicity (ADCC), as early as 2 weeks after infection and inhibited viral replication by antibody-dependent cell-mediated virus inhibition (ADCVI), by 4 weeks after infection. There was a significant inverse correlation between virus level and binding antibody titers to the envelope protein, (R = -0.83,p = 0.015), and ADCVI (R= -0.84 p = 0.044). Genotyping of plasma virus demonstrated in vivo selection of three SHIV(89.6p) variants with changes in potential N-linked glycosylation sites in Vi. We found a significant inverse correlation between virus levels and titers of antibodies that mediated ADCVI against all the identified V1 virus variants. A significant inverse correlation was also found between neutralizing antibody titers to SHIV(89.6) and virus levels (R = -0.72 p = 0.0050). However, passive inoculation of purified immunoglobulin from animal M316, the macaque that best controlled virus, to a naive macaque, resulted in a low serum neutralizing antibodies and low ADCVI activity that failed to protect from SHIV(89.6p) challenge. Collectively, while our data suggest that anti-envelope antibodies with neutralizing and non-neutralizing Fc(R-dependent activities may be important in the control of SHIV replication, they also demonstrate that low levels of these antibodies alone are not sufficient to protect from infection.
