AB A murine model of Tay-Sachs disease, the prototype of the GM(2) gangliosidoses, was produced through the targeted disruption of the Hexa gene encoding the subunit of alpha-hexosaminidase A. The mice were completely devoid of beta-hexosaminidase A activity and accumulated GM(2) ganglioside in the CNS in an age-dependent manner. Neurons with membranous cytoplasmic bodies (MCBs), identical to those described in Tay-Sachs disease, were identified in the brain of these mice. The neurons with MCBs were periodic acid-Schiff-positive on frozen sections and immunostained with anti-GM(2) ganglioside antibody. However, unlike Tay-Sachs disease in which neurons throughout the brain are affected, the localization of storage neurons in these mice appeared ts be limited to certain regions, i.e., cerebral cortex, the hippocampus, amygdala, hypothalamus, mammillary nucleus, etc. Storage neurons were absent in the olfactory bulb, cerebellar cortex and spinal anterior hems. The difference in the distribution of storage neurons suggests a difference of ganglioside metabolism between humans and mice. This model is useful for the study of the pathogenic mechanisms of neuronal storage in Tay-Sachs disease and for the evaluation of therapeutic strategies.

AB Objectives: To study trends in prevalence and to ascertain risk factors for HIV-1 among sexually transmitted disease (STD) clinic attenders in Trinidad.
Design and methods: Serial cross-sectional studies were conducted in 1987-1988 and 1990-1991 at a centralized STD clinic in Port of Spain. A case-control study was carried out to examine in greater detail the demographic and behavioral risk factors for HIV-1 among self-declared heterosexuals in this population.
Results: HIV-1 prevalence increased from 3.0% [95% confidence interval (CI), 2.3-3.9] in 1987-1988 to 13.6% (95% CI, 11.8-15.6) in 1990-1991. Age greater than or equal to 40 years [odds ratio (OR), 2.0; 95% CI, 1.4-2.8], urban residence (OR, 2.2; 95% CI, 1.6-3.0), and human T-lymphotropic virus-I seropositivity (OR, 3.1;95% CI, 1.6-6.0) were significant risk factors for HIV-1 in 1990-1991. In the case-control analysis, significant independent risk factors for men included current genital ulcer disease (OR, 5.2; 95% CI, 2.2-12.5), current genital warts (OR, 3.9; 95% CI, 1.2-12.0), having ever had syphilis (OR, 3.2; 95% Cl, 1.6-6.1), and use of crack cocaine in the preceding 6 months (OR, 6.2; 95% CI, 2.7-14.2). Corresponding risk factors for women were commercial sex work (OR, 5.7; 95% CI, 1.3-25.7), initiation of sexual activity before age 14 years (OR, 4.8; 95% CI, 1.5-16.0), and past non-gonococcal cervicitis (OR, 4.1; 95% CI, 1.3-13.1).
Conclusions: HIV-1 in this setting is primarily heterosexually transmitted in a milieu of unprotected sexual activity fuelled by a crack cocaine epidemic. Targeted interventions to prevent, detect and treat STD and crack cocaine addiction, as well as disrupt their adverse synergism, may substantially reduce HIV-1 transmission in this population.

AB RO 15-4513, an inverse agonist at the GABA/benzodiazepine receptor Cl- channel complex, antagonizes multiple effects of ethanol. Prostaglandin synthesis inhibitors, such as indomethacin, also antagonize several effects of alcohols, However, prostaglandin synthesis inhibitors and RO 15-4513 each provide only partial antagonism of ethanol, typically seen as a dose-related effect with a maximum efficacy of similar to 50%. The purpose of this study was to: (i) compare the relative efficacy of these compounds for antagonizing ethanol; (2) compare the effectiveness of preethanol treatment versus postethanol treatment with each drug; and (3) compare the effect of RO 15-4513 and indomethacin in combination with the effects of each drug alone. The results show that indomethacin significantly decreased duration of loss of the righting reflex when administered either pre- or postethanol. Conversely, RO 15-4513 decreased duration of loss of the righting reflex only when given preethanol. When coadministered, RO 15-4513 and indomethacin did not show additive or synergistic effects, Compounds from these two drugs classes should continue to prove useful in elucidating ethanol's mechanisms of action.

AB Fat distribution and metabolic variables were studied in 8 black and 10 white age- and weight-matched obese women undergoing a 6-mo weight-reducing regimen. Fat patterning was determined by using anthropometry and computed tomography to quantitate total, subcutaneous, and visceral adipose tissue (VAT) areas at the L2-L3 and L4-L5 levels of the lumbar spine, before, during, and after a modified fast. Black women had smaller depots of VAT than white women at both the L2-L3 (P = 0.004) and L4-L5 (P = 0.054) sites. Differences persisted after an average 17.2-kg weight loss. Although waist-hip ratio was similar in both groups, black women had 23% less VAT than white women (P = 0.007). Black women had significantly lower plasma glucose (P = 0.031) and triglycerides (P = 0.006) with significantly higher plasma high-density-lipoprotein concentrations (P < 0.001). Data from this study suggest that racial differences exist in VAT and metabolic risk factors for obesity-related illness.

TI LABORATORY EVALUATION OF THE GLUMA 3-STEP BONDING SYSTEM
SO AMERICAN JOURNAL OF DENTISTRY
LA English
DT Article
ID POLYMERIZATION; PRETREATMENT
AB Purpose: To determine in vitro (1) the shear bond strengths (SBS) of the modified Gluma system to enamel and dentin; (2) the qualitative and the quantitative microleakage (ML) of Class V preparations on the cemento-enamel junction (CEJ) and in dentin, respectively, restored with the Gluma system; and (3) the effect of the system's components on enamel and dentin by scanning electron microscopy. Materials and Methods: Seventy-five extracted human maxillary permanent central incisors and 75 permanent first and second molars were embedded in brass tooth cups with cold-cure acrylic resin. The facial surfaces of the anterior and the occlusal surfaces of the molar teeth were ground wet on 180- followed by 600-grit silicon carbide paper. Demarcated sites on the surfaces were treated according to the manufacturer's instructions and Pekafill composite was bonded to the treated surfaces. Fifteen specimens prepared on enamel were removed 1 minute after cure (A) and the SBS determined. The remaining specimens were removed 15 minutes after final cure, stored in saline at 37 degrees C for 24 hours (B), for 1 week without (C) and with temperature cycling (D), and for 4 weeks (E). Similar regimens were used for dentin, groups F, G, H, I and J. The SBS were determined and expressed in MPa. The data were analyzed by ANOVA, Student-Newman-Keuls and t-tests. For the qualitative ML evaluation, Class V cavities were prepared on the CEJ of 30 human premolars and restored with Gluma/Pekafill. After thermocycling in 0.5% basic fuchsin, the teeth were sectioned and ranked according to the degree of microleakage. Class V cavities were prepared on the facial root surfaces of 15 human premolars and restored. The ML was determined quantitatively by a spectrophotometric dye-recovery method and expressed as mu g dye/restoration. Results: The mean +/- SD of the SBS in MPa were: A: 14.6 +/- 2.2; B: 21.2 +/- 1.6; C: 20.5 +/- 1.4; D: 24.2 +/- 2.0; E: 22.8 +/- 3.7; F: 7.0 +/- 2.0 G: 16.1 +/- 4.0; H: 15.6 +/- 3.7; I: 10.9 +/- 3.3; J: 14.4 +/- 3.3. The quantitative ML was 1.00 +/- 0.39 mu g dye/restoration. The lowest SBS were obtained on specimens tested after 1 minute. Temperature cycling had a significantly adverse effect on the SBS to dentin (P=0.0003). Etch patterns conducive to bonding were produced on the enamel. The resin system penetrated into the dentin tubules.

AB The objective was to study changes in the occurrence of human immunodeficiency virus type 1-related Kaposi's sarcoma and the association with degree of immunodeficiency over time. Danish patients with acquired immunodeficiency syndrome (AIDS) diagnosed between 1979 and 1990 (n = 687) were followed clinically and with consecutive CD4 cell count measurement from time of AIDS-defining illness to date of death or censoring date, whichever came first. The proportion of home-/bisexual men (n = 520) with Kaposi's sarcoma (n = 100) at AIDS diagnosis declined from 31% before 1985 to 13% in 1990, whereas the proportion of patients who died with Kaposi's sarcoma remained constant over time. Furthermore, the CD4 cell count at time of AIDS for patients diagnosed with Kaposi's sarcoma has declined in recent years. A CD4 cell count <200 X 106/liter at the time of AIDS diagnosis predicted an increased risk of developing Kaposi's sarcoma after the AIDS diagnosis. Age, antiretroviral therapy, and primary Pneumocystis carinii pneumonia prophylaxis failed to influence the development of Kaposi's sarcoma. Thus, the occurrence of Kaposi's sarcoma remained constant over time but developed later in the course of AIDS and was associated with more severe immunosuppression in recent years.

AB Two patients with macroglobulinemia (monoclonal IgM in the serum) and massive splenomegaly were incapacitated by progressive disease refractory to standard chemotherapy, In each case, palliative splenectomy was followed by a prompt, complete, and unexpected clinical remission with disappearance from the serum of the monoclonal IgM component, One patient remains free of disease 12 years after splenectomy, The other patient remained free of detectable macroglobulinemia for 13 years after splenectomy, A review of the literature revealed other cases of remission of macroglobulinemia attributable to splenectomy alone. Data in humans and animals suggest that the spleen may facilitate IgM secretion by normal and malignant B lymphocytes, Splenectomy should be considered a possible treatment option for patients with massive splenomegaly and macroglobulinemia who progress on chemotherapy.

AB An autosomal recessive deficiency of acid alpha-gIucosidase (GAA), type II glycogenosis, is genetically and clinically heterogeneous. The discovery of an enzyme-inactivating genomic deletion of exon 18 in three unrelated genetic compound patients-two infants and an adult-provided a rare opportunity to analyze the effect of the second mutation in patients who displayed dramatically different phenotypes. A deletion of Lys-903 in one patient and a substitution of Arg for Leu-299 in another resulted in the fatal infantile form. In the adult, a T-to-G base change at position -13 of intron 1 resulted in alternatively spliced transcripts with deletion of exon 2, the location of the start codon. The low level of active enzyme (12% of normal) generated from the leakage of normally spliced mRNA sustained the patient to adult life.

TI ITRACONAZOLE TREATMENT OF DISSEMINATED HISTOPLASMOSIS IN PATIENTS WITH
THE ACQUIRED-IMMUNODEFICIENCY-SYNDROME
SO AMERICAN JOURNAL OF MEDICINE
LA English
DT Article
ID AMPHOTERICIN-B; AIDS; DIAGNOSIS; THERAPY; ANTIGEN
AB PURPOSE: Amphotericin B has been the treatment of choice for disseminated histoplasmosis in patients with acquired immunodeficiency syndrome (AIDS). Oral antifungal agents would be welcome alternatives to standard treatment of disseminated histoplasmosis in less severe cases. The purpose of this study was to assess the efficacy and safety of itraconazole therapy in patients with AIDS and disseminated histoplasmosis.
PATIENTS AND METHODS: This was a multicenter, open-label, nonrandomized prospective trial conducted in university hospitals of the AIDS Clinical Trial Group. All patients had AIDS and first episodes of disseminated histoplasmosis. Patients with central nervous system involvement or with severe clinical manifestations were excluded. Patients were treated with itraconazole BID by mouth 300 mg for 3 days and then 200 mg BID for 12 weeks. Resolution of clinical findings, clearance of positive cultures, and drug tolerance were the main outcome measurements. A secondary objective was effect of therapy on Histoplasma capsulatum var capsulatum antigen levels.
RESULTS: Of 59 evaluable patients, 50 (85%) responded to therapy. Five patients withdrew because of progressive infection, 1 died of a presumed pulmonary embolus within the first week of therapy without improvement, 2 withdrew because of toxicity, and 1 was lost to follow-up after week 2 of therapy. Patients with moderately severe clinical (fever >39.5 degrees C or Karnofsky score <60) or laboratory abnormalities (alkaline phosphatase >5 times normal or albumin <3 g/dL) at baseline tended to respond more poorly than did other patients. Resolution of complaints of fever and improvement in fatigue occurred after a median of 3 and 6 weeks, respectively, and weight gain after 2 weeks. Fungemia cleared after a median of 1 week. H capsulatum var capsulatum antigen cleared from the urine and serum at rates of 0.2 and 0.3 units per week, respectively.
CONCLUSIONS: Itraconazole is safe and effective induction therapy for mild disseminated histoplasmosis in patients with AIDS, offering an alternative to amphotericin B in such cases. Patients with moderately severe or severe histoplasmosis should first be treated with amphotericin B and then may be switched to itraconazole after achieving clinical improvement.

AB A variety of sexually transmitted diseases frequently accompany infection with human papilomavirus and stimulate inflammation of the cervical mucosa. Inflammation and cell injury cause release of proinflammatory cytokines, which in turn might regulate growth of human papillomavirus-infected cells. This study compared the interaction of the proinflammatory cytokine, interleukin-6 (IL-6), and its soluble receptor with normal ecto- and endocervical cells, human papillomavirus-immortalized ectocervical cells, and squamous carcinoma-dervied cell lines. Proliferation of normal cervical cells was enhanced by IL-6 but inhibited by its soluble receptor. However, both IL-6 and its soluble receptor significantly stimulated growth of the three immortal and four cervical carcinoma-derived cell lines analyzed. Stimulation by IL-6 was dose dependent and was blocked by an antibody that neutralized IL-6 activity. IL-6-mediated proliferation was accompanied by increased expression of RNAs encoding transforming growth factor-alpha and amphiregulin, two epidermal growth factor receptor ligands. Furthermore, growth stimulation by IL-6 was significantly inhibited by antibodies that either blocked signal transduction by the epidermal growth factor receptor or that neutralized transforming growth factor-alpha or amphiregulin activity. Thus, IL-6 stimulates proliferation of human papillomavirus-immortalized cervical cells via an epidermal growth factor receptor-dependent pathway involving autocrine stimulation by transforming growth factor factor-alpha and amphiregulin.

AB Rates of valine incorporation into protein were measured under control and valine-''flooding'' conditions and included correction for the degree of recycling of unlabeled valine derived from the steady-state breakdown of tissue protein into the precursor pool (tRNA bound). The correction factor lambda, which is the ratio of the steady-state specific activity of valine in the tissue tRNA-bound pool to that in the arterial plasma, was determined for each of the tissues. In controls, values of lambda ranged from 0.31 in adrenals to 0.54 in heart; in flooded animals, values were higher, but only in liver was the value of lambda close to 1.0. In control and flooded rats, rates of protein synthesis were highest in liver and adrenals and lowest in skeletal muscle, with intermediate values in brain and heart. Flooding resulted in increased rates of protein synthesis in liver and decreased rates in adrenals. Rates of protein synthesis in brain, heart, and skeletal muscle were not statistically significantly affected by flooding.

AB Functional studies suggest that guinea pig chief cells have both cholecystokinin-A (CCK-A) and CCK-B receptors (CCK-A-R and CCK-B-R, respectively). However, all efforts to directly characterize the specific CCK-A-R using binding have been unsuccessful. Recent studies describe specific CCK-A-R agonists such as A-71378 {[desamino-Nle(28,31)-(N-methyl)Asp(32)]CCK heptapeptide}. In the present study, [D-Tyr-Gly]A-71378 was synthesized, which has > 300-fold selectivity for CCK-A-R and can be iodinated. [D-Tyr-Gly]A-71378 was equipotent to A-71378 in stimulating pepsinogen release from purified guinea pig chief cells. Binding of I-125-labeled [D-Tyr-Gly]A-71378 was saturable and specific, Potencies for inhibiting binding were as follows: [D-Tyr-Gly]A-71378 = A-71378 = 4 x CCK octapeptide (CCK-8) > 1,000 x des(SO4)CCK-8, gastrin. In contrast, for I-125-gastrin binding they were CCK-8 > gastrin-17-I > des(SO4)-CCK-8 >> A-71378 or [n-Tyr-Gly]A-71378. Binding of [D-Tyr-Gly]A-71378 was best fitted by a two-site model. In contrast, I-125-gastrin binding was fitted with a single-site model. For inhibiting binding of I-125-[D-TyrGly]A-71378, the CCK antagonists had relative affinities of L-364,718 >> L-365,260, and the reverse was true with I-125-gastrin. Correlation of binding with changes in biological activity suggested low-affinity CCK-A-R were mediating these changes. These results demonstrate directly for the first time that guinea pig chief cells possess CCK-A-R and CCK-B-R. The pharmacology of these CCK-A-R resembles those on other tissues. This novel, highly selective CCK-A ligand should be useful because it will identify CCK-A-R when they make up as little as 0.2% of the total CCK receptor number.

AB We studied the differential hemodynamic effects of N-omega-monomethyl-L-arginine (L-NMMA), an inhibitor of nitric oxide (NO) synthesis, in normal and endotoxemic dogs and examined its activity across the venous, pulmonary, and systemic circulations. Survival was used to determine therapeutic efficacy. In both normal and endotoxemic animals, L-NMMA similarly increased systemic (P = 0.01) and pulmonary (P = 0.047) vascular resistance, marginally increased mean arterial pressure (P = 0.07), and decreased oxygen delivery (P = 0.01) compared with normal saline. In contrast, the effect of L-NMMA on mean pulmonary arterial pressure, central venous pressure, and pulmonary capillary wedge pressure was different in endotoxemic than in normal animals (P < 0.05), but this differential effect occurred >6 h after endotoxin challenge. L-NMMA (1-10 mg . kg(-1). h(-1)) did not significantly increase survival rates or times in endotoxemic animals, but the highest dose decreased survival times (P < 0.05). Thus the effect of L-NMMA was similar on the systemic arterial circulation in endotoxemic dogs compared with normal dogs but was increased in the venous and pulmonary vascular beds after endotoxin, suggesting that the induction of NO production was greater in low-resistance vessels. We were unable to show that nonselective inhibition of NO production was beneficial in endotoxemic dogs.

AB The CC10 gene encodes the Clara cell 10-kDa protein, which is expressed in airway epithelial cells. Quantification of CC10 gene expression in freshly isolated human proximal airway epithelial cells demonstrated very high mRNA levels, approximately fivefold greater than gamma-actin mRNA, and in situ hybridization localized CC10 mRNA to nonciliated airway epithelial cells. Sequence analysis demonstrated that the human CC10 gene is comprised of three short exons separated by a long first and short second intron, and with a 5' flanking region typical of a regulated gene. Three Alu repeats were observed in intron 1 and one in intron 2. Two polymorphic regions within the introns were identified. First, a microsatellite was localized 5' to the third Alu repeat in intron 1 with a variable number of 4- and 5-base pair (bp) repeats and a heterozygosity of 0.71. Second, in 3% of the 168 chromosomes examined, there was the insertion of a human-specific Alu repeat in intron 2, 45 bp 3' to the exon 2-intron junction. In three Centre d'Etude du Polymorphisme Humain families, meiotic breakpoint analysis using these two polymerphic loci localized the CC10 gene to 11 p12-q13 between markers D11S16 and D11S97, a region recently linked to atopy and to the beta-subunit of the high-affinity immunoglobulin E receptor. The observations in the present study of high-level expression of the CC10 gene in the epithelium of conducting airways and a subchromosomal localization of the gene to a region potentially linked to inflammatory airway disease, together with the reported anti-inflammatory and immune-modulating properties of the protein, suggest the CC10 gene product may be important in modulating inflammation within the airways. If so, the highly heterozygous microsatellite described in the present study should facilitate analysis of a possible linkage of the CC10 gene with an inherited susceptibility to asthma.

AB Objectives. Worldwide declines in the duration of lactation are cause for public health concern. Higher levels of dichlorodiphenyl dichloroethene (DDE) have been associated with shorter durations of lactation in the United States. This study examined whether this relationship would hold in an agricultural town in northern Mexico.
Methods. Two hundred twenty-nine women were followed every 2 months from childbirth until weaning or until the child reached 18 months of age. DDE was measured in breast milk samples taken at birth, and women were followed to see how long they lactated.
Results. Median duration was 7.5 months in the lowest DDE group and 3 months in the highest. The effect was confined to those who had lactated previously, and it persisted after statistical adjustment for other factors. These results are not due to overtly sick children being weaned earlier. Previous lactation lowers DDE levels, which produces an artifactual association, but simulations using best estimates show that an effect as large as that found here would arise through this mechanism only 6% of the time.
Conclusions. DDE may affect women's ability to lactate. This exposure map be contributing to lactation failure throughout the world.

AB alpha 1-Antitrypsin (alpha AT) deficiency, a hereditary cause of progressive emphysema, can potentially be treated by transfer of a functional human alpha 1AT gene to the respiratory epithelium. For such an approach to be successful, alpha 1AT must be provided to both the interstitium and the epithelial surface-that is, the alpha 1AT directed by the transferred gene must be secreted to both the apical and basolateral surfaces of the epithelial cells. To evaluate this concept, a recombinant, replication-deficient adenoviral vector (Ad-alpha 1AT) containing a human alpha 1AT cDNA driven by an adenovirus major late promoter was used to infect Bet-1A human respiratory epithelial cells. The infected cells expressed Ad-alpha 1AT-directed mRNA transcripts and synthesized and secreted functional human alpha 1AT as shown by [S-35]methionine labeling and immunoprecipitation of a 52-kD glycosylated human alpha 1AT molecule capable of interacting with neutrophil elastase, its natural substrate. Bet-1A cells grown on microporous polycarbonate membranes formed tight junctions (resistance > 150 Ohm x cm(2)). After infection with Ad-alpha 1AT, [S-35]methionine labeling and enzyme-linked immunoassay demonstrated that alpha 1AT was secreted into both the apical and basolateral compartments, with an average apical to basolateral ratio of 1.9 +/- 0.2. Thus, human respiratory epithelial cells infected with a recombinant adenoviral vector containing a human alpha 1AT cDNA secrete alpha 1AT across both the apical and basolateral cell membranes, suggesting that the respiratory epithelium could serve as a target for in vivo gene therapy of alpha 1AT deficiency.

AB In this report we described the establishment and characterization of a continuous rat tracheal epithelial (RTE) cell line spontaneously derived from secondary RTE cell cultures. Designated SPOC1, this cell line is nontumorigenic and maintains a diploid karyotype with specific, nonrandom chromosomal alterations involving chromosomes 1, 3, and 6. SPOC1 cells demonstrate decreased requirements for peptide growth factors, compared with primary RTE cells. Upon inoculation into denuded rat tracheas, which are then implanted into syngeneic hosts, SPOC1 cells initially form a stratified squamous epithelium, which becomes less stratified with time and forms glandlike invaginations into the surrounding lamina propria. No evidence of ciliated cell differentiation is detected. The epithelium formed by SPOC1 cells in tracheal grafts reacts with antibodies specific for keratin 14, 13, and 19 (but not keratin 18) at both early and late time points, although the localization of antibody staining changes as the epithelium becomes less stratified with time. The suprabasal epithelial cells become positive for alcian blue-periodic acid-Schiff staining at later time points. The near-normal karyotype and differentiation potential of SPOC1 cells make this cell line a unique window into early changes occurring during immortalization of airway epithelial cells and will allow studies of relationships between differentiation state and neoplastic transformation.

AB Men have significantly more atherosclerotic disease than women. Platelet-mediated thrombosis plays a role in the initiation of myocardial infarction and stroke. Citrated whole blood from male and female donors was perfused through an annular system over everted human umbilical artery segments. Comparisons were made between platelet adherence and thrombus formation on subendothelium, platelet aggregation in citrated whole blood, hematologic variables, and the bleeding time. Platelet spreading and adherence were approximately 22% greater with male blood (P < 0.001), whereas thrombus formation on subendothelium and collagen- and arachidonic acid-induced platelet aggregation did not show sex-related differences. Platelet aggregation with adenosine diphosphate was greater in women, related to their lower hematocrit values. By contrast, in women hematocrit values showed a slight but significant positive correlation with platelet adherence on subendothelium. Fibrinogen was significantly correlated with collagen- and adenosine-diphosphate-induced platelet aggregation and with platelet adherence, spreading, and thrombus formation on subendothelium. The mean bleeding time was slightly longer in women than in men (P = 0.118). Platelet aggregation was not associated with the bleeding time except for collagen-induced platelet aggregation in males; the latter was significantly correlated with platelet adherence and spreading in both sexes, while arachidonic acid-induced platelet aggregation predicted platelet adherence and spreading in males. Male blood shows enhanced primary hemostatic activity; this may predispose men to atherosclerosis.

AB Cytomegalovirus (CMV) commonly infects both normal and immunocompromised hosts. Although it usually produces an asymptomatic infection to mild illness, CMV has the potential to significantly injure many different organs. Reports of CMV causing pericardial disease, however, are limited and documentation of infection by growth of the virus from tissue or fluid is rare. As part of a prospective trial of subxiphoid pericardial biopsy in 57 adult patients with large pericardial effusions, three culture-proven cases and one serologically confirmed case of CMV pericardial disease were discovered. Subsequently, CMV was grown from the pericardium of an infant with congenital heart disease. A review of the documented cases of CMV pericarditis is provided along with a discussion of the pathogenesis and significance of this perhaps not so uncommon disease.

TI ON POLITICS AND HEALTH - AN EPIDEMIC OF NEUROLOGIC DISEASE IN CUBA
SO ANNALS OF INTERNAL MEDICINE
LA English
DT Editorial Material
AB Political decisions may cause disease. During 1992 and 1993, an epidemic of neuropathy in Cuba-largely overlooked by U.S. physicians-affected more than 50 000 persons and caused optic neuropathy, deafness, myelopathy, and sensory neuropathy. Patients with the neurologic disease responded to B group vitamins, and oral vitamin supplementation of the population curbed the epidemic. Dietary restrictions and excessive carbohydrate intake were the immediate cause of the epidemic; however, the primary cause might have been political. Political changes in eastern Europe had major repercussions on Cuba's economy and food supply. In turn, these changes compounded the effects of internal political decisions in the island, leading toward isolationism and economic dependence on the former Soviet Union. Also, for more than 30 years, the United States has maintained an economic embargo against Cuba. In 1992, the U.S. embargo was tightened by the Torricelli amendment (or the Cuba Democracy Act), which prohibited third-country subsidiaries of U.S. companies from trading with Cuba and prevented food and medicines from reaching the island; this amendment produced a virtual economic blockade. Penuries resulting from all these political events resulted in the largest epidemic of neurologic disease in this century. Physicians may need to use their influence to modify political decisions when these decisions result in adverse health consequences. The American Academy of Neurology has issued a plea to encourage physicians and other health personnel to support efforts leading to lifting of the U.S. embargo against Cuba for humanitarian reasons.

AB Recent experimental and clinical research has demonstrated that opioids can produce potent and receptor-specific analgesic effects outside the central nervous system. Opioid receptors are localized on peripheral terminals of sensory nerves and their endogenous ligands, opioid peptides, have been discovered in immune cells within inflamed tissue. Many controlled clinical studies confirm the experimental data. These findings open up the exciting perspective of the development of an entirely novel generation of peripherally active opioid analgesics devoid of centrally mediated side effects.

AB This report characterizes nine new cell lines derived from patients with malignant pleural mesothelioma. The lines were initiated between July 1990 and July 1992 from solid tumors (5 lines) or effusions (4 lines) and had proliferated for a period of at least 2 months without senescence. They were characterized by cell size, doubling time, immunohistochemical analyses, electron microscopy, and chromosomal karyotyping. Growth factor/cytokine elaboration was determined using enzyme-linked immunoassays. The established lines were similar in morphology to their parent tumor (ie, epithelial or sarcomatoid). Cell sizes ranged from 59 to 81 mu m, and the doubling times varied from 31 to 65 hours. The lines stained with cytokeratin and showed expected negative staining for adenomarkers including B72.3 and carcinoembryonic antigen. All cell lines exhibited aneuploidy, with modal chromosome numbers between 40 and 81 and had multiple chromosomal aberrations. Significant production of granulocyte-monocyte colony-stimulating factor, leukemia inhibitory factor, platelet-derived growth factor, and interleukin-6 was seen. These new cell lines derived from human mesotheliomas can now be used to aid in the design of innovative treatment strategies.

AB Owing to its sparingly soluble properties, the potential anticancer drug pancratistatin (1) resisted conventional drug formulation procedures and the synthesis of a water-soluble prodrug became necessary. That important objective for further pre-clinical development was met by devising a route to a disodium phosphate derivative (5). The key step in the synthesis of the phenolic phosphate was phosphorylation of 1,2,3,4-tetraacetoxy-pancratistatin (2) with dibenzyloxy(N,N-diisopropylamido)phosphine. Subsequent oxidation with m-chloroperbenzoic acid afforded phosphate 4a. Hydrogenolysis of the benzyl esters followed by base-catalysed hydrolysis of the acetate groups led to the water-soluble prodrug 5 in high yield.

AB Cidofovir {HPMPC; (S)-1-[3-hydroxy-2-(phosphonylmethoxy)propyl]cytosine} is a nucleotide analog with activity against human (CMV). A phase I/II dose escalation trial was conducted with asymptomatic human immunodeficiency virus (HIV)-infected patients with CMV viruria to determine its pharmacokinetics, maximally tolerated dose, and preliminary antiviral activity against CMV. Qualitative CMV blood and urine cultures were monitored weekly to assess anti-CMV activity. Twenty-one HIV-infected persons with CD4 counts from 0 to 389 cells per mu l (median, 39) were enrolled in six dose-ranging groups. The first five groups enrolled four patients each to receive cidofovir infusions either weekly or biweekly for 4 weeks or every 3 weeks for 12 weeks. The sixth group enrolled one patient who received infusions of 5 mg/kg of body weight every other week. Patients receiving 0.5 or 1.5 mg/kg twice weekly experienced no serious toxicity. The first two patients who received 5 mg/kg twice weekly developed glycosuria and 2+ proteinuria. Subsequent patients received concomitant probenecid to attempt to ameliorate renal toxicity. Seventeen patients experienced proteinuria on one or more occasions; 6 of them experienced at least 2+ proteinuria. Four patients did not complete the study as planned because of renal toxicity. Positive CMV urine cultures reverted to negative in 2 of 8 patients receiving doses of less than or equal to 1.5 mg/kg twice weekly and 11 of 13 patients receiving higher doses. Cidofovir has in vivo anti-CMV activity demonstrated by prolonged clearing of CMV viruria, although this observation is tempered by the fact that clearance of viremia could not be demonstrated. The dose-limiting toxicity is renal; however, concurrent administration of probenecid may be protective. The maximally tolerated weekly intravenous dose with probenecid is approximately 5 mg/kg. Efficacy trials with CMV disease will define the therapeutic utility and optimal dosing interval for cidofovir.

TI HIGH-YIELD PRODUCTION OF DIPHTHERIA-TOXIN MUTANTS BY HIGH-DENSITY
CULTURE OF C7(BETA)(TOX+) STRAINS GROWN IN A NON-DEFERRATED MEDIUM
SO APPLIED MICROBIOLOGY AND BIOTECHNOLOGY
LA English
DT Article
ID CORYNEBACTERIUM-DIPHTHERIAE; BETA; MUTATIONS
AB A high-density growth approach was utilized to produce mutated diphtheria toxin from two strains of Corynebacterium diphtheria: C7 (beta)((tox-201, tox-9)) and C7 (beta)((tox-107)). The cross-reacting mutants (CRM) of the diphtheria toxin are CRM9 and CRM107; both of them carry the mutation in their binding site and, as a result, have 1/300 of the systemic toxicity of the wild-type diptheria toxin. Since iron inhibits diphtheria toxin production, the traditional approach has been to grow the bacteria in a very low iron concentration. The procedure described here involved the use of a modified, non-deferrated, growth medium that provided fast and high-density growth of the bacteria, and which, when associated with simultaneous depletion of glucose and iron, enhanced the toxin production. Oxygen-enriched air was supplied to enable the bacteria to grow to a cell density giving an absorbance of 70 at 600 nm (15-20 g/l dry weight). The maximum toxin concentration in the culture supernatant was 150 mg/l. The CRM products, which remained stable following microfiltration and ultrafiltration, could be easily purified using a two-step chromatography procedure.

AB Extreme halophilic archaea are saturated with salt and the intracellular electrolyte concentration exceeds that of the extracellular environment. Enzymes and other proteins from extreme halophilic archaea have been purified for many years and studied by biochemical and biophysical solution methodologies. They are active and stable at multimolar salt concentrations and denature below 2 to 3 M NaCl or KCl, Adaptation to these high concentrations of salt, genetic and evolutionary aspects, and the possibility of biotechnological applications are problems of considerable interest, Since the status of this fascinating field of research was reviewed in 1992, malate dehydrogenase from Haloarcula marismortui, now known to be a tetramer, was sequenced, its gene was cloned and expressed in active form, and its physical properties were redefined, A single mutation of Arg(100) (in the enzyme active site) to Gin switched the enzyme specificity from malate to lactate dehydrogenase, Recent determination of its molecular structure by X-ray crystallography (O, Dym ct al., in press) provides an exciting basis for the understanding of the structure and function of extreme halophilic enzymes, A major problem which so far has not been tackled in the study of extreme halophilic archaea is the understanding of protein nucleic acid interactions which are essential for the performance of biological function, Whereas the stability and activity of enzymes and other proteins can be modified to perform at high salt concentrations by use of currently known structural concepts, the existence of meaningful protein nucleic acid interactions in physiological concentrations of 4 to 5 M KCI constitutes an unsolved enigma worth intensive investigation.

AB The thermal unfolding of monomeric Acanthamoeba myosin II and rabbit skeletal muscle myosin at pH 7.5 in 0.6 M KCl has been studied by differential scanning calorimetry (DSC) and circular dichroism, A single endotherm (at similar to 40 to 45 degrees C) with a maximum at 41.7 +/- 0.1 degrees C and Delta H approximate to 1080 +/- 180 kcal/mol is observed for both dephospho- and phospho-myosin II, Skeletal muscle myosin unfolds with less cooperativity over a wider temperature range (similar to 40 to 60 degrees C) with Delta H approximate to 2500 kcal/mol, The thermal unfolding of either myosin results in a loss of similar to 70% of a-helical structures, Saturation of dephospho- or phospho-myosin II with 5'-adenylylimidodiphosphate (AMPPNP) in the presence of Mg2+ produces a second endotherm with a maximum at similar to 49 degrees C, The latter observation is attributed to a stabilization of head regions by nucleotide binding, Indeed, a purified N-terminal myosin II head fragment has been found to unfold with T-max similar to 41 and similar to 48 degrees C in the absence and presence of AMPPNP, respectively, The stabilization of the head regions is less with ADP + P-i and still smaller with ADP alone, In summary, thermally induced unfolding of myosin II is affected by nucleotide binding to heads, but not by phosphorylation or even removal of a 66-amino-acid tailpiece containing phosphorylation sites, The observed differences in the cooperativity of unfolding myosin II and skeletal muscle myosin relate to differences between rod structures and possibly also head-rod interactions.

AB The aim of this work was to get some insight into the mechanism by which ACTH produces its enhancing effect on glucose-induced insulin secretion. For this purpose, we have determined: a) the release of insulin by isolated rat islets incubated with 3.3 or 16.6 mM glucose with or without the addition of 500 pg/ml ACTH, together with the changes induced by ACTH on b) cytosolic [Ca2+] of isolated B cells, c) islet plasma membrane Ca2+-ATPase activity and d) changes in membrane potential of single mouse islets.
ACTH significantly enhanced the release of insulin elicited by either 3.3 or 16.6 mM glucose. This hormone concentratian also induced a significant increase in the cytosolic [Ca2+] in isolated B cells. ACTH did riot produce B cell membrane depolarization. Conversely, ACTH produced a significant decrease in islet plasma membrane Ca2+-ATPase activity.
These results suggest that ACTH in concentrations similar to those attained by the endogenous peptide at the islet interstitium exerts its positive modulation on glucose-induced secretion of insulin, at least partly through its increasing effect oil cytosolic [Ca2+] of B cells. The latter might be the consequence of the decreasing effect of ACTH on Ca2+ -ATPase activity rather than to stimulation of voltage-dependent Ca2+-channels.

AB Rhesus monkeys with neonatal damage to either the medial temporal lobe or the inferior temporal cortical area TE, and their normal controls, were reassessed in visual habit formation (24-hour intertrial interval task) and visual recognition (delayed nonmatching to sample; DNMS) at 4-5 years of age and then tested on tactile and spatial DNMS. Results on the two visual tasks were the same as those obtained when the monkeys were under 1 year of age. Specifically, early medial temporal lesions, like late lesions, left habit formation intact but severely impaired recognition memory. Furthermore, the memory deficit extended to the tactile and spatial modalities. By contrast, early damage to TE, unlike late damage to it, yielded only mild deficits on both visual tasks and had no effect on tactile or spatial DNMS. Compensatory mechanisms that promote substantial and permanent recovery thus appear to be available after neonatal TE lesions but not after neonatal medial temporal lesions.

AB There is a significant degree of individual variability in response to drugs of abuse. A goal of behavior genetic studies has been to determine the extent to which observed heterogeneity in drug use can be attributed to genetic and environmental factors and to identify the neurobiological factors involved in vulnerability. Recent hypotheses regarding the predictive value of spontaneous locomotor activity in the acquisition of drug-reinforced behavior are amenable to testing using a behavior genetics approach. Genetic differences in locomotor response to a novel environment were determined in naive and catheterized Lewis, F344, NBR and ACI rats. Operant drug-reinforced behavior was examined in a 23 h access paradigm in which each lever press by a rat produced a 1 mg/kg injection of morphine with a 30 s timeout period (FR 1:TO 30''). Acquisition (7 days), extinction (6 days) and reacquisition (7 days) of morphine self-administration behavior was investigated in all four inbred strains. Large genetic differences in the rate of acquisition and extinction of morphine self-administration were found. Lewis rats responded at high rates beginning in the first two days, whereas F344 rats initially responded at low rates and responding increased gradually over seven days. NBR and ACI rats responded at intermediate levels. When vehicle was substituted for drug there was a significant effect of genotype on the rate of extinction; F344 and ACI increased responding to greater than 175% of drug-response levels, whereas the Lewis response rate decreased gradually and NBR response rate decreased immediately during the first several days. When drug was available again, rates of reacquisition did not differ from original acquisition rates. Drug maintained significantly greater amounts of behavior than vehicle in the Lewis, F344 and NBR rats and was thus shown to serve as a positive reinforcer in these three strains under these conditions. There was a significant genetic correlation among strains between drug intake during the first five days of acquisition and spontaneous locomotor response to a novel environment in catheterized rats. Only the ACI rats showed a significant within-strain correlation. The positive relationship between rate of acquisition of self-administration behavior and locomotor activity suggests that these two traits are influenced by common or closely linked genes. To this end, the neurobiological substrates that mediate spontaneous locomotor behavior under these environmental conditions may act, in part, as a template for determining the neurobiological substrates that mediate the relative rate of acquisition of morphine-taking behavior under these conditions.

AB Ifenprodil, like cocaine, binds to the dopamine transporter and blocks uptake of dopamine. In this study, the ability of ifenprodil to mimic, enhance or block behavioral and toxic effects of cocaine was evaluated. Fixed-interval responding maintained by food presentation In rats was increased by cocaine but decreased by ifenprodil. Low rates of responding during timeout periods were also increased by cocaine but not ifenprodil. Ifenprodil neither increased locomotor activity nor augmented the stimulatory effect of cocaine; however, ifenprodil attenuated the stimulant effects of cocaine at doses 0.5 log unit lower than those required to reduce spontaneous activity when given alone. Ifenprodil neither substituted for nor augmented the discriminative stimulus effects of cocaine in rats discriminating 10 mg/kg cocaine from saline. In contrast to cocaine, ifenprodil did not produce convulsions or signs of proconvulsant activity, and ifenprodil reduced the percentage of mice convulsing in the presence of cocaine. These results suggest that pharmacological actions in addition to blockade of dopamine uptake or novel interactions with the dopamine transporter may contribute to the non-stimulant behavioral profile and cocaine-blocking actions of ifenprodil.

AB It was previously shown that amino acids 609-613 (REDLK) at the C-terminus of Pseudomonas exotoxin (PE) are necessary for cytotoxicity, presumably by directing the toxin to the endoplasmic reticulum (ER) [Chaudhary, Jinno, FitzGerald and Pastan (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 308-312]. Using the anti-[interleukin 2 receptor (IL2R)] immunotoxin anti-Tac(Fv)PE38 (AT-PE38REDLK), it was found that removing the terminal lysine did not alter the activity, but replacing REDL with KDEL, the most common ER retention sequence, increased activity. To determine which amino acid in KDEL was responsible for the increase in activity, we tested eight C-terminal mutants of AT-PE38REDLK. Using IL2R-bearing MT-1 cells, we found that the glutamate residue of KDEL was required for high activity, as the cytotoxicity of AT-PE38 ending in KDEL, RDEL, KEEL or REEL was much greater than that of AT-PE38 ending in REDL, KEDL, RDDL or KDDL. Using freshly isolated lymphocytic leukaemia cells, AT-PE38 ending in KDEL, REEL or RDEL was more than 100-fold more cytotoxic than AT-PE38 ending in KEDL, REDL, RDDL or the native sequence REDLK. The RDEL sequence also improved the cytotoxic activity of an interleukin 4-PE38 toxin fusion protein. Improved cytotoxic activity correlated with improved binding of the C-termini to the KDEL receptor on rat Golgi membranes. These data indicate that the glutamate residue of KDEL improves the cytotoxicity of PE by increasing binding to a sorting receptor which transports the toxin from the transrecticular Golgi apparatus to the ER, where it is translocated to the cytosol and inhibits protein synthesis.

AB An improved assay for hyaluronic acid (HA) synthetase is described that is suitable for rapid processing of large numbers of samples. High background levels of unincorporated radioactivity are removed by passage of the reaction through a Sephadex G-50 spin column. The labeled HA product is then precipitated onto glass fiber filters with cetylpyridinium chloride. Apparent Km values for HA synthetase from Swiss 3T3 fibroblasts are 10.8 and 58.4 mu M for UDP-glucuronic acid and UDP-N-acetylglucosamine, respectively. HA synthetase activity of quiescent cells is 4.5% of that found in actively growing cells and is stimulated in response to 10% calf serum. There is a greater than 10-fold increase in HA synthetase activity when cells are harvested with hyaluronidase as compared with trypsin.

AB Flexible molecules change their conformation upon binding to a protein. This was shown by the analysis of small molecules whose structures have been determined by X-ray crystallography of both the pure compound and the compound bound to a protein. Thirty-three compounds present both in the Cambridge Structural Database and the Brookhaven Protein Data Bank were analyzed, and both were compared with the global energy minimum conformation calculated by the molecular mechanics program CHARMm. It was found that the conformation bound to the protein differs from that in the crystal structure and also from that of the global energy minimum, and the degree of deformation depends upon the number of freely rotatable bonds in the molecule. Analysis of the conformational energies of the flexible molecules showed that, for most of those compounds, both the crystal and the protein-bound conformations are energetically well above the global minimum, and, in many cases, not even in any local energy minimum. Semi-empirical calculations performed for a select number of structures, using both the AM1 and PM3 hamiltonians, confirmed these results. These findings are discussed as to their impact upon contemporary methods of drug design.

SO BIOPHYSICAL JOURNAL
LA English
DT Article
AB The effect of weak, nonspecific interaction between molecules confined within restricted elements of volume (''pores'') and the boundary surfaces of the pore, upon the reactivity and physical state of the confined molecules, is explored by means of simple models. A confined molecule is represented by a rectangular parallelopiped having one of six orientations aligned with the cartesian coordinate axes, and the confining volume element is represented by a pair of parallel surfaces (planar pore), a tube of square cross section (square pore), or a cubical box (cubical pore). Weak interactions are modeled by square-well potentials having a defined range and well depth. Partition coefficients for distribution of molecules between the bulk and confined phase are calculated using an extension of the statistical-thermodynamic theory of Giddings et al. (1968). It is calculated that surface attraction with a potential of only a few kcal/mol monomer may result in large increases in the extent of self- or heteroassociation of confined molecules (as much as several orders of magnitude in favorable cases) linked to adsorption of the oligomeric species onto boundary surfaces. Calculations are also presented suggesting that surface attraction can lead to deformation of the native structure of adsorbed macromolecules. It is suggested that these findings are relevant to an understanding of the structure of eukaryotic cytoplasm.

AB A new method, based on a space-fixed rotation axis, or local helix axis, is proposed for the calculation of the relative orientation variables for a sequence of base pairs. With this method, orientation variables are determined through the rotation of a base pair about this axis. These variables uniquely determine a set of helical variables, similar to the roll, tilt, and twist, commonly used for a description of spatial orientations of internally rigid base pairs. The proposed identification of roll and tilt with the direction cosines of the space-fixed rotation axis agrees well with their customary definitions as the openings of the angles between adjoining base pairs toward the minor groove and toward the ascending (5' to 3') backbone strand, respectively. These new variables permit a more direct physical comprehension of DNA conformations and also the behavior of self-complementary sequences. These direction cosines, together with the rotation angle about the space-fixed axis, form a set of three independent orientation variables of the bases that afford some advantages over the variously defined twist, roll, and tilt angles, either for static or average forms. An example for the static form of these variables is shown through their use to interpret crystal coordinates. An example for the average of orientation variables is based on statistical calculations. In this example, the orientation variables, together with the translational variables that describe the relative displacements of a pair of adjacent base pairs, form a canonically distributed ensemble in phase space spanned by these variables. Two sets of conformational variables are generated by using two different methods for performing rotation operations on the sequences of base pairs. The first method is based on the new single rotation about a space-fixed axis of rotation. This space-fixed axis of rotation is, in fact, the local helicai axis as constructed previously by others. The second method is based on three consecutive rotations by Euler angles. Because of large flexibilities and anisotropies along various conformational variables of DNA base pairs, the two sets of generated conformational variables, based on these two different methods of performing rotation operations, lead to slightly different sets of structurally different, but energetically equivalent, spatial arrangements of the base pairs.

AB The binding of a netropsin analogue to random sequence DNA monitored by CD, is seen dependent on the concentration of neutral solutes. The binding free energy decreases linearly with solute osmolal concentration and the magnitude of the effect is insensitive to the chemical identity of the solute for betaine, sorbitol, and triethylene glycol. These solutes appear to modulate binding through their effect on water activity and changes in the hydration of the drug and DNA in the complex reaction, not through a direct interaction with the reactants or the product. The dependence of binding constant on solute concentration can be interpreted as an additional binding of some 50-60 extra solute excluding water molecules by the complex. A water sensitivity of drug binding is further seen from the dependence of binding constants on the type of anion in solution. Anions in the Hofmeister series strongly affect bulk water free energies and entropies. The differences in netropsin analogue binding to DNA with Cl-, F-, and ClO4- are consistent with the effect observed with neutral solutes. The ability to measure changes in water binding associated with a specific DNA interaction is a first step toward correlating changes in hydration with the strength and specificity of binding.

AB The brain regions controlling self-paced sequential finger movements in patients with cerebellar degeneration were studied by measuring changes in regional cerebral blood flow (rCBF) in eight patients using bolus injections of (H2O)-O-15 and PET The results were compared with those obtained in eight normal age-matched control subjects. Patients and control subjects performed a self-paced sequential finger opposition task with the right hand, completing a sequence of movements every 4-6 s. Both groups had strong increases in the adjusted rCBF contralaterally in the primary motor cortex (M1) and ventral premotor area (PMv), in the caudal supplementary motor area (SMA) and cingulate motor area (CMA), and bilaterally in the prefrontal cortex (PFC), the lobus parietalis inferior (LPI), putamen and cerebellum. The cerebellum, PMv, rostral CMA, PFC and LPI were move active in the control subjects than in the patients, and the M1, SMA, caudal CMA and putamen were more active in the patients than in the control subjects. The reduced activity of the cerebellar neurons in the patients produced a complex pattern of rCBF increases and decreases in other brain regions. Our results suggest that for the preparation and execution of sequential finger movements, patients with cerebellar degeneration use a medial premotor system, including the SMA and caudal CMA, as well as the MI and putamen, rather than the PMv, PFC, LPI and rostral CMA.

AB After a decade of intensive clinical and molecular genetic efforts the von Hippel-Lindau (VHL) gene was cloned in 1993. The open reading frame encodes the putative protein of 284 amino acids. A large number of different mutations have been identified so far, including single base mutations, deletions, rearrangements and more complex mutations. So far, in about 75% of the VHL families germline mutations were detected. Geno-phenotypic comparision has revealed specific mutations with distinct manifestation patterns. Not all of the 6 classical lesions (hemangioblastoma of the CNS, retinal angiomatosis, pancreatic cysts, renal cysts and carcinoma, pheochromocytoma and epididymal cystadenoma) are present in VHL families. Pedigrees with pheochromocytoma but without renal cancer in general have point mutations. These recent results provide insight in the pathogenesis of a multiorgan cancer susceptibility tumor suppressor gene and allow determination of carrier status.

AB Human liver carcinoma cells (BEL-7404) and human KB adenocarcinoma cells were selected by stepwise increases in cisplatin. Drug sensitivity assays indicated that the IC50 value for 7404-CP7.5 cells was 49 mu g ml(-1) cisplatin, 111-fold higher than for the parental hepatoma cells. The IC50 value for KB-CP10 cells was 38 pg ml(-1) cisplatin, which is 1152-fold higher than for the parental KB cells. The 7404-CP7.5 cells were cross-resistant to methotrexate (39 x), 5-fluorouracil (23 x) and 6-mercaptopurine (13 x), but were sensitive to drugs which are known substrates for the multidrug transporter (P-glycoprotein), including colchicine, vinblastine and actinomycin D. Similar cross-resistance patterns were observed for KB-CP10 cells. No evidence of DNA amplification or expression of the MDR1 gene was found. One-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis showed increases in 52 kDa protein(s) in both the soluble cytosolic and crude membrane fractions in 7404-CPr cells and in KB-CPr cells. The amount of 52 kDa protein was proportional to the degree of resistance of the 7404-CPr cells to cisplatin. Two-dimensional gel analysis demonstrated that two polypeptides of molecular mass 52 and 50 kDa were overexpressed in the membrane fractions in both 7404-CP20 and KB-CP20 cells. Using amino acid microsequencing and Western blotting, the major 52 kDa protein was identified as the mitochondrial heat shock protein hsp60. Two-dimensional gels of [S-35]methionine-labelled polypeptides showed many other changes, including reduction in soluble proteins of approximately 57 kDa molecular weight in KB-CP20 cells, and of 35 kDa in both 7404-CP20 and KB-CP20 cells. These results suggest that alterations of certain proteins occur commonly in cisplatin-resistant cells, particularly proteins of molecular weight 52 and 50 kDa.

AB Preincubation of etoposide-resistant human MCF7 breast cancer cells (MCF7/VP) with buthionine sulphoximine (BSO) resulted in their sensitisation to etoposide and vincristine. Chemosensitisation was accompanied by elevated intracellular drug levels. In contrast, simultaneous exposure to BSO did not result in increased drug accumulation. Similar, but quantitatively smaller, effects were also observed when sensitive wild-type MCF7/WT cells were treated with BSO. In agreement with its effect on drug accumulation, BSO pretreatment also increased VP-16-stimulated cleavable complex formation between DNA topoisomerase II and cellular DNA. BSO treatment also led to a significant increase in acid-precipitable VP-16 levels in MCF7/VP, but not MCF7/WT cells. In contrast, no clear effects of BSO on drug efflux were observed and drug retention was only minimally increased after BSO treatment of both MCF7/WT and MCF7/VP cells and no difference between the two cell lines was detected. Thus, chemosensitisation by BSO appeared to be mediated through increased intracellular drug concentrations and/or protein binding.

AB Prospects for the prevention of cardiovascular disease are excellent now that modifiable predisposing lifestyles and personal attributes have been identified. Multivariate risk profiles facilitate the efficient selection by physicians of high-risk candidates for preventive measures. This paper reviews the public health measures that can improve the average level of major risk factors in the general population and educate the public to make healthier choices in their living habits. The potential for secondary prevention continues to improve, with thrombolytic therapy, beta-blockers, ACE inhibitors, anticoagulants, platelet inhibitors, myocardial revascularisation and aggressive risk factor management in persons who have survived clinical events. The need for trials - to determine the efficacy of correcting dyslipidaemia in the elderly, in women and in blacks, and to examine the benefit of antihypertensive therapy in preventing coronary disease using agents that do not adversely affect lipids or glucose tolerance - is stressed, as is the need to make a serious effort to prevent hypertension.

AB Background. A conceptual framework is described for a broad cost-benefit evaluation of improved financial access to treatment of untreated affective disorders.
Method. The analysis provides an estimate of the value of resources needed to provide improved access to treatment, and it compares these resources to the value of resources the improved access to treatment might save.
Results. The cost-benefit analyses based on recent cost of mental illness studies provide some evidence that appropriately treating people with untreated affective disorders is cost-beneficial.
Conclusion. Patients, providers and buyers of health care should be further encouraged to pay more attention and to commit more financial resources to the treatment of affective disorders.

AB OBJECTIVE: To characterize the structured abstracts in biomedical journals indexed in MEDLINE(R) over a three-year period as an initial step in exploring their utility in enhancing bibliographic retrieval. DESIGN: The study examined the occurrence of structured abstracts in MEDLINE from March 1989 to December 1991, characteristics of MEDLINE records for articles with structured abstracts, editorial policies of six selected MEDLINE journals on structured abstracts, and a sample of twenty-five structured abstracts from the six journals. RESULTS: The study revealed that the number of structured abstracts in MEDLINE and the number of MEDLINE journals publishing structured abstracts increased substantially between 1989 and 1998. On average, articles with structured abstracts had more access points (Medical Subject Heading [MeSH(R)] terms and text words) than MEDLINE articles as a whole. The average length of the structured abstract was greater than the average length of all abstracts in MEDLINE. CONCLUSIONS: The presence of structured abstracts may be associated with other article characteristics that lead to the assignment of a higher average number of MeSH headings or may itself contribute to the assignment of more headings. The variations in the structured-abstract formats prescribed by different journals may complicate the exploitation of these abstracts in bibliographic retrieval systems. More research is needed on a number of questions related to the quality and utility of structured abstracts.

AB Development of subject-specific Gophers is one method to make valuable health information more accessible to those who need it. The National Library of Medicine has developed a Gopher that provides access to information produced by many areas of the library. Recommendations from subject experts in two areas-AIDS, and toxicology and environmental health-led to the development of two subject-specific Gophers. These two Gopher services provide organized access to resources outside of the library as well as to information produced internally. A number of important issues need to be addressed when selecting and organizing outside resources for inclusion in such a service.

AB Background. Adult T-cell leukemia/lymphoma (ATL) is a malignancy of mature T-cells occurring in patients infected with the human T-cell lymphotropic virus-I. These patients frequently develop a variety of infections throughout their disease course.
Methods. Charts and autopsy reports were reviewed for 41 patients with ATL with follow-up varying from 2 to 120 months. Infectious episodes were identified and documented. Analyses of humoral and cell-mediated immunity were performed. Cell-mediated immunity was assessed in vivo with the Merieux multitest skin test panel. Humoral immunity was assessed by quantitative immunoglobulin levels, by determining human antimouse antibody after murine monoclonal antibody infusion acid by an in vitro immunoglobulin biosynthesis coculture system.
Results. A total of 112 infectious episodes were documented. Fifty-seven serious infections were identified. The incidence of total infections was 1.40/patient-year and for serious infections was 0.71/patient-year. The mean serum IgG and IgA levels were within normal range, the mean IgM level was at the lower limit of normal. Peripheral blood mononuclear cells from all patients studied failed to make meaningful amounts of IgG, M, or A when activated. Peripheral blood mononuclear cells of all of the 13 patients studied suppressed production of immunoglobulin by cocultured normal PBMC. Twenty-three of the 27 patients tested were anergic.
Conclusions. ATL is a profoundly immunosuppressing malignancy. This is manifested by an extremely high incidence of infectious episodes/patient-year. The incidence of infection appears to be greater than for mycosis fungoides, Hodgkin's lymphoma and non-Hodgkin's lymphoma.

AB The two-year pilot phase of the Prostate, Lung, Colorectal, and Ovarian (PLCO) trial concluded September 29, 1994. The goals, organization, operation, and recruitment status of the trial are discussed. The PLCO trial is a 16-year randomized controlled screening trial involving 148,000 male and female participants. Screening for prostate cancer is by prostate specific antigen and digital rectal examination. A coordinating center and 10 screening centers located across the United States, a laboratory for prostate specific antigen and CA125 assays, and a biorepository are the primary components of the trial. Scientific direction is provided by National Cancer Institute scientific staff, a steering committee of study investigators, external expert consultants, and a data monitoring panel. Evaluation of the pilot phase is focused on recruitment; screening operations, including quality assurance; compliance; data management; and blood processing. Pilot phase results are anticipated in 1995.

AB The Prostate cancer Intervention Versus Observation Trial (PIVOT) is a randomized trial designed to determine whether early intervention with radical prostatectomy or expectant management should be the preferred treatment for men with clinically localized prostate cancer. This trial will enroll 2000 participants younger than 75 years of age from 75 Department of Veterans Affairs and National Cancer Institute medical centers. Men will be excluded if they are judged not to be candidates for radical prostatectomy.
Eligible participants will be randomized over a 3-year period and followed for a minimum of 12 years. Follow-up data will include urologic symptoms, disease- and treatment-related morbidity, and disease-specific and overall quality of life. Evidence of disease persistence, recurrence, or progression will be measured by questionnaire, physical examination, prostate specific antigen measure, and bone scan.
The primary study end point will be all-cause mortality. Secondary outcomes will include prostate cancer and treatment-specific morbidity and mortality, health status, predictors of disease-specific outcomes, and cost-effectiveness.

AB Increasing evidence suggests that P-glycoprotein (Pgp) expression can mediate drug resistance in refractory breast cancer. We studied 33 patients with refractory breast cancer enrolled in a pilot study of oral amiodarone as a Pgp antagonist given in combination with infusional doxorubicin or vinblastine. Whenever possible, tumors were biopsied and Pgp expression was assayed, Patients received either 60 mg/m(2) doxorubicin over 96 h or 8.5 mg/m(2) vinblastine over 120 h by continuous intravenous infusion. Beginning with the second cycle of chemotherapy, 600-800 mg amiodarone was given orally each day. Patients who experienced toxicity due to amiodarone but were responding to chemotherapy were placed on quinidine, Partial responses were observed in 9 of 33 patients on study and were sometimes observed after the first cycle of chemotherapy, before amiodarone was given, suggesting that some patients may have responded to treatment because of the infusional schedule. Toxicities were primarily the known side effects of the antineoplastic agents and of amiodarone, The major amiodarone toxicity was gastrointestinal, with nausea, vomiting, anorexia, or diarrhea being noted in 21 patients. Biopsy samples were obtained from 29 patients acid in 21 cases, viable tumor tissue was present and the results were interpretable. Of the 21 samples, 9 had Pgp expression as determined by immunohistochemical staining; 12 were considered negative. The presence of Pgp expression was associated with an acceleration of the time to treatment failure. Whereas normal-tissue toxicities related to the combination of a Pgp antagonist with chemotherapy were not observed, amiodarone was associated with too many untoward effects to be utilized as a drug resistance-reversing agent.

AB Mutational inactivation of the p53 tumor suppressor gene is an infrequent event in human nasopharyngeal carcinoma (NPC), a malignancy showing a high incidence in southern China and southeast Asia. To examine the possible involvement of an inactivated p53 pathway in nasopharynx carcinogenesis, we have screened primary NPC biopsies for possible point mutations in WAF-1/CIP-1/p21, an effector gene transcriptionally regulated by and functioning as a mediator of the p53 tumor suppressor gene. Mutations in WAF-1/CIP-1/p21 might mimic p53 mutations in tumors having wild-type p53 such as most NPCs. The mutational analysis of WAF/CIP/p21 by PCR-single strand conformational polymorphism-direct sequencing revealed no point mutation in 41 primary NPC biopsies. A codon 31(ser-->arg) polymorphism was, however, detected. A striking difference in the distribution of the serine (WAF-ser) and arginine (WAF-arg) forms of WAF-1/CIP-1/p21 was observed when normal healthy Caucasians and Chinese were compared (P < 0.0001). The majority of Caucasians examined were found to be homozygous for WAF-ser (89%, n = 65), while Chinese living in areas of high NPC incidence show a greater than 86% homozygous or heterozygous WAF-arg (Taiwan, n = 66; Hunan, n = 32). The two forms of WAF-1/CIP-1/p21 were examined for potential functional differences in their ability to inhibit cyclin-dependent kinases and turner cell growth. No significant differences were detected. Furthermore, no association between WAF-1/CIP-1/p21 genotype and NPC risk was observed in a case-control study of 76 NPC cases and 66 normal controls conducted in Taiwan. We conclude from this study that: (a) mutational inactivation of WAF-1/CIP-1/p21 is not involved in the genesis of NPC; (b) there is race-dependent WAF-1 polymorphism; and (c) the lack of functional differences between the two forms of WAF-1, and the lack of an association between WAF-1 genotype and disease, argue against a causal role of this gene in the genesis of NPC.

ID INFECTION
AB Neopterin, a marker of cellular immune activation, was elevated in patients who had cervical cancer in previous studies. To examine neopterin in the presence of precursors to cervical cancer (i.e., cervical intraepithelial neoplasia) we measured serum levels in 185 colposcopy patients in Jamaica, a country with high cervical cancer incidence, and in 72 age-matched Jamaican women selected from a large population-based sample. We also measured serum levels of beta-2-microglobulin, another commonly used marker of immune activation. Neopterin and beta-2-microglobuIin levels were not elevated in colposcopy patients; neither were they related to severity of cervical neoplasia. In multivariable analysis, neither adjustments for detection of cervical human papillomavirus DNA by PCR nor detection of antibodies to human T-cell lymphotropic virus type I (a retrovirus endemic to Jamaica) altered our findings. The absence of a serologically detectable increase in cellular immune activation linked to cervical intraepithelial neoplasia suggests that the immunological response to cervical intraepithelial neoplasia does not involve substantial systemic cellular immune activation.

Improved quality and resolution of chromosome banding allowed a refined localization of the erbB-3 protooncogene from chromosome band 12q13 to subbands 12q13.2-13.3. This procedure can be used for direct and precise mapping of single-copy genes on both normal and cancer-cell-rearranged chromosomes.

AB Thymidylate synthase (TS) is the target enzyme for 5-fluorouracil (5-FU). We have correlated TS protein and gene expression with the response in patients with colorectal (n = 9) and gastric cancer (n = 12) treated with infusional 5-FU plus leucovorin (LV) or infusional 5-FU/LV and cisplatin, respectively. TS protein expression was analyzed by Western blot using TS106 monoclonal antibody and densitometry scanning. TS gene expression was measured by PCR analysis using beta-actin as an internal standard and expressed as a TS:beta-actin mRNA ratio. A close linear relationship was noted between TS protein expression and TS gene expression (r(2) = 0.60) for the 21 tumor samples analyzed. TS immunohistochemical staining on 15 of the 21 samples revealed that the TS staining intensity correlated closely with TS protein and mRNA expression. In two biopsy samples, TS protein levels and TS gene expression did not correlate; however, one of these exhibited a focal TS staining pattern.
Both the TS protein level and TS gene expression were significantly associated with response to 5-FU-hased therapy. Patients with responsive disease had a mean TS protein level of 0.17 +/- 0.03 arbitrary units (range, 0.05 to 0.38), whereas in patients whose tumors did not respond, the mean TS protein level was significantly higher 0,60 +/- 0.09 (range, 0.06 to 1.01; P < 0.01). A similar pattern was noted with TS gene expression. In patients with responsive disease, the mean TS:beta-actin gene ratio was 1.36 +/- 0.3 (range, 0.5-3.3 x 10(-3)). In contrast, biopsies from patients with unresponsive disease had a mean TS:beta-actin gene ratio of 15.4 +/- 2.6 x 10(-3) (range, 2.7-35.9; P < 0.01). TS protein and TS mRNA expression are highly correlated, and each predict for response to 5-FU/LV-based chemotherapy in patients with colorectal and gastric cancer.

ID P53 MUTATIONS; ASSOCIATION; TUMORS; GENE
AB The growth arrest mediated by p53 is caused at least in part by the p53 mediated expression of p21 (p21(waf1/Cip1)). Since only one-third of primary Burkitt's lymphomas (BL) demonstrate mutations in the p53 gene, we examined the structural integrity of the p21 coding region by single-strand conformational polymorphism and DNA sequence analysis to determine the extent to which this gene is mutated in BL. Of 34 BLs analyzed, a frequent change (38%) at codon 31 that replaced Ser with Arg was found in 13 samples, 10 of which were from Africa. This change at codon 31 is also detected in peripheral blood DNA from normal subjects and may thus represent a polymorphism. One BL cell line, DH978, carried a change at codon 63: Phe to Leu. This mutation was heterozygous, and both the wild-type and the mutated p21 mRNA were expressed in the tumor cell Line. By transfection experiments, the mutant p21 was less efficient in suppressing clonogenicity than wild-type p21. To our knowledge, this is the only mutation described in p21. The availability of this mutant p21 should further help in functional studies of p21.

AB CDKN2 (p(16INK4A)/MTS1) and p(15INK4B)/MTS2 have been shown recently to be potent inhibitors of the cyclin D/cyclin-dependent kinase 4 compler. Both genes are candidates for the putative tumor suppressor gene located at chromosome 9p21. We examined a series of 14 hematopoietic cell lines and 117 primary lymphoid tumors for deletion and mutation of these genes. The primary tumors included 65 T-cell malignancies and 52 B-cell malignancies. The cell line study revealed 4 of 4 T-ALL lines to have homozygous deletions of CDKN2. Two of the 4 lines also show ed homozygous deletions of MTS2, while the remaining 2 lines retained both MTS2 alleles. In the primary tumors, homozygous deletions of both CDKN2 and MTS2 were found in 35% of the T-ALL/lymphoblastic lymphoma (8 of 23), Homozygous deletions of both genes also occurred in 1 of 3 precursor B-ALLs. PCR-single strand conformational polymorphism analysis of CDKN2 exons 2 and 3 and MTS2 exon 2 failed to demonstrate mutations in either CDKN2 or MTS2 in any of the T- or B-cell malignancies, with two possible exceptions. These results are consistent with a role for CDKN2 and/or MTS2 in the pathogenesis of some IS mphoid leukemia/lymphomas, particularly in T-ALL/lymphoblastic lymphoma.

LA English
DT Note
AB We examined the genomic status of cyclin-dependent kinase- 4 and -6 inhibitors, p16(INK4), p15(INK4B), and p18, in 40 primary lung cancers and 31 metastatic lung cancers. Alterations of the p16(INK4) gene were detected in 6 (2 insertions and 4 homozygous deletions) of 22 metastatic non-small cell lung cancers (NSCLCs; 27%), but none were detected in 25 primary NSCLCs, 15 primary small cell lung cancers (SCLCs), or 9 metastatic SCLCs, indicating that mutation in the p16(INK4) gene is a late event in NSCLC carcinogenesis. Although three intragenic mutations of the p15(INK4B) gene were detected in 25 primary NSCLCs (12%) and five homozygous deletions of the p15(INK4B) gene were detected in 22 NSCLCs (23%), no genetic alterations of the p15(INK4B) gene were found in primary and metastatic SCLCs. The p18 gene was wild type in these 71 lung cancers, except 1 metastatic NSCLC which showed loss of heterozygosity. We also examined alterations of these three genes and expression of p16(INK4) in 21 human lung cancer cell lines. Alterations of the p16(INK4) and p15(INK4B) genes were detected in 71% of the NSCLC tell lines (n = 14) and 50% of the NSCLC cell lines (n = 14), respectively, but there were none In the 7 SCLC cell lines studied. No p18 mutations were detected in these 21 cell lines. These results indicate that both p16(INK4) and P14(INK4B) gene mutations are associated with tumor progression of a subset of NSCLC, but not of SCLC, and that p15(INK4B) mutations might also be an early event in the molecular pathogenesis of a subset of NSCLC.

AB Epidemiological and laboratory animal model studies have suggested that nonsteroidal anti-inflammatory drugs reduce the risk of development of colon cancer. The present study was designed to investigate the chemopreventive action of 160 and 320 ppm (equivalent to 40 and 80% maximum tolerated doses) sulindac, a nonsteroidal anti-inflammatory drug, fed during initiation and postinitiation stages and 320 ppm sulindac fed during promotion/progression stages of azoxymethane-induced colon carcinogenesis in male F344 rats. Also investigated was the modulating effect of this agent on the colonic mucosal and tumor phospholipase A(2), phosphatidylinositol-specific phospholipase C, lipoxygenase, and cyclooxygenase activities. At 5 weeks of age, groups of male F334 rats were fed control diet or diets containing 160 and 320 ppm of sulindac. At 7 weeks of age, all animals except those in the vehicle-treated groups were given two weekly s.c. injections of azoxymethane at a dose rate of 15 mg/kg body weight/week. Animals intended for tumor promotion/progression study were administered 320 ppm of sulindac in diet starting at 14 weeks after a second azoxymethane treatment. All animals continued on their respective dietary regimen until the termination of the experiment at 52 weeks after the carcinogen treatment. Colonic tumors were evaluated histopathologically. Colonic mucosa and tumors were analyzed for phospholipase A(2), phosphatidylinositol-specific phospholipase C, prostaglandin E2, cyclooxygenase, and lipoxygenase acti,ities. The levels of sulindac and its metabolites in stomach, cecal, and fecal contents and in serum were analyzed, The results indicate that dietary sulindac at 160 and 320 ppm levels inhibited the incidence of invasive and noninvasive adenocarcinomas of the colon (P < 0.01-0.001) as well as their multiplicity (P < 0.01-0.0001) in a dose-dependent manner. Also, feeding sulindac during promotion/progression stages significantly suppressed the incidence (P < 0.0001) and multiplicity (P < 0.0001) of colonic adenocarcinomas. Dietary sulindac also suppressed the colon tumor volume by >52-62% compared to the control diet. Dietary sulindac significantly decreased the activities of phosphatidy linositol-specific phospholipase C (32-51%) and levels of prostaglandin E(2) (>40% in the colonic mucosa and tumors, but it had no significant (P > 0.05) effect on phospholipase A(2) activity, The formation of cyclooxygenase metabolites, particularly prostaglandin E(2), prostaglandin F-2 alpha, prostaglandin D-2, 6-ketoprostaglandin F-1 alpha, and thromboxane B-2, and lipoxygenase metabolites such as 8(S)- and 12(S)-hydroxyeicosatetraenoic acids were significantly reduced in colonic mucosa and tumors of animals fed 320 ppm sulindac. Also, animals fed 320 ppm sulindac showed increased levels of microbial metabolites of sulindac in cecal and fecal contents and in serum as compared to those fed 160 ppm sulindac, Although the exact mechanism by which sulindac inhibits colon tumorigenesis remains to be elucidated, it is likely that its chemopreventive action, at least in part, mag be related to the modulation of arachidonic acid metabolism.

AB The present study was directed to characterizing the reversion of neoplastic epidermal JB6 RT101 cells by AP-1 inhibiting drugs, Treatment of tumorigenic JB6 RT101 cells with retinoic acid (RA), fluocinolone acetonide (FA) or forskolin (FN) induced drug dependent (reversible) reversion of transformation. A synergistic effect on reversion was found with the three drugs in combination. Cells reverted by these three drugs also showed reduced levels of AP-1 transcription factor activity. After long term exposure of RT101 cells to FA, enrichment of hat revertants occurred in the population while a few unreverted cells formed foci. These unreverted cells appeared to be FA-resistant. Cloning of cells following RA treatment revealed stable reversion at least 2 months after drug withdrawal, Stable revertants showed lower basal AP-1 activity than RT101 cells (P < 0.01) and unstable revertants returned to transformed phenotype and elevated AP-1 activity within days following drug withdrawal. To our knowledge this is the first demonstration that drug induced reversion co-selects for reduced AP-1 activity, These data suggest that the JB6 RT101 cell line is a useful cell model for studying reversion of transformation and that inhibition of AP-1 activity may be one molecular mechanism of reversion, Considering the development of resistance with FA alone and the relative inefficiency of RA or FN alone, combinations of the three AP-1 activity inhibitors RA, FA and FN may be useful for further animal and clinical studies.

AB 2-Amino-3-methylimidazo[4,5-f]quinoline (IQ) and 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) are heterocyclic amines (HAs) found in cooked meats, Both compounds are mammary gland carcinogens in rats, The initiation of carcinogenesis by the HAs is believed to be associated with their DNA adduct formation that occurs after metabolic activation of the parent amines via cytochrome P-450-mediated N-hydroxylation and esterification, To assess the capacity of the human mammary epithelium to metabolically activate the HAs, we used the P-32-postlabeling method to measure the levels of DNA adducts in a culture of human mammary epithelial cells exposed to IQ, PhIP or their N-hydroxylamine metabolites. Whereas 50 mu M parent amines did not form detectable levels of DNA adducts ill cultured human mammary epithelial cells after 24 h incubations, concentrations as low as 1 mu M N-hydroxylamines produced detectable levels of adducts after 2 h incubations, N-Hydroxy-PhIP formed higher adduct levels than N-hydroxy-IQ at all concentrations tested, For example, following a 2 h incubation at 50 mu M, adduct levels (per 10(7) nucleotides) were 674 and 16 for N-hydroxy-PhIP and N-hydroxy-IQ, respectively, At similar initial adduct levels (10-11/10(7) nucleotides), 60-80% of IQ- and PhIP-DNA adducts were removed after 24 h, indicating that the mammary epithelial cell culture showed efficient repair of HA adducts, Whereas neither IQ nor PhIP was cytotoxic, both N-hydroxy-IQ and N-hydroxy-PhIP were cytotoxic as assessed by a dose-dependent inhibition of colony formation, After exposure to 0.1, 1, 10 or 50 mu M N-hydroxy-PhIP (or N-hydroxy-IQ), colony formation was 103 (94), 84 (74), 37 (29) and 3 (2)% of the control values, respectively, Only N-hydroxy-PhIP (at 10 and 50 mu M), however, was cytotoxic as assessed by the MTT cell survival assay (which measures the capacity of mitochondria to metabolize a tetrazolium salt), The ability of the N-hydroxylamines to form DNA adducts and to be cytotoxic in a culture of human mammary epithelial cells may implicate these metabolites as proximate carcinogenic forms of IQ and PhIP in the human mammary gland, However, whether there are inter-individual differences in N-hydroxylamine metabolism, adduct formation and repair in human mammary epithelial cells requires further study. The results from this study support the usefulness of cultured human mammary epithelial cells for studies on the genotoxicity and metabolism of the N-hydroxylamines of HA food mutagens.

AB Specific cDNA probes for transforming growth factor beta s (TGF-beta s) 1, 2, and 3 and TGF-beta types I, II, and III receptors were used to study expression of the mRNAs of the different TGF-beta ligand and TGF-beta receptor isoforms in cultured non-small cell lung cancer (NSCLC) cells and small cell lung cancer (SCLC) cells. Expression of TGF-beta 1 mRNA was detected in both cell types using Northern blot hybridization, with the level of expression of this mRNA being higher in several NSCLC cell lines. In addition, expression of TGF-beta 2 and TGF-beta 3 mRNAs was also detected in NSCLC and SCLC cells but at levels that were lower than that of TGF-beta 1 mRNA. Besides expression of a 3.4-kilobase (kb) TGF-beta 3 transcript, a smaller 2.8-kb TGF-beta 3 transcript was detected in some NSCLC and SCLC cells. TGF-beta 1 and TGF-beta 2 proteins were detected in the conditioned media of NSCLC and SCLC cells, with the levels being higher in several NSCLC cells than in SCLC cells. Expression of TGF-beta types I and II receptor mRNAs was also detected in most NSCLC and SCLC cells, with expression of a 5.5-kb type I receptor mRNA being higher than that of a 5.5-kb type II receptor mRNA in both cell types. In contrast, a 6-kb TGF-beta type III receptor mRNA was detected in only some NSCLC cells and could not be detected in the SCLC cells examined. Also, there was an inverse relationship between the level of expression of the 5.5-kb TGF-beta type I receptor mRNA and that of the 6-kb TGF-beta type III receptor mRNA. Addition of TGF-beta 1 and TGF-beta 2 proteins resulted in an increase in the mRNAs for TGF-beta s 1 and 2 and an increase in the amount of TGF-beta 1 protein in some NSCLC cells, indicating that these cells are responsive to TGF-beta and its effects. At the same time, a differential change in expression of the 2.8- and 3.4-kb TGF-beta 3 transcripts was detected in some lung cancer cells following the addition of TGF-beta 1 and TGF-beta 2. Also, addition of TGF-beta 1 to NSCLC cells inhibited colony formation of some of these cells in soft agarose in a dose-dependent manner. These results show that some lung cancer cells are responsive to the effects of TGF-beta and suggest that TGF-beta may have a role in controlling the proliferation of these cells.

((+)- and (-)-trans-2), in which an exocyclic amino group of deoxyadenosine (A*) or deoxyguanosine (G*) has been alkylated by trans opening at C-10 of the epoxide group of either the (+)-(R,S,S,R)- or (-)-(S,R,R,S)-enantiomer of (+)-7 beta,8 alpha-dihydroxy-9 alpha, 10 alpha-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE in which the benzylic 7-hydroxy group and the epoxide oxygen are trans), exhibit more than one fluorescence lifetime. Decay profiles of the oligomers, measured at 15 degrees C with excitation and emission wavelengths of 335 and 400 nm, respectively, have been analyzed using a triple-exponential decay law. Results for (+)- and (-)-trans-1 and -2 have been compared with results for the modified, single-stranded oligonucleotides ((+)- and (-)-trans-SS-1, and (+)- and (-)-trans-SS-2) and for the cis and trans opened products formed on alkylation at the g-amino group of 2'-deoxyadenosine 5'-phosphate by (+)-(R,S,S,R)-BPDE ((+)-trans- and(+)-cis-A). The profiles of(+)-trans- and (+)-cis-A are well represented by single-exponential decay laws with lifetimes of 86 and 110 +/- 3 ns, respectively. For the single- and double-stranded oligomer adducts, which exhibit at least three fluorescence lifetimes, two of the lifetimes are short (0.5-14 +/- 1 ns) and one is long (35-59 +/- 3 ns). The fluorescence lifetimes and the amplitudes of the long-lived components in the decay profiles of the double-stranded oligomer adducts are generally smaller than those for the corresponding single-stranded adducts. The data provide evidence that the double-stranded oligomer adducts exist as multiple conformations. Previously reported NMR results suggest that the short-lifetime fluorescence components are due to major adduct conformations in which the pyrenyl group is intercalated ((+)- and (-)-trans-1) or lies in the minor groove ((+)- and (-)-trans-2). The observation of long lifetime fluorescence species for the double-stranded oligomers is consistent with the presence of minor conformations (similar to 1-5%) in which the double-stranded oligomer either is locally denatured or is a mixture of locally denatured double-stranded conformations and equilibrium concentrations of single-stranded oligomers.

AB The eight products resulting from opening of either enantiomer of styrene oxide at the alpha- or beta-carbon by the 1- or N-6-positions of adenosine were prepared and their configurations assigned. These markers allowed the mechanism of aralkylation of adenosine by styrene oxide to be investigated. It was found that formation of alpha-substituted products at the 1-position of adenosine involved total inversion of stereochemistry, whereas at the N-6-position inversion: retention was similar to 6:1. These differences in stereochemistry suggest that a more ionic form of styrene oxide is involved in N-6-aralkylation than in 1-aralkylation of adenosine. In the course of these studies, it was found that 1-substituted adenosines at the alpha- and beta-carbon of styrene oxide undergo Dimroth rearrangement at neutral pH and 37 degrees C and that the former compound also deaminates fairly readily under these conditions.

AB Site-specifically modified oligonucleotides were obtained in milligram quantities by reacting racemic 3t,4r-dihydroxy-1,2t-epoxy-1,2,3,4-tetrahydrobenzo[c]phenanthrene (B[c]PhDE-2, or anti-B[c]PhDE) with the single deoxyadenosine (dA) residue in the oligodeoxynucleotide d(CTCTCACTTCC). Enzyme digestion of the covalently modified oligonucleotides with the exonuclease spleen phosphodiesterase yielded covalently linked B[c]PhDE-N-6-deoxyadenosyl monophosphate (dAMP) adducts. Comparisons of the reverse phase HPLC retention times and CD spectra of these B[c]PhDE-3'-dAMP mononucleotide adducts, with those of standards derived from the reaction of the enantiomers (+)- and (-)-anti-B[c]PhDE with 3'-dAMP, show that two major oligonucleotide adducts (I and II) were obtained upon reacting racemic anti-B[c]PhDE with d(CTCTCACTTCC). In oligonucleotide adduct I, the lesion is a (+)-trans-anti-B [c]PhDE-N-6-dA residue, and in oligonucleotide adduct II it is a (-)-trans-anti-B[c]PhDE-N-6-dA residue. These assignments were further confirmed using a standard P-32 postlabeling assay of B[c]PhDE-3'-dAMP mononucleotide adducts obtained from the digestion of oligonucleotides I and II by spleen phosphodiesterase. The melting points (T-m) of duplexes of modified oligonucleotides I and II and their natural complementary strands are not affected significantly by the presence of the covalently bound benzo[c]phenanthrenyl residues. Opposite stereoselective resistance to enzyme digestion by the exonucleases snake venom phosphodiesterase and spleen phosphodiesterase is exhibited by the stereoisomeric (+)-trans- and (-)-trans-anti-B[c]PhDE-modified oligonucleotide adducts I and II; these results are consistent with the intercalative insertion of the benzo[c]phenanthrenyl residues on the 5'-side of the modified dA residue in adduct I, and its insertion on the 3'-side of the dA residue in adduct II, as observed in the duplexes by high resolution NMR techniques [Cosman et al. (1993) Biochemistry 32, 12488-12497, and Cosman et al., Biochemistry, in press].

ID CYTOCHROMES-P450; L651582; CALCIUM; AGENT
AB Metabolism of a new antitumor agent, CAI (NSC 609974), was investigated in human liver tissue in vitro and in plasma and urine of patients receiving CAI. Metabolites identified by HPLC following C-14-labeled CAI incubation with human liver microsomes and reported as percentage of total metabolites formed were M1 (0-3.4%), M2 (4.5-33%), M3 (60-79%), and M4 (7.2-19%). Ketoconazole, an inhibitor of cytochrome P450 3A4, prevented formation of M1, M3, and M4 (concentration of drug that inhibited metabolite formation by 50% when compared to maximum uninhibited activity, 3.0 mu M), but only weakly inhibited formation of M2 (concentration of drug that inhibited metabolite formation by 50% when compared to maximum uninhibited activity, > 50 mu M). CAI incubated with recombinant human P450 3A4 microsomes produced metabolites M3 and M4. Conjugation of M3, most likely a glucuronide, was observed after incubation of C-14-labeled CAI and UDP-glucuronic acid with human liver 13,000 x g supernatant. Plasma samples from patients receiving CAI contained CAI (3.1-5.0 mu g/ml), M1 (0.9-2.6 mu g/ml), and M2 (1.0-2.2 mu g/ml). CAI and M3 but not M4 were observed in the urine samples, After incubation of the urine samples with beta-glucuronidase, CAI concentrations increased 67%, M3 increased up to 9-fold, and M4 was detected. CAI is metabolized in vitro and in vivo by both Phase I and Phase II enzymes and is metabolized to M3 and M4 by P450 3A4. These studies suggest that elevated levels of CAI may result from P450 3A4 inhibition by ketoconazole if these two drugs are coadministered. Correlation between CAI metabolism in vitro and results obtained in patients demonstrates the usefulness of liver metabolism studies in vitro in the early stages of drug development.

AB A new retroviral vector, pSXLC/pHa, was constructed to coexpress drug-selectable markers with a second gene of interest as a part of a bicistronic mRNA in a retroviral vector using an internal ribosome entry site (IRES) from encephalomyocarditis virus. This system was used to develop a new retroviral vector pHa-MDR-IRES-TK which expresses a single mRNA from which translation of the MDR1 gene is cap dependent and translation of the herpes simplex virus thymidine kinase gene is IRES dependent. The pHa-MDR-IRES-TK transfectants showed high levels of P-glycoprotein expression and multidrug resistance. More than 95% of the vincristine-resistant cells transfected or transduced with pHa-MDR-IRES-TK showed hypersensitivity to ganciclovir, which selects against cells expressing herpes simplex virus thymidine kinase. An amphotropic retrovirus titer of 7.8 x 10(4)/ml was obtained with this vector. This safety-modified vector should be useful for introducing the MDR1 gene into bone marrow cells to protect normal cells from the toxic effects of cancer chemotherapy because this vector allows the elimination of cancer cells that have been unintentionally transduced with the MDR1 vector.

AB We describe recent advances in understanding a mechanism of peripheral tolerance that operates through antigen-induced programmed cell death of mature T lymphocytes. A three-phase model of this process, termed propriocidal regulation, involves: (i) activation of T cells to express growth lymphokines and their receptors, (ii) lymphokine-stimulated cell-cycle progression, and (iii) T cell receptor reengagement leading to programmed cell death. Based on this model, antigen was used to treat experimental allergic encephalomyelitis and caused profound deletion of autoreactive, encephalitogenic T cells as well as dramatic clinical and pathological improvement of the disease. The potential strengths and weaknesses of this approach to the clinical treatment of T-cell-mediated diseases are discussed. (C) 1995 Academic Press, Inc.

AB A case-control study was conducted at two institutions to determine whether the absolute CD4 lymphocyte count or the percentage of lymphocytes bearing the CD4 marker (i.e., the CD4 percentage) is a more accurate indicator of underlying immune status in splenectomized patients infected with human immunodeficiency virus (HIV). Each of nine splenectomized HIV-infected cases was matched with six nonsplenectomized HIV-infected controls-three matched for CD4 lymphocyte count and three for CD4 percentage. In analyses including the eight cases with an initial CD4 lymphocyte count of >200/mm(3), controlling for the CD4 count revealed differences between cases and controls in terms of CD4 percentage (range, 10%-41% and 17%-54%, respectively; P<.01) and Centers for Disease Control and Prevention (CDC) clinical stage (P =.06). Controlling for the CD4 percentage revealed a significant difference between cases and controls in terms of CD4 count (range, 396-1,040 and 55-784 cells/mm(3), respectively; P <.01) but not CDC clinical stage (P >.7). These data suggest that the numerical relationship between the CD4 lymphocyte count and the CD4 percentage among splenectomized HIV-infected patients with more than 200 CD4 cells/mm(3) differs from that among nonsplenectomized patients. The CD4 percentage appears to be a more accurate indicator of the underlying level of immune function in the former group of patients.

AB We characterized 27 episodes of fungemia in 22 children infected with the human immunodeficiency virus (HIV). Fungemia in these patients presented as a community-acquired infection in the setting of outpatient total parenteral nutrition or intravenous antibiotic therapy through a chronically indwelling central venous catheter (CVC). Fungemia developed only in patients with CVCs (P <. 001). Non-albicans Candida species, Torulopsis glabrata, Rhodotorula rubra, and Bipolaris spicifera constituted 52% of all causes. Fungemia was detected early, within a median of 2.4 days after the onset of new fever, which permitted prompt administration of amphotericin B (mean dosage, 0.7 mg/[kg . day]; median duration, 19 days), CVCs were removed in 23 (85%) of the episodes. We conclude that fungemia in HIV-infected children often presents as a community-acquired infection, is frequently due to newly emerging opportunistic fungi, and can be managed, with a high level of success (95% survival with no posttherapeutic sequelae), by early diagnosis, prompt initiation of amphotericin B therapy, and removal of the CVC.

AB Cytomegalovirus (CMV) infection is common in patients infected with human immunodeficiency virus. Hemorrhagic cystitis and tubulointerstitial nephritis have been recognized as complications of CMV infection, and these complications lead to hematuria and compromised renal function. We describe a case of CMV infection of the ureters in a child with vertically acquired human immunodeficiency virus infection; the child presented with severe suprapubic pain, and prolonged macroscopic hematuria and intermittent acute renal failure developed subsequently.

AB Fifty cocaine-dependent patients completed a 2-week double-blind, double-dummy, parallel-group comparison of four dosage levels of diethylpropion and placebo. This clinical trial was designed to evaluate both diethylpropion's ability to attenuate cocaine cue-induced craving and its potential for development as a medication with cocaine-agonist properties. The results indicated that diethylpropion was not superior to placebo and confirmed earlier reports that craving for cocaine diminishes over the course of an inpatient hospitalization. Moreover, the results showed that the cocaine cue-induced craving paradigm employed is effective in stimulating craving for cocaine. Medications that are effective in attenuating this type of ''conditioned'' craving may have relevance to the breaking of the cycle of relapse and the long-term treatment of cocaine dependence. Diethylpropion may not be an appropriate candidate for future medication development because of its lack of obvious therapeutic efficacy and the emergence of a significant number of side effects. However, a cocaine-agonist medication strategy may be appropriate for a subgroup of cocaine-dependent patients with coexisting attention deficit-hyperactivity disorder.

AB This paper presents a practical program, called sim2, for building local alignments of two sequences, each of which may be hundreds of kilobases long. sim2 first constructs n best non-intersecting chains of 'fragments', such as all occurrences of identical 5-tuples in each of two DNA sequences,for any specified n greater than or equal to 1. Each chain is then refined by delivering an optimal alignment in a region delimited by the chain. sim2 requires only space proportional to the size of the input sequences and the output alignments, and the same source code runs on Unix machines, on Macintoshes, on PCs, and on DEC Alpha PCs. We also describe an application of sim2 for aligning long DNA sequences from Escherichia coli. sim2 facilitates contig-building by providing a complete view of the related sequences, so differences can be analyzed and inconsistencies resolved Examples are shown using the alignment display and editing functions from the software tool ChromoScope.

DT Article
ID NUCLEAR MAGNETIC-RESONANCE; MOLECULAR-PROPERTIES; SUBSTITUENT; CONSTANTS
AB An approach for modeling long range deuterium isotope effects on C-13 chemical shifts, based on ab initio calculations of the differences of atomic charges between parent and deuterated molecules, is proposed. The total atomic charges were calculated for a series of molecules consisting of two benzene rings linked directly or via different groups, the so called binuclear aromatic molecules: biphenyl, trans-stilbene, cis-stilbene, diphenylacetylene, diphenylbutadiene and their I-deuterated derivatives. The basis sets used were: STO-3G, 6-31G, 6-31G** and MIDI. The deuteration site, i.e. C-D bond was simulated by the shortening of the corresponding C-H bond length by 0.012 Angstrom or by the reduction of CCH in-plane or out-of-plane bending angle by 1.3 degrees and 2 degrees, respectively. Calculations were performed both for the X-ray geometries and 6-31G fully optimized geometries. The charge differences from Lowdin but not from Mulliken population analysis, calculated with 6-31G, 6-31G** and MIDI basis sets, showed good correlation with the measured longrange deuterium isotope effects on C-13 chemical shifts of C-atoms, five, six, seven, eight, ten and twelve bonds away from the site of deuteration. This correlation holds only for bond shortening but not for bending angle changes, which corresponds to the predominance of stretching over bending mode contributions to isotope effects. The vibrational analysis (6-31G) revealed no coupling of C-D stretching with the vibrations of remote C-atoms. Therefore, we assume that the symmetry breaking due to unsymmetrical deuterium substitution produces a small electric dipole moment by an unbalance in the normal vibrations which in turn polarizes pi-electrons, giving rise to charge changes throughout the molecule. Calculated charge redistribution due to deuterium, experimentally also observed by microwave spectroscopy, might induce long-range deuterium isotope effects on C-13 chemical shifts in agreement with the postulated C-C pi-bond polarization contribution to C-13 chemical shifts.

PROTEIN; HIGH-AFFINITY; EGF RECEPTOR; GRB2
AB Background: Signal transduction by growth factor receptor protein-tyrosine kinases is generally initiated by autophosphorylation on tyrosine residues following ligand binding. Phosphotyrosines within activated receptors form binding sites for the Src homology 2 (SH2) domains of cytoplasmic signalling proteins. One such protein, Shc, is tyrosine phosphorylated in response to a large number of growth factors and cytokines. Phosphorylation of Shc on tyrosine residue Y317 allows binding to the SH2 domain of Grb2, and hence stimulation of the Ras pathway. Shc is therefore implicated as an adaptor protein able to couple normal and oncogenic protein-tyrosine kinases to Ras activation. Shc itself contains an SH2 domain at its carboxyl terminus, but the function of the amino-terminal half of the protein is unknown.
Results: We have found that the Shc amino-terminal region binds to a number of tyrosine-phosphorylated proteins in v-src-transformed cells. This domain also bound directly to the activated epidermal growth factor (EGF) receptor. A phosphotyrosine (pY)-containing peptide modeled after the Shc-binding site in polyoma middle T antigen (LLSNPTpYSVMRSK) was able to compete efficiently with the activated EGF receptor for binding to the Shc amino terminus. This competition was dependent on phosphorylation of the tyrosine residue within the peptide, and was abrogated by deletion of the leucine residue at position -5. The Shc amino-terminal domain also bound to the autophosphorylated nerve growth factor receptor (Trk), but bound significantly less well to a mutant receptor in which tyrosine Y490 in the receptor's Shc-binding site had been substituted by phenylalanine.
Conclusion: These data implicate the amino-terminal region of Shc in binding to activated receptors and other tyrosine-phosphorylated proteins. Binding appears to be specific for phosphorylated tyrosine residues within the sequence NPXpY, which is conserved in many Shc-binding sites. The Shc amino-terminal region bears only very limited sequence identity to known SH2 domains, suggesting that it represents a new class of phosphotyrosine-binding modules. Consistent with this view, the amino-terminal Shc domain is highly conserved in a Drosophila Shc homologue. Binding of Shc to activated receptors through its amino terminus could leave the carboxy-terminal SH2 domain free for other interactions. In this way, Shc may Function as an adaptor protein to bring two tyrosine-phosphorylated proteins together.

AB Smoke, either from cigarette smoking or from burning of organic fuels, has been proposed to be a major environmental risk factor for a variety of human diseases. Recently, smoke was implicated in cataract, an eye lens opacification which is a major cause of blindness. We have undertaken a study to investigate the effect of wood smoke condensate on the physiological integrity and morphology of organ cultured lenses. Lenses in organ culture are metabolically active and have functional defense systems, thus they provide an appropriate model for studying effects of smoke condensate. Our present study indicates that metabolites of wood smoke condensate accumulate in the lens. The ability of the lenses to accumulate rubidium-86 (mimic of potassium) and choline from the medium is compromised by exposure to smoke condensate. Rubidium efflux studies suggest that the damage is primarily at the uptake level and does not involve an overall increase in membrane permeability. Protein leakage experiments corroborate this suggestion. Histological data show distinct morphological changes such as hyperplasia, hypertrophy and multilayering of epithelial cells.

AB Specular microscopic studies indicate that the size (polymegathism) and shape (pleomorphism) of the hexagonal corneal endothelial cells change in diabetics. Similar morphometric changes of the corneal endothelium have also been experimentally observed in diabetic rats as well as in diabetic and galactose-fed dogs and concomitant administration of aldose reductase inhibitors reduced these morphological changes. The purpose of this study was to examine whether corneal endothelial changes in galactose-fed dogs are reversible by the marked reduction of galactitol production after stopping prolonged galactose feeding. Ten control dogs were fed a normal diet, while 48 dogs were fed a diet containing 30% galactose. The galactose diet was removed from 15 dogs after 24 months at which time pericyte ghosts in the retina had developed and another 15 dogs were removed from the galactose diet after 31 months when retinal microaneurysms had developed. Eighteen dogs remained on galactose diet throughout the study (38 months). Specular microscopy was conducted on members of all groups after 38 months of study and the photographs were analyzed in masked fashion on the Bambi image analysis system. The evaluation of the corneal endothelial cells revealed significant differences in the cell size and density between galactose-fed dogs in the three groups and normal, age-matched control dogs. Corneal endothelial changes were not significantly reduced in dogs fed galactose for either 24 months or 31 months and then fed a normal diet for 14 and 7 months, respectively, indicating that amelioration of endothelial cell changes requires therapy prior to the advent of endothelial morphologic changes.

AB Phosphatidylinositol 4,5-bisphosphate (PIP2) is an important component of several intracellular signaling pathways. It serves as a substrate for phospholipase C, which produces the second messengers inositol 1,4,5-trisphosphate and diacylglycerol. It is also a substrate for a phosphatidylinositol 3-kinase, and regulates the function of a number of actin-binding proteins. PIP2 has been shown recently to serve as a cofactor for a phosphatidylcholine-specific phospholipase D and as a membrane-attachment site for many signaling proteins containing pleckstrin homology domains. The need to stringently regulate the cellular concentration of PIP2 is reflected in part by the fact that there are at least ten distinct mammalian phospholipase C isozymes and multiple mechanisms linking these isozymes to various receptors.

AB The past two years have seen the rapid development of new recognition methods for protein structure prediction. These algorithms 'thread' the sequence of one protein through the known structure of another, looking for an alignment that corresponds to an energetically favorable model structure. Because they are based on energy calculation, rather than evolutionary distance, these methods extend the possibility of structure prediction by comparative modeling to a larger class of new sequences, where similarity to known structures is recognizable by no other means. The strength of the evidence they offer should be judged by objective statistical tests, however, so as to rule out the possibility that favorable scores arise from chance factors such as similarity of length, composition, or the consideration of a large number of alternative alignments. Calculation of objective p-values by analytical means is not yet possible, but it would appear that approximate values may be obtained by simulation, as they are in gapped, global sequence alignment. We propose that the results of threading experiments should include Z-scores relative to the composition-corrected score distribution obtained for shuffled and optimally aligned sequences.

AB Members of the basic helix-loop-helix (bHLH) family of transcription factors have been shown to regulate growth and differentiation of numerous cell types. Cell-type-specific bHLH proteins typically form heterodimers with ubiquitous bHLH proteins, such as E12, and bind a DNA consensus sequence known as an E-box, We used the yeast two-hybrid system to screen mouse embryo cDNA libraries for cDNAs encoding novel cell-type-specific bHLH proteins that dimerize with E12. One of the cDNAs isolated encoded a novel bHLH protein, called scleraxis. During mouse embryogenesis, scleraxis transcripts were first detected between day 9.5 and 10.5 post coitum (p.c.) in the sclerotome of the somites and in mesenchymal cells in the body wall and limb buds, Subsequently, scleraxis was expressed at high levels within mesenchymal precursors of the axial and appendicular skeleton and in cranial mesenchyme in advance of chondrogenesis; its expression pattern in these cell types foreshadowed the developing skeleton, Prior to formation of the embryonic cartilaginous skeleton, scleraxis expression declined to low levels, As development proceeded, high levels of scleraxis expression became restricted to regions where cartilage and connective tissue formation take place, Scleraxis bound the E-box consensus sequence as a heterodimer with E12 and activated transcription of a reporter gene linked to its DNA-binding site. The expression pattern, DNA-binding properties and transcriptional activity of scleraxis suggest that it is a regulator of gene expression within mesenchymal cell lineages that give rise to cartilage and connective tissue.

AB The weaver mouse mutation is a genetic defect of unknown origin that leads to impairment of cerebellar granule neuronal migration and to neuronal cell death, We investigated laminin expression and proteolytic enzyme activity in this migration-deficient mouse mutant in vivo and in vitro to search for a molecular basis for the weaver defect, The weaver cerebellum showed a general increase in immunoreactivity for laminin, for a neurite outgrowth domain of the B2 chain of laminin, and for tissue plasminogen activator compared to the normal animals, Zymographic assays and immunocytochemistry confirmed that tissue plasminogen activator was the proteolytic enzyme synthesized in excess in the weaver mouse cerebellum in vivo. When placed in culture, the weaver granule neurons survived poorly on a laminin substratum, and failed to extend long neurites, unlike the normal cerebellar granule neurons, The cultured weaver granule neurons were proteolytically overactive and secreted excessive amounts of tissue plasminogen activator, which was likely to interfere with their neurite outgrowth potential on a laminin substratum. Indeed, the weaver granule neurons but not the normal neurons degraded laminin from their culture substratum and deposited a neurite outgrowth domain of the B2 chain of laminin onto their surfaces, Electrophysiology showed that the weaver granule neurons had poor resting membrane potentials (-38 V), whereas the normal neurons had normal resting membrane potentials of (-61 V). The resting membrane potentials of the weaver granule neurons were restored to near normal (-59 V) by a protease inhibitor, aprotinin, Aprotinin also rescued the weaver granule neurons from death on a laminin substratum and promoted their neurite outgrowth to the level of the normal animals, These results indicate that increased proteolytic activity accompanied with increased synthesis of laminin, and its B2 chain, distinguish the weaver mutation from the normal animals. These molecular changes may contribute to the impairment of granule neuronal migration and to the neuronal death, characteristic of the weaver mutation. (C) 1995 Academic Press, Inc.

AB The nephric duct of the chick embryo starts to form at about stage 10 of Hamburger and Hamilton ([1951] J. Morphol. 88:49-92) and extends posteriorly, fusing with the cloaca at about the end of the third day of incubation (HH stage 17), Evidence from the literature suggests that the extension involves active migration of the posterior tip, This investigation concerned some molecules that might control this migration: fibronectin, vitronectin, the pl integrin receptor, and NCAM polysialic acid, The concentration of fibronectin in the extracellular matrix was found by immunocytochemistry to be negligible at the posterior end of the duct; treatment of the living embryo with GRGDS failed to halt further extension of the duct; SEM examination of embryos treated with the synthetic peptides of fibronectin GRGDS, GRDGS, SDGR, and GRGES, or with vitronectin, revealed negligible morphological effects on the duct. It is concluded that there is yet no evidence that fibronectin is an important factor in duct migration, NCAM polysialic acid had a similar distribution to fibronectin, but treatment of the living embryo with Endo-N caused cessation of extension of the duct. Endo-N is an enzyme that specifically degrades PSA without affecting the NCAM polypeptide itself, It is suggested therefore that PSA may play an important role in duct extension. The synthetic peptides of fibronectin each produced distinctive patterns of blebbing on the surfaces of cells in trunk mesoderm, but the duct cells were unaffected. GRGES and SDGR caused blebbing on cells in the somites and the anterior segmental plate, though not on cells in the posterior segmental plate, This suggests that integrin receptors change in the anterior segmental plate as the mesoderm forms somites from somitomeres.

AB Murine Lhx3 cDNA isolated from the mouse pituitary cDNA Library encodes a LIM-type homeodomain protein that contains two tandemly repeated LIM domains and the homeodomain, The identities of predicted amino acid sequences between the mouse Lhx3 and Xenopus Xlim-3 genes are 80, 95, and 97% in the LIM domains 1 and 2, and the homeodomain, respectively, and 84% in the entire protein, 5'-RACE procedures and genomic cloning revealed that two distinct N-terminal sequences arise from. two different exons la and Ib, Exon 1a encodes a sequence similar to that of Xlim-3, whereas exon 1b encodes a different N-terminus. It is likely that there are two transcription initiation sites in the Lhx3 gene. The Lhx3 transcripts were detected by whole mount in situ hybridization as early as day E9.5 post coitum in Rathke's pouch and the dosing neural tube. During subsequent development, Lhx3 expression was observed in the anterior and intermediate but not in the posterior lobes of the pituitary, and in the ventral hindbrain and spinal cord. Northern blot analysis of adult tissues showed that Lhx3 mRNA persists in the pituitary. The expression pattern of Lhx3 is well conserved between Xenopus and mouse, underscoring the functional importance of this gene as a regulator of development. A number of established cell lines of pituitary origin express Lhx3 and therefore constitute a useful tool for further study of Lhx3 gene function. (C) 1995 Wiley-Liss, Inc.

AB Obesity and family history of diabetes are both risk factors for non-insulin-dependent diabetes mellitus (NIDDM), but it has been proposed that lean individuals with NIDDM have a greater load of diabetes susceptibility genes. If this is the case, one might expect a high prevalence of NIDDM in relatives of diabetic individuals with a low body mass index (BMI). Among Pima Indians participating in an epidemiological study, prevalence of NIDDM was evaluated in relation to BMI of a diabetic parent or to the average parental BMI when both parents had diabetes in 1,535 offspring from 547 families. Prevalence of NIDDM was also evaluated in relation to BMI of a randomly selected index diabetic sibling in 1,722 siblings from 721 families. NIDDM was diagnosed by an oral glucose tolerance test. Compared with offspring of diabetic parent(s) at the 25th percentile of BMI, the odds ratio (OR) for diabetes in offspring of diabetic parents at the 75th percentile was 0.6 (95% confidence interval [CI] 0.5-0.7), adjusted for age, sex, BMI in offspring, number of diabetic parents, and age at onset of diabetes and sex of the diabetic parent(s). In the analysis according to BMI in a diabetic sibling, the corresponding OR was 0.8 (95% CI 0.6-0.9), Risk ratios were only modestly higher when the analysis was restricted to relatives of subjects whose BMI had been determined before the onset of diabetes. NIDDM in the presence of a low BMI is more strongly familial than that at a higher BMI. This may indicate that a greater load of familial determinants of diabetes is present in leaner diabetic people, and it suggests that these determinants are largely separate from those that result in familial aggregation of obesity.

AB A low acute insulin response (AIR) is a predictor of non-insulin-dependent diabetes mellitus (NIDDM) in insulin-resistant Pima Indians. We have initiated a search for regions of the genome linked with the AIR using sib-pair linkage analysis as a first step in identifying genes that are determinants of this phenotype. Eighteen short tandem-repeat polymorphisms from chromosome 1 were genotyped in over 900 Pima Indians and tested for linkage with NIDDM and in a subset of Pima Indians for linkage with ATR. The anonymous DNA marker D1S198 on chromosome 1p was linked with AIR (P = 0.000056) in 175 sib pairs from 60 families, all with normal glucose tolerance, but no linkage was observed between D1S198 and NIDDM (P = 0.44, 996 sib pairs). Additional markers genotyped on chromosome 1 did not show linkage with AIR or NIDDM. This study indicates that a locus on chromosome 1p may be a determinant of the phenotypic variation seen in the ATR.

AB OBJECTIVE-To determine and compare the abilities of various anthropometric measurements to predict the development of non-insulin-dependent diabetes mellitus (NIDDM) in Pima Indian men and women.
RESEARCH DESIGN AND METHODS-A total of 290 male and 443 female Pima Indians were followed for up to 6 years for the development of NIDDM. A proportional hazards analysis was used to assess the ability of anthropometric measurements evaluated at baseline to predict NIDDM. Receiver operating characteristic (ROC) curves were used to compare individual variables in predicting NIDDM.
RESULTS-In separate models controlled for age and sex, body mass index (BMI), waist circumference, thigh circumference, waist-to-thigh ratio (WTR), weight, and percentage body fat (PBF) estimated by bioelectric resistance each predicted NIDDM, which developed in 30 men and 52 women. The highest incidence rate ratios (IRRs; for 1 SD of a variable) were for WTR in men and for PBF in women, although the confidence interval (CI) for PBF was wide. In stepwise analyses, WTR was the most significant predictor in men (IRR for 1 SD = 1.58, 95% CI = 1.20-2.07), and BMI was the most significant predictor in women (IRR for 1 SD = 1.65, 95% CI. = 1.29-2.11). However, by ROC analyses, thigh circumference was the only variable significantly worse than WTR in men or BMI in women at predicting NIDDM.
CONCLUSIONS-Measurements such as waist circumference, WTR, weight, and BMI may be as useful as more complicated measurements, such as PBF by bioelectric resistance, for identifying groups of individuals whose body habitus places them at high risk of developing NIDDM.

AB Insulin resistance is believed to be a prediabetic condition that results from reduced rates of insulin-mediated glycogen synthesis in skeletal muscle. A decrease in activities of skeletal muscle glycogen synthase and of its regulatory enzyme type-1 protein phosphatase (PP 1) have been previously identified in insulin-resistant Pima Indians. Because the PP1 catalytic beta-subunit is presumed to be the major isoform in the glycogen-bound PP1 complex, we have selected the structural gene for this subunit (PPP1CB) as a candidate for a detailed genetic analysis. We have determined the exon-intron structure of PPP1CB, and have identified a polymorphic (CA)-repeat marker (D2S1237) at this gene. No sequence abnormalities were detected in PPP1CB by Southern blot analysis or by single-stranded conformational polymorphism analysis of all eight coding exons. Using sib-pair linkage analyses, no evidence for linkage was found between the D2S1237 marker at this locus and fasting insulin, insulin-stimulated glucose uptake in vivo, obesity, or non-insulin-dependent diabetes mellitus. Similarly, we have found no evidence for association of D2S1237 with any of these phenotypes. Based on our data we conclude that the structural gene for the PP1 catalytic beta-subunit does not appear to be a major genetic determinant responsible for the PP1 abnormalities characteristic of insulin resistance in Pima Indians.

AB The role of the trans-acting factor HNF-1 alpha in activating CYP2E1 gene expression was confirmed by transient co-transfection of an HNF-1 alpha expression plasmid and the CYP2E1 promoter fused to the chloramphenicol acetyl transferase (CAT) reporter gene, Only HNF-1 alpha, and not HNF-1 beta, HNF-4, C/EBP alpha, C/EBP beta, or DBP, was able to activate the CYP2E1 promoter, The extent of activation was proportional to the number of copies of the HNF-1 binding sequence upstream of the promoter, Removal or mutation of the HNF-1 binding sequence led to inactivation of the promoter in response to HNF-1 alpha. Gel-shift Western blot analysis using a synthetic HNF-1 binding sequence derived from CYP2E1 and rat liver nuclear extract revealed that the protein-DNA complex obtained with adult rat liver nuclear extract consisted of both HNF-1 alpha and HNF-1 beta proteins, The shifted bands produced by nuclear extracts from adult, where the endogenous CYP2E1 gene is active, and fetal rat liver, where the gene is inactive, were found to migrate differently, suggesting that the population of factors, possibly including different ratios of HNF-1 alpha and HNF-1 beta proteins, map change during development, However, the co-transfection study did not show cooperativity between the two factors, Elements upstream of the HNF-1 binding site were found to affect the activity of the promoter negatively in the transfection assay, DNase I hypersensitive site mapping revealed a hypersensitive site in this inhibiting element in the adult rat liver sample but not in liver from newborn animals.

AB Dehydroepiandrosterone sulfotransferase (DHEA ST) catalyzes the sulfate conjugation of DHEA and other steroids, From 20 to 25% of subjects are included in a subgroup with high levels of hepatic DHEA ST activity, raising the possibility that this enzyme activity might be controlled by a genetic polymorphism, To understand the molecular mechanisms involved in regulating levels of DHEA ST activity in human tissue, we cloned the human DHEA ST gene, STD, STD spans at least 17 kb and is composed of 6 exons and 5 introns, The locations of the splice junctions for several of the introns are identical to those present in the rat phenol or aryl ST gene, the only other cytosolic ST gene for which the entire exon/intron structure has been reported, as well as those present in two partially characterized genes for the rat senescence marker protein, genes that are also thought to encode ST enzymes, The 5'-flanking region of the human STD gene does not contain canonical TATA or CCAAT elements, but this region is capable of promoting transcription of a reporter gene in Hep G2 cells. Molecular cloning and structural characterization of the human STD gene will make it possible to study genetic mechanisms involved in the regulation of DHEA ST activity in human tissue.

AB Since its introduction as an analytical technique capillary electrophoresis has been used for the separation of amino acids and their enantiomers; over 150 studies have been published to date. This review deals with their separation and detection. Amino acids have been resolved using both capillary zone electrophoresis and micellar electrokinetic chromatography. Pre-column derivatization schemes which are employed for the sensitive detection of amino acids are discussed. Criteria for the selection of the pre- or post-column derivatizing agent, chromophore or fluorophore, are presented. Detection systems, direct and indirect, that have been used are given with emphasis on fluorogenic reagents and laser induced fluorescence detection. Also, procedures for the separation of amino acid enantiomers are discussed and illustrated.

AB Direct enantiomeric separations of some racemic amino acids derivatized with 9-fluorenylmethyl chloroformate were obtained using cyclodextrin-modified micellar electrokinetic chromatography (CD/MEKC) with a buffer made up of 5 mM sodium berate (pH 9.2), 150 mM sodium dodecyl sulfate (SDS) and 40 mM gamma-CD. Alternatively, enantiomeric separations were also achieved indirectly using MEKC after pre-column derivatization with (+)-1-(9-fluorenyl) ethyl chloroformate (FLEC). Using either a 10 mM sodium phosphate (pH 6.8) or a 5 mM sodium berate buffer (pH 9.2), each of which contained 25 mM SDS and 10-15% of acetonitrile, FLEC-derivatized serine, alanine, valine. methionine, leucine, phenylalanine, tryptophan, and their diastereomeric pairs were all separated: the L-isomers migrated faster than the corresponding D-isomers. However, when (-)-FLEC was used for derivatization, the D-isomers migrated faster than the corresponding L-isomers. Also, the diastereomers of aspartic acid, glutamic acid, and proline were resolved using a 10 mM sodium citrate buffer (pH 4.4). Using KrF (248 nm) laser-induced fluorescence, the detection limit of (+)-FLEC derivatized DL-amino acids was obtained at the nM level, which was about 100 X more sensitive than UV absorption at 200 nm. Analyte concentrations as low as 3 X 10(-8) M (DL-Val) could be derivatized with (+)-FLEC.

AB Sleep deprivation is associated with poor cognitive ability and impaired physical health, but the ways in which the brain and body become compromised are not understood. In sleep-deprived rats, plasma total T-4 and T-3 concentrations decline progressively to 78% and 47% below baseline values, respectively, brown adipose tissue 5'-deiodinase type II activity increases 100-fold, and serum TSH values are unknown. The progressive decline in plasma thyroid hormones is associated with a deep negative energy balance despite normal or increased food intake and malnutrition-like symptoms that eventuate in hypothermia and lethal systemic infections. The purpose of the present experiment was to evaluate the probable causes of the low plasma total T-4 during sleep deprivation by measuring the free hormone concentration to minimize binding irregularities and by challenging the pituitary-thyroid axis with iv TRH to determine both 1) the pituitary release of TSH and 2) the thyroidal response of free T-4 (FT4) and free T-3 (FT3) release to the TSH increment. Sleep-deprived rats were awake 91% of the total time compared with 63% of the total time in yoked control rats and 50% of the total time during the baseline period. Cage control comparison rats were permitted to sleep normally. Sustained sleep deprivation resulted in a decline from baseline in plasma FT4 of 73 +/- 6% and FT3 of 45 +/- 12%, which were similar to the declines in total hormone concentrations observed previously; nonstimulated TSH was unchanged. In the yoked and cage control groups, FT4 also declined, but much less than that of the sleep-deprived group. The relative changes in free compared with total hormone concentrations over the study were also less parallel than those in the sleep-deprived group. The plasma TSH response to TRH was similar in all groups across experimental days. The plasma FT4 and FT3 concentrations in sleep-deprived rats increased after TRH-stimulated TSH release to an extent comparable to control values. Taken together, low basal FT4 and FT3 hormone concentrations and unchanged TSH and thyroidal responses to TRH suggest a pituitary or hypothalamic contribution to the hypothyroxinemia during sleep deprivation.

AB We established a human bone marrow stromal cell line (Saka) by infecting marrow adherent cells from semisolid marrow cultures with a recombinant simian virus-40 (SV40) virus. The cells expressed SV40 large tumor antigen, had a fibroblast-like shape, and expressed fibronectin and vimentin. They did not contain detectable alkaline phosphatase activity; express myeloid, lymphoid, or factor VIII-associated antigens; or develop adipocyte-like characteristics with dexamethasone treatment. Polymerase chain reaction analysis of Saka cell RNA detected expression of messenger RNAs for interleukin-6 (IL-6), IL-1 beta, granulocyte-macrophage colony-stimulating factor, macrophage colony-stimulating factor, stem cell factor, and the 1,25-dihydroxyvitamin D-3 receptor. Coculture of Saka cells with human marrow mononuclear cells enhanced formation of osteoclast-like multinucleated cells (MNC) in long term human bone marrow cultures. These MNC expressed calcitonin receptors and formed resorption lacunae on dentine. In contrast, coculture of marrow mononuclear cells with other SV40-transformed human marrow stromal cell lines did not increase MNC formation. Conditioned medium from Saka cells or coculture of bone marrow and Saka cells separated by a Millipore membrane did not enhance MNC formation. Addition of a neutralizing antibody to IL-6 or IL-1 beta blocked the effects of Saka cells on MNC formation. These results suggest that marrow stromal cells enhance osteoclast formation in part through direct cell to cell contact and production of IL-6 and/or IL-1 beta.

AB Estrogens have been implicated in the sodium and fluid imbalances associated with the menstrual cycle and late pregnancy. An estrogen-dependent role for renal oxytocin receptors in fluid homeostasis is suggested by the present findings which demonstrate that estradiol benzoate treatment increases the expression of the oxytocin receptor messenger ribonucleic acid and I-125-OTA binding to oxytocin receptors in the renal cortex and medullary collecting ducts of ovariectomized female rats. Moreover, estradiol induced high levels of oxytocin receptor expression in outer stripe proximal tubules of ovariectomized female and adrenalectomized male rats. Proximal tubule induction was inhibited in a dose-dependent manner by the antiestrogen tamoxifen, but cortical expression of oxytocin receptors in macula densa cells was unaffected by tamoxifen. These data demonstrate cell-specific regulation of oxytocin receptor expression in macula densa and proximal tubule cells, and suggest a important role for these receptors in mediating estrogen-induced alterations in renal fluid dynamics by possibly affecting glomerular filtration and water and solute reabsorption during high estrogen states.

AB The weak acid tetrachloroguaiacol (teCG; pK(a) 6.0) is the major chlorinated phenol produced during chlorine bleaching of wood pulp. Upon its release into the environment, it is persistent and markedly bioaccumulated (100- to 1,000-fold). Within the organism (pH similar to 7.4), it should be >95% ionized, making it a likely inhibitor of renal organic anion transport. Its effects on both passive membrane permeability and mediated transport processes were determined in basolateral (BLM) and luminal membrane (BBM) vesicles isolated from the rat kidney cortex. Vesicular solute uptake was measured by the rapid filtration technique at pH 7.5. Passive membrane permeability (assessed by mannitol uptake) was altered only at very high concentrations of teCG (greater than or equal to 1,000 mu M). In contrast, transport of the model organic anion p-aminohippurate (PAH) by BLM vesicles was significantly inhibited by as little as 5 mu M (1.3 mg/L) teCG and totally abolished by 200 mu M. Inhibition was competitive (K-i = 31.3 mu M). Decreasing assay pH diminished inhibition of the PAH uptake, reflecting the reduced concentration of ionized teCG. Other membrane effects were seen at higher teCG concentrations (>100 mu M). The BLM sodium/glutarate cotransport was modestly, but significantly, stimulated by 100 to 500 mu M teCG, whereas BBM sodium/glucose cotransport was inhibited by similar teCG concentrations. Thus, teCG has multiple effects on renal membrane function. However, al environmental levels (0.1 to 30 mu M in plasma), its principal membrane effects would be related to changes in organic anion secretion.

AB In order to explore the potential role of growth hormone (GH) in modulating insulin-like growth factor I (IGF-I) gene expression in the prepubertal rat ovary, female rats were rendered GH deficient by neonatal administration of monosodium glutamate (MSG). One group of rats received vehicle and served as the control. At 21 days of age, MSG-treated rats received either GH or vehicle for 2 weeks. On days 21, 24, 28 and 31 animals were weighed and subsets were sacrificed for liver RNA extraction. The remaining animals were sacrificed at day 35 when livers and ovaries were collected, and serum was obtained for GH determinations. The IGF-I mRNA levels were estimated by Northern blots and corroborated further by slot-blot analysis. The MSG-treated rats had lower body weights (p < 0.01) and GH levels (p < 0.05) than controls. Growth hormone replacement significantly accelerated the weight gain of MSG-treated rats. At day 24 and thereafter, three RNA IGF-I species (7.5, 1.8 and 0.8-1.2 kB) were seen in the liver. in the ovary, at age 35 days, two major IGF-I mRNA species (7.5 and 0.8-1.2 kb) were seen. The MSG treatment consistently reduced the levels of both IGF-I mRNA species in the ovary. Growth hormone administration partially restored their expression, both in the liver and in the ovary. In addition, ovarian type I IGF receptor mRNA levels were increased in the MSG-treated rats when compared to controls. This trend was reversed by GH replacement. In summary, we have found that in prepubertal female rats rendered GH deficient with MSG, ovarian IGF-I gene expression is reduced while type I IGF receptor mRNA levels are increased. These findings are reversed with GH replacement. These results suggest a physiological role for GH in modulating IGF-I and type I IGF receptor genes in the ovary.

AB The OX40 protein is expressed only on activated rat CD4(+) T blasts and is a member of a superfamily of cell surface molecules which includes CD40, CD30, CD95 (Fas), CD27, 4-1BB antigens and the receptors for tumor necrosis factor (TNF) and nerve growth factor (NGF). The proteins of this group are related to each other by having three to six repeats of a cysteine-rich sequence in their extracellular domains. Members of this family of receptors have also been shown to bind to ligands which are structurally related to TNF.
The mouse homologue of the rat OX40 protein was cloned at the cDNA and genomic levels. The gene structure shows that there are several intron/exon borders shared between OX40 and CD27, CD40,TNF receptor type I, CD95 and 4-1BB genes. This group of genes is less closely related structurally to the gene structure of the NGF receptor. The gene encoding murine OX40 has been placed on mouse chromosome 4, in an area which contains the genes for TNF receptor type II and 4-1BB, and is syntenic with a region of human chromosome 1 which contains human TNF receptor type II, OX40, and CD30 genes.

AB Two classes of protein tyrosine kinases (PTK) are utilized by the T cell antigen receptor (TcR)/CD3 complex for initiation of the signaling cascade, the Src-family PTK p56(lck) and p59(fyn), and the Syk-family PTK p70(zap) and p72(syk). In addition, the CD45 phosphotyrosine phosphatase (PTPase) is required for the induction of tyrosine phosphorylation by the TcR/CD3, presumably by positively regulating Src-family PTK. Here we report that CD45 also regulates the Syk-family PTK p70(zap) (or ZAP-70). In CD45-negative T cells, p70(zap) was constitutively phosphorylated on tyrosine and co-immunoprecipitated with the TcR-zeta chain. In resting wild-type CD45-positive cells, p70(zap) was mainly unphosphorylated, but it was rapidly phosphorylated on tyrosine upon treatment of the cells with anti-CD3 or PTPase inhibitors. Finally, p70(zap) co-distributed with CD45 in intact T cells, and tyrosine phosphorylated p70(zap) was dephosphorylated by CD45 in vitro. These findings suggest that CD45 plays an important role, direct or indirect, in the regulation of p70(zap) and its function in TcR/CD3 signaling.

AB The records of 18 patients with intractable partial seizures who were observed on an in-patient epilepsy unit during single drug treatment with carbamezepine (CBZ) or phenytoin (PHT) and during combination therapy with both drugs were evaluated retrospectively. Seizure frequency was significantly lower during combination therapy (p < 0.01) and toxicity, as measured by an eight point objective scale, did not increase significantly (p > 0.10). In addition subjective signs of clinical toxicity (e.g. nausea, ataxia, etc.) increased only slightly during combination versus monotherapy. These findings were consistently seen whether the data were evaluated in total (i.e. treatment periods at least 7 weeks) or evaluated by using standardized 35 day treatment periods. In the absence of a blinded clinical trial evaluating PHT/CBZ combination, these findings support consideration of this combination in intractable patients who have failed rigorously administered monotherapy trials, recognizing however that only a small, percentage of patients will improve on combination therapy.

AB tsJT60 is a temperature-sensitive (ts) mutant of the cell cycle isolated from a rat cell line, It does not enter the cell cycle from the G(0) phase at a nonpermissive temperature (40 degrees C) but proliferates normally in log phase at both permissive (34 degrees C) and nonpermissive temperatures (G(0)-specific ts mutant), Here we examined whether tsJT60 fails to downregulate growth arrest-specific genes after growth stimulation from G(0) phase at 40 degrees C, Among growth arrest-specific genes examined, an expression of gadd153, which decreased after serum stimulation at 34 degrees C as expected, increased markedly at 40 degrees C. It is plausible to assume that induction of gadd153 at 40 degrees C is correlated with inability of tsJT60 to enter S phase from G(0) phase at 40 degrees C, because it also occurred in tsJT366 (another ts mutant clone in the same complementation group) but did not occur in parental 3Y1 and in other ts mutant lines of different complementation groups, However, gadd153 was also induced after the temperature upshift in tsJT60 cells growing in log phase or progressing S phase.

AB Cellular responses following DNA damage are ubiquitous in the biological world. In response to DNA damage, cell cycle checkpoints are activated, which delay cell cycle progression and most likely serve to allow time for repair. One important checkpoint in mammalian cells, activated in the G(1) phase of the cell cycle, is dependent on the p53 tumor suppressor gene product. While p53 is responsible for inducing G(1) arrest, the product of the MDM2 gene is believed to alleviate the arrest, allowing continuation of the cell cycle after a transient delay. Inasmuch as MDM2 and WAF1/CTP1 are transactivated by p53, while MDM2 binds to and modulates the activity of p53, a ''feedback loop'' is thus created. This pathway has been highly conserved in mammalian cells, but its presence outside of vertebrates is unknown. By using human MDM2 and WAF1/CIP1 cDNA probes, and monoclonal antibodies to p53 and Mdm2, we demonstrate in insect cell lines evidence for the existence of p53-, MDM2-, and WAF1/CIP1-like molecules and a p53-regulated pathway following treatment by DNA-damaging agents.

AB Acute graft-vs.-host disease (GVHD) continues to present a barrier to successful allogeneic marrow transplantation. T cell-depletion may prevent severe GVHD but carries an increased risk of graft rejection and relapse posttransplant. Clinical trials have defined the number of lymphocytes associated with sustained engraftment but low risk of significant GVHD (greater than grade I or II skin only) as less than or equal to 10(5)/kg. We examined T cell-depletion resulting from positive selection of CD34(+) hematopoietic cells with a biotinylated monoclonal anti-CD34 antibody and an immunoaffinity column. Eleven patients (six myeloma and five breast cancer) underwent both peripheral blood stem cell (PBSC) collection and marrow harvest prior to autologous transplantation. One PBSC collection and one-third of each marrow underwent column separation. PBSCs were enriched for CD34(+) cells from an initial mean of 1.5 to 53.3%, while marrow went from an initial mean of 2.8 to 65.4%. PBSC were depleted of CD3(+) cells from an initial mean of 9.6 x 10(9) to 8.6 x 10(6). Marrow CD3(+) lymphocyte content was reduced from an initial mean of 5.6 x 10(9) to 8 x 10(5). Since the column permits quantification and salvage of depleted T cells, its use should allow re-addition of T cell-aliquots associated with minimal risk for GVHD and rejection. In addition, since PBSCs were as readily depleted as marrow, allogeneic PBSC transplant may be feasible using this method.

The DNA sequence of the chlamydial gene was determined and the deduced protein sequence compared with other RecA proteins. Ln E. coli recA deletion mutants, the cloned gene conferred moderate recombinational activity as assayed by Hfr matings. The chlamydial recA gene was efficient in repairing alkylated DNA but less so in repairing of UV damage when compared with the E. coli homologue. As detected by an SOS gene fusion, a small but measurable amount of LexA co-cleavage was indicated.

AB Plasma fibrinogen plays a central role in controlling hemostasis. In an earlier report, we found that fibrinogen is oxidized when whole plasma is treated with a metal-catalyzed oxidation system. These studies show that oxidative modification of purified human fibrinogen leads to an exposure-dependent loss of thrombin-induced clot formation. Inhibition of clotting occurred when either metal-catalyzed oxidation or gamma-irradiation was employed to generate oxidizing radicals. Both systems caused covalent modification of fibrinogen, assessed by measuring incorporation of protein carbonyls. Thrombin-catalyzed fibrinopeptide release was normal in irradiated fibrinogen and was only slightly diminished in protein exposed to metal-catalyzed oxidation, indicating that the inhibition of clotting activity was due to impaired fibrin monomer polymerization. Thus, oxidative modification of normal fibrinogen causes dysfibrinogenemia and constitutes a novel mechanism for inhibition of thrombosis.

AB The hypothalamic-pituitary-adrenocortical (HPA) axis and the autonomic nervous system are major effector systems that serve to maintain homeostasis during exposure to stressors. In the past decade, interest in neurochemical regulation and in pathways controlling activation of the HPA axis has focused on catecholamines, which are present in high concentrations in specific brain areas-especially in the hypothalamus. The work described in this review has concentrated on the application of in vivo microdialysis in rat brain regions such as the paraventricular nucleus (PVN) of the hypothalamus, the central nucleus of the amygdala (ACE), the bed nucleus of the stria terminalis (BNST), and the posterolateral hypothalamus in order to examine aspects of catecholaminergic function and relationships between altered catecholaminergic function and the HPA axis and sympathoadrenal system activation in stress. Exposure of animals to immobilization (IMMO) markedly and rapidly increases rates of synthesis, release, and metabolism of norepinephrine (NE) in all the brain areas mentioned above and supports previous suggestions that in the PVN NE stimulates release of corticotropin-releasing hormone (CRH). The role of NE in the ACE and the BNST and most other areas possessing noradrenergic innervation remains unclear. Studies involving lower brainstem hemisections show that noradrenergic terminals in the PVN are derived mainly from medullary catecholaminergic groups rather than from the locus ceruleus, which is the main source of NE in the brain. Moreover, the medullary catecholaminergic groups contribute substantially to IMMO-induced noradrenergic activation in the PVN. Data obtained from adrenalectomized rats, with or without glucocorticoid replacement, and from hypercortisolemic rats suggest that glucocorticoids feedback to inhibit CRH release in the PVN, via attenuation of noradrenergic activation. Results from rats exposed to different stressors have indicated substantial differences among stressors in eliciting PVN noradrenergic responses as well as of responses of the HPA, sympathoneural, and adrenomedullary systems. Finally, involvement of other areas that participate in the regulation of the HPA axis such as the ACE, the BNST, and the hippocampus and the importance of stress-induced changes in expression of immediate early genes such as c-fos are discussed.

AB The potential reproductive toxicity of a mixture of 25 chemicals (MIX) formulated to simulate contaminated groundwater supplies near hazardous waste dumps was evaluated in CD-1 Swiss mice and Sprague-Dawley rats using the reproductive assessment by continuous breeding protocol. Male and female mice and rats were exposed to MIX in the drinking water at concentrations of 1, 5, and 10% of a technically achievable stock solution. For mice, body weight and feed consumption were not affected by MIX but water consumption was decreased for both the 5 and 10% MIX groups in both F-0 and F-1 animals. For F-0 mice, the number of live pups/litter was decreased at 10% MIX and the number of females/litter was decreased 10 and 17% at the mid and high MIX dose, respectively. Vaginal cytology was normal, as were testis weight and testicular spermatid head count. For F-1 mice, fertility was unaffected, but there was a decreased number of female pups/litter (19%) and a decreased adjusted live pup weight at 10% MIX. At necropsy, cauda epididymal sperm concentration and spermatid head count were reduced (20%) in the presence of normal testis, epididymis, prostate, seminal vesicle, liver, and kidney/adrenal weight. Female estrous cyclicity was altered at 5 and 10% MIX with normal kidney/adrenal, uterus, and ovary/oviduct weight. For rats, F-0 body weight and feed consumption were not affected by MIX but water consumption was decreased 10, 30, and 40% in the low-, medium-, and high-dose MIX groups, respectively, and 39% in the high-dose MIX F-1 animals. Rat fertility was normal but there was a decreased number of male pups/litter (11%) and a decreased live pup weight (6%) at 10% MIX. Male and female (F-1) pup weights were decreased on Postnatal Days 0, 4, 7, 14, and 21 (10% MIX) and remained lower through necropsy on Day 120 +/- 10. F-1 fertility was normal but F-2 pup weights were decreased (10% MIX). At necropsy, F-1 (10% MIX) male body weight was decreased 16% and relative kidney, testis, epididymis, and prostate weights were increased in the presence of normal sperm concentration percentage motile sperm and percentage abnormal sperm. Estrous cyclicity was normal as were kidney/adrenal and ovary weight while female liver weight was reduced 14%. In summary, a ''cocktail'' of 25 chemicals commonly found in contaminated groundwater at or near hazardous waste sites was administered in drinking water at doses which resulted in severely decreased water consumption in both mice and rats. Despite the presence, albeit at relatively low concentrations, of many known reproductive toxicants including cadmium, mercury, lead, chloroform, di(2-ethylhexyl)phthalate, and methylene chloride, only minimal reproductive effects were observed in F-0 and F-1 mice and rats.

AB Background/Aims: It has been reported that hepatic iron concentration (HIC) may influence response to therapy in chronic viral hepatitis, The aim of this study was to determine the relationship between HIC and response to interferon alfa therapy in patients with chronic hepatitis C. Methods: HIC was measured in liver biopsy specimens from 58 patients with chronic hepatitis C treated at three centers. Three patients had mild chronic hepatitis C, 35 had moderate to severe chronic hepatitis C, and 20 had active cirrhosis. Serum ferritin levels were measured in 51 of these 58 patients. Response to therapy was defined as normalization of alanine aminotransferase levels at the end of treatment. Results:Twenty-four patients (41%) responded to therapy. HICs were generally within the normal range (<1500 mu g/g). The mean HIC in nonresponders (860 +/- 100 mu g/g; range, 116-2296 mu g/g) was significantly higher than in responders (548 +/- 85 mu g/ g; range, 29-1870 mu g/g) (P < 0.05). Eighty-eight percent of patients with an HIC of >1100 mu g/g and 87% of patients with an elevated serum ferritin concentration did not respond to interferon alfa therapy. Conclusions: HIC seems to influence response to interferon alfa therapy among patients with chronic hepatitis C. A subgroup of patients with chronic hepatitis C has been identified for which an HIC of >1100 mu g/g predicted nonresponse in 88% of patients.

AB To examine the relationship between replication timing and differential gene transcription in tissue-specific and imprinted settings we have studied the replication timing properties of the human Prader-Willi syndrome (PWS) region on human chromosome 15q11-13. Interphase fluorescence in situ hybridization with an overlapping series of cosmid clones was used to map a PWS replication timing domain to a 500- to 650-kb region that includes the SNRPN gene. This PWS domain replicates late in lymphocytes but predominantly early in neuroblasts, with replication asynchrony observed in both tissues, and appears to colocalize with a genetically imprinted transcription domain showing prominent expression in the brain. A 5- to 30-kb deletion in the 5' region of SNRPN results in the loss of late replication control of this domain in lymphocytes when the deleted chromosome is inherited paternally. This potential allele-specific replication timing control region also appears to colocalize with a putative imprinting control region that has been shown previously to abolish the expression of three imprinted transcripts in this same region.

AB By crossing mice that carry a null allele of p53 with transgenic mice that develop mammary adenocarcinomas under the influence of a Wnt-1 transgene, we have studied the consequences of p53 deficiency in mammary gland neoplasia. In Wnt-1 transgenic mice homozygous for the p53 null allele, tumors appear at an earlier age than in animals heterozygous or wild-type at the p53 locus. About half of the tumors arising in p53 heterozygotes exhibit loss of the normal p53 allele, implying selection for p53-deficient cells. Mammary tumors lacking p53 display less fibrotic histopathology and increased genomic instability with aneuploidy, amplifications, and deletions, as detected by karyotype analysis and comparative genomic hybridization. In one tumor, the amplified region of chromosome 7 had an ectopically expressed int-2/FGF3 proto-oncogene, a gene known to cooperate with Wnt-1 in the production of mammary tumors. These findings favor a model in which p53 deficiency relaxes normal restraints on chromosomal number and organization during tumorigenesis.

AB 6-O-alpha- and beta-D-glucopyranosylmorphine and 6-O-beta-D-glucopyranosylcodeine have been prepared by condensations of 2,3,4,6-tetra-O-acyl-alpha-D-glucopyranosyl bromides with 3-O-acetylmorphine and codeine, respectively, followed by deprotection. Depending upon the method of condensation, variable amounts of orthoesters were found among the final products of condensation together with the desired glycosides. Highest yields of glycosides were obtained when 2,3,4,6-tetra-O-benzoyl-alpha-D-glucopyranosyl bromide was the glycosyl donor, and when the condensation was promoted with silver triflate in the presence of a less than stoichiometric amount of 2,4,6-trimethylpyridine as the acid scavenger.

AB Pulsatile secretion of thyrotropin (TSH) is a well characterized phenomenon in the human, yet only limited data are available from animal studies. We propose a combined model of chronic catheterization and suppression of endogenous TSH release in the rat allowing us to apply quantified pulses of different preparations of thyrotropin intravenously with minimal interference with endogenously produced hormone. Sprague-Dawley rats treated with drinking water containing 3,5,3'-triiodothyronine (T3) showed a significant 6-fold decrease of the rat TSH (rTSH) level after four days. Free thyroxine (FT4) levels were 9-fold below unsuppressed levels; FT4 response to exogenous TSH application above this suppressed baseline level was selected as an endpoint. Infusion studies compared pulsatile with continuous TSH administration. A low and a high dose of rTSH and recombinant human TSH (rec-hTSH) were administered. Levels of FT4 were compared after two and four days and responsiveness to a standard high bolus of rTSH 6 h after end of infusion was assessed. With regard to its potency for FT4 release, differences indicating a general trend as to superior efficiency of pulsatile TSH stimulation of the thyroid gland in comparison to continuous stimulation could be observed in all four experiments. More pronounced effects were seen after 2 and 4 days of high rTSH infusion and after 4 days of low rec-hTSH infusion. Comparison of FT4 responses to rTSH boli showed a 2- and 6-fold higher response in the pulsatile group compared to the continuous group after low and high rTSH infusion, respectively. This was not observed in the animals receiving low rec-hTSH infusion. However, after high rec-hTSH infusion, a bolus following pulsatile infusion resulted in a lesser decrease in FT4 levels in comparison to that after continuous application. Our data suggest that pulsatile application of TSH might be of superior efficiency with regard to in vivo stimulation of thyroid hormone secretion, hence suggesting an underlying physiological significance of this release pattern.

AB Communication between the central components of the stress response and the immune system plays an important role in susceptibility to inflammatory disease. This communication occurs through hormonal and neuronal mechanisms. Hormonal mechanisms involve activation of the hypothalamic-pituitary-adrenal (HPA) axis by immune system products, e.g. cytokines. The stimulated HPA axis regulates immune responses through the immunosuppressive effects of glucocorticoids. Neuronal mechanisms include direct innervation of immune organs. Cytokine activation of the HPA axis and the resultant glucocorticoid-induced suppression of immune and inflammatory responses represent an important mechanism whereby the central stress response modulates peripheral inflammation. Interruption of this communication is associated with exacerbation of inflammatory disease. Conversely, intracerebroventricular transplantation of hypothalamic tissue from inflammatory resistant rats into susceptible rats reduces peripheral inflammation by more than 85%.

AB A stressor above a threshold magnitude, or multiple stressors applied simultaneously, cause an organism to alter its behaviour and physiology, with the aim of maintaining homeostasis. The adaptive changes that occur are coordinated and mediated by the stress system in the central nervous system (which includes corticotrophin-releasing hormone and noradrenergic neurons in the hypothalamus and brainstem, respectively), and its peripheral limbs, the hypothalamic-pituitary-adrenal axis and the autonomic (sympathetic) system. Controlled or self-driven challenges to homeostasis and a normally functioning stress system are crucial for normal development and preservation of self and species. In childhood and adolescence, appropriately functioning neuroendocrine responses to stressors are necessary to allow growth and psychosexual maturation to progress normally. Maladaptive neuroendocrine responses, i.e. dysregulation of the stress system, may lead to disturbances in growth and development and cause psychiatric, endocrine/metabolic and/or autoimmune diseases or vulnerability to such diseases, not only during childhood and adolescence, but also in adulthood.

AB We report on an in vivo delivery system that attenuates the growth, in nude mice, of a malignant human breast cancer cell line containing a p53 mutation. Nude mice, inoculated with breast carcinoma cells, were injected every 10-12 days with a liposome-p53 complex via the tail vein. A significant reduction of greater than 60% in primary tumor volume was observed as compared to the control groups. Furthermore, when individual growth patterns of the tumors were assessed, we found that primary tumor size regressed in the majority of p53-treated animals (8/15), whereas only one tumor in the control groups (1/22) regressed. The eight tumors that regressed with the liposome-p53 complex showed no evidence of relapse for 1 month after the cessation of treatment. We also determined that the administration of the liposome-p53 complex reduced the incidence of metastases. The MDA-MB-435 tumor cells, transduced with the lacZ gene, facilitated quantitation of beta-galactosidase activity and tumor burden in the lungs. The number of metastatic cells in the lung was significantly lower in the p53-treated group (0.53 +/- 0.43 x 10(6), p < 0.01) than in either the vector-treated (8.1 +/- 3.7 x 10(6)) or untreated control groups (15.8 +/- 5.9 x 10(6)). Thus, systemic administration of the liposome-p53 complex reduced not only the size of the primary tumors but, more importantly, prevented the relapse and metastases of these tumors.

We have undertaken to saturate the A-T region with highly polymorphic microsatellite markers. To this end, we have identified seven new polymorphic CA-repeats in this region, and have mapped to it five new markers generated by Genethon and the Cooperative Human Linkage Center. These markers are in addition to 12 others that we have previously mapped or generated at the A-T locus. All 24 markers have been integrated into a high-density microsatellite map spanning some 6 Mb DNA. This map, which contains the A-T locus and flanking sequences, allows the construction of extensive, highly informative haplotypes.

AB C2H2-type zinc finger genes comprise one of the largest gene families in the human genome, These proteins are involved in genetic regulation and development and are quite conserved throughout evolution. The finger domains commonly contain the small linker peptide TGEKP between same finger units, Here, we report the isolation of 133 human zinc finger cDNAs, of which 118 are novel, These clones were isolated from human brain cDNA libraries using oligonucleotide hybridization followed by expressed sequence tag (EST) analysis, sequencing from the conserved linker region using degenerate oligonucleotide primers, This directed partial sequencing approach to cDNA isolation and characterization, signature sequencing, combines the speed of EST automatic sequencing with the focus of specific cDNA family analysis, Signature sequencing minimizes the generation of less informative random EST sequences and provides a unique relative position for sequence comparison. We also show that there is an even distribution of these RNAs from this brain cDNA library, and that these cDNAs contain N-terminal domains found in other zinc finger genes. This rapid focused sequencing approach should be applicable to any family of cDNAs containing short conserved signature peptide sequences.

AB To understand the molecular bases for cytokine redundancy and pleiotropy, we have compared the Stat proteins activated In peripheral blood lymphocytes (PBLs) by cytokines with shared and distinct actions. Interleukin-2 (IL-2) rapidly activated Stat5 in fresh PBL, and Stat3 and Stat5 in preactivated PBL. IL-7 and IL-15 induced the same complexes as IL-2, a feature explained by the existence of similar tyrosine-phosphorylated motifs in the cytoplasmic domains of IL-PRP and IL-7R that can serve as docking sites for Stat proteins. IL-13 induced the same complexes as IL-4, a finding explained by our studies implicating IL-4R as a shared component of the receptors. These studies demonstrate that a single cytokine can activate different combinations of Stat proteins under different physiological conditions, and also indicate two mechanisms by which distinct cytokines can activate the same Stat protein.

AB The present study has examined the molecular events leading to formation of up dimers in normal murine thymocytes and mature T cells. We demonstrate that TCR assembly proceeds by initial association of TCR alpha with CD3 delta epsilon proteins and by association of ICRP with CD3 gamma epsilon proteins to form alpha delta epsilon and beta gamma epsilon trimers; these trimers then associate to form alpha delta epsilon-beta gamma epsilon complexes, within which alpha-beta disulfide bond formation occurs. We also show that TCR-associated protein (TRAP) associates uniquely with CD3 gamma epsilon pairs and that formation of beta gamma epsilon trimers occurs subsequent to TRAP dissociation. Importantly, we document that the assembly step that is quantitatively limiting in CD4(+)CD8(+) thymocytes is the initial association of TCR alpha with CD3 delta epsilon chains, which appears necessary to protect nascent TCR alpha proteins from accelerated degradation within the ER of immature thymocytes.

AB Differentiation of immature CD4(+)CD8(+) thymocytes into mature CD4(+)CD8(-) and CD4(-)CD8(+) T cells requires that synthesis of one or the other coreceptor molecule be terminated, a process referred to as lineage commitment. The present study has utilized a novel coreceptor reexpression assay to identify lineage commitment in immature thymocytes and has found that the MHC recognition requirements for CD4 commitment and CD8 commitment fundamentally differ from one another. Remarkably, we found that thymocyte commitment to the CD8(+) lineage requires MHC class I-dependent instructional signals, whereas thymocyte commitment to the CD4(+) lineage is MHC independent and may occur by default. In addition, an unanticipated relationship between lineage commitment and surface phenotype has been identified. These results are incompatible with current concepts and require a new perspective on lineage commitment and positive selection, which we refer to as asymmetric commitment.

AB The O-specific antigen in extraintestinal isolates of Escherichia coli is believed to be an important virulence factor. To assess its role in the pathogenic process, proven isogenic derivatives with either a complete (CP921) or nearly complete (CP920) deficiency of the O4 antigen were obtained by TnphoA'1-mediated transposon mutagenesis of an O4/K54/H5 blood isolate (CP9), By utilizing a previously reported isogenic K54 capsule-deficient derivative (CP9.137), additional isogenic derivatives deficient in both the K54 capsular antigen and either all (CP923) or nearly all (CP922) of the O4 antigen were also constructed, These strains and their wild-type parent were evaluated in vitro for serum sensitivity and in vivo by intraperitoneal challenge of outbred mice, The complete or nearly complete loss of the O4 antigen (CP920 and CP921) resulted in only a minor increase in serum sensitivity, In contrast, CP9.137 had a significant increase in serum sensitivity, and CP922 and CP923 were extremely serum sensitive. When tested in vivo, the complete or nearly complete loss of the O4 antigen resulted in a small but significant increase (P less than or equal to 0.05), not the expected decrease, in virulence compared with its wild-type parent. In contrast, CP9.137 and CP922 were significantly less virulent (P 0.05). These studies do not exclude a role for the O4 antigen moiety of lipopolysaccharide in the pathogenesis of extraintestinal E. coli infection; however, they demonstrate that the O4 antigen plays only a minor role in serum resistance in vitro and that its loss does not diminish and perhaps enhances the virulence of CP9 in vivo after intraperitoneal challenge.

AB Using antibodies against homeoprotein XlHbox 1 from Xenopus laevis, we have detected a new embryonic protein with a much larger molecular weight, 115 kDa. Antibodies fractionated according to their affinity for 3 different domains of the XlHbox 1 protein were used to show that this new protein is related to the C-terminal region of XlHbox 1 protein, downstream from the homeodomain. By immunohistochemistry, the protein was shown to be localized in nuclei of embryonic cells. On SDS-polyacrylamide gels, the 115 kDa protein appears as a set of closely spaced bands whose pattern varies with the stage of development and with the parental origin of the embryos. The protein could be extracted from embryos in a multiprotein complex of approximately 600 kDa. In contrast, the 18 and 27 kDa proteins predicted from the sequence of cloned cDNA to be transcribed and translated from the XlHbox 1 gene could not be detected, suggesting that they are rare or unstable in embryos. These data suggest that the new protein is involved in the development of Xenopus embryos, with a function possibly related to that of the homeoprotein XlHbox 1.

ID SEROTONIN ACTIVITY; BULIMIA-NERVOSA
AB On September 27-29, 1993, the Study Group on Anorexia Nervosa (AN): Basic Mechanisms, Clinical Approaches and Treatment met in Geneva, Switzerland to discuss recent progress in research on anorexia nervosa, and to identify directions for future studies. Anorexia nervosa is a disorder of unknown etiology, without a specific curative treatment, affecting mostly individuals in adolescence and early adulthood, with significant morbidity and mortality and having a major impact on psychosocial and vocational development. In anorexia nervosa there are severe disturbances in virtually every endocrine system, such as the hypothalamic-pituitary-adrenal (HPA) axis, the hypothalamic-pituitary-gondal (HPG) axis, the hypothalamic-pituitary-thyroid (HPT) axis, the growth hormone (GH)/somatomedin C (IGF-1) system, and the central and peripheral arginine vasopressin (AVP) systems. Furthermore, classical neurotransmitter systems, such as the cholinergic noradrenergic, and serotonergic systems, are abnormally regulated in anorexia nervosa. New research data is also emerging on the abnormal regulation of immune function in this disorder. The Study Group concluded that even though several biological systems are abnormally regulated in anorexia nervosa, there is no biological test which is specific enough to make the diagnosis of the disorder. New directions for research in anorexia nervosa are identified and discussed in this report. Finally, the Study Group proposed future meetings to bring together clinical and pre-clinical (pharmacological, biochemical, and molecular) scientists studying topics, such as neuroendocrine function, which are important in the biology of anorexia nervosa.

AB Background. Cancer incidence and mortality were evaluated among 4581 aniline dye production workers in Moscow.
Methods. A historical cohort was assembled and followed-up from 1 January 1975 to 31 December 1989. Moscow district oncologic dispensary registries furnished case ascertainment and employer records provided job exposure data. Expected cancers and deaths were calculated based on gender-, age-, and calendar time-specific incidence and mortality rates for the Moscow general population applied to the cohort's person-years of follow-up. Disease-specific standardized mortality and incidence values were derived from ratios of observed to expected cancers.
Results. Men experienced elevated total cancer mortality (standardized mortality ratio [SMR] = 125; 95% Cl : 110-142) and urinary bladder cancer mortality (SMR = 279; 95% Cl : 192-391), and increased all malignancy (standardized incidence ratio [SIR] = 142; 95% Cl : 125-160), oesophageal (SIR = 203; 95% Cl : 108-347), respiratory tract (SIR = 154; 95% Cl : 120-194) and bladder (SIR = 394; 95% Cl : 268-559) cancer incidence. Women had elevated oesophageal (SMR = 313; 95% Cl : 124-664) and bladder (SMR = 311; 95% Cl : 149-571) cancer mortality and elevated all malignancy (SIR = 124; 95% Cl : 106-144), oesophageal (SIR = 348; 95% Cl : 140-719), and bladder (SIR = 861; 95% Cl : 458-8002) cancer incidence. Bladder cancer rate increased with employment duration and younger age first hired. Rate estimates were highest among beta-naphthylamine exposed workers but was also increased among workers with other chemical exposures. A cancer prevention and control effort that limited benzidine exposure to less than or equal to 3 years was apparently unsuccessful as indicated by a significant excess of bladder cancer (SIR = 1773; 95% Cl : 356-5180) among these workers.
Conclusion. Relative rates of oesophageal, lung, and stomach cancer were also elevated among all workers, but did not increase with total years worked, age first hired, or year first hired, suggesting a non-occupational aetiology.

AB Malignant astrocytomas are highly invasive neoplasms which infiltrate diffusely into regions of normal brain. As evidence to support one mechanism by which tumor cells are known to invade, we have previously shown that astrocytoma cell lines secrete a variety of matrix metalloproteinases (MMPs) and metalloproteinase inhibitors (Apodaca et al: Cancer Res 50: 2322-2329, 1990). In the present study we determined the expression of tissue inhibitor of metalloproteinase (TIMP)-1, TIMP-2, 72-kDa and 92-kDa type IV collagenase transcripts among human astrocytoma cell lines. In addition, we sought to correlate MMP and TIMP transcript levels with astrocytoma invasiveness. RNA from seven well characterized human astrocytoma cell lines was extracted before and after phorbol ester treatment and Northern blot analyses were performed using cDNA probes for the MMPs and TIMPs. All astrocytoma cell lines and normal human leptomeningeal cells were tested for their relative invasive potential using an in vitro invasion assay. There was variable expression of MMP and TIMP transcripts among astrocytoma cell lines. SF-188 was the only cell line to demonstrate a relative abundance of 72- and 92-kDa type IV collagenase transcripts over TIMP-1 and TIMP-2 transcript levels. Interestingly, this cell line was the most highly invasive in the in vitro invasion assay system. U 343 MG-A demonstrated relative abundance of TIMP-1 and -2 transcripts over 72- and 92-kDa type IV collagenase transcripts and was the least invasive cell line. Prior treatment of astrocytoma cell lines with phorbol ester upregulated TIMP-1 and 92-kDa type IV collagenase transcripts, but not TIMP-2 and 72-kDa type IV collagenase transcripts. We conclude that there is only partial correlation between MMP and TIMP transcript levels and in vitro cell invasiveness among the astrocytoma cell lines studied. Our analysis has led to the identification of an astrocytoma cell line, SF-188, which appears to overexpress the 72-kDa and 92-kDa type IV collagenase transcripts relative to low level TIMP-1 and TIMP-2 transcripts. This particular cell line will continue to be of considerable value in dissecting some of the molecular mechanisms involved in astrocytoma cell invasion.

AB Spiroplasma strain MQ-4(T) (T = type strain), which was isolated from the hemolymph of the vespid wasp Monobia quadridens, was serologically distinct from other spiroplasma species, groups, putative groups, and subgroups. Each strain MQ-4(T) cell was helical and motile and was surrounded by a single cytoplasmic membrane; there was no evidence of a cell wall. The strain grew well in 1% serum fraction medium, as well as in SM-1, M1D, and SP-4 liquid media, under both aerobic and anaerobic conditions. Strain MQ-4(T) grew at temperatures ranging from 10 to 41 degrees C hut did not grow at 43 degrees C. The strain grew optimally at 37 degrees C with a doubling time of 0.6 h, the shortest doubling time recorded fog any spiroplasma. Strain MQ-4(T) catabolized glucose and arginine but did not hydrolyze urea. The guanine-plus-cytosine content of the DNA was about 27.5 +/- 1 mol%. The genome size was 1,480 kbp (940 MDa). Strain MQ-4 (= ATCC 35262) designated the type strain of a new species, Spiroplasma velocicrescens.

AB Purpose. Mice of the H-2(b), H-2(k), and H-2(r) haplotypes develop experimental autoimmune uveoretinitis (EAU) after immunization with interphotoreceptor retinoid-binding protein (IRBP) of bovine or monkey origin. The purpose of this study was to identify putative pathogenic epitope(s) of IRBP and to establish their immunodominance within the IRBP molecule.
Methods. Overlapping 20-amino acid peptides, spanning the entire human IRBP molecule, were synthesized and used to immunize C57BL/10 (H-2(b)), B10.BR (H-2(k)), and B10.RIII (H-2(r)) mice. Bovine IRBP was used as a positive control. Experimental autoimmune uveoretinitis was examined by histopathology 21 days after immunization. Immunologic responses were assessed by delayed-type hypersensitivity (DH) and lymphocyte proliferation assays.
Results. Peptide 161-180, spanning the sequence SGIPYIISYLHPGNTILHVD, was found to be highly pathogenic for B10.RIII mice but not for the other strains. A dose-response curve showed that peptide 161-180 was maximally pathogenic at 50 mu g, but incidence and scores were reduced at 10 mu g. The truncated 13-mer 165-177 was also highly pathogenic (100 to 200 mu g), suggesting that it contained the pathogenic epitope. Mice immunized with the peptide, or with whole IRBP, had positive DH and lymphocyte responses to the immunizing as well as to the reciprocal antigen. A cell line derived to peptide 161-180 was also pathogenic for B10.RIII mice after adoptive transfer and responded (proliferation) to native IRBP.
Conclusions. High incidence and high severity scores, as well as immunologic cross-recognition of peptide 161-180 and native IRBP in vivo and in vitro, suggest that this peptide contains a major epitope recognized as pathogenic by B10.RIII mice.

AB The associate learning subtest from the Wechsler Memory Scale; Benton's Visual Retention test and a Controlled Word Association Task (FAS) were administered to a random sample of normal, healthy individuals whose age ranged from 20 to 79 years, recruited within the Italian peninsula. The neuropsychological examination took place on a mobile unit and the tests were given by the same team of neuropsychologists to reduce variability among examiners. The Research Project was known as Progetto Memoria. Corrections to the scores of these tests were calculated for age, sex, and education. These corrected values will allow clinicians to screen for memory impairment with greater precision among normally aging individuals, thus improving differential diagnosis between physiologic and pathologic deterioration of cognitive functions.

AB Temperatures greater than or equal to 42 degrees C, maintained for greater than or equal to 25 min, inactivate approximate to 25% of human immunodeficiency virus (HIV). HIV-infected T cells are more sensitive to heat than healthy lymphocytes, and susceptibility increases when the cells are presensitized by exposure to tumor necrosis factor. Thus, induction of a whole-body hyperthermia or hyperthermia specifically limited to tissues having a high viral load is a potential antiviral therapy for acquired immunodeficiency syndrome (AIDS). Accordingly, we incorporated therapeutic hyperthermia into an existing mathematical model that evaluates the interaction between HIV and CD4(+) T cells. Given the assumptions and limitations of this model, the results indicate that a daily therapy lowering the population of actively infected cells by 40% or infectious virus by 40% would effectively reverse the depletion of T cells. In contrast, a daily decline of 20% of either actively infected cells or infectious virus would have a marginal effect. However, daily reduction by 20% of both actively infected cells and infectious virus could restore T-cell numbers, assuming that permanent damage had not been inflicted on the thymus. Since daily treatments would probably be excessively stressful, whole-body hyperthermia seems unlikely to be clinically useful. In contrast, heating directed specifically to areas of viral concentration may be effective and have a suitable risk/benefit ratio.

AB Nitric oxide (NO) inhibits vascular smooth muscle cell (SMC) growth in vitro. To determine the effects of release rate and exposure time on SMC growth inhibition by NO, we compared the activities of five NO donors that generate NO with half-lives of 2 min (DEA/NO, Et(2)N[N2O2]Na), 15 min (PAPA/NO, CH3(CH2)(2)N[N2O2](-)(CH2)(3)NH3+), 39 min, (SPER/NO, H2N(CH2)(3)NH2+(CH2)(4)N[N2O2](-)(CH2)(3)NH2), 3 h (DPTA/NO, H2N(CH2)(3)N[N2O2](-)(CH2)(3)NH3+), and 20 h (DETA/NO, H2N(CH2)(2)N[N2O2](-)(CH2)(2)NH3+). After 22-h treatment, rat aorta SMC (RA-SMC) DNA synthesis was inhibited with IC,, values of 180, 60, and 40 mu M for SPER/NO, DPTA/NO, and DETA/NO, respectively. DEA/NO and PAPA/NO did not inhibit DNA synthesis significantly at any concentration tested (20-500 mu M). The inhibitory effect of NO on RA-SMC DNA synthesis was thus greatest when a given molar dose of NO was delivered slowly throughout the 22-h period. The antiproliferative effect of DETA/NO was confirmed by measurement of cell numbers for 7 days. When RA-SMC were treated with 500 mu M DETA/NO on days 1, 3, and 5, growth was completely suppressed. Cell viability was >95%, confirming that DETA/NO was not cytotoxic. The results suggest that NO donors may be useful inhibitors of intimal hyperplasia and restenosis after vascular injury such as balloon angioplasty.

AB Monocyte-derived macrophages accumulate and process cholesterol in atherosclerotic lesions. Because of the importance of this process, we examined the interaction of cholesterol crystals and acetylated low density lipoprotein (AcLDL) with human monocyte-macrophages in a combined chemical and morphological study. These two forms of cholesterol induced extensive compartmentalization of the macrophage cytoplasm, Unexpectedly, the compartments maintained a physical connection to the extracellular space as demonstrated with ruthenium red staining. The compartments formed through invagination of the top surface of the macrophage plasma membrane. Some cholesterol crystals and AcLDL were sequestered within these surface-connected compartments for up to five days in the case of the crystals and for one day in the case of AcLDL.
Pulse-chase studies of fractionated macrophages indicated that [H-3]cholesterol redistributed from the surface-connected compartments into lysosomes (where the cholesterol remained unesterified) and into lipid droplets (where the cholesterol was stored as cholesteryl ester). Intracellular uptake and esterification of cholesterol was blocked by cytochalasin D. However, once cholesterol was sequestered in the surface-connected compartments, subsequent esterification of the cholesterol could not be inhibited by cytochalasin D. Apolipoprotein E was localized within the surface-connected compartments by immunogold labeling suggesting a possible function for this protein in the processing of lipid taken up through the sequestration pathway.
Removal of microcrystalline cholesterol from the medium resulted in release of most of the accumulated cholesterol microcrystals from the macrophages, as well as disappearance of the surface-connected compartments. Thus, sequestration is a novel endocytic mechanism in which endocytic compartments remain connected to the extracellular space. This differs from phagocytosis where endocytic vacuoles rapidly pinch off from the plasma membrane. Sequestration provides a means for macrophages to remove substances from the extracellular space and later release them.

AB Fibroblast growth factor receptors (FGFRs) are encoded by at least four distinct highly conserved genes, and alternative splicing generates multiple gene products. The close relationship among different FGFRs has greatly increased the difficulty in generating specific immunochemical probes. As an alternative strategy, we constructed a fusion protein comprising keratinocyte growth factor (KGF) and an IgG(1) Fc domain (HFc). The chimeric molecule was efficiently secreted from transfectants as a disulfide-linked dimer that bound KGFRs with high affinity. Moreover, the KGFHFc, like native KGF, induced DNA synthesis by epithelial cells implying normal functional receptor activation, Because it retained the convenient detection properties of an immunoglobulin, it was possible to use the KGF-HFc in ligand-mediated histochemical analysis of KGFRs. Flow cytometry revealed KGE-HFc chimera detection of the KGFR, an alternative FGFR2 product, but not FGFR1 (flg) or FGFR2 (bek). Histochemical analysis of normal skin demonstrated the specific localization of KGFRs within the spinous layer, a zone of epithelial cell differentiation. KGFRs were also localized to epithelial cells within a specific region of the hair follicle, and they were not detectable in cells of the sweat gland. Tissue sections of soft palate and tonsil, two examples of nonkeratinizing epithelium, revealed staining of stratum spinosum and some staining of the basal cell layer as well. Neither salivary gland epithelium nor lymphoid cells were positive. The ciliated epithelium of the trachea exhibited KGFR expression in intermediate and basal cell layers. In striking contrast to the normal pattern of staining in the adjacent epithelium, a squamous cell carcinoma of skin lacked detectable KGFRs. Our present findings suggest that growth factor-Ig fusion proteins may be generally applicable in ligand-mediated histochemical detection and localization of growth factor receptors.

AB Previously, we have reported a decrease in the binding of a cAMP analog to the regulatory subunits of cAMP-dependent protein kinase (cAMP-PK), as well as a decrease in cAMP-PK activities, in psoriatic cells. Retinoic acid (RA) treatment of these cells can induce an increase in cAMP-PK toward normal levels. To better define the effect of retinoic acid on the cAMP-PK system in psoriatic fibroblasts, Western blot analysis using an RII alpha specific antibody and in vivo phosphorylation experiments were carried out to determine possible changes in the RII regulatory subunit. Our results indicate a decrease in the binding of the cAMP analog 8-azido-[P-32]-cAMP with no change in the level of RII protein in psoriatic fibroblasts. In addition, by two-dimensional gel electrophoresis we observed the presence oi a phosphorylated Form of RII unique to psoriatic cells which is suppressed by RA treatment. This study suggests an altered posttranslational modification of the cAMP-PKII in psoriatic fibroblasts which can be reversed by exposure of these cells to RA. (C) 1995 Wiley-Liss, Inc.

AB The role of intracellular Ca2+ in the regulation of Ca2+-induced terminal differentiation of mouse keratinocytes was investigated using the intracellular Ca2+ chelator 1,2-bis(o-aminophenoxy)-ethane-N,N,N',N'-tetraacetic acid (BAPTA). A cell permeable acetoxymethyl (AM) ester derivative BAPTA (BAPTA/AM) was loaded into primary mouse keratinocytes in 0.05 mM Ca2+ medium, and then the cells were induced to differentiate by medium containing 0.12 or 0.5 mM Ca2+ Intracellular BAPTA loaded by BAPTA/AM (15-30 mu M) inhibited the expression of epidermal differentiation-specific proteins keratin 1 (K1), keratin 10(K10), filaggrin and loricrin as detected by immunoblotting. The differentiation-associated redistribution of E-cadherin on the cell membrane was delayed but not inhibited as determined by immunofluorescence. BAPTA also inhibited the expression of K1, K10 and loricrin mRNA. Furthermore, BAPTA prevented the decrease in DNA synthesis induced by 0.12 and 0.5 mM Ca2+, indicating the drug was inhibiting differentiation but was not toxic to keratinocytes. To evaluate the influence of BAPTA on intracellular Ca2+, the concentration of intracellular free Ca2+ (Ca-i) in BAPTA-loaded keratinocytes was examined by digital image analysis using the Ca2+-sensitive fluorescent probe fura-2, and Ca2+ influx was measured by Ca-45(2+) uptake studies. Increase in extracellular Ca2+ (Ca-o) in the culture medium of keratinocytes caused a sustained increase in both Ca-i and Ca2+ localized to ionomycin-sensitive intracellular stores in keratinocytes. BAPTA lowered basal Ca-i concentration and prevented the Ca-i increase. After 12 hours of BAPTA treatment, the basal level of Ca-i returned to the control value, but the Ca2+ localized in intracellular stores was substantially decreased. Ca-45(2+) uptake was initially (within 30 min) increased in BAPTA-loaded cells. However, the total Ca-45(2+) accumulation over 24 hours in BAPTA-loaded cells remained unchanged from control values. These results indicate that keratinocytes can maintain Ca-i and total cellular Ca2+ content in the presence of increased amount of intracellular Ca2+ buffer (e.g., BAPTA) by depleting intracellular Ca2+ stores over a long period. The inhibition by BAPTA of keratinocyte differentiation marker expression may result from depletion of the Ca2+-stores since this is the major change in intracellular Ca2+ detected at the time keratinocytes express the differentiation markers. In contrast, the redistribution of E-cadherin on the cell membrane may be more directly associated with Ca-i change. (C) 1995 Wiley-Liss, Inc.

AB The crystal and molecular structure of pindolol, 1-(1H indol-4-yloxy)-3-[(1-methylethyl)amino]-2-propanol, has been determined by direct methods. Crystals are tetragonal, P (4) over bar 2(1)c, a = b = 15.809(4), c = 11.246(2) Angstrom, Z = 8, D-c = 1.174 mg m(-3). The final R-factor for 2271 reflections with I > 2 sigma(I) is 0.038. Refinement by full-matrix least-squares on F-2 also enabled the absolute configuration of the structure to be established. The molecule is essentially planar, including much of the side-chain which is stabilized by the existence of two intramolecular H-bonds, between the ethyl oxygen and OH group, and between the OH and side-chain amide groups, respectively. The crystal structure is formed by three intermolecular hydrogen bonds including two side-chain-sidechain interactions, between ethyl oxygen to amide and OH to amide, and an interaction between the side-chain OH to indole NH.

AB The tripeptide hormone, TRH, is metabolized by three enzymes, the most specific of which is pyroglutamyl peptide hydrolase-II (also termed thyroliberinase), a metalloenzyme present in serum and brain. Because pyroglutamyl peptidase-II activity in rat serum is regulated by thyroid hormone levels, we tested the hypothesis that this activity is similarly altered in humans. We studied serum pyroglutamyl peptidase-II activity in 6 patients with hyperthyroidism, 18 patients with hypothyroidism, and 31 euthyroid, normal weight volunteers. Because TRH [or its metabolite cyclo(His-Pro)] is believed to be an important hormone regulating appetite and metabolism, we also evaluated pyroglutamyl peptidase-II activity in 27 euthyroid patients with obesity. Serum pyroglutamyl peptidase-II activity was elevated in patients with hypothyroidism (mean +/- SEM, 33.9 +/- 3.7 nmol/mL.h) compared to that in euthyroid, normal weight volunteers (24.5 +/- 2.8 nmol/mL.h; P < 0.05), but not that in patients with hyperthyroidism (28.3 +/- 4.1 nmol/mL.h; P = NS). Euthyroid obese patients had the highest pyroglutamyl peptidase-II activity (43.6 +/- 2.8 nmol/mL.h; P < 0.0001 vs. normal weight volunteers). Pyroglutamyl peptidase-II activity was positively correlated with body mass index (r(2) = 0.30; P < 0.0001). After correction for body mass index, there were no difference in pyroglutamyl peptidase-II activity in hypothyroid, hyperthyroid, and euthyroid individuals. We conclude that serum pyroglutamyl peptidase-II activity is regulated by, or regulates, body weight.

AB A single point mutation that encodes an aspartic acid (Asp(578)) to glycine substitution in the LH/CG receptor (LH/CGR) gene, D578G, was recently found in American patients with familial male-limited precocious puberty and in a Japanese patient with a sporadic form of the disorder. Transfection of the mutant, compared to the wild-type, LH/CGR complementary DNA into COS-7 cells results in higher basal cAMP production, but a normal agonist-induced response; the mutation is, therefore, proposed to constitutively activate Leydig cells and elevate serum testosterone, despite low levels of gonadotropin. In the current study we examined two additional Japanese patients with male-limited precocious puberty without a family history of the disease. We describe a heterozygous cytosine (C) to thymine (T) transition at nucleotide 1715 in both; the mutation encodes an alanine to valine substitution in codon 572 of transmembrane helix 6, A572V. Transfected into COS-7 cells, the A572V mutant exhibited the same constitutively high basal cAMP levels and normal agonist-induced cAMP response as the D578G mutant. We conclude that the constitutively higher cAMP levels caused by the A572V mutation led to Leydig cell activation and male-limited precocious puberty, as in the previously described D578G mutation. As the mother of one of the two patients had the same heterozygous mutation, this patient represents the first recognized case of inherited male-limited precocious puberty in the Japanese population.
The previously described D578G mutant did not increase basal or agonist-induced inositol phosphate production in transfected COS-7 cells, or the number of LH/CGRs or their affinity for LH/CG. In contrast, transfection of the A572V mutation in COS-7 cells exhibited significantly higher inositol phosphate levels basally and at 10(-11) mol/L hCG, but significantly lower inositol phosphate levels at 10(-7) mol/L hCG. These data suggest that the A572V mutation of the LH/CGR may have effects on the guanine nucleotide binding protein which activates phospholipase C (G(q)) coupling and phospholipase-C activation in addition to its effects on G(s) coupling and activation of adenylyl cyclase. A572V-transfected cells also exhibited a higher affinity, despite an apparent decrease in the number of binding sites, for [I-125]hCG, compared to transfectants with the wild-type LH/CGR. We hypothesize that these differences between the A572V and D578G mutations reflect a greater impact of the A572V mutation on receptor conformation.

AB Acute food withdrawal reversibly inhibits the hypothalamic-pituitary-gonadal axis in men and in rhesus monkeys, and it produces defects in LH pulsatility in normal-weight women. However, the clinical effect of short-term nutritional deprivation on the reproductive axis of normally cycling women has not been evaluated. Thus we studied the effect of a 3-day fast during the midfollicular phase on menstrual cycle length, gonadotropin secretory patterns, follicular development, and ovulation.
After a baseline ovulatory cycle, 12 women within 15% of ideal body weight were randomized to be fed (n = 7) or fasted (n = 10) on cycle days 7 to 9. Five of the women repeated the study and received the alternate diet. Endocrine and metabolic parameters of fasting and reproductive physiology were measured on cycle days 6 to 12. Fasted physiology was demonstrated by characteristic alterations in growth hormone, insulin-like growth factor I, TSH, and T-3 levels. During fed cycles, the number of LH pulses remained constant on cycle days 6, 9 and 11, whereas mean LH levels, LH area under the curve, and LH pulse amplitude increased significantly over this time (all P < 0.05). In contrast, fasted cycles were marked by a significant decrease in the number of LH pulses on the last day of the fast (cycle day 9, P < 0.05) and by a lack of increase over time of mean LH values, LH area under the curve, and LH pulse amplitude. Follicle development, as assessed by daily ultrasound examination and estradiol measurements, was similar in all cycles and was followed by ovulation in all women; follicular and luteal phase lengths of fasted and fed cycles were similar.
We conclude that the alterations in LH secretory dynamics that occur during a S-day fast are not sufficient to perturb follicle development and cycle lengths in normal-weight sedentary women. The resilience of the reproductive axis in these healthy women contrasts with the sensitivity of the hypothalamic-pituitary-gonadal axis to acute nutritional withdrawal in men and in monkeys. We speculate that differences in the set point for sensing fuel availability or in the status of energy balance before the initiation of food deprivation may account for these species-specific and sex-specific variabilities.

In normal children (n = 420; age, 5-20 yr), a marked pubertal increase of serum IGF-I (peak values at age 14-16 yr in both sexes), osteocalcin, and total and skeletal ALP (peak values earlier in girls than in boys) and a small increase in PICP were observed. All osteoblast markers and IGF-I were markedly lower in normal adults (n = 229; age, 21-69 yr) than in children. All osteoblast parameters showed a high degree of correlation (P < 0.001) with each other. In adolescents (n = 104) treated for insulin-dependent diabetes mellitus (IDDM), serum IGF-I (-19%), osteocalcin (-28%), and skeletal ALP (-28%) were markedly decreased, whereas total ALP was significantly increased (29%), and serum PICP remained normal. In adult IDDM (n = 125), both serum IGF-I (-41%) and osteocalcin (-24%) were decreased, but skeletal ALP and PICP remained normal. A similar abnormality in serum IGF-I and osteocalcin was observed in white (n = 61) and Pima Indian (n = 16) non-IDDM patients. The concentration of skeletal ALP was highly significantly correlated (r greater than or equal to 0.9) with total ALP in both normal and diabetic subjects, but the slope of the regression was significantly different, indicating the presence of other, probably intestinal, ALP in all types of diabetes.
In conclusion, the osteoblast function is significantly decreased in diabetic patients, which can best be characterized as a maturation defect, since the early osteoblast marker, PICP, remained normal in all types of diabetes, whereas a later marker, skeletal ALP, is frankly abnormal only in diabetic children. The most mature osteoblast marker, osteocalcin, is decreased in all types of diabetes irrespective of age.

AB Mutations in the insulin receptor gene may lead to insulin resistance and diabetes mellitus in some patients. We have studied an insulin-resistant patient with leprechaunism. Insulin binding to the patient's fibroblasts was markedly decreased. Determination of the nucleotide sequence of the patient's insulin receptor gene revealed heterozygosity for a 2-basepair deletion in exon 15. If the premessenger ribonucleic acid (pre-mRNA) is spliced normally, it causes a replacement of codon 970 in the beta-subunit with a premature chain termination codon, thereby deleting most of the intracellular domain of the receptor. The mRNA transcribed from the allele with a 2-basepair deletion is likely to be unstable because mRNA transcripts from this allele could not be detected by complementary DNA sequencing. Northern blot analysis showed that the patient's insulin receptor mRNA was decreased by 90% compared with that of a control subject, thus suggesting that the patient is a compound heterozygote for two mutations that decrease levels of insulin receptor mRNA. This deletion mutation in exon 15 seems to be a de novo mutation, because it was not detected in either parent. Investigation of the inheritance of a silent sequence polymorphism in exon 17 provided that the deletion occurred in the maternal allele. Furthermore, linkage analysis suggests that the second mutation is derived from the patient's father, although we could not directly identify it by sequencing the coding region of the insulin receptor gene. Therefore, it is possible that this mutation is present in a regulatory domain of the insulin receptor gene, acting in cis-dominant fashion to reduce the levels of insulin receptor mRNA. Analyses of the hypervariable region in the myoglobin and pMCT118 loci were consistent with the assumption that the father and mother studied here are indeed the biological parents of the diseased patient. We hereby conclude that the patient is a compound heterozygote for two mutant alleles, both of which are responsible for the reduced levels of insulin receptor mRNA and insulin binding.

AB GH every 20 min for 24 h, insulin-like growth factor I (IGF-I), IGF-binding protein 3, and estradiol (E(2)) were measured in a 7.3-yr-old girl with precocious puberty due to McCune-Albright syndrome (MAS) who developed stigmata of early acromegaly and in 9 other MAS patients who had no signs of acromegaly. To determine whether the MAS patients had subtle abnormalities in GH secretion, a computerized pulse analysis program was used to compare the MAS data with those from 27 control girls with central precocious puberty who had a similar rate of bone age advance, E(2), and body mass index. We found no differences in mean GH, GH pulse frequency, pulse height, or pulse area between MAS patients and controls except in patient 1, who had an elevated mean +/- SD GH compared with controls (15.4 +/- 2 vs. 4.8 +/- 2.3 mu g/L; P < 0.01) and an elevated IGF-I (908 mu g/L) and IGF-binding protein 3 (5.6 mg/L). None of the GH parameters correlated with body mass index, age, bone age, or E(2) levels in either group. The serum GH in patient 1 fell to near-undetectable levels from 60-180 min after a 100-mu g sc dose of long-acting somatostatin, confirming that this farm of therapy can be effective in cases of GH hypersecretion due to MAS.

AND CAUCASIANS
SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM
LA English
DT Article
ID HYPERTENSION
AB Intracellular magnesium is a cofactor for numerous enzymes involved in carbohydrate metabolism. Magnesium accumulation is dependent upon insulin action and correlates with insulin-mediated glucose uptake. As Pima Indians are known to be insulin resistant, we investigated whether, in response to insulin infusion, they have lower erythrocyte magnesium accumulation than Caucasians. Insulin-mediated glucose uptake was determined by a euglycemic hyperinsulinemic glucose clamp in 29 obese nondiabetic volunteers: 15 Caucasians (8 males and 7 females) and 14 Pima Indians (8 males and 6 females). Pima Indians were younger than Caucasians (mean +/- SD, 28 +/- 7 vs. 39 +/- 8 yr; P < 0.01), but had similar body mass index and fasting/2-h plasma glucose concentrations. Despite higher steady state plasma insulin levels (692 +/- 260 us. 540 +/- 70 pmol/L; P < 0.03), Pima Indians had lower insulin-mediated glucose uptake than Caucasians (108 +/- 20 vs. 244 +/- 32 mg/m(2) . min; P < 0.0001). The mean fasting plasma magnesium concentration was lower in Pima Indians than in Caucasians (0.79 +/- 0.05 vs. 0.85 +/- 0.06 mmol/L; P < 0.01), whereas the mean fasting erythrocyte magnesium concentrations (1.98 +/- 0.10 vs. 2.03 +/- 0.14 mmol/L) were similar in the 2 groups. In response to insulin infusion, erythrocyte magnesium content increased less in Pima Indians than in Caucasians (0.15 +/- 0.07 vs. 0.28 +/- 0.21 mmol/L; P < 0.03). However, this increase was similar in the 2 groups when values were adjusted for insulin-mediated glucose uptake.
In conclusion, nondiabetic Pima Indians have a lower erythrocyte magnesium accumulation in response to insulin infusion; this is probably due to their high degree of insulin resistance. The biochemical and physiological consequences of decreased intracellular magnesium uptake are discussed.

AB Although hundreds of thousands of women in this country have had augmentation mammaplasty, little is known about long-term effects. Clinical studies have documented a decreased ability to detect breast lesions in women with implants, leading to concerns regarding breast cancer risk. There is also anecdotal evidence that implants might have effects on a variety of immune conditions. More recently, concern over carcinogenic effects has heightened given findings that the polyurethane foam, used in a minority of implants to envelope silicone gel, contains chemicals linked to cancer in laboratory animals. Only a few epidemiologic studies on long-term effects have been published, and all have had methodologic limitations, including the possibility of inappropriate comparison rates, limited and/or incomplete follow-up, absence of information on patients characteristics, and lack of specific information on types of implanted material. Several case-control and cohort studies are currently underway which are attempting to overcome methodologic limitations of previous studies. Past descriptive and analytic studies are reviewed. In addition, ongoing follow-up efforts are discussed, with attention given to the methodologic adjuncts necessary for allowing valid assessments of long-term disease effects.

AB Type III cGMP-inhibited phosphodiesterases (PDE3s) play important roles in hormonal regulation of lipolysis, platelet aggregation, myocardial contractility, and smooth muscle relaxation. We have recently characterized two PDE3 subtypes (PDE3A and PDE3B) as products of distinct but related genes. To elucidate their biological roles, in this study we compare cellular patterns of gene expression for these two enzymes during rat embryonic and postnatal development using in situ hybridization. PDE3A mRNA is abundant in adipose tissue and is also expressed in hepatocytes throughout development. This mRNA is also highly abundant in embryonic neuroepithelium including the neural retina, but expression is greatly reduced in the mature nervous system. Finally, PDE3A mRNA is localized in spermatocytes and renal collecting duct epithelium in adult rats.
PDE3B mRNA is highly expressed in the cardiovascular system, including myocardium and arterial and venous smooth muscle, throughout development. It is also abundant in bronchial, genitourinary and gastrointestinal smooth muscle and epithelium, megakaryocytes, and oocytes. PDE3B mRNA demonstrates a complex, developmentally regulated pattern of gene expression in the central nervous system. In summary, the two different PDE3s show distinctive tissue-specific patterns of gene expression suggesting that PDE3A is involved in hormonal regulation of lipolysis and glycogenolysis, while regulation of myocardial and smooth muscle contractility appears to be a function of PDE3B. In addition, the present findings suggest previously unsuspected roles for these enzymes in gametogenesis and neural development.

AB Kaposi's sarcoma (KS) is a proliferative disease of vascular origin particularly frequent in HIV-1-infected homosexual men (AIDS-KS) and characterized by proliferating spindle-shaped cells, angiogenesis, and inflammatory cell infiltration, Previous work has suggested that KS spindle cells are of endothelial cell origin and that chronic immune activation via the release of inflammatory cytokines may cooperate with basic fibroblast growth factor (bFGF) and the HIV-1 Tat protein in the induction and progression of AIDS-KS. Here we show that KS spindle cells have features of activated endothelial cells, and that conditioned media from activated T cells, rich in the same inflammatory cytokines increased in HIV-1-infected individuals, induce normal endothelial cells to acquire the phenotypic and functional features of KS cells, These include (a) acquisition of a similar pattern of cell surface antigen expression; (b) similar proliferative response to bFGF; (c) induction of the responsiveness to the mitogenic effect of extracellular HIV-1 Tat protein that is now able to promote the G1-S transition of endothelial cell cycle; and (d) induction in nude mice of vascular lesions closely resembling early KS as well as the lesions induced by inoculation of KS cells, These results suggest that chronic immune activation, via release of inflammatory cytokines, may play a role in the induction of KS.

AB The bioavailability of nitric oxide (NO) in the human coronary circulation at rest and after acetylcholine (ACH)-induced vasodilation was investigated in 32 patients with angiographically normal coronary arteries, The effects of intracoronary L-N-G monomethyl arginine (L-NMMA) were investigated at rest and after AGH, sodium nitroprusside, and adenosine, L-NMMA (64 mu mol/min) increased resting coronary vascular resistance by 22% (P<0.001), reduced distal epicardial coronary artery diameter by 12.6% (P<0.001), and inhibited AGH-induced coronary epicardial and microvascular vasodilation. These effects were reversed with intracoronary L-arginine. L-NMMA did not inhibit dilation in response to sodium nitroprusside and adenosine,
23 patients were exposed to one or more coronary risk factors, The vasoconstrictor effect of L-NMMA on the epicardial and microvessels was greater in patients free of risk factors: Coronary vascular resistance was 36% higher in patients without risks, compared to 17% higher in patients with risks (P<0.05), Both epicardial and microvascular dilator effects of ACH were greater in patients without risk factors, and the inhibition of these effects by L-NMMA was also greater in patients without risk factors,
Thus: (a) NO contributes importantly to resting epicardial and coronary microvascular tone, (b) coronary vascular dilation in response to ACH is predominantly due to increased production of NO, and (c) despite the absence of angiographic evidence of atherosclerosis, exposure to coronary risk factors is associated with reduced resting and stimulated bioavailability of NO from the human coronary circulation.

AB Despite significant improvements in the primary success rate of the medical and surgical treatments for atherosclerotic disease, including angioplasty, bypass grafting, and endarterectomy, secondary failure due to late restenosis continues to occur in 30-50% of individuals. Restenosis and the later stages in atherosclerotic lesions are due to a complex series of fibroproliferative responses to vascular injury involving potent growth-regulatory molecules (such as platelet-derived growth factor and basic fibroblast growth factor) and resulting in vascular smooth muscle cell (VSMC) proliferation, migration, and neointimal accumulation, We show here, based on experiments with both taxol and deuterium oxide, that microtubules are necessary for VSMCs to undergo the multiple transformations contributing to the development of the neointimal fibroproliferative lesion. Taxol was found to interfere both with platelet-derived growth factor-stimulated VSMC migration and with VSMC migration and with VSMC proliferation, at nanomolar levels in vitro. In vivo, taxol prevented medial VSMC proliferation and the neointimal VSMC accumulation in the rat carotid artery after balloon dilatation and endothelial denudation injury, This effect occurred at plasma levels approximately two orders of magnitude lower than that used clinically to treat human malignancy (peak levels achieved in this model were similar to 50-60 nM), Taxol may therefore be of therapeutic value in preventing human restenosis with minimal toxicity.

AB Purpose: Therapy of hairy cell leukemia has markedly improved. Interferon alfa-2a and pentostatin are active agents. The National Cancer Institute organized an intergroup trial to compare these agents prospectively in untreated patients.
Methods: Patients were randomized to receive either interferon alfa-2a (3 x 10(6) U subcutaneously three times per week) or pentostatin (4 mg/m(2) intravenously every 2 weeks). Patients who did not respond to initial treatment were crossed over.
Results: Of 356 patients on study, 313 were eligible. Among interferon patients, 17 of 159 (11%) achieved a confirmed complete remission and 60 of 159 (38%) had a confirmed complete or partial remission. Among pentostatin patients, 117 of 154 (76%) achieved a confirmed complete remission and 121 of 154 (79%) had a confirmed complete or partial remission. Additional patients achieved criteria for complete remission, but lacked con firmatory follow-up evaluation. Response rates were significantly higher (P < .0001) and relapse-free survival was significantly longer with pentostatin than interferon (P < .0001). The median follow-up duration is 57 months (range, 19 to 82). Myelosuppression was more frequent with pentostatin (P = .013). A multivariate logistic regression analysis of the confirmed complete remissions on pentostatin showed the following factors to be im portant for achieving a complete remission: high hemoglobin level (two-tailed P = .024), young age (P = .0085), and no or little splenomegaly (P = .0029).
Conclusion: Both agents were well tolerated. Pentostatin higher response rates, and the responses were durable. Patient age and clinical status had an impact on outcome with pentostatin. Pentostatin is effective therapy for hairy cell leukemia.

ID WASTE NITROGEN-EXCRETION; DIFFERENTIATION; UREA; ACID
AB Phenylacetate, an inducer of tumor cytostasis and differentiation, shows promise as a relatively nontoxic antineoplastic agent, Phenylacetate, however, has an unpleasant odor that might limit patient acceptability. Phenylbutyrate, an odorless compound that also has activity in tumor models, is known to undergo rapid conversion to phenylacetate by beta-oxidation in vivo. This phase I study examined the pharmacokinetics of phenylbutyrate and characterized the disposition of the two metabolites, phenylacetate and phenylacetylglutamine, Fourteen patients with cancer (aged 51.8 +/- 13.8 years) received a 30-minute infusion of phenylbutyrate at 3 dose levels (600, 1200, and 2000 mg/m(2)), Serial blood samples and 24-hour urine collections were obtained. Samples were assayed by high-performance liquid chromatography. A model to simultaneously describe the pharmacokinetics of all three compounds was developed using ADAPT II. Data were modeled as molar equivalents. The model Ft the data well os shown by mean (+/-SD) coefficients of determination (r(2)) for phenylbutyrate, phenylacetate, and phenylacetylglutamine, which were 0.96 +/- 0.07, 0.88 +/- 0.10, and 0.92 +/- 0.06, respectively. The intrapatient coefficient of variation percentage (CV%) around the parameter estimates were small (range 7.2-33.5%). Phenylbutyrate achieved peak concentrations in the range of in vitro tumor activity (500-2000 mu mol/L) and exhibited saturable elimination (K-m = 34.1 +/- 18.1 mu g/mL and V-max = 18.1 +/- 18 mg/h/kg). Metabolism was rapid; the rimes to maximum concentration for phenylacetate and phenylacetylglutamine were 1 and 2 hours, respectively. The conversion of phenylbutyrate to phenylacetate was extensive (80 +/- 12.6%), but serum concentrations of phenylacetate were low owing to rapid, subsequent conversion to phenylacetylglutamine. The ratio of phenylbutyrate AUC to phenylacetate AUC was 2.66. Thus, phenylbutyrate may not be a prodrug for phenylacetate and should be pursued as an independent antitumor agent.

AB Data on social competence, behavior, and self-esteem were gathered from a large sample of girls with Turner syndrome to determine whether psychological difficulties were associated with Turner syndrome. Subjects included 97 girls with Turner syndrome, 7 to 14 years of age, and 93 girls without Turner syndrome recruited from public schools. The two groups of girls were similar in age, verbal intelligence scores, and racial composition. The girls with Turner syndrome were found, based on both parental and self-report, to be more immature than the girls in the comparison group, with weaker social relationships, school performance, and self-esteem. A decline in self-esteem was also documented for the girls with Turner syndrome, but not the comparison group, as they moved into early adolescence. Although the findings support an increased risk for subtle behavioral problems among girls with Turner syndrome, in most cases the problems endorsed were not severe enough to suggest clinical impairment.

TI CEREBROSPINAL-FLUID LEVELS OF BETA-ENDORPHIN IN PAINFUL AND PAINLESS
DIABETIC POLYNEUROPATHY
SO JOURNAL OF DIABETES AND ITS COMPLICATIONS
LA English
DT Article
AB beta endorphin (beta-EP) is an important modulator of central pain pathways. To examine whether changes in central production of beta-EP contribute to the pathogenesis of diabetic neuropathic pain, we compared the cerebrospinal fluid (CSF) levels of beta-EP and its precursor proopiomelanocortin (POMC) between 15 diabetic patients with chronic painful diabetic polyneuropathy, eight patients with severe painless diabetic neuropathy, and ten nondiabetic controls. Both peptides were measured by specific monoclonal antibody-based two-site immunoradiometric assays (IRMAs). In the diabetic patients with painful neuropathy, mean +/- SD CSF beta-EP concentrations (5.7 +/- 2.2 pmol/L) were comparable to those of the diabetic patients with painless neuropathy (6.0 +/- 2.3 pmol/L) and did nor correlate with the severity of neuropathic pain. CSF beta-EP, but not POMC, concentrations were lower in the diabetic neuropathic patients overall (5.8 +/- 1.9 pmol/L compared to the control subjects (7.6 +/- 2.2 pmol/L) (P < 0.05). CSF POMC showed no intergroup differences. However, POMC levels were 80-fold higher than those of beta-EP and should always be considered when interpreting immunoreactive beta-EP or other derivative peptide levels in CSF. We conclude that CSF beta-EP levels appear to be reduced in diabetic polyneuropathy but they do not relate to the presence of neuropathic pain. This might explain why opioid analgesics are of little, if any, help in alleviating diabetic neuropathic pain.

AB Penicillin G (PcG) conjugated to bovine serum albumin (BSA) was found to retain antibacterial activity against Staphylococcus aureus as judged by growth inhibition and by ultrastructural analyses of the PcG-BSA-treated bacterium. Using the PcG-BSA conjugated to colloidal gold, binding sites of PcG were localized in S. aureus with electron microscopy using a postembedding labeling technique, To our surprise, labeling was observed both on the cell wall and in the cytoplasm of S. aureus. A part of the labeling observed may be attributed to penicillin-binding proteins (PBPs) or their precursors. Also there may be other molecules which bind with PcG in the cell wall and cytoplasm of S. aureus.

AB Human herpesvirus 6 (HHV-6), a T-lymphotropic human herpesvirus, is a potentially immunosuppressive agent that has been suggested to play a role as a cofactor in the natural history of human immunodeficiency virus (HIV) infection. We studied the interactions between HHV-6 and gamma/delta T lymphocytes, a subset of T cells involved in the protective immune response against specific microorganisms. Polyclonal gamma/delta T cell populations, purified from the peripheral blood of healthy adults and activated in vitro with phytohemagglutinin, were exposed to HHV-6, strain GS (subgroup A), at the approximate multiplicity of infection (MOI) of 1. Signs of virus replication were detected as early as 72 h after infection, as documented by immunofluorescence, electron microscopy, and transmission of extracellular virus. Progression of the infection was associated with the appearance of typical cytomorphological changes and, eventually, massive cell death. In contrast, no signs of infection or cytopathic effects were detected after exposure of gamma/delta T lymphocytes to HHV-7, a CD4(+) T-lymphotropic virus closely related to HHV-6. Polyclonal gamma/delta T cells displayed cytolytic activity against both autologous and heterologous target cells infected with HHV-6 and maintained this activity for at least 72 h after infection with HHV-6, despite the high MOI used. As previously documented in mature CD8(+) alpha/beta T cells and natural killer cells, HHV-6 infection induced gamma/delta T lymphocytes to express de novo CD4 messenger RNA and protein, as detected by reverse transcriptase-polymerase chain reaction and fluorocytometry, respectively. Whereas purified CD4(-) gamma/delta T cell populations were per se refractory to HIV infection, they became susceptible to productive infection by HIV-1, strain IIIB, after induction of CD4 expression by HHV-6. These results demonstrate that gamma/delta T cells can be directly targeted and killed by a herpesvirus and may have implications for the potential role of HHV-6 in AIDS.

AB The Janus family of kinases (JAKs) has been shown to be involved in the signal transduction of a number of cytokine receptors. Recently, we have cloned a novel JAK family member, JAK3, that is expressed in natural killer and activated T cells and is coupled functionally and physically to the interleukin 2 (IL-2) receptor in these cells. Here we report that JAK3 was expressed at low but detectable levels in human monocytes. In contrast, JAK3 expression was strongly induced during activation by interferon gamma (IFN-gamma) or lipopolysaccharide. Moreover, JAK3 became tyrosine phosphorylated in response to IL-2, IL-4, and IL-7 but not response to IFN-gamma or granulocyte/macrophage colony-stimulating factor. Together, these findings suggest that JAK3 is functionally important in activated monocytes and cells of the myeloid lineage and is involved in signaling responses of cytokines that use the common gamma-chain of the IL-2 receptor.

AB HTLV-1 is implicated in the development of diverse diseases. However, most HTLV-1-infected individuals remain asymptomatic. How HTLV-1 infection leads to disparate consequences remains a mystery, despite extensive investigation of HTLV-1 isolates from infected individuals. As in human infection, experimental HTLV-1 infection in rabbits is generally benign, although HTLV-1-infected rabbit T cell lines that mediate lethal leukemia-like disease have been reported. We report here that thymuses from mature outbred rabbits inoculated with a lethal HTLV-1 T cell line (RH/K34) showed morphological and biochemical evidence of apoptosis, whereas thymuses from rabbits inoculated with nonlethal HTLV-1 T cell lines showed no signs of apoptosis. Exposure of rabbit or human lymphocytes to purified virus from RH/K34 caused rapid induction of apoptosis, providing an in vitro correlate to the pathogenic effects. By contrast, virus isolated from a nonlethal cell line mediated dose-dependent lymphocyte proliferation. These data implicate lymphocyte apoptosis as a potential mechanism by which the lethal HTLV-1 cell line causes fulminant disease and provide a means to identify factors contributing to HTLV-1 disease. Results from this HTLV-1 infection model can provide insight into variations in HTLV-1 pathogenicity in human infection.

AB A retrospective review of 71 patients with probable Alzheimer's disease was analyzed with respect to nursing evaluations of sundowning status (recurring confusion or agitation in the late afternoon or early evening). The prevalence of sundowning (including probable sundowners) was 24%. Sundowners and non-sundowners differed with regard to number of sedatives received daily, particularly chloral hydrate, and the number of days on the inpatient unit. There were no differences between sundowners and non-sundowners with respect to other types of medications, medical diagnoses, current age, age of onset of Alzheimer's disease, or Mini-Mental State Exam. Restlessness was the most common sundowning behavior, although multiple behavioral disturbances were seen. This survey suggests that the sundown syndrome is a common problem in severely demented Alzheimer's patients and requires further study.

To define more precisely a role for the tyrosine phosphatase CD45 in Fc epsilon RI-mediated signaling, we have transfected the three subunits of Fc epsilon RI into wild-type jurkat and a CD45-deficient jurkat derivative. Here we demonstrate that CD45 is necessary for the initiation of calcium flux through the transfected Fc epsilon RI. In contrast to the effect of phosphatase inhibitors, the tyrosine phosphorylation levels of beta and gamma after aggregation of Fc epsilon RI are surprisingly reduced, relative to wild-type jurkat, in the CD45-deficient cells. After reconstitution of the CD45-deficient cells with a chimeric molecule containing the cytoplasmic phosphatase domains of CD45, both the base line and activation-induced tyrosine phosphorylation levels are increased. By examining Lck autophosphorylation, we find that Fc epsilon RI aggregation induces an increase in Lck enzymatic activity only in wild-type Jurkat and the CD45-deficient Jurkat reconstituted with chimeric CD45. This regulation of src-family tyrosine kinase activity may be the means by which CD45 controls aggregation-induced receptor phosphorylation.

AB A novel form of phosphocholine (PC), p-nitrophenyl-6-(O-phosphocholine)hydroxy (EPC) coupled to keyhole limpet hemocyanin (KLH) has been compared with unencapsulated, avirulent Streptococcus pneumoniae (R36a) and with the traditional thymus-dependent form of PC, diazophenylphosphocholine (DPPC)-conjugated KLH for its vaccine potential against virulent S. pneumoniae. Immunization with any of these three PC-containing Ags protects normal mice against a lethal challenge with 10(4) S. pneumoniae, whereas only EPC-KLH provides total protection to Xid mice. DPPC-KLH and unencapsulated S. pneumoniae confer less than 40% protection in Xid mice. Passive transfer of a PC-specific hybridoma Ab made from EPC-KLH-immunized Xid mice also provided protection against lethal challenge with S. pneumoniae, Protective anti-PC Ab were capable of binding to the surface of virulent bacteria, whereas anti-PC Ab incapable of binding to the bacterial surface failed to protect. Furthermore, serum Ab from EPC-KLH immunized and protected mice bound to S. pneumoniae, whereas secondary Abs from DPPC-KLH- or R36a-immunized mice failed to bind to the bacteria. EPC-KLH is potentially a vaccine candidate for pneumococcal prophylaxis in settings of immune compromise.

AB The administration of murine TNF-alpha to colon (C)-26 bearing mice, significantly protects the host against the catabolic effects of the tumor. This effect of exogenous TNF-alpha can be primarily attributed to tumor lysis rather than to a direct anticachectic action. Murine peritoneal macrophages cultured with the C-26 line or with C-26 culture supernatant do not release TNF-alpha in response to LPS stimulation. The reduction in TNF-alpha levels is associated with a significant increase in IL-10 levels. Single cell suspension of freshly disaggregated C-26 tumor (which contains host macrophages), do not produce TNF-alpha but contain significant levels of PGE(2) and IL-10. In contrast, PGE(2) but not TNF-alpha or IL-70 can be detected in the C-26.IVX cell line that is used to generate tumors in vivo. Neutralizing anti IL-10 Ab but not isotype-matched Ab, significantly reverses the inhibitory effect of the tumor cells and their culture supernatant on macrophage TNF-alpha release. Additional evidence is presented to indicate that the C-26-derived inhibitory activity is related to PGE(2). Taken together, these results support the hypothesis that tumor-derived PGE(2) prevents tumor-infiltrating macrophages from producing TNF-alpha, in part by augmenting macrophage IL-10 synthesis.

AB APC dysfunction may be important in immune dysregulation associated with HIV disease. Langerhans cells, epidermal APC, can be infected with HIV, although their function in HIV-infected persons has not been studied. Therefore, we studied the immunologic function of Langerhans cells, in parallel with blood APC (enriched for monocytes/macrophages (M phi)) function, in 21 HIV-seropositive (HIV+) and 21 HIV-seronegative volunteers, including three monozygotic twin pairs discordant for HIV serology. Langerhans cells from HIV+ patients were quantitatively normal and expressed normal levels of HLA-DR. However, Langerhans cells from AIDS patients and M phi from both AIDS and HIV+ non-AIDS patients stimulated allogeneic T cells less well compared with control APC. In addition, decreased recall Ag- and mitogen-induced T cell responsiveness was observed in HIV+ patients using either autologous Langerhans cells or autologous M phi as APC/accessory cells. Interestingly, Langerhans cells and M phi isolated from HIV+ twins (CD4(+) cell counts of 181, 271, and 562/mm(3)) were able to present recall Ag normally to HIV-uninfected syngeneic T cells. In summary, APC from HIV+ patients were impaired in their ability to generate a primary immune response (i.e., alloantigen-induced T cell stimulation), but they retained the ability to generate a secondary immune response (i.e., recall Ag-induced syngeneic T cell stimulation). Thus, these findings suggest that defects in secondary immune responses commonly observed in HIV disease are dependent on T cell dysfunction alone, whereas defective primary immune responses may be secondary to both T cell and APC dysfunction.

AB Homosexual males often present signs of immune activation and are likely to have increased levels of inflammatory cytokines such as IL-1 beta, TNF-alpha, and IFN-gamma. These individuals develop Kaposi's sarcoma (AIDS-KS) more frequently than other HIV-1-infected groups. Our previous work demonstrated that inflammatory cytokines stimulate the growth of spindle cells derived from AIDS-KS lesions (AIDS-KS cells) and that these cells produce high levels of bFGF that mediate autocrine and paracrine (endothelial) cell growth and angiogenesis. Here we show that AIDS-KS cells constitutively produce and release bioactive bFGF in the absence of cell death, and that extracellular bFGF exist in both a soluble and a bound form; the latter can be released by treatment with trypsin, heparin, or heparinase I. Inflammatory cytokines stimulate both the synthesis and release of biologically active bFGF from KS cells and enhance their ability to induce angiogenic KS-like lesions in nude mice. Because bFGF is highly expressed in primary KS lesions, and is a mediator of KS-like lesion formation, these results suggest that the export of bFGF induced by inflammatory cytokines may play a critical role in the induction and progression of KS in HIV-1-infected homosexual men.

AB The prevalence of antibodies to hepatitis C virus (anti-HCV), the behavioral and laboratory-derived risk factors for anti-HCV, and the quantity and homology of HCV RNA were assessed among 1039 non-injection drug-using sexually transmitted disease (STD) patients representing 309 sex partnerships. Thirty-seven (7%) of 555 males and 19 (4%) of 484 females had anti-HCV. In logistic regression analyses, factors associated with anti-HCV included age (P < .001), greater numbers of lifetime sex partners (P = .023), human immunodeficiency virus infection (P < .001), Trichomonas infection (P < .001), cigarette smoking (P < .001), and male homosexual exposure (P = .012). Among couples, females whose sex partners were anti-HCV positive were 3.7 times more likely to have anti-HCV than females whose sex partners were anti-HCV negative (P = .039). The proportion of RNA homology between anti-HCV positive females and their male partners (94%) was higher than among randomly selected patients (82%). Sexual transmission of HCV may contribute to the high prevalence of anti-HCV reported in urban settings.

AB This analysis investigated variability of survival time in a cohort of 553 human immunodeficiency virus type 1 (HIV-1)-infected homosexual or bisexual men with <50 CD4(+) cells/mu L. Median survival after the first CD4(+) cell count <50/mu L was 1.34 years; 25% survived greater than or equal to 2 years. Multivariate analysis showed longer survival with concurrent acyclovir and zidovudine use, hemoglobin greater than or equal to 12 g/dL, and full-time employment (P < .0001). Other significant covariates associated with longer survival included African-American race, no prior AIDS illness, weight loss <4.5 kg, and zidovudine use (with or without concurrent acyclovir) after CD4(+) cells fell to <50/mu L. An easily derived score identified Multicenter AIDS Cohort Study subjects likely to survive >2 years after CD4(+) cell count was <50/mu L. Survival once CD4(+) cell count fell below 50/mu L may be longer for persons with a good performance status and specific clinical markers. Health care providers should consider these variables in decision-making strategies and design of clinical trials.

AB Guaymi Indians, a non-intravenous drug-using population in which human T cell lymphotropic virus type II (HTLV-II) is endemic, were studied in Changuinola, Panama, to identify the prevalence and modes of transmission of HTLV-II, A population-based survey showed that 352 (9.5%) of the 3686 participants were seropositive for HTLV-II, Infection rates were the same for male and female subjects and increased significantly with age, beginning in young adulthood. HTLV-II infection status was highly concordant among spouses (P < .001) and between mother and child; of children aged 1-10 years, 36 of 219 born to seropositive mothers were seropositive compared with 3 of 997 born to seronegative mothers (P < .001), The strong associations of HTLV-II infection with age and with an infected spouse in adults and of infection in children with infection in their mothers strongly suggest sexual and mother-to-child transmission of HTLV-II in this population.

AB Herpes B virus (BV) is a common cause of recurring mucocutaneous infections in monkeys of the genus Macaca, Like its human counterpart, herpes simplex virus (HSV), BV establishes lifelong latency and can be reactivated from infected monkeys symptomatically or asymptomatically, Incidental infection of humans handling BV-shedding monkeys can result in fatal meningoencephalitis, To determine whether humans exposed to infected monkeys can acquire asymptomatic BV infections, 480 subjects were evaluated in a controlled seroprevalence study, Sera from 321 primate handlers, including many with repeated injuries inflicted by Macaca monkeys, and 159 people never exposed to monkeys were tested in blinded fashion by both competition ELISA and Western blot to determine the prevalence of BV and HSV seropositivity, Although 293 persons proved positive for HSV antibodies, no primate handlers or control subjects showed BV-specific antibody responses, There is no serologic evidence that BV causes asymptomatic infections in humans.

AB The T cell antigen receptor complex (CD3/Ti) plays a sole in specific antigen recognition as well as in signal transduction, with its surface expression required for the function of several other structurally distinct receptor systems, including CD2, Ly-6(TAP), and Thy-1. In this communication, evidence is presented suggesting an association between the surface expression of CD3/Ti and that of the type 1 interferon (IFN) receptor in a CD4(+) murine T cell clone, We tested the proliferative responses and their capacity to be inhibited by type 1 IFN with the wild-type, CD3/Ti-positive T cell clone and its CD3/Ti-negative variants, The CD3/Ti-negative variants did not respond to specific antigen or anti-CD3 antibody stimulation but they did respond to T cell growth factor (TCGF), stimulation as did the wild-type parental cells, Therefore, the type 1 IFN inhibition of TCGF-stimulated proliferative responses of wild-type and variant cells were compared, Both natural and recombinant type 1 IFNs inhibited TCGF-induced tritiated thymidine (H-3-TdR) incorporation in the wild-type T cell clone, with a ID50 of 60-80 U/ml. By contrast, the variants required much higher doses of type 1 IFN. The ID50 with natural murine IFN-beta was 10,000 U/ml, but this same dose of human IFN-alpha A/D gave only a marginal inhibitory effect, Accompanying the loss of IFN responsiveness, these variants also exhibited a loss of high-affinity type 1 IFN receptors, Taken together, these data suggest that the CD3/Ti complex plays a role in the surface expression of the type 1 IFN receptor in a CD4(+) T cell clone, Given the role of the CD3/Ti in several other receptor systems, the present observations further implicate the central position of the CD3/Ti complex in orchestrating ligand-receptor events on the T cell surface.

AB Polymorphonuclear neutrophils (PMNs) are the major host defense against pseudohyphae, the invasive form of Candida species. We studied the effects of granulocyte colony-stimulating factor (G-CSF) and interferon-gamma (IFN-gamma) on the PMN-induced damage of pseudohyphae of Candida albicans, Candida tropicalis, and Candida parapsilosis in vitro by using two antifungal assays: a modified limiting dilution assay and a colorimetric metabolic 3-(4,5-dimethylthiazlol-2-yl)-2,5-diphenyl- tetrazolium bromide assay. PMNs from healthy volunteers were incubated with either G-CSF (100-10,000 U/ml) or IFN-gamma (10-5000 U/ml) or buffer at 37 degrees C for 90 min and their capacity to damage nonopsonized pseudohyphae was then measured. C. tropicalis appeared to be the most susceptible species, whereas C. parapsilosis showed the highest rate of resistance to PMN damage. G-CSF (500-10,000 U/ml) and IFN-gamma (100-1000 U/ml) enhanced the antifungal activity of PMNs against C. albicans pseudohyphae (P < .01 and P < .05). Among the others, G-CSF enhanced PMN-induced damage of C. parapsilosis at concentrations 500-10,000 U/ml(P < .05), whereas it enhanced damage of C. tropicalis only at 10,000 U/ml (P < .01). IFN-gamma (100-1000 U/ml)-primed PMNs also caused augmented damage of C. parapsilosis (P < .05) but not of C. tropicalis at the same concentrations. Species-dependent differences exist in the responses of PMNs to Candida pseudohyphae and G-CSF as well as IFN-gamma are important immunomodulators of phagocytic host defenses against them.

SENSITIVITY

DT Article
ID SEQUENCE
AB In order to improve the efficiency of BURST imaging, a new phase-modulation scheme of the DANTE-type RF excitation is proposed. It is shown that analytical optimization of the phase-modulation scheme with optimal SNR can be found for an arbitrary number N of subpulses in the RF excitation. Both theory and experiment indicate a maximum attainable gain in efficiency of the square root of N, compared to nonmodulated (constant-phase) excitation schemes. (C) 1995 Academic Press, Inc.

Compound 1 showed remarkable cytotoxicity in vitro against panels of central nervous system cancer (SF-268, SF-539, SNB-75, U-251), non-small cell lung cancer (HOP-62, NCI-H266, NCI-H460, NCI-H522), small cell lung cancer (DMS-114), ovarian cancer (OVCAR-3, SK-OV-3), colon cancer (HCT-116), renal cancer (UO-31), a melanoma cell line (SK-MEL-5), and two leukemia cell lines (HL-60 [TB], SR), with GI(50) values in the low micromolar to nanomolar concentration. range. This substance also inhibited tubulin polymerization (IC50=0.83 +/- 0.2 mu M) and the binding of radiolabeled colchicine to tubulin with 59% inhibition when present in equimolar concentrations with colchicine. Compound 2 also showed cytoxicity against medulloblastoma (TE-671) tumor cells with an ED(50) value of 0.98 mu g/ml. Compound 1 appears to be the first example of a flavonol to exhibit potent inhibition of tubulin polymerization and, therefore, warrants further investigation as an antimitotic agent.

AB The 7315c pituitary tumor cell expresses a homogeneous population of dopamine receptors that are functionally similar to brain dopamine D-2 receptors. [H-3]-Sulpiride binding to 7315c cell homogenates was specific and saturable, and K-I Values for compounds to compete for these sites were highly correlated with values for the same compounds at D-2 receptors in brain. Dopamine maximally inhibited similar to 65% of forskolin-stimulated cyclase activity in cell membranes. Some D-2 agonists had lower efficacies, suggesting that some compounds are partial agonists at this receptor. Removal of GTP from the assay buffer or pretreatment of the tissue with pertussis toxin abolished the Inhibition of adenylyl cyclase by dopamine. Immunodetection of most of the known G alpha subunits revealed that G(i1), G(i2), G(i3), G(o) G(q) and G(s) are present in the 7315c membrane. Pretreatment with the AS antibody (which recognizes the C-terminal regions of G alpha(i1) and G alpha(I2)) significantly attenuated the inhibition of adenylyl cyclase activity by dopamine, whereas antibodies to C-terminal regions of the other G alpha subunits had no effect. These findings suggest that the dopamine D-2 receptor regulates cyclase inhibition predominantly via G(i1) and/or G(i2) and that the 7315c tumor cells provide a useful model for studying naturally expressed dopamine D-2 receptors in the absence of other dopamine receptor subtypes.

AB Mice infected with the LP-BM5 murine leukemia virus mixture develop severe immunosuppression and an encephalopathy characterized by spatial learning deficits. Twelve weeks after infection of C57BL/6J mice with LP-BM5, significant (50-60%) reductions in Met-enkephalin and substance P levels were observed in the striatum, whereas somatostatin levels were unchanged. In addition, a 39% decrease in hypothalamic substance P concentrations was observed, with no alteration in Metenkephalin levels. The apparent selectivity of the decrease in neuropeptide concentrations indicates that a functional alteration of the primary striatal efferent neurons occurs in this infection, which may contribute to the impairment of spatial learning observed in these mice. Moreover, this decrease in striatal neuropeptide levels is similar to the neuropathological changes in basal ganglia observed in HIV-infected individuals and is consistent with previous studies suggesting that the LP-BM5-infected mouse mat serve as a useful model of AIDS dementia.

TI MODIFIED SACCADES EVOKED BY STIMULATION OF THE MACAQUE SUPERIOR
COLLICULUS ACCOUNT FOR PROPERTIES OF THE RESETTABLE INTEGRATOR
SO JOURNAL OF NEUROPHYSIOLOGY
LA English
DT Note

AB 1. Models of the saccadic system propose that there is an integration of the pulse signal, and there is good evidence that the integrator is reset gradually (Nichols and Sparks 1994, 1995). Other studies of the superior collicular contribution to the saccadic system have proposed a sensory, not motor, nature for its signal.
2. To test experimentally the resetting of the integrator and the nature of the collicular signal, we electrically stimulated the superior colliculus during periods of fixation and during the course of visually guided saccades. Trains of stimuli which were presented during periods of fixation evoked saccades with fixed vectors. Identical stimulation at the beginning of a visually guided saccade evoked saccades whose direction was rotated and amplitude extended from the fixed vector. The direction of the rotation was opposite that of the visually guided saccade, and the magnitude of this rotation could be as large as 80 degrees.
3. Stimulation which was applied at progressively later times during the visually guided saccade, evoked saccades with progressively smaller rotations and progressively less elongations. The time period during which saccades were modified persisted beyond the end of the visually guided saccade, when the eyes were stationary. Thus, we confirm the previous findings (Nichols and Sparks 1994, 1995; Robinson, 1972), that the end of the saccade is not a period of quiescence within the oculomotor pathways.
4. Our results confirm that the resetting of the integration of the saccade signal is gradual rather than abrupt. Furthermore, these data suggest that the superior colliculus signals a motor error.

AB GABA (gamma-amino butyric acid), a fast-acting synaptic transmitter in the mature CNS, is synthesized from glutamate by GAD (glutamic acid decarboxylase). We have developed an ultrasensitive PCR technique to quantify the expression of GAD-related mRNAs during the development of the rat cervical spinal cord and have localized them using in situ hybridization. GAD65, GAD67, and an alternatively spliced variant of GAD67, EP10, were quantified each day from embryonic (E) day 11 through E21, and at postnatal days 0, 7, 14, and adult, GAD65 and GAD67 mRNAs were detected at E11 and increased exponentially over three orders of magnitude during embryonic development, then declined approximately threefold in the first 2 postnatal weeks, While the exponential growth phase coincided with the progressive appearance of GAD67 in situ signals in both the ventral and dorsal cord, the postnatal decline coincided with the virtual disappearance of expression in the ventral region, EP10 expression was prominent in the embryo, then declined markedly together with the mRNA encoding the neuroepithelial stem cell marker, nestin. The concerted appearance of GAD-related mRNAs paralleled transcripts encoding neuronal markers (light and heavy neurofilaments) and also closely correlated with the expression of GABA, mRNAs encoding GABA(A) receptor subunits, and depolarizing responses to GABA, We have used the results on GAD-related mRNA expressions to formulate a simple, minimal mathematical model that accounts for their kinetics in terms of positive and negative feedback loops.

AB TrkA is a receptor tyrosine kinase whose activation transduces NGF signaling. TrkA expression has been demonstrated in NGF-responsive adult basal forebrain cholinergic neurons (BFCNs).
Several lines of evidence have suggested that endogenous NGF plays a role in the development and differentiation of these neurons. We examined TrkA expression during development. TrkA mRNA and protein were present in basal forebrain neurons during the entire postnatal period; the distribution of neurons bearing these markers was identical to that for those containing choline acetyltransferase (ChAT) mRNA, suggesting that, as in the adult, TrkA gene expression is localized to BFCNs. The expression of TrkA and ChAT followed a very similar temporal pattern, suggesting regulation by the same factor(s). We discovered that NGF administration in vivo activated TrkA receptors, and increased both TrkA and ChAT mRNA; conversely, anti-NGF infusions suppressed expression of both genes. These results suggest that endogenous NGF regulates expression of TrkA and ChAT. Finally, while NGF infusion increased the size of developing BFCNs, NGF antibodies inhibited the normal developmental increase. The results are evidence that endogenous NGF acts on developing BFCNs to enhance gene expression and cellular differentiation.

AB To study injury-induced astrocytic responses associated with regrowth of axons and regeneration of myelin, the method of Collins and colleagues was used to make focal cryogenic lesions in spinal cords of adult rats (Collins et al.: J Neuropathol Exp Neurol 45: 742-757, 1986). The duration of cryogenic injury (CI), the size of the cryode, and its temperature were chosen to destroy all myelin sheaths and axons without producing cavities or hemorrhages, Messenger RNA and peptide distributions of insulin-like growth factor I (IGF-I), IGF-I receptor (IGFR-I), IGF binding protein 2 (IGFBP-2), glial fibrillary acidic protein (GFAP), and myelin basic protein (MBP) were studied 3-56 days after CI by in situ hybridization and immunocytochemistry, At 3 days, vimentin-positive, GFAP-negative astrocyte-like cells in the lesion expressed IGF-I mRNA and peptide and 7 days after CI, both were expressed by typical GFAP-positive, hypertrophic astrocytes, many of which also were vimentin-positive. Levels of IGF-I, IGFBP-2, and GFAP mRNA and peptide were higher in lesion astrocytes after 14 days, They attained maximum levels at 21-28 days before declining to near control levels at 56 days, Decreasing relative levels of oligodendroglial MBP mRNA were found in and around lesions 7-14 days after CI; subsequently, rising levels accompanied remyelination, At 28 and 56 days after CI, some transferrin-positive, oligodendroglia-like cells also were immunostained by anti-IGFR-I. Our findings suggest that early astrocytic production of IGF-I and IGFBP-2 may be involved in the myelin regeneration which occurs in this model of spinal cord injury. (c) 1995 Wiley-Liss, Inc.(*)

AB CC49 is a murine monoclonal antibody (MAb) that reacts against the TAG-72 antigen. We carried out a Phase I study with escalating doses of I-131-CC49 in patients with advanced colorectal cancer expressing the TAG-72 antigen to determine the dose-limiting toxicity and therapeutic efficacy, if any, of the radioimmunoconjugate. Methods: Twenty-four patients with TAG-72- expressing colorectal cancer were treated with escalating doses of I-131-CC49 Starting at 15 mCi/m(2) and going up to 90 mCi/m(2) of I-131 labeled to 20 mg MAb CC49. Patients were selected if TAG-72 was expressed in greater than or equal to 50% of cells in previously resected tumor and at least one metastasis was demonstrable on standard imaging such as CT. All patients had failed conventional chemotherapy and had not received prior radiotherapy or murine MAb. Patients were under radiation isolation precautions until whole-body radioactivity decreased to less than or equal to 5 mR/hr at 1 m. Whole-body scintigrams were obtained prior to discharge and 1 and 2 wk after infusion in all patients. SPECT imaging was carried out at least once in all patients. Results: All patients had excellent targeting of radioactivity to known tumor sites. There was no nonhematologic toxicity. Hematologic toxicity was more pronounced in those patients who had received extensive prior chemotherapy. There were no major responses. All patients developed an immune response (HAMA) within 4 wk of therapy. Conclusion: Radioimmunotherapy with I-131-CC49 is safe and there is significant therapeutic efficacy in this Phase I trial at the doses studied. There is excellent targeting of radioactivity to antigen-positive tumors. Dose-limiting toxicity is hematopoietic, with the maximum tolerated dose in this group of heavily pretreated patients being 75 mCi/m(2).

TI OUTCOME OF PARTIAL SPLENECTOMY FOR TYPE-I GAUCHER DISEASE
SO JOURNAL OF PEDIATRICS
LA English
DT Note
AB Partial splenectomy was introduced to achieve the benefits of splenectomy and to avoid the risk of overwhelming infection in patients with symptomatic Gaucher disease. We observed regrowth of the splenic remnant, reemergence of preoperative symptoms, and new bone involvement among most of our patients who had undergone partial splenectomy. Enzyme replacement therapy has markedly limited indications for splenectomy, partial or total, for Gaucher disease.

AB Background: We evaluated data from prospectively identified twins to understand better the mechanisms and covariates of mother-to-infant transmission of human immunodeficiency virus (HIV).
Methods: Using data obtained from an international collaboration and multivariate quasilikelihood modeling, we assessed concordance, birth order, route of delivery, and other factors for HIV infection in 115 prospectively studied twin pairs born to HIV-infected women. Actuarial methods were used to evaluate overall survival and survival free of acquired immunodeficiency syndrome for HIV-infected twins.
Results: Infection with HIV occurred in 35% of vaginally delivered firstborn (A) twins, 16% of cesarean-delivered A twins, 15% of vaginally delivered second-born (B) twins, and 8% of cesarean-delivered B twins. In a multivariate model, the adjusted odds ratios for HIV infection were 11.8 (confidence interval: 3.1 to 45.3) for concordance of infection with the co-twin, 2.8 (confidence interval: 1.6 to 5.0) for A versus B twins, and 2.7 (confidence interval: 1.1 to 6.6) for vaginally delivered versus cesarean-delivered twins. Among A twins, 52% (lower confidence limit: 6%) of the transmission risk was related to vaginal delivery, Comparing vaginally delivered A twins (infants most exposed to vaginal mucus and blood) to cesarean-delivered B twins (infants least exposed), 76% (lower confidence limit: 48%) of the transmission risk was related to vaginal exposure. Infected B twins had slightly reduced Quetelet indexes and more rapid development of illnesses related to acquired immunodeficiency syndrome.
Conclusions: These results indicate that HIV infection of B twins occurs predominantly in utero, whereas infection of A twins (and, by implication, singletons) occurs predominantly intrapartum, We propose that intrapartum transmission is responsible for the majority of pediatric HIV infections and that reducing exposure to HIV in the birth canal may reduce transmission of the virus from mother to infant.

PHARMACOLOGY
AB The ability of indirect dopamine agonists to induce gnawing in male C57Bl/6J mice was compared to that of direct dopamine agonists acting at dopamine D-1 or D-2 receptor subtypes. Holes left by the mice on the corrugations of packing cardboard were used as an objective index of gnawing. Indirect dopamine agonists, including dopamine releasers such as fencamfamine, (+)-amphetamine and amfenolic acid and dopamine uptake inhibitors such as cocaine, GBR 12909 {1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-[3-phenylpropyl]piperazine diHCl} and nomifensine produced dose-dependent increases in gnawing. None of the direct agonists (e.g., apomorphine, quinpirole or SKF 82958 [(+/-)-6-chloro-7,8-dihydroxy-3-allyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine]) increased gnawing. Although these compounds varied in potency and efficacy, 18 structurally diverse compounds induced gnawing in 100% of the mice tested. Four weak indirect agonists (3,4-methylenedioxymethamphetamine, amantadine, 2-phenylethylamine and benztropine) failed to induce gnawing. The lack of efficacy of postsynaptic dopamine agonists was not changed by various combinations of postsynaptic agonists (e.g., dopamine D-1 and D-2 agonists in combination). Nonetheless, the dopaminergic nature of the gnawing response was confirmed in experiments in which a host of compounds with primary actions at nondopaminergic sites did not induce gnawing; compounds included nicotine, caffeine, dizocilpine, lidocaine, fluoxetine and nisoxetine. In addition, both the dopamine D-1 antagonist SCH 23390 [R-(+)-7-chloro-8-hydroxy-3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine], the D-2 antagonist eticlopride and the dopamine D-1/D-2 antagonist flupenthixol produced dose-dependent blockade of gnawing induced by either cocaine or methylphenidate, All of the antagonists blocked gnawing at doses below those producing decreases in spontaneous locomotor activity, with eticlopride showing the greatest selectivity in blocking gnawing over locomotor suppression (7- to 14-fold). Given the general contrast between the effects of direct and indirect dopamine agonists, the present procedure could serve as a rapid in vivo method of distinguishing direct- from indirect-acting dopamine agonists.

AB Several dopamine agonists, administered i.m., produced persistent, excessive and non-localized scratching in squirrel monkeys (Saimiri sciureus). Studies were conducted with a series of drugs to determine the pharmacological mechanisms responsible for this effect. All of the dopamine D-2 agonists studied produced dose-related increases in scratching, whereas several dopamine D-1 receptor agonists, indirect dopamine agonists and drugs acting on other receptors failed to produce dose-related increases in scratching. The scratching produced by D-2 agonists was stereospecific; (-)-NPA produced scratching whereas its (+)-enantiomer was inactive up to doses 300-fold higher. Scratching induced by quinpirole was attenuated by both D-2 and D-1 antagonists, and this antagonism was stereospecific, with the D-2 antagonist (-)-eticlopride, but not its enantiomer, active. Sensitivity developed to the effects of D-2 agonists with the quinpirole dose-effect curve shifting to the left by a factor of approximately 64. Two partial D-2 receptor agonists (SDZ 208-911 and SDZ 208-912) had limited efficacy in producing scratching, however, one partial D-2 receptor agonist (terguride) was fully efficacious, suggesting that there are spare receptors for this effect. The peripherally active dopamine antagonist domperidone and the histamine antagonist diphenhydramine also reduced the scratching induced by D-2 agonists, but not to the same extent as centrally acting D-2 antagonists. Scratching in squirrel monkeys is an effect that appears to be due to agonist actions at D-2 receptors, and may be mediated by a release of histamine. This behavioral activity may be useful as an in vivo indication of D-2 receptor activity in primates.

AB To distinguish vasoactive intestinal peptide (VIP) receptors in the brain-mediating neurotransmission and neurotrophism, potent VIP analogues were designed. Using a single amino acid substitution and the addition of a fatty acyl moiety, an analogue was devised that exhibited both a 100-fold greater potency than VIP and specificity for a VIP receptor associated with neuronal survival. This VIP agonist increased neuronal survival via a cAMP-independent mechanism. Identical chemical modification of a prototype VIP antagonist (Met-Hybrid, Neurotensin(6-11)-VIP7-28) also resulted in a 100-fold greater potency in blocking VIP-mediated increases in neuronal survival. Blockade of circadian activity rhythms was limited to VIP antagonists that could inhibit VIP-mediated increases in cAMP. These lipophilic peptides provide novel tools in receptor discrimination and drug design.

AB Although plasma levels of Met-enkephalin and beta-endorphin are elevated in patients suffering from liver failure, it is not known whether central nervous system (CNS) opioidergic neurotransmission is altered in these patients. Such changes may contribute to the motor dysfunction, psychiatric abnormalities and CNS depression observed in hepatic encephalopathy (HE). Therefore, Met- and Leu-enkephalin, dynorphin A and beta-endorphin levels were measured in discrete brain regions and plasma from thioacetamide-treated rats in Stages II to IV of HE. Pituitary and plasma beta-endorphin, Met- and Leu-enkephalin concentrations increased with the severity of HE by 50 to 290%. Pituitary and brainstem dynorphin A levels increased whereas plasma levels decreased in rats with thioacetamide-induced fulminant hepatic failure. Both striatal Met- and Leu-enkephalin levels increased and hypothalamic concentrations decreased in HE. Concurrent with the increase in striatal Met-enkephalin levels was a 26 to 48% decrease in the density of striatal and hypothalamic delta receptors. No change in either the density or affinity of radioligand binding to mu or delta receptors was observed in the CNS. Finally, administering (+/-)-naloxone (5 and 10 mg/kg) or (+/-)-naltrexone (5-15 mg/kg), but not (+)-naloxone (10 mg/kg), significantly increased the motor activity of rats with Stage III HE. Whereas elevated plasma levels of opioid peptides may play a role in the peripheral manifestations of hepatic failure (ascites and hypotension), increased CNS levels of these peptides may be involved in the neuropsychiatric abnormalities characteristic of HE. Thus, opioid antagonists may be effective in ameliorating some of the neurological manifestations of HE.

AB Earlier work characterized the binding of the high-affinity cocaine analog 3 beta-(4-(125)iodophenyl)-tropane-2-carboxylic acid methyl ester ([I-125]RTI-55) to membranes prepared from rat caudate. That investigation demonstrated that [I-125]RTI-55-labeled serotonin (5-HT) transporters in addition to dopamine (DA) transporters and resolved [I-125]RTI-55 binding to 5-HT transporters into two distinct components. In the present study, we characterized [I-125]RTI-55 binding to membranes prepared from whole rat brain minus caudate. The first series of experiments established that [I-125]RTI-55 labels both DA and 5-HT transporters and that 50 nM paroxetine and either 1000 nM 1-[2-(diphenyl methoxy)ethyl]-4-(3-phenylpropyl)homopiperazine (LR1111) or 500 nM (RTI-120) could be used to block [I-125]RTI-55 binding to the 5-HT and DA transporters, thereby generating selective assay conditions for the DA and 5-HT transporters, respectively. Selective lesioning of dopaminergic and serotonergic neurons with intracerebroventricular 6-hydroxydopamine and 5,7-dihydroxytryptamine selectively decreased [I-125]RTI-55 binding to DA and 5-HT transporters, respectively, thereby confirming the selectivity of the assay conditions. The ligand-selectivity pattern of the whole brain minus caudate 5-HT transporter correlated significantly with that of the caudate 5-HT transporter, although there were some striking differences for selected test agents. Additional experiments resolved [I-125]RTI-55 binding to the 5-HT transporter into two components. A ligand-selectivity analysis of the two components failed to identify a highly selective test agent. In summary, the major findings of the present study are that [I-125]RTI-55 labels both DA and 5-HT transporters in membranes prepared from whole brain minus caudate, that 50 nM paroxetine and either 1000 nM LR1111 or 500 nM RTI-120 can be used as a blocking agent to generate selective assay conditions for the DA and 5-HT transporters, respectively, and that [I-125]RTI-55 binding to the 5-HT transporter can be resolved into two similar components.

AB The present study has investigated the pharmacology of SNC 80, a nonpeptidic ligand proposed to be a selective delta agonist in vitro and in vivo. SNC 80 was potent in producing inhibition of electrically induced contractions of mouse vas deferens, but not in inhibiting contractions of the guinea pig isolated ileum (IC50 values of 2.73 nM and 5457 nM, respectively). The delta selective antagonist ICI 174,864 (1 mu M) and the mu selective antagonist CTAP (1 mu M) produced 236- and 1.9-fold increases, respectively, in the SNC 80 IC50 value in the mouse vas deferens. SNC 80 preferentially competed against sites labeled by [H-3]naltrindole (delta receptors) rather than against those labeled by [H-3]DAMGO (mu receptors) or [H-3]U69, 593 kappa receptors) in mouse whole-brain assays. The ratios of the calculated K-i values for SNC 80 at mu/delta and kappa/delta sites were 495- and 248-fold, respectively, which indicates a significant degree of delta selectivity for this compound in radioligand binding assays. SNC 80 produced dose- and time-related antinociception in the mouse warm-water tail-flick test after i.c.v., i.th, and i.p. administration. The calculated A(50) values (and 95% C.I.) for SNC 80 administered i.c.v., i.th, and i.p. were 104.9 (63.7-172.7) nmol, 69 (51.8-92.1) nmol and 57 (44.5-73.1) mg/kg, respectively. The i.c.v, administration of SNC 80 also produced dose- and time-related antinociception in the hot-plate test, with a calculated A(50) value (and 95% C.I.) of 91.9 (60.3-140.0) nmol. Intraperitoneal SNC 80 antinociception was antagonized by pretreatment with i.c.v. naloxone (3 nmol), with i.c.v. or i.th. N,N-diallyl-Tyr-(Aib)(2)-Phe-Leu-OH(Aib = alpha-amino isobutyric acid) (4.4 nmol) or with i.p. naltrindole (20 mg/kg), but not i.c.v. or i.th. beta-FNA (18.8 nmol at -24 hr). Furthermore, the antinociceptive effects of i.c.v. SNC 80 were antagonized by i.c.v, pretreatment with either [D-Ala(2),Leu(5),Cys(6)]enkephalin (a putative delta(1) antagonist) or [D-Ala(2), Cys(4)]deltorphin (a putative delta(2) antagonist), but not by beta-funaltrexamine (a mu antagonist). This suggests that the antinociceptive actions of SNC 80 are produced via both opioid delta(1) and delta(2), but not mu, receptors. On the basis of its profile in vivo and in vitro, SNC 80 is perhaps the first highly selective, nonpeptidic and systemically active opioid delta agonist. SNC 80 promises to be a useful compound for the exploration of opioid delta-receptor pharmacology and provides a basis for the further identification of selective nonpeptidic delta ligands.

TI HOW FEE AND INSURANCE CHANGES COULD AFFECT DENTISTRY - RESULTS FROM A
MICROSIMULATION MODEL
SO JOURNAL OF THE AMERICAN DENTAL ASSOCIATION
LA English
DT Article
AB Dentists have become concerned about the possible impact of reductions in dental insurance coverage. The authors used a microsimulation model of the dental sector to assess the potential impact of reductions in the percentage of Americans with dental insurance, in universal dental insurance coverage for children and in fees paid to dentists for their services. The model predicted that reductions in dental insurance coverage would reduce per capita dental expenditures, but that the impact would not be large. Fee reductions had the greatest impact on dental expenditures of any change simulated by the model.

ID INCONTINENCE; QUESTIONNAIRE; POPULATION; SYMPTOMS; PATTERNS; SEVERITY;
IMPACT; WOMEN; HOME
AB OBJECTIVE: The goal of this study was to estimate the prevalence and correlates of difficulty holding urine among a population of community-dwelling older people.
DESIGN: Population-based cross-sectional study.
SUBJECTS: A population census identified all residents aged 65 years and older residing in East Boston, Massachusetts, in 1982.
MEASURES: Data collected via in-home interviews were used to estimate the prevalence of difficulty holding urine and to provide information regarding potential, correlates of urinary difficulty.
RESULTS: Of the 3809 study participants (85% response rate), 28% reported having ''difficulty holding urine until they can get to a toilet'' at least some of the time, and 8% reported difficulty ''most'' or ''all of the time.'' Difficulty was associated with age and sex; 44% of women and 34% of men reported some difficulty (P <.001), and 9% of women and 6% of men (P <.001) reported difficulty most or all of the time. For respondents aged 65 to 74 years, 40% reported some difficulty, compared with 47% of those aged 85 and older (P-trend <.001); difficulty most or all of the time was reported by 6% of those aged 65 to 74 and 12% of those aged 85 and older (P-trend <0.01) Difficulty holding urine was associated with important health and functional measures including depression, stroke, chronic cough, night awakening, fecal incontinence, problems with activities of daily living, decreased frequency and ease in getting out of the house, and poor self-perception of health.
CONCLUSIONS: Difficulty holding urine is a prevalent condition among older people living in the community and is associated highly with a number of health conditions and functional problems.

SO JOURNAL OF THE AMERICAN GERIATRICS SOCIETY
LA English
DT Article
ID ASSISTED SUICIDE
AB OBJECTIVE: To survey physicians to determine whether sociodemographic and practice-related variables are predictive of their attitudes toward suicide.
DESIGN: Mailed questionnaire survey.
SETTING: Monroe County, New York.
PARTICIPANTS: A 50 percent random sample of practicing primary care physicians. Of 186 potential respondents, 114 (61.3%) physicians returned questionnaires.
MEASUREMENT: In addition to age and gender, independent variables included medical specialty, practice composition defined in terms of patient age, and textbook knowledge of depression and suicide. The dependent variable, attitude toward suicide, was measured using four standard opinion survey questions and six items based on a case vignette. Dependent variables were rated on a Likert-type scale and subsequently dichotomized for use in logistic regression analysis.
RESULTS: Approximately 61 percent of the respondents believe that suicide can be rational under certain circumstances, 51 percent believe that physicians should not assist suicides under any circumstances, and 31 percent support legalization of assisted suicide under certain circumstances. Regression analyses revealed that gender was a significant predictor for three of the ten attitude items. Medical specialty, clinical and epidemiological knowledge of depression and suicide, and physician age significantly predicted one attitude item.
CONCLUSIONS: These results suggest that physicians' attitudes toward suicide are multidetermined. Although gender, age, medical specialty, and knowledge of depression and suicide predict certain attitudes, the logistic regression analyses were not highly successful in predicting respondents' attitudes. Given the power of physicians to command public attention and to influence public and legal opinion, it is vital that future research continue to explore the determinants of physicians' attitudes toward self-determined death.

AB An infectious molecular clone of human T-cell leukemia virus type I (HTLV-I) was derived from an HTLV-I-transformed rabbit T-cell line, RH/K30, obtained by coculture of rabbit peripheral blood mononuclear cells (PBMC) with the human HTLV-I-transformed cell line MT-2. The RH/K30 cell line contained two integrated proviruses, an intact HTLV-I genome and an apparently defective provirus with an in-frame stop codon in the env gene. A genomic DNA fragment containing the intact HTLV-I provirus was cloned into bacteriophage lambda (K30 phi) and subcloned into a plasmid vector (K30p). HTLV-I p24(gag) protein was detected in culture supernatants of human and rabbit T-cell and fibroblast lines transfected with these clones, at levels comparable to those of the parental cell line RH/K30. Persistent expression of virus was observed in one of these lines, RL-5/K30p, for more than 24 months. Biologic characterization of this cell line revealed the presence of integrated HTLV-I provirus, spliced and unspliced mRNA transcripts, and typical extracellular type C retrovirus particles. As expected, these virus particles contained HTLV-I RNA and reverse transcriptase activity. The transfected cells also expressed surface major histocompatibility complex class II, whereas no expression of this molecule was detected in the parental RL-5 cell line. Virus was passaged by cocultivation of irradiated RL-5/K30p cells with either rabbit PBMC or human cord blood mononuclear cells, demonstrating in vitro infectivity. The virus produced in these cells was also infectious in vivo, since rabbits injected with RL-5/K30p cells became productively infected, as evidenced by seroconversion, amplification of HTLV-I-specific sequences by PCR from PBMC DNA, and virus isolation from PBMC. Availability of infectious molecular clones will facilitate functional studies of HTLV-I genes and gene products.

AB The DNA of human parvovirus adeno-associated virus type 2 (AAV) integrates preferentially into a defined region of human chromosome 19. Southern blots of genomic DNA from latently infected cell lines revealed that the provirus was not simply inserted into the cellular DNA. Both, the proviral and adjoining cellular DNA organization indicated that integration occurred by a complex, coordinated process involving limited DNA replication and rearrangements. However, the mechanism for targeted integration has remained obscure. The two larger nonstructural proteins (Rep68 and Rep78) of AAV bind to a sequence element that is present in both the integration locus (P1) and the AAV inverted terminal repeat. This binding may be important for targeted integration. To investigate the mechanism of targeted integration, we tested the cloned integration site subfragment in a cell-free replication assay in the presence or absence of recombinant Rep proteins. Extensive, asymmetric replication of linear or open-circular template DNA was dependent on the presence of P1 sequence and Rep protein. The activities of Rep on the cloned P1 element are analogous to activities on the AAV inverted terminal repeat. Replication apparently initiates from a 3'-OH generated by the sequence specific nicking activity of Rep. This results in a covalent attachment between Rep and the 5'-thymidine of the nick The complexity of proviral structures can be explained by the participation of limited DNA replication facilitated by Rep during integration.

AB Chronically human immunodeficiency virus type 1 (HIV-1) strain IIIB-infected human TH4-7-5 astrocytoma cells show low-level virus production. Cocultivation of TH4-7-5 cells,vith myelomonocytic cells led to active virus production in these target cells after a lag period, indicating cell-determined restriction of virus replication in the glial cells. HIV-1 transcript patterns of TH4-7-5 cells contained only a small proportion of Rev-dependent mRNA species, mimicking a Rev-negative phenotype despite the presence of rev mRNAs and protein. Sequencing of the single provirus integrated in TH4-7-5 cells demonstrated that the rev gene and the Rev-responsive element are intact. These results suggested inhibited function of the Rev-regulatory unit in these astrocytoma cells. Transfection of TH4-7-5 cells with a Rev expression plasmid resulted in weak or no induction of proviral p24(gag) antigen levels compared with the dramatic increase observed in Rev-permissive HeLa cells. Immunofluorescence analysis of TH4-7-5 cells transfected with a rev-expressing plasmid revealed prominent cytoplasmic and nuclear-nucleolar localization of Rev, in contrast to the predominant nuclear-nucleolar localization pattern of Rev in HeLa cells. We conclude that restriction of virus production in TH4-7-5 cells is at least partially due to a block in Rev-dependent posttranscriptional regulation of HIV expression.

AB The mechanism of heparan sulfate (HS)-mediated human immunodeficiency virus type 1 (HIV-1) binding to and infection of T cells was investigated with a clone (H9h) of the T-cell line H9 selected on the basis of its high level of cell surface CD4 expression. Semiquantitative PCR analysis revealed that enzymatic removal of cell surface HS by heparitinase resulted in a reduction of the amount of HIV-1 DNA present in H9h cells 4 h after exposure to virus. Assays of the binding of recombinant envelope proteins to H9h cells demonstrated a structural requirement for an oligomeric form of gp120/gp41 for HS-dependent binding to the cell surface, The ability of the HIV-1 envelope to bind simultaneously to HS and CD4 was shown by immunoprecipitation of HS with either antienvelope or anti-CD4 antibodies from (SO42-)-S-35-labeled H9h cells that had been incubated with soluble gp140. Soluble HS blocked the binding of monoclonal antibodies that recognize the V3 and C4 domains of the envelope protein to the surface of H9 cells chronically infected with HIV-1(IIIB). The V3 domain was shown to be the major site of envelope-HS interaction by examining the effects of both antienvelope monoclonal antibodies and heparitinase on the binding of soluble gp140 to H9h cells.

AB We have isolated seven single-cell clones from an H9 culture infected with human immunodeficiency virus type 1 strain MN so that a stable producer of virus could be obtained. DNAs from these clones were examined by Southern blot analysis and found to contain between one and four proviruses per clone. One of these cell lines, Clone 4, produced high levels of replication-competent virus and contained two proviruses. Southern blot analysis of DNAs from Clone 4 revealed that, after extended culture, some of the cells had acquired additional proviruses, presumably by superinfection. Analysis of Clone 4 single-cell subclones isolated from a late-passage culture found that 14 out of 20 (70%) subclones were reinfected and that 8 out of 20 (40%) were reinfected more than once. Fluorescence-activated cell sorter analysis showed that surface CD4 levels on Clone 4 cells were appropriately down-regulated. Our results indicate that while there is significant interference to superinfection in the Clone 4 culture, it is not absolute and that superinfected cells accumulate in the culture over time in the presence of high virus exposure and extensive cell-to-cell contact. Given our data, it seems likely that superinfection can occur in vivo within the lymphoid reservoirs that harbor human immunodeficiency virus type 1 during the clinically latent period and may contribute to disease progression.

AB Antiviral cytotoxic T lymphocytes (CTL) may play a role in clearance of hepatitis C virus (HCV)-infected cells and thereby cause hepatocellular injury during acute and chronic HCV infection. The aim of this study was to identify HLA-A2.1-restricted HCV T-cell epitopes and to evaluate whether anti-HCV-specific CTL are present during chronic hepatitis C. Peripheral blood mononuclear cells from four HLA-A2-positive patients with chronic hepatitis C and from two individuals after recovery from HCV infection were tested against a panel of HCV-encoded peptides derived from different regions of the genome, including some peptides containing HLA-A2.1 binding moths. HLA-A2-negative patients,vith chronic hepatitis C as well as healthy HLA-A2-positive (anti-HCV-negative) donors served as controls. Peripheral blood mononuclear cells stimulated repeatedly with several HCV-encoded peptides (three in core, one in NS4B, and one in NS5B) yielded cytolytic responses. All four HLA-A2-positive patients with active infection had CTL specific for at least one of the identified epitopes, whereas two patients who had recovered from HCV infection had almost no CTL responses. Monoclonal antibody blocking experiments performed for two epitopes demonstrated a class I- and HLA-A2-restricted CTL response. CTL epitopes could partially be predicted by HLA-AZ, binding motifs and more reliably by quantitative HLA-A2.1 molecule binding assays. Most of the identified epitopes could also be produced via the endogenous pathway. Specific CTL against multiple, mostly highly conserved epitopes of HCV were detected during chronic HCV infection. This finding may be important for further investigations of the immunopathogenesis of HCV, the development of potential therapies against HCV on the basis of induction or enhancement of cellular immunity, and the design of vaccines.

AB Retroviruses contain a dimeric RNA consisting of two identical molecules of plus-strand genomic RNA. The structure of the linkage between the two monomers is not known, but they are believed to be joined near their 5' ends. Darlix and coworkers have reported that transcripts of retroviral RNA sequences can dimerize spontaneously in vitro (see, for example, E. Bieth, C. Gabus, and J. L. Darlix, Nucleic Acids Res. 18:119-127, 1990). As one approach to identification of sequences which might participate in the linkage, we have mapped sequences derived from the 5' 378 bases of Harvey sarcoma virus (HaSV) RNA which can dimerize in vitro. We found that at least three distinct regions, consisting of nucleotides 37 to 229, 205 to 272, and 271 to 378, can form these dimers. Two of these regions contain nucleotides 205 to 226; computer analysis suggests that this region can form a stem-loop with an inverted repeat in the loop. We propose that this hypothetical structure is involved in dimer formation by these two transcripts. We also compared the thermal stabilities of each of these dimers with that of HaSV viral RNA. Dimers of nucleotides 37 to 229 and 205 to 272 both exhibited melting temperatures near that of viral RNA, while dimers of nucleotides 271 to 378 are quite unstable. We also found that dimers of nucleotides 37 to 378 formed at 37 degrees C are less thermostable than dimers of the same RNA formed at 55 degrees C. It seems possible that bases from all of these regions participate in the dimer linkage present in viral RNA.

AB Cellular differentiation is thought to play an important role in the susceptibility of monocytic lineage cells to human immunodeficiency virus (HIV) infection as well as in their ability to support virus replication. In addition, virus replication in monocytes/macrophages has been demonstrated in vitro to be strongly modulated by several cytokines such as tumor necrosis factor alpha and granulocyte-macrophage colony-stimulating factor. The purpose of the present study was to investigate the interaction between cellular differentiation and cytokines in the regulation of HIV expression from chronically infected monocytic lineage cells. U1, a persistently HIV-infected promonocytic cell line, is characterized by low levels of virus expression which can be modulated by several cytokines. 1 alpha,-25-Dihydroxyvitamin D3 (Vit.D3), a well-known differentiating agent for myelomonocytic cells which has been previously reported to modulate HIV replication in other in vitro systems, induced maturation of U1 cells toward a macrophage-like phenotype, as demonstrated by the induction of the differentiation-associated cell surface markers CD14 and CD11b. Vit.D3-induced differentiation did not result in induction of HIV expression; however, when U1 cells were stimulated with tumor necrosis factor alpha in the presence of Vit.D3, a synergistic induction of cell differentiation and viral expression was demonstrated. In contrast, Vit.D3 suppressed the induction of HIV expression in U1 cells stimulated,vith gamma interferon, interleukin-6, and granulocyte-macrophage colony-stimulating factor, although synergy between Vit.D3 and these cytokines was observed in terms of cellular differentiation. These data suggest that differentiation of monocytic cells does not necessarily correlate with increased HIV expression.

In this study, microsatellite markers were used to localize the Rfv3 gene to a 20-centimorgan region of mouse chromosome 15 unlinked to immunoglobulin loci, T-cell receptor loci, or the major histocompatibility complex. Potential candidate genes for Rfv3 are several genes expressed in cells of the immune system and previously mapped to the same region, including a T-cell antigen gene, Ly6, and three cytokine receptor genes, IL2rb, IL3rb1, and IL3rb2.

AB Most strains of animal rotaviruses are able to agglutinate erythrocytes, and the surface protein VP4 is the virus hemagglutinin. To map the hemagglutination domain on VP4 while preserving the conformation of the protein, we constructed full-length chimeras between the VP4 genes of hemagglutinating (YM) and nonhemagglutinating (KU) rotavirus strains. The parental and chimeric genes were expressed in insect cells, and the recombinant VP4 proteins were evaluated for their capacity to agglutinate human type O erythrocytes. Three chimeric genes, encoding amino acids 1 to 208 (QKU), 93 to 208 (QC), and 93 to 776 (QYM) of the YM VP4 protein in a KU VP4 background, were constructed. YM VP4 and chimeras QKU and QC were shown to specifically hemagglutinate, indicating that the region between amino acids 93 and 208 of YM VP4 is sufficient to determine the hemagglutination activity of the protein.

AB We have carried out a comparison of cartilage degeneration that develops spontaneously with age in the Wistar and Fischer 344 rats, Young adult (6-month-old) Wistar rats were essentially free of any relevant lesion in the articular cartilage of the knee, Aged (24-month-old) Wistar rats had minimal to mild lesions found mainly in the medial tibial plateau, These lesions were indicated by a focal loss of toluidine blue staining and limited fibrillation. Approximately 68% of the old Wistar rats had some degree of pathologic change, In comparison, 100% of the Fischer 344 rats examined, both young and old, had cartilage degeneration, However, the severity of the lesions increased with age, These two rat strains have variable degrees of spontaneous age-associated cartilage degeneration and would be suitable for testing treatments to prevent or repair the cartilage damage.

AB The p53 tumor suppressor gene is frequently mutated within its evolutionarily conserved regions in a number of human cancers. Previous reports demonstrated mutations of this gene in both Burkitt's lymphoma and B cell chronic lymphocytic leukemia. However, dissimilar results were obtained in non-Hodgkin's lymphoma (NHL). In one study, no mutation was detected in 43 NHL tissues. A second study reported p53 mutations in eight (all with advanced stage disease) out of 48 tissues obtained from Japanese NHL patients. Using both immunoblotting and radio-immunoprecipitation, we detected mutant p53 proteins in nine out of 10 B cell lines established from NHL tissues. The mutations were confirmed by reverse transcription polymerase chain reaction-mediated single-strand conformational polymorphism (RT-PCR-SSCP) analysis in eight cell lines. The high frequency of p53 mutation in NHL B cell lines and the relatively low frequency of p53 mutations in fresh lymphoma tissue suggests that p53 gene alteration may play a role in lymphomagenesis and/or disease progression in a subset of B cell lymphomas and that the p53 mutation conveys a proliferative advantage on lymphoma cells that permits their in vitro growth.

AB A retrovirus, human T cell lymphotropic virus type 1 (HTLV-1), is an essential but not a sufficient aetiologic factor for tropical spastic paraparesis (TSP). Because some TSP patients have biological false positive tests for treponemal infections (BFP-STS), we used ELISA to study BFP-STS and anticardiolipin antibodies in 42 Jamaican TSP patients. The data indicate that in TSP anticardiolipin antibodies occur in about 26% of patients, are associated with biological false positive treponemal serology, are relatively restricted to the IgA isotype and may be induced by HTLV-1 or other non-treponemal infections.

AB Nine microsatellite loci were mapped to rat Chromosome (Chr) 7 by genetic linkage and somatic cell hybrid analysis. These loci include the gene encoding a member of the IID subfamily of cytochrome P450 (Cyp2d), a gene with repetitive sequences expressed during myotube formation (D7Arble), four anonymous loci, D7Arb81, D7Arb208, D7Arb569, D7Arb609a, and three DNA loci defined by MapPair(TM) markers R245, R513, and R1071. The nine loci were all identified by PCR-based microsatellite polymorphism analysis and were characterized in 40 F-2 intercross progeny of Fischer (F344/N) and Lewis (LEW/N) rats for segregation analysis. These markers formed a single linkage group spanning 76.8 cM with the following order and distances: D7Arb569-11.4 cM-D7Arb81-9.7 cM-R513-2.6 cM-Cyp2d-0.0 cM-R245-1.3 cM-D7Arble-10.4 cM-R1071-15.9 cM-D7Arb609a-15.4 cM-D7Arb208. Physical mapping of Cyp2d by somatic cell hybrid analysis allowed us to assign this linkage group to rat Chr 7. For each marker, two to six alleles were detected in a panel of 16 inbred rat strains (ACI/N, BN/SsN, BUF/N, DA/Bkl, F344/N, LER/N, LEW/N, LOU/MN, MNR/N, MR/N, SHR/N, SR/Jr, SS/Jr, WBB1/N, WBB2/N, WKY/N).

DE MELANOMA; METASTASIS; SCID MICE; SEX HORMONES
AB The liver metastasis formation of two human melanoma cell lines were compared in male and female SCID mice. The intrasplenic injection of both tumour lines resulted in a significantly higher number of liver metastases in male than in female mice; the incidence and weight of spleen tumours, as well as the incidence of metastases were similar. Both melanoma cell lines bound fluorescent oestradiol, progesterone and testosterone conjugates, and proved to be positive for oestrogen receptor-related protein by immunocytochemistry, These observations support the view that endocrine factors influence the progression of human melanomas. This SCID mouse model could be useful in studying the effects of hormonal manipulations on human melanoma metastases.

AB Extraintestinal strains of Escherichia coli possess a variety of virulence factors that enable them to cause disease. These strains express a group 2 capsular polysaccharide which is important in the pathogenic process. Extraintestinal strains evaluated to date are also capable of producing the group 1 capsular polysaccharide colanic acid. The blood isolate CP9 (O4/K54/H5) constitutively produces the group 2, K54 capsule but can be induced to produce colanic acid. In this report we assess whether colanic acid contributes to the pathogenesis of this extraintestinal pathogen. CP9 and its derivatives that are deficient in their ability to produce colanic acid (TR94), the K54 group 2 capsule +/- colanic acid (CP9.137, TR1374) and the O4 specific antigen +/- colanic acid (CP921,CP925) were used to test whether the group 1 capsule colanic acid conferred protection against the bactericidal effects of serum and recombinant bactericidal/permeability-increasing protein (rBPI-23) in vitro. Additionally, CP9, CP9.137 and TR94 were evaluated in the rat granuloma pouch, an in vivo model for localized infection, and. by intraperitoneal inoculation into mice, a systemic infection model. In summary, the inability of CP9 to produce colanic acid in the presence or absence of its K54 and O4 antigens had no effect on its ability to survive these host defenses in vitro and did not affect its virulence in these two in vivo models of infection.

AB Tumor-associated glycoprotein 72 is a high-molecular-weight sialomucin that is expressed selectively in various adenocarcinomas, including those of the prostate. We utilized the monoclonal antibodies B72.3 and CC49 to examine the expression of TAG-72 in high-grade prostatic intraepithelial neoplasia (PIN), localized adenocarcinomas (pathologic stages B and C), as well as matching primary and nodal lesions from patients with stage D adenocarcinomas. Immunoreactivity within PIN lesions was detected within 20 (87%) and 17 (74%) of 23 specimens immunostained with B72.3 and CC49, respectively. Benign epithelium and stromal tissue did not immunostain with either antibody at the concentrations tested. Immunostaining was detected within the malignant cells in 30 (77%) and 35 (90%) of 39 localized adenocarcinomas using B72.3 and CC49, respectively. Immunostaining was localized to the cytoplasm and cellular membranes of the malignant cells and within the lumen of malignant glands. Seven of 17 (41%) primary lesions from patients with stage D adenocarcinomas demonstrated immunoreactivity when stained with B72.3. Immunoreactivity was detected in 8 of 10 (80%) of these tissues immunostained with CC49. Within nodal lesions obtained from these patients, immunostaining was observed in 3 of 17 (18%) and 6 of 10 (60%) of the specimens immunostained with B72.3 and CC49, respectively. We used a semiquantitative technique to compare the extent of immunoreactivity among well-differentiated (Gleason score <6), moderately differentiated (Gleason 6-7), and poorly differentiated (Gleason score >7) tumors. We observed an inverse correlation of TAG-72 expression to Gleason scores. Furthermore, TAG-72 expression was reduced in the matching primary and metastatic lesions of stage D adenocarcinomas as compared to localized lesions. These findings demonstrate a phenotypic relationship of PIN to invasive adenocarcinomas and support the concept that PIN is a preinvasive neoplastic lesion. Furthermore, expression of TAG-72 may represent an early event in the neoplastic transformation of the prostatic epithelium. The data demonstrate a diminution in TAG-72 expression in poorly differentiated and advanced-stage prostatic adenocarcinomas.

AB To investigate the optimal cytologic method for detecting anal intraepithelial neoplasia, the quality and diagnostic findings in 117 conventionally prepared smears and 191 CYTYC Thin-Preps were compared, Samples were obtained with a dacron swab from subjects participating in a longitudinal study of gay or bisexual men known as the Study to Help the AIDS Research Effort (SHARE). The smear takers were general clinicians who had no experience in obtaining cytologic specimens from the anus. Smears were entirely satisfactory in 48 (41.0%) subjects, limited for interpretation in 41 (35.0%), and unsatisfactory in 28 (23.9%). CYTYC preparations were satisfactory in 158 (82.7%) cases and unsatisfactory in 33 (17.3%). Insufficient cellularity was the most frequent reason for both unsatisfactory smears and CYTYC preparations, but air drying artifact was present in nearly every smear. Squamous intraepithelial lesions (SILs) were detected in four (4.5%) smears compared to 53 (33.6%) CYTYC slides. The detection of SIL correlated with the presence of glandular and metaplastic cells in CYTYC preparations, but this association disappeared if only satisfactory specimens were considered, In conclusion, CYTYC Thin-Preps were satisfactory twice as often as conventional smears (P < 0.005) and detected nearly eight times as many SILs (P < 0.005).

AB Leishmania donovani and related trypanosomatid protozoa possess an externally oriented surface membrane enzyme capable of hydrolyzing both 3'-nucleotides and nucleic acids. By virtue of these activities, this 3'-nucleotidase/nuclease (3'-NT/Nu), previously shown to be analogous to fungal and plant class-I single-strand-specific nucleases, is thought to play a critical role in the salvage of purines, essential for the survival of these organisms. The 43-kDa 3'-NT/Nu was purified from L. donovani promastigotes and trypsin treated. Four of the released tryptic peptide fragments yielded amino-acid sequence information (Pept-1 to Pept-4) which provided the basis for the preparation of oligonucleotide primers used for PCR amplification of an approx. 300-bp DNA fragment. This fragment was cloned, sequenced and used to probe a genomic L. donovani cosmid library. Nucleotide sequence analysis of a 4.5-kb SmaI fragment, isolated from a cosmid clone, revealed an open reading frame (ORF) of 1434 nt encoding a 477-amino-acid protein. Pept-1 to Pept-4 were mapped onto the ORF-deduced protein sequence. Peptides corresponding to Pept-1 to Pept-4 were synthesized and used to immunize rabbits. The resulting anti-peptide antibodies recognized the 43-kDa protein on Western blots and immunoprecipitated the native 3'-nucleotidase activity from L. donovani membrane extracts. Further, the ORF-deduced protein shared significant sequence identity with the S1 and P1 fungal nucleases of Aspergillus oryzae and Penicillium citrinum, respectively. Cumulatively, these results demonstrated that the ORF corresponded to a gene for the L, donovani 3'-nucleotidase/nuclease. In Northern blots a nucleotide probe specific for the 3'-NT/Nu gene hybridized to a single 2.5-kb messenger RNA. Results of Southern blot analyses were consistent with the 3'-NT/Nu being encoded by a single copy gene. These data constitute the first report of the gene for this unique trypanosomatid surface membrane enzyme.

AB The PAR subfamily of basic leucine zipper (bZIP) factors comprises three proteins (VBP/TEF, DBP, and HLF) that have conserved basic regions flanked by proline- and acidic-amino-acid-rich (PAR) domains acid functionally compatible leucine zipper dimerization domains. We show that VBP preferentially binds to sequences that consist of abutted GTAAY half-sites (which we refer to as PAR sites) as well as to sequences that contain either a C/EBP half-site (GCAAT) or a CREB/ATF half-site (GTCAT) in place of one of the PAR half-sites. Since the sequences that we describe as PAR sites and PAR-CREB/ATF chimeric sites, respectively, were both previously described as high-affinity binding sites for the E4BP4 transcriptional repressor, we infer that these sequences may be targets for positive and negative regulation. Similarly, since the sequences that we describe as PAR-C/EBP and PAR-CREB/ATF chimeric sites are known to be high-affinity binding sites for C/EBP acid CREB/ATF factors, respectively, we infer that these sites may each be targets for multiple subfamilies of bZIP factors. To gain insights regarding the molecular basis for the binding-site specificity of PAR factors, we also carried out an extensive mutational analysis of VBP. By substituting five amino acid residues that differ between the Drosophila giant bZIP factor and the vertebrate PAR bZIP factors, we show that the fork region, which bridges the basic and leucine zipper domains, contributes to half site sequence specificity. In addition, we report that at least two domains amino terminal to the core basic region are required for VBP to bind to the Full spectrum of PAR target sites. Thus, whereas direct base contacts may be restricted to basic-region residues (as indicated by GCN4-DNA crystal structures), several other domains also influence the DNA-binding specificity of PAR bZIP proteins.

AB Nearly 1 million Alu elements in human DNA were inserted by an RNA-mediated retroposition-amplification process that clearly decelerated about 30 million years ago. Since then, Alu sequences have proliferated at a lower rate, including within the human genome, in which Alu mobility continues to generate genetic variability. Initially derived from 7SL RNA of the signal recognition particle (SRP), Alu became a dominant retroposon while retaining secondary structures found in 7SL RNA. We previously identified a human Alu RNA-binding protein as a homolog of the 14-kDa Alu-specific protein of SRP and have shown that its expression is associated with accumulation of 3'-processed Alu RNA. Here, we show that in early anthropoids, the gene encoding SRP14 Alu RNA-binding protein was duplicated and that SRP14-homologous sequences currently reside on different human chromosomes. In anthropoids, the active SRP14 gene acquired a GCA trinucleotide repeat in its 3'-coding region that produces SRP14 polypeptides with extended C-terminal tails. A C --> G substitution in this region converted the mouse sequence CCA GCA to GCA GCA in prosimians, which presumably predisposed this locus to GCA expansion in anthropoids and provides a model for other triplet expansions. Moreover, the presence of the trinucleotide repeat in SRP14 DNA and the corresponding C-terminal tail in SRP14 are associated with a significant increase in SRP14 polypeptide and Alu RNA-binding activity. These genetic events occurred during the period in which an acceleration in Alu retroposition was followed by a sharp deceleration, suggesting that Alu repeats coevolved with C-terminal variants of SRP14 in higher primates.

AB Recent studies have provided evidence of crosstalk between steroid receptors and cyclic AMP (cAMP) signalling pathways in the regulation of gene expression. A synergism between intracellular phosphorylation inducers and either glucocorticoids or progestins has been shown to occur during activation of the mouse mammary tumor virus (MMTV) promoter. We have investigated the effect of 8-Br-cAMP and okadaic acid, modulators of cellular kinases and phosphatases, on the hormone-induced activation of the MMTV promoter in two forms: a transiently transfected template with a disorganized, accessible nucleoprotein structure and a stably replicating template with an ordered, inaccessible nucleoprotein structure. Both okadaic acid and 8-Br-cAMP synergize significantly with either glucocorticoids or progestins in activating the transiently transfected MMTV template. In contrast, 8-Br-cAMP, but not okadaic acid, is antagonistic to hormone-induced activation of the stably replicating MMTV template. Nuclear run-on experiments demonstrate that this inhibition is a transcriptional effect on both hormone-induced transcription and basal transcription. Surprisingly, 8-Br-cAMP does not inhibit glucocorticoid-induced changes in restriction enzyme access and nuclear factor 1 binding. However, association of a complex with the TATA hox region is inhibited in the presence of 8-Br-cAMP. Thus, cAMP treatment interferes with the initiation process but does not inhibit interaction of the receptor with the template. Since the replicated, ordered MMTV templates and the transfected, disorganized templates show opposite responses to 8-Br-cAMP treatment, we conclude that chromatin structure can influence the response of a promoter to activation of the cAMP signalling pathway.

AB The cytoplasmic serine-threonine protein kinase coded for by the e-akr proto-oncogene features a protein kinase C-like catalytic domain and a unique NH2-terminal domain (AH domain). The AH domain is a member of a domain superfamily whose prototype was observed in pleckstrin (pleckstrin homology, or PH, domain). In this communication, we present evidence that the AH/PH domain is a domain of protein-protein interaction which mediates the formation of Akt protein complexes. The interaction between c-akt AH/PH domains is highly specific, as determined by the failure of this domain to bind AKT2. The AH/PH domain-mediated interactions depend on the integrity of the entire domain. Akt molecules with deletions of the NH2-terminal portion (amino acids 11 to 60) and AH/PH constructs with deletions of the C-terminal portion of this domain (amino acids 107 to 147) fail to interact with c-akt. To determine the significance of these findings, we carried out in vitro kinase assays using Akt immunoprecipitates from serum-starved and serum-starved, platelet-derived growth factor-stimulated NIH 3T3 cells. Addition of maltose-binding protein-AH/PH fusion recombinant protein, which is expected to bind Akt, to the immunoprecipitates from serum-starved cells induced the activation of the Akt kinase.

AB Positional cloning of rare disease genes depends on the availability of highly polymorphic markers near the disease loci. The most abundant class of polymorphic markers in the human genome is CA-repeats. We have developed a strategy for the rapid isolation of highly polymorphic CA-repeats from YAC clones. Total DNA of yeast clones containing partly overlapping YACs is digested with frequent cutter restriction enzymes, blotted and hybridized with a poly(CA/GT) probe under high stringency conditions that enable preferential detection of long CA-repeats. The repeats detected in this way are isolated by PCR using vectorette linkers, sequenced, and appropriate flanking markers are constructed for genotyping, All of the CA-repeats identified using this approach were highly polymorphic. This simple and rapid approach should allow the development of highly polymorphic markers at any genomic region cloned in YACs.

AB Neuronal peptides exert neurohormonal and neurotransmitter (neuromodulator) functions in the central nervous system (CNS). Besides these functions, a group of neuropeptides may have a capacity to create cell proliferation, growth, and survival. Axotomy induces transient (1-21 d) - upregulation of synthesis and gene expression of neuropeptides, such as galanin, corticotropin releasing factor, dynorphin, calcitonin gene-related peptide, vasoactive intestinal polypeptide, cholecystokinin, angiotensin II, and neuropeptide Y. These neuropeptides are colocalized with ''classic'' neurotransmitters (acetylcholine, aspartate, glutamate) or neurohormones (vasopressin, oxytocin) that are downregulated by axotomy in the same neuronal cells. It is more likely that neuronal cells, in response to axotomy, increase expression of neuropeptides that promote their survival and regeneration, and may downregulate substances related to their transmitter or secretory activities.

AB We have been studying the molecular mechanism of neuronal differentiation through which the multipotent precursor becomes limited to the final transmitter phenotype. Here we focused on the role of the 5' proximal regulatory cassette (-190; +53 bp) of the rat enkephalin (rENK) gene in the developmental regulation of the enkephalin phenotype. Several well characterized cis-elements, including AP2, CREB, NF1, and NFkB, reside on this region of the rENK gene. These motifs were sufficient to confer activity-dependent expression of the gene during neuro-differentiation when it was tested using transient transfection assays of primary developing spinal cord neurons treated with tetrodotoxin (TTX). This region was then used as a DNA probe in mobility shift assays, with nuclear proteins derived from phenotypically and ontogenetically distinct brain regions. Only a few low abundance protein-DNA complexes were detected and only with nuclear proteins derived from developing but not from adult brain. The spatiotemporal pattern of these complexes did not show correlation with enkephalin expression which was assessed by RT-PCR. We employed synthetic probes corresponding to consensus as well as ENK-specific sequences of the individual motifs to identify the nature of the observed bands. Although both consensus NF1 and enkCRE1(NF1) formed complexes with nuclear proteins derived from the striatum and cortex at various ages, the appearance of the bands was not correlated with ENK expression. Surprisingly, no complexes were detected if other ENK-specific motifs were used as probes. We also tested nuclear extracts derived from forskolin-induced and control C6 glioma cells, again using the whole proximal regulatory cassette as well as individual motifs. These experiments showed the formation of elaborate protein-DNA bands. There was no direct correlation between the appearance of bands and forskolin-induced ENK expression. Unexpectedly, all ENK-specific motifs formed specific and highly abundant protein-DNA complexes when nuclear extracts from the human tumor cell line (HeLa), which does not express ENK, were used. Based on these observations, we concluded that:
1. Interactions between the proximal regulatory cassette and additional probably far distant regions of the rENK gene and their binding proteins may be necessary to confer developmentally regulated, cell-specific expression of the ENK gene; and
2. Inducibility of the gene by common cis-elements can be governed by this region; however, the cell-specificity of the induction remains elusive.

AB The iodine-125 analog of the dopaminergically selective cocaine analog 3 beta-(4-iodophenyl)tropane-2 beta-carboxylic acid isopropyl ester (RTI-121) was evaluated as a probe for the dopamine transporter in rat striatum. Saturation and kinetic studies indicated that [I-125]RTI-121 binds to both high and low affinity components. The K-d of the high affinity component was 0.14 +/- 0.01 nM (mean +/- standard error), whereas the low affinity component demonstrated an affinity of 1.59 +/- 0.09 nM. The corresponding numbers of striatal binding sites labeled by [I-125]RT1-121 were 295 +/- 6 and 472 +/- 59 pmol/g of tissue (original wet weight), respectively. Intrastriatal injections of 6-hydroxydopamine eliminated >90% of specific [I-125]RTI-121 binding in the striatum. The pharmacological profile of specific [I-125]RTI-121 binding in the rat striatum was consistent with that of the dopamine transporter. There was a strong (r = 0.98, p < 0.0001) correlation between the potencies of drugs that displaced specific [I-125]RTI-121 binding and the potencies of these drugs to inhibit the uptake of [H-3]dopamine. In contrast, no correlation was found for the potencies of drugs to inhibit the uptake of either [H-3]norepinephrine or [H-3]serotonin. Autoradiographs produced using [I-125]RT1-121 demonstrated a distribution of label consistent with the distribution of dopaminergic neurons in rat brain. Because of its high affinity and high selectivity for the dopamine transporter, [I-125]RTI-121 may be an extremely useful ligand for the dopamine transporter.

AB A major obstacle to understanding AIDS is the lack of a suitable small animal model for studying HIV-1 infection and the subsequent development of AIDS, and for testing diagnostic, therapeutic, and preventive modalities. Our goal is to produce a rabbit model for the study of AIDS. Here we report on the generation of transgenic rabbits that express the human CD4 (hCD4) gene. The transgene, which contains the coding region for hCD4 and approximately 23 kb of sequence upstream of the translation start site, was used previously to direct hCD4 expression on the surface of CD4(+) T cells of transgenic mice (Gillespie et al., 1993: Mol Cell Biol 13:2952-2958). The hCD4 transgene was detected in five males and two females derived from the microinjection of 271 rabbit embryos. Both hCD4 RNA and protein were expressed in peripheral blood lymphocytes (PBLs) from all five males but neither of the females. Human CD4 was expressed on PBLs from F-1 offspring of all-founder males. T-cell subset analysis revealed that hCD4 expression was restricted to rabbit CD4 (rCD4) expressing lymphocytes; mature rCD4(-)rCD8(+) lymphocytes did not express hCD4. In preliminary studies, PBLs from hCD4 transgenic rabbits produced greater amounts of HIV-1 p24 core protein following HIV-I infection in vitro than HIV-1 p24 antigen in nontransgenic rabbit infected cultures. These results extend to rabbits our previous observation that this transgene contains the sequence elements required for high-level expression in the appropriate cells of transgenic mice. Furthermore, these and previous studies demonstrating that expression of hCD4 protein enhances HIV-I infection of rabbit T cells in vitro, coupled with reports that normal, nontransgenic rabbits are susceptible to HIV-1 infection, suggests that the hCD4 transgenic rabbits described herein will have an increased susceptibility to HIV-1 infection. In vivo HIV-1 infection studies with these rabbits are under way. (C) 1995 Wiley-Liss, Inc.

AB Ethylene oxide (ETO) is an important industrial intermediate used extensively in the production of ethylene glycol, as a fumigant, and as a sterilant of choice for various medical devices. The mutagenicity of ETO was studied for the induction of specific-locus mutations in the adenine-3 (ad-3) region of a two-component heterokaryon (H-12) of Neurospora crassa. The objectives of these studies with ETO were to rank its mutagenic potency and to compare its mutational spectrum for induced specific-locus mutations with other chemical mutagens in this lower eukaryotic organism. Specific-locus mutations in the ad-3 region of heterokaryon H-12 result from gene/point mutations at the closely linked ad-M and ad-3B loci, multilocus deletion mutations and multiple-locus mutations. These major genotypic classes are similar to the types of specific-locus mutations that can be detected in higher organisms. Conidial suspensions of H-12 were treated with five different concentrations of ETO (0.1-0.35%) for 3 h at 25 degrees C. Control and ETO-treated conidial suspensions were used to obtain dose-response curves for inactivation as well as the overall induction of ad-3 forward mutations using a non-selective method based on pigment accumulation rather than a requirement for adenine. The results from these experiments are: (1) the slope of the dose-response curve for ETC-induced specific-locus mutations in the ad-3 region is 1.49+/-0.07, and (2) the maximum forward-mutation frequency fell between 10 and 100 ad-3 mutations per 10(6) survivors; therefore, ETO is a moderate mutagen. Classical genetic tests were used to characterize the ETO-induced ad-3 mutations from each of two treatments (0.25 and 0.35%). The overall data base demonstrates that ETC-induced ad-3 mutations result from a high percentage (96.9%) of gene/point mutations at the ad-3A and ad-3B loci, as well as from a low percentage (3.1%) of multilocus deletion mutations. The mutagenic activity of ETO is compared with the mutagenic specificity of other chemical mutagens and carcinogens in the ad-3 forward-mutation assay in Neurospora. The utilization of the Neurospora specific-locus data on ETO and those from experiments in the mouse and Drosophila, by others, is discussed far genetic risk assessment of germ-cell effects resulting from human exposure to ETO in the workplace.

AB Some chemical carcinogens localize preferentially in mitochondrial DNA (mtDNA) when compared with genomic DNA (gDNA). Here we compare the ability of cisplatin (cis-diamminedichloroplatinum[II]) to induce DNA adducts in both genomic and mtDNA of Chinese hamster ovary (CHO) cells in culture. Cytotoxicity was examined by cell survival 4, 8 and 24 h after exposure to 50 mu M cisplatin. Cisplatin-DNA adducts were measured in DNA from nuclear and mitochondrial fractions by dissociation-enhanced lanthanide fluoroimmunoassay (DELFIA), a sensitive competitive microtiter-based immunoassay utilizing antiserum elicited against cisplatin-modified DNA. An additional comparison of cisplatin-DNA binding in both compartments was performed by immunoelectron microscopy using the cisplatin-DNA antiserum and colloidal gold. DELFIA analysis of cisplatin-DNA adducts in gDNA and mtDNA showed a six-fold higher incorporation of drug into mtDNA as compared to gDNA. Morphometric studies of colloidal gold distribution in photomicrographs of CHO cells showed mtDNA to contain a four-fold higher concentration of cisplatin as compared to nuclear DNA. Therefore, both methods demonstrated a preferential binding of cisplatin to mtDNA versus gDNA.

AB The technique of positional cloning has become a familiar component of modern human genetics research. After a halting start in the mid-1980s, the number of disease genes succumbing to cloning efforts based solely on pinpointing their position in the genome is growing exponentially. More than 40 genes have been identified so far. But the positional candidate approach, which combines knowledge of map position with the increasingly dense human transcript map, greatly expedites the search process and will soon become the predominant method of disease gene discovery. The challenge ahead is to apply such methods to identifying genes involved in complex polygenic disorders.

ID CARCINOMA
AB Overexpression of amplified genes is often associated with the acquisition of resistance to cancer therapeutic agents in vitro. We have identified a similar molecular mechanism in vivo for endocrine treatment failure in human prostate cancer which involves amplification of the androgen receptor (AR) gene. Comparative genomic hybridization shows that amplification of the Xq11-q13 region (the location), is common in tumours recurring during androgen deprivation therapy. We found high-level AR amplification in seven of 23 (30%) recurrent tumours, but in none of the specimens taken from the same patients prior to therapy. Our results suggest that AR amplification emerges during androgen deprivation therapy by facilitating tumour cell growth in low androgen concentrations.

AB The BRCA1 gene on chromosome 17q21 is responsible for an autosomal dominant syndrome of increased susceptibility to breast and ovarian cancer but no somatic mutations in tumours have yet been described. To study the potential role of BRCA1 in sporadic carcinogenesis, we analysed the genomic DNA of tumour and normal fractions of 47 ovarian cancers for mutations in BRCA1 using the single-strand conformation polymorphism technique. We now describe somatic mutations in the DNA of four tumours which also had loss of heterozygosity (LOH) at a BRCA1 intragenic marker. Our data support a tumour suppressor mechanism for BRCA1; somatic mutations and LOH may result in inactivation of BRCA1 in at least a small number of ovarian cancers.

AB Rhesus macaques were immunized with attenuated vaccinia or canarypox human immunodeficiency virus type 1 (HIV-1) recombinants and boosted with HIV-1 protein subunits formulated in alum. Following challenge with HIV-2(SBL6669), three out of eight immunized macaques resisted infection for six months and another exhibited significantly delayed infection, whereas all three naive controls became infected. Immunizations elicited both humoral and cellular immune responses; however, no clear correlates of protection were discerned. Although more extensive studies are now called for, this first demonstration of cross-protection between HIV-1 and -2 suggests that viral variability may not be an insurmountable problem in the design of a global AIDS vaccine.

AB An HIV-1-seropositive volunteer was infused with an expanded autologous cytotoxic T lymphocyte (CTL) clone directed against the HIV-1 nef protein. This clone was adoptively transferred to determine whether supplementing CTL activity could reduce viral load or improve clinical course. Unexpectedly, infusion was followed by a decline in circulating CD4(-) T cells and a rise in viral load. Some of the HIV isolates obtained from the plasma or CD4(-) cells of the patient were lacking the nef epitope. These results suggest that active CTL selection of viral variants could contribute to the pathogenesis of AIDS and that clinical progression can occur despite high levels of circulating HIV-1-specific CTLs.

AB HIV protease is a homodimeric protein whose activity is essential to viral function. We have investigated the molecular dynamics of the HIV protease, thought to be important for proteinase function, bound to high affinity inhibitors using NMR techniques. Analysis of N-15 spin refaxation parameters, of all but 13 backbone amide sites, reveals the presence of significant internal motions of the protein backbone. In particular, the flaps that cover the proteins active site of the protein have terminal loops that undergo large aCnpIitude motions on the ps to ns time scale, while the tips of the flaps undergo a conformational exchange on the mu s time scale. This enforces the idea that the flaps of the proteinase are flexible structures that facilitate function by permitting substrate access to and product release from the active site of the enzyme.

AB The NMR solution structure of the oligomerization domain of the tumour suppressor p53 (residues 319-360) has been refined. The structure comprises a dimer of dimers, oriented in an approximately orthogonal manner. The present structure determination is based on 4,472 experimental NMR restraints which represents a three and half fold increase over our previous work in the number of NOE restraints at the tetramerization interface. A comparison with the recently solved 1.7 Angstrom resolution X-ray structure shows that the structures are very similar and that the average angular root-mean-square difference in the interhelical angles is about 1 degrees. The results of recent extensive mutagenesis data and the possible effects of mutations which have been identified in human cancers are discussed in the light of the present structure.

TI FLAP OPENING IN HIV-1 PROTEASE SIMULATED BY ACTIVATED MOLECULAR-DYNAMICS
SO NATURE STRUCTURAL BIOLOGY
LA English
DT Article
ID INHIBITOR; COMPLEX
AB We have used an 'activated' molecular dynamics approach to simulate flap opening in HIV-1 protease. An initial impulse for flap opening was provided by applying harmonic constraints to non-flap residues. After an initial 'melting' phase, the two beta-hairpin structures that constitute the flaps opened to a 25 Angstrom gap within 200 ps of simulation. Analysis of backbone torsion angles suggests that flap opening is related to conformational changes at Lys 45, Met 46, Gly 52 and Phe 53. In contrast, similar molecular dynamics simulations on the M46l mutant, which is associated with drug resistance, indicates that this mutation stabilizes the flaps in a dosed conformation.

AB The possible role of angiotensin II (AII) in the control of the hypothalamic-pituitary-adrenal (HPA) axis was studied in the rat by examining the regulation and cellular localization of AII receptors in the paraventricular nucleus (PVN) of the hypothalamus and the effect of AII on corticotropin-releasing hormone (CRH) and vasopressin (VP) mRNA levels. In situ hybridization studies using cRNA S-35-labelled probes showed that while type 1 AII receptor (AT(1)) mRNA levels were high in the periventricular and parvicellular pars of the PVN, only very low levels were present in the magnocellular pars. A similar distribution of AT(1) receptor binding in the periventricular, parvicellular and magnocellular divisions of the PVN was observed in autoradiographic studies in hypothalamic sections labelled with I-125[Sar(1),Ile(8)]AII. In addition, AII receptor binding was clearly evident in nerve fibers adjacent to the PVN. Double-labelling hybridization using digoxigenin-labelled CRH, VP and oxytocin probes and S-35-labelled AT(1) receptor cRNA probes showed AT(1) receptor mRNA in cells stained for CRH mRNA, but not in VP or oxytocin cells. Four hours after a single intracerebroventricular (i.c.v.) injection of 50 ng AII in conscious rats, CRH mRNA levels in the PVN were increased by 43%, similar to the increases observed following acute stress by intraperitoneal (i.p.) injection of 1.5 M NaCl (76%). On the other hand, while i.p. hypertonic saline injection increased VP mRNA levels by 29% in the PVN and by 32% in the supraoptic nucleus, i.c.v. AII injection had no significant effect. The data strongly suggest that AII modulates CRH neurons directly through receptors in PVN perikarya, whereas regulation of magnocellular function is at least partly indirect via receptors associated with afferent innervation to the PVN. The data support a direct role for AII in the regulation of PVN function.

AB Parenchymatous intracerebral hemorrhage (ICH) is a serious, infrequent complication of thrombolytic therapy for acute myocardial, infarction. We studied the clinical and radiologic features, manner of presentation, associated factors, and temporal course in 23 patients with ICH associated with 150 mg or 100 mg recombinant tissue-type plasminogen activator (rt-PA) and heparin therapy for acute myocardial infarction in the Thrombolysis in Myocardial Infarction (TIMI) II Pilot and Randomized Clinical Trial. In TIMI II, 13 of the 23 ICH patients developed or maintained systolic blood pressure greater than or equal to 160 mm Hg or diastolic blood pressure greater than or equal to 90 mm Hg during the rt-PA infusion and before the onset of neurologic symptoms. Six patients (26%) had life-threatening ventricular arrhythmias, five before onset of neurologic symptoms. A decreased level of consciousness was the earliest neurologic abnormality in 15 (65%) and the most common initial physical finding (in 19, or 82%). Onset was usually gradual (70%), but time to maximal deficit was frequently (61%) within 6 hours of onset. The locations of the primary ICH sites were lobar in 16 (70%), thalamic in four (17%), and brainstem-cerebellum in three (13%), but the putamen was never the primary site. Multiple lobar hemorrhages occurred in six cases (26%). The timing and size of ICH was similar among patients treated with 150 mg rt-PA and 100 mg rt-PA. Brain CT demonstrated an arteriovenous malformation in one case. Four patients had hypofibrinogenemia, which was profound in three patients. Pathologic findings were available for five patients. Of these, three patients had cerebral amyloid angiopathy, and one had hemorrhagic transformation of an ischemic cerebral infarction found at autopsy. We conclude that ICH following rt-PA and heparin therapy for acute myocardial infarction presents as a distinctive clinical syndrome. Intracerebral bleeding after combined thrombolytic and antithrombotic therapy may be associated with cerebral amyloid angiopathy and other vascular lesions. Acute or persistent hypertension before or during rt-PA infusion, life-threatening ventricular arrhythmias, and hypofibrinogenemia, either alone or in combination, may play roles in some cases. Care should be exercised when considering thrombolytic therapy for patients with risk factors for ICH.

SO NEUROLOGY
LA English
DT Article
AB We assessed performance on selected tests of verbal memory in 48 patients who had undergone either anterior temporal lobectomy or selective amygdalo-hippocampectomy for the relief of pharmacologically intractable epilepsy. We related performance both to the side of surgical excision and to the presence or absence df abnormalities in the contralateral, unoperated, temporal lobe, as revealed by proton magnetic resonance spectroscopy (H-1 MRS) or T-2 relaxometry. There were abnormalities on the unoperated side detected by 1H MRS in 50% of the 34 patients who successfully underwent spectroscopy, and by T-2 relaxometry in 33% of the complete series of 48 patients. There was no systematic relationship between seizure outcome and the presence or absence of abnormalities on the unoperated side. Verbal memory deficits were present in patients with left-sided excision, regardless of whether there were abnormalities on the unoperated side. The patients with right-sided excision also had verbal memory deficits, but only in the group with magnetic resonance abnormalities on the contralateral (ie, left) side and only on delayed recall. The study extends previous findings on the role of the temporal lobes in memory and highlights the role of these new magnetic resonance techniques in relating cognitive processes to brain structures.

AB The flip and flop splice variants of AMPA receptors show strikingly different sensitivity to allosteric regulation by cyclothiazide; heteromers assembled from GluR-A and GluR-B also exhibit splice variant-dependent differences in efficacy for activation by glutamate and kainate. The sensitivity for attenuation of desensitization by cyclothiazide for homomeric GluR-A was solely dependent upon exchange of Ser-750 (flip) and Asn-750 (flop), and was unaffected by mutagenesis of other divergent residues. In contrast, substantial alteration of the relative efficacy of glutamate versus kainate required mutation of multiple residues in the flip/flop region. Modulation by cyclothiazide was abolished by mutation of Ser-750 to Gln, the residue found at the homologous site in kainate-preferring subunits, whereas introduction of Ser at this site in GluR6 imparted sensitivity to cyclothiazide.

AB The aim of the current study was to determine the degree to which patients with panic disorder develop tolerance to subjective and physiological effects of benzodiazepine after chronic treatment with alprazolam. Response to acute administration of diazepam was assessed in 19 panic disorder patients receiving chronic treatment with alprazolam and 23 untreated panic disorder patients. At baseline in the laboratory, the two groups did not differ in peak saccadic eye movement velocity, saccade latency, short-term memory, plasma cortisol and growth hormone concentrations, heart rate, and self-rated levels of sedation and anxiety. Compared with untreated patients, alprazolam-treated patients displayed significantly less diazepam-induced change in peak saccadic velocity, saccade latency, growth hormone secretion, memory, and self-rated levels of sedation. There was no difference between groups in diazepam effects on plasma cortisol concentrations or self-rated anxiety. Within alprazolam-treated patients, diazepam-induced slowing of peak saccade velocity was significantly inversely correlated with illness severity, as measured by reported panic attacks per week and severity of phobic avoidance, but not with alprazolam dose, blood level, or duration of treatment. Because the alprazolam-treated group reported more panic attacks per week than the untreated panic patients, treated patients were divided into those who were asymptomatic versus those with continuing panic attacks. The subgroup of nine alprazolam-treated subjects who were asymptomatic also showed significantly less diazepam effects than the group of untreated panic disorder patients, suggesting that overall group differences were at least partially attributable to the development of tolerance to selected benzodiazepine effects with chronic alprazolam treatment.

By use of an Amicon concentrator with reservoir, each of the steps necessary for the preparation of the conjugated drug may be performed in a single vessel. Advantages include reduced risk of metal, pyrogen and bacterial contamination; buffer exchanges are achieved rapidly and efficiently using a continuous dilution method. The radiolabeling efficiency, the radiochemical purity, the total immunoreactivity and the affinity of the final product have been evaluated in the production of CHXA-DTPA-chelate conjugated HuM195. The characteristics compare favorably to those achieved using our conventional synthetic methods.

ID MATERNAL SMOKING; BIRTH-WEIGHT; FETAL GROWTH; RISK-FACTORS; PREGNANCY
AB Objective: To estimate the effect of maternal cigarette smoking on birth weight, crown-heel length, and ten other neonatal anthropometric measurements.
Methods: Data are from a cohort study on risk factors for fetal growth retardation (FGR) in multiparous women conducted from December 1985 through October 1988. Information on smoking status was collected four times during pregnancy. Data analysis included 1205 singleton infants of women delivering at term. Neonatal anthropometric measurements were obtained within 48 hours of birth, including birth weight, crown-heel length, ponderal index, head and abdominal circumferences, arm length and circumference, femur length and thigh circumference, and triceps, thigh, and subscapular skinfold measurements. Analysis of covariance models were used to assess the independent effect of smoking on each neonatal measurement.
Results: Neonates born to women who reported smoking during the first trimester had a 0.6-1.9% reduction in most neonatal anthropometric measurements, resulting in an overall reduction of birth weight of 130 g (4%). Neonates born to women who continued to smoke throughout pregnancy had an average adjusted reduction in birth weight of 189 g (5.9%), compared with a 55 g (1.7%) reduction for neonates born to women who stopped smoking after the first trimester. For women who continued to smoke throughout pregnancy, an increased number of cigarettes smoked was associated with increased reductions in birth weight and neonatal chest and abdominal circumferences. For women who stopped smoking after the first trimester, stopping was a better predictor of neonatal anthropometric measurements than the number of cigarettes smoked early in pregnancy.
Conclusions: Except for the ponderal index, all neonatal anthropometric measurements studied showed some negative effect of maternal cigarette smoking. Head circumference is the measurement least reduced. Smoking cessation is a better predictor of infant size than the number of cigarettes smoked in the first trimester.

AB Arbitrary primed polymerase chain reactions (AP-PCR) were used to amplify different polymorphic genomic DNA fragments from various Old World Leishmania species. Using four 10-mer AP primers, geographic isolates of L. donovani and various Old World species of Leishmania could be readily distinguished from one another by the pattern of amplified DNA products. Our studies confirmed two important characteristics of AP-PCR: its abilities to amplify a consistent pattern of DNA fragments from the genomes of different isolates of a single species and to identify genetic polymorphisms between the species isolates. We selected three polymerphic DNA fragments that differentiate L. donovani geographic isolates for further analysis. Sequence analysis of the clones derived from these three polymorphic fragments revealed eight unique sequences. Six of eight unique clones hybridized to distinct RNAs upon Northern-blot analysis. Three of these six clones hybridized to RNAs expressed differentially in in vitro grown L. donovani pro- and ''amastigotes.'' One of the differentially expressed clones, LdE-6-1, exhibited restriction length polymorphisms that distinguished L. donovani from L. tropica and L. major. Comparative Northern blotting revealed that LdE-6-1 was differentially expressed in some members of the L. donovani species complex but not in L. major or L. tropica. These results demonstrate that AP-PCR can be used to generate products reflecting particular genes in organisms with low-complexity genomes.

AB Plasmodium spp maintain several structurally distinct sets of ribosomal RNA genes whose expression is developmentally regulated. This feature sets them apart from all other eukaryotes studied to date. In this review, Thomas McCutchan, Jun Li, Glenn McConkey, John Rogers and Andy Waters give an account of the progress in our understanding of this unusual phenomenon as it relates to the biology of the parasite. They also outline an interesting turnabout in scientific direction involving the use of the parasite as an important new model for the study of the eukaryotic ribosome.

AB Tobacco use is a major public health issue that has its onset primarily during the pediatric years. Preventing the onset of tobacco use by children and adolescents should be a priority. A comprehensive strategy includes interventions by pediatricians and other health professionals, policy changes, advertising restrictions, comprehensive school health education programs, and community advocacy. Because the physician-parent-chiId relationship is unique, physicians have many opportunities to help prevent tobacco use, both in their offices and in their communities.

AB Previous studies suggest that serum levels of the mucin-associated sialyl Lewis(a) (Le(a)) antigen (NeuAC alpha 2-3 Gal beta 1-3 [Fuc alpha 1-4]GlcNAc beta 1...) correlate with the pulmonary status of cystic fibrosis (CF) patients who have Le(a) or Lewis(b) blood types and can form the antigen. However, there is little information on serum sialyl Le(a) antigen levels in CF patients or normal children younger than 9 y. We measured serum antigen levels using the MAb 19-9 in normal term neonates, CF infants and young children, and infants and children who had bronchopulmonary dysplasia or asthma. The mean serum sialyl Le(a) antigen level of the CF patients was 46.7 U/mL, significantly above (p < 0.01) the mean levels of the three other groups. The mean serum sialyl Le(a) levels of the three non-CF groups were not significantly different from one another or from published normal values. We conclude that serum sialyl Le(a) antigen levels are elevated early in CF, but are normal in asthma and bronchopulmonary dysplasia patients.

AB Objective. To determine the effect of prenatal cocaine exposure on 3-month infant information processing and developmental assessments.
Methods. One hundred and eight infants, 61 cocaine-exposed and 47 controls, participated at 3 months of age in an infant-control habituation and novelty responsiveness procedure and in a developmental assessment using the Bayley Scales of Infant Development both administered by experimenters blind to the drug exposure status of the infant.
Results. Compared to the non-drug-exposed group, infants exposed prenatally to cocaine were significantly more likely to fail to start the habituation procedure and, for those who did, significantly more likely to react with irritability early in the procedure. The majority of infants in both groups reached the habituation criterion, and among those who did there were no significant differences between cocaine and non-cocaine-exposed infants in habituation or in recovery to a novel stimulus. Infants who were cocaine-exposed showed comparatively depressed performance on the motor (Psychomotor Developmental Index) but not the mental (Mental Developmental Index (MDI)) scales of the Bayley. These results obtained for habituation and Bayley MDI controlling for both perinatal and sociodemographic factors.
Conclusions. Differences in reactivity to novelty but not in information processing between cocaine-exposed and non-cocaine-exposed infants suggest that the effects of prenatal cocaine exposure may be on arousal and attention regulation rather than early cognitive processes.

AB Objectives. We sought to determine factors that would predict the development of subglottic stenosis (SGS) and tracheomalacia (TM) in preterm infants. The utility of a semiquantitative measurement of airway dimensions was assessed in relation to signs of airway complications. We also sought to determine from a high-risk population of infants those likely to have abnormal findings identified by bronchoscopic examination.
Methods. Prospective airway endoscopy was performed for preterm infants who were intubated for 7 days or more or who demonstrated chronic oxygen needs beyond 28 days after birth and 36 weeks postconceptional age. Subjects were 117 preterm (less than 36 weeks' gestation) infants from two level III intensive care nurseries. Endoscopy was used to classify the type and degree of airway injury. Subglottic stenosis was defined subjectively and compared with an objective measurement using subglottic spatial relations described as a trans-subglottic/vocal cord ratio (TSG/VC). Clinical signs and symptoms and other risk factors were evaluated as significant predictors of SGS and TM, identified by bronchoscopy.
Results. Moderate or severe airway abnormalities were identified in 32 patients (27.3%); 13 with SGS, 17 with TM, and 2 with both. All but one infant with TSG/VC less than 0.83 had signs and symptoms of airway dysfunction. Variables more commonly found in patients with SGS included greater number of intubations, use of inappropriately large endotracheal tubes, and longer duration of intubation. Higher averaged mean airway pressure during the first week after birth and lower gestational age were clinical features associated with TM.
Conclusions. Flexible bronchoscopic evaluation of a high-risk population demonstrated a higher incidence of moderate or severe SGS or TM than previously sub suspected, Subglottic stenosis and TM appear to have different etiologies based on different factors associated with their development. The TSG/VC ratio correlated well with obstructive symptoms and may represent a means to quantitate clinically subglottic narrowing. Infants with chronic lung disease who have persistently elevated partial pressure of carbon dioxide, apnea, or phonation abnormalities are most likely to have airway abnormalities identifiable by bronchoscopy.

AB 'Single' genes, necessary and sufficient to cause cancer, are contrasted with 'susceptibility' genes that are neither, but may act in the presence of specific environmental exposures to alter the chances of cancer in the host. The former are rare, are of high absolute and relative risks, have minimal dependence on exposures and therefore have low population attributable risks. A small number of such genes are well established in the literature and typically exhibit familial aggregations of disease that serve as a starting point for genetic studies.
'Susceptibility' genes, as typified by the pharmacogenetic model, are common, have low relative and absolute risk, are strongly dependent upon exposure, and may have potentially high population attributable risks. Methanistic and epidemiologic data are suggestive but currently fall short of confirmation for these associations. Familial aggregation is not a prominent feature and epidemiological study designs with careful exposure assessment is the investigative method of choice.
Both approaches require interdisciplinary expertise and benefit from advances in molecular biology.

AB We examined the oxidative metabolism of a beta-blocker bunitrolol (ETL) by 10 human cytochromes P450 (CYP) (1A2, 2A6, 2B6, 2C8, 2C9, 2D6, 2E1, 3A3, 3A4 or 3A5), which were individually expressed in Hep G2 cells with a vaccinia virus complementary DNA expression system, Among the 10 isozymes, only CYP2D6 and 1A2 at a substrate concentration of 5 mu m, and CYP2C8 and 2C9 in addition to the two isozymes at a BTL concentration of 1 mM, exhibited detectable BTL 4-hydroxylase activities, The activities at 1 mM ETL were on the order of CYP2D6 (100% as relative activity) > CYP1A2 (86%) >> CYP2C8 and 2C9 (7-8%). Enzyme kinetic parameters of CYP2D6 were calculated to be 4.41 mu m as a K-m value and 0.442 nmol min(-1) per nmol CYP as a V-max value, Kinetic parameters of CYP1A2 were calculated as 295 mu m and 0.411 nmol min(-1) per nmol CYP for K-m and V-m values, respectively. These results suggest that both CYP2D6 and 1A2 primarily catalyse BTL 4-hydroxylation, but that the former is a predominant isozyme responsible for the reaction at a low substrate concentration range of BTL in human liver.

AB Galanin is a 29 amino acid neuropeptide that coexists with norepinephrine in approximately 80% of locus coeruleus (LC) neurons in the rat. The effects of chronic, naturalistic stress on preprogalanin mRNA in the LC was studied. The visible burrow system (VBS) served as the stress paradigm. Long-Evans rats (three males and two females) were housed together in the VBS for 13 days. The males established dominance hierarchies during this period. On day 14, preprogalanin mRNA in the LC was significantly elevated in subordinate rats compared to dominant and control rats, as measured by quantitative in situ hybridization. Levels of mRNA were positively correlated with the number of wounds by day 7 and day 14 and negatively correlated with body weight gain by day 14. These results suggest that the neuropeptide galanin may be overexpressed during chronic stress in rats.

AB In monogamous mammals, males typically show selective affiliation with a single mate, high levels of paternal care, and aggression towards conspecifics to protect mate and offspring. We have previously described how selective aggression and affiliation increase after mating in the male prairie vole, Microtus ochrogaster. The current studies further explored the behavioral changes that follow mating in the male of this species. The first set of experiments tested males on several behavioral measures after 24 h of either mating, social (but not sexual) exposure, or no social contact. After 24 h of mating, but not after the other two conditions, aggression and affiliation (partner preference) increased as previously reported. In addition, mated animals showed increased exploration of the open arms of a plus maze, consistent with decreased fearfulness. There were no group differences in paternal behavior (which was high in all three conditions) or analgesia (assessed by tail flick latency). To determine the minimum amount of mating necessary for the induction of aggression, males were tested in a resident-intruder paradigm after 1,6, or 24 h of mating. Although 1 h of mating was associated with a transient increase in the frequency of threats and attacks, the full spectrum of enduring aggression was observed only in the males given 24 h of mating. In a final experiment, the behavioral consequences of mating were studied in males of the closely related montane vole (Microtus montanus) which does not pair bond. Males of this nonmonogamous vole species did not show increased aggression, partner preference, or alterations in plus maze exploration following 24 h of mating. These results demonstrate the importance of prolonged mating for the induction of pair bonding in the monogamous male and they suggest that increases in aggression and affiliation are associated with decreased fearfulness in pair bonded males.

AB The expression of various melanogenic proteins, including tyrosinase, the tyrosinase-related proteins 1 (TRP1) and 2 (TRP2/DOPAchrome tautomerase), and the silver protein in human melanocytes was studied in six different human melanoma cell lines and compared to a mouse derived melanoma cell line. Analysis of the expression of tyrosinase, TRP1, TRP2, and the silver protein using flow cytometry revealed that in general there was a positive correlation between melanin formation and the expression of those melanogenic enzymes. Although several of the melanoma cell lines possessed significant activities of TRP2, the levels of DOPAchrome tautomerase in extracts of human cells were relatively low compared to those in murine melanocytes. Melanins derived from melanotic murine JB/MS cells, from melanotic human Ihara cells and HM-IY cells, from sepia melanin, and from C57BL/6 mouse hair were chemically analyzed. JB/MS cells, as well as Ihara cells and HM-TY cells, possessed significant amounts of 5,6-dihydroxyindole-2-carboxylic acid (DHICA) derived melanins, this being dependent on the activity of TRP2. Kinetic HPLC assays showed that 5,6-dihydroxyindole (DHI) produced during melanogenesis was metabolized quickly to melanin in pigmented KHm-1/4 cells, whereas DHI was stable in amelanotic human SK-MEL-24 cells. A melanogenic inhibitor that has been purified from SK-MEL-24 cells that suppressed oxidation of DHI in the presence or absence of tyrosinase, but had no effect on DHICA oxidation. The sum of these results suggest that the expression of melanogenic enzymes as well as the activity of a melanogenic inhibitor are critical to the production of melanin synthesis in humans.

AB We expressed a gene for YY1, the multifunctional mammalian transcription factor, with a recombinant baculovirus in insect cells and obtained high levels of protein in cell. lysates. A simple and efficient purification method was developed. In the final step, we used DNA affinity chromatography with concatermerized sequence derived from the upstream region of the B19 parvovirus P6 promoter, which has strong affinity for YY1, Approximately 1.8 mg of highly purified YY1 was obtained from 10(9) Sf9 cells. Highly purified YY1 behaved as authentic YY1 on electrophoretic mobility shift assays and in enhancing transcription from the P6 promoter. YY1 produced in a baculovirus system should prove useful for in vitro transcription assays of YY1 and related regulatory proteins. (C) 1995 Academic Press, Inc.

We present here the results of experiments in which the ptsH gene was cloned into a vector for high level expression in Escherichia coli of the phosphocarrier protein, Conditions were developed for overproduction and purification of HPr by a two-column procedure. The purified protein, analyzed by Edman degradation and mass spectrometry, was found to have been processed by removal of the N-terminal methionine residue. Examination of the purified protein by gel electrophoresis under isoelectric focusing conditions revealed that it has an unusually high isoelectric point. (C) Academic Press, Inc.

AB Rhizopuspepsin and other fungal aspartic proteinases are distinct from the mammalian enzymes in that they are able to cleave substrates with lysine in the P-1, position. Sequence and structural comparisons suggest that two aspartic acid residues, Asp 30 and Asp 77 (pig pepsin numbering), may be responsible for generating this unique specificity. Asp 30 and Asp 77 were changed to the corresponding residues in porcine pepsin, Ile 30 and Thr 77, to create single and double mutants. The zymogen forms of the wild-type and mutant enzymes were overexpressed in Escherichia coli as inclusion bodies. Following solubilization, denaturation, refolding, activation, and purification to homogeneity, structural and kinetic comparisons were made. The mutant enzymes exhibited a high degree of structural similarity to the wild-type recombinant protein and a native isozyme. The catalytic activities of the recombinant proteins were analyzed with chromogenic substrates containing lysine in the P-1, P-2, or P-3 positions. Mutation of Asp 77 resulted in a loss of 7 kcal mol(-1) of transition-state stabilization energy in the hydrolysis of the substrate containing lysine in P-1. An inhibitor containing the positively charged P-1-lysine side chain inhibited only the enzymes containing Asp 77. Inhibition of the Asp 77 mutants of rhizopuspepsin and several mammalian enzymes was restored upon acetylation of the lysine side chain. These results suggest that an exploitation of the specific electrostatic interaction of Asp 77 in the active site of fungal enzymes may lead to the design of compounds that preferentially inhibit a variety of related Candida proteinases in immunocompromised patients.
