    Lipoprotein mutations in pigs are associated with elevated plasma cholesterol and atherosclerosis (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-12-19
    Description: A strain of pigs bearing three immunogenetically defined lipoprotein-associated markers (allotypes), designated Lpb5, Lpr1, and Lpu1, has marked hypercholesterolemia on a low fat, cholesterol-free diet. Unlike individuals with familial hypercholesterolemia or WHHL rabbits, the affected pigs have normal low density lipoprotein receptor activity. The animals, by 7 months of age, have extensive atherosclerotic lesions in all three coronary arteries. This strain of pig represents an animal model for atherosclerosis and hypercholesterolemia associated with mutations affecting the structures of plasma lipoproteins. One of the variant apolipoproteins, Lpb5, is apolipoprotein-B. A second variant apolipoprotein (Lpr1), termed apo-R, is a 23-kilodalton protein present in both the very low density (d less than 1.006 g/ml) and the very high density (d greater than 1.21 g/ml) fractions of pig plasma. Isoforms of this protein correlate with two Lpr alleles, Lpr1 and Lpr2. The Lpr genes segregate independently of the Lpb5 and Lpu1 alleles. The Lpu1 allotype is a component of low density lipoprotein and is genetically linked to Lpb5.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rapacz, J -- Hasler-Rapacz, J -- Taylor, K M -- Checovich, W J -- Attie, A D -- AG05-856/AG/NIA NIH HHS/ -- HL30594/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 19;234(4783):1573-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3787263" target="_blank"〉PubMed〈/a〉

    Human multidrug-resistant cell lines: increased mdr1 expression can precede gene amplification (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-02
    Description: The development of simultaneous resistance to multiple structurally unrelated drugs is a major impediment to cancer chemotherapy. Multidrug resistance in human KB carcinoma cells selected in colchicine, vinblastine, or Adriamycin is associated with amplification of specific DNA sequences (the multidrug resistance locus, mdr1). During colchicine selection resistance is initially accompanied by elevated expression of a 4.5-kilobase mdr1 messenger RNA (mRNA) without amplification of the corresponding genomic sequences. During selection for increased levels of resistance, expression of this mRNA is increased simultaneously with amplification of mdr1 DNA. Increased expression and amplification of mdr1 sequences were also found in multidrug-resistant sublines of human leukemia and ovarian carcinoma cells. These results suggest that increased expression of mdr1 mRNA is a common mechanism for multidrug resistance in human cells. Activation of the mdr1 gene by mutations or epigenetic changes may precede its amplification during the development of resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, D W -- Fojo, A -- Chin, J E -- Roninson, I B -- Richert, N -- Pastan, I -- Gottesman, M M -- New York, N.Y. -- Science. 1986 May 2;232(4750):643-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3457471" target="_blank"〉PubMed〈/a〉

    Tandem duplication of D-loop and ribosomal RNA sequences in lizard mitochondrial DNA (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-09-26
    Description: Some Cnemidophorus exsanguis have mitochondrial DNA's (mtDNA's) that are 22.2 kilobases (kb) in size, whereas most have mtDNA's of 17.4 kb. Restriction site mapping, DNA transfer hybridization experiments, and electron microscopy show that the size increment stems from the tandem duplication of a 4.8-kb region that includes regulatory sequences and transfer and ribosomal RNA genes. This observation is notable in that sequences outside of the control region are involved in major length variation. Besides revealing a novel form of mtDNA evolution in animals, these duplications provide a useful system for investigating the molecular and evolutionary biology of animal mtDNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moritz, C -- Brown, W M -- GM30144/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Sep 26;233(4771):1425-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3018925" target="_blank"〉PubMed〈/a〉

    Immortalization of human T lymphocytes after transfection of Epstein-Barr virus DNA (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-29
    Description: Epstein-Barr virus (EBV), a ubiquitous human herpesvirus, has the ability to transform human B lymphocytes. No other cell type has been experimentally transformed by EBV, either by intact virions or naked viral DNA and subgenomic fragments. Two immortalized human T-lymphoblastoid cell lines have now been established by transfecting cord blood lymphocytes with purified B95-8 viral DNA enclosed in fusogenic Sendai virus envelopes (RSVE) and then exposing the cells to EBV from a P3HR-1 cell subclone. One of these lines, which has been fully characterized, is termed HBD-1. This line is positive for EBV DNA and expresses surface OKT11, OKT4, and Tac receptors, but not M-1, mu immunoglobulin chains, EBV receptors, or B-1 surface markers. The cells contain fully rearranged T-cell receptor genes and germline immunoglobulin genes. The karyotype of the cells is normal, they do not require interleukin-2 for growth, and do not contain human T-lymphotropic virus type I. However, the HBD-1 cells contain incomplete EBV genomes and express several EBV-determined antigens, including the early antigen type D, membrane antigens, but not EBV-determined nuclear antigen (EBNA). This association of the EBV genome with permanently growing hematopoietic cells of non B-cell lineage should prove useful in studies on the mechanism of EBV-mediated cell transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevenson, M -- Volsky, B -- Hedenskog, M -- Volsky, D J -- CA33386/CA/NCI NIH HHS/ -- CA37465/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Aug 29;233(4767):980-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3016899" target="_blank"〉PubMed〈/a〉

    Suprachiasmatic nucleus vasopressin messenger RNA: circadian variation in normal and Brattleboro rats (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-04-18
    Description: In situ hybridization of an oligonucleotide probe complementary to vasopressin messenger RNA (mRNA) in sections from normal or Brattleboro rat hypothalami revealed hybridization densities in each of three vasopressin-rich nuclei: the supraoptic, paraventricular, and suprachiasmatic. When entrained to a daily light-dark cycle, each rat strain displayed diurnal variation in hybridizable mRNA in the suprachiasmatic, but not in the supraoptic or paraventricular nuclei. The higher values for suprachiasmatic mRNA in the morning correlate well with previously elucidated morning increases in vasopressin immunoreactivity in the cerebrospinal fluid. These results support the utility of in situ hybridization techniques for elucidating physiological influences on regional peptidergic function, are consistent with a prominent role for vasopressinergic suprachiasmatic neurons in generating the cerebrospinal fluid vasopressin rhythm, and suggest that regulation of this mRNA rhythm is not dependent on release of intact peptide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Uhl, G R -- Reppert, S M -- New York, N.Y. -- Science. 1986 Apr 18;232(4748):390-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3961487" target="_blank"〉PubMed〈/a〉

    Calcium antagonist receptors in cardiomyopathic hamster: selective increases in heart, muscle, brain (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-04-25
    Description: The Syrian cardiomyopathic hamster has a hereditary disease in which a progressive myocardial necrosis mimics human forms of cardiac hypertrophy. Lesions are associated with calcium overload and can be prevented with the calcium antagonist verapamil. Numbers of receptor binding sites for calcium antagonists in heart, brain, skeletal muscle, and smooth muscle were markedly increased in cardiomyopathic hamsters. The uptake of calcium-45 into brain synaptosomes was also increased in cardiomyopathic hamsters. The increase in calcium antagonist receptors and related voltage-sensitive calcium channels may be involved in the pathogenesis of this cardiomyopathy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wagner, J A -- Reynolds, I J -- Weisman, H F -- Dudeck, P -- Weisfeldt, M L -- Snyder, S H -- HL-17655/HL/NHLBI NIH HHS/ -- MH-18501/MH/NIMH NIH HHS/ -- NS-16375/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Apr 25;232(4749):515-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3008330" target="_blank"〉PubMed〈/a〉

    Expression and characterization of the trans-activator of HTLV-III/LAV virus (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-11-21
    Description: The human T-lymphotropic retrovirus HTLV-III/LAV encodes a trans-activator that increases viral gene expression. We expressed this trans-activator in animal cells and studied its structural and functional characteristics. The putative trans-activator protein was immunoprecipitated from overproducing stable cell lines and shown to migrate as a 14-kilodalton polypeptide on sodium dodecyl sulfate-polyacrylamide gels. S1 nuclease mapping experiments showed that the trans-activator increases the levels of steady-state messenger RNA transcribed from the viral long terminal repeat promoter. Sequences within the R region of the HTLV-III/LAV long terminal repeat are essential for trans-activation. Quantitations of messenger RNA and protein showed that the protein increase was greater than the messenger RNA increase in CV1 and HeLa cells, indicating that more than one mechanism was responsible for the trans-activation and that cell type-specific factors may determine the final level of trans-activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wright, C M -- Felber, B K -- Paskalis, H -- Pavlakis, G N -- N01-CO-23909/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Nov 21;234(4779):988-92.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3490693" target="_blank"〉PubMed〈/a〉

    Chromosome Y-specific DNA is transferred to the short arm of X chromosome in human XX males (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-15
    Description: Y-chromosomal DNA is present in the genomes of most human XX males. In these cases, maleness is probably due to the presence of the Y-encoded testis-determining factor (TDF). By means of in situ hybridization of a probe (pDP105) detecting Y-specific DNA to metaphases from three XX males, it was demonstrated that the Y DNA is located on the tip of the short arm of an X chromosome. This finding supports the hypothesis that XX maleness is frequently the result of transfer of Y DNA, including TDF, to a paternally derived X chromosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersson, M -- Page, D C -- de la Chapelle, A -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):786-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3738510" target="_blank"〉PubMed〈/a〉

    Aminoguanidine prevents diabetes-induced arterial wall protein cross-linking (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-06-27
    Description: Age-associated increases in collagen cross-linking and accumulation of advanced glycosylation products are both accelerated by diabetes, suggesting that glucose-derived cross-link formation may contribute to the development of chronic diabetic complications as well as certain physical changes of aging. Aminoguanidine, a nucleophilic hydrazine compound, prevented both the formation of fluorescent advanced nonenzymatic glycosylation products and the formation of glucose-derived collagen cross-links in vitro. Aminoguanidine administration to rats was equally effective in preventing diabetes-induced formation of fluorescent advanced nonenzymatic glycosylation products and cross-linking of arterial wall connective tissue protein in vivo. The identification of aminoguanidine as an inhibitor of advanced nonenzymatic glycosylation product formation now makes possible precise experimental definition of the pathogenetic significance of this process and suggests a potential clinical role for aminoguanidine in the future treatment of chronic diabetic complications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brownlee, M -- Vlassara, H -- Kooney, A -- Ulrich, P -- Cerami, A -- AM 19655/AM/NIADDK NIH HHS/ -- R01-AM 33861/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1986 Jun 27;232(4758):1629-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3487117" target="_blank"〉PubMed〈/a〉

    Atrial natriuretic peptide elevation in congestive heart failure in the human (1986)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1986-03-07
    Description: A sensitive radioimmunoassay for atrial natriuretic peptide was used to examine the relation between circulating atrial natriuretic peptide and cardiac filling pressure in normal human subjects, in patients with cardiovascular disease and normal cardiac filling pressure, and in patients with cardiovascular disease and elevated cardiac filling pressure with and without congestive heart failure. The present studies establish a normal range for atrial natriuretic peptide in normal human subjects. These studies also establish that elevated cardiac filling pressure is associated with increased circulating concentrations of atrial natriuretic peptide and that congestive heart failure is not characterized by a deficiency in atrial natriuretic peptide, but with its elevation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burnett, J C Jr -- Kao, P C -- Hu, D C -- Heser, D W -- Heublein, D -- Granger, J P -- Opgenorth, T J -- Reeder, G S -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1145-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2935937" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1986-05-16
    Description: Hepatitis delta virus (HDV) is a replication-defective etiological agent of hepatitis that requires hepatitis B virus (HBV) as a helper. A complementary DNA (cDNA) fragment of the RNA genome of HDV was cloned into the plasmid vector pBR322, and the primary nucleotide sequence and predicted protein products of the cDNA fragment were determined. This cloned cDNA fragment has been used as a sensitive radioactive probe for the detection of HDV RNA in the serum of patients with either acute or chronic HDV infections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Denniston, K J -- Hoyer, B H -- Smedile, A -- Wells, F V -- Nelson, J -- Gerin, J L -- N01-AI-22665/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1986 May 16;232(4752):873-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3704630" target="_blank"〉PubMed〈/a〉

    Interferon and c-ets-1 genes in the translocation (9;11)(p22;q23) in human acute monocytic leukemia (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-17
    Description: Gene probes for interferons alpha and beta 1 and v-ets were hybridized to metaphase chromosomes from three patients with acute monocytic leukemia who had a chromosomal translocation, t(9;11)(p22;q23). The break in the short arm of chromosome 9 split the interferon genes, and the interferon-beta 1 gene was translocated to chromosome 11. The c-ets-1 gene was translocated from chromosome 11 to the short arm of chromosome 9 adjacent to the interferon genes. No DNA rearrangement was observed when these probes were hybridized to genomic DNA from leukemic cells of two of the patients. The results suggest that the juxtaposition of the interferon and c-ets-1 genes may be involved in the pathogenesis of human monocytic leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diaz, M O -- Le Beau, M M -- Pitha, P -- Rowley, J D -- CA 16910/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 17;231(4735):265-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3455787" target="_blank"〉PubMed〈/a〉

    Age-dependent changes in proteins of Drosophila melanogaster (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-03-07
    Description: Several molecular theories of aging postulate that there are age-dependent changes in gene expression and that these changes contribute to the reduction in the viability of senescent cells. High-resolution, semiautomated, quantitative two-dimensional gel electrophoresis of many soluble proteins was used to test this hypothesis in Drosophila. Two-dimensional protein gel patterns were analyzed for each of three age groups of [(35)S]methionine-labeled adult male Drosophila melanogaster, which, except for their spermatocytes, consist entirely of fixed postmitotic cells. Seven relatively abundant polypeptides expressed in middle-aged (28-day-old) flies were absent in both young(10-day-old) and old (44-day-old) flies. Quantitative analyses of an additional 100 polypeptides were carried out by computer-assisted microdensitometry of fluorograms of the gel preparations. These analyses revealed a significant age-related heterogeneity in the quantitative distribution of radiolabel in these proteins. The data indicate that the qualitative pattern of gene expression is identical in young and old flies, but that profound quantitative changes occur in the expression of proteins during the Drosophila life-span.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fleming, J E -- Quattrocki, E -- Latter, G -- Miquel, J -- Marcuson, R -- Zuckerkandl, E -- Bensch, K G -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1157-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3080809" target="_blank"〉PubMed〈/a〉

    Circulating atrial natriuretic peptides in conscious rats: regulation of release by multiple factors (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-02
    Description: Cardiocytes in the atria contain a prohormone that gives rise to atrial natriuretic peptides (ANP's), which have intrinsic hemodynamic regulatory activity. The distribution of ANP's in the brain suggests the involvement of these peptides in central cardiovascular regulation. In conscious rats with chronic indwelling catheters, volume loading with isotonic saline or glucose increased the amount of circulating immunoreactive ANP's by a factor of 4 to 5, as determined by radioimmunoassay. Hyperosmotic challenge with a hypertonic NaCl solution or anesthesia with halothane caused similar increases in plasma ANP's. Results obtained with the denervated-heart preparation indicate that neuronal influences are important in the release of ANP's induced by volume loading. As judged from reversed-phase high-performance liquid chromatography of extracted plasma and radioimmunoassay of collected fractions, the circulating physiologically important ANP's in the conscious rodent appear to be alpha-rANP(5-28) (atriopeptin III) and either alpha-rANP(3-28) [ANF(8-33)] or alpha-rANP(1-28) (ANF).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eskay, R -- Zukowska-Grojec, Z -- Haass, M -- Dave, J R -- Zamir, N -- New York, N.Y. -- Science. 1986 May 2;232(4750):636-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2938258" target="_blank"〉PubMed〈/a〉

    Deregulation of c-myc by translocation of the alpha-locus of the T-cell receptor in T-cell leukemias (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-16
    Description: Two human T-cell leukemias carrying a t(8;14)(q24;q11) chromosome translocation were studied for rearrangements and expression of the c-myc oncogene. For one leukemia, rearrangement was detected in a region immediately distal (3') to the c-myc locus; no rearrangements of c-myc were observed in the second case (DeF). However, studies with hybrids between human and mouse leukemic T cells indicated that in the leukemic cells of DeF, the breakpoint in chromosome 14 occurred between genes for the variable (V alpha) and the constant (C alpha) regions for the alpha chain of the T-cell receptor. The C alpha locus had translocated to a region more than 38 kilobases 3' to the involved c-myc oncogene. Since human c-myc transcripts were expressed only in hybrids carrying the 8q+ chromosome but not in hybrids containing the normal chromosome 8, it is concluded that the translocation of the C alpha locus 3' to the c-myc oncogene can result in its transcriptional deregulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Erikson, J -- Finger, L -- Sun, L -- ar-Rushdi, A -- Nishikura, K -- Minowada, J -- Finan, J -- Emanuel, B S -- Nowell, P C -- Croce, C M -- CA10815/CA/NCI NIH HHS/ -- CA25875/CA/NCI NIH HHS/ -- CA39860/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 May 16;232(4752):884-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3486470" target="_blank"〉PubMed〈/a〉

    Cross-regulatory interactions among pair-rule genes in Drosophila (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-29
    Description: The pair-rule genes of Drosophila are required for the subdivision of the developing embryo into a repeating series of homologous body segments. One of the pair-rule genes, even-skipped (eve), appears to be particularly important for the overall segmentation pattern since eve- embryos lack all segmental subdivisions in the middle body region. On the basis of homeo box cross-homology we have isolated a gene, S72, which probably corresponds to eve. In embryo tissue sections S72 transcripts show a periodic distribution pattern. The eve- phenotype appears to involve altered patterns of fushi tarazu and engrailed expression. These and other findings suggest that pair-rule gene expression might involve hierarchical cross-regulatory interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harding, K -- Rushlow, C -- Doyle, H J -- Hoey, T -- Levine, M -- New York, N.Y. -- Science. 1986 Aug 29;233(4767):953-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3755551" target="_blank"〉PubMed〈/a〉

    The neuroendocrine thymus: coexistence of oxytocin and neurophysin in the human thymus (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-04-25
    Description: Immunoreactive oxytocin and neurophysin were identified and measured by radioimmunoassay in human thymus extracts. Serial dilutions of extracts paralleled the appropriate standard curves. Thymus-extracted oxytocin and neurophysin eluted in the same positions as reference preparations on Sephadex G-75. Authenticity of oxytocin was confirmed by biological assay and high-performance liquid chromatography analysis. In most instances, thymus contents of oxytocin and neurophysin were far greater than those expected from known circulating concentrations and declined with increasing age. The molar ratio of oxytocin to neurophysin in thymus was similar to that found in the hypothalamo-neurohypophyseal system, which strongly suggested with the other data a local synthesis of oxytocin. These findings indicate the presence of neurohypophyseal peptides in the human thymus and further support the concept of a neuroendocrine function integrated in an immune structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geenen, V -- Legros, J J -- Franchimont, P -- Baudrihaye, M -- Defresne, M P -- Boniver, J -- New York, N.Y. -- Science. 1986 Apr 25;232(4749):508-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3961493" target="_blank"〉PubMed〈/a〉

    Cloning of a cDNA for a T cell-specific serine protease from a cytotoxic T lymphocyte (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-16
    Description: A new serine protease was encoded by a clone isolated from a murine cytotoxic T-lymphocyte complementary DNA library by an RNA-hybridization competition protocol. Complementary transcripts were detected in cytotoxic T lymphocytes, spleen cells from nude mice, a rat natural killer cell leukemia, and in two of eight T-helper clones (both cytotoxic), but not in normal mouse kidney, liver, spleen, or thymus, nor in several tested T- and B-cell tumors. T-cell activation with concanavalin A plus interleukin-2 induced spleen cells to express this gene with kinetics correlating with the acquisition of cytolytic capacity. The nucleotide sequence of this gene encoded an amino acid sequence of approximately 25,700 daltons, with 25 to 35 percent identity to members of the serine protease family. The active site "charge-relay" residues (His57, Asp102, and Ser195 of the chymotrypsin numbering system) are conserved, as well as the trypsin-specific Asp (position 189 in trypsin). A Southern blot analysis indicated that this gene is conserved in humans, mouse, and chicken. This serine protease may have a role in lymphocyte lysis and a "lytic cascade."〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gershenfeld, H K -- Weissman, I L -- AI 19512/AI/NIAID NIH HHS/ -- CA09032/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 May 16;232(4752):854-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2422755" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-31
    Description: Acetaldehyde, the end product of oxidative ethanol metabolism, contributes to alcohol-induced disease in the liver, but cannot account for damage in organs such as the pancreas, heart, or brain, where oxidative metabolism is minimal or absent; nor can it account for the varied patterns of organ damage found in chronic alcoholics. Thus other biochemical mediators may be important in the pathogenesis of alcohol-induced organ damage. Many human organs were found to metabolize ethanol through a recently described nonoxidative pathway to form fatty acid ethyl esters. Organs lacking oxidative alcohol metabolism yet frequently damaged by ethanol abuse have high fatty acid ethyl ester synthetic activities and show substantial transient accumulations of fatty acid ethyl esters. Thus nonoxidative ethanol metabolism in addition to the oxidative pathway may be important in the pathophysiology of ethanol-induced disease in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Laposata, E A -- Lange, L G -- HL-30152/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 31;231(4737):497-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3941913" target="_blank"〉PubMed〈/a〉

    All members of the MHC multigene family respond to thyroid hormone in a highly tissue-specific manner (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-07
    Description: In mammals different isoforms of myosin heavy chain are encoded by the members of a multigene family. The expression of each gene of this family is regulated in a tissue- and developmental stage-specific manner as well as by hormonal and various pathological stimuli. In this study the molecular basis of isoform switches induced in myosin heavy chain by thyroid hormone was investigated. The expression of the myosin heavy chain gene family was analyzed in seven different muscles of adult rats subjected to hypo- or hyperthyroidism with complementary DNA probes specific for six different myosin heavy chain genes. The results demonstrate that all six genes are responsive to thyroid hormone. More interestingly, the same myosin heavy chain gene can be regulated by thyroid hormone in highly different modes, even in opposite directions, depending on the tissue in which it is expressed. Furthermore, the skeletal embryonic and neonatal myosin heavy chain genes, so far considered specific to these two developmental stages, can be reinduced by hypothyroidism in specific adult muscles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Izumo, S -- Nadal-Ginard, B -- Mahdavi, V -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):597-600.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3945800" target="_blank"〉PubMed〈/a〉

    Systemic ethanol: selective enhancement of responses to acetylcholine and somatostatin in hippocampus (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-10
    Description: In rat hippocampal pyramidal cells tested in situ by iontophoresis of several neurotransmitters, ethanol significantly enhanced excitatory responses to acetylcholine and inhibitory responses to somatostatin-14 but had no statistically significant effect on excitatory responses to glutamate or inhibitory responses to gamma-aminobutyric acid or, in preliminary tests, to norepinephrine or serotonin. The effects of ethanol on responses to acetylcholine and somatostatin-14 may provide insight into synaptic mechanisms underlying the behavioral consequences of ethanol intoxication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mancillas, J R -- Siggins, G R -- Bloom, F E -- AA-06420/AA/NIAAA NIH HHS/ -- AM-26741/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 10;231(4734):161-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2867600" target="_blank"〉PubMed〈/a〉

    The hypogonadal mouse: reproductive functions restored by gene therapy (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-12-12
    Description: The hypogonadal (hpg) mouse lacks a complete gonadotropin-releasing hormone (GnRH) gene and consequently cannot reproduce. Introduction of an intact GnRH gene into the genome of these mutant mice resulted in complete reversal of the hypogonadal phenotype. Transgenic hpg/hpg homozygotes of both sexes were capable of mating and producing offspring. Pituitary and serum concentrations of luteinizing hormone, follicle-stimulating hormone, and prolactin were restored to those of normal animals. Immunocytochemistry and in situ hybridization showed that GnRH expression was restored in the appropriate hypothalamic neurons of the transgenic hpg animals, an indication of neural-specific expression of the introduced gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mason, A J -- Pitts, S L -- Nikolics, K -- Szonyi, E -- Wilcox, J N -- Seeburg, P H -- Stewart, T A -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1372-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3097822" target="_blank"〉PubMed〈/a〉

    Characterization of the supernumerary chromosome in cat eye syndrome (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-02
    Description: Most individuals with cat eye syndrome (CES) have a supernumerary bisatellited chromosome which, on the basis of cytogenetic evidence, has been reported to originate from either chromosome 13 or 22. To resolve this question, a single-copy DNA probe, D22S9, was isolated and localized to 22q11 by in situ hybridization to metaphase chromosomes. The number of copies of this sequence was determined in CES patients by means of Southern blots and densitometry analysis of autoradiographs. In patients with the supernumerary chromosome, four copies were found, whereas in one patient with a duplication of part of chromosome 22, there were three copies. Therefore, the syndrome results from the presence of either three or four copies of DNA sequences from 22q11; there is no evidence that sequences from other chromosomes are involved. This work demonstrates how DNA sequence dosage analysis can be used to study genetic disorders that are not readily amenable to standard cytogenetic analysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDermid, H E -- Duncan, A M -- Brasch, K R -- Holden, J J -- Magenis, E -- Sheehy, R -- Burn, J -- Kardon, N -- Noel, B -- Schinzel, A -- CA06927/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 May 2;232(4750):646-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3961499" target="_blank"〉PubMed〈/a〉

    Age and infertility (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-09-26
    Description: Direct evidence on age patterns of infecundity and sterility cannot be obtained from contemporary populations because such large fractions of couples use contraception or have been sterilized. Instead, historical data are exploited to yield upper bounds applicable to contemporary populations on the proportions sterile at each age. Examination of recent changes in sexual behavior that may increase infecundity indicates that sexually transmitted infections, the prime candidate for hypothesized rises in infertility, are unlikely to have added to infecundity to any great extent. These results imply that a woman in a monogamous union faces only moderate increases in the probability of becoming sterile (or infecund) until her late thirties. Nevertheless, it appears that recent changes in reproductive behavior were guaranteed to result in the perception that infecundity is on the rise.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Menken, J -- Trussell, J -- Larsen, U -- HD11720/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1986 Sep 26;233(4771):1389-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3755843" target="_blank"〉PubMed〈/a〉

    Different mutations in Ashkenazi Jewish and non-Jewish French Canadians with Tay-Sachs disease (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-06-27
    Description: Tay-Sachs disease patients of Ashkenazi Jewish and non-Jewish French Canadian origin are affected with a clinically identical form of this inherited disease. Both have a similar gene frequency for the disorder, which is tenfold higher than that found in the general population. Unlike other patients with the disease, who often display variation at the clinical or biochemical level, the absence of such differences between these two groups has prompted the idea that they may harbor the same mutation. In this report, a complementary DNA clone coding for the alpha chain of human beta-hexosaminidase has been used to analyze the genetic lesions in the alpha-chain locus of two patients with Tay-Sachs disease from each of these groups. On the basis of DNA hybridization analyses, the alpha-chain gene of the Ashkenazi patients appears intact while the alpha-chain gene of French Canadian patients has a 5' deletion of approximately 5 to 8 kilobases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myerowitz, R -- Hogikyan, N D -- New York, N.Y. -- Science. 1986 Jun 27;232(4758):1646-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3754980" target="_blank"〉PubMed〈/a〉

    Mechanism of the rapid effect of 17 beta-estradiol on medial amygdala neurons (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-07-11
    Description: The mechanism by which sex steroids rapidly modulate the excitability of neurons was investigated by intracellular recording of neurons in rat medial amygdala brain slices. Brief hyperpolarization and increased potassium conductance were produced by 17 beta-estradiol. This effect persisted after elimination of synaptic input and after suppression of protein synthesis. Thus, 17 beta-estradiol directly changes the ionic conductance of the postsynaptic membrane of medial amygdala neurons. In addition, a greater proportion of the neurons from females than from males responded to 17 beta-estradiol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nabekura, J -- Oomura, Y -- Minami, T -- Mizuno, Y -- Fukuda, A -- New York, N.Y. -- Science. 1986 Jul 11;233(4760):226-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3726531" target="_blank"〉PubMed〈/a〉

    AIDS in Africa: an epidemiologic paradigm (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-11-21
    Description: Cases of the acquired immune deficiency syndrome (AIDS) have been reported in countries throughout the world. Initial surveillance studies in Central Africa suggest an annual incidence of AIDS of 550 to 1000 cases per million adults. The male to female ratio of cases is 1:1, with age- and sex-specific rates greater in females less than 30 years of age and greater in males over age 40. Clinically, AIDS in Africans is often characterized by a diarrhea-wasting syndrome, opportunistic infections, such as tuberculosis, cryptococcosis, and cryptosporidiosis, or disseminated Kaposi's sarcoma. From 1 to 18% of healthy blood donors and pregnant women and as many as 27 to 88% of female prostitutes have antibodies to human immunodeficiency virus (HIV). The present annual incidence of infection is approximately 0.75% among the general population of Central and East Africa. The disease is transmitted predominantly by heterosexual activity, parenteral exposure to blood transfusions and unsterilized needles, and perinatally from infected mothers to their newborns, and will continue to spread rapidly where economic and cultural factors favor these modes of transmission. Prevention and control of HIV infection through educational programs and blood bank screening should be an immediate public health priority for all African countries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Quinn, T C -- Mann, J M -- Curran, J W -- Piot, P -- New York, N.Y. -- Science. 1986 Nov 21;234(4779):955-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3022379" target="_blank"〉PubMed〈/a〉

    Hu-ets-1 and Hu-ets-2 genes are transposed in acute leukemias with (4;11) and (8;21) translocations (1986)

    Publication Date: 1986-01-24
    Description: Human probes identifying the cellular homologs of the v-ets gene, Hu-ets-1 and Hu-ets-2, and two panels of rodent-human cell hybrids were used to study specific translocations occurring in acute leukemias. The human ets-1 gene was found to translocate from chromosome 11 to 4 in the t(4;11)(q21;23), a translocation characteristic of a subtype of leukemia that represents the expansion of a myeloid/lymphoid precursor cell. Similarly, the human ets-2 gene was found to translocate from chromosome 21 to chromosome 8 in the t(8;21)(q22;q22), a nonrandom translocation commonly found in patients with acute myeloid leukemia with morphology M2 (AML-M2). Both translocations are associated with expression different from the expression in normal lymphoid cells of ets genes, raising the possibility that these genes play a role in the pathogenesis of these leukemias.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sacchi, N -- Watson, D K -- Guerts van Kessel, A H -- Hagemeijer, A -- Kersey, J -- Drabkin, H D -- Patterson, D -- Papas, T S -- AG00029/AG/NIA NIH HHS/ -- HD17449/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 24;231(4736):379-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3941901" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1986-04-11
    Description: Human color vision is based on three light-sensitive pigments. The isolation and sequencing of genomic and complementary DNA clones that encode the apoproteins of these three pigments are described. The deduced amino acid sequences show 41 +/- 1 percent identity with rhodopsin. The red and green pigments show 96 percent mutual identity but only 43 percent identity with the blue pigment. Green pigment genes vary in number among color-normal individuals and, together with a single red pigment gene, are proposed to reside in a head-to-tail tandem array within the X chromosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nathans, J -- Thomas, D -- Hogness, D S -- New York, N.Y. -- Science. 1986 Apr 11;232(4747):193-202.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2937147" target="_blank"〉PubMed〈/a〉

    Stress-induced inhibition of reproductive functions: role of endogenous corticotropin-releasing factor (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-07
    Description: In the adult castrated male rat, exposure to inescapable, intermittent electroshocks inhibited the pulsatile pattern of luteinizing hormone release and markedly lowered its plasma concentrations. The central administration of the corticotropin-releasing factor (CRF) antagonist alpha-helical ovine CRF residues 9 to 41 reversed the inhibitory action of stress. Neither its peripheral injection, nor the intraventricular injection of the inactive CRF analog des-Glu to Arg ovine CRF was effective. These results suggest that endogenous CRF may mediate some deleterious effects of noxious stimuli on reproduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rivier, C -- Rivier, J -- Vale, W -- AA03504/AA/NIAAA NIH HHS/ -- AM26741/AM/NIADDK NIH HHS/ -- HD13527/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):607-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003907" target="_blank"〉PubMed〈/a〉

    A mouse homeo box gene is expressed in spermatocytes and embryos (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-08
    Description: The MH-3 gene, which contains a homeo box that is expressed specifically in the adult testis, was identified and mapped to mouse chromosome 6. By means of in situ hybridization with adult testis sections and Northern blot hybridization with testis RNA from prepuberal mice and from Sl/Sld mutant mice, it was demonstrated that this gene is expressed in male germ cells during late meiosis. In the embryo, MH-3 transcripts were present at day 11.5 post coitum, a stage in mouse development when gonadal differentiation has not yet occurred. The MH-3 gene may have functions in spermatogenesis and embryogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rubin, M R -- Toth, L E -- Patel, M D -- D'Eustachio, P -- Nguyen-Huu, M C -- New York, N.Y. -- Science. 1986 Aug 8;233(4764):663-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3726554" target="_blank"〉PubMed〈/a〉

    Amplification and rearrangement of Hu-ets-1 in leukemia and lymphoma with involvement of 11q23 (1986)

    Differences in adrenergic recognition by pancreatic A and B cells (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-16
    Description: The adrenergic control of glucose homeostasis is mediated in part through variations in the release of pancreatic hormones. In this study, purified pancreatic A and B cells were used to identify the recognition and messenger units involved in the adrenergic regulation of glucagon and insulin release. Catecholamines induced beta-adrenergic receptor activity in A cells and alpha 2-adrenergic receptor activity in B cells. The two recognition units provoked opposite variations in the production of cellular cyclic adenosine monophosphate, the beta-adrenergic unit enhancing the nucleotide's permissive effect on amino acid-induced glucagon release and the alpha 2-adrenergic unit inhibiting that upon glucose-induced insulin release. In both cell types, catecholamines interact powerfully with the synergistic control of hormone release by nutrient- and (neuro)hormone-driven messenger systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schuit, F C -- Pipeleers, D G -- New York, N.Y. -- Science. 1986 May 16;232(4752):875-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2871625" target="_blank"〉PubMed〈/a〉

    A selective imidazobenzodiazepine antagonist of ethanol in the rat (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-12-05
    Description: Ethanol, at pharmacologically relevant concentrations of 20 to 100 mM, stimulates gamma-aminobutyric (GABA) receptor-mediated uptake of 36Cl-labeled chlorine into isolated brain vesicles. One drug that acts at GABA-benzodiazepine receptors, the imidazobenzodiazepine Ro15-4513, has been found to be a potent antagonist of ethanol-stimulated 36Cl- uptake into brain vesicles, but it fails to antagonize either pentobarbital- or muscimol-stimulated 36Cl- uptake. Pretreatment of rats with Ro15-4513 blocks the anticonflict activity of low doses of ethanol (but not pentobarbital) as well as the behavioral intoxication observed with higher doses of ethanol. The effects of Ro15-4513 in antagonizing ethanol-stimulated 36Cl- uptake and behavior are completely blocked by benzodiazepine receptor antagonists. However, other benzodiazepine receptor inverse agonists fail to antagonize the actions of ethanol in vitro or in vivo, suggesting a novel interaction of Ro15-4513 with the GABA receptor-coupled chloride ion channel complex. The identification of a selective benzodiazepine antagonist of ethanol-stimulated 36Cl- uptake in vitro that blocks the anxiolytic and intoxicating actions of ethanol suggests that many of the neuropharmacologic actions of ethanol may be mediated via central GABA receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzdak, P D -- Glowa, J R -- Crawley, J N -- Schwartz, R D -- Skolnick, P -- Paul, S M -- New York, N.Y. -- Science. 1986 Dec 5;234(4781):1243-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3022383" target="_blank"〉PubMed〈/a〉

    Male-killing bacteria in a parasitic wasp (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-28
    Description: A rod-shaped bacterium has been isolated that kills male eggs of the wasp Nasonia vitripennis, a pupal parasite of flies. Only some wasps of this species express this son-killer trait, and these wasps have bacterial infections in various organs. The bacterium was isolated from son-killer wasp tissue and from the hemolymph of fly pupae parasitized by wasps expressing the son-killer trait. Bacteria are apparently transferred to parasitized fly pupae during wasp oviposition, and developing wasp offspring are subsequently infected perorally. Sex-ratio distortion by microorganisms is found in a variety of plants and animals. The infectious peroral transmission of this trait variety of plants and animals. The infectious peroral transmission of this trait is in contrast to the typical pattern of cytoplasmic inheritance of sex-ratio distortion in these other systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Werren, J H -- Skinner, S W -- Huger, A M -- 5 T32 6MO7131/PHS HHS/ -- New York, N.Y. -- Science. 1986 Feb 28;231(4741):990-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3945814" target="_blank"〉PubMed〈/a〉

    Isolation and sequence of L3T4 complementary DNA clones: expression in T cells and brain (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-10-31
    Description: T lymphocytes express on their surface not only a specific receptor for antigen and major histocompatibility complex proteins, but also a number of additional glycoproteins that are thought to play accessory roles in the processes of recognition and signal transduction. L3T4 is one such T-cell surface protein that is expressed on most mouse thymocytes and on mature mouse T cells that recognize class II (Ia) major histocompatibility complex proteins. Such cells are predominantly of the helper/inducer phenotype. In this study, complementary DNA clones encoding L3T4 were isolated and sequenced. The predicted protein sequence shows that L3T4 is a member of the immunoglobulin gene superfamily. It is encoded by a single gene that does not require rearrangement prior to expression. Although the protein has not previously been demonstrated on nonhematopoietic cells, two messenger RNA species specific for L3T4 are found in brain. The minor species comigrates with the L3T4 transcript in T cells, whereas the major species is 1 kilobase smaller.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tourvieille, B -- Gorman, S D -- Field, E H -- Hunkapiller, T -- Parnes, J R -- 1 F32 CA07877-01/CA/NCI NIH HHS/ -- AI11313/AI/NIAID NIH HHS/ -- GM34991/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Oct 31;234(4776):610-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3094146" target="_blank"〉PubMed〈/a〉

Recent developments in biotechnology, such as the use of monoclonal antibodies and recombinant DNA, have the potential for providing both more extensive and detailed information on the parasite in the infected human and in insect vectors. New methods of detection, both in man and insect vectors, have been developed for two parasitic diseases, leishmaniasis and malaria.

    Diverse gene expression for isotypes of murine serum amyloid A protein during acute phase reaction (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-04-11
    Description: Serum amyloid A protein (SAA) is a precursor for a major component of amyloid fibrils, which, upon deposition, cause secondary amyloidosis in diseases such as rheumatoid arthritis. In mice, SAA is encoded by at least three genes, which show diverse expression during inflammation. Furthermore, in amyloidosis-resistant SJL mice, the gene expression for one SAA isotype, SAA2, is defective, although SAA2 gene expression is normal in amyloidosis-susceptible BALB/c mice. Because only SAA2-derived products deposit in mouse amyloid tissues, the resistance of SJL mice to amyloidosis seems to be due to defective SAA2 gene expression. Thus, the study emphasizes the importance of SAA gene structure in determining susceptibility to amyloidosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamamoto, K -- Shiroo, M -- Migita, S -- New York, N.Y. -- Science. 1986 Apr 11;232(4747):227-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3456645" target="_blank"〉PubMed〈/a〉

    Psychotomimesis mediated by kappa opiate receptors (1986)

    Publication Date: 1986-08-15
    Description: The kappa opioid agonists are analgesics that seem to be free of undesired morphine-like effects. Their dysphoric actions observed with the kappa agonist cyclazocine are thought to be mediated by an action at sigma-phencyclidine receptors. The benzomorphan kappa agonist MR 2033 is inactive at sigma-phencyclidine receptors. In male subjects, the opiate-active (-)-isomer, but not the (+)-isomer, elicited dose-dependent dysphoric and psychotomimetic effects that were antagonized by naloxone. Thus, kappa opiate receptors seem to mediate psychotomimetic effects. In view of the euphorigenic properties of mu agonists, our results imply the existence of opposed opioid systems affecting emotional and perceptual experiences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfeiffer, A -- Brantl, V -- Herz, A -- Emrich, H M -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):774-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3016896" target="_blank"〉PubMed〈/a〉

    Two magnetoreception pathways in a migratory salamander (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-15
    Description: Male eastern red-spotted newts (Notophthalmus viridescens) under controlled laboratory conditions exhibit unimodal magnetic compass orientation either in a trained compass direction or in the direction of their home pond. If the vertical component of the magnetic field is inverted, newts exhibiting the simple-compass response undergo a 180 degree reversal in orientation, whereas newts orienting in the home direction are unaffected by this treatment. These results indicate that newts use an axial compass mechanism for simple-compass orientation similar to that found in migrating birds. However, a distinct magnetoreception pathway with polar response properties is involved in homing and is possibly linked in some way to the navigational map.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phillips, J B -- 5T32MHI5793/MH/NIMH NIH HHS/ -- NS-19089/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):765-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3738508" target="_blank"〉PubMed〈/a〉

Genomic DNA's from 25 males with various red-green color vision deficiencies were analyzed by Southern blot hybridization with the cloned red and green pigment genes as probes.

    Human T-cell gamma chain genes: organization, diversity, and rearrangement (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-17
    Description: The human T-cell gamma chain genes have been characterized in an attempt to better understand their role in immune response. These immunoglobulin-like genes are encoded in the genome in variable, joining, and constant segments. The human gamma genes include at least six variable region genes, two joining segments, and two constant-region genes in germline DNA. Variable and joining segments recombine during the development of T cells to form rearranged genes. The diversity of human gamma genes produced by this recombinational mechanism is greater than that produced by the murine genome but is more limited than that of other immunoglobulin-like genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Quertermous, T -- Murre, C -- Dialynas, D -- Duby, A D -- Strominger, J L -- Waldman, T A -- Seidman, J G -- AI-15669/AI/NIAID NIH HHS/ -- AM-30241/AM/NIADDK NIH HHS/ -- T32-HL-07208/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Jan 17;231(4735):252-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3079918" target="_blank"〉PubMed〈/a〉

    Bioavailability of dioxin in soil from a 2,4,5-T manufacturing site (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-04-25
    Description: Dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin, TCDD) is a highly toxic contaminant produced in the manufacture of phenoxy herbicides. Despite its high TCDD content, soil from a contaminated area associated with a 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) manufacturing site in Newark, New Jersey, did not induce acute toxicity when administered to guinea pigs (the most sensitive species) by gavage. Analysis of liver samples demonstrated low bioavailability of TCDD from this soil. A comparative analysis of soils showed that Soxhlet extraction was necessary for the determination of TCDD on Newark soil, whereas solvent extraction was sufficient for soil from Times Beach, Missouri. The difference in the bioavailability of TCDD from these soils is correlated with TCDD extractability and may be related to the different compositions of the soils.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Umbreit, T H -- Hesse, E J -- Gallo, M A -- New York, N.Y. -- Science. 1986 Apr 25;232(4749):497-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3961492" target="_blank"〉PubMed〈/a〉

    A physiological role of epidermal growth factor in male reproductive function (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-29
    Description: Epidermal growth factor (EGF) stimulates the proliferation of various mammalian cells in culture, but its physiological role is not well defined. In mature male mice, large amounts of EGF are produced in the submandibular gland; it is present in the circulation at approximately 5 nanograms of EGF per milliliter of plasma. Sialoadenectomy (removal of the submandibular glands) decreased the amount of circulating EGF to an undetectable level but did not affect the circulating levels of testosterone or follicle-stimulating hormone. The number of mature sperm in the epididymis decreased by as much as 55 percent; the number of spermatids in the testis decreased by 40 to 50 percent; and the number of spermatocytes increased by about 20 percent. Administration of EGF to sialoadenectomized mice restored both the sperm content of the epididymis and the number of spermatids in the testis to normal. Thus, EGF may play a role in male reproductive function by stimulating the meiotic phase of spermatogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsutsumi, O -- Kurachi, H -- Oka, T -- New York, N.Y. -- Science. 1986 Aug 29;233(4767):975-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3090686" target="_blank"〉PubMed〈/a〉

    Description: A bovine rhodopsin complementary DNA probe was used to detect homologous visual pigment genes in a variety of species. Under stringent DNA hybridization conditions, genomic DNA from most vertebrate species carried a single homologous fragment. Additional homologies were detected in some vertebrates by reducing the hybridization stringency. Homologous fragments were also detected in DNA isolated from invertebrate species, a unicellular alga, and an archaebacterium; many of these fragments were homologous to a Drosophila opsin probe. These results suggest that photosensory pigments in a wide variety of species arose from a common precursor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, R L -- Wood, C -- Baehr, W -- Applebury, M L -- EY04801/EY/NEI NIH HHS/ -- EY07008/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jun 6;232(4755):1266-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3010467" target="_blank"〉PubMed〈/a〉

    Amplification and expression of genes associated with multidrug resistance in mammalian cells (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-09
    Description: In multidrug resistance, which is observed clinically and in tissue culture, cells that are challenged with certain cytotoxic drugs develop resistance not only to the selective agent but also to other, seemingly unrelated, agents. The multidrug-resistant phenotype is associated with DNA sequence amplification and with the overproduction of a number of cytosolic and membrane glycoproteins. The differential amplification and altered expression of at least two related genes, termed multidrug-resistant associated genes has been shown in multidrug-resistant Chinese hamster cells. In multidrug-resistant mouse and human cells, genes homologous to those in Chinese hamster cells are also amplified. The level of expression of these genes varied and did not correlate with their copy number. Furthermore, in Chinese hamster cells, the development of resistance to a single drug and multidrug resistance were closely related, but uncoupled, events. The overexpression of the multidrug-resistant genes was better correlated with the degree of resistance to the selective agent than it was with the extent of multidrug resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scotto, K W -- Biedler, J L -- Melera, P W -- CA-08748/CA/NCI NIH HHS/ -- CA-09207/CA/NCI NIH HHS/ -- CA-28595/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 May 9;232(4751):751-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2421411" target="_blank"〉PubMed〈/a〉

    Description: A semisterile male translocation heterozygote [t(2; 14) 1Gso] that exhibited neurological symptoms and an inability to swim (diver) was found among the offspring of male mice treated with triethylenemelamine. All breeding and cytogenetic data showed a complete concordance between translocation heterozygosity and the neurological disorders. Homozygosity for the translocation seemed to be lethal at an early embryonic stage. Despite the distinctive neurologic symptoms, no anatomic or histological defects in either the ear or in the central nervous system were observed. Thus, a balanced chromosomal translocation can produce disease with an inheritance pattern that mimics a single dominant gene defect.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rutledge, J C -- Cain, K T -- Cacheiro, N L -- Cornett, C V -- Wright, C G -- Generoso, W M -- New York, N.Y. -- Science. 1986 Jan 24;231(4736):395-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3941902" target="_blank"〉PubMed〈/a〉

    Amplification of an esterase gene is responsible for insecticide resistance in a California Culex mosquito (1986)

    Publication Date: 1986-08-15
    Description: An esterase gene from the mosquito Culex quinquefasciatus that is responsible for resistance to a variety of organophosphorus (OP) insecticides was cloned in lambda gt11 phage. This gene was used to investigate the genetic mechanism of the high production of the esterase B1 it encodes in OP-resistant Culex quinquefasciatus Say (Tem-R strain) from California. Adults of the Tem-R strain were found to possess at least 250 times more copies of the gene than adults of a susceptible strain (S-Lab). The finding that selection by pesticides may result in the amplification of genes encoding detoxifying enzymes in whole, normally developed, reproducing insects emphasizes the biological importance of this mechanism and opens new areas of investigation in pesticide resistance management.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mouches, C -- Pasteur, N -- Berge, J B -- Hyrien, O -- Raymond, M -- de Saint Vincent, B R -- de Silvestri, M -- Georghiou, G P -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):778-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3755546" target="_blank"〉PubMed〈/a〉

    Regulation by growth hormone of number of chondrocytes containing IGF-I in rat growth plate (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-01
    Description: Whether growth hormone stimulates longitudinal bone growth by a direct effect at the site of the growth plate or indirectly by increasing the concentration of circulating somatomedins (insulin-like growth factors) has been the subject of controversy. Immunohistochemical methods were used to explore the localization and distribution of insulin-like growth factor I (IGF-I) immunoreactivity in the epiphyseal growth plate of the proximal tibia of male rats. Cells in the proliferative zone of the growth plate of normal rats exhibited a bright immunofluorescence, whereas cells in the germinal and hypertrophic zones stained only weakly. In rats subjected to hypophysectomy, the number of fluorescent cells was markedly reduced. When the hypophysectomized rats were treated with growth hormone, either systemically or at the site of the growth plate, the number of IGF-I-immunoreactive cells in the proliferative zone was increased. The results show that IGF-I is produced in proliferative chondrocytes in the growth plate and that the number of IGF-I-containing cells is directly regulated by growth hormone. These findings suggest that IGF-I has a specific role in the clonal expansion of differentiated chondrocytes and exerts its function locally through autocrine or paracrine mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nilsson, A -- Isgaard, J -- Lindahl, A -- Dahlstrom, A -- Skottner, A -- Isaksson, O G -- New York, N.Y. -- Science. 1986 Aug 1;233(4763):571-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3523759" target="_blank"〉PubMed〈/a〉

    Females' choice of "good genotypes" as mates is promoted by an insect mating system (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-09-12
    Description: Can animal mating systems result in the choice of mates carrying genotypes that are otherwise favored by natural selection? This question is addressed by studying, in natural populations of Colias butterflies, how the phosphoglucose isomerase (PGI) enzyme genotype of males mating Colias females varies with degree of female mate discrimination. Certain PGI genotypes (as predicted from their biochemical properties) have been found previously to have an advantage in diverse fitness-related properties: flight capacity, survivorship, and overall mating success. It is shown here that males of these same genotypes have even greater advantage in remating older, more discriminating females than they do in mating previously unmated, less discriminating females. Assortative mating is not found and thus cannot explain this effect. The mating system of these insects does, at least in this case, result in active female choice of generally favorable male genotypes as mates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watt, W B -- Carter, P A -- Donohue, K -- GM 26758/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Sep 12;233(4769):1187-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3738528" target="_blank"〉PubMed〈/a〉

    Structure and diversity of the human T-cell receptor beta-chain variable region genes (1986)

    Details
    Publication Date: 1986-08-22
    Description: In order to characterize the variability of the expressed human T-cell receptor (TCR) beta-chain repertoire and contrast this variability to the known murine beta-chain repertoire, 15 independent complementary DNA (cDNA) clones containing TCR beta-chain variable region (V beta) genes were isolated from a human tonsil cDNA library. The nucleotide and derived amino acid sequences of these 15 V beta genes were analyzed together with 7 previously defined sequences. Fifteen different human V beta genes could be identified from 22 independent sequences. By means of DNA hybridization and sequence homology comparisons, it was possible to group these 15 genes into ten distinct V beta subfamilies, each containing from one to seven members. Minimal polymorphism was noted between individuals, except in multimember subfamilies. The amino acid sequences of these genes contain conserved amino acids that are also shared by murine TCR V beta genes and immunoglobulins; no features were found that distinguish human V beta genes from their murine counterparts. Evaluation of secondary structure showed that maximum variability coincides with generally hydrophilic portions of the amino acid sequence, while specific hydrophobic regions were conserved in all V beta genes examined.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tillinghast, J P -- Behlke, M A -- Loh, D Y -- 2-T32-AI00112/AI/NIAID NIH HHS/ -- GM 07200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Aug 22;233(4766):879-83.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3755549" target="_blank"〉PubMed〈/a〉

    CD8+ lymphocytes can control HIV infection in vitro by suppressing virus replication (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-12-19
    Description: Lymphocytes bearing the CD8 marker were shown to suppress replication of human immunodeficiency virus (HIV) in peripheral blood mononuclear cells. The effect was dose-dependent and most apparent with autologous lymphocytes; it did not appear to be mediated by a cytotoxic response. This suppression of HIV replication could be demonstrated by the addition of CD8+ cells at the initiation of virus production as well as after several weeks of virus replication by cultured cells. The observations suggest a potential approach to therapy in which autologous CD8 lymphocytes could be administered to individuals to inhibit HIV replication and perhaps progression of disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walker, C M -- Moody, D J -- Stites, D P -- Levy, J A -- New York, N.Y. -- Science. 1986 Dec 19;234(4783):1563-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2431484" target="_blank"〉PubMed〈/a〉

    Translocation of protein kinase C activity may mediate hippocampal long-term potentiation (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-07
    Description: Protein kinase C activity in rat hippocampal membranes and cytosol was determined 1 minute and 1 hour after induction of the synaptic plasticity of long-term potentiation. At 1 hour after long-term potentiation, but not at 1 minute, protein kinase C activity was increased twofold in membranes and decreased proportionately in cytosol, suggesting translocation of the activity. This time-dependent redistribution of enzyme activity was directly related to the persistence of synaptic plasticity, suggesting a novel mechanism regulating the strength of synaptic transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akers, R F -- Lovinger, D M -- Colley, P A -- Linden, D J -- Routtenberg, A -- MH25281/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):587-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003904" target="_blank"〉PubMed〈/a〉

    The brain nucleus locus coeruleus: restricted afferent control of a broad efferent network (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-11-07
    Description: Dense, focal injections of wheat germ agglutinin conjugated-horseradish peroxidase in the locus coeruleus of rats labeled afferent neurons in unexpectedly few brain regions. Major inputs emanate from only two nuclei--the paragigantocellularis and the prepositus hypoglossi, both in the rostral medulla. The dorsal cap of the paraventricular hypothalamic nucleus and the spinal intermediate gray are possible minor afferents to locus coeruleus. Other areas reported to project to locus coeruleus (for example, amygdala, nucleus tractus solitarius, and spinal dorsal horn) did not exhibit consistent retrograde labeling. Anterograde tracing and electrophysiologic experiments confirmed the absence of input to locus coeruleus from these areas, which instead terminate in targets adjacent to locus coeruleus. These findings redefine the anatomic organization of the locus coeruleus, and have implications for hypotheses concerning the functions of this noradrenergic brain nucleus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aston-Jones, G -- Ennis, M -- Pieribone, V A -- Nickell, W T -- Shipley, M T -- NS20643/NS/NINDS NIH HHS/ -- NS22320/NS/NINDS NIH HHS/ -- NS23348/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Nov 7;234(4777):734-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3775363" target="_blank"〉PubMed〈/a〉

    Specific DNA probe for the diagnosis of Plasmodium falciparum malaria (1986)

    Details
    Publication Date: 1986-03-21
    Description: Malaria can be diagnosed either by direct microscopic examination of blood smears, which is time consuming and requires expertise, or by immunological techniques, which are effective but do not distinguish between past and present infections. In this study, a simple procedure was developed for spotting lysed blood from infected patients directly onto nitrocellulose paper and identifying the malaria species on the basis of hybridization of parasite DNA with a species-specific probe. A genomic DNA library of Plasmodium falciparum was screened to detect clones containing DNA sequences that are highly repeated within the parasite genome. Several such clones were further analyzed to identify those that hybridize specifically with P. falciparum DNA but not with DNA from humans, P. vivax, or P. cynomolgi. This technique appears to be sensitive enough to detect 10 picograms of purified P. falciparum DNA (equivalent to 100 parasites) and in field studies is able to detect approximately 40 parasites per microliter of blood.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barker, R H Jr -- Suebsaeng, L -- Rooney, W -- Alecrim, G C -- Dourado, H V -- Wirth, D F -- 2 PO1 AI 16305-06/AI/NIAID NIH HHS/ -- T32 AI 07167/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1986 Mar 21;231(4744):1434-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3513309" target="_blank"〉PubMed〈/a〉

    Parvalbumin in most gamma-aminobutyric acid-containing neurons of the rat cerebral cortex (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-28
    Description: gamma-Aminobutyric acid (GABA) is one of the major inhibitory neurotransmitters in the central nervous system. In the cerebral cortex, GABA-containing cells represent a subpopulation of interneurons. With semithin frozen sections, it is possible to demonstrate that most GABA neurons in the rat somatosensory cortex contain the calcium-binding protein parvalbumin and that parvalbumin is found virtually only in GABA neurons. Parvalbumin seems to influence the electrical properties and enzymatic machinery to modulate neuronal excitability and activity. The specific role of parvalbumin in GABA-containing cortical cells may be related to controlling the effectiveness of their inhibitory action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Celio, M R -- New York, N.Y. -- Science. 1986 Feb 28;231(4741):995-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3945815" target="_blank"〉PubMed〈/a〉

    Molecular cloning of the chicken progesterone receptor (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-15
    Description: To define the functional domains of the progesterone receptor required for gene regulation, complementary DNA (cDNA) clones encoding the chicken progesterone receptor have been isolated from a chicken oviduct lambda gt11 cDNA expression library. Positive clones expressed antigenic determinants that cross-reacted with six monospecific antibodies derived from two independent sources. A 36-amino acid peptide sequence obtained by microsequencing of purified progesterone receptor was encoded by nucleotide sequences in the longest cDNA clone. Analysis of the amino acid sequence of the progesterone receptor deduced from the cDNA clones revealed a cysteine-rich region that was homologous to a region found in the estrogen and glucocorticoid receptors and to the avian erythroblastosis virus gag-erb-A fusion protein. Northern blot analysis with chicken progesterone receptor cDNA's indicated the existence of at least three messenger RNA species. These messages were found only in oviduct and could be induced by estrogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conneely, O M -- Sullivan, W P -- Toft, D O -- Birnbaumer, M -- Cook, R G -- Maxwell, B L -- Zarucki-Schulz, T -- Greene, G L -- Schrader, W T -- O'Malley, B W -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):767-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2426779" target="_blank"〉PubMed〈/a〉

    Role of platelet-activating factor-acether in mediating guinea pig anaphylaxis (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-04-04
    Description: The pathophysiology of anaphylaxis is very complex, and the sequelae of events are not fully explained in terms of the effects of histamine and peptide leukotrienes alone. Platelet-activating factor (1-O-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine, PAF-acether) has been detected in animals undergoing anaphylaxis. Injection of synthetic PAF-acether induces similar effects, including bronchoconstriction, respiratory arrest, systemic hypotension, neutropenia, and thrombocytopenia. The results reported here demonstrate that the histamine- and leukotriene-independent component of guinea pig anaphylaxis in vivo and in isolated lung parenchymal strips in vitro is mediated by PAF-acether. However, PAF-acether is not responsible for the anaphylaxis-induced thrombocytopenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Darius, H -- Lefer, D J -- Smith, J B -- Lefer, A M -- HL-25575/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1986 Apr 4;232(4746):58-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3082008" target="_blank"〉PubMed〈/a〉

    T-lymphocyte priming and protection against Friend leukemia by vaccinia-retrovirus env gene recombinant (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-11-07
    Description: The current prevalence of the acquired immune deficiency syndrome in humans has provoked renewed interest in methods of protective immunization against retrovirus-induced diseases. In this study, a vaccinia-retrovirus recombinant vector was constructed to study mechanisms of immune protection against Friend virus leukemia in mice. The envelope (env) gene from Friend murine leukemia virus (F-MuLV) was inserted into the genome of a vaccinia virus expression vector. Infected cells synthesized gp85, the glycosylated primary product of the env gene. Processing to gp70 and p15E, and cell surface localization, were similar to that occurring in cells infected with F-MuLV. Mice inoculated with live recombinant vaccinia virus had an envelope-specific T-cell proliferative response and, after challenge with Friend virus complex, developed neutralizing antibody and cytotoxic T cells (CTL) and were protected against leukemia. In contrast, unimmunized and control groups developed a delayed neutralizing antibody response, but no detectable CTL, and succumbed to leukemia. Genes of the major histocompatibility complex influenced protection induced by the vaccinia recombinant but not that induced by attenuated N-tropic Friend virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Earl, P L -- Moss, B -- Morrison, R P -- Wehrly, K -- Nishio, J -- Chesebro, B -- New York, N.Y. -- Science. 1986 Nov 7;234(4777):728-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3490689" target="_blank"〉PubMed〈/a〉

    Genetic control of melatonin synthesis in the pineal gland of the mouse (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-31
    Description: Pineal melatonin may play an important role in regulation of vertebrate circadian rhythms and in human affective disorders. In some mammals, such as hamsters and sheep, melatonin is involved in photoperiodic time measurement and in control of reproduction. Although wild mice (Mus domesticus) and some wild-derived inbred strains of mice have melatonin in their pineal glands, several inbred strains of laboratory mice (for example, C57BL/6J) were found not to have detectable melatonin in their pineal glands. Genetic analysis suggests that melatonin deficiency in C57BL/6J mice results from mutations in two independently segregating, autosomal recessive genes. Synthesis of melatonin from serotonin in the pineal gland requires the enzymes N-acetyltransferase (NAT) and hydroxyindole-O-methyltransferase (HIOMT). Pineal glands from C57BL/6J mice have neither NAT nor HIOMT activity. These results suggest that the two genes involved in melatonin deficiency are responsible for the absence of normal NAT and HIOMT enzyme activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ebihara, S -- Marks, T -- Hudson, D J -- Menaker, M -- 13162/PHS HHS/ -- FO5TW03377/TW/FIC NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 31;231(4737):491-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3941912" target="_blank"〉PubMed〈/a〉

    Description: New methods were used to identify the abnormality in a patient who showed evidence of neuromuscular dysfunction on extensive clinical examination. The methods revealed that the lactate content of the patient's skeletal muscle does not decline normally after exercise and that his red cells are defective in lactate transport. These results suggest that skeletal muscle and erythrocyte membranes share the same genetic lactate transporter (or a common subunit), which is deficient in this patient. This defect may be a common cause of elevated serum creatine kinase levels, as seen in the patient described here and of unexplained episodes of rhabdomyolysis and myoglobinuria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fishbein, W N -- New York, N.Y. -- Science. 1986 Dec 5;234(4781):1254-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3775384" target="_blank"〉PubMed〈/a〉

    Infectious mutants of HTLV-III with changes in the 3' region and markedly reduced cytopathic effects (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-08
    Description: A variant of human T-lymphotropic virus type III (HTLV-III) is described that replicates but does not kill normal human T cells in vitro. This variant, designated X10-1, was derived from the genome of a cytopathic HTLV-III clone (pHXB2D) by excision of a 200-base pair segment in the 3' region of the virus, spanning the env and 3'-orf genes. Comparable variants with 55 to 109 base pairs deleted exclusively in 3'-orf produced, in contrast, virus that was extremely cytopathic. On the basis of these findings it is concluded that the 3'-orf gene is not required for cytopathogenicity or replication of HTLV-III. In addition, the results suggest that virus replication and cytotoxicity are not intrinsically coupled. Furthermore, since clone X10-1 retains the ability to trans-activate genes linked to the viral long terminal repeats, trans-activation per se is not responsible for T-cell killing by HTLV-III. These results also raise the possibility that the carboxyl terminus of the envelope gene of HTLV-III has a direct role in T-cell killing by this virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fisher, A G -- Ratner, L -- Mitsuya, H -- Marselle, L M -- Harper, M E -- Broder, S -- Gallo, R C -- Wong-Staal, F -- New York, N.Y. -- Science. 1986 Aug 8;233(4764):655-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014663" target="_blank"〉PubMed〈/a〉

    Three-year incidence of AIDS in five cohorts of HTLV-III-infected risk group members (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-28
    Description: The incidence of the acquired immune deficiency syndrome (AIDS) among persons infected with human T-lymphotropic virus type III (HTLV-III) was evaluated prospectively among 725 persons who were at high risk of AIDS and had enrolled before October 1982 in cohort studies of homosexual men, parenteral drug users, and hemophiliacs. A total of 276 (38.1 percent) of the subjects were either HTLV-III seropositive at enrollment or developed HTLV-III antibodies subsequently. AIDS had developed in 28 (10.1 percent) of the seropositive subjects before August 1985. By actuarial survival calculations, the 3-year incidence of AIDS among all HTLV-III seropositive subjects was 34.2 percent in the cohort of homosexual men in Manhattan, New York, and 14.9 percent (range 8.0 to 17.2 percent) in the four other cohorts. Out of 117 subjects followed for a mean of 31 months after documented seroconversion, five (all hemophiliacs) developed AIDS 28 to 62 months after the estimated date of seroconversion, supporting the hypothesis that there is a long latency between acquisition of viral infection and the development of clinical AIDS. This long latency could account for the significantly higher AIDS incidence in the New York cohort compared with other cohorts if the virus entered the New York homosexual population before it entered the populations from which the other cohorts were drawn. However, risk of AIDS development in different populations may also depend on the presence of as yet unidentified cofactors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goedert, J J -- Biggar, R J -- Weiss, S H -- Eyster, M E -- Melbye, M -- Wilson, S -- Ginzburg, H M -- Grossman, R J -- DiGioia, R A -- Sanchez, W C -- New York, N.Y. -- Science. 1986 Feb 28;231(4741):992-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003917" target="_blank"〉PubMed〈/a〉

    Trans-activator gene of HTLV-II induces IL-2 receptor and IL-2 cellular gene expression (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-16
    Description: The human T-lymphotropic viruses types I and II (HTLV-I and -II) have been etiologically linked with certain T-cell leukemias and lymphomas that characteristically display membrane receptors for interleukin-2. The relation of these viruses to this growth factor receptor has remained unexplained. It is demonstrated here that introduction of the trans-activator (tat) gene of HTLV-II into the Jurkat T-lymphoid cell line results in the induction of both interleukin-2 receptor and interleukin-2 gene expression. The coexpression of these cellular genes may play a role in the altering T-cell growth following retroviral infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greene, W C -- Leonard, W J -- Wano, Y -- Svetlik, P B -- Peffer, N J -- Sodroski, J G -- Rosen, C A -- Goh, W C -- Haseltine, W A -- 1R01CA369974-01AI/CA/NCI NIH HHS/ -- CA07580/CA/NCI NIH HHS/ -- CA40658/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 May 16;232(4752):877-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3010456" target="_blank"〉PubMed〈/a〉

    Stable amplified DNA in drug-resistant Leishmania exists as extrachromosomal circles (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-01
    Description: The relative stability of amplified DNA in drug-resistant Leishmania major was previously reported to be dependent on location, that is, unstable amplified DNA was extrachromosomal and stable amplified DNA was chromosomal. Leishmanial chromosomes have now been directly examined by means of orthogonal-field-alternation gel electrophoresis (OFAGE). The amplified DNA's in three resistant cell lines displayed unusual migration and were clearly extrachromosomal, regardless of whether the amplified DNA's were stable or unstable. Thus, contrary to conclusions from earlier studies of drug resistance in cultured animal cells, stable amplified DNA in Leishmania can be extrachromosomal. In addition, these amplified DNA's were shown to be circular on the basis of their resistance to exonuclease III digestion and their behavior on OFAGE. Their mobility was also greatly changed after treatment with topoisomerase II, suggesting that the amplified DNA's were either supercoiled or concatenated circles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garvey, E P -- Santi, D V -- New York, N.Y. -- Science. 1986 Aug 1;233(4763):535-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3726545" target="_blank"〉PubMed〈/a〉

    The role of mononuclear phagocytes in HTLV-III/LAV infection (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-07-11
    Description: Cells with properties characteristic of mononuclear phagocytes were evaluated for infectivity with five different isolates of the AIDS virus, HTLV-III/LAV. Mononuclear phagocytes cultured from brain and lung tissues of AIDS patients harbored the virus. In vitro-infected macrophages from the peripheral blood, bone marrow, or cord blood of healthy donors produced large quantities of virus. Virus production persisted for at least 40 days and was not dependent on host cell proliferation. Giant multinucleated cells were frequently observed in the macrophage cultures and numerous virus particles, often located within vacuole-like structures, were present in infected cells. The different virus isolates were compared for their ability to infect macrophages and T cells. Isolates from lung- and brain-derived macrophages had a significantly higher ability to infect macrophages than T cells. In contrast, the prototype HTLV-III beta showed a 10,000-fold lower ability to infect macrophages than T cells and virus production was one-tenth that in macrophage cultures infected with other isolates, indicating that a particular variant of HTLV-III/LAV may have a preferential tropism for macrophages or T cells. These results suggest that mononuclear phagocytes may serve as primary targets for infection and agents for virus dissemination and that these virus-infected cells may play a role in the pathogenesis of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gartner, S -- Markovits, P -- Markovitz, D M -- Kaplan, M H -- Gallo, R C -- Popovic, M -- New York, N.Y. -- Science. 1986 Jul 11;233(4760):215-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014648" target="_blank"〉PubMed〈/a〉

    Amitotic neuroblastoma cells used for neural implants in monkeys (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-09-26
    Description: The potential utility of cultured neuroblastoma cells as donor tissue for neutral implants into the mammalian brain has been examined. Cells from a human neuroblastoma cell line, IMR-32, were labeled with [3H]thymidine and chemically rendered amitotic. These differentiated IMR-32 cells were grafted into the hippocampi of five adult African Green monkeys, and graft survival was evaluated for up to 270 days after transplantation. Autoradiographically labeled grafted cells were identified in four animals. Processes from grafted cells could be followed for distances of up to 150 micrometers into the host brain. No evidence for neoplastic growth of the transplant was found. Thus, grafted neuroblastoma cells can survive for prolonged periods in the primate brain and may serve as a practical source of donor tissue for neural implants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gash, D M -- Notter, M F -- Okawara, S H -- Kraus, A L -- Joynt, R J -- New York, N.Y. -- Science. 1986 Sep 26;233(4771):1420-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3749886" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-10-31
    Description: The human B-lymphotropic virus (HBLV) has a double-stranded DNA genome of greater than 110 kilobase pairs, which is consistent with its morphological classification as a herpesvirus. A 9000-base pair cloned probe of HBLV detected specific sequences in DNA and RNA of infected cells but did not hybridize to the genomic DNA of other human herpesviruses including the Epstein-Barr virus, human cytomegalovirus, herpes simplex type I, and varicella-zoster virus. Conversely, while probes obtained from each of the known human herpesvirus readily detected the homologous viral DNA, they did not hybridize to genomic HBLV DNA. This evidence, in addition to serological and morphological distinctions and the biological effects of this virus demonstrate that HBLV is a novel human herpesvirus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Josephs, S F -- Salahuddin, S Z -- Ablashi, D V -- Schachter, F -- Wong-Staal, F -- Gallo, R C -- New York, N.Y. -- Science. 1986 Oct 31;234(4776):601-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3020691" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1986-09-05
    Description: One of the common neurological complications in patients with the acquired immune deficiency syndrome (AIDS) is a subacute encephalopathy with progressive dementia. By using the techniques of cocultivation for virus isolation, in situ hybridization, immunocytochemistry, and transmission electron microscopy, the identity of an important cell type that supports replication of the AIDS retrovirus in brain tissue was determined in two affected individuals. These cells were mononucleated and multinucleated macrophages that actively synthesized viral RNA and produced progeny virions in the brains of the patients. Infected brain macrophages may serve as a reservoir for virus and as a vehicle for viral dissemination in the infected host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koenig, S -- Gendelman, H E -- Orenstein, J M -- Dal Canto, M C -- Pezeshkpour, G H -- Yungbluth, M -- Janotta, F -- Aksamit, A -- Martin, M A -- Fauci, A S -- New York, N.Y. -- Science. 1986 Sep 5;233(4768):1089-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3016903" target="_blank"〉PubMed〈/a〉

The song rhythm difference between the parental species appears to be due to sex-linked genes, whereas the basic interpulse-interval difference is autosomally inherited. Hybrid females show selective preferences for artificially generated songs carrying intermediate "hybrid" characteristics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kyriacou, C P -- Hall, J C -- GM 21473/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Apr 25;232(4749):494-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3083506" target="_blank"〉PubMed〈/a〉

    Reductions in arterial diameter produced by chronic decreases in blood flow are endothelium-dependent (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-24
    Description: A 70 percent reduction in the rate of blood flow through the common carotid artery in rabbits caused a 21 percent decrease in the diameter of this artery within 2 weeks. The smooth muscle relaxant papaverine did not attenuate the response; therefore, such reductions in diameter probably reflect a structural modification of the arterial wall rather than sustained contraction of smooth muscle. This arterial response to reduced blood flow was abolished when the endothelium was removed from the vessels. It appears that the endothelium is essential for the compensatory arterial response to long-term changes in luminal blood flow rates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Langille, B L -- O'Donnell, F -- New York, N.Y. -- Science. 1986 Jan 24;231(4736):405-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3941904" target="_blank"〉PubMed〈/a〉
