    A detailed genetic map for the X chromosome of the malaria vector, Anopheles gambiae (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1993-07-30
    Beschreibung: Anopheles gambiae, the primary vector of human malaria in Africa, is responsible for approximately a million deaths per year, mostly of children. Despite its significance in disease transmission, this mosquito has not been studied extensively by genetic or molecular techniques. To facilitate studies on this vector, a genetic map has been developed that covers the X chromosome at an average resolution of 2 centimorgans. This map has been integrated with the chromosome banding pattern and used to localize a recessive, sex-linked mutation (white eye) to within 1 centimorgan of flanking markers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zheng, L -- Collins, F H -- Kumar, V -- Kafatos, F C -- New York, N.Y. -- Science. 1993 Jul 30;261(5121):605-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Developmental Biology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8342025" target="_blank"〉PubMed〈/a〉

    Beta-adrenergic receptor kinase-2 and beta-arrestin-2 as mediators of odorant-induced desensitization (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1993-02-05
    Beschreibung: beta-Adrenergic receptor kinase (beta ARK) and beta-arrestin function in the homologous or agonist-activated desensitization of G protein-coupled receptors. The isoforms beta ARK-2 and beta-arrestin-2 are highly enriched in and localized to the dendritic knobs and cilia of the olfactory receptor neurons where the initial events of olfactory signal transduction occur. Odorants induce a rapid and transient elevation of adenosine 3',5'-monophosphate (cAMP), which activates a nonspecific cation channel and produces membrane depolarization. Preincubation of rat olfactory cilia with antibodies raised against beta ARK-2 and beta-arrestin-2 increased the odorant-induced elevation of cAMP and attenuated desensitization. These results suggest that beta ARK-2 and beta-arrestin-2 mediate agonist-dependent desensitization in olfaction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, T M -- Arriza, J L -- Jaworsky, D E -- Borisy, F F -- Attramadal, H -- Lefkowitz, R J -- Ronnett, G V -- NS 01578-01/NS/NINDS NIH HHS/ -- NS-02131/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1993 Feb 5;259(5096):825-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Johns Hopkins Medical Institutions, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8381559" target="_blank"〉PubMed〈/a〉

    Colocalization of X-linked agammaglobulinemia and X-linked immunodeficiency genes (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1993-07-16
    Beschreibung: Mice that bear the X-linked immunodeficiency (xid) mutation have a B lymphocyte-specific defect resulting in an inability to make antibody responses to polysaccharide antigens. A backcross of 1114 progeny revealed the colocalization of xid with Bruton's agammaglobulinemia tyrosine kinase (btk) gene, which is implicated in the human immune deficiency, X-linked agammaglobulinemia. Mice that carry xid have a missense mutation that alters a highly conserved arginine near the amino-terminus of the btk protein, Btk. Because this region of Btk lies outside any obvious kinase domain, the xid mutation may define another aspect of tyrosine kinase function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thomas, J D -- Sideras, P -- Smith, C I -- Vorechovsky, I -- Chapman, V -- Paul, W E -- GM33160/GM/NIGMS NIH HHS/ -- HG00277/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1993 Jul 16;261(5119):355-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8332900" target="_blank"〉PubMed〈/a〉

    Transsynaptic expression of a presynaptic glutamate receptor during hippocampal long-term potentiation (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1993-10-15
    Beschreibung: Repetitive activation of excitatory synapses in the hippocampus produces a persistent enhancement of synaptic efficiency known as long-term potentiation (LTP). In anesthetized and in freely moving rats, the induction of LTP in the perforant path led to a transient increase in the amount of messenger RNA (mRNA) coding for a presynaptic glutamate receptor (GR33) in dentate granule cells. The amount of GR33 mRNA was increased for at least 5 hours after the induction of LTP but was indistinguishable from control values 1 day after induction. The N-methyl-D-aspartate receptor antagonist 2-aminophosphonovalerate prevented the induction of both LTP and the increase in GR33 mRNA. The amount of GR33 protein was increased in the mossy fiber terminal zone of dentate granule cells 5 hours after the induction of LTP. These results suggest that the induction of LTP in synapses at one stage in a neural network may lead to modification in synaptic function at the next stage in the network.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smirnova, T -- Laroche, S -- Errington, M L -- Hicks, A A -- Bliss, T V -- Mallet, J -- New York, N.Y. -- Science. 1993 Oct 15;262(5132):433-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de genetique moleculaire de la neurotransmission et des processus neurodegeneratifs, Centre National de la Recherche Scientifique (CNRS), Gif-sur-Yvette, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8105538" target="_blank"〉PubMed〈/a〉

    A linkage between DNA markers on the X chromosome and male sexual orientation (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1993-07-16
    Beschreibung: The role of genetics in male sexual orientation was investigated by pedigree and linkage analyses on 114 families of homosexual men. Increased rates of same-sex orientation were found in the maternal uncles and male cousins of these subjects, but not in their fathers or paternal relatives, suggesting the possibility of sex-linked transmission in a portion of the population. DNA linkage analysis of a selected group of 40 families in which there were two gay brothers and no indication of nonmaternal transmission revealed a correlation between homosexual orientation and the inheritance of polymorphic markers on the X chromosome in approximately 64 percent of the sib-pairs tested. The linkage to markers on Xq28, the subtelomeric region of the long arm of the sex chromosome, had a multipoint lod score of 4.0 (P = 10(-5), indicating a statistical confidence level of more than 99 percent that at least one subtype of male sexual orientation is genetically influenced.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hamer, D H -- Hu, S -- Magnuson, V L -- Hu, N -- Pattatucci, A M -- New York, N.Y. -- Science. 1993 Jul 16;261(5119):321-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Biochemistry, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8332896" target="_blank"〉PubMed〈/a〉
