    Identification of a thyroid hormone receptor that is pituitary-specific (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-07
    Description: Three cellular homologs of the v-erbA oncogene were previously identified in the rat; two of them encode high affinity receptors for the thyroid hormone triiodothyronine (T3). A rat complementary DNA clone encoding a T3 receptor form of the ErbA protein, called r-ErbA beta-2, was isolated. The r-ErbA beta-2 protein differs at its amino terminus from the previously described rat protein encoded by c-erbA beta and referred to as r-ErbA beta-1. Unlike the other members of the c-erbA proto-oncogene family, which have a wide tissue distribution, r-erbA beta-2 appears to be expressed only in the anterior pituitary gland. In addition, thyroid hormone downregulates r-erbA beta-2 messenger RNA but not r-erbA beta-1 messenger RNA in a pituitary tumor-derived cell line. The presence of a pituitary-specific form of the thyroid hormone receptor that may be selectively regulated by thyroid hormone could be important for the differential regulation of gene expression by T3 in the pituitary gland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodin, R A -- Lazar, M A -- Wintman, B I -- Darling, D S -- Koenig, R J -- Larsen, P R -- Moore, D D -- Chin, W W -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):76-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539642" target="_blank"〉PubMed〈/a〉

    Two NF1 translocations map within a 600-kilobase segment of 17q11.2 (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-02
    Description: Balanced translocations, each involving chromosome 17q11.2, have been described in two patients with von Recklinghausen neurofibromatosis (NF1). To better localize the end points of these translocation events, and the NF1 gene (NF1) itself, human cosmids were isolated and mapped in the immediate vicinity of NF1. One cosmid probe, c11-1F10, demonstrated that both translocation breakpoints, and presumably NF1, are contained within a 600-kilobase Nru I fragment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Connell, P -- Leach, R -- Cawthon, R M -- Culver, M -- Stevens, J -- Viskochil, D -- Fournier, R E -- Rich, D C -- Ledbetter, D H -- White, R -- New York, N.Y. -- Science. 1989 Jun 2;244(4908):1087-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Utah, Salt Lake City 84132.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543077" target="_blank"〉PubMed〈/a〉

    Atriopeptin-immunoreactive neurons in the brain: presence in cardiovascular regulatory areas (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-03-01
    Description: Antisera to atriopeptin III and to a cyanogen bromide fragment of the precursor molecule atriopeptigen were prepared and used to examine the distribution of atriopeptin-like immunoreactive material in the heart and brain of the rat. Granules of this material were seen in myocytes throughout the right and left atria and were densest in the perinuclear region. The distribution of atriopeptin-like immunoreactive material in the heart is consistent with previous reports of atrial secretory granules. In the brain neurons containing the material were observed in the hypothalamus and the pontine tegmentum. Atriopeptin in the brain may serve as a neurotransmitter in neural systems controlling blood volume and composition, the same physiological functions regulated by blood-borne atriopeptin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saper, C B -- Standaert, D G -- Currie, M G -- Schwartz, D -- Geller, D M -- Needleman, P -- GM07200/GM/NIGMS NIH HHS/ -- NS00631/NS/NINDS NIH HHS/ -- NS18669/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1985 Mar 1;227(4690):1047-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2858127" target="_blank"〉PubMed〈/a〉

    Loss of M2 muscarine receptors in the cerebral cortex in Alzheimer's disease and experimental cholinergic denervation (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-31
    Description: Cerebral cortex samples from patients with Alzheimer's disease and from rats after experimental cholinergic denervation of the cerebral cortex exhibited reductions in the presynaptic marker choline acetyltransferase activity and in the number of M2 muscarine receptors, with no change in the number of M1 receptors. These results are in keeping with evidence that M2 receptors function in cholinergic nerve terminals to regulate the release of acetylcholine, whereas M1 receptors are located on postsynaptic cells and facilitate cellular excitation. New M1-selective agonists and M2-selective antagonists directed at post- or presynaptic sites deserve consideration as potential agents for the treatment of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mash, D C -- Flynn, D D -- Potter, L T -- HLO-7188/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1985 May 31;228(4703):1115-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3992249" target="_blank"〉PubMed〈/a〉

    Two mechanisms for the extinction of gene expression in hybrid cells (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-02
    Description: When two different mammalian cell types are fused to generate a stable hybrid cell line, genes that are active in only one of the parents are frequently shut off, a phenomenon called extinction. In this study two distinct, complementary mechanisms for such extinction of growth hormone gene expression were identified. In hybrids formed by fusing fibroblasts to pituitary cells, pituitary-specific proteins that bind to the growth hormone promoter were absent. In addition, a negative regulatory element located near the rat growth hormone promoter was specifically activated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tripputi, P -- Guerin, S L -- Moore, D D -- New York, N.Y. -- Science. 1988 Sep 2;241(4870):1205-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital, Boston.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2842865" target="_blank"〉PubMed〈/a〉

    Potassium channels in cardiac cells activated by arachidonic acid and phospholipids (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-09
    Description: Two types of potassium-selective channels activated by intracellular arachidonic acid or phosphatidylcholine have been found in neonatal rat atrial cells. In inside-out patches, arachidonic acid and phosphatidylcholine each opened outwardly rectifying potassium-selective channels with conductances of 160 picosiemens (IK.AA) and 68 picosiemens (IK.PC), respectively. These potassium channels were not sensitive to internally applied adenosine triphosphate (ATP), magnesium, or calcium. Lowering the intracellular pH from 7.2 to 6.8 or 6.4 reversibly increased IK.AA channel activity three- or tenfold, respectively. A number of fatty acid derivatives were tested for their ability to activate IK.AA. These potassium-selective channels may help explain the increase in potassium conductance observed in ischemic cells and raise the possibility that fatty acid derivatives act as second messengers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, D -- Clapham, D E -- HL 34873/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 9;244(4909):1174-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Mayo Foundation, Rochester, MN 55905.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2727703" target="_blank"〉PubMed〈/a〉

    Treatment with tin prevents the development of hypertension in spontaneously hypertensive rats (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-20
    Description: Cytochrome P-450-dependent metabolites of arachidonic acid (AA) increased in the kidneys of young, spontaneously hypertensive rats (SHRs) during the period of rapid elevation of blood pressure (BP) but not in adult SHRs or in Wistar Kyoto rats (WKYs) with normal BP. Treatment of SHRs and WKYs with stannous chloride (SnCl2), which selectively depletes renal cytochrome P-450, restored BP to normal, coincident with a natriuresis, in young but not in adult SHRs and did not affect either BP or sodium excretion in WKYs. Depletion of renal cytochrome P-450 was associated with decreased generation of these AA metabolites only in young SHRs. The antihypertensive effect of SnCl2 in young SHRs was greatly reduced by prevention of its cytochrome P-450-depleting action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sacerdoti, D -- Escalante, B -- Abraham, N G -- McGiff, J C -- Levere, R D -- Schwartzman, M L -- AM29742/AM/NIADDK NIH HHS/ -- HL25394/HL/NHLBI NIH HHS/ -- HL34300/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):388-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, New York Medical College, Valhalla 10595.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492116" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-11-03
    Description: Experimental allergic encephalomyelitis (EAE) is an autoimmune disease of the central nervous system mediated by CD4+ T cells reactive with myelin basic protein (MBP). Rats were rendered resistant to the induction of EAE by vaccination with synthetic peptides corresponding to idiotypic determinants of the beta chain VDJ region and J alpha regions of the T cell receptor (TCR) that are conserved among encephalitogenic T cells. These findings demonstrate the utility of TCR peptide vaccination for modulating the activity of autoreactive T cells and represent a general therapeutic approach for T cell-mediated pathogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Howell, M D -- Winters, S T -- Olee, T -- Powell, H C -- Carlo, D J -- Brostoff, S W -- New York, N.Y. -- Science. 1989 Nov 3;246(4930):668-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immune Response Corporation, San Diego, CA 92121.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2814489" target="_blank"〉PubMed〈/a〉

    Cloning and expression of a Xenopus embryonic gap junction protein (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-03
    Description: Gap junctions in the early amphibian embryo may play a fundamental role in the regulation of differentiation by mediating the cell-to-cell transfer of chemical signals. A complementary DNA encoding a gap junction present in Xenopus oocytes and early embryos has now been cloned and sequenced. This protein sequence is homologous to the well-characterized gap junction structural proteins rat connexin32 and connexin43. RNA blot analysis of total Xenopus oocyte RNA showed hybridization to a single 1.6-kilobase band. This messenger RNA is abundant in oocytes, decreases to levels below the sensitivity of our assay by stage 15 (18 hours), and is not detectable in RNA from a number of adult organs. To confirm that the oocyte cDNA encodes a gap junction channel, the protein was over expressed in Xenopus oocytes by injection of RNA synthesized in vitro. Pairs of RNA-injected oocytes formed many more time- and voltage-sensitive cell-cell channels than water-injected pairs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ebihara, L -- Beyer, E C -- Swenson, K I -- Paul, D L -- Goodenough, D A -- GM18974/GM/NIGMS NIH HHS/ -- GM37751/GM/NIGMS NIH HHS/ -- HL28958-06/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1194-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2466337" target="_blank"〉PubMed〈/a〉

    Nicotinic antagonists enhance process outgrowth by rat retinal ganglion cells in culture (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-03-11
    Description: Functional nicotinic cholinergic receptors are found on mammalian retinal ganglion cell neurons in culture. The neurotransmitter acetylcholine (ACh) can be detected in the medium of many of these retinal cultures, after release presumably from the choline acetyltransferase-positive amacrine cells. The postsynaptic effect of endogenous or applied ACh on the ganglion cells can be blocked with specific nicotinic antagonists. Here it is shown that within 24 hours of producing such a pharmacologic blockade, the retinal ganglion cells begin to sprout or regenerate neuronal processes. Thus, the growth-enhancing effect of nicotinic antagonists may be due to the removal of inhibition to growth by tonic levels of ACh present in the culture medium. Since there is a spontaneous leak of ACh in the intact retina, the effects of nicotinic cholinergic drugs on process outgrowth in culture may reflect a normal control mechanism for growth or regeneration of retinal ganglion cell processes that is exerted by ACh in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lipton, S A -- Frosch, M P -- Phillips, M D -- Tauck, D L -- Aizenman, E -- EY05477/EY/NEI NIH HHS/ -- EY06087/EY/NEI NIH HHS/ -- NS00879/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1988 Mar 11;239(4845):1293-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, Children's Hospital, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3344435" target="_blank"〉PubMed〈/a〉
