    A G protein mutant that inhibits thrombin and purinergic receptor activation of phospholipase A2 (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-10
    Description: The stimulation of phospholipase A2 by thrombin and type 2 (P2)-purinergic receptor agonists in Chinese hamster ovary cells is mediated by the G protein Gi. To delineate alpha chain regulatory regions responsible for control of phospholipase A2, chimeric cDNAs were constructed in which different lengths of the alpha subunit of Gs (alpha s) were replaced with the corresponding sequence of the Gi alpha subunit (alpha i2). When a carboxyl-terminal chimera alpha s-i(38), which has the last 38 amino acids of alpha s substituted with the last 36 residues of alpha i2, was expressed in Chinese hamster ovary cells, the receptor-stimulated phospholipase A2 activity was inhibited, although the chimera could still activate adenylyl cyclase. Thus, alpha s-i(38) is an active alpha s, but also a dominant negative alpha i molecule, indicating that the last 36 amino acids of alpha i2 are a critical domain for G protein regulation of phospholipase A2 activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gupta, S K -- Diez, E -- Heasley, L E -- Osawa, S -- Johnson, G L -- DK37871/DK/NIDDK NIH HHS/ -- GM30324/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Aug 10;249(4969):662-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Basic Sciences, National Jewish Center for Immunology and Respiratory Medicine, Denver, CO 80206.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2166341" target="_blank"〉PubMed〈/a〉

    Evidence of changes in protease sensitivity and subunit exchange rate on DNA binding by C/EBP (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-17
    Description: The transcription factor C/EBP uses a bipartite structural motif to bind DNA. Two protein chains dimerize through a set of amphipathic alpha helices termed the leucine zipper. Highly basic polypeptide regions emerge from the zipper to form a linked set of DNA contact surfaces. In the recently proposed a "scissors grip" model, the paired set of basic regions begin DNA contact at a central point and track in opposite directions along the major groove, forming a molecular clamp around DNA. This model predicts that C/EBP must undertake significant changes in protein conformation as it binds and releases DNA. The basic region of ligand-free C/EBP is highly sensitive to protease digestion. Pronounced resistance to proteolysis occurred when C/EBP associated with its specific DNA substrate. Sequencing of discrete proteolytic fragments showed that prominent sites for proteolysis occur at two junction points predicted by the "scissors grip" model. One junction corresponds to the cleft where the basic regions emerge from the leucine zipper. The other corresponds to a localized nonhelical segment that has been hypothesized to contain an N-cap and facilitate the sharp angulation necessary for the basic region to track continuously in the major groove of DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shuman, J D -- Vinson, C R -- McKnight, S L -- New York, N.Y. -- Science. 1990 Aug 17;249(4970):771-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Research Laboratories, Department of Embryology, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2202050" target="_blank"〉PubMed〈/a〉

    A cytosolic protein catalyzes the release of GDP from p21ras (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-04-06
    Description: The rate of release of guanine nucleotides from the ras proteins (Ras) is extremely slow in the presence of Mg2+. It seemed likely, therefore that a factor might exist to accelerate the release of guanosine diphosphate (GDP), and hence the exchange of GDP for guanosine triphosphate (GTP). Such a factor has now been discovered in rat brain cytosol. Brain cytosol was found to catalyze, by orders of magnitude, the release of guanine nucleotides from recombinant v-H-Ras protein bound with [alpha-32P]GDP. This effect occurred even in the presence of a large excess of Mg2+, but was destroyed by heat or by incubation of the cytosol for an hour at 37 degrees C in the absence of phosphatase inhibitors. The effect was observed with either v-H-Ras or c-H-Ras, but not with p25rab3A, a small G protein with about 30% similarity to Ras. The effect could not be mimicked by addition of recombinant Ras-GAP or purified GEF, a guanine nucleotide exchange factor involved in the regulation of eukaryotic protein synthesis. By gel filtration chromatography, the factor appears to possess a molecular size between 100,000 and 160,000 daltons. This protein (Ras-guanine nucleotide-releasing factor, or Ras-GRF) may be involved in the activation of p21ras.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolfman, A -- Macara, I G -- CA 43551/CA/NCI NIH HHS/ -- ES 01247/ES/NIEHS NIH HHS/ -- GM 41220/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Apr 6;248(4951):67-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biophysics, University of Rochester Medical Center, NY 14642.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2181667" target="_blank"〉PubMed〈/a〉

    Publication Date: 1990-05-18
    Description: Personal injury law is staggeringly inefficient as a system of victim compensation. There is little reason to assume that it importantly curtails unreasonably dangerous conduct, yet there is good reason to conclude that it promotes socially undesirable behavior. Moreover, the tort law system ill serves the goal of individual justice, in part because it assumes that lay juries can correctly decide complex scientific issues. Several methods of replacing tort law with other compensation systems are surveyed and a specific, balanced reform package is proposed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sugarman, S D -- New York, N.Y. -- Science. 1990 May 18;248(4957):823-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2343303" target="_blank"〉PubMed〈/a〉

    GT-1 binding site confers light responsive expression in transgenic tobacco (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-04-27
    Description: Light-dependent expression of rbcS, the gene encoding the small subunit of ribulose-1,5-bisphosphate carboxylase, which is the key enzyme involved in carbon fixation in higher plants, is regulated at the transcriptional level. Sequence analysis of the gene has uncovered a conserved GT motif in the -150 to -100 region of many rbcS promoters. This motif serves as the binding site of a nuclear factor, designated GT-1. Analysis of site-specific mutants of pea rbcS-3A promoter demonstrated that GT-1 binding in vitro is correlated with light-responsive expression of the rbcS promoter in transgenic plants. However, it is not known whether factors other than GT-1 might also be required for activation of transcription by light. A synthetic tetramer of box II (TGTGTGGTTAATATG), the GT-1 binding site located between -152 to -138 of the rbcS-3A promoter, inserted upstream of a truncated cauliflower mosaic virus 35S promoter is sufficient to confer expression in leaves of transgenic tobacco. This expression occurs principally in chloroplast-containing cells, is induced by light, and is correlated with the ability of box II to bind GT-1 in vitro. The data show that the binding site for GT-1 is likely to be a part of the molecular light switch for rbcS activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lam, E -- Chua, N H -- New York, N.Y. -- Science. 1990 Apr 27;248(4954):471-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Plant Molecular Biology, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2330508" target="_blank"〉PubMed〈/a〉

    Common modifications of trimeric G proteins and ras protein: involvement of polyisoprenylation (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-07-13
    Description: The heterotrimeric guanine nucleotide-binding regulatory proteins act at the inner surface of the plasma membrane to relay information from cell surface receptors to effectors inside the cell. These G proteins are not integral membrane proteins, yet are membrane associated. The processing and function of the gamma subunit of the yeast G protein involved in mating-pheromone signal transduction was found to be affected by the same mutations that block ras processing. The nature of these mutations implied that the gamma subunit was polyisoprenylated and that this modification was necessary for membrane association and biological activity. A microbial screen was developed for pharmacological agents that inhibit polyisoprenylation and that have potential application in cancer therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finegold, A A -- Schafer, W R -- Rine, J -- Whiteway, M -- Tamanoi, F -- CA 41996/CA/NCI NIH HHS/ -- GM 07183/GM/NIGMS NIH HHS/ -- GM 35827/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jul 13;249(4965):165-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1695391" target="_blank"〉PubMed〈/a〉

    Kinetics of gramicidin channel formation in lipid bilayers: transmembrane monomer association (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-30
    Description: Conducting gramicidin channels form predominantly by the transmembrane association of monomers, one from each side of a lipid bilayer. In single-channel experiments in planar bilayers the two gramicidin analogs, [Val1]gramicidin A (gA) and [4,4,4-F3-Val1]gramicidin A (F3gA), form dimeric channels that are structurally equivalent and have characteristically different conductances. When these gramicidins were added asymmetrically, one to each side of a preformed bilayer, the predominant channel type was the hybrid channel, formed between two chemically dissimilar monomers. These channels formed by the association of monomers residing in each half of the membrane. These results also indicate that the hydrophobic gramicidins are surprisingly membrane impermeant, a conclusion that was confirmed in experiments in which gA was added asymmetrically and symmetrically to preformed bilayers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Connell, A M -- Koeppe, R E 2nd -- Andersen, O S -- GM21342/GM/NIGMS NIH HHS/ -- GM34968/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1256-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Biophysics, Cornell University Medical College, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1700867" target="_blank"〉PubMed〈/a〉

    Description: Ten strains of a new arbovirus belonging to the Bunyamwera group (Bunyaviridae) were recovered from field-collected Aedes albopictus mosquitoes in Potosi, Missouri. This evidence indicates that this species may serve as an arbovirus vector in the United States. The urban-suburban distribution, aggressive biting behavior, and broad viral susceptibility of Ae. albopictus may lead to the transmission of viruses of known public health importance and perhaps of viruses hitherto not transmitted to humans because of the feeding pattern of their usual vectors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Francy, D B -- Karabatsos, N -- Wesson, D M -- Moore, C G Jr -- Lazuick, J S -- Niebylski, M L -- Tsai, T F -- Craig, G B Jr -- New York, N.Y. -- Science. 1990 Dec 21;250(4988):1738-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Vector-Borne Infectious Diseases, Centers for Disease Control, U.S. Public Health Service, Fort Collins, CO 80522.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2270489" target="_blank"〉PubMed〈/a〉

    DNA looping and unlooping by AraC protein (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-10-26
    Description: Expression of the L-arabinose BAD operon in Escherichia coli is regulated by AraC protein which acts both positively in the presence of arabinose to induce transcription and negatively in the absence of arabinose to repress transcription. The repression of the araBAD promoter is mediated by DNA looping between AraC protein bound at two sites near the promoter separated by 210 base pairs, araI and araO2. In vivo and in vitro experiments presented here show that an AraC dimer, with binding to half of araI and to araO2, maintains the repressed state of the operon. The addition of arabinose, which induces the operon, breaks the loop, and shifts the interactions from the distal araO2 site to the previously unoccupied half of the araI site. The conversion between the two states does not require additional binding of AraC protein and appears to be driven largely by properties of the protein rather than being specified by the slightly different DNA sequences of the binding sites. Slight reorientation of the subunits of AraC could specify looping or unlooping by the protein. Such a mechanism could account for regulation of DNA looping in other systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lobell, R B -- Schleif, R F -- GM18277/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Oct 26;250(4980):528-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Department of Biochemistry, Brandeis University, Waltham, MA 02254.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2237403" target="_blank"〉PubMed〈/a〉

    An insertion in the human thyrotropin receptor critical for high affinity hormone binding (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-09-21
    Description: Thyrotropin (TSH), luteinizing hormone (LH), and chorionic gonadotropin (CG) are structurally related glycoprotein hormones, which bind to receptors that share a high degree of sequence similarity. However, comparison of the primary amino acid sequences of the TSH and LH-CG receptors reveals two unique insertions of 8 and 50 amino acids in the extracellular domain of the TSH receptor. The functional significance of these insertions were determined by site-directed mutagenesis. Deletion of the 50-amino acid tract (residues 317 to 366) had no effect on TSH binding or on TSH and thyroid-stimulating immunoglobulin (TSI) biological activities. In contrast, either deletion or substitution of the eight-amino acid region (residues 38 to 45) abolished these activities. This eight-amino acid tract near the amino terminus of the TSH receptor appears to be an important site of interaction for both TSH and TSI.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wadsworth, H L -- Chazenbalk, G D -- Nagayama, Y -- Russo, D -- Rapoport, B -- DK-19289/DK/NIDDK NIH HHS/ -- DK-36182/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1990 Sep 21;249(4975):1423-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Veterans Administration Medical Center, San Francisco, CA 94121.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2169649" target="_blank"〉PubMed〈/a〉

    Defective presentation of endogenous antigen by a cell line expressing class I molecules (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-04-20
    Description: Cytotoxic T lymphocytes (CTLs) recognize class I major histocompatibility complex (MHC) molecules associated with antigenic peptides derived from endogenously synthesized proteins. Binding to such peptides is a requirement for class I assembly in the endoplasmic reticulum (ER). A mutant human cell line, T2, assembles and transports to its surface some, but not all, class I MHC molecules. The class I molecules expressed on the surface of T2 do not present peptides derived from cytosolic antigens, although they can present exogenously added peptides to CTL. The transported class I molecules may interact weakly with an unknown retaining factor in the ER such that they can assemble despite the relative shortage of peptides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hosken, N A -- Bevan, M J -- AI-19335/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1990 Apr 20;248(4953):367-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2326647" target="_blank"〉PubMed〈/a〉

    Direct interaction of a ligand for the erbB2 oncogene product with the EGF receptor and p185erbB2 (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-09-28
    Description: The erbB2 oncogene encodes a 185-kilodalton transmembrane protein whose sequence is similar to the epidermal growth factor receptor (EGFR). A 30-kilodalton factor (gp30) secreted from MDA-MB-231 human breast cancer cells was shown to be a ligand for p185erbB2. An antibody to EGFR abolished the tyrosine phosphorylation induced by EGF and transforming growth factor-alpha (TGF-alpha) but only partially blocked that produced by gp30 in SK-BR-3 breast cancer cells. In two cell lines that overexpress erbB2 but do not expresss EGFR (MDA-MB-453 breast cancer cells and a Chinese hamster ovary cell line that had been transfected with erbB2), phosphorylation of p185erbB2 was induced only by gp30. The gp30 specifically inhibited the growth of cells that overexpressed p185erbB2. An antibody to EGFR had no effect on the inhibition of SK-BR-3 cell colony formation obtained with gp30. Thus, it appeared that gp30 interacted directly with the EGFR and erbB2. Direct binding of gp30 to p185erbB2 was confirmed by binding competition experiments, where gp30 was found to displace the p185erbB2 binding of a specific antibody to p185erbB2. The evidence described here suggests that gp30 is a ligand for p185erbB2.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lupu, R -- Colomer, R -- Zugmaier, G -- Sarup, J -- Shepard, M -- Slamon, D -- Lippman, M E -- New York, N.Y. -- Science. 1990 Sep 28;249(4976):1552-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vincent T.

    Description: The amino acid sequences of three fragments of cyanogen bromide-digested human placental inositol 1,2-cyclic phosphate 2-phosphohydrolase, an enzyme of the phosphatidylinositol signaling pathway, are identical to sequences within lipocortin III, a member of a family of homologous calcium- and phospholipid-binding proteins that do not have defined physiological functions. Lipocortin III has also been previously identified as placental anticoagulant protein III (PAP III) and calcimedin 35 alpha. Antibodies to PAP III detected PAP III and inositol 1,2-cyclic phosphate 2-phosphohydrolase with identical reactivity on immunoblotting. In addition, inositol 1,2-cyclic phosphate 2-phosphohydrolase was stimulated by the same acidic phospholipids that bind lipocortins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ross, T S -- Tait, J F -- Majerus, P W -- HLBI 14147/HL/NHLBI NIH HHS/ -- HLBI 16634/HL/NHLBI NIH HHS/ -- HLBI 40801/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1990 May 4;248(4955):605-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Washington University School of Medicine, St Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2159184" target="_blank"〉PubMed〈/a〉

    Involvement of the silencer and UAS binding protein RAP1 in regulation of telomere length (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-10-26
    Description: The yeast protein RAP1, initially described as a transcriptional regulator, binds in vitro to sequences found in a number of seemingly unrelated genomic loci. These include the silencers at the transcriptionally repressed mating-type genes, the promoters of many genes important for cell growth, and the poly[(cytosine)1-3 adenine] [poly(C1-3A)] repeats of telomeres. Because RAP1 binds in vitro to the poly(C1-3A) repeats of telomeres, it has been suggested that RAP1 may be involved in telomere function in vivo. In order to test this hypothesis, the telomere tract lengths of yeast strains that contained conditionally lethal (ts) rap1 mutations were analyzed. Several rap1ts alleles reduced telomere length in a temperature-dependent manner. In addition, plasmids that contain small, synthetic telomeres with intact or mutant RAP1 binding sites were tested for their ability to function as substrates for poly(C1-3A) addition in vivo. Mutations in the RAP1 binding sites reduced the efficiency of the addition reaction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lustig, A J -- Kurtz, S -- Shore, D -- GM 40094/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Oct 26;250(4980):549-53.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Memorial Sloan-Kettering Cancer Center, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2237406" target="_blank"〉PubMed〈/a〉

    Description: The National Resident Matching Program is a centralized clearinghouse through which new medical graduates in the United States obtain their first positions. The history of this market, from the market failures that the centralized system was designed to address, to the present, is discussed, and a hypothesis about the behavior of such markets is presented. New evidence is then presented from a set of similar centralized markets in the United Kingdom. Because some of these latter markets have failed, while others have succeeded, they provide a natural experiment that permits the hypothesis to be tested. The new evidence also suggests directions in which modifications of existing procedures might be considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roth, A E -- New York, N.Y. -- Science. 1990 Dec 14;250(4987):1524-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Pittsburgh, PA 15260.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2274783" target="_blank"〉PubMed〈/a〉

    Recovery of mitogenic activity of a growth factor mutant with a nuclear translocation sequence (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-09-28
    Description: Heparin-binding growth factor-1 (HBGF-1) is an angiogenic polypeptide mitogen for mesoderm- and neuroectoderm-derived cells in vitro and remains biologically active after truncation of the amino-terminal domain (HBGF-1 alpha) of the HBGF-1 beta precursor. Polymerase chain reaction mutagenesis and prokaryotic expression systems were used to prepare a mutant of HBGF-1 alpha lacking a putative nuclear translocation sequence (amino acid residues 21 to 27; HBGF-1U). Although HBGF-1U retains its ability to bind to heparin, HBGF-1U fails to induce DNA synthesis and cell proliferation at concentrations sufficient to induce intracellular receptor-mediated tyrosine phosphorylation and c-fos expression. Attachment of the nuclear translocation sequence from yeast histone 2B at the amino terminus of HBGF-1U yields a chimeric polypeptide (HBGF-1U2) with mitogenic activity in vitro and indicates that nuclear translocation is important for this biological response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Imamura, T -- Engleka, K -- Zhan, X -- Tokita, Y -- Forough, R -- Roeder, D -- Jackson, A -- Maier, J A -- Hla, T -- Maciag, T -- HL 32348/HL/NHLBI NIH HHS/ -- HL 35627/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1990 Sep 28;249(4976):1567-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Biology, Jerome H.

    Intracellular calcium release mediated by sphingosine derivatives generated in cells (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-06-29
    Description: Soluble and hydrophobic lipid breakdown products have a variety of important signaling roles in cells. Here sphingoid bases derived in cells from sphingolipid breakdown are shown to have a potent and direct effect in mediating calcium release from intracellular stores. Sphingosine must be enzymically converted within the cell to a product believed to be sphingosine-1-phosphate, which thereafter effects calcium release from a pool including the inositol 1,4,5-trisphosphate-sensitive calcium pool. The sensitivity, molecular specificity, and reversibility of the effect on calcium movements closely parallel sphingoid base-mediated inhibition of protein kinase C. Generation of sphingoid bases in cells may activate a dual signaling pathway involving regulation of calcium and protein kinase C, comparable perhaps to the phosphatidylinositol and calcium signaling pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghosh, T K -- Bian, J -- Gill, D L -- NS19304/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jun 29;248(4963):1653-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, University of Maryland School of Medicine, Baltimore 21201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2163543" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1990-10-12
    Description: Voltage-dependent ion channels are responsible for electrical signaling in neurons and other cells. The main classes of voltage-dependent channels (sodium-, calcium-, and potassium-selective channels) have closely related molecular structures. For one member of this superfamily, the transiently voltage-activated Shaker H4 potassium channel, specific amino acid residues have now been identified that affect channel blockade by the small ion tetraethylammonium, as well as the conduction of ions through the pore. Furthermore, variation at one of these amino acid positions among naturally occurring potassium channels may account for most of their differences in sensitivity to tetraethylammonium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacKinnon, R -- Yellen, G -- GM 43949/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Oct 12;250(4978):276-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Physiology, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2218530" target="_blank"〉PubMed〈/a〉

    Translation initiation and ribosomal biogenesis: involvement of a putative rRNA helicase and RPL46 (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-03-02
    Description: Cold-sensitive mutations in the SPB genes (spb1-spb7) of Saccharomyces cerevisiae suppress the inhibition of translation initiation resulting from deletion of the poly(A)-binding protein gene (PAB1). The SPB4 protein belongs to a family of adenosine triphosphate (ATP)-dependent RNA helicases. The aberrant production of 25S ribosomal RNA (rRNA) occurring in spb4-1 mutants or the deletion of SPB2 (RPL46) permits the deletion of PAB1. These data suggest that mutations affecting different steps of 60S subunit formation can allow PAB-independent translation, and they indicate that further characterization of the spb mutations could lend insight into the biogenesis of the ribosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sachs, A B -- Davis, R W -- R37 GM 21891/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Mar 2;247(4946):1077-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford Medical Center, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2408148" target="_blank"〉PubMed〈/a〉

    Glucose, sulfonylureas, and neurotransmitter release: role of ATP-sensitive K+ channels (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-02-16
    Description: Sulfonylurea-sensitive adenosine triphosphate (ATP)-regulated potassium (KATP) channels are present in brain cells and play a role in neurosecretion at nerve terminals. KATP channels in substantia nigra, a brain region that shows high sulfonylurea binding, are inactivated by high glucose concentrations and by antidiabetic sulfonylureas and are activated by ATP depletion and anoxia. KATP channel inhibition leads to activation of gamma-aminobutyric acid (GABA) release, whereas KATP channel activation leads to inhibition of GABA release. These channels may be involved in the response of the brain to hyper- and hypoglycemia (in diabetes) and ischemia or anoxia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amoroso, S -- Schmid-Antomarchi, H -- Fosset, M -- Lazdunski, M -- New York, N.Y. -- Science. 1990 Feb 16;247(4944):852-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Pharmacologie Moleculaire et Cellulaire, UPR 411 du CNRS, Valbonne, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2305257" target="_blank"〉PubMed〈/a〉

    Effect of phospholipase C-gamma overexpression on PDGF-induced second messengers and mitogenesis (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-05-04
    Description: Platelet-derived growth factor (PDGF) stimulates phospholipase C (PLC) activity and the phosphorylation of the gamma isozyme of PLC (PLC-gamma) in vitro and in living cells. The role of PLC-gamma in the phosphoinositide signaling pathway was addressed by examining the effect of overexpression of PLC-gamma on cellular responses to PDGF. Overexpression of PLC-gamma correlated with PDGF-induced tyrosine phosphorylation of PLC-gamma and with PDGF-induced breakdown of phosphatidylinositol 4,5-bisphosphate (PIP2). However, neither bradykinin- nor lysophosphatidic acid-induced phosphoinositide metabolism was enhanced in the transfected cells, suggesting that the G protein-coupled phosphoinositide responses to these ligands are mediated by other PLC isozymes. The enhanced PDGF-induced generation of inositol trisphosphate (IP3) did not enhance intracellular calcium signaling or influence PDGF-induced DNA synthesis. Thus, enzymes other than PLC-gamma may limit PDGF-induced calcium signaling and DNA synthesis. Alternatively, PDGF-induced calcium signaling and DNA synthesis may use biochemical pathways other than phosphoinositide metabolism for signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Margolis, B -- Zilberstein, A -- Franks, C -- Felder, S -- Kremer, S -- Ullrich, A -- Rhee, S G -- Skorecki, K -- Schlessinger, J -- New York, N.Y. -- Science. 1990 May 4;248(4955):607-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rorer Biotechnology, King of Prussia, PA 19406.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2333512" target="_blank"〉PubMed〈/a〉

    Bovine growth hormone: human food safety evaluation (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-24
    Description: Scientists in the Food and Drug Administration (FDA), after reviewing the scientific literature and evaluating studies conducted by pharmaceutical companies, have concluded that the use of recombinant bovine growth hormone (rbGH) in dairy cattle presents no increased health risk to consumers. Bovine GH is not biologically active in humans, and oral toxicity studies have demonstrated that rbGH is not orally active in rats, a species responsive to parenterally administered bGH. Recombinant bGH treatment produces an increase in the concentration of insulin-like growth factor-I (IGF-I) in cow's milk. However, oral toxicity studies have shown that bovine IGF-I lacks oral activity in rats. Additionally, the concentration of IGF-I in milk of rbGH-treated cows is within the normal physiological range found in human breast milk, and IGF-I is denatured under conditions used to process cow's milk for infant formula. On the basis of estimates of the amount of protein absorbed intact in humans and the concentration of IGF-I in cow's milk during rbGH treatment, biologically significant levels of intact IGF-I would not be absorbed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Juskevich, J C -- Guyer, C G -- New York, N.Y. -- Science. 1990 Aug 24;249(4971):875-84.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Food and Drug Administration, Center for Veterinary Medicine, Office of New Animal Drug Evaluation, Rockville, MD 20857.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2203142" target="_blank"〉PubMed〈/a〉

    T cells responsive to myelin basic protein in patients with multiple sclerosis (1990)

    Details
    Publication Date: 1990-02-09
    Description: Gene mutation in vivo in human T lymphocytes appears to occur preferentially in dividing cells. Individuals with multiple sclerosis (MS) are assumed to have one or more populations of diving T cells that are being stimulated by autoantigens. Mutant T cell clones from MS patients were isolated and tested for reactivity to myelin basic protein, an antigen that is thought to participate in the induction of the disease. The hypoxanthine guanine phosphoribosyltransferase (hprt) clonal assay was used to determine mutant frequency values in MS patients with chronic progressive disease. Eleven of 258 thioguanine-resistant (hprt-) T cell clones from five of the six MS patients who were tested proliferated in response to human myelin basic protein without prior in vitro exposure to this antigen. No wild-type clones from these patients, nor any hprt- or wild-type clones from three healthy individuals responded to myelin basic protein. Thus, T cell clones that react with myelin basic protein can be isolated from the peripheral blood of MS patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allegretta, M -- Nicklas, J A -- Sriram, S -- Albertini, R J -- CA30688-07/CA/NCI NIH HHS/ -- NS00849/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1990 Feb 9;247(4943):718-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genetics Laboratory, University of Vermont, Burlington 05401.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1689076" target="_blank"〉PubMed〈/a〉

    A mouse model of the aniridia-Wilms tumor deletion syndrome (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-09
    Description: Deletion of chromosome 11p13 in humans produces the WAGR syndrome, consisting of aniridia (an absence or malformation of the iris), Wilms tumor (nephroblastoma), genitourinary malformations, and mental retardation. An interspecies backcross between Mus musculus/domesticus and Mus spretus was made in order to map the homologous chromosomal region in the mouse genome and to define an animal model of this syndrome. Nine evolutionarily conserved DNA clones from proximal human 11p were localized on mouse chromosome 2 near Small-eyes (Sey), a semidominant mutation that is phenotypically similar to aniridia. Analysis of Dickie's Small-eye (SeyDey), a poorly viable allele that has pleiotropic effects, revealed the deletion of three clones, f3, f8, and k13, which encompass the aniridia (AN2) and Wilms tumor susceptibility genes in man. Unlike their human counterparts, SeyDey/+ mice do not develop nephroblastomas. These findings suggest that the Small-eye defect is genetically equivalent to human aniridia, but that loss of the murine homolog of the Wilms tumor gene is not sufficient for tumor initiation. A comparison among Sey alleles suggests that the AN2 gene product is required for induction of the lens and nasal placodes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glaser, T -- Lane, J -- Housman, D -- 2 T32 GMO7753-11/GM/NIGMS NIH HHS/ -- GM27882/GM/NIGMS NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 9;250(4982):823-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Cancer Research, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2173141" target="_blank"〉PubMed〈/a〉

    HSP104 required for induced thermotolerance (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-06-01
    Description: A heat shock protein gene, HSP104, was isolated from Saccharomyces cerevisiae and a deletion mutation was introduced into yeast cells. Mutant cells grew at the same rate as wild-type cells and died at the same rate when exposed directly to high temperatures. However, when given a mild pre-heat treatment, the mutant cells did not acquire tolerance to heat, as did wild-type cells. Transformation with the wild-type gene rescued the defect of mutant cells. The results demonstrate that a particular heat shock protein plays a critical role in cell survival at extreme temperatures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sanchez, Y -- Lindquist, S L -- GM 35483/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jun 1;248(4959):1112-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular Genetics and Cell Biology, University of Chicago, Illinois 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2188365" target="_blank"〉PubMed〈/a〉

    Antibody-catalyzed porphyrin metallation (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-17
    Description: An antibody elicited to a distorted N-methyl porphyrin catalyzed metal ion chelation by the planar porphyrin. At fixed Zn2+ and Cu2+ concentrations, the antibody-catalyzed reaction showed saturation kinetics with respect to the substrate mesoporphyrin IX (2) and was inhibited by the hapten, N-methylmesoporphyrin IX (1). The turnover number of 80 hour-1 for antibody-catalyzed metallation of 2 with Zn2+ compares with an estimated value of 800 hour-1 for ferrochelatase. The antibody also catalyzed the insertion of Co2+ and Mn2+ into 2, but it did not catalyze the metallation of protoporphyrin IX (3) or deuteroporphyrin IX (4). The antibody has high affinity for several metalloporphyrins, suggesting an approach to developing antibody-heme catalysts for redox or electron transfer reactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cochran, A G -- Schultz, P G -- New York, N.Y. -- Science. 1990 Aug 17;249(4970):781-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2389144" target="_blank"〉PubMed〈/a〉

    Publication Date: 1990-09-28
    Description: Drug policy should strike the right balance between reducing the harm done by psychoactive drugs and reducing the harm that results from strict legal prohibitions and their enforcement. It is concluded, from a cost-benefit analysis based on pharmacologic, toxicologic, sociologic, and historical facts, that radical steps to repeal the prohibitions on presently illicit drugs would be likely, on balance, to make matters worse rather than better. Specific recommendations are offered for ameliorating the dangers to users and to society that are posed by each addictive drug.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldstein, A -- Kalant, H -- New York, N.Y. -- Science. 1990 Sep 28;249(4976):1513-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2218493" target="_blank"〉PubMed〈/a〉

    Transmembrane protein structure: spin labeling of bacteriorhodopsin mutants (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-06-01
    Description: Transmembrane proteins serve important biological functions, yet precise information on their secondary and tertiary structure is very limited. The boundaries and structures of membrane-embedded domains in integral membrane proteins can be determined by a method based on a combination of site-specific mutagenesis and nitroxide spin labeling. The application to one polypeptide segment in bacteriorhodopsin, a transmembrane chromoprotein that functions as a light-driven proton pump is described. Single cysteine residues were introduced at 18 consecutive positions (residues 125 to 142). Each mutant was reacted with a specific spin label and reconstituted into vesicles that were shown to be functional. The relative collision frequency of each spin label with freely diffusing oxygen and membrane-impermeant chromium oxalate was estimated with power saturation EPR (electron paramagnetic resonance) spectroscopy. The results indicate that residues 129 to 131 form a short water-exposed loop, while residues 132 to 142 are membrane-embedded. The oxygen accessibility for positions 131 to 138 varies with a periodicity of 3.6 residues, thereby providing a striking demonstration of an alpha helix. The orientation of this helical segment with respect to the remainder of the protein was determined.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altenbach, C -- Marti, T -- Khorana, H G -- Hubbell, W L -- AI 11479/AI/NIAID NIH HHS/ -- EY05216/EY/NEI NIH HHS/ -- GM28289/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jun 1;248(4959):1088-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jules Stein Eye Institute, University of California, Los Angeles 90024-7008.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2160734" target="_blank"〉PubMed〈/a〉

    Ligand-induced transformation by a noninternalizing epidermal growth factor receptor (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-02-23
    Description: Identification of a mutant epidermal growth factor (EGF) receptor that does not undergo downregulation has provided a genetic probe to investigate the role of internalization in ligand-induced mitogenesis. Contact-inhibited cells expressing this internalization-defective receptor exhibited a normal mitogenic response at significantly lower ligand concentrations than did cells expressing wild-type receptors. A transformed phenotype and anchorage-independent growth were observed at ligand concentrations that failed to elicit these responses in cells expressing wild-type receptors. These findings imply that activation of the protein tyrosine kinase activity at the cell membrane is sufficient for the growth-enhancing effects of EGF. Thus, downregulation can serve as an attenuation mechanism, without which transformation ensues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wells, A -- Welsh, J B -- Lazar, C S -- Wiley, H S -- Gill, G N -- Rosenfeld, M G -- DDK 13149/DK/NIDDK NIH HHS/ -- DDK 18477/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1990 Feb 23;247(4945):962-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of California-San Diego, La Jolla 92093.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2305263" target="_blank"〉PubMed〈/a〉

    Zinc mediation of the binding of human growth hormone to the human prolactin receptor (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-12-21
    Description: Human growth hormone (hGH) elicits a diverse set of biological activities including lactation that derives from binding to the prolactin (PRL) receptor. The binding affinity of hGH for the extracellular binding domain of the hPRL receptor (hPRLbp) was increased about 8000-fold by addition of 50 micromolar ZnCl2. Zinc was not required for binding of hGH to the hGH binding protein (hGHbp) or for binding of hPRL to the hPRLbp. Other divalent metal ions (Ca2+, Mg2+, Cu2+, Mn2+, and Co2+) at physiological concentrations did not support such strong binding. Scatchard analysis indicated a stoichiometry of one Zn2+ per hGH.hPRLbp complex. Mutational analysis showed that a cluster of three residues (His18, His21, and Glu174) in hGH and His188 from the hPRLbp (conserved in all PRL receptors but not GH receptors) are probable Zn2+ ligands. This polypeptide hormone.receptor "zinc sandwich" provides a molecular mechanism to explain why nonprimate GHs are not lactogenic and offers a molecular link between zinc deficiency and its association with altered functions of hGH.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cunningham, B C -- Bass, S -- Fuh, G -- Wells, J A -- New York, N.Y. -- Science. 1990 Dec 21;250(4988):1709-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Protein Engineering, Genentech, Inc., South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2270485" target="_blank"〉PubMed〈/a〉

    The enzymic nature of antibody catalysis: development of multistep kinetic processing (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-23
    Description: Detailed kinetic investigations of a catalytic antibody that promotes the hydrolyses of an anilide and phenyl ester show that this catalyst uses a multistep kinetic sequence resembling that found in serine proteases to hydrolyze its substrates, although antibody was elicited to a single transition-state analog. Like the serine proteases the antibody catalyzes the hydrolysis reactions through a putative covalent intermediate, but unlike the enzymes it may use hydroxide ion to cleave the intermediates. Nevertheless, the antibody is a potent catalyst with turnover at higher pH values rivaling that of chymotrypsin. This analysis also reveals that turnover by the antibody is ultimately limited by product desorption, suggesting that improvements in catalytic efficiency may be achieved by judicious changes in the structure of the substrate, so that it is not superimposable on that of the eliciting hapten.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benkovic, S J -- Adams, J A -- Borders, C L Jr -- Janda, K D -- Lerner, R A -- GM4385801/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 23;250(4984):1135-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pennsylvania State University, Department of Chemistry, University Park 16802.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2251500" target="_blank"〉PubMed〈/a〉

    Transplanted suprachiasmatic nucleus determines circadian period (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-02-23
    Description: The pacemaker role of the suprachiasmatic nucleus in a mammalian circadian system was tested by neural transplantation by using a mutant strain of hamster that shows a short circadian period. Small neural grafts from the suprachiasmatic region restored circadian rhythms to arrhythmic animals whose own nucleus had been ablated. The restored rhythms always exhibited the period of the donor genotype regardless of the direction of the transplant or genotype of the host. The basic period of the overt circadian rhythm therefore is determined by cells of the suprachiasmatic region.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ralph, M R -- Foster, R G -- Davis, F C -- Menaker, M -- HD13162/HD/NICHD NIH HHS/ -- HD18686/HD/NICHD NIH HHS/ -- MH09483/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1990 Feb 23;247(4945):975-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Virginia, Charlottesville 22903.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2305266" target="_blank"〉PubMed〈/a〉

    Publication Date: 1990-01-19
    Description: Asbestos is a commercial term for a group of fibrous minerals often associated with the development of pulmonary interstitial fibrosis (asbestosis), lung cancer, and malignant mesothelioma in occupationally exposed individuals. The pathogenicity of different forms of asbestos varies--long, thin amphibole fibers are most pathogenic, particularly in the induction of mesothelioma. Available data do not support the concept that low-level exposure to asbestos is a health hazard in buildings and schools. The concentration of asbestos fibers in air, type of asbestos, and size of fibers must be considered in evaluation of potential health risks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mossman, B T -- Bignon, J -- Corn, M -- Seaton, A -- Gee, J B -- R01 CA33501/CA/NCI NIH HHS/ -- R01 ES03878/ES/NIEHS NIH HHS/ -- R01 HL39469/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1990 Jan 19;247(4940):294-301.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Vermont, College of Medicine, Burlington 05405.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2153315" target="_blank"〉PubMed〈/a〉

    Induction of Salmonella stress proteins upon infection of macrophages (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-05-11
    Description: Regulated expression of bacterial genes allows a pathogen to adapt to new environmental conditions within the host. The synthesis of over 30 Salmonella proteins is selectively induced during infection of macrophages. Two proteins induced by Salmonella are the heat shock proteins GroEL and DnaK. Two avirulent, macrophage-sensitive mutants of Salmonella synthesize GroEL and DnaK but fail to synthesize different subsets of proteins normally induced within the macrophage. Enhanced expression of selected Salmonella proteins contributes to bacterial survival within macrophages and may also contribute to the apparent immunodominance of heat shock proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buchmeier, N A -- Heffron, F -- New York, N.Y. -- Science. 1990 May 11;248(4956):730-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1970672" target="_blank"〉PubMed〈/a〉
