    Circadian clock mutants of cyanobacteria (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-18
    Description: A diverse set of circadian clock mutants was isolated in a cyanobacterial strain that carries a bacterial luciferase reporter gene attached to a clock-controlled promoter. Among 150,000 clones of chemically mutagenized bioluminescent cells, 12 mutants were isolated that exhibit a broad spectrum of periods (between 16 and 60 hours), and 5 mutants were found that show a variety of unusual patterns, including arrhythmia. These mutations appear to be clock-specific. Moreover, it was demonstrated that in this cyanobacterium it is possible to clone mutant genes by complementation, which provides a means to genetically dissect the circadian mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kondo, T -- Tsinoremas, N F -- Golden, S S -- Johnson, C H -- Kutsuna, S -- Ishiura, M -- GM37040/GM/NIGMS NIH HHS/ -- MH43836/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1233-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute for Basic Biology, Okazaki, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973706" target="_blank"〉PubMed〈/a〉

    Engineering poliovirus as a vaccine vector for the expression of diverse antigens (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-02
    Description: As a step toward developing poliovirus as a vaccine vector, poliovirus recombinants were constructed by fusing exogenous peptides (up to 400 amino acids) and an artificial cleavage site for viral protease 3Cpro to the amino terminus of the viral polyprotein. Viral replication proceeded normally. An extended polyprotein was produced in infected cells and proteolytically processed into the complete array of viral proteins plus the foreign peptide, which was excluded from mature virions. The recombinants retained exogenous sequences through successive rounds of replication in culture and in vivo. Infection of animals with recombinants elicited a humoral immune response to the foreign peptides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andino, R -- Silvera, D -- Suggett, S D -- Achacoso, P L -- Miller, C J -- Baltimore, D -- Feinberg, M B -- AI22346/AI/NIAID NIH HHS/ -- AI35545/AI/NIAID NIH HHS/ -- RR00169/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1448-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, San Francisco.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073288" target="_blank"〉PubMed〈/a〉

    Drosophila TAFII150: similarity to yeast gene TSM-1 and specific binding to core promoter DNA (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-13
    Description: In Drosophila and human cells, the TATA binding protein (TBP) of the transcription factor IID (TFIID) complex is tightly associated with multiple subunits termed TBP-associated factors (TAFs) that are essential for mediating regulation of RNA polymerase II transcription. The Drosophila TAFII150 has now been molecularly cloned and biochemically characterized. The deduced primary amino acid sequence of dTAFII150 reveals a striking similarity to the essential yeast gene, TSM-1. Furthermore, like dTAFII150, the TSM-1 protein is found associated with the TBP in vivo, thus identifying the first yeast homolog of a TAF associated with TFIID. Both the product of TSM-1 and dTAFII150 bind directly to TBP and dTAFII250, demonstrating a functional similarity between human and yeast TAFs. Surprisingly, DNA binding studies indicate that purified recombinant dTAFII150 binds specifically to DNA sequences overlapping the start site of transcription. The data demonstrate that at least one of the TAFs is a sequence-specific DNA binding protein and that dTAFII150 together with TBP are responsible for TFIID interactions with an extended region of the core promoter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verrijzer, C P -- Yokomori, K -- Chen, J L -- Tjian, R -- New York, N.Y. -- Science. 1994 May 13;264(5161):933-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, Berkeley 94720-3202.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178153" target="_blank"〉PubMed〈/a〉

    Identification of herpesvirus-like DNA sequences in AIDS-associated Kaposi's sarcoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-16
    Description: Representational difference analysis was used to isolate unique sequences present in more than 90 percent of Kaposi's sarcoma (KS) tissues obtained from patients with acquired immunodeficiency syndrome (AIDS). These sequences were not present in tissue DNA from non-AIDS patients, but were present in 15 percent of non-KS tissue DNA samples from AIDS patients. The sequences are homologous to, but distinct from, capsid and tegument protein genes of the Gammaherpesvirinae, herpesvirus saimiri and Epstein-Barr virus. These KS-associated herpesvirus-like (KSHV) sequences appear to define a new human herpesvirus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, Y -- Cesarman, E -- Pessin, M S -- Lee, F -- Culpepper, J -- Knowles, D M -- Moore, P S -- New York, N.Y. -- Science. 1994 Dec 16;266(5192):1865-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, College of Physicians and Surgeons, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7997879" target="_blank"〉PubMed〈/a〉

    A genetic linkage map for the zebrafish (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-29
    Description: To facilitate molecular genetic analysis of vertebrate development, haploid genetics was used to construct a recombination map for the zebrafish Danio (Brachydanio) rerio. The map consists of 401 random amplified polymorphic DNAs (RAPDs) and 13 simple sequence repeats spaced at an average interval of 5.8 centimorgans. Strategies that exploit the advantages of haploid genetics and RAPD markers were developed that quickly mapped lethal and visible mutations and that placed cloned genes on the map. This map is useful for the position-based cloning of mutant genes, the characterization of chromosome rearrangements, and the investigation of evolution in vertebrate genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Postlethwait, J H -- Johnson, S L -- Midson, C N -- Talbot, W S -- Gates, M -- Ballinger, E W -- Africa, D -- Andrews, R -- Carl, T -- Eisen, J S -- 1RO1AI26734/AI/NIAID NIH HHS/ -- HD07470/HD/NICHD NIH HHS/ -- NS23915/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):699-703.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neurosciences, University of Oregon, Eugene 97403.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171321" target="_blank"〉PubMed〈/a〉

    Genetic control of programmed cell death in Drosophila (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-29
    Description: A gene, reaper (rpr), that appears to play a central control function for the initiation of programmed cell death (apoptosis) in Drosophila was identified. Virtually all programmed cell death that normally occurs during Drosophila embryogenesis was blocked in embryos homozygous for a small deletion that includes the reaper gene. Mutant embryos contained many extra cells and failed to hatch, but many other aspects of development appeared quite normal. Deletions that include reaper also protected embryos from apoptosis caused by x-irradiation and developmental defects. However, high doses of x-rays induced some apoptosis in mutant embryos, and the resulting corpses were phagocytosed by macrophages. These data suggest that the basic cell death program is intact although it was not activated in mutant embryos. The DNA encompassed by the deletion was cloned and the reaper gene was identified on the basis of the ability of cloned DNA to restore apoptosis to cell death defective embryos in germ line transformation experiments. The reaper gene appears to encode a small peptide that shows no homology to known proteins, and reaper messenger RNA is expressed in cells destined to undergo apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, K -- Grether, M E -- Abrams, J M -- Young, L -- Farrell, K -- Steller, H -- 5 F32 NS08536/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):677-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Brain and Cognitive Sciences, Cambridge, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171319" target="_blank"〉PubMed〈/a〉

    The Drosophila saxophone gene: a serine-threonine kinase receptor of the TGF-beta superfamily (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-25
    Description: The Drosophila decapentaplegic (dpp) gene encodes a transforming growth factor-beta (TGF-beta)-like protein that plays a key role in several aspects of development. Transduction of the DPP signal was investigated by cloning of serine-threonine kinase transmembrane receptors from Drosophila because this type of receptor is specific for the TGF-beta-like ligands. Here evidence is provided demonstrating that the Drosophila saxophone (sax) gene, a previously identified female sterile locus, encodes a TGF-beta-like type I receptor. Embryos from sax mothers and dpp embryos exhibit similar mutant phenotypes during early gastrulation, and these two loci exhibit genetic interactions, which suggest that they are utilized in the same pathway. These data suggest that sax encodes a receptor for dpp.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, T -- Finelli, A L -- Padgett, R W -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1756-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Waksman Institute, Rutgers University, Piscataway, NJ 08855-0759.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134837" target="_blank"〉PubMed〈/a〉

    Arabidopsis ABA response gene ABI1: features of a calcium-modulated protein phosphatase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-03
    Description: The Arabidopsis ABI1 locus is essential for a wide spectrum of abscisic acid (ABA) responses throughout plant development. Here, ABI1 was shown to regulate stomatal aperture in leaves and mitotic activity in root meristems. The ABI1 gene was cloned and predicted to encode a signaling protein. Although its carboxyl-terminal domain is related to serine-threonine phosphatase 2C, the ABI1 protein has a unique amino-terminal extension containing an EF hand calcium-binding site. These results suggest that the ABI1 protein is a Ca(2+)-modulated phosphatase and functions to integrate ABA and Ca2+ signals with phosphorylation-dependent response pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leung, J -- Bouvier-Durand, M -- Morris, P C -- Guerrier, D -- Chefdor, F -- Giraudat, J -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1448-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut des Sciences Vegetales, Centre National de la Recherche Scientifique UPR 40, Gif-sur-Yvette, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7910981" target="_blank"〉PubMed〈/a〉

    Coding of hemolysins within the ribosomal RNA repeat on a plasmid in Entamoeba histolytica (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-11
    Description: The pathogenesis of amoebic dysentery is a result of cytolysis of the colonic mucosa by the parasitic protozoan Entamoeba histolytica. The cytolysis results in extensive local ulceration and allows the amoeba to penetrate and metastasize to distant sites. Factors involved in this process were defined with three clones that express hemolytic activities in Escherichia coli.

    Fusion of a kinase gene, ALK, to a nucleolar protein gene, NPM, in non-Hodgkin's lymphoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-04
    Description: The 2;5 chromosomal translocation occurs in most anaplastic large-cell non-Hodgkin's lymphomas arising from activated T lymphocytes. This rearrangement was shown to fuse the NPM nucleolar phosphoprotein gene on chromosome 5q35 to a previously unidentified protein tyrosine kinase gene, ALK, on chromosome 2p23. In the predicted hybrid protein, the amino terminus of nucleophosmin (NPM) is linked to the catalytic domain of anaplastic lymphoma kinase (ALK). Expressed in the small intestine, testis, and brain but not in normal lymphoid cells, ALK shows greatest sequence similarity to the insulin receptor subfamily of kinases. Unscheduled expression of the truncated ALK may contribute to malignant transformation in these lymphomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morris, S W -- Kirstein, M N -- Valentine, M B -- Dittmer, K G -- Shapiro, D N -- Saltman, D L -- Look, A T -- CA 21765/CA/NCI NIH HHS/ -- KO8 CA 01702/CA/NCI NIH HHS/ -- P01 CA 20180/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 4;263(5151):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Oncology, St. Jude Children's Research Hospital, Memphis, TN 38105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8122112" target="_blank"〉PubMed〈/a〉

    A molecular determinant for submillisecond desensitization in glutamate receptors (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: The decay of excitatory postsynaptic currents in central neurons mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) receptors is likely to be shaped either by receptor desensitization or by offset after removal of glutamate from the synaptic cleft. Native AMPA receptors show desensitization time constants of 1 to about 10 milliseconds, but the underlying molecular determinants of these large differences are unknown. Cloned AMPA receptors carrying the "flop" splice variants of glutamate receptor subtype C (GluR-C) and GluR-D are shown to have desensitization time constants of around 1 millisecond, whereas those with the "flip" variants are about four times slower. Cerebellar granule cells switch their expression of GluR-D splice variants from mostly flip forms in early stages to predominantly flop forms in the adult rat brain. These findings suggest that rapid desensitization of AMPA receptors can be regulated by the expression and alternative splicing of GluR-D gene transcripts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mosbacher, J -- Schoepfer, R -- Monyer, H -- Burnashev, N -- Seeburg, P H -- Ruppersberg, J P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1059-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur medizinische Forschung, Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973663" target="_blank"〉PubMed〈/a〉

    Publication Date: 1994-04-08
    Description: The role of protein degradation in mitochondrial homeostasis was explored by cloning of a gene from Saccharomyces cerevisiae that encodes a protein resembling the adenosine triphosphate (ATP)-dependent bacterial protease Lon. The predicted yeast protein has a typical mitochondrial matrix-targeting sequence at its amino terminus. Yeast cells lacking a functional LON gene contained a nonfunctional mitochondrial genome, were respiratory-deficient, and lacked an ATP-dependent proteolytic activity present in the mitochondria of Lon+ cells. Lon- cells were also impaired in their ability to catalyze the energy-dependent degradation of several mitochondrial matrix proteins and they accumulated electron-dense inclusions in their mitochondrial matrix.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, C K -- Suda, K -- Wang, N -- Schatz, G -- New York, N.Y. -- Science. 1994 Apr 8;264(5156):273-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biozentrum der Universitat Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8146662" target="_blank"〉PubMed〈/a〉

    Association of intestinal peptide transport with a protein related to the cadherin superfamily (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-15
    Description: The first step in oral absorption of many medically important peptide-based drugs is mediated by an intestinal proton-dependent peptide transporter. This transporter facilitates the oral absorption of beta-lactam antibiotics and angiotensin-converting enzyme inhibitors from the intestine into enterocytes lining the luminal wall. A monoclonal antibody that blocked uptake of cephalexin was used to identify and clone a gene that encodes an approximately 92-kilodalton membrane protein that was associated with the acquisition of peptide transport activity by transport-deficient cells. The amino acid sequence deduced from the complementary DNA sequence of the cloned gene indicated that this transport-associated protein shares several conserved structural elements with the cadherin superfamily of calcium-dependent, cell-cell adhesion proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dantzig, A H -- Hoskins, J A -- Tabas, L B -- Bright, S -- Shepard, R L -- Jenkins, I L -- Duckworth, D C -- Sportsman, J R -- Mackensen, D -- Rosteck, P R Jr -- New York, N.Y. -- Science. 1994 Apr 15;264(5157):430-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, IN 46285.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8153632" target="_blank"〉PubMed〈/a〉

    Crystal structure of rat DNA polymerase beta: evidence for a common polymerase mechanism (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-24
    Description: Structures of the 31-kilodalton catalytic domain of rat DNA polymerase beta (pol beta) and the whole 39-kilodalton enzyme were determined at 2.3 and 3.6 angstrom resolution, respectively. The 31-kilodalton domain is composed of fingers, palm, and thumb subdomains arranged to form a DNA binding channel reminiscent of the polymerase domains of the Klenow fragment of Escherichia coli DNA polymerase I, HIV-1 reverse transcriptase, and bacteriophage T7 RNA polymerase. The amino-terminal 8-kilodalton domain is attached to the fingers subdomain by a flexible hinge. The two invariant aspartates found in all polymerase sequences and implicated in catalytic activity have the same geometric arrangement within structurally similar but topologically distinct palms, indicating that the polymerases have maintained, or possibly re-evolved, a common nucleotidyl transfer mechanism. The location of Mn2+ and deoxyadenosine triphosphate in pol beta confirms the role of the invariant aspartates in metal ion and deoxynucleoside triphosphate binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sawaya, M R -- Pelletier, H -- Kumar, A -- Wilson, S H -- Kraut, J -- CA17374/CA/NCI NIH HHS/ -- ES06839/ES/NIEHS NIH HHS/ -- GM10928/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1930-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, San Diego 92093-0317.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7516581" target="_blank"〉PubMed〈/a〉

    Modulation of epithelial cell growth by intraepithelial gamma delta T cells (1994)

    Publication Date: 1994-11-18
    Description: The role played in immune surveillance by gamma delta T cells residing in various epithelia has not been clear. It is shown here that activated gamma delta T cells obtained from skin and intestine express the epithelial cell mitogen keratinocyte growth factor (KGF). In contrast, intraepithelial alpha beta T cells, as well as all lymphoid alpha beta and gamma delta T cell populations tested, did not produce KGF or promote the growth of cultured epithelial cells. These results suggest that intraepithelial gamma delta T cells function in surveillance and in repair of damaged epithelial tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boismenu, R -- Havran, W L -- AI32751/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1253-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973709" target="_blank"〉PubMed〈/a〉

    Requirement of human renal water channel aquaporin-2 for vasopressin-dependent concentration of urine (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-01
    Description: Concentration of urine in mammals is regulated by the antidiuretic hormone vasopressin. Binding of vasopressin to its V2 receptor leads to the insertion of water channels in apical membranes of principal cells in collecting ducts. In nephrogenic diabetes insipidus (NDI), the kidney fails to concentrate urine in response to vasopressin. A male patient with an autosomal recessive form of NDI was found to be a compound heterozygote for two mutations in the gene encoding aquaporin-2, a water channel. Functional expression studies in Xenopus oocytes revealed that each mutation resulted in nonfunctional water channel proteins. Thus, aquaporin-2 is essential for vasopressin-dependent concentration of urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deen, P M -- Verdijk, M A -- Knoers, N V -- Wieringa, B -- Monnens, L A -- van Os, C H -- van Oost, B A -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Physiology, University of Nijmegen, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140421" target="_blank"〉PubMed〈/a〉

    Description: A homozygous mutation in the kinase domain of ZAP-70, a T cell receptor-associated protein tyrosine kinase, produced a distinctive form of human severe combined immunodeficiency. Manifestations of this disorder included profound immunodeficiency, absence of peripheral CD8+ T cells, and abundant peripheral CD4+ T cells that were refractory to T cell receptor-mediated activation. These findings demonstrate that ZAP-70 is essential for human T cell function and suggest that CD4+ and CD8+ T cells depend on different intracellular signaling pathways to support their development or survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elder, M E -- Lin, D -- Clever, J -- Chan, A C -- Hope, T J -- Weiss, A -- Parslow, T G -- AI29313/AI/NIAID NIH HHS/ -- GM43574/GM/NIGMS NIH HHS/ -- RR01271/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1596-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of California, San Francisco 94143-0110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202712" target="_blank"〉PubMed〈/a〉

    A protein phosphatase 2C involved in ABA signal transduction in Arabidopsis thaliana (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-03
    Description: The plant hormone abscisic acid (ABA) mediates various responses such as stomatal closure, the maintenance of seed dormancy, and the inhibition of plant growth. All three responses are affected in the ABA-insensitive mutant abi1 of Arabidopsis thaliana, suggesting that an early step in the signaling of ABA is controlled by the ABI1 locus. The ABI1 gene was cloned by chromosome walking, and a missense mutation was identified in the structural gene of the abi1 mutant.

    An interleukin-4-induced transcription factor: IL-4 Stat (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-16
    Description: Interleukin-4 (IL-4) is an immunomodulatory cytokine secreted by activated T lymphocytes, basophils, and mast cells. It plays an important role in modulating the balance of T helper (Th) cell subsets, favoring expansion of the Th2 lineage relative to Th1. Imbalance of these T lymphocyte subsets has been implicated in immunological diseases including allergy, inflammation, and autoimmune disease. IL-4 may mediate its biological effects, at least in part, by activating a tyrosine-phosphorylated DNA binding protein. This protein has now been purified and its encoding gene cloned. Examination of the primary amino acid sequence of this protein indicates that it is a member of the signal transducers and activators of transcription (Stat) family of DNA binding proteins, hereby designated IL-4 Stat. Study of the inhibitory activities of phosphotyrosine-containing peptides derived from the intracellular domain of the IL-4 receptor provided evidence for direct coupling of receptor and transcription factor during the IL-4 Stat activation cycle. Such observations indicate that IL-4 Stat has the same functional domain for both receptor coupling and dimerization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hou, J -- Schindler, U -- Henzel, W J -- Ho, T C -- Brasseur, M -- McKnight, S L -- New York, N.Y. -- Science. 1994 Sep 16;265(5179):1701-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tularik, Inc., South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8085155" target="_blank"〉PubMed〈/a〉

    Reconstitution of transcription factor SL1: exclusive binding of TBP by SL1 or TFIID subunits (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: RNA polymerase I and II transcription factors SL1 and TFIID, respectively, are composed of the TATA-binding protein (TBP) and a set of TBP-associated factors (TAFs) responsible for promoter recognition. How the universal transcription factor TBP becomes committed to a TFIID or SL1 complex has not been known. Complementary DNAs encoding each of the three TAFIs that are integral components of SL1 have not been isolated. Analysis of subunit interactions indicated that the three TAFIs can bind individually and specifically to TBP. In addition, these TAFIs interact with each other to form a stable TBP-TAF complex. When TBP was bound first by either TAFI110, 63, or 48, subunits of TFIID such as TAFII250 and 150 did not bind TBP. Conversely, if TBP first formed a complex with TAFII250 or 150, the subunits of SL1 did not bind TBP. These results suggest that a mutually exclusive binding specificity for TBP intrinsic to SL1 and TFIID subunits directs the formation of promoter- and RNA polymerase-selective TBP-TAF complexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Comai, L -- Zomerdijk, J C -- Beckmann, H -- Zhou, S -- Admon, A -- Tjian, R -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1966-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California at Berkeley 94720-3204.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801123" target="_blank"〉PubMed〈/a〉

    Description: Plant disease resistance genes function is highly specific pathogen recognition pathways. PRS2 is a resistance gene of Arabidopsis thaliana that confers resistance against Pseudomonas syringae bacteria that express avirulence gene avrRpt2. RPS2 was isolated by the use of a positional cloning strategy. The derived amino acid sequence of RPS2 contains leucine-rich repeat, membrane-spanning, leucine zipper, and P loop domains. The function of the RPS2 gene product in defense signal transduction is postulated to involve nucleotide triphosphate binding and protein-protein interactions and may also involve the reception of an elicitor produced by the avirulent pathogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bent, A F -- Kunkel, B N -- Dahlbeck, D -- Brown, K L -- Schmidt, R -- Giraudat, J -- Leung, J -- Staskawicz, B J -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1856-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091210" target="_blank"〉PubMed〈/a〉

    Suppression of hyphal formation in Candida albicans by mutation of a STE12 homolog (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-09
    Description: A Candida albicans gene (CPH1) was cloned that encodes a protein homologous to Saccharomyces cerevisiae Ste12p, a transcription factor that is the target of the pheromone response mitogen-activated protein kinase cascade. CPH1 complements both the mating defect of ste12 haploids and the filamentous growth defect of ste12/ste12 diploids. Candida albicans strains without a functional CPH1 gene (cph1/cph1) show suppressed hyphal formation on solid medium. However, cph1/cph1 strains can still form hyphae in liquid culture and in response to serum. Thus, filamentous growth may be activated in C. albicans by the same signaling kinase cascade that activates Ste12p in S. cerevisiae; however, alternative pathways may exist in C. albicans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, H -- Kohler, J -- Fink, G R -- GM402661/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1723-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7992058" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-27
    Description: The TATA-binding protein TBP appears to be essential for all transcription in eukaryotic cell nuclei, which suggests that its function was established early in evolution. Archaebacteria constitute a kingdom of organisms distinct from eukaryotes and eubacteria. Archaebacterial gene regulatory sequences often map to TATA box-like motifs. Here it is shown that the archaebacterium Pyrococcus woesei expresses a protein with structural and functional similarity to eukaryotic TBP molecules. This suggests that TBP's role in transcription was established before the archaebacterial and eukaryotic lineages diverged and that the transcription systems of archaebacteria and eukaryotes are fundamentally homologous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowlands, T -- Baumann, P -- Jackson, S P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 May 27;264(5163):1326-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome/CRC Institute, Cambridge, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8191287" target="_blank"〉PubMed〈/a〉

    Specification of pore properties by the carboxyl terminus of inwardly rectifying K+ channels (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-06
    Description: Inwardly rectifying potassium (K+) channels (IRKs) maintain the resting membrane potential of cells and permit prolonged depolarization, such as during the cardiac action potential. Inward rectification may result from block of the ion conduction pore by intracellular magnesium (Mgi2+). Two members of this family, IRK1 and ROMK1, which share 40 percent amino acid identity, differ markedly in single-channel K+ conductance and sensitivity to block by Mgi2+. The conserved H5 regions were hypothesized to determine these pore properties because they have this function in voltage-dependent K+ channels and in cyclic nucleotide-gated channels. However, exchange of the H5 region between IRK1 and ROMK1 had no effect on rectification and little or no effect on K+ conductance. By contrast, exchange of the amino- and carboxyl-terminal regions together transferred Mg2+ blockade and K+ conductance of IRK1 to ROMK1. Exchange of the carboxyl but not the amino terminus had a similar effect. Therefore, the carboxyl terminus appears to have a major role in specifying the pore properties of IRKs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taglialatela, M -- Wible, B A -- Caporaso, R -- Brown, A M -- HL36930/HL/NHLBI NIH HHS/ -- HL37044/HL/NHLBI NIH HHS/ -- NS23877/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 May 6;264(5160):844-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Physiology and Biophysics, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171340" target="_blank"〉PubMed〈/a〉

    cDNA cloning and interferon gamma down-regulation of proteasomal subunits X and Y (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-26
    Description: Proteasomes are the proteolytic complex responsible for major histocompatibility complex (MHC) class I-restricted antigen presentation. Interferon gamma treatment increases expression MHC-encoded LMP2 and LMP7 subunits of the proteasome and decreases expression of two proteasome subunits, named X and Y, which alters the proteolytic specificity of proteasomes. Molecular cloning of complementary DNAs encoding X and Y showed that their proteins are proteasomal subunits with high amino acid similarity to LMP7 and LMP2, respectively. Thus, interferon gamma may induce subunit replacements of X and Y by LMP7 and LMP2, respectively, producing proteasomes perhaps more appropriate for the immunological processing of endogenous antigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akiyama, K -- Yokota, K -- Kagawa, S -- Shimbara, N -- Tamura, T -- Akioka, H -- Nothwang, H G -- Noda, C -- Tanaka, K -- Ichihara, A -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1231-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Urology, School of Medicine, University of Tokushima, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066462" target="_blank"〉PubMed〈/a〉

    Description: Growth factor receptor-bound protein 2 (Grb2) links tyrosine-phosphorylated proteins to a guanine nucleotide releasing factor of the son of sevenless (Sos) class by attaching to the former by its Src homology 2 (SH2) moiety and to the latter by its SH3 domains. An isoform of grb2 complementary DNA (cDNA) was cloned that has a deletion in the SH2 domain. The protein encoded by this cDNA, Grb3-3, did not bind to phosphorylated epidermal growth factor receptor (EGFR) but retained functional SH3 domains and inhibited EGF-induced transactivation of a Ras-responsive element. The messenger RNA encoding Grb3-3 was expressed in high amounts in the thymus of rats at an age when massive negative selection of thymocytes occurs. Microinjection of Grb3-3 into Swiss 3T3 fibroblasts induced apoptosis. These findings indicate that Grb3-3, by acting as a dominant negative protein over Grb2 and by suppressing proliferative signals, may trigger active programmed cell death.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fath, I -- Schweighoffer, F -- Rey, I -- Multon, M C -- Boiziau, J -- Duchesne, M -- Tocque, B -- New York, N.Y. -- Science. 1994 May 13;264(5161):971-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rhone-Poulenc Rorer, Centre de Recherche de Vitry-Alfortville, Vitry sur Seine, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178156" target="_blank"〉PubMed〈/a〉

    Genetic dissection of complex traits (1994)

    Details
    Publication Date: 1994-09-30
    Description: Medical genetics was revolutionized during the 1980s by the application of genetic mapping to locate the genes responsible for simple Mendelian diseases. Most diseases and traits, however, do not follow simple inheritance patterns. Genetics have thus begun taking up the even greater challenge of the genetic dissection of complex traits. Four major approaches have been developed: linkage analysis, allele-sharing methods, association studies, and polygenic analysis of experimental crosses. This article synthesizes the current state of the genetic dissection of complex traits--describing the methods, limitations, and recent applications to biological problems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lander, E S -- Schork, N J -- HG00098/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2037-48.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091226" target="_blank"〉PubMed〈/a〉

    inhA, a gene encoding a target for isoniazid and ethionamide in Mycobacterium tuberculosis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-01-14
    Description: Isoniazid (isonicotinic acid hydrazide, INH) is one of the most widely used antituberculosis drugs, yet its precise target of action on Mycobacterium tuberculosis is unknown. A missense mutation within the mycobacterial inhA gene was shown to confer resistance to both INH and ethionamide (ETH) in M. smegmatis and in M. bovis. The wild-type inhA gene also conferred INH and ETH resistance when transferred on a multicopy plasmid vector to M. smegmatis and M. bovis BCG. The InhA protein shows significant sequence conservation with the Escherichia coli enzyme EnvM, and cell-free assays indicate that it may be involved in mycolic acid biosynthesis. These results suggest that InhA is likely a primary target of action for INH and ETH.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banerjee, A -- Dubnau, E -- Quemard, A -- Balasubramanian, V -- Um, K S -- Wilson, T -- Collins, D -- de Lisle, G -- Jacobs, W R Jr -- AI27160/AI/NIAID NIH HHS/ -- UO1AI30189/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):227-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Albert Einstein College of Medicine, Bronx, NY 10461.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8284673" target="_blank"〉PubMed〈/a〉

    Zinc finger phage: affinity selection of fingers with new DNA-binding specificities (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: A phage display system was developed and used to select zinc finger proteins with altered DNA-binding specificities. The three zinc fingers of the Zif268 protein were expressed on the surface of filamentous phage, and a library of variants was prepared by randomizing critical amino acids in the first zinc finger. Affinity selections, using DNA sites with base changes in the region recognized by the first finger, yielded Zif268 variants that bound tightly and specifically to the new sites. This phage system provides a tool for the study of protein-DNA interactions and may offer a general method for selecting zinc finger proteins that recognize desired target sites on double-stranded DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rebar, E J -- Pabo, C O -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):671-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303274" target="_blank"〉PubMed〈/a〉

    iaglu, a gene from Zea mays involved in conjugation of growth hormone indole-3-acetic acid (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-16
    Description: Plants contain most of the growth hormone indole-3-acetic acid (IAA) in conjugated forms believed to be inactive in promoting growth. The iaglu gene, which controls the first step in the biosynthesis of the IAA conjugates of Zea mays, encodes (uridine 5'-diphosphate-glucose:indol-3-ylacetyl)-beta-D-glucosyl transferase.

    Ku80: product of the XRCC5 gene and its role in DNA repair and V(D)J recombination (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-02
    Description: The radiosensitive mutant xrs-6, derived from Chinese hamster ovary cells, is defective in DNA double-strand break repair and in ability to undergo V(D)J recombination. The human XRCC5 DNA repair gene, which complements this mutant, is shown here through genetic and biochemical evidence to be the 80-kilodalton subunit of the Ku protein. Ku binds to free double-stranded DNA ends and is the DNA-binding component of the DNA-dependent protein kinase. Thus, the Ku protein is involved in DNA repair and in V(D)J recombination, and these results may also indicate a role for the Ku-DNA-dependent protein kinase complex in those same processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taccioli, G E -- Gottlieb, T M -- Blunt, T -- Priestley, A -- Demengeot, J -- Mizuta, R -- Lehmann, A R -- Alt, F W -- Jackson, S P -- Jeggo, P A -- AI 20047/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1442-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Children's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073286" target="_blank"〉PubMed〈/a〉

    Engineered biosynthesis of a complete macrolactone in a heterologous host (1994)

    Details
    Publication Date: 1994-07-22
    Description: Macrocyclic polyketides have been subjects of great interest in synthetic and biosynthetic chemistry because of their structural complexity and medicinal activities. With expression of the entire 6-deoxyerythronolide B synthase (DEBS) (10,283 amino acids) in a heterologous host, substantial quantities of 6-deoxyerythronolide B (6dEB), the aglycone of the macrolide antibiotic erythromycin, and 8,8a-deoxyoleandolide, a 14-membered lactone ring identical to 6dEB except for a methyl group side chain in place of an ethyl unit, were synthesized in Streptomyces coelicolor. The biosynthetic strategy utilizes a genetic approach that facilitates rapid structural manipulation of DEBS or other modular polyketide synthases (PKSs), including those found in actinomycetes with poorly developed genetic methods. From a technological viewpoint, this approach should allow the rational design of biosynthetic products and may eventually lead to the generation of diverse polyketide libraries by means of combinatorial cloning of naturally occurring and mutant PKS modules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kao, C M -- Katz, L -- Khosla, C -- New York, N.Y. -- Science. 1994 Jul 22;265(5171):509-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Stanford University, CA 94305-5025.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036492" target="_blank"〉PubMed〈/a〉

    Description: Scalable parallel computer architectures provide the computational performance needed for advanced biomedical computing problems. The National Institutes of Health have developed a number of parallel algorithms and techniques useful in determining biological structure and function. These applications include processing electron micrographs to determine the three-dimensional structure of viruses, calculating the solvent-accessible surface area of proteins to help predict the three-dimensional conformation of these molecules from their primary structures, and searching for homologous DNA or amino acid sequences in large biological databases. Timing results demonstrate substantial performance improvements with parallel implementations compared with conventional sequential systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martino, R L -- Johnson, C A -- Suh, E B -- Trus, B L -- Yap, T K -- New York, N.Y. -- Science. 1994 Aug 12;265(5174):902-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Computational Bioscience and Engineering Laboratory, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8052847" target="_blank"〉PubMed〈/a〉

    Sea urchin egg receptor for sperm: sequence similarity of binding domain and hsp70 (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-05
    Description: Fertilization depends on cell surface recognition proteins that interact and thereby mediate binding and subsequent fusion of the sperm and egg. Overlapping complementary DNA's encoding the egg plasma membrane receptor for sperm from the sea urchin Strongylocentrotus purpuratus were cloned and sequenced. Analysis of the deduced primary structure suggests that the receptor is a transmembrane protein with a short cytoplasmic domain. This domain showed no sequence similarity to known protein sequences. In contrast, the extracellular, sperm binding domain of the receptor did show sequence similarity to the heat shock protein 70 (hsp70) family of proteins. Recombinant protein representing this portion of the receptor bound to the sperm protein, binding, and also inhibited fertilization in a species-specific manner; beads coated with the protein became specifically bound to acrosome-reacted sperm. These data provide a basis for detailed investigations of molecular interactions that occur in gamete recognition and egg activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Foltz, K R -- Partin, J S -- Lennarz, W J -- HD18590/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1993 Mar 5;259(5100):1421-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of California, Santa Barbara 93106.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8383878" target="_blank"〉PubMed〈/a〉

    Origin recognition complex (ORC) in transcriptional silencing and DNA replication in S. cerevisiae (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-12-17
    Description: In Saccharomyces cerevisiae, the HMR-E silencer blocks site-specific interactions between proteins and their recognition sequences in the vicinity of the silencer. Silencer function is correlated with the firing of an origin of replication at HMR-E. An essential gene with a role in transcriptional silencing was identified by means of a screen for mutations affecting expression of HMR. This gene, known as ORC2, was shown to encode a component of the origin recognition complex that binds yeast origins of replication. A temperature-sensitive mutation in ORC2 disrupted silencing in cells grown at the permissive temperature. At the restrictive temperature, the orc2-1 mutation caused cell cycle arrest at a point in the cell cycle indicative of blocks in DNA replication. The orc2-1 mutation also resulted in the enhanced mitotic loss of a plasmid, suggestive of a defect in replication. These results provide strong evidence for an in vivo role of ORC in both chromosomal replication and silencing, and provide a link between the mechanism of silencing and DNA replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Foss, M -- McNally, F J -- Laurenson, P -- Rine, J -- GM31105/GM/NIGMS NIH HHS/ -- P30ES01896-12/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1993 Dec 17;262(5141):1838-44.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8266071" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1993-03-12
    Description: Glucagon and the glucagon receptor are a primary source of control over blood glucose concentrations and are especially important to studies of diabetes in which the loss of control over blood glucose concentrations clinically defines the disease. A complementary DNA clone for the glucagon receptor was isolated by an expression cloning strategy, and the receptor protein was expressed in several kidney cell lines. The cloned receptor bound glucagon and caused an increase in the intracellular concentration of adenosine 3', 5'-monophosphate (cAMP). The cloned glucagon receptor also transduced a signal that led to an increased concentration of intracellular calcium. The glucagon receptor is similar to the calcitonin and parathyroid hormone receptors. It can transduce signals leading to the accumulation of two different second messengers, cAMP and calcium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jelinek, L J -- Lok, S -- Rosenberg, G B -- Smith, R A -- Grant, F J -- Biggs, S -- Bensch, P A -- Kuijper, J L -- Sheppard, P O -- Sprecher, C A -- New York, N.Y. -- Science. 1993 Mar 12;259(5101):1614-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ZymoGenetics Inc., Seattle, WA 98105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8384375" target="_blank"〉PubMed〈/a〉

    Inhibition of Rev-mediated HIV-1 expression by an RNA binding protein encoded by the interferon-inducible 9-27 gene (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-02-26
    Description: Interferon inhibits expression of human immunodeficiency virus type-1 (HIV-1) through unknown mechanisms. A gene inducible by interferon-alpha (IFN-alpha) and interferon-gamma (IFN-gamma) was isolated by screening of a human complementary DNA library for proteins binding to the Rev-responsive element (RRE) of HIV-1. The product of this gene, RBP9-27, was shown to bind RNA in vitro and to inhibit HIV-1 expression after transfection into human cells. RBP9-27 primarily inhibited Rev-dependent posttranscriptional steps of viral gene expression. Thus, RBP9-27 is a cellular factor that antagonizes Rev function. These results suggest an interferon-induced antiviral mechanism operating through the induction of RNA binding proteins such as RBP9-27. Elucidation of RBP9-27 function may lead to a better understanding of the mechanism of interferon action during HIV-1 infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Constantoulakis, P -- Campbell, M -- Felber, B K -- Nasioulas, G -- Afonina, E -- Pavlakis, G N -- N0-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Feb 26;259(5099):1314-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Retrovirus Section, National Cancer Institute-Frederick Cancer Research and Development Center, MD 21702.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7680491" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1993-03-19
    Description: Many microorganisms, including Escherichia coli, can survive extended periods of starvation. The properties of cells that survived prolonged incubation in stationary phase were studied by mixture of 10-day-old (aged) cultures with 1-day-old (young) cultures of the same strain of Escherichia coli. Mutants from the aged cultures that could grow eventually took over the population, which resulted in the death of the cells from the young cultures. This phenotype was conferred by mutations in rpoS, which encodes a putative stationary phase-specific sigma factor. These rapid population shifts have implications for the studies of microbial evolution and ecology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zambrano, M M -- Siegele, D A -- Almiron, M -- Tormo, A -- Kolter, R -- New York, N.Y. -- Science. 1993 Mar 19;259(5102):1757-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7681219" target="_blank"〉PubMed〈/a〉

    Fusion between transcription factor CBF beta/PEBP2 beta and a myosin heavy chain in acute myeloid leukemia (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-08-20
    Description: The pericentric inversion of chromosome 16 [inv(16)(p13q22)] is a characteristic karyotypic abnormality associated with acute myeloid leukemia, most commonly of the M4Eo subtype. The 16p and 16q breakpoints were pinpointed by yeast artificial chromosome and cosmid cloning, and the two genes involved in this inversion were identified. On 16q the inversion occurred near the end of the coding region for CBF beta, also known as PEBP2 beta, a subunit of a heterodimeric transcription factor regulating genes expressed in T cells; on 16p a smooth muscle myosin heavy chain (SMMHC) gene (MYH11) was interrupted. In six of six inv(16) patient samples tested, an in-frame fusion messenger RNA was demonstrated that connected the first 165 amino acids of CBF beta with the tail region of SMMHC. The repeated coiled coil of SMMHC may result in dimerization of the CBF beta fusion protein, which in turn would lead to alterations in transcriptional regulation and contribute to leukemic transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, P -- Tarle, S A -- Hajra, A -- Claxton, D F -- Marlton, P -- Freedman, M -- Siciliano, M J -- Collins, F S -- CA55164/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Aug 20;261(5124):1041-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Internal Medicine, University of Michigan Medical Center, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8351518" target="_blank"〉PubMed〈/a〉

    Identification of the von Hippel-Lindau disease tumor suppressor gene (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-28
    Description: A gene discovered by positional cloning has been identified as the von Hippel-Lindau (VHL) disease tumor suppressor gene. A restriction fragment encompassing the gene showed rearrangements in 28 of 221 VHL kindreds. Eighteen of these rearrangements were due to deletions in the candidate gene, including three large nonoverlapping deletions. Intragenic mutations were detected in cell lines derived from VHL patients and from sporadic renal cell carcinomas. The VHL gene is evolutionarily conserved and encodes two widely expressed transcripts of approximately 6 and 6.5 kilobases. The partial sequence of the inferred gene product shows no homology to other proteins, except for an acidic repeat domain found in the procyclic surface membrane glycoprotein of Trypanosoma brucei.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Latif, F -- Tory, K -- Gnarra, J -- Yao, M -- Duh, F M -- Orcutt, M L -- Stackhouse, T -- Kuzmin, I -- Modi, W -- Geil, L -- New York, N.Y. -- Science. 1993 May 28;260(5112):1317-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunobiology, National Cancer Institute-Frederick Cancer Research and Development Center (NCI-FCRDC), Frederick, MD 21702-1201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8493574" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-30
    Description: A recessive mutation was identified in a family of transgenic mice that resulted in a reversal of left-right polarity (situs inversus) in 100 percent of the homozygous transgenic mice tested. Sequences that flanked the transgenic integration site were cloned and mapped to mouse chromosome 4, between the Tsha and Hxb loci. During early embryonic development, the direction of postimplantation turning, one of the earliest manifestations of left-right asymmetry, was reversed in homozygous transgenic embryos. This insertional mutation identifies a gene that controls embryonic turning and visceral left-right polarity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yokoyama, T -- Copeland, N G -- Jenkins, N A -- Montgomery, C A -- Elder, F F -- Overbeek, P A -- HD25340/HD/NICHD NIH HHS/ -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Apr 30;260(5108):679-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8480178" target="_blank"〉PubMed〈/a〉

    Requirement for a GTPase-activating protein in vesicle budding from the endoplasmic reticulum (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-05
    Description: The binding and hydrolysis of guanosine triphosphate (GTP) by the small GTP-binding protein Sar1p is required to form transport vesicles from the endoplasmic reticulum (ER) in Saccharomyces cerevisiae. Experiments revealed that an interaction between Sar1p and the Sec23p subunit of an oligomeric protein is also required for vesicle budding. The isolated Sec23p subunit and the oligomeric complex stimulated guanosine triphosphatase (GTPase) activity of Sar1p 10- to 15-fold but did not activate two other small GTP-binding proteins involved in vesicle traffic (Ypt1p and ARF). Activation of GTPase was inhibited by an antibody to Sec23p but not by an antibody that inhibits the budding activity of the other subunit of the Sec23p complex. Also, activation was thermolabile in pure samples of Sec23p that were isolated from two independent sec23 mutant strains. It appears that Sec23p represents a new class of GTPase-activating protein because its sequence shows no similarity to any known member of this family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshihisa, T -- Barlowe, C -- Schekman, R -- New York, N.Y. -- Science. 1993 Mar 5;259(5100):1466-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8451644" target="_blank"〉PubMed〈/a〉

    GDNF: a glial cell line-derived neurotrophic factor for midbrain dopaminergic neurons (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-21
    Description: A potent neurotrophic factor that enhances survival of midbrain dopaminergic neurons was purified and cloned. Glial cell line-derived neurotrophic factor (GDNF) is a glycosylated, disulfide-bonded homodimer that is a distantly related member of the transforming growth factor-beta superfamily. In embryonic midbrain cultures, recombinant human GDNF promoted the survival and morphological differentiation of dopaminergic neurons and increased their high-affinity dopamine uptake. These effects were relatively specific; GDNF did not increase total neuron or astrocyte numbers nor did it increase transmitter uptake by gamma-aminobutyric-containing and serotonergic neurons. GDNF may have utility in the treatment of Parkinson's disease, which is marked by progressive degeneration of midbrain dopaminergic neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, L F -- Doherty, D H -- Lile, J D -- Bektesh, S -- Collins, F -- New York, N.Y. -- Science. 1993 May 21;260(5111):1130-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Synergen, Inc., Boulder, CO 80301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8493557" target="_blank"〉PubMed〈/a〉

    Rapid assessment of drug susceptibilities of Mycobacterium tuberculosis by means of luciferase reporter phages (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-07
    Description: Effective chemotherapy of tuberculosis requires rapid assessment of drug sensitivity because of the emergence of multidrug-resistant Mycobacterium tuberculosis. Drug susceptibility was assessed by a simple method based on the efficient production of photons by viable mycobacteria infected with specific reporter phages expressing the firefly luciferase gene. Light production was dependent on phage infection, expression of the luciferase gene, and the level of cellular adenosine triphosphate. Signals could be detected within minutes after infection of virulent M. tuberculosis with reporter phages. Culture of conventional strains with antituberculosis drugs, including isoniazid or rifampicin, resulted in extinction of light production. In contrast, light signals after luciferase reporter phage infection of drug-resistant strains continued to be produced. Luciferase reporter phages may help to reduce the time required for establishing antibiotic sensitivity of M. tuberculosis strains from weeks to days and to accelerate screening for new antituberculosis drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobs, W R Jr -- Barletta, R G -- Udani, R -- Chan, J -- Kalkut, G -- Sosne, G -- Kieser, T -- Sarkis, G J -- Hatfull, G F -- Bloom, B R -- AI27235/AI/NIAID NIH HHS/ -- AI28927/AI/NIAID NIH HHS/ -- UO1AI30189/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1993 May 7;260(5109):819-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Albert Einstein College of Medicine, Bronx, NY 10461.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8484123" target="_blank"〉PubMed〈/a〉

    Molecular mechanism of transcription-repair coupling (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-02
    Description: Lesions in the transcribed strand block transcription and are repaired more rapidly than lesions in the nontranscribed (coding) strand which do not block RNA polymerase (RNAP). It has been shown previously that in Escherichia coli the mfd (mutation frequency decline) gene is necessary for strand-specific repair. The mfd gene was cloned and sequenced and the Mfd protein was purified and used to reconstitute strand-specific repair in a completely defined system. The mfd gene encodes a protein of 130 kilodaltons and contains the so-called "helicase motifs," a leucine zipper motif, and regions of sequence similarity to UvrB and RecG proteins. The Mfd protein was shown to (i) displace RNAP stalled at a lesion in an adenosine triphosphate-dependent reaction, (ii) bind to the damage recognition subunit (UvrA) of the excision nuclease, and (iii) stimulate the repair of the transcribed strand only when transcription is taking place. Thus, Mfd appears to target the transcribed strand for repair by recognizing a stalled RNAP and actively recruiting the repair enzyme to the transcription blocking lesion as it dissociates the stalled RNAP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Selby, C P -- Sancar, A -- New York, N.Y. -- Science. 1993 Apr 2;260(5104):53-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of North Carolina School of Medicine, Chapel Hill 27599.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8465200" target="_blank"〉PubMed〈/a〉

    Antagonism of catecholamine receptor signaling by expression of cytoplasmic domains of the receptors (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-05
    Description: The actions of many hormones and neurotransmitters are mediated by the members of a superfamily of receptors coupled to heterotrimeric guanine nucleotide-binding proteins (G proteins). These receptors are characterized by a highly conserved topographical arrangement in which seven transmembrane domains are connected by intracellular and extracellular loops. The interaction between these receptors and G proteins is mediated in large part by the third intracellular loop of the receptor. Coexpression of the third intracellular loop of the alpha 1B-adrenergic receptor with its parent receptor inhibited receptor-mediated activation of phospholipase C. The inhibition extended to the closely related alpha 1C-adrenergic receptor subtype, but not the phospholipase C-coupled M1 muscarinic acetylcholine receptor nor the adenylate cyclase-coupled D1A dopamine receptor. These results suggest that the receptor-G protein interface may represent a target for receptor antagonist drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luttrell, L M -- Ostrowski, J -- Cotecchia, S -- Kendall, H -- Lefkowitz, R J -- HL16037/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1993 Mar 5;259(5100):1453-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8383880" target="_blank"〉PubMed〈/a〉

    The Caenorhabditis elegans unc-17 gene: a putative vesicular acetylcholine transporter (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-07-30
    Description: Mutations in the unc-17 gene of the nematode Caenorhabditis elegans produce deficits in neuromuscular function. This gene was cloned and complementary DNAs were sequenced. On the basis of sequence similarity to mammalian vesicular transporters of biogenic amines and of localization to synaptic vesicles of cholinergic neurons in C. elegans, unc-17 likely encodes the vesicular transporter of acetylcholine. Mutations that eliminated all unc-17 gene function were lethal, suggesting that the acetylcholine transporter is essential. Molecular analysis of unc-17 mutations will allow the correlation of specific parts of the gene (and the protein) with observed functional defects. The mutants will also be useful for the isolation of extragenic suppressors, which could identify genes encoding proteins that interact with UNC-17.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alfonso, A -- Grundahl, K -- Duerr, J S -- Han, H P -- Rand, J B -- R01 GM038679/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Jul 30;261(5121):617-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Molecular and Cell Biology, Oklahoma Medical Research Foundation, Oklahoma City 73104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8342028" target="_blank"〉PubMed〈/a〉

    Released form of CNTF receptor alpha component as a soluble mediator of CNTF responses (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-19
    Description: The alpha component of the receptor for ciliary neurotrophic factor (CNTF) differs from other known growth factor receptors in that it is anchored to cell membranes by a glycosylphosphatidylinositol linkage. One possible function of this type of linkage is to allow for the regulated release of this receptor component. Cell lines not normally responsive to CNTF responded to treatment with a combination of CNTF and a soluble form of the CNTF alpha receptor component. These findings not only demonstrate that the CNTF receptor alpha chain is a required component of the functional CNTF receptor complex but also reveal that it can function in soluble form as part of a heterodimeric ligand. Potential physiological roles for the soluble CNTF receptor are suggested by its presence in cerebrospinal fluid and by its release from skeletal muscle in response to peripheral nerve injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S -- Aldrich, T H -- Ip, N Y -- Stahl, N -- Scherer, S -- Farruggella, T -- DiStefano, P S -- Curtis, R -- Panayotatos, N -- Gascan, H -- New York, N.Y. -- Science. 1993 Mar 19;259(5102):1736-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals, Inc., Tarrytown, NY 10591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7681218" target="_blank"〉PubMed〈/a〉

    DNA sequence determination by hybridization: a strategy for efficient large-scale sequencing (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-11
    Description: The concept of sequencing by hybridization (SBH) makes use of an array of all possible n-nucleotide oligomers (n-mers) to identify n-mers present in an unknown DNA sequence. Computational approaches can then be used to assemble the complete sequence. As a validation of this concept, the sequences of three DNA fragments, 343 base pairs in length, were determined with octamer oligonucleotides. Possible applications of SBH include physical mapping (ordering) of overlapping DNA clones, sequence checking, DNA fingerprinting comparisons of normal and disease-causing genes, and the identification of DNA fragments with particular sequence motifs in complementary DNA and genomic libraries. The SBH techniques may accelerate the mapping and sequencing phases of the human genome project.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drmanac, R -- Drmanac, S -- Strezoska, Z -- Paunesku, T -- Labat, I -- Zeremski, M -- Snoddy, J -- Funkhouser, W K -- Koop, B -- Hood, L -- New York, N.Y. -- Science. 1993 Jun 11;260(5114):1649-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biological and Medical Research Division, Argonne National Laboratory, IL 60439.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8503011" target="_blank"〉PubMed〈/a〉

    Ixr1, a yeast protein that binds to platinated DNA and confers sensitivity to cisplatin (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-07-30
    Description: Structure-specific recognition proteins (SSRPs) bind to DNA containing intrastrand cross-links formed by the anticancer drug cisplatin. A yeast gene encoding an SSRP, designated IXR1, was cloned and sequenced. The Ixr1 protein, a member of the high mobility group-box protein family, bound specifically to DNA modified with cisplatin but not inactive platinum compounds. A yeast strain with an inactivated IXR1 gene was half as sensitive to cisplatin and accumulated one-third as many platinum-DNA lesions after treatment with cisplatin as the parental strain. These findings suggest that SSRPs play a role in mediating the cytotoxicity of cisplatin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, S J -- Kellett, P J -- Lippard, S J -- New York, N.Y. -- Science. 1993 Jul 30;261(5121):603-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8342024" target="_blank"〉PubMed〈/a〉
