    Constitutively activated Jak-STAT pathway in T cells transformed with HTLV-I (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-07
    Beschreibung: Human T cell lymphotropic virus I (HTLV-I) is the etiological agent for adult T cell leukemia and tropical spastic paraparesis (also termed HTLV-I-associated myelopathy). HTLV-I-infected peripheral blood T cells exhibit an initial phase of interleukin-2 (IL-2)-dependent growth; over time, by an unknown mechanism, the cells become IL-2-independent. Whereas the Jak kinases Jak1 and Jak3 and the signal transducer and activator of transcription proteins Stat3 and Stat5 are activated in normal T cells in response to IL-2, this signaling pathway was constitutively activated in HTLV-I-transformed cells. In HTLV-I-infected cord blood lymphocytes, the transition from IL-2-dependent to IL-2-independent growth correlated with the acquisition of a constitutively activated Jak-STAT pathway, which suggests that this pathway participates in HTLV-I-mediated T cell transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Migone, T S -- Lin, J X -- Cereseto, A -- Mulloy, J C -- O'Shea, J J -- Franchini, G -- Leonard, W J -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):79-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunology, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7604283" target="_blank"〉PubMed〈/a〉

    FFA-1, a protein that promotes the formation of replication centers within nuclei (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-09-29
    Beschreibung: In the nuclei of eukaryotic cells, initiation of DNA replication occurs at a discrete number of foci. One component of these foci is the DNA replication factor RP-A. Here, the process leading to the association of RP-A with foci was reconstituted with cytosolic fractions derived from Xenopus eggs. With the use of this fractionated system, a 170-kilodalton protein required for the assembly of RP-A into foci was identified and purified. The protein appears to be an integral component of the foci at which replication of DNA is initiated in eukaryotic nuclei.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yan, H -- Newport, J -- GM33523/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 29;269(5232):1883-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of California, San Diego, Department of Biology, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569932" target="_blank"〉PubMed〈/a〉

    Dissociation of synchronization and excitability in furosemide blockade of epileptiform activity (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-10-06
    Beschreibung: Furosemide, a chloride cotransport inhibitor, reversibly blocked synchronized burst discharges in hippocampal slices without reducing the pyramidal cell response to single electrical stimuli. Images of the intrinsic optical signal acquired during these slice experiments indicated that furosemide coincidentally blocked changes in extracellular space. In urethane-anesthetized rats, systemically injected furosemide blocked kainic acid-induced electrical discharges recorded from cortex. These results suggest that (i) neuronal synchronization involved in epileptiform activity can be dissociated from synaptic excitability; (ii) nonsynaptic mechanisms, possibly associated with furosemide-sensitive cell volume regulation, may be critical for synchronization of neuronal activity; and (iii) agents that affect extracellular volume may have clinical utility as antiepileptic drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hochman, D W -- Baraban, S C -- Owens, J W -- Schwartzkroin, P A -- NS07144/NS/NINDS NIH HHS/ -- NS15317/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Oct 6;270(5233):99-102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurological Surgery, University of Washington, Seattle 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569957" target="_blank"〉PubMed〈/a〉

    A neuropeptide gene defined by the Drosophila memory mutant amnesiac (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-05-12
    Beschreibung: Mutations in genes required for associative learning and memory in Drosophila exist, but isolation of the genes has been difficult because most are defined by a single, chemically induced allele. Here, a simplified genetic screen was used to identify candidate genes involved in learning and memory. Second site suppressors of the dunce (dnc) female sterility phenotype were isolated with the use of transposon mutagenesis. One suppressor mutation that was recovered mapped in the amnesiac (amn) gene. Cloning of the locus revealed that amn encodes a previously uncharacterized neuropeptide gene. Thus, with the cloning of amn, specific neuropeptides are implicated in the memory process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feany, M B -- Quinn, W G -- New York, N.Y. -- Science. 1995 May 12;268(5212):869-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754370" target="_blank"〉PubMed〈/a〉

    Requirement of FGF-4 for postimplantation mouse development (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-13
    Beschreibung: Fibroblast growth factors (FGFs) are thought to influence many processes in vertebrate development because of their diverse sites of expression and wide range of biological activities in in vitro culture systems. As a means of elucidating embryonic functions of FGF-4, gene targeting was used to generate mice harboring a disrupted Fgf4 gene. Embryos homozygous for the null allele underwent uterine implantation and induced uterine decidualization but did not develop substantially thereafter. As was consistent with their behavior in vivo, Fgf4 null embryos cultured in vitro displayed severely impaired proliferation of the inner cell mass, whereas growth and differentiation of the inner cell mass were rescued when null embryos were cultured in the presence of FGF-4 protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feldman, B -- Poueymirou, W -- Papaioannou, V E -- DeChiara, T M -- Goldfarb, M -- HD21988/HD/NICHD NIH HHS/ -- HD27198/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 13;267(5195):246-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Integrated Program in Cellular, Molecular, and Biophysical Studies, Columbia University College of Physicians and Surgeons, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7809630" target="_blank"〉PubMed〈/a〉

    Mutations in Fas associated with human lymphoproliferative syndrome and autoimmunity (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-06-02
    Beschreibung: Fas (also known as Apo1 and CD95) is a cell surface receptor involved in apoptotic cell death. Fas expression and function were analyzed in three children (including two siblings) with a lymphoproliferative syndrome, two of whom also had autoimmune disorders. A large deletion in the gene encoding Fas and no detectable cell surface expression characterized the most affected patient. Clinical manifestations in the two related patients were less severe: Fas-mediated apoptosis was impaired and a deletion within the intracytoplasmic domain was detected. These findings illustrate the crucial regulatory role of Fas and may provide a molecular basis for some autoimmune diseases in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rieux-Laucat, F -- Le Deist, F -- Hivroz, C -- Roberts, I A -- Debatin, K M -- Fischer, A -- de Villartay, J P -- New York, N.Y. -- Science. 1995 Jun 2;268(5215):1347-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale (INSERM) U 429, Hopital Necker-Enfants Malades, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7539157" target="_blank"〉PubMed〈/a〉

    Aggressive behavior and altered amounts of brain serotonin and norepinephrine in mice lacking MAOA (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-06-23
    Beschreibung: Deficiency in monoamine oxidase A (MAOA), an enzyme that degrades serotonin and norepinephrine, has recently been shown to be associated with aggressive behavior in men of a Dutch family. A line of transgenic mice was isolated in which transgene integration caused a deletion in the gene encoding MAOA, providing an animal model of MAOA deficiency. In pup brains, serotonin concentrations were increased up to ninefold, and serotonin-like immunoreactivity was present in catecholaminergic neurons. In pup and adult brains, norepinephrine concentrations were increased up to twofold, and cytoarchitectural changes were observed in the somatosensory cortex. Pup behavioral alterations, including trembling, difficulty in righting, and fearfulness were reversed by the serotonin synthesis inhibitor parachlorophenylalanine. Adults manifested a distinct behavioral syndrome, including enhanced aggression in males.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2844866/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2844866/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cases, O -- Seif, I -- Grimsby, J -- Gaspar, P -- Chen, K -- Pournin, S -- Muller, U -- Aguet, M -- Babinet, C -- Shih, J C -- K05 MH 00796/MH/NIMH NIH HHS/ -- R01 MH 37020/MH/NIMH NIH HHS/ -- R37 MH 39085/MH/NIMH NIH HHS/ -- R37 MH039085/MH/NIMH NIH HHS/ -- R37 MH039085-23/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1995 Jun 23;268(5218):1763-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre National de la Recherche Scientifique (CNRS), Unite de Recherche Associee (URA), Institut Curie, Orsay, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7792602" target="_blank"〉PubMed〈/a〉

    Telomeres: beginning to understand the end (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-12-08
    Beschreibung: Telomeres are the protein-DNA structures at the ends of eukaryotic chromosomes. In yeast, and probably most other eukaryotes, telomeres are essential. They allow the cell to distinguish intact from broken chromosomes, protect chromosomes from degradation, and are substrates for novel replication mechanisms. Telomeres are usually replicated by telomerase, a telomere-specific reverse transcriptase, although telomerase-independent mechanisms of telomere maintenance exist. Telomere replication is both cell cycle- and developmentally regulated, and its control is likely to be complex. Because telomere loss causes the kinds of chromosomal changes associated with cancer and aging, an understanding of telomere biology has medical relevance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zakian, V A -- New York, N.Y. -- Science. 1995 Dec 8;270(5242):1601-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Princeton University, NJ 08544, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502069" target="_blank"〉PubMed〈/a〉

    The RNA component of human telomerase (1995)

    Details
    Publikationsdatum: 1995-09-01
    Beschreibung: Eukaryotic chromosomes are capped with repetitive telomere sequences that protect the ends from damage and rearrangements. Telomere repeats are synthesized by telomerase, a ribonucleic acid (RNA)-protein complex. Here, the cloning of the RNA component of human telomerase, termed hTR, is described. The template region of hTR encompasses 11 nucleotides (5'-CUAACCCUAAC) complementary to the human telomere sequence (TTAGGG)n. Germline tissues and tumor cell lines expressed more hTR than normal somatic cells and tissues, which have no detectable telomerase activity. Human cell lines that expressed hTR mutated in the template region generated the predicted mutant telomerase activity. HeLa cells transfected with an antisense hTR lost telomeric DNA and began to die after 23 to 26 doublings. Thus, human telomerase is a critical enzyme for the long-term proliferation of immortal tumor cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, J -- Funk, W D -- Wang, S S -- Weinrich, S L -- Avilion, A A -- Chiu, C P -- Adams, R R -- Chang, E -- Allsopp, R C -- Yu, J -- AG09383/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 1;269(5228):1236-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geron Corporation, Menlo Park, CA 94025, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7544491" target="_blank"〉PubMed〈/a〉

    Translational suppression by trinucleotide repeat expansion at FMR1 (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-05-05
    Beschreibung: Fragile X syndrome is the result of the unstable expansion of a trinucleotide repeat in the 5'-untranslated region of the FMR1 gene. Fibroblast subclones from a mildly affected patient, each containing stable FMR1 alleles with 57 to 285 CGG repeats, were shown to exhibit normal steady-state levels of FMR1 messenger RNA. However, FMR protein was markedly diminished from transcript with more than 200 repeats. Such transcripts were associated with stalled 40S ribosomal subunits. These results suggest that a structural RNA transition beyond 200 repeats impedes the linear 40S migration along the 5'-untranslated region. This results in translational inhibition by trinucleotide repeat expansion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, Y -- Zhang, F -- Lokey, L K -- Chastain, J L -- Lakkis, L -- Eberhart, D -- Warren, S T -- HD20521/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1995 May 5;268(5211):731-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Emory University School of Medicine, Atlanta, GA 30322.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7732383" target="_blank"〉PubMed〈/a〉

    Participation of the human beta-globin locus control region in initiation of DNA replication (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-11-03
    Beschreibung: The human beta-globin locus control region (LCR) controls the transcription, chromatin structure, and replication timing of the entire locus. DNA replication was found to initiate in a transcription-independent manner within a region located 50 kilobases downstream of the LCR in human, mouse, and chicken cells containing the entire human beta-globin locus. However, DNA replication did not initiate within a deletion mutant locus lacking the sequences that encompass the LCR. This mutant locus replicated in the 3' to 5' direction. Thus, interactions between distantly separated sequences can be required for replication initiation, and factors mediating this interaction appear to be conserved in evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aladjem, M I -- Groudine, M -- Brody, L L -- Dieken, E S -- Fournier, R E -- Wahl, G M -- Epner, E M -- New York, N.Y. -- Science. 1995 Nov 3;270(5237):815-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gene Expression Laboratory, Salk Institute, San Diego, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481774" target="_blank"〉PubMed〈/a〉

    Immune system impairment and hepatic fibrosis in mice lacking the dioxin-binding Ah receptor (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-05-05
    Beschreibung: The aryl hydrocarbon (Ah) receptor (AHR) mediates many carcinogenic and teratogenic effects of environmentally toxic chemicals such as dioxin. An AHR-deficient (Ahr-/-) mouse line was constructed by homologous recombination in embryonic stem cells. Almost half of the mice died shortly after birth, whereas survivors reached maturity and were fertile. The Ahr-/- mice showed decreased accumulation of lymphocytes in the spleen and lymph nodes, but not in the thymus. The livers of Ahr-/- mice were reduced in size by 50 percent and showed bile duct fibrosis Ahr-/- mice were also nonresponsive with regard to dioxin-mediated induction of genes encoding enzymes that catalyze the metabolism of foreign compounds. Thus, the AHR plays an important role in the development of the liver and the immune system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fernandez-Salguero, P -- Pineau, T -- Hilbert, D M -- McPhail, T -- Lee, S S -- Kimura, S -- Nebert, D W -- Rudikoff, S -- Ward, J M -- Gonzalez, F J -- P30 ES06096/ES/NIEHS NIH HHS/ -- R01 ES06811/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1995 May 5;268(5211):722-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Carcinogenesis, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7732381" target="_blank"〉PubMed〈/a〉

    Requirement of serine phosphorylation for formation of STAT-promoter complexes (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-03-31
    Beschreibung: Members of the interleukin-6 family of cytokines bind to and activate receptors that contain a common subunit, gp130. This leads to the activation of Stat3 and Stat1, two cytoplasmic signal transducers and activators of transcription (STATs), by tyrosine phosphorylation. Serine phosphorylation of Stat3 was constitutive and was enhanced by signaling through gp130. In cells of lymphoid and neuronal origins, inhibition of serine phosphorylation prevented the formation of complexes of DNA with Stat3-Stat3 but not with Stat3-Stat1 or Stat1-Stat1 dimers. In vitro serine dephosphorylation of Stat3 also inhibited DNA binding of Stat3-Stat3. The requirement of serine phosphorylation for Stat3-Stat3.DNA complex formation was inversely correlated with the affinity of Stat3-Stat3 for the binding site. Thus, serine phosphorylation appears to enhance or to be required for the formation of stable Stat3-Stat3.DNA complexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, X -- Blenis, J -- Li, H C -- Schindler, C -- Chen-Kiang, S -- CA46595/CA/NCI NIH HHS/ -- HL 21006/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 Mar 31;267(5206):1990-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brookdale Center for Molecular Biology, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7701321" target="_blank"〉PubMed〈/a〉

    Genetic feminization of brain structures and changed sexual orientation in male Drosophila (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-02-10
    Beschreibung: The neural basis of sexual orientation in Drosophila was studied by the production of males with regionally feminized brains. Such flies express the female form of the sex determination gene transformer in a limited number of neurons under the control of GAL4 enhancer trap inserts. This method facilitated the creation of lines with a stable pattern of feminization. In tests of sexual preferences, flies that were feminized in a portion of the antennal lobes or in a subset of the corpora pedunculata (mushroom bodies) courted both males and females. These two brain structures, both of which are involved in olfactory processing, may function in the recognition of sex-specific pheromones, in the control of sex-specific behaviors, or both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferveur, J F -- Stortkuhl, K F -- Stocker, R F -- Greenspan, R J -- New York, N.Y. -- Science. 1995 Feb 10;267(5199):902-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, New York University, NY 10003.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7846534" target="_blank"〉PubMed〈/a〉

    Cytostatic gene therapy for vascular proliferative disorders with a constitutively active form of the retinoblastoma gene product (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-27
    Beschreibung: Vascular smooth muscle cell (SMC) proliferation in response to injury is an important etiologic factor in vascular proliferative disorders such as atherosclerosis and restenosis after balloon angioplasty. The retinoblastoma gene product (Rb) is present in the unphosphorylated and active form in quiescent primary arterial SMCs, but is rapidly inactivated by phosphorylation in response to growth factor stimulation in vitro. A replication-defective adenovirus encoding a nonphosphorylatable, constitutively active form of Rb was constructed. Infection of cultured primary rat aortic SMCs with this virus inhibited growth factor-stimulated cell proliferation in vitro. Localized arterial infection with the virus at the time of balloon angioplasty significantly reduced SMC proliferation and neointima formation in both the rat carotid and porcine femoral artery models of restenosis. These results demonstrate the role of Rb in regulating vascular SMC proliferation and suggest a gene therapy approach for vascular proliferative disorders associated with arterial injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, M W -- Barr, E -- Seltzer, J -- Jiang, Y Q -- Nabel, G J -- Nabel, E G -- Parmacek, M S -- Leiden, J M -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):518-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7824950" target="_blank"〉PubMed〈/a〉

    Ethylene insensitivity conferred by Arabidopsis ERS gene (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-09-22
    Beschreibung: ERS (ethylene response sensor), a gene in the Arabidopsis thaliana ethylene hormone-response pathway, was uncovered by cross-hybridization with the Arabidopsis ETR1 gene. The deduced ERS protein has sequence similarity with the amino-terminal domain and putative histidine protein kinase domain of ETR1, but it does not have a receiver domain as found in ETR1. A missense mutation identical to the dominant etr1-4 mutation was introduced into the ERS gene. The altered ERS gene conferred dominant ethylene insensitivity to wild-type Arabidopsis. Double-mutant analysis indicates that ERS acts upstream of the CTR1 protein kinase gene in the ethylene-response pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hua, J -- Chang, C -- Sun, Q -- Meyerowitz, E M -- New York, N.Y. -- Science. 1995 Sep 22;269(5231):1712-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569898" target="_blank"〉PubMed〈/a〉

    Solution structure of a cisplatin-induced DNA interstrand cross-link (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-12-15
    Beschreibung: The widely used antitumor drug cis-diamminedichloroplatinum(II) (cisplatin or cis-DDP) reacts with DNA, cross-linking two purine residues through the N7 atoms, which reside in the major groove in B-form DNA. The solution structure of the short duplex [d(CAT-AGCTATG)]2 cross-linked at the GC:GC site was determined by nuclear magnetic resonance (NMR). The deoxyguanosine-bridging cis-diammineplatinum(II) lies in the minor groove, and the complementary deoxycytidines are extrahelical. The double helix is locally reversed to a left-handed form, and the helix is unwound and bent toward the minor groove. These findings were independently confirmed by results from a phase-sensitive gel electrophoresis bending assay. The NMR structure differs markedly from previously proposed models but accounts for the chemical reactivity, the unwinding, and the bending of cis-DDP interstrand cross-linked DNA and may be important in the formation and repair of these cross-links in chromatin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, H -- Zhu, L -- Reid, B R -- Drobny, G P -- Hopkins, P B -- GM32681/GM/NIGMS NIH HHS/ -- GM45804/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1842-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Washington, Seattle 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525382" target="_blank"〉PubMed〈/a〉

    Measurement of lactose repressor-mediated loop formation and breakdown in single DNA molecules (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-20
    Beschreibung: In gene regulatory systems in which proteins bind to multiple sites on a DNA molecule, the characterization of chemical mechanisms and single-step reaction rates is difficult because many chemical species may exist simultaneously in a molecular ensemble. This problem was circumvented by detecting DNA looping by the lactose repressor protein of Escherichia coli in single DNA molecules. The looping was detected by monitoring the nanometer-scale Brownian motion of microscopic particles linked to the ends of individual DNA molecules. This allowed the determination of the rates of formation and breakdown of a protein-mediated DNA loop in vitro. The measurements reveal that mechanical strain stored in the loop does not substantially accelerate loop breakdown, and the measurements also show that subunit dissociation of tetrameric repressor is not the predominant loop breakdown pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finzi, L -- Gelles, J -- New York, N.Y. -- Science. 1995 Jan 20;267(5196):378-80.〈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/7824935" target="_blank"〉PubMed〈/a〉

    Control of cell fate by a deubiquitinating enzyme encoded by the fat facets gene (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-12-15
    Beschreibung: Ubiquitin is a highly conserved polypeptide found in all eukaryotes. The major function of ubiquitin is to target proteins for complete or partial degradation by a multisubunit protein complex called the proteasome. Here, the Drosophila fat facets gene, which is required for the appropriate determination of particular cells in the fly eye, was shown to encode a ubiquitin-specific protease (Ubp), an enzyme that cleaves ubiquitin from ubiquitin-protein conjugates. The Fat facets protein (FAF) acts as a regulatory Ubp that prevents degradation of its substrate by the proteasome. Flies bearing fat facets gene mutations were used to show that a Ubp is cell type--and substrate-specific and a regulator of cell fate decisions in a multicellular organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Y -- Baker, R T -- Fischer-Vize, J A -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1828-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Texas, Austin 78712, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525378" target="_blank"〉PubMed〈/a〉

    Mutations of keratinocyte transglutaminase in lamellar ichthyosis (1995)

    Details
    Publikationsdatum: 1995-01-27
    Beschreibung: Lamellar ichthyosis is a severe congenital skin disorder characterized by generalized large scales and variable redness. Affected individuals in three families exhibited drastically reduced keratinocyte transglutaminase (TGK) activity. In two of these families, expression of TGK transcripts was diminished or abnormal and no TGK protein was detected. Homozygous or compound heterozygous mutations of the TGK gene were identified in all families. These data suggest that defects in TGK cause lamellar ichthyosis and that intact cross-linkage of cornified cell envelopes is required for epidermal tissue homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huber, M -- Rettler, I -- Bernasconi, K -- Frenk, E -- Lavrijsen, S P -- Ponec, M -- Bon, A -- Lautenschlager, S -- Schorderet, D F -- Hohl, D -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):525-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, Centre Hospitalier Universitaire Vandois (CHUV), Hopital de Beaumont, Lausanne, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7824952" target="_blank"〉PubMed〈/a〉

    The white gene of Ceratitis capitata: a phenotypic marker for germline transformation (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-12-22
    Beschreibung: Reliable germline transformation is required for molecular studies and ultimately for genetic control of economically important insects, such as the Mediterranean fruit fly (medfly) Ceratitis capitata. A prerequisite for the establishment and maintenance of transformant lines is selectable or phenotypically dominant markers. To this end, a complementary DNA clone derived from the medfly white gene was isolated, which showed substantial similarity to white genes in Drosophila melanogaster and other Diptera. It is correlated with a spontaneous mutation causing white eyes in the medfly and can be used to restore partial eye color in transgenic Drosophila carrying a null mutation in the endogenous white gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zwiebel, L J -- Saccone, G -- Zacharopoulou, A -- Besansky, N J -- Favia, G -- Collins, F H -- Louis, C -- Kafatos, F C -- New York, N.Y. -- Science. 1995 Dec 22;270(5244):2005-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Molecular Biology Laboratory (EMBL), Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8533095" target="_blank"〉PubMed〈/a〉

    Minor groove recognition of the conserved G.U pair at the Tetrahymena ribozyme reaction site (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-02-03
    Beschreibung: The guanine-uracil (G.U) base pair that helps to define the 5'-splice site of group I introns is phylogenetically highly conserved. In such a wobble base pair, G makes two hydrogen bonds with U in a geometry shifted from that of a canonical Watson-Crick pair. The contribution made by individual functional groups of the G.U pair in the context of the Tetrahymena ribozyme was examined by replacement of the G.U pair with synthetic base pairs that maintain a wobble configuration, but that systematically alter functional groups in the major and minor grooves of the duplex. The substitutions demonstrate that the exocyclic amine of G, when presented on the minor groove surface by the wobble base pair conformation, contributes substantially (2 kilocalories.mole-1) to binding by making a tertiary interaction with the ribozyme active site. It contributes additionally to transition state stabilization. The ribozyme active site also makes tertiary contacts with a tripod of 2'-hydroxyls on the minor groove surface of the splice site helix. This suggests that the ribozyme binds the duplex primarily in the minor groove. The alanyl aminoacyl transfer RNA (tRNA) synthetase recognizes the exocyclic amine of an invariant G.U pair and contacts a similar array of 2'-hydroxyls when binding the tRNA(Ala) acceptor stem, providing an unanticipated parallel between protein-RNA and RNA-RNA interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strobel, S A -- Cech, T R -- New York, N.Y. -- Science. 1995 Feb 3;267(5198):675-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Chemistry and Biochemistry, University of Colorado, Boulder 80309-0215.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7839142" target="_blank"〉PubMed〈/a〉

    Scope of the AIDS epidemic in the United States (1995)

    Publikationsdatum: 1995-11-24
    Beschreibung: Two-dimensional deconvolution techniques are used here to reconstruct age-specific human immunodeficiency virus (HIV) infection rates in the United States from surveillance data on acquired immunodeficiency syndrome (AIDS). This approach suggests that 630,000 to 897,000 adults and adolescents in the United States were living with HIV infection as of January 1993, including 107,000 to 150,000 women. The estimated incidence of HIV infection declined markedly over time among white males, especially those older than 30 years. In contrast, HIV incidence appears to have remained relatively constant among women and minorities. As of January 1993, prevalence was highest among young adults in their late twenties and thirties and among minorities. An estimated 3 percent of black men and 1 percent of black women in their thirties were living with HIV infection as of that date. If infection rates remain at these levels, HIV must be considered as endemic in the United States.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenberg, P S -- New York, N.Y. -- Science. 1995 Nov 24;270(5240):1372-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Cancer Institute, Rockville, MD 20852-4910, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481828" target="_blank"〉PubMed〈/a〉

    Mechanisms of rhodopsin inactivation in vivo as revealed by a COOH-terminal truncation mutant (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-20
    Beschreibung: Although biochemical experiments suggest that rhodopsin and other receptors coupled to heterotrimeric guanosine triphosphate-binding proteins (G proteins) are inactivated by phosphorylation near the carboxyl (COOH)-terminus and the subsequent binding of a capping protein, little is known about the quenching process in vivo. Flash responses were recorded from rods of transgenic mice in which a fraction of the rhodopsin molecules lacked the COOH-terminal phosphorylation sites. In the single photon regime, abnormally prolonged responses, attributed to activation of individual truncated rhodopsins, occurred interspersed with normal responses. The occurrence of the prolonged responses suggests that phosphorylation is required for normal shutoff. Comparison of normal and prolonged single photon responses indicated that rhodopsin begins to be quenched before the peak of the electrical response and that quenching limits the response amplitude.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, J -- Makino, C L -- Peachey, N S -- Baylor, D A -- Simon, M I -- AG12288/AG/NIA NIH HHS/ -- EY0570/EY/NEI NIH HHS/ -- F32 EY06405/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 20;267(5196):374-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena, CA 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7824934" target="_blank"〉PubMed〈/a〉

    Aberrant subcellular localization of BRCA1 in breast cancer (1995)
    American Association for the Advancement of Science (AAAS)

    Publikationsdatum: 1995-11-03
    Beschreibung: The BRCA1 gene product was identified as a 220-kilodalton nuclear phosphoprotein in normal cells, including breast ductal epithelial cells, and in 18 of 20 tumor cell lines derived from tissues other than breast and ovary. In 16 of 17 breast and ovarian cancer lines and 17 of 17 samples of cells obtained from malignant effusions, however, BRCA1 localized mainly in cytoplasm. Absence of BRCA1 or aberrant subcellular location was also observed to a variable extent in histological sections of many breast cancer biopsies. These findings suggest that BRCA1 abnormalities may be involved in the pathogenesis of many breast cancers, sporadic as well as familial.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Y -- Chen, C F -- Riley, D J -- Allred, D C -- Chen, P L -- Von Hoff, D -- Osborne, C K -- Lee, W H -- CA58318/CA/NCI NIH HHS/ -- EY05758/EY/NEI NIH HHS/ -- P50CA58183/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 3;270(5237):789-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular Medicine/Institute of Biotechnology, University of Texas Health Science Center at San Antonio 78245, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481765" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1995-09-08
    Beschreibung: Psychological traits are commonly inferred from covariation in sets of behavioral measures that otherwise appear to have little in common. Emotionality in mice is such a trait, defined here by covariation in activity and defecation in a novel environment and emergence into the open arms of an elevated plus maze. Behavioral and quantitative trait analyses were conducted on four measures obtained from 879 mice from an F2 intercross. Three loci, on murine chromosomes 1, 12, and 15, were mapped that influence emotionality. This trait, inferred from studies of strain, sex, and individual differences in rodents, may be related to human susceptibility to anxiety or neuroticism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flint, J -- Corley, R -- DeFries, J C -- Fulker, D W -- Gray, J A -- Miller, S -- Collins, A C -- DA-00197/DA/NIDA NIH HHS/ -- DA-05131/DA/NIDA NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1995 Sep 8;269(5229):1432-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Medicine, John Radcliffe Hospital, Oxford, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7660127" target="_blank"〉PubMed〈/a〉

    A role for CD5 in TCR-mediated signal transduction and thymocyte selection (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-28
    Beschreibung: CD5 is a transmembrane protein that is expressed on the surface of T cells and a subset of B cells. The absence of CD5 rendered thymocytes hyperresponsive to stimulation through the T cell antigen receptor (TCR) in vitro.

    Glutamate receptor RNA editing in vitro by enzymatic conversion of adenosine to inosine (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-03-10
    Beschreibung: RNA encoding the B subunit of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) subtype of ionotropic glutamate receptor (GluR-B) undergoes a posttranscriptional modification in which a genomically encoded adenosine is represented as a guanosine in the GluR-B complementary DNA. In vitro editing of GluR-B RNA transcripts with HeLa cell nuclear extracts was found to result from an activity that converts adenosine to inosine in regions of double-stranded RNA by enzymatic base modification. This activity is consistent with that of a double-stranded RNA-specific adenosine deaminase previously described in Xenopus oocytes and widely distributed in mammalian tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rueter, S M -- Burns, C M -- Coode, S A -- Mookherjee, P -- Emeson, R B -- ES00267/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1995 Mar 10;267(5203):1491-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Vanderbilt University School of Medicine, Nashville, TN 37232-6600.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7878468" target="_blank"〉PubMed〈/a〉

    Cloning of an intrinsic human TFIID subunit that interacts with multiple transcriptional activators (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-27
    Beschreibung: TFIID is a multisubunit protein complex comprised of the TATA-binding protein (TBP) and multiple TBP-associated factors (TAFs). The TAFs in TFIID are essential for activator-dependent transcription. The cloning of a complementary DNA encoding a human TFIID TAF, TAFII55, that has no known homolog in Drosophila TFIID is now described. TAFII55 is shown to interact with the largest subunit (TAFII230) of human TFIID through its central region and with multiple activators--including Sp1, YY1, USF, CTF, adenoviral E1A, and human immunodeficiency virus-type 1 Tat proteins--through a distinct amino-terminal domain. The TAFII55-interacting region of Sp1 was localized to its DNA-binding domain, which is distinct from the glutamine-rich activation domains previously shown to interact with Drosophila TAFII110. Thus, this human TFIID TAF may be a co-activator that mediates a response to multiple activators through a distinct mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chiang, C M -- Roeder, R G -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):531-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Biochemistry and 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/7824954" target="_blank"〉PubMed〈/a〉

    Reconstitution of IKATP: an inward rectifier subunit plus the sulfonylurea receptor (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-11-17
    Beschreibung: A member of the inwardly rectifying potassium channel family was cloned here. The channel, called BIR (Kir6.2), was expressed in large amounts in rat pancreatic islets and glucose-responsive insulin-secreting cell lines. Coexpression with the sulfonylurea receptor SUR reconstituted an inwardly rectifying potassium conductance of 76 picosiemens that was sensitive to adenosine triphosphate (ATP) (IKATP) and was inhibited by sulfonylureas and activated by diazoxide. The data indicate that these pancreatic beta cell potassium channels are a complex composed of at least two subunits--BIR, a member of the inward rectifier potassium channel family, and SUR, a member of the ATP-binding cassette superfamily. Gene mapping data show that these two potassium channel subunit genes are clustered on human chromosome 11 at position 11p15.1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Inagaki, N -- Gonoi, T -- Clement, J P 4th -- Namba, N -- Inazawa, J -- Gonzalez, G -- Aguilar-Bryan, L -- Seino, S -- Bryan, J -- DK44311/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 17;270(5239):1166-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Medicine, Chiba University School of Medicine, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502040" target="_blank"〉PubMed〈/a〉

    Induction of MHC class I genes in neurons (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-28
    Beschreibung: Whether neurons express major histocompatibility complex (MHC) class I genes has not been firmly established. The techniques of confocal laser microscopy, patch clamp electrophysiology, and reverse transcriptase-polymerase chain reaction were combined here to directly examine the inducibility of MHC class I genes in individual cultured rat hippocampal neurons. Transcription of MHC class I genes was very rare in neurons with spontaneous action potentials. In electrically silent neurons, transcription was noted, with expression of beta 2-microglobulin under tighter control than in class I heavy chain molecules. Surface expression of class I molecules occurred only in electrically silent neurons treated with interferon gamma. Immunosurveillance by cytotoxic T cells may be focused on functionally impaired neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neumann, H -- Cavalie, A -- Jenne, D E -- Wekerle, H -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):549-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroimmunology, Max Planck Institute for Psychiatry, Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624779" target="_blank"〉PubMed〈/a〉

    Selective opioid inhibition of small nociceptive neurons (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-11-24
    Beschreibung: Opioid analgesia, the selective suppression of pain without effects on other sensations, also distinguishes between different types of pain: severe, persistent pain is potently inhibited by opioids, but they fail to cohceal the sensation of a pinprick. The cellular basis for this specificity was analyzed by means of patch-clamp experiments performed on fluorescently labeled nociceptive neurons (nociceptors) that innervate rat tooth pulp. Activation of the mu opioid receptor inhibited calcium channels on almost all small nociceptors but had minimal effect on large nociceptors. Somatostatin had the opposite specificity, preferentially inhibiting calcium channels on the large cells. Because persistent pain is mediated by slow-conducting, small nociceptors, opioids are thus likely to inhibit neurotransmitter release only at those primary synapses specialized for persistent pain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taddese, A -- Nah, S Y -- McCleskey, E W -- New York, N.Y. -- Science. 1995 Nov 24;270(5240):1366-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland 97201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481826" target="_blank"〉PubMed〈/a〉

    Beschreibung: A morbillivirus has been isolated and added to an increasing list of emerging viral diseases. This virus caused an outbreak of fatal respiratory disease in horses and humans. Genetic analyses show it to be only distantly related to the classic morbilliviruses rinderpest, measles, and canine distemper. When seen by electron microscopy, viruses had 10- and 18-nanometer surface projections that gave them a "double-fringed" appearance. The virus induced syncytia that developed in the endothelium of blood vessels, particularly the lungs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murray, K -- Selleck, P -- Hooper, P -- Hyatt, A -- Gould, A -- Gleeson, L -- Westbury, H -- Hiley, L -- Selvey, L -- Rodwell, B -- New York, N.Y. -- Science. 1995 Apr 7;268(5207):94-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CSIRO Australian Animal Health Laboratory, East Geelong, Victoria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7701348" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1995-10-27
    Beschreibung: During pregnancy a semiallogeneic fetus survives despite the presence of maternal T cells specific for paternally inherited histocompatibility antigens. A mouse transgenic for a T cell receptor recognizing the major histocompatibility (MHC) antigen H-2Kb was used to follow the fate of T cells reactive to paternal alloantigens. In contrast to syngeneic and third-party allogeneic pregnancies, mice bearing a Kb-positive conceptus had reduced numbers of Kb-reactive T cells and accepted Kb-positive tumor grafts. T cell phenotype and responsiveness were restored after delivery. Thus, during pregnancy maternal T cells acquire a transient state of tolerance specific for paternal alloantigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tafuri, A -- Alferink, J -- Moller, P -- Hammerling, G J -- Arnold, B -- New York, N.Y. -- Science. 1995 Oct 27;270(5236):630-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tumor Immunology Program, Deutsches Krebsforschungszentrum (DKFZ), Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7570020" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1995-02-10
    Beschreibung: Infection of cattle with the protozoan parasite Theileria parva results in a fatal lymphoproliferative syndrome that is associated with the overexpression of casein kinase II. The role of this enzyme in the pathogenesis of lymphoproliferative disorders was investigated by expressing the catalytic subunit in lymphocytes of transgenic mice. Adult transgenic mice displayed a stochastic propensity to develop lymphoma; co-expression of a c-myc transgene in addition to casein kinase II resulted in neonatal leukemia. Thus, the casein kinase II gene can serve as an oncogene, and its dysregulated expression is capable of transforming lymphocytes in a two-step pathway with c-myc.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seldin, D C -- Leder, P -- 1-K08-HL0286-01/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 Feb 10;267(5199):894-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Howard Hughes Medical Institute, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7846532" target="_blank"〉PubMed〈/a〉

    Serial analysis of gene expression (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-10-20
    Beschreibung: The characteristics of an organism are determined by the genes expressed within it. A method was developed, called serial analysis of gene expression (SAGE), that allows the quantitative and simultaneous analysis of a large number of transcripts. To demonstrate this strategy, short diagnostic sequence tags were isolated from pancreas, concatenated, and cloned. Manual sequencing of 1000 tags revealed a gene expression pattern characteristic of pancreatic function. New pancreatic transcripts corresponding to novel tags were identified. SAGE should provide a broadly applicable means for the quantitative cataloging and comparison of expressed genes in a variety of normal, developmental, and disease states.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Velculescu, V E -- Zhang, L -- Vogelstein, B -- Kinzler, K W -- CA35494/CA/NCI NIH HHS/ -- CA57345/CA/NCI NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Oct 20;270(5235):484-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oncology Center, Johns Hopkins University, Baltimore, MD 21231, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7570003" target="_blank"〉PubMed〈/a〉

    Structure of the Arabidopsis RPM1 gene enabling dual specificity disease resistance (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-08-11
    Beschreibung: Plants can recognize pathogens through the action of disease resistance (R) genes, which confer resistance to pathogens expressing unique corresponding avirulence (avr) genes. The molecular basis of this gene-for-gene specificity is unknown. The Arabidopsis thaliana RPM1 gene enables dual specificity to pathogens expressing either of two unrelated Pseudomonas syringae avr genes. Despite this function, RPM1 encodes a protein sharing molecular features with recently described single-specificity R genes. Surprisingly, RPM1 is lacking from naturally occurring, disease-susceptible Arabidopsis accessions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grant, M R -- Godiard, L -- Straube, E -- Ashfield, T -- Lewald, J -- Sattler, A -- Innes, R W -- Dangl, J L -- R29 GM 46451/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Aug 11;269(5225):843-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Delbruck Laboratory, Koln, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7638602" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1995-01-06
    Beschreibung: Hematopoietic cells differentiate in steps marked by the acquisition or loss of specific phenotypic characteristics. Human bone marrow cells that were responsive to the early-acting cytokines Kit ligand and interleukin-3 were forced to a metabolic death. The subfraction remaining represented 1 in 10(5) bone marrow mononuclear cells, were determined to be quiescent by cell cycle analysis, and had a stem cell immunophenotype. The cells were highly enriched for long-term culture-initiating cells, were capable of secondary colony formation, and produced both myeloid and lymphoid progeny. Thus, this technically simple strategy led to the efficient purification of cells with characteristics of hematopoietic stem cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berardi, A C -- Wang, A -- Levine, J D -- Lopez, P -- Scadden, D T -- R01-HL44851/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 6;267(5194):104-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology/Oncology, Deaconess Hospital, Harvard Medical School, Boston, MA 02215.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7528940" target="_blank"〉PubMed〈/a〉

    Molecular basis of the cauliflower phenotype in Arabidopsis (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-27
    Beschreibung: Genetic studies demonstrate that two Arabidopsis genes, CAULIFLOWER and APETALA1, encode partially redundant activities involved in the formation of floral meristems, the first step in the development of flowers. Isolation of the CAULIFLOWER gene from Arabidopsis reveals that it is closely related in sequence to APETALA1. Like APETALA1, CAULIFLOWER is expressed in young flower primordia and encodes a MADS-domain, indicating that it may function as a transcription factor. Analysis of the cultivated garden variety of cauliflower (Brassica oleracea var. botrytis) reveals that its CAULIFLOWER gene homolog is not functional, suggesting a molecular basis for one of the oldest recognized flower abnormalities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kempin, S A -- Savidge, B -- Yanofsky, M F -- GM07313/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):522-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, San Diego, La Jolla 92093-0116.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7824951" target="_blank"〉PubMed〈/a〉

    Gene therapy in peripheral blood lymphocytes and bone marrow for ADA- immunodeficient patients (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-10-20
    Beschreibung: Adenosine deaminase (ADA) deficiency results in severe combined immunodeficiency, the first genetic disorder treated by gene therapy. Two different retroviral vectors were used to transfer ex vivo the human ADA minigene into bone marrow cells and peripheral blood lymphocytes from two patients undergoing exogenous enzyme replacement therapy. After 2 years of treatment, long-term survival of T and B lymphocytes, marrow cells, and granulocytes expressing the transferred ADA gene was demonstrated and resulted in normalization of the immune repertoire and restoration of cellular and humoral immunity. After discontinuation of treatment, T lymphocytes, derived from transduced peripheral blood lymphocytes, were progressively replaced by marrow-derived T cells in both patients. These results indicate successful gene transfer into long-lasting progenitor cells, producing a functional multilineage progeny.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bordignon, C -- Notarangelo, L D -- Nobili, N -- Ferrari, G -- Casorati, G -- Panina, P -- Mazzolari, E -- Maggioni, D -- Rossi, C -- Servida, P -- Ugazio, A G -- Mavilio, F -- B.36/Telethon/Italy -- New York, N.Y. -- Science. 1995 Oct 20;270(5235):470-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Telethon Gene Therapy Program for Genetic Diseases, DIBIT, Istituto Scientifico H.

    KAI1, a metastasis suppressor gene for prostate cancer on human chromosome 11p11.2 (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-05-12
    Beschreibung: A gene from human chromosome 11p11.2 was isolated and was shown to suppress metastasis when introduced into rat AT6.1 prostate cancer cells. Expression of this gene, designated KAI1, was reduced in human cell lines derived from metastatic prostate tumors. KAI1 specifies a protein of 267 amino acids, with four hydrophobic and presumably transmembrane domains and one large extracellular hydrophilic domain with three potential N-glycosylation sites. KAI1 is evolutionarily conserved, is expressed in many human tissues, and encodes a member of a structurally distinct family of leukocyte surface glycoproteins. Decreased expression of this gene may be involved in the malignant progression of prostate and other cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dong, J T -- Lamb, P W -- Rinker-Schaeffer, C W -- Vukanovic, J -- Ichikawa, T -- Isaacs, J T -- Barrett, J C -- CA 58236/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 May 12;268(5212):884-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Carcinogenesis, National Institute of Environmental Health Sciences, National Institute of Health, Research Triangle Park, NC 27709, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754374" target="_blank"〉PubMed〈/a〉

    A VAMP-binding protein from Aplysia required for neurotransmitter release (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-09-15
    Beschreibung: Before the fusion of synaptic vesicles with the plasma membrane, a protein complex is thought to form between VAMP--an integral membrane protein of the vesicle--and two proteins associated with the plasma membrane, SNAP-25 and syntaxin. The yeast two-hybrid interaction cloning system has now been used to identify additional proteins from Aplysia that interact directly with VAMP. A 33-kilodalton membrane protein, termed VAP-33 (VAMP-associated protein of 33 kilodaltons), was identified whose corresponding messenger RNA was detected only in the central nervous system and the gill of Aplysia. Presynaptic injection of antibodies specific for VAP-33 inhibited synaptic transmission, which suggests that VAP-33 is required for the exocytosis of neurotransmitter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Skehel, P A -- Martin, K C -- Kandel, E R -- Bartsch, D -- R37 MH45923-06/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 15;269(5230):1580-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, College of Physicians and Surgeons of Columbia University, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7667638" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1995-05-12
    Beschreibung: Gene trap transposon mutagenesis can identify essential genes whose functions in later development are obscured by an early lethal phenotype. In higher plants, many genes are required for haploid gametophyte viability, so that the phenotypic effects of their disruption cannot be readily observed in the diploid plant body. The PROLIFERA (PRL) gene, identified by gene trap transposon mutagenesis in Arabidopsis, is required for megaga-metophyte and embryo development. Reporter gene expression patterns revealed that PRL was expressed in dividing cells throughout the plant. PRL is related to the MCM2-3-5 family of yeast genes that are required for the initiation of DNA replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Springer, P S -- McCombie, W R -- Sundaresan, V -- Martienssen, R A -- New York, N.Y. -- Science. 1995 May 12;268(5212):877-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, NY 11724, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754372" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1995-07-07
    Beschreibung: Peptide synthetases involved in the nonribosomal synthesis of peptide secondary metabolites possess a highly conserved domain structure. The arrangement of these domains within the multifunctional enzymes determines the number and order of the amino acid constituents of the peptide product. A general approach has been developed for targeted substitution of amino acid-activating domains within the srfA operon, which encodes the protein templates for the synthesis of the lipopeptide antibiotic surfactin in Bacillus subtilis. Exchange of domain-coding regions of bacterial and fungal origin led to the construction of hybrid genes that encoded peptide synthetases with altered amino acid specificities and the production of peptides with modified amino acid sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stachelhaus, T -- Schneider, A -- Marahiel, M A -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):69-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biochemie/Fachbereich Chemie, Philipps-University of Marburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7604280" target="_blank"〉PubMed〈/a〉

    A regulatory role for ARF6 in receptor-mediated endocytosis (1995)

    Details
    Publikationsdatum: 1995-02-24
    Beschreibung: Adenosine diphosphate-ribosylation factor 6 (ARF6), ARF6 mutants, and ARF1 were transiently expressed in Chinese hamster ovary cells, and the effects on receptor-mediated endocytosis were assessed. Overexpressed ARF6 localized to the cell periphery and led to a redistribution of transferrin receptors to the cell surface and a decrease in the rate of uptake of transferrin. Similar results were obtained when a mutant defective in guanosine triphosphate hydrolysis was expressed. Expression of a dominant negative mutant, ARF6(T27N), resulted in an intracellular distribution of transferrin receptors and an inhibition of transferrin recycling to the cell surface. In contrast, overexpression of ARF1 had little or no effect on these parameters of endocytosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉D'Souza-Schorey, C -- Li, G -- Colombo, M I -- Stahl, P D -- New York, N.Y. -- Science. 1995 Feb 24;267(5201):1175-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology and Physiology, 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/7855600" target="_blank"〉PubMed〈/a〉

    Nicotine enhancement of fast excitatory synaptic transmission in CNS by presynaptic receptors (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-09-22
    Beschreibung: The behavioral and cognitive effects of nicotine suggest that nicotinic acetylcholine receptors (nAChRs) participate in central nervous system (CNS) function. Although nAChR subunit messenger RNA (mRNA) and nicotine binding sites are common in the brain, there is little evidence for synapses mediated by nAChRs in the CNS. To test whether, CNS nAChRs might modify rather than mediate transmission, the regulation of excitatory synaptic transmission by these receptors was examined. Nanomolar concentrations of nicotine enhanced both glutamatergic and cholinergic synaptic transmission by activation of presynaptic nAChRs that increased presynaptic [Ca2]i. Pharmacological and subunit deletion experiments reveal that these presynaptic nAChRs include the alpha 7 subunit. These findings reveal that CNS nAChRs enhance fast excitatory transmission, providing a likely mechanism for the complex behavioral effects of nicotine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGehee, D S -- Heath, M J -- Gelber, S -- Devay, P -- Role, L W -- NS09395/NS/NINDS NIH HHS/ -- NS22061/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 22;269(5231):1692-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology and Anatomy, Columbia University, College of Physicians and Surgeons, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569895" target="_blank"〉PubMed〈/a〉

    Inducible gene targeting in mice (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-09-08
    Beschreibung: A method of gene targeting that allows the inducible inactivation of a target gene in mice is presented. The method uses an interferon-responsive promoter to control the expression of Cre recombinase. Here, Cre was used to delete a segment of the DNA polymerase beta gene flanked by IoxP recombinase recognition sites. Deletion was complete in liver and nearly complete in lymphocytes within a few days, whereas partial deletion was obtained in other tissues. This method can be used for the inducible inactivation of any other gene in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuhn, R -- Schwenk, F -- Aguet, M -- Rajewsky, K -- New York, N.Y. -- Science. 1995 Sep 8;269(5229):1427-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genetics, University of Cologne, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7660125" target="_blank"〉PubMed〈/a〉

    Antigen-specific development of primary and memory T cells in vivo (1995)

    Publikationsdatum: 1995-04-07
    Beschreibung: The expansion and contraction of specific helper T cells in the draining lymph nodes of normal mice after injection with antigen was followed. T cell receptors from purified primary and memory responder cells had highly restricted junctional regions, indicating antigen-driven selection. Selection for homogeneity in the length of the third complementarity-determining region (CDR3) occurs before selection for some of the characteristic amino acids, indicating the importance of this parameter in T cell receptor recognition. Ultimately, particular T cell receptor sequences come to predominate in the secondary response and others disappear, showing the selective preservation or expansion of specific T cell clones.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McHeyzer-Williams, M G -- Davis, M M -- New York, N.Y. -- Science. 1995 Apr 7;268(5207):106-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Stanford University School of Medicine, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7535476" target="_blank"〉PubMed〈/a〉

    A p16INK4a-insensitive CDK4 mutant targeted by cytolytic T lymphocytes in a human melanoma (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-09-01
    Beschreibung: A mutated cyclin-dependent kinase 4 (CDK4) was identified as a tumor-specific antigen recognized by HLA-A2. 1-restricted autologous cytolytic T lymphocytes (CTLs) in a human melanoma. The mutated CDK4 allele was present in autologous cultured melanoma cells and metastasis tissue, but not in the patient's lymphocytes. The mutation, an arginine-to-cysteine exchange at residue 24, was part of the CDK4 peptide recognized by CTLs and prevented binding of the CDK4 inhibitor p16INK4a, but not of p21 or of p27KIP1. The same mutation was found in one additional melanoma among 28 melanomas analyzed. These results suggest that mutation of CDK4 can create a tumor-specific antigen and can disrupt the cell-cycle regulation exerted by the tumor suppressor p16INK4a.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolfel, T -- Hauer, M -- Schneider, J -- Serrano, M -- Wolfel, C -- Klehmann-Hieb, E -- De Plaen, E -- Hankeln, T -- Meyer zum Buschenfelde, K H -- Beach, D -- New York, N.Y. -- Science. 1995 Sep 1;269(5228):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medizinische Klinik und Poliklinik, Johannes Gutenberg-Universitat, Mainz, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7652577" target="_blank"〉PubMed〈/a〉

    Beschreibung: A Pseudomonas aeruginosa strain (UCBPP-PA14) is infectious both in an Arabidopsis thaliana leaf infiltration model and in a mouse full-thickness skin burn model. UCBPP-PA14 exhibits ecotype specificity for Arabidopsis, causing a range of symptoms from none to severe in four different ecotypes. In the mouse model, UCBPP-PA14 is as lethal as other well-studied P. aeruginosa strains. Mutations in the UCBPP-PA14 toxA, plcS, and gacA genes resulted in a significant reduction in pathogenicity in both hosts, indicating that these genes encode virulence factors required for the full expression of pathogenicity in both plants and animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rahme, L G -- Stevens, E J -- Wolfort, S F -- Shao, J -- Tompkins, R G -- Ausubel, F M -- New York, N.Y. -- Science. 1995 Jun 30;268(5219):1899-902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7604262" target="_blank"〉PubMed〈/a〉

    Inactivation of the mouse Huntington's disease gene homolog Hdh (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-21
    Beschreibung: Huntington's disease (HD) is a dominant neurodegenerative disorder caused by expansion of a CAG repeat in the gene encoding huntingtin, a protein of unknown function. To distinguish between "loss of function" and "gain of function" models of HD, the murine HD homolog Hdh was inactivated by gene targeting. Mice heterozygous for Hdh inactivation were phenotypically normal, whereas homozygosity resulted in embryonic death. Homozygotes displayed abnormal gastrulation at embryonic day 7.5 and were resorbing by day 8.5. Thus, huntingtin is critical early in embryonic development, before the emergence of the nervous system. That Hdh inactivation does not mimic adult HD neuropathology suggests that the human disease involves a gain of function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duyao, M P -- Auerbach, A B -- Ryan, A -- Persichetti, F -- Barnes, G T -- McNeil, S M -- Ge, P -- Vonsattel, J P -- Gusella, J F -- Joyner, A L -- NS16367/NS/NINDS NIH HHS/ -- NS32765/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Jul 21;269(5222):407-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Neurogenetics Unit, Massachusetts General Hospital, Charlestown 02129, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7618107" target="_blank"〉PubMed〈/a〉

    Beschreibung: The goa-1 gene encoding the alpha subunit of the heterotrimeric guanosine triphosphate-binding protein (G protein) Go from Caenorhabditis elegans is expressed in most neurons, and in the muscles involved in egg laying and male mating. Reduction-of-function mutations in goa-1 caused a variety of behavioral defects including hyperactive movement, premature egg laying, and male impotence. Expression of the activated Go alpha subunit (G alpha o) in transgenic nematodes resulted in lethargic movement, delayed egg laying, and reduced mating efficiency. Induced expression of activated G alpha o in adults was sufficient to cause these phenotypes, indicating that G alpha o mediates behavior through its role in neuronal function and the functioning of specialized muscles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mendel, J E -- Korswagen, H C -- Liu, K S -- Hajdu-Cronin, Y M -- Simon, M I -- Plasterk, R H -- Sternberg, P W -- New York, N.Y. -- Science. 1995 Mar 17;267(5204):1652-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7886455" target="_blank"〉PubMed〈/a〉

    Domain interaction between NMDA receptor subunits and the postsynaptic density protein PSD-95 (1995)

    Details
    Publikationsdatum: 1995-09-22
    Beschreibung: The N-methyl-D-aspartate (NMDA) receptor subserves synaptic glutamate-induced transmission and plasticity in central neurons. The yeast two-hybrid system was used to show that the cytoplasmic tails of NMDA receptor subunits interact with a prominent postsynaptic density protein PSD-95. The second PDZ domain in PSD-95 binds to the seven-amino acid, COOH-terminal domain containing the terminal tSXV motif (where S is serine, X is any amino acid, and V is valine) common to NR2 subunits and certain NR1 splice forms. Transcripts encoding PSD-95 are expressed in a pattern similar to that of NMDA receptors, and the NR2B subunit co-localizes with PSD-95 in cultured rat hippocampal neurons. The interaction of these proteins may affect the plasticity of excitatory synapses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kornau, H C -- Schenker, L T -- Kennedy, M B -- Seeburg, P H -- NS-28710/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 22;269(5231):1737-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular Biology (ZMBH), University of Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569905" target="_blank"〉PubMed〈/a〉

In extracts from [URE3] strains, Ure2p was partially resistant to proteinase K compared with Ure2p from wild-type extracts. Overexpression of Ure2p in wild-type strains induced a 20- to 200-fold increase in the frequency with which [URE3] arose. Overexpression of just the amino-terminal 65 residues of Ure2p increased the frequency of [URE3] induction 6000-fold. Without this "prion-inducing domain" the carboxyl-terminal domain performed the nitrogen regulation function of Ure2p, but could not be changed to the [URE3] prion state. Thus, this domain induced the prion state in trans, whereas in cis it conferred susceptibility of the adjoining nitrogen regulatory domain to prion infections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masison, D C -- Wickner, R B -- New York, N.Y. -- Science. 1995 Oct 6;270(5233):93-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section on Genetics of Simple Eukaryotes, National Institute of Diabetes, Digestive and Kidney Disease, National Institutes of Health, Bethesda, MD 20892-0830, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569955" target="_blank"〉PubMed〈/a〉

    Rescue of the En-1 mutant phenotype by replacement of En-1 with En-2 (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-08-04
    Beschreibung: The related mouse Engrailed genes En-1 and En-2 are expressed from the one- and approximately five-somite stages, respectively, in a similar presumptive mid-hindbrain domain. However, mutations in En-1 and En-2 produce different phenotypes. En-1 mutant mice die at birth with a large mid-hindbrain deletion, whereas En-2 mutants are viable, with cerebellar defects. To determine whether these contrasting phenotypes reflect differences in temporal expression or biochemical activity of the En proteins, En-1 coding sequences were replaced with En-2 sequences by gene targeting. This rescued all En-1 mutant defects, demonstrating that the difference between En-1 and En-2 stems from their divergent expression patterns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanks, M -- Wurst, W -- Anson-Cartwright, L -- Auerbach, A B -- Joyner, A L -- New York, N.Y. -- Science. 1995 Aug 4;269(5224):679-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular and Developmental Biology, Samuel Lunenfeld Research Institute, Mt.

    Frequency and distribution of DNA uptake signal sequences in the Haemophilus influenzae Rd genome (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-28
    Beschreibung: The naturally transformable, Gram-negative bacterium Haemophilus influenzae Rd preferentially takes up DNA of its own species by recognizing a 9-base pair sequence, 5'-AAGTGCGGT, carried in multiple copies in its chromosome. With the availability of the complete genome sequence, 1465 copies of the 9-base pair uptake site have been identified. Alignment of these sites unexpectedly reveals an extended consensus region of 29 base pairs containing the core 9-base pair region and two downstream 6-base pair A/T-rich regions, each spaced about one helix turn apart. Seventeen percent of the sites are in inverted repeat pairs, many of which are located downstream to gene termini and are capable of forming stem-loop structures in messenger RNA that might function as signals for transcription termination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, H O -- Tomb, J F -- Dougherty, B A -- Fleischmann, R D -- Venter, J C -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):538-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Genetics, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7542802" target="_blank"〉PubMed〈/a〉

    Excision of deoxyribose phosphate residues by DNA polymerase beta during DNA repair (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-08-04
    Beschreibung: Eukaryotic DNA polymerase beta (pol beta) can catalyze DNA synthesis during base excision DNA repair. It is shown here that pol beta also catalyzes release of 5'-terminal deoxyribose phosphate (dRP) residues from incised apurinic-apyrimidinic sites, which are common intermediate products in base excision repair. The catalytic domain for this activity resides within an amino-terminal 8-kilodalton fragment of pol beta, which comprises a distinct structural domain of the enzyme. Magnesium is required for the release of dRP from double-stranded DNA but not from a single-stranded oligonucleotide. Analysis of the released products indicates that the excision reaction occurs by beta-elimination rather than hydrolysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsumoto, Y -- Kim, K -- CA06927/CA/NCI NIH HHS/ -- CA63154/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Aug 4;269(5224):699-702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiation Oncology, Fox Chase Cancer Center, Philadelphia, PA 19111, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624801" target="_blank"〉PubMed〈/a〉

    Structure-based design of transcription factors (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-01-06
    Beschreibung: Computer modeling suggested that transcription factors with novel sequence specificities could be designed by combining known DNA binding domains. This structure-based strategy was tested by construction of a fusion protein, ZFHD1, that contained zinc fingers 1 and 2 from Zif268, a short polypeptide linker, and the homeodomain from Oct-1. The fusion protein bound optimally to a sequence containing adjacent homeodomain (TAATTA) and zinc finger (NGGGNG) subsites. When fused to an activation domain, ZFHD1 regulated promoter activity in vivo in a sequence-specific manner. Analysis of known protein-DNA complexes suggests that many other DNA binding proteins could be designed in a similar fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pomerantz, J L -- Sharp, P A -- Pabo, C O -- P01-CA42063/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 6;267(5194):93-6.〈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/7809612" target="_blank"〉PubMed〈/a〉

    Tissue- and species-specific expression of sp56, a mouse sperm fertilization protein (1995)

    Beschreibung: Mouse sperm recognize and bind to ZP3, one of three glycoproteins in the egg's zona pellucida. A mouse sperm protein, sp56, was identified that has the characteristics expected of the sperm protein responsible for recognition of ZP3. The complementary DNA encoding sp56 was isolated, and its primary sequence indicates that sp56 is a member of a superfamily of protein receptors. It was shown that sp56 expression is restricted to mouse spermatids and that the presence or absence of sp56 on sperm from different species accounts for species specificity of sperm-egg recognition in mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bookbinder, L H -- Cheng, A -- Bleil, J D -- R01 HD 27847/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):86-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Research Institute, Department of Molecular Biology, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7604284" target="_blank"〉PubMed〈/a〉

    Association of the yeast pheromone response G protein beta gamma subunits with the MAP kinase scaffold Ste5p (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-09-15
    Beschreibung: The mating response pathway of the yeast Saccharomyces cerevisiae includes a heterotrimeric guanine nucleotide-binding protein (G protein) that activates a mitogen-activated protein MAP kinase cascade by an unknown mechanism. An amino-terminal fragment of the MAP kinase scaffold protein Ste5p that interfered with pheromone-induced cell cycle arrest was identified. A haploid-specific interaction between the amino terminus of Ste5p and the G protein beta subunit Ste4p was also detected in a two-hybrid assay, and the product of a signaling-defective allele of STE4 was defective in this interaction. In cells with a constitutively activated pheromone response pathway, epitope-tagged Ste4p was coimmunoprecipitated with Ste5p. Thus, association of the G protein and the MAP kinase cassette via the scaffolding protein Ste5p may transmit the G protein signal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whiteway, M S -- Wu, C -- Leeuw, T -- Clark, K -- Fourest-Lieuvin, A -- Thomas, D Y -- Leberer, E -- New York, N.Y. -- Science. 1995 Sep 15;269(5230):1572-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biotechnology Research Institute, National Research Council of Canada, Montreal, Quebec.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7667635" target="_blank"〉PubMed〈/a〉

    Beschreibung: An insertional mutagenesis system that uses transposons carrying unique DNA sequence tags was developed for the isolation of bacterial virulence genes. The tags from a mixed population of bacterial mutants representing the inoculum and bacteria recovered from infected hosts were detected by amplification, radiolabeling, and hybridization analysis. When applied to a murine model of typhoid fever caused by Salmonella typhimurium, mutants with attenuated virulence were revealed by use of tags that were present in the inoculum but not in bacteria recovered from infected mice. This approach resulted in the identification of new virulence genes, some of which are related to, but functionally distinct from, the inv/spa family of S. typhimurium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hensel, M -- Shea, J E -- Gleeson, C -- Jones, M D -- Dalton, E -- Holden, D W -- New York, N.Y. -- Science. 1995 Jul 21;269(5222):400-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Infectious Diseases and Bacteriology, Royal Postgraduate Medical School, Hammersmith Hospital, London, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7618105" target="_blank"〉PubMed〈/a〉

    Potential mechanism for sustained antiretroviral efficacy of AZT-3TC combination therapy (1995)

    Publikationsdatum: 1995-08-04
    Beschreibung: Combinations of antiretroviral drugs that prevent or delay the appearance of drug-resistant human immunodeficiency virus-type 1 (HIV-1) mutants are urgently required. Mutants resistant to 3'-azidothymidine (AZT, zidovudine) became phenotypically sensitive in vitro by mutation of residue 184 of viral reverse transcriptase to valine, which also induced resistance to (-)2'-deoxy-3'-thiacytidine (3TC). Furthermore, AZT-3TC coresistance was not observed during extensive in vitro selection with both drugs. In vivo AZT-3TC combination therapy resulted in a markedly greater decreased in serum HIV-1 RNA concentrations than treatment with AZT alone, even though valine-184 mutants rapidly emerged. Most samples assessed from the combination group remained AZT sensitive at 24 weeks of therapy, consistent with in vitro mutation studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Larder, B A -- Kemp, S D -- Harrigan, P R -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1995 Aug 4;269(5224):696-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Antiviral Therapeutic Research Unit, Wellcome Research Laboratories, Beckenham, Kent, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7542804" target="_blank"〉PubMed〈/a〉

    Beschreibung: Seven families of RNA ligases, previously isolated from random RNA sequences, fall into three classes on the basis of secondary structure and regiospecificity of ligation. Two of the three classes of ribozymes have been engineered to act as true enzymes, catalyzing the multiple-turnover transformation of substrates into products. The most complex of these ribozymes has a minimal catalytic domain of 93 nucleotides. An optimized version of this ribozyme has a kcat exceeding one per second, a value far greater than that of most natural RNA catalysts and approaching that of comparable protein enzymes. The fact that such a large and complex ligase emerged from a very limited sampling of sequence space implies the existence of a large number of distinct RNA structures of equivalent complexity and activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ekland, E H -- Szostak, J W -- Bartel, D P -- New York, N.Y. -- Science. 1995 Jul 21;269(5222):364-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7618102" target="_blank"〉PubMed〈/a〉

    Identification of a member of the MAPKKK family as a potential mediator of TGF-beta signal transduction (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-12-22
    Beschreibung: The mitogen-activated protein kinase (MAPK) pathway is a conserved eukaryotic signaling module that converts receptor signals into various outputs. MAPK is activated through phosphorylation by MAPK kinase (MAPKK), which is first activated by MAPKK kinase (MAPKKK). A genetic selection based on a MAPK pathway in yeast was used to identify a mouse protein kinase (TAK1) distinct from other members of the MAPKKK family. TAK1 was shown to participate in regulation of transcription by transforming growth factor-beta (TGF-beta). Furthermore, kinase activity of TAK1 was stimulated in response to TGF-beta and bone morphogenetic protein. These results suggest that TAK1 functions as a mediator in the signaling pathway of TGF-beta superfamily members.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamaguchi, K -- Shirakabe, K -- Shibuya, H -- Irie, K -- Oishi, I -- Ueno, N -- Taniguchi, T -- Nishida, E -- Matsumoto, K -- New York, N.Y. -- Science. 1995 Dec 22;270(5244):2008-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Faculty of Science, Nagoya University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8533096" target="_blank"〉PubMed〈/a〉

    Beschreibung: The recent positional cloning of the mouse ob gene and its human homology has provided the basis to investigate the potential role of the ob gene product in body weight regulation. A biologically active form of recombinant mouse OB protein was overexpressed and purified to near homogeneity from a bacterial expression system. Peripheral and central administration of microgram doses of OB protein reduced food intake and body weight of ob/ob and diet-induced obese mice but not in db/db obese mice.

    Revival and identification of bacterial spores in 25- to 40-million-year-old Dominican amber (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-05-19
    Beschreibung: A bacterial spore was revived, cultured, and identified from the abdominal contents of extinct bees preserved for 25 to 40 million years in buried Dominican amber. Rigorous surface decontamination of the amber and aseptic procedures were used during the recovery of the bacterium. Several lines of evidence indicated that the isolated bacterium was of ancient origin and not an extant contaminant. The characteristic enzymatic, biochemical, and 16S ribosomal DNA profiles indicated that the ancient bacterium is most closely related to extant Bacillus sphaericus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cano, R J -- Borucki, M K -- New York, N.Y. -- Science. 1995 May 19;268(5213):1060-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biological Sciences, California Polytechnic State University, San Luis Obispo 93407, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7538699" target="_blank"〉PubMed〈/a〉

    Inhibitors of HIV nucleocapsid protein zinc fingers as candidates for the treatment of AIDS (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-11-17
    Beschreibung: Strategies for the treatment of human immunodeficiency virus-type 1 (HIV-1) infection must contend with the obstacle of drug resistance. HIV-1 nucleocapsid protein zinc fingers are prime antiviral targets because they are mutationally intolerant and are required both for acute infection and virion assembly. Nontoxic disulfide-substituted benzamides were identified that attack the zinc fingers, inactivate cell-free virions, inhibit acute and chronic infections, and exhibit broad antiretroviral activity. The compounds were highly synergistic with other antiviral agents, and resistant mutants have not been detected. Zinc finger-reactive compounds may offer an anti-HIV strategy that restricts drug-resistance development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rice, W G -- Supko, J G -- Malspeis, L -- Buckheit, R W Jr -- Clanton, D -- Bu, M -- Graham, L -- Schaeffer, C A -- Turpin, J A -- Domagala, J -- Gogliotti, R -- Bader, J P -- Halliday, S M -- Coren, L -- Sowder, R C 2nd -- Arthur, L O -- Henderson, L E -- New York, N.Y. -- Science. 1995 Nov 17;270(5239):1194-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Antiviral Drug Mechanisms, PRI/DynCorp., National Cancer Institute-Frederick Cancer Research and Development Center, MD 21702, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502043" target="_blank"〉PubMed〈/a〉

    Similarity of sli-1, a regulator of vulval development in C. elegans, to the mammalian proto-oncogene c-cbl (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-08-25
    Beschreibung: Vulval induction during Caenorhabditis elegans development is mediated by LET-23, a homolog of the mammalian epidermal growth factor receptor tyrosine kinase. The sli-1 gene is a negative regulator of LET-23 and is shown here to encode a protein similar to c-Cbl, a mammalian proto-oncoprotein. SLI-1 and c-Cbl share approximately 55 percent amino acid identity over a stretch of 390 residues, which includes a C3HC4 zinc-binding motif known as the RING finger, and multiple consensus binding sites for Src homology 3 (SH3) domains. SLI-1 and c-Cbl may define a new class of proteins that modify receptor tyrosine kinase-mediated signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoon, C H -- Lee, J -- Jongeward, G D -- Sternberg, P W -- New York, N.Y. -- Science. 1995 Aug 25;269(5227):1102-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, California Institute of Technology, Pasadena 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7652556" target="_blank"〉PubMed〈/a〉

    Role of yeast insulin-degrading enzyme homologs in propheromone processing and bud site selection (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-10-20
    Beschreibung: The Saccharomyces cerevisiae AXL1 gene product Axl1p shares homology with the insulin-degrading enzyme family of endoproteases. Yeast axl1 mutants showed a defect in a-factor pheromone secretion, and a probable site of processing by Axl1p was identified within the a-factor precursor. In addition, Axl1p appears to function as a morphogenetic determinant for axial bud site selection. Amino acid substitutions within the presumptive active site of Axl1p caused defects in propheromone processing but failed to perturb bud site selection. Thus, Axl1p has been shown to participate in the dual regulation of distinct signaling pathways, and a member of the insulinase family has been implicated in propeptide processing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adames, N -- Blundell, K -- Ashby, M N -- Boone, C -- New York, N.Y. -- Science. 1995 Oct 20;270(5235):464-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Biology and Biochemistry, Simon Fraser University, Burnaby, British Columbia, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569998" target="_blank"〉PubMed〈/a〉

    Enhanced DNA-binding activity of a Stat3-related protein in cells transformed by the Src oncoprotein (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-07-07
    Beschreibung: Cytokines and growth factors induce tyrosine phosphorylation of signal transducers and activators of transcription (STATs) that directly activate gene expression. Cells stably transformed by the Src oncogene tyrosine kinase were examined for STAT protein activation. Assays of electrophoretic mobility, DNA-binding specificity, and antigenicity indicated that Stat3 or a closely related STAT family member was constitutively activated by the Src oncoprotein. Induction of this DNA-binding activity was accompanied by tyrosine phosphorylation of Stat3 and correlated with Src transformation. These findings demonstrate that Src can activate STAT signaling pathways and raise the possibility that Stat3 contributes to oncogenesis by Src.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yu, C L -- Meyer, D J -- Campbell, G S -- Larner, A C -- Carter-Su, C -- Schwartz, J -- Jove, R -- CA55652/CA/NCI NIH HHS/ -- DK34171/DK/NIDDK NIH HHS/ -- R01 DK034171/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):81-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of Michigan Medical School, Ann Arbor 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7541555" target="_blank"〉PubMed〈/a〉
