    Premature p34cdc2 activation required for apoptosis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-02-25
    Beschreibung: Activation of the serine-threonine kinase p34cdc2 at an inappropriate time during the cell cycle leads to cell death that resembles apoptosis. Premature activation of p34cdc2 was shown to be required for apoptosis induced by a lymphocyte granule protease. The kinase was rapidly activated and tyrosine dephosphorylated at the initiation of apoptosis. DNA fragmentation and nuclear collapse could be prevented by blocking p34cdc2 activity with excess peptide substrate, or by inactivating p34cdc2 in a temperature-sensitive mutant. Premature p34cdc2 activation may be a general mechanism by which cells induced to undergo apoptosis initiate the disruption of the nucleus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shi, L -- Nishioka, W K -- Th'ng, J -- Bradbury, E M -- Litchfield, D W -- Greenberg, A H -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1143-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Manitoba Institute of Cell Biology, University of Manitoba, Winnipeg, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8108732" target="_blank"〉PubMed〈/a〉

    The Met proto-oncogene mesenchymal to epithelial cell conversion (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-01-07
    Beschreibung: Coexpression of the human Met receptor and its ligand, hepatocyte growth factor/scatter factor (HGF/SF), in NIH 3T3 fibroblasts causes the cells to become tumorigenic in nude mice. The resultant tumors display lumen-like morphology, contain carcinoma-like focal areas with intercellular junctions resembling desmosomes, and coexpress epithelial (cytokeratin) and mesenchymal (vimentin) cytoskeletal markers. The tumor cells also display enhanced expression of desmosomal and tight-junction proteins. The apparent mesenchymal to epithelial conversion of the tumor cells mimics the conversion that occurs during embryonic kidney development, suggesting that Met-HGF/SF signaling plays a role in this process as well as in tumors that express both epithelial and mesenchymal markers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsarfaty, I -- Rong, S -- Resau, J H -- Rulong, S -- da Silva, P P -- Vande Woude, G F -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 7;263(5143):98-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ABL-Basic Research Program, National Cancer Institute (NCI)-Frederick Cancer Research and Development Center, MD 21702-1201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7505952" target="_blank"〉PubMed〈/a〉

    Treatment of murine lupus with CTLA4Ig (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-08-26
    Beschreibung: The interaction of B7-related molecules on antigen-presenting cells with CD28 or CTLA-4 antigens on T cells provides a second signal for T cell activation. Selection inhibition of the B7-CD28 or B7-CTLA-4 interactions produces antigen-specific T cell unresponsiveness in vitro and suppresses immune function in vivo. To determine whether selective inhibition of the B7-CD28 or B7-CTLA-4 interactions could suppress spontaneous autoimmune disease, a B7-binding protein was generated by genetic fusion of the extracellular domain of murine CTLA-4 to the Fc portion of a mouse immunoglobulin G2a monoclonal antibody (muCTLA4Ig). In lupus-prone NZB/NZW filial generation (F1) mice, treatment with muCTLA4Ig blocked autoantibody production and prolonged life, even when treatment was delayed until the most advanced stage of clinical illness. These findings suggest a possible role for human CTLA4Ig in the treatment of autoimmune diseases in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finck, B K -- Linsley, P S -- Wofsy, D -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1225-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, San Francisco.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7520604" target="_blank"〉PubMed〈/a〉

    Abnormal fear response and aggressive behavior in mutant mice deficient for alpha-calcium-calmodulin kinase II (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-10-14
    Beschreibung: Mice deficient for the gene encoding alpha-calcium-calmodulin-dependent kinase II (alpha-CaMKII knockout mice) provide a promising tool to link behavioral and cellular abnormalities with a specific molecular lesion. The heterozygous mouse exhibited a well-circumscribed syndrome of behavioral abnormalities, consisting primarily of a decreased fear response and an increase in defensive aggression, in the absence of any measured cognitive deficits. Unlike the heterozygote, the homozygote displayed abnormal behavior in all paradigms tested. At the cellular level, both extracellular and whole-cell patch clamp recordings indicated that serotonin release in putative serotonergic neurons of the dorsal raphe was reduced. Thus, alpha-CaMKII knockout mice, in particular the heterozygote, may provide a model for studying the molecular and cellular basis underlying emotional disorders involving fear and aggression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, C -- Rainnie, D G -- Greene, R W -- Tonegawa, S -- New York, N.Y. -- Science. 1994 Oct 14;266(5183):291-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Center for Cancer Research, Cambridge, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939668" target="_blank"〉PubMed〈/a〉

    Suppression of Ras-induced transformation of NIH 3T3 cells by activated G alpha s (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-04
    Beschreibung: Conversion of external signals into proliferative responses may be mediated by interactions between signaling pathways that control cell proliferation. Interactions between G alpha s, the alpha subunit of the heterotrimeric guanine nucleotide binding protein that stimulates adenylyl cyclase, and Ras, an important element in growth factor signaling, were studied. Expression of activated G alpha s in NIH 3T3 cells increased intracellular concentrations of adenosine 3',5'-monophosphate (cAMP) and inhibited H-Ras-stimulated DNA synthesis and mitogen-activated protein kinase activity. Activated G alpha s and 8-Br-cAMP suppressed H-Ras-induced transformation of NIH 3T3 cells. Apparently, G alpha s inhibits proliferative signals from Ras by stimulating cAMP production and activating protein kinase A.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, J -- Iyengar, R -- CA-44998/CA/NCI NIH HHS/ -- DK-38761/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 4;263(5151):1278-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Mount Sinai School of Medicine, City University of New York, NY 10029.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8122111" target="_blank"〉PubMed〈/a〉

    Functional participation of the IL-2 receptor gamma chain in IL-7 receptor complexes (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-11
    Beschreibung: The gamma chain of the interleukin-2 (IL-2) receptor is shared with the functional IL-4 receptor and is causatively related to X-linked severe combined immunodeficiency (XSCID), which is ascribed to a profound T cell defect. Studies with monoclonal antibodies specific for the IL-2 receptor gamma chain showed that the gamma chain participates in the functional high-affinity receptor complexes for IL-7 that are involved in the differentiation of T and B cells. Participation of the gamma subunit in more than one receptor may enable the elucidation of the mechanisms of XSCID development and lymphocyte differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kondo, M -- Takeshita, T -- Higuchi, M -- Nakamura, M -- Sudo, T -- Nishikawa, S -- Sugamura, K -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1453-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Tohoku University School of Medicine, Sendai, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128231" target="_blank"〉PubMed〈/a〉

    Regulatory T cell clones induced by oral tolerance: suppression of autoimmune encephalomyelitis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-08-26
    Beschreibung: Experimental autoimmune encephalomyelitis (EAE) is a cell-mediated autoimmune disease that serves as an animal model for multiple sclerosis. Oral administration of myelin basic protein (MBP) suppresses EAE by inducing peripheral tolerance. T cell clones were isolated from the mesenteric lymph nodes of SJL mice that had been orally tolerized to MBP. These clones were CD4+ and were structurally identical to T helper cell type 1 (TH1) encephalitogenic CD4+ clones in T cell receptor usage, major histocompatibility complex restriction, and epitope recognition. However, they produced transforming growth factor-beta with various amounts of interleukin-4 and interleukin-10 and suppressed EAE induced with either MBP or proteolipid protein. Thus, mucosally derived TH2-like clones induced by oral antigen can actively regulate immune responses in vivo and may represent a different subset of T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Y -- Kuchroo, V K -- Inobe, J -- Hafler, D A -- Weiner, H L -- AR/A143220/AR/NIAMS NIH HHS/ -- NS29352/NS/NINDS NIH HHS/ -- NS30843/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1237-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7520605" target="_blank"〉PubMed〈/a〉

    Regulation of IgE responses to inhaled antigen in mice by antigen-specific gamma delta T cells (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-23
    Beschreibung: Indirect evidence implicates gamma delta T cells in the cross-regulation of CD4 alpha beta T cell responses. Adoptive transfer of small numbers of gamma delta T cells from ovalbumin (OVA)-tolerant mice selectively suppressed TH2-dependent immunoglobulin E (IgE) antibody production without affecting parallel IgG responses. Challenge of these gamma delta T cells in vitro with specific antigen resulted in production of high levels of interferon gamma. The effects of the gamma delta T cells may be mediated by direct inhibition of OVA-specific CD4+ TH2 cell proliferation or selection for specific CD4 TH2 cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McMenamin, C -- Pimm, C -- McKersey, M -- Holt, P G -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1869-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cell Biology, Institute for Child Health Research, West Perth, Western Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7916481" target="_blank"〉PubMed〈/a〉

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

    Thalamic abnormalities in schizophrenia visualized through magnetic resonance image averaging (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-10-14
    Beschreibung: Schizophrenia is a complex illness characterized by multiple types of symptoms involving many aspects of cognition and emotion. Most efforts to identify its underlying neural substrates have focused on a strategy that relates a single symptom to a single brain region. An alternative hypothesis, that the variety of symptoms could be explained by a lesion in midline neural circuits mediating attention and information processing, is explored. Magnetic resonance images from patients and controls were transformed with a "bounding box" to produce an "average schizophrenic brain" and an "average normal brain." After image subtraction of the two averages, the areas of difference were displayed as an effect size map. Specific regional abnormalities were observed in the thalamus and adjacent white matter. An abnormality in the thalamus and related circuitry explains the diverse symptoms of schizophrenia parsimoniously because they could all result from a defect in filtering or gating sensory input, which is one of the primary functions of the thalamus in the human brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andreasen, N C -- Arndt, S -- Swayze, V 2nd -- Cizadlo, T -- Flaum, M -- O'Leary, D -- Ehrhardt, J C -- Yuh, W T -- MH31593/MH/NIMH NIH HHS/ -- MH40856/MH/NIMH NIH HHS/ -- MHCRC 43271/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Oct 14;266(5183):294-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mental Health Clinical Research Center, College of Medicine.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939669" target="_blank"〉PubMed〈/a〉

    Beschreibung: Endogenous DNA adducts may contribute to the etiology of human genetic disease and cancer. One potential source of endogenous DNA adducts is lipid peroxidation, which generates mutagenic carbonyl compounds such as malondialdehyde. A sensitive mass spectrometric method permitted detection and quantitation of the major malondialdehyde-DNA adduct, a pyrimidopurinone derived from deoxyguanosine. DNA from disease-free human liver was found to contain 5400 adducts per cell, a frequency comparable to that of adducts formed by exogenous carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chaudhary, A K -- Nokubo, M -- Reddy, G R -- Yeola, S N -- Morrow, J D -- Blair, I A -- Marnett, L J -- CA47479/CA/NCI NIH HHS/ -- ES00267/ES/NIEHS NIH HHS/ -- GM42056/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 9;265(5178):1580-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉A.

    Sequestration of GPI-anchored proteins in caveolae triggered by cross-linking (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-24
    Beschreibung: Glycosyl-phosphatidylinositol (GPI)-anchored proteins have been reported to reside in clusters collected over small membrane invaginations called caveolae. The detection of different GPI-anchored proteins with fluorescently labeled monoclonal antibodies showed that these proteins are not constitutively concentrated in caveolae; they enter these structures independently after cross-linking with polyclonal secondary antibodies. Analysis of the cell surface distribution of the GPI-anchored folate receptor by electron microscopy confirms these observations. Thus, multimerization of GPI-anchored proteins regulates their sequestration in caveolae, but in the absence of agents that promote clustering they are diffusely distributed over the plasma membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mayor, S -- Rothberg, K G -- Maxfield, F R -- DK27083/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1948-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, College of Physicians and Surgeons, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7516582" target="_blank"〉PubMed〈/a〉

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

    Role of TCR zeta chain in T cell development and selection (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-11
    Beschreibung: Signals mediated by the T cell receptor (TCR) are required for thymocyte maturation and selection. To examine the role of TCR zeta chain signals in development, TCR expression was restored in zeta-deficient mice with transgenic zeta chains that partially or completely lacked sequences required for signal transduction. The zeta chain played a role in thymic development by promoting TCR surface expression, but zeta-mediated signals were not essential because TCRs that contained signaling-deficient zeta chains promoted T cell maturation and transduced signals associated with thymic selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shores, E W -- Huang, K -- Tran, T -- Lee, E -- Grinberg, A -- Love, P E -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1047-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematologic Products, Food and Drug Administration, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7526464" target="_blank"〉PubMed〈/a〉

    Cooperative display and relatedness among males in a lek-mating bird (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-11
    Beschreibung: Long-tailed manakins mate in leks and cooperate in multiyear male-male partnerships. An alpha male is responsible for virtually all mating, whereas a beta male assists in the courtship displays. Such altruism by the beta male poses a problem for evolutionary theory because most theoretical treatments and empirical examples of cooperative behavior involve kin selection or reciprocity. Here it is shown that alpha and beta partners are not relatives and that reciprocity is not involved. Instead, direct, though long-delayed benefits to beta males are demonstrated, which include rare copulations, ascension to alpha status, and female lek fidelity. These benefits maintain this unusual form of male-male cooperation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDonald, D B -- Potts, W K -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1030-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Archbold Biological Station, Lake Placid, FL 33852-2057.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973654" target="_blank"〉PubMed〈/a〉

    Inhibition of NF-kappa B by sodium salicylate and aspirin (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-08-12
    Beschreibung: The transcription factor nuclear factor-kappa B (NF-kappa B) is critical for the inducible expression of multiple cellular and viral genes involved in inflammation and infection including interleukin-1 (IL-1), IL-6, and adhesion molecules. The anti-inflammatory drugs sodium salicylate and aspirin inhibited the activation of NF-kappa B, which further explains the mechanism of action of these drugs. This inhibition prevented the degradation of the NF-kappa B inhibitor, I kappa B, and therefore NF-kappa B was retained in the cytosol. Sodium salicylate and aspirin also inhibited NF-kappa B-dependent transcription from the Ig kappa enhancer and the human immunodeficiency virus (HIV) long terminal repeat (LTR) in transfected T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kopp, E -- Ghosh, S -- R01 AI 33443-01A1/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 12;265(5174):956-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Yale University School of Medicine, New Haven, CT 06536.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8052854" target="_blank"〉PubMed〈/a〉

    Beschreibung: The European wild boar was crossed with the domesticated Large White pig to genetically dissect phenotypic differences between these populations for growth and fat deposition. The most important effects were clustered on chromosome 4, with a single region accounting for a large part of the breed difference in growth rate, fatness, and length of the small intestine. The study is an advance in genome analyses and documents the usefulness of crosses between divergent outbred populations for the detection and characterization of quantitative trait loci. The genetic mapping of a major locus for fat deposition in the pig could have implications for understanding human obesity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersson, L -- Haley, C S -- Ellegren, H -- Knott, S A -- Johansson, M -- Andersson, K -- Andersson-Eklund, L -- Edfors-Lilja, I -- Fredholm, M -- Hansson, I -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1771-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Animal Breeding and Genetics, Swedish University of Agricultural Sciences, Uppsala.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134840" target="_blank"〉PubMed〈/a〉

    Beschreibung: Estrogen hormones produce physiological actions within a variety of target sites in the body and during development by activating a specific receptor protein. Hormone responsiveness for the estrogen receptor protein was investigated at different stages of development with the use of gene knockout techniques because no natural genetic mutants have been described. A mutant mouse line without a functional estrogen receptor was created and is being used to assess estrogen responsiveness. Both sexes of these mutant animals are infertile and show a variety of phenotypic changes, some of which are associated with the gonads, mammary glands, reproductive tracts, and skeletal tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korach, K S -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1524-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Receptor Biology Section, National Institute of Environmental Health Sciences, National Institutes of Health, Research Triangle Park, NC 27709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985022" target="_blank"〉PubMed〈/a〉

    Beschreibung: Fas is an apoptosis-signaling receptor molecule on the surface of a number of cell types. Molecular cloning and nucleotide sequence analysis revealed a human Fas messenger RNA variant capable of encoding a soluble Fas molecule lacking the transmembrane domain because of the deletion of an exon encoding this region. The expression of soluble Fas was confirmed by flow cytometry and immunocytochemical analysis. Supernatants from cells transfected with the variant messenger RNA blocked apoptosis induced by the antibody to Fas. Levels of soluble Fas were elevated in patients with systemic lupus erythematosus, and mice injected with soluble Fas displayed autoimmune features.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheng, J -- Zhou, T -- Liu, C -- Shapiro, J P -- Brauer, M J -- Kiefer, M C -- Barr, P J -- Mountz, J D -- P01 AR03555/AR/NIAMS NIH HHS/ -- P50 AI23694/AI/NIAID NIH HHS/ -- P60 AR20614/AR/NIAMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1759-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Alabama at Birmingham.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7510905" target="_blank"〉PubMed〈/a〉

    Effect of the nigrostriatal dopamine system on acquired neural responses in the striatum of behaving monkeys (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-07-15
    Beschreibung: Dysfunction of the nigrostriatal dopamine system results in marked disorders of movement such as occur in Parkinson's disease. Functions of this dopamine-containing projection system were examined in monkeys trained in a classical conditioning task, and the effects of striatal dopamine depletion were tested. Unilateral dopamine loss substantially reduced the acquired sensory responsiveness of striatal neurons monitored electrophysiologically. This effect was ipsilateral and selective, and could be reversed by apomorphine. These results suggest that the primate nigrostriatal system modulates expression of neuronal response plasticity in the striatum during sensorimotor learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aosaki, T -- Graybiel, A M -- Kimura, M -- R01 NS25529/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jul 15;265(5170):412-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023166" target="_blank"〉PubMed〈/a〉

    Mediation of c-Myc-induced apoptosis by p53 (1994)

    Details
    Publikationsdatum: 1994-09-30
    Beschreibung: The cellular proto-oncogene c-myc is involved in cell proliferation and transformation but is also implicated in the induction of programmed cell death (apoptosis). The same characteristics have been described for the tumor suppressor gene p53, the most commonly mutated gene in human cancer. In quiescent mouse fibroblasts expressing wild-type p53 protein, activation of c-Myc was found to induce apoptosis and cell cycle reentry, preceded by stabilization of p53. In contrast, in quiescent p53-null fibroblasts, activation of c-Myc induced cell cycle reentry but not apoptosis. These results suggest that p53 mediates apoptosis as a safeguard mechanism to prevent cell proliferation induced by oncogene activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hermeking, H -- Eick, D -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2091-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Klinische Molekularbiologie und Tumorgenetik Forschungszentrum fur Umwelt und Gesundheit, GSF, Munchen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091232" target="_blank"〉PubMed〈/a〉

    Mutagenesis and mapping of a mouse gene, Clock, essential for circadian behavior (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-29
    Beschreibung: In a search for genes that regulate circadian rhythms in mammals, the progeny of mice treated with N-ethyl-N-nitrosourea (ENU) were screened for circadian clock mutations. A semidominant mutation, Clock, that lengthens circadian period and abolishes persistence of rhythmicity was identified. Clock segregated as a single gene that mapped to the midportion of mouse chromosome 5, a region syntenic to human chromosome 4. The power of ENU mutagenesis combined with the ability to clone murine genes by map position provides a generally applicable approach to study complex behavior in mammals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3839659/" 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/PMC3839659/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vitaterna, M H -- King, D P -- Chang, A M -- Kornhauser, J M -- Lowrey, P L -- McDonald, J D -- Dove, W F -- Pinto, L H -- Turek, F W -- Takahashi, J S -- P30-CA07175/CA/NCI NIH HHS/ -- R01-DK40493/DK/NIDDK NIH HHS/ -- T32 NS071040/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- etc. -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):719-25.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Physiology, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171325" target="_blank"〉PubMed〈/a〉

    Activation of phosphatidylinositol-3' kinase by Src-family kinase SH3 binding to the p85 subunit (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-18
    Beschreibung: Engagement of antigen receptor complexes induces rapid activation of Src-family kinases and association with phosphatidylinositol-3' kinase (PI-3 kinase). Here it was found that the Src homology 3 (SH3) domain of Lyn and Fyn bound to a proline-rich region (residues 84 to 99) within the 85-kilodalton subunit (p85) of PI-3 kinase. The binding of SH3 to the purified kinase led to a five- to sevenfold increase in the specific activity of PI-3 kinase. Ligand-induced receptor stimulation activated PI-3 kinase, and this activation was blocked by a peptide containing residues 84 to 99 of p85. These data demonstrate a mechanism for PI-3 kinase activation and show that binding of SH3 domains to proline-rich target sequences can regulate enzymatic activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pleiman, C M -- Hertz, W M -- Cambier, J C -- A120519/PHS HHS/ -- A121768/PHS HHS/ -- A129903/PHS HHS/ -- New York, N.Y. -- Science. 1994 Mar 18;263(5153):1609-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, National Jewish Center for Immunology and Respiratory Medicine, Denver, CO 80206.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128248" target="_blank"〉PubMed〈/a〉

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

    Formation of nascent intercalated disks between grafted fetal cardiomyocytes and host myocardium (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-01
    Beschreibung: Fetal cardiomyocytes isolated from transgenic mice carrying a fusion gene of the alpha-cardiac myosin heavy chain promoter with a beta-galactosidase reporter were examined for their ability to form stable intracardiac grafts. Embryonic day 15 transgenic cardiomyocytes delivered directly into the myocardium of syngeneic hosts formed stable grafts, as identified by nuclear beta-galactosidase activity. Grafted cardiomyocytes were observed as long as 2 months after implantation, the latest date assayed. Intracardiac graft formation did not induce overtly negative effects on the host myocardium and was not associated with chronic immune rejection. Electron microscopy revealed the presence of nascent intercalated disks connecting the engrafted fetal cardiomyocytes and the host myocardium. These results suggest that intracardiac grafting might provide a useful approach for myocardial repair, provided that the grafted cells can contribute to myocardial function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soonpaa, M H -- Koh, G Y -- Klug, M G -- Field, L J -- HL45453/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):98-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Krannert Institute of Cardiology, Indiana University School of Medicine, Indianapolis 46202-4800.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140423" target="_blank"〉PubMed〈/a〉

    Role of bone marrow-derived cells in presenting MHC class I-restricted tumor antigens (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-05-13
    Beschreibung: Many tumors express tumor-specific antigens capable of being presented to CD8+ T cells by major histocompatibility complex (MHC) class I molecules. Antigen presentation models predict that the tumor cell itself should present these antigens to T cells. However, when conditions for the priming of tumor-specific responses were examined in mice, no detectable presentation of MHC class I-restricted tumor antigens by the tumor itself was found. Rather, tumor antigens were exclusively presented by host bone marrow-derived cells. Thus, MHC class I-restricted antigens are efficiently transferred in vivo to bone marrow-derived antigen-presenting cells, which suggests that human leukocyte antigen matching may be less critical in the application of tumor vaccines than previously thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, A Y -- Golumbek, P -- Ahmadzadeh, M -- Jaffee, E -- Pardoll, D -- Levitsky, H -- New York, N.Y. -- Science. 1994 May 13;264(5161):961-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7513904" target="_blank"〉PubMed〈/a〉

    Effects of cerebral ischemia in mice deficient in neuronal nitric oxide synthase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-23
    Beschreibung: The proposal that nitric oxide (NO) or its reactant products mediate toxicity in brain remains controversial in part because of the use of nonselective agents that block NO formation in neuronal, glial, and vascular compartments. In mutant mice deficient in neuronal NO synthase (NOS) activity, infarct volumes decreased significantly 24 and 72 hours after middle cerebral artery occlusion, and the neurological deficits were less than those in normal mice. This result could not be accounted for by differences in blood flow or vascular anatomy. However, infarct size in the mutant became larger after endothelial NOS inhibition by nitro-L-arginine administration. Hence, neuronal NO production appears to exacerbate acute ischemic injury, whereas vascular NO protects after middle cerebral artery occlusion. The data emphasize the importance of developing selective inhibitors of the neuronal isoform.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Z -- Huang, P L -- Panahian, N -- Dalkara, T -- Fishman, M C -- Moskowitz, M A -- NS10828/NS/NINDS NIH HHS/ -- NS2636/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1883-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stroke Research Laboratory, Massachusetts General Hospital, Charlestown 02129.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7522345" target="_blank"〉PubMed〈/a〉

    Beschreibung: Many recent studies have implicated dietary factors in the cause and prevention of important diseases, including cancer, coronary heart disease, birth defects, and cataracts. There is strong evidence that vegetables and fruits protect against these diseases; however, the active constituents are incompletely identified. Whether fat per se is a major cause of disease is a question still under debate, although saturated and partially hydrogenated fats probably increase the risk of coronary heart disease. One clear conclusion from existing epidemiologic evidence is that many individuals in the United States have suboptimal diets and that the potential for disease prevention by improved nutrition is substantial.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willett, W C -- New York, N.Y. -- Science. 1994 Apr 22;264(5158):532-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Nutrition, Harvard School of Public Health, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8160011" target="_blank"〉PubMed〈/a〉

    A specific inhibitor of the epidermal growth factor receptor tyrosine kinase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-08-19
    Beschreibung: A small molecule called PD 153035 inhibited the epidermal growth factor (EGF) receptor tyrosine kinase with a 5-pM inhibition constant. The inhibitor was specific for the EGF receptor tyrosine kinase and inhibited other purified tyrosine kinases only at micromolar or higher concentrations. PD 153035 rapidly suppressed autophosphorylation of the EGF receptor at low nanomolar concentrations in fibroblasts or in human epidermoid carcinoma cells and selectively blocked EGF-mediated cellular processes including mitogenesis, early gene expression, and oncogenic transformation. PD 153035 demonstrates an increase in potency over that of other tyrosine kinase inhibitors of four to five orders of magnitude for inhibition of isolated EGF receptor tyrosine kinase and three to four orders of magnitude for inhibition of cellular phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fry, D W -- Kraker, A J -- McMichael, A -- Ambroso, L A -- Nelson, J M -- Leopold, W R -- Connors, R W -- Bridges, A J -- New York, N.Y. -- Science. 1994 Aug 19;265(5175):1093-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Parke-Davis Pharmaceutical Research, Division of Warner-Lambert Company, Ann Arbor, MI 48105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066447" target="_blank"〉PubMed〈/a〉

    Inhibition of hepatic chylomicron remnant uptake by gene transfer of a receptor antagonist (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-03
    Beschreibung: The low density lipoprotein receptor-related protein (LRP) has been proposed to mediate in concert with the LDL receptor (LDLR) the uptake of dietary lipoproteins into the hepatocytes. This hypothesis was tested by transient inactivation of LRP in vivo. Receptor-associated protein (RAP), a dominant negative regulator of LRP function, was transferred by an adenoviral vector to the livers of mice lacking LDLR (LDLR-/-). The inactivation of LRP by RAP was associated with a marked accumulation of chylomicron remnants in LDLR-/- mice and to a lesser degree in normal mice, suggesting that both LDLR and LRP are involved in remnant clearance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willnow, T E -- Sheng, Z -- Ishibashi, S -- Herz, J -- HL20948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1471-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7515194" target="_blank"〉PubMed〈/a〉

    Association of the protein kinases c-Bcr and Bcr-Abl with proteins of the 14-3-3 family (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-10-07
    Beschreibung: In this study, a protein that interacts with sequences encoded by the first exon of the protein kinase Bcr was cloned. The Bcr-associated protein 1 (Bap-1) is a member of the 14-3-3 family of proteins. Bap-1 interacts with full-length c-Bcr and with the chimeric Bcr-Abl tyrosine kinase of Philadelphia chromosome (Ph1)-positive human leukemias. Bap-1 is a substrate for the Bcr serine-threonine kinase and is also phosphorylated on tyrosine by Bcr-Abl but not by c-Abl. Bap-1 may function in the regulation of c-Bcr and may contribute to the transforming activity of Bcr-Abl in vivo. 14-3-3 proteins are essential for cell proliferation and have a role in determining the timing of mitosis in yeast. Through direct binding to sequences present in Bcr and in other proteins implicated in signaling, the mammalian 14-3-3 proteins may link specific signaling protein components to mitogenic and cell-cycle control pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reuther, G W -- Fu, H -- Cripe, L D -- Collier, R J -- Pendergast, A M -- CA61033/CA/NCI NIH HHS/ -- DK01965/DK/NIDDK NIH HHS/ -- GM07184/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Oct 7;266(5182):129-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939633" target="_blank"〉PubMed〈/a〉

    Targeting of G alpha i2 to the Golgi by alternative spliced carboxyl-terminal region (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-01-07
    Beschreibung: Heterotrimeric guanosine triphosphate (GTP)-binding proteins (G proteins) may participate in membrane traffic events. A complementary DNA (cDNA) was isolated from a mouse pituitary cDNA library that corresponded to an alternatively spliced form of the gene encoding the G protein alpha subunit G alpha i2. The cDNA was identical to that encoding G alpha i2 except that the region encoding for the carboxyl-terminal 24 amino acids was replaced by a longer region encoding 35 amino acids that have no sequence similarity with G alpha i2 or other members of the G protein family. This alternative spliced product and the corresponding protein (sGi2) were present in several tissues. Specific antibodies revealed that sGi2 was localized in the Golgi apparatus, suggesting a role in membrane transport. Thus, alternative splicing may generate from a single gene two G protein alpha subunits with differential cellular localization and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Montmayeur, J P -- Borrelli, E -- New York, N.Y. -- Science. 1994 Jan 7;263(5143):95-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes, CNRS, INSERM U184, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8272874" target="_blank"〉PubMed〈/a〉

    Degeneration of a nonrecombining chromosome (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-01-14
    Beschreibung: Comparative studies suggest that sex chromosomes begin as ordinary autosomes that happen to carry a major sex determining locus. Over evolutionary time the Y chromosome is selected to stop recombining with the X chromosome, perhaps in response to accumulation of alleles beneficial to the heterogametic but harmful to the homogametic sex. Population genetic theory predicts that a nonrecombining Y chromosome should degenerate. Here this prediction is tested by application of specific selection pressures to Drosophila melanogaster populations. Results demonstrate the decay of a nonrecombining, nascent Y chromosome and the capacity for recombination to ameliorate such decay.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rice, W R -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):230-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, Santa Cruz 95064.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8284674" target="_blank"〉PubMed〈/a〉

    Localization of a breast cancer susceptibility gene, BRCA2, to chromosome 13q12-13 (1994)

    Details
    Publikationsdatum: 1994-09-30
    Beschreibung: A small proportion of breast cancer, in particular those cases arising at a young age, is due to the inheritance of dominant susceptibility genes conferring a high risk of the disease. A genomic linkage search was performed with 15 high-risk breast cancer families that were unlinked to the BRCA1 locus on chromosome 17q21. This analysis localized a second breast cancer susceptibility locus, BRCA2, to a 6-centimorgan interval on chromosome 13q12-13. Preliminary evidence suggests that BRCA2 confers a high risk of breast cancer but, unlike BRCA1, does not confer a substantially elevated risk of ovarian cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wooster, R -- Neuhausen, S L -- Mangion, J -- Quirk, Y -- Ford, D -- Collins, N -- Nguyen, K -- Seal, S -- Tran, T -- Averill, D -- CA-48711/CA/NCI NIH HHS/ -- CN-05222/CN/NCI NIH HHS/ -- HG-00571/HG/NHGRI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2088-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Molecular Carcinogenesis, Institute of Cancer Research, Sutton, Surrey, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091231" target="_blank"〉PubMed〈/a〉

    Replacement of diseased mouse liver by hepatic cell transplantation (1994)

    Beschreibung: Adult liver has the unusual ability to fully regenerate after injury. Although regeneration is accomplished by the division of mature hepatocytes, the replicative potential of these cells is unknown. Here, the replicative capacity of adult liver cells and their medical usefulness as donor cells for transplantation were investigated by transfer of adult mouse liver cells into transgenic mice that display an endogenous defect in hepatic growth potential and function. The transplanted liver cell populations replaced up to 80 percent of the diseased recipient liver. These findings demonstrate the enormous growth potential of adult hepatocytes, indicating the feasibility of liver cell transplantation as a method to replace lost or diseased hepatic parenchyma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhim, J A -- Sandgren, E P -- Degen, J L -- Palmiter, R D -- Brinster, R L -- HD-23657/HD/NICHD NIH HHS/ -- HD09172/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1149-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Animal Biology, School of Veterinary Medicine, University of Pennsylvania, Philadelphia 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8108734" target="_blank"〉PubMed〈/a〉

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

    Genetics of a pheromonal difference contributing to reproductive isolation in Drosophila (1994)

    Publikationsdatum: 1994-09-02
    Beschreibung: Although sexual isolation is one of the most important causes of speciation, its genetic basis is largely unknown. Here evidence is presented that suggests that sexual isolation between two closely related species of Drosophila is largely caused by differences in female cuticular hydrocarbons. This difference maps to only one of the three major chromosomes, implying that reproductive isolation might have a fairly simple genetic basis. The effect of the hydrocarbons on courtship may help explain the ubiquitous asymmetry of sexual isolation between many pairs of Drosophila species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coyne, J A -- Crittenden, A P -- Mah, K -- GM 38462/GM/NIGMS NIH HHS/ -- GM 50355/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1461-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073292" target="_blank"〉PubMed〈/a〉

    Autoantibodies to glutamate receptor GluR3 in Rasmussen's encephalitis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-07-29
    Beschreibung: Rasmussen's encephalitis is a progressive childhood disease of unknown cause characterized by severe epilepsy, hemiplegia, dementia, and inflammation of the brain. During efforts to raise antibodies to recombinant glutamate receptors (GluRs), behaviors typical of seizures and histopathologic features mimicking Rasmussen's encephalitis were found in two rabbits immunized with GluR3 protein. A correlation was found between the presence of Rasmussen's encephalitis and serum antibodies to GluR3 detected by protein immunoblot analysis and by immunoreactivity to transfected cells expressing GluR3. Repeated plasma exchanges in one seriously ill child transiently reduced serum titers of GluR3 antibodies, decreased seizure frequency, and improved neurologic function. Thus, GluR3 is an autoantigen in Rasmussen's encephalitis, and an autoimmune process may underlie this disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogers, S W -- Andrews, P I -- Gahring, L C -- Whisenand, T -- Cauley, K -- Crain, B -- Hughes, T E -- Heinemann, S F -- McNamara, J O -- NS17771/NS/NINDS NIH HHS/ -- NS28709/NS/NINDS NIH HHS/ -- NS30990R29/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jul 29;265(5172):648-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Salt Lake City Geriatric Research Education and Clinical Center, Veterans Affairs Medical Center, UT.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036512" target="_blank"〉PubMed〈/a〉

    The thermal grill illusion: unmasking the burn of cold pain (1994)

    Details
    Publikationsdatum: 1994-07-08
    Beschreibung: In Thunberg's thermal grill illusion, first demonstrated in 1896, a sensation of strong, often painful heat is elicited by touching interlaced warm and cool bars to the skin. Neurophysiological recordings from two classes of ascending spinothalamic tract neurons that are sensitive to innocuous or noxious cold showed differential responses to the grill. On the basis of these results, a simple model of central disinhibition, or unmasking, predicted a quantitative correspondence between grill-evoked pain and cold-evoked pain, which was verified psychophysically. This integration of pain and temperature can explain the thermal grill illusion and the burning sensation of cold pain and may also provide a basis for the cold-evoked, burning pain of the classic thalamic pain syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Craig, A D -- Bushnell, M C -- DA07402/DA/NIDA NIH HHS/ -- NS25616/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jul 8;265(5169):252-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neurobiology, Barrow Neurological Institute, Phoenix, AZ 85013.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023144" target="_blank"〉PubMed〈/a〉

    Specification of C/EBP function during Drosophila development by the bZIP basic region (1994)

    Publikationsdatum: 1994-12-16
    Beschreibung: The biologically relevant interactions of a transcription factor are those that are important for function in the organism. Here, a transgenic rescue assay was used to determine which molecular functions of Drosophila CCAAT/enhancer binding protein (C/EBP), a basic region-leucine zipper transcription factor, are required for it to fulfill its essential role during development. Chimeric proteins that contain the Drosophila C/EBP (DmC/EBP) basic region, a heterologous zipper, and a heterologous activation domain could functionally substitute for DmC/EBP. Mammalian C/EBPs were also functional in Drosophila. In contrast, 9 of 25 single amino acid substitutions in the basic region disrupted biological function. Thus, the conserved basic region specifies DmC/EBP activity in the organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rorth, P -- New York, N.Y. -- Science. 1994 Dec 16;266(5192):1878-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Embryology, Carnegie Institution of Washington, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7997882" target="_blank"〉PubMed〈/a〉

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

    Implantation and the placenta: key pieces of the development puzzle (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-12-02
    Beschreibung: The mammalian embryo cannot develop without the placenta. Its specialized cells (trophoblast, endoderm, and extraembryonic mesoderm) form early in development. They attach the embryo to the uterus (implantation) and form vascular connections necessary for nutrient transport. In addition, the placenta redirects maternal endocrine, immune, and metabolic functions to the embryo's advantage. These complex activities are sensitive to disruption, as shown by the high incidence of early embryonic mortality and pregnancy diseases in humans, as well as the numerous peri-implantation lethal mutations in mice. Integration of molecular and developmental approaches has recently produced insights into the molecules that control these processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cross, J C -- Werb, Z -- Fisher, S J -- HD 22210/HD/NICHD NIH HHS/ -- HD 26732/HD/NICHD NIH HHS/ -- HD 30367/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1508-18.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985020" target="_blank"〉PubMed〈/a〉

    Functional role of type I and type II interferons in antiviral defense (1994)

    Details
    Publikationsdatum: 1994-06-24
    Beschreibung: Mice lacking the known subunit of the type I interferon (IFN) receptor were completely unresponsive to type I IFNs, suggesting that this receptor chain is essential for type I IFN-mediated signal transduction. These mice showed no overt anomalies but were unable to cope with viral infections, despite otherwise normal immune responses. Comparison of mice lacking either type I or type II IFN receptors showed that, at least in response to some viruses, both IFN systems are essential for antiviral defense and are functionally nonredundant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muller, U -- Steinhoff, U -- Reis, L F -- Hemmi, S -- Pavlovic, J -- Zinkernagel, R M -- Aguet, M -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1918-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Biology I, University of Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009221" target="_blank"〉PubMed〈/a〉

    Correction of lethal intestinal defect in a mouse model of cystic fibrosis by human CFTR (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-12-09
    Beschreibung: Cystic fibrosis (CF) is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR). A potential animal model of CF, the CFTR-/- mouse, has had limited utility because most mice die from intestinal obstruction during the first month of life. Human CFTR (hCFTR) was expressed in CFTR-/- mice under the control of the rat intestinal fatty acid-binding protein gene promoter. The mice survived and showed functional correction of ileal goblet cell and crypt cell hyperplasia and cyclic adenosine monophosphate-stimulated chloride secretion. These results support the concept that transfer of the hCFTR gene may be a useful strategy for correcting physiologic defects in patients with CF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, L -- Dey, C R -- Wert, S E -- DuVall, M D -- Frizzell, R A -- Whitsett, J A -- DK38518/DK/NIDDK NIH HHS/ -- HL49004/HL/NHLBI NIH HHS/ -- HL51832/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1705-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Children's Hospital Medical Center, Division of Pulmonary Biology, Cincinnati, OH 45229-3039.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7527588" target="_blank"〉PubMed〈/a〉

    Implications of FRA16A structure for the mechanism of chromosomal fragile site genesis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-24
    Beschreibung: Fragile sites are chemically induced nonstaining gaps in chromosomes. Different fragile sites vary in frequency in the population and in the chemistry of their induction. DNA sequences encompassing and including the rare, autosomal, folate-sensitive fragile site, FRA16A, were isolated by positional cloning. The molecular basis of FRA16A was found to be expansion of a normally polymorphic p(CCG)n repeat. This repeat was adjacent to a CpG island that was methylated in fragile site-expressing individuals. The FRA16A locus in individuals who do not express the fragile site is not a site of DNA methylation (imprinting), which suggests that the methylation associated with fragile sites may be a consequence and not a cause of their genesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nancarrow, J K -- Kremer, E -- Holman, K -- Eyre, H -- Doggett, N A -- Le Paslier, D -- Callen, D F -- Sutherland, G R -- Richards, R I -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1938-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cytogenetics and Molecular Genetics, Women's and Children's Hospital, North Adelaide, South Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009225" target="_blank"〉PubMed〈/a〉

    Prophylactic vaccines, risk behavior change, and the probability of eradicating HIV in San Francisco (1994)

    Beschreibung: Theory is linked with data to assess the probability of eradicating human immunodeficiency virus (HIV) in San Francisco through the use of prophylactic vaccines. The necessary vaccine efficacy levels and population coverage levels for eradication are quantified. The likely impact of risk behavior changes on vaccination campaigns is assessed. The results show it is unlikely that vaccines will be able to eradicate HIV in San Francisco unless they are combined with considerable reductions in risk behaviors. Furthermore, if risk behavior increases as the result of a vaccination campaign, then vaccination could result in a perverse outcome by increasing the severity of the epidemic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blower, S M -- McLean, A R -- 1R29DA08153/DA/NIDA NIH HHS/ -- AI33831/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1451-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Epidemiology Department, School of Public Health, University of California at Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073289" target="_blank"〉PubMed〈/a〉

    Forward and reverse genetic approaches to behavior in the mouse (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-17
    Beschreibung: Modern molecular genetic and genomic approaches are revolutionizing the study of behavior in the mouse. "Reverse genetics" (from gene to phenotype) with targeted gene transfer provides a powerful tool to dissect behavior and has been used successfully to study the effects of null mutations in genes implicated in the regulation of long-term potentiation and spatial learning in mice. In addition, "forward genetics" (from phenotype to gene) with high-efficiency mutagenesis in the mouse can uncover unknown genes and has been used to isolate a behavioral mutant of the circadian system. With the recent availability of high-density genetic maps and physical mapping resources, positional cloning of virtually any mutation is now feasible in the mouse. Together, these approaches permit a molecular analysis of both known and previously unknown genes regulating behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830945/" 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/PMC3830945/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, J S -- Pinto, L H -- Vitaterna, M H -- EY08467/EY/NEI NIH HHS/ -- MH39592/MH/NIMH NIH HHS/ -- MH49241/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- etc. -- New York, N.Y. -- Science. 1994 Jun 17;264(5166):1724-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Physiology, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8209253" target="_blank"〉PubMed〈/a〉

    Requirement of a critical period of transcription for induction of a late phase of LTP (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-08-19
    Beschreibung: Repeated high-frequency trains of stimuli induce long-term potentiation (LTP) in the CA1 region that persists for up to 8 hours in hippocampal slices and for days in intact animals. This long time course has made LTP an attractive model for certain forms of long-term memory in the mammalian brain. A hallmark of long-term memory in the intact animal is a requirement for transcription, and thus whether the late phase of LTP (L-LTP) requires transcription was investigated here. With the use of different inhibitors, it was found in rat hippocampal slices that the induction of L-LTP [produced either by tetanic stimulation or by application of the cyclic adenosine monophosphate (cAMP) analog Sp-cAMPS (Sp-cyclic adenosine 3',5'-monophosphorothioate)] was selectively prevented when transcription was blocked immediately after tetanization or during application of cAMP. As with behavioral memory, this requirement for transcription had a critical time window. Thus, the late phase of LTP in the CA1 region requires transcription during a critical period, perhaps because cAMP-inducible genes must be expressed during this period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nguyen, P V -- Abel, T -- Kandel, E R -- GM32099/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 19;265(5175):1104-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, New York, NY.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066450" target="_blank"〉PubMed〈/a〉

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

    Fas and perforin pathways as major mechanisms of T cell-mediated cytotoxicity (1994)

    Details
    Publikationsdatum: 1994-07-22
    Beschreibung: Two molecular mechanisms of T cell-mediated cytotoxicity, one perforin-based, the other Fas-based, have been demonstrated. To determine the extent of their contribution to T cell-mediated cytotoxicity, a range of effector cells from normal control or perforin-deficient mice were tested against a panel of target cells with various levels of Fas expression. All cytotoxicity observed was due to either of these mechanisms, and no third mechanism was detected. Thus, the perforin- and Fas-based mechanisms may account for all T cell-mediated cytotoxicity in short-term in vitro assays.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kagi, D -- Vignaux, F -- Ledermann, B -- Burki, K -- Depraetere, V -- Nagata, S -- Hengartner, H -- Golstein, P -- New York, N.Y. -- Science. 1994 Jul 22;265(5171):528-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7518614" target="_blank"〉PubMed〈/a〉

    Rescue of T cell-specific V(D)J recombination in SCID mice by DNA-damaging agents (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-10-21
    Beschreibung: Assembly of antigen receptor V (variable), D (diversity), and J (joining) gene segments requires lymphocyte-specific genes and ubiquitous DNA repair activities. Severe combined immunodeficient (SCID) mice are defective in general double-strand (ds) DNA break repair and V(D)J coding joint formation, resulting in arrested lymphocyte development. A single treatment of newborn SCID mice with DNA-damaging agents restored functional, diverse, T cell receptor beta chain coding joints, as well as development and expansion of thymocytes expressing both CD4 and CD8 coreceptors, but did not promote B cell development. Thymic lymphoma developed in all mice treated with DNA-damaging agents, suggesting an interrelation between V(D)J recombination, dsDNA break repair, and lymphomagenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Danska, J S -- Pflumio, F -- Williams, C J -- Huner, O -- Dick, J E -- Guidos, C J -- New York, N.Y. -- Science. 1994 Oct 21;266(5184):450-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Surgical Research, Hospital for Sick Children Research Institute, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7524150" target="_blank"〉PubMed〈/a〉

    Enhanced aggressive behavior in mice lacking 5-HT1B receptor (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-23
    Beschreibung: The neuromodulator serotonin (5-hydroxytryptamine, 5-HT) has been associated with mood disorders such as depression, anxiety, and impulsive violence. To define the contribution of 5-HT receptor subtypes to behavior, mutant mice lacking the 5-HT1B receptor were generated by homologous recombination. These mice did not exhibit any obvious developmental or behavioral defects. However, the hyperlocomotor effect of the 5-HT1A/1B agonist RU24969 was absent in mutant mice, indicating that this effect is mediated by 5-HT1B receptors. Moreover, when confronted with an intruder, mutant mice attacked the intruder faster and more intensely than did wild-type mice, suggesting the participation of 5-HT1B receptors in aggressive behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saudou, F -- Amara, D A -- Dierich, A -- LeMeur, M -- Ramboz, S -- Segu, L -- Buhot, M C -- Hen, R -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1875-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, U184 de l'INSERM, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091214" target="_blank"〉PubMed〈/a〉

    p53 status and the efficacy of cancer therapy in vivo (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-04
    Beschreibung: The therapeutic responsiveness of genetically defined tumors expressing or devoid of the p53 tumor suppressor gene was compared in immunocompromised mice. Tumors expressing the p53 gene contained a high proportion of apoptotic cells and typically regressed after treatment with gamma radiation or adriamycin. In contrast, p53-deficient tumors treated with the same regimens continued to enlarge and contained few apoptotic cells. Acquired mutations in p53 were associated with both treatment resistance and relapse in p53-expressing tumors. These results establish that defects in apoptosis, here caused by the inactivation of p53, can produce treatment-resistant tumors and suggest that p53 status may be an important determinant of tumor response to therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lowe, S W -- Bodis, S -- McClatchey, A -- Remington, L -- Ruley, H E -- Fisher, D E -- Housman, D E -- Jacks, T -- 5R27CA17575/CA/NCI NIH HHS/ -- CA14051/CA/NCI NIH HHS/ -- R01CA40602/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Nov 4;266(5186):807-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Cancer Research, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973635" target="_blank"〉PubMed〈/a〉

    Diversity of endogenous epitopes bound to MHC class II molecules limited by invariant chain (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-04
    Beschreibung: The invariant chain (Ii) binds nascent major histocompatibility complex (MHC) class II molecules, blocking peptide binding until the complex dissociates in the endosomes. This may serve to differentiate the MHC class I and II antigen presentation pathways and enable class II molecules to efficiently bind peptides in the endosomes. This hypothesis was addressed by probing spleen cells from a combination of knock-out and transgenic mice with a large panel of T cell hybridomas. The Ii molecule blocked the presentation of a range of endogenously synthesized epitopes, but some epitopes actually required Ii. Thus, the influence of Ii on presentation does not follow simple rules. In addition, mice expressing Ii were not tolerant to epitopes unmasked in its absence, a finding with possible implications for autoimmunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bodmer, H -- Viville, S -- Benoist, C -- Mathis, D -- New York, N.Y. -- Science. 1994 Mar 4;263(5151):1284-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7510069" target="_blank"〉PubMed〈/a〉

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

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

    Beschreibung: The population of the developing world is currently expanding at the unprecedented rate of more than 800 million per decade, and despite anticipated reductions in growth during the 21st century, its size is expected to increase from 4.3 billion today to 10.2 billion in 2100. Past efforts to curb this growth have almost exclusively focused on the implementation of family planning programs to provide contraceptive information, services, and supplies. These programs have been partially successful in reducing birth rates. Further investments in them will have an additional but limited impact on population growth; therefore, other policy options, in particular measures to reduce high demand for births and limit population momentum, are needed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bongaarts, J -- New York, N.Y. -- Science. 1994 Feb 11;263(5148):771-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Division, Population Council, New York, NY 10017.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303293" target="_blank"〉PubMed〈/a〉

    Beschreibung: Deletions and other genome rearrangements can be caused by radiation and are associated with carcinogenesis and inheritable diseases. The pink-eyed unstable (p(un)) mutation in the mouse is caused by a gene duplication and reverts to wild type by deletion of one copy. Reversion events in the mouse embryo were detected as black spots on the fur of the animals or microscopically as partially black hair in a background of colorless hair. The frequency of partially black hair was increased by x-rays at very low doses. A linear dose-response relation was found between 1 and 100 centigray.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schiestl, R H -- Khogali, F -- Carls, N -- ES06593/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1573-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Toxicology, Harvard School of Public Health, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985029" target="_blank"〉PubMed〈/a〉

    Digenic retinitis pigmentosa due to mutations at the unlinked peripherin/RDS and ROM1 loci (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-10
    Beschreibung: In spite of recent advances in identifying genes causing monogenic human disease, very little is known about the genes involved in polygenic disease. Three families were identified with mutations in the unlinked photoreceptor-specific genes ROM1 and peripherin/RDS, in which only double heterozygotes develop retinitis pigmentosa (RP). These findings indicate that the allelic and nonallelic heterogeneity known to be a feature of monogenic RP is complicated further by interactions between unlinked mutations causing digenic RP. Recognition of the inheritance pattern exemplified by these three families might facilitate the identification of other examples of digenic inheritance in human disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kajiwara, K -- Berson, E L -- Dryja, T P -- EY00169/EY/NEI NIH HHS/ -- EY08683/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1604-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Berman-Gund Laboratory for the Study of Retinal Degenerations, Harvard Medical School, Massachusetts Eye and Ear Infirmary, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202715" target="_blank"〉PubMed〈/a〉

    Gem: an induced, immediate early protein belonging to the Ras family (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-07-08
    Beschreibung: A gene encoding a 35-kilodalton guanosine triphosphate (GTP)-binding protein, Gem, was cloned from mitogen-induced human peripheral blood T cells. Gem and Rad, the product of a gene overexpressed in skeletal muscle in individuals with Type II diabetes, constitute a new family of Ras-related GTP-binding proteins. The distinct structural features of this family include the G3 GTP-binding motif, extensive amino- and carboxyl-terminal extensions beyond the Ras-related domain, and a motif that determines membrane association. Gem was transiently expressed in human peripheral blood T cells in response to mitogenic stimulation; the protein was phosphorylated on tyrosine residues and localized to the cytosolic face of the plasma membrane. Deregulated Gem expression prevented proliferation of normal and transformed 3T3 cells. These results suggest that Gem is a regulatory protein, possibly participating in receptor-mediated signal transduction at the plasma membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maguire, J -- Santoro, T -- Jensen, P -- Siebenlist, U -- Yewdell, J -- Kelly, K -- New York, N.Y. -- Science. 1994 Jul 8;265(5169):241-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Pathology, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7912851" target="_blank"〉PubMed〈/a〉

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

    Reconstitution of an operational MHC class II compartment in nonantigen-presenting cells (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-12-02
    Beschreibung: Professional antigen-presenting cells (APCs) have a distinct compartment in which class II molecules are proposed to acquire antigenic peptides. Genetic evidence suggests that human leukocyte antigen (HLA)-DM, an unusual class II molecule, participates in this process. Peptide acquisition was reconstituted in nonprofessional APCs by transfection of class II, invariant chain (li), and H-2M, the murine equivalent of DM. The H-2M heterodimer appeared in an endosomal compartment, not at the cell surface, and the localization was independent of li. The data presented show that H-2M, class II, and li are the minimally required components for efficient formation of stable class II-peptide complexes, and thus for a functional class II compartment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karlsson, L -- Peleraux, A -- Lindstedt, R -- Liljedahl, M -- Peterson, P A -- AI-26610/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1569-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉R.

    Prevention of lipopolysaccharide-induced lethal toxicity by tyrosine kinase inhibitors (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-05-27
    Beschreibung: Septic shock results from excessive stimulation of the host immune system, especially macrophages, by lipopolysaccharide (LPS), or endotoxin, which resides on the outer membrane of bacteria. Protein tyrosine kinase inhibitors of the tyrphostin AG 126 family protect mice against LPS-induced lethal toxicity. The protection correlates with the ability of these agents to block LPS-induced production of tumor necrosis factor alpha (TNF-alpha) and nitric oxide in macrophages as well as LPS-induced production of TNF-alpha in vivo. Furthermore, this inhibitory effect correlated with the potency of AG 126 to block LPS-induced tyrosine phosphorylation of a p42MAPK protein substrate in the murine macrophage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Novogrodsky, A -- Vanichkin, A -- Patya, M -- Gazit, A -- Osherov, N -- Levitzki, A -- New York, N.Y. -- Science. 1994 May 27;264(5163):1319-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Felsenstein Medical Research Center, Petach Tikva, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8191285" target="_blank"〉PubMed〈/a〉

    Activation of the myogenic lineage by MEF2A, a factor that induces and cooperates with MyoD (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-18
    Beschreibung: Muscle enhancer factor-2A (MEF2A), a member of the MADS family, induced myogenic development when ectopically expressed in clones of nonmuscle cells of human clones, a function previously limited to the muscle basic helix-loop-helix (bHLH) proteins. During myogenesis, MEF2A and bHLH proteins cooperatively activate skeletal muscle genes and physically interact through the MADS domain of MEF2A and the three myogenic amino acids of the muscle bHLH proteins. Thus, skeletal myogenesis is mediated by two distinct families of mutually inducible and interactive muscle transcription factors, either of which can initiate the developmental cascade.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaushal, S -- Schneider, J W -- Nadal-Ginard, B -- Mahdavi, V -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1236-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cardiology, Children's Hospital, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973707" target="_blank"〉PubMed〈/a〉

    Biodegradable long-circulating polymeric nanospheres (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-18
    Beschreibung: Injectable nanoparticulate carriers have important potential applications such as site-specific drug delivery or medical imaging. Conventional carriers, however, cannot generally be used because they are eliminated by the reticulo-endothelial system within seconds or minutes after intravenous injection. To address these limitations, monodisperse biodegradable nanospheres were developed from amphiphilic copolymers composed of two biocompatible blocks. The nanospheres exhibited dramatically increased blood circulation times and reduced liver accumulation in mice. Furthermore, they entrapped up to 45 percent by weight of the drug in the dense core in a one-step procedure and could be freeze-dried and easily redispersed without additives in aqueous solutions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gref, R -- Minamitake, Y -- Peracchia, M T -- Trubetskoy, V -- Torchilin, V -- Langer, R -- GM 26698/GM/NIGMS NIH HHS/ -- U01 CA52857/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 18;263(5153):1600-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128245" target="_blank"〉PubMed〈/a〉

    Characterization of type I receptors for transforming growth factor-beta and activin (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-01
    Beschreibung: Transforming growth factor-beta (TGF-beta) and activin exert their effects by binding to heteromeric complexes of type I and type II receptors. The type II receptors for TGF-beta and activin are transmembrane serine-threonine kinases; a series of related receptors, denoted activin receptor-like kinase (ALK) 1 to 5, have recently been identified, and ALK-6 is described here. ALK-5 has been shown to be a functional TGF-beta type I receptor. A systematic analysis revealed that most ALKs formed heteromeric complexes with the type II receptors for TGF-beta and activin after overexpression in COS cells; however, among the six ALKs, only ALK-5 was a functional TGF-beta type I receptor for activation of plasminogen activator inhibitor-1, and only ALK-2 and ALK-4 bound activin with high affinity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉ten Dijke, P -- Yamashita, H -- Ichijo, H -- Franzen, P -- Laiho, M -- Miyazono, K -- Heldin, C H -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):101-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ludwig Institute for Cancer Research, Uppsala, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140412" target="_blank"〉PubMed〈/a〉

    Activation of the sphingomyelin cycle through the low-affinity neurotrophin receptor (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-09
    Beschreibung: The role of the low-affinity neurotrophin receptor (p75NTR) in signal transduction is undefined. Nerve growth factor can activate the sphingomyelin cycle, generating the putative-lipid second messenger ceramide. In T9 glioma cells, addition of a cell-permeable ceramide analog mimicked the effects of nerve growth factor on cell growth inhibition and process formation. This signaling pathway appears to be mediated by p75NTR in T9 cells and NIH 3T3 cells overexpressing p75NTR. Expression of an epidermal growth factor receptor-p75NTR chimera in T9 cells imparted to epidermal growth factor the ability to activate the sphingomyelin cycle. These data demonstrate that p75NTR is capable of signaling independently of the trk neurotrophin receptor (p140trk) and that ceramide may be a mediator in neurotrophin biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dobrowsky, R T -- Werner, M H -- Castellino, A M -- Chao, M V -- Hannun, Y A -- AG05531/AG/NIA NIH HHS/ -- GM43825/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 9;265(5178):1596-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Medicine and Cell Biology, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8079174" target="_blank"〉PubMed〈/a〉

    Linkage analysis of IL4 and other chromosome 5q31.1 markers and total serum immunoglobulin E concentrations (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-05-20
    Beschreibung: Sib-pair analysis of 170 individuals from 11 Amish families revealed evidence for linkage of five markers in chromosome 5q31.1 with a gene controlling total serum immunoglobulin E (IgE) concentration. No linkage was found between these markers and specific IgE antibody concentrations. Analysis of total IgE within a subset of 128 IgE antibody-negative sib pairs confirmed evidence for linkage to 5q31.1, especially to the interleukin-4 gene (IL4). A combination of segregation and maximum likelihood analyses provided further evidence for this linkage. These analyses suggest that IL4 or a nearby gene in 5q31.1 regulates IgE production in a nonantigen-specific (noncognate) fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marsh, D G -- Neely, J D -- Breazeale, D R -- Ghosh, B -- Freidhoff, L R -- Ehrlich-Kautzky, E -- Schou, C -- Krishnaswamy, G -- Beaty, T H -- 1 P41 RR03655/RR/NCRR NIH HHS/ -- AI20059/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 May 20;264(5162):1152-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins Asthma and Allergy Center, School of Medicine, Baltimore, MD 21224.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178175" target="_blank"〉PubMed〈/a〉

    Gene for familial psoriasis susceptibility mapped to the distal end of human chromosome 17q (1994)

    Details
    Publikationsdatum: 1994-05-20
    Beschreibung: A gene involved in psoriasis susceptibility was localized to the distal region of human chromosome 17q as a result of a genome-wide linkage analysis with polymorphic microsatellites and eight multiply affected psoriasis kindreds. In the family which showed the strongest evidence for linkage, the recombination fraction between a psoriasis susceptibility locus and D17S784 was 0.04 with a maximum two-point lod score of 5.33. There was also evidence for genetic heterogeneity and although none of the linked families showed any association with HLA-Cw6, two unlinked families showed weak levels of association. This study demonstrates that in some families, psoriasis susceptibility is due to variation at a single major genetic locus other than the human lymphocyte antigen locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomfohrde, J -- Silverman, A -- Barnes, R -- Fernandez-Vina, M A -- Young, M -- Lory, D -- Morris, L -- Wuepper, K D -- Stastny, P -- Menter, A -- P01-AI2327/AI/NIAID NIH HHS/ -- R01 HL47145/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 May 20;264(5162):1141-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of Texas Southwestern Medical Center, Dallas 75235-8591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178173" target="_blank"〉PubMed〈/a〉

    Long-term behavioral recovery in parkinsonian rats by an HSV vector expressing tyrosine hydroxylase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-25
    Beschreibung: One therapeutic approach to treating Parkinson's disease is to convert endogenous striatal cells into levo-3,4-dihydroxyphenylalanine (L-dopa)-producing cells. A defective herpes simplex virus type 1 vector expressing human tyrosine hydroxylase was delivered into the partially denervated striatum of 6-hydroxydopamine-lesioned rats, used as a model of Parkinson's disease. Efficient behavioral and biochemical recovery was maintained for 1 year after gene transfer. Biochemical recovery included increases in both striatal tyrosine hydroxylase enzyme activity and in extracellular dopamine concentrations. Persistence of human tyrosine hydroxylase was revealed by expression of RNA and immunoreactivity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2638002/" 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/PMC2638002/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉During, M J -- Naegele, J R -- O'Malley, K L -- Geller, A I -- EY09749/EY/NEI NIH HHS/ -- NS06208/NS/NINDS NIH HHS/ -- NS28227/NS/NINDS NIH HHS/ -- R01 NS034025/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Nov 25;266(5189):1399-403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, Yale University School of Medicine, New Haven, CT 06510.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7669103" target="_blank"〉PubMed〈/a〉

    Efficient neutralization of primary isolates of HIV-1 by a recombinant human monoclonal antibody (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-11
    Beschreibung: The ability of antibodies to neutralize diverse primary isolates of human immunodeficiency virus-type 1 in vitro has been questioned, with implications for the likely efficacy of vaccines. A recombinant human antibody to envelope glycoprotein gp120 was generated and used to show that primary isolates are not refractory to antibody neutralization. The recombinant antibody neutralized more than 75 percent of the primary isolates tested at concentrations that could be achieved by passive immunization, for example, to interrupt maternal-fetal transmission of virus. The broad specificity and efficacy of the antibody implies the conservation of a structural feature on gp120, which could be important in vaccine design.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burton, D R -- Pyati, J -- Koduri, R -- Sharp, S J -- Thornton, G B -- Parren, P W -- Sawyer, L S -- Hendry, R M -- Dunlop, N -- Nara, P L -- AI27742/AI/NIAID NIH HHS/ -- AI33292/AI/NIAID NIH HHS/ -- AI35168/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1024-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973652" target="_blank"〉PubMed〈/a〉

    Rapid induction of Alzheimer A beta amyloid formation by zinc (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-02
    Beschreibung: A beta 1-40, a major component of Alzheimer's disease cerebral amyloid, is present in the cerebrospinal fluid and remains relatively soluble at high concentrations (less than or equal to 3.7 mM). Thus, physiological factors which induce A beta amyloid formation could provide clues to the pathogenesis of the disease. It has been shown that human A beta specifically and saturably binds zinc. Here, concentrations of zinc above 300 nM rapidly destabilized human A beta 1-40 solutions, inducing tinctorial amyloid formation. However, rat A beta 1-40 binds zinc less avidly and is immune to these effects, perhaps explaining the scarcity with which these animals form cerebral A beta amyloid. These data suggest a role for cerebral zinc metabolism in the neuropathogenesis of Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bush, A I -- Pettingell, W H -- Multhaup, G -- d Paradis, M -- Vonsattel, J P -- Gusella, J F -- Beyreuther, K -- Masters, C L -- Tanzi, R E -- R01 AG11899-01/AG/NIA NIH HHS/ -- R01 NS30428-03/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1464-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics and Aging, Massachusetts General Hospital, Boston.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073293" target="_blank"〉PubMed〈/a〉

    The mating of a fly (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-17
    Beschreibung: Courtship in Drosophila is influenced by a wide variety of genes, in that many different kinds of pleiotropic mutations lead to defective courtship. This may seem to be a truism, but the broad temporal and spatial expression of most of the fly's "neuro genes" makes it difficult to exclude elements of such genes' actions as materially underlying reproductive behavior. "Courtship genes" that seem to play more particular roles were originally identified as sensory, learning, or rhythm mutations; their reproductive abnormalities have been especially informative for revealing components of male or female actions that might otherwise have gone unnoticed. Further behavioral mutations seemed originally to be courtship-specific, turned out not to have that property, and have led to a broadened perspective on the nature and action of Drosophila's sex-determination genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, J C -- GM-21473/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 17;264(5166):1702-14.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Brandeis University, Waltham, MA 02254-9110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8209251" target="_blank"〉PubMed〈/a〉

    Human severe combined immunodeficiency due to a defect in ZAP-70, a T cell tyrosine kinase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-10
    Beschreibung: A homozygous mutation in the kinase domain of ZAP-70, a T cell receptor-associated protein tyrosine kinase, produced a distinctive form of human severe combined immunodeficiency. Manifestations of this disorder included profound immunodeficiency, absence of peripheral CD8+ T cells, and abundant peripheral CD4+ T cells that were refractory to T cell receptor-mediated activation. These findings demonstrate that ZAP-70 is essential for human T cell function and suggest that CD4+ and CD8+ T cells depend on different intracellular signaling pathways to support their development or survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elder, M E -- Lin, D -- Clever, J -- Chan, A C -- Hope, T J -- Weiss, A -- Parslow, T G -- AI29313/AI/NIAID NIH HHS/ -- GM43574/GM/NIGMS NIH HHS/ -- RR01271/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1596-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of California, San Francisco 94143-0110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202712" target="_blank"〉PubMed〈/a〉
