    Beschreibung: A blood donor infected with human immunodeficiency virus-type 1 (HIV-1) and a cohort of six blood or blood product recipients infected from this donor remain free of HIV-1-related disease with stable and normal CD4 lymphocyte counts 10 to 14 years after infection. HIV-1 sequences from either virus isolates or patient peripheral blood mononuclear cells had similar deletions in the nef gene and in the region of overlap of nef and the U3 region of the long terminal repeat (LTR). Full-length sequencing of one isolate genome and amplification of selected HIV-1 genome regions from other cohort members revealed no other abnormalities of obvious functional significance. These data show that survival after HIV infection can be determined by the HIV genome and support the importance of nef or the U3 region of the LTR in determining the pathogenicity of HIV-1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deacon, N J -- Tsykin, A -- Solomon, A -- Smith, K -- Ludford-Menting, M -- Hooker, D J -- McPhee, D A -- Greenway, A L -- Ellett, A -- Chatfield, C -- Lawson, V A -- Crowe, S -- Maerz, A -- Sonza, S -- Learmont, J -- Sullivan, J S -- Cunningham, A -- Dwyer, D -- Dowton, D -- Mills, J -- New York, N.Y. -- Science. 1995 Nov 10;270(5238):988-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉AIDS Molecular Biology Unit, Macfarlane Burnet Centre for Medical Research, Fairfield, Victoria, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481804" target="_blank"〉PubMed〈/a〉

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

    Beschreibung: A candidate gene for the chromosome 1 Alzheimer's disease (AD) locus was identified (STM2). The predicted amino acid sequence for STM2 is homologous to that of the recently cloned chromosome 14 AD gene (S182). A point mutation in STM2, resulting in the substitution of an isoleucine for an asparagine (N141l), was identified in affected people from Volga German AD kindreds. This N141l mutation occurs at an amino acid residue that is conserved in human S182 and in the mouse S182 homolog. The presence of missense mutations in AD subjects in two highly similar genes strongly supports the hypothesis that mutations in both are pathogenic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy-Lahad, E -- Wasco, W -- Poorkaj, P -- Romano, D M -- Oshima, J -- Pettingell, W H -- Yu, C E -- Jondro, P D -- Schmidt, S D -- Wang, K -- AG0513C/AG/NIA NIH HHS/ -- R01-AG11762/AG/NIA NIH HHS/ -- R01-AG11899/AG/NIA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1995 Aug 18;269(5226):973-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geriatric Research Education, and Clinical Center (182B), Veterans Affairs Medical Center, Seattle, WA 98108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7638622" target="_blank"〉PubMed〈/a〉

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

    Beschreibung: An approach for genome analysis based on sequencing and assembly of unselected pieces of DNA from the whole chromosome has been applied to obtain the complete nucleotide sequence (1,830,137 base pairs) of the genome from the bacterium Haemophilus influenzae Rd. This approach eliminates the need for initial mapping efforts and is therefore applicable to the vast array of microbial species for which genome maps are unavailable. The H. influenzae Rd genome sequence (Genome Sequence DataBase accession number L42023) represents the only complete genome sequence from a free-living organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fleischmann, R D -- Adams, M D -- White, O -- Clayton, R A -- Kirkness, E F -- Kerlavage, A R -- Bult, C J -- Tomb, J F -- Dougherty, B A -- Merrick, J M -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):496-512.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7542800" target="_blank"〉PubMed〈/a〉

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

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

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

    Beschreibung: The Tat protein of bovine immunodeficiency virus (BIV) binds to its target RNA, TAR, and activates transcription. A 14-amino acid arginine-rich peptide corresponding to the RNA-binding domain of BIV Tat binds specifically to BIV TAR, and biochemical and in vivo experiments have identified the amino acids and nucleotides required for binding. The solution structure of the RNA-peptide complex has now been determined by nuclear magnetic resonance spectroscopy. TAR forms a virtually continuous A-form helix with two unstacked bulged nucleotides. The peptide adopts a beta-turn conformation and sits in the major groove of the RNA. Specific contacts are apparent between critical amino acids in the peptide and bases and phosphates in the RNA. The structure is consistent with all biochemical data and demonstrates ways in which proteins can recognize the major groove of RNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Puglisi, J D -- Chen, L -- Blanchard, S -- Frankel, A D -- AI08591/AI/NIAID NIH HHS/ -- AI29135/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 17;270(5239):1200-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California, Santa Cruz 95064, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502045" target="_blank"〉PubMed〈/a〉

    Beschreibung: The arginine residue at position 586 of the GluR-B subunit renders heteromeric alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA)-sensitive glutamate receptor channels impermeable to calcium. The codon for this arginine is introduced at the precursor messenger RNA (pre-mRNA) stage by site-selective adenosine editing of a glutamine codon. Heterozygous mice engineered by gene targeting to harbor an editing-incompetent GluR-B allele synthesized unedited GluR-B subunits and, in principal neurons and interneurons, expressed AMPA receptors with increased calcium permeability. These mice developed seizures and died by 3 weeks of age, showing that GluR-B pre-mRNA editing is essential for brain function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brusa, R -- Zimmermann, F -- Koh, D S -- Feldmeyer, D -- Gass, P -- Seeburg, P H -- Sprengel, R -- New York, N.Y. -- Science. 1995 Dec 8;270(5242):1677-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Neuroendocrinology, University of Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502080" target="_blank"〉PubMed〈/a〉
