    Continuous in vitro evolution of catalytic function (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-04-25
    Description: A population of RNA molecules that catalyze the template-directed ligation of RNA substrates was made to evolve in a continuous manner in the test tube. A simple serial transfer procedure was used to achieve approximately 300 successive rounds of catalysis and selective amplification in 52 hours. During this time, the population size was maintained against an overall dilution of 3 x 10(298). Both the catalytic rate and amplification rate of the RNAs improved substantially as a consequence of mutations that accumulated during the evolution process. Continuous in vitro evolution makes it possible to maintain laboratory "cultures" of catalytic molecules that can be perpetuated indefinitely.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wright, M C -- Joyce, G F -- New York, N.Y. -- Science. 1997 Apr 25;276(5312):614-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, The Skaggs Institute for Chemical Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9110984" target="_blank"〉PubMed〈/a〉

    Murine model of Niemann-Pick C disease: mutation in a cholesterol homeostasis gene (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-11
    Description: An integrated human-mouse positional candidate approach was used to identify the gene responsible for the phenotypes observed in a mouse model of Niemann-Pick type C (NP-C) disease. The predicted murine NPC1 protein has sequence homology to the putative transmembrane domains of the Hedgehog signaling molecule Patched, to the cholesterol-sensing regions of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase and SREBP cleavage-activating protein (SCAP), and to the NPC1 orthologs identified in human, the nematode Caenorhabditis elegans, and the yeast Saccharomyces cerevisiae. The mouse model may provide an important resource for studying the role of NPC1 in cholesterol homeostasis and neurodegeneration and for assessing the efficacy of new drugs for NP-C disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loftus, S K -- Morris, J A -- Carstea, E D -- Gu, J Z -- Cummings, C -- Brown, A -- Ellison, J -- Ohno, K -- Rosenfeld, M A -- Tagle, D A -- Pentchev, P G -- Pavan, W J -- New York, N.Y. -- Science. 1997 Jul 11;277(5323):232-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetic Disease Research, National Human Genome Research Institute, National Institutes of Health (NIH), Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9211850" target="_blank"〉PubMed〈/a〉

    Nonsyndromic deafness DFNA1 associated with mutation of a human homolog of the Drosophila gene diaphanous (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-21
    Description: The gene responsible for autosomal dominant, fully penetrant, nonsyndromic sensorineural progressive hearing loss in a large Costa Rican kindred was previously localized to chromosome 5q31 and named DFNA1. Deafness in the family is associated with a protein-truncating mutation in a human homolog of the Drosophila gene diaphanous. The truncation is caused by a single nucleotide substitution in a splice donor, leading to a four-base pair insertion in messenger RNA and a frameshift. The diaphanous protein is a profilin ligand and target of Rho that regulates polymerization of actin, the major component of the cytoskeleton of hair cells of the inner ear.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lynch, E D -- Lee, M K -- Morrow, J E -- Welcsh, P L -- Leon, P E -- King, M C -- R01-DC01076/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 14;278(5341):1315-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Washington, Seattle, WA 98195, USA. eric@lynch.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9360932" target="_blank"〉PubMed〈/a〉

    Somatic frameshift mutations in the BAX gene in colon cancers of the microsatellite mutator phenotype (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-14
    Description: Cancers of the microsatellite mutator phenotype (MMP) show exaggerated genomic instability at simple repeat sequences. More than 50 percent (21 out of 41) of human MMP+ colon adenocarcinomas examined were found to have frameshift mutations in a tract of eight deoxyguanosines [(G)8] within BAX, a gene that promotes apoptosis. These mutations were absent in MMP- tumors and were significantly less frequent in (G)8 repeats from other genes. Frameshift mutations were present in both BAX alleles in some MMP+ colon tumor cell lines and in primary tumors. These results suggest that inactivating BAX mutations are selected for during the progression of colorectal MMP+ tumors and that the wild-type BAX gene plays a suppressor role in a p53-independent pathway for colorectal carcinogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rampino, N -- Yamamoto, H -- Ionov, Y -- Li, Y -- Sawai, H -- Reed, J C -- Perucho, M -- CA38579/CA/NCI NIH HHS/ -- CA63585/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Feb 14;275(5302):967-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Burnham Institute, La Jolla Cancer Research Center, 10901 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9020077" target="_blank"〉PubMed〈/a〉

    Bimolecular exon ligation by the human spliceosome (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-13
    Description: Intron excision is an essential step in eukaryotic gene expression, but the molecular mechanisms by which the spliceosome accurately identifies splice sites in nuclear precursors to messenger RNAs (pre-mRNAs) are not well understood. A bimolecular assay for the second step of splicing has now revealed that exon ligation by the human spliceosome does not require covalent attachment of a 3' splice site to the branch site. Furthermore, accurate definition of the 3' splice site in this system is independent of either a covalently attached polypyrimidine tract or specific 3' exon sequences. Rather, in this system 3' splice site selection apparently occurs with a 5' --〉 3' directionality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, K -- Moore, M J -- GM53007/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1712-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉W.
