    Functional characterization of the S. cerevisiae genome by gene deletion and parallel analysis (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-08-07
    Description: The functions of many open reading frames (ORFs) identified in genome-sequencing projects are unknown. New, whole-genome approaches are required to systematically determine their function. A total of 6925 Saccharomyces cerevisiae strains were constructed, by a high-throughput strategy, each with a precise deletion of one of 2026 ORFs (more than one-third of the ORFs in the genome). Of the deleted ORFs, 17 percent were essential for viability in rich medium. The phenotypes of more than 500 deletion strains were assayed in parallel. Of the deletion strains, 40 percent showed quantitative growth defects in either rich or minimal medium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winzeler, E A -- Shoemaker, D D -- Astromoff, A -- Liang, H -- Anderson, K -- Andre, B -- Bangham, R -- Benito, R -- Boeke, J D -- Bussey, H -- Chu, A M -- Connelly, C -- Davis, K -- Dietrich, F -- Dow, S W -- El Bakkoury, M -- Foury, F -- Friend, S H -- Gentalen, E -- Giaever, G -- Hegemann, J H -- Jones, T -- Laub, M -- Liao, H -- Liebundguth, N -- Lockhart, D J -- Lucau-Danila, A -- Lussier, M -- M'Rabet, N -- Menard, P -- Mittmann, M -- Pai, C -- Rebischung, C -- Revuelta, J L -- Riles, L -- Roberts, C J -- Ross-MacDonald, P -- Scherens, B -- Snyder, M -- Sookhai-Mahadeo, S -- Storms, R K -- Veronneau, S -- Voet, M -- Volckaert, G -- Ward, T R -- Wysocki, R -- Yen, G S -- Yu, K -- Zimmermann, K -- Philippsen, P -- Johnston, M -- Davis, R W -- HG00185-02/HG/NHGRI NIH HHS/ -- HG01627/HG/NHGRI NIH HHS/ -- HG01633/HG/NHGRI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1999 Aug 6;285(5429):901-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford University School of Medicine, Stanford, CA 94305-5307, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10436161" target="_blank"〉PubMed〈/a〉

    Mitotic misregulation and human aging (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-03-31
    Description: Messenger RNA levels were measured in actively dividing fibroblasts isolated from young, middle-age, and old-age humans and humans with progeria, a rare genetic disorder characterized by accelerated aging. Genes whose expression is associated with age-related phenotypes and diseases were identified. The data also suggest that an underlying mechanism of the aging process involves increasing errors in the mitotic machinery of dividing cells in the postreproductive stage of life. We propose that this dysfunction leads to chromosomal pathologies that result in misregulation of genes involved in the aging process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ly, D H -- Lockhart, D J -- Lerner, R A -- Schultz, P G -- New York, N.Y. -- Science. 2000 Mar 31;287(5462):2486-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and 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/10741968" target="_blank"〉PubMed〈/a〉

    Exploiting chemical libraries, structure, and genomics in the search for kinase inhibitors (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-07-24
    Description: Selective protein kinase inhibitors were developed on the basis of the unexpected binding mode of 2,6,9-trisubstituted purines to the adenosine triphosphate-binding site of the human cyclin-dependent kinase 2 (CDK2). By iterating chemical library synthesis and biological screening, potent inhibitors of the human CDK2-cyclin A kinase complex and of Saccharomyces cerevisiae Cdc28p were identified. The structural basis for the binding affinity and selectivity was determined by analysis of a three-dimensional crystal structure of a CDK2-inhibitor complex. The cellular effects of these compounds were characterized in mammalian cells and yeast. In the latter case the effects were characterized on a genome-wide scale by monitoring changes in messenger RNA levels in treated cells with high-density oligonucleotide probe arrays. Purine libraries could provide useful tools for analyzing a variety of signaling and regulatory pathways and may lead to the development of new therapeutics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, N S -- Wodicka, L -- Thunnissen, A M -- Norman, T C -- Kwon, S -- Espinoza, F H -- Morgan, D O -- Barnes, G -- LeClerc, S -- Meijer, L -- Kim, S H -- Lockhart, D J -- Schultz, P G -- New York, N.Y. -- Science. 1998 Jul 24;281(5376):533-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9677190" target="_blank"〉PubMed〈/a〉

    Replication dynamics of the yeast genome (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-10-06
    Description: Oligonucleotide microarrays were used to map the detailed topography of chromosome replication in the budding yeast Saccharomyces cerevisiae. The times of replication of thousands of sites across the genome were determined by hybridizing replicated and unreplicated DNAs, isolated at different times in S phase, to the microarrays. Origin activations take place continuously throughout S phase but with most firings near mid-S phase. Rates of replication fork movement vary greatly from region to region in the genome. The two ends of each of the 16 chromosomes are highly correlated in their times of replication. This microarray approach is readily applicable to other organisms, including humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raghuraman, M K -- Winzeler, E A -- Collingwood, D -- Hunt, S -- Wodicka, L -- Conway, A -- Lockhart, D J -- Davis, R W -- Brewer, B J -- Fangman, W L -- New York, N.Y. -- Science. 2001 Oct 5;294(5540):115-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Department of Mathematics, University of Washington, Seattle, WA 98195, USA. raghu@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11588253" target="_blank"〉PubMed〈/a〉

    Internal stark effect measurement of the electric field at the amino terminus of an alpha helix (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-08-14
    Description: The strengths of electrostatic interactions in biological molecules are difficult to calculate or predict because they occur in complicated, inhomogeneous environments. The electric field at the amino terminus of an alpha helix in water has been determined by measuring the shift in the absorption band for a covalently attached, neutral probe molecule with an electric dipole moment difference between the ground and excited electronic states (an internal Stark effect). The field at the interface between the helix and the solvent is found to be an order of magnitude stronger than expected from the dielectric properties of bulk water. Furthermore, although the total electric dipole moment of the helix increases with length, the electric field at the amino terminus does not.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lockhart, D J -- Kim, P S -- New York, N.Y. -- Science. 1992 Aug 14;257(5072):947-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Nine Cambridge Center 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1502559" target="_blank"〉PubMed〈/a〉

    Direct allelic variation scanning of the yeast genome (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-08-26
    Description: As more genomes are sequenced, the identification and characterization of the causes of heritable variation within a species will be increasingly important. It is demonstrated that allelic variation in any two isolates of a species can be scanned, mapped, and scored directly and efficiently without allele-specific polymerase chain reaction, without creating new strains or constructs, and without knowing the specific nature of the variation. A total of 3714 biallelic markers, spaced about every 3.5 kilobases, were identified by analyzing the patterns obtained when total genomic DNA from two different strains of yeast was hybridized to high-density oligonucleotide arrays. The markers were then used to simultaneously map a multidrug-resistance locus and four other loci with high resolution (11 to 64 kilobases).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winzeler, E A -- Richards, D R -- Conway, A R -- Goldstein, A L -- Kalman, S -- McCullough, M J -- McCusker, J H -- Stevens, D A -- Wodicka, L -- Lockhart, D J -- Davis, R W -- 1R01 HG01633/HG/NHGRI NIH HHS/ -- HG00185-01/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1998 Aug 21;281(5380):1194-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford University School of Medicine, Stanford, CA 94305-5307, USA. winzeler@cmgm.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9712584" target="_blank"〉PubMed〈/a〉

    Electrostatic screening of charge and dipole interactions with the helix backbone (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-09
    Description: Electrostatic interactions in proteins are potentially quite strong, but these interactions are mitigated by the screening effects of water, ions, and nearby protein atoms. The early work of Kirkwood and Westheimer on small organic molecules showed that the extent of the screening may depend on whether charged or dipolar groups are involved. The dielectric and ionic screening of the interactions between the dipolar backbone amide groups of monomeric alpha helices and either (i) solvent-exposed charges or (ii) solvent-exposed dipoles at the amino terminus was measured. The dielectric screening effects are an order of magnitude greater for the backbone-charge interactions than for the backbone-dipole interactions, and the ionic strength dependence is substantially different in the two cases. These results suggest that interactions that involve the dipolar groups of proteins may be relatively more important for stability and function than is generally thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lockhart, D J -- Kim, P S -- New York, N.Y. -- Science. 1993 Apr 9;260(5105):198-202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge Center 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8469972" target="_blank"〉PubMed〈/a〉

    Accessing genetic information with high-density DNA arrays (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-10-25
    Description: Rapid access to genetic information is central to the revolution taking place in molecular genetics. The simultaneous analysis of the entire human mitochondrial genome is described here. DNA arrays containing up to 135,000 probes complementary to the 16.6-kilobase human mitochondrial genome were generated by light-directed chemical synthesis. A two-color labeling scheme was developed that allows simultaneous comparison of a polymorphic target to a reference DNA or RNA. Complete hybridization patterns were revealed in a matter of minutes. Sequence polymorphisms were detected with single-base resolution and unprecedented efficiency. The methods described are generic and can be used to address a variety of questions in molecular genetics including gene expression, genetic linkage, and genetic variability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chee, M -- Yang, R -- Hubbell, E -- Berno, A -- Huang, X C -- Stern, D -- Winkler, J -- Lockhart, D J -- Morris, M S -- Fodor, S P -- 5RO1HG00813/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1996 Oct 25;274(5287):610-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Affymetrix, 3380 Central Expressway, Santa Clara, CA 95051, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8849452" target="_blank"〉PubMed〈/a〉
