    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〉
