    Prevention of chemotherapy-induced alopecia in rats by CDK inhibitors (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-01-06
    Description: Most traditional cytotoxic anticancer agents ablate the rapidly dividing epithelium of the hair follicle and induce alopecia (hair loss). Inhibition of cyclin-dependent kinase 2 (CDK2), a positive regulator of eukaryotic cell cycle progression, may represent a therapeutic strategy for prevention of chemotherapy-induced alopecia (CIA) by arresting the cell cycle and reducing the sensitivity of the epithelium to many cell cycle-active antitumor agents. Potent small-molecule inhibitors of CDK2 were developed using structure-based methods. Topical application of these compounds in a neonatal rat model of CIA reduced hair loss at the site of application in 33 to 50% of the animals. Thus, inhibition of CDK2 represents a potentially useful approach for the prevention of CIA in cancer patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S T -- Benson, B G -- Bramson, H N -- Chapman, D E -- Dickerson, S H -- Dold, K M -- Eberwein, D J -- Edelstein, M -- Frye, S V -- Gampe Jr, R T -- Griffin, R J -- Harris, P A -- Hassell, A M -- Holmes, W D -- Hunter, R N -- Knick, V B -- Lackey, K -- Lovejoy, B -- Luzzio, M J -- Murray, D -- Parker, P -- Rocque, W J -- Shewchuk, L -- Veal, J M -- Walker, D H -- Kuyper, L F -- New York, N.Y. -- Science. 2001 Jan 5;291(5501):134-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cancer Biology, Glaxo Wellcome Research and Development, Research Triangle Park, NC 27709, USA. std41085@glaxowellcome.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11141566" target="_blank"〉PubMed〈/a〉

    No major schizophrenia locus detected on chromosome 1q in a large multicenter sample (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-04-27
    Description: Reports of substantial evidence for genetic linkage of schizophrenia to chromosome 1q were evaluated by genotyping 16 DNA markers across 107 centimorgans of this chromosome in a multicenter sample of 779 informative schizophrenia pedigrees. No significant evidence was observed for such linkage, nor for heterogeneity in allele sharing among the eight individual samples. Separate analyses of European-origin families, recessive models of inheritance, and families with larger numbers of affected cases also failed to produce significant evidence for linkage. If schizophrenia susceptibility genes are present on chromosome 1q, their population-wide genetic effects are likely to be small.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levinson, Douglas F -- Holmans, Peter A -- Laurent, Claudine -- Riley, Brien -- Pulver, Ann E -- Gejman, Pablo V -- Schwab, Sibylle G -- Williams, Nigel M -- Owen, Michael J -- Wildenauer, Dieter B -- Sanders, Alan R -- Nestadt, Gerald -- Mowry, Bryan J -- Wormley, Brandon -- Bauche, Stephanie -- Soubigou, Stephane -- Ribble, Robert -- Nertney, Deborah A -- Liang, Kung Yee -- Martinolich, Laura -- Maier, Wolfgang -- Norton, Nadine -- Williams, Hywel -- Albus, Margot -- Carpenter, Eric B -- DeMarchi, Nicola -- Ewen-White, Kelly R -- Walsh, Dermot -- Jay, Maurice -- Deleuze, Jean-Francois -- O'Neill, F Anthony -- Papadimitriou, George -- Weilbaecher, Ann -- Lerer, Bernard -- O'Donovan, Michael C -- Dikeos, Dimitris -- Silverman, Jeremy M -- Kendler, Kenneth S -- Mallet, Jacques -- Crowe, Raymond R -- Walters, Marilyn -- G9309834/Medical Research Council/United Kingdom -- G9810900/Medical Research Council/United Kingdom -- K24-MH64197/MH/NIMH NIH HHS/ -- KO2-01207/PHS HHS/ -- MH 41953/MH/NIMH NIH HHS/ -- MH 45390/MH/NIMH NIH HHS/ -- MH 52537/MH/NIMH NIH HHS/ -- MH61602/MH/NIMH NIH HHS/ -- R01-MH57314/MH/NIMH NIH HHS/ -- U01 MH46289/MH/NIMH NIH HHS/ -- U01 MH46318/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2002 Apr 26;296(5568):739-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Pennsylvania, Philadelphia, PA 19104, USA. dfl@mail.med.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11976456" target="_blank"〉PubMed〈/a〉

    Contribution of increasing CO2 and climate to carbon storage by ecosystems in the United States (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-03-17
    Description: The effects of increasing carbon dioxide (CO2) and climate on net carbon storage in terrestrial ecosystems of the conterminous United States for the period 1895-1993 were modeled with new, detailed historical climate information. For the period 1980-1993, results from an ensemble of three models agree within 25%, simulating a land carbon sink from CO2 and climate effects of 0.08 gigaton of carbon per year. The best estimates of the total sink from inventory data are about three times larger, suggesting that processes such as regrowth on abandoned agricultural land or in forests harvested before 1980 have effects as large as or larger than the direct effects of CO2 and climate. The modeled sink varies by about 100% from year to year as a result of climate variability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schimel, D -- Melillo, J -- Tian, H -- McGuire, A D -- Kicklighter, D -- Kittel, T -- Rosenbloom, N -- Running, S -- Thornton, P -- Ojima, D -- Parton, W -- Kelly, R -- Sykes, M -- Neilson, R -- Rizzo, B -- New York, N.Y. -- Science. 2000 Mar 17;287(5460):2004-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institute for Biogeochemistry, Postfach 10 01 64, D-07701 Jena, Germany. dschimel@bgc-jena.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10720324" target="_blank"〉PubMed〈/a〉

    Inactivation of TNF signaling by rationally designed dominant-negative TNF variants (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-27
    Description: Tumor necrosis factor (TNF) is a key regulator of inflammatory responses and has been implicated in many pathological conditions. We used structure-based design to engineer variant TNF proteins that rapidly form heterotrimers with native TNF to give complexes that neither bind to nor stimulate signaling through TNF receptors. Thus, TNF is inactivated by sequestration. Dominant-negative TNFs represent a possible approach to anti-inflammatory biotherapeutics, and experiments in animal models show that the strategy can attenuate TNF-mediated pathology. Similar rational design could be used to engineer inhibitors of additional TNF superfamily cytokines as well as other multimeric ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steed, Paul M -- Tansey, Malu G -- Zalevsky, Jonathan -- Zhukovsky, Eugene A -- Desjarlais, John R -- Szymkowski, David E -- Abbott, Christina -- Carmichael, David -- Chan, Cheryl -- Cherry, Lisa -- Cheung, Peter -- Chirino, Arthur J -- Chung, Hyo H -- Doberstein, Stephen K -- Eivazi, Araz -- Filikov, Anton V -- Gao, Sarah X -- Hubert, Rene S -- Hwang, Marian -- Hyun, Linus -- Kashi, Sandhya -- Kim, Alice -- Kim, Esther -- Kung, James -- Martinez, Sabrina P -- Muchhal, Umesh S -- Nguyen, Duc-Hanh T -- O'Brien, Christopher -- O'Keefe, Donald -- Singer, Karen -- Vafa, Omid -- Vielmetter, Jost -- Yoder, Sean C -- Dahiyat, Bassil I -- New York, N.Y. -- Science. 2003 Sep 26;301(5641):1895-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Xencor, 111 West Lemon Avenue, Monrovia, CA 91016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14512626" target="_blank"〉PubMed〈/a〉

    The influence of the proinflammatory cytokine, osteopontin, on autoimmune demyelinating disease (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-11-27
    Description: Multiple sclerosis is a demyelinating disease, characterized by inflammation in the brain and spinal cord, possibly due to autoimmunity. Large-scale sequencing of cDNA libraries, derived from plaques dissected from brains of patients with multiple sclerosis (MS), indicated an abundance of transcripts for osteopontin (OPN). Microarray analysis of spinal cords from rats paralyzed by experimental autoimmune encephalomyelitis (EAE), a model of MS, also revealed increased OPN transcripts. Osteopontin-deficient mice were resistant to progressive EAE and had frequent remissions, and myelin-reactive T cells in OPN-/- mice produced more interleukin 10 and less interferon-gamma than in OPN+/+ mice. Osteopontin thus appears to regulate T helper cell-1 (TH1)-mediated demyelinating disease, and it may offer a potential target in blocking development of progressive MS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chabas, D -- Baranzini, S E -- Mitchell, D -- Bernard, C C -- Rittling, S R -- Denhardt, D T -- Sobel, R A -- Lock, C -- Karpuj, M -- Pedotti, R -- Heller, R -- Oksenberg, J R -- Steinman, L -- New York, N.Y. -- Science. 2001 Nov 23;294(5547):1731-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology and Neurological Sciences, Beckman Center for Molecular Medicine, B002, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11721059" target="_blank"〉PubMed〈/a〉

    Identification of ubiquitin ligases required for skeletal muscle atrophy (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-10-27
    Description: Skeletal muscle adapts to decreases in activity and load by undergoing atrophy. To identify candidate molecular mediators of muscle atrophy, we performed transcript profiling. Although many genes were up-regulated in a single rat model of atrophy, only a small subset was universal in all atrophy models. Two of these genes encode ubiquitin ligases: Muscle RING Finger 1 (MuRF1), and a gene we designate Muscle Atrophy F-box (MAFbx), the latter being a member of the SCF family of E3 ubiquitin ligases. Overexpression of MAFbx in myotubes produced atrophy, whereas mice deficient in either MAFbx or MuRF1 were found to be resistant to atrophy. These proteins are potential drug targets for the treatment of muscle atrophy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bodine, S C -- Latres, E -- Baumhueter, S -- Lai, V K -- Nunez, L -- Clarke, B A -- Poueymirou, W T -- Panaro, F J -- Na, E -- Dharmarajan, K -- Pan, Z Q -- Valenzuela, D M -- DeChiara, T M -- Stitt, T N -- Yancopoulos, G D -- Glass, D J -- New York, N.Y. -- Science. 2001 Nov 23;294(5547):1704-8.

    Asparagine hydroxylation of the HIF transactivation domain a hypoxic switch (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-02-02
    Description: The hypoxia-inducible factors (HIFs) 1alpha and 2alpha are key mammalian transcription factors that exhibit dramatic increases in both protein stability and intrinsic transcriptional potency during low-oxygen stress. This increased stability is due to the absence of proline hydroxylation, which in normoxia promotes binding of HIF to the von Hippel-Lindau (VHL tumor suppressor) ubiquitin ligase. We now show that hypoxic induction of the COOH-terminal transactivation domain (CAD) of HIF occurs through abrogation of hydroxylation of a conserved asparagine in the CAD. Inhibitors of Fe(II)- and 2-oxoglutarate-dependent dioxygenases prevented hydroxylation of the Asn, thus allowing the CAD to interact with the p300 transcription coactivator. Replacement of the conserved Asn by Ala resulted in constitutive p300 interaction and strong transcriptional activity. Full induction of HIF-1alpha and -2alpha, therefore, relies on the abrogation of both Pro and Asn hydroxylation, which during normoxia occur at the degradation and COOH-terminal transactivation domains, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lando, David -- Peet, Daniel J -- Whelan, Dean A -- Gorman, Jeffrey J -- Whitelaw, Murray L -- New York, N.Y. -- Science. 2002 Feb 1;295(5556):858-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biosciences (Biochemistry), Adelaide University, SA 5005, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11823643" target="_blank"〉PubMed〈/a〉

    The structure and receptor binding properties of the 1918 influenza hemagglutinin (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-07
    Description: The 1918 influenza pandemic resulted in about 20 million deaths. This enormous impact, coupled with renewed interest in emerging infections, makes characterization of the virus involved a priority. Receptor binding, the initial event in virus infection, is a major determinant of virus transmissibility that, for influenza viruses, is mediated by the hemagglutinin (HA) membrane glycoprotein. We have determined the crystal structures of the HA from the 1918 virus and two closely related HAs in complex with receptor analogs. They explain how the 1918 HA, while retaining receptor binding site amino acids characteristic of an avian precursor HA, is able to bind human receptors and how, as a consequence, the virus was able to spread in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gamblin, S J -- Haire, L F -- Russell, R J -- Stevens, D J -- Xiao, B -- Ha, Y -- Vasisht, N -- Steinhauer, D A -- Daniels, R S -- Elliot, A -- Wiley, D C -- Skehel, J J -- AI-13654/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Mar 19;303(5665):1838-42.

    Description: The structure of an RNA polymerase II-transcribing complex has been determined in the posttranslocation state, with a vacancy at the growing end of the RNA-DNA hybrid helix. At the opposite end of the hybrid helix, the RNA separates from the template DNA. This separation of nucleic acid strands is brought about by interaction with a set of proteins loops in a strand/loop network. Formation of the network must occur in the transition from abortive initiation to promoter escape.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westover, Kenneth D -- Bushnell, David A -- Kornberg, Roger D -- GM49985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):1014-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305-5126, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963331" target="_blank"〉PubMed〈/a〉
