    IRS-1-mediated inhibition of insulin receptor tyrosine kinase activity in TNF-alpha- and obesity-induced insulin resistance (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-02-02
    Description: Tumor necrosis factor-alpha (TNF-alpha) is an important mediator of insulin resistance in obesity and diabetes through its ability to decrease the tyrosine kinase activity of the insulin receptor (IR). Treatment of cultured murine adipocytes with TNF-alpha was shown to induce serine phosphorylation of insulin receptor substrate 1 (IRS-1) and convert IRS-1 into an inhibitor of the IR tyrosine kinase activity in vitro. Myeloid 32D cells, which lack endogenous IRS-1, were resistant to TNF-alpha-mediated inhibition of IR signaling, whereas transfected 32D cells that express IRS-1 were very sensitive to this effect of TNF-alpha. An inhibitory form of IRS-1 was observed in muscle and fat tissues from obese rats. These results indicate that TNF-alpha induces insulin resistance through an unexpected action of IRS-1 to attenuate insulin receptor signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hotamisligil, G S -- Peraldi, P -- Budavari, A -- Ellis, R -- White, M F -- Spiegelman, B M -- DK 42539/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1996 Feb 2;271(5249):665-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Biology, Dana-Farber Cancer Institute, Boston, MA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8571133" target="_blank"〉PubMed〈/a〉

    Nuclear accumulation of NFAT4 opposed by the JNK signal transduction pathway (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-12-31
    Description: The nuclear factor of activated T cells (NFAT) group of transcription factors is retained in the cytoplasm of quiescent cells. NFAT activation is mediated in part by induced nuclear import. This process requires calcium-dependent dephosphorylation of NFAT caused by the phosphatase calcineurin. The c-Jun amino-terminal kinase (JNK) phosphorylates NFAT4 on two sites. Mutational removal of the JNK phosphorylation sites caused constitutive nuclear localization of NFAT4. In contrast, JNK activation in calcineurin-stimulated cells caused nuclear exclusion of NFAT4. These findings show that the nuclear accumulation of NFAT4 promoted by calcineurin is opposed by the JNK signal transduction pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chow, C W -- Rincon, M -- Cavanagh, J -- Dickens, M -- Davis, R J -- CA58396/CA/NCI NIH HHS/ -- CA65831/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1638-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Program in Molecular Medicine, Department of Biochemistry and Molecular Biology, University of Massachusetts Medical School, Worcester, MA 01605, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374467" target="_blank"〉PubMed〈/a〉

    Requirement of the DEAD-Box protein ded1p for messenger RNA translation (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-03-07
    Description: The DED1 gene, which encodes a putative RNA helicase, has been implicated in nuclear pre-messenger RNA splicing in the yeast Saccharomyces cerevisiae. It is shown here by genetic and biochemical analysis that translation, rather than splicing, is severely impaired in two newly isolated ded1 conditional mutants. Preliminary evidence suggests that the protein Ded1p may be required for the initiation step of translation, as is the distinct DEAD-box protein, eukaryotic initiation factor 4A (eIF4A). The DED1 gene could be functionally replaced by a mouse homolog, PL10, which suggests that the function of Ded1p in translation is evolutionarily conserved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chuang, R Y -- Weaver, P L -- Liu, Z -- Chang, T H -- GM48752/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Mar 7;275(5305):1468-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular, Cellular, and Developmental Biology Program, Ohio State University, Columbus, OH 43210, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9045610" target="_blank"〉PubMed〈/a〉

    Mating type switching in yeast controlled by asymmetric localization of ASH1 mRNA (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-18
    Description: Cell divisions that produce progeny differing in their patterns of gene expression are key to the development of multicellular organisms. In the budding yeast Saccharomyces cerevisiae, mother cells but not daughter cells can switch mating type because they selectively express the HO endonuclease gene. This asymmetry is due to the preferential accumulation of an unstable transcriptional repressor protein, Ash1p, in daughter cell nuclei. Here it is shown that ASH1 messenger RNA (mRNA) preferentially accumulates in daughter cells by a process that is dependent on actin and myosin. A cis-acting element in the 3'-untranslated region of ASH1 mRNA is sufficient to localize a chimeric RNA to daughter cells. These results suggest that localization of mRNA may have been an early property of the eukaryotic lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Long, R M -- Singer, R H -- Meng, X -- Gonzalez, I -- Nasmyth, K -- Jansen, R P -- 7 F32 HD08088-02/HD/NICHD NIH HHS/ -- GM54887/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jul 18;277(5324):383-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Structural Biology, Albert Einstein College of Medicine, 1300 Morris Park Avenue, Bronx, NY 10461, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9219698" target="_blank"〉PubMed〈/a〉

    Genetic testing for cancer risk (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-14
    Description: Genetic testing for cancer susceptibility is already part of the clinical management of families with some of the well-defined (but uncommon) inherited cancer syndromes. In cases where the risks associated with a predisposing mutation are less certain, or where there is no clearly effective intervention to offer those with a positive result, its use is more controversial. Careful evaluation of costs and benefits, and of the efficacy of interventions in those found to be at risk, is essential and is only just beginning. An immediate challenge is to ensure that both health professionals and the public understand clearly the issues involved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ponder, B -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1050-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, University of Cambridge, Addenbrooke's Hospital, Box 238, Level 3 Lab Block, Hills Road, Cambridge CB2 2QQ, UK. bajp@mole.bio.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353178" target="_blank"〉PubMed〈/a〉

    Integrating genetic approaches into the discovery of anticancer drugs (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-14
    Description: The discovery of anticancer drugs is now driven by the numerous molecular alterations identified in tumor cells over the past decade. To exploit these alterations, it is necessary to understand how they define a molecular context that allows increased sensitivity to particular compounds. Traditional genetic approaches together with the new wealth of genomic information for both human and model organisms open up strategies by which drugs can be profiled for their ability to selectively kill cells in a molecular context that matches those found in tumors. Similarly, it may be possible to identify and validate new targets for drugs that would selectively kill tumor cells with a particular molecular context. This article outlines some of the ways that yeast genetics can be used to streamline anticancer drug discovery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hartwell, L H -- Szankasi, P -- Roberts, C J -- Murray, A W -- Friend, S H -- N01-BC65017/BC/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1064-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Seattle Project, Molecular Pharmacology Department, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353181" target="_blank"〉PubMed〈/a〉

    Osmotic activation of the HOG MAPK pathway via Ste11p MAPKKK: scaffold role of Pbs2p MAPKK (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-13
    Description: Exposure of the yeast Saccharomyces cerevisiae to high extracellular osmolarity induces the Sln1p-Ypd1p-Ssk1p two-component osmosensor to activate a mitogen-activated protein (MAP) kinase cascade composed of the Ssk2p and Ssk22p MAP kinase kinase kinases (MAPKKKs), the Pbs2p MAPKK, and the Hog1p MAPK. A second osmosensor, Sho1p, also activated Pbs2p and Hog1p, but did so through the Ste11p MAPKKK. Although Ste11p also participates in the mating pheromone-responsive MAPK cascade, there was no detectable cross talk between these two pathways. The MAPKK Pbs2p bound to the Sho1p osmosensor, the MAPKKK Ste11p, and the MAPK Hog1p. Thus, Pbs2p may serve as a scaffold protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Posas, F -- Saito, H -- GM50909/GM/NIGMS NIH HHS/ -- GM53415/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1702-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Tumor Immunology, Dana-Farber Cancer Institute, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9180081" target="_blank"〉PubMed〈/a〉

    Pain affect encoded in human anterior cingulate but not somatosensory cortex (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-15
    Description: Recent evidence demonstrating multiple regions of human cerebral cortex activated by pain has prompted speculation about their individual contributions to this complex experience. To differentiate cortical areas involved in pain affect, hypnotic suggestions were used to alter selectively the unpleasantness of noxious stimuli, without changing the perceived intensity. Positron emission tomography revealed significant changes in pain-evoked activity within anterior cingulate cortex, consistent with the encoding of perceived unpleasantness, whereas primary somatosensory cortex activation was unaltered. These findings provide direct experimental evidence in humans linking frontal-lobe limbic activity with pain affect, as originally suggested by early clinical lesion studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rainville, P -- Duncan, G H -- Price, D D -- Carrier, B -- Bushnell, M C -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):968-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉D-epartement de Psychologie and Centre de Recherche en Sciences Neurologiques, Universite de Montreal, Montreal, Quebec, Canada H3C 3J7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252330" target="_blank"〉PubMed〈/a〉

    Rescue of a Drosophila NF1 mutant phenotype by protein kinase A (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-02
    Description: The neurofibromatosis type 1 (NF1) tumor suppressor protein is thought to restrict cell proliferation by functioning as a Ras-specific guanosine triphosphatase-activating protein. However, Drosophila homozygous for null mutations of an NF1 homolog showed no obvious signs of perturbed Ras1-mediated signaling. Loss of NF1 resulted in a reduction in size of larvae, pupae, and adults. This size defect was not modified by manipulating Ras1 signaling but was restored by expression of activated adenosine 3', 5'-monophosphate-dependent protein kinase (PKA). Thus, NF1 and PKA appear to interact in a pathway that controls the overall growth of Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉The, I -- Hannigan, G E -- Cowley, G S -- Reginald, S -- Zhong, Y -- Gusella, J F -- Hariharan, I K -- Bernards, A -- NS22229/NS/NINDS NIH HHS/ -- NS34779/NS/NINDS NIH HHS/ -- NS36084/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 May 2;276(5313):791-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts General Hospital Cancer Center and Harvard Medical School Building 149, 13th Street, Charlestown, MA 02129, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9115203" target="_blank"〉PubMed〈/a〉

    A mouse model with features of familial combined hyperlipidemia (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-17
    Description: Familial combined hyperlipidemia (FCHL) is a common inherited lipid disorder, affecting 1 to 2 percent of the population in Westernized societies. Individuals with FCHL have large quantities of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) and develop premature coronary heart disease. A mouse model displaying some of the features of FCHL was created by crossing mice carrying the human apolipoprotein C-III (APOC3) transgene with mice deficient in the LDL receptor. A synergistic interaction between the apolipoprotein C-III and the LDL receptor defects produced large quantities of VLDL and LDL and enhanced the development of atherosclerosis. This mouse model may provide clues to the origin of human FCHL.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masucci-Magoulas, L -- Goldberg, I J -- Bisgaier, C L -- Serajuddin, H -- Francone, O L -- Breslow, J L -- Tall, A R -- HL 21006/HL/NHLBI NIH HHS/ -- HL 54591/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1997 Jan 17;275(5298):391-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Columbia University, 630 West 168 Street, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8994037" target="_blank"〉PubMed〈/a〉

    Formation of actin stress fibers and focal adhesions enhanced by Rho-kinase (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-28
    Description: The small guanosine triphosphatase (GTPase) Rho is implicated in the formation of stress fibers and focal adhesions in fibroblasts stimulated by extracellular signals such as lysophosphatidic acid (LPA). Rho-kinase is activated by Rho and may mediate some biological effects of Rho. Microinjection of the catalytic domain of Rho-kinase into serum-starved Swiss 3T3 cells induced the formation of stress fibers and focal adhesions, whereas microinjection of the inactive catalytic domain, the Rho-binding domain, or the pleckstrin-homology domain inhibited the LPA-induced formation of stress fibers and focal adhesions. Thus, Rho-kinase appears to mediate signals from Rho and to induce the formation of stress fibers and focal adhesions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amano, M -- Chihara, K -- Kimura, K -- Fukata, Y -- Nakamura, N -- Matsuura, Y -- Kaibuchi, K -- New York, N.Y. -- Science. 1997 Feb 28;275(5304):1308-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Signal Transduction, Nara Institute of Science and Technology, Ikoma 630-01, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9036856" target="_blank"〉PubMed〈/a〉

    Hypermethylated SUPERMAN epigenetic alleles in arabidopsis (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-22
    Description: Mutations in the SUPERMAN gene affect flower development in Arabidopsis. Seven heritable but unstable sup epi-alleles (the clark kent alleles) are associated with nearly identical patterns of excess cytosine methylation within the SUP gene and a decreased level of SUP RNA. Revertants of these alleles are largely demethylated at the SUP locus and have restored levels of SUP RNA. A transgenic Arabidopsis line carrying an antisense methyltransferase gene, which shows an overall decrease in genomic cytosine methylation, also contains a hypermethylated sup allele. Thus, disruption of methylation systems may yield more complex outcomes than expected and can result in methylation defects at known genes. The clark kent alleles differ from the antisense line because they do not show a general decrease in genomic methylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobsen, S E -- Meyerowitz, E M -- New York, N.Y. -- Science. 1997 Aug 22;277(5329):1100-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology 156-29, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9262479" target="_blank"〉PubMed〈/a〉

    A mRNA signal for the type III secretion of Yop proteins by Yersinia enterocolitica (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-14
    Description: Pathogenic Yersinia species have a specialized secretion system (type III) to target cytotoxic Yop proteins during infection. The signals of YopE and YopN sufficient for the secretion of translational reporter fusions were mapped to the first 15 codons. No common amino acid or peptide sequence could be identified among the secretion signals. Systematic mutagenesis of the secretion signal yielded mutants defective in Yop translation; however, no point mutants could be identified that specifically abolished secretion. Frameshift mutations that completely altered the peptide sequences of these signals also failed to prevent secretion. Thus, the signal that leads to the type III secretion of Yop proteins appears to be encoded in their messenger RNA rather than the peptide sequence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, D M -- Schneewind, O -- AI 07323/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1140-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Molecular Biology Institute, University of California, Los Angeles, School of Medicine, 10833 Le Conte Avenue, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353199" target="_blank"〉PubMed〈/a〉

    Description: The use of molecular phylogenies to examine evolutionary questions has become commonplace with the automation of DNA sequencing and the availability of efficient computer programs to perform phylogenetic analyses. The application of computer simulation and likelihood ratio tests to evolutionary hypotheses represents a recent methodological development in this field. Likelihood ratio tests have enabled biologists to address many questions in evolutionary biology that have been difficult to resolve in the past, such as whether host-parasite systems are cospeciating and whether models of DNA substitution adequately explain observed sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huelsenbeck, J P -- Rannala, B -- GM40282/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Apr 11;276(5310):227-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Biology, University of California, Berkeley, CA 94720, USA. john@mws4.biol.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9092465" target="_blank"〉PubMed〈/a〉

    Requirement of guanosine triphosphate-bound ran for signal-mediated nuclear protein export (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-20
    Description: A leucine-rich nuclear export signal (NES) allows rapid export of proteins from cell nuclei. Microinjection studies revealed a role for the guanosine triphosphatase (GTPase) Ran in NES-mediated export. Nuclear injection of a Ran mutant (Thr24 --〉 Asn) blocked protein export but not import, whereas depletion of the Ran nucleotide exchange factor RCC1 blocked protein import but not export. However, injection of Ran GTPase-activating protein (RanGAP) into RCC1-depleted cell nuclei inhibited export. Coinjection with Ran mutants insensitive to RanGAP prevented this inhibition. Therefore, NES-mediated protein export appears to require a Ran-GTP complex but does not require Ran-dependent GTP hydrolysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richards, S A -- Carey, K L -- Macara, I G -- EST3207122/ES/NIEHS NIH HHS/ -- GM 50526/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 20;276(5320):1842-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Vermont, Burlington, VT 05405, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9188526" target="_blank"〉PubMed〈/a〉

    Structural insights into the evolution of an antibody combining site (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-13
    Description: The crystal structures of a germline antibody Fab fragment and its complex with hapten have been solved at 2.1 A resolution. These structures are compared with the corresponding crystal structures of the affinity-matured antibody, 48G7, which has a 30,000 times higher affinity for hapten as a result of nine replacement somatic mutations. Significant changes in the configuration of the combining site occur upon binding of hapten to the germline antibody, whereas hapten binds to the mature antibody by a lock-and-key fit mechanism. The reorganization of the combining site that was nucleated by hapten binding is further optimized by somatic mutations that occur up to 15 from bound hapten. These results suggest that the binding potential of the primary antibody repertoire may be significantly expanded by the ability of germline antibodies to adopt more than one combining-site configuration, with both antigen binding and somatic mutation stabilizing the configuration with optimal hapten complementarity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wedemayer, G J -- Patten, P A -- Wang, L H -- Schultz, P G -- Stevens, R C -- R01 AI39089/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1665-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9180069" target="_blank"〉PubMed〈/a〉

    Life and death of neurons in the aging brain (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-10-23
    Description: Neurodegenerative disorders are characterized by extensive neuron death that leads to functional decline, but the neurobiological correlates of functional decline in normal aging are less well defined. For decades, it has been a commonly held notion that widespread neuron death in the neocortex and hippocampus is an inevitable concomitant of brain aging, but recent quantitative studies suggest that neuron death is restricted in normal aging and unlikely to account for age-related impairment of neocortical and hippocampal functions. In this article, the qualitative and quantitative differences between aging and Alzheimer's disease with respect to neuron loss are discussed, and age-related changes in functional and biochemical attributes of hippocampal circuits that might mediate functional decline in the absence of neuron death are explored. When these data are viewed comprehensively, it appears that the primary neurobiological substrates for functional impairment in aging differ in important ways from those in neurodegenerative disorders such as Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrison, J H -- Hof, P R -- AG05138/AG/NIA NIH HHS/ -- AG06647/AG/NIA NIH HHS/ -- MHDA52145/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1997 Oct 17;278(5337):412-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurobiology of Aging Laboratories, the Fishberg Research Center for Neurobiology, and the Department of Geriatrics and Adult Development, Mount Sinai School of Medicine, New York, NY 10029, USA. morrison@cortex.neuro.mssm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9334292" target="_blank"〉PubMed〈/a〉

    Description: In evaluating current combination drug regimens for treatment of human immunodeficiency virus (HIV) disease, it is important to determine the existence of viral reservoirs. After depletion of CD8 cells from the peripheral blood mononuclear cells (PBMCs) of both patients and normal donors, activation of patient CD4 lymphocytes with immobilized antibodies to CD3 and CD28 enabled the isolation of virus from PBMCs of six patients despite the suppression of their plasma HIV RNA to fewer than 50 copies per milliliter for up to 2 years.

    Interaction and regulation of subcellular localization of CED-4 by CED-9 (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-21
    Description: The Caenorhabditis elegans survival gene ced-9 regulates ced-4 activity and inhibits cell death, but the mechanism by which this occurs is unknown. Through a genetic screen for CED-4-binding proteins, CED-9 was identified as an interacting partner of CED-4. CED-9, but not loss-of-function mutants, associated specifically with CED-4 in yeast or mammalian cells. The CED-9 protein localized primarily to intracellular membranes and the perinuclear region, whereas CED-4 was distributed in the cytosol. Expression of CED-9, but not a mutant lacking the carboxy-terminal hydrophobic domain, targeted CED-4 from the cytosol to intracellular membranes in mammalian cells. Thus, the actions of CED-4 and CED-9 are directly linked, which could provide the basis for the regulation of programmed cell death in C. elegans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, D -- Wallen, H D -- Nunez, G -- CA-64556/CA/NCI NIH HHS/ -- T32A107413-03/PHS HHS/ -- New York, N.Y. -- Science. 1997 Feb 21;275(5303):1126-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology and Comprehensive Cancer Center, The University of Michigan Medical School, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9027313" target="_blank"〉PubMed〈/a〉

    Regulatory phosphorylation of AMPA-type glutamate receptors by CaM-KII during long-term potentiation (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-27
    Description: Long-term potentiation (LTP), a cellular model of learning and memory, requires calcium-dependent protein kinases. Induction of LTP increased the phosphorus-32 labeling of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptors (AMPA-Rs), which mediate rapid excitatory synaptic transmission. This AMPA-R phosphorylation appeared to be catalyzed by Ca2+- and calmodulin-dependent protein kinase II (CaM-KII): (i) it correlated with the activation and autophosphorylation of CaM-KII, (ii) it was blocked by the CaM-KII inhibitor KN-62, and (iii) its phosphorus-32 peptide map was the same as that of GluR1 coexpressed with activated CaM-KII in HEK-293 cells. This covalent modulation of AMPA-Rs in LTP provides a postsynaptic molecular mechanism for synaptic plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barria, A -- Muller, D -- Derkach, V -- Griffith, L C -- Soderling, T R -- NS27037/NS/NINDS NIH HHS/ -- R01 GM054408/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 27;276(5321):2042-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland, OR 97201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9197267" target="_blank"〉PubMed〈/a〉

    Large porous particles for pulmonary drug delivery (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-20
    Description: A new type of inhalation aerosol, characterized by particles of small mass density and large size, permitted the highly efficient delivery of inhaled therapeutics into the systemic circulation. Particles with mass densities less than 0.4 gram per cubic centimeter and mean diameters exceeding 5 micrometers were inspired deep into the lungs and escaped the lungs' natural clearance mechanisms until the inhaled particles delivered their therapeutic payload. Inhalation of large porous insulin particles resulted in elevated systemic levels of insulin and suppressed systemic glucose levels for 96 hours, whereas small nonporous insulin particles had this effect for only 4 hours. High systemic bioavailability of testosterone was also achieved by inhalation delivery of porous particles with a mean diameter (20 micrometers) approximately 10 times that of conventional inhaled therapeutic particles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Edwards, D A -- Hanes, J -- Caponetti, G -- Hrkach, J -- Ben-Jebria, A -- Eskew, M L -- Mintzes, J -- Deaver, D -- Lotan, N -- Langer, R -- GM26698/GM/NIGMS NIH HHS/ -- HD29125/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 20;276(5320):1868-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Pennsylvania State University, 204 Fenske Laboratory, University Park, PA 16802, USA. dxe11@psuv.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9188534" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1997-04-18
    Description: The severity of the malaria pandemic in the tropics is aggravated by the ongoing spread of parasite resistance to antimalarial drugs and mosquito resistance to insecticides. A strain of Anopheles gambiae, normally a major vector for human malaria in Africa, can encapsulate and kill the malaria parasites within a melanin-rich capsule in the mosquito midgut. Genetic mapping revealed one major and two minor quantitative trait loci (QTLs) for this encapsulation reaction. Understanding such antiparasite mechanisms in mosquitoes may lead to new strategies for malaria control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zheng, L -- Cornel, A J -- Wang, R -- Erfle, H -- Voss, H -- Ansorge, W -- Kafatos, F C -- Collins, F H -- New York, N.Y. -- Science. 1997 Apr 18;276(5311):425-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Molecular Biology Laboratory, Meyerhofstrasse 1, 69117 Heidelberg, Germany.

    Identification of a reservoir for HIV-1 in patients on highly active antiretroviral therapy (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-21
    Description: The hypothesis that quiescent CD4+ T lymphocytes carrying proviral DNA provide a reservoir for human immunodeficiency virus-type 1 (HIV-1) in patients on highly active antiretroviral therapy (HAART) was examined. In a study of 22 patients successfully treated with HAART for up to 30 months, replication-competent virus was routinely recovered from resting CD4+ T lymphocytes. The frequency of resting CD4+ T cells harboring latent HIV-1 was low, 0.2 to 16.4 per 10(6) cells, and, in cross-sectional analysis, did not decrease with increasing time on therapy. The recovered viruses generally did not show mutations associated with resistance to the relevant antiretroviral drugs. This reservoir of nonevolving latent virus in resting CD4+ T cells should be considered in deciding whether to terminate treatment in patients who respond to HAART.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finzi, D -- Hermankova, M -- Pierson, T -- Carruth, L M -- Buck, C -- Chaisson, R E -- Quinn, T C -- Chadwick, K -- Margolick, J -- Brookmeyer, R -- Gallant, J -- Markowitz, M -- Ho, D D -- Richman, D D -- Siliciano, R F -- AI23871/AI/NIAID NIH HHS/ -- AI27670/AI/NIAID NIH HHS/ -- AI28108/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 Nov 14;278(5341):1295-300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, 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/9360927" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1997-10-06
    Description: Familial adenomatous polyposis coli (FAP) is a disease characterized by the development of multiple colorectal adenomas, and affected individuals carry germline mutations in the APC gene. With the use of a conditional gene targeting system, a mouse model of FAP was created that circumvents the embryonic lethality of Apc deficiency and directs Apc inactivation specifically to the colorectal epithelium. loxP sites were inserted into the introns around Apc exon 14, and the resultant mutant allele (Apc580S) was introduced into the mouse germline. Mice homozygous for Apc580S were normal; however, upon infection of the colorectal region with an adenovirus encoding the Cre recombinase, the mice developed adenomas within 4 weeks. The adenomas showed deletion of Apc exon 14, indicating that the loss of Apc function was caused by Cre-loxP-mediated recombination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibata, H -- Toyama, K -- Shioya, H -- Ito, M -- Hirota, M -- Hasegawa, S -- Matsumoto, H -- Takano, H -- Akiyama, T -- Toyoshima, K -- Kanamaru, R -- Kanegae, Y -- Saito, I -- Nakamura, Y -- Shiba, K -- Noda, T -- New York, N.Y. -- Science. 1997 Oct 3;278(5335):120-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Cancer Institute, Toshima-ku, Tokyo 170, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9311916" target="_blank"〉PubMed〈/a〉

    Description: Signaling cascades triggered by receptor tyrosine kinases (RTKs) participate in diverse developmental processes. The active state of these signaling pathways was monitored by examination of the in situ distribution of the active, dual phosphorylated form of mitogen-activated protein kinase (ERK) with a specific monoclonal antibody. Detection of the active state of the Drosophila epidermal growth factor receptor (DER) pathway allowed the visualization of gradients and boundaries of receptor activation, assessment of the distribution of activating ligands, and analysis of interplay with the inhibitory ligand Argos. This in situ approach can be used to monitor other receptor-triggered pathways in a wide range of organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabay, L -- Seger, R -- Shilo, B Z -- New York, N.Y. -- Science. 1997 Aug 22;277(5329):1103-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, Weizmann Institute of Science, Rehovot 76100, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9262480" target="_blank"〉PubMed〈/a〉

    Receptor and betagamma binding sites in the alpha subunit of the retinal G protein transducin (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-17
    Description: Transmembrane receptors for hormones, neurotransmitters, light, and odorants mediate their cellular effects by activating heterotrimeric guanine nucleotide-binding proteins (G proteins). Crystal structures have revealed contact surfaces between G protein subunits, but not the surfaces or molecular mechanism through which Galphabetagamma responds to activation by transmembrane receptors. Such a surface was identified from the results of testing 100 mutant alpha subunits of the retinal G protein transducin for their ability to interact with rhodopsin. Sites at which alanine substitutions impaired this interaction mapped to two distinct Galpha surfaces: a betagamma-binding surface and a putative receptor-interacting surface. On the basis of these results a mechanism for receptor-catalyzed exchange of guanosine diphosphate for guanosine triphosphate is proposed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Onrust, R -- Herzmark, P -- Chi, P -- Garcia, P D -- Lichtarge, O -- Kingsley, C -- Bourne, H R -- CA-54427/CA/NCI NIH HHS/ -- GM-27800/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jan 17;275(5298):381-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, CA 94143-0450, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8994033" target="_blank"〉PubMed〈/a〉

    Antagonism of central melanocortin receptors in vitro and in vivo by agouti-related protein (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-10-06
    Description: Expression of Agouti protein is normally limited to the skin where it affects pigmentation, but ubiquitous expression causes obesity. An expressed sequence tag was identified that encodes Agouti-related protein, whose RNA is normally expressed in the hypothalamus and whose levels were increased eightfold in ob/ob mice. Recombinant Agouti-related protein was a potent, selective antagonist of Mc3r and Mc4r, melanocortin receptor subtypes implicated in weight regulation.

    Circadian rhythms in rapidly dividing cyanobacteria (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-10
    Description: The long-standing supposition that the biological clock cannot function in cells that divide more rapidly than the circadian cycle was investigated. During exponential growth in which the generation time was 10 hours, the profile of bioluminescence from a reporter strain of the cyanobacterium Synechococcus (species PCC 7942) matched a model based on the assumption that cells proliferate exponentially and the bioluminescence of each cell oscillates in a cosine fashion. Some messenger RNAs showed a circadian rhythm in abundance during continuous exponential growth with a doubling time of 5 to 6 hours. Thus, the cyanobacterial circadian clock functions in cells that divide three or more times during one circadian cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kondo, T -- Mori, T -- Lebedeva, N V -- Aoki, S -- Ishiura, M -- Golden, S S -- New York, N.Y. -- Science. 1997 Jan 10;275(5297):224-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biological Science, Graduate School of Science, Nagoya University, Chikusa, Nagoya, 464-01 Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8985018" target="_blank"〉PubMed〈/a〉

    Crystal structure of protein farnesyltransferase at 2.25 angstrom resolution (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-03-21
    Description: Protein farnesyltransferase (FTase) catalyzes the carboxyl-terminal lipidation of Ras and several other cellular signal transduction proteins. The essential nature of this modification for proper function of these proteins has led to the emergence of FTase as a target for the development of new anticancer therapy. Inhibition of this enzyme suppresses the transformed phenotype in cultured cells and causes tumor regression in animal models. The crystal structure of heterodimeric mammalian FTase was determined at 2.25 angstrom resolution. The structure shows a combination of two unusual domains: a crescent-shaped seven-helical hairpin domain and an alpha-alpha barrel domain. The active site is formed by two clefts that intersect at a bound zinc ion. One cleft contains a nine-residue peptide that may mimic the binding of the Ras substrate; the other cleft is lined with highly conserved aromatic residues appropriate for binding the farnesyl isoprenoid with required specificity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Park, H W -- Boduluri, S R -- Moomaw, J F -- Casey, P J -- Beese, L S -- GM46372/GM/NIGMS NIH HHS/ -- GM52382/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Mar 21;275(5307):1800-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Duke University Medical Center, Durham, NC 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9065406" target="_blank"〉PubMed〈/a〉

    Positional cloning of the gene for multiple endocrine neoplasia-type 1 (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-04-18
    Description: Multiple endocrine neoplasia-type 1 (MEN1) is an autosomal dominant familial cancer syndrome characterized by tumors in parathyroids, enteropancreatic endocrine tissues, and the anterior pituitary. DNA sequencing from a previously identified minimal interval on chromosome 11q13 identified several candidate genes, one of which contained 12 different frameshift, nonsense, missense, and in-frame deletion mutations in 14 probands from 15 families. The MEN1 gene contains 10 exons and encodes a ubiquitously expressed 2.8-kilobase transcript. The predicted 610-amino acid protein product, termed menin, exhibits no apparent similarities to any previously known proteins. The identification of MEN1 will enable improved understanding of the mechanism of endocrine tumorigenesis and should facilitate early diagnosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chandrasekharappa, S C -- Guru, S C -- Manickam, P -- Olufemi, S E -- Collins, F S -- Emmert-Buck, M R -- Debelenko, L V -- Zhuang, Z -- Lubensky, I A -- Liotta, L A -- Crabtree, J S -- Wang, Y -- Roe, B A -- Weisemann, J -- Boguski, M S -- Agarwal, S K -- Kester, M B -- Kim, Y S -- Heppner, C -- Dong, Q -- Spiegel, A M -- Burns, A L -- Marx, S J -- New York, N.Y. -- Science. 1997 Apr 18;276(5311):404-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Gene Transfer, National Human Genome Research Institute (NHGRI), 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/9103196" target="_blank"〉PubMed〈/a〉

    Requirement of Drosophila NF1 for activation of adenylyl cyclase by PACAP38-like neuropeptides (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-02
    Description: The human neurofibromatosis type 1 (NF1) tumor suppressor protein functions as a Ras-specific guanosine triphosphatase-activating protein, but the identity of Ras- mediated pathways modulated by NF1 remains unknown. A study of Drosophila NF1 mutants revealed that NF1 is essential for the cellular response to the neuropeptide PACAP38 (pituitary adenylyl cyclase-activating polypeptide) at the neuromuscular junction. The peptide induced a 100-fold enhancement of potassium currents by activating the Ras-Raf and adenylyl cyclase-adenosine 3',5'-monophosphate (cAMP) pathways. This response was eliminated in NF1 mutants. NF1 appears to regulate the rutabaga-encoded adenylyl cyclase rather than the Ras-Raf pathway. Moreover, the NF1 defect was rescued by the exposure of cells to pharmacological treatment that increased concentrations of cAMP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guo, H F -- The, I -- Hannan, F -- Bernards, A -- Zhong, Y -- R01-NS31747/NS/NINDS NIH HHS/ -- R01-NS34779/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1997 May 2;276(5313):795-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, 1 Bungtown Road, Cold Spring Harbor, NY 11724, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9115204" target="_blank"〉PubMed〈/a〉

    Pericyte loss and microaneurysm formation in PDGF-B-deficient mice (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-11
    Description: Platelet-derived growth factor (PDGF)-B-deficient mouse embryos were found to lack microvascular pericytes, which normally form part of the capillary wall, and they developed numerous capillary microaneurysms that ruptured at late gestation. Endothelial cells of the sprouting capillaries in the mutant mice appeared to be unable to attract PDGF-Rbeta-positive pericyte progenitor cells. Pericytes may contribute to the mechanical stability of the capillary wall. Comparisons made between PDGF null mouse phenotypes suggest a general role for PDGFs in the development of myofibroblasts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindahl, P -- Johansson, B R -- Leveen, P -- Betsholtz, C -- New York, N.Y. -- Science. 1997 Jul 11;277(5323):242-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Biochemistry, University of Goteborg, Medicinaregatan 9A, S-413 90 Goteborg, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9211853" target="_blank"〉PubMed〈/a〉

    The Ras-RasGAP complex: structural basis for GTPase activation and its loss in oncogenic Ras mutants (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-18
    Description: The three-dimensional structure of the complex between human H-Ras bound to guanosine diphosphate and the guanosine triphosphatase (GTPase)-activating domain of the human GTPase-activating protein p120GAP (GAP-334) in the presence of aluminum fluoride was solved at a resolution of 2.5 angstroms. The structure shows the partly hydrophilic and partly hydrophobic nature of the communication between the two molecules, which explains the sensitivity of the interaction toward both salts and lipids. An arginine side chain (arginine-789) of GAP-334 is supplied into the active site of Ras to neutralize developing charges in the transition state. The switch II region of Ras is stabilized by GAP-334, thus allowing glutamine-61 of Ras, mutation of which activates the oncogenic potential, to participate in catalysis. The structural arrangement in the active site is consistent with a mostly associative mechanism of phosphoryl transfer and provides an explanation for the activation of Ras by glycine-12 and glutamine-61 mutations. Glycine-12 in the transition state mimic is within van der Waals distance of both arginine-789 of GAP-334 and glutamine-61 of Ras, and even its mutation to alanine would disturb the arrangements of residues in the transition state.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheffzek, K -- Ahmadian, M R -- Kabsch, W -- Wiesmuller, L -- Lautwein, A -- Schmitz, F -- Wittinghofer, A -- New York, N.Y. -- Science. 1997 Jul 18;277(5324):333-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur molekulare Physiologie, Abteilung Strukturelle Biologie, Rheinlanddamm 201, 44139 Dortmund, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9219684" target="_blank"〉PubMed〈/a〉

    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〉

    Publication Date: 1997-01-24
    Description: Lymphocyte-specific interferon regulatory factor (LSIRF) (now called IRF4) is a transcription factor expressed only in lymphocytes. Mice deficient in IRF4 showed normal distribution of B and T lymphocyes at 4 to 5 weeks of age but developed progressive generalized lymphadenopathy. IRF4-deficient mice exhibited a profound reduction in serum immunoglobulin concentrations and did not mount detectable antibody responses. T lymphocyte function was also impaired in vivo; these mice could not generate cytotoxic or antitumor responses. Thus, IRF4 is essential for the function and homeostasis of both mature B and mature T lymphocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mittrucker, H W -- Matsuyama, T -- Grossman, A -- Kundig, T M -- Potter, J -- Shahinian, A -- Wakeham, A -- Patterson, B -- Ohashi, P S -- Mak, T W -- New York, N.Y. -- Science. 1997 Jan 24;275(5299):540-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, University of Toronto, Toronto, Ontario, M5G 2C1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8999800" target="_blank"〉PubMed〈/a〉

    Description: Transport of membrane proteins between intracellular compartments requires specific sequences in the protein cytoplasmic domain to direct packaging into vesicle shuttles. A sequence that mediates export from the endoplasmic reticulum (ER) has proved elusive. A di-acidic signal (Asp-X-Glu, where X represents any amino acid) on the cytoplasmic tail of vesicular stomatitis virus glycoprotein (VSV-G) and other cargo molecules was required for efficient recruitment to vesicles mediating export from the ER in baby hamster kidney cells. The existence of such a signal provides evidence that export from the ER occurs through a selective mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nishimura, N -- Balch, W E -- GM 42336/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jul 25;277(5325):556-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular 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/9228004" target="_blank"〉PubMed〈/a〉

    Fyn-kinase as a determinant of ethanol sensitivity: relation to NMDA-receptor function (1997)

    Details
    Publication Date: 1997-10-24
    Description: Animals vary in their sensitivity to ethanol, a trait at least partly determined by genetic factors. In order to identify possible responsible genes, mice lacking Fyn, a non-receptor type tyrosine kinase, were investigated. These mice were hypersensitive to the hypnotic effect of ethanol. The administration of ethanol enhanced tyrosine phosphorylation of the N-methyl-D-aspartate receptor (NMDAR) in the hippocampus of control mice but not in Fyn-deficient mice.

    Alternative cleavage of Alzheimer-associated presenilins during apoptosis by a caspase-3 family protease (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-18
    Description: Most cases of early-onset familial Alzheimer's disease (FAD) are caused by mutations in the genes encoding the presenilin 1 (PS1) and PS2 proteins, both of which undergo regulated endoproteolytic processing. During apoptosis, PS1 and PS2 were shown to be cleaved at sites distal to their normal cleavage sites by a caspase-3 family protease. In cells expressing PS2 containing the asparagine-141 FAD mutant, the ratio of alternative to normal PS2 cleavage fragments was increased relative to wild-type PS2-expressing cells, suggesting a potential role for apoptosis-associated cleavage of presenilins in the pathogenesis of Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, T W -- Pettingell, W H -- Jung, Y K -- Kovacs, D M -- Tanzi, R E -- New York, N.Y. -- Science. 1997 Jul 18;277(5324):373-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genetics and Aging Unit, Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9219695" target="_blank"〉PubMed〈/a〉

    Genetic feminization of pheromones and its behavioral consequences in Drosophila males (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-06
    Description: Pheromones are intraspecific chemical signals important for mate attraction and discrimination. In the fruit fly Drosophila melanogaster, hydrocarbons on the cuticular surface of the animal are sexually dimorphic in both their occurrence and their effects: Female-specific molecules stimulate male sexual excitation, whereas the predominant male-specific molecule tends to inhibit male excitation. Complete feminization of the pheromone mixture produced by males was induced by targeted expression of the transformer gene in adult oenocytes (subcuticular abdominal cells) or by ubiquitous expression during early imaginal life. The resulting flies generally exhibited male heterosexual orientation but elicited homosexual courtship from other males.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferveur, J F -- Savarit, F -- O'Kane, C J -- Sureau, G -- Greenspan, R J -- Jallon, J M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1997 Jun 6;276(5318):1555-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mecanismes de communication, Unite de Recherche Associee-CNRS 1491, Batiment 446, Universite Paris-Sud, 91405, Orsay-Cedex, France. ferveur@ext.jussieu.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9171057" target="_blank"〉PubMed〈/a〉

    daf-2, an insulin receptor-like gene that regulates longevity and diapause in Caenorhabditis elegans (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-15
    Description: A C. elegans neurosecretory signaling system regulates whether animals enter the reproductive life cycle or arrest development at the long-lived dauer diapause stage. daf-2, a key gene in the genetic pathway that mediates this endocrine signaling, encodes an insulin receptor family member. Decreases in DAF-2 signaling induce metabolic and developmental changes, as in mammalian metabolic control by the insulin receptor. Decreased DAF-2 signaling also causes an increase in life-span. Life-span regulation by insulin-like metabolic control is analogous to mammalian longevity enhancement induced by caloric restriction, suggesting a general link between metabolism, diapause, and longevity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kimura, K D -- Tissenbaum, H A -- Liu, Y -- Ruvkun, G -- R01AG14161/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):942-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252323" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1997-10-23
    Description: The role of genetics in determining life-span is complex and paradoxical. Although the heritability of life-span is relatively minor, some genetic variants significantly modify senescence of mammals and invertebrates, with both positive and negative impacts on age-related disorders and life-spans. In certain examples, the gene variants alter metabolic pathways, which could thereby mediate interactions with nutritional and other environmental factors that influence life-span. Given the relatively minor effect and variable penetrance of genetic risk factors that appear to affect survival and health at advanced ages, life-style and other environmental influences may profoundly modify outcomes of aging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finch, C E -- Tanzi, R E -- New York, N.Y. -- Science. 1997 Oct 17;278(5337):407-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurogerontology Division, Andrus Gerontology Center, and Department of Biological Sciences, University of Southern California, 3715 McClintock Avenue, Los Angeles, CA 90089-0191, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9334291" target="_blank"〉PubMed〈/a〉

    Publication Date: 1997-12-31
    Description: Lhx3 and Lhx4 (Gsh4), two closely related LIM homeobox genes, determine formation of the pituitary gland in mice. Rathke's pouch is formed in two steps-first as a rudiment and later as a definitive pouch. Lhx3 and Lhx4 have redundant control over formation of the definitive pouch. Lhx3 controls a subsequent step of pituitary fate commitment. Thereafter, Lhx3 and Lhx4 together regulate proliferation and differentiation of pituitary-specific cell lineages. Thus, Lhx3 and Lhx4 dictate pituitary organ identity by controlling developmental decisions at multiple stages of organogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheng, H Z -- Moriyama, K -- Yamashita, T -- Li, H -- Potter, S S -- Mahon, K A -- Westphal, H -- New York, N.Y. -- Science. 1997 Dec 5;278(5344):1809-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Mammalian Genes and Development, National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9388186" target="_blank"〉PubMed〈/a〉

    Neighborhoods and violent crime: a multilevel study of collective efficacy (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-15
    Description: It is hypothesized that collective efficacy, defined as social cohesion among neighbors combined with their willingness to intervene on behalf of the common good, is linked to reduced violence. This hypothesis was tested on a 1995 survey of 8782 residents of 343 neighborhoods in Chicago, Illinois. Multilevel analyses showed that a measure of collective efficacy yields a high between-neighborhood reliability and is negatively associated with variations in violence, when individual-level characteristics, measurement error, and prior violence are controlled. Associations of concentrated disadvantage and residential instability with violence are largely mediated by collective efficacy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sampson, R J -- Raudenbush, S W -- Earls, F -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):918-24.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Sociology, University of Chicago, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252316" target="_blank"〉PubMed〈/a〉

    Neural correlates of motor memory consolidation (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-08
    Description: Computational studies suggest that acquisition of a motor skill involves learning an internal model of the dynamics of the task, which enables the brain to predict and compensate for mechanical behavior. During the hours that follow completion of practice, representation of the internal model gradually changes, becoming less fragile with respect to behavioral interference. Here, functional imaging of the brain demonstrates that within 6 hours after completion of practice, while performance remains unchanged, the brain engages new regions to perform the task; there is a shift from prefrontal regions of the cortex to the premotor, posterior parietal, and cerebellar cortex structures. This shift is specific to recall of an established motor skill and suggests that with the passage of time, there is a change in the neural representation of the internal model and that this change may underlie its increased functional stability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shadmehr, R -- Holcomb, H H -- New York, N.Y. -- Science. 1997 Aug 8;277(5327):821-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biomedical Engineering, School of Medicine, Johns Hopkins University, 720 Rutland Avenue, 419 Traylor, Baltimore, MD 21205-2195, USA. reza@bme.jhu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9242612" target="_blank"〉PubMed〈/a〉

    Description: The participation of medial temporal-lobe structures in memory performance was examined by functional magnetic resonance imaging of local blood oxygenation level-dependent signals. Signals were measured during encoding into memory complex scenes or line drawings and during retrieval from memory of previously studied line drawings or words. Encoding tasks yielded increased signals for unfamiliar information in a posterior medial-temporal region that were focused in the parahippocampal cortex. Retrieval tasks yielded increased signals for successfully remembered information in an anterior medial-temporal region that were focused in the subiculum. These results indicate that separate components of the human medial temporal-lobe memory system are active during distinct memory processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabrieli, J D -- Brewer, J B -- Desmond, J E -- Glover, G H -- New York, N.Y. -- Science. 1997 Apr 11;276(5310):264-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology and Neuroscience Program, Stanford University, Stanford, CA 94305, USA. gabrieli@psych.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9092477" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-09-05
    Description: Arrest of the cell cycle at the G2 checkpoint, induced by DNA damage, requires inhibitory phosphorylation of the kinase Cdc2 in both fission yeast and human cells. The kinase Wee1 and the phosphatase Cdc25, which regulate Cdc2 phosphorylation, were evaluated as targets of Chk1, a kinase essential for the checkpoint. Fission yeast cdc2-3w Deltacdc25 cells, which express activated Cdc2 and lack Cdc25, were responsive to Wee1 but insensitive to Chk1 and irradiation. Expression of large amounts of Chk1 produced the same phenotype as did loss of the cdc25 gene in cdc2-3w cells. Cdc25 associated with Chk1 in vivo and was phosphorylated when copurified in Chk1 complexes. These findings identify Cdc25, but not Wee1, as a target of the DNA damage checkpoint.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Furnari, B -- Rhind, N -- Russell, P -- New York, N.Y. -- Science. 1997 Sep 5;277(5331):1495-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, The Scripps Research Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9278510" target="_blank"〉PubMed〈/a〉

    The product of the proto-oncogene c-cbl: a negative regulator of the Syk tyrosine kinase (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-04-18
    Description: Engagement of antigen and immunoglobulin receptors on hematopoietic cells is directly coupled to activation of nonreceptor protein tyrosine kinases (PTKs) that then phosphorylate critical intracellular substrates. In mast cells stimulated through the FcvarepsilonRI receptor, activation of several PTKs including Syk leads to degranulation and release of such mediators of the allergic response as histamine and serotonin. Regulation of Syk function occurred through interaction with the Cbl protein, itself a PTK substrate in this system. Overexpression of Cbl led to inhibition of Syk and suppression of serotonin release from mast cells, demonstrating its ability to inhibit a nonreceptor tyrosine kinase. Complex adaptor proteins such as Cbl can directly regulate the functions of the proteins they bind.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ota, Y -- Samelson, L E -- New York, N.Y. -- Science. 1997 Apr 18;276(5311):418-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell Biology and Metabolism Branch, National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892-5430, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9103201" target="_blank"〉PubMed〈/a〉

    Independent and additive effects of central POMC and leptin pathways on murine obesity (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-12-31
    Description: The lethal yellow (AY/a) mouse has a defect in proopiomelanocortin (POMC) signaling in the brain that leads to obesity, and is resistant to the anorexigenic effects of the hormone leptin. It has been proposed that the weight-reducing effects of leptin are thus transmitted primarily by way of POMC neurons. However, the central effects of defective POMC signaling, and the absence of leptin, on weight gain in double-mutant lethal yellow (AY/a) leptin-deficient (lepob/lepob) mice were shown to be independent and additive. Furthermore, deletion of the leptin gene restored leptin sensitivity to AY/a mice. This result implies that in the AY/a mouse, obesity is independent of leptin action, and resistance to leptin results from desensitization of leptin signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boston, B A -- Blaydon, K M -- Varnerin, J -- Cone, R D -- DK/AR517330/DK/NIDDK NIH HHS/ -- DK02404/DK/NIDDK NIH HHS/ -- HD33703/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1641-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, Oregon Health Sciences University, Portland, OR 97201, USA.

    Environment and cancer: who are susceptible? (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-14
    Description: Acting in concert with individual susceptibility, environmental factors such as smoking, diet, and pollutants play a role in most human cancer. However, new molecular evidence indicates that specific groups-characterized by predisposing genetic traits or ethnicity, the very young, and women-may have heightened risk from certain exposures. This is illustrated by molecular epidemiologic studies of environmental carcinogens such as polycyclic aromatic hydrocarbons and aromatic amines. Individual genetic screening for rare high-risk traits or for more common, low-penetrant susceptibility genes is problematic and not routinely recommended. However, knowledge of the full spectrum of both genetic and acquired susceptibility in the population will be instrumental in developing health and regulatory policies that increase protection of the more susceptible groups from risks of environmental carcinogens. This will necessitate revision of current risk assessment methodologies to explicitly account for individual variation in susceptibility to environmental carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perera, F P -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1068-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Environmental Health Sciences, Columbia University School of Public Health, 60 Haven Avenue, B-1, New York, NY 10032, USA. fpp1@columbia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353182" target="_blank"〉PubMed〈/a〉

    Trim28 is required for epigenetic stability during mouse oocyte to embryo transition (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-24
    Description: Phenotypic variability in genetic disease is usually attributed to genetic background variation or environmental influence. Here, we show that deletion of a single gene, Trim28 (Kap1 or Tif1beta), from the maternal germ line alone, on an otherwise identical genetic background, results in severe phenotypic and epigenetic variability that leads to embryonic lethality. We identify early and minute epigenetic variations in blastomeres of the preimplantation embryo of these animals, suggesting that the embryonic lethality may result from the misregulation of genomic imprinting in mice lacking maternal Trim28. Our results reveal the long-range effects of a maternal gene deletion on epigenetic memory and illustrate the delicate equilibrium of maternal and zygotic factors during nuclear reprogramming.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Messerschmidt, Daniel M -- de Vries, Wilhelmine -- Ito, Mitsuteru -- Solter, Davor -- Ferguson-Smith, Anne -- Knowles, Barbara B -- 079249/Wellcome Trust/United Kingdom -- 095606/Wellcome Trust/United Kingdom -- MR/J001597/1/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1499-502. doi: 10.1126/science.1216154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mammalian Development Group, Institute of Medical Biology, Singapore.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442485" target="_blank"〉PubMed〈/a〉

    Ancestral developmental potential facilitates parallel evolution in ants (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-10
    Description: Complex worker caste systems have contributed to the evolutionary success of advanced ant societies; however, little is known about the developmental processes underlying their origin and evolution. We combined hormonal manipulation, gene expression, and phylogenetic analyses with field observations to understand how novel worker subcastes evolve. We uncovered an ancestral developmental potential to produce a "supersoldier" subcaste that has been actualized at least two times independently in the hyperdiverse ant genus Pheidole. This potential has been retained and can be environmentally induced throughout the genus. Therefore, the retention and induction of this potential have facilitated the parallel evolution of supersoldiers through a process known as genetic accommodation. The recurrent induction of ancestral developmental potential may facilitate the adaptive and parallel evolution of phenotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rajakumar, Rajendhran -- San Mauro, Diego -- Dijkstra, Michiel B -- Huang, Ming H -- Wheeler, Diana E -- Hiou-Tim, Francois -- Khila, Abderrahman -- Cournoyea, Michael -- Abouheif, Ehab -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):79-82. doi: 10.1126/science.1211451.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, McGill University, 1205 Avenue Dr. Penfield, Montreal, Quebec, Canada, H3A 1B1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22223805" target="_blank"〉PubMed〈/a〉

    MARF1 regulates essential oogenic processes in mice (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-24
    Description: Development of fertilization-competent oocytes depends on integrated processes controlling meiosis, cytoplasmic development, and maintenance of genomic integrity. We show that meiosis arrest female 1 (MARF1) is required for these processes in mammalian oocytes. Mutations of Marf1 cause female infertility characterized by up-regulation of a cohort of transcripts, increased retrotransposon expression, defective cytoplasmic maturation, and meiotic arrest. Up-regulation of protein phosphatase 2 catalytic subunit (PPP2CB) is key to the meiotic arrest phenotype. Moreover, Iap and Line1 retrotransposon messenger RNAs are also up-regulated, and, concomitantly, DNA double-strand breaks are elevated in mutant oocytes. Therefore MARF1, by suppressing levels of specific transcripts, is an essential regulator of important oogenic processes leading to female fertility and the development of healthy offspring.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612990/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612990/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, You-Qiang -- Sugiura, Koji -- Sun, Fengyun -- Pendola, Janice K -- Cox, Gregory A -- Handel, Mary Ann -- Schimenti, John C -- Eppig, John J -- CA34196/CA/NCI NIH HHS/ -- HD42137/HD/NICHD NIH HHS/ -- P01 HD042137/HD/NICHD NIH HHS/ -- P30 CA034196/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1496-9. doi: 10.1126/science.1214680.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Jackson Laboratory, Bar Harbor, ME 04609, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442484" target="_blank"〉PubMed〈/a〉

    The ancient drug salicylate directly activates AMP-activated protein kinase (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-04-21
    Description: Salicylate, a plant product, has been in medicinal use since ancient times. More recently, it has been replaced by synthetic derivatives such as aspirin and salsalate, both of which are rapidly broken down to salicylate in vivo. At concentrations reached in plasma after administration of salsalate or of aspirin at high doses, salicylate activates adenosine monophosphate-activated protein kinase (AMPK), a central regulator of cell growth and metabolism. Salicylate binds at the same site as the synthetic activator A-769662 to cause allosteric activation and inhibition of dephosphorylation of the activating phosphorylation site, threonine-172. In AMPK knockout mice, effects of salicylate to increase fat utilization and to lower plasma fatty acids in vivo were lost. Our results suggest that AMPK activation could explain some beneficial effects of salsalate and aspirin in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3399766/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3399766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hawley, Simon A -- Fullerton, Morgan D -- Ross, Fiona A -- Schertzer, Jonathan D -- Chevtzoff, Cyrille -- Walker, Katherine J -- Peggie, Mark W -- Zibrova, Darya -- Green, Kevin A -- Mustard, Kirsty J -- Kemp, Bruce E -- Sakamoto, Kei -- Steinberg, Gregory R -- Hardie, D Grahame -- 080982/Wellcome Trust/United Kingdom -- 097726/Wellcome Trust/United Kingdom -- MC_U127088492/Medical Research Council/United Kingdom -- Canadian Institutes of Health Research/Canada -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 May 18;336(6083):918-22. doi: 10.1126/science.1215327.

    Airborne transmission of influenza A/H5N1 virus between ferrets (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-23
    Description: Highly pathogenic avian influenza A/H5N1 virus can cause morbidity and mortality in humans but thus far has not acquired the ability to be transmitted by aerosol or respiratory droplet ("airborne transmission") between humans. To address the concern that the virus could acquire this ability under natural conditions, we genetically modified A/H5N1 virus by site-directed mutagenesis and subsequent serial passage in ferrets. The genetically modified A/H5N1 virus acquired mutations during passage in ferrets, ultimately becoming airborne transmissible in ferrets. None of the recipient ferrets died after airborne infection with the mutant A/H5N1 viruses. Four amino acid substitutions in the host receptor-binding protein hemagglutinin, and one in the polymerase complex protein basic polymerase 2, were consistently present in airborne-transmitted viruses. The transmissible viruses were sensitive to the antiviral drug oseltamivir and reacted well with antisera raised against H5 influenza vaccine strains. Thus, avian A/H5N1 influenza viruses can acquire the capacity for airborne transmission between mammals without recombination in an intermediate host and therefore constitute a risk for human pandemic influenza.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herfst, Sander -- Schrauwen, Eefje J A -- Linster, Martin -- Chutinimitkul, Salin -- de Wit, Emmie -- Munster, Vincent J -- Sorrell, Erin M -- Bestebroer, Theo M -- Burke, David F -- Smith, Derek J -- Rimmelzwaan, Guus F -- Osterhaus, Albert D M E -- Fouchier, Ron A M -- DP1-OD000490-01/OD/NIH HHS/ -- HHSN266200700010C/PHS HHS/ -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1534-41. doi: 10.1126/science.1213362.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Virology, Erasmus Medical Center, Rotterdam, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22723413" target="_blank"〉PubMed〈/a〉

    Rapamycin-induced insulin resistance is mediated by mTORC2 loss and uncoupled from longevity (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-31
    Description: Rapamycin, an inhibitor of mechanistic target of rapamycin complex 1 (mTORC1), extends the life spans of yeast, flies, and mice. Calorie restriction, which increases life span and insulin sensitivity, is proposed to function by inhibition of mTORC1, yet paradoxically, chronic administration of rapamycin substantially impairs glucose tolerance and insulin action. We demonstrate that rapamycin disrupted a second mTOR complex, mTORC2, in vivo and that mTORC2 was required for the insulin-mediated suppression of hepatic gluconeogenesis. Further, decreased mTORC1 signaling was sufficient to extend life span independently from changes in glucose homeostasis, as female mice heterozygous for both mTOR and mLST8 exhibited decreased mTORC1 activity and extended life span but had normal glucose tolerance and insulin sensitivity. Thus, mTORC2 disruption is an important mediator of the effects of rapamycin in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3324089/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3324089/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamming, Dudley W -- Ye, Lan -- Katajisto, Pekka -- Goncalves, Marcus D -- Saitoh, Maki -- Stevens, Deanna M -- Davis, James G -- Salmon, Adam B -- Richardson, Arlan -- Ahima, Rexford S -- Guertin, David A -- Sabatini, David M -- Baur, Joseph A -- 1F32AG032833-01A1/AG/NIA NIH HHS/ -- CA129105/CA/NCI NIH HHS/ -- F32 AG032833/AG/NIA NIH HHS/ -- P30DK19525/DK/NIDDK NIH HHS/ -- R01 CA129105/CA/NCI NIH HHS/ -- R01 CA129105-05/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Mar 30;335(6076):1638-43. doi: 10.1126/science.1215135.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22461615" target="_blank"〉PubMed〈/a〉

    Secreted kinase phosphorylates extracellular proteins that regulate biomineralization (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-15
    Description: Protein phosphorylation is a fundamental mechanism regulating nearly every aspect of cellular life. Several secreted proteins are phosphorylated, but the kinases responsible are unknown. We identified a family of atypical protein kinases that localize within the Golgi apparatus and are secreted. Fam20C appears to be the Golgi casein kinase that phosphorylates secretory pathway proteins within S-x-E motifs. Fam20C phosphorylates the caseins and several secreted proteins implicated in biomineralization, including the small integrin-binding ligand, N-linked glycoproteins (SIBLINGs). Consequently, mutations in Fam20C cause an osteosclerotic bone dysplasia in humans known as Raine syndrome. Fam20C is thus a protein kinase dedicated to the phosphorylation of extracellular proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3754843/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3754843/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tagliabracci, Vincent S -- Engel, James L -- Wen, Jianzhong -- Wiley, Sandra E -- Worby, Carolyn A -- Kinch, Lisa N -- Xiao, Junyu -- Grishin, Nick V -- Dixon, Jack E -- DK018024-37/DK/NIDDK NIH HHS/ -- DK018849-36/DK/NIDDK NIH HHS/ -- GM094575/GM/NIGMS NIH HHS/ -- R01 DK018849/DK/NIDDK NIH HHS/ -- R37 DK018024/DK/NIDDK NIH HHS/ -- T32 CA009523/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jun 1;336(6085):1150-3. doi: 10.1126/science.1217817.

    Gene loops enhance transcriptional directionality (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-29
    Description: Eukaryotic genomes are extensively transcribed, forming both messenger RNAs (mRNAs) and noncoding RNAs (ncRNAs). ncRNAs made by RNA polymerase II often initiate from bidirectional promoters (nucleosome-depleted chromatin) that synthesize mRNA and ncRNA in opposite directions. We demonstrate that, by adopting a gene-loop conformation, actively transcribed mRNA encoding genes restrict divergent transcription of ncRNAs. Because gene-loop formation depends on a protein factor (Ssu72) that coassociates with both the promoter and the terminator, the inactivation of Ssu72 leads to increased synthesis of promoter-associated divergent ncRNAs, referred to as Ssu72-restricted transcripts (SRTs). Similarly, inactivation of individual gene loops by gene mutation enhances SRT synthesis. We demonstrate that gene-loop conformation enforces transcriptional directionality on otherwise bidirectional promoters.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3563069/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3563069/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tan-Wong, Sue Mei -- Zaugg, Judith B -- Camblong, Jurgi -- Xu, Zhenyu -- Zhang, David W -- Mischo, Hannah E -- Ansari, Aseem Z -- Luscombe, Nicholas M -- Steinmetz, Lars M -- Proudfoot, Nick J -- 091805/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Nov 2;338(6107):671-5. doi: 10.1126/science.1224350.

    Erasure of a spinal memory trace of pain by a brief, high-dose opioid administration (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-17
    Description: Painful stimuli activate nociceptive C fibers and induce synaptic long-term potentiation (LTP) at their spinal terminals. LTP at C-fiber synapses represents a cellular model for pain amplification (hyperalgesia) and for a memory trace of pain. mu-Opioid receptor agonists exert a powerful but reversible depression at C-fiber synapses that renders the continuous application of low opioid doses the gold standard in pain therapy. We discovered that brief application of a high opioid dose reversed various forms of activity-dependent LTP at C-fiber synapses. Depotentiation involved Ca(2+)-dependent signaling and normalization of the phosphorylation state of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors. This also reversed hyperalgesia in behaving animals. Opioids thus not only temporarily dampen pain but may also erase a spinal memory trace of pain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drdla-Schutting, Ruth -- Benrath, Justus -- Wunderbaldinger, Gabriele -- Sandkuhler, Jurgen -- New York, N.Y. -- Science. 2012 Jan 13;335(6065):235-8. doi: 10.1126/science.1211726.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurophysiology, Center for Brain Research, Medical University of Vienna, A-1090 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22246779" target="_blank"〉PubMed〈/a〉

    Bateman in nature: predation on offspring reduces the potential for sexual selection (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-10
    Description: Sexual selection is driven by competition for mates, and the advantage of a competitor is determined by the number of offspring it produces. Early experiments by Angus Bateman characterized this interaction, and the quantitative relationship between a male's number of mates and number of offspring is known as the Bateman slope. Sexual dimorphism, one of the most obvious results of sexual selection, largely requires a positive Bateman relationship, and the slope provides an estimate of the potential for sexual selection. However, natural selection from the environment can also influence male success, as can random effects, and some have argued for inclusion of the latter in calculations of mate success. Data from pronghorn (Antilocapra americana) reveal the presence of a positive Bateman slope in each year of a 10-year study. We found no evidence that random effects skewed male mating success; however, substantial yearly variation in the Bateman slope due to predation on fawns was evident. These results support the validity of the Bateman relationship, yet they also demonstrate that environmental or extrinsic influences can limit the potential for sexual selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Byers, John -- Dunn, Stacey -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):802-4. doi: 10.1126/science.1224660.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Idaho, Moscow, ID 83844-3051, USA. jbyers@uidaho.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23139332" target="_blank"〉PubMed〈/a〉

    Evolution and functional impact of rare coding variation from deep sequencing of human exomes (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-19
    Description: As a first step toward understanding how rare variants contribute to risk for complex diseases, we sequenced 15,585 human protein-coding genes to an average median depth of 111x in 2440 individuals of European (n = 1351) and African (n = 1088) ancestry. We identified over 500,000 single-nucleotide variants (SNVs), the majority of which were rare (86% with a minor allele frequency less than 0.5%), previously unknown (82%), and population-specific (82%). On average, 2.3% of the 13,595 SNVs each person carried were predicted to affect protein function of ~313 genes per genome, and ~95.7% of SNVs predicted to be functionally important were rare. This excess of rare functional variants is due to the combined effects of explosive, recent accelerated population growth and weak purifying selection. Furthermore, we show that large sample sizes will be required to associate rare variants with complex traits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3708544/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3708544/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tennessen, Jacob A -- Bigham, Abigail W -- O'Connor, Timothy D -- Fu, Wenqing -- Kenny, Eimear E -- Gravel, Simon -- McGee, Sean -- Do, Ron -- Liu, Xiaoming -- Jun, Goo -- Kang, Hyun Min -- Jordan, Daniel -- Leal, Suzanne M -- Gabriel, Stacey -- Rieder, Mark J -- Abecasis, Goncalo -- Altshuler, David -- Nickerson, Deborah A -- Boerwinkle, Eric -- Sunyaev, Shamil -- Bustamante, Carlos D -- Bamshad, Michael J -- Akey, Joshua M -- Broad GO -- Seattle GO -- NHLBI Exome Sequencing Project -- R01 HG003229/HG/NHGRI NIH HHS/ -- RC2 HL-102923/HL/NHLBI NIH HHS/ -- RC2 HL-102924/HL/NHLBI NIH HHS/ -- RC2 HL-102925/HL/NHLBI NIH HHS/ -- RC2 HL-102926/HL/NHLBI NIH HHS/ -- RC2 HL-103010/HL/NHLBI NIH HHS/ -- RC2 HL102926/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 6;337(6090):64-9. doi: 10.1126/science.1219240.

    Ecological context influences epidemic size and parasite-driven evolution (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-31
    Description: The occurrence and magnitude of disease outbreaks can strongly influence host evolution. In particular, when hosts face a resistance-fecundity trade-off, they might evolve increased resistance to infection during larger epidemics but increased susceptibility during smaller ones. We tested this theoretical prediction by using a zooplankton-yeast host-parasite system in which ecological factors determine epidemic size. Lakes with high productivity and low predation pressure had large yeast epidemics; during these outbreaks, hosts became more resistant to infection. However, with low productivity and high predation, epidemics remained small and hosts evolved increased susceptibility. Thus, by modulating disease outbreaks, ecological context (productivity and predation) shaped host evolution during epidemics. Consequently, anthropogenic alteration of productivity and predation might strongly influence both ecological and evolutionary outcomes of disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duffy, Meghan A -- Ochs, Jessica Housley -- Penczykowski, Rachel M -- Civitello, David J -- Klausmeier, Christopher A -- Hall, Spencer R -- New York, N.Y. -- Science. 2012 Mar 30;335(6076):1636-8. doi: 10.1126/science.1215429.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biology, Georgia Institute of Technology, Atlanta, GA 30332-0230, USA. duffy@gatech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22461614" target="_blank"〉PubMed〈/a〉

    A Bruce effect in wild geladas (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-01
    Description: Female rodents are known to terminate pregnancies after exposure to unfamiliar males ("Bruce effect"). Although laboratory support abounds, direct evidence for a Bruce effect under natural conditions is lacking. Here, we report a strong Bruce effect in a wild primate, the gelada (Theropithecus gelada). Female geladas terminate 80% of pregnancies in the weeks after a dominant male is replaced. Further, data on interbirth intervals suggest that pregnancy termination offers fitness benefits for females whose offspring would otherwise be susceptible to infanticide. Taken together, data support the hypothesis that the Bruce effect can be an adaptive strategy for females.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Eila K -- Lu, Amy -- Bergman, Thore J -- Beehner, Jacinta C -- New York, N.Y. -- Science. 2012 Mar 9;335(6073):1222-5. doi: 10.1126/science.1213600.

    Pheromonal induction of spatial learning in mice (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-15
    Description: Many mammals use scent marking for sexual and competitive advertisement, but little is known about the mechanism by which scents are used to locate mates and competitors. We show that darcin, an involatile protein sex pheromone in male mouse urine, can rapidly condition preference for its remembered location among females and competitor males so that animals prefer to spend time in the site even when scent is absent. Learned spatial preference is conditioned through contact with darcin in a single trial and remembered for approximately 14 days. This pheromone-induced learning allows animals to relocate sites of particular social relevance and provides proof that pheromones such as darcin can be highly potent stimuli for social learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Sarah A -- Davidson, Amanda J -- McLean, Lynn -- Beynon, Robert J -- Hurst, Jane L -- BB/J002631/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC503897/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Dec 14;338(6113):1462-5. doi: 10.1126/science.1225638.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mammalian Behaviour and Evolution Group, Institute of Integrative Biology, University of Liverpool, Leahurst Campus, Neston CH64 7TE, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23239735" target="_blank"〉PubMed〈/a〉
