    Activity-dependent regulation of MEF2 transcription factors suppresses excitatory synapse number (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-18
    Description: In the mammalian nervous system, neuronal activity regulates the strength and number of synapses formed. The genetic program that coordinates this process is poorly understood. We show that myocyte enhancer factor 2 (MEF2) transcription factors suppressed excitatory synapse number in a neuronal activity- and calcineurin-dependent manner as hippocampal neurons formed synapses. In response to increased neuronal activity, calcium influx into neurons induced the activation of the calcium/calmodulin-regulated phosphatase calcineurin, which dephosphorylated and activated MEF2. When activated, MEF2 promoted the transcription of a set of genes, including arc and synGAP, that restrict synapse number. These findings define an activity-dependent transcriptional program that may control synapse number during development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flavell, Steven W -- Cowan, Christopher W -- Kim, Tae-Kyung -- Greer, Paul L -- Lin, Yingxi -- Paradis, Suzanne -- Griffith, Eric C -- Hu, Linda S -- Chen, Chinfei -- Greenberg, Michael E -- AG05870/AG/NIA NIH HHS/ -- HD18655/HD/NICHD NIH HHS/ -- NS28829/NS/NINDS NIH HHS/ -- R01 EY013613/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1008-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurobiology Program, Children's Hospital, and Departments of Neurology and Neurobiology, Harvard Medical School, 300 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484497" target="_blank"〉PubMed〈/a〉

    A dynamic marine calcium cycle during the past 28 million years (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-12-17
    Description: Multiple lines of evidence have shown that the isotopic composition and concentration of calcium in seawater have changed over the past 28 million years. A high-resolution, continuous seawater calcium isotope ratio curve from marine (pelagic) barite reveals distinct features in the evolution of the seawater calcium isotopic ratio suggesting changes in seawater calcium concentrations. The most pronounced increase in the delta44/40Ca value of seawater (of 0.3 per mil) occurred over roughly 4 million years following a period of low values around 13 million years ago. The major change in marine calcium corresponds to a climatic transition and global change in the carbon cycle and suggests a reorganization of the global biogeochemical system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffith, Elizabeth M -- Paytan, Adina -- Caldeira, Ken -- Bullen, Thomas D -- Thomas, Ellen -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1671-4. doi: 10.1126/science.1163614.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geological and Environmental Sciences, Stanford University, Building 320, Room 118, Stanford, CA 94305, USA. egriffith@ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19074345" target="_blank"〉PubMed〈/a〉

    Description: The smoggy stratosphere of Saturn's largest moon, Titan, veils its surface from view, except at narrow wavelengths centered at 0.83, 0.94, 1.07, 1.28, 1.58, 2.0, 2.9, and 5.0 micrometers. We derived a spectrum of Titan's surface within these "windows" and detected features characteristic of water ice. Therefore, despite the hundreds of meters of organic liquids and solids hypothesized to exist on Titan's surface, its icy bedrock lies extensively exposed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffith, Caitlin A -- Owen, Tobias -- Geballe, Thomas R -- Rayner, John -- Rannou, Pascal -- New York, N.Y. -- Science. 2003 Apr 25;300(5619):628-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Planetary Sciences, University of Arizona, 1629 East University Boulevard, Tucson, AZ 85721-0092, USA. griffith@lpl.arizona.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12714742" target="_blank"〉PubMed〈/a〉

    The Genome sequence of the SARS-associated coronavirus (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-06
    Description: We sequenced the 29,751-base genome of the severe acute respiratory syndrome (SARS)-associated coronavirus known as the Tor2 isolate. The genome sequence reveals that this coronavirus is only moderately related to other known coronaviruses, including two human coronaviruses, HCoV-OC43 and HCoV-229E. Phylogenetic analysis of the predicted viral proteins indicates that the virus does not closely resemble any of the three previously known groups of coronaviruses. The genome sequence will aid in the diagnosis of SARS virus infection in humans and potential animal hosts (using polymerase chain reaction and immunological tests), in the development of antivirals (including neutralizing antibodies), and in the identification of putative epitopes for vaccine development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marra, Marco A -- Jones, Steven J M -- Astell, Caroline R -- Holt, Robert A -- Brooks-Wilson, Angela -- Butterfield, Yaron S N -- Khattra, Jaswinder -- Asano, Jennifer K -- Barber, Sarah A -- Chan, Susanna Y -- Cloutier, Alison -- Coughlin, Shaun M -- Freeman, Doug -- Girn, Noreen -- Griffith, Obi L -- Leach, Stephen R -- Mayo, Michael -- McDonald, Helen -- Montgomery, Stephen B -- Pandoh, Pawan K -- Petrescu, Anca S -- Robertson, A Gordon -- Schein, Jacqueline E -- Siddiqui, Asim -- Smailus, Duane E -- Stott, Jeff M -- Yang, George S -- Plummer, Francis -- Andonov, Anton -- Artsob, Harvey -- Bastien, Nathalie -- Bernard, Kathy -- Booth, Timothy F -- Bowness, Donnie -- Czub, Martin -- Drebot, Michael -- Fernando, Lisa -- Flick, Ramon -- Garbutt, Michael -- Gray, Michael -- Grolla, Allen -- Jones, Steven -- Feldmann, Heinz -- Meyers, Adrienne -- Kabani, Amin -- Li, Yan -- Normand, Susan -- Stroher, Ute -- Tipples, Graham A -- Tyler, Shaun -- Vogrig, Robert -- Ward, Diane -- Watson, Brynn -- Brunham, Robert C -- Krajden, Mel -- Petric, Martin -- Skowronski, Danuta M -- Upton, Chris -- Roper, Rachel L -- New York, N.Y. -- Science. 2003 May 30;300(5624):1399-404.

    The evolution of Titan's mid-latitude clouds (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-10-22
    Description: Spectra from Cassini's Visual and Infrared Mapping Spectrometer reveal that the horizontal structure, height, and optical depth of Titan's clouds are highly dynamic. Vigorous cloud centers are seen to rise from the middle to the upper troposphere within 30 minutes and dissipate within the next hour. Their development indicates that Titan's clouds evolve convectively; dissipate through rain; and, over the next several hours, waft downwind to achieve their great longitude extents. These and other characteristics suggest that temperate clouds originate from circulation-induced convergence, in addition to a forcing at the surface associated with Saturn's tides, geology, and/or surface composition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffith, C A -- Penteado, P -- Baines, K -- Drossart, P -- Barnes, J -- Bellucci, G -- Bibring, J -- Brown, R -- Buratti, B -- Capaccioni, F -- Cerroni, P -- Clark, R -- Combes, M -- Coradini, A -- Cruikshank, D -- Formisano, V -- Jaumann, R -- Langevin, Y -- Matson, D -- McCord, T -- Mennella, V -- Nelson, R -- Nicholson, P -- Sicardy, B -- Sotin, C -- Soderblom, L A -- Kursinski, R -- New York, N.Y. -- Science. 2005 Oct 21;310(5747):474-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lunar and Planetary Laboratory, University of Arizona, Tucson, AZ 85721, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16239472" target="_blank"〉PubMed〈/a〉

    A 5-micron-bright spot on Titan: evidence for surface diversity (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-10-08
    Description: Observations from the Cassini Visual and Infrared Mapping Spectrometer show an anomalously bright spot on Titan located at 80 degrees W and 20 degrees S. This area is bright in reflected light at all observed wavelengths, but is most noticeable at 5 microns. The spot is associated with a surface albedo feature identified in images taken by the Cassini Imaging Science Subsystem. We discuss various hypotheses about the source of the spot, reaching the conclusion that the spot is probably due to variation in surface composition, perhaps associated with recent geophysical phenomena.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barnes, Jason W -- Brown, Robert H -- Turtle, Elizabeth P -- McEwen, Alfred S -- Lorenz, Ralph D -- Janssen, Michael -- Schaller, Emily L -- Brown, Michael E -- Buratti, Bonnie J -- Sotin, Christophe -- Griffith, Caitlin -- Clark, Roger -- Perry, Jason -- Fussner, Stephanie -- Barbara, John -- West, Richard -- Elachi, Charles -- Bouchez, Antonin H -- Roe, Henry G -- Baines, Kevin H -- Bellucci, Giancarlo -- Bibring, Jean-Pierre -- Capaccioni, Fabrizio -- Cerroni, Priscilla -- Combes, Michel -- Coradini, Angioletta -- Cruikshank, Dale P -- Drossart, Pierre -- Formisano, Vittorio -- Jaumann, Ralf -- Langevin, Yves -- Matson, Dennis L -- McCord, Thomas B -- Nicholson, Phillip D -- Sicardy, Bruno -- New York, N.Y. -- Science. 2005 Oct 7;310(5745):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lunar and Planetary Laboratory, University of Arizona, Tucson, AZ 85721, USA. jbarnes@lpl.arizona.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16210535" target="_blank"〉PubMed〈/a〉

    PDGFRA activating mutations in gastrointestinal stromal tumors (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-11
    Description: Most gastrointestinal stromal tumors (GISTs) have activating mutations in the KIT receptor tyrosine kinase, and most patients with GISTs respond well to Gleevec, which inhibits KIT kinase activity. Here we show that approximately 35% (14 of 40) of GISTs lacking KIT mutations have intragenic activation mutations in the related receptor tyrosine kinase, platelet-derived growth factor receptor alpha (PDGFRA). Tumors expressing KIT or PDGFRA oncoproteins were indistinguishable with respect to activation of downstream signaling intermediates and cytogenetic changes associated with tumor progression. Thus, KIT and PDGFRA mutations appear to be alternative and mutually exclusive oncogenic mechanisms in GISTs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heinrich, Michael C -- Corless, Christopher L -- Duensing, Anette -- McGreevey, Laura -- Chen, Chang-Jie -- Joseph, Nora -- Singer, Samuel -- Griffith, Diana J -- Haley, Andrea -- Town, Ajia -- Demetri, George D -- Fletcher, Christopher D M -- Fletcher, Jonathan A -- New York, N.Y. -- Science. 2003 Jan 31;299(5607):708-10.

    American Association for the Advancement of Science (AAAS)

    Description: Spectra from Cassini's Visual and Infrared Mapping Spectrometer reveal the presence of a vast tropospheric cloud on Titan at latitudes 51 degrees to 68 degrees north and all longitudes observed (10 degrees to 190 degrees west). The derived characteristics indicate that this cloud is composed of ethane and forms as a result of stratospheric subsidence and the particularly cool conditions near the moon's north pole. Preferential condensation of ethane, perhaps as ice, at Titan's poles during the winters may partially explain the lack of liquid ethane oceans on Titan's surface at middle and lower latitudes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffith, C A -- Penteado, P -- Rannou, P -- Brown, R -- Boudon, V -- Baines, K H -- Clark, R -- Drossart, P -- Buratti, B -- Nicholson, P -- McKay, C P -- Coustenis, A -- Negrao, A -- Jaumann, R -- New York, N.Y. -- Science. 2006 Sep 15;313(5793):1620-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lunar and Planetary Laboratory, University of Arizona, Tucson, AZ, 85721 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16973876" target="_blank"〉PubMed〈/a〉

    The 2.6 angstrom crystal structure of a human A2A adenosine receptor bound to an antagonist (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-10-04
    Description: The adenosine class of heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptors (GPCRs) mediates the important role of extracellular adenosine in many physiological processes and is antagonized by caffeine. We have determined the crystal structure of the human A2A adenosine receptor, in complex with a high-affinity subtype-selective antagonist, ZM241385, to 2.6 angstrom resolution. Four disulfide bridges in the extracellular domain, combined with a subtle repacking of the transmembrane helices relative to the adrenergic and rhodopsin receptor structures, define a pocket distinct from that of other structurally determined GPCRs. The arrangement allows for the binding of the antagonist in an extended conformation, perpendicular to the membrane plane. The binding site highlights an integral role for the extracellular loops, together with the helical core, in ligand recognition by this class of GPCRs and suggests a role for ZM241385 in restricting the movement of a tryptophan residue important in the activation mechanism of the class A receptors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2586971/" 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/PMC2586971/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jaakola, Veli-Pekka -- Griffith, Mark T -- Hanson, Michael A -- Cherezov, Vadim -- Chien, Ellen Y T -- Lane, J Robert -- Ijzerman, Adriaan P -- Stevens, Raymond C -- GM075915/GM/NIGMS NIH HHS/ -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073197-04/GM/NIGMS NIH HHS/ -- R01 GM089857/GM/NIGMS NIH HHS/ -- U54 GM074961/GM/NIGMS NIH HHS/ -- U54 GM074961-04/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Nov 21;322(5905):1211-7. doi: 10.1126/science.1164772.

    Dynamic processes governing lower-tropospheric HDO/H2O ratios as observed from space and ground (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-09-12
    Description: The hydrological cycle and its response to environmental variability such as temperature changes is of prime importance for climate reconstruction and prediction. We retrieved deuterated water/water (HDO/H2O) abundances using spaceborne absorption spectroscopy, providing an almost global perspective on the near-surface distribution of water vapor isotopologs. We observed an unexpectedly high HDO/H2O seasonality in the inner Sahel region, pointing to a strong isotopic depletion in the subsiding branch of the Hadley circulation and its misrepresentation in general circulation models. An extension of the analysis at high latitudes using ground-based observations of deltaD and a model study shows that dynamic processes can entirely compensate for temperature effects on the isotopic composition of precipitation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frankenberg, Christian -- Yoshimura, Kei -- Warneke, Thorsten -- Aben, Ilse -- Butz, Andre -- Deutscher, Nicholas -- Griffith, David -- Hase, Frank -- Notholt, Justus -- Schneider, Matthias -- Schrijver, Hans -- Rockmann, Thomas -- New York, N.Y. -- Science. 2009 Sep 11;325(5946):1374-7. doi: 10.1126/science.1173791.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉SRON-Netherlands Institute for Space Research, Sorbonnelaan 2, 3584CA Utrecht, Netherlands.
