    PRDM9 is a major determinant of meiotic recombination hotspots in humans and mice (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-02
    Description: Meiotic recombination events cluster into narrow segments of the genome, defined as hotspots. Here, we demonstrate that a major player for hotspot specification is the Prdm9 gene. First, two mouse strains that differ in hotspot usage are polymorphic for the zinc finger DNA binding array of PRDM9. Second, the human consensus PRDM9 allele is predicted to recognize the 13-mer motif enriched at human hotspots; this DNA binding specificity is verified by in vitro studies. Third, allelic variants of PRDM9 zinc fingers are significantly associated with variability in genome-wide hotspot usage among humans. Our results provide a molecular basis for the distribution of meiotic recombination in mammals, in which the binding of PRDM9 to specific DNA sequences targets the initiation of recombination at specific locations in the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295902/" 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/PMC4295902/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baudat, F -- Buard, J -- Grey, C -- Fledel-Alon, A -- Ober, C -- Przeworski, M -- Coop, G -- de Massy, B -- 03S1/PHS HHS/ -- GM83098/GM/NIGMS NIH HHS/ -- HD21244/HD/NICHD NIH HHS/ -- HL085197/HL/NHLBI NIH HHS/ -- R01 GM083098/GM/NIGMS NIH HHS/ -- R01 HD021244/HD/NICHD NIH HHS/ -- R01 HL085197/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):836-40. doi: 10.1126/science.1183439.

    Contribution of semi-arid forests to the climate system (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-23
    Description: Forests both take up CO2 and enhance absorption of solar radiation, with contrasting effects on global temperature. Based on a 9-year study in the forests' dry timberline, we show that substantial carbon sequestration (cooling effect) is maintained in the large dry transition zone (precipitation from 200 to 600 millimeters) by shifts in peak photosynthetic activities from summer to early spring, and this is counteracted by longwave radiation (L) suppression (warming effect), doubling the forestation shortwave (S) albedo effect. Several decades of carbon accumulation are required to balance the twofold S + L effect. Desertification over the past several decades, however, contributed negative forcing at Earth's surface equivalent to approximately 20% of the global anthropogenic CO2 effect over the same period, moderating warming trends.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rotenberg, Eyal -- Yakir, Dan -- New York, N.Y. -- Science. 2010 Jan 22;327(5964):451-4. doi: 10.1126/science.1179998.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Environmental Sciences and Energy Research, Weizmann Institute of Science, Rehovot 76100, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20093470" target="_blank"〉PubMed〈/a〉

    The ligase PIAS1 restricts natural regulatory T cell differentiation by epigenetic repression (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-23
    Description: CD4(+)Foxp3(+) regulatory T (T(reg)) cells are important for maintaining immune tolerance. Understanding the molecular mechanism that regulates T(reg) differentiation will facilitate the development of effective therapeutic strategies against autoimmune diseases. We report here that the SUMO E3 ligase PIAS1 restricts the differentiation of natural T(reg) cells by maintaining a repressive chromatin state of the Foxp3 promoter. PIAS1 acts by binding to the Foxp3 promoter to recruit DNA methyltransferases and heterochromatin protein 1 for epigenetic modifications. Pias1 deletion caused promoter demethylation, reduced histone H3 methylation at Lys(9), and enhanced promoter accessibility. Consistently, Pias1(-/-) mice displayed an increased natural T(reg) cell population and were resistant to the development of experimental autoimmune encephalomyelitis. Our studies have identified an epigenetic mechanism that negatively regulates the differentiation of natural T(reg) cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3043201/" 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/PMC3043201/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Bin -- Tahk, Samuel -- Yee, Kathleen M -- Fan, Guoping -- Shuai, Ke -- K01 AR52717-01/AR/NIAMS NIH HHS/ -- R01 AI063286/AI/NIAID NIH HHS/ -- R01 AI063286-05/AI/NIAID NIH HHS/ -- R01 GM085797/GM/NIGMS NIH HHS/ -- R01 GM085797-03/GM/NIGMS NIH HHS/ -- R01AI063286/AI/NIAID NIH HHS/ -- R01GM085797/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 22;330(6003):521-5. doi: 10.1126/science.1193787.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology-Oncology, Department of Medicine, 11-934 Factor Building, 10833 Le Conte Avenue, University of California, Los Angeles, Los Angeles, CA 90095, USA. bliu@ucla.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20966256" target="_blank"〉PubMed〈/a〉

    Identification of RACK1 and protein kinase Calpha as integral components of the mammalian circadian clock (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-23
    Description: At the core of the mammalian circadian clock is a negative feedback loop in which the dimeric transcription factor CLOCK-BMAL1 drives processes that in turn suppress its transcriptional activity. To gain insight into the mechanisms of circadian feedback, we analyzed mouse protein complexes containing BMAL1. Receptor for activated C kinase-1 (RACK1) and protein kinase C-alpha (PKCalpha) were recruited in a circadian manner into a nuclear BMAL1 complex during the negative feedback phase of the cycle. Overexpression of RACK1 and PKCalpha suppressed CLOCK-BMAL1 transcriptional activity, and RACK1 stimulated phosphorylation of BMAL1 by PKCalpha in vitro. Depletion of endogenous RACK1 or PKCalpha from fibroblasts shortened the circadian period, demonstrating that both molecules function in the clock oscillatory mechanism. Thus, the classical PKC signaling pathway is not limited to relaying external stimuli but is rhythmically activated by internal processes, forming an integral part of the circadian feedback loop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robles, Maria S -- Boyault, Cyril -- Knutti, Darko -- Padmanabhan, Kiran -- Weitz, Charles J -- New York, N.Y. -- Science. 2010 Jan 22;327(5964):463-6. doi: 10.1126/science.1180067.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20093473" target="_blank"〉PubMed〈/a〉

    The role of discharge variation in scaling of drainage area and food chain length in rivers (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-16
    Description: Food chain length (FCL) is a fundamental component of food web structure. Studies in a variety of ecosystems suggest that FCL is determined by energy supply, environmental stability, and/or ecosystem size, but the nature of the relationship between environmental stability and FCL, and the mechanism linking ecosystem size to FCL, remain unclear. Here we show that FCL increases with drainage area and decreases with hydrologic variability and intermittency across 36 North American rivers. Our analysis further suggests that hydrologic variability is the mechanism underlying the correlation between ecosystem size and FCL in rivers. Ecosystem size lengthens river food chains by integrating and attenuating discharge variation through stream networks, thereby enhancing environmental stability in larger river systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sabo, John L -- Finlay, Jacques C -- Kennedy, Theodore -- Post, David M -- New York, N.Y. -- Science. 2010 Nov 12;330(6006):965-7. doi: 10.1126/science.1196005.

    Glucose and weight control in mice with a designed ghrelin O-acyltransferase inhibitor (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-11-26
    Description: Ghrelin is a gastric peptide hormone that stimulates weight gain in vertebrates. The biological activities of ghrelin require octanoylation of the peptide on Ser(3), an unusual posttranslational modification that is catalyzed by the enzyme ghrelin O-acyltransferase (GOAT). Here, we describe the design, synthesis, and characterization of GO-CoA-Tat, a peptide-based bisubstrate analog that antagonizes GOAT. GO-CoA-Tat potently inhibits GOAT in vitro, in cultured cells, and in mice. Intraperitoneal administration of GO-CoA-Tat improves glucose tolerance and reduces weight gain in wild-type mice but not in ghrelin-deficient mice, supporting the concept that its beneficial metabolic effects are due specifically to GOAT inhibition. In addition to serving as a research tool for mapping ghrelin actions, GO-CoA-Tat may help pave the way for clinical targeting of GOAT in metabolic diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3068526/" 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/PMC3068526/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barnett, Brad P -- Hwang, Yousang -- Taylor, Martin S -- Kirchner, Henriette -- Pfluger, Paul T -- Bernard, Vincent -- Lin, Yu-yi -- Bowers, Erin M -- Mukherjee, Chandrani -- Song, Woo-Jin -- Longo, Patti A -- Leahy, Daniel J -- Hussain, Mehboob A -- Tschop, Matthias H -- Boeke, Jef D -- Cole, Philip A -- P01 CA016519/CA/NCI NIH HHS/ -- P01 CA016519-35/CA/NCI NIH HHS/ -- P30 DK079637/DK/NIDDK NIH HHS/ -- P60 DK079637/DK/NIDDK NIH HHS/ -- P60 DK079637-05/DK/NIDDK NIH HHS/ -- R01 DK081472/DK/NIDDK NIH HHS/ -- R01 DK081472-01A1/DK/NIDDK NIH HHS/ -- R01 DK081472-02/DK/NIDDK NIH HHS/ -- R01 DK081472-03/DK/NIDDK NIH HHS/ -- R01 GM062437/GM/NIGMS NIH HHS/ -- R01 GM062437-04/GM/NIGMS NIH HHS/ -- R01 GM062437-11/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 17;330(6011):1689-92. doi: 10.1126/science.1196154.

    Darwinian evolution of prions in cell culture (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-02
    Description: Prions are infectious proteins consisting mainly of PrP(Sc), a beta sheet-rich conformer of the normal host protein PrP(C), and occur in different strains. Strain identity is thought to be encoded by PrP(Sc) conformation. We found that biologically cloned prion populations gradually became heterogeneous by accumulating "mutants," and selective pressures resulted in the emergence of different mutants as major constituents of the evolving population. Thus, when transferred from brain to cultured cells, "cell-adapted" prions outcompeted their "brain-adapted" counterparts, and the opposite occurred when prions were returned from cells to brain. Similarly, the inhibitor swainsonine selected for a resistant substrain, whereas, in its absence, the susceptible substrain outgrew its resistant counterpart. Prions, albeit devoid of a nucleic acid genome, are thus subject to mutation and selective amplification.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2848070/" 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/PMC2848070/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Jiali -- Browning, Shawn -- Mahal, Sukhvir P -- Oelschlegel, Anja M -- Weissmann, Charles -- NS059543/NS/NINDS NIH HHS/ -- R01 NS059543/NS/NINDS NIH HHS/ -- R01 NS059543-01/NS/NINDS NIH HHS/ -- R01 NS059543-02/NS/NINDS NIH HHS/ -- R01 NS067214/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):869-72. doi: 10.1126/science.1183218.

    Activation of beta-catenin in dendritic cells regulates immunity versus tolerance in the intestine (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-08-14
    Description: Dendritic cells (DCs) play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens. However, the intracellular signaling networks that program DCs to become tolerogenic remain unknown. We report here that the Wnt-beta-catenin signaling in intestinal dendritic cells regulates the balance between inflammatory versus regulatory responses in the gut. beta-catenin in intestinal dendritic cells was required for the expression of anti-inflammatory mediators such as retinoic acid-metabolizing enzymes, interleukin-10, and transforming growth factor-beta, and the stimulation of regulatory T cell induction while suppressing inflammatory effector T cells. Furthermore, ablation of beta-catenin expression in DCs enhanced inflammatory responses and disease in a mouse model of inflammatory bowel disease. Thus, beta-catenin signaling programs DCs to a tolerogenic state, limiting the inflammatory response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3732486/" 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/PMC3732486/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Manicassamy, Santhakumar -- Reizis, Boris -- Ravindran, Rajesh -- Nakaya, Helder -- Salazar-Gonzalez, Rosa Maria -- Wang, Yi-Chong -- Pulendran, Bali -- HHSN266 200700006C/PHS HHS/ -- N01 AI50019/AI/NIAID NIH HHS/ -- N01 AI50025/AI/NIAID NIH HHS/ -- R01 AI048638/AI/NIAID NIH HHS/ -- R01 AI056499/AI/NIAID NIH HHS/ -- R01 DK057665/DK/NIDDK NIH HHS/ -- R01DK057665,/DK/NIDDK NIH HHS/ -- R37 AI048638/AI/NIAID NIH HHS/ -- R37 DK057665/DK/NIDDK NIH HHS/ -- R37AI48638,/AI/NIAID NIH HHS/ -- U19 AI057266/AI/NIAID NIH HHS/ -- U19AI057266,/AI/NIAID NIH HHS/ -- U54 AI057157/AI/NIAID NIH HHS/ -- U54AI057157/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 13;329(5993):849-53. doi: 10.1126/science.1188510.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Emory Vaccine Center, and Yerkes National Primate Research Center, 954 Gatewood Road, Atlanta, GA 30329, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20705860" target="_blank"〉PubMed〈/a〉

    Efficient atmospheric cleansing of oxidized organic trace gases by vegetation (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-23
    Description: The biosphere is the major source and sink of nonmethane volatile organic compounds (VOCs) in the atmosphere. Gas-phase chemical reactions initiate the removal of these compounds from the atmosphere, which ultimately proceeds via deposition at the surface or direct oxidation to carbon monoxide or carbon dioxide. We performed ecosystem-scale flux measurements that show that the removal of oxygenated VOC via dry deposition is substantially larger than is currently assumed for deciduous ecosystems. Laboratory experiments indicate efficient enzymatic conversion and potential up-regulation of various stress-related genes, leading to enhanced uptake rates as a response to ozone and methyl vinyl ketone exposure or mechanical wounding. A revised scheme for the uptake of oxygenated VOCs, incorporated into a global chemistry-transport model, predicts appreciable regional changes in annual dry deposition fluxes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karl, T -- Harley, P -- Emmons, L -- Thornton, B -- Guenther, A -- Basu, C -- Turnipseed, A -- Jardine, K -- New York, N.Y. -- Science. 2010 Nov 5;330(6005):816-9. doi: 10.1126/science.1192534.

    Cyclooxygenase-2 controls energy homeostasis in mice by de novo recruitment of brown adipocytes (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-05-08
    Description: Obesity results from chronic energy surplus and excess lipid storage in white adipose tissue (WAT). In contrast, brown adipose tissue (BAT) efficiently burns lipids through adaptive thermogenesis. Studying mouse models, we show that cyclooxygenase (COX)-2, a rate-limiting enzyme in prostaglandin (PG) synthesis, is a downstream effector of beta-adrenergic signaling in WAT and is required for the induction of BAT in WAT depots. PG shifted the differentiation of defined mesenchymal progenitors toward a brown adipocyte phenotype. Overexpression of COX-2 in WAT induced de novo BAT recruitment in WAT, increased systemic energy expenditure, and protected mice against high-fat diet-induced obesity. Thus, COX-2 appears integral to de novo BAT recruitment, which suggests that the PG pathway regulates systemic energy homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vegiopoulos, Alexandros -- Muller-Decker, Karin -- Strzoda, Daniela -- Schmitt, Iris -- Chichelnitskiy, Evgeny -- Ostertag, Anke -- Berriel Diaz, Mauricio -- Rozman, Jan -- Hrabe de Angelis, Martin -- Nusing, Rolf M -- Meyer, Carola W -- Wahli, Walter -- Klingenspor, Martin -- Herzig, Stephan -- New York, N.Y. -- Science. 2010 May 28;328(5982):1158-61. doi: 10.1126/science.1186034.

    G protein subunit Galpha13 binds to integrin alphaIIbbeta3 and mediates integrin "outside-in" signaling (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-16
    Description: Integrins mediate cell adhesion to the extracellular matrix and transmit signals within the cell that stimulate cell spreading, retraction, migration, and proliferation. The mechanism of integrin outside-in signaling has been unclear. We found that the heterotrimeric guanine nucleotide-binding protein (G protein) Galpha13 directly bound to the integrin beta3 cytoplasmic domain and that Galpha13-integrin interaction was promoted by ligand binding to the integrin alphaIIbbeta3 and by guanosine triphosphate (GTP) loading of Galpha13. Interference of Galpha13 expression or a myristoylated fragment of Galpha13 that inhibited interaction of alphaIIbbeta3 with Galpha13 diminished activation of protein kinase c-Src and stimulated the small guanosine triphosphatase RhoA, consequently inhibiting cell spreading and accelerating cell retraction. We conclude that integrins are noncanonical Galpha13-coupled receptors that provide a mechanism for dynamic regulation of RhoA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2842917/" 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/PMC2842917/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gong, Haixia -- Shen, Bo -- Flevaris, Panagiotis -- Chow, Christina -- Lam, Stephen C-T -- Voyno-Yasenetskaya, Tatyana A -- Kozasa, Tohru -- Du, Xiaoping -- GM061454/GM/NIGMS NIH HHS/ -- GM074001/GM/NIGMS NIH HHS/ -- HL062350/HL/NHLBI NIH HHS/ -- HL068819/HL/NHLBI NIH HHS/ -- HL080264/HL/NHLBI NIH HHS/ -- R01 GM061454/GM/NIGMS NIH HHS/ -- R01 GM061454-09/GM/NIGMS NIH HHS/ -- R01 GM074001/GM/NIGMS NIH HHS/ -- R01 GM074001-02/GM/NIGMS NIH HHS/ -- R01 HL062350/HL/NHLBI NIH HHS/ -- R01 HL062350-09/HL/NHLBI NIH HHS/ -- R01 HL068819/HL/NHLBI NIH HHS/ -- R01 HL068819-08/HL/NHLBI NIH HHS/ -- R01 HL080264/HL/NHLBI NIH HHS/ -- R01 HL080264-04/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):340-3. doi: 10.1126/science.1174779.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Illinois at Chicago, 835 South Wolcott Avenue, Room E403, Chicago, IL 60612, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075254" target="_blank"〉PubMed〈/a〉

    Mcl-1 is essential for germinal center formation and B cell memory (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-12
    Description: Lymphocyte survival during immune responses is controlled by the relative expression of pro- and anti-apoptotic molecules, regulating the magnitude, quality, and duration of the response. We investigated the consequences of deleting genes encoding the anti-apoptotic molecules Mcl1 and Bcl2l1 (Bcl-x(L)) from B cells using an inducible system synchronized with expression of activation-induced cytidine deaminase (Aicda) after immunization. This revealed Mcl1 and not Bcl2l1 to be indispensable for the formation and persistence of germinal centers (GCs). Limiting Mcl1 expression reduced the magnitude of the GC response with an equivalent, but not greater, effect on memory B cell formation and no effect on persistence. Our results identify Mcl1 as the main anti-apoptotic regulator of activated B cell survival and suggest distinct mechanisms controlling survival of GC and memory B cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2991396/" 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/PMC2991396/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vikstrom, Ingela -- Carotta, Sebastian -- Luthje, Katja -- Peperzak, Victor -- Jost, Philipp J -- Glaser, Stefan -- Busslinger, Meinrad -- Bouillet, Philippe -- Strasser, Andreas -- Nutt, Stephen L -- Tarlinton, David M -- CA43540/CA/NCI NIH HHS/ -- CA80188/CA/NCI NIH HHS/ -- R01 CA043540/CA/NCI NIH HHS/ -- R01 CA043540-22/CA/NCI NIH HHS/ -- R01 CA080188-08/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Nov 19;330(6007):1095-9. doi: 10.1126/science.1191793.

    Prdm9 controls activation of mammalian recombination hotspots (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-02
    Description: Mammalian meiotic recombination, which preferentially occurs at specialized sites called hotspots, ensures the orderly segregation of meiotic chromosomes and creates genetic variation among offspring. A locus on mouse chromosome 17, which controls activation of recombination at multiple distant hotspots, has been mapped within a 181-kilobase interval, three of whose genes can be eliminated as candidates. The remaining gene, Prdm9, codes for a zinc finger containing histone H3K4 trimethylase that is expressed in early meiosis and whose deficiency results in sterility in both sexes. Mus musculus exhibits five alleles of Prdm9; human populations exhibit two predominant alleles and multiple minor alleles. The identification of Prdm9 as a protein regulating mammalian recombination hotspots initiates molecular studies of this important biological control system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2821451/" 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/PMC2821451/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parvanov, Emil D -- Petkov, Petko M -- Paigen, Kenneth -- 076468/PHS HHS/ -- 078452/PHS HHS/ -- 083408/PHS HHS/ -- CA 34196/CA/NCI NIH HHS/ -- GM 078643/GM/NIGMS NIH HHS/ -- P30 CA034196-26/CA/NCI NIH HHS/ -- P50 GM076468/GM/NIGMS NIH HHS/ -- P50 GM076468-030004/GM/NIGMS NIH HHS/ -- R01 GM078452/GM/NIGMS NIH HHS/ -- R01 GM078452-02/GM/NIGMS NIH HHS/ -- R01 GM078643/GM/NIGMS NIH HHS/ -- R01 GM078643-03/GM/NIGMS NIH HHS/ -- R01 GM083408/GM/NIGMS NIH HHS/ -- R01 GM083408-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):835. doi: 10.1126/science.1181495.

    Asymmetric density dependence shapes species abundances in a tropical tree community (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-06-26
    Description: The factors determining species commonness and rarity are poorly understood, particularly in highly diverse communities. Theory predicts that interactions with neighbors of the same (conspecific) and other (heterospecific) species can influence a species' relative abundance, but empirical tests are lacking. By using a hierarchical model of survival for more than 30,000 seedlings of 180 tropical tree species on Barro Colorado Island, Panama, we tested whether species' sensitivity to neighboring individuals relates to their relative abundance in the community. We found wide variation among species in the effect of conspecific, but not heterospecific, neighbors on survival, and we found a significant relationship between the strength of conspecific neighbor effects and species abundance. Specifically, rare species suffered more from the presence of conspecific neighbors than common species did, suggesting that conspecific density dependence shapes species abundances in diverse communities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Comita, Liza S -- Muller-Landau, Helene C -- Aguilar, Salomon -- Hubbell, Stephen P -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):330-2. doi: 10.1126/science.1190772.

    Details
    Publication Date: 2010-07-22
    Description: Since the collapse of the pelagic fisheries off southwest Africa in the late 1960s, jellyfish biomass has increased and the structure of the Benguelan fish community has shifted, making the bearded goby (Sufflogobius bibarbatus) the new predominant prey species. Despite increased predation pressure and a harsh environment, the gobies are thriving. Here we show that physiological adaptations and antipredator and foraging behaviors underpin the success of these fish. In particular, body-tissue isotope signatures reveal that gobies consume jellyfish and sulphidic diatomaceous mud, transferring "dead-end" resources back into the food chain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Utne-Palm, Anne C -- Salvanes, Anne G V -- Currie, Bronwen -- Kaartvedt, Stein -- Nilsson, Goran E -- Braithwaite, Victoria A -- Stecyk, Jonathan A W -- Hundt, Matthias -- van der Bank, Megan -- Flynn, Bradley -- Sandvik, Guro K -- Klevjer, Thor A -- Sweetman, Andrew K -- Bruchert, Volker -- Pittman, Karin -- Peard, Kathleen R -- Lunde, Ida G -- Strandabo, Ronnaug A U -- Gibbons, Mark J -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):333-6. doi: 10.1126/science.1190708.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Bergen, Bergen, Norway. anne.palm@bio.uib.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20647468" target="_blank"〉PubMed〈/a〉

    Sex-specific parent-of-origin allelic expression in the mouse brain (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-07-10
    Description: Genomic imprinting results in preferential gene expression from paternally versus maternally inherited chromosomes. We used a genome-wide approach to uncover sex-specific parent-of-origin allelic effects in the adult mouse brain. Our study identified preferential selection of the maternally inherited X chromosome in glutamatergic neurons of the female cortex. Moreover, analysis of the cortex and hypothalamus identified 347 autosomal genes with sex-specific imprinting features. In the hypothalamus, sex-specific imprinted genes were mostly found in females, which suggests parental influence over the hypothalamic function of daughters. We show that interleukin-18, a gene linked to diseases with sex-specific prevalence, is subject to complex, regional, and sex-specific parental effects in the brain. Parent-of-origin effects thus provide new avenues for investigation of sexual dimorphism in brain function and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997643/" 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/PMC2997643/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregg, Christopher -- Zhang, Jiangwen -- Butler, James E -- Haig, David -- Dulac, Catherine -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):682-5. doi: 10.1126/science.1190831.

    Substrate elasticity regulates skeletal muscle stem cell self-renewal in culture (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-07-22
    Description: Stem cells that naturally reside in adult tissues, such as muscle stem cells (MuSCs), exhibit robust regenerative capacity in vivo that is rapidly lost in culture. Using a bioengineered substrate to recapitulate key biophysical and biochemical niche features in conjunction with a highly automated single-cell tracking algorithm, we show that substrate elasticity is a potent regulator of MuSC fate in culture. Unlike MuSCs on rigid plastic dishes (approximately 10(6) kilopascals), MuSCs cultured on soft hydrogel substrates that mimic the elasticity of muscle (12 kilopascals) self-renew in vitro and contribute extensively to muscle regeneration when subsequently transplanted into mice and assayed histologically and quantitatively by noninvasive bioluminescence imaging. Our studies provide novel evidence that by recapitulating physiological tissue rigidity, propagation of adult muscle stem cells is possible, enabling future cell-based therapies for muscle-wasting diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2929271/" 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/PMC2929271/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilbert, P M -- Havenstrite, K L -- Magnusson, K E G -- Sacco, A -- Leonardi, N A -- Kraft, P -- Nguyen, N K -- Thrun, S -- Lutolf, M P -- Blau, H M -- 2 T32 HD007249/HD/NICHD NIH HHS/ -- 52005886/Howard Hughes Medical Institute/ -- AG009521/AG/NIA NIH HHS/ -- AG020961/AG/NIA NIH HHS/ -- CA09151/CA/NCI NIH HHS/ -- HL096113/HL/NHLBI NIH HHS/ -- R01 AG009521/AG/NIA NIH HHS/ -- R01 AG009521-25/AG/NIA NIH HHS/ -- R01 AG020961/AG/NIA NIH HHS/ -- R01 AG020961-06A2/AG/NIA NIH HHS/ -- R01 AG020961-07/AG/NIA NIH HHS/ -- R01 HL096113/HL/NHLBI NIH HHS/ -- R01 HL096113-03/HL/NHLBI NIH HHS/ -- T32 CA009151/CA/NCI NIH HHS/ -- T32 CA009151-35/CA/NCI NIH HHS/ -- T32 HD007249/HD/NICHD NIH HHS/ -- T32 HD007249-25/HD/NICHD NIH HHS/ -- U01 HL100397/HL/NHLBI NIH HHS/ -- U01 HL100397-01/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 27;329(5995):1078-81. doi: 10.1126/science.1191035.

    Description: Shelterin is an essential telomeric protein complex that prevents DNA damage signaling and DNA repair at mammalian chromosome ends. Here we report on the role of the TRF2-interacting factor Rap1, a conserved shelterin subunit of unknown function. We removed Rap1 from mouse telomeres either through gene deletion or by replacing TRF2 with a mutant that does not bind Rap1. Rap1 was dispensable for the essential functions of TRF2--repression of ATM kinase signaling and nonhomologous end joining (NHEJ)--and mice lacking telomeric Rap1 were viable and fertile. However, Rap1 was critical for the repression of homology-directed repair (HDR), which can alter telomere length. The data reveal that HDR at telomeres can take place in the absence of DNA damage foci and underscore the functional compartmentalization within shelterin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2864730/" 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/PMC2864730/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sfeir, Agnel -- Kabir, Shaheen -- van Overbeek, Megan -- Celli, Giulia B -- de Lange, Titia -- AG016642/AG/NIA NIH HHS/ -- GM049046/GM/NIGMS NIH HHS/ -- R01 AG016642/AG/NIA NIH HHS/ -- R01 AG016642-01/AG/NIA NIH HHS/ -- R01 AG016642-02/AG/NIA NIH HHS/ -- R01 AG016642-03/AG/NIA NIH HHS/ -- R01 AG016642-04/AG/NIA NIH HHS/ -- R01 AG016642-05/AG/NIA NIH HHS/ -- R01 AG016642-06/AG/NIA NIH HHS/ -- R01 AG016642-07/AG/NIA NIH HHS/ -- R01 AG016642-08/AG/NIA NIH HHS/ -- R01 AG016642-09/AG/NIA NIH HHS/ -- R01 AG016642-10/AG/NIA NIH HHS/ -- R01 AG016642-11/AG/NIA NIH HHS/ -- R01 GM049046/GM/NIGMS NIH HHS/ -- R01 GM049046-07/GM/NIGMS NIH HHS/ -- R01 GM049046-08/GM/NIGMS NIH HHS/ -- R01 GM049046-09/GM/NIGMS NIH HHS/ -- R01 GM049046-10/GM/NIGMS NIH HHS/ -- R01 GM049046-11/GM/NIGMS NIH HHS/ -- R01 GM049046-12/GM/NIGMS NIH HHS/ -- R37 GM049046/GM/NIGMS NIH HHS/ -- R37 GM049046-13/GM/NIGMS NIH HHS/ -- R37 GM049046-14/GM/NIGMS NIH HHS/ -- R37 GM049046-15/GM/NIGMS NIH HHS/ -- R37 GM049046-16/GM/NIGMS NIH HHS/ -- R37 GM049046-17/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1657-61. doi: 10.1126/science.1185100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Rockefeller University, 1230 York Avenue, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20339076" target="_blank"〉PubMed〈/a〉

    Sfrp5 is an anti-inflammatory adipokine that modulates metabolic dysfunction in obesity (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-06-19
    Description: Adipose tissue secretes proteins referred to as adipokines, many of which promote inflammation and disrupt glucose homeostasis. Here we show that secreted frizzled-related protein 5 (Sfrp5), a protein previously linked to the Wnt signaling pathway, is an anti-inflammatory adipokine whose expression is perturbed in models of obesity and type 2 diabetes. Sfrp5-deficient mice fed a high-calorie diet developed severe glucose intolerance and hepatic steatosis, and their adipose tissue showed an accumulation of activated macrophages that was associated with activation of the c-Jun N-terminal kinase signaling pathway. Adenovirus-mediated delivery of Sfrp5 to mouse models of obesity ameliorated glucose intolerance and hepatic steatosis. Thus, in the setting of obesity, Sfrp5 secretion by adipocytes exerts salutary effects on metabolic dysfunction by controlling inflammatory cells within adipose tissue.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3132938/" 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/PMC3132938/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ouchi, Noriyuki -- Higuchi, Akiko -- Ohashi, Koji -- Oshima, Yuichi -- Gokce, Noyan -- Shibata, Rei -- Akasaki, Yuichi -- Shimono, Akihiko -- Walsh, Kenneth -- AG15052/AG/NIA NIH HHS/ -- AG34972/AG/NIA NIH HHS/ -- HL81587/HL/NHLBI NIH HHS/ -- HL86785/HL/NHLBI NIH HHS/ -- P01 HL081587/HL/NHLBI NIH HHS/ -- P01 HL081587-05/HL/NHLBI NIH HHS/ -- R01 AG015052/AG/NIA NIH HHS/ -- R01 AG015052-06/AG/NIA NIH HHS/ -- R01 AG034972/AG/NIA NIH HHS/ -- R01 AG034972-03/AG/NIA NIH HHS/ -- R01 HL086785/HL/NHLBI NIH HHS/ -- R01 HL086785-19/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):454-7. doi: 10.1126/science.1188280.

    Essential role of the histone methyltransferase G9a in cocaine-induced plasticity (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-09
    Description: Cocaine-induced alterations in gene expression cause changes in neuronal morphology and behavior that may underlie cocaine addiction. In mice, we identified an essential role for histone 3 lysine 9 (H3K9) dimethylation and the lysine dimethyltransferase G9a in cocaine-induced structural and behavioral plasticity. Repeated cocaine administration reduced global levels of H3K9 dimethylation in the nucleus accumbens. This reduction in histone methylation was mediated through the repression of G9a in this brain region, which was regulated by the cocaine-induced transcription factor DeltaFosB. Using conditional mutagenesis and viral-mediated gene transfer, we found that G9a down-regulation increased the dendritic spine plasticity of nucleus accumbens neurons and enhanced the preference for cocaine, thereby establishing a crucial role for histone methylation in the long-term actions of cocaine.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820240/" 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/PMC2820240/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maze, Ian -- Covington, Herbert E 3rd -- Dietz, David M -- LaPlant, Quincey -- Renthal, William -- Russo, Scott J -- Mechanic, Max -- Mouzon, Ezekiell -- Neve, Rachael L -- Haggarty, Stephen J -- Ren, Yanhua -- Sampath, Srihari C -- Hurd, Yasmin L -- Greengard, Paul -- Tarakhovsky, Alexander -- Schaefer, Anne -- Nestler, Eric J -- P01 DA008227/DA/NIDA NIH HHS/ -- P01 DA008227-120001/DA/NIDA NIH HHS/ -- P01 DA008227-129001/DA/NIDA NIH HHS/ -- P01 DA008227-13/DA/NIDA NIH HHS/ -- P01 DA008227-14/DA/NIDA NIH HHS/ -- P01 DA008227-15/DA/NIDA NIH HHS/ -- P01 DA008227-16/DA/NIDA NIH HHS/ -- P01 DA008227-170003/DA/NIDA NIH HHS/ -- P01 DA008227-180003/DA/NIDA NIH HHS/ -- P01 DA010044/DA/NIDA NIH HHS/ -- P01 DA010044-14/DA/NIDA NIH HHS/ -- P01 DA010044-140005/DA/NIDA NIH HHS/ -- P01 DA010044-149002/DA/NIDA NIH HHS/ -- P01 DA010044-14S1/DA/NIDA NIH HHS/ -- P01 DA010044-14S10005/DA/NIDA NIH HHS/ -- P01 DA010044-14S19002/DA/NIDA NIH HHS/ -- P01 DA010044-15/DA/NIDA NIH HHS/ -- P01 DA010044-150005/DA/NIDA NIH HHS/ -- P01 DA010044-159002/DA/NIDA NIH HHS/ -- P01 DA08227/DA/NIDA NIH HHS/ -- P0110044/PHS HHS/ -- R01 DA007359/DA/NIDA NIH HHS/ -- R01 DA007359-02/DA/NIDA NIH HHS/ -- R01 DA007359-17/DA/NIDA NIH HHS/ -- R01 DA007359-18/DA/NIDA NIH HHS/ -- R01 DA007359-19/DA/NIDA NIH HHS/ -- R01 DA007359-20/DA/NIDA NIH HHS/ -- R01 DA007359-21/DA/NIDA NIH HHS/ -- R01 DA007359-22/DA/NIDA NIH HHS/ -- R01 DA014133/DA/NIDA NIH HHS/ -- R01 DA07359/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):213-6. doi: 10.1126/science.1179438.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fishberg Department of Neuroscience, Mount Sinai School of Medicine, New York, NY, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056891" target="_blank"〉PubMed〈/a〉

    Reefs as cradles of evolution and sources of biodiversity in the Phanerozoic (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-09
    Description: Large-scale biodiversity gradients among environments and habitats are usually attributed to a complex array of ecological and evolutionary factors. We tested the evolutionary component of such gradients by compiling the environments of the geologically oldest occurrences of marine genera and using sampling standardization to assess if originations tended to be clustered in particular environments. Shallow, tropical environments and carbonate substrates all tend to have harbored high origination rates. Diversity within these environments tended to be preferentially generated in reefs, probably because of their habitat complexity. Reefs were also prolific at exporting diversity to other environments, which might be a consequence of low-diversity habitats being more susceptible to invasions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kiessling, Wolfgang -- Simpson, Carl -- Foote, Michael -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):196-8. doi: 10.1126/science.1182241.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museum fur Naturkunde, Leibniz Institute for Research on Evolution and Biodiversity at the Humboldt University Berlin, 10115 Berlin, Germany. wolfgang.kiessling@mfn-berlin.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056888" target="_blank"〉PubMed〈/a〉

    High frequency of horizontal gene transfer in the oceans (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-12
    Description: Oceanic bacteria perform many environmental functions, including biogeochemical cycling of many elements, metabolizing of greenhouse gases, functioning in oceanic food webs (microbial loop), and producing valuable natural products and viruses. We demonstrate that the widespread capability of marine bacteria to participate in horizontal gene transfer (HGT) in coastal and oceanic environments may be the result of gene transfer agents (GTAs), viral-like particles produced by alpha-Proteobacteria. We documented GTA-mediated gene transfer frequencies a thousand to a hundred million times higher than prior estimates of HGT in the oceans, with as high as 47% of the culturable natural microbial community confirmed as gene recipients. These findings suggest a plausible mechanism by which marine bacteria acquire novel traits, thus ensuring resilience in the face of environmental change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDaniel, Lauren D -- Young, Elizabeth -- Delaney, Jennifer -- Ruhnau, Fabian -- Ritchie, Kim B -- Paul, John H -- New York, N.Y. -- Science. 2010 Oct 1;330(6000):50. doi: 10.1126/science.1192243.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of South Florida College of Marine Science, St. Petersburg, FL 33701, USA. mcdaniel@marine.usf.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929803" target="_blank"〉PubMed〈/a〉

    Publication Date: 2010-06-19
    Description: Climate change, rising atmospheric carbon dioxide, excess nutrient inputs, and pollution in its many forms are fundamentally altering the chemistry of the ocean, often on a global scale and, in some cases, at rates greatly exceeding those in the historical and recent geological record. Major observed trends include a shift in the acid-base chemistry of seawater, reduced subsurface oxygen both in near-shore coastal water and in the open ocean, rising coastal nitrogen levels, and widespread increase in mercury and persistent organic pollutants. Most of these perturbations, tied either directly or indirectly to human fossil fuel combustion, fertilizer use, and industrial activity, are projected to grow in coming decades, resulting in increasing negative impacts on ocean biota and marine resources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doney, Scott C -- New York, N.Y. -- Science. 2010 Jun 18;328(5985):1512-6. doi: 10.1126/science.1185198.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Chemistry and Geochemistry Department, Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA. sdoney@whoi.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20558706" target="_blank"〉PubMed〈/a〉

    Induction of lymphoidlike stroma and immune escape by tumors that express the chemokine CCL21 (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-03-27
    Description: Tumor manipulation of host immunity is important for tumor survival and invasion. Many cancers secrete CCL21, a chemoattractant for various leukocytes and lymphoid tissue inducer cells, which drive lymphoid neogenesis. CCL21 expression by melanoma tumors in mice was associated with an immunotolerant microenvironment, which included the induction of lymphoid-like reticular stromal networks, an altered cytokine milieu, and the recruitment of regulatory leukocyte populations. In contrast, CCL21-deficient tumors induced antigen-specific immunity. CCL21-mediated immune tolerance was dependent on host rather than tumor expression of the CCL21 receptor, CCR7, and could protect distant, coimplanted CCL21-deficient tumors and even nonsyngeneic allografts from rejection. We suggest that by altering the tumor microenvironment, CCL21-secreting tumors shift the host immune response from immunogenic to tolerogenic, which facilitates tumor progression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shields, Jacqueline D -- Kourtis, Iraklis C -- Tomei, Alice A -- Roberts, Joanna M -- Swartz, Melody A -- New York, N.Y. -- Science. 2010 May 7;328(5979):749-52. doi: 10.1126/science.1185837.

    A cryptic sulfur cycle in oxygen-minimum-zone waters off the Chilean coast (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-11-13
    Description: Nitrogen cycling is normally thought to dominate the biogeochemistry and microbial ecology of oxygen-minimum zones in marine environments. Through a combination of molecular techniques and process rate measurements, we showed that both sulfate reduction and sulfide oxidation contribute to energy flux and elemental cycling in oxygen-free waters off the coast of northern Chile. These processes may have been overlooked because in nature, the sulfide produced by sulfate reduction immediately oxidizes back to sulfate.

    Ocean warming slows coral growth in the central Red Sea (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-07-22
    Description: Sea surface temperature (SST) across much of the tropics has increased by 0.4 degrees to 1 degrees C since the mid-1970s. A parallel increase in the frequency and extent of coral bleaching and mortality has fueled concern that climate change poses a major threat to the survival of coral reef ecosystems worldwide. Here we show that steadily rising SSTs, not ocean acidification, are already driving dramatic changes in the growth of an important reef-building coral in the central Red Sea. Three-dimensional computed tomography analyses of the massive coral Diploastrea heliopora reveal that skeletal growth of apparently healthy colonies has declined by 30% since 1998. The same corals responded to a short-lived warm event in 1941/1942, but recovered within 3 years as the ocean cooled. Combining our data with climate model simulations by the Intergovernmental Panel on Climate Change, we predict that should the current warming trend continue, this coral could cease growing altogether by 2070.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cantin, Neal E -- Cohen, Anne L -- Karnauskas, Kristopher B -- Tarrant, Ann M -- McCorkle, Daniel C -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):322-5. doi: 10.1126/science.1190182.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20647466" target="_blank"〉PubMed〈/a〉

    A critical role for LTA4H in limiting chronic pulmonary neutrophilic inflammation (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-09-04
    Description: Leukotriene A(4) hydrolase (LTA(4)H) is a proinflammatory enzyme that generates the inflammatory mediator leukotriene B(4) (LTB(4)). LTA(4)H also possesses aminopeptidase activity with unknown substrate and physiological importance; we identified the neutrophil chemoattractant proline-glycine-proline (PGP) as this physiological substrate. PGP is a biomarker for chronic obstructive pulmonary disease (COPD) and is implicated in neutrophil persistence in the lung. In acute neutrophil-driven inflammation, PGP was degraded by LTA(4)H, which facilitated the resolution of inflammation. In contrast, cigarette smoke, a major risk factor for the development of COPD, selectively inhibited LTA(4)H aminopeptidase activity, which led to the accumulation of PGP and neutrophils. These studies imply that therapeutic strategies inhibiting LTA(4)H to prevent LTB(4) generation may not reduce neutrophil recruitment because of elevated levels of PGP.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3072752/" 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/PMC3072752/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Snelgrove, Robert J -- Jackson, Patricia L -- Hardison, Matthew T -- Noerager, Brett D -- Kinloch, Andrew -- Gaggar, Amit -- Shastry, Suresh -- Rowe, Steven M -- Shim, Yun M -- Hussell, Tracy -- Blalock, J Edwin -- 082727/Z/07/Z/Wellcome Trust/United Kingdom -- 1K23DK075788/DK/NIDDK NIH HHS/ -- 1R03DK084110-01/DK/NIDDK NIH HHS/ -- G0400795/Medical Research Council/United Kingdom -- G0802752/Medical Research Council/United Kingdom -- HL07783/HL/NHLBI NIH HHS/ -- HL087824/HL/NHLBI NIH HHS/ -- HL090999/HL/NHLBI NIH HHS/ -- HL102371-A1/HL/NHLBI NIH HHS/ -- K08HL091127/HL/NHLBI NIH HHS/ -- P171/03/C1/048/Medical Research Council/United Kingdom -- P30 DK079337/DK/NIDDK NIH HHS/ -- P30AR050948/AR/NIAMS NIH HHS/ -- P30CA13148/CA/NCI NIH HHS/ -- P50 AT00477/AT/NCCIH NIH HHS/ -- R01 HL077783/HL/NHLBI NIH HHS/ -- R01 HL077783-05/HL/NHLBI NIH HHS/ -- R01 HL087824/HL/NHLBI NIH HHS/ -- R01 HL087824-02/HL/NHLBI NIH HHS/ -- R01 HL090999/HL/NHLBI NIH HHS/ -- R01 HL090999-02S1/HL/NHLBI NIH HHS/ -- R01 HL090999-04/HL/NHLBI NIH HHS/ -- R01 HL102371/HL/NHLBI NIH HHS/ -- RR19231/RR/NCRR NIH HHS/ -- U54CA100949/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 1;330(6000):90-4. doi: 10.1126/science.1190594.

    Scenarios for global biodiversity in the 21st century (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-28
    Description: Quantitative scenarios are coming of age as a tool for evaluating the impact of future socioeconomic development pathways on biodiversity and ecosystem services. We analyze global terrestrial, freshwater, and marine biodiversity scenarios using a range of measures including extinctions, changes in species abundance, habitat loss, and distribution shifts, as well as comparing model projections to observations. Scenarios consistently indicate that biodiversity will continue to decline over the 21st century. However, the range of projected changes is much broader than most studies suggest, partly because there are major opportunities to intervene through better policies, but also because of large uncertainties in projections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pereira, Henrique M -- Leadley, Paul W -- Proenca, Vania -- Alkemade, Rob -- Scharlemann, Jorn P W -- Fernandez-Manjarres, Juan F -- Araujo, Miguel B -- Balvanera, Patricia -- Biggs, Reinette -- Cheung, William W L -- Chini, Louise -- Cooper, H David -- Gilman, Eric L -- Guenette, Sylvie -- Hurtt, George C -- Huntington, Henry P -- Mace, Georgina M -- Oberdorff, Thierry -- Revenga, Carmen -- Rodrigues, Patricia -- Scholes, Robert J -- Sumaila, Ussif Rashid -- Walpole, Matt -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1496-501. doi: 10.1126/science.1196624.

    The Wnt/beta-catenin pathway is required for the development of leukemia stem cells in AML (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-03-27
    Description: Leukemia stem cells (LSCs) are capable of limitless self-renewal and are responsible for the maintenance of leukemia. Because selective eradication of LSCs could offer substantial therapeutic benefit, there is interest in identifying the signaling pathways that control their development. We studied LSCs in mouse models of acute myelogenous leukemia (AML) induced either by coexpression of the Hoxa9 and Meis1a oncogenes or by the fusion oncoprotein MLL-AF9. We show that the Wnt/beta-catenin signaling pathway is required for self-renewal of LSCs that are derived from either hematopoietic stem cells (HSC) or more differentiated granulocyte-macrophage progenitors (GMP). Because the Wnt/beta-catenin pathway is normally active in HSCs but not in GMP, these results suggest that reactivation of beta-catenin signaling is required for the transformation of progenitor cells by certain oncogenes. beta-catenin is not absolutely required for self-renewal of adult HSCs; thus, targeting the Wnt/beta-catenin pathway may represent a new therapeutic opportunity in AML.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3084586/" 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/PMC3084586/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Yingzi -- Krivtsov, Andrei V -- Sinha, Amit U -- North, Trista E -- Goessling, Wolfram -- Feng, Zhaohui -- Zon, Leonard I -- Armstrong, Scott A -- 5P01CA66996/CA/NCI NIH HHS/ -- 5R01HL048801/HL/NHLBI NIH HHS/ -- P01 CA066996/CA/NCI NIH HHS/ -- P01 CA066996-11A1/CA/NCI NIH HHS/ -- R01 HL048801/HL/NHLBI NIH HHS/ -- R01 HL048801-16/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1650-3. doi: 10.1126/science.1186624.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology/Oncology, Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20339075" target="_blank"〉PubMed〈/a〉

    Cortical plasticity induced by inhibitory neuron transplantation (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-02-27
    Description: Critical periods are times of pronounced brain plasticity. During a critical period in the postnatal development of the visual cortex, the occlusion of one eye triggers a rapid reorganization of neuronal responses, a process known as ocular dominance plasticity. We have shown that the transplantation of inhibitory neurons induces ocular dominance plasticity after the critical period. Transplanted inhibitory neurons receive excitatory synapses, make inhibitory synapses onto host cortical neurons, and promote plasticity when they reach a cellular age equivalent to that of endogenous inhibitory neurons during the normal critical period. These findings suggest that ocular dominance plasticity is regulated by the execution of a maturational program intrinsic to inhibitory neurons. By inducing plasticity, inhibitory neuron transplantation may facilitate brain repair.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164148/" 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/PMC3164148/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Southwell, Derek G -- Froemke, Robert C -- Alvarez-Buylla, Arturo -- Stryker, Michael P -- Gandhi, Sunil P -- EY016317/EY/NEI NIH HHS/ -- F32 EY016317/EY/NEI NIH HHS/ -- F32 EY016317-03/EY/NEI NIH HHS/ -- P50 MH077972/MH/NIMH NIH HHS/ -- P50 MH077972-05/MH/NIMH NIH HHS/ -- R01 NS048528/NS/NINDS NIH HHS/ -- R01 NS048528-04/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 26;327(5969):1145-8. doi: 10.1126/science.1183962.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurological Surgery and the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research, University of California, San Francisco, 513 Parnassus Avenue, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20185728" target="_blank"〉PubMed〈/a〉

    Hippocampal short- and long-term plasticity are not modulated by astrocyte Ca2+ signaling (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-03-06
    Description: The concept that astrocytes release neuroactive molecules (gliotransmitters) to affect synaptic transmission has been a paradigm shift in neuroscience research over the past decade. This concept suggests that astrocytes, together with pre- and postsynaptic neuronal elements, make up a functional synapse. Astrocyte release of gliotransmitters (for example, glutamate and adenosine triphosphate) is generally accepted to be a Ca2+-dependent process. We used two mouse lines to either selectively increase or obliterate astrocytic Gq G protein-coupled receptor Ca2+ signaling to further test the hypothesis that astrocytes release gliotransmitters in a Ca2+-dependent manner to affect synaptic transmission. Neither increasing nor obliterating astrocytic Ca2+ fluxes affects spontaneous and evoked excitatory synaptic transmission or synaptic plasticity. Our findings suggest that, at least in the hippocampus, the mechanisms of gliotransmission need to be reconsidered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Agulhon, Cendra -- Fiacco, Todd A -- McCarthy, Ken D -- NS020212/NS/NINDS NIH HHS/ -- NS033938/NS/NINDS NIH HHS/ -- R01 NS020212/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2010 Mar 5;327(5970):1250-4. doi: 10.1126/science.1184821.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of North Carolina at Chapel Hill, Genetic Medicine Building, CB 7365, Chapel Hill, NC 27599, USA. cendra_agulhon@med.unc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20203048" target="_blank"〉PubMed〈/a〉

(Reports, 19 March 2010, p. 1509) argued that stable conditions enable neutral coexistence of many phytoplankton species in the tropical oceans, whereas seasonal variation causes low biodiversity in subpolar oceans. However, their model prediction is not robust. A minor deviation from the neutrality assumption favors coexistence in fluctuating rather than stable environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huisman, Jef -- New York, N.Y. -- Science. 2010 Jul 30;329(5991):512; author reply 512. doi: 10.1126/science.1189880.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Aquatic Microbiology, Institute for Biodiversity and Ecosystem Dynamics, University of Amsterdam, Post Office Box 94248, 1090 GE Amsterdam, Netherlands. j.huisman@uva.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20671171" target="_blank"〉PubMed〈/a〉

    O-mannosyl phosphorylation of alpha-dystroglycan is required for laminin binding (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-02
    Description: Alpha-dystroglycan (alpha-DG) is a cell-surface glycoprotein that acts as a receptor for both extracellular matrix proteins containing laminin-G domains and certain arenaviruses. Receptor binding is thought to be mediated by a posttranslational modification, and defective binding with laminin underlies a subclass of congenital muscular dystrophy. Using mass spectrometry- and nuclear magnetic resonance (NMR)-based structural analyses, we identified a phosphorylated O-mannosyl glycan on the mucin-like domain of recombinant alpha-DG, which was required for laminin binding. We demonstrated that patients with muscle-eye-brain disease and Fukuyama congenital muscular dystrophy, as well as mice with myodystrophy, commonly have defects in a postphosphoryl modification of this phosphorylated O-linked mannose, and that this modification is mediated by the like-acetylglucosaminyltransferase (LARGE) protein. These findings expand our understanding of the mechanisms that underlie congenital muscular dystrophy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2978000/" 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/PMC2978000/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida-Moriguchi, Takako -- Yu, Liping -- Stalnaker, Stephanie H -- Davis, Sarah -- Kunz, Stefan -- Madson, Michael -- Oldstone, Michael B A -- Schachter, Harry -- Wells, Lance -- Campbell, Kevin P -- 1U54NS053672/NS/NINDS NIH HHS/ -- AI55540/AI/NIAID NIH HHS/ -- P30 DK 54759/DK/NIDDK NIH HHS/ -- P30 DK054759/DK/NIDDK NIH HHS/ -- P41 RR018502/RR/NCRR NIH HHS/ -- R01 AI009484/AI/NIAID NIH HHS/ -- R01 AI009484-40/AI/NIAID NIH HHS/ -- R01 AI009484-41/AI/NIAID NIH HHS/ -- R01 AI045927/AI/NIAID NIH HHS/ -- R01 AI045927-08/AI/NIAID NIH HHS/ -- R01 AI045927-09/AI/NIAID NIH HHS/ -- R01 AI045927-10/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jan 1;327(5961):88-92. doi: 10.1126/science.1180512.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Iowa Roy J. and Lucille A.

    Lynx1, a cholinergic brake, limits plasticity in adult visual cortex (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-11-13
    Description: Experience-dependent brain plasticity typically declines after an early critical period during which circuits are established. Loss of plasticity with closure of the critical period limits improvement of function in adulthood, but the mechanisms that change the brain's plasticity remain poorly understood. Here, we identified an increase in expression of Lynx1 protein in mice that prevented plasticity in the primary visual cortex late in life. Removal of this molecular brake enhanced nicotinic acetylcholine receptor signaling. Lynx1 expression thus maintains stability of mature cortical networks in the presence of cholinergic innervation. The results suggest that modulating the balance between excitatory and inhibitory circuits reactivates visual plasticity and may present a therapeutic target.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3387538/" 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/PMC3387538/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morishita, Hirofumi -- Miwa, Julie M -- Heintz, Nathaniel -- Hensch, Takao K -- 1 DP1 OD003699-01/OD/NIH HHS/ -- DA-17279/DA/NIDA NIH HHS/ -- DP1 OD003699/OD/NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Nov 26;330(6008):1238-40. doi: 10.1126/science.1195320.

    Trophic downgrading of planet Earth (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-19
    Description: Until recently, large apex consumers were ubiquitous across the globe and had been for millions of years. The loss of these animals may be humankind's most pervasive influence on nature. Although such losses are widely viewed as an ethical and aesthetic problem, recent research reveals extensive cascading effects of their disappearance in marine, terrestrial, and freshwater ecosystems worldwide. This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles. These findings emphasize the urgent need for interdisciplinary research to forecast the effects of trophic downgrading on process, function, and resilience in global ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Estes, James A -- Terborgh, John -- Brashares, Justin S -- Power, Mary E -- Berger, Joel -- Bond, William J -- Carpenter, Stephen R -- Essington, Timothy E -- Holt, Robert D -- Jackson, Jeremy B C -- Marquis, Robert J -- Oksanen, Lauri -- Oksanen, Tarja -- Paine, Robert T -- Pikitch, Ellen K -- Ripple, William J -- Sandin, Stuart A -- Scheffer, Marten -- Schoener, Thomas W -- Shurin, Jonathan B -- Sinclair, Anthony R E -- Soule, Michael E -- Virtanen, Risto -- Wardle, David A -- New York, N.Y. -- Science. 2011 Jul 15;333(6040):301-6. doi: 10.1126/science.1205106.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95060, USA. jestes@ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21764740" target="_blank"〉PubMed〈/a〉

    The pace of shifting climate in marine and terrestrial ecosystems (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-11-05
    Description: Climate change challenges organisms to adapt or move to track changes in environments in space and time. We used two measures of thermal shifts from analyses of global temperatures over the past 50 years to describe the pace of climate change that species should track: the velocity of climate change (geographic shifts of isotherms over time) and the shift in seasonal timing of temperatures. Both measures are higher in the ocean than on land at some latitudes, despite slower ocean warming. These indices give a complex mosaic of predicted range shifts and phenology changes that deviate from simple poleward migration and earlier springs or later falls. They also emphasize potential conservation concerns, because areas of high marine biodiversity often have greater velocities of climate change and seasonal shifts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burrows, Michael T -- Schoeman, David S -- Buckley, Lauren B -- Moore, Pippa -- Poloczanska, Elvira S -- Brander, Keith M -- Brown, Chris -- Bruno, John F -- Duarte, Carlos M -- Halpern, Benjamin S -- Holding, Johnna -- Kappel, Carrie V -- Kiessling, Wolfgang -- O'Connor, Mary I -- Pandolfi, John M -- Parmesan, Camille -- Schwing, Franklin B -- Sydeman, William J -- Richardson, Anthony J -- New York, N.Y. -- Science. 2011 Nov 4;334(6056):652-5. doi: 10.1126/science.1210288.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Scottish Association for Marine Science, Scottish Marine Institute, Oban, Argyll, PA37 1QA, Scotland, UK. michael.burrows@sams.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22053045" target="_blank"〉PubMed〈/a〉

    Predicting a human gut microbiota's response to diet in gnotobiotic mice (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-05-21
    Description: The interrelationships between our diets and the structure and operations of our gut microbial communities are poorly understood. A model community of 10 sequenced human gut bacteria was introduced into gnotobiotic mice, and changes in species abundance and microbial gene expression were measured in response to randomized perturbations of four defined ingredients in the host diet. From the responses, we developed a statistical model that predicted over 60% of the variation in species abundance evoked by diet perturbations, and we were able to identify which factors in the diet best explained changes seen for each community member. The approach is generally applicable, as shown by a follow-up study involving diets containing various mixtures of pureed human baby foods.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303606/" 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/PMC3303606/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faith, Jeremiah J -- McNulty, Nathan P -- Rey, Federico E -- Gordon, Jeffrey I -- DK30292/DK/NIDDK NIH HHS/ -- DK70977/DK/NIDDK NIH HHS/ -- R01 DK070977/DK/NIDDK NIH HHS/ -- R01 DK070977-08/DK/NIDDK NIH HHS/ -- R37 DK030292/DK/NIDDK NIH HHS/ -- R37 DK030292-31/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):101-4. doi: 10.1126/science.1206025.

    Cerebellum shapes hippocampal spatial code (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-10-25
    Description: Spatial representation is an active process that requires complex multimodal integration from a large interacting network of cortical and subcortical structures. We sought to determine the role of cerebellar protein kinase C (PKC)-dependent plasticity in spatial navigation by recording the activity of hippocampal place cells in transgenic L7PKCI mice with selective disruption of PKC-dependent plasticity at parallel fiber-Purkinje cell synapses. Place cell properties were exclusively impaired when L7PKCI mice had to rely on self-motion cues. The behavioral consequence of such a deficit is evidenced here by selectively impaired navigation capabilities during a path integration task. Together, these results suggest that cerebellar PKC-dependent mechanisms are involved in processing self-motion signals essential to the shaping of hippocampal spatial representation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rochefort, Christelle -- Arabo, Arnaud -- Andre, Marion -- Poucet, Bruno -- Save, Etienne -- Rondi-Reig, Laure -- New York, N.Y. -- Science. 2011 Oct 21;334(6054):385-9. doi: 10.1126/science.1207403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurobiologie des Processus Adaptatifs (UMR 7102), Navigation, Memory, and Aging (ENMVI) Team, Universite Pierre et Marie Curie-Centre National de la Recherche Scientifique (CNRS), F-75005 Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22021859" target="_blank"〉PubMed〈/a〉

    A circadian rhythm orchestrated by histone deacetylase 3 controls hepatic lipid metabolism (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-03-12
    Description: Disruption of the circadian clock exacerbates metabolic diseases, including obesity and diabetes. We show that histone deacetylase 3 (HDAC3) recruitment to the genome displays a circadian rhythm in mouse liver. Histone acetylation is inversely related to HDAC3 binding, and this rhythm is lost when HDAC3 is absent. Although amounts of HDAC3 are constant, its genomic recruitment in liver corresponds to the expression pattern of the circadian nuclear receptor Rev-erbalpha. Rev-erbalpha colocalizes with HDAC3 near genes regulating lipid metabolism, and deletion of HDAC3 or Rev-erbalpha in mouse liver causes hepatic steatosis. Thus, genomic recruitment of HDAC3 by Rev-erbalpha directs a circadian rhythm of histone acetylation and gene expression required for normal hepatic lipid homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3389392/" 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/PMC3389392/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, Dan -- Liu, Tao -- Sun, Zheng -- Bugge, Anne -- Mullican, Shannon E -- Alenghat, Theresa -- Liu, X Shirley -- Lazar, Mitchell A -- DK19525/DK/NIDDK NIH HHS/ -- DK43806/DK/NIDDK NIH HHS/ -- DK45586/DK/NIDDK NIH HHS/ -- DK49210/DK/NIDDK NIH HHS/ -- HG4069/HG/NHGRI NIH HHS/ -- P30 DK019525/DK/NIDDK NIH HHS/ -- R01 DK045586/DK/NIDDK NIH HHS/ -- R37 DK043806/DK/NIDDK NIH HHS/ -- R37 DK043806-20/DK/NIDDK NIH HHS/ -- RC1 DK086239/DK/NIDDK NIH HHS/ -- RC1DK08623/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2011 Mar 11;331(6022):1315-9. doi: 10.1126/science.1198125.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Endocrinology, Diabetes, and Metabolism, Department of Medicine, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21393543" target="_blank"〉PubMed〈/a〉

    Leishmania RNA virus controls the severity of mucocutaneous leishmaniasis (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-02-12
    Description: Mucocutaneous leishmaniasis is caused by infections with intracellular parasites of the Leishmania Viannia subgenus, including Leishmania guyanensis. The pathology develops after parasite dissemination to nasopharyngeal tissues, where destructive metastatic lesions form with chronic inflammation. Currently, the mechanisms involved in lesion development are poorly understood. Here we show that metastasizing parasites have a high Leishmania RNA virus-1 (LRV1) burden that is recognized by the host Toll-like receptor 3 (TLR3) to induce proinflammatory cytokines and chemokines. Paradoxically, these TLR3-mediated immune responses rendered mice more susceptible to infection, and the animals developed an increased footpad swelling and parasitemia. Thus, LRV1 in the metastasizing parasites subverted the host immune response to Leishmania and promoted parasite persistence.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3253482/" 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/PMC3253482/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ives, Annette -- Ronet, Catherine -- Prevel, Florence -- Ruzzante, Giulia -- Fuertes-Marraco, Silvia -- Schutz, Frederic -- Zangger, Haroun -- Revaz-Breton, Melanie -- Lye, Lon-Fye -- Hickerson, Suzanne M -- Beverley, Stephen M -- Acha-Orbea, Hans -- Launois, Pascal -- Fasel, Nicolas -- Masina, Slavica -- A129646/PHS HHS/ -- R01 AI029646/AI/NIAID NIH HHS/ -- R01 AI029646-23/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2011 Feb 11;331(6018):775-8. doi: 10.1126/science.1199326.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Lausanne, 1066 Epalinges, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21311023" target="_blank"〉PubMed〈/a〉

    A gustotopic map of taste qualities in the mammalian brain (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-09-03
    Description: The taste system is one of our fundamental senses, responsible for detecting and responding to sweet, bitter, umami, salty, and sour stimuli. In the tongue, the five basic tastes are mediated by separate classes of taste receptor cells each finely tuned to a single taste quality. We explored the logic of taste coding in the brain by examining how sweet, bitter, umami, and salty qualities are represented in the primary taste cortex of mice. We used in vivo two-photon calcium imaging to demonstrate topographic segregation in the functional architecture of the gustatory cortex. Each taste quality is represented in its own separate cortical field, revealing the existence of a gustotopic map in the brain. These results expose the basic logic for the central representation of taste.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3523322/" 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/PMC3523322/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Xiaoke -- Gabitto, Mariano -- Peng, Yueqing -- Ryba, Nicholas J P -- Zuker, Charles S -- Z01 DE000561-15/Intramural NIH HHS/ -- Z01 DE000561-16/Intramural NIH HHS/ -- ZIA DE000561-17/Intramural NIH HHS/ -- ZIA DE000561-18/Intramural NIH HHS/ -- ZIA DE000561-19/Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Sep 2;333(6047):1262-6. doi: 10.1126/science.1204076.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biochemistry and Molecular Biophysics, College of Physicians and Surgeons, Columbia University, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21885776" target="_blank"〉PubMed〈/a〉

    Archaeorhizomycetes: unearthing an ancient class of ubiquitous soil fungi (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-08-13
    Description: Estimates suggest that only one-tenth of the true fungal diversity has been described. Among numerous fungal lineages known only from environmental DNA sequences, Soil Clone Group 1 is the most ubiquitous. These globally distributed fungi may dominate below-ground fungal communities, but their placement in the fungal tree of life has been uncertain. Here, we report cultures of this group and describe the class, Archaeorhizomycetes, phylogenetically placed within subphylum Taphrinomycotina in the Ascomycota. Archaeorhizomycetes comprises hundreds of cryptically reproducing filamentous species that do not form recognizable mycorrhizal structures and have saprotrophic potential, yet are omnipresent in roots and rhizosphere soil and show ecosystem and host root habitat specificity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosling, Anna -- Cox, Filipa -- Cruz-Martinez, Karelyn -- Ihrmark, Katarina -- Grelet, Gwen-Aelle -- Lindahl, Bjorn D -- Menkis, Audrius -- James, Timothy Y -- New York, N.Y. -- Science. 2011 Aug 12;333(6044):876-9. doi: 10.1126/science.1206958.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Forest Mycology and Pathology, Uppsala BioCentre, SLU, Box 7026, 750 07 Uppsala, Sweden. anna.rosling@slu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21836015" target="_blank"〉PubMed〈/a〉

    Early warnings of regime shifts: a whole-ecosystem experiment (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-04-30
    Description: Catastrophic ecological regime shifts may be announced in advance by statistical early warning signals such as slowing return rates from perturbation and rising variance. The theoretical background for these indicators is rich, but real-world tests are rare, especially for whole ecosystems. We tested the hypothesis that these statistics would be early warning signals for an experimentally induced regime shift in an aquatic food web. We gradually added top predators to a lake over 3 years to destabilize its food web. An adjacent lake was monitored simultaneously as a reference ecosystem. Warning signals of a regime shift were evident in the manipulated lake during reorganization of the food web more than a year before the food web transition was complete, corroborating theory for leading indicators of ecological regime shifts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carpenter, S R -- Cole, J J -- Pace, M L -- Batt, R -- Brock, W A -- Cline, T -- Coloso, J -- Hodgson, J R -- Kitchell, J F -- Seekell, D A -- Smith, L -- Weidel, B -- New York, N.Y. -- Science. 2011 May 27;332(6033):1079-82. doi: 10.1126/science.1203672.

    The Toll-like receptor 2 pathway establishes colonization by a commensal of the human microbiota (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-04-23
    Description: Mucosal surfaces constantly encounter microbes. Toll-like receptors (TLRs) mediate recognition of microbial patterns to eliminate pathogens. By contrast, we demonstrate that the prominent gut commensal Bacteroides fragilis activates the TLR pathway to establish host-microbial symbiosis. TLR2 on CD4(+) T cells is required for B. fragilis colonization of a unique mucosal niche in mice during homeostasis. A symbiosis factor (PSA, polysaccharide A) of B. fragilis signals through TLR2 directly on Foxp3(+) regulatory T cells to promote immunologic tolerance. B. fragilis lacking PSA is unable to restrain T helper 17 cell responses and is defective in niche-specific mucosal colonization. Therefore, commensal bacteria exploit the TLR pathway to actively suppress immunity. We propose that the immune system can discriminate between pathogens and the microbiota through recognition of symbiotic bacterial molecules in a process that engenders commensal colonization.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164325/" 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/PMC3164325/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Round, June L -- Lee, S Melanie -- Li, Jennifer -- Tran, Gloria -- Jabri, Bana -- Chatila, Talal A -- Mazmanian, Sarkis K -- AI 080002/AI/NIAID NIH HHS/ -- AI 088626/AI/NIAID NIH HHS/ -- DK 078938/DK/NIDDK NIH HHS/ -- DK 083633/DK/NIDDK NIH HHS/ -- R01 AI085090/AI/NIAID NIH HHS/ -- R01 AI085090-01/AI/NIAID NIH HHS/ -- R01 AI085090-01S1/AI/NIAID NIH HHS/ -- R01 AI085090-02/AI/NIAID NIH HHS/ -- R01 AI085090-03/AI/NIAID NIH HHS/ -- R01 DK078938/DK/NIDDK NIH HHS/ -- R01 DK078938-01A2/DK/NIDDK NIH HHS/ -- R01 DK078938-02/DK/NIDDK NIH HHS/ -- R01 DK078938-03/DK/NIDDK NIH HHS/ -- R01 DK078938-04/DK/NIDDK NIH HHS/ -- R21 AI080002/AI/NIAID NIH HHS/ -- R21 AI080002-01/AI/NIAID NIH HHS/ -- R21 AI080002-02/AI/NIAID NIH HHS/ -- R21 AI088626/AI/NIAID NIH HHS/ -- R21 AI088626-01/AI/NIAID NIH HHS/ -- R21 AI088626-02/AI/NIAID NIH HHS/ -- R21 DK083633/DK/NIDDK NIH HHS/ -- R21 DK083633-01A1/DK/NIDDK NIH HHS/ -- R21 DK083633-02/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):974-7. doi: 10.1126/science.1206095.

    Endocannabinoid hydrolysis generates brain prostaglandins that promote neuroinflammation (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-10-25
    Description: Phospholipase A(2)(PLA(2)) enzymes are considered the primary source of arachidonic acid for cyclooxygenase (COX)-mediated biosynthesis of prostaglandins. Here, we show that a distinct pathway exists in brain, where monoacylglycerol lipase (MAGL) hydrolyzes the endocannabinoid 2-arachidonoylglycerol to generate a major arachidonate precursor pool for neuroinflammatory prostaglandins. MAGL-disrupted animals show neuroprotection in a parkinsonian mouse model. These animals are spared the hemorrhaging caused by COX inhibitors in the gut, where prostaglandins are instead regulated by cytosolic PLA(2). These findings identify MAGL as a distinct metabolic node that couples endocannabinoid to prostaglandin signaling networks in the nervous system and suggest that inhibition of this enzyme may be a new and potentially safer way to suppress the proinflammatory cascades that underlie neurodegenerative disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3249428/" 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/PMC3249428/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nomura, Daniel K -- Morrison, Bradley E -- Blankman, Jacqueline L -- Long, Jonathan Z -- Kinsey, Steven G -- Marcondes, Maria Cecilia G -- Ward, Anna M -- Hahn, Yun Kyung -- Lichtman, Aron H -- Conti, Bruno -- Cravatt, Benjamin F -- 5P01DA009789/DA/NIDA NIH HHS/ -- AG028040/AG/NIA NIH HHS/ -- DA017259/DA/NIDA NIH HHS/ -- DA026261/DA/NIDA NIH HHS/ -- F31 DA026261-03/DA/NIDA NIH HHS/ -- K99 DA030908/DA/NIDA NIH HHS/ -- K99 DA030908-01/DA/NIDA NIH HHS/ -- K99DA030908/DA/NIDA NIH HHS/ -- P01 DA009789/DA/NIDA NIH HHS/ -- P01 DA009789-14/DA/NIDA NIH HHS/ -- P01 DA017259/DA/NIDA NIH HHS/ -- P01 DA017259-08/DA/NIDA NIH HHS/ -- P01DA01725/DA/NIDA NIH HHS/ -- R00 DA030908/DA/NIDA NIH HHS/ -- R00 DA030908-02/DA/NIDA NIH HHS/ -- R00DA030908/DA/NIDA NIH HHS/ -- R01 AG028040/AG/NIA NIH HHS/ -- R01 AG028040-04/AG/NIA NIH HHS/ -- R03 DA027936/DA/NIDA NIH HHS/ -- R03 DA027936-02/DA/NIDA NIH HHS/ -- R03DA027936/DA/NIDA NIH HHS/ -- T32 DA007027/DA/NIDA NIH HHS/ -- T32 DA007027-33/DA/NIDA NIH HHS/ -- T32DA007027/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2011 Nov 11;334(6057):809-13. doi: 10.1126/science.1209200.

    Description: Zhao and Running (Reports, 20 August 2010, p. 940) reported a reduction in global terrestrial net primary production (NPP) from 2000 through 2009. We argue that the small trends, regional patterns, and interannual variations that they describe are artifacts of their NPP model. Satellite observations of vegetation activity show no statistically significant changes in more than 85% of the vegetated lands south of 70 degrees N during the same 2000 to 2009 period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Samanta, Arindam -- Costa, Marcos H -- Nunes, Edson L -- Vieira, Simone A -- Xu, Liang -- Myneni, Ranga B -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1093; author reply 1093. doi: 10.1126/science.1199048.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography and Environment, Boston University, Boston, MA 02215, USA. arindam.sam@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21868655" target="_blank"〉PubMed〈/a〉

    Projecting coral reef futures under global warming and ocean acidification (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-23
    Description: Many physiological responses in present-day coral reefs to climate change are interpreted as consistent with the imminent disappearance of modern reefs globally because of annual mass bleaching events, carbonate dissolution, and insufficient time for substantial evolutionary responses. Emerging evidence for variability in the coral calcification response to acidification, geographical variation in bleaching susceptibility and recovery, responses to past climate change, and potential rates of adaptation to rapid warming supports an alternative scenario in which reef degradation occurs with greater temporal and spatial heterogeneity than current projections suggest. Reducing uncertainty in projecting coral reef futures requires improved understanding of past responses to rapid climate change; physiological responses to interacting factors, such as temperature, acidification, and nutrients; and the costs and constraints imposed by acclimation and adaptation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pandolfi, John M -- Connolly, Sean R -- Marshall, Dustin J -- Cohen, Anne L -- New York, N.Y. -- Science. 2011 Jul 22;333(6041):418-22. doi: 10.1126/science.1204794.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Research Council (ARC) Centre of Excellence for Coral Reef Studies, St. Lucia, Queensland 4072, Australia. j.pandolfi@uq.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21778392" target="_blank"〉PubMed〈/a〉

    Description: Memory B cells formed in response to microbial antigens provide immunity to later infections; however, the inability to detect rare endogenous antigen-specific cells limits current understanding of this process. Using an antigen-based technique to enrich these cells, we found that immunization with a model protein generated B memory cells that expressed isotype-switched immunoglobulins (swIg) or retained IgM. The more numerous IgM(+) cells were longer lived than the swIg(+) cells. However, swIg(+) memory cells dominated the secondary response because of the capacity to become activated in the presence of neutralizing serum immunoglobulin. Thus, we propose that memory relies on swIg(+) cells until they disappear and serum immunoglobulin falls to a low level, in which case memory resides with durable IgM(+) reserves.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3993090/" 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/PMC3993090/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pape, Kathryn A -- Taylor, Justin J -- Maul, Robert W -- Gearhart, Patricia J -- Jenkins, Marc K -- F32 AI091033/AI/NIAID NIH HHS/ -- R01 AI036914/AI/NIAID NIH HHS/ -- R01 AI039614/AI/NIAID NIH HHS/ -- R37 AI027998/AI/NIAID NIH HHS/ -- T32 CA009138/CA/NCI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2011 Mar 4;331(6021):1203-7. doi: 10.1126/science.1201730.

    Cascading effects of bird functional extinction reduce pollination and plant density (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-02-05
    Description: Reductions in bird numbers could hamper ecosystem services such as pollination, but experimental proof is lacking. We show that functional extinction of bird pollinators has reduced pollination, seed production, and plant density in the shrub Rhabdothamnus solandri (Gesneriaceae) on the North Island ("mainland") of New Zealand but not on three nearby island bird sanctuaries where birds remain abundant. Pollen limitation of fruit set is strong [pollen limitation index (PLI) = 0.69] and significant on the mainland but small (PLI = 0.15) and nonsignificant on islands. Seed production per flower on the mainland is reduced 84%. Mainland sites have similar adult densities, but 55% fewer juvenile plants per adult, than island sites. Seed addition experiments near adult R. solandri plants on the mainland found strong seed limitation 5 years after sowing for R. solandri but not for two other co-occurring woody species. This demonstrates a terrestrial trophic cascade.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Sandra H -- Kelly, Dave -- Ladley, Jenny J -- Molloy, Sue -- Terry, Jon -- New York, N.Y. -- Science. 2011 Feb 25;331(6020):1068-71. doi: 10.1126/science.1199092.

    Exercise and genetic rescue of SCA1 via the transcriptional repressor Capicua (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-11-05
    Description: Spinocerebellar ataxia type 1 (SCA1) is a fatal neurodegenerative disease caused by expansion of a translated CAG repeat in Ataxin-1 (ATXN1). To determine the long-term effects of exercise, we implemented a mild exercise regimen in a mouse model of SCA1 and found a considerable improvement in survival accompanied by up-regulation of epidermal growth factor and consequential down-regulation of Capicua, which is an ATXN1 interactor. Offspring of Capicua mutant mice bred to SCA1 mice showed significant improvement of all disease phenotypes. Although polyglutamine-expanded Atxn1 caused some loss of Capicua function, further reduction of Capicua levels--either genetically or by exercise--mitigated the disease phenotypes by dampening the toxic gain of function. Thus, exercise might have long-term beneficial effects in other ataxias and neurodegenerative diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3232424/" 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/PMC3232424/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fryer, John D -- Yu, Peng -- Kang, Hyojin -- Mandel-Brehm, Caleigh -- Carter, Angela N -- Crespo-Barreto, Juan -- Gao, Yan -- Flora, Adriano -- Shaw, Chad -- Orr, Harry T -- Zoghbi, Huda Y -- 1F32NS055545/NS/NINDS NIH HHS/ -- HD24064/HD/NICHD NIH HHS/ -- NS022920/NS/NINDS NIH HHS/ -- NS045667/NS/NINDS NIH HHS/ -- NS27699/NS/NINDS NIH HHS/ -- NS27699-20S1/NS/NINDS NIH HHS/ -- P30 HD024064/HD/NICHD NIH HHS/ -- P30 HD024064-22/HD/NICHD NIH HHS/ -- P30 HD024064-23/HD/NICHD NIH HHS/ -- R01 NS027699/NS/NINDS NIH HHS/ -- R01 NS027699-20S1/NS/NINDS NIH HHS/ -- R01 NS027699-21/NS/NINDS NIH HHS/ -- R01 NS027699-22/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Nov 4;334(6056):690-3. doi: 10.1126/science.1212673.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Human Genetics, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22053053" target="_blank"〉PubMed〈/a〉
