    Nitric oxide activation of poly(ADP-ribose) synthetase in neurotoxicity (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: Poly(adenosine 5'-diphosphoribose) synthetase (PARS) is a nuclear enzyme which, when activated by DNA strand breaks, adds up to 100 adenosine 5'-diphosphoribose (ADP-ribose) units to nuclear proteins such as histones and PARS itself. This activation can lead to cell death through depletion of beta-nicotinamide adenine dinucleotide (the source of ADP-ribose) and adenosine triphosphate. Nitric oxide (NO) stimulated ADP-ribosylation of PARS in rat brain. Benzamide and other derivatives, which inhibit PARS, blocked N-methyl-D-aspartate- and NO-mediated neurotoxicity with relative potencies paralleling their ability to inhibit PARS. Thus, NO appeared to elicit neurotoxicity by activating PARS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, J -- Dawson, V L -- Dawson, T M -- Snyder, S H -- DA-00074/DA/NIDA NIH HHS/ -- DA-00266/DA/NIDA NIH HHS/ -- DA-271-90-7408/DA/NIDA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):687-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8080500" target="_blank"〉PubMed〈/a〉

    Chloride conductance expressed by delta F508 and other mutant CFTRs in Xenopus oocytes (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-12-20
    Description: The cystic fibrosis transmembrane conductance regulator (CFTR) is associated with expression of a chloride conductance that is defective in cystic fibrosis (CF). Xenopus oocytes injected with RNA coding for CFTR that contained mutations in the first nucleotide binding fold (NBF1) expressed chloride currents in response to raising adenosine 3',5'-monophosphate (cAMP) with forskolin and 3-isobutyl-1-methylxanthine (IBMX). The mutant CFTRs were less sensitive than wild-type CFTR to this activating stimulus, and the reduction in sensitivity correlated with the severity of cystic fibrosis in patients carrying the corresponding mutations. This demonstration provides the basis for detailed analyses of NBF1 function and suggests potential pharmacologic treatments for cystic fibrosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drumm, M L -- Wilkinson, D J -- Smit, L S -- Worrell, R T -- Strong, T V -- Frizzell, R A -- Dawson, D C -- Collins, F S -- DK29786/DK/NIDDK NIH HHS/ -- DK39690/DK/NIDDK NIH HHS/ -- DK42718/DK/NIDDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1797-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1722350" target="_blank"〉PubMed〈/a〉

    Analyses of pig genomes provide insight into porcine demography and evolution (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-11-16
    Description: For 10,000 years pigs and humans have shared a close and complex relationship. From domestication to modern breeding practices, humans have shaped the genomes of domestic pigs. Here we present the assembly and analysis of the genome sequence of a female domestic Duroc pig (Sus scrofa) and a comparison with the genomes of wild and domestic pigs from Europe and Asia. Wild pigs emerged in South East Asia and subsequently spread across Eurasia. Our results reveal a deep phylogenetic split between European and Asian wild boars approximately 1 million years ago, and a selective sweep analysis indicates selection on genes involved in RNA processing and regulation. Genes associated with immune response and olfaction exhibit fast evolution. Pigs have the largest repertoire of functional olfactory receptor genes, reflecting the importance of smell in this scavenging animal. The pig genome sequence provides an important resource for further improvements of this important livestock species, and our identification of many putative disease-causing variants extends the potential of the pig as a biomedical model.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3566564/" 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/PMC3566564/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Groenen, Martien A M -- Archibald, Alan L -- Uenishi, Hirohide -- Tuggle, Christopher K -- Takeuchi, Yasuhiro -- Rothschild, Max F -- Rogel-Gaillard, Claire -- Park, Chankyu -- Milan, Denis -- Megens, Hendrik-Jan -- Li, Shengting -- Larkin, Denis M -- Kim, Heebal -- Frantz, Laurent A F -- Caccamo, Mario -- Ahn, Hyeonju -- Aken, Bronwen L -- Anselmo, Anna -- Anthon, Christian -- Auvil, Loretta -- Badaoui, Bouabid -- Beattie, Craig W -- Bendixen, Christian -- Berman, Daniel -- Blecha, Frank -- Blomberg, Jonas -- Bolund, Lars -- Bosse, Mirte -- Botti, Sara -- Bujie, Zhan -- Bystrom, Megan -- Capitanu, Boris -- Carvalho-Silva, Denise -- Chardon, Patrick -- Chen, Celine -- Cheng, Ryan -- Choi, Sang-Haeng -- Chow, William -- Clark, Richard C -- Clee, Christopher -- Crooijmans, Richard P M A -- Dawson, Harry D -- Dehais, Patrice -- De Sapio, Fioravante -- Dibbits, Bert -- Drou, Nizar -- Du, Zhi-Qiang -- Eversole, Kellye -- Fadista, Joao -- Fairley, Susan -- Faraut, Thomas -- Faulkner, Geoffrey J -- Fowler, Katie E -- Fredholm, Merete -- Fritz, Eric -- Gilbert, James G R -- Giuffra, Elisabetta -- Gorodkin, Jan -- Griffin, Darren K -- Harrow, Jennifer L -- Hayward, Alexander -- Howe, Kerstin -- Hu, Zhi-Liang -- Humphray, Sean J -- Hunt, Toby -- Hornshoj, Henrik -- Jeon, Jin-Tae -- Jern, Patric -- Jones, Matthew -- Jurka, Jerzy -- Kanamori, Hiroyuki -- Kapetanovic, Ronan -- Kim, Jaebum -- Kim, Jae-Hwan -- Kim, Kyu-Won -- Kim, Tae-Hun -- Larson, Greger -- Lee, Kyooyeol -- Lee, Kyung-Tai -- Leggett, Richard -- Lewin, Harris A -- Li, Yingrui -- Liu, Wansheng -- Loveland, Jane E -- Lu, Yao -- Lunney, Joan K -- Ma, Jian -- Madsen, Ole -- Mann, Katherine -- Matthews, Lucy -- McLaren, Stuart -- Morozumi, Takeya -- Murtaugh, Michael P -- Narayan, Jitendra -- Nguyen, Dinh Truong -- Ni, Peixiang -- Oh, Song-Jung -- Onteru, Suneel -- Panitz, Frank -- Park, Eung-Woo -- Park, Hong-Seog -- Pascal, Geraldine -- Paudel, Yogesh -- Perez-Enciso, Miguel -- Ramirez-Gonzalez, Ricardo -- Reecy, James M -- Rodriguez-Zas, Sandra -- Rohrer, Gary A -- Rund, Lauretta -- Sang, Yongming -- Schachtschneider, Kyle -- Schraiber, Joshua G -- Schwartz, John -- Scobie, Linda -- Scott, Carol -- Searle, Stephen -- Servin, Bertrand -- Southey, Bruce R -- Sperber, Goran -- Stadler, Peter -- Sweedler, Jonathan V -- Tafer, Hakim -- Thomsen, Bo -- Wali, Rashmi -- Wang, Jian -- Wang, Jun -- White, Simon -- Xu, Xun -- Yerle, Martine -- Zhang, Guojie -- Zhang, Jianguo -- Zhang, Jie -- Zhao, Shuhong -- Rogers, Jane -- Churcher, Carol -- Schook, Lawrence B -- 095908/Wellcome Trust/United Kingdom -- 249894/European Research Council/International -- 5 P41 LM006252/LM/NLM NIH HHS/ -- 5 P41LM006252/LM/NLM NIH HHS/ -- BB/E010520/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E010520/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E010768/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E011640/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G004013/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/H005935/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025328/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0900950/Medical Research Council/United Kingdom -- P20-RR017686/RR/NCRR NIH HHS/ -- P30 DA018310/DA/NIDA NIH HHS/ -- R13 RR020283A/RR/NCRR NIH HHS/ -- R13 RR032267A/RR/NCRR NIH HHS/ -- R21 DA027548/DA/NIDA NIH HHS/ -- R21 HG006464/HG/NHGRI NIH HHS/ -- T32 AI083196/AI/NIAID NIH HHS/ -- England -- Nature. 2012 Nov 15;491(7424):393-8. doi: 10.1038/nature11622.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Animal Breeding and Genomics Centre, Wageningen University, De Elst 1, 6708 WD, Wageningen, The Netherlands. martien.groenen@wur.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23151582" target="_blank"〉PubMed〈/a〉

    Inhibition of BET recruitment to chromatin as an effective treatment for MLL-fusion leukaemia (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-10-04
    Description: Recurrent chromosomal translocations involving the mixed lineage leukaemia (MLL) gene initiate aggressive forms of leukaemia, which are often refractory to conventional therapies. Many MLL-fusion partners are members of the super elongation complex (SEC), a critical regulator of transcriptional elongation, suggesting that aberrant control of this process has an important role in leukaemia induction. Here we use a global proteomic strategy to demonstrate that MLL fusions, as part of SEC and the polymerase-associated factor complex (PAFc), are associated with the BET family of acetyl-lysine recognizing, chromatin 'adaptor' proteins. These data provided the basis for therapeutic intervention in MLL-fusion leukaemia, via the displacement of the BET family of proteins from chromatin. We show that a novel small molecule inhibitor of the BET family, GSK1210151A (I-BET151), has profound efficacy against human and murine MLL-fusion leukaemic cell lines, through the induction of early cell cycle arrest and apoptosis. I-BET151 treatment in two human leukaemia cell lines with different MLL fusions alters the expression of a common set of genes whose function may account for these phenotypic changes. The mode of action of I-BET151 is, at least in part, due to the inhibition of transcription at key genes (BCL2, C-MYC and CDK6) through the displacement of BRD3/4, PAFc and SEC components from chromatin. In vivo studies indicate that I-BET151 has significant therapeutic value, providing survival benefit in two distinct mouse models of murine MLL-AF9 and human MLL-AF4 leukaemia. Finally, the efficacy of I-BET151 against human leukaemia stem cells is demonstrated, providing further evidence of its potent therapeutic potential. These findings establish the displacement of BET proteins from chromatin as a promising epigenetic therapy for these aggressive leukaemias.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3679520/" 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/PMC3679520/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, Mark A -- Prinjha, Rab K -- Dittmann, Antje -- Giotopoulos, George -- Bantscheff, Marcus -- Chan, Wai-In -- Robson, Samuel C -- Chung, Chun-wa -- Hopf, Carsten -- Savitski, Mikhail M -- Huthmacher, Carola -- Gudgin, Emma -- Lugo, Dave -- Beinke, Soren -- Chapman, Trevor D -- Roberts, Emma J -- Soden, Peter E -- Auger, Kurt R -- Mirguet, Olivier -- Doehner, Konstanze -- Delwel, Ruud -- Burnett, Alan K -- Jeffrey, Phillip -- Drewes, Gerard -- Lee, Kevin -- Huntly, Brian J P -- Kouzarides, Tony -- 092096/Wellcome Trust/United Kingdom -- G0800784/Medical Research Council/United Kingdom -- G116/187/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- England -- Nature. 2011 Oct 2;478(7370):529-33. doi: 10.1038/nature10509.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Haematology, Cambridge Institute for Medical Research and Addenbrookes Hospital, University of Cambridge, Cambridge CB2 0XY, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21964340" target="_blank"〉PubMed〈/a〉

    Integrating abundance and functional traits reveals new global hotspots of fish diversity (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-09-27
    Description: Species richness has dominated our view of global biodiversity patterns for centuries. The dominance of this paradigm is reflected in the focus by ecologists and conservation managers on richness and associated occurrence-based measures for understanding drivers of broad-scale diversity patterns and as a biological basis for management. However, this is changing rapidly, as it is now recognized that not only the number of species but the species present, their phenotypes and the number of individuals of each species are critical in determining the nature and strength of the relationships between species diversity and a range of ecological functions (such as biomass production and nutrient cycling). Integrating these measures should provide a more relevant representation of global biodiversity patterns in terms of ecological functions than that provided by simple species counts. Here we provide comparisons of a traditional global biodiversity distribution measure based on richness with metrics that incorporate species abundances and functional traits. We use data from standardized quantitative surveys of 2,473 marine reef fish species at 1,844 sites, spanning 133 degrees of latitude from all ocean basins, to identify new diversity hotspots in some temperate regions and the tropical eastern Pacific Ocean. These relate to high diversity of functional traits amongst individuals in the community (calculated using Rao's Q), and differ from previously reported patterns in functional diversity and richness for terrestrial animals, which emphasize species-rich tropical regions only. There is a global trend for greater evenness in the number of individuals of each species, across the reef fish species observed at sites ('community evenness'), at higher latitudes. This contributes to the distribution of functional diversity hotspots and contrasts with well-known latitudinal gradients in richness. Our findings suggest that the contribution of species diversity to a range of ecosystem functions varies over large scales, and imply that in tropical regions, which have higher numbers of species, each species contributes proportionally less to community-level ecological processes on average than species in temperate regions. Metrics of ecological function usefully complement metrics of species diversity in conservation management, including when identifying planning priorities and when tracking changes to biodiversity values.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stuart-Smith, Rick D -- Bates, Amanda E -- Lefcheck, Jonathan S -- Duffy, J Emmett -- Baker, Susan C -- Thomson, Russell J -- Stuart-Smith, Jemina F -- Hill, Nicole A -- Kininmonth, Stuart J -- Airoldi, Laura -- Becerro, Mikel A -- Campbell, Stuart J -- Dawson, Terence P -- Navarrete, Sergio A -- Soler, German A -- Strain, Elisabeth M A -- Willis, Trevor J -- Edgar, Graham J -- England -- Nature. 2013 Sep 26;501(7468):539-42. doi: 10.1038/nature12529.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Marine and Antarctic Studies, University of Tasmania, Private Bag 49, Hobart, Tasmania 7001, Australia. rstuarts@utas.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24067714" target="_blank"〉PubMed〈/a〉

    Beta-adrenergic receptor kinase-2 and beta-arrestin-2 as mediators of odorant-induced desensitization (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-02-05
    Description: beta-Adrenergic receptor kinase (beta ARK) and beta-arrestin function in the homologous or agonist-activated desensitization of G protein-coupled receptors. The isoforms beta ARK-2 and beta-arrestin-2 are highly enriched in and localized to the dendritic knobs and cilia of the olfactory receptor neurons where the initial events of olfactory signal transduction occur. Odorants induce a rapid and transient elevation of adenosine 3',5'-monophosphate (cAMP), which activates a nonspecific cation channel and produces membrane depolarization. Preincubation of rat olfactory cilia with antibodies raised against beta ARK-2 and beta-arrestin-2 increased the odorant-induced elevation of cAMP and attenuated desensitization. These results suggest that beta ARK-2 and beta-arrestin-2 mediate agonist-dependent desensitization in olfaction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, T M -- Arriza, J L -- Jaworsky, D E -- Borisy, F F -- Attramadal, H -- Lefkowitz, R J -- Ronnett, G V -- NS 01578-01/NS/NINDS NIH HHS/ -- NS-02131/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1993 Feb 5;259(5096):825-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Johns Hopkins Medical Institutions, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8381559" target="_blank"〉PubMed〈/a〉

    Endothelial NOS and the blockade of LTP by NOS inhibitors in mice lacking neuronal NOS (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-22
    Description: Long-term potentiation (LTP) is a persistent increase in synaptic strength implicated in certain forms of learning and memory. In the CA1 region of the hippocampus, LTP is thought to involve the release of one or more retrograde messengers from the postsynaptic cell that act on the presynaptic terminal to enhance transmitter release. One candidate retrograde messenger is the membrane-permeant gas nitric oxide (NO), which in the brain is released after activation of the neuronal-specific NO synthase isoform (nNOS). To assess the importance of NO in hippocampal synaptic plasticity, LTP was examined in mice where the gene encoding nNOS was disrupted by gene targeting. In nNOS- mice, LTP induced by weak intensity tetanic stimulation was normal except for a slight reduction in comparison to that in wild-type mice and was blocked by NOS inhibitors, just as it was in wild-type mice. Immunocytochemical studies indicate that in the nNOS- mice as in wild-type mice, the endothelial form of NOS (eNOS) is expressed in CA1 neurons. These findings suggest that eNOS, rather than nNOS, generates NO within the postsynaptic cell during LTP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Dell, T J -- Huang, P L -- Dawson, T M -- Dinerman, J L -- Snyder, S H -- Kandel, E R -- Fishman, M C -- DA-00074/DA/NIDA NIH HHS/ -- DA-00266/DA/NIDA NIH HHS/ -- MH-45923/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jul 22;265(5171):542-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, College of Physicians and Surgeons of Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7518615" target="_blank"〉PubMed〈/a〉

    Retinoids selective for retinoid X receptor response pathways (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-12-18
    Description: Retinoids have a broad spectrum of biological activities and are useful therapeutic agents. Their physiological activities are mediated by two types of receptors, the retinoic acid receptors (RARs) and the retinoid X receptors (RXRs). RARs, as well as several related receptors, require heterodimerization with RXRs for effective DNA binding and function. However, in the presence of 9-cis-retinoic acid, a ligand for both RARs and RXRs, RXRs can also form homodimers. A series of retinoids is reported that selectively activates RXR homodimers but does not affect RAR-RXR heterodimers and thus demonstrates that both retinoid response pathways can be independently activated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lehmann, J M -- Jong, L -- Fanjul, A -- Cameron, J F -- Lu, X P -- Haefner, P -- Dawson, M I -- Pfahl, M -- CA50676/CA/NCI NIH HHS/ -- P01 CA51993/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Dec 18;258(5090):1944-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Center, La Jolla Cancer Research Foundation, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1335166" target="_blank"〉PubMed〈/a〉
