    Sequence and structural convergence of broad and potent HIV antibodies that mimic CD4 binding (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-19
    Description: Passive transfer of broadly neutralizing HIV antibodies can prevent infection, which suggests that vaccines that elicit such antibodies would be protective. Thus far, however, few broadly neutralizing HIV antibodies that occur naturally have been characterized. To determine whether these antibodies are part of a larger group of related molecules, we cloned 576 new HIV antibodies from four unrelated individuals. All four individuals produced expanded clones of potent broadly neutralizing CD4-binding-site antibodies that mimic binding to CD4. Despite extensive hypermutation, the new antibodies shared a consensus sequence of 68 immunoglobulin H (IgH) chain amino acids and arise independently from two related IgH genes. Comparison of the crystal structure of one of the antibodies to the broadly neutralizing antibody VRC01 revealed conservation of the contacts to the HIV spike.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3351836/" 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/PMC3351836/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheid, Johannes F -- Mouquet, Hugo -- Ueberheide, Beatrix -- Diskin, Ron -- Klein, Florian -- Oliveira, Thiago Y K -- Pietzsch, John -- Fenyo, David -- Abadir, Alexander -- Velinzon, Klara -- Hurley, Arlene -- Myung, Sunnie -- Boulad, Farid -- Poignard, Pascal -- Burton, Dennis R -- Pereyra, Florencia -- Ho, David D -- Walker, Bruce D -- Seaman, Michael S -- Bjorkman, Pamela J -- Chait, Brian T -- Nussenzweig, Michel C -- P01 AI081677/AI/NIAID NIH HHS/ -- P30 AI060354/AI/NIAID NIH HHS/ -- R01 AI033292/AI/NIAID NIH HHS/ -- RR00862/RR/NCRR NIH HHS/ -- RR022220/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Sep 16;333(6049):1633-7. doi: 10.1126/science.1207227.

    Integrative annotation of variants from 1092 humans: application to cancer genomics (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-10-05
    Description: Interpreting variants, especially noncoding ones, in the increasing number of personal genomes is challenging. We used patterns of polymorphisms in functionally annotated regions in 1092 humans to identify deleterious variants; then we experimentally validated candidates. We analyzed both coding and noncoding regions, with the former corroborating the latter. We found regions particularly sensitive to mutations ("ultrasensitive") and variants that are disruptive because of mechanistic effects on transcription-factor binding (that is, "motif-breakers"). We also found variants in regions with higher network centrality tend to be deleterious. Insertions and deletions followed a similar pattern to single-nucleotide variants, with some notable exceptions (e.g., certain deletions and enhancers). On the basis of these patterns, we developed a computational tool (FunSeq), whose application to ~90 cancer genomes reveals nearly a hundred candidate noncoding drivers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3947637/" 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/PMC3947637/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Khurana, Ekta -- Fu, Yao -- Colonna, Vincenza -- Mu, Xinmeng Jasmine -- Kang, Hyun Min -- Lappalainen, Tuuli -- Sboner, Andrea -- Lochovsky, Lucas -- Chen, Jieming -- Harmanci, Arif -- Das, Jishnu -- Abyzov, Alexej -- Balasubramanian, Suganthi -- Beal, Kathryn -- Chakravarty, Dimple -- Challis, Daniel -- Chen, Yuan -- Clarke, Declan -- Clarke, Laura -- Cunningham, Fiona -- Evani, Uday S -- Flicek, Paul -- Fragoza, Robert -- Garrison, Erik -- Gibbs, Richard -- Gumus, Zeynep H -- Herrero, Javier -- Kitabayashi, Naoki -- Kong, Yong -- Lage, Kasper -- Liluashvili, Vaja -- Lipkin, Steven M -- MacArthur, Daniel G -- Marth, Gabor -- Muzny, Donna -- Pers, Tune H -- Ritchie, Graham R S -- Rosenfeld, Jeffrey A -- Sisu, Cristina -- Wei, Xiaomu -- Wilson, Michael -- Xue, Yali -- Yu, Fuli -- 1000 Genomes Project Consortium -- Dermitzakis, Emmanouil T -- Yu, Haiyuan -- Rubin, Mark A -- Tyler-Smith, Chris -- Gerstein, Mark -- 085532/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 095908/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- CA167824/CA/NCI NIH HHS/ -- G12 MD007579/MD/NIMHD NIH HHS/ -- G12 RR003050/RR/NCRR NIH HHS/ -- GM104424/GM/NIGMS NIH HHS/ -- HG005718/HG/NHGRI NIH HHS/ -- HG007000/HG/NHGRI NIH HHS/ -- P20 MD006899/MD/NIMHD NIH HHS/ -- R01 CA166661/CA/NCI NIH HHS/ -- R01 HG002898/HG/NHGRI NIH HHS/ -- R01CA152057/CA/NCI NIH HHS/ -- R01HG4719/HG/NHGRI NIH HHS/ -- U01 CA111275/CA/NCI NIH HHS/ -- U01 HG005718/HG/NHGRI NIH HHS/ -- U01HG6513/HG/NHGRI NIH HHS/ -- U41 HG007000/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- UL1 TR000457/TR/NCATS NIH HHS/ -- WT085532/Wellcome Trust/United Kingdom -- WT095908/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2013 Oct 4;342(6154):1235587. doi: 10.1126/science.1235587.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Computational Biology and Bioinformatics, Yale University, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24092746" target="_blank"〉PubMed〈/a〉

    The genetic map of Artemisia annua L. identifies loci affecting yield of the antimalarial drug artemisinin (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-16
    Description: Artemisinin is a plant natural product produced by Artemisia annua and the active ingredient in the most effective treatment for malaria. Efforts to eradicate malaria are increasing demand for an affordable, high-quality, robust supply of artemisinin. We performed deep sequencing on the transcriptome of A. annua to identify genes and markers for fast-track breeding. Extensive genetic variation enabled us to build a detailed genetic map with nine linkage groups. Replicated field trials resulted in a quantitative trait loci (QTL) map that accounts for a significant amount of the variation in key traits controlling artemisinin yield. Enrichment for positive QTLs in parents of new high-yielding hybrids confirms that the knowledge and tools to convert A. annua into a robust crop are now available.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graham, Ian A -- Besser, Katrin -- Blumer, Susan -- Branigan, Caroline A -- Czechowski, Tomasz -- Elias, Luisa -- Guterman, Inna -- Harvey, David -- Isaac, Peter G -- Khan, Awais M -- Larson, Tony R -- Li, Yi -- Pawson, Tanya -- Penfield, Teresa -- Rae, Anne M -- Rathbone, Deborah A -- Reid, Sonja -- Ross, Joe -- Smallwood, Margaret F -- Segura, Vincent -- Townsend, Theresa -- Vyas, Darshna -- Winzer, Thilo -- Bowles, Dianna -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):328-31. doi: 10.1126/science.1182612.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Novel Agricultural Products, Department of Biology, University of York, York YO10 5YW, UK. iag1@york.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075252" target="_blank"〉PubMed〈/a〉

    Genotype to phenotype: a complex problem (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-24
    Description: We generated a high-resolution whole-genome sequence and individually deleted 5100 genes in Sigma1278b, a Saccharomyces cerevisiae strain closely related to reference strain S288c. Similar to the variation between human individuals, Sigma1278b and S288c average 3.2 single-nucleotide polymorphisms per kilobase. A genome-wide comparison of deletion mutant phenotypes identified a subset of genes that were conditionally essential by strain, including 44 essential genes unique to Sigma1278b and 13 unique to S288c. Genetic analysis indicates the conditional phenotype was most often governed by complex genetic interactions, depending on multiple background-specific modifiers. Our comprehensive analysis suggests that the presence of a complex set of modifiers will often underlie the phenotypic differences between individuals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4412269/" 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/PMC4412269/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dowell, Robin D -- Ryan, Owen -- Jansen, An -- Cheung, Doris -- Agarwala, Sudeep -- Danford, Timothy -- Bernstein, Douglas A -- Rolfe, P Alexander -- Heisler, Lawrence E -- Chin, Brian -- Nislow, Corey -- Giaever, Guri -- Phillips, Patrick C -- Fink, Gerald R -- Gifford, David K -- Boone, Charles -- DK076284/DK/NIDDK NIH HHS/ -- GM035010/GM/NIGMS NIH HHS/ -- GM069676/GM/NIGMS NIH HHS/ -- P01 NS055923/NS/NINDS NIH HHS/ -- R01 GM035010/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):469. doi: 10.1126/science.1189015.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Computer Science and Artificial Intelligence Laboratory, Department of Electrical Engineering and Computer Science, Massachusetts Institute of Technology (MIT), Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413493" target="_blank"〉PubMed〈/a〉

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

    Publication Date: 2010-10-12
    Description: Bacterial biofilms are structured multicellular communities involved in a broad range of infections. Knowing how free-swimming bacteria adapt their motility mechanisms near surfaces is crucial for understanding the transition between planktonic and biofilm phenotypes. By translating microscopy movies into searchable databases of bacterial behavior, we identified fundamental type IV pili-driven mechanisms for Pseudomonas aeruginosa surface motility involved in distinct foraging strategies. Bacteria stood upright and "walked" with trajectories optimized for two-dimensional surface exploration. Vertical orientation facilitated surface detachment and could influence biofilm morphology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibiansky, Maxsim L -- Conrad, Jacinta C -- Jin, Fan -- Gordon, Vernita D -- Motto, Dominick A -- Mathewson, Margie A -- Stopka, Wiktor G -- Zelasko, Daria C -- Shrout, Joshua D -- Wong, Gerard C L -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):197. doi: 10.1126/science.1194238.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioengineering, California Nano Systems Institute,University of California, Los Angeles, CA 90024, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929769" target="_blank"〉PubMed〈/a〉

    The potential for respiratory droplet-transmissible A/H5N1 influenza virus to evolve in a mammalian host (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-23
    Description: Avian A/H5N1 influenza viruses pose a pandemic threat. As few as five amino acid substitutions, or four with reassortment, might be sufficient for mammal-to-mammal transmission through respiratory droplets. From surveillance data, we found that two of these substitutions are common in A/H5N1 viruses, and thus, some viruses might require only three additional substitutions to become transmissible via respiratory droplets between mammals. We used a mathematical model of within-host virus evolution to study factors that could increase and decrease the probability of the remaining substitutions evolving after the virus has infected a mammalian host. These factors, combined with the presence of some of these substitutions in circulating strains, make a virus evolving in nature a potentially serious threat. These results highlight critical areas in which more data are needed for assessing, and potentially averting, this threat.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3426314/" 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/PMC3426314/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Russell, Colin A -- Fonville, Judith M -- Brown, Andre E X -- Burke, David F -- Smith, David L -- James, Sarah L -- Herfst, Sander -- van Boheemen, Sander -- Linster, Martin -- Schrauwen, Eefje J -- Katzelnick, Leah -- Mosterin, Ana -- Kuiken, Thijs -- Maher, Eileen -- Neumann, Gabriele -- Osterhaus, Albert D M E -- Kawaoka, Yoshihiro -- Fouchier, Ron A M -- Smith, Derek J -- DP1 OD000490/OD/NIH HHS/ -- DP1-OD000490-01/OD/NIH HHS/ -- HHSN266200700010C/AI/NIAID NIH HHS/ -- HHSN266200700010C/PHS HHS/ -- R01 AI 069274/AI/NIAID NIH HHS/ -- R56 AI069274/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1541-7. doi: 10.1126/science.1222526.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, Cambridge, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22723414" target="_blank"〉PubMed〈/a〉

    Spatial and temporal diversity in genomic instability processes defines lung cancer evolution (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-10-11
    Description: Spatial and temporal dissection of the genomic changes occurring during the evolution of human non-small cell lung cancer (NSCLC) may help elucidate the basis for its dismal prognosis. We sequenced 25 spatially distinct regions from seven operable NSCLCs and found evidence of branched evolution, with driver mutations arising before and after subclonal diversification. There was pronounced intratumor heterogeneity in copy number alterations, translocations, and mutations associated with APOBEC cytidine deaminase activity. Despite maintained carcinogen exposure, tumors from smokers showed a relative decrease in smoking-related mutations over time, accompanied by an increase in APOBEC-associated mutations. In tumors from former smokers, genome-doubling occurred within a smoking-signature context before subclonal diversification, which suggested that a long period of tumor latency had preceded clinical detection. The regionally separated driver mutations, coupled with the relentless and heterogeneous nature of the genome instability processes, are likely to confound treatment success in NSCLC.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4636050/" 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/PMC4636050/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Bruin, Elza C -- McGranahan, Nicholas -- Mitter, Richard -- Salm, Max -- Wedge, David C -- Yates, Lucy -- Jamal-Hanjani, Mariam -- Shafi, Seema -- Murugaesu, Nirupa -- Rowan, Andrew J -- Gronroos, Eva -- Muhammad, Madiha A -- Horswell, Stuart -- Gerlinger, Marco -- Varela, Ignacio -- Jones, David -- Marshall, John -- Voet, Thierry -- Van Loo, Peter -- Rassl, Doris M -- Rintoul, Robert C -- Janes, Sam M -- Lee, Siow-Ming -- Forster, Martin -- Ahmad, Tanya -- Lawrence, David -- Falzon, Mary -- Capitanio, Arrigo -- Harkins, Timothy T -- Lee, Clarence C -- Tom, Warren -- Teefe, Enock -- Chen, Shann-Ching -- Begum, Sharmin -- Rabinowitz, Adam -- Phillimore, Benjamin -- Spencer-Dene, Bradley -- Stamp, Gordon -- Szallasi, Zoltan -- Matthews, Nik -- Stewart, Aengus -- Campbell, Peter -- Swanton, Charles -- 088340/Wellcome Trust/United Kingdom -- 091730/Wellcome Trust/United Kingdom -- 105104/Wellcome Trust/United Kingdom -- A11590/Cancer Research UK/United Kingdom -- A17786/Cancer Research UK/United Kingdom -- A19310/Cancer Research UK/United Kingdom -- A4688/Cancer Research UK/United Kingdom -- Cancer Research UK/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Oct 10;346(6206):251-6. doi: 10.1126/science.1253462.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Research UK Lung Cancer Centre of Excellence, University College London Cancer Institute, London WC1E 6BT, UK. ; Cancer Research UK London Research Institute, London WC2A 3LY, UK.

    Drug resistance. K13-propeller mutations confer artemisinin resistance in Plasmodium falciparum clinical isolates (2014)

    Description: The emergence of artemisinin resistance in Southeast Asia imperils efforts to reduce the global malaria burden. We genetically modified the Plasmodium falciparum K13 locus using zinc-finger nucleases and measured ring-stage survival rates after drug exposure in vitro; these rates correlate with parasite clearance half-lives in artemisinin-treated patients. With isolates from Cambodia, where resistance first emerged, survival rates decreased from 13 to 49% to 0.3 to 2.4% after the removal of K13 mutations. Conversely, survival rates in wild-type parasites increased from 〈/=0.6% to 2 to 29% after the insertion of K13 mutations. These mutations conferred elevated resistance to recent Cambodian isolates compared with that of reference lines, suggesting a contemporary contribution of additional genetic factors. Our data provide a conclusive rationale for worldwide K13-propeller sequencing to identify and eliminate artemisinin-resistant parasites.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4349400/" 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/PMC4349400/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Straimer, Judith -- Gnadig, Nina F -- Witkowski, Benoit -- Amaratunga, Chanaki -- Duru, Valentine -- Ramadani, Arba Pramundita -- Dacheux, Melanie -- Khim, Nimol -- Zhang, Lei -- Lam, Stephen -- Gregory, Philip D -- Urnov, Fyodor D -- Mercereau-Puijalon, Odile -- Benoit-Vical, Francoise -- Fairhurst, Rick M -- Menard, Didier -- Fidock, David A -- R01 AI109023/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2015 Jan 23;347(6220):428-31. doi: 10.1126/science.1260867.

    Rewiring of genetic networks in response to DNA damage (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-12-04
    Description: Although cellular behaviors are dynamic, the networks that govern these behaviors have been mapped primarily as static snapshots. Using an approach called differential epistasis mapping, we have discovered widespread changes in genetic interaction among yeast kinases, phosphatases, and transcription factors as the cell responds to DNA damage. Differential interactions uncover many gene functions that go undetected in static conditions. They are very effective at identifying DNA repair pathways, highlighting new damage-dependent roles for the Slt2 kinase, Pph3 phosphatase, and histone variant Htz1. The data also reveal that protein complexes are generally stable in response to perturbation, but the functional relations between these complexes are substantially reorganized. Differential networks chart a new type of genetic landscape that is invaluable for mapping cellular responses to stimuli.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3006187/" 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/PMC3006187/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bandyopadhyay, Sourav -- Mehta, Monika -- Kuo, Dwight -- Sung, Min-Kyung -- Chuang, Ryan -- Jaehnig, Eric J -- Bodenmiller, Bernd -- Licon, Katherine -- Copeland, Wilbert -- Shales, Michael -- Fiedler, Dorothea -- Dutkowski, Janusz -- Guenole, Aude -- van Attikum, Haico -- Shokat, Kevan M -- Kolodner, Richard D -- Huh, Won-Ki -- Aebersold, Ruedi -- Keogh, Michael-Christopher -- Krogan, Nevan J -- Ideker, Trey -- P30CA013330/CA/NCI NIH HHS/ -- P50 GM081879/GM/NIGMS NIH HHS/ -- R01 ES014811/ES/NIEHS NIH HHS/ -- R01 ES014811-01A1/ES/NIEHS NIH HHS/ -- R01 ES014811-02/ES/NIEHS NIH HHS/ -- R01 ES014811-02S1/ES/NIEHS NIH HHS/ -- R01 ES014811-03/ES/NIEHS NIH HHS/ -- R01 ES014811-04/ES/NIEHS NIH HHS/ -- R01 ES014811-05/ES/NIEHS NIH HHS/ -- R01 ES014811-05S1/ES/NIEHS NIH HHS/ -- R01 ES014811-06/ES/NIEHS NIH HHS/ -- R01 GM026017/GM/NIGMS NIH HHS/ -- R01 GM084279/GM/NIGMS NIH HHS/ -- R01 GM084279-01A1/GM/NIGMS NIH HHS/ -- R01 GM084279-02/GM/NIGMS NIH HHS/ -- R01 GM084279-02S1/GM/NIGMS NIH HHS/ -- R01 GM084279-03/GM/NIGMS NIH HHS/ -- R01 GM084279-04/GM/NIGMS NIH HHS/ -- R01 GM084448/GM/NIGMS NIH HHS/ -- R01-ES14811/ES/NIEHS NIH HHS/ -- R01-GM084279/GM/NIGMS NIH HHS/ -- R37 GM026017/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Dec 3;330(6009):1385-9. doi: 10.1126/science.1195618.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, San Diego, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21127252" target="_blank"〉PubMed〈/a〉
