    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 More recently, it has been replaced by synthetic derivatives such as aspirin and salsalate, both of which are rapidly broken down to salicylate in vivo.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.

    Condition-dependent transcriptome reveals high-level regulatory architecture in Bacillus subtilis (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-03
    Description: Bacteria adapt to environmental stimuli by adjusting their transcriptomes in a complex manner, the full potential of which has yet to be established for any individual bacterial species. Here, we report the transcriptomes of Bacillus subtilis exposed to a wide range of environmental and nutritional conditions that the organism might encounter in nature. We comprehensively mapped transcription units (TUs) and grouped 2935 promoters into regulons controlled by various RNA polymerase sigma factors, accounting for ~66% of the observed variance in transcriptional activity. This global classification of promoters and detailed description of TUs revealed that a large proportion of the detected antisense RNAs arose from potentially spurious transcription initiation by alternative sigma factors and from imperfect control of transcription termination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicolas, Pierre -- Mader, Ulrike -- Dervyn, Etienne -- Rochat, Tatiana -- Leduc, Aurelie -- Pigeonneau, Nathalie -- Bidnenko, Elena -- Marchadier, Elodie -- Hoebeke, Mark -- Aymerich, Stephane -- Becher, Dorte -- Bisicchia, Paola -- Botella, Eric -- Delumeau, Olivier -- Doherty, Geoff -- Denham, Emma L -- Fogg, Mark J -- Fromion, Vincent -- Goelzer, Anne -- Hansen, Annette -- Hartig, Elisabeth -- Harwood, Colin R -- Homuth, Georg -- Jarmer, Hanne -- Jules, Matthieu -- Klipp, Edda -- Le Chat, Ludovic -- Lecointe, Francois -- Lewis, Peter -- Liebermeister, Wolfram -- March, Anika -- Mars, Ruben A T -- Nannapaneni, Priyanka -- Noone, David -- Pohl, Susanne -- Rinn, Bernd -- Rugheimer, Frank -- Sappa, Praveen K -- Samson, Franck -- Schaffer, Marc -- Schwikowski, Benno -- Steil, Leif -- Stulke, Jorg -- Wiegert, Thomas -- Devine, Kevin M -- Wilkinson, Anthony J -- van Dijl, Jan Maarten -- Hecker, Michael -- Volker, Uwe -- Bessieres, Philippe -- Noirot, Philippe -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1103-6. doi: 10.1126/science.1206848.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INRA, UR1077, Mathematique Informatique et Genome, Jouy-en-Josas, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22383849" target="_blank"〉PubMed〈/a〉

    Cryo-EM structure of a fully glycosylated soluble cleaved HIV-1 envelope trimer (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-11-02
    Description: The HIV-1 envelope glycoprotein (Env) trimer contains the receptor binding sites and membrane fusion machinery that introduce the viral genome into the host cell. As the only target for broadly neutralizing antibodies (bnAbs), Env is a focus for rational vaccine design. We present a cryo-electron microscopy reconstruction and structural model of a cleaved, soluble Env trimer (termed BG505 SOSIP.664 gp140) in complex with a CD4 binding site (CD4bs) bnAb, PGV04, at 5.8 angstrom resolution. The structure reveals the spatial arrangement of Env components, including the V1/V2, V3, HR1, and HR2 domains, as well as shielding glycans. The structure also provides insights into trimer assembly, gp120-gp41 interactions, and the CD4bs epitope cluster for bnAbs, which covers a more extensive area and defines a more complex site of vulnerability than previously described.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3954647/" 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/PMC3954647/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lyumkis, Dmitry -- Julien, Jean-Philippe -- de Val, Natalia -- Cupo, Albert -- Potter, Clinton S -- Klasse, Per-Johan -- Burton, Dennis R -- Sanders, Rogier W -- Moore, John P -- Carragher, Bridget -- Wilson, Ian A -- Ward, Andrew B -- GM103310/GM/NIGMS NIH HHS/ -- P01 AI082362/AI/NIAID NIH HHS/ -- P01 AI82362/AI/NIAID NIH HHS/ -- P41 GM103310/GM/NIGMS NIH HHS/ -- R01 AI084817/AI/NIAID NIH HHS/ -- R01 AI36082/AI/NIAID NIH HHS/ -- R37 AI036082/AI/NIAID NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2013 Dec 20;342(6165):1484-90. doi: 10.1126/science.1245627.

    Structural basis for molecular recognition at serotonin receptors (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-23
    Description: Serotonin or 5-hydroxytryptamine (5-HT) regulates a wide spectrum of human physiology through the 5-HT receptor family. We report the crystal structures of the human 5-HT1B G protein-coupled receptor bound to the agonist antimigraine medications ergotamine and dihydroergotamine. The structures reveal similar binding modes for these ligands, which occupy the orthosteric pocket and an extended binding pocket close to the extracellular loops. The orthosteric pocket is formed by residues conserved in the 5-HT receptor family, clarifying the family-wide agonist activity of 5-HT. Compared with the structure of the 5-HT2B receptor, the 5-HT1B receptor displays a 3 angstrom outward shift at the extracellular end of helix V, resulting in a more open extended pocket that explains subtype selectivity. Together with docking and mutagenesis studies, these structures provide a comprehensive structural basis for understanding receptor-ligand interactions and designing subtype-selective serotonergic drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3644373/" 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/PMC3644373/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Chong -- Jiang, Yi -- Ma, Jinming -- Wu, Huixian -- Wacker, Daniel -- Katritch, Vsevolod -- Han, Gye Won -- Liu, Wei -- Huang, Xi-Ping -- Vardy, Eyal -- McCorvy, John D -- Gao, Xiang -- Zhou, X Edward -- Melcher, Karsten -- Zhang, Chenghai -- Bai, Fang -- Yang, Huaiyu -- Yang, Linlin -- Jiang, Hualiang -- Roth, Bryan L -- Cherezov, Vadim -- Stevens, Raymond C -- Xu, H Eric -- P50 GM073197/GM/NIGMS NIH HHS/ -- R01 DA027170/DA/NIDA NIH HHS/ -- R01 DA27170/DA/NIDA NIH HHS/ -- R01 DK071662/DK/NIDDK NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- R01 MH61887/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- U19 MH82441/MH/NIMH NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 May 3;340(6132):610-4. doi: 10.1126/science.1232807.

    Extensive variation in chromatin states across humans (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-10-19
    Description: The majority of disease-associated variants lie outside protein-coding regions, suggesting a link between variation in regulatory regions and disease predisposition. We studied differences in chromatin states using five histone modifications, cohesin, and CTCF in lymphoblastoid lines from 19 individuals of diverse ancestry. We found extensive signal variation in regulatory regions, which often switch between active and repressed states across individuals. Enhancer activity is particularly diverse among individuals, whereas gene expression remains relatively stable. Chromatin variability shows genetic inheritance in trios, correlates with genetic variation and population divergence, and is associated with disruptions of transcription factor binding motifs. Overall, our results provide insights into chromatin variation among humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4075767/" 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/PMC4075767/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasowski, Maya -- Kyriazopoulou-Panagiotopoulou, Sofia -- Grubert, Fabian -- Zaugg, Judith B -- Kundaje, Anshul -- Liu, Yuling -- Boyle, Alan P -- Zhang, Qiangfeng Cliff -- Zakharia, Fouad -- Spacek, Damek V -- Li, Jingjing -- Xie, Dan -- Olarerin-George, Anthony -- Steinmetz, Lars M -- Hogenesch, John B -- Kellis, Manolis -- Batzoglou, Serafim -- Snyder, Michael -- R01 HG004037/HG/NHGRI NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- T32 HG000044/HG/NHGRI NIH HHS/ -- T32GM07205/GM/NIGMS NIH HHS/ -- U01 HL107393/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 8;342(6159):750-2. doi: 10.1126/science.1242510.

    Probing allostery through DNA (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-16
    Description: Allostery is well documented for proteins but less recognized for DNA-protein interactions. Here, we report that specific binding of a protein on DNA is substantially stabilized or destabilized by another protein bound nearby. The ternary complex's free energy oscillates as a function of the separation between the two proteins with a periodicity of ~10 base pairs, the helical pitch of B-form DNA, and a decay length of ~15 base pairs. The binding affinity of a protein near a DNA hairpin is similarly dependent on their separation, which-together with molecular dynamics simulations-suggests that deformation of the double-helical structure is the origin of DNA allostery. The physiological relevance of this phenomenon is illustrated by its effect on gene expression in live bacteria and on a transcription factor's affinity near nucleosomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3586787/" 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/PMC3586787/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Sangjin -- Brostromer, Erik -- Xing, Dong -- Jin, Jianshi -- Chong, Shasha -- Ge, Hao -- Wang, Siyuan -- Gu, Chan -- Yang, Lijiang -- Gao, Yi Qin -- Su, Xiao-dong -- Sun, Yujie -- Xie, X Sunney -- DP1 OD000277/OD/NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 15;339(6121):816-9. doi: 10.1126/science.1229223.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23413354" target="_blank"〉PubMed〈/a〉

    Conspecific negative density dependence and forest diversity (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-19
    Description: Conspecific negative density-dependent establishment, in which local abundance negatively affects establishment of conspecific seedlings through host-specific enemies, can influence species diversity of plant communities, but the generality of this process is not well understood. We tested the strength of density dependence using the United States Forest Service's Forest Inventory and Analysis database containing 151 species from more than 200,000 forest plots spanning 4,000,000 square kilometers. We found that most species experienced conspecific negative density dependence (CNDD), but there was little effect of heterospecific density. Additionally, abundant species exhibited weaker CNDD than rarer species, and species-rich regions exhibited stronger CNDD than species-poor regions. Collectively, our results provide evidence that CNDD is a pervasive mechanism driving diversity across a gradient from boreal to subtropical forests.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, Daniel J -- Beaulieu, Wesley T -- Bever, James D -- Clay, Keith -- New York, N.Y. -- Science. 2012 May 18;336(6083):904-7. doi: 10.1126/science.1220269.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Indiana University, Bloomington, IN 47405, USA. dj4@indiana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22605774" target="_blank"〉PubMed〈/a〉

    Structural features for functional selectivity at serotonin receptors (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-23
    Description: Drugs active at G protein-coupled receptors (GPCRs) can differentially modulate either canonical or noncanonical signaling pathways via a phenomenon known as functional selectivity or biased signaling. We report biochemical studies showing that the hallucinogen lysergic acid diethylamide, its precursor ergotamine (ERG), and related ergolines display strong functional selectivity for beta-arrestin signaling at the 5-HT2B 5-hydroxytryptamine (5-HT) receptor, whereas they are relatively unbiased at the 5-HT1B receptor. To investigate the structural basis for biased signaling, we determined the crystal structure of the human 5-HT2B receptor bound to ERG and compared it with the 5-HT1B/ERG structure. Given the relatively poor understanding of GPCR structure and function to date, insight into different GPCR signaling pathways is important to better understand both adverse and favorable therapeutic activities.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3644390/" 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/PMC3644390/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wacker, Daniel -- Wang, Chong -- Katritch, Vsevolod -- Han, Gye Won -- Huang, Xi-Ping -- Vardy, Eyal -- McCorvy, John D -- Jiang, Yi -- Chu, Meihua -- Siu, Fai Yiu -- Liu, Wei -- Xu, H Eric -- Cherezov, Vadim -- Roth, Bryan L -- Stevens, Raymond C -- P50 GM073197/GM/NIGMS NIH HHS/ -- R01 DK071662/DK/NIDDK NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- R01 MH61887/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- U19 MH82441/MH/NIMH NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 May 3;340(6132):615-9. doi: 10.1126/science.1232808.
