Description: Epigenetic proteins are intently pursued targets in ligand discovery. So far, successful efforts have been limited to chromatin modifying enzymes, or so-called epigenetic 'writers' and 'erasers'. Potent inhibitors of histone binding modules have not yet been described. Here we report a cell-permeable small molecule (JQ1) that binds competitively to acetyl-lysine recognition motifs, or bromodomains. High potency and specificity towards a subset of human bromodomains is explained by co-crystal structures with bromodomain and extra-terminal (BET) family member BRD4, revealing excellent shape complementarity with the acetyl-lysine binding cavity. Recurrent translocation of BRD4 is observed in a genetically-defined, incurable subtype of human squamous carcinoma. Competitive binding by JQ1 displaces the BRD4 fusion oncoprotein from chromatin, prompting squamous differentiation and specific antiproliferative effects in BRD4-dependent cell lines and patient-derived xenograft models. These data establish proof-of-concept for targeting protein-protein interactions of epigenetic 'readers', and provide a versatile chemical scaffold for the development of chemical probes more broadly throughout the bromodomain family.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3010259/" 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/PMC3010259/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Filippakopoulos, Panagis -- Qi, Jun -- Picaud, Sarah -- Shen, Yao -- Smith, William B -- Fedorov, Oleg -- Morse, Elizabeth M -- Keates, Tracey -- Hickman, Tyler T -- Felletar, Ildiko -- Philpott, Martin -- Munro, Shonagh -- McKeown, Michael R -- Wang, Yuchuan -- Christie, Amanda L -- West, Nathan -- Cameron, Michael J -- Schwartz, Brian -- Heightman, Tom D -- La Thangue, Nicholas -- French, Christopher A -- Wiest, Olaf -- Kung, Andrew L -- Knapp, Stefan -- Bradner, James E -- 13058/Cancer Research UK/United Kingdom -- G0500905/Medical Research Council/United Kingdom -- G1000807/Medical Research Council/United Kingdom -- G9400953/Medical Research Council/United Kingdom -- K08 CA128972/CA/NCI NIH HHS/ -- K08 CA128972-03/CA/NCI NIH HHS/ -- T32-075762/PHS HHS/ -- Canadian Institutes of Health Research/Canada -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Dec 23;468(7327):1067-73. doi: 10.1038/nature09504.

Description: T helper cells that produce IL-17 (T(H)17 cells) promote autoimmunity in mice and have been implicated in the pathogenesis of human inflammatory diseases. At mucosal surfaces, T(H)17 cells are thought to protect the host from infection, whereas regulatory T (T(reg)) cells control immune responses and inflammation triggered by the resident microflora. Differentiation of both cell types requires transforming growth factor-beta (TGF-beta), but depends on distinct transcription factors: RORgammat (encoded by Rorc(gammat)) for T(H)17 cells and Foxp3 for T(reg) cells. How TGF-beta regulates the differentiation of T cells with opposing activities has been perplexing. Here we demonstrate that, together with pro-inflammatory cytokines, TGF-beta orchestrates T(H)17 cell differentiation in a concentration-dependent manner. At low concentrations, TGF-beta synergizes with interleukin (IL)-6 and IL-21 (refs 9-11) to promote IL-23 receptor (Il23r) expression, favouring T(H)17 cell differentiation. High concentrations of TGF-beta repress IL23r expression and favour Foxp3+ T(reg) cells. RORgammat and Foxp3 are co-expressed in naive CD4+ T cells exposed to TGF-beta and in a subset of T cells in the small intestinal lamina propria of the mouse. In vitro, TGF-beta-induced Foxp3 inhibits RORgammat function, at least in part through their interaction. Accordingly, lamina propria T cells that co-express both transcription factors produce less IL-17 (also known as IL-17a) than those that express RORgammat alone. IL-6, IL-21 and IL-23 relieve Foxp3-mediated inhibition of RORgammat, thereby promoting T(H)17 cell differentiation. Therefore, the decision of antigen-stimulated cells to differentiate into either T(H)17 or T(reg) cells depends on the cytokine-regulated balance of RORgammat and Foxp3.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2597437/" 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/PMC2597437/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Liang -- Lopes, Jared E -- Chong, Mark M W -- Ivanov, Ivaylo I -- Min, Roy -- Victora, Gabriel D -- Shen, Yuelei -- Du, Jianguang -- Rubtsov, Yuri P -- Rudensky, Alexander Y -- Ziegler, Steven F -- Littman, Dan R -- AI48779/AI/NIAID NIH HHS/ -- R01 AI048779/AI/NIAID NIH HHS/ -- R01 AI048779-05/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 May 8;453(7192):236-40. doi: 10.1038/nature06878.

Description: A novel H7N9 influenza A virus first detected in March 2013 has since caused more than 130 human infections in China, resulting in 40 deaths. Preliminary analyses suggest that the virus is a reassortant of H7, N9 and H9N2 avian influenza viruses, and carries some amino acids associated with mammalian receptor binding, raising concerns of a new pandemic. However, neither the source populations of the H7N9 outbreak lineage nor the conditions for its genesis are fully known. Using a combination of active surveillance, screening of virus archives, and evolutionary analyses, here we show that H7 viruses probably transferred from domestic duck to chicken populations in China on at least two independent occasions. We show that the H7 viruses subsequently reassorted with enzootic H9N2 viruses to generate the H7N9 outbreak lineage, and a related previously unrecognized H7N7 lineage. The H7N9 outbreak lineage has spread over a large geographic region and is prevalent in chickens at live poultry markets, which are thought to be the immediate source of human infections. Whether the H7N9 outbreak lineage has, or will, become enzootic in China and neighbouring regions requires further investigation. The discovery here of a related H7N7 influenza virus in chickens that has the ability to infect mammals experimentally, suggests that H7 viruses may pose threats beyond the current outbreak. The continuing prevalence of H7 viruses in poultry could lead to the generation of highly pathogenic variants and further sporadic human infections, with a continued risk of the virus acquiring human-to-human transmissibility.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3801098/" 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/PMC3801098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lam, Tommy Tsan-Yuk -- Wang, Jia -- Shen, Yongyi -- Zhou, Boping -- Duan, Lian -- Cheung, Chung-Lam -- Ma, Chi -- Lycett, Samantha J -- Leung, Connie Yin-Hung -- Chen, Xinchun -- Li, Lifeng -- Hong, Wenshan -- Chai, Yujuan -- Zhou, Linlin -- Liang, Huyi -- Ou, Zhihua -- Liu, Yongmei -- Farooqui, Amber -- Kelvin, David J -- Poon, Leo L M -- Smith, David K -- Pybus, Oliver G -- Leung, Gabriel M -- Shu, Yuelong -- Webster, Robert G -- Webby, Richard J -- Peiris, Joseph S M -- Rambaut, Andrew -- Zhu, Huachen -- Guan, Yi -- 092807/Wellcome Trust/United Kingdom -- 095831/Wellcome Trust/United Kingdom -- 260864/European Research Council/International -- BB/E009670/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- HHSN266200700005C/AI/NIAID NIH HHS/ -- HSN266200700005C/PHS HHS/ -- England -- Nature. 2013 Oct 10;502(7470):241-4. doi: 10.1038/nature12515.

Description: The spatial organization of the genome is intimately linked to its biological function, yet our understanding of higher order genomic structure is coarse, fragmented and incomplete. In the nucleus of eukaryotic cells, interphase chromosomes occupy distinct chromosome territories, and numerous models have been proposed for how chromosomes fold within chromosome territories. These models, however, provide only few mechanistic details about the relationship between higher order chromatin structure and genome function. Recent advances in genomic technologies have led to rapid advances in the study of three-dimensional genome organization. In particular, Hi-C has been introduced as a method for identifying higher order chromatin interactions genome wide. Here we investigate the three-dimensional organization of the human and mouse genomes in embryonic stem cells and terminally differentiated cell types at unprecedented resolution. We identify large, megabase-sized local chromatin interaction domains, which we term 'topological domains', as a pervasive structural feature of the genome organization. These domains correlate with regions of the genome that constrain the spread of heterochromatin. The domains are stable across different cell types and highly conserved across species, indicating that topological domains are an inherent property of mammalian genomes. Finally, we find that the boundaries of topological domains are enriched for the insulator binding protein CTCF, housekeeping genes, transfer RNAs and short interspersed element (SINE) retrotransposons, indicating that these factors may have a role in establishing the topological domain structure of the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3356448/" 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/PMC3356448/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dixon, Jesse R -- Selvaraj, Siddarth -- Yue, Feng -- Kim, Audrey -- Li, Yan -- Shen, Yin -- Hu, Ming -- Liu, Jun S -- Ren, Bing -- R01 HG003991/HG/NHGRI NIH HHS/ -- R01 HG003991-03/HG/NHGRI NIH HHS/ -- R01 HG003991-03S1/HG/NHGRI NIH HHS/ -- R01GH003991/GH/CGH CDC HHS/ -- England -- Nature. 2012 Apr 11;485(7398):376-80. doi: 10.1038/nature11082.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ludwig Institute for Cancer Research, 9500 Gilman Drive, La Jolla, California 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22495300" target="_blank"〉PubMed〈/a〉

Description: The laboratory mouse is the most widely used mammalian model organism in biomedical research. The 2.6 x 10(9) bases of the mouse genome possess a high degree of conservation with the human genome, so a thorough annotation of the mouse genome will be of significant value to understanding the function of the human genome. So far, most of the functional sequences in the mouse genome have yet to be found, and the cis-regulatory sequences in particular are still poorly annotated. Comparative genomics has been a powerful tool for the discovery of these sequences, but on its own it cannot resolve their temporal and spatial functions. Recently, ChIP-Seq has been developed to identify cis-regulatory elements in the genomes of several organisms including humans, Drosophila melanogaster and Caenorhabditis elegans. Here we apply the same experimental approach to a diverse set of 19 tissues and cell types in the mouse to produce a map of nearly 300,000 murine cis-regulatory sequences. The annotated sequences add up to 11% of the mouse genome, and include more than 70% of conserved non-coding sequences. We define tissue-specific enhancers and identify potential transcription factors regulating gene expression in each tissue or cell type. Finally, we show that much of the mouse genome is organized into domains of coordinately regulated enhancers and promoters. Our results provide a resource for the annotation of functional elements in the mammalian genome and for the study of mechanisms regulating tissue-specific gene expression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4041622/" 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/PMC4041622/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, Yin -- Yue, Feng -- McCleary, David F -- Ye, Zhen -- Edsall, Lee -- Kuan, Samantha -- Wagner, Ulrich -- Dixon, Jesse -- Lee, Leonard -- Lobanenkov, Victor V -- Ren, Bing -- R01HG003991/HG/NHGRI NIH HHS/ -- T32 GM007198/GM/NIGMS NIH HHS/ -- England -- Nature. 2012 Aug 2;488(7409):116-20. doi: 10.1038/nature11243.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ludwig Institute for Cancer Research, 9500 Gilman Drive, La Jolla, California 92093-0653, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22763441" target="_blank"〉PubMed〈/a〉

Description: The laboratory mouse shares the majority of its protein-coding genes with humans, making it the premier model organism in biomedical research, yet the two mammals differ in significant ways. To gain greater insights into both shared and species-specific transcriptional and cellular regulatory programs in the mouse, the Mouse ENCODE Consortium has mapped transcription, DNase I hypersensitivity, transcription factor binding, chromatin modifications and replication domains throughout the mouse genome in diverse cell and tissue types. By comparing with the human genome, we not only confirm substantial conservation in the newly annotated potential functional sequences, but also find a large degree of divergence of sequences involved in transcriptional regulation, chromatin state and higher order chromatin organization. Our results illuminate the wide range of evolutionary forces acting on genes and their regulatory regions, and provide a general resource for research into mammalian biology and mechanisms of human diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4266106/" 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/PMC4266106/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yue, Feng -- Cheng, Yong -- Breschi, Alessandra -- Vierstra, Jeff -- Wu, Weisheng -- Ryba, Tyrone -- Sandstrom, Richard -- Ma, Zhihai -- Davis, Carrie -- Pope, Benjamin D -- Shen, Yin -- Pervouchine, Dmitri D -- Djebali, Sarah -- Thurman, Robert E -- Kaul, Rajinder -- Rynes, Eric -- Kirilusha, Anthony -- Marinov, Georgi K -- Williams, Brian A -- Trout, Diane -- Amrhein, Henry -- Fisher-Aylor, Katherine -- Antoshechkin, Igor -- DeSalvo, Gilberto -- See, Lei-Hoon -- Fastuca, Meagan -- Drenkow, Jorg -- Zaleski, Chris -- Dobin, Alex -- Prieto, Pablo -- Lagarde, Julien -- Bussotti, Giovanni -- Tanzer, Andrea -- Denas, Olgert -- Li, Kanwei -- Bender, M A -- Zhang, Miaohua -- Byron, Rachel -- Groudine, Mark T -- McCleary, David -- Pham, Long -- Ye, Zhen -- Kuan, Samantha -- Edsall, Lee -- Wu, Yi-Chieh -- Rasmussen, Matthew D -- Bansal, Mukul S -- Kellis, Manolis -- Keller, Cheryl A -- Morrissey, Christapher S -- Mishra, Tejaswini -- Jain, Deepti -- Dogan, Nergiz -- Harris, Robert S -- Cayting, Philip -- Kawli, Trupti -- Boyle, Alan P -- Euskirchen, Ghia -- Kundaje, Anshul -- Lin, Shin -- Lin, Yiing -- Jansen, Camden -- Malladi, Venkat S -- Cline, Melissa S -- Erickson, Drew T -- Kirkup, Vanessa M -- Learned, Katrina -- Sloan, Cricket A -- Rosenbloom, Kate R -- Lacerda de Sousa, Beatriz -- Beal, Kathryn -- Pignatelli, Miguel -- Flicek, Paul -- Lian, Jin -- Kahveci, Tamer -- Lee, Dongwon -- Kent, W James -- Ramalho Santos, Miguel -- Herrero, Javier -- Notredame, Cedric -- Johnson, Audra -- Vong, Shinny -- Lee, Kristen -- Bates, Daniel -- Neri, Fidencio -- Diegel, Morgan -- Canfield, Theresa -- Sabo, Peter J -- Wilken, Matthew S -- Reh, Thomas A -- Giste, Erika -- Shafer, Anthony -- Kutyavin, Tanya -- Haugen, Eric -- Dunn, Douglas -- Reynolds, Alex P -- Neph, Shane -- Humbert, Richard -- Hansen, R Scott -- De Bruijn, Marella -- Selleri, Licia -- Rudensky, Alexander -- Josefowicz, Steven -- Samstein, Robert -- Eichler, Evan E -- Orkin, Stuart H -- Levasseur, Dana -- Papayannopoulou, Thalia -- Chang, Kai-Hsin -- Skoultchi, Arthur -- Gosh, Srikanta -- Disteche, Christine -- Treuting, Piper -- Wang, Yanli -- Weiss, Mitchell J -- Blobel, Gerd A -- Cao, Xiaoyi -- Zhong, Sheng -- Wang, Ting -- Good, Peter J -- Lowdon, Rebecca F -- Adams, Leslie B -- Zhou, Xiao-Qiao -- Pazin, Michael J -- Feingold, Elise A -- Wold, Barbara -- Taylor, James -- Mortazavi, Ali -- Weissman, Sherman M -- Stamatoyannopoulos, John A -- Snyder, Michael P -- Guigo, Roderic -- Gingeras, Thomas R -- Gilbert, David M -- Hardison, Ross C -- Beer, Michael A -- Ren, Bing -- Mouse ENCODE Consortium -- 095908/Wellcome Trust/United Kingdom -- 1U54HG007004/HG/NHGRI NIH HHS/ -- 3RC2HG005602/HG/NHGRI NIH HHS/ -- F31CA165863/CA/NCI NIH HHS/ -- F32HL110473/HL/NHLBI NIH HHS/ -- GM083337/GM/NIGMS NIH HHS/ -- GM085354/GM/NIGMS NIH HHS/ -- K99HL119617/HL/NHLBI NIH HHS/ -- P01 GM085354/GM/NIGMS NIH HHS/ -- P01 HL064190/HL/NHLBI NIH HHS/ -- P01 HL110860/HL/NHLBI NIH HHS/ -- P30 CA008748/CA/NCI NIH HHS/ -- P30 CA045508/CA/NCI NIH HHS/ -- R01 DK065806/DK/NIDDK NIH HHS/ -- R01 DK096266/DK/NIDDK NIH HHS/ -- R01 ES024992/ES/NIEHS NIH HHS/ -- R01 EY021482/EY/NEI NIH HHS/ -- R01 GM083337/GM/NIGMS NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG007175/HG/NHGRI NIH HHS/ -- R01 HG007348/HG/NHGRI NIH HHS/ -- R01 HG007354/HG/NHGRI NIH HHS/ -- R01DK065806/DK/NIDDK NIH HHS/ -- R01HD043997-09/HD/NICHD NIH HHS/ -- R01HG003991/HG/NHGRI NIH HHS/ -- R37 DK044746/DK/NIDDK NIH HHS/ -- R56 DK065806/DK/NIDDK NIH HHS/ -- RC2 HG005573/HG/NHGRI NIH HHS/ -- RC2HG005573/HG/NHGRI NIH HHS/ -- T32 GM081739/GM/NIGMS NIH HHS/ -- U01 HL099656/HL/NHLBI NIH HHS/ -- U01 HL099993/HL/NHLBI NIH HHS/ -- U54 HG006997/HG/NHGRI NIH HHS/ -- U54 HG006998/HG/NHGRI NIH HHS/ -- U54 HG007004/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Nov 20;515(7527):355-64. doi: 10.1038/nature13992.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Ludwig Institute for Cancer Research and University of California, San Diego School of Medicine, 9500 Gilman Drive, La Jolla, California 92093, USA.

Description: Since 2013 the occurrence of human infections by a novel avian H7N9 influenza virus in China has demonstrated the continuing threat posed by zoonotic pathogens. Although the first outbreak wave that was centred on eastern China was seemingly averted, human infections recurred in October 2013 (refs 3-7). It is unclear how the H7N9 virus re-emerged and how it will develop further; potentially it may become a long-term threat to public health. Here we show that H7N9 viruses have spread from eastern to southern China and become persistent in chickens, which has led to the establishment of multiple regionally distinct lineages with different reassortant genotypes. Repeated introductions of viruses from Zhejiang to other provinces and the presence of H7N9 viruses at live poultry markets have fuelled the recurrence of human infections. This rapid expansion of the geographical distribution and genetic diversity of the H7N9 viruses poses a direct challenge to current disease control systems. Our results also suggest that H7N9 viruses have become enzootic in China and may spread beyond the region, following the pattern previously observed with H5N1 and H9N2 influenza viruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lam, Tommy Tsan-Yuk -- Zhou, Boping -- Wang, Jia -- Chai, Yujuan -- Shen, Yongyi -- Chen, Xinchun -- Ma, Chi -- Hong, Wenshan -- Chen, Yin -- Zhang, Yanjun -- Duan, Lian -- Chen, Peiwen -- Jiang, Junfei -- Zhang, Yu -- Li, Lifeng -- Poon, Leo Lit Man -- Webby, Richard J -- Smith, David K -- Leung, Gabriel M -- Peiris, Joseph S M -- Holmes, Edward C -- Guan, Yi -- Zhu, Huachen -- HHSN272201400006C/PHS HHS/ -- England -- Nature. 2015 Jun 4;522(7554):102-5. doi: 10.1038/nature14348.

Description: Contusive spinal cord injury leads to a variety of disabilities owing to limited neuronal regeneration and functional plasticity. It is well established that an upregulation of glial-derived chondroitin sulphate proteoglycans (CSPGs) within the glial scar and perineuronal net creates a barrier to axonal regrowth and sprouting. Protein tyrosine phosphatase sigma (PTPsigma), along with its sister phosphatase leukocyte common antigen-related (LAR) and the nogo receptors 1 and 3 (NgR), have recently been identified as receptors for the inhibitory glycosylated side chains of CSPGs. Here we find in rats that PTPsigma has a critical role in converting growth cones into a dystrophic state by tightly stabilizing them within CSPG-rich substrates. We generated a membrane-permeable peptide mimetic of the PTPsigma wedge domain that binds to PTPsigma and relieves CSPG-mediated inhibition. Systemic delivery of this peptide over weeks restored substantial serotonergic innervation to the spinal cord below the level of injury and facilitated functional recovery of both locomotor and urinary systems. Our results add a new layer of understanding to the critical role of PTPsigma in mediating the growth-inhibited state of neurons due to CSPGs within the injured adult spinal cord.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4336236/" 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/PMC4336236/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lang, Bradley T -- Cregg, Jared M -- DePaul, Marc A -- Tran, Amanda P -- Xu, Kui -- Dyck, Scott M -- Madalena, Kathryn M -- Brown, Benjamin P -- Weng, Yi-Lan -- Li, Shuxin -- Karimi-Abdolrezaee, Soheila -- Busch, Sarah A -- Shen, Yingjie -- Silver, Jerry -- NS025713/NS/NINDS NIH HHS/ -- R01 EY024575/EY/NEI NIH HHS/ -- R01 NS025713/NS/NINDS NIH HHS/ -- R01 NS079432/NS/NINDS NIH HHS/ -- England -- Nature. 2015 Feb 19;518(7539):404-8. doi: 10.1038/nature13974.
