    Description: Axonal and synaptic degeneration is a hallmark of peripheral neuropathy, brain injury, and neurodegenerative disease. Axonal degeneration has been proposed to be mediated by an active autodestruction program, akin to apoptotic cell death; however, loss-of-function mutations capable of potently blocking axon self-destruction have not been described. Here, we show that loss of the Drosophila Toll receptor adaptor dSarm (sterile alpha/Armadillo/Toll-Interleukin receptor homology domain protein) cell-autonomously suppresses Wallerian degeneration for weeks after axotomy. Severed mouse Sarm1 null axons exhibit remarkable long-term survival both in vivo and in vitro, indicating that Sarm1 prodegenerative signaling is conserved in mammals. Our results provide direct evidence that axons actively promote their own destruction after injury and identify dSarm/Sarm1 as a member of an ancient axon death signaling pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Osterloh, Jeannette M -- Yang, Jing -- Rooney, Timothy M -- Fox, A Nicole -- Adalbert, Robert -- Powell, Eric H -- Sheehan, Amy E -- Avery, Michelle A -- Hackett, Rachel -- Logan, Mary A -- MacDonald, Jennifer M -- Ziegenfuss, Jennifer S -- Milde, Stefan -- Hou, Ying-Ju -- Nathan, Carl -- Ding, Aihao -- Brown, Robert H Jr -- Conforti, Laura -- Coleman, Michael -- Tessier-Lavigne, Marc -- Zuchner, Stephan -- Freeman, Marc R -- 5R01-NS050557-05/NS/NINDS NIH HHS/ -- AI030165/AI/NIAID NIH HHS/ -- R01NS059991/NS/NINDS NIH HHS/ -- R01NS072248/NS/NINDS NIH HHS/ -- RC2-NS070-342/NS/NINDS NIH HHS/ -- U54NS065712/NS/NINDS NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jul 27;337(6093):481-4. doi: 10.1126/science.1223899.

    Description: Medulloblastoma encompasses a collection of clinically and molecularly diverse tumour subtypes that together comprise the most common malignant childhood brain tumour. These tumours are thought to arise within the cerebellum, with approximately 25% originating from granule neuron precursor cells (GNPCs) after aberrant activation of the Sonic Hedgehog pathway (hereafter, SHH subtype). The pathological processes that drive heterogeneity among the other medulloblastoma subtypes are not known, hindering the development of much needed new therapies. Here we provide evidence that a discrete subtype of medulloblastoma that contains activating mutations in the WNT pathway effector CTNNB1 (hereafter, WNT subtype) arises outside the cerebellum from cells of the dorsal brainstem. We found that genes marking human WNT-subtype medulloblastomas are more frequently expressed in the lower rhombic lip (LRL) and embryonic dorsal brainstem than in the upper rhombic lip (URL) and developing cerebellum. Magnetic resonance imaging (MRI) and intra-operative reports showed that human WNT-subtype tumours infiltrate the dorsal brainstem, whereas SHH-subtype tumours are located within the cerebellar hemispheres. Activating mutations in Ctnnb1 had little impact on progenitor cell populations in the cerebellum, but caused the abnormal accumulation of cells on the embryonic dorsal brainstem which included aberrantly proliferating Zic1(+) precursor cells. These lesions persisted in all mutant adult mice; moreover, in 15% of cases in which Tp53 was concurrently deleted, they progressed to form medulloblastomas that recapitulated the anatomy and gene expression profiles of human WNT-subtype medulloblastoma. We provide the first evidence, to our knowledge, that subtypes of medulloblastoma have distinct cellular origins. Our data provide an explanation for the marked molecular and clinical differences between SHH- and WNT-subtype medulloblastomas and have profound implications for future research and treatment of this important childhood cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3059767/" 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/PMC3059767/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibson, Paul -- Tong, Yiai -- Robinson, Giles -- Thompson, Margaret C -- Currle, D Spencer -- Eden, Christopher -- Kranenburg, Tanya A -- Hogg, Twala -- Poppleton, Helen -- Martin, Julie -- Finkelstein, David -- Pounds, Stanley -- Weiss, Aaron -- Patay, Zoltan -- Scoggins, Matthew -- Ogg, Robert -- Pei, Yanxin -- Yang, Zeng-Jie -- Brun, Sonja -- Lee, Youngsoo -- Zindy, Frederique -- Lindsey, Janet C -- Taketo, Makoto M -- Boop, Frederick A -- Sanford, Robert A -- Gajjar, Amar -- Clifford, Steven C -- Roussel, Martine F -- McKinnon, Peter J -- Gutmann, David H -- Ellison, David W -- Wechsler-Reya, Robert -- Gilbertson, Richard J -- 01CA96832/CA/NCI NIH HHS/ -- P01 CA096832/CA/NCI NIH HHS/ -- P01 CA096832-06A18120/CA/NCI NIH HHS/ -- P01 CA096832-078120/CA/NCI NIH HHS/ -- P30CA021765/CA/NCI NIH HHS/ -- R01 CA129541/CA/NCI NIH HHS/ -- R01 CA129541-01/CA/NCI NIH HHS/ -- R01 CA129541-02/CA/NCI NIH HHS/ -- R01 CA129541-03/CA/NCI NIH HHS/ -- R01 CA129541-04/CA/NCI NIH HHS/ -- R01 CA129541-05/CA/NCI NIH HHS/ -- R01 NS037956/NS/NINDS NIH HHS/ -- R01 NS037956-13/NS/NINDS NIH HHS/ -- R01CA129541/CA/NCI NIH HHS/ -- England -- Nature. 2010 Dec 23;468(7327):1095-9. doi: 10.1038/nature09587.

    Description: The global shortening of messenger RNAs through alternative polyadenylation (APA) that occurs during enhanced cellular proliferation represents an important, yet poorly understood mechanism of regulated gene expression. The 3' untranslated region (UTR) truncation of growth-promoting mRNA transcripts that relieves intrinsic microRNA- and AU-rich-element-mediated repression has been observed to correlate with cellular transformation; however, the importance to tumorigenicity of RNA 3'-end-processing factors that potentially govern APA is unknown. Here we identify CFIm25 as a broad repressor of proximal poly(A) site usage that, when depleted, increases cell proliferation. Applying a regression model on standard RNA-sequencing data for novel APA events, we identified at least 1,450 genes with shortened 3' UTRs after CFIm25 knockdown, representing 11% of significantly expressed mRNAs in human cells. Marked increases in the expression of several known oncogenes, including cyclin D1, are observed as a consequence of CFIm25 depletion. Importantly, we identified a subset of CFIm25-regulated APA genes with shortened 3' UTRs in glioblastoma tumours that have reduced CFIm25 expression. Downregulation of CFIm25 expression in glioblastoma cells enhances their tumorigenic properties and increases tumour size, whereas CFIm25 overexpression reduces these properties and inhibits tumour growth. These findings identify a pivotal role of CFIm25 in governing APA and reveal a previously unknown connection between CFIm25 and glioblastoma tumorigenicity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4128630/" 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/PMC4128630/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masamha, Chioniso P -- Xia, Zheng -- Yang, Jingxuan -- Albrecht, Todd R -- Li, Min -- Shyu, Ann-Bin -- Li, Wei -- Wagner, Eric J -- CA166274/CA/NCI NIH HHS/ -- CA167752/CA/NCI NIH HHS/ -- GM046454/GM/NIGMS NIH HHS/ -- R01 GM046454/GM/NIGMS NIH HHS/ -- R01 HG007538/HG/NHGRI NIH HHS/ -- R01HG007538/HG/NHGRI NIH HHS/ -- England -- Nature. 2014 Jun 19;510(7505):412-6. doi: 10.1038/nature13261.

    Description: The role of long noncoding RNA (lncRNA) in adult hearts is unknown; also unclear is how lncRNA modulates nucleosome remodelling. An estimated 70% of mouse genes undergo antisense transcription, including myosin heavy chain 7 (Myh7), which encodes molecular motor proteins for heart contraction. Here we identify a cluster of lncRNA transcripts from Myh7 loci and demonstrate a new lncRNA-chromatin mechanism for heart failure. In mice, these transcripts, which we named myosin heavy-chain-associated RNA transcripts (Myheart, or Mhrt), are cardiac-specific and abundant in adult hearts. Pathological stress activates the Brg1-Hdac-Parp chromatin repressor complex to inhibit Mhrt transcription in the heart. Such stress-induced Mhrt repression is essential for cardiomyopathy to develop: restoring Mhrt to the pre-stress level protects the heart from hypertrophy and failure. Mhrt antagonizes the function of Brg1, a chromatin-remodelling factor that is activated by stress to trigger aberrant gene expression and cardiac myopathy. Mhrt prevents Brg1 from recognizing its genomic DNA targets, thus inhibiting chromatin targeting and gene regulation by Brg1. It does so by binding to the helicase domain of Brg1, a domain that is crucial for tethering Brg1 to chromatinized DNA targets. Brg1 helicase has dual nucleic-acid-binding specificities: it is capable of binding lncRNA (Mhrt) and chromatinized--but not naked--DNA. This dual-binding feature of helicase enables a competitive inhibition mechanism by which Mhrt sequesters Brg1 from its genomic DNA targets to prevent chromatin remodelling. A Mhrt-Brg1 feedback circuit is thus crucial for heart function. Human MHRT also originates from MYH7 loci and is repressed in various types of myopathic hearts, suggesting a conserved lncRNA mechanism in human cardiomyopathy. Our studies identify a cardioprotective lncRNA, define a new targeting mechanism for ATP-dependent chromatin-remodelling factors, and establish a new paradigm for lncRNA-chromatin interaction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4184960/" 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/PMC4184960/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Han, Pei -- Li, Wei -- Lin, Chiou-Hong -- Yang, Jin -- Shang, Ching -- Nurnberg, Sylvia T -- Jin, Kevin Kai -- Xu, Weihong -- Lin, Chieh-Yu -- Lin, Chien-Jung -- Xiong, Yiqin -- Chien, Huan-Chieh -- Zhou, Bin -- Ashley, Euan -- Bernstein, Daniel -- Chen, Peng-Sheng -- Chen, Huei-Sheng Vincent -- Quertermous, Thomas -- Chang, Ching-Pin -- HL105194/HL/NHLBI NIH HHS/ -- HL109512/HL/NHLBI NIH HHS/ -- HL111770/HL/NHLBI NIH HHS/ -- HL116997/HL/NHLBI NIH HHS/ -- HL118087/HL/NHLBI NIH HHS/ -- HL121197/HL/NHLBI NIH HHS/ -- HL71140/HL/NHLBI NIH HHS/ -- HL78931/HL/NHLBI NIH HHS/ -- R01 HL111770/HL/NHLBI NIH HHS/ -- R01 HL116997/HL/NHLBI NIH HHS/ -- R01 HL121197/HL/NHLBI NIH HHS/ -- England -- Nature. 2014 Oct 2;514(7520):102-6. doi: 10.1038/nature13596.

    Description: Inflammasomes are large cytoplasmic complexes that sense microbial infections/danger molecules and induce caspase-1 activation-dependent cytokine production and macrophage inflammatory death. The inflammasome assembled by the NOD-like receptor (NLR) protein NLRC4 responds to bacterial flagellin and a conserved type III secretion system (TTSS) rod component. How the NLRC4 inflammasome detects the two bacterial products and the molecular mechanism of NLRC4 inflammasome activation are not understood. Here we show that NAIP5, a BIR-domain NLR protein required for Legionella pneumophila replication in mouse macrophages, is a universal component of the flagellin-NLRC4 pathway. NAIP5 directly and specifically interacted with flagellin, which determined the inflammasome-stimulation activities of different bacterial flagellins. NAIP5 engagement by flagellin promoted a physical NAIP5-NLRC4 association, rendering full reconstitution of a flagellin-responsive NLRC4 inflammasome in non-macrophage cells. The related NAIP2 functioned analogously to NAIP5, serving as a specific inflammasome receptor for TTSS rod proteins such as Salmonella PrgJ and Burkholderia BsaK. Genetic analysis of Chromobacterium violaceum infection revealed that the TTSS needle protein CprI can stimulate NLRC4 inflammasome activation in human macrophages. Similarly, CprI is specifically recognized by human NAIP, the sole NAIP family member in human. The finding that NAIP proteins are inflammasome receptors for bacterial flagellin and TTSS apparatus components further predicts that the remaining NAIP family members may recognize other unidentified microbial products to activate NLRC4 inflammasome-mediated innate immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Yue -- Yang, Jieling -- Shi, Jianjin -- Gong, Yi-Nan -- Lu, Qiuhe -- Xu, Hao -- Liu, Liping -- Shao, Feng -- England -- Nature. 2011 Sep 14;477(7366):596-600. doi: 10.1038/nature10510.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Program in Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21918512" target="_blank"〉PubMed〈/a〉

    Description: Anaemia is a chief determinant of global ill health, contributing to cognitive impairment, growth retardation and impaired physical capacity. To understand further the genetic factors influencing red blood cells, we carried out a genome-wide association study of haemoglobin concentration and related parameters in up to 135,367 individuals. Here we identify 75 independent genetic loci associated with one or more red blood cell phenotypes at P 〈 10(-8), which together explain 4-9% of the phenotypic variance per trait. Using expression quantitative trait loci and bioinformatic strategies, we identify 121 candidate genes enriched in functions relevant to red blood cell biology. The candidate genes are expressed preferentially in red blood cell precursors, and 43 have haematopoietic phenotypes in Mus musculus or Drosophila melanogaster. Through open-chromatin and coding-variant analyses we identify potential causal genetic variants at 41 loci. Our findings provide extensive new insights into genetic mechanisms and biological pathways controlling red blood cell formation and function.〈br /〉〈br /〉〈a

    Description: Cytosolic inflammasome complexes mediated by a pattern recognition receptor (PRR) defend against pathogen infection by activating caspase 1. Pyrin, a candidate PRR, can bind to the inflammasome adaptor ASC to form a caspase 1-activating complex. Mutations in the Pyrin-encoding gene, MEFV, cause a human autoinflammatory disease known as familial Mediterranean fever. Despite important roles in immunity and disease, the physiological function of Pyrin remains unknown. Here we show that Pyrin mediates caspase 1 inflammasome activation in response to Rho-glucosylation activity of cytotoxin TcdB, a major virulence factor of Clostridium difficile, which causes most cases of nosocomial diarrhoea. The glucosyltransferase-inactive TcdB mutant loses the inflammasome-stimulating activity. Other Rho-inactivating toxins, including FIC-domain adenylyltransferases (Vibrio parahaemolyticus VopS and Histophilus somni IbpA) and Clostridium botulinum ADP-ribosylating C3 toxin, can also biochemically activate the Pyrin inflammasome in their enzymatic activity-dependent manner. These toxins all target the Rho subfamily and modify a switch-I residue. We further demonstrate that Burkholderia cenocepacia inactivates RHOA by deamidating Asn 41, also in the switch-I region, and thereby triggers Pyrin inflammasome activation, both of which require the bacterial type VI secretion system (T6SS). Loss of the Pyrin inflammasome causes elevated intra-macrophage growth of B. cenocepacia and diminished lung inflammation in mice. Thus, Pyrin functions to sense pathogen modification and inactivation of Rho GTPases, representing a new paradigm in mammalian innate immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Hao -- Yang, Jieling -- Gao, Wenqing -- Li, Lin -- Li, Peng -- Zhang, Li -- Gong, Yi-Nan -- Peng, Xiaolan -- Xi, Jianzhong Jeff -- Chen, She -- Wang, Fengchao -- Shao, Feng -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Sep 11;513(7517):237-41. doi: 10.1038/nature13449.

    Description: A major challenge in human genetics is to devise a systematic strategy to integrate disease-associated variants with diverse genomic and biological data sets to provide insight into disease pathogenesis and guide drug discovery for complex traits such as rheumatoid arthritis (RA). Here we performed a genome-wide association study meta-analysis in a total of 〉100,000 subjects of European and Asian ancestries (29,880 RA cases and 73,758 controls), by evaluating approximately 10 million single-nucleotide polymorphisms. We discovered 42 novel RA risk loci at a genome-wide level of significance, bringing the total to 101 (refs 2 - 4). We devised an in silico pipeline using established bioinformatics methods based on functional annotation, cis-acting expression quantitative trait loci and pathway analyses--as well as novel methods based on genetic overlap with human primary immunodeficiency, haematological cancer somatic mutations and knockout mouse phenotypes--to identify 98 biological candidate genes at these 101 risk loci. We demonstrate that these genes are the targets of approved therapies for RA, and further suggest that drugs approved for other indications may be repurposed for the treatment of RA. Together, this comprehensive genetic study sheds light on fundamental genes, pathways and cell types that contribute to RA pathogenesis, and provides empirical evidence that the genetics of RA can provide important information for drug discovery.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3944098/" 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/PMC3944098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okada, Yukinori -- Wu, Di -- Trynka, Gosia -- Raj, Towfique -- Terao, Chikashi -- Ikari, Katsunori -- Kochi, Yuta -- Ohmura, Koichiro -- Suzuki, Akari -- Yoshida, Shinji -- Graham, Robert R -- Manoharan, Arun -- Ortmann, Ward -- Bhangale, Tushar -- Denny, Joshua C -- Carroll, Robert J -- Eyler, Anne E -- Greenberg, Jeffrey D -- Kremer, Joel M -- Pappas, Dimitrios A -- Jiang, Lei -- Yin, Jian -- Ye, Lingying -- Su, Ding-Feng -- Yang, Jian -- Xie, Gang -- Keystone, Ed -- Westra, Harm-Jan -- Esko, Tonu -- Metspalu, Andres -- Zhou, Xuezhong -- Gupta, Namrata -- Mirel, Daniel -- Stahl, Eli A -- Diogo, Dorothee -- Cui, Jing -- Liao, Katherine -- Guo, Michael H -- Myouzen, Keiko -- Kawaguchi, Takahisa -- Coenen, Marieke J H -- van Riel, Piet L C M -- van de Laar, Mart A F J -- Guchelaar, Henk-Jan -- Huizinga, Tom W J -- Dieude, Philippe -- Mariette, Xavier -- Bridges, S Louis Jr -- Zhernakova, Alexandra -- Toes, Rene E M -- Tak, Paul P -- Miceli-Richard, Corinne -- Bang, So-Young -- Lee, Hye-Soon -- Martin, Javier -- Gonzalez-Gay, Miguel A -- Rodriguez-Rodriguez, Luis -- Rantapaa-Dahlqvist, Solbritt -- Arlestig, Lisbeth -- Choi, Hyon K -- Kamatani, Yoichiro -- Galan, Pilar -- Lathrop, Mark -- RACI consortium -- GARNET consortium -- Eyre, Steve -- Bowes, John -- Barton, Anne -- de Vries, Niek -- Moreland, Larry W -- Criswell, Lindsey A -- Karlson, Elizabeth W -- Taniguchi, Atsuo -- Yamada, Ryo -- Kubo, Michiaki -- Liu, Jun S -- Bae, Sang-Cheol -- Worthington, Jane -- Padyukov, Leonid -- Klareskog, Lars -- Gregersen, Peter K -- Raychaudhuri, Soumya -- Stranger, Barbara E -- De Jager, Philip L -- Franke, Lude -- Visscher, Peter M -- Brown, Matthew A -- Yamanaka, Hisashi -- Mimori, Tsuneyo -- Takahashi, Atsushi -- Xu, Huji -- Behrens, Timothy W -- Siminovitch, Katherine A -- Momohara, Shigeki -- Matsuda, Fumihiko -- Yamamoto, Kazuhiko -- Plenge, Robert M -- 20385/Arthritis Research UK/United Kingdom -- 79321/Canadian Institutes of Health Research/Canada -- K08-KAR055688A/PHS HHS/ -- K24 AR052403/AR/NIAMS NIH HHS/ -- P60 AR047785/AR/NIAMS NIH HHS/ -- R01 AR056768/AR/NIAMS NIH HHS/ -- R01 AR057108/AR/NIAMS NIH HHS/ -- R01 AR059648/AR/NIAMS NIH HHS/ -- R01 AR063759/AR/NIAMS NIH HHS/ -- R01-AR056291/AR/NIAMS NIH HHS/ -- R01-AR056768/AR/NIAMS NIH HHS/ -- R01-AR057108/AR/NIAMS NIH HHS/ -- R01-AR059648/AR/NIAMS NIH HHS/ -- R01-AR065944/AR/NIAMS NIH HHS/ -- R01AR063759-01A1/AR/NIAMS NIH HHS/ -- R21 AR056042/AR/NIAMS NIH HHS/ -- T15 LM007450/LM/NLM NIH HHS/ -- U01 GM092691/GM/NIGMS NIH HHS/ -- U01-GM092691/GM/NIGMS NIH HHS/ -- U19 HL065962/HL/NHLBI NIH HHS/ -- England -- Nature. 2014 Feb 20;506(7488):376-81. doi: 10.1038/nature12873.

    Description: Cardiac hypertrophy and failure are characterized by transcriptional reprogramming of gene expression. Adult cardiomyocytes in mice primarily express alpha-myosin heavy chain (alpha-MHC, also known as Myh6), whereas embryonic cardiomyocytes express beta-MHC (also known as Myh7). Cardiac stress triggers adult hearts to undergo hypertrophy and a shift from alpha-MHC to fetal beta-MHC expression. Here we show that Brg1, a chromatin-remodelling protein, has a critical role in regulating cardiac growth, differentiation and gene expression. In embryos, Brg1 promotes myocyte proliferation by maintaining Bmp10 and suppressing p57(kip2) expression. It preserves fetal cardiac differentiation by interacting with histone deacetylase (HDAC) and poly (ADP ribose) polymerase (PARP) to repress alpha-MHC and activate beta-MHC. In adults, Brg1 (also known as Smarca4) is turned off in cardiomyocytes. It is reactivated by cardiac stresses and forms a complex with its embryonic partners, HDAC and PARP, to induce a pathological alpha-MHC to beta-MHC shift. Preventing Brg1 re-expression decreases hypertrophy and reverses this MHC switch. BRG1 is activated in certain patients with hypertrophic cardiomyopathy, its level correlating with disease severity and MHC changes. Our studies show that Brg1 maintains cardiomyocytes in an embryonic state, and demonstrate an epigenetic mechanism by which three classes of chromatin-modifying factors-Brg1, HDAC and PARP-cooperate to control developmental and pathological gene expression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2898892/" 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/PMC2898892/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hang, Calvin T -- Yang, Jin -- Han, Pei -- Cheng, Hsiu-Ling -- Shang, Ching -- Ashley, Euan -- Zhou, Bin -- Chang, Ching-Pin -- R01 HL085345/HL/NHLBI NIH HHS/ -- R01 HL085345-03S1/HL/NHLBI NIH HHS/ -- R01 HL085345-04/HL/NHLBI NIH HHS/ -- T32 CA009302/CA/NCI NIH HHS/ -- England -- Nature. 2010 Jul 1;466(7302):62-7. doi: 10.1038/nature09130.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cardiovascular Medicine, Department of Medicine, Stanford University School of Medicine, Stanford, California 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20596014" target="_blank"〉PubMed〈/a〉

    Description: Myocardial cell death is initiated by excessive mitochondrial Ca(2+) entry causing Ca(2+) overload, mitochondrial permeability transition pore (mPTP) opening and dissipation of the mitochondrial inner membrane potential (DeltaPsim). However, the signalling pathways that control mitochondrial Ca(2+) entry through the inner membrane mitochondrial Ca(2+) uniporter (MCU) are not known. The multifunctional Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) is activated in ischaemia reperfusion, myocardial infarction and neurohumoral injury, common causes of myocardial death and heart failure; these findings suggest that CaMKII could couple disease stress to mitochondrial injury. Here we show that CaMKII promotes mPTP opening and myocardial death by increasing MCU current (I(MCU)). Mitochondrial-targeted CaMKII inhibitory protein or cyclosporin A, an mPTP antagonist with clinical efficacy in ischaemia reperfusion injury, equivalently prevent mPTP opening, DeltaPsim deterioration and diminish mitochondrial disruption and programmed cell death in response to ischaemia reperfusion injury. Mice with myocardial and mitochondrial-targeted CaMKII inhibition have reduced I(MCU) and are resistant to ischaemia reperfusion injury, myocardial infarction and neurohumoral injury, suggesting that pathological actions of CaMKII are substantially mediated by increasing I(MCU). Our findings identify CaMKII activity as a central mechanism for mitochondrial Ca(2+) entry in myocardial cell death, and indicate that mitochondrial-targeted CaMKII inhibition could prevent or reduce myocardial death and heart failure in response to common experimental forms of pathophysiological stress.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3471377/" 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/PMC3471377/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Joiner, Mei-Ling A -- Koval, Olha M -- Li, Jingdong -- He, B Julie -- Allamargot, Chantal -- Gao, Zhan -- Luczak, Elizabeth D -- Hall, Duane D -- Fink, Brian D -- Chen, Biyi -- Yang, Jinying -- Moore, Steven A -- Scholz, Thomas D -- Strack, Stefan -- Mohler, Peter J -- Sivitz, William I -- Song, Long-Sheng -- Anderson, Mark E -- R01 HL062494/HL/NHLBI NIH HHS/ -- R01 HL070250/HL/NHLBI NIH HHS/ -- R01 HL079031/HL/NHLBI NIH HHS/ -- R01 HL083422/HL/NHLBI NIH HHS/ -- R01 HL084583/HL/NHLBI NIH HHS/ -- R01 HL090905/HL/NHLBI NIH HHS/ -- R01 HL113001/HL/NHLBI NIH HHS/ -- R01 HL62494/HL/NHLBI NIH HHS/ -- R01 HL70250/HL/NHLBI NIH HHS/ -- R56 NS056244/NS/NINDS NIH HHS/ -- England -- Nature. 2012 Nov 8;491(7423):269-73. doi: 10.1038/nature11444.
