    Description: Follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL) are the two most common non-Hodgkin lymphomas (NHLs). Here we sequenced tumour and matched normal DNA from 13 DLBCL cases and one FL case to identify genes with mutations in B-cell NHL. We analysed RNA-seq data from these and another 113 NHLs to identify genes with candidate mutations, and then re-sequenced tumour and matched normal DNA from these cases to confirm 109 genes with multiple somatic mutations. Genes with roles in histone modification were frequent targets of somatic mutation. For example, 32% of DLBCL and 89% of FL cases had somatic mutations in MLL2, which encodes a histone methyltransferase, and 11.4% and 13.4% of DLBCL and FL cases, respectively, had mutations in MEF2B, a calcium-regulated gene that cooperates with CREBBP and EP300 in acetylating histones. Our analysis suggests a previously unappreciated disruption of chromatin biology in lymphomagenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3210554/" 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/PMC3210554/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morin, Ryan D -- Mendez-Lago, Maria -- Mungall, Andrew J -- Goya, Rodrigo -- Mungall, Karen L -- Corbett, Richard D -- Johnson, Nathalie A -- Severson, Tesa M -- Chiu, Readman -- Field, Matthew -- Jackman, Shaun -- Krzywinski, Martin -- Scott, David W -- Trinh, Diane L -- Tamura-Wells, Jessica -- Li, Sa -- Firme, Marlo R -- Rogic, Sanja -- Griffith, Malachi -- Chan, Susanna -- Yakovenko, Oleksandr -- Meyer, Irmtraud M -- Zhao, Eric Y -- Smailus, Duane -- Moksa, Michelle -- Chittaranjan, Suganthi -- Rimsza, Lisa -- Brooks-Wilson, Angela -- Spinelli, John J -- Ben-Neriah, Susana -- Meissner, Barbara -- Woolcock, Bruce -- Boyle, Merrill -- McDonald, Helen -- Tam, Angela -- Zhao, Yongjun -- Delaney, Allen -- Zeng, Thomas -- Tse, Kane -- Butterfield, Yaron -- Birol, Inanc -- Holt, Rob -- Schein, Jacqueline -- Horsman, Douglas E -- Moore, Richard -- Jones, Steven J M -- Connors, Joseph M -- Hirst, Martin -- Gascoyne, Randy D -- Marra, Marco A -- 1U01CA114778/CA/NCI NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- P50CA130805-01/CA/NCI NIH HHS/ -- TGT-53912/Canadian Institutes of Health Research/Canada -- U24 CA143866/CA/NCI NIH HHS/ -- U24 CA143866-01/CA/NCI NIH HHS/ -- U24 CA143866-02/CA/NCI NIH HHS/ -- U24 CA143866-03/CA/NCI NIH HHS/ -- England -- Nature. 2011 Jul 27;476(7360):298-303. doi: 10.1038/nature10351.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Canada's Michael Smith Genome Sciences Centre, BC Cancer Agency, Vancouver, British Columbia V5Z 1L3, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21796119" target="_blank"〉PubMed〈/a〉

    Description: DNA methylation is a heritable epigenetic modification involved in gene silencing, imprinting, and the suppression of retrotransposons. Global DNA demethylation occurs in the early embryo and the germ line, and may be mediated by Tet (ten eleven translocation) enzymes, which convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). Tet enzymes have been studied extensively in mouse embryonic stem (ES) cells, which are generally cultured in the absence of vitamin C, a potential cofactor for Fe(II) 2-oxoglutarate dioxygenase enzymes such as Tet enzymes. Here we report that addition of vitamin C to mouse ES cells promotes Tet activity, leading to a rapid and global increase in 5hmC. This is followed by DNA demethylation of many gene promoters and upregulation of demethylated germline genes. Tet1 binding is enriched near the transcription start site of genes affected by vitamin C treatment. Importantly, vitamin C, but not other antioxidants, enhances the activity of recombinant Tet1 in a biochemical assay, and the vitamin-C-induced changes in 5hmC and 5mC are entirely suppressed in Tet1 and Tet2 double knockout ES cells. Vitamin C has a stronger effect on regions that gain methylation in cultured ES cells compared to blastocysts, and in vivo are methylated only after implantation. In contrast, imprinted regions and intracisternal A particle retroelements, which are resistant to demethylation in the early embryo, are resistant to vitamin-C-induced DNA demethylation. Collectively, the results of this study establish vitamin C as a direct regulator of Tet activity and DNA methylation fidelity in ES cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3893718/" 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/PMC3893718/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blaschke, Kathryn -- Ebata, Kevin T -- Karimi, Mohammad M -- Zepeda-Martinez, Jorge A -- Goyal, Preeti -- Mahapatra, Sahasransu -- Tam, Angela -- Laird, Diana J -- Hirst, Martin -- Rao, Anjana -- Lorincz, Matthew C -- Ramalho-Santos, Miguel -- 92093/Canadian Institutes of Health Research/Canada -- CA151535/CA/NCI NIH HHS/ -- DP2 OD007420/OD/NIH HHS/ -- DP2OD004698/OD/NIH HHS/ -- HD065812/HD/NICHD NIH HHS/ -- P30 DK063720/DK/NIDDK NIH HHS/ -- R01 AI044432/AI/NIAID NIH HHS/ -- R01 CA151535/CA/NCI NIH HHS/ -- R01 HD065812/HD/NICHD NIH HHS/ -- R01 OD012204/OD/NIH HHS/ -- England -- Nature. 2013 Aug 8;500(7461):222-6. doi: 10.1038/nature12362.
