    Description: Medulloblastoma is an aggressively growing tumour, arising in the cerebellum or medulla/brain stem. It is the most common malignant brain tumour in children, and shows tremendous biological and clinical heterogeneity. Despite recent treatment advances, approximately 40% of children experience tumour recurrence, and 30% will die from their disease. Those who survive often have a significantly reduced quality of life. Four tumour subgroups with distinct clinical, biological and genetic profiles are currently identified. WNT tumours, showing activated wingless pathway signalling, carry a favourable prognosis under current treatment regimens. SHH tumours show hedgehog pathway activation, and have an intermediate prognosis. Group 3 and 4 tumours are molecularly less well characterized, and also present the greatest clinical challenges. The full repertoire of genetic events driving this distinction, however, remains unclear. Here we describe an integrative deep-sequencing analysis of 125 tumour-normal pairs, conducted as part of the International Cancer Genome Consortium (ICGC) PedBrain Tumor Project. Tetraploidy was identified as a frequent early event in Group 3 and 4 tumours, and a positive correlation between patient age and mutation rate was observed. Several recurrent mutations were identified, both in known medulloblastoma-related genes (CTNNB1, PTCH1, MLL2, SMARCA4) and in genes not previously linked to this tumour (DDX3X, CTDNEP1, KDM6A, TBR1), often in subgroup-specific patterns. RNA sequencing confirmed these alterations, and revealed the expression of what are, to our knowledge, the first medulloblastoma fusion genes identified. Chromatin modifiers were frequently altered across all subgroups. These findings enhance our understanding of the genomic complexity and heterogeneity underlying medulloblastoma, and provide several potential targets for new therapeutics, especially for Group 3 and 4 patients.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662966/" 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/PMC3662966/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, David T W -- Jager, Natalie -- Kool, Marcel -- Zichner, Thomas -- Hutter, Barbara -- Sultan, Marc -- Cho, Yoon-Jae -- Pugh, Trevor J -- Hovestadt, Volker -- Stutz, Adrian M -- Rausch, Tobias -- Warnatz, Hans-Jorg -- Ryzhova, Marina -- Bender, Sebastian -- Sturm, Dominik -- Pleier, Sabrina -- Cin, Huriye -- Pfaff, Elke -- Sieber, Laura -- Wittmann, Andrea -- Remke, Marc -- Witt, Hendrik -- Hutter, Sonja -- Tzaridis, Theophilos -- Weischenfeldt, Joachim -- Raeder, Benjamin -- Avci, Meryem -- Amstislavskiy, Vyacheslav -- Zapatka, Marc -- Weber, Ursula D -- Wang, Qi -- Lasitschka, Barbel -- Bartholomae, Cynthia C -- Schmidt, Manfred -- von Kalle, Christof -- Ast, Volker -- Lawerenz, Chris -- Eils, Jurgen -- Kabbe, Rolf -- Benes, Vladimir -- van Sluis, Peter -- Koster, Jan -- Volckmann, Richard -- Shih, David -- Betts, Matthew J -- Russell, Robert B -- Coco, Simona -- Tonini, Gian Paolo -- Schuller, Ulrich -- Hans, Volkmar -- Graf, Norbert -- Kim, Yoo-Jin -- Monoranu, Camelia -- Roggendorf, Wolfgang -- Unterberg, Andreas -- Herold-Mende, Christel -- Milde, Till -- Kulozik, Andreas E -- von Deimling, Andreas -- Witt, Olaf -- Maass, Eberhard -- Rossler, Jochen -- Ebinger, Martin -- Schuhmann, Martin U -- Fruhwald, Michael C -- Hasselblatt, Martin -- Jabado, Nada -- Rutkowski, Stefan -- von Bueren, Andre O -- Williamson, Dan -- Clifford, Steven C -- McCabe, Martin G -- Collins, V Peter -- Wolf, Stephan -- Wiemann, Stefan -- Lehrach, Hans -- Brors, Benedikt -- Scheurlen, Wolfram -- Felsberg, Jorg -- Reifenberger, Guido -- Northcott, Paul A -- Taylor, Michael D -- Meyerson, Matthew -- Pomeroy, Scott L -- Yaspo, Marie-Laure -- Korbel, Jan O -- Korshunov, Andrey -- Eils, Roland -- Pfister, Stefan M -- Lichter, Peter -- P30 HD018655/HD/NICHD NIH HHS/ -- R01 CA109467/CA/NCI NIH HHS/ -- England -- Nature. 2012 Aug 2;488(7409):100-5. doi: 10.1038/nature11284.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Pediatric Neurooncology, German Cancer Research Center (DKFZ), Im Neuenheimer Feld 280, Heidelberg 69120, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22832583" target="_blank"〉PubMed〈/a〉

    Description: Epigenetic alterations, that is, disruption of DNA methylation and chromatin architecture, are now acknowledged as a universal feature of tumorigenesis. Medulloblastoma, a clinically challenging, malignant childhood brain tumour, is no exception. Despite much progress from recent genomics studies, with recurrent changes identified in each of the four distinct tumour subgroups (WNT-pathway-activated, SHH-pathway-activated, and the less-well-characterized Group 3 and Group 4), many cases still lack an obvious genetic driver. Here we present whole-genome bisulphite-sequencing data from thirty-four human and five murine tumours plus eight human and three murine normal controls, augmented with matched whole-genome, RNA and chromatin immunoprecipitation sequencing data. This comprehensive data set allowed us to decipher several features underlying the interplay between the genome, epigenome and transcriptome, and its effects on medulloblastoma pathophysiology. Most notable were highly prevalent regions of hypomethylation correlating with increased gene expression, extending tens of kilobases downstream of transcription start sites. Focal regions of low methylation linked to transcription-factor-binding sites shed light on differential transcriptional networks between subgroups, whereas increased methylation due to re-normalization of repressed chromatin in DNA methylation valleys was positively correlated with gene expression. Large, partially methylated domains affecting up to one-third of the genome showed increased mutation rates and gene silencing in a subgroup-specific fashion. Epigenetic alterations also affected novel medulloblastoma candidate genes (for example, LIN28B), resulting in alternative promoter usage and/or differential messenger RNA/microRNA expression. Analysis of mouse medulloblastoma and precursor-cell methylation demonstrated a somatic origin for many alterations. Our data provide insights into the epigenetic regulation of transcription and genome organization in medulloblastoma pathogenesis, which are probably also of importance in a wider developmental and disease context.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hovestadt, Volker -- Jones, David T W -- Picelli, Simone -- Wang, Wei -- Kool, Marcel -- Northcott, Paul A -- Sultan, Marc -- Stachurski, Katharina -- Ryzhova, Marina -- Warnatz, Hans-Jorg -- Ralser, Meryem -- Brun, Sonja -- Bunt, Jens -- Jager, Natalie -- Kleinheinz, Kortine -- Erkek, Serap -- Weber, Ursula D -- Bartholomae, Cynthia C -- von Kalle, Christof -- Lawerenz, Chris -- Eils, Jurgen -- Koster, Jan -- Versteeg, Rogier -- Milde, Till -- Witt, Olaf -- Schmidt, Sabine -- Wolf, Stephan -- Pietsch, Torsten -- Rutkowski, Stefan -- Scheurlen, Wolfram -- Taylor, Michael D -- Brors, Benedikt -- Felsberg, Jorg -- Reifenberger, Guido -- Borkhardt, Arndt -- Lehrach, Hans -- Wechsler-Reya, Robert J -- Eils, Roland -- Yaspo, Marie-Laure -- Landgraf, Pablo -- Korshunov, Andrey -- Zapatka, Marc -- Radlwimmer, Bernhard -- Pfister, Stefan M -- Lichter, Peter -- England -- Nature. 2014 Jun 26;510(7506):537-41. doi: 10.1038/nature13268.

    Description: Mutations in the IDH1 and IDH2 genes encoding isocitrate dehydrogenases are frequently found in human glioblastomas and cytogenetically normal acute myeloid leukaemias (AML). These alterations are gain-of-function mutations in that they drive the synthesis of the 'oncometabolite' R-2-hydroxyglutarate (2HG). It remains unclear how IDH1 and IDH2 mutations modify myeloid cell development and promote leukaemogenesis. Here we report the characterization of conditional knock-in (KI) mice in which the most common IDH1 mutation, IDH1(R132H), is inserted into the endogenous murine Idh1 locus and is expressed in all haematopoietic cells (Vav-KI mice) or specifically in cells of the myeloid lineage (LysM-KI mice). These mutants show increased numbers of early haematopoietic progenitors and develop splenomegaly and anaemia with extramedullary haematopoiesis, suggesting a dysfunctional bone marrow niche. Furthermore, LysM-KI cells have hypermethylated histones and changes to DNA methylation similar to those observed in human IDH1- or IDH2-mutant AML. To our knowledge, our study is the first to describe the generation and characterization of conditional IDH1(R132H)-KI mice, and also the first report to demonstrate the induction of a leukaemic DNA methylation signature in a mouse model. Our report thus sheds light on the mechanistic links between IDH1 mutation and human AML.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4005896/" 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/PMC4005896/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sasaki, Masato -- Knobbe, Christiane B -- Munger, Joshua C -- Lind, Evan F -- Brenner, Dirk -- Brustle, Anne -- Harris, Isaac S -- Holmes, Roxanne -- Wakeham, Andrew -- Haight, Jillian -- You-Ten, Annick -- Li, Wanda Y -- Schalm, Stefanie -- Su, Shinsan M -- Virtanen, Carl -- Reifenberger, Guido -- Ohashi, Pamela S -- Barber, Dwayne L -- Figueroa, Maria E -- Melnick, Ari -- Zuniga-Pflucker, Juan-Carlos -- Mak, Tak W -- R01 AI081773/AI/NIAID NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2012 Aug 30;488(7413):656-9. doi: 10.1038/nature11323.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Campbell Family Institute for Breast Cancer Research, Ontario Cancer Institute, University Health Network, Toronto, Ontario M5G 2C1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22763442" target="_blank"〉PubMed〈/a〉

    Description: Glioblastoma multiforme (GBM) is a lethal brain tumour in adults and children. However, DNA copy number and gene expression signatures indicate differences between adult and paediatric cases. To explore the genetic events underlying this distinction, we sequenced the exomes of 48 paediatric GBM samples. Somatic mutations in the H3.3-ATRX-DAXX chromatin remodelling pathway were identified in 44% of tumours (21/48). Recurrent mutations in H3F3A, which encodes the replication-independent histone 3 variant H3.3, were observed in 31% of tumours, and led to amino acid substitutions at two critical positions within the histone tail (K27M, G34R/G34V) involved in key regulatory post-translational modifications. Mutations in ATRX (alpha-thalassaemia/mental retardation syndrome X-linked) and DAXX (death-domain associated protein), encoding two subunits of a chromatin remodelling complex required for H3.3 incorporation at pericentric heterochromatin and telomeres, were identified in 31% of samples overall, and in 100% of tumours harbouring a G34R or G34V H3.3 mutation. Somatic TP53 mutations were identified in 54% of all cases, and in 86% of samples with H3F3A and/or ATRX mutations. Screening of a large cohort of gliomas of various grades and histologies (n = 784) showed H3F3A mutations to be specific to GBM and highly prevalent in children and young adults. Furthermore, the presence of H3F3A/ATRX-DAXX/TP53 mutations was strongly associated with alternative lengthening of telomeres and specific gene expression profiles. This is, to our knowledge, the first report to highlight recurrent mutations in a regulatory histone in humans, and our data suggest that defects of the chromatin architecture underlie paediatric and young adult GBM pathogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwartzentruber, Jeremy -- Korshunov, Andrey -- Liu, Xiao-Yang -- Jones, David T W -- Pfaff, Elke -- Jacob, Karine -- Sturm, Dominik -- Fontebasso, Adam M -- Quang, Dong-Anh Khuong -- Tonjes, Martje -- Hovestadt, Volker -- Albrecht, Steffen -- Kool, Marcel -- Nantel, Andre -- Konermann, Carolin -- Lindroth, Anders -- Jager, Natalie -- Rausch, Tobias -- Ryzhova, Marina -- Korbel, Jan O -- Hielscher, Thomas -- Hauser, Peter -- Garami, Miklos -- Klekner, Almos -- Bognar, Laszlo -- Ebinger, Martin -- Schuhmann, Martin U -- Scheurlen, Wolfram -- Pekrun, Arnulf -- Fruhwald, Michael C -- Roggendorf, Wolfgang -- Kramm, Christoph -- Durken, Matthias -- Atkinson, Jeffrey -- Lepage, Pierre -- Montpetit, Alexandre -- Zakrzewska, Magdalena -- Zakrzewski, Krzystof -- Liberski, Pawel P -- Dong, Zhifeng -- Siegel, Peter -- Kulozik, Andreas E -- Zapatka, Marc -- Guha, Abhijit -- Malkin, David -- Felsberg, Jorg -- Reifenberger, Guido -- von Deimling, Andreas -- Ichimura, Koichi -- Collins, V Peter -- Witt, Hendrik -- Milde, Till -- Witt, Olaf -- Zhang, Cindy -- Castelo-Branco, Pedro -- Lichter, Peter -- Faury, Damien -- Tabori, Uri -- Plass, Christoph -- Majewski, Jacek -- Pfister, Stefan M -- Jabado, Nada -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2012 Jan 29;482(7384):226-31. doi: 10.1038/nature10833.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McGill University and Genome Quebec Innovation Centre, Montreal, Quebec H3A 1A4, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22286061" target="_blank"〉PubMed〈/a〉

    Description: Medulloblastoma is a highly malignant paediatric brain tumour currently treated with a combination of surgery, radiation and chemotherapy, posing a considerable burden of toxicity to the developing child. Genomics has illuminated the extensive intertumoral heterogeneity of medulloblastoma, identifying four distinct molecular subgroups. Group 3 and group 4 subgroup medulloblastomas account for most paediatric cases; yet, oncogenic drivers for these subtypes remain largely unidentified. Here we describe a series of prevalent, highly disparate genomic structural variants, restricted to groups 3 and 4, resulting in specific and mutually exclusive activation of the growth factor independent 1 family proto-oncogenes, GFI1 and GFI1B. Somatic structural variants juxtapose GFI1 or GFI1B coding sequences proximal to active enhancer elements, including super-enhancers, instigating oncogenic activity. Our results, supported by evidence from mouse models, identify GFI1 and GFI1B as prominent medulloblastoma oncogenes and implicate 'enhancer hijacking' as an efficient mechanism driving oncogene activation in a childhood cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4201514/" 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/PMC4201514/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Northcott, Paul A -- Lee, Catherine -- Zichner, Thomas -- Stutz, Adrian M -- Erkek, Serap -- Kawauchi, Daisuke -- Shih, David J H -- Hovestadt, Volker -- Zapatka, Marc -- Sturm, Dominik -- Jones, David T W -- Kool, Marcel -- Remke, Marc -- Cavalli, Florence M G -- Zuyderduyn, Scott -- Bader, Gary D -- VandenBerg, Scott -- Esparza, Lourdes Adriana -- Ryzhova, Marina -- Wang, Wei -- Wittmann, Andrea -- Stark, Sebastian -- Sieber, Laura -- Seker-Cin, Huriye -- Linke, Linda -- Kratochwil, Fabian -- Jager, Natalie -- Buchhalter, Ivo -- Imbusch, Charles D -- Zipprich, Gideon -- Raeder, Benjamin -- Schmidt, Sabine -- Diessl, Nicolle -- Wolf, Stephan -- Wiemann, Stefan -- Brors, Benedikt -- Lawerenz, Chris -- Eils, Jurgen -- Warnatz, Hans-Jorg -- Risch, Thomas -- Yaspo, Marie-Laure -- Weber, Ursula D -- Bartholomae, Cynthia C -- von Kalle, Christof -- Turanyi, Eszter -- Hauser, Peter -- Sanden, Emma -- Darabi, Anna -- Siesjo, Peter -- Sterba, Jaroslav -- Zitterbart, Karel -- Sumerauer, David -- van Sluis, Peter -- Versteeg, Rogier -- Volckmann, Richard -- Koster, Jan -- Schuhmann, Martin U -- Ebinger, Martin -- Grimes, H Leighton -- Robinson, Giles W -- Gajjar, Amar -- Mynarek, Martin -- von Hoff, Katja -- Rutkowski, Stefan -- Pietsch, Torsten -- Scheurlen, Wolfram -- Felsberg, Jorg -- Reifenberger, Guido -- Kulozik, Andreas E -- von Deimling, Andreas -- Witt, Olaf -- Eils, Roland -- Gilbertson, Richard J -- Korshunov, Andrey -- Taylor, Michael D -- Lichter, Peter -- Korbel, Jan O -- Wechsler-Reya, Robert J -- Pfister, Stefan M -- 5P30CA030199/CA/NCI NIH HHS/ -- P01 CA096832/CA/NCI NIH HHS/ -- P30 CA030199/CA/NCI NIH HHS/ -- P41GM103504/GM/NIGMS NIH HHS/ -- R01 CA159859/CA/NCI NIH HHS/ -- England -- Nature. 2014 Jul 24;511(7510):428-34. doi: 10.1038/nature13379.
