    Description: Breast carcinoma is the leading cause of cancer-related mortality in women worldwide, with an estimated 1.38 million new cases and 458,000 deaths in 2008 alone. This malignancy represents a heterogeneous group of tumours with characteristic molecular features, prognosis and responses to available therapy. Recurrent somatic alterations in breast cancer have been described, including mutations and copy number alterations, notably ERBB2 amplifications, the first successful therapy target defined by a genomic aberration. Previous DNA sequencing studies of breast cancer genomes have revealed additional candidate mutations and gene rearrangements. Here we report the whole-exome sequences of DNA from 103 human breast cancers of diverse subtypes from patients in Mexico and Vietnam compared to matched-normal DNA, together with whole-genome sequences of 22 breast cancer/normal pairs. Beyond confirming recurrent somatic mutations in PIK3CA, TP53, AKT1, GATA3 and MAP3K1, we discovered recurrent mutations in the CBFB transcription factor gene and deletions of its partner RUNX1. Furthermore, we have identified a recurrent MAGI3-AKT3 fusion enriched in triple-negative breast cancer lacking oestrogen and progesterone receptors and ERBB2 expression. The MAGI3-AKT3 fusion leads to constitutive activation of AKT kinase, which is abolished by treatment with an ATP-competitive AKT small-molecule inhibitor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4148686/" 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/PMC4148686/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banerji, Shantanu -- Cibulskis, Kristian -- Rangel-Escareno, Claudia -- Brown, Kristin K -- Carter, Scott L -- Frederick, Abbie M -- Lawrence, Michael S -- Sivachenko, Andrey Y -- Sougnez, Carrie -- Zou, Lihua -- Cortes, Maria L -- Fernandez-Lopez, Juan C -- Peng, Shouyong -- Ardlie, Kristin G -- Auclair, Daniel -- Bautista-Pina, Veronica -- Duke, Fujiko -- Francis, Joshua -- Jung, Joonil -- Maffuz-Aziz, Antonio -- Onofrio, Robert C -- Parkin, Melissa -- Pho, Nam H -- Quintanar-Jurado, Valeria -- Ramos, Alex H -- Rebollar-Vega, Rosa -- Rodriguez-Cuevas, Sergio -- Romero-Cordoba, Sandra L -- Schumacher, Steven E -- Stransky, Nicolas -- Thompson, Kristin M -- Uribe-Figueroa, Laura -- Baselga, Jose -- Beroukhim, Rameen -- Polyak, Kornelia -- Sgroi, Dennis C -- Richardson, Andrea L -- Jimenez-Sanchez, Gerardo -- Lander, Eric S -- Gabriel, Stacey B -- Garraway, Levi A -- Golub, Todd R -- Melendez-Zajgla, Jorge -- Toker, Alex -- Getz, Gad -- Hidalgo-Miranda, Alfredo -- Meyerson, Matthew -- CA089393/CA/NCI NIH HHS/ -- CA122099/CA/NCI NIH HHS/ -- R01 CA122099/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Jun 20;486(7403):405-9. doi: 10.1038/nature11154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Broad Institute of MIT and Harvard, Cambridge, Massachusetts 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22722202" target="_blank"〉PubMed〈/a〉

    Description: Medulloblastomas are the most common malignant brain tumours in children. Identifying and understanding the genetic events that drive these tumours is critical for the development of more effective diagnostic, prognostic and therapeutic strategies. Recently, our group and others described distinct molecular subtypes of medulloblastoma on the basis of transcriptional and copy number profiles. Here we use whole-exome hybrid capture and deep sequencing to identify somatic mutations across the coding regions of 92 primary medulloblastoma/normal pairs. Overall, medulloblastomas have low mutation rates consistent with other paediatric tumours, with a median of 0.35 non-silent mutations per megabase. We identified twelve genes mutated at statistically significant frequencies, including previously known mutated genes in medulloblastoma such as CTNNB1, PTCH1, MLL2, SMARCA4 and TP53. Recurrent somatic mutations were newly identified in an RNA helicase gene, DDX3X, often concurrent with CTNNB1 mutations, and in the nuclear co-repressor (N-CoR) complex genes GPS2, BCOR and LDB1. We show that mutant DDX3X potentiates transactivation of a TCF promoter and enhances cell viability in combination with mutant, but not wild-type, beta-catenin. Together, our study reveals the alteration of WNT, hedgehog, histone methyltransferase and now N-CoR pathways across medulloblastomas and within specific subtypes of this disease, and nominates the RNA helicase DDX3X as a component of pathogenic beta-catenin signalling in medulloblastoma.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3413789/" 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/PMC3413789/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pugh, Trevor J -- Weeraratne, Shyamal Dilhan -- Archer, Tenley C -- Pomeranz Krummel, Daniel A -- Auclair, Daniel -- Bochicchio, James -- Carneiro, Mauricio O -- Carter, Scott L -- Cibulskis, Kristian -- Erlich, Rachel L -- Greulich, Heidi -- Lawrence, Michael S -- Lennon, Niall J -- McKenna, Aaron -- Meldrim, James -- Ramos, Alex H -- Ross, Michael G -- Russ, Carsten -- Shefler, Erica -- Sivachenko, Andrey -- Sogoloff, Brian -- Stojanov, Petar -- Tamayo, Pablo -- Mesirov, Jill P -- Amani, Vladimir -- Teider, Natalia -- Sengupta, Soma -- Francois, Jessica Pierre -- Northcott, Paul A -- Taylor, Michael D -- Yu, Furong -- Crabtree, Gerald R -- Kautzman, Amanda G -- Gabriel, Stacey B -- Getz, Gad -- Jager, Natalie -- Jones, David T W -- Lichter, Peter -- Pfister, Stefan M -- Roberts, Thomas M -- Meyerson, Matthew -- Pomeroy, Scott L -- Cho, Yoon-Jae -- CA050661/CA/NCI NIH HHS/ -- L40 NS063706/NS/NINDS NIH HHS/ -- P30 HD018655/HD/NICHD NIH HHS/ -- P30 HD18655/HD/NICHD NIH HHS/ -- R01 CA030002/CA/NCI NIH HHS/ -- R01 CA105607/CA/NCI NIH HHS/ -- R01 CA109467/CA/NCI NIH HHS/ -- R01 CA148699/CA/NCI NIH HHS/ -- R01 CA154480/CA/NCI NIH HHS/ -- R01 NS046789/NS/NINDS NIH HHS/ -- R01CA105607/CA/NCI NIH HHS/ -- R01CA109467/CA/NCI NIH HHS/ -- R01CA148699/CA/NCI NIH HHS/ -- R25 NS070682/NS/NINDS NIH HHS/ -- R25NS070682/NS/NINDS NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54HG003067/HG/NHGRI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Aug 2;488(7409):106-10. doi: 10.1038/nature11329.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of MIT and Harvard, Cambridge, Massachusetts 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22820256" target="_blank"〉PubMed〈/a〉

    Description: Cervical cancer is responsible for 10-15% of cancer-related deaths in women worldwide. The aetiological role of infection with high-risk human papilloma viruses (HPVs) in cervical carcinomas is well established. Previous studies have also implicated somatic mutations in PIK3CA, PTEN, TP53, STK11 and KRAS as well as several copy-number alterations in the pathogenesis of cervical carcinomas. Here we report whole-exome sequencing analysis of 115 cervical carcinoma-normal paired samples, transcriptome sequencing of 79 cases and whole-genome sequencing of 14 tumour-normal pairs. Previously unknown somatic mutations in 79 primary squamous cell carcinomas include recurrent E322K substitutions in the MAPK1 gene (8%), inactivating mutations in the HLA-B gene (9%), and mutations in EP300 (16%), FBXW7 (15%), NFE2L2 (4%), TP53 (5%) and ERBB2 (6%). We also observe somatic ELF3 (13%) and CBFB (8%) mutations in 24 adenocarcinomas. Squamous cell carcinomas have higher frequencies of somatic nucleotide substitutions occurring at cytosines preceded by thymines (Tp*C sites) than adenocarcinomas. Gene expression levels at HPV integration sites were statistically significantly higher in tumours with HPV integration compared with expression of the same genes in tumours without viral integration at the same site. These data demonstrate several recurrent genomic alterations in cervical carcinomas that suggest new strategies to combat this disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4161954/" 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/PMC4161954/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ojesina, Akinyemi I -- Lichtenstein, Lee -- Freeman, Samuel S -- Pedamallu, Chandra Sekhar -- Imaz-Rosshandler, Ivan -- Pugh, Trevor J -- Cherniack, Andrew D -- Ambrogio, Lauren -- Cibulskis, Kristian -- Bertelsen, Bjorn -- Romero-Cordoba, Sandra -- Trevino, Victor -- Vazquez-Santillan, Karla -- Guadarrama, Alberto Salido -- Wright, Alexi A -- Rosenberg, Mara W -- Duke, Fujiko -- Kaplan, Bethany -- Wang, Rui -- Nickerson, Elizabeth -- Walline, Heather M -- Lawrence, Michael S -- Stewart, Chip -- Carter, Scott L -- McKenna, Aaron -- Rodriguez-Sanchez, Iram P -- Espinosa-Castilla, Magali -- Woie, Kathrine -- Bjorge, Line -- Wik, Elisabeth -- Halle, Mari K -- Hoivik, Erling A -- Krakstad, Camilla -- Gabino, Nayeli Belem -- Gomez-Macias, Gabriela Sofia -- Valdez-Chapa, Lezmes D -- Garza-Rodriguez, Maria Lourdes -- Maytorena, German -- Vazquez, Jorge -- Rodea, Carlos -- Cravioto, Adrian -- Cortes, Maria L -- Greulich, Heidi -- Crum, Christopher P -- Neuberg, Donna S -- Hidalgo-Miranda, Alfredo -- Escareno, Claudia Rangel -- Akslen, Lars A -- Carey, Thomas E -- Vintermyr, Olav K -- Gabriel, Stacey B -- Barrera-Saldana, Hugo A -- Melendez-Zajgla, Jorge -- Getz, Gad -- Salvesen, Helga B -- Meyerson, Matthew -- K07 CA166210/CA/NCI NIH HHS/ -- T32 CA009676/CA/NCI NIH HHS/ -- England -- Nature. 2014 Feb 20;506(7488):371-5. doi: 10.1038/nature12881.

    Description: Head and neck squamous cell carcinoma (HNSCC) is a common, morbid, and frequently lethal malignancy. To uncover its mutational spectrum, we analyzed whole-exome sequencing data from 74 tumor-normal pairs. The majority exhibited a mutational profile consistent with tobacco exposure; human papillomavirus was detectable by sequencing DNA from infected tumors. In addition to identifying previously known HNSCC genes (TP53, CDKN2A, PTEN, PIK3CA, and HRAS), our analysis revealed many genes not previously implicated in this malignancy. At least 30% of cases harbored mutations in genes that regulate squamous differentiation (for example, NOTCH1, IRF6, and TP63), implicating its dysregulation as a major driver of HNSCC carcinogenesis. More generally, the results indicate the ability of large-scale sequencing to reveal fundamental tumorigenic mechanisms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3415217/" 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/PMC3415217/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stransky, Nicolas -- Egloff, Ann Marie -- Tward, Aaron D -- Kostic, Aleksandar D -- Cibulskis, Kristian -- Sivachenko, Andrey -- Kryukov, Gregory V -- Lawrence, Michael S -- Sougnez, Carrie -- McKenna, Aaron -- Shefler, Erica -- Ramos, Alex H -- Stojanov, Petar -- Carter, Scott L -- Voet, Douglas -- Cortes, Maria L -- Auclair, Daniel -- Berger, Michael F -- Saksena, Gordon -- Guiducci, Candace -- Onofrio, Robert C -- Parkin, Melissa -- Romkes, Marjorie -- Weissfeld, Joel L -- Seethala, Raja R -- Wang, Lin -- Rangel-Escareno, Claudia -- Fernandez-Lopez, Juan Carlos -- Hidalgo-Miranda, Alfredo -- Melendez-Zajgla, Jorge -- Winckler, Wendy -- Ardlie, Kristin -- Gabriel, Stacey B -- Meyerson, Matthew -- Lander, Eric S -- Getz, Gad -- Golub, Todd R -- Garraway, Levi A -- Grandis, Jennifer R -- P50 CA097190/CA/NCI NIH HHS/ -- R01 CA077308/CA/NCI NIH HHS/ -- R01 CA098372/CA/NCI NIH HHS/ -- UL1 TR000005/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1157-60. doi: 10.1126/science.1208130.

    Description: Multiple myeloma is an incurable malignancy of plasma cells, and its pathogenesis is poorly understood. Here we report the massively parallel sequencing of 38 tumour genomes and their comparison to matched normal DNAs. Several new and unexpected oncogenic mechanisms were suggested by the pattern of somatic mutation across the data set. These include the mutation of genes involved in protein translation (seen in nearly half of the patients), genes involved in histone methylation, and genes involved in blood coagulation. In addition, a broader than anticipated role of NF-kappaB signalling was indicated by mutations in 11 members of the NF-kappaB pathway. Of potential immediate clinical relevance, activating mutations of the kinase BRAF were observed in 4% of patients, suggesting the evaluation of BRAF inhibitors in multiple myeloma clinical trials. These results indicate that cancer genome sequencing of large collections of samples will yield new insights into cancer not anticipated by existing knowledge.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3560292/" 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/PMC3560292/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chapman, Michael A -- Lawrence, Michael S -- Keats, Jonathan J -- Cibulskis, Kristian -- Sougnez, Carrie -- Schinzel, Anna C -- Harview, Christina L -- Brunet, Jean-Philippe -- Ahmann, Gregory J -- Adli, Mazhar -- Anderson, Kenneth C -- Ardlie, Kristin G -- Auclair, Daniel -- Baker, Angela -- Bergsagel, P Leif -- Bernstein, Bradley E -- Drier, Yotam -- Fonseca, Rafael -- Gabriel, Stacey B -- Hofmeister, Craig C -- Jagannath, Sundar -- Jakubowiak, Andrzej J -- Krishnan, Amrita -- Levy, Joan -- Liefeld, Ted -- Lonial, Sagar -- Mahan, Scott -- Mfuko, Bunmi -- Monti, Stefano -- Perkins, Louise M -- Onofrio, Robb -- Pugh, Trevor J -- Rajkumar, S Vincent -- Ramos, Alex H -- Siegel, David S -- Sivachenko, Andrey -- Stewart, A Keith -- Trudel, Suzanne -- Vij, Ravi -- Voet, Douglas -- Winckler, Wendy -- Zimmerman, Todd -- Carpten, John -- Trent, Jeff -- Hahn, William C -- Garraway, Levi A -- Meyerson, Matthew -- Lander, Eric S -- Getz, Gad -- Golub, Todd R -- K12 CA133250/CA/NCI NIH HHS/ -- R01 AG020686/AG/NIA NIH HHS/ -- R01 AG020686-07/AG/NIA NIH HHS/ -- R01 CA133115/CA/NCI NIH HHS/ -- R01 CA133115-04/CA/NCI NIH HHS/ -- R01 CA133966/CA/NCI NIH HHS/ -- R01 CA133966-03/CA/NCI NIH HHS/ -- England -- Nature. 2011 Mar 24;471(7339):467-72. doi: 10.1038/nature09837.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Eli and Edythe L.

    Description: Melanoma is notable for its metastatic propensity, lethality in the advanced setting and association with ultraviolet exposure early in life. To obtain a comprehensive genomic view of melanoma in humans, we sequenced the genomes of 25 metastatic melanomas and matched germline DNA. A wide range of point mutation rates was observed: lowest in melanomas whose primaries arose on non-ultraviolet-exposed hairless skin of the extremities (3 and 14 per megabase (Mb) of genome), intermediate in those originating from hair-bearing skin of the trunk (5-55 per Mb), and highest in a patient with a documented history of chronic sun exposure (111 per Mb). Analysis of whole-genome sequence data identified PREX2 (phosphatidylinositol-3,4,5-trisphosphate-dependent Rac exchange factor 2)--a PTEN-interacting protein and negative regulator of PTEN in breast cancer--as a significantly mutated gene with a mutation frequency of approximately 14% in an independent extension cohort of 107 human melanomas. PREX2 mutations are biologically relevant, as ectopic expression of mutant PREX2 accelerated tumour formation of immortalized human melanocytes in vivo. Thus, whole-genome sequencing of human melanoma tumours revealed genomic evidence of ultraviolet pathogenesis and discovered a new recurrently mutated gene in melanoma.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367798/" 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/PMC3367798/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berger, Michael F -- Hodis, Eran -- Heffernan, Timothy P -- Deribe, Yonathan Lissanu -- Lawrence, Michael S -- Protopopov, Alexei -- Ivanova, Elena -- Watson, Ian R -- Nickerson, Elizabeth -- Ghosh, Papia -- Zhang, Hailei -- Zeid, Rhamy -- Ren, Xiaojia -- Cibulskis, Kristian -- Sivachenko, Andrey Y -- Wagle, Nikhil -- Sucker, Antje -- Sougnez, Carrie -- Onofrio, Robert -- Ambrogio, Lauren -- Auclair, Daniel -- Fennell, Timothy -- Carter, Scott L -- Drier, Yotam -- Stojanov, Petar -- Singer, Meredith A -- Voet, Douglas -- Jing, Rui -- Saksena, Gordon -- Barretina, Jordi -- Ramos, Alex H -- Pugh, Trevor J -- Stransky, Nicolas -- Parkin, Melissa -- Winckler, Wendy -- Mahan, Scott -- Ardlie, Kristin -- Baldwin, Jennifer -- Wargo, Jennifer -- Schadendorf, Dirk -- Meyerson, Matthew -- Gabriel, Stacey B -- Golub, Todd R -- Wagner, Stephan N -- Lander, Eric S -- Getz, Gad -- Chin, Lynda -- Garraway, Levi A -- DP2 OD002750/OD/NIH HHS/ -- DP2 OD002750-01/OD/NIH HHS/ -- R33 CA126674/CA/NCI NIH HHS/ -- R33 CA126674-03/CA/NCI NIH HHS/ -- R33 CA126674-04/CA/NCI NIH HHS/ -- R33 CA155554/CA/NCI NIH HHS/ -- R33 CA155554-01/CA/NCI NIH HHS/ -- T32 CA009172/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 May 9;485(7399):502-6. doi: 10.1038/nature11071.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Broad Institute of Harvard and MIT, Cambridge, Massachusetts 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22622578" target="_blank"〉PubMed〈/a〉

    Description: Major international projects are underway that are aimed at creating a comprehensive catalogue of all the genes responsible for the initiation and progression of cancer. These studies involve the sequencing of matched tumour-normal samples followed by mathematical analysis to identify those genes in which mutations occur more frequently than expected by random chance. Here we describe a fundamental problem with cancer genome studies: as the sample size increases, the list of putatively significant genes produced by current analytical methods burgeons into the hundreds. The list includes many implausible genes (such as those encoding olfactory receptors and the muscle protein titin), suggesting extensive false-positive findings that overshadow true driver events. We show that this problem stems largely from mutational heterogeneity and provide a novel analytical methodology, MutSigCV, for resolving the problem. We apply MutSigCV to exome sequences from 3,083 tumour-normal pairs and discover extraordinary variation in mutation frequency and spectrum within cancer types, which sheds light on mutational processes and disease aetiology, and in mutation frequency across the genome, which is strongly correlated with DNA replication timing and also with transcriptional activity. By incorporating mutational heterogeneity into the analyses, MutSigCV is able to eliminate most of the apparent artefactual findings and enable the identification of genes truly associated with cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3919509/" 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/PMC3919509/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lawrence, Michael S -- Stojanov, Petar -- Polak, Paz -- Kryukov, Gregory V -- Cibulskis, Kristian -- Sivachenko, Andrey -- Carter, Scott L -- Stewart, Chip -- Mermel, Craig H -- Roberts, Steven A -- Kiezun, Adam -- Hammerman, Peter S -- McKenna, Aaron -- Drier, Yotam -- Zou, Lihua -- Ramos, Alex H -- Pugh, Trevor J -- Stransky, Nicolas -- Helman, Elena -- Kim, Jaegil -- Sougnez, Carrie -- Ambrogio, Lauren -- Nickerson, Elizabeth -- Shefler, Erica -- Cortes, Maria L -- Auclair, Daniel -- Saksena, Gordon -- Voet, Douglas -- Noble, Michael -- DiCara, Daniel -- Lin, Pei -- Lichtenstein, Lee -- Heiman, David I -- Fennell, Timothy -- Imielinski, Marcin -- Hernandez, Bryan -- Hodis, Eran -- Baca, Sylvan -- Dulak, Austin M -- Lohr, Jens -- Landau, Dan-Avi -- Wu, Catherine J -- Melendez-Zajgla, Jorge -- Hidalgo-Miranda, Alfredo -- Koren, Amnon -- McCarroll, Steven A -- Mora, Jaume -- Lee, Ryan S -- Crompton, Brian -- Onofrio, Robert -- Parkin, Melissa -- Winckler, Wendy -- Ardlie, Kristin -- Gabriel, Stacey B -- Roberts, Charles W M -- Biegel, Jaclyn A -- Stegmaier, Kimberly -- Bass, Adam J -- Garraway, Levi A -- Meyerson, Matthew -- Golub, Todd R -- Gordenin, Dmitry A -- Sunyaev, Shamil -- Lander, Eric S -- Getz, Gad -- ES065073/ES/NIEHS NIH HHS/ -- T32 CA009172/CA/NCI NIH HHS/ -- T32 CA009216/CA/NCI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- U24 CA143845/CA/NCI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- England -- Nature. 2013 Jul 11;499(7457):214-8. doi: 10.1038/nature12213.

    Description: Prostate cancer is the second most common cause of male cancer deaths in the United States. However, the full range of prostate cancer genomic alterations is incompletely characterized. Here we present the complete sequence of seven primary human prostate cancers and their paired normal counterparts. Several tumours contained complex chains of balanced (that is, 'copy-neutral') rearrangements that occurred within or adjacent to known cancer genes. Rearrangement breakpoints were enriched near open chromatin, androgen receptor and ERG DNA binding sites in the setting of the ETS gene fusion TMPRSS2-ERG, but inversely correlated with these regions in tumours lacking ETS fusions. This observation suggests a link between chromatin or transcriptional regulation and the genesis of genomic aberrations. Three tumours contained rearrangements that disrupted CADM2, and four harboured events disrupting either PTEN (unbalanced events), a prostate tumour suppressor, or MAGI2 (balanced events), a PTEN interacting protein not previously implicated in prostate tumorigenesis. Thus, genomic rearrangements may arise from transcriptional or chromatin aberrancies and engage prostate tumorigenic mechanisms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3075885/" 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/PMC3075885/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berger, Michael F -- Lawrence, Michael S -- Demichelis, Francesca -- Drier, Yotam -- Cibulskis, Kristian -- Sivachenko, Andrey Y -- Sboner, Andrea -- Esgueva, Raquel -- Pflueger, Dorothee -- Sougnez, Carrie -- Onofrio, Robert -- Carter, Scott L -- Park, Kyung -- Habegger, Lukas -- Ambrogio, Lauren -- Fennell, Timothy -- Parkin, Melissa -- Saksena, Gordon -- Voet, Douglas -- Ramos, Alex H -- Pugh, Trevor J -- Wilkinson, Jane -- Fisher, Sheila -- Winckler, Wendy -- Mahan, Scott -- Ardlie, Kristin -- Baldwin, Jennifer -- Simons, Jonathan W -- Kitabayashi, Naoki -- MacDonald, Theresa Y -- Kantoff, Philip W -- Chin, Lynda -- Gabriel, Stacey B -- Gerstein, Mark B -- Golub, Todd R -- Meyerson, Matthew -- Tewari, Ashutosh -- Lander, Eric S -- Getz, Gad -- Rubin, Mark A -- Garraway, Levi A -- 2 P50 CA090381-11/CA/NCI NIH HHS/ -- DP2 OD002750/OD/NIH HHS/ -- DP2 OD002750-01/OD/NIH HHS/ -- R33 CA126674/CA/NCI NIH HHS/ -- R33 CA126674-03/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Feb 10;470(7333):214-20. doi: 10.1038/nature09744.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Broad Institute of Harvard and MIT, Cambridge, Massachusetts 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21307934" target="_blank"〉PubMed〈/a〉

    Description: Which genetic alterations drive tumorigenesis and how they evolve over the course of disease and therapy are central questions in cancer biology. Here we identify 44 recurrently mutated genes and 11 recurrent somatic copy number variations through whole-exome sequencing of 538 chronic lymphocytic leukaemia (CLL) and matched germline DNA samples, 278 of which were collected in a prospective clinical trial. These include previously unrecognized putative cancer drivers (RPS15, IKZF3), and collectively identify RNA processing and export, MYC activity, and MAPK signalling as central pathways involved in CLL. Clonality analysis of this large data set further enabled reconstruction of temporal relationships between driver events. Direct comparison between matched pre-treatment and relapse samples from 59 patients demonstrated highly frequent clonal evolution. Thus, large sequencing data sets of clinically informative samples enable the discovery of novel genes associated with cancer, the network of relationships between the driver events, and their impact on disease relapse and clinical outcome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landau, Dan A -- Tausch, Eugen -- Taylor-Weiner, Amaro N -- Stewart, Chip -- Reiter, Johannes G -- Bahlo, Jasmin -- Kluth, Sandra -- Bozic, Ivana -- Lawrence, Mike -- Bottcher, Sebastian -- Carter, Scott L -- Cibulskis, Kristian -- Mertens, Daniel -- Sougnez, Carrie L -- Rosenberg, Mara -- Hess, Julian M -- Edelmann, Jennifer -- Kless, Sabrina -- Kneba, Michael -- Ritgen, Matthias -- Fink, Anna -- Fischer, Kirsten -- Gabriel, Stacey -- Lander, Eric S -- Nowak, Martin A -- Dohner, Hartmut -- Hallek, Michael -- Neuberg, Donna -- Getz, Gad -- Stilgenbauer, Stephan -- Wu, Catherine J -- 1K01ES025431-01/ES/NIEHS NIH HHS/ -- 1R01CA182461-02/CA/NCI NIH HHS/ -- 1R01CA184922-01/CA/NCI NIH HHS/ -- 1U10CA180861-01/CA/NCI NIH HHS/ -- K01 ES025431/ES/NIEHS NIH HHS/ -- R01 HL116452/HL/NHLBI NIH HHS/ -- U10 CA180861/CA/NCI NIH HHS/ -- U54HG003067/HG/NHGRI NIH HHS/ -- England -- Nature. 2015 Oct 22;526(7574):525-30. doi: 10.1038/nature15395.

    Abstract: Medulloblastomas are themost commonmalignant brain tumours in children(1). Identifying and understanding the genetic events that drive these tumours is critical for the development of more effective diagnostic, prognostic and therapeutic strategies. Recently, our group and others described distinct molecular subtypes ofmedulloblastoma on the basis of transcriptional and copy number profiles(2-5). Here we use whole-exome hybrid capture and deep sequencing to identify somatic mutations across the coding regions of 92 primary medulloblastoma/normal pairs. Overall, medulloblastomas have low mutation rates consistent with other paediatric tumours, with a median of 0.35 non-silent mutations per megabase. We identified twelve genes mutated at statistically significant frequencies, including previously known mutated genes in medulloblastoma such as CTNNB1, PTCH1, MLL2, SMARCA4 andTP53. Recurrent somatic mutations were newly identified in an RNA helicase gene, DDX3X, often concurrent with CTNNB1 mutations, and in the nuclear co-repressor (N-CoR) complex genes GPS2, BCOR and LDB1. We show that mutant DDX3X potentiates transactivation of a TCF promoter and enhances cell viability in combination with mutant, but not wild-type, beta-catenin. Together, our study reveals the alteration ofWNT, hedgehog, histone methyltransferase and now N-CoR pathways across medulloblastomas and within specific subtypes of this disease, and nominates theRNA helicase DDX3X as a component of pathogenic b-catenin signalling in medulloblastoma.
