    Exome sequencing identifies frequent mutation of the SWI/SNF complex gene PBRM1 in renal carcinoma (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-01-21
    Description: The genetics of renal cancer is dominated by inactivation of the VHL tumour suppressor gene in clear cell carcinoma (ccRCC), the commonest histological subtype. A recent large-scale screen of approximately 3,500 genes by PCR-based exon re-sequencing identified several new cancer genes in ccRCC including UTX (also known as KDM6A), JARID1C (also known as KDM5C) and SETD2 (ref. 2). These genes encode enzymes that demethylate (UTX, JARID1C) or methylate (SETD2) key lysine residues of histone H3. Modification of the methylation state of these lysine residues of histone H3 regulates chromatin structure and is implicated in transcriptional control. However, together these mutations are present in fewer than 15% of ccRCC, suggesting the existence of additional, currently unidentified cancer genes. Here, we have sequenced the protein coding exome in a series of primary ccRCC and report the identification of the SWI/SNF chromatin remodelling complex gene PBRM1 (ref. 4) as a second major ccRCC cancer gene, with truncating mutations in 41% (92/227) of cases. These data further elucidate the somatic genetic architecture of ccRCC and emphasize the marked contribution of aberrant chromatin biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3030920/" 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/PMC3030920/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Varela, Ignacio -- Tarpey, Patrick -- Raine, Keiran -- Huang, Dachuan -- Ong, Choon Kiat -- Stephens, Philip -- Davies, Helen -- Jones, David -- Lin, Meng-Lay -- Teague, Jon -- Bignell, Graham -- Butler, Adam -- Cho, Juok -- Dalgliesh, Gillian L -- Galappaththige, Danushka -- Greenman, Chris -- Hardy, Claire -- Jia, Mingming -- Latimer, Calli -- Lau, King Wai -- Marshall, John -- McLaren, Stuart -- Menzies, Andrew -- Mudie, Laura -- Stebbings, Lucy -- Largaespada, David A -- Wessels, L F A -- Richard, Stephane -- Kahnoski, Richard J -- Anema, John -- Tuveson, David A -- Perez-Mancera, Pedro A -- Mustonen, Ville -- Fischer, Andrej -- Adams, David J -- Rust, Alistair -- Chan-on, Waraporn -- Subimerb, Chutima -- Dykema, Karl -- Furge, Kyle -- Campbell, Peter J -- Teh, Bin Tean -- Stratton, Michael R -- Futreal, P Andrew -- 077012/Wellcome Trust/United Kingdom -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- R01 CA113636/CA/NCI NIH HHS/ -- R01 CA134759/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- England -- Nature. 2011 Jan 27;469(7331):539-42. doi: 10.1038/nature09639.

    Clonal selection drives genetic divergence of metastatic medulloblastoma (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-02-22
    Description: Medulloblastoma, the most common malignant paediatric brain tumour, arises in the cerebellum and disseminates through the cerebrospinal fluid in the leptomeningeal space to coat the brain and spinal cord. Dissemination, a marker of poor prognosis, is found in up to 40% of children at diagnosis and in most children at the time of recurrence. Affected children therefore are treated with radiation to the entire developing brain and spinal cord, followed by high-dose chemotherapy, with the ensuing deleterious effects on the developing nervous system. The mechanisms of dissemination through the cerebrospinal fluid are poorly studied, and medulloblastoma metastases have been assumed to be biologically similar to the primary tumour. Here we show that in both mouse and human medulloblastoma, the metastases from an individual are extremely similar to each other but are divergent from the matched primary tumour. Clonal genetic events in the metastases can be demonstrated in a restricted subclone of the primary tumour, suggesting that only rare cells within the primary tumour have the ability to metastasize. Failure to account for the bicompartmental nature of metastatic medulloblastoma could be a major barrier to the development of effective targeted therapies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3288636/" 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/PMC3288636/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Xiaochong -- Northcott, Paul A -- Dubuc, Adrian -- Dupuy, Adam J -- Shih, David J H -- Witt, Hendrik -- Croul, Sidney -- Bouffet, Eric -- Fults, Daniel W -- Eberhart, Charles G -- Garzia, Livia -- Van Meter, Timothy -- Zagzag, David -- Jabado, Nada -- Schwartzentruber, Jeremy -- Majewski, Jacek -- Scheetz, Todd E -- Pfister, Stefan M -- Korshunov, Andrey -- Li, Xiao-Nan -- Scherer, Stephen W -- Cho, Yoon-Jae -- Akagi, Keiko -- MacDonald, Tobey J -- Koster, Jan -- McCabe, Martin G -- Sarver, Aaron L -- Collins, V Peter -- Weiss, William A -- Largaespada, David A -- Collier, Lara S -- Taylor, Michael D -- K01CA122183/CA/NCI NIH HHS/ -- NS055089/NS/NINDS NIH HHS/ -- R01 CA108622/CA/NCI NIH HHS/ -- R01 CA113636/CA/NCI NIH HHS/ -- R01 CA148699/CA/NCI NIH HHS/ -- R01 CA148699-03/CA/NCI NIH HHS/ -- R01 NS055089/NS/NINDS NIH HHS/ -- R01CA148699/CA/NCI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2012 Feb 15;482(7386):529-33. doi: 10.1038/nature10825.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Arthur and Sonia Labatt Brain Tumour Research Center, Program in Developmental and Stem Cell Biology, The Hospital for Sick Children, Toronto, Ontario M5G 1X8, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22343890" target="_blank"〉PubMed〈/a〉
