    Description: All cancers carry somatic mutations. A subset of these somatic alterations, termed driver mutations, confer selective growth advantage and are implicated in cancer development, whereas the remainder are passengers. Here we have sequenced the genomes of a malignant melanoma and a lymphoblastoid cell line from the same person, providing the first comprehensive catalogue of somatic mutations from an individual cancer. The catalogue provides remarkable insights into the forces that have shaped this cancer genome. The dominant mutational signature reflects DNA damage due to ultraviolet light exposure, a known risk factor for malignant melanoma, whereas the uneven distribution of mutations across the genome, with a lower prevalence in gene footprints, indicates that DNA repair has been preferentially deployed towards transcribed regions. The results illustrate the power of a cancer genome sequence to reveal traces of the DNA damage, repair, mutation and selection processes that were operative years before the cancer became symptomatic.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3145108/" 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/PMC3145108/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pleasance, Erin D -- Cheetham, R Keira -- Stephens, Philip J -- McBride, David J -- Humphray, Sean J -- Greenman, Chris D -- Varela, Ignacio -- Lin, Meng-Lay -- Ordonez, Gonzalo R -- Bignell, Graham R -- Ye, Kai -- Alipaz, Julie -- Bauer, Markus J -- Beare, David -- Butler, Adam -- Carter, Richard J -- Chen, Lina -- Cox, Anthony J -- Edkins, Sarah -- Kokko-Gonzales, Paula I -- Gormley, Niall A -- Grocock, Russell J -- Haudenschild, Christian D -- Hims, Matthew M -- James, Terena -- Jia, Mingming -- Kingsbury, Zoya -- Leroy, Catherine -- Marshall, John -- Menzies, Andrew -- Mudie, Laura J -- Ning, Zemin -- Royce, Tom -- Schulz-Trieglaff, Ole B -- Spiridou, Anastassia -- Stebbings, Lucy A -- Szajkowski, Lukasz -- Teague, Jon -- Williamson, David -- Chin, Lynda -- Ross, Mark T -- Campbell, Peter J -- Bentley, David R -- Futreal, P Andrew -- Stratton, Michael R -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- England -- Nature. 2010 Jan 14;463(7278):191-6. doi: 10.1038/nature08658.

    Description: Multiple somatic rearrangements are often found in cancer genomes; however, the underlying processes of rearrangement and their contribution to cancer development are poorly characterized. Here we use a paired-end sequencing strategy to identify somatic rearrangements in breast cancer genomes. There are more rearrangements in some breast cancers than previously appreciated. Rearrangements are more frequent over gene footprints and most are intrachromosomal. Multiple rearrangement architectures are present, but tandem duplications are particularly common in some cancers, perhaps reflecting a specific defect in DNA maintenance. Short overlapping sequences at most rearrangement junctions indicate that these have been mediated by non-homologous end-joining DNA repair, although varying sequence patterns indicate that multiple processes of this type are operative. Several expressed in-frame fusion genes were identified but none was recurrent. The study provides a new perspective on cancer genomes, highlighting the diversity of somatic rearrangements and their potential contribution to cancer development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3398135/" 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/PMC3398135/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, Philip J -- McBride, David J -- Lin, Meng-Lay -- Varela, Ignacio -- Pleasance, Erin D -- Simpson, Jared T -- Stebbings, Lucy A -- Leroy, Catherine -- Edkins, Sarah -- Mudie, Laura J -- Greenman, Chris D -- Jia, Mingming -- Latimer, Calli -- Teague, Jon W -- Lau, King Wai -- Burton, John -- Quail, Michael A -- Swerdlow, Harold -- Churcher, Carol -- Natrajan, Rachael -- Sieuwerts, Anieta M -- Martens, John W M -- Silver, Daniel P -- Langerod, Anita -- Russnes, Hege E G -- Foekens, John A -- Reis-Filho, Jorge S -- van 't Veer, Laura -- Richardson, Andrea L -- Borresen-Dale, Anne-Lise -- Campbell, Peter J -- Futreal, P Andrew -- Stratton, Michael R -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- CA089393/CA/NCI NIH HHS/ -- England -- Nature. 2009 Dec 24;462(7276):1005-10. doi: 10.1038/nature08645.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Hinxton, Cambridge CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20033038" target="_blank"〉PubMed〈/a〉

    Description: Pancreatic cancer is an aggressive malignancy with a five-year mortality of 97-98%, usually due to widespread metastatic disease. Previous studies indicate that this disease has a complex genomic landscape, with frequent copy number changes and point mutations, but genomic rearrangements have not been characterized in detail. Despite the clinical importance of metastasis, there remain fundamental questions about the clonal structures of metastatic tumours, including phylogenetic relationships among metastases, the scale of ongoing parallel evolution in metastatic and primary sites, and how the tumour disseminates. Here we harness advances in DNA sequencing to annotate genomic rearrangements in 13 patients with pancreatic cancer and explore clonal relationships among metastases. We find that pancreatic cancer acquires rearrangements indicative of telomere dysfunction and abnormal cell-cycle control, namely dysregulated G1-to-S-phase transition with intact G2-M checkpoint. These initiate amplification of cancer genes and occur predominantly in early cancer development rather than the later stages of the disease. Genomic instability frequently persists after cancer dissemination, resulting in ongoing, parallel and even convergent evolution among different metastases. We find evidence that there is genetic heterogeneity among metastasis-initiating cells, that seeding metastasis may require driver mutations beyond those required for primary tumours, and that phylogenetic trees across metastases show organ-specific branches. These data attest to the richness of genetic variation in cancer, brought about by the tandem forces of genomic instability and evolutionary selection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3137369/" 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/PMC3137369/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Campbell, Peter J -- Yachida, Shinichi -- Mudie, Laura J -- Stephens, Philip J -- Pleasance, Erin D -- Stebbings, Lucy A -- Morsberger, Laura A -- Latimer, Calli -- McLaren, Stuart -- Lin, Meng-Lay -- McBride, David J -- Varela, Ignacio -- Nik-Zainal, Serena A -- Leroy, Catherine -- Jia, Mingming -- Menzies, Andrew -- Butler, Adam P -- Teague, Jon W -- Griffin, Constance A -- Burton, John -- Swerdlow, Harold -- Quail, Michael A -- Stratton, Michael R -- Iacobuzio-Donahue, Christine -- Futreal, P Andrew -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- CA106610/CA/NCI NIH HHS/ -- CA140599/CA/NCI NIH HHS/ -- K08 CA106610/CA/NCI NIH HHS/ -- K08 CA106610-03/CA/NCI NIH HHS/ -- K08 CA106610-04/CA/NCI NIH HHS/ -- K08 CA106610-05/CA/NCI NIH HHS/ -- R01 CA140599/CA/NCI NIH HHS/ -- R01 CA140599-01/CA/NCI NIH HHS/ -- R01 CA140599-02/CA/NCI NIH HHS/ -- R01 CA140599-03/CA/NCI NIH HHS/ -- WT088340MA/Wellcome Trust/United Kingdom -- England -- Nature. 2010 Oct 28;467(7319):1109-13. doi: 10.1038/nature09460.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Genome Project, Wellcome Trust Sanger Institute, Hinxton CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20981101" target="_blank"〉PubMed〈/a〉

    Description: Cancer is driven by mutation. Worldwide, tobacco smoking is the principal lifestyle exposure that causes cancer, exerting carcinogenicity through 〉60 chemicals that bind and mutate DNA. Using massively parallel sequencing technology, we sequenced a small-cell lung cancer cell line, NCI-H209, to explore the mutational burden associated with tobacco smoking. A total of 22,910 somatic substitutions were identified, including 134 in coding exons. Multiple mutation signatures testify to the cocktail of carcinogens in tobacco smoke and their proclivities for particular bases and surrounding sequence context. Effects of transcription-coupled repair and a second, more general, expression-linked repair pathway were evident. We identified a tandem duplication that duplicates exons 3-8 of CHD7 in frame, and another two lines carrying PVT1-CHD7 fusion genes, indicating that CHD7 may be recurrently rearranged in this disease. These findings illustrate the potential for next-generation sequencing to provide unprecedented insights into mutational processes, cellular repair pathways and gene networks associated with cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880489/" 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/PMC2880489/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pleasance, Erin D -- Stephens, Philip J -- O'Meara, Sarah -- McBride, David J -- Meynert, Alison -- Jones, David -- Lin, Meng-Lay -- Beare, David -- Lau, King Wai -- Greenman, Chris -- Varela, Ignacio -- Nik-Zainal, Serena -- Davies, Helen R -- Ordonez, Gonzalo R -- Mudie, Laura J -- Latimer, Calli -- Edkins, Sarah -- Stebbings, Lucy -- Chen, Lina -- Jia, Mingming -- Leroy, Catherine -- Marshall, John -- Menzies, Andrew -- Butler, Adam -- Teague, Jon W -- Mangion, Jonathon -- Sun, Yongming A -- McLaughlin, Stephen F -- Peckham, Heather E -- Tsung, Eric F -- Costa, Gina L -- Lee, Clarence C -- Minna, John D -- Gazdar, Adi -- Birney, Ewan -- Rhodes, Michael D -- McKernan, Kevin J -- Stratton, Michael R -- Futreal, P Andrew -- Campbell, Peter J -- 077012/Wellcome Trust/United Kingdom -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- P50 CA070907/CA/NCI NIH HHS/ -- P50CA70907/CA/NCI NIH HHS/ -- England -- Nature. 2010 Jan 14;463(7278):184-90. doi: 10.1038/nature08629.

    Description: Clear cell renal cell carcinoma (ccRCC) is the most common form of adult kidney cancer, characterized by the presence of inactivating mutations in the VHL gene in most cases, and by infrequent somatic mutations in known cancer genes. To determine further the genetics of ccRCC, we have sequenced 101 cases through 3,544 protein-coding genes. Here we report the identification of inactivating mutations in two genes encoding enzymes involved in histone modification-SETD2, a histone H3 lysine 36 methyltransferase, and JARID1C (also known as KDM5C), a histone H3 lysine 4 demethylase-as well as mutations in the histone H3 lysine 27 demethylase, UTX (KMD6A), that we recently reported. The results highlight the role of mutations in components of the chromatin modification machinery in human cancer. Furthermore, NF2 mutations were found in non-VHL mutated ccRCC, and several other probable cancer genes were identified. These results indicate that substantial genetic heterogeneity exists in a cancer type dominated by mutations in a single gene, and that systematic screens will be key to fully determining the somatic genetic architecture of cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820242/" 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/PMC2820242/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dalgliesh, Gillian L -- Furge, Kyle -- Greenman, Chris -- Chen, Lina -- Bignell, Graham -- Butler, Adam -- Davies, Helen -- Edkins, Sarah -- Hardy, Claire -- Latimer, Calli -- Teague, Jon -- Andrews, Jenny -- Barthorpe, Syd -- Beare, Dave -- Buck, Gemma -- Campbell, Peter J -- Forbes, Simon -- Jia, Mingming -- Jones, David -- Knott, Henry -- Kok, Chai Yin -- Lau, King Wai -- Leroy, Catherine -- Lin, Meng-Lay -- McBride, David J -- Maddison, Mark -- Maguire, Simon -- McLay, Kirsten -- Menzies, Andrew -- Mironenko, Tatiana -- Mulderrig, Lee -- Mudie, Laura -- O'Meara, Sarah -- Pleasance, Erin -- Rajasingham, Arjunan -- Shepherd, Rebecca -- Smith, Raffaella -- Stebbings, Lucy -- Stephens, Philip -- Tang, Gurpreet -- Tarpey, Patrick S -- Turrell, Kelly -- Dykema, Karl J -- Khoo, Sok Kean -- Petillo, David -- Wondergem, Bill -- Anema, John -- Kahnoski, Richard J -- Teh, Bin Tean -- Stratton, Michael R -- Futreal, P Andrew -- 077012/Wellcome Trust/United Kingdom -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 082359/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- England -- Nature. 2010 Jan 21;463(7279):360-3. doi: 10.1038/nature08672.

    Description: All cancers carry somatic mutations in their genomes. A subset, known as driver mutations, confer clonal selective advantage on cancer cells and are causally implicated in oncogenesis, and the remainder are passenger mutations. The driver mutations and mutational processes operative in breast cancer have not yet been comprehensively explored. Here we examine the genomes of 100 tumours for somatic copy number changes and mutations in the coding exons of protein-coding genes. The number of somatic mutations varied markedly between individual tumours. We found strong correlations between mutation number, age at which cancer was diagnosed and cancer histological grade, and observed multiple mutational signatures, including one present in about ten per cent of tumours characterized by numerous mutations of cytosine at TpC dinucleotides. Driver mutations were identified in several new cancer genes including AKT2, ARID1B, CASP8, CDKN1B, MAP3K1, MAP3K13, NCOR1, SMARCD1 and TBX3. Among the 100 tumours, we found driver mutations in at least 40 cancer genes and 73 different combinations of mutated cancer genes. The results highlight the substantial genetic diversity underlying this common disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428862/" 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/PMC3428862/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, Philip J -- Tarpey, Patrick S -- Davies, Helen -- Van Loo, Peter -- Greenman, Chris -- Wedge, David C -- Nik-Zainal, Serena -- Martin, Sancha -- Varela, Ignacio -- Bignell, Graham R -- Yates, Lucy R -- Papaemmanuil, Elli -- Beare, David -- Butler, Adam -- Cheverton, Angela -- Gamble, John -- Hinton, Jonathan -- Jia, Mingming -- Jayakumar, Alagu -- Jones, David -- Latimer, Calli -- Lau, King Wai -- McLaren, Stuart -- McBride, David J -- Menzies, Andrew -- Mudie, Laura -- Raine, Keiran -- Rad, Roland -- Chapman, Michael Spencer -- Teague, Jon -- Easton, Douglas -- Langerod, Anita -- Oslo Breast Cancer Consortium (OSBREAC) -- Lee, Ming Ta Michael -- Shen, Chen-Yang -- Tee, Benita Tan Kiat -- Huimin, Bernice Wong -- Broeks, Annegien -- Vargas, Ana Cristina -- Turashvili, Gulisa -- Martens, John -- Fatima, Aquila -- Miron, Penelope -- Chin, Suet-Feung -- Thomas, Gilles -- Boyault, Sandrine -- Mariani, Odette -- Lakhani, Sunil R -- van de Vijver, Marc -- van 't Veer, Laura -- Foekens, John -- Desmedt, Christine -- Sotiriou, Christos -- Tutt, Andrew -- Caldas, Carlos -- Reis-Filho, Jorge S -- Aparicio, Samuel A J R -- Salomon, Anne Vincent -- Borresen-Dale, Anne-Lise -- Richardson, Andrea L -- Campbell, Peter J -- Futreal, P Andrew -- Stratton, Michael R -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- 10118/Cancer Research UK/United Kingdom -- CA089393/CA/NCI NIH HHS/ -- P30 CA016672/CA/NCI NIH HHS/ -- WT088340MA/Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- Chief Scientist Office/United Kingdom -- Department of Health/United Kingdom -- England -- Nature. 2012 May 16;486(7403):400-4. doi: 10.1038/nature11017.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Genome Project, Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22722201" target="_blank"〉PubMed〈/a〉

    Description: We present measurements of the angular diameter distance D A ( z ) and the Hubble parameter H ( z ) at z  = 0.35 using the anisotropy of the baryon acoustic oscillation (BAO) signal measured in the galaxy clustering distribution of the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) luminous red galaxy (LRG) sample. Our work is the first to apply density-field reconstruction to an anisotropic analysis of the acoustic peak. Reconstruction partially removes the effects of non-linear evolution and redshift-space distortions in order to sharpen the acoustic signal. We present the theoretical framework behind the anisotropic BAO signal and give a detailed account of the fitting model we use to extract this signal from the data. Our method focuses only on the acoustic peak anisotropy, rather than the more model-dependent anisotropic information from the broad-band power. We test the robustness of our analysis methods on 160 Large Suite of Dark Matter Simulation DR7 mock catalogues and find that our models are unbiased at the ~0.2 per cent level in measuring the BAO anisotropy. After reconstruction we measure D A ( z  = 0.35) = 1050 ± 38 Mpc and H ( z  = 0.35) = 84.4 ± 7.0 km s –1  Mpc –1 assuming a sound horizon of r s  = 152.76 Mpc. Note that these measurements are correlated with a correlation coefficient of 0.57. This represents a factor of 1.4 improvement in the error on D A relative to the pre-reconstruction case; a factor of 1.2 improvement is seen for H .

    Description: The nature and pace of genome mutation is largely unknown. Because standard methods sequence DNA from populations of cells, the genetic composition of individual cells is lost, de novo mutations in cells are concealed within the bulk signal and per cell cycle mutation rates and mechanisms remain elusive. Although single-cell genome analyses could resolve these problems, such analyses are error-prone because of whole-genome amplification (WGA) artefacts and are limited in the types of DNA mutation that can be discerned. We developed methods for paired-end sequence analysis of single-cell WGA products that enable (i) detecting multiple classes of DNA mutation, (ii) distinguishing DNA copy number changes from allelic WGA-amplification artefacts by the discovery of matching aberrantly mapping read pairs among the surfeit of paired-end WGA and mapping artefacts and (iii) delineating the break points and architecture of structural variants. By applying the methods, we capture DNA copy number changes acquired over one cell cycle in breast cancer cells and in blastomeres derived from a human zygote after in vitro fertilization. Furthermore, we were able to discover and fine-map a heritable inter-chromosomal rearrangement t(1;16)(p36;p12) by sequencing a single blastomere. The methods will expedite applications in basic genome research and provide a stepping stone to novel approaches for clinical genetic diagnosis.
