    Description: The early Eocene epoch was characterized by extreme global warmth, which in terrestrial settings was characterized by an expansion of near-tropical vegetation belts into the high latitudes. During the middle to late Eocene, global cooling caused the retreat of tropical vegetation to lower latitudes. In high-latitude settings, near-tropical vegetation was replaced by temperate floras. This floral change has recently been traced as far south as Antarctica, where along the Wilkes Land margin paratropical forests thrived during the early Eocene and temperate Nothofagus forests developed during the middle Eocene. Here we provide both qualitative and quantitative palynological data for this floral turnover based on a sporomorph record recovered at Integrated Ocean Drilling Program (IODP) Site U1356 off the Wilkes Land margin. Following the nearest living relative concept and based on a comparison with modern vegetation types, we examine the structure and diversity patterns of the Eocene vegetation along the Wilkes Land margin. Our results indicate that the early Eocene forests along the Wilkes Land margin were characterized by a diverse canopy composed of plants that today occur in tropical settings; their richness pattern was similar to that of present-day forests from New Caledonia. The middle Eocene forests were characterized by a canopy dominated by Nothofagus and exhibited richness patterns similar to modern Nothofagus forests from New Zealand.

    Description: The warmest global climates of the past 65 million years occurred during the early Eocene epoch (about 55 to 48 million years ago), when the Equator-to-pole temperature gradients were much smaller than today (doi:10.1130/0091-7613(1995)023〈1044:ECCALT〉2.3.CO;2, doi:10.1038/nature08399) and atmospheric carbon dioxide levels were in excess of one thousand parts per million by volume (doi:10.1016/j.gca.2003.09.002, doi:10.1038/ngeo1186). Recently the early Eocene has received considerable interest because it may provide insight into the response of Earth's climate and biosphere to the high atmospheric carbon dioxide levels that are expected in the near future (doi:10.1007/s10584-011-0156-z) as a consequence of unabated anthropogenic carbon emissions (doi:10.1038/ngeo1186, doi:10.1038/nature06588). Climatic conditions of the early Eocene 'greenhouse world', however, are poorly constrained in critical regions, particularly Antarctica. Here we present a well-dated record of early Eocene climate on Antarctica from an ocean sediment core recovered off the Wilkes Land coast of East Antarctica. The information from biotic climate proxies (pollen and spores) and independent organic geochemical climate proxies (indices based on branched tetraether lipids) yields quantitative, seasonal temperature reconstructions for the early Eocene greenhouse world on Antarctica. We show that the climate in lowland settings along the Wilkes Land coast (at a palaeolatitude of about 70° south) supported the growth of highly diverse, near-tropical forests characterized by mesothermal to megathermal floral elements including palms and Bombacoideae. Notably, winters were extremely mild (warmer than 10 °C) and essentially frost-free despite polar darkness, which provides a critical new constraint for the validation of climate models and for understanding the response of high-latitude terrestrial ecosystems to increased carbon dioxide forcing.

    Description: Chronic lymphocytic leukaemia (CLL), the most frequent leukaemia in adults in Western countries, is a heterogeneous disease with variable clinical presentation and evolution. Two major molecular subtypes can be distinguished, characterized respectively by a high or low number of somatic hypermutations in the variable region of immunoglobulin genes. The molecular changes leading to the pathogenesis of the disease are still poorly understood. Here we performed whole-genome sequencing of four cases of CLL and identified 46 somatic mutations that potentially affect gene function. Further analysis of these mutations in 363 patients with CLL identified four genes that are recurrently mutated: notch 1 (NOTCH1), exportin 1 (XPO1), myeloid differentiation primary response gene 88 (MYD88) and kelch-like 6 (KLHL6). Mutations in MYD88 and KLHL6 are predominant in cases of CLL with mutated immunoglobulin genes, whereas NOTCH1 and XPO1 mutations are mainly detected in patients with unmutated immunoglobulins. The patterns of somatic mutation, supported by functional and clinical analyses, strongly indicate that the recurrent NOTCH1, MYD88 and XPO1 mutations are oncogenic changes that contribute to the clinical evolution of the disease. To our knowledge, this is the first comprehensive analysis of CLL combining whole-genome sequencing with clinical characteristics and clinical outcomes. It highlights the usefulness of this approach for the identification of clinically relevant mutations in cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3322590/" 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/PMC3322590/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Puente, Xose S -- Pinyol, Magda -- Quesada, Victor -- Conde, Laura -- Ordonez, Gonzalo R -- Villamor, Neus -- Escaramis, Georgia -- Jares, Pedro -- Bea, Silvia -- Gonzalez-Diaz, Marcos -- Bassaganyas, Laia -- Baumann, Tycho -- Juan, Manel -- Lopez-Guerra, Monica -- Colomer, Dolors -- Tubio, Jose M C -- Lopez, Cristina -- Navarro, Alba -- Tornador, Cristian -- Aymerich, Marta -- Rozman, Maria -- Hernandez, Jesus M -- Puente, Diana A -- Freije, Jose M P -- Velasco, Gloria -- Gutierrez-Fernandez, Ana -- Costa, Dolors -- Carrio, Anna -- Guijarro, Sara -- Enjuanes, Anna -- Hernandez, Lluis -- Yague, Jordi -- Nicolas, Pilar -- Romeo-Casabona, Carlos M -- Himmelbauer, Heinz -- Castillo, Ester -- Dohm, Juliane C -- de Sanjose, Silvia -- Piris, Miguel A -- de Alava, Enrique -- San Miguel, Jesus -- Royo, Romina -- Gelpi, Josep L -- Torrents, David -- Orozco, Modesto -- Pisano, David G -- Valencia, Alfonso -- Guigo, Roderic -- Bayes, Monica -- Heath, Simon -- Gut, Marta -- Klatt, Peter -- Marshall, John -- Raine, Keiran -- Stebbings, Lucy A -- Futreal, P Andrew -- Stratton, Michael R -- Campbell, Peter J -- Gut, Ivo -- Lopez-Guillermo, Armando -- Estivill, Xavier -- Montserrat, Emili -- Lopez-Otin, Carlos -- Campo, Elias -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- England -- Nature. 2011 Jun 5;475(7354):101-5. doi: 10.1038/nature10113.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departamento de Bioquimica y Biologia Molecular, Instituto Universitario de Oncologia, Universidad de Oviedo, 33006 Oviedo, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21642962" target="_blank"〉PubMed〈/a〉

    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: All cancers are caused by somatic mutations; however, understanding of the biological processes generating these mutations is limited. The catalogue of somatic mutations from a cancer genome bears the signatures of the mutational processes that have been operative. Here we analysed 4,938,362 mutations from 7,042 cancers and extracted more than 20 distinct mutational signatures. Some are present in many cancer types, notably a signature attributed to the APOBEC family of cytidine deaminases, whereas others are confined to a single cancer class. Certain signatures are associated with age of the patient at cancer diagnosis, known mutagenic exposures or defects in DNA maintenance, but many are of cryptic origin. In addition to these genome-wide mutational signatures, hypermutation localized to small genomic regions, 'kataegis', is found in many cancer types. The results reveal the diversity of mutational processes underlying the development of cancer, with potential implications for understanding of cancer aetiology, prevention and therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3776390/" 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/PMC3776390/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alexandrov, Ludmil B -- Nik-Zainal, Serena -- Wedge, David C -- Aparicio, Samuel A J R -- Behjati, Sam -- Biankin, Andrew V -- Bignell, Graham R -- Bolli, Niccolo -- Borg, Ake -- Borresen-Dale, Anne-Lise -- Boyault, Sandrine -- Burkhardt, Birgit -- Butler, Adam P -- Caldas, Carlos -- Davies, Helen R -- Desmedt, Christine -- Eils, Roland -- Eyfjord, Jorunn Erla -- Foekens, John A -- Greaves, Mel -- Hosoda, Fumie -- Hutter, Barbara -- Ilicic, Tomislav -- Imbeaud, Sandrine -- Imielinski, Marcin -- Jager, Natalie -- Jones, David T W -- Jones, David -- Knappskog, Stian -- Kool, Marcel -- Lakhani, Sunil R -- Lopez-Otin, Carlos -- Martin, Sancha -- Munshi, Nikhil C -- Nakamura, Hiromi -- Northcott, Paul A -- Pajic, Marina -- Papaemmanuil, Elli -- Paradiso, Angelo -- Pearson, John V -- Puente, Xose S -- Raine, Keiran -- Ramakrishna, Manasa -- Richardson, Andrea L -- Richter, Julia -- Rosenstiel, Philip -- Schlesner, Matthias -- Schumacher, Ton N -- Span, Paul N -- Teague, Jon W -- Totoki, Yasushi -- Tutt, Andrew N J -- Valdes-Mas, Rafael -- van Buuren, Marit M -- van 't Veer, Laura -- Vincent-Salomon, Anne -- Waddell, Nicola -- Yates, Lucy R -- Australian Pancreatic Cancer Genome Initiative -- ICGC Breast Cancer Consortium -- ICGC MMML-Seq Consortium -- ICGC PedBrain -- Zucman-Rossi, Jessica -- Futreal, P Andrew -- McDermott, Ultan -- Lichter, Peter -- Meyerson, Matthew -- Grimmond, Sean M -- Siebert, Reiner -- Campo, Elias -- Shibata, Tatsuhiro -- Pfister, Stefan M -- Campbell, Peter J -- Stratton, Michael R -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- T32 CA009216/CA/NCI NIH HHS/ -- England -- Nature. 2013 Aug 22;500(7463):415-21. doi: 10.1038/nature12477.
