    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: Congenital heart disease (CHD) is the most frequent birth defect, affecting 0.8% of live births. Many cases occur sporadically and impair reproductive fitness, suggesting a role for de novo mutations. Here we compare the incidence of de novo mutations in 362 severe CHD cases and 264 controls by analysing exome sequencing of parent-offspring trios. CHD cases show a significant excess of protein-altering de novo mutations in genes expressed in the developing heart, with an odds ratio of 7.5 for damaging (premature termination, frameshift, splice site) mutations. Similar odds ratios are seen across the main classes of severe CHD. We find a marked excess of de novo mutations in genes involved in the production, removal or reading of histone 3 lysine 4 (H3K4) methylation, or ubiquitination of H2BK120, which is required for H3K4 methylation. There are also two de novo mutations in SMAD2, which regulates H3K27 methylation in the embryonic left-right organizer. The combination of both activating (H3K4 methylation) and inactivating (H3K27 methylation) chromatin marks characterizes 'poised' promoters and enhancers, which regulate expression of key developmental genes. These findings implicate de novo point mutations in several hundreds of genes that collectively contribute to approximately 10% of severe CHD.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3706629/" 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/PMC3706629/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaidi, Samir -- Choi, Murim -- Wakimoto, Hiroko -- Ma, Lijiang -- Jiang, Jianming -- Overton, John D -- Romano-Adesman, Angela -- Bjornson, Robert D -- Breitbart, Roger E -- Brown, Kerry K -- Carriero, Nicholas J -- Cheung, Yee Him -- Deanfield, John -- DePalma, Steve -- Fakhro, Khalid A -- Glessner, Joseph -- Hakonarson, Hakon -- Italia, Michael J -- Kaltman, Jonathan R -- Kaski, Juan -- Kim, Richard -- Kline, Jennie K -- Lee, Teresa -- Leipzig, Jeremy -- Lopez, Alexander -- Mane, Shrikant M -- Mitchell, Laura E -- Newburger, Jane W -- Parfenov, Michael -- Pe'er, Itsik -- Porter, George -- Roberts, Amy E -- Sachidanandam, Ravi -- Sanders, Stephan J -- Seiden, Howard S -- State, Mathew W -- Subramanian, Sailakshmi -- Tikhonova, Irina R -- Wang, Wei -- Warburton, Dorothy -- White, Peter S -- Williams, Ismee A -- Zhao, Hongyu -- Seidman, Jonathan G -- Brueckner, Martina -- Chung, Wendy K -- Gelb, Bruce D -- Goldmuntz, Elizabeth -- Seidman, Christine E -- Lifton, Richard P -- 5U54HG006504/HG/NHGRI NIH HHS/ -- F30 HL123238/HL/NHLBI NIH HHS/ -- P30 HD018655/HD/NICHD NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- U01 HG006546/HG/NHGRI NIH HHS/ -- U01 HL098123/HL/NHLBI NIH HHS/ -- U01 HL098147/HL/NHLBI NIH HHS/ -- U01 HL098153/HL/NHLBI NIH HHS/ -- U01 HL098162/HL/NHLBI NIH HHS/ -- U01 HL098163/HL/NHLBI NIH HHS/ -- U01-HL098123/HL/NHLBI NIH HHS/ -- U01-HL098147/HL/NHLBI NIH HHS/ -- U01-HL098153/HL/NHLBI NIH HHS/ -- U01-HL098162/HL/NHLBI NIH HHS/ -- U01-HL098163/HL/NHLBI NIH HHS/ -- U01-HL098188/HL/NHLBI NIH HHS/ -- U54 HG006504/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jun 13;498(7453):220-3. doi: 10.1038/nature12141.

    Notes: A method is described for the determination of 1-nitropyrene in a diesel exhaust particulate extract by thin-layer chromatography. 1-Nitropyrene is determined as 1-aminopyrene after prechromatographic reduction and isolation by solvent partition. The fluorescence response of 1-aminopyrene is approximately 1000-fold greater than that of 1-nitropyrene. The poor fluorescence stability of 1-aminopyrene on silica gel plates prevents in situ detection by scanning densitometry unless the plates are impregnated with a mixture of 2,6-di-tert-butyl-4-methylphenol and Fomblin H-Vac. A linear response from 1 to 150 ng of 1-aminopyrene and a detection limit of 1.0 ng were obtained using the impregnated plates. For fourteen samples of a diesel exhaust particulate extract the concentration of 1-nitropyrene was determined to be 165 μg/g with an RSD = 9.0%. No significant interferences were observed from other nitro- or aminopolycyclic aromatic compounds present in the extract.
