The systematic translation of cancer genomic data into knowledge of tumour biology and therapeutic possibilities remains challenging. Such efforts should be greatly aided by robust preclinical model systems that reflect the genomic diversity of human cancers and for which detailed genetic and pharmacological annotation is available. Here we describe the Cancer Cell Line Encyclopedia (CCLE): a compilation of gene expression, chromosomal copy number and massively parallel sequencing data from 947 human cancer cell lines. When coupled with pharmacological profiles for 24 anticancer drugs across 479 of the cell lines, this collection allowed identification of genetic, lineage, and gene-expression-based predictors of drug sensitivity. In addition to known predictors, we found that plasma cell lineage correlated with sensitivity to IGF1 receptor inhibitors; AHR expression was associated with MEK inhibitor efficacy in NRAS-mutant lines; and SLFN11 expression predicted sensitivity to topoisomerase inhibitors. Together, our results indicate that large, annotated cell-line collections may help to enable preclinical stratification schemata for anticancer agents. The generation of genetic predictions of drug response in the preclinical setting and their incorporation into cancer clinical trial design could speed the emergence of 'personalized' therapeutic regimens. 相似文献

To newly identify loci for age at natural menopause, we carried out a meta-analysis of 22 genome-wide association studies (GWAS) in 38,968 women of European descent, with replication in up to 14,435 women. In addition to four known loci, we identified 13 loci newly associated with age at natural menopause (at P < 5 × 10(-8)). Candidate genes located at these newly associated loci include genes implicated in DNA repair (EXO1, HELQ, UIMC1, FAM175A, FANCI, TLK1, POLG and PRIM1) and immune function (IL11, NLRP11 and PRRC2A (also known as BAT2)). Gene-set enrichment pathway analyses using the full GWAS data set identified exoDNase, NF-κB signaling and mitochondrial dysfunction as biological processes related to timing of menopause. 相似文献

Chronic kidney disease (CKD), impairment of kidney function, is a serious public health problem, and the assessment of genetic factors influencing kidney function has substantial clinical relevance. Here, we report a meta-analysis of genome-wide association studies for kidney function-related traits, including 71,149 east Asian individuals from 18 studies in 11 population-, hospital- or family-based cohorts, conducted as part of the Asian Genetic Epidemiology Network (AGEN). Our meta-analysis identified 17 loci newly associated with kidney function-related traits, including the concentrations of blood urea nitrogen, uric acid and serum creatinine and estimated glomerular filtration rate based on serum creatinine levels (eGFRcrea) (P < 5.0 × 10(-8)). We further examined these loci with in silico replication in individuals of European ancestry from the KidneyGen, CKDGen and GUGC consortia, including a combined total of ~110,347 individuals. We identify pleiotropic associations among these loci with kidney function-related traits and risk of CKD. These findings provide new insights into the genetics of kidney function. 相似文献

Primary sclerosing cholangitis (PSC) is a chronic bile duct disease affecting 2.4-7.5% of individuals with inflammatory bowel disease. We performed a genome-wide association analysis of 2,466,182 SNPs in 715 individuals with PSC and 2,962 controls, followed by replication in 1,025 PSC cases and 2,174 controls. We detected non-HLA associations at rs3197999 in MST1 and rs6720394 near BCL2L11 (combined P = 1.1 × 10?1? and P = 4.1 × 10??, respectively). 相似文献

Catalysis of guanine nucleotide exchange on the CDC42Hs protein by the dbl oncogene product 总被引:49,自引:0,他引:49
THE superfamily of low molecular mass GTP-binding proteins, for which the ras proteins are prototypes, has been implicated in the regulation of diverse biological activities including protein trafficking, secretion, and cell growth and differentiation. One member of this family, CDC42Hs (originally referred to as Gp or G25K), seems to be the human homologue of the Saccharomyces cerevisiae cell-division-cycle protein, CDC42Sc. A second S. cerevisiae protein, CDC24, which is known from complementation studies to act with CDC42Sc to regulate the development of normal cell shape and the selection of nonrandom budding sites in yeast, contains a region with sequence similarity to the dbl oncogene product. Here we show that dbl specifically catalyses the dissociation of GDP from CDC42Hs and thereby qualifies as a highly selective guanine nucleotide exchange factor for the GTP-binding protein. Although guanine nucleotide exchange activities have been previously described for other members of the Ras-related GTP-binding protein family, this is the first demonstration, to our knowledge, of the involvement of a human oncogenic protein in catalysing exchange activity. 相似文献

Zusammenfassung Die Aktivität der Sarcosinedehydrogenase in Lebermitochondrien 7tägiger Ratten ist um 50% kleiner als in adulten Tieren. Dieser Unterschied ist nicht durch das Elektrontransportflavoprotein limitiert und kann auch nicht durch eine Änderung in dem relativen Wert der löslichen Proteine in den Mitochondrien erklärt werden. 相似文献
