“Identification of cancer drivers across tumor types”

Thousands of tumor genomes/exomes are being sequenced as part of the International Cancer Genome Consortium (ICGC), The Cancer Genome Atlas (TCGA) and other initiatives. This opens the possibility to have, for the first time, a comprehensive picture of mutations, genes and pathways involved in the cancer phenotype across tumor types.

We have developed computational methods able to identify signals of positive selection in the pattern of tumor somatic mutations, which point to genes and pathways directly involved in the development of the tumors.

We have applied these approaches to 3025 tumors from 12 different cancer types of the TCGA Pan-Cancer project, identifying 291 high-confidence cancer driver genes acting on those tumors (Tamborero et al 2013).

We have also developed IntOGen-mutations (http://www.intogen.org/mutations), a novel web platform for cancer genomes interpretations, which analyses not only TCGA pan-cancer data but all mutation data from ICGC and other initiatives. The resource allows users to identify driver mutations, genes and pathways acting on more than 6000 tumors originated in 17 different cancer sites and to analyze newly sequence tumor genomes.

Among the novel cancer drivers identified there are chromatin regulatory factors and splicing factors, which are emerging as important genes in cancer development and are regarded as interesting candidates for novel targets for cancer treatment.

In my talk I will summarize all these recent findings.
