摘要: To address the biological heterogeneity of lung cancer, we studied 199 adenocarcinomas by integrating genome-wide data on copy number alterations and gene expression with full annotation for major known somatic mutations in this cancer. This showed non-random patterns significantly linked to EGFR KRAS mutation status distinct clinical outcomes, led discovery a striking association underexpression DUSP4, within broad region frequent single-copy loss 8p. DUSP4 is involved negative feedback control signaling, provide functional validation its role as growth suppressor EGFR-mutant adenocarcinoma. also associates p16/CDKN2A deletion defines subset cancer patients. Another novel observation that reciprocal relationship between LKB1 mutations. These results highlight power integrated genomics identify candidate driver genes recurrent regions alteration delineate oncogenetic pathways genetically complex common epithelial cancers.
