In order to identify the gene(s) commonly mutated during the process of oxidative stress-induced carcinogenesis, we performed genome-wide mutational analysis of the small intestinal tumors induced by oxidative stress in Mutyh gene deficient mice. We searched the commonly mutated gene(s) found in independent tumor tissues. Among three independent tumors, mutations resulting in amino acid substitution were detected in 105, 100, and 67 cases, respectively, with 6 genes in all 3 tumors, 9 genes in 2 of 3 tumors in common.We also performed retrovirus-mediated gene-trap mutagenesis and isolated several clones exhibiting an increased resistance to the killing effect of DNA-damaging agents. By the analyses of the clones, we identified Mapo1 and Hmga as new genes involved in the induction of apoptosis triggered by DNA damage.
