- The MUTYH gene is known to be associated with Familial adenomatous polyposis (MAP: MUTYH -associated polyposis), and encodes a DNA repair protein that suppresses mutations caused by oxidative stress in mammalian cells. MUTYH is involved not only in the suppression of mutations but also in the cell death induced by oxidative stress. In this study, I investigate the role of MUTYH associated with mismatch repair proteins in the induction of cell death caused by oxidative stress.
- We developed an experimental system for oxidative stress-inducing mutagenesis and carcinogenesis in the intestine of mice. In oder to identify the common genes mutated in the adenomas/carcinomas induced by using this system, we analyze the genomes of adenomas/carcinomas induced in the same animals.
