Project Description
PhIP is a carcinogen formed from a chemical reaction in meat cooked at high temperature, causing colon cancer in rats through conversion to its hydroxylamine metabolite (NHOH-PhIP). This study examined the cellular mechanism by which NHOH-PhIP can be detoxifed by involvement of cytochrome b5 reductase (b5R) and cytochrome b5 (cyt b5), while single nucleotide polymorphisms (SNPs) account for variability in response.
