[Heterocyclic aromatic amines, food-derived mutagens: metabolism and relevance to cancer susceptibility].

Abstract excerpt

It is estimated that diet contributes to as much as one-third of cancer incidents. Heterocyclic aromatic amines (HCAs) are well-known mutagens/carcinogens found in thermal-processed meat and fish. HCAs require metabolic activation to exert their carcinogenic potential. First step in HCAs activation--the generation of N-hydroxy-HCA derivatives--is catalyzed by cytochrome P450, mainly isoenzyme CYP1A2. Further...
