Abstract excerpt
BACKGROUND: In rat colon tumors induced by the cooked food mutagens 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) and 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), ras and p53 alterations are rarely detected. To investigate the roles of the APC gene and microsatellite instability (MI) in PhIP-induced colon carcinogenesis, mutations of the APC gene and alterations of microsatellites were examined....
