Application
Aflatoxin B1 is a carcinogenic compound that induces transversion of G to T at codon 249 of the p53 tumor suppressor gene. Aflatoxin B1 may be used as an internal standard when testing for aflatoxin contamination in food products.
Biochem/physiol Actions
Hepatocarcinogen. Food contaminant produced by Aspergillus flavus, a common soil fungus. Aflatoxin is biotransformed to genotoxic intermediates by P450 Phase I enzymes, mainly CYP3A4 via aflatoxin B1 3-hydroxylation. Detoxification depends on Phase II enzymes, such as Glutathione S-Transferase and AFB(1)-aldehyde reductase (AFAR).
