pubmed:abstractText |
A monkey cytochrome P-450IA1 cDNA (MKah1) was transfected into Chinese hamster CHL cells using a vector containing the SR alpha promoter, and sublines stably expressing P-450IA1 were established. The cells showed 25-fold higher sensitivity to the cytotoxic effect of aflatoxin B1 than the parental CHL cells. This hypersensitivity was almost completely suppressed by alpha-naphthoflavone, which is a known specific inhibitor of P-450IA. The cells expressing P-450IA1, but not CHL cells, showed a positive response to aflatoxin B1 in an assay for mutagenicity at the HGPRT locus.
