Expression of CYP1A in liver of A/Sn and CC57BR mice differing in sensitivity to hepatocarcinogenesis induced by o-aminoazotoluene.

The induction of P450 cytochromes Cyp1a1 and Cyp1a2 in the liver of male mice differing in sensitivity to the carcinogenic effect of o-aminoazotoluene (OAT) has been studied. The level of Cyp1a1 and Cyp1a2 mRNA was assayed by quantitative competitive polymerase chain reaction (PCR). In both OAT-treated strains, the level of Cyp1a1 mRNA increased more than… CONTINUE READING
