Mrp2 protein levels were significantly increased by all 3 PXR ligands/CYP3A inducers (pregnenolone-16alpha-carbonitrile [PCN], spironolactone [SP], and dexamethasone [DEX]) and by both ARE/EpRE ligands (ethoxyquin [EQ] and oltipraz [OPZ]).

Consumption of dietary EQ produced the expression of CYP3A, glutathione S-transferase (GST), and uridine diphosphate glucuronosyl-transferase (UDPGT) mRNA during the depuration period.

However, the decrease in biotransformation rate results in the accumulation of EQ metabolites, high concentration of which was postulated to alter translation and post-translational modification of CYP3A, GST and UDPGT at feeding day 14 and 42, with subsequent decreases in the biotransformation of consumed EQ.

The present work tests the generally held assumption that xenobiotic metabolism in the TG:AC and p53+/- mouse is not inherently different from that of the respective wild type, the FVB/N and C57BL/6 mouse, by comparing each genotype's ability to metabolize benzene, ethoxyquin, or methacrylonitrile.
Further, expression of CYP1A2, CYP2E1, CYP3A, and GST-alpha in liver of naive genetically altered mice was similar to that of corresponding wild-type mice.
