SD (spraguedawley)rat( ) hepatocytes were treated with clofibrate and the express levels of its
(pregnane X receptor) and (cytochrome P450 3A1) were determined by Western blot and RTPCR. The results were as
follows: Clofibrate markedly increased the expression of , and the induction was abolished by actinomycin D, an inhibitor for
mRNA synthesis.No induction of by clofibrate was tested, pregnenolone 16 carbonitrile (PCN) alone markedly induced

the expression of ,but cotreatmentwith clofibrate enhanced the induction.Clofibrate is one ofperoxisome proliferators,the
