Male Wistar rats have been pretreated with either clofibrate or diethylhexylphthalate and the dose-dependency of induction of the microsomal, cytochrome P-452-driven fatty acid hydroxylase and peroxisomal fatty acid β-oxidation system investigated. Both clofibrate and DEHP specifically induced ...detailed
The gene coding for the clofibrate-induced cytochrome P-452 has been isolated from a cDNA library and a full-length cDNA clone sequenced. The sequence was identical with that reported by Hardwick et al. [(1987) J. Biol. Chem. 262, 801–810] apart from the presence of an additional 75 nucleotides...detailed
Hepatocyte nodules, a characteristic early step in the development of liver cancer in rats, has a distinctive resistance phenotype including a large decrease in total cytochromes P-450 and in two isozymes induced by phenobarbital and two by 3-methylcholanthrene. In this study, it has been observ...detailed
The influence of four hypolipidaemic drugs (clofibrate, WY-14,643, clobuzarit and bezafibrate) on hepatic cytochrome P-450 and fatty acid metabolism in male rat liver microsomes has been investigated. All of the hypolipidaemic drugs tested significantly induced the hydroxylation of lauric acid a...detailed
Eight structurally diverse hypolipidaemic agents have been examined for their ability to induce the microsomal cytochrome P-452-dependent fatty acid hydroxylase system and the enzymes of peroxisomal β-oxidation in rat liver. Using a specific ELISA method, we have shown that the cytochrome P-452...detailed
We have examined the ability of a commercial mixture of polychlorinated biphenyls (Aroclor 1254) to induce hepatic cytochrome P-452-linked enzyme activities in rat and pigeon liver five days after its intraperitoneal injection. The results provide evidence that, at the doses used, Aroclor 1254 i...detailed
