Identification of a ubiquitination-Target/Substrate-interaction domain of cytochrome P-450 (CYP) 2E1

Cytochrome P-450 (CYP) 2E1, the alcohol-inducible form of CYP, metabolizes a wide variety of endogenous substrates, therapeutic agents, protoxicants, and procarcinogens. CYP2E1 levels are post-transcriptionally elevated in response to certain xenobio

Xenobiotics that induce the cytochromes P450 also produce changes in rat hepatic sulfotransferase (SULT) gene expression. In the present study, male Sprague-Dawley rats were treated for 3 consecutive days with doses of phenobarbital (PB) that induce

It was previously demonstrated that treatment of primary cultured rat hepatocytes with lovastatin, an inhibitor of 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase, induced the mRNAs for several cytochromes P450 (P450s), including CYP2B1/2, CYP3A1/

Because hormones have been implicated in the molecular regulation of the sulfotransferase multigene family, the effects of glucocorticoid and antiglucocorticoid hormones on rat hepatic hydroxysteroid sulfotransferase-a and aryl sulfotransferase IV ge

Investigation of the posttranscriptional mechanisms involved in the xenobiotic-mediated enhancement of cytochrome P450 2E1 (CYP2E1) expression has been limited by a lack of a functional primary hepatocyte cell culture system. We examined the effects

We previously demonstrated that induction of hepatic cytochrome P4503A (CYP3A) immunoreactive protein is a response in rats, but not rabbits, treated with the antiglucocorticoid, pregnenolone 16 alpha-carbonitrile and in rabbits, but not rats, treate

Poly(A) tail length is important in the stability and translation of mRNA. We describe procedures for the rapid and reproducible analysis of poly(A) tail length of a single mRNA species contained in a sample of total hepatic RNA. A short 3' fragment

Freshly isolated rat hepatocytes rapidly lose their cytochrome P450 (P450) proteins and mRNAs, with no evidence of subsequent restoration, after placement into traditional systems of primary culture on type I collagen. We examined the patterns of exp

Cytochromes P450b and P450e (IIB1 and IIB2, respectively) are two remarkably similar microsomal hemoproteins whose inductions in rat liver are generally believed to be coordinately controlled by such xenobiotics as phenobarbital. To critically examin

Phenobarbital induces cytochromes P450 (P450s) of not only the class IIB gene subfamily (i.e., P450b and P450e) but also the class IIIA gene subfamily (P450p and P450pcn2). To determine whether coinduction of these structurally dissimilar gene produc
