In vivo exposure of B6C3F1 mice to the hepatotoxic chlorinated hydrocarbon, CCl4, suppresses T-cell-dependent humoral immune responses to sRBC. In the present studies, separation-crossover-reconstitution experiments with spleen cell subpopulations is

Research since 1983 has demonstrated that human hepatocytes can be isolated, cultured, and used for biological investigations, including studies of gene transcription and drug metabolism (1,2). In addition, the ability to cyropreserve hepatocytes has

Milk thistle extract is one of the most commonly used nontraditional therapies, particularly in Germany. Milk thistle is known to contain a number of flavonolignans. We evaluated the effect of silymarin, on the activity of various hepatic drug-metabo

In primary human and porcine hepatocyte cultures, we investigated the relationship between metabolism and cytotoxicity of troglitazone. Treatment of human hepatocytes for 2 h with 10, 20, 25, 35, and 50 microM troglitazone in protein-free medium resu

Troglitazone (TRO) is an insulin sensitizer used in the treatment of type II diabetes. TRO is known to increase the activity of cytochrome P-450 (CYP) 3A in vivo. We have investigated the effect of TRO on CYP3A protein content and the activity of CYP

We have previously reported that paclitaxel (Taxol) is a potent inducer of cytochrome P-450 (CYP) 3A protein and CYP3A mRNA in human hepatocyte cultures. Here we report that Taxol increased CYP3A-dependent testosterone 6beta-hydroxylation in intact h

The effect of ionic strength, assay constituents, alpha-naphthoflavone (aNF), terfenadine and testosterone on human CYP3A mediated midazolam (MDZ) 1'-hydroxylation (MDZ 1'-OH) and 4-hydroxylation (MDZ 4-OH) in vitro was examined. Increasing concentra

We have previously shown that rat liver epithelial cells (RLEC) transfected with and constitutively expressing transforming growth factor-alpha (TGF-alpha) have an enhanced mitogenic response to hepatocyte growth factor (HGF). In the study reported h

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
