Abstract
The loss of cytochrome P450 (CYP)-dependent activity continues to be a problem in the use of cultured hepatocytes in xenobiotic toxicity studies. It has been reported that the inclusion of pyruvate and various hormones in the culture medium improves the maintenance of various hepatic functions, including that of CYP2C11 mRNA expression. We have studied this further, by investigating the effects of the addition of pyruvate and hormones on various CYP-dependent enzyme activities and on the CYP-dependent toxicity of precocene II in rat hepatocyte cultures. No beneficial effects of this medium supplementation could be demonstrated.
