Molecular Mechanisms of Cytochrome P-450 Induction by Xenobiotics: An Expanded Role for Nuclear Hormone Receptors

Abstract
Drug exposures can lead to an increased expression of specific cytochrome P-450 proteins (P-450s) as well as of phase II drug-metabolizing enzymes that can greatly augment the metabolism and clearance of therapeutic drugs. Animal models have been used to estimate the potential of drugs to induce P-
