Tissue-specific induction of cytochrome P-450s (CYP) followed by increased in situ bioactivation may contribute to chemical-induced site-specific toxicity. In rats, methacrylonitrile (MAN) is metabolized by cytochrome P-450 2E1 (CYP2E1) to acetone, which is eliminated along with parent MAN in breath.
