Induction of cytochrome P450 2E1 during chronic ethanol exposure occurs via transcription of the CYP 2E1 gene when blood alcohol concentrations are high.


Induction of cytochrome P450 CYP 2E1 during chronic ethanol exposure in rats has been reported by our laboratory to occur by a complex two step process. The first step occurs at relatively low blood alcohol concentrations and involves increases in CYP 2E1-dependent activities and apoprotein levels with no increases in steady-state mRNA encoding CYP 2E1.
