Abstract
This review summarizes data on expression level and localization, structure and functional properties of
cytochrome P4502E1 (CYP2E1). Induction of CYP2E1 synthesis and activity by compounds with various
chemical structures and under certain pathophysiological states is considered. Special emphasis is placed
on CYP2E1 expression inhibitors. The latest data on CYP2E1 expression regulation and degradation
mechanisms are analyze
Keywords: cytochrome P4502E1 (CYP2E1), expression, inductors and inhibitors, expression regulation, oxidative metabolism of ethanol
