Global Cyp2e1 KO (Cyp2e1−/−) strain

The Cyp2e1 KOstrain was developed and characterized by Gonzalez’s lab at NCI and backcrossed into a B6 background by Song at NIAAA (1). The Cyp2e1 KOmice appear normal but are less sensitive to acetaminophen-induced hepatotoxicities (1) and protected from ethanol-induced fatty liver and oxidative damage (2). These findings support a major role for CYP2E1 in mediating toxicant-induced liver injuries. This mouse strain represents an important animal model for the study of CYP2E1 enzyme in ethanol-associated tissue damage.
