CYP2E1 and oxidant stress in alcoholic and non-alcoholic fatty liver disease.
Study Goal
The researchers aimed to summarize the role of CYP2E1 in alcoholic and non-alcoholic fatty liver diseases, particularly focusing on its contribution to ROS generation and disease progression.
Results Summary
The abstract highlights that high-fat diet contributes to fatty liver diseases by inducing oxidant stress and ROS generation, with CYP2E1 playing a critical role in this process. It also notes that alcohol further induces CYP2E1, exacerbating liver injury.

Alcoholic (ALD) and non-alcoholic fatty liver diseases (NAFLD) are clinical conditions leading to hepatocellular injury and inflammation resulting from alcohol consumption, high fat diet, obesity and diabetes, among others. Oxidant stress is a major contributing factor to the pathogenesis of ALD and NAFLD. Multiple studies have shown that generation of reactive oxygen species (ROS) is key for the progression of fatty liver to steatohepatitis. Cytochrome P450 2E1 (CYP2E1) plays a critical role in ROS generation and CYP2E1 is also induced by alcohol itself. This review summarizes the role of CYP2E1 in ALD and NAFLD.
