Chronic ethanol feeding decreased GSH/GSSG ratio in high density microsomes isolated from adipose tissue, associated with an increase in CYP2E1 expression. Rats were allowed free access to an ethanol-containing diet or pair-fed a control diet for 4 weeks. Epididymal adipose tissue was homogenized, high density microsomes were isolated and lysed. (A) GSH/GSSG, (B) GSH, (C) GSSG, and (D) total glutathione were determined by a HPLC-based method as described in methods. n=6. (E) Immunoreactive CYP2E1 was measured by western blot in high density microsome lysates. n=4–5. Images are representative of 4–5 rats per treatment group. Values represent means ± SEM. Values with an asterisk are significantly different from each other, p< 0.05.
