WT, ALDH2−/−, and ALDH2−/−STAT3Hep−/− mice were fed an ethanol diet for 10 days, followed by a single gavage of ethanol. The mice were euthanized 9 h after gavage. (A) Western blot analysis. (B) Serum ALT levels. (C) Hepatic triglyceride (TG) levels. (D) Representative hematoxylin and eosin (H&E) staining and Oil Red O staining of liver tissues. (E) The hepatic expression of cytokines was measured using real-time PCR analyses. The values in panels B, C, E represent means ± SD. (n=6 WT, n=4 ALDH2−/− or ALDH2−/−STAT3Hep−/−). *P < 0.05.
