Expression of sirtuin 1 (SIRT1) and acetylated high mobility group box 1 (Ac-HMGB1) in rat liver tissues. The protein expression of (A) sirtuin 1 (SIRT1) and (B) acetylated high mobility group box 1 (Ac-HMGB1) were assessed by Western blot in the sham, the liver resection, and the liver resection plus resveratrol-treated groups 72 h after surgery. * P<0.05, ** P<0.01, compared with the sham group; # P<0.05, ## P<0.01, compared with the liver resection group.
