Effect of intervene in SIRT-1 and combine with OA on p62, Beclin-1, LC3B, SIRT-1, PGC-1a, MFN1, MFF and COX-IV protein expression in HepG2 cells. HepG2 cells were treated with 1.5 mM OA for 48 h, following T6 (2 μM) or CAY (20 μM) 2 h. a The p62, Beclin-1 and LC3B protein expression was detected by Western blotting. b The same method was used to detect the SIRT-1, PGC-1a, MFN1, MFF and COX-IV protein expression. The bands were normalized using GAPDH. The images were quantified with ImageJ. Data are presented as the mean ± SD; *P < 0.05, **P < 0.01 compared with CON group; ^#P < 0.05, ^##P < 0.01 compared with OA group
