Effects of SalA on lipid accumulation, oxidative stress and inflammation in PA-treated HepG2 cells.
HepG2 cells were pretreated with SalA (20 μM) for 6 h before exposure to PA (0.5 mM) for another 24 h. (A) Intracellular lipid accumulation was measured by Nile Red staining. (B) Cell supernatant H2O2 levels. (C) The levels of TNF-α and IL-6 in the culture medium were measured by ELISA. (D) Intracellular ROS levels were measured using the fluorescent probe DCFH-DA. The results are presented as the means ± SD (n = 8). **P < 0.01 vs. the control group; ##P < 0.01 vs. the PA-treated group. The images were obtained using fluorescence microscopy (400×). (A) Control group; (B) PA group; (C) PA group pretreated with 20 μM SalA.
