Arazyme reduced intracellular lipid accumulation in PA-induced HepG2 cells. (A,B) Viability of arazyme in HepG2 cells treated with arazyme. Cells were incubated with the indicated concentrations of arazyme for 24 h without (A) or with (B) PA. Oil-red O staining images (C, × 200 magnification) and intracellular TG contents (D). (E,F) Protein expression levels of SREBP-1 and FAS were detected by Western blotting. Data are presented as means ± SD (n = 3). #
p < 0.05, ##
p < 0.01 vs. cells treated with medium only; * p < 0.05, ** p < 0.01 vs. cells treated with PA only by Student’s t-tests.
