Effect of flazin on lipid droplet (LD) accumulation. (A) Representative photographs of oil red O staining. (B) Neutral lipid content. PA, PA-F40 and PA-F80 groups are presented as relative amount to PA group; OA, OA-F40 and OA-F80 groups are presented as relative amount to OA group. (C) Average LD size. (D) LD number. PA, 200 μM palmitic acid; PA-F40, 200 μM palmitic acid + 40 μM flazin; PA-F80, 200 μM palmitic acid + 80 μM flazin; OA, 200 μM oleic acid; OA-F40, 200 μM oleic acid + 40 μM flazin; OA-F80, 200 μM oleic acid + 80 μM flazin. # p < 0.05, ### p < 0.001 vs. PA group, $$ p < 0.01, $$$ p < 0.001 vs. OA group (n = 3).
