Effects of metformin on fat accumulation, cell viability, and albumin production in HepG2 steatosis OOCs. HepG2 OOC cells were treated with vehicle (Veh, 1 mM NaOH), a mixture of oleic acid and palmitic acid (OA + PA, 0.5 mM in total) for 24 h to induce steatosis and then cultured in 10% or 0.5% FBS-containing media (Conditions A or B, respectively) with vehicle (serum-free medium) or metformin (0.01, 0.1, or 1 mM) for 6 days. (A and D) Quantitative analysis of Bodipy fluorescence. (B and E) WST-8-based viability assay. (C and F) Albumin amount (ratio) in conditioned medium. Data are presented as mean ± SEM and analyzed by one-way ANOVA (n = 3–5).
