Effect of insulin on hepcidin expression in HepG2 cells. Effect of insulin on hepcidin expression in HepG2 cells. A and B: HepG2 cells were treated with 100 nmol/L insulin for 4, 8, 12, and 24 h separately or insulin at the indicated concentrations of 0, 0.1, 1, 10, and 100 nmol/L for 24 h. Hepcidin protein (A) and mRNA (B) expression were determined by WB and real-time quantitative PCR, respectively. Data are expressed as means ± SEM, determined in three independent experiments. One-way ANOVA, followed by LSD t and SNK post hoc test, was performed to analyze difference between the groups. *Significantly different from control group, P < 0.05; **P < 0.01; ***P < 0.001; §significantly different compared with control group, P = 0.056.
