Sasa borealis extract augments insulin signaling in C2C12 and HepG2 cells. C2C12 or HepG2 cells were treated with the extract (Ext) (40 µg/ml) for 24 h and then incubated with insulin (100 nM) for 1 h. Levels of phosphorylated IRS-1 (pIRS-1) was evaluated by western blotting. All experiments were performed three times, and representative figures are shown. The bars represent the relative densitometric values compared to untreated samples. The values are expressed as the mean ± SE (^*P < 0.05).
