The effects of rutaecarpine on IRS-1-PI3K-Akt insulin receptor mediated pathway were analyzed by Western blot with liver tissues. The 7 weeks treatment of rutaecarpine (25 mg/kg) or metformin (250 mg/kg) inhibited IRS-1 phosphorylation (A); promoted expression of PI3K p85 (B); and enhanced phosphorylation of Akt (C). The protein expressions were expressed as mean grey scale of corresponding bands in bar graph. Values are mean±SD, n=6 in each group. bP<0.05, cP<0.01 vs NC; eP<0.05, fP<0.01 vs F/SC.
