Protein expression in liver. Western blot analysis of IRS-1 (a), PI3-K(b), and AKT (c) from liver of control and diabetic mice treated with saline (CTL SAL and STZ SAL) or with 600 mg/Kg of the crude extract of M. bella during 14 days (CTL EXT and STZ EXT). p-IRS-1, p-PI3-K, and P-AKT are the phosphorylated forms of the respective proteins. Data are . ∗ versus STZ SAL, @ versus CTL SAL, & versus CTL EXT, , . ANOVA followed by Tukey’s posttest.
