mSMG alleviated IR, promoted glycogen synthesis, and inhibited TNF-α/JNK1/IRS-2 pathway in liver of KK-Ay mice. A Representative H&E and Oil Red O staining images of liver sections (magnification 200×). B NAFLD activity score. C Positive area percentage of Oil Red O staining images. D Glycogen content in liver. E Glycogen synthase activity. F–L mSMG reduced the expression of TNF-α protein and the phosphorylation of JNK1 and IRS-2 (Ser388), and promoted the phosphorylation of Akt (Ser473) and GSK-3β (Ser9) as well as the expression of GLUT2 protein in liver. Data are expressed as mean ± SD (n = 6, *P < 0.05, **P < 0.01, ***P < 0.001)
