Figure 8: Expression of insulin signaling proteins following different treatments. Western blotting was performed to assess the expression of p-PDK1, PDK1, p-Akt, Akt, p-IRS1, IRS1, and GLUT4. The values from densitometry were normalized to the level of GAPDH, respectively. * compared to the corresponding experimental control group, # compared to the corresponding VE deficiency group, and Δ compared to the corresponding radiation group.
