Figure 3. GP restored the activity of AKT/GSK-3β signaling axis. (A) Western blots for AKT/GSK-3β pathway-related proteins. (B–D) Quantification of the relative protein levels of p-AKT (308), p-AKT (473) and s9-GSK-3β after normalization to the β-actin signal. Data represent mean ± SEM, p-value significance is calculated from one-way ANOVA, n = 3. *P < 0.05, **P < 0.01. Abbreviation: NS: no significance.
