Figure 5. As₂O₃ activates the AKT/GSK-3β/Snail pathway.

(a) HAECs were treated with or without As₂O₃, and the expression of Snail and the activation of AKT and GSK-3β were determined by western blotting. (b) Relative mRNA expression level of AKT, GSK-3β and Snail in different groups. **p < 0.01 vs. untreated condition (0 μmol/l As₂O₃). Data are expressed as mean ± SEM, n = 3–5.
