Effect of KPE on the PI3K/AKT pathway. Hs68 cells were pretreated with KPE (1–10 μg/ml) or resveratrol (10 μM) for 24 h. After 2 h of H2O2 exposure, the cells were cultured for an additional 24 h. Protein expression of associated markers in the PI3K/AKT signaling pathway was evaluated via western blotting. The effect of KPE on (a) PI3K and AKT activation and (b) the levels of mTOR and FoxO3a are shown. α-Tubulin was used as the loading control.
