AQP3 regulates EMT via the PI3K/AKT/Snail pathway. SGC7901and MGC803 cells were treated with control siRNA, RNAi AQP3 and EGF, with or without a PI3K/AKT inhibitor. Proteins were analyzed by western blotting assay. GAPDH was used as an internal control. The relative accumulation of proteins was compared with the untreated group.
