NGGAs modulate epithelial-to-mesenchymal transition (EMT) markers and inhibit cell migration and invasion. (A) VNPP414 (414) and VNPP433-3β (433) induce expression of E-cadherin and decreased expressions of N-cadherin, MMP2, MMP9, and Slug. (B) VNPP414 (414) and VNPP433-3β (433) decreased expressions of β-catenin, CD44, EZH2, BMI-1, and Nanog. (C) VNPP414 and VNPP433-3β inhibit PC cells migration. (D) VNPP414 and VNPP433-3β inhibit PC cells invasion. (E) Quantifications of inhibition of cell migration and invasion by VNPP414 and VNPP433-3β. Note: the numbers in parentheses in Figure 5A,B are concentrations of the agents in µM.
