Figure 4. The effect of down-regulated ABI2 on NPC cells is similar to that of overexpressed EBV-miRNA-BART13-3p. (A) Western blot showed that knockdown of ABI2 by siRNA was effective. Downregulation of ABI2 caused decreased expression of E-cadherin and increased expression of Vimentin. (B, C) Transwell assay showed that siABI2 enhances migration and invasion of CNE1 and S26 cells. Right panel: quantification. Scale bar, 100μm. Error bars represent SEM. (*P<0.05; **P<0.01; ***P<0.001).
