Figure 2. EBV-miR-BART13-3p induces EMT of NPC cells. (A) Cell morphological changes after transient transfection of BART13-3p in CNE1 and S26 cells. Scale bar, 100μm. Western blot (B), immunofluorescence (C) and immunohistochemistry (D) all showed that BART13-3p overexpression contributes to decrease of E-cadherin and increase of Vimentin in NPC cells or in NPC tumor specimens. Scale bar, 20μm (C) and 100μm (D). (*P<0.05; **P<0.01; ***P<0.001).
