Figure 3 Reelin promotes EMT in NSCLC cells. (A) Cell morphological observations after Reelin overexpression (A549-NC versus A549/Reelin) in A549 cells and Reelin knockdown in A549/DDP cells (A549/DDP si-NC versus A549/DDP si-Reelin). (B–D) E-cadherin and N-cadherin expressions were evaluated by western blotting and immunofluorescence in A549 cells transfected with the Reelin expression vector and A549/DDP cells transfected with Reelin si-RNA. (E, F) Cell migration was measured by Transwell migration assays. * P<0.05, ** P<0.01.
