CUEDC1 decreases the motility and invasive properties of NSCLC cells. (A) CUEDC1 protein levels in different NSCLC cell lines and normal human bronchial epithelial cell line detected by western blotting. β-actin was used as an internal control. (B) CUEDC1 expression was confirmed by immunoblotting. CUEDC1 expression in H1299 and A549 cells was reduced markedly by shRNA1 interference. (C) Over-expression of CUEDC1 in H460 cells. CUEDC1 expression was determined using western blotting. (D) Wound-healing assays were used to investigate the migration of H1299 and A549 cells. P values were calculated using Student’s t-test. (E) Migration and invasion of H1299 and A549 cells (and their derivatives) were measured using transwell assays. P values were calculated using Student’s t-test. (F) Wound-healing assays were used to examine the migration of H460 cells. P values were calculated using Student’s t-test. (G) The migration and invasion of H460 cells (and their derivatives) were performed using transwell assays. The data are expressed as the mean ± SEM. P values were calculated using Student’s t-test; *P < 0.05; **P < 0.01; ***P < 0.001.
