MiR-203a-3p inhibition increased NPC cell proliferation, invasion and migration in vitro. CNE2 and SUNE1 cells were transfected with miR-203a-3p inhibitor (Anti-miR-203a, 100 nM), negative control (Anti-Ctrl, 100 nM) or PBS (Blank). Expression of miR-203a-3p after transfection a. MTT assays were performed in CNE2 and SUNE1 cells on one to five days after transfection b. Colony formation was performed by crystal violet staining in CNE2 and SUNE1 cells c. Representative images for wound healing assay d and transwell invasion assays e. The cell counting results of transwell migration e and invasion assays f. ** P < 0.01 compared with Anti-Ctrl or Blank groups. The results are representative of at least three independent experiments. Statistical analysis was performed using one way ANOVA
