Figure 4. Effect of miR-424-5p on the proliferation, invasion, and viability of OSCC cells induced by KDR overexpression. (A) KDR expression in CAL27 cells with mimic-nc or mimic-miR-424 plasmid. (B) Immigration of CAL27 cells determined by the wound healing assay (n = 3 in each group). (C) The MTT assay was used to determine the cell viability at 24 h, 48 h, and 72 h. (n = 3 in each group). (D) Invasion of CAL27 cells determined by the wound healing assay (n = 3 in each group). *P < 0.05 **P < 0.01.
