Overexpression of miR-93-5p enhances SCCHN migration and invasion. A, Representative fluorescence images were obtained under a fluorescence microscope. B, The expression of miR-93-5p was detected using qRT-PCR after transfection with a miR-93-5p-mimic. C, The migration ability of cells was examined using a scratch test, and the healing rate was calculated. D, Representative images from inserts were obtained for transwell invasion assays, and the invaded cells were quantified. Data are presented as the mean ± SD. Student's unpaired t-test, *, P <0.05; **, P < 0.01; ***, P < 0.001.
