A strong expression of miR-25 increases melanoma M14 cell migration. (A) M14 cells were transfected with NC or miR-25 plasmids. Cell migration was analyzed by a transwell assay where a 10% FBS culture medium was used as chemoattractant. (B) Statistical analysis of cell numbers after 0.1% crystal violet staining. Results represent data from three independent experiments. * P<0.05. P values were determined using Student’s t-tests.
