A. Evaluation of transfected melanoma cell with flow cytometry; over 75% of cells have been transfected by miR-30a-5p and scramble. B. Real-time PCR of miR-3a-5p in B16F10 melanoma cell lines after transfection with miR-30a-5p and scramble in comparison with control. C. MTT analysis showed that both miR-30a-5p and scramble have no obvious effects on viability of melanoma cells. D. Image and histogram of cell migration evaluated by Boyden chamber.*, P<0.05 compared to the control and scramble groups
