Biological functions of miR-28-3p and miR-28-5p in cell viability and cell growth in vitro. Cell viability was determined by CCK-8 assay (a, b). The effect of miR-28-3p/-5p on tumorigenic capability of the NPC cells was measured by the colony-forming assay (c), Number of colonies were counted at the 7th day after transfection with mimics (d) and inhibitors (e) of miR-28-3p/-5p. The data are representative of three repeats. *P < 0.05, ***P < 0.001, vs negative control
