Over-expression of miR-200b and miR-200c inhibited KGN cells proliferation. (a) and (b) The expression levels of miR-200b and miR-200c in KGN cells after transfection with miR-200b or miR-200c mimics. The expression level was detected by qRT-PCR and normalized against U6 (n = 3). (c) and (d) The proliferation ability of KGN cells transfected with miR-200b or miR-200c mimics was determined by CCK-8 assays (n = 6). The results were representative of three independent experiments. Statistical analysis was performed by Student’s t-test. Data were shown as the mean ± SD. ***P < 0.001
