Figure 6. Overexpression of miR-31-5p attenuates the oncogenic effects of circ-BPTF in BCa cells. (A, B) The migratory ability enhanced by overexpression of circ-BPTF was attenuated after co-transfection with miR-31-5p mimics. (C, D) The proliferative ability enhanced by overexpression of circ-BPTF was also attenuated after co-transfection with miR-31-5p mimics. Data indicate means ± SEM. *P<0.05, **P<0.01.
