Ectopic expression of miR-22-3p suppresses the clonogenic capacity of TNBC cells in vitro
(A–F) Effects of overexpression of miR-22-3p on the colony-forming capacity of MDA-MB-231 (A and B), MDA-MB-436 (C and D), and BT-20 (E and F) cells. Left panels, representative culture dishes from a colony-formation assay. Right panels, the numbers of colonies formed by the cells transfected with miR-22-3p normalized according to the numbers of colonies formed by the cells transfected with control miRNA (Cont-miR). The data are presented as mean (±SD) (p < 0.05). ∗∗p < 0.01; ∗∗∗p < 0.001.
