Figure 5. miR-874-3p inhibits proliferation, migration and invasion of breast cancer cells. MCF-7 and BT549 cells were transduced with miR-874-3p mimic NC or miR-874-3p mimics. (A, B) Cell proliferation was detected with CCK8 assay (A) and EDU assay (B). (C, D) Transwell assay was used to detect cell migration and invasion ability. The data are presented as the mean ± S.D. *P < 0.05, **P < 0.01.
