miR-4262 mimic transfection promoted proliferation and invasion of MDA-MB-231 and MCF-7 breast cancer cell lines. The negative control mimic (NC) or miR-4262 mimic was transfected into MDA-MB-231 and MCF-7 human breast cancer cell lines. After incubation for 48 h, miR-4262 expression was detected with real-time qPCR, cell proliferation was detected with the CCK-8 method, and cell invasion was detected with the Transwell invasion assay. (A) miR-4262 expression was increased greatly by the miR-4262 mimic transfection. (B, C) The miR-4262 mimic significantly promoted the proliferation of MDA-MB-231 and MCF-7 cells. (D) The miR-4262 mimic significantly enhanced the invasion of MDA-MB-231 and MCF-7 cells. *p < 0.05, *p < 0.01 versus NC.
