Overexpression of miR-124 suppressed ovarian cancer cell migration and invasion. (A) OCVAR3 and (B) SKOV3 cells transfected or not with miR-124 mimics or scramble for 24 h. Wounds were made (magnification, ×200). (C) The OCVAR3 cells were transfected or not with miR-124 mimics or scramble for 24 h (magnification, ×200). Results from Transwell invasion assays are presented. (D) The relative invasion of OCVAR3 cells were transfected or not with miR-124 mimics or scramble for 24 h. (E) The SKOV3 cells were transfected or not with miR-124 mimics or scramble for 24 h (magnification, ×200). Results from Transwell invasion assays are presented. (F) The relative invasion of SKOV3 cells were transfected or not with miR-124 mimics or scramble for 24 h. The data from three in vitro independent experiments are presented (**P<0.01). NC, negative control; miR, microRNA.
