Effects of miR-144 on ovarian cancer cells proliferation, migration, and invasion. (A, B) MTT assay was performed to determine the proliferation in SKOV3 and OVCAR3 cells transfected with miR-NC or miR-144 mimics. (C, D) Wound healing assay and Transwell invasion assay were performed to determined cell invasion in OC cells transfected with miR-NC or miR-144 mimics. The quantitative analysis of Transwell assays and wound healing assay is shown in the pictures. (E, F) MMP2 and MMP9 expression were measured by qRT-PCR and Western blot.
