Figure 4. Overexpression of miR-136-5p reduces TNBC cell proliferation, migration, and invasion. (A) Relative miR-136-5p expression in TNBC cells transfected with mimic control or miR-136-5p mimic. (B, C) Proliferation of TNBC cells transfected with mimic control or miR-136-5p mimic, analyzed by CCK8 assay. (D, E) Wound healing assay of the migration capacity of TNBC cells transfected with mimic control or miR-136-5p mimic. (F, G) Migration and invasion of TNBC cells transfected with mimic control or miR-136-5p mimic, analyzed by transwell assays. Scale bars, 100 μm. * p < 0.05 compared to controls.
