Fig. 5: MiR-370-3p promotes breast cancer cell migration and invasion in vitro.

a, b Wound healing assay of the migration abilities of MDA-MB-231 cells transfected with miR-370-3p mimic, miR-370-3p inhibitor, or their respective controls. Scale bar: 200 μm. c, d Transwell assay of the migratory and invasive abilities of MDA-MB-231 cells transfected with miR-370-3p mimic, miR-370-3p inhibitor, or their respective controls. Scale bar: 100 μm. e qRT-PCR analysis of miR-370-3p expression in breast cancer tissues and the corresponding adjacent non-cancerous tissues (n = 45). f Spearman correlation analysis of the association between FGF14-AS2 and miR-370-3p expression in 45 breast cancer tissues. Data are the mean ± SD of three independent experiments. *P < 0.05; **P < 0.01; ***P < 0.001.
