MiR-223 represses proliferation and invasion of BC cells. (a) Verification of miR-223 expression in T24, SW780 and SV-HUC-1 cells using qRT-PCR assay. (b) Proliferation assay in T24, SW780 and SV-HUC-1 cells transfected with miR-223 mimic or miR-223 inhibitor as indicated. (c, d, e) Cell invasion assay in T24 (c), SW780 (d) and SV-HUC-1(e) cells transfected as indicated. (f) Verification of miR-223 overexpression in SW780 cells using qRT-PCR assay. (g, h) Proliferation (g) and invasion (h) assay in SW780 cells transfected with miR-223 mimic or control mimic. *P < 0.05.
