Expression of ACTA2-AS1 and miR-532-5p in TNBC tissues. A, B Significant downregulation of ACTA2-AS1 (A) and upregulation of miR-532-5p (B) were observed in TNBC tumor tissues. ***P < 0.001 compared with normal paracancerous tissues. C The expression of miR-532-5p was negatively correlated with the expression of ACTA2-AS1. r = − 0.701, P < 0.001
