CTHRC1 and miR-30c expression are inversely correlated in human breast cancer cells and tissues. a The relative expression level of miR-134, miR-155, miR-30c and miR-630 in breast cancer cells respectively was detected by qRT-PCR. *P < 0.05, **P < 0.01. b The relative expression level of miR-30c in normal breast tissue, 5 benign breast tumor tissues and 18 paired breast cancer tissues was detected by qRT-PCR. c Correlation analysis of miR-30c expression and CTHRC1 expression in clinical breast cancer samples. r = −0.56, P = 0.0143
