miR-539 was significantly down-regulated in breast cancer tissues and cell lines. (A) Relative expression levels of miR-539 in 38 pairs of breast cancer tissues and matched normal breast tissues were analysed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). (B) Relative expression of miR-539 in two breast cancer cell lines (MDA-MB-231 and MCF7) and a human normal mammary epithelial cell line (MCF-10A). miRNA: microRNA. *P < 0.05.
