Expression of miR-615 in human breast cancer cell lines and tissues. (A) Real-time PCR analysis of miR-615 expression in normal breast cells (NBEC) and breast cancer cell lines, including BT549, MCF-7, Bcap37, MDA-MB231, ZR-75-30, SKBR3, MDA-MB435, MDA-MB453 and T47D. (B) Relative miR-615 mRNA expression levels in 8 paired primary breast cancer tissues (T) and the matched adjacent non-tumor tissues (ANT) from the same patient were detected by PCR analysis. Experiments were repeated at least three times (A and B). Each bar represents the mean of three independent experiments. *P < 0.05.
