miR-215 was downregulated in breast cancer tissues and cell lines. (A) Expression levels of miR-215 were significantly decreased in the breast cancer tissues compared with matched adjacent non-tumor breast tissues. Data are presented as the mean ± standard deviation. *P<0.05 vs. adjacent non-tumor breast tissues. (B) Relative expression of miR-215 was lower in all breast cancer cell lines examined compared with MCF-10A. *P<0.05 compared with MCF-10A. miR-215, microRNA-215.
