The expression of miR-26a was reduced in breast cancer cell lines and clinical specimens.

<p>A. Expression of miR-26a in the 2 immortalized normal mammary epithelium cell lines and 4 breast cancer cell lines. B. Average expression level of miR-26a in human breast cancer tissues and normal breast tissues. MiRNA abundance was normalized to 5s rRNA. *P<0.05 compared with control.
