miRNAs were highly expressed in triple positive breast cancer tissues. (A-D) Total RNA was extracted from 14 triple negative and 36 triple positive breast cancer tissues to detect miRNAs expression by QPCR. MicroRNAs expression was normalized with respect to RNU6B as an internal control. T-test was used to indicate the difference. P values are shown in the figures. TP denotes triple positive breast samples, TN means triple negative breast samples.
