STARD13 and breast cancer: The previous studies have shown Tanshinone IIA effects on regulating miRNAs activity [8, 44, 45] and Tanshinone IIA could inhibit the migratory and invasive ability of cervix carcinoma stem cells via inhibition of YAP transcriptional activity that is also suppressed by STARD13 3'UTR [11]; these effects promote us to assess whether Tanshinone IIA could attenuate miR-125b activity in breast cancer cells.
