We next survey the correlation between the levels of the three common miRNAs and the STARD13 ceRNAs in breast cancer cells and tissues with distinct metastatic capabilities as well as the effect of STARD13- and its ceRNAs-3’UTRs on breast cancer metastasis via gain- and loss-of-function study in vitro and in vivo. Here, STARD13 is linked to breast carcinoma.
