Our findings are consistent with previous studies reporting the ability of miR-934 and miR-30a to promote metastasis as well: miR-934, along with host gene VGLL1, was found to be upregulated in ER-negative BRCA1-positive breast cancers and was associated with the acquisition and maintenance of luminal progenitor characteristics [29]; similarly, miR-30a was shown to promote invasion in nasopharyngeal carcinoma (NPC) via the repression of E-cadherin and induction of epithelial-to-mesenchymal transition (EMT) [30]. Here, BRCA1 is linked to breast carcinoma.
