miR-96 regulates migration and invasion of bladder cancer through epithelial-mesenchymal transition in response to transforming growth factor-β1.

Bladder cancer (BC) is one of the most frequent urological malignancies, and its molecular mechanism still remains unclear. Recent studies have revealed that MicroRNA (miRNAs) acted as oncogenes or tumor suppressors in a variety of cancers. MiRNA-96 has been reported to play a significant role in the development and progression of many cancers. In the current study, we found that transforming growth factor (TGF)-β1 played a significant role in the progression that miR-96 conducted. And TGF-β1 could also regulate the expression of FOXQ1, which is the target gene of miR-96. Furthermore, miR-96 induced epithelial-mesenchymal transition in BC cells, which is driven by TGF-β1. In conclusion, our data revealed that miR-96 regulates the progression and epithelial-mesenchymal transition, which is driven by TGF-β1 in BC cells; it may provide a new thought for the therapy of BC.
