VIM and neoplasm: In addition to the modulatory effects on tumor cell behaviors in vitro, the present study data also demonstrated that miR-30a-5p genetic delivery in UTUC BFTC-909 cells could restore the expression of the epithelial marker E-cadherin, and concomitantly suppress the expression of mesenchymal markers, including vimentin, fibronectin, and α-SMA proteins.
