The Western blot results showed that overexpression of miR-21-5p and MELK increased the levels of vimentin, fibronectin, N-cadherin, and decreased the level of E-cadherin (Figure 2(g)), illustrating that overexpression of miR-21-5p and MELK promoted EMT in HCC cells. This evidence concerns the gene FN1 and hepatocellular carcinoma.
