miR-9 overexpression signifycantly upregulated E-cadherin and downregulated vimentin, and the miR-9 inhibitor had the opposite effect (Figure 7A). As expected, EIF5A2 knockdown had the same effect on E-cadherin and vimentin expression as miR-9 overexpression (Figure 7B). When HCC cells were co-transfected with EIF5A2 siRNA and miR-9 inhibitor, the expression of E-cadherin and Vimentin showed no difference (Figure 7C). This evidence concerns the gene CDH1 and hepatocellular carcinoma.
