CDH1 and hepatocellular carcinoma: found that the downregulation of FOFX2 expression in HCC cells resulted in the increase of E-cadherin and the decrease of vimentin, induced mesenchymal epithelial transformation (MET) of HCC, inhibited the invasion and migration of HCC cells, promoted the proliferation of HCC cells, enhanced the colonization of circulating HCC cells, and consequently promoted the formation of metastatic nodules.
