CDH1 and hepatocellular carcinoma: Ectopic FGF15/19 expression promotes epithelial-mesenchymal transition and invasion in epithelial-like HCC cells through the repression of E-cadherin expression, whereas FGF15/19 knockdown enhances E-cadherin expression and, hence, diminishes epithelial-mesenchymal transition traits in mesenchymal-like HCC cells.
