In a recent analysis of a series of resected HCC specimens, a mesenchymal phenotype (high vimentin and low E-cadherin expression) was associated with shorter survival and enhanced TGF-β pathway activity (increased TGF-β1, phospho-SMAD-2, and phospho-β1 integrin expression)[58]. The gene discussed is TGFB1; the disease is hepatocellular carcinoma.
