TGFB1 and hepatocellular carcinoma: We found that protein levels of the mesenchymal markers, Vimentin and N-Cadherin, were up-regulated in Hep3B cells (epithelial-like) upon C3G down-regulation (Figure 3C), reaching levels comparable to those found in non-silenced cells upon a short-term treatment with TGF-β1, a well-known inducer of EMT in HCC cells [39,40,41].
