Figure 2 Possible roles of glypican-3 in progression of hepatocellular carcinoma. Cell surface glypican-3 (GPC3) forms a complex with Wnt and heparin-binding growth factors such as fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) via its heparan sulfate (HS) side chains and stimulates receptor-mediated signaling in hepatocellular carcinoma (HCC) cells. SULF2 expressed in HCC cells cleaves the HS to release these ligands from the GPC3/ligand complex, which may also upregulate signaling in neighboring HCC cells.
