FUT5 was overexpressed in intrahepatic cholangiocarcinoma tissues compared with corresponding adjacent nontumor tissues, which promotes the proliferation and migration of intrahepatic cholangiocarcinoma cells by mediating the fucosylation of versican and β3 integrin, which are involved in the interaction of cells with the extracellular matrix to exert precancer effects.133. The gene discussed is VCAN; the disease is intrahepatic cholangiocarcinoma.
