FUT1 and cancer: Several reports have demonstrated that overexpression of FUT1 is associated with enhanced tumor cell proliferation and tumorigenicity, whereas silencing of FUT1 exerts the opposite effects.5, 6, 7, 8 In addition, the involvement of FUT1 in other cellular processes such as adhesion,4, 9 migration,10 apoptosis1 and angiogenesis have also been demonstrated.11, 12 Although the importance of α1,2-fucosytransferase in cancer biology processes has been reported, the molecular mechanisms involved remains largely unclear.
