It was noteworthy that α1,3fucoslyated glycans of AGP were synthesized in the liver by an action of the FUT6 gene encoded α1,3fucosyltrasnferase, and that tumor-associated elevations of both fAGP levels and α1,3fucosyltrasnferase activities were widely determined in plasma samples from various cancer patients with no organ specificity [23,24,25,26,30]. Here, FUT6 is linked to cancer.
