FUT8 and carcinoma: It is important to note that β1,6-branched, bisected (β1,4 GlcNAc) and core fucosylated (α1,6 fucose) N-glycans are enzymatic products of N-acetylglucosaminyltransferase V (MGAT5), N-acetylglucosaminyltransferase III (MGAT3) and α1,6-Fucosyltransferase (FUT8), respectively; in epithelia, changes in the expression patterns of these N-glycans have been associated with several pathologies, including carcinomas [21].
