Several mucin-related molecules involved in carbohydrate metabolism and protein glycosylation were identified including FUT3, GCNT3, SI, FBP1, UGT1A9; and TFF1, an estrogen-regulated member of the trefoil factor family of secreted peptides associated with mucin production and frequently overexpressed in other mucinous adenocarcinomas (Emami et al, 2004). Here, GCNT3 is linked to mucinous adenocarcinoma.
