WebThe three carcinomas also differed from each other on the expression of tumor-associated antigens. In noncancerous mucosal epithelium at the anastomosis showing hyperplasia and cystic formation of glandular epithelial cells, no genetic alterations were detected, but sialyl-Tn and carbohydrate antigen 19-9 were expressed. WebSialyl-Tn is a carbohydrate antigen overexpressed in several epithelial cancers including breast cancer, and usually associated with poor prognosis. Sialyl-Tn is synthesized by a CMP-Neu5Ac: GalNAc alpha2,6-sialyltransferase: ST6GalNAc I, which catalyzes the transfer of a sialic acid residue in alpha2,6-linkage to the GalNAcalpha1-O-Ser/Thr structure.
