Sialyl-tn expression

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. WebThe truncation of O-linked glycans has been widely described in various gastrointestinal carcinomas and results in the de novo expression of short O-glycans such as the Thomsen-Friedenreich (TF or T, Galβ1-3GalNAcα1) antigen, Thomsen-nouvelle (Tn, GalNAcα1) and its sialylated form sialyl Tn (STn, Neu5Acα2–3GalNAcα1) .
