WebMar 13, 2008 · The Tn antigen (GalNAcα-Ser/Thr) is a biosynthetic intermediate in the formation of normal mucin-type O-glycans and is typically extended by the action of the enzyme core 1 β3 galactosyltransferase (core 1 β3Gal-T, T-synthase; ref. 11).Thus, Tn antigen expression results from lack of T-synthase activity. WebFeb 24, 2016 · Activation of an aberrant glycosylation pathway in cancer cells can lead to expression of the onco-foetal sialyl-Tn (sTn) antigen. STn is a truncated O-glycan containing a sialic acid α-2,6 linked to GalNAc α-O-Ser/Thr and is associated with an adverse outcome and poor prognosis in cancer patients. The biosynthesis of the sTn antigen has been …

While the T and ST antigens are found on normal O-glycans such as in hematopoietic cells , ST3Gal1 overexpression is found in different types of malignancies (61–65), and has been linked to poor prognosis (65, 66).
Websialylated T-antigen glycan exists at the PSGL-1 N terminus. Furthermore, a competition between the (2,6)sialyl-transferase ST6GalNAc2 and core-2 N-acetylglucosaminyl-transferase C2GnT-1 regulates the relative expression of the di-sialylated T-antigen and the sLeX epitope at Thr-57. This WebThe present invention relates to a method for diagnosing whether a subject may be at risk for or may suffer from cancer wherein (significantly) lower or (significantly) higher binding of a binding agent to a particular glycan structure of a biomarker glycoprotein compared to a control sample is indicative for said subject to be at risk for or to suffer from cancer.
WebAug 31, 2024 · The cell surface of cancer cells is covered in a dense layer of sialylated glycans, which can include sialyl-Tn (sTn), sialyl-T (sT) and sialyl-Lewis antigens, polysialic acid, and gangliosides (Figure 1 and Table 1). These tumour-associated antigens are often exploited as markers for the detection and monitoring of cancer [15,40].
