Mucin associated Tn and sialosyl-Tn antigen expression in colorectal polyps.
Sialosyl-Tn antigen and its immediate precursor, Tn antigen, are carbohydrate structures associated with the earliest steps of mucin O-linked glycosylation. Both antigens have been shown previously to be highly sensitive and specific markers of colorectal cancer. One hundred and three colorectal polyps (79 adenomatous; 24 hyperplastic) were examined for expression of Tn antigen using vicia vill...
متن کاملAutoradiographic studies of tn/tn mouse embryos.
High-resolution autoradiographic studies were used to determine whether t12/t12 and tw32/tw32 mouse embryos synthesize the excessive lipid which distinguishes these embryos prior to their death. The studies show that the tn homozygotes synthesize neutral lipid which is stored in intracellular lipid droplets. Cholesterol and phospholipid precursors are not incorporated into these droplets.
متن کاملExpression of Tn and sialyl Tn antigens in synovial tissues in rheumatoid arthritis.
OBJECTIVES The carbohydrate chains represented by mucins (MUCs) are expressed by a variety of normal and malignant secretory epithelial cells and induce a variety of immunoreactions. Tn and sialyl Tn antigens are tumour-associated carbohydrate antigens which are borne on the core proteins of mucins. The purpose of this study is to investigate the existence of tumour-associated carbohydrate anti...
متن کاملExpression of Tn, sialosyl-Tn, and T antigens in human colon cancer.
Mucin glycoproteins are major secretory products of the colon and contain O-linked oligosaccharides synthesized on a polypeptide backbone. The initial step in the synthesis of O-linked oligosaccharides is the addition of N-acetylgalactosamine to serine or threonine residues forming the Tn antigen. This substance can then receive additional carbohydrate residues such as sialic acid to form sialo...
متن کاملChallenges in Antibody Development against Tn and Sialyl-Tn Antigens
The carbohydrate antigens Tn and sialyl-Tn (STn) are expressed in most carcinomas and usually absent in healthy tissues. These antigens have been correlated with cancer progression and poor prognosis, and associated with immunosuppressive microenvironment. Presently they are used in clinical trials as therapeutic vaccination, but with limited success due to their low immunogenicity. Alternative...
