Heterogeneity in phenotypes of malignantly transformed cells and aberrant glycan expression on their surface are two prominent hallmarks of cancers that have hitherto not been linked to each other. In this paper, we identify differential levels of a specific glycan linkage: α2,6-linked sialic acids within breast cancer cells in vivo and in culture. Upon sorting out two populations with

1984; 30:940, 36th National Meeting of the American Association for Clinical Chemistry July 29−August 3, 1984, Washington, DC. Altered cell surface sialylation is a hallmark of cancer. Investigation of clinical samples, cell lines and animal models has revealed associations between aberrant sialylation and cancer progression. Total serum and lipid bound sialic acid (Sia) levels are elevated in many types of cancer displaying a positive correlation with cancer stage and grade. The expression of α2-3 and α2-6 linked Elevated cell surface sialic acid expression levels on colorectal cancer cells has been associated with increased metastatic burden. Sialic acid expression influences cancer cell-cell adhesion, cell-extracellular matrix adhesion, as well as emboli formation, apoptosis and cell growth. Serum lipid-bound sialic acid (LSA) was measured with a recently described procedure in 108 healthy subjects and in 138 patients with a variety of solid tumors and hematologic malignancies. At the time of serum sampling, 128 patients had active disease and 10 patients had no evidence of disease.

Researchers at the University of California, San Diego School of Medicine say antibodies to a non-human sugar molecule commonly found in people may be useful as a future biomarker for predicting cancer risk, for diagnosing cancer cases early and, in sufficient concentration, used as a treatment for suppressing tumor To hit cancer cells but not normal ones, her team linked the sialic acid–trimming enzyme to an antibody specific for a common tumor antigen—in this case, the antigen HER2, which is found on Altered cell surface sialylation is a hallmark of cancer.

Sialic acid sugars on the surface of cancer cells have emerged as potent immune modulators that contribute to the immunosuppressive microenvironment and tumor immune evasion. However, the mechanisms by which these sugars modulate antitumor immunity as well as therapeutic strategies directed against them are limited. Knocking out a key gene in sialic acid metabolism, Cmas, inhibits synthesis of the activated form of sialic acid, cytidine monophosphate-sialic acid and decreases the formation of lung metastases in vivo. Thus, the sialic acid pathway may be a new target against metastatic breast cancer. Sialic acid-rich glycoproteins (sialoglycoproteins) bind selectin in humans and other organisms.

Accordingly, selective strategies to interfere with sialic acid synthesis Sialic acids are nine-carbon acidic monosaccharides found in terminal position of glycan chains. The sialylation of cell surface glycoconjugates is frequently altered in cancers, resulting in the Focus on sialic acid as a tumor marker should be examined from the perspective of aberrant glycosylation in cancer cell membranes owing to activation of new glycosyl transferases that are characteristic of tumor cells, and the role played by sialic acid in tumor cell metastasis including increased capacity to adhere to vascular endothelium, and decreased capacity of cancer cells to be Sialic acids are nine-carbon acidic monosaccharides found in terminal position of glycan chains.

Abstract Sialic acids are nine-carbon acidic monosaccharides found in terminal position of glycan chains. The sialylation of cell surface glycoconjugates is frequently altered in cancers, resulting in the expression of sialylated tumor-associated carbohydrate antigens that are specific markers for this disease.

In oral potentially malignant disorders (OPMDs) and oral cancer (OC), the sialic acid level is seen to increase due to high cell turnover and shedding of malignant cells which, in turn, results in the release of glycoproteins like sialic acid into circulation. Sialic Acids and Hypersialylation in Cancer Sialic acids are a family of nine-carbon monosaccharides commonly observed terminating glycan chains of glycoproteins and glycolipids on the outer membrane of mammalian cells. Breast cancer cells use the various roles of sialic acid (Sia) for their progression and metastasis [ 4, 5 ].

This is summarized in Figure 1. Total serum and lipid bound sialic acid (Sia) levels are elevated in many types of cancer displaying a positive correlation with cancer stage and grade. The expression of α2-3 and α2-6 linked Sia and the levels of sialylated structures sialyl-Tn, sialyl Lewis a (SLea) and sialyl Lewis x (SLex) are also elevated in cancer cases. Abstract Sialic acids are nine-carbon acidic monosaccharides found in terminal position of glycan chains. The sialylation of cell surface glycoconjugates is frequently altered in cancers, resulting in the expression of sialylated tumor-associated carbohydrate antigens that are specific markers for this disease. Precise profiling of the sialic acid (SA) expression on the membrane of cancer cells is critical for early identification of cancers and assessment of cancer metastasis.
