Sialic acids sweeten a tumor's life. Over four decades ago, specific tumor characteristics were ascribed to the increased expression of sialic acid sugars on the surface of cancer cells, and this led to the definition of sialic acids as potential therapeutic targets. Recent advances in glycobiology and cancer research have defined the ….

Cancer cells exhibit higher concentrations of Sialic acid thn healthy cells Corrections [ edit ] The carboxyl group of the beta-anomer should be labelled 1 rather than the 2-hydroxyl group.

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. Metastatic cancer cells often express a high density of sialic acid-rich glycoproteins. This overexpression of sialic acid on surfaces creates a negative charge on cell membranes. Regardless of the change in the underlying glycan structure, the upregulation and alteration of terminal sialic acid structures (Sia) is a hallmark of cancer (Amon et al.

At the time of serum sampling, 128 patients had active disease and 10 patients had no evidence of disease. LSA was elevated in 104 of 128 (81.2%) patients with active disease, while carcinoembryonic antigen N-acetyl neuraminic acid, the most prominent member of the acidic sugar family known as sialic acids, is ubiquitous on the surface of eukaryotic cells where, as a glycoconjugate substituent, it is involved in numerous important biological processes. Polysialic acid (PSA), an α-(2-8)-linked homopolymer of N-acetyl neuraminic acid, is equally as important biologically; however, its expression Cancer cells exhibit higher concentrations of Sialic acid thn healthy cells Corrections [ edit ] The carboxyl group of the beta-anomer should be labelled 1 rather than the 2-hydroxyl group. Sialic acid level in body fluids is also an important marker for diagnosing cancer.

Mutations or downregulation of molecules involved in the Fas receptor–Fas ligand (FasR–FasL) apoptotic pathway are well-known mechanisms exploited by cancer cells to escape apoptosis. Abstract Changes in glycosylation during tumour progression are a key hallmark of cancer. One of the glycan moieties generally overexpressed in cancer are sialic acids, which can induce Regardless of the change in the underlying glycan structure, the upregulation and alteration of terminal sialic acid structures (Sia) is a hallmark of cancer (Amon et al. 2014).

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. Se hela listan på frontiersin.org 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.
