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. The sialylation of cell surface glycoconjugates is frequently altered in cancers, resulting in the Sialic Acid and Cancer | SpringerLink Mechanistic studies have shown that hypersialylation on cancer cells can engage inhibitory Siglecs on the surface of immune cells and induce immunosuppression. These recent studies strongly suggest that the Siglec–sialic acid axis can act as a potential target for cancer immunotherapy. Glycoproteins like sialic acid are expressed on the cell surface. 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 ].

Sialic acid cancer

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.

One key change of malignant tissue glycosylation is the alteration o … Sialic Acids and Apoptosis Evasion in Cancer Resisting cell death is one hallmark of cancer cells (18). 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.

sialic acids (Sia) are often terminating units of N- and O-linked glycoproteins and glycosphingolipids that can be found on the cell surface as part of the glycocalyx, as well as on secreted Development of Sialic Acid-coated Nanoparticles for Targeting Cancer and Efficient Evasion of the Immune System Young-Hwa Kim 1* , Kyung Hyun Min 1* , Zhantong Wang 1 , Jihoon Kim 1 , Orit Jacobson 1 , Peng Huang 2 , Guizhi Zhu 1 , Yijing Liu 1 , Bryant Yung 1 , Gang Niu 1 , Xiaoyuan Chen 1 sialic acid precursors: N-propanoylmannosamine (ManNProp), N-butanoylmannosamine (ManNBut), N-pentanoylmannosamine (ManNPent) and N-hexanoylmannosamine (ManNHex) and we treated MCF7 breast cancer cells with those 5-acyl modiﬁed mannosamines. Serum sialic acid was significantly greater in cancer patients than in normals. Cancer patients with metastases had significantly greater sialic acid than cancer patients without metastases.

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. 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.
