Virus receptorer: betydelse för tropism och behandling
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.

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).

Sialic acids are a family of negatively charged, nine-carbon sugar molecules that often terminate the glycans of cell surface glycoproteins and glycolipids. Human cancer cells cover their membrane with a dense layer of sialoglycans and also express unique sialoglycans on their surface (e.g., SLe a / x, STn, GM2/3, GD2/3, or SSEA-4; refs. 4–6).
