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. In two cancer patients, sialic acid levels returned to normal after surgery.

This process was largely unknown until fairly recently; cancer cells may be using sialic acid to allow themselves to pass immune cell inspection. Sialic acid is a class of sugars found on the surface of a cell. sialic acid. 131-48-6.

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 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.

Significantly elevated serum sialic acid concentrations were found in breast cancer, and showed correlation with tumour stage. Serum sialic acid values did not correlate with CEA values. The results suggest that measurement of serum sialic acid concentrations may be of adjunctive value in assessing tumour stage. 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. 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.

2014). 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.

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 One type of glycosylation often altered in cancer is associated with the monosaccharide sialic acid (Sia) and changes in sialylation are commonly observed [ [ 4 - 7] ]. Sias are nine‐carbon atom monosaccharides that are present at the terminal end of the glycan chain [ [ 8, 9] ]. Sialic acid (SA) has been found to be a key constituent in the glycans of cell membrane proteins or lipids, and it has proven to correlate with several pathological processes, in particular, the cancers [ 31, 32 ].

Thus, for example, U.S. Pat. No. 4,146,603 to Davidson et al discloses and claims a fairly complex series of procedures whereby elevated sialic acid content is a determinant with respect to cancer specific determinations.
