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.

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 ]. Bhargava AK, O'Donnell AM, Birl T, et al. Plasma lipid-bound sialic acid (LSA) in cancer and noncancer patients.

Although the cancer specificity of sialic acid is reported to be high, its sensitivity is low because sialic acid-rich glycoproteins are present in inflammatory diseases (Narayanan, 1994). 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. The diagnostic usefulness of 95.6% was similar to that reported with Sialic acid is a constituent of many salivary glycoproteins. Studies have reported elevated salivary levels of sialic acid in pregnancy, Down's syndrome, and diabetes mellitus., Dablesteen et al., have reported elevated salivary sialic acid in oral cancer.

13 Sep 2016 Here, we designed biotherapeutic molecules, termed “antibody–enzyme conjugates,” that selectively remove sialic acids from tumor 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). This is summarized in Figure 1.

2021-02-24 · One of the glycan moieties generally overexpressed in cancer are sialic acids, which can induce immunomodulatory properties via binding to Siglec receptors. We here show that Pancreatic Ductal 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.
