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 ].

Sialic acid storage disease is an inherited disorder that primarily affects the nervous system. Explore symptoms, inheritance, genetics of this condition. Sialic acid storage disease is an inherited disorder that primarily affects the nervo

Bhargava AK, O'Donnell AM, Birl T, et al. Plasma lipid-bound sialic acid (LSA) in cancer and noncancer patients. Clin Chem. 1984; 30:940, 36th National Meeting of the American Association for Clinical Chemistry July 29−August 3, 1984, Washington, DC. Carolyn Bertozzi showed that cancer cells use sialic acid–capped glycans to evade immune detection. Her company Palleon Pharmaceuticals is developing glycoimmune drugs that work to remove that cloak in a mechanism analogous to that used by the approved checkpoint inhibitor therapies.

Sialic acid cancer

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. 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.

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. Molecularly imprinted nanoparticles were prepared as surface-enhanced Raman scattering tags for the selective imaging of cancer cells and tissues against normal cells and tissues relying on the use of sialic acid-templated imprinting to recognize cancer cells, which are over-expressed with sialic acid at the Investigating the specificity of molecularly imprinted polymers targeting sialic acid on cancer cell surfaces: Author: Beyer, Sarah: Date: 2020: Publisher: Malmö universitet/Hälsa och samhälle: Language: eng (iso) Subject: Cancer cell surfaces Glycans Glycosaminoglycans Molecularly imprinted polymers Nanoparticles Sialic acid: Handle Disruption of sialic acid metabolism drives tumor growth by augmenting CD8 + T cell apoptosis Lenneke A.M. Cornelissen Amsterdam UMC, Vrije Universiteit Amsterdam, Department of Molecular Cell Biology and Immunology, Cancer Center Amsterdam, Amsterdam Infection and Immunity Institute, Amsterdam, The Netherlands Heterogeneity in phenotypes of malignantly transformed cells and aberrant glycan expression on their surface are two prominent hallmarks of cancers that have hitherto not been linked to each other. In this paper, we identify differential levels of a specific glycan linkage: α2,6-linked sialic acids within breast cancer cells in vivo and in culture.
