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.
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
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. Metastatic cancer cells often express a high density of sialic acid-rich glycoproteins. This overexpression of sialic acid on surfaces creates a negative charge on cell membranes.

Role of microglial-derived tumor necrosis factor in mediating CD14 av C Andermyr · 2012 — and colonization can lead to chronic gastritis and stomach cancer. where anti-adhesion of bacterial lectins to sialic acid-glycosylated Maligna tumörer är det man kallar cancer, dessa kan då sprida sig och att cellen producerar ett tjockare lager med glycocalyx molekyer, som sialic-acid. Involvement of a non-human sialic acid in human cancerSialic acids are common monosaccharides that are widely expressed as outer terminal units on all en cancerframkallare eftersom infektionen kan leda till cancer i magen.
13 Sep 2016 Here, we designed biotherapeutic molecules, termed “antibody–enzyme conjugates,” that selectively remove sialic acids from tumor cells.
Dealing with heartburn and stomach acid troubles is an uncomfortable condition that nearly everyone experiences from time. For some people, it's a sign of gastroesophageal reflux disease (GERD). If you're struggling to get stomach acid reli From trouble sleeping to frequent heartburn, the symptoms of acid reflux can cause discomfort, impacting your day-to-day life and your health, too.
iv) that sialic acid containing glycans have been developed as a novel type of Vi och många andra tror att man i framtiden ska kunna behandla cancer,
It interacts with SIALIC ACIDS and mediates signaling from B-CELL ANTIGEN RECEPTORS. Biochemical studies on Sialic acid derivatives in patients with oral cancer.
Researchers at the University of California, San Diego School of Medicine say antibodies to a non-human sugar molecule commonly found in people may be useful as a future biomarker for predicting cancer risk, for diagnosing cancer cases early and, in sufficient concentration, used as a treatment for suppressing tumor
Much work has been done which indicates that elevated sialic acid content in blood sera of a patient is an indication of the presence of cancer. 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. For many viruses, the first step to invading a cell is finding and attaching to just the right variety of sialic acid, a type of sugar molecule that is found on the surface of most animal cells, including those of humans. To understand the roles that sialic acids play in viral infections, Dr. Colin Parrish’s group at the Baker Institute for Animal Health are using new techniques to explore
Cancer cells seemingly have the ability to disguise themselves as healthy. This process was largely unknown until fairly recently; cancer cells may be using sialic acid to allow themselves to pass immune cell inspection.

1984; 30:940, 36th National Meeting of the American Association for Clinical Chemistry July 29−August 3, 1984, Washington, DC. Altered cell surface sialylation is a hallmark of cancer. Investigation of clinical samples, cell lines and animal models has revealed associations between aberrant sialylation and cancer progression.
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 …
Sialic acid describes derivatives of neuraminic acid, which are potentially useful tumor markers because of the aberrant glycosylation in cancer cell membranes. 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).
