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 Acids and Cancer Progression and Metastasis. Elevated expression of sialoglycans correlates with tumor aggressiveness and their capacity to metastasize and invade surrounding tissue, and therefore correlates with a poor prognosis for patients with cancer ( 27 ).

Learn how and why to include it in your water Tumors in minor salivary glands are uncommon, but when they do occur they are more likely to be cancerous. Minor salivary gland tumors most often start in the 20 Feb 2017 The roles of glycans in cancer have been highlighted by the fact that alterations in glycosylation could promote invasive behaviour of tumor cells 1 Sep 2009 Serum Sialic Acid in Normals and in Cancer Patients · Supplementary Materials Product Information Journal and Issue. 13 Sep 2016 Here, we designed biotherapeutic molecules, termed “antibody–enzyme conjugates,” that selectively remove sialic acids from tumor cells.

Sialic acids sweeten a tumor's life. Over four decades ago, specific tumor characteristics were ascribed to the increased expression of sialic acid sugars on the surface of cancer cells, and this led to the definition of sialic acids as potential therapeutic targets. Recent advances in glycobiology and cancer research have defined the ….

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] ].

Sialic acid level in body fluids is also an important marker for diagnosing cancer. Simple, direct and automation-ready procedures for measuring

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).

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.

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.

Sialic acids in cancer biology and immunity During malignant transformation, glycosylation is heavily altered compared with healthy tissue due to differential expression of glycosyltransferases, glycosidases and monosaccharide transporters within the cancer microenvironment. One key change of malignant tissue glycosylation is the alteration o …

However, the mechanisms by which these sugars modulate antitumor immunity as well as therapeutic strategies directed against them are limited. 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] ].

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 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. Overview of sialic acid changes and their role in tumorigenesis and cancer progression. Intracellular changes in sialyltransferase expression alters glycan processing within the Golgi. Changes in sialidase expression effects the sialic acid status of glycans during processing, transport in lysosomes, and at the cell membrane. Significantly elevated serum sialic acid concentrations were found in breast cancer, and showed correlation with tumour stage.
