About glycans in cancer and chronic Inflammation

Cancers consistently modify glycans (polysaccharides) on the surface of tumor cells. These cancer-associated glycans are attractive targets for antibody therapeutics. In addition, a specific glycan in the diet - N-glycolylneuraminic acid ("Neu5Gc") – is a common sialic acid associated with inflammation, cancer and cardiovascular disease. Most humans ingest Neu5Gc through dietary intake of red meat and dairy products.  After ingestion, Neu5Gc can be incorporated into the surface of human cells and subsequently treated as a foreign antigen by the immune system, resulting in a chronic inflammatory response. This chronic inflammatory state may help explain the association between dietary red meat and the progression of cancer and cardiovascular disease, as well as other chronic inflammatory disorders. Neu5Gc is overexpressed in solid tumors and can modify cancer-associated glycans, thereby increasing their cancer specificity.

About Sialix, Inc.

Sialix, Inc is developing products for the treatment and prevention of cancer and chronic inflammatory conditions associated with ingestion of non-human sialic acids which are found in red meat and other dietary sources. The company is advancing two complementary programs: an oncology therapeutic targeting ovarian and other solid tumors, and a prophylactic nutritional supplement to reduce inflammation and the resulting risk of cancer and cardiovascular disease. Sialix has licensed a broad patent portfolio from UCSD and assembled a team of industry veterans and glycobiology experts to support the development of these products. The company is headquartered in Cambridge, Massachusetts. Learn more at www.sialix.com
