The glycosaminoglycans of the human colon in inflammatory and neoplastic conditions.
The glycosaminoglycans from normal colonic mucosa and colons with a variety of inflammatory diseases, as well as benign and malignant neoplasms were analyzed. Normal colonic mucosa contains predominantly chondroitin sulfates and dermatan sulfate. Increases in the levels of hyaluronic acid and heparan sulfate, as well as substantial increases in the amount of total glycosaminoglycans were characteristic of invasive colonic adenocarcinoma. Lesser elevations in the amount of total glycosaminoglycans and hyaluronic acid and heparan sulfate were present in neonatal colonic mucosa, villous adenoma, ulcerative colitis, and mucosa adjacent to carcinoma. The degree of elevation was proportional to the dysplastic potential. Since dysplastic lesions have scant connective tissue, the epithelial component of colonic neoplasms may contribute to these neoplasm-related alterations in glycosaminoglycan composition.[1]References
