Expression of a Core 3 Disialyl-Le(x) Hexasaccharide in Human Colorectal Cancers: A Potential Marker of Malignant Transformation in Colon.
Cancer-associated alterations in cell surface and secreted glycoproteins have been catalogued for many years but many of the studies of alterations in mucin carbohydrate have relied on histochemical or immunohistochemical methods, with little direct chemical analysis. In this study, we analyzed the O-glycosylation pattern of MUC2 glycoprotein isolated from colorectal carcinomas, transitional mucos
