beta-D-Xylosides are often used to competitively inhibit proteoglycan synthesis by serving as primers for free glycosaminoglycan (GAG) chain assembly. Quite unexpectedly, we found that when human melanoma cells and Chinese hamster ovary cells are labeled with [3H] galactose in the

Human skin fibroblasts were incubated in the presence of a fluorogenic xyloside, 4-methyl-umbelliferyl-beta-D-xyloside (Xyl-MU), then the cultured medium was recovered, concentrated with a lyophilizer, and dialyzed against distilled water. The structures of the Xyl-MU derivatives purified from the dialyzable fraction

The ability of cells to decorate glycosaminoglycans (GAGs) with sulphate in highly specific patterns is important to extracellular matrix biogenesis and placing appropriate glycosulphated ligands on the cell surface. We have examined sulphate metabolism in two pancreatic duct epithelial cell

Mouse mastocytoma cells were cultured in medium containing [3H]GlcN and concentrations of [35S]sulphate varying from 0.01 to 0.5 mM. Intracellular [35S]sulphate incorporation increased severalfold from the lowest concentrations, reaching a maximum at 0.1-0.2 mM, whereas incorporation of [3H]hexosamine remained constant
