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

4-Methylumbelliferyl-beta-D-xyloside (Xyl-MU) was added to the medium of cultured human skin fibroblasts. After incubation, the culture medium was pooled, and the Xyl-MU-induced oligosaccharides in the medium were purified by gel filtration chromatography. A novel Xyl-MU derivative was obtained, in addition

Human skin fibroblasts were cultured in the presence of 4-methylumbelliferyl-beta-D-xyloside (Xyl-MU) using a mass-culture system with a microcarrier. The structures of Xyl-MU-induced sugars purified from the dialysable fraction of the incubation medium were investigated. In addition to glycosaminoglycans the elongation

The importance of the pathological changes in proteoglycans has driven the need to study and design novel chemical tools to control proteoglycan synthesis. Accordingly, we tested the fluorinated analogue of glucosamine (4-fluoro-N-acetyl-glucosamine (4-F-GlcNAc)) on the synthesis of heparan sulfate (HS)
