Mucopolysaccharide accumulation in cultured skin fibroblasts derived from patients with mucolipidosis IV. 1977

G Bach, and M Ziegler, and G Kohn, and M M Cohen

Increased concentrations of total sulfated mucopolysaccharides (MPS), threefold, and hyaluronic acid (HA), 10-fold, were found in ML IV fibroblast extracts when compared to normal controls. Such accumulations altered the distribution of MPS:HA comprised 70% of total MPS in ML IV but only 30% in control cells. Intracellular sulfated MPS was observed accumulating almost linearly in ML IV fibroblasts. "Pulse-chase" experiments indicate that both HA and the sulfated MPS remain in the ML IV cells for long periods of time; in control cells, they are rapidly removed as low molecular weight, dialyzable fragments. These data suggest that the MPS accumulation in ML IV fibroblasts, is the consequence of a catabolic block, probably involving the lysosome.

UI MeSH Term Description Entries
D009081 Mucolipidoses A group of inherited metabolic diseases characterized by the accumulation of excessive amounts of acid mucopolysaccharides, sphingolipids, and/or glycolipids in visceral and mesenchymal cells. Abnormal amounts of sphingolipids or glycolipids are present in neural tissue. INTELLECTUAL DISABILITY and skeletal changes, most notably dysostosis multiplex, occur frequently.

D006025 Glycosaminoglycans Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).
