Glycosaminoglycans Metabolism

Isolation and characterization of glycosaminoglycans in human plasma.

We have described methodology for the isolation and quantitation of glycosaminoglycans present in human plasma. Plasma glycosaminoglycans can be quantitatively adsorbed on a DEAE-Sephacel ion exchanger and eluted with a salt gradient as two groups: a low-charge fraction and a high-charge fraction. The low-charge fraction consists of chondroitin sulfate with a low sulfate content and the high-ch...

Metabolism of proteoglycans and glycosaminoglycans in cultivated fibroblasts.

Effect of 2-deoxy-D-glucose on metabolism of glycosaminoglycans in normal and hypercholesterolemic rats.

Carbohydrates are the integral parts of glyco-conjugates and play an important role in cellular functions. 2-Deoxy-D-glucose (2-dGlc) is a sugar analogue of glucose and mannose and is reported to inhibit the lipid-linked saccharide formation involved in N-linked glycosylation of proteins. Administration of 2-dGlc (1 mg/100 g body weight) produced a decrease in the tissue total glycosaminoglycan...

Human milk glycosaminoglycans: the state of the art and future perspectives

Recently, a complete characterization and detailed evaluation of the glycosaminoglycans of human milk were performed. The total glycosaminoglycans content in milk from healthy mothers having delivered term or preterm newborns showed a constant pattern which was essentially composed of two main polysaccharides: chondroitin sulfate (60-70%) and heparin (30-40%). Moreover, considerable variations ...

INFLUENCE OF GLYCOSAMINOGLYCANS ISOLATED FROM THE RAT LIVER WITH VARIOUS STAGES OF CARBON TETRACHLORIDE-INDUCED FIBROSIS UPON COLLAGEN FIBRILLOGENESIS IN VITRO

The influence of glycosaminoglycans (GAG) on collagen fibrillogenesis in vitro was investigated. GAG and collagen were isolated from the liver of rats treated with carbon tetrachloride at various time intervals (3-16 weeks). It was found that GAG obtained from the fibrotic liver accelerated collagen fibril formation. This effect was more evident in a solution of type I collagen than type II...
