Although the changes in urinary glycosaminoglycans have been investigated in several endocrinopathies, no information was hitherto available on the content and composition of urinary glycosaminoglycans in hypothyroidism. Urinary glycosaminoglycans were therefore investigated in patients with hypothyroidism and in healthy subjects. The total daily excretion of urinary glycosaminoglycans was foun...

Sulfated glycosaminoglycans were extracted from arteriosclerotic and adjacent nonarteriosclerotic areas of human aortas from persons ages 28 to 83 years; the glycosaminoglycans were compared with the cholesterol and triglyceride content of the tissues. Sulfated glycosaminoglycans were isolated after proteolytic digestion of defatted arterial tissue and were quantified after reductive labeling w...

Herpes simplex virus type 2 (HSV-2) interacts with cell surface glycosaminoglycans during virus attachment. Glycoprotein B of HSV-2 can potentially mediate the interaction between the virion and cell surface glycosaminoglycans. To determine the specificity, kinetics, and affinity of these interactions, we used plasmon resonance-based biosensor technology to measure HSV-2 glycoprotein binding to...

We have characterized sulfated glycosaminoglycans from ovaries of the blood-sucking insect Rhodnius prolixus, and determined parameters of their synthesis and distribution within this organ by biochemical and histochemical procedures. The major sulfated glycosaminoglycan is heparan sulfate while chondroitin 4-sulfate is a minor component. These glycosaminoglycans are concentrated in the ovarian...

Lowe (oculocerebrorenal) syndrome (LS) is an X-linked disorder characterized by congenital cataracts, generalized hypotonia, mental retardation, and renal Fanconi syndrome. The basic defect remains unknown, but the possibility that fibroblasts express reduced sulfation of glycosaminoglycans has been studied in several laboratories. A mechanism involving overproduction of an enzyme (nucleotide p...

Non-pregnant and pregnant rats of known gestational age were killed at intervals and their uterine cervices were excised and digested with papain. Glycosaminoglycans thus extracted were separated by cellulose acetate electrophoresis and stained with Alcian Blue. Glycosaminoglycans were identified by comparison with standards and by serial degradation with chondroitin ABC lyase, butyl nitrite an...

Glycosaminoglycans are unbranched polysaccharides composed of repeating units of alternating uronic acids and amino sugars. Most glycosaminoglycans are covalently attached to core proteins to form proteoglycans. Posttranslational modifications result in specific motifs that bind to a large variety of ligands, thus regulating growth factor signaling, cellular behavior, inflammation, angiogenesis...

Of a range of glycosaminoglycans, heparin and heparan sulphate were the most effective inhibitors in vitro of CaCO3 (calcite) crystallization as assayed by conductimetric measurements. The possible role of such glycosaminoglycans in modulating calcium-salt crystallizations in vivo is discussed.
