Radioimmunoassay of Proteoglycans
Journal of Immunoassay, 1984Human articular cartilage proteoglycan monomers (PG) were purified and used for developing a radioimmunoassay. Its analytical sensitivity is 0.6 ng/tube and its clinical sensitivity is 20 microliter/tube for serum and 0.12 microliter/tube for synovial fluid.

Interaction of bone proteoglycans and proteoglycan components with hydroxyapatite
Biochimica et Biophysica Acta (BBA) - General Subjects, 2001The small leucine-rich proteoglycans (SLRPs) of bone interact with hydroxyapatite (HAP) and are proposed to play an important role in the regulation of the mineralisation process. The present study has examined the interaction of bone SLRPs, purified, liberated bone glycosaminoglycan (GAG) chains and core proteins, as well as commercial chondroitin 4 ...

Emerging proteoglycans and proteoglycan-targeted therapies in rheumatoid arthritis
American Journal of Physiology-Cell Physiology, 2022Rheumatoid arthritis (RA) is a common autoimmune disease that causes inflammation of the joints and damage to the cartilage and bone. The pathogenesis of RA is characterized in many patients by the presence of antibodies against citrullinated proteins.

Bulletin of Experimental Biology and Medicine, 1996
Studies of proteoglycans for their capacity to perform the function of steric exclusion of cells are reviewed. The ability of the proteoglycans hyaluronic acid and protein-chrondroitinkeratosulfate and their aggregates to effect cell aggregation and steric exclusion is determined by the structure of glycosaminoglycan components and the amount of ...

Cytokines play an important regulatory role in the metabolism of proteoglycans. Proteoglycans are found in plasma membranes, but predominantly in the extra-cellular matrix. In the latter they are quantitatively and qualitatively essential components. Especially in a tissue like cartilage without any blood vessels, the cells are dependent on cytokines ...

The Immunology of Proteoglycans
Connective Tissue Research, 1982This discussion will touch on some of the central features of proteoglycan (PG) immunology and suggest that despite the recent introduction of very sophisticated immunochemical techniques, this remains a problematic field. As I shall indicate, there are difficulties in understanding the immunological properties of PGs which are due to the nature of PG,

CANCER AND METASTASIS REVIEW, 1988
There is a growing realization that the whole tumor cell-matrix complex must be investigated in order to fully understand the process of cancer growth and metastasis. Proteoglycans are intrinsic constituents of the cell surface, extracellular matrix, and basement membrane, three logistically and functionally important structures involved in most ...

Proteoglycan Isolation and Analysis
Current Protocols in Cell Biology, 2000AbstractProteoglycans can be difficult molecules to isolate and analyze due to large mass, charge, and tendency to aggregate or form macromolecular complexes. This unit describes detailed methods for purification of matrix, cell surface, and cytoskeleton‐linked proteoglycans.

Tenascin and proteoglycans: the role of tenascin and proteoglycans in canine tumours
Research in Veterinary Science, 2002Tenascin is a high molecular weight, extracellular matrix glycoprotein, subject to complex spatial and temporal patterns of expression during embryogenesis, wound healing and neoplastic processes. Proteoglycans are complex macromolecules, containing one or more glycosaminoglycans attached to a core protein, which are involved in cell-cell and cell ...
