The proteoglycan superfamily now contains more than 30 full-time molecules that fulfill a variety of biological functions. Proteoglycans act as tissue organizers, influence cell growth and the maturation of specialized tissues, play a role as biological filters and modulate growth-factor activities, regulate collagen fibrillogenesis and skin tensile strength, affect tumor cell growth and invasion, and influence corneal transparency and neurite outgrowth. Additional roles, derived from studies of mutant animals, indicate that certain proteoglycans are essential to life whereas others might be redundant. The review focuses on the most recent genetic and molecular biological studies of the matrix proteoglycans, broadly defined as proteoglycans secreted into the pericellular matrix. Special emphasis is placed on the molecular organization of the protein core, the utilization of protein modules, the gene structure and transcriptional control, and the functional roles of the various proteoglycans. ...
Purified proteoglycan subunits from human articular, bovine articular and nasal cartilages, and a rat chondrosarcoma were phosphorylated in vitro by beef heart cAMP-dependent protein kinase in the presence of gamma 32P-ATP. In these experiments, a maximum of 1.7 moles of 32P were incorporated per mole of proteoglycan from human cartilage. Phosphorylation was dependent on the presence of cAMP. Analysis by autoradiography revealed that serine residues in the core protein of the proteoglycan were the sites of phosphorylation. Treatment of proteoglycan subunits with chondroitinase ABC and alkaline phosphatase prior to reaction with cAMP-dependent protein kinase increased the incorporation of 32P by 12-30% when compared with untreated proteoglycans. These data indicate that proteoglycans in cartilage can be phosphorylated by cAMP-dependent protein kinase.

Transforming growth factor beta (TGF-beta) is a polypeptide growth factor that affects the accumulation of extracellular matrix by many cell types. We have examined the ability of mouse mammary epithelial (NMuMG) cells to respond to TGF-beta and assessed the effect of the growth factor on the expression of their cell surface heparan sulfate/chondroitin sulfate hybrid proteoglycan. NMuMG cells respond maximally to 3 ng/ml TGF-beta and the response is consistent with occupancy of the type III receptor. However, cells that are polarized, as shown by sequestration of the cell surface PG at their basolateral surfaces, must have the growth factor supplied to that site for maximal response. Immunological quantification of proteoglycan core protein on treated cells suggests that the cells have an unchanging number of this proteoglycan at their cell surface. Nonetheless, metabolic labeling with radiosulfate shows a approximately 2.5-fold increase in 35SO4-glycosaminoglycans in this proteoglycan fraction, ...

Objective: Examine effects of insulin-like growth factor 1 (IGF1), transforming growth factor β2 (TGFβ2) and fibroblast growth factor 2 (FGF2) on proteoglycan and collagen network and biomechanical properties of the newly formed cartilage matrix. Methods: Bovine articular chondrocytes were cultured in alginate beads for 3 weeks with or without FGF2, TGFβ2 or IGF1 in the presence of 10% FCS. Proteoglycan content, collagen content, hydroxylysylpyridinoline cross-links and overall matrix metalloproteinase (MMP) activity in the culture medium were measured. Alginate disks cultured for 5 weeks were used to evaluate the effect of growth factors on mechanical properties of the construct by determining the equilibrium aggregate modulus and secant modulus. Results: IGF1 increased collagen and proteoglycan deposition. FGF2 mainly decreased collagen deposition and TGFβ2 proteoglycan deposition. A decrease in cross-links was observed in matrix produced by chondrocytes cultured in the presence of TGFβ2. ...
Versican is present throughout advanced lesions of atherosclerosis as well. A large CSPG has been isolated from atherosclerotic lesions of large hydrodynamic size with a core protein ranging in size from 160 to 245 and containing a mixture of chondroitin 6-sulfate and chondroitin 4-sulfate chains with chondroitin 6-sulfate predominating.20,35-38 Versican is prominent at the edges of the necrotic core in more advanced lesions of atherosclerosis and in close proximity to deposited lipoproteins,25,29,30 suggesting a role in the retention of lipoproteins in the vessel wall. The response to retention hypothesis of atherosclerosis,39 based on pioneering work performed in the 1970s and 1980s40-44 invokes a critical role in atherogenesis for the retention of lipoproteins by ECM proteoglycans. A number of studies have shown that versican as well as other proteoglycans such as biglycan are associated with lipoprotein deposits in human atherosclerotic lesions25,27,29,31 and in lipid induced lesions in ...

Proteoglycans Proteoglycans are molecules composed of a polypeptide and one or several sulfated glycosaminoglycans attached by chemical bindings. They are found in every animal tissue. Almost every cell may synthesize proteoglycans, and then they are released, incorporated in the plasma membrane or stored in internals vesicles. They are essential molecules of the pericellular space. Proteoglycans are assembled inside the cell. The polypeptide is synthesized in the endoplasmic reticulum, where some monosaccharides are also added. However, the elongation of the glycosaminoglycan chains, as well as the addition of sulfate groups, occurs in the trans domain of the Golgi complex. Most of the proteoglycans are exocytosed to the extracellular space, but some of them will be part of the plasma membrane, where they are inserted among the fatty acid chains of lipids thanks to a sequence of hydrophobic amino acids of the polypeptide Different proteoglycans show different amino acid sequence and polypeptide ...
NG2/CSPG4 transmembrane proteoglycan (PG) is a multivalent cell surface macromolecule whose impact on tumour growth and dissemination has been extensively documented in a variety of tumours and animal models. The PG is abundantly expressed in numerous soft-tissue sarcoma subtypes where it tightly links to disease progression and evolvement of metastases.

Proteoglycans have been implicated in the invagination and formation of various embryonal cavitied primordia. In this paper the expression of chondroitin sulphate proteoglycan is analysed (CSPG) in the lens primordium during lens vesicle formation, and demonstrate that this proteoglycan has a speci®c distribution pattern with regard to invagination and fusion processes in the transformation of placode into lens vesicle. More speci®cally, CSPG was detached in: (1) the apical surface of lens epithelial cells, where early CSPG expression was observed in the whole of the lens placode whilst in the vesicle phase it was restricted to the posterior epithelium; (2) intense CSPG expression in the basal lamina, which remained constant for the entire period under study; (3) CSPG expression in the intercellular spaces of the lens primordium epithelium, which increased during the invagination of the primordium and which at the vesicle stage was more evident in the posterior epithelium; and (4) CSPG ...
The molecule neuron-glia 2 (NG2) is a transmembrane chondroitin sulphate proteoglycan that is present on a distinct population of glial cells in the central nervous system (eNS). NG2 has been used to identify this subgroup of cells as an additional major glial cell population, in addition to, oligodendrocytes, astrocytes, ependymal cells and microglia. In the adult brain, these cells retain the ability to differentiate into oligodendrocytes and astrocytes. NG2 is often re-expressed by brain tumours and has been found to have increased expression levels in the high grade glioma and glioma-derived cell lines. Within the scope of this thesis it has been demonstrated that culture conditions (different media and serum supplementation) influence expression of NG2 and other antigens on glioma cell cultures. Seven cell lines covering a range of histopathological diagnoses have been fully characterised with regard to their antigenic expression profiles. With one cell line in particular, UP AB, the ...
The transforming growth factor-beta (TGF-beta) receptor type III is a low abundance cell surface component that binds TGF-beta 1 and TGF-beta 2 with high affinity and specificity, and is present in many mammalian and avian cell types. Type III TGF-beta receptors affinity-labeled with 125I-TGF-beta migrate in sodium dodecyl sulfate-polyacrylamide electrophoresis gels as diffuse species of 250-350 kDa. Here we show that type III receptors deglycosylated by the action of trifluoromethanesulfonic acid yield affinity-labeled receptor cores of 110-130 kDa. This marked decrease in molecular weight is also achieved by combined treatment of type III receptors with heparitinase and chondroitinase ABC. Digestion of receptor-linked glycosaminoglycans by treatment of intact cell monolayers with heparitinase and chondroitinase does not prevent TGF-beta binding to the type III receptor core polypeptide and does not release the receptor polypeptide from the membrane. The type III TGF-beta receptor binds tightly to DEAE
Proteoglycans metabolically labelled with [35S]sulphate and [3H]glucosamine or [3H]leucine were isolated from the incubation medium and cell layer of human adult mesangial cells and glomerular visceral epithelial cells using sequential DEAE chromatography purification steps followed by gel-filtration chromatography. The proteoglycan composition of each peak was analysed by treatment with HNO2, chondroitinase ABC or chondroitinase AC followed by chromatography on Sephadex G-50 columns. Heparan sulphate proteoglycan (HSPG) and dermatan sulphate proteoglycan were detected in both the culture medium and cell layer of mesangial cells. Culture medium of glomerular visceral epithelial cells contained HSPG and a second proteoglycan with the properties of a hybrid molecule containing HS and chondroitin sulphate (CS). The cell layer contained HSPG and CSPG. Detailed analysis of the hybrid molecule revealed that it had an apparent molecular mass of 400 kDa. SDS/PAGE of hybrid molecules, after treatment ...

N2 - Proteoglycan (PG) aggrecan, a major macromolecular component of cartilage, is highly immunogenic; it induces arthritis in genetically susceptible BALB/c mice. The present study maps the T-cell epitope repertoire of cartilage PG by identifying a total of 27 distinct T-cell epitopes. An epitope hierarchy, accounting for the different effector functions of PG-specific T cells, and determinant spreading, has been found. T-cell responses to four epitopes were associated with arthritis induction. Some of the T-cell epitopes were full T-cell activators, whereas a number of subdominant and cryptic epitopes proved to be partial activators in vitro, inducing either cytokine secretion or T-cell proliferation, but not ...

Biglycan is a small leucine-rich repeat proteoglycan (SLRP) which is found in a variety of extracellular matrix tissues, including bone, cartilage and tendon. In humans, biglycan is encoded by the BGN gene which is located on the X chromosome. The name "biglycan" was proposed in an article by Fisher, Termine and Young in an article in the Journal of Biological Chemistry in 1989 because the proteoglycan contained two GAG chains; formerly it was known as proteoglycan-I (PG-I). Biglycan consists of a protein core containing leucine-rich repeat regions and two glycosaminoglycan (GAG) chains consisting of either chondroitin sulfate (CS) or dermatan sulfate (DS), with DS being more abundant in most connective tissues. The CS/DS chains are attached at amino acids 5 and 10 in human biglycan. The composition of the GAG chains has been reported as varying according to tissue of origin. Non-glycanated forms of biglycan (no GAG chains) increase with age in human articular cartilage. The composition of GAG ...
Proteoglycans consist of a core protein and an associated glycosaminoglycan (GAG) chain of heparan sulfate, chondroitin sulfate, dermatan sulfate or keratan sulfate, which are attached to a serine residue. The core proteins of cell surface proteoglycans may be transmembrane, e.g., syndecan, or GPI-anchored, e.g., glypican. Many different cell surface and matrix proteoglycan core proteins are expressed in the mammary gland and in mammary cells in culture. The level of expression of these core proteins, the structure of their GAG chains, and their degradation are regulated by many of the effectors that control the development and function of the mammary gland. Regulatory proteins of the mammary gland that bind GAG include many growth factors and morphogens (fibroblast growth factors, hepatocyte growth factor/scatter factor, members of the midkine family, wnts), matrix proteins (collagen, fibronectin, and laminin), enzymes (lipoprotein lipase) and microbial surface proteins. Structural diversity ...
Proteoglycans are proteins that are heavily glycosylated. The basic proteoglycan unit consists of a "core protein" with one or more covalently attached glycosaminoglycan (GAG) chain(s). The point of attachment is a serine (Ser) residue to which the glycosaminoglycan is joined through a tetrasaccharide bridge (e.g. chondroitin sulfate-GlcA-Gal-Gal-Xyl-PROTEIN). The Ser residue is generally in the sequence -Ser-Gly-X-Gly- (where X can be any amino acid residue but proline), although not every protein with this sequence has an attached glycosaminoglycan. The chains are long, linear carbohydrate polymers that are negatively charged under physiological conditions due to the occurrence of sulfate and uronic acid groups. Proteoglycans occur in the connective tissue. Proteoglycans are categorized by their relative size (large and small) and the nature of their glycosaminoglycan chains. Types include: Certain members are considered members of the "small leucine-rich proteoglycan family" (SLRP). These ...
The cornea is the primary refractive element of the eye and is also fundamental to the protection of the visual system. Collagen is the major constituent of the cornea, where it is organised in a lattice that enables corneal transparency. Proteoglycan macromolecules are thought to regulate the diameter and spatial order of collagen fibrils in the cornea, which are both pre-requisites for corneal transparency, although the mechanisms by which they organise fibrils are not fully elucidated. This investigation examined the morphology, morphometry and organisation of proteoglycans three-dimensionally, in both normal and genetically altered mouse corneas, to gain a greater understanding of proteoglycan structure-function relationships. In summary, we found that proteoglycans are primarily responsible for the remarkable collagen organisation in the mouse cornea, which allows for corneal transparency. The self- association of proteoglycans into complexes is likely to result in a robust attachment of ...

Protein-bound polysaccharide-K (PSK) is a hot water extract from Trametes versicolor mushroom. It has been used traditionally in Asian countries for its immune stimulating and anti-cancer effects. We have recently found that PSK can activate Toll-like receptor 2 (TLR2). TLR2 is highly expressed on dendritic cells (DC), so the current study was undertaken to evaluate the effect of PSK on DC activation and the potential of using PSK as a vaccine adjuvant. In vitro experiments using mouse bone marrow-derived DC (BMDC) demonstrated that PSK induces DC maturation as shown by dose-dependent increase in the expression of CD80, CD86, MHCII, and CD40. PSK also induces the production of multiple inflammatory cytokines by DC, including IL-12, TNF-α, and IL-6, at both mRNA and protein levels. In vivo experiments using PSK as an adjuvant to OVAp323-339 vaccine showed that PSK as adjuvant leads to enlarged draining lymph nodes with higher number of activated DC. PSK also stimulates proliferation of ...
Radiobiology Laboratory, St. Marys Medical Center, California Pacific Medical Center Research Institute, San Francisco 94118, USA.. Abstract. Polysaccharide-K (polysaccharide-Kureha; PSK), also known as krestin, is a unique protein-bound polysaccharide, which has been used as a chemoimmunotherapy agent in the treatment of cancer in Asia for over 30 years. PSK and Polysaccharopeptide (PSP) are both protein-bound polysaccharides which are derived from the CM-101 and COV-1 strains of the fungus Coriolus versicolor by Japanese and Chinese researchers, respectively. Both polysaccharide preparations have documented anticancer activity in vitro, in vivo and in human clinical trials, though PSK has been researched longer and has therefore undergone more thorough laboratory, animal and clinical testing. Several randomized clinical trials have demonstrated that PSK has great potential as an adjuvant cancer therapy agent, with positive results seen in the adjuvant treatment of gastric, esophageal, ...
Proteoglycans (PGs) are one of the major components in the extracellular matrix (ECM) of cartilage, and are negatively charged due to the charged groups attached to their backbone (i.e., fixed charge groups). PGs play substantial roles in the mechanical, biotransport and electrical events within the tissue.3,7 More specifically, swelling pressure generated by the interaction between fixed charge groups and ionic interstitial fluid enhances cartilages capacity of load-bearing. In addition, biotransport properties (e.g., hydraulic permeability) and electrical properties (e.g., electrical conductivity) have been shown to be affected by water content (i.e., porosity) and fixed charge density (FCD).2-4 The alteration of proteoglycan content will affect the tissue FCD and water content, which could cause the changes in biomechanical, biotransport and electrical properties of the cartilage. The relationship between the PG content and biomechanical properties has been widely studied,6,8 but the ...

Apocynin, an inhibitor of NADPH-oxidase, is known to partially reverse the inflammation-mediated cartilage proteoglycan synthesis in chondrocytes. More recently, it was reported that apocynin prevents cyclooxygenase (COX)-2 expression in monocytes. The present study aimed to investigate whether these in vitro features of apocynin could be confirmed in vivo. In a mouse model of zymosan-induced acute arthritis apocynin was administered orally (0, 3.2, 16 and 80 microg/ml in the drinking water) and the effects on cartilage proteoglycan synthesis were monitored. In a mouse model of zymosan-induced inflammation of the ears apocynin was administered orally (14 mg/kg/day by gavage) and the effects on ear swelling and ex vivo produced prostaglandin E2 (PGE2) by lipopolysaccharide (LPS)-stimulated blood cells were measured. In this study, ibuprofen was used as a positive control (50 mg/kg/day by gavage) and animals received vehicle as a negative control. Apocynin dose-dependently reversed the inhibition ...

Glucosamine stimulates the cartilage cells to produce the needed proteoglycans, large molecules that give cartilage strength and resilience, allowing it to stretch and then resume its normal form as the joints moves. A deficiency of glucosamine will result in low levels of proteoglycans that are inadequate in maintaining healthy joints. Glucosamine is one of the main ingredients of the synovial fluid that lubricates and provides nutrients for the joint structures. This synovial fluid reduces friction in the joints allowing for effortless motion. It not only lubricates the joints but it also acts as a comfortable shock absorber. Furthermore, glucosamine inhibits several enzymes whose job is the break down of old proteoglycan molecules nearing the end of their normal life span. In summary, glucosamine not only stimulates the production of cartilage but it can also improve joint function, increase flexibility, mobility, and help reduce the pain of those suffering from osteoarthritis ...
