The effect of W. somnifera on glycosaminoglycan synthesis in the granulation tissue of carrageenin-induced air pouch granuloma was studied. W. somnifera was shown to exert significant inhibitory effect on incorporation of /sup 35/S into the granulation tissue. The uncoupling effect on oxidative phosphorylation (ADP/O ratio reduction) was also observed in the mitochondria of granulation tissue. Further, Mg/sup 2 +/ dependent ATPase activity was found to be influenced by W. somnifera. W. somnifera also reduced the succinate dehydrogenase enzyme activity in the mitochondria of granulation tissue. ...

TY - JOUR. T1 - The effect of dexamethasone on glycosaminoglycans of human trabecular meshwork in perfusion organ culture. AU - Johnson, D. H.. AU - Bradley, J. M B. AU - Acott, Ted. PY - 1990. Y1 - 1990. N2 - The effect of dexamethasone treatment on glycosaminoglycans (GAG) in the human trabecular meshwork was studied by placing 20 pairs of eyes in perfusion organ culture. One eye received 550 nM dexamethasone in addition to culture medium; the fellow eye received culture medium only. 3H-glucosamine and 35S-sulfate were added to the medium for the final 48 hr of culture. The meshwork was then dissected, and the GAGs were isolated and subjected to sequential enzymatic degradation. Active labeling of hyaluronic acid, chondroitin sulfate, dermatan sulfate, keratan sulfate, and heparan sulfate was found in both control and steroid-treated eyes. Dexamethasone-treated eyes had an average 92% increase in the 3H-glucosamine incorporation rate in the undigestible GAG residue fraction after 14-21 days ...

Bovine heart valves metabolize up to 96% of exogenous |sup|14|/sup|C-glucose to lactate when incubated in vitro under appropriate conditions. Small proportions of the |sup|14|/sup|C-radioactivity are incorporated into glycogen, glycosaminoglycans and lipids and are oxydized to |sup|14|/sup|CO|sub|2|/sub|. Difference between the valves of the left ventricle (aortic and mitral valve) and of the right ventricle (pulmonary and tricuspid valve) were found in the rate of glycolysis as well as in the collagen, glycogen and glycosaminoglycan content. The in vitro incorporation of [U-|sup|14|/sup|C] glucose radioactivity into the total glycosaminoglycans resulted in a specific labelling of hyaluronic acid, dermatan sulfate and chondroitin sulfate, but the specific radioactivities of the individual glycosaminoglycans and their relative rates of biosynthesis differed markedly. The relative rates of biosynthesis were 2.9-7.6 for hyaluronate, 1.0 for dermatan sulfate and 0.26-0.59 for chondroitin sulfate. After

Cartilage tissue specimens were obtained from the flexor surface of the navicular bone and distal radiocarpal bone articular surface (controls) from 8 horses 2 to 5 years old. Water, DNA, total collagen, total glycosaminoglycans, chondroitin sulphate, and keratan sulphate contents were determined. The results from each site were compared and the differences were analyzed by paired t-test (P < 0.05). Significant differences were determined between the water content of the navicular bone flexor surface cartilage (68.32± 3.46 % ) and the distal radiocarpal bone articular surface cartilage (60.60± 4.09%). The total DNA content, total glycosaminoglycan content, total chondroitin sulphate content, and total keratan sulphate for the flexor surface of the navicular bone was: 524.51± 92.89 ng, 0.1533± 0.0338 mg, 0.1018± 0.0197 mg 0.0800± 0.0176 mg, and 0.0092± 0.0037 mg per mg of dry weight cartilage, respectively.

BBM restored cell surface GAGs and attenuated endothelial inflammation in diabetic HAECs. Blueberry might complement conventional therapies to improve vascular complications in diabetes.

Xenopus laevis is an excellent animal for analyzing early vertebrate development. Various effects of glycosaminoglycans (GAGs) on growth factor-related cellular events during embryogenesis have been demonstrated in Xenopus. To elucidate the relationship between alterations in fine structure and changes in the specificity of growth factor-binding during Xenopus development, heparan sulfate (HS) and chondroitin/dermatan sulfate (CS/DS) chains were isolated at four different embryonic stages and their structure and growth factor-binding capacities were compared. The total amounts of both HS and CS/DS chains decreased from the pre-midblastula transition to the gastrula stage, but increased exponentially during the following developmental stages. The length of HS chains was not significantly affected by development, whereas that of CS/DS chains increased with development. The disaccharide composition of GAGs in embryos also changed during development. The degree of sulfation of the HS chains ...

Loss of glycosaminoglycan (GAG) chains of proteoglycans (PGs) is an early event of osteoarthritis (OA) resulting in cartilage degradation that has been previously demonstrated in both huma and experimental OA models. However, the mechanism of GAG loss and the role of xylosyltransferase-I (XT-I) that initiates GAG biosynthesis onto PG molecules in the pathogenic process of human OA are unknown. In this study, we have characterized XT-I expression and activity together with GAG synthesis in human OA cartilage obtained from different regions of the same joint, defined as normal, late-stage or adjacent to late-stage. The results showed that GAG synthesis and content increased in cartilage from areas flanking OA lesions compared to cartilage from macroscopically normal unaffected regions, while decreased in late-stage OA cartilage lesions. This increase in anabolic state was associated with a marked upregulation of XT-I expression and activity in cartilage next to lesion while a decrease in the

Background-Heart failure (HF) is a leading cause of mortality and morbidity, and the search for novel therapeutic approaches continues. In the monogenic disease mucopolysaccharidosis (MPS) VI, loss of function mutations in arylsulfatase B (ASB) leads to myocardial accumulation of chondroitin sulfate (CS) glycosaminoglycans (GAGs), manifesting as a myriad of cardiac symptoms. Here, we studied changes in myocardial CS in non-MPS failing hearts, and assessed its generic role in pathological cardiac remodeling. Methods-Healthy and diseased human and rat left ventricles were subjected to histological and immuno-staining methods to analyze for GAG distribution. GAGs were extracted and analyzed for quantitative and compositional changes using Alcian Blue assay and liquid chromatography mass spectrometry. Expression changes in 20 CS-related genes were studied in three primary human cardiac cell types and THP-1 derived macrophages under each of 9 in vitro stimulatory conditions. In two rat models of ...

Metachromasia (var. metachromasy) is a characteristic change in the color of staining carried out in biological tissues, exhibited by certain dyes when they bind to particular substances present in these tissues, called chromotropes. For example, toluidine blue becomes dark blue (with a colour range from blue-red dependent on glycosaminoglycan content) when bound to cartilage. Other widely used metachromatic stains are the haematological Giemsa and May-Grunwald stains that also contain thiazine dyes. The white cell nucleus stains purple, basophil granules intense magenta, whilst the cytoplasms (of mononuclear cells) stains blue. The absence of color change in staining is named orthochromasia. The underlying mechanism for metachromasia requires the presence of polyanions within the tissue. When these tissues are stained with a concentrated basic dye solution, such as toluidine blue, the bound dye molecules are close enough to form dimeric and polymeric aggregates. The light absorption spectra of ...

Heparan sulfate (HS) and heparin (Hep) are glycosaminoglycans with repeating disaccharide units that consist of alternating residues of alpha-D-glucosamine (GlcN) and uronic acid, the latter being either beta-D-glucuronic acid (GlcA) or alpha-L-iduronic acid (IdoA). In these sugar residues, sulfation modification may be performed at various positions. Structural studies show that Hep possesses a higher degree of sulfation than HS. The biosynthesis of HS/Hep occurs with the addition of the first GlcNAc residue by EXTL3 glycosyltransferase after completion of tetrasaccharide linkage region attached to serine residue of a core protein. The chain polymeraization is then catalyzed by EXT1 and EXT2 transferases. As the chain polymerizes, HS/Hep undergoes a series of modification reactions including N-deacetylation, N-sulfation, epimerization, and subsequently O-sulfation. As final products of biosynthesis, HS is present in the form of hepran sulfate proteoglycan (HSPG) whereas Hep exists as a sugar ...

Protein transduction domains (PTDs) are powerful nongenetic tools that allow intracellular delivery of conjugated cargoes to modify cell behavior. Their use in biomedicine has been hampered by inefficient delivery to nuclear and cytoplasmic targets. Here we overcame this deficiency by developing a series of novel fusion proteins that couple a membrane-docking peptide to heparan sulfate glycosaminoglycans (GAGs) with a PTD. We showed that this GET (GAG-binding enhanced transduction) system could deliver enzymes (Cre, neomycin phosphotransferase), transcription factors (NANOG, MYOD), antibodies, native proteins (cytochrome C), magnetic nanoparticles (MNPs), and nucleic acids [plasmid (p)DNA, modified (mod)RNA, and small inhibitory RNA] at efficiencies of up to two orders of magnitude higher than previously reported in cell types considered hard to transduce, such as mouse embryonic stem cells (mESCs), human ESCs (hESCs), and induced pluripotent stem cells (hiPSCs). This technology represents an ...

Adhesion to extracellular matrix (ECM) components has been implicated in the proliferative and invasive properties of tumor cells. We investigated the ability of C6 glioma cells to attach to ECM components in vitro and described the regulatory role of glycosaminoglycans (GAGs) on their adhesion to the substrate, proliferation and migration. ECM proteins (type IV collagen, laminin and fibronectin) stimulate rat C6 glioma cell line adhesion in vitro, in a dose-dependent manner. The higher adhesion values were achieved with type IV collagen. Exogenous heparin or chondroitin sulfate impaired, in a dose-dependent manner the attachment of C6 glioma cell line to laminin and fibronectin, but not to type IV collagen. Dextran sulfate did not affect C6 adhesion to any ECM protein analyzed, indicating a specific role of GAGs in mediating glioma adhesion to laminin and fibronectin. GAGs and dextran sulfate did not induce C6 glioma detachment from any tested substrate suggesting specific effect in the initial step of

Description: The formation of a cross-link between peptide chains mediated by a chondroitin 4-sulfate glycosaminoglycan that originates from a typical O-glycosidic link to serine of one chain; the other chain is esterified, via the alpha-carbon of its C-terminal Asp, to C-6 of an internal N-acetylgalactosamine of the glycosaminoglycan chain.. ...

Controlled release systems for therapeutic molecules are vital to allow the sustained local delivery of their activities which direct cell behaviour and enable novel regenerative strategies. Direct programming of cells using exogenously delivered transcription factors can by-pass growth factor signalling but there is still a requirement to deliver such activity spatio-temporally. We previously developed a technology termed GAG-binding enhanced transduction (GET) to efficiently deliver a variety of cargoes intracellularly, using GAG-binding domains which promote cell targeting, and cell penetrating peptides (CPPs) which allow cell entry. Herein we demonstrate that GET system can be used in controlled release systems to mediate sustained intracellular transduction over one week. We assessed the stability and activity of GET peptides in poly(dl-lactic acid-co-glycolic acid) (PLGA) microparticles (MPs) prepared using a S/O/W double emulsion method. Efficient encapsulation (∼65%) and tailored ...

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 ...

Chemokines are small immune system proteins mediating leukocyte migration and activation, and are important in many aspects of health and diseases. Some chemokines also have the ability to block HIV-1 infection by binding to the HIV-1 co-receptors CCR5 (CC chemokine receptor 5) and CXCR4 (CXC chemokine receptor 4). The first part of this work is to determine the mechanism of action of a human herpesvirus-8 encoded viral chemokine analog vMIP-II (viral macrophage inflammatory protein-II) by characterizing its interactions with endothelial surface glycosaminoglycans (GAGs) and cell surface receptors. Nuclear magnetic resonance (NMR), mutagenesis and molecular-docking were conducted and results show that vMIP-II tightly binds glycosaminoglycans using residues distributed along one face of the protein, such as R18, R46 and R48, and that there is a shift in the GAG binding site between the monomer and dimer form of vMIP-II where the N-terminus is involved in GAG binding for the dimer. This study, for ...

My research is focused on the elucidation of the structure and function of connective tissue macromolecules in health and disease. I have a special interest in the study of glycosaminoglycans (GAGs) and the proteoglycans (PGs) to which they are attached.. Glycosaminoglycans are a class of sulphated polysaccharides found in association with a protein core to form a PG. The structural diversity of GAGs is large and as novel systems are being examined and increasingly sensitive methods of detection and analysis are being used this diversity is expanding.. Important functionality is associated with GAGs and PGs and my work seeks to identify and examine these functions and their relationship with structural motifs especially within the GAG chondroitin / dermatan sulphate.. My work involves the development of GAG isolation and analysis methodologies and the application of these methods to several areas of investigation..

Hedgehog (Hh) morphogens play fundamental roles during embryogenesis and adulthood, in health and disease. Multiple cell surface receptors regulate the Hh signaling pathway. Among these, the glycosaminoglycan (GAG) chains of proteoglycans shape Hh gradients and signal transduction. We have determined crystal structures of Sonic Hh complexes with two GAGs, heparin and chondroitin sulfate. The interaction determinants, confirmed by site-directed mutagenesis and binding studies, reveal a previously not identified Hh site for GAG binding, common to all Hh proteins. The majority of Hh residues forming this GAG-binding site have been previously implicated in developmental diseases. Crystal packing analysis, combined with analytical ultracentrifugation of Sonic Hh-GAG complexes, suggests a potential mechanism for GAG-dependent Hh multimerization. Taken together, these results provide a direct mechanistic explanation of the observed correlation between disease and impaired Hh gradient formation. ...

The protein encoded by this gene is a member of the glucuronyltransferase gene family, enzymes that exhibit strict acceptor specificity, recognizing nonreducing terminal sugars and their anomeric linkages. This gene product catalyzes the formation of the glycosaminoglycan-protein linkage by way of a glucuronyl transfer reaction in the final step of the biosynthesis of the linkage region of proteoglycans. A pseudogene of this gene has been identified on chromosome 3. [provided by RefSeq, Dec 2013 ...

Background: Therapeutic strategies that successfully combine autologous micrografting and biodegradable scaffolds offer great potential for improved wound repair. In this study we evaluate the efficacy of a novel modification of a collagen-glycosaminoglycan scaffold (CGS) with autologous micrografts using a murine dorsal wound model.. Methods: db/db mice underwent a full thickness 1.0cm2 dorsal wound excision and were treated with a CGS, a modified CGS (CGS+MG) or simple occlusive dressing (Blank). The modified scaffold was created by harvesting full thickness micrografts and transplanting these into the CGS membrane. Parameters of wound healing, including cellular proliferation, collagen deposition, keratinocyte migration, and angiogenesis were assessed.. Results: The group treated with the micrograft-modified scaffold healed at a faster rate, showed greater cellular proliferation (63.2±27.3µm vs. 624.4±284.3µm, p,0.0001), collagen deposition (18.7±2.9 vs. 34.5±5.2%; p,0.0001), with ...

A process for preparing a crosslinked collagen-glycosaminoglycan composite material which comprises forming an uncrosslinked composite material from collagen and a glycosaminoglycan and contacting the uncrosslinked composite with a gaseous aldehyde until a crosslinked product having an Mc of from about 800 to about 60,000 is disclosed along with composite materials prepared by this process. Artificial skin produced by this process is more stable toward long-term storage than similar materials prepared using other methods of crosslinking.

Glycosaminoglycans (GAGs), the carbohydrate moieties of proteoglycans, are thought to be positive and negative regulators of axonal growth. The physiological role of GAGs is controversial as some studies have shown that GAGs inhibit cell adhesion and neurite elongation (Exp Neurol 109:111, 1990) whereas other studies have reported a growth stimulatory effect of GAGs (Development 114:17, 1992). These and other studies have examined the effects of GAGs using different types of neurons and different substrate conditions thereby making a direct comparison of the experimental data difficult. To resolve the controversy concerning the ability of exogenous GAGs to modulate neurite growth, we examined the effects of a panel of structurally different GAGs on the growth of postnatal rat cerebellar granule neurons and embryonic rat dorsal root ganglia (DRG) neurons on substrates of either laminin or the L1 glycoprotein. Here we show that chondroitin 4-sulfate (CS4), chondroitin 6-sulfate (CS6), and keratan ...

The physical properties of cartilage depend on electrostatic bonds between type II collagen fibrils, hyaluronan, and the sulfated GAGs on densely packed proteoglycans. Its semi-rigid consistency is attributable to water bound to the negatively charged hyaluronan and GAG chains extending from proteoglycan core proteins, which in turn are enclosed within a dense meshwork of thin type II collagen fibrils. The high content of bound water allows cartilage to serve as a shock absorber, an important functional role. ...

A method and a pharmaceutical composition for non-topical wound, scar and keloid treatment is described which contains cross-linked glycosaminoglycans and conventional pharmaceutical auxiliary and/or carrier substances. The pharmaceutical composition is preferably administered intralesionally e.g. by injection in the form of a gel containing water. The cross-linked glycosaminoglycans are also suitable for use as cosmetics and skin care products.

Mucopolysaccharidoses are a group of metabolic disorders characterized by the accumulation of GAGs (glycosaminoglycans, or mucopolysaccharides) due to the impaired functions of lysosomal enzymes. It is the mucopolysaccharides which help in building bones, cartilage, skin, tendons, corneas, and the fluid responsible for lubricating joints.

Treatment of vascular diseases should be based on established pathophysiological concepts, and this also applies to chronic venous disease (CVD). On the basis of the latest research in this field, this paper summarizes the most advanced pathophysiological knowledge regarding the hemodynamics of the large veins and of the microcirculation, the endothelial function and inflammation, and the use of sulodexide in the treatment of CVD. The emerging theories on the pathophysiology of CVD consider inflammation, endothelial glycocalyx dysfunction, and the consequent changes in the extracellular matrix to play key roles in the development of CVD, and support a renewed interest in the research and application of sulodexide. As part of active approach to the treatment of CVD including edema and trophic venous alterations, sulodexide could help to alleviate progressive signs and symptoms of disease in any clinical CEAP class of CVD, from C1 to C6.. ...

In the present study, we focused on the roles of the glycosaminoglycan component of the cell-surface glycome in modulating vasculogenesis. As the first step, we recapitulated vasculogenesis from ESC-EBs. The primary vascular plexus formed in the embryonic body undergoes remodeling from day 6 or 7 onward via sprouting angiogenesis.12,13 Interestingly, comparison of the compositional analysis of the cell-surface HSGAGs of a day 3 and a day 7 ESC-EB revealed distinct profiles that led to an increase in highly sulfated disaccharide residues with differentiation. These sulfate residues are introduced into the nascent polymer through a series of sequential enzyme-induced modifications. The bifunctional activity of the NDST family appears to be a key regulator in this process, because most of the other modifications, namely, C5 epimerization and 2O, 3O, and 6O sulfations, predominate around the N-sulfated regions. Interestingly, both mRNA transcripts and total NDST1 protein levels were upregulated ...

1] For drug development, the clinical phases start with testing for safety in a few human subjects, then expand to many study participants (potentially tens of thousands) to determine if the treatment is effective. Genetic testing is common, particularly when there is evidence of variation in metabolic rate. The purpose of clinical trials is to find ways to more effectively prevent, diagnose, or treat disease. Pilot studies and feasibility studies are small versions of studies which are sometimes done before a large trial takes place. [3] Phase 0 trials are also known as human microdosing studies and are designed to speed up the development of promising drugs or imaging agents by establishing very early on whether the drug or agent behaves in human subjects as was expected from preclinical studies. There is a history of clinical research done on glycosaminoglycans, especially glucosamine and chondroitin, for the treatment of arthritis. Clinical trials were first introduced in Avicennas The ...

Papillomaviruses (PVs) infect epithelial cells and are the main causative agent of cervical carcinoma. There are today more than a hundred different PV types and these can be divided into high risk and low risk types. They infect differentiating epithelial cells which make it cumbersome to propagate and produce human papillomavirus (HPV) virions. A common method to study HPV infection is to use HPV virus like particles (VLPs) produced in recombinant eukaryotic expression systems. Glycosaminoglycans (GAGs) have been described as an initial attachment receptor for several viruses. Our aim was to study the interactions between HPV VLPs and different GAGs to determine how these could affect binding and internalization. We found that soluble heparin was the best GAG inhibitor of HPV-16 VLP binding followed by heparan sulfate of mucosal origin. We could also see that CHO cells deficient in GAG expression had a reduced ability to bind VLPs, as did cells pretreated with heparinase III. Our results ...

Proteoglycans (PGs) modulate numerous signaling pathways during development through binding of their glycosaminoglycan (GAG) side chains to various signaling molecules, including fibroblast growth factors (FGFs). A majority of PGs possess two or more GAG side chains, suggesting that GAG multivalency is imperative for biological functions in vivo. However, only a few studies have examined the biological significance of GAG multivalency. In this report, we utilized a library of bis- and tris-xylosides that produce two and three GAG chains on the same scaffold, respectively, thus mimicking PGs, to examine the importance of GAG valency and chain type in regulating FGF/FGFR interactions in vivo in zebrafish. A number of bis- and tris-xylosides, but not mono-xylosides, caused an elongation phenotype upon their injection into embryos. In situ hybridization showed that elongated embryos have elevated expression of the FGF target gene mkp3 but unchanged expression of reporters for other pathways, ...

Podocytes synthesize the majority of the glomerular basement membrane components with some contribution from the glomerular capillary endothelial cells. The anionic charge of heparan sulfate proteoglycans is conferred by covalently attached heparan sulfate glycosaminoglycans and these are thought to provide critical charge selectivity to the glomerular basement membrane for ultrafiltration. One key component in herparan sulfate glycosaminoglycan assembly is the Ext1 gene product encoding a subunit of heparan sulfate co-polymerase. Here we knocked out Ext1 gene expression in podocytes halting polymerization of heparin sulfate glycosaminoglycans on the proteoglycan core proteins secreted by podocytes. Glomerular development occurred normally in these knockout animals but changes in podocyte morphology, such as foot process effacement, were seen as early as 1 month after birth. Immunohistochemical analysis showed a significant decrease in heparan sulfate glycosaminoglycans confirmed by ...

N2 - Glycosaminoglycans in urine from patients representing the major different mucopolysaccharidoses were separated and measured by use of a procedure that requires only 2 mL of urine. The compounds were resolved by two-dimensional electrophoresis on cellulose acetate plates and made visible by staining with Alcian Blue. They were identified by co-migration with standard glycosaminoglycans, by digestion with specific glycosidases, and by specific degradation with HNO 2. They were quantitated by comparing the absorbance of eluates of the stained spots to appropriate standard curves for each glycosaminoglycan. This study revealed additional findings. About half of the patients excreted small amounts of heparin. Further, the keratan sulfate in samples from ...

Keratan sulfate (KS) is a glycosaminoglycan with the basic disaccharide unit of N-acetyllactosamine, Gal(b1-4)GlcNAc(b1-3), with sulfate esters at C-6 of GlcNAc and Gal residues.

Integration of gene delivery vectors with a biomaterial scaffold offers the potential to bypass the use of expensive and relatively inefficient growth factor supplementation strategies to augment cell behavior. However, integration of cationic polymer based gene delivery vectors within three-dimensional biomaterials, particularly matrices which can carry significant surface charge, remains poorly explored. We examined the potential of polyethylenimine (PEI) as a gene delivery vector for three-dimensional ...

ARIA, or acetylcholine receptor-inducing activity, is a polypeptide that stimulates the synthesis of acetylcholine receptors in skeletal muscle. Here we demonstrate that the ability of ARIA to induce phosphorylation of its receptor in muscle is blocked by highly charged glycosaminoglycans. ARIA constructs lacking the NH2-terminal portion, containing an immunoglobulin-like domain, are fully active and are not inhibited by glycosaminoglycans. Limited proteolysis of ARIA with subtilisin blocks the glycosaminoglycan interaction by degrading this NH2-terminal portion, but preserves the active, EGF-like domain. We also show that ARIA can be released from freshly dissociated cells from embryonic chick spinal cord and cerebellum by either heparin, high salt or limited proteolysis with subtilisin, suggesting that ARIA is bound to the extracellular matrix through charged interactions. We present a model of how ARIA may be stored in extracellular matrix at developing synapses and how its release may be ...

Glycosaminoglycans (GAGs) play a central role in embryonic development by regulating the movement and signaling of morphogens. We have previously demonstrated that GAGs are the co-receptors for Fgf10 signaling in the lacrimal gland epithelium, but their function in the Fgf10-producing periocular mesenchyme is still poorly understood. In this study, we have generated a mesenchymal ablation of UDP-glucose dehydrogenase (Ugdh), an essential biosynthetic enzyme for GAGs. Although Fgf10 RNA is expressed normally in the periocular mesenchyme, Ugdh mutation leads to excessive dispersion of Fgf10 protein, which fails to elicit an FGF signaling response or budding morphogenesis in the presumptive lacrimal gland epithelium. This is supported by genetic rescue experiments in which the Ugdh lacrimal gland defect is ameliorated by constitutive Ras activation in the epithelium but not in the mesenchyme. We further show that lacrimal gland development requires the mesenchymal expression of the heparan sulfate ...

A study by Martin et al was performed to test the hydrodynamic conditions obtained from different bioreactor conditions for cartilage tissues after sitting in culture for six weeks. They were able to test two different conditions to test for the production of glycosaminoglycan (GAG) [1]. The initial control was a static culture construct. In the first illustration, it is evident that GAG was able to be produced in the outer regions but do appear in the central regions of the tissue [1]. The first test was to use the spinner flasks for the tissue culture. In this culture it is evident that the media mixing allows for better production of GAG through the central areas of the tissue. It is clear that there is a more level distribution of the GAG production in the cartilage tissue cells. The second test was the implementation of a RWV bioreactor. In this test, it is evident that the lack of shear stress and better mixing at equilibrium generated a much more intense GAG concentration throughout the ...

Previous studies have indicated that CD44 isoforms, spliced with variant exons, are heterogeneously glycanated with chondroitin sulphate and heparan sulphate chains. Because such alternative splicing may regulate divergent biological effects of the specific isoforms, we analysed the consequences of this process on the composition and structure of the chondroitin-sulphate chains. Recombinant chimaeras were engineered with and without exons V3-10 or V3,8-10 and expressed as Ig fusion proteins in COS cells. In addition, the chondroitin sulphates of wild-type isoforms were contrasted with those of isoforms mutated with serine-to-alanine codon substitutions at a putative Ser-Gly-Ser-Gly glycosaminoglycan acceptor site within exon V3. The chondroitin sulphates contained both 4- and 6-sulphated galactosamine residues, although there was a high content of non-sulphated galactosamine-containing repeat units. Splicing of exons V4-7, which contain no Ser-Gly consensus motifs, resulted in increased ...

The proliferation response of stage 36 chick atrioventricular valve mesenchymal cells to fibroblast growth factor-2 (FGF-2) was studied in the tissue-like environment of three-dimensional cell aggregates maintained in organ culture. The mitogenic effects of FGF-2 on mesenchymal tissue depended on the FGF-2-stimulated formation of a fibronectin-containing extracellular matrix. The matrix was absent in unstimulated aggregates, and co-localized with regions of actively proliferating cells in stimulated aggregates. Inhibition of fibronectin matrix formation by the inclusion of Arg-Gly-Asp-containing peptides, which compete with fibronectin for binding to the cell surface alpha 5 beta 1 integrin receptors, abolished the proliferation effects of FGF-2. Inhibition of sulfation of cell surface glycosaminoglycans by treatment with sodium chlorate significantly reduced both the formation of the fibronectin matrix and cell proliferation in response to FGF-2, suggesting an involvement of the low-affinity ...

Young (60-80 days) mice of the low β-glucuronidase strain, C3H/HeJ, showed no differences in hepatic levels of glycosaminoglycans (GAGs) when compared to the randombred,

We are attempting to develop methods for the sequencing of glycosaminoglycans from their reducing end. Here we describe a procedure for the analysis of dermatan sulphate from pig skin. The glycosaminoglycan is released from its parent proteoglycan by exhaustive proteolysis by using both endo- and exo-peptidases. The amino group of the residual serine residue is conjugated with a p-hydroxyphenyl group, which in turn is iodinated with 125I (the Bolton-Hunter reagent, BHR). The ion-exchange-purified end-labelled dermatan sulphate is then degraded partially or completely by various enzymic or chemical means to yield fragments extending from the labelled serine residue to the point of cleavage. The various products are separated by gradient PAGE, detected by autoradiography and quantified by videodensitometry. Complete digestion with chondroitin ABC lyase affords the labelled fragment delta HexA-GalNAc(-SO4)-GlcA-Gal-Gal-Xyl-Ser(-BHR). The structure was confirmed by sequential degradation from the ...

TY - JOUR. T1 - Immunological characterization of human vitronectin and its binding to glycosaminoglycans. AU - Akama, Takao. AU - Yamada, Kenneth M.. AU - Seno, Nobuko. AU - Kashiwagi, Heihachira. AU - Funaki, Tomoyuki. AU - Hayashi, Masao. PY - 1986/10. Y1 - 1986/10. N2 - The cell-adhesive glycoprotein vitronectin in human plasma was characterized with a monospecific anti-vitronectin antibody. Vitronectin, a mixture of monomeric 75 and 65 kDa polypeptides, was found to have different ratios of amounts of 75 and 65 kDa polypeptides in immunoblots of sera from various healthy human donors. Two states of vitronectin were previously reported; the open state binds to heparin, but the cryptic state does not (Hayashi et al. (1985) J. Biochem. 98, 1135-1138). The anti-vitronectin antibody was suggested to react more strongly wth the open state of vitronectin than with the cryptic state. To quantitate all vitronectin regardless of its state, an enzyme-linked immunosorbent assay of vitronectin was ...

THESIS 8757 Tissue engineering (or regenerative medicine) is defined as the application of scientific principles to the synthesis of living tissues using bioreactors, cells, scaffolds, growth factors, or a combination (Rose and Oreffo, 2002). One of the principal methods in tissue engineering involves the use of a porous scaffold to support and guide synthesis of a 3D tissue or organ (Sachlos and Czernuszka, 2003). Collagen-Glycosaminoglycan scaffolds have found success in several clinical applications of tissue engineering (Yannas et al., 1989, Chamberlain et al., 1998). ...

The intrinsically disordered protein α-synuclein (aSN) is, in its fibrillated state, the main component of Lewy bodies—hallmarks of Parkinson’s disease. Additional Lewy body components include glycosaminoglycans, including heparan sulfate proteoglycans. In humans, heparan sulfate has, in an age-dependent manner, shown increased levels of sulfation. Heparin, a highly sulfated glycosaminoglycan, is a relevant mimic for mature heparan sulfate and has been shown to influence aSN fibrillation. Here, we decompose the underlying properties of the interaction between heparin and aSN and the effect of heparin on fibrillation. Via the isolation of the first 61 residues of aSN, which lacked intrinsic fibrillation propensity, fibrillation could be induced by heparin, and access to the initial steps in fibrillation was possible. Here, structural changes with shifts from disorder via type I β-turns to β-sheets were revealed, correlating with an increase in the aSN1–61/heparin molar

In addition to stimulating the production of collagen and elastin, copper peptides promote the production of glycosaminoglycans like hyaluronic acid. Glycosaminoglycans are found in the connective tissue and fluids in the human body and are largely responsible for keeping skin plump, supple and in the case of hyaluronic acid, hydrated. Whether or not copper peptides are safe has been debated, but since these compounds occur naturally, experts suggest that if you experience any irritation after using a product containing copper peptides, then you are more than likely sensitive to something else in the ingredient list. Further, clinical research has proven that copper peptides are antioxidants that fight against free radical damage, which is another major contributing factor to aging.. Using a product that contains copper peptides is a great way to fight against the signs of aging like fine lines and wrinkles. These naturally occurring compounds boost collagen and elastin production and stimulate ...

Glycosaminoglycans (GAGs) are intensely sulfated polysaccharides, ubiquitous in numerous tissues, epithelial surfaces and in the extracellular matrix, where they modulate all cell biology that involves signaling proteins, including cell differentiation, cell proliferation and angiogenesis. They are implicated in tumor suppression, inflammation, amyloidosis, inhibition of metastasis, and fertilization. While all of these are known to involve protein binding, structure-function relationships for GAGs are unknown. This is because structural analysis is confounded by the infinite heterogeneity of GAGs. The question of the biofunctionality of GAG heterogeneity has led to both denial and fascination, as GAG saccharide sequences appear to be random, but subject to genetic control.. Analytical chemistry has a central role to play in this mystery, but this 公案 (ko-an: paradox) demands - both as essential, new paradigms and new methods.. ...

While the initial work on identifying the importance of the ground regulatory system was done in Germany, more recent work examining the implications of inter and intra-cellular communication via the extra-cellular matrix has taken place in the U.S. and elsewhere. Structural continuity between extracellular, cyst skeletal and nuclear components was discussed by Hay,[15] Berezny et al.[16] and Oschman.[17] Historically, these elements have been referred to as ground substances, and because of their continuity, they act to form a complex, interlaced system that reaches into and contacts every part of the body. Even as early as 1851 it was recognized that the nerve and blood systems do not directly connect to the cell, but are mediated by and through an extracellular matrix.[18]. Recent research regarding the electrical charges of the various glycol-protein components of the extracellular matrix shows that because of the high density of negative charges on glycosaminoglycans (provided by sulfate ...

There is extensive evidence that the structurally complex, negatively charged GAG side chains of HSPGs are crucial for signaling by diverse secreted ligands, including BMPs. Although the distribution of HSPGs is generally assumed to be ubiquitous, our data showing that GAGs are absent in the first three hours after egg laying but are rapidly synthesized thereafter demonstrates that HSPG expression can, in fact, be precisely temporally regulated. We have shown that this regulation results from an absence of enzymes essential for HSPG synthesis, owing to a block to their translation. Furthermore, our data strongly support the notion that the translational control mechanism involves the use of developmentally regulated internal ribosome entry sites (IRESs) in mRNA 5′ UTRs. Translationally blocking GAG synthesis may enable generation of the Dpp/Scw activity gradient in the absence of GAGs, while permitting rapid GAG synthesis from the abundant maternal mRNA supply coincident with the expression of ...

The prevalence of type 2 diabetes is expected to double by 2030. Kidney disease cases are sure to rise in parallel.. What was hoped to be a promising new drug to protect the kidneys has failed to benefit diabetes patients with kidney disease, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). The results call into question the usefulness of the drug sulodexide.. Kidney disease due to diabetes is the most common cause of kidney failure in developed countries. The number of patients with type 2 diabetes is expected to double and reach 366 million individuals worldwide by 2030. Kidney disease cases are sure to rise in parallel.. Investigators have wondered whether sulodexide, which belongs to a class of drugs called glycosaminoglycans, may protect the kidneys. The drug is actually a naturally occurring compound and has been used for more than 20 years to treat various heart conditions. Previous research indicates that sulodexide reduces ...

Chemokines are peptide ligands that activate G protein-coupled receptors and that bind glycosaminoglycans (GAGs) on the cell surface. Through these two interactions, chemokines participate in leukocyte migration and inflammatory signaling. Although studies of crystals and solution structures indicate that chemokines are dimers, various experiments with monomeric interleukin 8 (IL-8) suggest that the monomer may activate its GPCR, CXCR1. Fernando et al. provide in vitro evidence from isothermal titration calorimetry (ITC) and sedimentation equilibrium studies that IL-8 interacts with the N-terminal domain of CXCR1 (site 1) as a monomer. Sedimentation equilibration experiments showed a 1:1 stoichiometry and suggested that the dimeric IL-8 in solution must dissociate to bind the receptor peptide. ITC experiments supported the conclusion that the ligand dimer dissociated and then IL-8 bound to the receptor as a monomer. The authors propose that the dimeric IL-8 serves as a negative regulator for ...

Dynamic covalent chemistry (DCC) is currently exploited in several areas of biomedical applications such as in drug discovery, sensing, molecular separation, catalysis etc. Hydrazone and oxime chemistry have several advantages, such as mild reaction conditions, selectivity, efficiency, and biocompatibility and therefore, have the potential to be for bioconjugation applications. However, these reactions suffer from major drawbacks of slow reaction rate and poor bond stability under physiological conditions. In this regard, the work presented in this thesis focuses on designing novel bioconjugation reactions amenable under physiological conditions with tunable reaction kinetics and conjugation stability.. The first part of the thesis presents different strategies of dynamic covalent reactions utilized for biomedical applications. In the next part, a detailed study related to the mechanism and catalysis of oxime chemistry was investigated in the presence of various catalysts. Aniline, carboxylate ...
