Abstract
Chondroitin sulfate (CS), dermatan sulfate (DS), and CS/DS hybrid chains are natural complex glycosaminoglycans with high structural diversity and widely distributed in marine organisms, such as fish, shrimp, starfish, and sea cucumber. Numerous CS, DS, and CS/DS hybrid chains with various structures and activities have been obtained from marine animals and have received extensive attention. However, only a few of these hybrid chains have been well-characterized and commercially developed. This review presents information on the extraction, purification, structural characterization, biological activities, potential action mechanisms, and structure-activity relationships of marine CS, DS, and CS/DS hybrid chains. We also discuss the challenges and perspectives in the research of CS, DS, and CS/DS hybrid chains. This review may provide a useful reference for the further investigation, development, and application of CS, DS, and CS/DS hybrid chains in the fields of functional foods and therapeutic agents.

Abstract
Fibrillar collagens and glycosaminoglycans (GAGs) are structural biomolecules that are natively abundant to the extracellular matrix (ECM). Prior studies have quantified the effects of GAGs on the bulk mechanical properties of the ECM. However, there remains a lack of experimental studies on how GAGs alter other biophysical properties of the ECM, including ones that operate at the length scales of individual cells such as mass transport efficiency and matrix microstructure. This study focuses on the GAG molecules chondroitin sulfate (CS), dermatan sulfate (DS), and hyaluronic acid (HA). CS and DS are stereoisomers while HA is the only non-sulfated GAG. We characterized and decoupled the effects of these GAG molecules on the stiffness, transport, and matrix microarchitecture properties of type I collagen hydrogels using mechanical indentation testing, microfluidics, and confocal reflectance imaging, respectively. We complement these biophysical measurements with turbidity assays to profile collagen aggregate formation. Surprisingly, only HA enhanced the ECM indentation modulus, while all three GAGs had no effect on hydraulic permeability. Strikingly, we show that CS, DS, and HA differentially regulate the matrix microarchitecture of hydrogels due to their alterations to the kinetics of collagen self-assembly. In addition to providing information on how GAGs define key physical properties of the ECM, this work shows new ways in which stiffness measurements, microfluidics, microscopy, and turbidity kinetics can be used complementarily to reveal details of collagen self-assembly and structure. STATEMENT OF SIGNIFICANCE: Collagen and glycosaminoglycans (GAGs) are integral to the structure, function, and bioactivity of the extracellular matrix (ECM). Despite widespread interest in collagen-GAG composite hydrogels, there is a lack of quantitative understanding of how different GAGs alter the biophysical properties of the ECM across tissue, cellular, and subcellular length scales. Here we show using mechanical, microfluidic, microscopy, and analytical methods and measurements that the GAG molecules chondroitin sulfate, dermatan sulfate, and hyaluronic acid differentially regulate the mechanical, transport, and microstructural properties of hydrogels due to their alterations to the kinetics of collagen self-assembly. As such, these results will inform improved design and utilization of collagen-based scaffolds of tailored composition, mechanical properties, molecular availability due to mass transport, and microarchitecture.

Abstract
Glycosaminoglycans (GAGs) with unique structures from marine animals show intriguing pharmacological activities and negligible biological risks, providing more options for us to explore safer agents. The swim bladder is a tonic food and folk medicine, and its GAGs show good anticoagulant activity. In this study, two GAGs, CMG-1.0 and GMG-1.0, were extracted and isolated from the swim bladder of Cynoscion microlepidotus and Gadus morhua. The physicochemical properties, precise structural characteristics, and anticoagulant activities of these GAGs were determined for the first time. The analysis results of the CMG-1.0 and GMG-1.0 showed that they were chondroitin sulfate (CS)/dermatan sulfate (DS) hybrid chains with molecular weights of 109.3 kDa and 123.1 kDa, respectively. They were mainly composed of the repeating disaccharide unit of -{IdoA-α1,3-GalNAc4S-β1,4-}- (DS-A). The DS-B disaccharide unit of -{IdoA2S-α1,3-GalNAc4S-β1,4-}- also existed in both CMG-1.0 and GMG-1.0. CMG-1.0 had a higher proportion of CS-O disaccharide unit -{-GlcA-β1,3-GalNAc-β1,4-}- but a lower proportion of CS-E disaccharide unit -{-GlcA-β1,3-GalNAc4S6S-β1,4-}- than GMG-1.0. The disaccharide compositions of the GAGs varied in a species-specific manner. Anticoagulant activity assay revealed that both CMG-1.0 and GMG-1.0 had potent anticoagulant activity, which can significantly prolong activated partial thromboplastin time. GMG-1.0 also can prolong the thrombin time. CMG-1.0 showed no intrinsic tenase inhibition activity, while GMG-1.0 can obviously inhibit intrinsic tenase with EC50 of 58 nM. Their significantly different anticoagulant activities may be due to their different disaccharide structural units and proportions. These findings suggested that swim bladder by-products of fish processing of these two marine organisms may be used as a source of anticoagulants.

Abstract
(1) Background: In this study, we evaluated the modulation of urine glycosaminoglycans (GAGs), which resulted from etanercept (ETA) therapy in patients with juvenile idiopathic arthritis (JIA) in whom methotrexate therapy failed to improve their clinical condition. (2) Methods: The sulfated GAGs (sGAGs, by complexation with blue 1,9-dimethylmethylene), including chondroitin-dermatan sulfate (CS/DS) and heparan sulfate (HS), as well as non-sulfated hyaluronic acid (HA, using the immunoenzymatic method), were determined in the blood of 89 children, i.e., 30 healthy children and 59 patients with JIA both before and during two years of ETA treatment. (3) Results: We confirmed the remodeling of the urinary glycan profile of JIA patients. The decrease in the excretion of sGAGs (p < 0.05), resulting from a decrease in the concentration of the dominant fraction in the urine, i.e., CS/DS (p < 0.05), not compensated by an increase in the concentration of HS (p < 0.000005) and HA (p < 0.0005) in the urine of patients with the active disease, was found. The applied biological therapy, leading to clinical improvement in patients, at the same time, did not contribute to normalization of the concentration of sGAGs (p < 0.01) in the urine of patients, as well as CS/DS (p < 0.05) in the urine of sick girls, while it promoted equalization of HS and HA concentrations. These results indicate an inhibition of the destruction of connective tissue structures but do not indicate their complete regeneration. (4) Conclusions: The metabolisms of glycans during JIA, reflected in their urine profile, depend on the patient's sex and the severity of the inflammatory process. The remodeling pattern of urinary glycans observed in patients with JIA indicates the different roles of individual types of GAGs in the pathogenesis of osteoarticular disorders in sick children. Furthermore, the lack of normalization of urinary GAG levels in treated patients suggests the need for continued therapy and continuous monitoring of its effectiveness, which will contribute to the complete regeneration of the ECM components of the connective tissue and thus protect the patient against possible disability.

Abstract
OBJECTIVE Danaparoid sodium is a biopolymeric complex drug composed of the most abundant heparan sulfate (HS) followed in descending order by dermatan sulfate (DS) and chondroitin sulfate (CS). This composite nature explains its peculiar antithrombotic and anticoagulant properties and make it particularly advantageous when the risk of heparin-induced thrombocytopenia occurs. A specific control of the danaparoid composition is required by the Ph. Eur. The monograph includes the CS and DS limit contents and describes the method for their quantification through selective enzymatic degradations. MATERIALS AND METHODS In this study, a quantitative two-dimensional nuclear magnetic resonance (NMR) method is proposed as a new method suitable for CS and DS quantification. Statistical comparison of the results provided by the analysis of a series of danaparoid samples with both NMR and enzymatic methods highlights a small systematic difference, likely derived from lyase-resistant sequences bearing oxidized terminals. Some modified structures, whose survival to the enzymatic action was confirmed by mass spectrometry, can be detected and quantified by NMR. CONCLUSION AND RESULTS The proposed NMR method can serve for the determination of DS and CS contents, is an easy-to-apply method with no dependence from enzymes and standards, and provides extensive structural information on the overall glycosaminoglycans mixture.

Abstract
Neurodegeneration is caused by the progressive loss of the structure and function of neurons, leading to cell death, and it is the main cause of many neurodegenerative diseases. Many molecules, such as glycosaminoglycans (GAGs), have been studied for their potential to prevent or treat these diseases. They are widespread in nature and perform an important role in neuritogenesis and neuroprotection. Here we investigated the neuritogenic and neuroprotective role of Phallusia nigra dermatan sulfate (PnD2,6S) and compared it with two distinct structures of chondroitin sulfate (C6S) and dermatan sulfate (D4S). For this study, a neuro 2A murine neuroblastoma cell line was used, and a chemical lesion was induced by the pesticide rotenone (ROT). We observed that PnD2,6S + ROT had a better neuritogenic effect than either C6S + ROT or D4S + ROT at a lower concentration (0.05 μg/mL). When evaluating the mitochondrial membrane potential, PnD2,6S showed a neuroprotective effect at a concentration of 0.4 μg/mL. These data indicate different mechanisms underlying this neuronal potential, in which the sulfation pattern is important for neuritogenic activity, while for neuroprotection all DS/CS structures had similar effects. This finding leads to a better understanding the chemical structures of PnD2,6S, C6S, and D4S and their therapeutic potential.

Abstract
Crude anionic polysaccharides extracted from the Pacific starfish Lethasterias fusca were purified by anion-exchange chromatography. The main fraction LF, having MW 14.5 kDa and dispersity 1.28 (data of gel-permeation chromatography), was solvolytically desulfated and giving rise to preparation LF-deS with a structure of dermatan core [→3)-β-d-GalNAc-(1→4)-α-l-IdoA-(1→]n, which was identified according to NMR spectroscopy data. Analysis of the NMR spectra of the parent fraction LF led to identification of the main component as dermatan sulfate LF-Derm →3)-β-d-GalNAc4R-(1→4)-α-l-IdoA2R3S-(1→ (where R was SO3 or H), bearing sulfate groups at O-3 or both at O-2 and O-3 of α-l-iduronic acid, as well as at O-4 of some N-acetyl-d-galactosamine residues. The minor signals in NMR spectra of LF were assigned as resonances of heparinoid LF-Hep composed of the fragments →4)-α-d-GlcNS3S6S-(1→4)-α-l-IdoA2S3S-(1→. The 3-O-sulfated and 2,3-di-O-sulfated iduronic acid residues are very unusual for natural glycosaminoglycans, and further studies are needed to elucidate their possible specific influence on the biological activity of the corresponding polysaccharides. To confirm the presence of these units in LF-Derm and LF-Hep, a series of variously sulfated model 3-aminopropyl iduronosides were synthesized and their NMR spectra were compared with those of the polysaccharides. Preparations LF and LF-deS were studied as stimulators of hematopoiesis in vitro. Surprisingly, it was found that both preparations were active in these tests, and hence, the high level of sulfation is not necessary for hematopoiesis stimulation in this particular case.

Abstract
Biglycan (BGN), a small leucine-rich repeat proteoglycan, is involved in a variety of pathological processes including malignant transformation, for which the upregulation of BGN was found related to cancer cell invasiveness. Because the functions of BGN are mediated by its chondroitin/dermatan sulfate (CS/DS) chains through the sulfates, the determination of CS/DS structure and sulfation pattern is of major importance. In this study, we have implemented an advanced glycomics method based on ion mobility separation (IMS) mass spectrometry (MS) and tandem MS (MS/MS) to characterize the CS disaccharide domains in BGN. The high separation efficiency and sensitivity of this technique allowed the discrimination of five distinct CS disaccharide motifs, of which four irregulated in their sulfation pattern. For the first time, trisulfated unsaturated and bisulfated saturated disaccharides were found in BGN, the latter species documenting the non-reducing end of the chains. The structural investigation by IMS MS/MS disclosed that in one or both of the CS/DS chains, the non-reducing end is 3-O-sulfated GlcA in a rather rare bisulfated motif having the structure 3-O-sulfated GlcA-4-O-sulfated GalNAc. Considering the role played by BGN in cancer cell spreading, the influence on this process of the newly identified sequences will be investigated in the future.

Abstract
Glycosaminoglycans (GAGs) are a class of linear anionic periodic polysaccharides containing disaccharide repetitive units. These molecules interact with a variety of proteins in the extracellular matrix and so participate in biochemically crucial processes such as cell signalling affecting tissue regeneration as well as the onset of cancer, Alzheimer's or Parkinson's diseases. Due to their flexibility, periodicity and chemical heterogeneity, often termed "sulfation code", GAGs are challenging molecules both for experiments and computation. One of the key questions in the GAG research is the specificity of their intermolecular interactions. In this study, we make a step forward to deciphering the "sulfation code" of chondroitin sulfates-4,6 (CS4, CS6, where the numbers correspond to the position of sulfation in NAcGal residue) and dermatan sulfate (DS), which is different from CSs by the presence of IdoA acid instead of GlcA. We rigorously investigate two sets of these GAGs in dimeric, tetrameric and hexameric forms with molecular dynamics-based descriptors. Our data clearly suggest that CS4, CS6 and DS are substantially different in terms of their structural, conformational and dynamic properties, which contributes to the understanding of how these molecules can be different when they bind proteins, which could have practical implications for the GAG-based drug design strategies in the regenerative medicine.

Abstract
Glycosaminoglycans are highly anionic functional polysaccharides with information content in their structure that plays a major role in the communication between the cell and the extracellular environment. The study presented here reports the label-free detection and analysis of glycosaminoglycan molecules at the single molecule level using sensing by biological nanopore, thus addressing the need to decipher structural information in oligo- and polysaccharide sequences, which remains a major challenge for glycoscience. We demonstrate that a wild-type aerolysin nanopore can detect and characterize glycosaminoglycan oligosaccharides with various sulfate patterns, osidic bonds and epimers of uronic acid residues. Size discrimination of tetra- to icosasaccharides from heparin, chondroitin sulfate and dermatan sulfate was investigated and we show that different contents and distributions of sulfate groups can be detected. Remarkably, differences in α/β anomerization and 1,4/1,3 osidic linkages can also be detected in heparosan and hyaluronic acid, as well as the subtle difference between the glucuronic/iduronic epimers in chondroitin and dermatan sulfate. Although, at this stage, discrimination of each of the constituent units of GAGs is not yet achieved at the single-molecule level, the resolution reached in this study is an essential step toward this ultimate goal.

Abstract
Proteoglycans are heavily glycosylated proteins, covalently linked to one or more glycosaminoglycan (GAG) chains, abundantly expressed in the extracellular matrix (ECM). Among GAGs, chondroitin sulfate (CS) and dermatan sulfate (DS) play an essential role at the ECM level; however, the composition of the hybrid CS/DS as well as the distribution of the sulfate groups along the chain were also shown to influence biological activities in brain. The elevated structural diversity of CS/DS motifs, in which sulfation may occur at GalNAc and/or IdoA/GlcA in various combinations, requires the development of specific high performance analytical methods for reliable elucidation. Due to its sensitivity, reproducibility, and efficiency, capillary zone electrophoresis (CZE) for separation of CS/DS oligosaccharides coupled to electrospray ionization mass spectrometry (ESI-MS) for their structure determination contributed an essential progress to this field.In the present chapter, two powerful methods based on CZE for separation and ESI-MS for identification and structural analysis of CS/DS are presented. The first part is devoted to offline CZE-ESI-MS based on fraction collection, screening by negative ion mode nanoESI, and fragmentation analysis in tandem MS using collision-induced dissociation (CID) at low ion acceleration energies. In the second part of the chapter, a strategy for online CZE-ESI-MS in normal polarity and negative mode ESI followed by tandem MS in real-time data-dependent acquisition mode for CS/DS separation, screening, and fragmentation is described in detail. The latter method entails the in-laboratory manufacturing of a simple yet sturdy interface for the online CZE coupling to ESI-MS and the optimization of the coupled system for total analysis of regularly sulfated and irregularly, i.e., under- and oversulfated CS/DS domains.

Abstract
Glycomics represents one of the last frontiers and most challenging in omic analysis. Glycosylation occurs in the endoplasmic reticulum and the Golgi organelle and its control is neither well-understood nor predictable based on proteomic or genomic analysis. One of the most structurally complex classes of glycoconjugates is the proteoglycans (PGs) and their glycosaminoglycan (GAG) side chains. Previously, our laboratory solved the structure of the chondroitin sulfate chain of the bikunin PG. The current study examines the much more complex structure of the dermatan sulfate GAG chain of decorin PG. By utilizing sophisticated separation methods followed by compositional analysis, domain mapping, and tandem mass spectrometry coupled with analysis by a modified genetic algorithm approach, the structural motif for the decorin dermatan sulfate chain was determined. This represents the second example of a GAG with a prominent structural motif, suggesting that the structural variability of this class of glycoconjugates is somewhat simpler than had been expected.

Abstract
Programmed cell death protein-1 (PD-1) is a prominent immune checkpoint receptor interacting with its ligand, programmed cell death protein ligand-1 (PD-L1, B7-H1). The PD-1/PD-L1 interaction induces functional exhaustion of tumor-reactive cytotoxic T cells and, thus, interferes with antitumor T-cell immunity. In addition, PD-1/PD-L1 interaction promotes tumorigenesis via the mTOR signaling pathway in a group of cancers including melanoma. Based on the dual functions of PD-1/PD-L1 interactions in tumor progression, we hypothesize that siRNA targeting PD-L1 (siPD-L1) will suppress melanoma growth, acting on both immune checkpoint and intrinsic tumorigenesis pathways. We tested this hypothesis by delivering siPD-L1 with a polymeric carrier ("pd") consisting of disulfide-cross-linked polyethylenimine (CLPEI) and dermatan sulfate (DS), which we previously found to have a specific interaction with CD146-positive B16F10 melanoma cells. The siPD-L1/pd suppressed the expression of PD-L1 in the interferon-γ (IFN-γ)-challenged B16F10 melanoma cells in a cell-type dependent manner and attenuated the expression of tumor-specific genes in B16F10 cells. siPD-L1/pd suppressed the B16F10 melanoma growth in C57BL/6 immune-competent mice with increased tumor-specific immunity. siPD-L1/pd also suppressed melanoma growth in immune-compromised nude mice. Both animals showed a positive correlation between PD-L1 and p-S6k (a marker of mTOR pathway activation) expression in tumors. These results indicate that the siPD-L1/pd complex attenuates melanoma growth in both T-cell-dependent and independent mechanisms.

Abstract
Danaparoid sodium salt, is the active component of ORGARAN, an anticoagulant and antithrombotic drug constituted of three glycosaminoglycans (GAGs) obtained from porcine intestinal mucosa extracts. Heparan sulfate is the major component, dermatan sulfate and chondroitin sulfate being the minor ones. Currently dermatan sulfate and chondroitin sulfate are quantified by UV detection of their unsaturated disaccharides obtained by enzymatic depolymerization. Due to the complexity of danaparoid biopolymers and the presence of shared components, an orthogonal approach has been applied using more advanced tools and methods. To integrate the analytical profile, 2D heteronuclear single quantum coherence (HSQC) NMR spectroscopy was applied and found effective to identify and quantify GAG component signals as well as those of some process signatures of danaparoid active pharmaceutical ingredient (API) batches. Analyses of components of both API samples and size separated fractions proceeded through the determination and distribution of the molecular weight (Mw) by high performance size exclusion chromatographic triple detector array (HP-SEC-TDA), chain mapping by LC/MS, and mono- (1H and 13C) and bi-dimensional (HSQC) NMR spectroscopy. Finally, large scale chromatographic isolation and depolymerization of each GAG followed by LC/MS and 2D-NMR analysis, allowed the sequences to be defined and components to be evaluated of each GAG including oxidized residues of hexosamines and uronic acids at the reducing ends.

Abstract
Glycosaminoglycans (GAGs) are linear negatively charged polysaccharides and important components of extracellular matrices and cell surface glycan layers such as the endothelial glycocalyx. The GAG family includes sulfated heparin, heparan sulfate (HS), dermatan sulfate (DS), chondroitin sulfate (CS), keratan sulfate, and non-sulfated hyaluronan. Because relative expression of GAGs is dependent on cell-type and niche, isolating GAGs from cell cultures and tissues may provide insight into cell- and tissue-specific GAG structure and functions. In our objective to obtain structural information about the GAGs expressed on a specialized mouse glomerular endothelial cell culture (mGEnC-1) we adapted a recently published GAG isolation protocol, based on cell lysis, proteinase K and DNase I digestion. Analysis of the GAGs contributing to the mGEnC-1 glycocalyx indicated a large HS and a minor CS content on barium acetate gel. However, isolated GAGs appeared resistant to enzymatic digestion by heparinases. We found that these GAG extracts were heavily contaminated with RNA, which co-migrated with HS in barium acetate gel electrophoresis and interfered with 1,9-dimethylmethylene blue (DMMB) assays, resulting in an overestimation of GAG yields. We hypothesized that RNA may be contaminating GAG extracts from other cell cultures and possibly tissue, and therefore investigated potential RNA contaminations in GAG extracts from two additional cell lines, human umbilical vein endothelial cells and retinal pigmental epithelial cells, and mouse kidney, liver, spleen and heart tissue. GAG extracts from all examined cell lines and tissues contained varying amounts of contaminating RNA, which interfered with GAG quantification using DMMB assays and characterization of GAGs by barium acetate gel electrophoresis. We therefore recommend routinely evaluating the RNA content of GAG extracts and propose a robust protocol for GAG isolation that includes an RNA digestion step.

Abstract
Sulfatases that specifically catalyze the hydrolysis of the sulfate groups on chondroitin sulfate (CS)/dermatan sulfate (DS) poly- and oligosaccharides belong to the formylglycine-dependent family of sulfatases and have been widely found in various mammalian and bacterial organisms. However, only a few types of CS/DS sulfatase have been identified so far. Recently, several novel CS/DS sulfatases have been cloned and characterized. Advanced studies have provided significant insight into the biological function and mechanism of action of CS/DS sulfatases. Moreover, further studies will provide powerful tools for structural and functional studies of CS/DS as well as related applications. This article reviews the recent progress in CS/DS sulfatase research and is expected to initiate further research in this field.

Abstract
Type XV is a large collagen-proteoglycan found in all human tissues examined. By light microscopy it was localized to most epithelial and all nerve, muscle, fat and endothelial basement membrane zones except for the glomerular capillaries or hepatic/splenic sinusoids. This widespread distribution suggested that type XV may be a discrete structural component that acts to adhere basement membrane to the underlying connective tissue. To address these issues, immunogold ultrastructural analysis of type XV collagen in human kidney, placenta, and colon was conducted. Surprisingly, type XV was found almost exclusively associated with the fibrillar collagen network in very close proximity to the basement membrane. Type XV exhibited a focal appearance directly on the surface of, or extending from, the fibers in a linear or clustered array. The most common single arrangement was a bridge of type XV gold particles linking thick-banded fibers. The function of type XV in this restricted microenvironment is expected to have an intrinsic dependence upon its modification with glycosaminoglycan chains. Present biochemical characterization showed that the type XV core protein in vivo carries chains of chondroitin/dermatan sulfate alone, or chondroitin/dermatan sulfate together with heparan sulfate in a differential ratio. Thus, type XV collagen may serve as a structural organizer to maintain a porous meshwork subjacent to the basement membrane, and in this domain may play a key role in signal transduction pathways.

Abstract
Microbial pathogens have evolved several strategies for interacting with host cell components, such as glycosaminoglycans (GAGs). Some microbial proteins involved in host-GAG binding have been described; however, a systematic study on microbial proteome-mammalian GAG interactions has not been conducted. Here, we used Escherichia coli proteome chips to probe four typical mammalian GAGs, heparin, heparan sulphate (HS), chondroitin sulphate B (CSB), and chondroitin sulphate C (CSC), and identified 185 heparin-, 62 HS-, 98 CSB-, and 101 CSC-interacting proteins. Bioinformatics analyses revealed the unique functions of heparin- and HS-specific interacting proteins in glycine, serine, and threonine metabolism. Among all the GAG-interacting proteins, three were outer membrane proteins (MbhA, YcbS, and YmgH). Invasion assays confirmed that mutant E. coli lacking ycbS could not invade the epithelial cells. Introducing plasmid carrying ycbS complemented the invading defects at ycbS lacking E. coli mutant, that can be further improved by overexpressing ycbS. Preblocking epithelial cells with YcbS reduced the percentage of E. coli invasions. Moreover, we observed that whole components of the ycb operon were crucial for invasion. The displacement assay revealed that YcbS binds to the laminin-binding site of heparin and might affect the host extracellular matrix structure by displacing heparin from laminin.

Abstract
Shark fin, used as a food, is a rich source of glycosaminoglyans (GAGs), acidic polysaccharides having important biological activities, suggesting their nutraceutical and pharmaceutical application. A comprehensive survey of GAGs derived from the fin was performed on 11 elasmobranchs, including several deep sea sharks. Chondroitin sulfate (CS) and hyaluronic acid (HA) were found in Isurus oxyrinchus, Prionace glauca, Scyliorhinus torazame, Deania calcea, Chlamydoselachus anguineus, Mitsukurina owatoni, Mustelus griseus and Dasyatis akajei, respectively. CS was only found from Chimaera phantasma, Dalatias licha, and Odontaspis ferox, respectively. Characteristic disaccharide units of most of the CS were comprised of C- and D-type units. Interestingly, substantial amount of CS/dermatan sulfate (DS) was found in the dried fin (without skin and cartilage) of Isurus oxyrinchus and Prionace glauca. 1H-NMR analysis showed that the composition of glucuronic acid (GlcA) and iduronic acid (IdoA) in shark CS/DS was 41.2% and 58.8% (Isurus oxyrinchus), 36.1% and 63.9% (Prionace glauca), respectively. Furthermore, a substantial proportion of this CS/DS consisted of E-, B- and D-type units. Shark CS/DS stimulated neurite outgrowth of hippocampal neurons at a similar level as DS derived from invertebrate species. Midkine and pleiotrophin interact strongly with CS/DS from Isurus oxyrinchus and Prionace glauca, affording Kd values of 1.07 nM, 6.25 nM and 1.70 nM, 1.88 nM, respectively. These results strongly suggest that the IdoA-rich domain of CS/DS is required for neurite outgrowth activity. A detailed examination of oligosaccharide residues, produced by chondroitinase ACII digestion, suggested that the IdoA and B-type units as well as A- and C-type units were found in clusters in shark CS/DS. In addition, it was discovered that the contents of B-type units in these IdoA-rich domain increased in a length dependent manner, while C- and D-type units were located particularly in the immediate vicinity of the IdoA-rich domain.

Abstract
In this work, a CE method with bare gold nanorods (GNRs) based pseudostationary phase was developed and applied for the separation of chondroitin sulfate (CS) isomers, CS, and dermatan sulfate (DS). The separation efficiency was investigated by varying the experimental parameters such as concentration and pH of the BGE, separation voltage, internal diameter of capillary, different size, and morphology of gold nanomaterials. Results showed that different size and morphology of gold nanomaterials had different effects on the separation of CS and DS. The best separation of CS and DS was achieved in the BGE composed of aqueous 150 mmol/L (mM) ethylenediamine + 20 mM sodium dihydrogen phosphate + 30% v/v GNRs, pH 4.5, at the separation voltage of -10 kV. Capillary was 59.2 cm in length (effective length 49 cm), 50 μm id capillary thermostated at 25°C. CE with bare GNRs used as pseudostationary phase was shown to be a suitable technique for the separation of CS and DS mixtures with wider peaks. RSD of migration time and peak area of CS and DS were 0.13, 0.14 and 0.86, 1.07%, respectively.

Abstract
Capillary electrophoresis is a separation technique with high resolving power and sensitivity with applications in glycosaminoglycan analysis. In this chapter, we present validated protocols for determining the variously sulfated chondroitin or dermatan sulfate-derived disaccharides. These approaches involve degradation of the polysaccharides with specific chondro/dermato-lyases and electrophoretic analysis with capillary zone electrophoresis in a low pH operating buffer and reversed polarity. This methodology has been applied to drug/nutraceutical formulations or to biologic samples (blood serum, lens capsule) and has been validated. Analysis of biologic tissue samples is often more demanding in terms of detection sensitivity, and thus concentration pretreatment steps and/or a derivatization step with 2-aminoacridone are often advisable.

Abstract
Aortic smooth muscle cells produce chondroitin/dermatan sulfate (CS/DS) proteoglycans that regulate extracellular matrix organization and cell behavior in normal and pathological conditions. A unique feature of CS/DS proteoglycans is the presence of iduronic acid (IdoA), catalyzed by two DS epimerases. Functional ablation of DS-epi1, the main epimerase in these cells, resulted in a major reduction of IdoA both on cell surface and in secreted CS/DS proteoglycans. Downregulation of IdoA led to delayed ability to re-populate wounded areas due to loss of directional persistence of migration. DS-epi1-/- aortic smooth muscle cells, however, had not lost the general property of migration showing even increased speed of movement compared to wild type cells. Where the cell membrane adheres to the substratum, stress fibers were denser whereas focal adhesion sites were fewer. Total cellular expression of focal adhesion kinase (FAK) and phospho-FAK (pFAK) was decreased in mutant cells compared to control cells. As many pathological conditions are dependent on migration, modulation of IdoA content may point to therapeutic strategies for diseases such as cancer and atherosclerosis.

Abstract
Capillary electrophoresis (CE) is a resourceful and versatile separation method for the analysis of complex carbohydrate mixtures. In combination with electrospray ionization (ESI) mass spectrometry (MS), CE enables fast, sensitive, and efficient separations for the accurate identification of a large variety of glycoform mixture types. In this chapter several reliable off- and on-line CE-based methods for the analysis of glycoforms with ESI MS/MS are presented. The first part of this chapter is dedicated to the application of off-line CE/ESI MS to complex mixtures of O-glycopeptides and mixtures of proteoglycan-derived O-glycans, i.e., glycosaminoglycans such as depolymerized hybrid chains of chondroitin sulfate (CS) and dermatan sulfate (DS). Procedures for off-line fractionation of these heterogeneous mixtures followed by ESI MS screening and sequencing of single glycoforms by collision-induced dissociation (CID) at low energies are also described. Ample sections are further devoted to on-line CE/ESI MS technique and its application to separation and identification of O-glycopeptides and CS/DS oligosaccharides. The concept and construction principles of two different sheathless CE/ESI MS interfaces together with the protocols to be applied for successful on-line analysis of O-glycopeptides and CS/DS oligosaccharides are presented in details in the last part of the chapter.

Abstract
Electrical and mechanical properties of dermatan sulfate (DS) molecules are studied in an aqueous environment as a function of pH. DS molecules linked at various points distributed on the surface of mica previously silanizated along with a suitable functionalized microsphere, attached to the cantilever of an atomic force microscope (AFM), provided suitable surfaces for testing interactions through the colloidal probe methodology. The repulsive force between the surfaces indicated that the charge of DS increases with pH as a result of the gradual deprotonation of acidic groups. Pulling experiments revealed increasing adhesion of DS to the monolayer as a function of pH, presumably due both to the electrical nature of the interaction between these molecules and the progressive increase of the charge of DS with pH. Serrations exhibited by the force in pulling experiments indicate that more than a single DS molecule is stretched at the same time. In addition, pulling force remained significant even at extensions that went beyond the average contour length of a single DS molecule, which suggests the existence of a significant link between DS molecules.

Abstract
This review emphasizes the importance of glycobiology in nature and aims to highlight, simplify and summarize the multiple functions and structural complexities of the different oligosaccharide combinatorial domains that are found in chondroitin sulphate/dermatan sulphate (CS/DS) glycosaminoglycan (GAG) chains. For example, there are 1008 different pentasaccharide sequences possible within CS, DS or CS/DS hybrid GAG chains. These combinatorial possibilities provide numerous potential ligand-binding domains that are important for cell and extracellular matrix interactions as well as specific associations with cytokines, chemokines, morphogens and growth factors that regulate cellular differentiation and proliferation during tissue development, for example, morphogen gradient establishment. The review provides some details of the large and diverse number of different enzymes that are involved in CS/DS biosynthesis and attempts to explain how differences in their expression patterns in different cell types can lead to subtle but important differences in the GAG metabolism that influence cellular proliferation and differentiation in development as well as regeneration and repair in disease. Our laboratory was the first to generate and characterize monoclonal antibodies (mAb) that very specifically recognize different ‘native’ sulphation motif/epitopes in CS/DS GAG chains. These monoclonal antibodies have been used to identify very specific spatio-temporal expression patterns of CS/DS sulphation motifs that occur during tissue and organ development (in particular their association with stem/progenitor cell niches) and also their recapitulated expression in adult tissues with the onset of degenerative joint diseases. In summary, diversity in CS/DS sulphation motif expression is a very important necessity for animal life as we know it.

Abstract
Chondroitin sulfate (CS) and dermatan sulfate (DS) glycosaminoglycans (GAGs) are covalently linked to proteins, building up a wide range of proteoglycans, with a prevalent expression in the extracellular matrix (ECM). In mammalian tissues, these GAG species are often found as hybrid CS/DS chains. Their structural diversity during chain elongation is produced by variability of sulfation in the repeating disaccharide units. In central nervous system, a large proportion of the ECM is composed of proteoglycans; therefore, CS/DS play a significant role in the functional diversity of neurons, brain development, and some brain diseases. A requirement for collecting consistent data on brain proteoglycan glycosylation is the development of adequate protocols for CS/DS extraction and detailed compositional and structure analysis. This chapter will present a strategy, which combines biochemical tools for brain CS/DS extraction, purification, and fractionation, with a modern analytical platform based on chip-nanoelectrospray multistage mass spectrometry (MS) able to provide information on the essential structural elements such as epimerization, chain length, sulfate content, and sulfation sites.

Abstract
The spatial distribution of collagen fibrils in the corneal stroma is essential for corneal transparency and is primarily regulated by extrafibrillar proteoglycans, which are multi-functional polymers that interact with hybrid type I/V collagen fibrils. In order to understand more about proteoglycan organisation and collagen associations in the cornea, three-dimensional electron microscopy reconstructions of collagen-proteoglycan interactions in the anterior, mid and posterior stroma from a Chst5 knockout mouse, which lacks a keratan sulphate sulphotransferase, were obtained. Both longitudinal and transverse section show sinuous, oversized proteoglycans with near-periodic, orthogonal off-shoots. In many cases, these proteoglycans traverse over 400nm of interfibrillar space interconnecting over 10 collagen fibrils. The reconstructions suggest that multiple chondroitin sulphate/dermatan sulphate proteoglycans have aggregated laterally and, possibly, end-to-end, with orthogonal extensions protruding from the main electron-dense stained filament. We suggest possible mechanisms as to how sulphation differences may lead to this increase in aggregation of proteoglycans in the Chst5-null mouse corneal stroma and how this relates to proteoglycan packing in healthy corneas.

Abstract
Early detection of mucopolysaccharidosis (MPS) is an important factor in treatment success; therefore, good disease biomarkers are vital. We evaluate heparin cofactor II-thrombin complex (HCII-T) as a biomarker in serum and dried blood spots (DBS) of MPS patients. Serum HCII-T and urine dermatan sulphate:chondroitin sulphate (DS:CS) ratio are also compared longitudinally against clinical outcomes in MPSI, II and VI patients following treatment. Samples were collected from MPS patients at the Royal Manchester Children's Hospital. DS:CS ratio was obtained by measuring the area density of spots from 2D electrophoresis of urinary glycosaminoglycans. Serum and DBS HCII-T was measured by sandwich ELISA. Serum HCII-T is elevated approximately 25-fold in MPS diseases that store DS, clearly distinguishing untreated MPSI, II and VI patients from unaffected age-matched controls. Serum HCII-T is also elevated in MPSIII, which leads to storage of heparan sulphate, with an increase of approximately 4-fold over unaffected age-matched controls. Urine DS:CS ratio and serum HCII-T decrease in response to treatment of MPSI, II and VI patients. HCII-T appears to respond rapidly to perturbations in treatment, whilst DS:CS ratio responds more slowly. HCII-T is a suitable biomarker for MPSI, II and VI, and it may also be informative for MPS diseases storing HS alone, such as MPSIII, although the elevation observed is smaller. In treated MPS patients, HCII-T and DS:CS ratio appear to measure short-term and long-term treatment outcomes, respectively. The potential value of HCII-T measurement in DBS for newborn screening of MPS diseases warrants further investigation.

Abstract
Electron transfer through gas phase ion-ion reactions has led to the widespread application of electron- based techniques once only capable in ion trapping mass spectrometers. Although any mass analyzer can in theory be coupled to an ion-ion reaction device (typically a 3-D ion trap), some systems of interest exceed the capabilities of most mass spectrometers. This case is particularly true in the structural characterization of glycosaminoglycan (GAG) oligosaccharides. To adequately characterize highly sulfated GAGs or oligosaccharides above the tetrasaccharide level, a high resolution mass analyzer is required. To extend previous efforts on an ion trap mass spectrometer, negative electron transfer dissociation coupled with a Fourier transform ion cyclotron resonance mass spectrometer has been applied to increasingly sulfated heparan sulfate and heparin tetrasaccharides as well as a dermatan sulfate octasaccharide. Results similar to those obtained by electron detachment dissociation are observed.

Abstract
Endogenous pleiotrophin and hepatocyte growth factor (HGF) mediate the neurite outgrowth-promoting activity of chondroitin sulfate (CS)/dermatan sulfate (DS) hybrid chains isolated from embryonic pig brain. CS/DS hybrid chains isolated from shark skin have a different disaccharide composition, but also display these activities. In this study, pleiotrophin- and HGF-binding domains in shark skin CS/DS were investigated. A high affinity CS/DS fraction was isolated using a pleiotrophin-immobilized column. It showed marked neurite outgrowth-promoting activity and strong inhibitory activity against the binding of pleiotrophin to immobilized CS/DS chains from embryonic pig brain. The inhibitory activity was abolished by chondroitinase ABC or B, and partially reduced by chondroitinase AC-I. A pentasulfated hexasaccharide with a novel structure was isolated from the chondroitinase AC-I digest using pleiotrophin affinity and anion exchange chromatographies. It displayed a potent inhibitory effect on the binding of HGF to immobilized shark skin CS/DS chains, suggesting that the pleiotrophin- and HGF-binding domains at least partially overlap in the CS/DS chains involved in the neuritogenic activity. Computational chemistry using molecular modeling and calculations of the electrostatic potential of the hexasaccharide and two pleiotrophin-binding octasaccharides previously isolated from CS/DS hybrid chains of embryonic pig brain identified an electronegative zone potentially involved in the molecular recognition of the oligosaccharides by pleiotrophin. Homology modeling of pleiotrophin based on a related midkine protein structure predicted the binding pocket of pleiotrophin for the oligosaccharides and provided new insights into the molecular mechanism of the interactions between the oligosaccharides and pleiotrophin.

Abstract
Glycosaminoglycans (GAGs) were extracted and purified from Wistar rat kidneys by two-step enzymatic hydrolysis and ion exchange chromatography. The sorts of GAGs were identified by electrophoresis on cellulose acetate membrane and separated on a weak anion-exchange column. Those purified GAGs were further totally hydrolyzed with specific glycosaminoglycan lyases. Their disaccharides composition and fine structures were analyzed with SAX-HPLC. The results indicated that GAGs in rat kidneys were mainly composed of heparan sulfate and small amount of dermatan sulfate. Eight kinds of disaccharides were found in heparan sulfate, and the content of acetyl-containing disaccharides was 77.6%, while nonsulfated disaccharides were 59.7%. In dermatan sulfate, six kinds of disaccharides were found. The content of monosulfated disaccharides was 49.8%, and nonsulfated disaccharides were 32.9%.

Abstract
One of the barriers to understanding structure-property relations for glycosaminoglycans has been the lack of constructive interplay between the principles and methodologies of the life sciences (molecular biology, biochemistry and cell biology) and the physical sciences, particularly in the field of polyelectrolytes. To address this, we first review the similarities and differences between the physicochemical properties of GAGs and other statistical chain polyelectrolytes of both natural and abioitic origin. Since the biofunctionality and regulation of the structures of GAGs is intimately connected with interactions with their cognate proteins, we particularly compare and contrast aspects of protein binding, i.e. effects of both GAGs and other polyelectrolytes on protein stability, protein aggregation and phase behavior. The protein binding affinities and their dependences on pH and ionic strength for the two groups are discussed not only in terms of observable differences, but also with regard to contrasting descriptions of the bound state and the role of electrostatics. We conclude that early studies of the heparin-Antithromin system, proceeding to a large extent through the methods and models of protein chemistry and drug discovery, established not only many enabling precedents but also constraining paradigms. Current studies on heparan sulfate and chondroitin sulfate seem to reflect a more ecumenical view likely to be more compatible with concepts from physical and polymer chemistry.

Abstract
Chondroitin/dermatan sulfate (CS/DS) glycosaminoglycans (GAGs) are present in high levels in connective tissue where they play roles as structural molecules and in protein-binding interactions. Recent developments in the techniques for analysis of CS/DS using capillary electrophoresis (CE) have enabled progress in the understanding of changes in CS/DS structure that accompany connective tissue diseases including osteoarthritis. Key to these developments is the ability to extract CS/DS GAGs from small quantities of connective tissue. This chapter describes a method for connective tissue GAG extraction, derivatization, and workup for subsequent capillary electrophoretic and/or mass spectrometric analysis.

Abstract
This study aims to evaluate the effects of the two most widely used glycosaminoglycans (dermatan sulphate and heparin) on both the structural and biological properties of collagen-based modified membranes (COL/GAGs membranes) designed for tissue engineering. The molecular weight of dermatan sulphate and heparins was correlated with the membrane feasibility and the cell (fibroblasts and keratinocytes) ability to adhere and proliferate on the COL/GAG membranes. Microstructure and physico-chemical properties of COL/GAGs membranes were examined using scanning electron microscopy and differential scanning calorimetry; the free amino group content and the swelling properties were also detected. The morphology, proliferation and growth behaviour of keratinocytes and fibroblasts were investigated using microscopical approach and in vitro colorimetric assay. Both fibroblasts and keratinocytes are able to grow and proliferate on COL/dermatan sulphate membranes. Fibroblasts revealed significantly higher proliferation on the membranes prepared with heparin if compared to the proliferation on the membrane without heparin (COL membrane). Particularly, a combination of the membranes formulated adding high molecular weight dermatan sulphate and high molecular weight heparin could be suitable to be used as biomaterials for epidermal substitute.

Abstract
Oversulphated Chondroitin Sulphate (OSCS) and Dermatan Sulphate (DS) in unfractionated heparins can be identified by nuclear magnetic resonance spectrometry (NMR). The limit of detection (LoD) of OSCS is 0.1% relative to the heparin content. This LoD is obtained at a signal-to-noise ratio (S/N) of 2000:1 of the heparin methyl signal. Quantification is best obtained by comparing peak heights of the OSCS and heparin methyl signals. Reproducibility of less than 10% relative standard deviation (RSD) has been obtained. The accuracy of quantification was good.

Abstract
INTRODUCTION A novel dermatan sulfate (DS) from the skin of the ray Raja radula with high anticoagulant activity was identified and its monosaccharide composition and anticoagulant mode of action and potency were determined. MATERIALS AND METHODS The DS isolated from the ray skin was identified by chondroitinase treatment and characterized by FT-IR and (1)H NMR spectroscopy. Its anticoagulant activity was checked by activated partial thromboplastin time (aPTT), thrombin time (TT), thrombin generation (TG), heparin cofactor II (HCII) and antithrombin (AT)-mediated inhibition of thrombin. The effects on platelet activation and aggregation were investigated using flow cytometry and aggregometry, respectively. RESULTS Chemical backbone structures of DS from Raja radula were close to that of DS from porcine intestinal mucosa. However, (1)H NMR indicated that iduronic acid was the major hexuronic acid moiety in the ray skin DS and also suggested that the amount of 2-O-sulfonated iduronic acid was higher in comparison with mammalian DS along with the occurrence of 4-O-sulfonated N-acetylgalactosamine residues. The anticoagulant effect of the ray skin DS was mainly due to the potentiation of thrombin inhibition by HCII but also, although to a lesser extent, by AT and was higher than that of the DS standard. Moreover, it had no effect on platelet activation and aggregation induced by various agonists. CONCLUSION Altogether, these results indicated that DS from raja radula skin is an anticoagulant drug of interest potentially useful in anticoagulant therapy.

Abstract
The structural characterization of glycosaminoglycans (GAG) oligosaccharides has been a long-standing challenge in the field of mass spectrometry. In this work, we present the application of electron detachment dissociation (EDD) Fourier transform mass spectrometry to the analysis of dermatan sulfate (DS) oligosaccharides up to 10 residues long. The EDD mass spectra of DS oligosaccharides were compared with their infrared multiphoton dissociation (IRMPD) mass spectra. EDD produces more abundant fragmentation than IRMPD with far less loss of SO3 from labile sulfate modifications. EDD cleaves all glycosidic bonds, yielding both conventional glycosidic bond fragmentation as well as satellite peaks resulting from the additional loss of 1 or 2 hydrogen atoms. EDD also yields more cross-ring fragmentation than IRMPD. For EDD, abundant cross-ring fragmentation in the form of A- and X-ions is observed, with 1,5Xn cleavages occurring for all IdoA residues and many of the GalNAc4S residues, except at the reducing and nonreducing ends. In contrast, IRMPD produces only A-type cross-ring fragmentation for long oligosaccharides (dp6-dp10). As all the structurally informative fragment ions observed by IRMPD appear as a subset of the peaks found in the EDD mass spectrum, EDD shows great potential for the characterization of GAG oligosaccharides using a single tandem mass spectrometry experiment.

Abstract
The solution conformation behavior of a dermatan-derived tetrasaccharide--Delta HexA-(1-->3)-GalNAc4S-beta-(1-->4)-IdoA-alpha-(1-->3)-red-GalNAc4S (S is a sulfate group)--has been explored by means of NMR spectroscopy, especially by NOE-based conformational analysis. The tetrasaccharide was present as four species, two of which are chemically different in the anomeric orientation of the reducing 2-deoxy-2-acetamido-galactose (red-GalNAc) residue, while the other two are the result of different conformations of the iduronic acid (IdoA) unit. The two alpha-beta-interconverting anomers were present in a 0.6:1 ratio. Ring conformations have been defined by analysis of (3)J(H,H) coupling constants and interresidual NOE contacts. Both 2-deoxy-2-acetamido-galactose (GalNAc) residues were found in the (4)C(1) chair conformation, the unsaturated uronic acid (Delta-Hex A) adopts a strongly predominant half-chair (1)H(2) conformation, while the IdoA residue exists either in the (1)C(4) chair or in the (2)S(0) skewed boat geometries, in a 4:1 ratio. There is a moderate flexibility of Phi and Psi torsions as suggested by nuclear Overhauser effects (NOEs), molecular modeling (MM), and molecular dynamics (MD) studies. This was further investigated by residual dipolar couplings (RDCs). One-bond C--H RDCs ((1)D(C,H)) and long-range H-H ((3)D(H,H)) RDCs were measured for the tetrasaccharide in a phage solution and interpreted in combination with restrained MD simulation. The RDC-derived data substantially confirmed the validity of the conformer distribution resulting from the NOE-derived simulations, but allowed an improved definition of the conformational behavior of the oligosaccharides in solution. In summary, the data show a moderate flexibility of the four tetrasaccharide species at the central glycosidic linkage. Differences in the shapes of species with the IdoA in skew and in chair conformations and in the distribution of the sulfate groups have also been highlighted.

Abstract
Dermatan sulfate (DS) widespread as a component of extracellular matrix proteoglycans, is characterized by great bio-reactivity and remarkable structural heterogeneity due to distinct degrees of sulfation and glucuronosyl epimerization and different polymerization degrees. However, DS metabolism under various biological conditions is poorly known. Dupuytren's contracture is a benign fibromatosis leading to complex remodeling of the palmar fascia structure and properties. However, it remains unclear whether the disease affects the structure of DS, which is the major tissue glycosaminoglycan. Thus the aim of the study was to examine the structure of the total DS in Dupuytren's fascia. DS chains were extracted from 5 samples of normal fascia and 7 specimens of Dupuytren's tissue by papain digestion followed by fractionation with cetylpyridinium chloride. Then, DS structure analysis was performed comprising the evaluation of its molecular masses and sensitivity to hyaluronidase and chondroitinase B. Dupuytren's contracture is associated with significant remodeling of DS chain structure revealed by (1) a distinct profile of chain molecular masses characterized by the appearance of long size components as well as the increase in the content of small size chains; (2) a different glucuronosyl epimerization pattern connected with the enhanced content of glucuronate disaccharide blocks; (3) chain oversulfation. These structural alterations in total DS may modify the GAG interactions especially affecting collagen fibrillogenesis and growth factor availability. Thus, Dupuytren's contracture associated DS remodeling may promote the phenomena typical for advanced disease: apoptosis and reduction in cell number as well as the appearance of dense pseudotendinous collagen matrix.

Abstract
Heparan sulfate has been isolated for the first time from the mosquito Anopheles stephensi, a known vector for Plasmodium parasites, the causative agents of malaria. Chondroitin sulfate, but not dermatan sulfate or hyaluronan, was also present in the mosquito. The glycosaminoglycans were isolated, from salivary glands and midguts of the mosquito in quantities sufficient for disaccharide microanalysis. Both of these organs are invaded at different stages of the Plasmodium life cycle. Mosquito heparan sulfate was found to contain the critical trisulfated disaccharide sequence, -->4)beta-D-GlcNS6S(1-->4)-alpha-L-IdoA2S(1-->, that is commonly found in human liver heparan sulfate, which serves as the receptor for apolipoprotein E and is also believed to be responsible for binding to the circumsporozoite protein found on the surface of the Plasmodium sporozoite. The heparan sulfate isolated from the whole mosquito binds to circumsporozoite protein, suggesting a role within the mosquito for infection and transmission of the Plasmodium parasite.

Abstract
Hyaluronan and sulfated glycosaminoglycans, as intrinsic components of proteoglycans, are playing important roles in cancer biology. In the present study, we investigated in detail the glycosaminoglycans on both fine chemical and structural levels in laryngeal cartilaginous and non-cartilaginous tissues at different stages of laryngeal cancer. The results indicated that in cartilaginous tissues the amounts of chondroitin sulfate, keratan sulfate, dermatan sulfate and hyaluronan presented a dramatic decrease in contrast to the non-cartilaginous tissues, which showed a significant increase of these glycosaminoglycans compared to their normal counterparts. On fine chemical structure, the molar ratios of 4-sulfated to 6-sulfated and non-sulfated to sulfated disaccharides from both cartilaginous and non-cartilaginous cancerous tissues showed a significant increase. On molecular-size level, in laryngeal cancer, the chromatographic behaviour of the sulfated glycosaminoglycan chains from both tissue-types revealed their lower M(r) with a more polydisperse and heterogeneous distribution compared to the normal ones. In addition, in both tissues, a significant decrease of high molecular-size hyaluronan was observed. Of particular interest was the great increase of hyaluronan of low molecular mass in the laryngeal non-cartilaginous tissues, which ranged from 330 to 890 kDa. The kind and the extent of these alterations, which presented an intense stage-related behaviour, depended on the tissue origin and could be associated with the malignant phenotype of human laryngeal cancer.

Abstract
Chondroitin sulfate (CS) and dermatan sulfate (DS) have been implicated in the processes of neural development in the brain. In this study, we characterized developmentally regulated brain CS/DS chains using a single chain antibody, GD3G7, produced by the phage display technique. Evaluation of the specificity of GD3G7 toward various glycosaminoglycan preparations showed that this antibody specifically reacted with squid CS-E (rich in the GlcUAbeta1-3GalNAc(4,6-O-sulfate) disaccharide unit E), hagfish CS-H (rich in the IdoUAalpha1-3GalNAc(4,6-O-sulfate) unit iE), and shark skin DS (rich in both E and iE units). In situ hybridization for the expression of N-acetylgalac-tosamine-4-sulfate 6-O-sulfotransferase in the postnatal mouse brain, which is involved in the biosynthesis of CS/DS-E, showed a widespread expression of the transcript in the developing brain except at postnatal day 7, where strong expression was observed in the external granule cell layer in the cerebellum. The expression switched from the external to internal granule cell layer with development. Immunohistochemical localization of GD3G7 in the mouse brain showed that the epitope was relatively abundant in the cerebellum, hippocampus, and olfactory bulb. GD3G7 suppressed the growth of neurites in embryonic hippocampal neurons mediated by CS-E, suggesting that the epitope is embedded in the neurite outgrowth-promoting motif of CS-E. In addition, a CS-E decasaccharide fraction was found to be the critical minimal structure needed for recognition by GD3G7. Four discrete decasaccharide epitopic sequences were identified. The antibody GD3G7 has broad applications in investigations of CS/DS chains during the central nervous system's development and under various pathological conditions.

Abstract
We determined the disaccharide composition of dermatan sulfate (DS) purified from the skin of the electric eel Electrophorus electricus. DS obtained from the electric eel was composed of non-sulfated, mono-sulfated disaccharides bearing esterified sulfate groups at positions C-4 or C-6 of N-acetyl galactosamine (GalNAc), and disulfated disaccharides bearing esterified sulfate groups at positions C-2 of the uronic acid and at position C-4 or C-6 of GalNAc. The anticoagulant, antithrombotic and bleeding effects of electric eel skin DS were compared to those of porcine DS and also to those described previously for DS purified from skin of eel, Anguilla japonica. DS from electric eel is a potent anticoagulant due to a high heparin co-factor II (HC II) activity. The electric eel DS has a higher potency to prevent thrombus formation on an experimental model and a lower bleeding effect in rats than the porcine DS. Interestingly, it was recently demonstrated that DS obtained from skin of the eel Anguilla japonica, which possesses a disaccharide composition very similar to that of electric eel skin DS described here, did not show anticoagulant activity. Thus, the anticoagulant activity of electric eel skin DS is not merely a consequence of its charge density. We speculate that the differences among the anticoagulant activities of these three DS may be related to different arrangements of the disulfated disaccharide domain for binding to HC II within their polysaccharide chains and that it may be more efficiently arranged along the carbohydrate chain in electric eel skin DS than in the two other types of DS.

Abstract
We established a highly sensitive liquid chromatography tandem mass spectrometry (LC-MS/MS) method to analyze the disaccharides produced from keratan sulfate (KS), heparan sulfate (HS), and dermatan sulfate (DS). It was revealed that KS, HS, and DS in human serum and plasma were digested to each disaccharide by keratanase II, heparitinase, and chondroitinase B, respectively. Analysis of disaccharides was performed by LC-MS/MS with multiple reactions monitoring in the negative ion mode. Separation of LC was performed on a Hypercarb (2.0 mm i.d.x150 mm, 5 microm) with a gradient elution of acetonitrile-0.01M ammonium bicarbonate (pH 10). The mobile phase flow rate was 0.2ml/min. An API-4000 mass spectrometer equipped with a turbo ionspray was used to determine each glycosaminoglycan (GAG) in the serum of control subjects and plasma of mucopolysaccharidose (MPS) patients. The intraday precision expressed as a coefficient of variation was within 15.8% for five replicate analyses with three human control samples. The interday (overall, n=15) precision was within 14.8% for 3 days. This method is sensitive and reproducible, and it would be useful for clinical diagnosis.

Abstract
Conjugating a single glycosaminoglycan (GAG) species such as chondroitin-6-sulfate (CSC) to chitosan is beneficial to chondrocyte culture and extracellular matrix (ECM) production, but whether fabrication of 3D chitosan scaffolds with additional minor GAG species such as dermatan sulfate (DS) further improves the ECM production is unknown. In this study, Response Surface Methodology (RSM) was employed to design CSC/DS/chitosan scaffolds of various formulations for cartilage engineering and to investigate the roles of individual GAG species in cartilage formation. The CSC/DS formulation affected neither the physical properties of scaffolds nor cell adhesion, but influenced cell morphology, GAGs and collagen production and chondrocytic gene expression. The linear effects elucidated by RSM analysis suggested that within the level range higher CSC levels favored GAGs and collagen production, whereas lower DS levels were desired for these responses. Nonetheless, the quadratic effects of DS and two-way interactions between CSC and DS also contributed to the GAGs and collagen production. Accordingly, the optimal formulation, as predicted by RSM and validated by experiments, comprised 2.8 mg CSC and 0.01 mg DS per scaffold. This study confirmed the importance of DS in cartilage tissue engineering and implicated the feasibility of rational CSC/DS/chitosan scaffold design with the aid of RSM.

Abstract
A family of proteins designated BSP-A1, BSP-A2, BSP-A3, and BSP-30-kDa, collectively called BSP (bovine seminal plasma) proteins, constitute the major protein fraction of bull seminal plasma. BSP proteins can stimulate sperm capacitation by inducing cholesterol and phospholipid efflux from sperm. Boar seminal plasma contains one homologous protein of the BSP family, named pB1; however, its physiological role is still unknown. In the current study, we report a novel method to purify pB1 from boar seminal plasma by chondroitin sulfate B-affinity chromatography and reverse-phase-high performance liquid chromatography. We also studied the effect of pB1, BSP-A1/-A2, and whole boar seminal plasma on boar sperm capacitation. Boar epididymal sperm were washed, preincubated in noncapacitating medium containing pB1 (0, 2.5, 5, 10 or 20 microg/ml), BSP-A1/-A2 (0 or 20 microg/ml) proteins, or whole seminal plasma (0, 250, 500, or 1000 microg/ml), then washed and incubated in capacitating medium. Acrosomal integrity was assessed by chlortetracycline staining. The status of sperm capacitation was evaluated by the capacity of sperm to undergo the acrosome reaction initiated by the addition of the calcium ionophore, A23187. The pB1 and BSP-A1/-A2 proteins increased epididymal sperm capacitation as compared with control (sperm preincubated without proteins). This effect reached a maximum level at 10 microg/ml pB1 and at 20 microg/ml BSP-A1/-A2 (2.3- and 2.2-fold higher than control, respectively). Whole boar seminal plasma did not induce sperm capacitation. In addition, pB1 bound to boar epididymal sperm and was lost during capacitation. These results indicate that BSP proteins and their homologs in other species induce sperm capacitation in a similar way.

Abstract
This review will discuss the importance of sequencing long chondroitin sulfate and dermatan sulfate chains specifically derived from decorin. Decorin is a member of the small leucine-rich repeat proteoglycans and ubiquitously expressed primarily in the skin. Sequence information and diverse function of glycosaminoglycans is further influenced by variable expression through the core protein indicating the importance to analyse glycosaminoglycans from specific proteoglycans.

Abstract
Glycosaminoglycans from the ventral and dorsal integuments of the anuran Bufo ictericus were characterized based on biochemical and histochemical methods. Dermatan sulfate is the major metachromatic glycosaminoglycan found in these tissues, but small amount of heparan sulfate was also detected. The average molecular mass of the dermatan sulfate is approximately 20 kDa, similar to the glycosaminoglycan isolated from mammalian skin. In addition, the amphibian integument contains high amounts of hyaluronic acid, especially in the ventral area. We also observed that the glycosaminoglycans occur in the anuran integument as irregular deposits through the spongious dermis and in the mast cells, as revealed by histochemical analysis using Alcian blue, dimethylmethylene blue and toluidine blue stains. The concentration and composition of glycosaminoglycans found in the amphibian integument resemble those from mammalian skin except for the higher concentration of hyaluronic acid in the amphibian tissue. Possibly, this observation indicates that the function of the sulfated glycosaminoglycan in these tissues has been preserved during evolution, although the amphibian integument and the human skin have their own particular physiology.
