Abstract
Chondroitin sulfate (CS) has widely been used as a symptomatic slow-acting drug or a dietary supplement for the treatment and prevention of osteoarthritis. However, CS could not be absorbed after oral intake due to its polyanionic nature and large molecular weight. Gut microbiota has recently been proposed to play a pivotal role in the metabolism of drugs and nutrients. Nonetheless, how CS is degraded by the human gut microbiota has not been fully characterized. In the present study, we demonstrated that each human gut microbiota was characterized with a unique capability for CS degradation. Degradation and fermentation of CS by the human gut microbiota produced significant amounts of unsaturated CS oligosaccharides (CSOSs) and short-chain fatty acids. To uncover which microbes were responsible for CS degradation, we isolated a total of 586 bacterial strains with a potential CS-degrading capability from 23 human fecal samples. Bacteroides salyersiae was a potent species for CS degradation in the human gut microbiota and produced the highest amount of CSOSs as compared to other well-recognized CS-degraders, including Bacteroides finegoldii, Bacteroides thetaiotaomicron, Bacteroides xylanisolvens, and Bacteroides ovatus. Genomic analysis suggested that B. salyersiae was armed with multiple carbohydrate-active enzymes that could potentially degrade CS into CSOSs. By using a spent medium assay, we further demonstrated that the unsaturated tetrasaccharide (udp4) produced by the primary degrader B. salyersiae could serve as a "public goods" molecule for the growth of Bacteroides stercoris, a secondary CS-degrader that was proficient at fermenting CSOSs but not CS. Taken together, our study provides insights into the metabolism of CS by the human gut microbiota, which has promising implications for the development of medical and nutritional therapies for osteoarthritis.

Abstract
Chondroitin sulfate has been widely administered orally to improve knee osteoarthritis. Chondroitin sulfate also has various biological properties, such as anti-inflammatory, immunomodulatory, anti-oxidative, and antitumor activity. However, chondroitin sulfate absorption in the digestive system and bioavailability remains controversial owing to its large molecular weight. In this study, we aimed to evaluate the absorption of chondroitin sulfate oligosaccharides, depolymerized chondroitin sulfate with low molecular weight, in oral administration to humans. Four types of chondroitin sulfate with varying molecular weight [chondroitin sulfate tetrasaccharide (MW. 980), CSOS-1 (MW. 1,500), CSOS-2 (MW. 2,800), and HMWCS (MW. 70,000)] were orally administered and quantified in plasma and urine. Exogenous chondroitin sulfate in these samples was quantified using a high-performance liquid chromatography system equipped with a fluorescence detector. Quantitative changes of administered chondroitin sulfate tetrasaccharide showed similar patterns in plasma and urine, therefore it was presumed that the amount of exogenous chondroitin sulfate excreted in urine reflects its quantitative profile in blood. Considering urinary exogenous chondroitin sulfate as a parameter of intestinal chondroitin sulfate absorption, urinary contents of orally administered chondroitin sulfate with varying molecular weight were compared. Consequently, the amount of urinary exogenous chondroitin sulfate in 24 h after administration was higher in the chondroitin sulfate oligosaccharides group than that in the high molecular weight chondroitin sulfate group. Additionally, in the molecular weight distribution, urinary exogenous chondroitin sulfate after chondroitin sulfate oligosaccharides administration showed a lower content of chondroitin sulfate oligosaccharides with a higher molecular weight than that observed before administration. In summary, our results demonstrated for the first time that lower molecular weight of chondroitin sulfate is more efficiently absorbed through the digestive tract in human, and the improvement of its bioavailability is expected.

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
The heparin family, which includes unfractionated heparin, low-molecular heparin, and fondaparinux, is a class of drugs clinically used as intravenous blood thinners. To date, issues related to both the reversal of anticoagulation and the blood level determination of the anticoagulant at the point-of-care remain: while the only U.S. Food and Drug Administration (FDA) approved antidote for heparin displays serious efficacy and safety drawbacks, the current assays for heparin monitoring are indirect measurements subject to their own limitations and variations. Herein, we provide an update on the numerous recent chemical approaches to tackle these issues, from which it is clear that some new antidotes and sensors for heparin certainly have the potential to exceed current clinical standards. This review aims to review a field that requires close collaborations between physicians, biologists, and chemists in order to foster advances toward clinical translation.

Abstract
Human antithrombin (AT) has two isoforms of which the predominant α-form is glycosylated on all four possible glycosylation sites and the lower abundant β-isoform lacks the oligosaccharide on Asn135. The main oligosaccharide structure of human AT consists of biantennary complex-type oligosaccharides lacking a core fucose. Generally, Chinese hamster ovary (CHO) cells produce recombinant human AT (rhAT) with core-fucosylated oligosaccharides. However, rhAT lacking core-fucose oligosaccharides can be produced by POTELLIGENT® technology, which uses FUT8 knockout CHO cells in production. The rhAT has more variable glycan structures, such as tetra-antennary complex type, high-mannose type, and mannose 6-phosphate species as minor components compared to plasma-derived human AT (phAT). In addition, the site-specific glycan profile was different between two ATs. We evaluated the effect of these properties on efficacy and safety based on a comparison of rhAT made by that technology with phAT in terms of their respective oligosaccharide structures, site-specific oligosaccharide profiles, and the ratio of α- and β-forms. Although some structural differences were found between the rhAT and phAT, we concluded that these differences have no significant effect on the efficacy and safety of rhAT.

Abstract
OBJECTIVE To quantify the magnitude and duration of changes in urine chondroitin sulfate concentration (uCS) as a result of oral administration of a chondroitin sulfate-containing supplement in dogs. ANIMALS 8 healthy privately owned dogs. PROCEDURES A urine sample was collected from each dog via cystocentesis on day 1; free-catch midstream urine samples were collected once daily on days 2 through 5. Pretreatment uCS was established from those samples. Each dog then received a chondroitin sulfate-containing supplement (20 to 30 mg/kg, PO, q 12 h) for 8 days (on days 7 through 14). Urine samples were collected on days 8 through 12 and day 15. For each sample, uCS was quantified by liquid chromatography-tandem mass spectrometry. Variable urine concentration was accounted for by dividing the uCS by urine creatinine concentration (uCrea) to determine the uCS:uCrea ratio. Pretreatment uCS:uCrea ratios were compared with treatment uCS:uCrea ratios to calculate the fold change in uCS after supplement administration. RESULTS Among the study dogs, oral administration of the chondroitin sulfate-containing supplement resulted in a 1.9-fold increase in the median uCS:uCrea ratio. Data obtained on days 8 through 12 and day 15 indicated that the daily increase in uCS remained consistent and was not additive. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that oral administration of supplemental chondroitin sulfate to dogs modestly increased uCS within 24 hours; however, subsequent supplement administration did not have an additive effect. A potential therapeutic benefit of persistently increased uCS in preventing recurrent urinary tract infections in dogs warrants investigation.

Abstract
Background Exfoliative glaucoma (XFG) is typically classified as a high-pressure type of secondary open-angle glaucoma that develops as a consequence of exfoliation syndrome (XFS). Exfoliation syndrome is an age-related, generalized disorder of the extracellular matrix characterized by production and progressive accumulation of a fibrillar exfoliation material (XFM) in intra- and extraocular tissues. Exfoliation material represents complex glycoprotein/proteoglycan structure composed of a protein core surrounded by glycosaminoglycans such as heparan sulfate (HS) and chondroitin sulfate (CS). The purpose of the present study was to investigate HS and CS concentrations in serum samples of patients with newly diagnosed XFG and compare the obtained values with those pertaining to newly diagnosed primary open-angle glaucoma (POAG), normal controls (NC) and subjects with XFS. Methods This case–control study involved 165 subjects, including patients with newly diagnosed XFG, patients with newly diagnosed POAG, subjects with XFS and age- and sex-matched NC. The study was conducted at the Glaucoma Department of Clinic for Eye Diseases, Clinical Centre of Serbia, as the referral center for glaucoma in Serbia. Results The mean age in the XFG, POAG, XFS and NC groups was 73.3 ± 9.0, 66.3 ± 7.8, 75.5 ± 7.0 and 73.5 ± 9.5 years, respectively, XFG vs. POAG, p < 0.001. Mean serum HS concentrations in the XFG, POAG, NC and XFS groups were 3,189.0 ± 1,473.8 ng/mL, 2,091.5 ± 940.9 ng/mL, 2,543.1 ± 1,397.3 ng/mL and 2,658.2 ± 1,426.8 ng/mL respectively, XFG vs. POAG, p = 0.001 and XFG vs. NC, p = 0.032. Mean serum CS concentrations in the XFG, POAG, NC and XFS group were 43.9 ± 20.7 ng/mL, 38.5 ± 22.0 ng/mL, 35.8 ± 16.4 ng/mL and 43.3 ± 21.8 ng/mL, respectively, XFG vs. NC, p = 0.041. Conclusions Our findings revealed greater HS and CS concentrations in XFG patients and XFS subjects compared to those without XFM. Implications of HS and CS in the pathophysiology of XFS and glaucoma should be studied further. Serum is easily accessible and should thus be explored as rich sources of potential biomarkers. Further research should aim to identify XFG biomarkers that could be utilized in routine blood analysis tests, aiding in timely disease diagnosis.

Abstract
The pharmacokinetic profile of a new 800-mg tablet of nonanimal chondroitin sulfate (CS) (Mythocondro®, 800-mg tablets, Gnosis S.p.A., Italy) was investigated vs an animal CS in healthy volunteers for a total period of 48 hours. After a single 2400-mg dose of the test and the reference formulation, total CS, the compositional disaccharides (ΔDi6S, ΔDi4S and ΔDi0S), and the overall charge density were quantified in plasma. The safety and tolerability profile after a single dose of this new nonanimal CS tablets was excellent. After baseline-corrected concentrations, an overall greater plasma concentration was observed after 24 hours of ∼44% and after 48 hours of ∼45% from administration of nonanimal when compared to animal-derived CS. Moreover, nonanimal CS increases the specific sulfation in the 6-position of N-acetyl-galactosamine in human plasma CS and, as a consequence, the overall charge density, reaching double values (0.91), after 48 hours compared to bovine CS and to endogenous CS. In conclusion, nonanimal CS, possessing a lower molecular weight than an animal-derived sample, produces a greater CS concentration for a more prolonged period of time in plasma and an increase in charge density and specific 6-sulfation of endogenous plasma CS.

Abstract
We report that a "tree-like" polymer of lysine is able to form a multi-ligand complex with a fluorescently labelled peptide, leading to the almost complete extinction of the optical signal that can be restored upon the introduction of heparin. This simple system allows, for the first time, the turn-ON fluorescent sensing of the anticoagulant in human blood at clinically relevant levels.

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
The aim of this study was to examine the absorption of fucoidan through the intestinal tract. Fucoidan (0.1, 0.5, 1.0, 1.5 and 2.0 mg/mL) was added to Transwell inserts containing Caco-2 cells. The transport of fucoidan across Caco-2 cells increased in a dose-dependent manner up to 1.0 mg/mL. It reached a maximum after 1 h and then rapidly decreased. In another experiment, rats were fed standard chow containing 2% fucoidan for one or two weeks. Immunohistochemical staining revealed that fucoidan accumulated in jejunal epithelial cells, mononuclear cells in the jejunal lamina propria and sinusoidal non-parenchymal cells in the liver. Since we previously speculated that nitrosamine may enhance the intestinal absorption of fucoidan, its absorption was estimated in rats administered N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) in their drinking water. Rats were fed 0.2% fucoidan chow (BBN + 0.2% fucoidan rats), 2% fucoidan chow (BBN + 2% fucoidan rats) and standard chow for eight weeks. The uptake of fucoidan through the intestinal tract seemed to be low, but was measurable by our ELISA method. Fucoidan-positive cells were abundant in the small intestinal mucosa of BBN + 2% fucoidan rats. Most fucoidan-positive cells also stained positive for ED1, suggesting that fucoidan was incorporated into intestinal macrophages. The uptake of fucoidan by Kupffer cells was observed in the livers of BBN + 2% fucoidan rats. In conclusion, the absorption of fucoidan through the small intestine was demonstrated both in vivo and in vitro.

Abstract
Glycosaminoglycans (GAGs) due to their hydrophilic character and high anionic charge densities play important roles in various (patho)physiological processes. The identification and quantification of GAGs in biological samples and tissues could be useful prognostic and diagnostic tools in pathological conditions. Despite the noteworthy progress in the development of sensitive and accurate methodologies for the determination of GAGs, there is a significant lack in methodologies regarding sample preparation and reliable fast analysis methods enabling the simultaneous analysis of several biological samples. In this report, developed protocols for the isolation of GAGs in biological samples were applied to analyze various sulfated chondroitin sulfate- and hyaluronan-derived disaccharides using fluorophore-assisted carbohydrate electrophoresis (FACE). Applications to biologic samples of clinical importance include blood serum, lens capsule tissue and urine. The sample preparation protocol followed by FACE analysis allows quantification with an optimal linearity over the concentration range 1.0–220.0 µg/mL, affording a limit of quantitation of 50 ng of disaccharides. Validation of FACE results was performed by capillary electrophoresis and high performance liquid chromatography techniques.

Abstract
Human cysteine cathepsin S (catS) participates in distinct physiological and pathophysiological cellular processes and is considered as a valuable therapeutic target in autoimmune diseases, cancer, atherosclerosis, and asthma. We evaluated the capacity of negatively charged glycosaminoglycans (heparin, heparan sulfate, chondroitin 4/6-sulfates, dermatan sulfate, and hyaluronic acid) to modulate the activity of catS. Chondroitin 4-sulfate (C4-S) impaired the collagenolytic activity (type IV collagen) and inhibited the peptidase activity (Z-Phe-Arg-AMC) of catS at pH 5.5, obeying a mixed-type mechanism (estimated Ki = 16.5 ± 6 μM). Addition of NaCl restored catS activity, supporting the idea that electrostatic interactions are primarly involved. Furthermore, C4-S delayed in a dose-dependent manner the maturation of procatS at pH 4.0 by interfering with the intermolecular processing pathway. Binding of C4-S to catS was demonstrated by gel-filtration chromatography, and its affinity was measured by surface plasmon resonance (equilibrium dissociation constant Kd = 210 ± 40 nM). Moreover, C4-S induced subtle conformational changes in mature catS as observed by intrinsic fluorescence spectroscopy analysis. Molecular docking predicted three specific binding sites on catS for C4-S that are different from those found in the crystal structure of the cathepsin K-C4-S complex. Overall, these results describe a novel glycosaminoglycan-mediated mechanism of catS inhibition and suggest that C4-S may modulate the collagenase activity of catS in vivo.

Abstract
Heparan sulfate (HS) is one of the most complex and informative biopolymers found on the cell surface or in the extracellular matrix as either free HS fragments or constituents of HS proteoglycans (HSPGs). Analysis of free HS and HSPG sugar chains in human serum at the disaccharide level has great potential for early disease diagnosis and prognosis; however, the low concentration of HS in human serum, together with the complexity of the serum matrix, limits the information on HS. In this study, we present and validate the development of a new sensitive method for in-depth compositional analysis of free HS and HSPG sugar chains. This protocol involved several steps including weak anion exchange chromatography, ultrafiltration, and solid-phase extraction for enhanced detection prior to LC-MS/MS analysis. Using this protocol, a total of 51 serum samples from 26 premenopausal and 25 postmenopausal women were analyzed. Statistically significant differences in heparin/HS disaccharide profiles were observed. The proportion of N-acetylation and N-sulfation in both free HS and HSPG sugar chains were significantly different between pre- and postmenopausal women, indicating changes in N-deacetylase/N-sulfotransferases (NDSTs), the enzymes involved in the initial step of the biosynthetic pathway. Differences in the proportion of 6-O-sulfation suggest that 6-O-sulfotransferase and/or 6-O-sulfatase enzymes may also be implicated.

Abstract
This study aimed to assess whether chronic administration of chondroitin sulfate (CS) affects baseline expression of cytochrome P450 isoforms and impedes the decrease in expression and activity of CYP1A2 and CYP3A6 in rabbits with a turpentine-induced inflammatory reaction (TIIR). Seven groups of 5 rabbits, 3 control groups and 4 receiving 20 mg/kg/day of CS for 20 and 30 days, were used. The rabbits of 1 control group and 2 groups receiving CS had a TIIR; finally, the rabbits of one of the control groups remained in the animal facilities for 30 days to assess the effect of time and environment on cytochrome P450. In control rabbits, intake of CS for 20 and 30 days did not affect CYP3A6, CYP1A2 and NADPH cytochrome P450 reductase (CPR) mRNA, protein expression and activity. Compared with control rabbits, the TIIR not only reduced mRNA, protein expression and activity of CYP3A6 and CYP1A2 but also that of CPR. In rabbits with TIIR, CS prevented the decrease of CYP3A6 expression but not the reduction in activity. CS did not impede TIIR-induced down-regulation of CYP1A2. Hepatic NO() concentrations and NF-κB nuclear translocation were increased by the TIIR, effect reversed by CS. In vitro, in hepatocytes, CS did not alter the expression and activity of CYP3A6, CYP1A2, and CPR. In conclusion, oral CS elicits a systemic effect but does not affect CYP1A2, CYP3A6, and CPR in control rabbits, although in rabbits with TIIR, CS prevents CYP3A6 protein down-regulation but not that of CYP1A2.

Abstract
The analysis of heparan sulfate glycosaminoglycans (HSGAGs) variations in human serum at the disaccharide level has a great potential for disease diagnosis and prognosis. However, the lack of available analytical methodology for the compositional analysis of HSGAGs in human serum remains to be addressed to delineate the possible role of HSGAGs on the onset and/or progression of a disease. In this study, we have developed a method for the in-depth compositional analysis of the 12 heparin/HS-derived disaccharides from human serum using a combination of technologies--fractionation, exhaustive digestion, solid phase extraction, and LC-MS/MS. The method exhibits high recovery (72-110%) and good reproducibility (standard deviation of less than 5%) with a low limit of detection and quantification. Errors from the method validation were within 1.1%. Nondetectable non- or low-sulfated disaccharides in human serum were also detected using the optimized protocol. Further applying this method, the comprehensive analysis of HSGAGs compositions in human sera from female donors showed considerable variations in disaccharide patterns and compositions.

Abstract
Background Exposure of chondroitin sulfate A (CS-A) on the surface of activated platelets is well established. The aim of the present study was to investigate to what extent CS-A contributes to the binding of the complement recognition molecule C1q and the complement regulators C1 inhibitor (C1INH), C4b-binding protein (C4BP), and factor H to platelets. Principal Findings Human blood serum was passed over Sepharose conjugated with CS-A, and CS-A-specific binding proteins were identified by Western blotting and mass spectrometric analysis. C1q was shown to be the main protein that specifically bound to CS-A, but C4BP and factor H were also shown to interact. Binding of C1INH was dependent of the presence of C1q and then not bound to CS-A from C1q-depleted serum. The specific interactions observed of these proteins with CS-A were subsequently confirmed by surface plasmon resonance analysis using purified proteins. Importantly, C1q, C4BP, and factor H were also shown to bind to activated platelets and this interaction was inhibited by a CS-A-specific monoclonal antibody, thereby linking the binding of C1q, C4BP, and factor H to exposure of CS-A on activated platelets. CS-A-bound C1q was also shown to amplify the binding of model immune complexes to both microtiter plate-bound CS-A and to activated platelets. Conclusions This study supports the concept that CS-A contributes to the binding of C1q, C4BP, and factor H to platelets, thereby adding CS-A to the previously reported binding sites for these proteins on the platelet surface. CS-A-bound C1q also seems to amplify the binding of immune complexes to activated platelets, suggesting a role for this molecule in immune complex diseases.

Abstract
The purpose of this study was to determine the absorption, distribution and excretion of (99m)technetium-labeled, high-molecular-weight hyaluronan (((99m)Tc-HA) and (99m)technetium pertechnetate ((99m)Tc-P) after single dose, oral administration to Wistar rats and Beagle dogs. A pilot study utilized (99m)Tc-HA alone, and a second confirmatory study compared uptake of labeled (99m)Tc-HA with (99m)Tc-P. Urinary and fecal excretion after (99m)Tc-HA ingestion by rats showed 86.7-95.6% of radioactivity was recovered, almost all in feces. All tissues examined showed incorporation of radioactivity from (99m)Tc-HA starting at 15 min and persisting for 48 h, in a pattern significantly different from (99m)Tc-P. Whole-body scintigraphs and close-ups of the ventral chest region showed nonalimentary radioactivity from (99m)Tc-HA concentrated in joints, vertebrae and salivary glands four hours after administration. Autoradiography of skin, bone and joint tissue pieces after 24 h showed incorporation of radioactivity from (99m)Tc-HA, but not from (99m)Tc-P. Conversely, absorption, distribution and excretion of (99m)Tc was completely different from (99m)Tc-HA, showing an expected pattern of rapid absorption and excretion in urine, with accumulation in thyroid glands, stomach, kidney and bladder. This report presents the first evidence for uptake and distribution to connective tissues of orally administered, high-molecular-weight HA.

Abstract
Seven Delta-disaccharide standards from heparan sulfate/heparin (HS/H) and nine Delta-disaccharide standards from chondroitin/dermatan sulfate (CS/DS) and hyaluronic acid (HA) were derivatized with the fluorophore 2-aminoacridone (AMAC) and separated in two runs each by reversed-phase HPLC with baseline separation and very short run times. This novel method facilitates the separation of the largest number of Delta-disaccharides from both CS/DS/HA and HS/H with one column and buffer system after fluorophore labeling in two runs at present. For the first time nine glycosaminoglycan (GAG) Delta-disaccharides from CS/DS/HA were separated after fluorophore labeling in one run. The limits of quantification (LOQs) were below 0.2 pmol for CS/DS/HA and HS/H Delta-disaccharides. We demonstrated applicability of our method for biological samples. Furthermore, normal ranges of the GAG Delta-disaccharide compositions from platelets and granulocytes were determined for the first time.

Abstract
Chondroitin sulfate (CS) is a glycosaminoglycan derived from cartilage and commonly used to treat osteoarthritis, psoriasis, and other conditions. The dimethylmethylene blue (DMMB) assay has been used often to measure glycosaminoglycan levels in relatively pure samples. In this study, we verified the accuracy of the DMMB assay in measuring CS levels in unpurified extract from bovine trachea and shark cartilage, despite potential interference from salts, proteins, and DNA. We found that the glycosaminoglycan signal obtained was due to CS and not to other glycosaminoglycan species. This was confirmed using fluorophore-assisted carbohydrate electrophoresis, which also revealed that the majority of the CS was monosulfated at the C4 or C6 position. Finally, we used anion-exchange chromatography to purify the bovine extract and obtained complete recovery of the glycosaminoglycans, with no contaminating protein. The results of this study should be very useful for future purification and analysis of this common supplement.

Abstract
Chondroitin sulfate (CS) is an omnipresent glycosaminoglycan with significant biologic roles. Chondroitin sulfate has not one structure but its polysaccharide backbone is modified to a smaller or higher degree according to the cell, tissue, species localization, and/or physiopathological stimuli. The potential of chondroitin sulfate for the therapy of osteoarthritis has been under investigation in several clinical trials, which have shown that it is safe and well tolerated. However, there are many issues still unresolved, such as the structure-modifying effects of CS in osteoarthritis, symptom-modifying efficacy in certain groups of patients, structure-activity-pharmacokinetic relationships, knowledge of mechanism of action, and better quality control of the preparations. Furthermore, ongoing basic research on its biologic role will probably show other therapeutic applications.

Abstract
Chondroitin sulfate (CS) dermatan sulfate (DS), and CS/DS hybrid chains are biologically active like heparan sulfate, and structurally the most complex species of the glycosaminoglycan family along with heparan sulfate. They exist at the cell surface and extracellular matrix in the form of proteoglycans. They function as regulators of functional proteins such as growth factors, cytokines, chemokines, adhesion molecules, and lipoproteins through interactions with the ligands of these proteins via specific saccharide domains. Structural alterations have been often implicated in pathological conditions, such as cancer and atherosclerosis. Recent microsequencing of CS/DS oligosaccharides that bind growth factors, such as pleiotrophin, and various monoclonal antibodies against CS/DS, have revealed a considerable number of unique oligosaccharide sequences. This review focuses on recent advances in the study of the structure-function relation of CS, DS and their hybrid chains in physiological and pathological conditions.

Abstract
Exogenous administration of chondroitin sulfate (CS) is widely practiced for the treatment of osteoarthritis, although the efficacy of this treatment has not been completely established by clinical studies. A reason for the inconsistency of the results may be the quality of the CS preparations, which are commercially available as dietary supplements. In this article, we describe the development of a new method of capillary electrophoresis (CE) for the quantification of CS concentrations, screening for other glycosaminoglycan or DNA impurities and determination of hyaluronan impurities in CS raw materials, tablets, hard capsules, and liquid formulations. Analysis is performed within 12 min in bare fused silica capillaries using reversed polarity and an operating phosphate buffer of low pH. The method has high sensitivity (lower limit of quantitation [LLOQ] values of 30.0 microg/ml for CS and 5.0 microg/ml for hyaluronan), high precision, and accuracy. Analysis of 11 commercially available products showed the presence of hyaluronan impurities in most of them (up to 1.5%). CE analysis of the samples after treatment with chondroitinase ABC and ACII, which depolymerize the chains to unsaturated disaccharides, with a previously described method (Karamanos et al., J. Chromatogr. A 696 (1995) 295-305) confirmed the results of hyaluronan determination and showed that the structural characteristics (i.e., disaccharide composition) of CS are very different, showing the different species or tissue origin and possibly affecting the therapeutic outcome.

Abstract
A novel in-gel endoglycosidase technique to study oligosaccharides with graphitized carbon LC-MS has revealed differences in the sulfation profile between the linkage and repeat regions of chondroitin sulfate on aggrecan. Bovine articular cartilage aggrecan was isolated in a composite agarose PAGE gel or diluted in ammonium acetate buffer and was digested overnight with chondroitinase ABC. Including a chemical release/reduction protocol after digestion, we could separate and detect three differentially sulfated chondroitin sulfate disaccharides of the repeat region (DeltaUA1-3GalNAc0/4/6S-ol) from the three differentially sulfated linkage region hexasaccharides (DeltaUA1-3GalNAc0/4/6Sbeta1-4GlcAbeta1-3Galbeta1-3Galbeta1-4Xylitol). Graphitized carbon LC-MS in the negative ion mode was able to resolve isomeric disaccharides and linkage region hexasaccharides. Specific MS2 and MS3 enabled us to confirm the sulfate location on all oligosaccharides by comparing their fragmentation with sulfated disaccharide standards. The presence of unsulfated, 6-sulfated, and 4-sulfated linkage regions was correlated with positive Western blot staining with the respective CS linkage region neoepitope antibodies (1B5, 3B3, 2B6) on digested aggrecan. Our strategy of examining linkage region and repeat region profiles is applicable to screening GAGs from various biological samples in order to detect differences between normal and disease states.

Abstract
Ultraviolet matrix-assisted laser desorption/ionization mass spectrometric (UV-MALDI-MS) analysis of highly acidic, thermally labile species such as glycosaminoglycan-derived oligosaccharides is complicated by their poor ionization efficiency and tendency to fragment through the loss of sulfo groups. We have utilized a systematic approach to evaluate the effect of alkali metal counterions on the degree of fragmentation through SO3 loss from a highly sulfated model compound, sucrose octasulfate (SOS). The lithium, sodium, potassium, rubidium, and cesium salts of SOS were analyzed by UV-MALDI-time-of-flight (TOF)MS using an ionic liquid matrix, bis-1,1,3,3-tetramethylguanidinium alpha-cyano-4-hydroxycinnamate. The positive-ion and negative-ion MALDI mass spectra of five alkali metal salts of SOS were compared in terms of the degree of analyte fragmentation through the SO3 loss and the absolute intensity of a molecular ion signal. Experimental results demonstrate that the lithium, sodium, and potassium salts of SOS undergo some degree of fragmentation through the loss of SO3, whereas the fragmentation through the loss of SO3 in the rubidium and cesium salts of SOS is suppressed. A high detection sensitivity associated with the stability of sulfate half-esters was achieved for the cesium salt of SOS using positive-ion detection. Finally, the cesium salt of chondroitin sulfate A disaccharide was successfully analyzed using UV-MALDI-TOFMS.
