Carbohydr Res 2023; 529:108832. [PMID: 37192581 DOI: 10.1016/j.carres.2023.108832] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 05/01/2023] [Accepted: 05/03/2023] [Indexed: 05/18/2023]
Abstract
Heparin-like sulfated polysaccharide, acharan sulfate, was purified from the mucus of an African giant snail with unique sulfated glycosaminoglycans (GAGs). This study reported on finding novel and safe heparin resources from Achatina fulica for further use as well as easy isolation and purification of the active fraction from the initial raw material. Its structure was characterised by a strong-anion exchange combined with high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR) spectroscopy. The results indicated that the potential acharan sulfate fraction is a glycosaminoglycan composed of several repeating disaccharide units, namely, of →4)-α-IdoA(2S)(1→4)-α-GlcNAc/GlcNAc(6S)/GlcNSO3(6S)(1→, and hence, presents heterogeneity regarding negative net charge density. Furthermore, the heparinase digests inhibit the binding of SARS-CoV-2 spike protein to the ACE2 receptor. In summary, the acharan sulfate presented in this work has shown its great potential for application in the preparation of sulfated polysaccharides as an alternative to heparin with important biological activity.

Abstract
Glycosaminoglycans (GAGs) are heterogeneous acidic polysaccharides involved in a range of biological functions. They have a significant influence on the regulation of cellular processes and the development of various diseases and infections. To fully understand the functional roles that GAGs play in mammalian systems, including disease processes, it is essential to understand their structural features. Despite having a linear structure and a repetitive disaccharide backbone, their structural analysis is challenging and requires elaborate preparative and analytical techniques. In particular, the extent to which GAGs are sulfated, as well as variation in sulfate position across the entire oligosaccharide or on individual monosaccharides, represents a major obstacle. Here, we summarize the current state-of-the-art methodologies used for GAG sample preparation and analysis, discussing in detail liquid chromatograpy and mass spectrometry-based approaches, including advanced ion activation methods, ion mobility separations and infrared action spectroscopy of mass-selected species.

Abstract
The tumor microenvironment (TME) is composed of cancerous, non-cancerous, stromal, and immune cells that are surrounded by the components of the extracellular matrix (ECM). Glycosaminoglycans (GAGs), natural biomacromolecules, essential ECM, and cell membrane components are extensively altered in cancer tissues. During disease progression, the GAG fine structure changes in a manner associated with disease evolution. Thus, changes in the GAG sulfation pattern are immediately correlated to malignant transformation. Their molecular weight, distribution, composition, and fine modifications, including sulfation, exhibit distinct alterations during cancer development. GAGs and GAG-based molecules, due to their unique properties, are suggested as promising effectors for anticancer therapy. Considering their participation in tumorigenesis, their utilization in drug development has been the focus of both industry and academic research efforts. These efforts have been developing in two main directions; (i) utilizing GAGs as targets of therapeutic strategies and (ii) employing GAGs specificity and excellent physicochemical properties for targeted delivery of cancer therapeutics. This review will comprehensively discuss recent developments and the broad potential of GAG utilization for cancer therapy.

Abstract
The general function of anticoagulants is to prevent blood clotting and growing of the existing clots in blood vessels. In recent years, there has been a significant improvement in developing methods of prevention as well as pharmacologic and surgical treatment of thrombosis. For over the last two decades, low molecular weight heparins (LMWHs) have found their application in the antithrombotic diseases treatment. These types of drugs are widely used in clinical therapy. Despite the biological and medical importance of LMWHs, they have not been completely characterized in terms of their chemical structure. Due to both, the structural complexity of these anticoagulants and the presence of impurities, their structural characterization requires the employment of advanced analytical techniques. Since separation techniques play the key role in these endeavors, this review will focus on the presentation of recent developments in the separation of LMWH anticoagulants.

Abstract
The antithrombin III (ATIII)-binding site, which contains a special 3-O-sulfated, N-sulfated glucosamine residue with or without 6-O-sulfation, is mainly responsible for the anticoagulant activity of heparin. Undergoing the chemical depolymerization process, the preservation of the ATIII-binding site in low molecular weight heparins (LMWHs) are varied leading to the fluctuation of the anticoagulant activity. Herein we report a capillary electrophoresis (CE) method in combination with heparinase digestion and affinity chromatography for the measurement of molar percentage of ATIII-binding site of LMWHs. After exhaustively digesting LMWHs with the mixture of heparinase I, II and III, almost all the resulting oligosaccharide building blocks, including the three 3-O-sulfated tetrasaccharides derived from the ATIII-binding site, were resolved by CE separation. The peak area of each building block permits quantification of the molar percentage of the ATIII-binding site. The peaks corresponding to the 3-O-sulfated tetrasaccharides were assigned based on the linear relationship between the electrophoretic mobilities of the oligosaccharides and their charge to mass ratios. The peak assignment was further confirmed by analysis of the high ATIII affinity fractions, which contains much high 3-O-sulfated tetrasaccharides. With the method, the molar percentage of the ATIII-binding site of enoxaparin from different batches and different manufactures were measured and compared. It was demonstrated that the CE method provides more precise data for assessing the anti-FXa activity than that of the biochemical assay method.

Abstract
Glycosaminoglycans are integral part of the dynamic extracellular matrix (ECM) network that control crucial biochemical and biomechanical signals required for tissue morphogenesis, differentiation, homeostasis and cancer development. Breast cancer cells communicate with stromal ones to modulate ECM mainly through release of soluble effectors during cancer progression. The intracellular cross-talk between cell surface receptors and estrogen receptors is important for the regulation of breast cancer cell properties and production of ECM molecules. In turn, reorganized ECM-cell surface interface modulates signaling cascades, which regulate almost all aspects of breast cell behavior. Heparan sulfate chains present on cell surface and matrix proteoglycans are involved in regulation of breast cancer functions since they are capable of binding numerous matrix molecules, growth factors and inflammatory mediators thus modulating their signaling. In addition to its anticoagulant activity, there is accumulating evidence highlighting various anticancer activities of heparin and nano-heparin derivatives in numerous types of cancer. Importantly, heparin derivatives significantly reduce breast cancer cell proliferation and metastasis in vitro and in vivo models as well as regulates the expression profile of major ECM macromolecules, providing strong evidence for therapeutic targeting. Nano-formulations of the glycosaminoglycan heparin are possibly novel tools for targeting tumor microenvironment. In this review, the role of heparan sulfate/heparin and its nano-formulations in breast cancer biology are presented and discussed in terms of future pharmacological targeting.

Abstract
Heparan sulfate (HS), a glycosaminoglycan present on the surface of cells, has been postulated to have important roles in driving both normal and pathological physiologies. The chemical structure and sulfation pattern (domain structure) of HS is believed to determine its biological function, to vary across tissue types, and to be modified in the context of disease. Characterization of HS requires isolation and purification of cell surface HS as a complex mixture. This process may introduce additional chemical modification of the native residues. In this study, we describe an approach towards thorough characterization of bovine kidney heparan sulfate (BKHS) that utilizes a variety of orthogonal analytical techniques (e.g. NMR, IP-RPHPLC, LC-MS). These techniques are applied to characterize this mixture at various levels including composition, fragment level, and overall chain properties. The combination of these techniques in many instances provides orthogonal views into the fine structure of HS, and in other instances provides overlapping / confirmatory information from different perspectives. Specifically, this approach enables quantitative determination of natural and modified saccharide residues in the HS chains, and identifies unusual structures. Analysis of partially digested HS chains allows for a better understanding of the domain structures within this mixture, and yields specific insights into the non-reducing end and reducing end structures of the chains. This approach outlines a useful framework that can be applied to elucidate HS structure and thereby provides means to advance understanding of its biological role and potential involvement in disease progression. In addition, the techniques described here can be applied to characterization of heparin from different sources.

Abstract
Soft tissue sarcomas are rare, heterogeneous tumors of mesenchymal origin with an aggressive behavior. Heparin is a mixture of heavily sulfated, linear glycosaminoglycan (GAG) chains, which participate in the regulation of various cell biological functions. Heparin is considered to have significant anticancer capabilities, although the mechanisms involved have not been fully defined. In the present study, the effects of unfractionated heparin (UFH) and low-molecular-weight heparin (LMWH) on B6FS fibrosarcoma cell motility were examined. Both preparations of heparin were shown to both enhance B6FS cell adhesion (p<0.01 and p<0.05), and migration (p<0.05), the maximal effect being evident at the concentration of 10 µg/ml. The utilization of FAK-deficient cells demonstrated that the participation of FAK was obligatory for heparin-dependent fibrosarcoma cell adhesion (p<0.05). The results of confocal microscopy indicated that heparin was taken up by the B6FS cells, and that UFH and LMWH induced F-actin polymerization. Heparitinase digestion demonstrated that the endogenous heparan sulfate (HS) chains did not affect the motility of the B6FS cells (p>0.05, not significant). In conclusion, both UFH and LMWH, through a FAK/actin cytoskeleton axis, promoted the adhesion and migration of B6FS fibrosarcoma cells. Thus, our findings indicate that the responsiveness of fibrosarcoma cells to the exogenous heparin/HS content of the cancer microenvironment may play a role in their ability to become mobile and metastasize.

Abstract
The depolymerisation of porcine mucosal heparan sulfate under the action of heparin lyases and analysis by size-exclusion chromatography (SEC) is described. Heparan sulfate treated to enzymic bond scission producing a Δ4,5 double-bond and quantified by SEC with ultraviolet-visible (UV) spectroscopic detection (230nm) indicated that the majority of the biopolymer (>85%) was reduced to disaccharides (degree of polymerisation (DP)=2). However, analysis of the SEC eluant using refractive index (RI), which reflects the mass contribution of the oligosaccharides rather than the molar response of a UV chromophore, indicated that a considerable proportion of the digested HS, up to 43%, was present with DP >2. This was supported by a mass balance analysis. These results contradict the accepted literature where "complete digestion" is routinely reported. Herein we report on the composition and methodology utilised to ascertain the extent of depolymerization and disaccharide composition of this important biopolymer.

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
Heparin has been the most commonly used anticoagulant drug for nearly a century. The drug heparin is generally categorized into three forms according to its molecular weight: unfractionated (UF, average molecular weight 13 000), low molecular weight (average molecular weight 5000) and ultra-low-molecular-weight heparin (ULMWH, average molecular weight 2000). An overdose of heparin may lead to very dangerous bleeding in patients. Protamine sulfate may be administered as an antidote to reverse heparin's anticoagulant effect. However, there is no effective antidote for ULMWH. In the current study, we examine the use of human N-acetylglucosamine 6-sulfatase (NG6S), expressed in Chinese hamster ovary cells, as a reversal agent for ULMWH. NG6S removes a single 6-O-sulfo group at the non-reducing end of the ULMWH Arixtra(®) (fondaparinux), effectively removing its ability to bind to antithrombin and preventing its inhibition of coagulation factor Xa. These results pave the way to developing human NG6S as an antidote for neutralizing the anticoagulant activity of ULMWHs.

Abstract
Glycosaminoglycans (GAGs) are a class of biopolymers that include chondrotin sulfate, dermatan sulfate, keratan sulfate, hyaluronic acid, heparin, and heparan sulfate. The GAGs are linear polysaccharides that are microheterogeneous in composition and polydisperse in size. Because they have the most complex structures, this article is aimed at describing a step-by-step procedure for processing and analyzing heparin and heparan sulfate-derived oligosaccharides, although the basic protocols and procedures apply equally well to other members of the GAG family. The methods described in this manuscript include the preparation of oligosaccharides through enzymatic depolymerization, size fractionation by preparative scale size-exclusion chromatography (SEC), and disaccharide isomer analysis by reverse-phase ion-pair high-performance liquid chromatography (RPIP-HPLC) and capillary electrophoresis (CE).

Abstract
Lowering the efficacious dose of bone morphogenetic protein-2 (BMP-2) for the repair of critical-sized bone defects is highly desirable, as supra-physiological amounts of BMP-2 have an increased risk of side effects and a greater economic burden for the healthcare system. To address this need, we explored the use of heparan sulfate (HS), a structural analog of heparin, to enhance BMP-2 activity. We demonstrate that HS isolated from a bone marrow stromal cell line (HS-5) and heparin each enhances BMP-2-induced osteogenesis in C2C12 myoblasts through increased ALP activity and osteocalcin mRNA expression. Commercially available HS variants from porcine kidney and bovine lung do not generate effects as great as HS5. Heparin and HS5 influence BMP-2 activity by (i) prolonging BMP-2 half-life, (ii) reducing interactions between BMP-2 with its antagonist noggin, and (iii) modulating BMP2 distribution on the cell surface. Importantly, long-term supplementation of HS5 but not heparin greatly enhances BMP-2-induced bone formation in vitro and in vivo. These results show that bone marrow-derived HS effectively supports bone formation, and suggest its applicability in bone repair by selectively facilitating the delivery and bioavailability of BMP-2.

Abstract
The structural microheterogeneity of heparin and heparan sulfate is one of the major reasons for the multifunctionality exhibited by this class of molecules. In a physiological context, these molecules primarily exert their effects extracellularly by mediating key processes of cellular cross-talk and signaling leading to the modulation of a number of different biological activities including development, cell proliferation, and inflammation. This structural diversity is biosynthetically imprinted in a nontemplate-driven manner and may also be dynamically remodeled as cellular function changes. Understanding the structural information encoded in these molecules forms the basis for attempting to understand the complex biology they mediate. This chapter provides an overview of the origin of the structural microheterogeneity observed in heparin and heparan sulfate, and the orthogonal analytical methodologies that are required to help decipher this information.

Abstract
Synthesis of amphiphilic oligosaccharides is problematic because traditional methods for separating and purifying oligosaccharides, including sulfated oligosaccharides, are generally not applicable to working with amphiphilic sugars. We report here RPIP-LC and LC-MS methods that enable the synthesis, separation, and characterization of amphiphilic N-arylacyl O-sulfonated aminoglycosides, which are being pursued as small-molecule glycosaminoglycan mimics. The methods described in this work for separating and characterizing these amphiphilic saccharides are further applied to a number of uses: monitoring the progression of sulfonation reactions with analytical RP-HPLC, characterizing sulfate content for individual molecules with ESI-MS, determining the degree of sulfation for products having mixed degrees of sulfation with HPLC and LC-MS, and purifying products with benchtop C18 column chromatography. We believe that the methods described here will be broadly applicable to enabling the synthesis, separation, and characterization of amphiphilic, sulfated, and phosphorylated oligosaccharides and other types of molecules substituted to varying degrees with both anionic and hydrophobic groups.

Abstract
Reverse-phase ion-pair high-performance liquid chromatography (RPIP-HPLC) is an increasingly popular chromatographic technique for the separation of charged compounds, including oligosaccharides derived from the glycosaminoglycans (GAGs) heparin and heparan sulfate (HS). This family of heparin disaccharides has been shown to be useful compounds to probe the details of the RPIP-HPLC separation mechanism, the aspects of which are still being debated. In this manuscript, the effects of ion-pairing reagent (IPR) concentration, counterion, and mobile phase pH on the quality of the RPIP-UPLC separation were examined with particular emphasis on how these factors impact the separation of the disaccharide anomers. These results highlight the role of the IPR counterion and demonstrate that the resolution of the disaccharide anomers can be minimized by conducting the separation at low pH, simplifying chromatographic analysis and improving resolution. The results presented herein can also provide insights into strategies for developing more sensitive and efficient reverse-phase separations for other charged analytes including larger GAG oligosaccharides.

Abstract
Although heparin is an important and widely prescribed pharmaceutical anticoagulant, its high degree of sequence microheterogeneity and size polydispersity make molecular-level characterization challenging. Unlike nucleic acids and proteins that are biosynthesized through template-driven assembly processes, heparin and the related glycosaminoglycan heparan sulfate are actively remodeled during biosynthesis through a series of enzymatic reactions that lead to variable levels of O- and N-sulfonation and uronic acid epimers. As summarized in this review, heparin sequence information is determined through a bottom-up approach that relies on depolymerization reactions, size- and charge-based separations, and sensitive mass spectrometric and nuclear magnetic resonance experiments to determine the structural identity of component oligosaccharides. The structure-elucidation process, along with its challenges and opportunities for future analytical improvements, is reviewed and illustrated for a heparin-derived hexasaccharide.

Abstract
The elucidation of the structure of glycosaminoglycan has proven to be challenging for analytical chemists. Molecules of glycosaminoglycan have a high negative charge and are polydisperse and microheterogeneous, thus requiring the application of multiple analytical techniques and methods. Heparin and heparan sulfate are the most structurally complex of the glycosaminoglycans and are widely distributed in nature. They play critical roles in physiological and pathophysiological processes through their interaction with heparin-binding proteins. Moreover, heparin and low-molecular weight heparin are currently used as pharmaceutical drugs to control blood coagulation. In 2008, the health crisis resulting from the contamination of pharmaceutical heparin led to considerable attention regarding their analysis and structural characterization. Modern analytical techniques, including high-performance liquid chromatography, capillary electrophoresis, mass spectrometry, and nuclear magnetic resonance spectroscopy, played critical roles in this effort. A successful combination of separation and spectral techniques will clearly provide a critical advantage in the future analysis of heparin and heparan sulfate. This review focuses on recent efforts to develop hyphenated techniques for the analysis of heparin and heparan sulfate.

Abstract
This review discusses recent developments in analytical methods available for the sensitive separation, detection and structural characterization of heparin contaminants. The adulteration of raw heparin with oversulfated chondroitin sulfate (OSCS) in 2007–2008 spawned a global crisis resulting in extensive revisions to the pharmacopeia monographs on heparin and prompting the FDA to recommend the development of additional physicochemical methods for the analysis of heparin purity. The analytical chemistry community quickly responded to this challenge, developing a wide variety of innovative approaches, several of which are reported in this special issue. This review provides an overview of methods of heparin isolation and digestion, discusses known heparin contaminants, including OSCS, and summarizes recent publications on heparin impurity analysis using sensors, near-IR, Raman, and NMR spectroscopy, as well as electrophoretic and chromatographic separations.

Abstract
Chondroitin sulfate (CS) has an important role in cell division, in the central nervous system, and in joint-related pathologies such as osteoarthritis. Due to the complex chemical structure and biological importance of CS, simple, sensitive, high resolution, and robust analytical methods are needed for the analysis of CS disaccharides and oligosaccharides. An ion-pairing, reversed-phase, ultraperformance liquid chromatography (IPRP-UPLC) separation, coupled to electrospray ionization mass spectrometry with an ion trap mass analyzer, was applied for the analyses of CS-derived disaccharides. UPLC separation technology uses small particle diameter, short column length, and elevated column temperature to obtain high resolution and sensitivity. Hexylamine (15 mM) was selected as the optimal ion-pairing reagent.

Abstract
Current chromatographic and mass spectrometric techniques have limitations for analyzing heparin and heparin oligomers due to their high polarity, structural diversity, and sulfate lability. A rapid method for the analysis of heparin oligosaccharides was developed using ion-pair reversed-phase ultraperformance liquid chromatography coupled with electrospray quadruple time-of-flight mass spectrometry (IPRP-UPLC ESI Q-TOF MS). The method utilizes an optimized buffer system containing a linear pentylamine and a unique additive, 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), to achieve highly efficient separation together with enhanced mass response of heparin oligosaccharides. Analyses of a heparin oligosaccharide test mixture, dp6 through dp22, reveal that the chromatographic conditions enable baseline resolution of isomeric heparin oligosaccharides (dp6) and produce intact molecular ions with no sulfate losses during mass spectrometric analysis. In addition, the described conditions are amenable to the detection of heparin oligosaccharides in positive ion mode, yield stronger positive ion signals for corresponding oligosaccharides compared to the negative ion mode, and allow identification of structural isomers by an MS/MS approach. Because sensitive detection of oligosaccharides is also achieved with ultraviolet (UV) detection, the method utilizes a dual detection scheme (UV and MS in series) along with IPRP UPLC to simultaneously obtain quantification (UV) and characterization (MS) data for heparin oligosaccharides. The broad potential of this new method is further demonstrated for the analysis of a low-molecular-weight heparin (LMWH) preparation from porcine heparin. This approach will be of particular utility for profiling the molecular entities of heparin materials, as well as for structural variability comparison for samples from various sources.

Abstract
This work describes improved workup and instrumental conditions to enable robust, sensitive glycosaminoglycan (GAG) disaccharide analysis from complex biological samples. In the process of applying CE with LIF to GAG disaccharide analysis in biological samples, we have made improvements to existing methods. These include (i) optimization of reductive amination conditions, (ii) improvement in sensitivity through the use of a cellulose cleanup procedure for the derivatization, and (iii) optimization of separation conditions for robustness and reproducibility. The improved method enables analysis of disaccharide quantities as low as 1 pmol prior to derivatization. Biological GAG samples were exhaustively digested using lyase enzymes, the disaccharide products and standards were derivatized with the fluorophore 2-aminoacridone and subjected to reversed polarity CE-LIF detection. These conditions resolved all known chondroitin sulfate (CS) disaccharides or 11 of 12 standard heparin/heparan sulfate disaccharides, using 50 mM phosphate buffer, pH 3.5, and reversed polarity at 30 kV with 0.3 psi pressure. Relative standard deviation in migration times of CS ranged from 0.1 to 2.0% over 60 days, and the relative standard deviations of peak areas were less than 3.2%, suggesting that the method is reproducible and precise. The CS disaccharide compositions are similar to those obtained by our group using tandem MS. The reversed polarity CE-LIF disaccharide analysis protocol yields baseline resolution and quantification of heparin/heparan sulfate and CS/dermatan sulfate disaccharides from both standard preparations and biologically relevant proteoglycan samples. The improved CE-LIF method enables disaccharide quantification of biologically relevant proteoglycans from small samples of intact tissue.

Abstract
Heparin (HE) and heparan sulfated glycosaminoglycans are well-known mediators of tissue development, maintenance and functions; the activities of these polysaccharides are depending mainly on their sulfate substitutions. The HE structure is also a very important feature in antithrombotic drug development, since the antithrombin binding site is composed by sequences of a specific sulfation pattern. The analysis of disaccharide composition is then a fundamental point of all the studies regarding HE/heparan sulfate glycosaminoglycan (and thereby proteoglycan) functions. The present work describes two analytical methods to quantify the disaccharides constituting HE and heparan sulfate chains. The use of PAGE of fluorophore-labeled saccharides and HPLC coupled with a fluorescence detector allowed in one run the identification of 90-95% of HE disaccharides and 74-100% of rat kidney purified heparan sulfate. Moreover, the protocol here reported avoid the N-sulfation disaccharides degradation, which may affect N-sulfated/N-acetylated disaccharides ratio evaluation. These methods could be also very important in clinical treatments since they are useful for monitoring the availability kinetics of antithrombotic drugs, such as low-molecular-weight HEs.

Abstract
Elucidation of the relationship between the structure and biological function of the glycosaminoglycans (GAGs) heparin and heparan sulfate (HS) presents an important analytical challenge mainly due to the difficulty in determining their fine structure. Heparin and HS are responsible for mediation of a wide range of biological actions through specific binding to a variety of proteins including those involved in blood coagulation, cell proliferation, differentiation and adhesion, and host-pathogen interactions. Therefore, there is a growing interest in characterizing the microstructure of heparin and HS and in elucidating the molecular level details of their interaction with peptides and proteins. This review discusses recent developments in the analytical methods used for sensitive separation, detection, and structural characterization of heparin and HS. A brief discussion of the analysis of contaminants in pharmaceutical heparin is also presented.

Abstract
Heparin and heparan sulfate (HS) are important pharmaceutical targets because they bind a large number of proteins, including growth factors and cytokines, mediating many biological processes. Because of their biological significance and complexity, there is a need for development of rapid and sensitive analytical techniques for the characterization and compositional analysis of heparin and HS at the disaccharide level, as well as for the structure elucidation of larger glycosaminoglycan (GAG) sequences important for protein binding. In this work, we present a rapid method for analysis of disaccharide composition using reversed-phase ion-pairing ultraperformance liquid chromatography coupled with electrospray time-of-flight mass spectrometry ((RPIP)-UPLC-MS). Heparin disaccharide standards were eluted in less than 5 min. The method was used to determine the constituents of GAGs from unfractionated heparin/HS from various bovine and porcine tissues, and the results were compared with literature values.

Abstract
Glycosaminoglycans (GAGs) are important in a number of biological processes and are structurally altered in many pathological conditions. The complete determination of GAG primary structures has been hampered by the lack of sensitive and specific analytical techniques. Nuclear magnetic resonance spectroscopy (NMR) is a powerful tool for GAG structure elucidation despite its relatively poor limits of detection. Solenoidal microcoils have greatly enhanced the mass limits of detection of NMR, enabling the on-line coupling of microseparation and concentration techniques such as capillary isotachophoresis (cITP), which can separate and concentrate analytes by 2-3 orders of magnitude. We have successfully used cITP coupled with on-line NMR detection to separate and concentrate nanomole quantities of heparin oligosaccharides. This sensitive on-line measurement approach has the potential to provide new insights into the relationships between biological function and GAG microstructures.

Abstract
We examined the effect of dietary Mn on the composition and structure of heparan sulfate (HS) glycosaminoglycans (GAGs) of rat aorta. Animals were randomly assigned to either a Mn deficient (MnD), adequate (MnA) or supplemented (MnS) diet (Mn<1, 10-15 and 45-50 ppm, respectively). After 15 weeks, aortic tissue GAGs were isolated with papain digestion, alkaline borohydride treatment and anion-exchange chromatography. Cellulose acetate electrophoresis and treatment of the fractions with specific lyases revealed the presence of three GAG populations, i.e. hyaluronan (HA), heparan sulfate (HS) and galactosaminoglycans (GalAGs). Disaccharide composition of the HS fractions was determined by HPCE following treatment with heparin lyases I, II and III. In MnS aortas we observed increased concentration of total GalAGs and decreased concentration of HS and HA, when compared to MnA aortas. Aortas from MnD and MnA rats appeared to have similar distribution of individual GAGs. Heparan sulfate chains of MnS aortas contained higher (41%) concentration of non-sulfated units compared to MnA ones. Variable amounts of trisulfated and disulfated units were found only in MnD and MnA groups but not in MnS. Our results demonstrate that HS biosynthesis in the rat aorta undergoes marked structural modifications that depend upon dietary Mn intake. The reduced expression and undersulfation of HSPGs with Mn supplementation might indicate a reduced ability of vascular cells to interact with biologically active molecules such as growth factors. Alterations in cell-membrane binding ability to a variety of extracellular ligands might affect signal-transduction pathways and arterial functional properties.

Abstract
A method has been developed for the identification and quantitative determination of sulphated disaccharides derived from chondroitin sulphate (CS) and dermatan sulphate (DS) chains attached to proteoglycans (PGs). After digestion with Chondroitinase ABC, the pool of disaccharides can be directly separated by liquid chromatography on a porous graphitized carbon (PGC) column and identified by on-line electrospray mass spectrometry under negative ionization conditions. The relative intensities of the fragment ions obtained by MS/MS allow to distinguish the sulphate position. Calibration with standard disaccharides allows the quantification of the different isomers. The method showed good repeatability in terms of relative standard deviation (RSD < 2%) and linearity between 0.5 and 50 ng (total injected amount) for both 4- and 6-sulphated disaccharides. The limit of detection achieved in full scan mode was 0.1 ng. The methodology was applied to different types of biological samples obtained from patients suffering from chronic lung inflammation such as: lung tissue, bronchoalveolar lavage fluid (BALF), induced sputum and urine.

Abstract
An important class of carbohydrates studied within the field of glycobiology, heparin and heparan sulfate (HS) have been implicated in a diverse array of biological functions. Changes in their sulfation pattern and domain organization have been associated with different pathological situations such as viral infectivity, tumor growth, and metastasis. To obtain structural information about these biomolecules, and the modifications they may undergo during different stages of cell growth and development, a mass spectrometry-based method was developed and used to obtain unambiguous structural information on the glycosaminoglycans (GAGs) that comprise heparin/HS. The method was applied to assay for the heparin substrate specificity of a newly discovered human extracellular endosulfatase, HSulf-2, which has been implicated in tumorigenesis. This new protocol incorporates 12 known heparin disaccharides, including three sets of isomers. A unique response factor (R) is determined for each disaccharide, whereas a multiplexed and data processing method is incorporated for faster data acquisition and quantification purposes. Proof of principle was performed by using various heparin/HS samples isolated from bovine and porcine tissues.
