Abstract
To evaluate a new approach to Mucopolysaccharidosis type IIIA (MPS-IIIA), work was initiated on primary fibroblasts from a well-known mouse model in which sulfamidase deficiency correlates with the accumulation of heparan sulfate - the hallmark of this disease. Once the culture of fibroblasts was established, we observed continuous proliferation with a rapid growth rate, loss of contact inhibition and late passage stability, corresponding to a spontaneously immortalized cell line. The presence of the single point D31N mutation was verified and both rapid and abundant intracellular accumulation of low molecular weight HS was observed, confirming both genotype and phenotype. This cell line is a potential in vitro model system for future studies of MPS-IIIA prior to employing animal models.

Abstract
Background Allogeneic stem cell transplantation (SCT) enhances coagulation via endothelial perturbation and inflammation. Role of natural anticoagulants in interactions between coagulation and inflammation as well as in acute graft-versus-host disease (GVHD) are not well known. The purpose of this study was to define changes in natural anticoagulants over time in association with GVHD. Patients and methods This prospective study included 30 patients who received grafts from siblings (n = 19) or unrelated donors (n = 11). Eight patients developed GVHD. Standard clinical assays were applied to measure natural anticoagulants, represented by protein C (PC), antithrombin (AT), protein S (PS), complex of activated PC with its inhibitor (APC-PCI) and by markers of endothelial activation: Factor VIII coagulant activity (FVIII:C) and soluble thrombomodulin (s-TM) at 6–8 time points over three months. Results Overall, PC, AT and FVIII:C increased in parallel after engraftment. Significant correlations between PC and FVIII:C (r = 0.64–0.82, p<0.001) and between PC and AT (r = 0.62–0.81, p<0.05) were observed at each time point. Patients with GVHD had 21% lower PC during conditioning therapy and 55% lower APC-PCI early after transplantation, as well as 37% higher values of s-TM after engraftment. The GVHD group had also increases of PC (24%), FVIII: C (28%) and AT (16%) three months after transplantation. Conclusion The coordinated activation of natural anticoagulants in our longitudinal study indicates the sustained ability of adaptation to endothelial and inflammatory activation during allogenic SCT treatment. The suboptimal control of coagulation by natural anticoagulants at early stage of SCT may contribute to onset of GVHD.

Abstract
Anticoagulant heparan sulfate proteoglycans bind and activate antithrombin by virtue of a specific 3-O-sulfated pentasaccharide. They not only occur in the vascular wall but also in extravascular tissues, such as the ovary, where their functions remain unknown. The rupture of the ovarian follicle at ovulation is one of the most striking examples of tissue remodeling in adult mammals. It involves tightly controlled inflammation, proteolysis, and fibrin deposition. We hypothesized that ovarian heparan sulfates may modulate these processes through interactions with effector proteins. Our previous work has shown that anticoagulant heparan sulfates are synthesized by rodent ovarian granulosa cells, and we now have set out to characterize heparan sulfates from human follicular fluid. Here we report the first anticoagulant heparan sulfate purified from a natural human extravascular source. Heparan sulfate chains were fractionated according to their affinity for antithrombin, and their structure was analyzed by 1H NMR and MS/MS. We find that human follicular fluid is a rich source of anticoagulant heparan sulfate, comprising 50.4% of total heparan sulfate. These antithrombin-binding chains contain more than 6% 3-O-sulfated glucosamine residues, convey an anticoagulant activity of 2.5 IU/ml to human follicular fluid, and have an anti-Factor Xa specific activity of 167 IU/mg. The heparan sulfate chains that do not bind antithrombin surprisingly exhibit an extremely high content in 3-O-sulfated glucosamine residues, which suggest that they may exhibit biological activities through interactions with other proteins.

Abstract
Endothelial cell production of anticoagulant heparan sulfate (HS(act)) is controlled by the Hs3st1 gene, which encodes the rate-limiting enzyme heparan sulfate 3-O-sulfotransferase-1 (3-OST-1). In vitro, HS(act) dramatically enhances the neutralization of coagulation proteases by antithrombin. The in vivo role of HS(act) was evaluated by generating Hs3st1(-/-) knockout mice. Hs3st1(-/-) animals were devoid of 3-OST-1 enzyme activity in plasma and tissue extracts. Nulls showed dramatic reductions in tissue levels of HS(act) but maintained wild-type levels of tissue fibrin accumulation under both normoxic and hypoxic conditions. Given that vascular HS(act) predominantly occurs in the subendothelial matrix, mice were subjected to a carotid artery injury assay in which ferric chloride administration induces de-endothelialization and occlusive thrombosis. Hs3st1(-/-) and Hs3st1(+/+) mice yielded indistinguishable occlusion times and comparable levels of thrombin.antithrombin complexes. Thus, Hs3st1(-/-) mice did not show an obvious procoagulant phenotype. Instead, Hs3st1(-/-) mice exhibited genetic background-specific lethality and intrauterine growth retardation, without evidence of a gross coagulopathy. Our results demonstrate that the 3-OST-1 enzyme produces the majority of tissue HS(act). Surprisingly, this bulk of HS(act) is not essential for normal hemostasis in mice. Instead, 3-OST-1-deficient mice exhibited unanticipated phenotypes suggesting that HS(act) or additional 3-OST-1-derived structures may serve alternate biologic roles.

Abstract
During the reproductive cycle, ovarian follicles undergo major tissue-remodeling involving vascular changes and proteolysis. Anticoagulant heparan sulfate proteoglycans (aHSPGs) are expressed by granulosa cells during the development of the ovarian follicle. The function of aHSPGs in the ovary is unknown, but they might be involved in proteolysis control through binding and activation of serine protease inhibitors. To identify functional interactions between aHSPGs and heparin-binding protease inhibitors in the follicle, we have coordinately localized aHSPGs, antithrombin III, protease nexin-1, and plasminogen activator inhibitor-1 in the rat ovary during natural and gonadotropin-stimulated cycles. Anticoagulant HSPGs were visualized by autoradiography of cryosections incubated with 125I-antithrombin III, and protease inhibitors were assessed by immunohistochemistry and Northern blot hybridization. Anticoagulant HSPGs were expressed in follicles before ovulation, were transiently decreased in postovulatory follicles, and were abundant in the corpus luteum, mainly on capillaries. Anticoagulant HSPGs were colocalized with protease nexin-1 in follicles from the early antral stage until ovulation, with antithrombin III in the preovulatory stage and after ovulation, and with plasminogen activator inhibitor-1 in the corpus luteum. These data demonstrate that aHSPGs are critically expressed in the ovary to interact sequentially with protease nexin-1, antithrombin III, and plasminogen activator inhibitor-1 during the cycle. The specificity of these inhibitors is shifted toward thrombin inhibition in the presence of heparin, suggesting that aHSPGs direct their action to control fibrin deposition in the follicle. The occupation of aHSPGs antithrombin-binding sites by mutant R393C antithrombin III, injected in the ovarian bursa, decreased ovulation efficiency, further supporting the involvement of aHSPGs in the ovulation process.

Abstract
Ovarian granulosa cells synthesize anticoagulant heparan sulfate proteoglycans (aHSPGs), which bind and activate antithrombin III. To determine if aHSPGs could contribute to the control of proteolytic activities involved in follicular development and ovulation, we studied the pattern of expression of these proteoglycans during the ovarian cycle. aHSPGs were localized on cells and tissues by (125)I-labeled antithrombin III binding followed by microscopic autoradiography. Localization of aHSPGs has shown that cultured granulosa cells, hormonally stimulated by gonadotropins to differentiate in vitro, up-regulate their synthesis and release of aHSPGS: In vivo, during gonadotropin-stimulated cycle, aHSPGs are present on granulosa cells of antral follicles and are strongly labeled in preovulatory follicles. These data demonstrate that aHSPG expression in the ovarian follicle is hormonally induced to culminate in preovulatory follicles. Moreover, we have shown that five heparan sulfate core proteins mRNA (perlecan; syndecan-1, -2, and -4; and glypican-1) are synthesized by granulosa cells, providing attachment for anticoagulant heparan sulfate chains on the cell surface and in the extracellular matrix. These core proteins are constantly expressed during the cycle, indicating that modulations of aHSPG levels observed in the ovary are likely controlled at the level of the biosynthesis of anticoagulant heparan sulfate glycosaminoglycan chains. This expression pattern enables aHSPGs to focus serine protease inhibitors in the developing follicle to control proteolysis and fibrin formation at ovulation.

Abstract
Vitronectin (VN) is a high affinity heparin-binding protein. The physiological role of this binding has hitherto received little attention, and its molecular determinants are subject to controversy. In this study, we characterized vitronectin interaction with heparin, heparin analogues, bacterial extracts, and cell surface glycosaminoglycans. As assessed by (i) fluorescence assays, (ii) precipitation with heparin-Sepharose beads, or (iii) Western blotting with antibodies against VN(347-361) (the heparin-binding site), we demonstrate an exposure of the VN heparin-binding site in multimeric but not monomeric vitronectin. Through its heparin-binding site, vitronectin also bound other glycosaminoglycans and Staphylococcus aureus extracts. The kinetics of heparin binding to vitronectin were complex. After a fast association phase (tau = 0.3 s), a slow conversion of an unstable to a stable heparin-vitronectin complex (tau = 180 s) occurred. Heparin binding kinetics and transition to a stable complex were mimicked by VN(347-361), demonstrating that this area is the fully functional heparin-binding site of vitronectin. Multimeric vitronectin bound to endothelial cells. This binding was blocked by soluble heparin and was not observed when endothelial cells were pretreated with glycosaminoglycan-removing enzymes. Glycosaminoglycan-dependent interaction of endothelial cells with multimeric vitronectin might be a relevant mechanism for removal of multimeric vitronectin from plasma. Conversion of an unstable to a stable glycosaminoglycan-vitronectin complex is likely to be relevant for association with endothelial cells under flow conditions.

Abstract
In order to determine the intracellular location of heparan N-deacetylase/N-sulphotransferase, cDNAs encoding human heparan glucosaminyl N-deacetylase/N-sulphotransferase were cloned from human umbilical vein endothelial cells. The deduced amino acid sequence was identical to that of the human heparan N-sulphotransferase cloned previously [Dixon, Loftus, Gladwin, Scambler, Wasmuth and Dixon (1995) Genomics 26, 239-244]. RNA blot analysis indicated that two heparan N-sulphotransferase transcripts of approx. 8.5 and 4 kb were produced in all tissues. Expression was most abundant in heart, liver and pancreas. A cDNA encoding a Flag-tagged human heparan N-sulphotransferase (where Flag is an epitope with the sequence DYKDDDDK) was transfected into mouse LTA cells. Immunofluorescence detection using anti-Flag monoclonal antibodies demonstrated that the enzyme was localized to the trans-Golgi network. A truncated Flag-tagged heparan N-sulphotransferase was also retained in the Golgi, indicating that, as for many other Golgi enzymes, the N-terminal region of heparan N-sulphotransferase is sufficient for retention in the Golgi apparatus.

Abstract
Anticoagulant heparan sulfate proteoglycans endow the vascular endothelium with antithrombotic properties, but their role outside the vascular bed is unknown. Granulosa cells form an avascular compartment in the ovarian follicle, in which a heparin-like activity has been described. At ovulation extravascular coagulation occurs around ovulatory follicles, and after expulsion of the oocyte, a fibrin clot forms in the antral cavity. Granulosa cells synthesize two major heparan sulfate proteoglycans, whose anticoagulant nature has not been investigated. The purpose of this study was to characterize anticoagulant heparan sulfate proteoglycans synthesized by rat ovarian granulosa cells. Affinity purified 35S-labeled anticoagulant heparan sulfate glycosaminoglycans represent 6.5% of the total heparan sulfate synthesized, and they contain 13% 3-O-sulfated disaccharides that are markers of the antithrombin-binding site of heparin. The biological activity of granulosa cell heparan sulfate proteoglycans was demonstrated by their ability to bind antithrombin and to accelerate the formation of thrombin-antithrombin complexes. The impact of hormonal stimulation on granulosa cell anticoagulant heparan sulfate proteoglycans was studied using 125I-antithrombin binding assays. Follicle-stimulating hormone induced a redistribution of anticoagulant heparan sulfate proteoglycans from the granulosa cell layer to the culture medium, indicating that their distribution could be modulated according to the stage of follicular development. These results suggest that anticoagulant heparan sulfate might be critically located in the follicle to maintain fluidity around the oocyte until its expulsion at ovulation.

Abstract
[35S]Heparin proteoglycans were isolated from the skins and peritoneal mast cells of male rats aged 2 to 22 months. Their [35S]heparin chains were separated on antithrombin-agarose into fractions with high and low affinities for antithrombin. In skin, the proportion of 35S-labelled high-affinity heparin chains declined from 23% at 2 months to 8% at 12 months and did not change significantly between 12 and 22 months. In peritoneal mast cells, the proportion of 35S-labelled high-affinity heparin chains increased from 14% at 2 months to 21% at 4 months and then did not vary significantly until 15 months of age. By 21 months a consistent and significant decline to 8% occurred. The structures of high-affinity heparin proteoglycans did not change with age. Their decreased proportions, without change in their structure, may indicate that they are produced by a unique subset of mast cells, the proportion of which declines with age. [35S]heparan sulphate chains were isolated from skins and brains of rats in the same age range and fractionated on antithrombin-agarose. There were no significant variations in the proportions of 35S-labelled high-affinity heparan sulphate chains in skin (10%) or brain (24%) between 4 and 22 months of age.
