Abstract
OBJECTIVE Women have a higher prevalence and burden of joint injuries and pathologies involving articular cartilage than men. Although knee injuries affecting young women are on the rise, most studies related to sexual dimorphism target postmenopausal women. We hypothesize that sexual dimorphism in cartilage structure and mechanics is present before menopause, which can contribute to sex disparities in cartilage pathologies. DESIGN Bovine knee was used as a model to study healthy adult cartilage. We compared elastic moduli under compression, abundances of extracellular and pericellular matrix (PCM) proteins using proteomics, and PCM constituency with tissue immunofluorescence. The gene expression of matrix-related genes under basal, anabolic, and catabolic conditions was assessed by quantitative polymerase chain reaction (qPCR). RESULTS The equilibrium modulus was higher in male cartilage compared with female cartilage. Proteoglycans were not associated with this biomechanical dimorphism. Proteomic and pathway analyses of tissue showed dimorphic enriched pathways in extracellular matrix (ECM)-related proteins in which male cartilage was enriched in matrix interconnectors and crosslinkers that strengthen the ECM network. Moreover, male and female tissue differed in enriched PCM components. Females had more abundance of collagen type VI and decorin, suggesting different PCM mechanics. Furthermore, the activation of regenerative and catabolic function in chondrocytes triggered sex-dependent signatures in gene expression, indicating dimorphic genetic regulation that is dependent on stimulation. CONCLUSIONS We provide evidence for sexual dimorphism in cartilage before menopause. Some differences are intrinsic to chondrocytes' gene expression defined by their XX versus XY chromosomal constituency.

Abstract
AIMS Osteoarthritis (OA) is a common joint disease and the main cause of disability. We sought to determine the effective concentration of emodin on chondrocytes and to identify the dosage of emodin that induces a comparable therapeutic effect with the COX-2 inhibitor drug, celecoxib that is currently used to treat OA. MATERIAL AND METHODS In vitro experiments induced inflammation of chondrocytes by IL-1β, and an osteoarthritis model was established in vivo by cutting rat anterior cruciate ligament. Western Blot, Real-time PCR, HE staining, Safranin O-green staining and immunohistochemistry were performed to detect MMP-3, MMP-13, ADAMTS-4, iNOS and COL2A1 on the chondrocytes or the tibial plateau. The cytokine activity and content in serum of six groups of rats were measured by kit. RESULTS It was found that the surface layer of the cartilage was thicker and smoother after the administration of emodin. Tissue expression of MMP-3, MMP-13, ADAMTS-4 and iNOS were significantly (p < 0.05) decreased in chondrocytes and cartilage treated with different doses of emodin, and the content of COL2A1 was reversed. Emodin also significantly decreased the blood levels of COX-2 and PGE2. The effective emodin in vitro was 5 μmol/L, whereas emodin at 80 mg/kg was equivalent to celecoxib in vivo. CONCLUSION Emodin reduces the expression of cartilage matrix degradation biomarkers, thereby reducing the degradation of cartilage matrix and protecting the knee joint cartilage. Emodin at 5 μmol/L shows the best concentration to treat chondrocytes, and the protective effect of emodin at 80 mg/kg is comparable to that of celecoxib.

Abstract
Research on the vitreous humor and development of hydrogel vitreous substitutes have gained a rapid increase in interest within the past two decades. However, the properties of the vitreous humor and vitreous substitutes have yet to be consolidated. In this paper, the mechanical properties of the vitreous humor and hydrogel vitreous substitutes were systematically reviewed. The number of publications on the vitreous humor and vitreous substitutes over the years, as well as their respective testing conditions and testing techniques were analyzed. The mechanical properties of the human vitreous were found to be most similar to the vitreous of pigs and rabbits. The storage and loss moduli of the hydrogel vitreous substitutes developed were found to be orders of magnitude higher in comparison to the native human vitreous. However, the reported modulus for human vitreous, which was most commonly tested in vitro, has been hypothesized to be different in vivo. Future studies should focus on testing the mechanical properties of the vitreous in situ or in vivo. In addition to its mechanical properties, the vitreous humor has other biotransport mechanisms and biochemical functions that establish a redox balance and maintain an oxygen gradient inside the vitreous chamber to protect intraocular tissues from oxidative damage. Biomimetic hydrogel vitreous substitutes have the potential to provide ophthalmologists with additional avenues for treating and controlling vitreoretinal diseases while preventing complications after vitrectomy. Due to the proximity and interconnectedness of the vitreous humor to other ocular tissues, particularly the lens and the retina, more interest has been placed on understanding the properties of the vitreous humor in recent years. A better understanding of the properties of the vitreous humor will aid in improving the design of biomimetic vitreous substitutes and enhancing intravitreal biotransport.

Abstract
The vitreous humor is a fragile, transparent hydrogel situated between the lens and the retina, occupying 80% of the eye's volume. Due to its viscoelastic behavior, the vitreous serves as a mechanical damper for the eye, absorbing impacts, and protecting the lens and retina. The vitreous liquefies with age, which compromises its function as a shock absorber and causes complications including retinal detachment, macular holes, and vitreous hemorrhage. Studies on the viscoelastic properties of the vitreous have been limited. Rheological testing of the vitreous has commonly been done on non-primate mammalian species. Human vitreous rheological properties have been previously reported; however, various measurement techniques were used, resulting in data that differed by orders of magnitude. Shear rheometry is commonly used to characterize soft tissues and hydrogels such as the vitreous humor. However, no human vitreous rheological data have been reported using this technique, preventing direct comparison to other published work. Additionally, no age-related changes in the mechanical properties of the human vitreous humor have been reported. Human vitreous samples (n = 39, aged 62 ± 15 years) were tested using a shear rheometer. Small amplitude oscillatory shear and creep experiments were performed. The linear viscoelastic region of the human vitreous was found to be below 1% strain. The solid phase of the old human vitreous was found to be stiffer than the young human vitreous and the porcine vitreous. The stiffness of the human vitreous gel also appeared to be positively correlated with age. Vitreous dehydration due to a decrease in hyaluronic acid concentration with age was proposed to cause the stiffening of the solid phase of the vitreous gel. Vitreous liquefaction, therefore, might be characterized as a simultaneous increase in liquid volume and localized stiffening of the vitreous gel. The phase separation of the vitreous humor with age has been hypothesized as the cause of many vitreous-related complications. This study provides viscoelastic properties and age-related changes of the human vitreous humor, which will aid in the design of biomimetic vitreous substitutes, enhancement in analyzing intravitreal transport of therapeutics, and understanding the pathological conditions of the vitreous humor.

Abstract
PURPOSE Temporomandibular joint osteoarthritis (TMJOA) is an important subtype of temporomandibular disorder. This study investigated the inflammatory role of the stromal cell-derived factor-1 (SDF-1) and C-X-C chemokine receptor-4 (CXCR4) axis and the probable signaling pathway involved in matrix metalloprotease (MMP)-3 and MMP-9 productions stimulated by the SDF-1-CXCR4 axis in an experimental rat model of TMJOA. MATERIALS AND METHODS Rats were randomly divided into a control group, a pathologic model group, and an AMD3100 group. Effects of the bicyclam derivative AMD3100 (the specific antagonist of SDF-1-CXCR4 axis) were studied in TMJOA experimentally induced by monosodium iodo-acetate. Productions of SDF-1 and CXCR4 were compared in the normal and pathologic model groups, and cartilage changes and expressions of MMP-3, MMP-9, and phosphorylated extracellular signal-regulated kinase (p-ERK) were compared in the control, pathologic model, and AMD3100 groups. RESULTS Expressions of SDF-1 and CXCR4 in the pathologic model group were increased compared with the control group (P < .05). Releases of MMP-3, MMP-9, and p-ERK and cartilage changes were downregulated in the AMD3100 group compared with the pathologic model group (P < .05), and these changes occurred in a dose-dependent manner with AMD3100 concentrations. Moreover, there were strong predictive relations between the expression of p-ERK with MMP-3 (r(2) = 0.419; P < .001) and with MMP-9 (r(2) = 0.542; P < .001). CONCLUSIONS The SDF-1-CXCR4 signaling pathway plays a proinflammatory role in experimental TMJOA, the bicyclam derivative AMD3100 can alleviate the severity of experimental TMJOA, and there might be a potential relation between the SDF-1-CXCR4 axis and the ERK signaling pathway.

Abstract
Hox cluster genes play crucial roles in development of the metazoan antero-posterior axis. Functions of Hox genes in patterning the central nervous system and limb buds are well known. They are also expressed in chordate endodermal tissues, where their roles in endodermal development are still poorly understood. In the invertebrate chordate, Ciona intestinalis, endodermal tissues are in a premature state during the larval stage, and they differentiate into the digestive tract during metamorphosis. In this study, we showed that disruption of a Hox gene, Ci-Hox10, prevented intestinal formation. Ci-Hox10-knock-down larvae displayed defective migration of endodermal strand cells. Formation of a protrusion, which is important for cell migration, was disrupted in these cells. The collagen type IX gene is a downstream target of Ci-Hox10, and is negatively regulated by Ci-Hox10 and a matrix metalloproteinase ortholog, prior to endodermal cell migration. Inhibition of this regulation prevented cellular migration. These results suggest that Ci-Hox10 regulates endodermal strand cell migration by forming a protrusion and by reconstructing the extracellular matrix.

Abstract
BACKGROUND Osteoarthritis (OA) is an inflammatory disease of synovial joints involving the loss and degeneration of articular cartilage. The gold standard for evaluating cartilage loss in OA is the measurement of joint space width on standard radiographs. However, in most cases the diagnosis is made well after the onset of the disease, when the symptoms are well established. Identification of early biomarkers of OA can facilitate earlier diagnosis, improve disease monitoring and predict responses to therapeutic interventions. METHODS This study describes the bioinformatic analysis of data generated from high throughput proteomics for identification of potential biomarkers of OA. The mass spectrometry data was generated using a canine explant model of articular cartilage treated with the pro-inflammatory cytokine interleukin 1 β (IL-1β). The bioinformatics analysis involved the application of machine learning and network analysis to the proteomic mass spectrometry data. A rule based machine learning technique, BioHEL, was used to create a model that classified the samples into their relevant treatment groups by identifying those proteins that separated samples into their respective groups. The proteins identified were considered to be potential biomarkers. Protein networks were also generated; from these networks, proteins pivotal to the classification were identified. RESULTS BioHEL correctly classified eighteen out of twenty-three samples, giving a classification accuracy of 78.3% for the dataset. The dataset included the four classes of control, IL-1β, carprofen, and IL-1β and carprofen together. This exceeded the other machine learners that were used for a comparison, on the same dataset, with the exception of another rule-based method, JRip, which performed equally well. The proteins that were most frequently used in rules generated by BioHEL were found to include a number of relevant proteins including matrix metalloproteinase 3, interleukin 8 and matrix gla protein. CONCLUSIONS Using this protocol, combining an in vitro model of OA with bioinformatics analysis, a number of relevant extracellular matrix proteins were identified, thereby supporting the application of these bioinformatics tools for analysis of proteomic data from in vitro models of cartilage degradation.

Abstract
The mechanism of chain selection and trimerization of fibril-associated collagens with interrupted triple helices (FACITs) differs from that of fibrillar collagens that have special C-propeptides. We recently showed that the second carboxyl-terminal non-collagenous domain (NC2) of homotrimeric collagen XIX forms a stable trimer and substantially stabilizes a collagen triple helix attached to either end. We then hypothesized a general trimerizing role for the NC2 domain in other FACITs. Here we analyzed the NC2 domain of human heterotrimeric collagen IX, the only member of FACITs with all three chains encoded by distinct genes. Upon oxidative folding of equimolar amounts of the alpha1, alpha2, and alpha3 chains of NC2, a stable heterotrimer with a disulfide bridge between alpha1 and alpha3 chains is formed. Our experiments show that this heterotrimerization domain can stabilize a short triple helix attached at the carboxyl-terminal end and allows for the proper oxidation of the cystine knot of type III collagen after the short triple helix.

Abstract
The matrix metalloproteinase enzyme MMP-13 plays a key role in the degradation of type II collagen in cartilage and bone in osteoarthritis (OA). An effective MMP-13 inhibitor would therefore be a novel disease modifying therapy for the treatment of arthritis. Our efforts have resulted in the discovery of a series of carboxylic acid inhibitors of MMP-13 that do not significantly inhibit the related MMP-1 (collagenase-1) or tumor necrosis factor-alpha (TNF-alpha) converting enzyme (TACE). It has previously been suggested (but not proven) that inhibition of the latter two enzymes could lead to side effects. A promising carboxylic acid lead 9 was identified and a convergent synthesis developed. This paper describes the optimization of 9 and the identification of a compound 24f for further development. Compound 24f is a subnanomolar inhibitor of MMP-13 (IC(50) value 0.5 nM and K(i) of 0.19 nM) having no activity against MMP-1 or TACE (IC(50) of >10000 nM). Furthermore, in a rat model of MMP-13-induced cartilage degradation, 24f significantly reduced proteoglycan release following oral dosing at 30 mg/kg (75% inhibition, p < 0.05) and at 10 mg/kg (40% inhibition, p < 0.05).

Abstract
Arthritis is one of the most prevalent chronic inflammatory diseases, and it is characterized by structural and biochemical changes in major tissues of the joint, including degradation of the cartilage matrix, insufficient synthesis of extracellular matrix (ECM). Ecklonia cava (EC) is a member of the family of Laminariaceae, which is an edible marine brown alga with various bioactivities. In this study of the methanol extract of brown alga EC, the dieckol (1) and 1-(3',5'-dihydroxyphenoxy)-7-(2'',4'',6''-trihydroxyphenoxy) 2,4,9-trihydroxydibenzo-1,4,-dioxin (2) were isolated and characterized by NMR techniques with high yield. Phlorotannin derivatives (1, 2) promoted osteosarcoma differentiation by increasing alkaline phosphatase (ALP) activity, mineralization, total protein and collagen synthesis in human osteosarcoma cell (MG-63 cells), respectively. Furthermore, these phlorotannin derivatives (1, 2) inhibited mRNA gene and protein levels of matrix metalloproteinase (MMP-1, MMP-3, and MMP-13), iNOS and COX-2 in casein zymography, Western blot and reverse transcriptase-polymerase chain reaction (RT-PCR) assays. In addition, it was observed that the phlorotannins inhibited phosphorylation of JNK and p38 MAPK in human osteosarcoma cell. These results suggested the phlorotannin derivatives (1, 2) could promote cell differentiation, attenuate MMP-1, MMP-3, MMP-13 expressions, and inflammatory response via MAPK pathway in chronic articular diseases.

Abstract
AIM Hepatocyte growth factor (HGF) has various biological properties, including antifibrogenic activity. In the present study, we tested the efficacy of HGF gene therapy using naked plasmid DNA in dimethylnitrosamine (DMN)-induced liver fibrosis in a rat model. METHODS Naked plasmid DNA encoding human HGF was injected once, together with a hypertonic solution, into the hepatic artery after DMN treatment on three consecutive days per week for 3 weeks. Naked plasmid DNA encoding beta-galactosidase was injected similarly in the DMN-treated control rats. DMN treatment was continued once weekly after gene transfer for additional 3 weeks. RESULTS The human HGF protein expression was detected in livers transfected with human HGF naked plasmid DNA, gradually decreasing by day 21. The expression of the endogenous rat HGF protein was also upregulated after human HGF gene transfer. Phosphorylation of c-Met, a HGF receptor, was detected only in livers transfected with human HGF plasmid DNA. Fibrosis was attenuated significantly in livers transfected with the human HGF plasmid. Attenuation wasaccompanied by decreased expression of alpha-smooth muscle actin. Increased portal vein pressure after treatment with DMN was suppressed significantly by HGF gene transfer. The upregulated hepatic protein expression of transforming growth factor-beta (TGF-beta) in response to DMN was markedly attenuated by HGF gene transfer accompanied by the increased protein expression for matrix metalloproteinases (MMP)-3 and -13. CONCLUSION The hepatic arterial injection of human naked plasmid HGF DNA was effective in suppressing liver fibrosis induced in rats by DMN. The mechanisms by which HGF expression attenuated liver fibrosis may include the suppression of hepatic TGF-beta expression and the induction of MMP expression.

Abstract
The preservation of articular cartilage depends on keeping the cartilage architecture intact. Cartilage strength and function depend on both the properties of the tissue and on their structural parameters. The main structural macromolecules are collagen and proteoglycans (aggrecan). During life, cartilage matrix turnover is mediated by a multitude of complex autocrine and paracrine anabolic and catabolic factors. These act on the chondrocytes and can lead to repair, remodeling or catabolic processes like those that occur in osteoarthritis. Osteoarthritis is characterized by degradation and loss of articular cartilage, subchondral bone remodeling, and, at the clinical stage of the disease, inflammation of the synovial membrane. The alterations in osteoarthritic cartilage are numerous and involve morphologic and metabolic changes in chondrocytes, as well as biochemical and structural alterations in the extracellular matrix macromolecules.

Abstract
Recent studies have identified a range of interactions between type IX collagen and other cartilage matrix components. To determine the extent to which these interactions are important in maintaining the integrity of ageing articular cartilage, we analyzed an age range of normal healthy articular cartilage samples by Western blotting, immunohistochemical, and PCR analyses. Reduced levels of type IX collagen were detected in post adolescence cartilage. Type IX collagen epitopes were evident throughout the matrix in all cartilage samples up to 19 years of age. Post adolescence, however, the pattern of immunoreactivity revealed territorial staining only. Type IX collagen expression at the transcriptional level is maintained at all ages. Type IX collagen fragments were extracted from young tissue, supporting the hypothesis that young cartilage is continually remodelled, while mature cartilage maintains relatively low levels of collagen turnover. Clearly the age changes we observed may have significant effects on the integrity of the tissue as the chondrocytes in ageing articular cartilage have limited capacity to turnover the interterritorial matrix. However, this study provides evidence that even in old age, the chondrocyte attempts to maintain its pericellular environment and hence its mechanical role. Therefore, the potential of type IX collagen to interact with other matrix components continues to be of importance in the territorial environment, and these interactions may have significant roles in mechanotransduction.

Abstract
Degradation of bovine nasal cartilage induced by interleukin-1 (IL-1) was used to study catabolic events in the tissue over 16 days. Culture medium was fractionated by two-dimensional electrophoresis (isoelectric focusing and SDS-PAGE). Identification of components by peptide mass fingerprinting revealed released fragments representing the NC4 domain of the type IX collagen alpha1 chain at days 12 and 16. A novel peptide antibody against a near N-terminal epitope of the NC4 domain confirmed the finding and indicated the presence of one of the fragments already at day 9. Mass spectrometric analysis of the two most abundant fragments revealed that the smallest one contained almost the entire NC4 domain cleaved between arginine 258 and isoleucine 259 in the sequence -ETCNELPAR258-COOH NH2-ITP-. A larger fragment contained the NC4 domain and the major part of the COL3 domain with a cleavage site between glycine 400 and threonine 401 in COL3 (-RGPPGPPGPPGPSG400-COOH NH2-TIG-). The presence of multiple collagen alpha1 (IX) N-terminal sequences demonstrates that the released molecules were cleaved at sites very close to the original N terminus either prior to or due to IL-1 treatment. Matrix metalloproteinase 13 (MMP-13) is active and cleaves fibromodulin in the time interval studied. Cartilage explants treated with MMP-13 were shown to release collagen alpha1 (IX) fragments with the same sizes and with the same cleavage sites as those obtained upon IL-1 treatment. These data describe cleavage by an MMP-13 activity toward non-collagenous and triple helix domains. These potentially important degradation events precede the major loss of type II collagen.

Abstract
CONTEXT Matrix metalloproteinase 3 (MMP-3) is expressed in synovial tissues and involved in cartilage destruction in rheumatoid arthritis and osteoarthritis. OBJECTIVE To study whether measurement of MMP-3 serum concentrations is useful to monitor the activity of rheumatoid synovitis. DESIGN Levels of MMP-3 in serum and synovial tissue samples obtained from 29 rheumatoid arthritis patients and 20 osteoarthritis patients were measured by the 1-step sandwich enzyme immunoassay system. RESULTS Levels of MMP-3 in the serum and synovial samples were significantly higher in rheumatoid arthritis than in osteoarthritis (P < .001), and the levels correlated directly with each other (r = 0.712, P < .001; N = 49). Immunohistochemistry demonstrated almost exclusive localization of MMP-3 to the lining cells in rheumatoid synovium. The immunoreactivity correlated directly with the scores of synovial inflammatory cell infiltration (r = 0.606, P < .001; n = 29) and the MMP-3 levels in the synovial tissues (r = 0.564, P = .001; n = 29) and those in the serum samples (r = 0.529, P = .003; n = 29) in rheumatoid arthritis. Levels of MMP-3 in rheumatoid serum samples dropped to low values at 1 and 2 weeks after total knee arthroplasty, while the levels of C-reactive protein increased at 1 week and the erythrocyte sedimentation rate and counts of white blood cells and platelets were unchanged at 1 and 2 weeks postoperative. CONCLUSIONS Our results demonstrate that MMP-3 levels in the serum of rheumatoid arthritis patients correlate with the levels produced by the synovial lining cells and suggest that the activity of rheumatoid synovitis can be monitored by measuring serum levels of MMP-3.

Abstract
Odontogenesis involves a complex series of processes including epithelial-mesenchymal interactions, morphogenesis, differentiation, fibrillogenesis, and mineralization. Extracellular (ECM) remodeling plays a critical role in the rapid morphological changes that accompany these events. It is proposed that matrix metalloproteinases (MMPs) participate in the remodeling of tooth-specific matrices that accompanies the developmental events. MMPs are zinc-requiring endopeptidases that are centrally involved in the controlled turnover of ECM components and are key to a varied range of developmental processes. Thus, the aim of this study was to examine the expression of MMPs 1, 2, 3, and 9 within the developing tooth germ of Wistar rats, using immunohistochemical localisation. During the bud stage, MMPs 1, 2, 3, and 9 were expressed within both epithelial and mesenchymal cells. Later on, during the cap stage, differential expression was observed; of note was the expression of MMP 3 within the enamel knot. This study reports the temperospatial expression of MMPs 1, 2, 3, and 9 during early tooth development, and points to them having a key role during this important developmental period.

Abstract
OBJECTIVE To study the effect of polysulfated glycosaminoglycan (PSGAG) on proteoglycan metabolism and DNA content of control and osteoarthritic (OA) cartilage. STUDY DESIGN An in vitro study comparing the effects of PSGAG on articular cartilage explants from canine stifle joints with and without chronic OA after transection of the left cranial cruciate ligament. SAMPLE POPULATION Five large cross-breed dogs. METHODS Cartilage explants (6 to 13 per treatment group) from the medial side of the femoral trochlea and medial femoral condyle from both stifles of each dog were incubated in a defined medium containing 0, 0.05, 0.5, or 5 mg/mL of PSGAG. After 72 hours in culture, explants were pulsed for 6 hours with sodium [35S]sulfate. Aminophenylmercuric acetate (APMA) was used to activate endogenous neutral matrix metalloproteinases (MMPs) and induce proteoglycan degradation in the radiolabeled explants. DNA content and radioactivity were measured in papain-digested explants, and radioactivity was measured in the medium by liquid scintillation counting. Proteoglycan synthesis and degradation were calculated. Cartilage was examined histologically for signs of OA. A mixed model analysis of variance and linear contrasts were used to test for significant (P < .05) effects of OA and treatment with PSGAG. RESULTS Transection of the cranial cruciate ligament produced OA in operated joints. DNA content and proteoglycan synthesis of OA cartilage were significantly lower than in cartilage from control joints. For both DNA content and proteoglycan synthesis, significant interactions occurred between the concentration of PSGAG and whether the articular cartilage was from OA or control joints. The two lower concentrations of PSGAG (0.05 and 0.5 mg/mL) predominantly increased DNA content in OA cartilage (7 and 18%, respectively, compared with 0 mg/mL PSGAG) while the highest concentration (5 mg/mL) predominantly increased DNA content in control cartilage (30% compared with 0 mg/mL PSGAG). PSGAG at .05 mg/mL predominantly decreased proteoglycan synthesis in OA cartilage (19% reduction compared with 0 mg/mL PSGAG) while PSGAG at .5 and 5 mg/mL predominantly decreased proteoglycan synthesis in control cartilage (17 and 55% reduction, respectively, compared with 0 mg/mL PSGAG). Following activation of MMPs, PSGAG caused a dose-dependent decrease in degradation of radiolabeled proteoglycan in both OA and control cartilage. CONCLUSIONS OA cartilage was responsive to treatment with PSGAG at 100-fold lower concentration than control cartilage. When treated with PSGAG, articular cartilage explants maintained or increased DNA content at the expense of proteoglycan synthesis. Following MMP activation, proteoglycan degradation was inhibited in OA and control explants in a dose-dependent manner. CLINICAL RELEVANCE If the results of this study extend to in vivo use, treatment with PSGAG may modify the progression of OA in articular cartilage by maintaining chondrocyte viability or stimulating chondrocyte division as well as protecting against extracellular matrix degradation.

Abstract
This study aimed at assessing the possible diagnostic value of cartilage biopsies as a convenient marker for cartilage matrix degradation. We therefore examined cartilage specimens from 56 patients with primary osteoarthritis (OA) of the knee. Resection and biopsy cartilage specimens obtained during joint replacement surgery were used for this study. In addition to histomorphology, immunohistochemistry (ICH) was performed to determine the expression levels and distribution patterns of stromelysin and u-PA protein. The latter data were compared with the degree of histomorphological changes in osteoarthritic cartilage samples, based on a modified version of Mankin's grading score. Compared to the cartilage resection specimens, the biopsies showed comparable expression patterns for both proteinases: the strongest signals were noted in the superficial zone and, as matrix destruction increased, also in the chondrocytes of the transition and deep zones. The strongest signals were ascertained in cell clusters beneath deep matrix fissures. At the immunohistochemical level, we found a direct correlation in the expression of MMP-3 and u-PA between resection specimens and biopsies. Furthermore, in both types of cartilage samples, we noticed a positive relationship between the expression of both proteins and the Mankin score. Analysis of the expression levels revealed significant differences between deep, transition and superficial zones. Histomorphological and immunohistochemical examinations of MMP-3 and u-PA in biopsies of osteoarthritic cartilage turned out to be useful for estimating the pathological changes within osteoarthritic knee joints. Therefore, in future, cartilage biopsies from osteoarthritic knee joints might serve as a diagnostic tool and thus have an influence on further therapeutic strategies.

Abstract
OBJECTIVES Structure-modifying osteoarthritis (OA) drugs (SMOADs) may be defined as agents that reverse, retard, or stabilize the underlying pathology of OA, thereby providing symptomatic relief in the long-term. The objective of this review was to evaluate the literature on sodium pentosan polysulfate (NaPPS) and calcium pentosan polysulfate (CaPPS), with respect to the pathobiology of OA to ascertain whether these agents should be classified as SMOADs. METHODS Published studies on NaPPS and CaPPS were selected on the basis of their relevance to the known pathobiology of OA, which also was reviewed. RESULTS Both NaPPS and CaPPS exhibit a wide range of pharmacological activities. Of significance was the ability of these agents to support chondrocyte anabolic activities and attenuate catabolic events responsible for loss of components of the cartilage extracellular matrix in OA joints. Although some of the anti-catabolic activities may be mediated through direct enzyme inhibition, NaPPS and CaPPS also have been shown to enter chondrocytes and bind to promoter proteins and alter gene expression of matrix metalloproteinases and possibly other mediators. In rat models of arthritis, NaPPS and CaPPS reduced joint swelling and inflammatory mediator levels in pouch fluids. Moreover, synoviocyte biosynthesis of high-molecular-weight hyaluronan, which is diminished in OA, was normalized when these cells were incubated with NaPPS and CaPPS or after intraarticular injection of NaPPS into arthritic joints. In rabbit, canine, and ovine models of OA, NaPPS and CaPPS preserved cartilage integrity, proteoglycan synthesis, and reduced matrix metalloproteinase activity. NaPPS and CaPPS stimulated the release of tissue plasminogen activator (t-PA), superoxide dismutase, and lipases from vascular endothelium while concomitantly decreasing plasma levels of the endogenous plasminogen activator inhibitor PAI-1. The net thrombolytic and lipolytic effects exhibited by NaPPS and CaPPS may serve to improve blood flow through subchondral capillaries of OA joints and improve bone cell nutrition. In geriatric OA dogs, NaPPS and CaPPS reduced symptoms, as well as normalized their thrombolytic status, threshold for platelet activation, and plasma triglyceride levels. These hematologic parameters were shown to be abnormal in OA animals before drug treatment. Similar outcomes were observed in OA patients when CaPPS or NaPPS were given orally or parenterally in both open and double-blind trials. CONCLUSIONS The data presented in this review support the contention that NaPPS and CaPPS should be classified as SMOADs. However, additional long-term clinical studies employing methods of assessing joint structural changes will be needed to confirm this view.

Abstract
To determine whether matrix metalloproteinase-1 (MMP-1) or MMP-3 is involved in cartilage collagen degradation, polyclonal antibodies were separately raised against MMP-1 and MMP-3 and their effects on collagen degradation were assessed in rabbit cartilage explant culture. We found that anti-MMP-1 antibodies completely inhibited collagen degradation induced by the combination of interleukin-1 (IL-1) and plasminogen. Anti-MMP-3 antibodies showed 40% inhibition at maximum concentration. These results indicate that MMP-1, and possibly MMP-3, are involved in collagen degradation in cartilage explant culture.

Abstract
A critical event in avian corneal development occurs when the acellular primary stroma swells and becomes populated by mesenchymal cells that migrate from the periphery. These cells then deposit the mature stromal matrix that exhibits the unique features necessary for corneal function. Our previous work correlated the disappearance of collagen type IX immunoreactivity at stage 27 (5 1/2-6 days) with matrix swelling and invasion. To investigate further the mechanism of this disappearance, we employed immunohistochemistry after tissue fixation with Histochoice, a non-crosslinking fixative, immunoblot analysis of protein extracts, and gel substrate chromatography (zymography) to detect endogenous proteolytic activity. We found that corneas fixed in Histochoice retain immunoreactivity for type IX collagen for 1-2 days after corneal swelling. This immunoreactivity, however, becomes extractable from tissue sections of unfixed corneas at the time of initiation of stromal swelling and mesenchymal cell invasion. Immunoblot analysis confirmed that, following swelling, immunoreactivity for collagen IX decreased substantially in corneas, but not in the vitreous body, which served as a comparison. Analysis of ammonium sulfate (AS) fractions of such extracts indicated that, at the time of swelling, much of the immunoreactivity for type IX collagen in cornea shifted from the AS precipitate (containing high molecular weight molecules) to the AS supernatant (containing smaller fragments). In contrast, collagen IX immunoreactivity from the vitreous was precipitated by ammonium sulfate throughout the period of study. Collagen type II, a major fibrillar collagen in both the corneal stroma and vitreous, remained in the high molecular weight fraction at all times examined. Zymography detected the presence of the latent (proenzyme) form of gelatinase A (MMP-2) before corneal swelling and invasion (4 days), and both the latent and active forms of the enzyme after corneal swelling. This suggests tissue-specific, developmentally regulated proteolysis of collagen IX as a trigger for corneal matrix swelling.

Abstract
The in-vitro effects of avocado and soybean unsaponifiable residues on neutral metalloproteinase activity, cytokines and prostaglandin E2 (PGE2) production by human articular chondrocytes were investigated. Avocado and soybean unsaponifiable residues were mixed in three ratios: 1:2 (A1S2), 2:1 (A2S1) or 1:1 (A2S2). Freshly isolated human chondrocytes were cultured for 72 h in the absence or presence of interleukin-1beta, (IL-1beta) (17 ng/ml), with or without unsaponifiable residue mixtures at a concentration of 10 microg/ml. A/S unsaponifiable residues were also tested separately at concentrations of 3.3, 6.6 and 10 microg/ml. All A/S unsaponifiable mixtures reduced the spontaneous production of stromelysin, interleukin-6 (IL-6), interleukin-8 (IL-8) and prostaglandin E2 (PGE2) by chrondrocytes. At concentrations of 3.3 and 6.6 microg/ml, A/S residues, tested separately, were potent inhibitors of the production of IL-8 and PGE2. Nevertheless, only avocado residue inhibited IL-6 production at these concentrations. A/S unsaponifiable mixtures had a more pronounced inhibitory effect on cytokine production than avocado or soybean residues added alone. As anticipated, IL-1beta induced a marked release of collagenase, stromelysin, IL-6, IL-8 and PGE2. A/S unsaponifiable mixtures partially reversed the IL-1 effects on chrondrocytes. These findings suggest a potential role for A/S unsaponifiable extracts in mitigating the deleterious effects of IL-1beta: on cartilage.

Abstract
OBJECTIVE It has long been proposed that stromelysin is one of the major degradative matrix metalloproteinases responsible for the loss of cartilage in rheumatoid arthritis (RA) and osteoarthritis (OA). This hypothesis was tested by examining the arthritic paws of stromelysin 1 (SLN1)-deficient mice for loss of cartilage and for generation of neoepitopes that would be indicative of aggrecan cleavage. METHODS The SLN1 gene was inactivated in murine embryonic stem cells, and knockout mice deficient in SLN1 activity were bred onto the B10.RIII background. The incidence and severity of collagen-induced arthritis (CIA) were compared in wild-type and knockout mice. Paws from mice with CIA were examined for loss of cartilage and for proteoglycan staining, as well as for the generation of the neoepitope FVDIPEN341. RESULTS SLN1-deficient mice developed CIA, as did the wild-type N2 mice. Histologic analyses demonstrated no significant differences among the B10.RIII, wild-type, and knockout mice in loss of articular cartilage and proteoglycan staining. No decrease in the FVDIPEN341 epitope was observed in the SLN1-deficient mice. CONCLUSION Disruption of the SLN1 gene neither prevents nor reduces the cartilage destruction associated with CIA. Moreover, SLN1 depletion does not prevent the cleavage of the aggrecan Asn341-Phe342 bond.

Abstract
MATRIX METALLOPROTEINASE-3 (MMP-3), or stromelysin-1, is an enzyme responsible for the degradation of a wide range of extracellular matrix proteins. Increases in MMP-3 activity have been found in several chronic inflammatory diseases, and this increased activity is thought to be mediated by interleukin-1 beta (IL-1 beta). Because IL-1 beta has been strongly associated with inflammatory periodontal disease, the purpose of this in vitro study was to investigate the role of IL-1 beta on the regulation of MMP-3 levels in cells derived from the human periodontal ligament (PDL). Human PDL cell cultures were treated with IL-1 beta at varying concentrations (0.01-1.0 ng/ml) for 24 hour prior to analysis at either transcript or protein levels. Following the isolation of total RNA, the relative levels of MMP-3 mRNA were determined using reverse transcription-polymerase chain reaction (RT-PCR) with 32P-end-labeled primers. Immunocytochemical detection of MMP-3 protein was performed using polyclonal antibodies to human MMP-3. The results of RT-PCR analysis demonstrated a concentration-dependent increase in MMP-3 mRNA expression, with IL-1 beta treatments of 0.1 and 1.0 ng/ml significantly (P < 0.01) increased over those cells not treated with IL-1 beta. This increase in mRNA expression was paralleled by significant (P < 0.001) changes at the protein level, with an average of 27.6% of the cells stained positive for MMP-3 following IL-1 beta treatment (1.0 ng/ml), compared with control cells showing no positive staining for MMP-3. In conclusion, the results of this study demonstrate that IL-1 beta upregulates MMP-3 in human PDL cells on both an mRNA and a protein level. These findings suggest possibly important roles for IL-1 beta and MMP-3 in both normal turnover and maintenance of the PDL and in the connective tissue degradation associated with periodontal disease.

Abstract
STUDY DESIGN This study is a unique in vitro study on the effects of hydrostatic pressure on human intervertebral disc metabolism. OBJECTIVE To investigate the effects of hydrostatic pressure on matrix synthesis and matrix metalloproteinase production in the human lumbar intervertebral disc. SUMMARY OF BACKGROUND DATA Mechanical stress and hydrostatic pressures influence proteoglycan and protein synthesis rates in bovine articular cartilage and coccygeal discs. However, the mechanism of matrix synthesis regulation of the intervertebral disc under mechanical stress has not been elucidated. METHODS Twenty-eight human lumbar intervertebral discs obtained from surgery and from cadavers at autopsy were used. Each tissue fraction was charged with medium in a plastic syringe and placed in a water-filled hydrostatic pressure-control vessel. The hydrostatic pressures applied were 1 (control), 3, and 30 atm (atm = atmospheres) for 2 hours. The proteoglycan and protein synthesis rates were determined by radioisotope incorporation. The production of matrix metalloproteinase-3 and tissue inhibitor of metalloproteinases-1 were measured by a one-step enzyme immunoassay method using monoclonal antibodies. RESULTS Three atm pressure stimulated proteoglycan synthesis rates in the nucleus pulposus and inner anulus (n = 14 in each tissue). Compared with the control group, 30 atm pressure significantly inhibited proteoglycan synthesis in the inner anulus (P = 0.011). In the nucleus pulposus, matrix metalloproteinase-3 production was stimulated at a pressure of 30 atm relative to 3 atm (P = 0.014, n = 16 in each tissue). The highest tissue inhibitor of metalloproteinases-1 production showed highest values at 3 atm pressure in the inner anulus (n = 16 in each tissue). CONCLUSION The results suggest that hydrostatic pressure influences intervertebral disc cell metabolism. A physiologic level of hydrostatic pressure (3 atm) may act as an anabolic factor for stimulation of proteoglycan synthesis and tissue inhibitor of metalloproteinases-1 production. This may be essential for maintaining the matrix of the disc. If the pressure was 30 atm or more or 1 atm or less, a catabolic effect will be predominant, with reduction of proteoglycan synthesis rate and increase of matrix metalloproteinase-3 production. Abnormal hydrostatic pressure, therefore, may accelerate disc degeneration.

Abstract
Recombinant human procollagenase-3 and a C-terminal truncated form (Delta249-451 procollagenase-3) have been stably expressed in myeloma cells and purified. The truncated proenzyme could be processed by aminophenylmercuric acetate via a short-lived intermediate form (N-terminal Leu58) to the final active form (N-terminal Tyr85). The kinetics of activation were not affected by removal of the hemopexin-like C-terminal domain. The specific activities of both collagenase-3 and Delta249-451 collagenase-3 were found to be similar using two quenched fluorescent substrates, but Delta249-451 collagenase-3 failed to cleave native triple helical collagens (types I and II) into characteristic one- and three-quarter fragments. It was noted, however, that the beta1,2(I) chains of type I collagen were susceptible to Delta249-451 collagenase-3, which indicates that the catalytic domain displays telopeptidase activity, thereby generating alpha1,2(I) chains that are slightly shorter than those in native type I collagen. It can be concluded that the C-terminal domain is only essential for the triple helicase activity of collagenase-3. Binding of procollagenase-3 and active collagenase-3 to type I collagen is mediated by the C-terminal domain. Both collagenase-3 and Delta249-451 collagenase-3 hydrolyzed the large tenascin C isoform, fibronectin, recombinant fibronectin fragments, and type IV, IX, X, and XIV collagens; thus, these events were independent from C-terminal domain interactions. In contrast, the minor cartilage type XI collagen was resistant to cleavage. Kinetic analysis of the mechanism of inhibition of wild-type and Delta249-451 collagenase-3 by wild-type and mutant tissue inhibitors of metalloproteinase (TIMPs) revealed that the association rates for complex formation were influenced by both N- and C-terminal domain interactions. The C-terminal domain of wild-type collagenase-3 promoted increased association rates with the full-length inhibitors TIMP-1 and TIMP-3 and the hybrid N.TIMP-2/C.TIMP-1 by a factor of up to 33. In contrast, the association rates for complex formation with TIMP-2 and N.TIMP-1/C.TIMP-2 were only marginally affected by C-terminal domain interactions.

Abstract
Matrix metalloproteinases (MMPs) secreted by connective tissue cells are capable of acting on extracellular matrix components of glomerular basement membrane at a slow rate and thus may play a role in the control of protein permeability and in the progression of certain kinds of glomerulonephritis. We have used an in vitro assay to measure the direct effect of three MMPs and human neutrophil elastase on glomerular albumin permeability (Palbumin). Glomeruli were isolated from normal male Sprague-Dawley rats and suspended in isolation medium with or without interstitial collagenase, gelatinase-A, stromelysin-1, or elastase and were incubated at 37 degrees C for up to 4 hours. A tissue-specific inhibitor of matrix metalloproteinases (TIMP-1) and a plasma proteinase inhibitor, alpha2-macroglobulin (alpha2M), were used to block the activity of MMPs. Palbumin was calculated from the change in glomerular volume in response to an applied oncotic gradient. In this study stromelysin-1 (10 microg/ml) and elastase (5 microg/ml) increased Palbumin significantly. Stromelysin-1 increased Palbumin after 4 hours, whereas elastase had an effect after 2 hours. Lower concentrations of stromelysin-1 or shorter incubation time had no effect on Palbumin. Incubation for up to 4 hours with interstitial collagenase (10 microg/ml) or gelatinase-A (10 microg/ml) had no effect on Palbumin. Coincubation with TIMP-1 and alpha2M blocked the stromelysin-1-mediated increase in Palbumin. We conclude that stromelysin-1 is capable of affecting the glomerular filtration barrier directly and that it may play an important role in causing proteinuria in glomerular diseases.

Abstract
We examined the expression of stromelysin mRNA (SL mRNA) in synovial biopsy specimens from 12 cases of rheumatoid arthritis (RA) and 2 cases of osteoarthritis (OA) using in situ hybridization. The study demonstrated that positive cells with high levels of SL mRNA were mostly (85%) found in the synovial lining layer. The positive cells were abundant in the synovium of RA which presented well developed lymphoid follicles with massive inflammatory cells. On the other hand, the synovium of OA contained no positive cells for SL mRNA. In addition, low yet positive levels of SL mRNA were detected in the endothelial cells and vascular myocytes, and interstitial cells in the deeper layer of the synovium. Karyometric studies showed that cells positive for SL mRNA had significantly larger and more spherical nuclei than weakly positive or negative cells. The SL mRNA positive cells did not demonstrate any immunoreactivity to markers of bone marrow origin, such as Leu M1, Leukocyte Common Antigen (LCA) and lysozyme antigen. Electron microscopy of a case with many SL mRNA positive cells showed that most had well developed rough endoplasmic reticulum and numerous processes on the cell surface, and some had also well developed rough endoplasmic reticulum but without processes indicating that they may be AB and/or B synoviocytes.

Abstract
Matrix metalloproteinases (MMP) play a cardinal role in the breakdown of extracellular matrix involved in a variety of biological and pathological processes. Research on MMPs has classified and characterized these enzymes according to their matrix substrate specificity, gene and protein domain structure, and regulation of activity and expression. However, the discovery of new MMPs has introduced a need for a more comprehensive and systematic method of classification and quantitative comparison of known and newly discovered members. This study compiles a sequence alignment, constructs a dendrogram, and calculates physical data and homology percentage assignments in order to obtain further insight into MMP structure-function relationships. Thorough analysis of MMP primary sequence domains, physical data patterns, and statistical analysis of sequence homology yields higher resolution in the similarities and differences that group MMP members.

Abstract
STUDY DESIGN Immunohistologic staining of human intervertebral discs collected at the time of surgery (100 intervertebral discs from 80 patients) and 10 discs collected from 7 cadavers within 12 hours of death was performed using antimatrix metalloproteinase-3 monoclonal antibody and antitissue inhibitor of metalloproteinase-1 monoclonal antibody. OBJECTIVES To examine the relationship between matrix destruction and staining for matrix metalloproteinase-3 and tissue inhibitor of metalloproteinase-1 in intervertebral disc degeneration. SUMMARY OF BACKGROUND DATA Matrix metalloproteinase-3, which decomposes aggregating proteoglycans, has attracted research attention as a substance contributing to matrix destruction in the articular cartilage and intervertebral disc. However, except for a few in vitro studies, the relationship between matrix destruction of the intervertebral disc and matrix metalloproteinase-3 has been little studied. METHODS Immunohistologic staining was performed to examine the relationship between matrix metalloproteinase-3 and tissue inhibitor of metalloproteinase-1 in the intervertebral disc, and the relationship of these two agents to magnetic resonance imaging, radiographic, and surgical findings. RESULTS Those cases testing positive for matrix metalloproteinase-3 and negative for tissue inhibitor of metalloproteinase-1 accounted for most of the surgical specimens. The matrix metalloproteinase-3-positive cell ratio was significantly correlated with the magnetic resonance imaging grade of intervertebral disc degeneration, and the matrix metalloproteinase-3-positive cell ratio observed in prolapsed lumbar intervertebral discs was significantly higher than that in nonprolapsed discs. In cervical intervertebral discs, the matrix metalloproteinase-3-positive cell ratio and staining of cartilaginous endplate were correlated with the size of osteophyte formation. CONCLUSIONS These findings suggested that intervertebral disc degeneration is caused by disturbance in the equilibrium of matrix metalloproteinase-3 and tissue inhibitor of metalloproteinase-1, and that matrix metalloproteinase-3 contributes to degeneration of the cartilaginous endplate.

Abstract
The proteolytic enzyme stromelysin-1 is a member of the family of matrix metalloproteinases and is believed to play a role in pathological conditions such as arthritis and tumor invasion. Stromelysin-1 is synthesized as a pro-enzyme that is activated by removal of an N-terminal prodomain. The active enzyme contains a catalytic domain and a C-terminal hemopexin domain believed to participate in macromolecular substrate recognition. We have determined the three-dimensional structures of both a C-truncated form of the proenzyme and an inhibited complex of the catalytic domain by X-ray diffraction analysis. The catalytic core is very similar in the two forms and is similar to the homologous domain in fibroblast and neutrophil collagenases, as well as to the stromelysin structure determined by NMR. The prodomain is a separate folding unit containing three alpha-helices and an extended peptide that lies in the active site of the enzyme. Surprisingly, the amino-to-carboxyl direction of this peptide chain is opposite to that adopted by the inhibitor and by previously reported inhibitors of collagenase. Comparison of the active site of stromelysin with that of thermolysin reveals that most of the residues proposed to play significant roles in the enzymatic mechanism of thermolysin have equivalents in stromelysin, but that three residues implicated in the catalytic mechanism of thermolysin are not represented in stromelysin.

Abstract
OBJECTIVE To examine the effects of tenidap and diclofenac on osteoarthritic lesions and metalloprotease activity in experimental osteoarthritis (OA). METHODS The anterior cruciate ligament of the right stifle joint of 25 mongrel dogs was sectioned by a stab wound. Seven dogs received no treatment, 6 were treated with oral omeprazole (20 mg/day), another 6 were treated with diclofenac (0.25 mg/kg/twice daily) plus omeprazole (20 mg/day), and 6 received oral tenidap (3 mg/kg/twice daily) plus omeprazole (20 mg/day). The dogs received medication for 8 weeks; all dogs were killed at the end of this period. Eight normal dogs were used as controls. Lesions were evaluated macroscopically for the incidence and size of osteophytes and the area and grade of cartilage erosions on the condyles and plateaus, along with histologic evaluation of the severity of the cartilage lesions and synovial inflammation. Stromelysin and collagenase activities and the collagenase messenger RNA (mRNA) level were measured in cartilage and synovial membrane. RESULTS Compared with the untreated or omeprazole-treated OA groups, the dogs treated with tenidap exhibited significant reduction in the incidence (P < or = 0.001) and size (P < or = 0.0001) of osteophytes. Tenidap also significantly decreased the size and grade of cartilage macroscopic lesions, as well as the histologic severity of cartilage lesions on both condyles and plateaus. The histologic severity of synovial inflammatory reaction was also significantly reduced (P < or = 0.003) in the tenidap group. Tenidap markedly decreased stromelysin and collagenase activity in both cartilage (stromelysin P < or = 0.003; collagenase P < or = 0.01) and synovial membrane (stromelysin P < or = 0.003; collagenase P < or = 0.005). Moreover, tenidap also decreased the collagenase mRNA level in cartilage (P < or = 0.005) and synovial membrane (P < or = 0.002). Diclofenac slightly reduced the incidence and size of osteophytes and cartilage lesions, but these changes were not statistically significant. Diclofenac had no effect on the severity of synovial inflammation, metalloprotease activity, or collagenase expression. CONCLUSION This study showed that tenidap had a more potent anti-osteoarthritic effect than diclofenac in this model. The effect of the drug in suppressing metalloprotease synthesis, a process known to play a major role in the pathophysiology of osteoarthritic lesions, may explain its mechanism of action.

Abstract
OBJECTIVE To measure serum levels of matrix metalloproteinase-1 (MMP-1), matrix metalloproteinase-3 (MMP-3), and tissue inhibitor of MMP-1 (TIMP-1) in patients with rheumatoid arthritis (RA) and in age-matched control subjects, and to determine how these correlate with serum levels of antigenic keratan sulfate (KS) and other biochemical and clinical indicators of disease activity. METHODS Immunoassays were used to measure levels of MMP-1, MMP-3, TIMP-1, and antigenic KS. Radiologic and functional joint scores were based upon Steinbrocker's criteria. Erythrocyte sedimentation rates (ESR) and levels of C-reactive proteins (CRP) were measured. RESULTS In RA patients, levels of MMP-3 and TIMP-1 were significantly increased, and strongly correlated with the ESR and CRP levels but not with radiologic or functional joint scores. Levels of antigenic KS were significantly lower in RA patients and correlated negatively with systemic parameters of inflammation and serum levels of TIMP-1. CONCLUSIONS The increase in serum levels of MMP-3 and TIMP-1 appears to reflect systemic inflammation in RA. The inverse correlation between serum levels of TIMP-1 and antigenic KS suggests that an upregulation of TIMP-1 synthesis might be responsible for the apparent suppression of cartilage aggrecan catabolism in patients with severe inflammatory changes.

Abstract
Matrix metalloproteinase 9 (MMP-9/gelatinase B) has recently been proposed to participate in the destruction of articular cartilage. Here, we report that interleukin 1 (IL-1) enhances the production of the precursor of MMP-9 in rabbit articular chondrocytes in primary culture, and this IL-1-mediated production of proMMP-9 is greatly augmented by cyclooxygenase inhibitors such as diclofenac and indomethacin, whereas the constitutive production of proMMP-2 (progelatinase A) is not modulated by IL-1 and/or cyclooxygenase inhibitors. Exogenous prostaglandin (PG) E1 and PGE2 suppress the proMMP-9 production in a dose-dependent manner. Similar results are also obtained with cultured rabbit synoviocytes. These results provide the first evidence that PGE down-regulates the production of proMMP-9 in chondrocytes and synoviocytes. Thus, cyclooxygenase inhibitors probably exert undesirable catabolic actions on the maintenance of articular cartilage under inflammatory conditions.

Abstract
Histological studies have previously demonstrated an association between mast-cell activation/degranulation and areas of connective-tissue lysis in vivo; in addition, mast-cell extracts have been shown to activate latent forms of collagenase and stromelysin. In the present study we have examined the potential roles of rat mast-cell proteinase (RMCP) I and RMCP II as activators of the precursors of matrix metalloproteinase (MMP)-1 (interstitial collagenase), MMP-2 (gelatinase A) and MMP-3 (stromelysin 1). Both RMCPs I and II activated proMMP-3 by converting the 57 kDa precursor into a 45 kDa polypeptide. The N-terminal amino acid of 45 kDa MMP-3 activated by RMCP II was identified as Phe83. By contrast, only RMCP II activated the 52 kDa proMMP-1 by converting it into a 41 kDa protein and generating the new N-termini, namely Gln80 and Val82. The collagenolytic activity which resulted from this cleavage was only 35% of the full activity, but this could not be augmented by subsequent treatment with MMP-3, the latter being a crucial enzyme for the generation of the fully active MMP-1 with Phe81 at the N-terminus, in conjunction with other serine proteinases. Thus RMCP II activates proMMP-1 via a mechanism different from that reported for the stepwise processing by combinations of other trypsin-like enzymes and MMP-3. ProMMP-2 (pro-gelatinase A) was not activated by either RMCP I or RMCP II, despite processing to smaller products.

Abstract
Eight adult periodontitis (AP) patients were studied immunohistochemically to determine the presence of matrix metalloproteinases (MMPs) MMP-1, MMP-3, and MMP-8 in the marginal gingival and gingival granulation tissue specimens obtained from periodontal flap surgery after scaling and root planing. Clinically healthy gingival tissue specimens obtained from impacted third-molar extraction operations served as controls. MMP-type-specific antisera were applied by the avidin-biotin-peroxidase complex staining method. Moderate immunoreactivity for neutrophil collagenase (MMP-8) was found both in the AP patients' marginal gingival connective tissue and in gingival granulation tissue specimens. Immunoreactivity for fibroblast-type collagenase (MMP-1) and stromelysin-1 (MMP-3) was detected only in the AP patients' gingival granulation tissue specimens. In the control specimens, no immunoreactivity for the MMPs could be detected. For the first time, this finding demonstrates immunohistochemically the presence of MMP-8 in human inflamed gingiva in situ, and further highlights the importance of MMP-8 in periodontal tissue destruction, evidently during the acute phase(s) of the disease. However, our results confirm and extend previous studies indicating that other types of MMPs from resident gingival cell sources also seem to participate in the chronic and destructive course of periodontal inflammation.

Abstract
Stromelysin levels were measured using a one-step sandwich immunoassay in synovial fluid (SF) obtained from 31 patients with rheumatoid arthritis (RA) (31 samples) and 13 patients with osteoarthritis (OA) (13 samples) and in serum from 81 patients with RA (106 samples), 12 with OA (14 samples), 12 with gouty arthritis (gout) (14 samples), and 8 with osteoporosis (OP) (14 samples) to identify differences in the levels in these diseases as well as correlations with clinical parameters in RA. SF stromelysin levels were significantly higher in RA than in OA, and rose with increasing joint destruction in the former. No significant correlations were found between the SF stromelysin level in RA and various clinical parameters, except for the volume of SF which showed a correlation. Serum levels of stromelysin were highest in RA, gout, OA, and osteoporosis in decreasing order, and in RA were correlated with the Steinbrocker Stage. A significant correlation was also found between the serum stromelysin level and number of swollen joints, and correlations with the Lansbury index, ESR, CRP, WBC and Plt. The stromelysin level in SF was thought to be a useful parameter of local joint involvement and that in serum of the severity of systemic joint inflammation.

Abstract
OBJECTIVE To compare quantitatively the in vivo expression of collagenase messenger RNA (mRNA) and stromelysin mRNA in the joint tissues of human osteoarthritis (OA) and rheumatoid arthritis (RA) patients and in two animal models of acute inflammatory arthritis. METHODS In vivo levels of metalloproteinase mRNA and protein were determined by quantitative Northern hybridization and by enzyme-linked immunosorbent assay, respectively. RESULTS In synovium, mean levels of collagenase mRNA were similar to those of stromelysin mRNA; however, in cartilage, mean levels of collagenase mRNA were significantly lower. The ratios of collagenase mRNA to stromelysin mRNA levels in RA and OA cartilage reflected similar ratios of collagenase protein to stromelysin protein levels in synovial fluid. CONCLUSION The regulation of collagenase mRNA expression in cartilage is distinct from that of stromelysin, suggesting distinct roles for these two metallo-proteinases in normal and abnormal physiologic functioning of cartilage.

Abstract
The sequence specificities of human 72-kDa fibroblast gelatinase (type IV collagenase), human 92-kDa neutrophil gelatinase (type IV collagenase), and putative metalloproteinase (PUMP or matrilysin) have been examined by measuring the rate of hydrolysis of over 50 synthetic oligopeptides covering the P4 through P4' subsites of the substrate. The peptides investigated in this paper were those employed in our previous study which systematically examined the sequence specificity of human fibroblast and neutrophil collagenases [Netzel-Arnett et al. (1991) J. Biol. Chem. 266, 6747]. The initial rate of hydrolysis of the P1-P1' bond of each peptide has been measured under first-order conditions ([S0] << KM), and kcat/KM values have been calculated from the initial rates. The specificities of these five metalloproteinases are similar, but distinct, with the largest differences occurring at subsites P1, P1', and P3'. The specificities of the two gelatinases are the most similar to each other. They tolerate only small amino acids such as Gly and Ala in subsite P1. In contrast, larger residues such as Met, Pro, Gln, and Glu are also accommodated well by PUMP. All five enzymes prefer hydrophobic, aliphatic residues in subsite P1'. PUMP exhibits a stronger preference for Leu in this subsite than is shown by the other enzymes. The P3' subsite specificities of the gelatinases and collagenases are very similar but different from those of PUMP which particularly prefers Met in this position. The specificity data from this study allow the design of optimized substrates and selective inhibitors for these metalloproteinases.

Abstract
Collagenase-tissue inhibitor of metalloproteinases-1 (TIMP-1) complex was prepared from activated collagenase and TIMP-1 purified from culture media of human skin fibroblasts. After having been confirmed to be a complex by zinc chelate chromatography, the complex was demonstrated to dissociate by passage through an anti-TIMP-1 monoclonal antibody-affinity column. On the basis of above evidence, a simple strategy was set up for the independent measurements of TIMP-1 concentration, and both active and total collagenase activities in crude culture media and body fluids.

Abstract
A one-step sandwich enzyme immunoassay (EIA) for matrix metalloproteinase 3 (MMP-3; stromelysin-1) was developed. The assay system used two simultaneous immunoreactions using a solid phase monoclonal antibody and a horseradish peroxidase-labeled monoclonal antibody (Fab'). The sensitivity of the assay system was 20 micrograms/l and linearity was obtained between 31 and 500 micrograms/l. The EIA system was capable of measuring both precursor and active forms of MMP-3 as well as the forms of MMP-3 complexed with tissue inhibitors of metalloproteinases. MMP-3 levels as measured by this assay are significantly higher in the sera of patients with rheumatoid arthritis as compared to those of healthy subjects and patients with osteoarthritis. Immunoblot analyses showed that in the sera and synovial fluids of patients with rheumatoid arthritis, MMP-3 is present in the 59- and 57-kDa precursor forms.

Abstract
OBJECTIVE In vitro studies have indicated that levels of neutral metalloproteinases in osteoarthritic (OA) cartilage are elevated and that doxycycline (doxy) inhibits collagenolytic and gelatinolytic activity in extracts of OA cartilage. The purpose of the present study was to test the effect of oral doxy administration on the severity of cartilage degeneration in OA. METHODS OA was induced in 12 adult mongrel dogs by transection of the anterior cruciate ligament (ACL) 2 weeks after dorsal root ganglionectomy. Six dogs received doxy orally from the day after ACL transection until they were killed 8 weeks later; the other 6 served as untreated OA controls. RESULTS The unstable knee of each untreated dog exhibited extensive full-thickness cartilage ulceration of the medial femoral condyle. In sharp contrast, cartilage on the distal aspect of the femoral condyle of the unstable knee was grossly normal in 2 doxy-treated dogs, and exhibited only thinning and/or surface irregularity in the others. Degenerative cartilage lesions on the medial trochlear ridge, superficial fibrillation of the medial tibial plateau, and osteophytosis were, however, unaffected by doxy treatment. Collagenolytic activity and gelatinolytic activity in cartilage extracts from OA knees of untreated dogs were 5-fold and 4-fold greater, respectively, than in extracts from dogs given doxy. CONCLUSION Prophylactic administration of doxy markedly reduced the severity of OA in weight-bearing regions of the medial femoral condyle. It remains to be determined whether administration of doxy after OA changes have developed is also effective.

Abstract
The synthesis of an 88-kDa gelatinolytic enzyme, identified as a zymogen of matrix metalloproteinase (proMMP)-9, was induced in the primary culture of rabbit articular chondrocytes by cotreatment with recombinant interleukin 1 beta (rIL-1 beta) and the protein kinase C (PKC) agonists, phorbol 12,13-dibutyrate (PDBu) or mezerein. Negligible 88-kDa gelatinolytic activity was produced by unstimulated cells or cells treated with a PKC activator alone at concentrations up to 100 ng/ml, and only a modest induction occurred with rIL-1 beta alone at concentrations of 1-100 ng/ml. However, when these cells were treated with a PKC activator in the presence of IL-1 beta (1 ng/ml), induction was striking, with enzymic activity detectable at a concentration as low as 1 ng/ml of mezerein or 10 ng/ml of PDBu. Rabbit chondrocytes in culture constitutively produced the zymogen of MMP-2 (proMMP-2) and its production was not altered by treatment with IL-1 beta or PKC agonists alone or in combination. Recombinant tumor necrosis factor alpha (rTNF alpha) did not substitute for IL-1 beta in inducing proMMP-9 in the presence of PKC activators, nor was the combination of IL-1 beta or TNF alpha alone effective. These data indicate that rabbit articular chondrocytes have a potential to synthesize and secrete proMMP-9 under certain biological and pathological conditions but that the expression of proMMP-9 is differently regulated from that of other MMPs.
