Chondroprotective effect of Alpinia oxyphylla extract in experimentally induced cartilage degradation in rabbit articular cartilage explants. J Food Biochem 2021; 45:e13713. [PMID: 33818795 DOI: 10.1111/jfbc.13713] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 03/08/2021] [Accepted: 03/15/2021] [Indexed: 11/30/2022]
Abstract
Alpinia oxyphylla is a widely used medicinal herb for diarrhea, gastralgia, tumors, hypertention, and cerebrovascular disorders. Here, we evaluated the chondroprotective effect of A. oxyphylla dried fruit ethanol extract (AOE) against cartilage degradation in rabbit articular cartilage explants. Treatment of interleukin-1α (IL-1α) and plasminogen increased degraded collagen release in culture supernatants, but pretreatment of AOE (50, 100, 200 µg/ml) inhibited the collagen release in dose-dependent manner. To examine the mechanism of action of AOE on chondroprotection, the level of matrix metalloproteinases-3 (MMP-3), matrix metalloproteinases-13 (MMP-13), tissue inhibitor of metalloprotease-1 (TIMP-1), and inflammatory mediators like prostaglandin E2 (PGE2 ) and nitric oxide (NO) was evaluated. AOE inhibited upregulation of MMP-3 and MMP-13 and downregulation of TIMP-1 and also reduced increase of PGE2 and NO level induced by exposure of IL-1α and plasminogen. These results indicate that AOE show chondroprotective effect through inhibiting collagen degradation via regulating MMPs, TIMP-1, and inflammatory mediators. PRACTICAL APPLICATIONS: Osteoarthritis (OA) is a one of the most common chronic disorders in elderly persons. Because the regenerative power of joint articular cartilage is very low, treatment of OA is difficult to expect complete recovery. Therefore, there is a need to develop a therapeutic agent that can safely and effectively inhibit the cartilage destruction. For the first time, we exhibited the inhibitory effect of AOE on collagen degradation through regulating MMPs and TIMP-1 in articular cartilage explants. These findings support AOE could be used as herbal therapeutic application for protecting articular cartilage to prevent OA.

Abstract
Mechanical stimuli play important roles in proliferation and differentiation of connective tissue cells, and development and homeostatic maintenance of tissues. However, excessive mechanical loading to a tissue can injure cells and disrupt the matrix, as occurs in tendinopathy. Tendinopathy is a common clinical problem in athletes and in many occupational settings due to overuse of the tendon. Moreover, interleukin (IL)-1β is generally considered to be a "bad" cytokine, activating NF-κb and cell death and inducing matrix metalloproteinase (MMPs 1, 2, 3) expression and matrix destruction. However, activated NF-κB can also drive a cell survival pathway. We have reported that cyclic strain induced tenocyte death in three-dimensional (3D) cultures, and IL-1β could promote cell survival under strain. Therefore, it was hypothesized that 1) cyclic strain could induce cell death in tenocytes as observed in pathologic tendons in vivo; 2) a gene expression profile indicative of tendinopathy could be identified; and 3) low-dose IL-1β could protect cells from strain-induced, tendinopathy-like changes. Human tenocytes were cultured in 3D type I collagen hydrogels and subjected to 3.5% elongation at 1 Hz for 1 h/day for up to 5 days with or without IL-1β. Real-time RT-PCR data showed that cyclic strain regulated the expression of tendinopathy marker genes in a manner similar to that found in pathological tendons from patients and that addition of IL-1β reversed the gene expression changes to control levels. Results of further studies showed that IL-1β may modulate cell survival through upregulating the expression of connexin 43, which is involved in the modulation of cell death/survival in a variety of cells and tissues. The elucidation of the mechanisms underlying strain-induced cell death and recovery from strain injury will facilitate our understanding of the pathogenesis of tendinopathy and may lead to the discovery of new molecular targets for early diagnosis and treatment of tendinopathy.

Abstract
Matrix metalloproteinases (MMPs) have been linked to the metastatic potential of tumor cells due to their ability to degrade the extracellular matrix. MMP-3 (stromelysin-1) is upregulated in a wide variety of human tumors. We used the MMTV-PyMT breast cancer model to determine if MMP-3 is involved in tumorigenesis and metastatic growth. In this model the stromal expression of MMP-3 mRNA resembles the predominant MMP-3 expression pattern observed in human ductal breast carcinomas. We studied a cohort of 63 PyMT transgenic mice, either deficient for MMP-3 or wild-type controls. The degree of metastasis did not differ significantly between the two groups of mice, although the median lung metastasis volume was more than threefold increased in MMTV-PyMT mice deficient in MMP-3. Likewise, primary tumor growth rate and lymph node metastasis were not significantly affected by MMP-3-deficiency. By comparing mRNA levels in MMP-3-deficient PyMT tumors with PyMT wild-type tumors we excluded compensatory transcriptional changes of other MMPs or their specific inhibitors. Thus, we conclude that genetic ablation of MMP-3 does not significantly affect tumor growth and metastasis in the MMTV-PyMT model.

Inhibition of matrix metalloproteinases enhances in vitro repair of the meniscus. Clin Orthop Relat Res 2009; 467:1557-67.

Abstract
Damage or injury of the meniscus is associated with onset and progression of knee osteoarthritis (OA). The intrinsic repair capacity of the meniscus is inhibited by inflammatory cytokines, such as interleukin-1 (IL-1). Using an in vitro meniscal repair model system, we examined the hypothesis that inhibition of matrix metalloproteinases (MMPs) in the presence of IL-1 will enhance repair of meniscal lesions. Integrative repair of the meniscus was examined between two concentric explants cultured with IL-1 and various MMP inhibitors for 14 days. Throughout the culture period, we assessed total specific MMP activity in the media. At harvest, biomechanical testing to assess the strength of repair and histologic staining were performed. IL-1 decreased the shear strength of repair, as compared with control explants. In the presence of IL-1, the broad-spectrum MMP inhibitor GM 6001 decreased the MMP activity in the media, increased the shear strength of repair, and enhanced tissue repair in the interface. However, individual MMP inhibitors did not alter the shear strength of repair in either the presence or absence of IL-1. These findings suggest IL-1 may inhibit meniscal repair through upregulation of MMPs, but inhibition of multiple MMPs may be necessary to promote integrative meniscal repair.

Abstract
BACKGROUND The advanced glycation end products (AGEs) accumulate in joints of osteoarthritis patients. This study aimed to investigate the roles of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) pathways in AGE-mediated cartilage damage. MATERIALS AND METHODS Methylglyoxal-modified albumin was used as the source of AGE. Porcine and human chondrocytes were prepared from the joint cartilage of pigs and osteoarthritis patients. The activation of COX-2, iNOS, nuclear factor-kappaB (NF-kappaB), activator protein-1 (AP-1) and protein kinases was determined by Western blotting, kinase assay, electrophoretic mobility shift assay (EMSA) or transfection assay. Prostaglandin E(2) (PGE(2)) and NO concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and Griess reaction respectively. The enzymatic activity of COX was determined by measuring the conversion of arachidonic acid to PGE(2). The release of sulphated glycosaminoglycan and the intensity of Safranin O staining were used to measure cartilage degradation. RESULTS AGE potently induced COX-2-PGE(2) and iNOS-NO activation in porcine and human chondrocytes. Meanwhile, the upstream molecules regulating COX-2/iNOS activation, such as AP-1, NF-kappaB, extracellular signal regulated protein kinase (ERK) and c-jun N-terminal kinase (JNK), were activated by AGE. Although AGE could not activate p38 directly, by measuring COX enzyme activity, the inhibition of p38 resulted in suppressing AGE-induced conversion of arachidonic acid to PGE(2). Furthermore, successful blockage of either COX-2 or NOS activity significantly reduced AGE-mediated proteoglycan release and cartilage degradation. CONCLUSIONS This study highlights the significance of COX-2 and iNOS pathways in AGE-mediated OA pathogenesis and their potential as therapeutic targets that are beyond pain killing for OA treatment.

Abstract
AIM Levels of interleukin-1alpha (IL-1alpha) are elevated in periodontal inflammation. IL-1A gene polymorphisms are associated with inflammatory diseases. This study aimed to investigate IL-1A gene polymorphism in Cyclosporin A (CsA)-treated renal transplant patients and investigate the association between this polymorphism and gingival crevicular fluid (GCF) levels of several cytokines. MATERIALS AND METHODS Fifty-one renal transplant patients on CsA treatment (25 with and 26 without gingival overgrowth) and 29 healthy controls were recruited for the study. Demographic, pharmacological and periodontal parameters were recorded and gingival overgrowth was assessed. RESULTS Multiple regression analysis showed that genotype was significantly associated with gingival overgrowth (p=0.02). Carriage of the IL-1A (-889) T allele was strongly protective [95% confidence interval (CI): 0.046-0.77], although not significantly associated with IL-1alpha protein levels in GCF. IL-1alpha, IL-1beta and IL-8, but not IL-6, were detected in GCF of CsA-treated patients, but none of them was significantly associated with gingival overgrowth. CONCLUSIONS This study is the first to associate a gene polymorphism as a risk factor for CsA-induced gingival overgrowth in renal transplant patients, demonstrating that IL-1A polymorphism might alter individual susceptibility to CsA. However, there was no association between GCF cytokine levels and the presence of gingival overgrowth or patient IL-1A genotype.

Abstract
This study investigated the effects of two highly sulfated polysaccharides, calcium pentosan polysulfate and heparin, on the loss of newly synthesized proteoglycans from the matrix of explant cultures of bovine tendon. The tensional region of deep flexor tendon was incubated with [35S]sulfate for 6 h and then placed in culture for up to 15 days. The amount of radiolabel associated with proteoglycans lost to the medium and retained in the matrix was determined for each day in culture. It was shown that both sulfated polysaccharides at concentrations of 1000 microg x mL(-1) inhibited the loss of 35S-labeled large and small proteoglycans from the matrix and concomitant with this was a retention of chemical levels of proteoglycans in the explant cultures. In other explant cultures that were maintained in culture in the presence of both agents for more than 5 days after incubation with [35S]sulfate, inhibition of the intracellular catabolic pathway was evident, indicating that these highly sulfated polysaccharides also interfered with the intracellular uptake of small proteoglycans by tendon cells.

Abstract
Articular cartilage is a potential target for drugs designed to inhibit the activity of matrix metalloproteinases (MMPs) to stop or slow the destruction of proteoglycan and collagen in the cartilage extracellular matrix. The purpose of this study was to investigate the effects of Betula platyphylla var. japonica on inhibiting the release of glycosaminoglycan (GAG), the degradation of collagen, and MMP expression and activity in rabbit articular cartilage explants. Interleukin-1alpha (IL-1alpha) rapidly induced GAG, but collagen was much less readily released from cartilage explants. Betula platyphylla var. japonica significantly inhibited GAG and collagen release in a concentration-dependent manner. Betula platyphylla var. japonica dose-dependently inhibited MMP-3 and MMP-13 expression and activities from IL-1alpha-treated cartilage explant culture when tested at concentrations ranging from 0.02 to 0.2 mg/ml. Betula platyphylla var. japonica had no harmful effect on chondrocyte viability or cartilage morphology in cartilage explants. Histological analysis indicated that Betula platyphylla var. japonica reduced the degradation of the cartilage matrix compared with that of IL-1alpha-treated cartilage explants. These results indicate that Betula platyphylla var. japonica inhibits the degradation of proteoglycan and collagen through the down regulation of MMP-3 and MMP-13 expression and activities without affecting the viability or morphology of IL-1alpha-stimulated rabbit articular cartilage explants.

Abstract
SKI306X was previously found to have cartilage protective effects in the experimental osteoarthritis (OA) model. To investigate the chondro-protective benefits of SKI306X for its capacity in altering changes in cartilage metabolism and molecular mechanisms of cartilage protective action, SKI306X is studied in rabbit cartilage explants culture. To investigate the protective effect of SKI306X on cartilage catabolism, we assessed collagen degradation in rabbit cartilage explants treated with interleukin-1alpha up to 3 weeks. To examine the reaction mechanism, matrix metalloproteinase (MMPs) were investigated by fluorimetric and Western blotting analysis. In addition, its effects on the activation process of proenzyme MMP-3 were determined by gelatin zymography. SKI306X significantly inhibited collagen degradation and inhibited the activities of several MMPs. Total MMPs activities in cultured medium were substantially increased in the third week at the time of collagen degradation with the absence of SKI306. However, the introduction of SKI306X decreased MMPs activities in cultured medium. Furthermore, Western blotting analysis proved that these inhibitory effects of this drug were the result of inhibiting MMPs expression. SKI306X also inhibited the activation of proenzyme MMP-3 to the active form of MMP-3. These results indicate that SKI306X inhibits matrix degradation by down regulating MMPs expression and secretion, inhibition of MMPs activity, and inhibiting activation of MMP-3 during the collagen breakdown process.

Abstract
Heparinoid is one of the major contents of Mobilat widely used as an antirheumatic drug. To clarify the precise mechanisms of the antirheumatic effect of heparinoid, we investigated its effects on the production of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) from rheumatoid synovial fibroblasts stimulated (or not) with interleukin-1 alpha (IL-1alpha) at 100 units mL(-1). The expression of TIMP-3 mRNA was also investigated in a similar manner. The production of both MMPs and TIMPs and the expression of TIMP-3 mRNA were investigated by western-blot analysis and northern-blot hybridization, respectively. Under the stimulation of IL-1alpha, heparinoid increased the production of TIMP-3 in a concentration-dependent manner, but not TIMP-1, TIMP-2, MMP-1 or MMP-3. Heparinoid did not affect the expression of TIMP-3 mRNA that was increased by the stimulation of IL-1alpha. These findings suggest that the anti-rheumatoid effect of heparinoid may be due to increased production of TIMP-3. This increase in TIMP-3 may help redress the imbalance between the amounts of MMPs and TIMPs as observed in the joint tissues of rheumatoid arthritis and osteoarthritis patients.

Abstract
OBJECTIVE Bovine and human cartilages in explant culture respond to proinflammatory cytokines with the up-regulation of procollagenases. In stimulated bovine nasal cartilage (BNC), >90% of collagen is released by day 14 of culture, but collagen release is rarely seen before day 7. The aim of this study was to investigate if activation of procollagenases is a rate-limiting step in cartilage collagen breakdown. METHODS BNC and human articular cartilage explants were cultured with interleukin-1alpha (IL-1alpha) and/or oncostatin M (OSM) with or without test reagents. Collagen levels were determined by assay of hydroxyproline. Collagenase activity was measured using the diffuse fibril assay. RESULTS The addition of procollagenase activators, matrix metalloproteinase 3 (MMP-3), and APMA to IL-1alpha/OSM-stimulated BNC resulted in early release of collagen. The release with APMA was completely blocked by the addition of tissue inhibitor of metalloproteinases 1. This shows that procollagenases are present early in the culture period, but cartilage collagen breakdown does not happen until activation occurs. The addition of plasminogen to IL-1alpha/OSM-stimulated cartilage produced early collagen release in bovine and a significant increase in human cartilage. Thus, plasminogen activators (PAs) are present and convert plasminogen to plasmin, a known activator of several MMPs, including collagenases. Addition of alpha1-proteinase inhibitor or a urokinase-type PA inhibitor, 7-amino-4-chloro-3-(3-isothiureidopropoxy) isocoumarin, partially blocked the breakdown of collagen from IL-1alpha/OSM-treated bovine cartilage. This suggests that serine proteinases are involved in the activation cascades of procollagenases that result in cartilage collagen breakdown. CONCLUSION The activation of procollagenases is a key control point in cartilage collagen breakdown, and serine proteinase pathways activate MMPs.

Abstract
Ceramide participates in signal transduction of IL-1 and TNF, two cytokines likely involved in cartilage degradation in osteoarthritis. We previously showed that ceramide stimulates proteoglycan degradation, mRNA expression of matrix metalloproteinase (MMP)-1, -3, and -13, and pro-MMP-3 production in rabbit cartilage. Since aggrecan, the main cartilage proteoglycan, can be cleaved by metalloproteinases both of MMP and aggrecanase type, the aim of this study was to determine if ceramide stimulates aggrecanase action and, if that is the case, in which measure aggrecanase mediates the degradative effect of ceramide. To this end, antibodies were used against the C terminal aggrecan neoepitopes generated by aggrecanases (NITEGE(373)) and MMPs (DIPEN(341)). Ceramide C(2) at 10(-5) to 10(-4) M dose-dependently increased NITEGE signal, without changing that of DIPEN, in cultured explants of rabbit cartilage. The effects of 10(-4) M C(2) on NITEGE signal and proteoglycan degradation were similarly antagonized by the metalloproteinase inhibitor batimastat, with return to the basal level at 10(-6) M. These results show that, similarly to IL-1 and TNF, ceramide-induced aggrecan degradation is mainly due to aggrecanases. That no increase of MMP activity was detected, despite stimulation of MMP expression, was probably due to lack of proenzyme conversion to mature form, since addition of a MMP activator to C(2)-treated cartilage increased both DIPEN signal and proteoglycan degradation. These findings support the hypothesis that cytokine-induced ceramide could play a mediatory role in situations of increased degradation of cartilage matrix.

Abstract
OBJECTIVE To assess the role of matrix metalloproteinases (MMPs) in cartilage and bone erosions in Lyme arthritis METHODS We examined synovial fluid from 10 patients with Lyme arthritis for the presence of MMP-2, MMP-3, MMP-9, and "aggrecanase" activity using gelatinolytic zymography and immunoblot analysis. We developed an in vitro model of Lyme arthritis using cartilage explants and observed changes in cartilage degradation in the presence of Borrelia burgdorferi and/or various protease inhibitors. RESULTS Synovial fluid from patients with Lyme arthritis was found to contain at least 3 MMPs: gelatinase A (MMP-2), stromelysin (MMP-3), and gelatinase B (MMP-9). In addition, there was evidence in 2 patients of "aggrecanase" activity not accounted for by the above enzymes. Infection of cartilage explants with B. burgdorferi resulted in induction of MMP-3, MMP-9, and "aggrecanase" activity. Increased induction of these enzymes by B. burgdorferi alone was not sufficient to cause cartilage destruction in the explants as measured by glycosaminoglycan (GAG) and hydroxyproline release. However, addition of plasminogen, which can act as an MMP activator, to cultures resulted in significant GAG and hydroxyproline release in the presence of B. burgdorferi. The MMP inhibitor batimastat significantly reduced the GAG release and completely inhibited the collagen degradation. CONCLUSION MMPs are found in synovial fluids from patients with Lyme arthritis and are induced from cartilage tissue by the presence of B. burgdorferi. Inhibition of MMP activity prevents B. burgdorferi-induced cartilage degradation in vitro.

Abstract
Abnormal mechanical loading of joints may induce degeneration of articular cartilage. Shear stress is one mode of mechanical loading that may regulate chondrocyte metabolism. We investigated the mechanism by which shear stress induces the gene encoding matrix metalloproteinase-9, a mediator of the progressive degradation of articular cartilage in osteoarthritis. In vitro experiments using passaged rabbit chondrocytes in monolayer culture subjected to a shear stress of 16 dyn/cm2 (1.6 Pa) in a flow channel showed increased expression of the matrix metalloproteinase-9 gene. The induction of matrix metalloproteinase-9 appeared to depend on a region in the 5' promoter of the gene that contains a 12-0-tetradecanoylphorbol 13-acetate-responsive element. Transfection experiments using a construct containing a luciferase reporter driven by a 12-0-tetradecanoylphorbol 13-acetate-responsive element indicated that shear stress activated a 12-0-tetradecanoylphorbol 13-acetate-responsive element-mediated transcription in chondrocytes. Similar experiments showed that shear stress induced a matrix metalloproteinase-9 promoter construct (matrix metalloproteinase-9-luciferase). Shear stress activated c-Jun NH2-terminal kinase, extracellular signal-regulated kinase, and p38. Transfection of matrix metalloproteinase-9-luciferase together with the dominant negative mutant of c-Jun NH2-terminal kinase, but not with that of extracellular signal-regulated kinase or p38, attenuated the shear-induced matrix metalloproteinase-9 promoter activity. In addition, transfection of constructs encoding dominant negative mutants of Ras, Rac, and Cdc42 attenuated the induction of c-Jun transcriptional activity by shear stress. Thus. shear stimulation of chondrocytes stimulates Ras, Rac, and Cdc42, which subsequently activate c-Jun NH2-terminal kinase to induce a 12-0-tetradecanoylphorbol 13-acetate-responsive element-mediated expression of matrix metalloproteinase-9.

Abstract
OBJECTIVE Joint destruction in rheumatoid arthritis (RA) is a result of degradation and invasion of the articular cartilage by the pannus tissue. The present study was undertaken to examine the role of the plasminogen activation system in cartilage degradation and invasion by synovial fibroblasts and investigate a novel gene therapeutic approach using a cell surface-targeted plasmin inhibitor (ATF.BPTI). METHODS Adenoviral vectors were used for gene transfer. The effects of ATF.BPTI gene transfer on RA synovial fibroblast-dependent cartilage degradation were studied in vitro, and cartilage invasion was studied in vivo in the SCID mouse coimplantation model. RESULTS The results indicate that cartilage matrix degradation by rheumatoid synovial fibroblasts is plasmin mediated and depends on urokinase-type plasminogen activator for activation. Targeting plasmin inhibition to the cell surface of the fibroblasts by gene transfer of a cell surface-binding plasmin inhibitor resulted in a significant reduction of cartilage matrix degradation in vitro and of cartilage invasion in vivo. Compared with uninfected rheumatoid synovial fibroblasts, the mean +/-SEM cartilage degradation in vitro was reduced to 87.9+/-0.9% after LacZ gene transfer versus a reduction to 24.0+/-1.6% after ATF.BPTI gene transfer (P<0.0001). The mean +/- SEM in vivo cartilage invasion score was 3.1+/-0.4 in the control-transduced fibroblasts and 1.8+/-0.4 in the ATF.BPTI-transduced fibroblasts (P<0.05). CONCLUSION These results indicate a role of the plasminogen activation system in synovial fibroblast-dependent cartilage degradation and invasion in RA, and demonstrate an effective way to inhibit this by gene transfer of a cell surface-targeted plasmin inhibitor.

Abstract
The extra domain-A (EDA), present in fibronectin (FN) molecules arising from alternatively spliced transcripts, appears only during specific biological and pathogenic processes. However, its function is poorly understood. To define the physiologic role of this domain in joint connective tissue, the biological effects on rabbit cartilage explants, chondrocytes, and synovial cells were studied. A recombinant EDA protein (rEDA) increased proteoglycan release (3. 6-fold) in cartilage explant cultures and markedly induced production of matrix metalloproteinase (MMP)-1 in chondrocytes. In addition, rEDA induced MMP-1, MMP-3, and MMP-9 in synovial cells. These effects were elicited only by rEDA, while its neighboring type III repeats, III(11) or III(12), scarcely had any such effects. Interestingly, reorganization of F-actin stress fibers accompanied MMP-1 expression in synovial cells treated with rEDA, suggesting alteration of cellular phenotype. Subsequent Northern blotting revealed expression of pro-inflammatory cytokines, including interleukin (IL)-1alpha and IL-1beta, was induced by rEDA prior to MMP-1 expression. Delayed MMP-1 expression suggests that rEDA-induced IL-1s promote MMP-1 expression in an autocrine manner. This hypothesis is supported by the reduction of EDA-induced MMP-1 production by IL-1 receptor antagonist. The effect of EDA on MMP-1 production was reduced by connection with an adjacent type III repeat on either the NH(2) or COOH side of EDA and was abolished by connection on both sides of EDA, suggesting that exposure of either the NH(2) or COOH terminus of EDA domain by proteolytic cleavage releases the inducing activity. In agreement with these results, full-length cellular FN did not induce MMP-1 production. Furthermore, a 160-kDa EDA-positive FN fragment, which was purified from human placental tissue and corresponds to the region from NH(2) terminus through the EDA, induced MMP-1 production. Taken together, these results suggest that the EDA in FN fragments triggers alterations of cell physiology and plays a role in matrix degradation in joint connective tissue.

Abstract
OBJECTIVE Murine antigen induced arthritis (AIA) is a chronic, smouldering inflammation. Flares of arthritis can be induced by antigen rechallenge or exposure to inflammatory mediators like interleukin 1 (IL1). These flares are characterised by a fast and marked proteoglycan (PG) depletion if compared with the initial arthritis. This study investigated the involvement of metalloproteinases in both the initial and the flare phase of arthritis. METHODS Murine AIA was induced and a flare up of arthritis was induced by injection of 10 ng of IL1beta. Messenger RNA levels of MMP-1 and -3 were studied by RT-PCR. MMP activity in cartilage, during both primary AIA as well as the flare up of arthritis, was studied by immunodetection of MMP specific neoepitopes in aggrecan (VDIPEN). Cartilage just before flare induction was analysed for presence of MMPs at the mRNA level as well as at the protein level by zymography. RESULTS At the onset of AIA, a fast upregulation of mRNA for stromelysin and collagenase was noted. However, no VDIPEN epitopes were detected during this early phase of arthritis. They appeared when PG depletion was severe at day 7 of arthritis and disappeared when cartilage was repaired. IL1 injection into a knee joint at week 4 of AIA caused a flare up of arthritis, coinciding with a fast and marked PG degradation. This degradation was characterised by accelerated expression of VDIPEN epitopes if compared with the expression in primary AIA. Analysis of cartilage at week 4 of AIA showed still increased mRNA levels of MMP-1 and -3. Moreover, increased levels of latent MMPs were present as well, as APMA activation induced profound VDIPEN epitope. In vitro exposure to IL1 did show increased PG breakdown but no VDIPEN expression, suggesting that factors in addition to IL1 are needed to cause the in vivo VDIPEN expression. CONCLUSIONS The fast and marked PG depletion seen in a flare up of AIA coincides with accelarated expression of MMP induced neoepitopes compared with expression during primary AIA. This accelerated expression is probably linked to increased levels of latent enzyme, which were found to be present in the cartilage before induction of a flare up.

Abstract
Degradation of extracellular matrix (ECM) proteins in the aorta is a critical step for the development of atherosclerosis. Expression of matrix metalloproteinase (MMP)-12 (macrophage elastase), an elastin-degrading proteinase in the MMP family, was investigated in the thoracic aorta of rabbits fed a 1% cholesterol-containing diet for 16 weeks. In the atherosclerotic lesions, MMP-12 was produced abundantly at both the mRNA and protein levels, whereas no expression was observed in the normal rabbit aortas. The principal source of MMP-12 was macrophage foam cells (MFCs) that had infiltrated the atherosclerotic intima; this was demonstrated in both in vitro culture studies of MFCs purified from atherosclerotic lesions and immunohistochemical studies of aortic lesions. Additional biochemical studies using recombinant rabbit MMP-12 revealed that MMP-12 digested elastin, type IV collagen, and fibronectin and also activated MMP-2 and MMP-3. Expression of MMP-12 by human macrophage cell lines was increased by stimulation with acetylated low-density lipoprotein, implying augmentation of MMP-12 production during foam cell formation. Increased expression of MMP-12 in atherosclerotic lesions, concomitant with foam cell generation, which triggers the acceleration of ECM breakdown, is likely to be a critical step in the initiation and progression of the atherosclerotic cascade.

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.
