Abstract
OBJECTIVE Degradation of the collagenous extracellular matrix by metalloproteases (MMPs) plays an important role in the pathogenesis of osteoarthritis (OA). Recently, it was suggested that endothelin 1 (ET-1), a potent vasoconstrictor, may be involved in MMP regulation. This study investigated the role of ET-1 in OA cartilage degradation. METHODS We explored ET-1 expression and synthesis in normal and OA cartilage and synovial membrane by reverse transcription-polymerase chain reaction and immunohistochemistry. MMP-1 and MMP-13 gene expression and protein synthesis were investigated using Northern blotting and enzyme-linked immunosorbent assays. Additionally, ET-1-induced collagenase activity, type II collagen metabolites, and tissue inhibitor of metalloproteases 1 (TIMP-1) protein were evaluated. RESULTS We found expression and synthesis of ET-1, in situ, in both normal and OA cartilage and synovial membrane. We demonstrated that ET-1 induced gene expression and protein synthesis of both MMP-1 and MMP-13. These enzymes were produced in OA chondrocyte cultures, and the production increased in a dose-dependent manner in the presence of ET-1. In OA cartilage, ET-1 also induced type II collagen-derived neoepitopes concomitantly with an increase in collagenase activity and a decrease in TIMP-1 protein. CONCLUSION Our results provide strong evidence of the catabolic role of ET-1 in OA cartilage via MMP-1 and MMP-13 up-regulation. As well, ET-1 increased the net MMP/TIMP balance and secondarily increased collagen degradation. Hence, ET-1 becomes an attractive factor to target in the conception of new therapeutic approaches for OA and other diseases in which MMP-13 and MMP-1 actions are crucial in tissue alteration.

Abstract
OBJECTIVE Chondromodulin-I (ChM-I), a cartilage derived anti-angiogenic factor, has been shown to regulate the vascular invasion during endochondral bone formation. We evaluated the expression and localization of ChM-I in articular cartilage during the progression of osteoarthritis (OA) in the rat, and correlated ChM-I expression with the increase in vascular invasion into OA articular cartilage. METHODS Expression of ChM-I, type II collagen, basic fibroblast growth factor, vascular endothelial growth factor (VEGF), and matrix metalloproteinases MMP-9 and MMP-13 were examined in articular cartilage of intact growing and adult rats and in the surgically induced OA model using in situ hybridization, Western blot analysis, and immunohistochemistry. Co-immunostaining for ChM-I and CD-31 was performed to localize ChM-I and neovascularization in articular cartilage at advanced stage of OA. RESULTS Abundant expression of ChM-I protein was detected in avascular regions of the developing and adult healthy articular cartilage. In early OA, ChM-I expression decreased in the superficial zone of articular cartilage, while levels of proteoglycan and type II collagen were comparable to control. In advanced OA, ChM-I expression was reduced in all zones of articular cartilage, and the number of VEGF-expressing cells was increased. Immunohistochemical studies showed that vascular invasion occurred in proximity to chondrocytes with high expression of pro-angiogenic markers, and decreased expression of ChM-I. CONCLUSION High expression of ChM-I was detected in articular cartilage of growing and normal adult joints, implicating its role in the maintenance of avascularity of intact articular cartilage. Expression of ChM-I decreased, while expression of VEGF and other pro-angiogenic factors increased, in OA cartilage. These findings suggest the loss of ChM-I from articular cartilage might be responsible in part for promoting blood vessel invasion into the cartilage during progression of OA.

Abstract
Collagenase-3 (matrix metalloproteinase 13, MMP-13) was employed as a surrogate marker to compare the characteristics of incisional wound repair after surgery with the free-electron laser at 6.1 microm and the scalpel. Using a transgenic mouse strain with the MMP-13 or the COL1A2 promoter driving luciferase expression, we observed MMP-13 and COL1A2 expression, tensile strength, macrophage infiltration, and wound histology for up to 62 d. The scalpel incisions showed higher tensile strength than free-electron laser wounds from days 10 to 22 postwounding, despite minimal collateral thermal damage. After 45 d healing was similar. Trichrome staining confirmed that the scalpel incisions had more dense collagen deposition than free-electron laser incisions up to 36 d postinjury, but at day 45 they became similar. MMP-13 expression was biphasic, with peak activities at days 15 and 37 after injury, whereas free-electron laser wounds showed greater luciferase activity than scalpel wounds. Peak COL1A2 activity preceded the MMP-13 maximum. MMP-13 expression localized predominantly to dermal fibroblasts near the epidermis at day 15, and in the region of the deep dermis, muscle, and fascia at day 37 postwounding. Migrating muscle cells, but not all skeletal muscle cells, also expressed MMP-13. Free-electron laser incisions contained more macrophages than scalpel wounds at days 2 and 7 postinjury, suggesting that free-electron laser irradiation exacerbated the inflammatory response and thereby stimulated MMP-13 expression. These results revealed that MMP-13 was involved in a series of coordinated events during wound healing, not only the long-term remodeling of wound connective tissue, but also skeletal muscle repair. MMP-13 activity in vivo may correlate with the extent of tissue damage.

Abstract
Endochondral ossification is regulated by many factors, including mechanical stimuli, which can suppress or accelerate chondrocyte maturation. Mathematical models of endochondral ossification have suggested that tension (or shear stress) can accelerate the formation of endochondral bone, while hydrostatic stress preserves the cartilage phenotype. The goal of this study was to test this hypothesis by examining the expression of hypertrophic chondrocyte markers (transcription factor Cbfa1, MMP-13, type X collagen, VEGF, CTGF) and cartilage matrix proteins under cyclic tension and cyclic hydrostatic pressure. Chondrocyte-seeded alginate constructs were exposed to one of the two loading modes for a period of 3 h per day for 3 days. Gene expression was analyzed using real-time RT-PCR. Cyclic tension upregulated the expression of Cbfa1, MMP-13, CTGF, type X collagen and VEGF and downregulated the expression of TIMP-1. Cyclic tension also upregulated the expression of type 2 collagen, COMP and lubricin, but did not change the expression of SOX9 and aggrecan. Cyclic hydrostatic pressure downregulated the expression of MMP-13 and type I collagen and upregulated expression of TIMP-1 compared to the unloaded controls. Hydrostatic pressure may slow chondrocyte differentiation and have a chondroprotective, anti-angiogenic influence on cartilage tissue. Our results suggest that cyclic tension activates the Cbfa1/MMP-13 pathway and increases the expression of terminal differentiation hypertrophic markers. Mammalian chondrocytes appear to have evolved complex mechanoresponsive mechanisms, the effects of which can be observed in the histomorphologic establishment of the cartilaginous skeleton during development and maturation.

Abstract
Matrix metalloproteinases (MMPs) that have a proteolytic activity against the components of extracellular matrix (ECM) play an important role in the invasive and metastatic spread of tumors. The role of MMPs and tissue inhibitors of MMPs (TIMPs) in laryngeal squamous cell carcinoma (LSCC) has not been elucidated sufficiently. The aim of the present study was to evaluate the correlation between the expression of collagenase-1 (MMP-1), collagenase-3 (MMP-13) and TIMP-1, as well as the clinicopathological features of LSCCs. The expression of collagenases and TIMP-1 was examined immunohistochemically in 50 cases of surgically obtained specimens of primary LSCCs. Analyses indicated that LSCC cells as well as stromal cells expressed MMP-1, MMP-13 and TIMP-1 immunostaining. Overexpression of TIMP-1 occurred more frequently in non-metastasizing cases (P=0.009). TIMP-1 and MMP-1 staining correlated significantly with the histologic type of LSCC. The keratinizing type of carcinomas exhibited higher TIMP-1 protein expression than the nonkeratinizing variety (P=0.01). TIMP-1 staining was associated with the grade of differentiation, since it was found predominantly in well and moderately differentiated carcinomas (P=0.04). The findings confirm that expression of analyzed MMPs and TIMP-1 is characteristic of LSCC and that these enzymes contribute to the progression of tumors. TIMP-1 upregulation might exhibit lower metastatic potential in LSCCs and is linked rather with an early stage of tumor progression. It seems also that TIMP-1 expression is dependent on the grade of differentiation.

Abstract
Inhibitors of matrix metalloprotease (MMP)-13 and tumor necrosis factor-alpha converting enzyme (TACE) have been highly sought as potential therapeutic agents for the treatment of osteoarthritis and rheumatoid arthritis, respectively. This review focuses on the published literature on these inhibitors from 2001 to mid-2003. Significant advances have been reported in the design and synthesis of potent and selective inhibitors of MMP-13 using hydroxamic acid and non-hydroxamate zinc chelators on a variety of scaffolds. TACE inhibitors based on variations of known MMP inhibitors scaffolds and novel designs have been reported. Selectivity profiles for these inhibitors range from broad-spectrum to TACE-specific. Future clinical studies on these and other inhibitors will determine which MMP, or set of MMPs, must be inhibited for efficacy and long-term safety.

Abstract
Hydrogels composed of N-isopropylacrylamide (NIPAAm) and acrylic acid (AAc) were prepared by redox polymerization with peptide cross-linkers to create an artificial extracellular matrix (ECM) amenable for testing hypotheses regarding cell proliferation and migration in three dimensions. Peptide degradable cross-linkers were synthesized by the acrylation of the amine groups of glutamine and lysine residues within peptide sequences potentially cleavable by matrix metalloproteinases synthesized by mammalian cells (e.g., osteoblasts). With the peptide cross-linker, loosely cross-linked poly(N-isopropylacrylamide-co-acrylic acid) [P(NIPAAm-co-AAc)] hydrogels were prepared, and their phase transition behavior, lower critical solution temperature (LCST), water content, and enzymatic degradation properties were investigated. The peptide-cross-linked P(NIPAAm-co-AAc) hydrogels were pliable and fluidlike at room temperature and could be injected through a small-diameter aperture. The LCST of peptide-cross-linked hydrogel was influenced by the monomer ratio of NIPAAm/AAc but not by cross-linking density within the polymer network. A peptide-cross-linked hydrogel with a 97/3 molar ratio of NIPAAm/AAc exhibited a LCST of approximately 34.5 degrees C. Swelling was influenced by NIPAAm/AAc monomer ratio, cross-linking density, and swelling media; however, all hydrogels maintained more than 90% water even at 37 degrees C. In enzymatic degradation studies, breakdown of the peptide-cross-linked P(NIPAAm-co-AAc) hydrogels was dependent on both the concentration of collagenase and the cross-linking density. These results suggest that peptide-cross-linked P(NIPAAm-co-AAc) hydrogels can be tailored to create environmentally-responsive artificial extracellular matrixes that are degraded by proteases.

Abstract
BACKGROUND AND PURPOSE The goal of this study was to determine the temporal profile of several matrix metalloproteinases (MMPs), tissue inhibitors of MMPs (TIMPs), and laminin (an MMP substrate) in human stroke under different treatment paradigms, including thrombolysis and hypothermia. METHODS We serially measured the serum levels of MMP-2, MMP-3, MMP-9, MMP-13, TIMP-1, TIMP-2, and laminin in 50 patients with acute ischemic stroke using zymography or enzyme-linked immunosorbent assay. Patients were treated with heparin, therapeutic thrombolysis, or hypothermia. Scandinavian Stroke Scale scores were obtained at baseline. Infarct volume was measured with CT scanning on day 4 after stroke onset. Healthy persons were used as control subjects. RESULTS MMP-2 and MMP-9 increased during the course of ischemia, whereas intact laminin and TIMP-2 decreased significantly (P<0.05). MMP-9 and laminin levels varied significantly by infarct size (P=0.001) and therapy (P=0.0005). MMP-9 levels were significantly higher in patients treated with tissue plasminogen activator (tPA) compared with patients treated with hypothermia. The cleaved form of MMP-9 was found solely in 4 patients treated with tPA. Intact laminin levels were significantly lower in the tPA group than in the hypothermia group. CONCLUSIONS Selected MMPs and TIMPs are involved in the pathophysiology of acute stroke. This is also reflected by changes in laminin. Treatment paradigms differentially influence levels of MMP-9 and laminin. Combination therapies explicitly involving MMP inhibition could be of value in future treatment strategies.

Abstract
MMP-13 appears to be one of the most important MMPs in cartilage remodeling and mineralization, because it exhibits a substrate preference for the cartilage-specific type II collagen. The condylar process is constructed by rapid accumulation of hypertrophic chondrocytes during development, but its mechanism is still unclear. To investigate the role of MMP-13 in developing condylar cartilage, we immunohistochemically examined the localization of MMP-13 in the endochondral ossification of the mandibular condyle and tibiae of newborn mice. In the tibiae, the MMP-13 expression was detected only in the deepest layer of the terminal hypertrophic chondrocytes through every examined stage (day 1 to day 10 after birth). On the other hand, in the condylar cartilage at days 1 and 5, MMP-13 was expressed throughout the proliferating and the hypertrophic chondrocytes, and at day 10, MMP-13 was mainly localized in the deepest edge of the hypertrophic layer. A zymographical study showed that the activity of MMP-13 in the condyle was observed at day 1, earlier than in the tibia, and increased until day 7. The time-dependent and cell-specific expression of MMP-13 and its enzymatic property suggest that in the mandibular condylar cartilage, MMP-13 plays a role in making the space for cell enlargement by degradation of the cartilage matrix and in onset of mineralization during the early stage of development.

Abstract
OBJECTIVE To investigate whether heterozygosity for a loss-of-function mutation in the gene encoding the alpha1 chain of type XI collagen (Col11a1) in mice (chondrodysplasia, cho) causes osteoarthritis (OA), and to understand the biochemical and biomechanical effects of this mutation on articular cartilage in knee and temporomandibular (TM) joints. METHODS Articular cartilage from the knee and TM joints of mice heterozygous for cho (cho/+) and their wild-type littermates (+/+) was examined. The morphologic properties of cartilage were evaluated, and collagen fibrils were examined by transmission electron microscopy. Immunohistochemical staining was performed to examine the protein expression levels of matrix metalloproteinase 3 (MMP-3) and MMP-13 in knee joints. In 6-month-old animals, fixed-charge density was determined using a semiquantitative histochemical method, and tensile stiffness was determined using an osmotic loading technique. RESULTS The diameter of collagen fibrils in articular cartilage of knee joints from heterozygous cho/+ mice was increased relative to that in control cartilage, and histologic analysis showed OA-like degenerative changes in knee and TM joints, starting at age 3 months. The changes became more severe with aging. At 3 months, protein expression for MMP-3 was increased in knee joints from cho/+ mice. At 6 months, protein expression for MMP-13 was higher in knee joints from cho/+ mice than in joints from their wild-type littermates, and negative fixed-charge density was significantly decreased. Moreover, tensile stiffness in articular cartilage of knee joints from cho/+ mice was moderately reduced and was inversely correlated with the increase in articular cartilage degeneration. CONCLUSION Heterozygosity for a loss-of-function mutation in Col11a1 results in the development of OA in the knee and TM joints of cho/+ mice. Morphologic and biochemical evidence of OA appears to precede significant mechanical changes, suggesting that the cho mutation leads to OA through a mechanism that does not initially involve mechanical factors.

Abstract
Expression of a constitutively active PTH/PTHrP receptor in cells of osteoblast lineage in vivo (CL2+) causes increases in trabecular bone volume and trabecular bone formation and, conversely, a decrease in the periosteal mineral apposition rate. Collagenase-3 (matrix metalloprotease-13) is a downstream target of PTH action. To investigate the relevance of collagenase cleavage of type I collagen for the CL2+ bone phenotype, we bred CL2+ animals with mice carrying a mutated col1 alpha 1 gene that encodes a protein resistant to digestion by collagenase-3 and other collagenases (rr). Adult tibias and parietal bones from 4-wk-old double-mutant animals (CL2+/rr) and from control littermates were analyzed. Trabecular bone volume was higher in CL2+/rr than in CL2+ mice. This increase occurred despite a modest reduction in bone formation rate, which was, however, still significantly higher that in wild-type littermates, and therefore must reflect decreased bone resorption in rr mice. Osteoclast number was increased in CL2+/rr animals compared with either wild-type or CL2+ mice, suggesting that collagenase-dependent collagen cleavage affected osteoclast function rather than osteoclast number and/or differentiation. Interestingly, the periosteal mineral apposition rate was similar in CL2+/rr and CL2+ animals and was significantly lower than that in wild-type animals. Our study provides evidence that collagenase activity is important for both basal and PTH/PTHrP receptor-dependent osteoclast activation. Furthermore, it indicates that a mild impairment of osteoclast activity is still compatible with increased osteoblast function. Lastly, it supports the hypothesis that collagenases can be a downstream effector of PTH/PTHrP receptor action in trabecular bone, but not in periosteum.

Abstract
Matrix metalloproteinases (MMPs) have been implicated in physiological cartilage matrix remodelling as well as in pathological and invasive extracellular matrix remodelling of tissue. Age-related changes in the gene expression patterns of MMPs in mandibular condylar cartilages (MCCs) were analysed. We examined the gene expression patterns of Mmp-8 and -13 and their substrates, Col1a1, Col2a1 and Col10a1, in MCC of growing and ageing rats. Temporomandibular joints of male Wistar rats aged 4, 8, 16 and 32 weeks were subjected to in situ hybridization analysis. Histologically, MMCs showed characteristics of growth plate cartilage at ages 4 and 8 weeks, and more closely resembled articular cartilage thereafter. Mmp-8 was expressed in the cells in all cartilaginous cell layers at ages 4 and 8 weeks, and then was localized only in the mature cells at ages 16 and 32 weeks. Whereas Mmp-13 expression was limited to the lowermost hypertrophic chondrocytes in the growth stage, mature chondrocytes instead of hypertrophic chondrocytes expressed Mmp-13 in adult non-hypertrophic MCC. Because Mmp-8 and -13 expression overlapped with Col2a1 and Col10a1, chondrocytes could play a pivotal role in degradation as well as production of the cartilaginous matrix in MCC.

Abstract
Periodontal ligament tissue is remodeled on both the tension and compression sides of moving teeth during orthodontic tooth movement. The present study was designed to clarify the hypothesis that the expression of MMP-8 and MMP-13 mRNA is promoted during the remodeling of periodontal ligament tissue in orthodontic tooth movement. We used the in situ hybridization method and semi-quantitative reverse-transcription/polymerase chain-reaction analysis to elucidate the gene expression of MMP-8 and MMP-13 mRNA. Expression of MMP-8 and MMP-13 mRNA transiently increased on both the compression and tension sides during active tooth movement in vivo. The gene expression of MMP-8 and MMP-13 was induced by tension, while compression indirectly promoted the gene expression of MMP-8 and MMP-13 through soluble factors in vitro. Thus, we concluded that the expression of MMP-8 and MMP-13 is differentially regulated by tension and compression, and plays an important role in the remodeling of the periodontal ligament.

Abstract
Tumor necrosis factor alpha (TNF-alpha), a major proinflammatory cytokine, induces arthritic joint inflammation and resorption of cartilage by matrix metalloproteinase-13 (MMP-13). RNA for MMP-13 is increased in human arthritic femoral cartilage. Mechanisms of this induction were investigated by pretreating primary human osteoarthritic (OA) femoral head chondrocytes or chondrosarcoma cells with the potential inhibitors of TNF-alpha signal transduction and downstream target transcription factors followed by stimulation with TNF-alpha and analysis of MMP-13 RNA/protein. TNF-alpha rapidly activated phosphorylation of extracellular signal-regulated kinases (ERKs), p38, and c-jun N-terminal kinase (JNK) mitogen-activated protein (MAP) kinases in human chondrocytes. Inhibitors of ERK (U0126, PD98059, and ERK1/2 antisense phosphorothioate oligonucleotide), JNK (SB203580, SP600125, and curcumin), and p38 (SB203580 and SB202190) pathways down-regulated the TNF-stimulated expression of MMP-13. Inhibitors of the transcription factors AP-1 (nordihydroguaiaretic acid, NDGA) and NF-kappaB (curcumin, proteasome inhibitors, and Bay-11-7085) suppressed TNF-alpha-induced MMP-13 expression in primary chondrocytes and SW1353 cells. These results suggest that induction of the MMP-13 gene by TNF-alpha is mediated by ERK, p38, and JNK MAP kinases as well as AP-1 and NF-kappaB transcription factors. Blockade of TNF-alpha signaling and its target transcription factors by the approaches tested here may be beneficial for reducing cartilage breakdown by MMP-13 in arthritis.

Abstract
The aim of the present observational study was to identify and characterize matrix metalloproteinase (MMP) -2, -8, -9, and -13 in gingival crevicular fluid (GCF) of patients with short root anomaly (SRA). GCF samples collected from affected maxillary central incisors and premolars of five SRA patients and five systemically and periodontally healthy controls were analysed using the zymographic technique for gelatinase A and B (MMP-2 and -9) and by Western blot for collagenase -2 and -3 (MMP-8 and -13). SRA GCF revealed MMP-9 (30 per cent of the total gelatinolytic activity), of which 18 per cent was in 90 kDa proform and 12 per cent in 71-82 kDa active form. Moreover, high-molecular weight complexes (37 per cent) and low-molecular size fragmented (33 per cent) gelatinolytic enzymes were detectable. No MMP-8 or -13 immunoreactivities existed. These results may suggest that activation and complex formation of MMP-9 is characteristic of SRA GCF. From the findings it may be assumed that the GCF of SRA teeth has low collagenolytic resorptive or pathological activity.

Abstract
Matrix metalloproteinases (MMPs) are involved in many physiological and pathophysiological processes, including tumor cell invasion and metastasis. For one member of this family, MMP-13 (collagenase-3), a new, highly specific ELISA with a sensitivity of 0.5 ng MMP-13/ml was established. The protein levels of MMP-13 in ascitic fluids of 30 patients with advanced ovarian cancer FIGO stage III (n = 19) and IV (n = 11) were measured with this ELISA. Using a cut-off value of 0.5 ng MMP-13/mg total protein, two patient subpopulations with short (median 16 months) and long (median 36 months) overall survival were identified. Together with other prognostic markers, determination of MMP-13 in ascitic fluid may help to identify patients at risk for early death and help to individualize adjuvant therapy.

Abstract
We investigated the influence of estrogenic and antiestrogenic treatment on proteolytic activity--especially on MMP-2 and MMP-13--in the RUCA-I transplantable endometrial tumor model. Morphological studies demonstrate that RUCA-I cells are forming highly differentiated gland-like structures by remodelling and invading the underlying ECM. Estrogens upregulate the mRNA levels of MMP-2 and MMP-13 in the rat uterus. Treatment with the pure antiestrogen ICI 182,780 results in the downregulation of MMP-2 and MMP-13 mRNA. The same regulation for MMP-13 mRNA is found in vitro in RUCA-I cells. In contrast, in the transplantation tumor, the mRNA level of MMP-13 is repressed by estrogens and induced by ICI 182,780. MMP-2 mRNA is not regulated by hormones in the transplantation tumor and in RUCA-I cells. The divergent regulation suggests a varying influence of cell-cell-, cell-extracellular matrix interactions and soluble factors.

Abstract
Phosphinic acid-based inhibitors of MMP-13 have been investigated with the aim of identifying potent inhibitors with high selectivity versus MMP-1. Independent variation of the substituents on a P(1)' phenethyl group and a P(2) benzyl group improved potencies in both cases around 3-fold over the unsubstituted parent. Combining improved P(1)' and P(2) groups into a single molecule gave an inhibitor with a 4.5 nM IC(50) against MMP-13 and which is 270-fold selective over MMP-1.

Abstract
OBJECTIVES The purpose of this study was to determine the pathogenic factors and molecular mechanisms involved in fibrosis of the atria. BACKGROUND Fibrosis is an important component of the pathophysiology of atrial fibrillation, especially when the arrhythmia is associated with heart failure (HF) or atrial dilation. METHODS We used a rat model of myocardial infarction (MI) complicated by various degrees of left ventricular dysfunction and atrial dilation to study fibrosis and matrix metalloproteinase (MMP) activity in the left atrial (LA) myocardium by means of histologic, Western blot, zymographic, and immunohistologic techniques. RESULTS Three months after surgical ligature of the left coronary artery, 27 rats had a large MI, 12 were in mild HF, and 15 in severe HF. Both groups had LA enlargement at the echocardiography. Masson's trichrome and picrosirius staining of tissue sections revealed marked fibrosis at the periphery of trabeculae and also surrounding myolytic myocytes, in both mild and severe HF. In mild HF, the activity and expression of the matrilysin MMP-7 were increased (122%), whereas in severe HF, both MMP-7 (211%) and the gelatinase MMP-2 (187%) were up-regulated. There were no changes in the expression or activity of MMP inhibitors, TIMP-1, -2, and -4. Immunostaining of cryosections showed that MMP-2 was present in the interstitial spaces, whereas MMP-7 accumulated in myolytic myocytes. CONCLUSIONS Hemodynamic overload of the atria is an important pathogenic factor of fibrosis; MMP-7 appears to be involved in the early stage of this tissue remodeling process.

Abstract
Matrix metalloproteinase-13 (collagenase-3), a member of the family of matrix metalloproteinases (MMPs), plays a major pathological role in the cartilage destruction of arthritis. A dramatic up-regulation of MMP-13 by inflammatory cytokines such as interleukin (IL)-1beta or by fibronectin fragments has been observed in chondrocytes. In this study, we investigated the inhibitory effects of insulin-like growth factor-1 (IGF-1) and osteogenic protein-1 (OP-1) on the expression of MMP-13, which was induced by fibronectin fragment or IL-1beta in human immortalized or human primary chondrocytes. IGF-1 and OP-1 each significantly reduced the basal level as well as fibronectin fragment- or IL-1beta-stimulated transcription of the MMP-13 gene in a dose-dependent fashion with the corresponding decreases in the protein level of MMP-13. The most prominent suppressive effect was observed by the combination of IGF-1 and OP-1, which decreased the basal promoter activity by 60% and almost completely abrogated the fibronectin fragment-stimulated MMP-13 promoter activity. OP-1 was found to enhance mRNA levels of IGF-1 and the IGF-1 receptor, the latter of which appeared to be responsible for the combined effect of IGF-1 and OP-1. The suppressive effect of IGF-1 and OP-1 on MMP-13 expression was due in part to down-regulation of the expression of pro-inflammatory cytokines and the activity of their intermediate molecules, including NF-kappaB and AP-1 factors. We propose that IGF-1 and OP-1 could be key physiological regulators of MMP-13 gene expression and that the combination of IGF-1 and OP-1 may be useful in controlling the excess catabolic activity in arthritis.

Abstract
We hypothesized that formation of advanced glycation end products (AGEs) associated with diabetes reduces matrix degradation by metalloproteinases (MMPs) and contributes to the impairment of ischemia-induced angiogenesis. Mice were treated or not with streptozotocin (40 mg/kg) and streptozotocin plus aminoguanidine (AGEs formation blocker, 50 mg/kg). After 8 weeks of treatment, hindlimb ischemia was induced by right femoral artery ligature. Plasma AGE levels were strongly elevated in diabetic mice when compared with control mice (579 +/- 21 versus 47 +/- 4 pmol/ml, respectively; P < 0.01). Treatment with aminoguanidine reduced AGE plasma levels when compared with untreated diabetic mice (P < 0.001). After 28 days of ischemia, ischemic/nonischemic leg angiographic score, capillary density, and laser Doppler skin-perfusion ratios were 1.4-, 1.5-, and 1.4-fold decreased in diabetic mice in reference to controls (P < 0.01). Treatment with aminoguanidine completely normalized ischemia-induced angiogenesis in diabetic mice. We next analyzed the role of proteolysis in AGE formation-induced hampered neovascularization process. After 3 days of ischemia, MMP-2 activity and MMP-3 and MMP-13 protein levels were increased in untreated and aminoguanidine-treated diabetic mice when compared with controls (P < 0.05). Despite this activation of the MMP pathway, collagenolysis was decreased in untreated diabetic mice. Conversely, treatment of diabetic mice with aminoguanidine restored collagenolysis toward levels found in control mice. In conclusion, blockade of AGE formation by aminoguanidine normalizes impaired ischemia-induced angiogenesis in diabetic mice. This effect is probably mediated by restoration of matrix degradation processes that are disturbed as a result of AGE accumulation.

Abstract
Fibronectin fragments (FN-f), including the 110-kDa fragment that binds the alpha5beta1 integrin, stimulate collagenase-3 (MMP-13) production and cartilage destruction. In the present study, treatment of chondrocytes with the 110-kDa FN-f or an activating antibody to the alpha5beta1 integrin was found to increase tyrosine autophosphorylation (Tyr-402) of the proline-rich tyrosine kinase-2 (PYK2) without significant change in autophosphorylation (Tyr-397) of focal adhesion kinase (FAK). The tyrosine kinase inhibitor tyrphostin A9, shown previously to block a PYK2-dependent pathway, blocked the FN-f-stimulated increase in MMP-13, whereas tyrphostin A25 did not. FN-f-stimulated PYK2 phosphorylation and MMP-13 production was also blocked by reducing intracellular calcium levels. Adenovirally mediated overexpression of wild type but not mutant PYK2 resulted in increased MMP-13 production. The protein kinase C (PKC) activator phorbol 12-myristate 13-acetate stimulated PYK2 phosphorylation and MMP-13 production. MMP-13 expression stimulated by either phorbol 12-myristate 13-acetate or FN-f was blocked by PKC inhibitors including the PKCdelta inhibitor rottlerin. Furthermore, PKCdelta translocation from cytosol to membrane was noted within 5 min of stimulation with FN-f. Immortalized human chondrocytes, transiently transfected with MMP-13 promoter-luciferase reporter constructs, showed increased promoter activity after FN-f treatment that was inhibited by co-transfection with either of two dominant negative mutants of PYK2 (Y402F and K457A). No inhibition was seen after cotransfection with wild type PYK2, a dominant negative of FAK (FRNK) or empty vector plasmid. FN-f-stimulated MMP-13 promoter activity was also inhibited by chemical inhibitors of ERK, JNK, and p38 mitogen-activated protein (MAP) kinases or by co-transfection of dominant negative MAP kinase mutant constructs. These studies have identified a novel pathway for the MAP kinase regulation of MMP-13 production which involves FN-f stimulation of the alpha5beta1 integrin and activation of the nonreceptor tyrosine kinase PYK2 by PKC, most likely PKCdelta

Abstract
BACKGROUND Synovial tissue (ST) from end stage destructive rheumatoid arthritis (RA) and arthroscopic biopsies obtained during active inflammation might exhibit different characteristics. OBJECTIVE To define the cell infiltrate and the expression of proinflammatory cytokines, angiogenic factors, and matrix metalloproteinases (MMPs) in ST selected at arthroscopy compared with that from end stage RA. METHODS Synovial biopsy specimens were obtained from the actively inflamed knee joints of 13 patients with chronic RA by arthroscopy and compared with ST from 10 patients with end stage, destructive RA. Immunohistological analysis was performed to detect T cells, plasma cells, macrophages, fibroblast-like synoviocytes (FLS), and the expression of interleukin (IL)1beta, IL6, tumour necrosis factor alpha (TNFalpha), MMP-1, MMP-3, MMP-13, TIMP-1, and VEGF. RESULTS The expression of CD68+ macrophages was significantly higher in ST selected at arthroscopy than in samples obtained at surgery, both in the intimal lining layer and in the synovial sublining. The expression of CD3+ T cells also tended to be higher in arthroscopic samples. The expression of TNFalpha, IL6, MMP-1, MMP-3, MMP-13, TIMP-1, and VEGF was on average higher in ST obtained at arthroscopy. In contrast, the expression of IL1beta was on average higher in surgical samples. CONCLUSION Active arthritis activity is associated with increased cell infiltration, expression of proinflammatory cytokines, MMPs, and angiogenic growth factors in synovial biopsy samples selected at arthroscopy. Increased expression of IL1beta in the synovium of patients with destructive RA requiring joint replacement may well reflect the important role of IL1beta in cartilage and bone destruction.
