Abstract
Matrix metalloproteinase-9 (MMP-9) cleaves various proteins to regulate inflammatory and injury responses. However, MMP-9's activities during influenza A viral (IAV) infections are incompletely understood. Herein, plasma MMP-9 levels were increased in patients with pandemic H1N1 and seasonal IAV infections. MMP-9 lung levels were increased and localized to airway epithelial cells and leukocytes in H1N1-infected WT murine lungs. H1N1-infected Mmp-9-/- mice had lower mortality rates, reduced weight loss, lower lung viral titers, and reduced lung injury, along with lower E-cadherin shedding in bronchoalveolar lavage fluid (BALF) samples than WT mice. H1N1-infected Mmp-9-/- mice had an altered immune response to IAV with lower BALF PMN and macrophage counts, higher Th1-like CD4+ and CD8+ T cell subsets, lower T regulatory cell counts, reduced lung type I interferon levels, and higher lung interferon-γ levels. Mmp-9 bone marrow-chimera studies revealed that Mmp-9 deficiency in lung parenchymal cells protected mice from IAV-induced mortality. H1N1-infected Mmp-9-/- lung epithelial cells had lower viral titers than H1N1-infected WT cells in vitro. Thus, H1N1-infected Mmp-9-/- mice are protected from IAV-induced lung disease due to a more effective adaptive immune response to IAV and reduced epithelial barrier injury due partly to reduced E-cadherin shedding. Thus, we believe that MMP-9 is a novel therapeutic target for IAV infections.

Abstract
The extracellular matrix (ECM) is a highly dynamic noncellular structure that is crucial for maintaining tissue architecture and homeostasis. The dynamic nature of the ECM undergoes constant remodeling in response to stressors, tissue needs, and biochemical signals that are mediated primarily by matrix metalloproteinases (MMPs), which work to degrade and build up the ECM. Research on MMP-9 has demonstrated that this proteinase exists on the cell surface of many cell types in complex with G protein-coupled receptors (GPCRs), and receptor tyrosine kinases (RTKs) or Toll-like receptors (TLRs). Through a novel yet ubiquitous signaling platform, MMP-9 is found to play a crucial role not only in the direct remodeling of the ECM but also in the transactivation of associated receptors to mediate and recruit additional remodeling proteins. Here, we summarize the role of MMP-9 as it exists in a tripartite complex on the cell surface and discuss how its association with each of the TrkA receptor, Toll-like receptors, epidermal growth factor receptor, and the insulin receptor contributes to various aspects of ECM remodeling.

Abstract
Background VEGF proteolysis by plasmin or matrix metalloproteinases (MMPs) is believed to play an important role in regulating vascular patterning in vivo by releasing VEGF from the extracellular matrix (ECM). However, a quantitative understanding of the kinetics of VEGF cleavage and the efficiency of cell-mediated VEGF release is currently lacking. To address these uncertainties, we develop a molecular-detailed quantitative model of VEGF proteolysis, used here in the context of an endothelial sprout. Methodology and Findings To study a cell's ability to cleave VEGF, the model captures MMP secretion, VEGF-ECM binding, VEGF proteolysis from VEGF165 to VEGF114 (the expected MMP cleavage product of VEGF165) and VEGF receptor-mediated recapture. Using experimental data, we estimated the effective bimolecular rate constant of VEGF165 cleavage by plasmin to be 328 M−1s−1 at 25°C, which is relatively slow compared to typical MMP-ECM proteolysis reactions. While previous studies have implicated cellular proteolysis in growth factor processing, we show that single cells do not individually have the capacity to cleave VEGF to any appreciable extent (less than 0.1% conversion). In addition, we find that a tip cell's receptor system will not efficiently recapture the cleaved VEGF due to an inability of cleaved VEGF to associate with Neuropilin-1. Conclusions Overall, VEGF165 cleavage in vivo is likely to be mediated by the combined effect of numerous cells, instead of behaving in a single-cell-directed, autocrine manner. We show that heparan sulfate proteoglycans (HSPGs) potentiate VEGF cleavage by increasing the VEGF clearance time in tissues. In addition, we find that the VEGF-HSPG complex is more sensitive to proteases than is soluble VEGF, which may imply its potential relevance in receptor signaling. Finally, according to our calculations, experimentally measured soluble protease levels are approximately two orders of magnitude lower than that needed to reconcile levels of VEGF cleavage seen in pathological situations.

Abstract
Integrin alphavbeta3 and matrix metalloprotease-2 (MMP-2) are two established molecular targets of angiogenesis. Basic understanding of various forms of functional interaction of integrin alphavbeta3 and active MMP-2 may be used to develop therapeutic approaches. Based upon the idea that integrins are present on the surface of invasive cells and MMP-2 may be localized to this and other cell-surface receptors, we investigated the hypothesis that integrin binding will alter cleavage of MMP-2 substrates. To investigate this hypothesis, integrin-binding and MMP-2 cleavable motifs were combined in a single peptide, MMP-RGD, designed with fluorescent probes for monitoring peptide cleavage. MMP-RGD was bound to integrin alphavbeta3 with equal affinity compared to the integrin-binding motif and was cleaved with equal specificity by active MMP-2. MMP-RGD bound to human umbilical vein endothelial cells (HUVECs). MMP-2 from HUVECs cleaved MMP-RGD, but the cleavage was not altered due to integrin binding. Our results indicate that integrin alphavbeta3 and active MMP-2 may not be as functionally collaborative for substrate cleavage as expected based on the current knowledge of their cell surface colocalization.

Abstract
Cellular invasive behavior through three-dimensional collagen gels was analyzed using computational time-lapse imaging. A subpopulation of endocardial cells, derived from explanted quail cardiac cushions, undergoes an epithelial-to-mesenchymal transition and invades the substance of the collagen gels when placed in culture. In contrast, other endocardial cells remain epithelial and move over the gel surface. Here, we show that integrin alpha(v)beta3 and matrix metalloproteinase (MMP)2 are present and active in cushion mesenchymal tissue. More importantly, functional assays show that mesenchymal invasive behavior is dependent on MMP2 activity and integrin alpha(v)beta3 binding. Inhibitors of MMP enzymatic activity and molecules that prevent integrin alpha(v)beta3 binding to MMP2, via its hemopexin domain, result in significantly reduced cellular protrusive activity and invasive behavior. Computational analyses show diminished intensity and persistence time of motility in treated invasive mesenchymal cells, but no reduction in motility of the epithelial-like cells moving over the gel surface. Thus, quantitative time-lapse data show that mesenchymal cell invasive behavior, but not epithelial cell locomotion over the gel surface, is partially regulated by the MMP2-integrin interactions.

Abstract
Matrix metalloproteinase-9 (MMP-9) is implicated in tumor metastasis as well as a variety of inflammatory and pathological processes. Although many substrates for MMP-9, including components of the extracellular matrix, soluble mediators such as chemokines, and cell surface molecules have been identified, we undertook a more comprehensive proteomics-based approach to identify new substrates to further understand how MMP-9 might contribute to tumor metastasis. Previous proteomics approaches to identify protease substrates have depended upon differential labeling of each sample. Instead we used a label-free quantitative proteomics approach based on ultraperformance LC-ESI-high/low collision energy MS. Conditioned medium from a human metastatic prostate cancer cell line, PC-3ML, in which MMP-9 had been down-regulated by RNA interference was compared with that from the parental cells. From more than 200 proteins identified, 69 showed significant alteration in levels after depletion of the protease (>+/-2-fold), suggesting that they might be candidate substrates. Levels of six of these (amyloid-beta precursor protein, collagen VI, leukemia inhibitory factor, neuropilin-1, prostate cancer cell-derived growth factor (PCDGF), and protease nexin-1 (PN-1)) were tested in the conditioned media by immunoblotting. There was a strong correlation between results by ultraperformance LC-ESI-high/low collision energy MS and by immunoblotting giving credence to the label-free approach. Further information about MMP-9 cleavage was obtained by comparison of the peptide coverage of collagen VI in the presence and absence of MMP-9 showing increased sensitivity of the C- and N-terminal globular regions over the helical regions. Susceptibility of PN-1 and leukemia inhibitory factor to MMP-9 degradation was confirmed by in vitro incubation of the recombinant proteins with recombinant MMP-9. The MMP-9 cleavage sites in PN-1 were sequenced. This study provides a new label-free method for degradomics cell-based screening leading to the identification of a series of proteins whose levels are affected by MMP-9, some of which are clearly direct substrates for MMP-9 and become candidates for involvement in metastasis.

Abstract
MMP-9 (matrix metalloproteinase 9) plays a critical role in tumour progression. Although the biochemical properties of the secreted form of proMMP-9 are well characterized, little is known about the function and activity of cell surface-associated proMMP-9. We purified a novel 82 kDa species of proMMP-9 from the plasma membrane of THP-1 leukaemic cells, which has substantial differences from the secreted 94 kDa proMMP-9. The 82 kDa form was not detected in the medium even upon stimulation with a phorbol ester. It is truncated by nine amino acid residues at its N-terminus, lacks O-linked oligosaccharides present in the 94 kDa proMMP-9, but retains N-linked carbohydrates. Incubation of 94 kDa proMMP-9 with MMP-3 generated the well-known 82 kDa active form, but the 82 kDa proMMP-9 was converted into an active species of 35 kDa, which was also produced by autocatalytic processing in the absence of activating enzymes. The activated 35 kDa MMP-9 efficiently degraded gelatins, native collagen type IV and fibronectin. The enzyme was less sensitive to TIMP-1 (tissue inhibitor of metalloproteinase 1) inhibition with IC50 values of 82 nM compared with 1 nM for the 82 kDa active MMP-9. The synthetic MMP inhibitor GM6001 blocked the activity of both enzymes, with similar IC50 values below 1 nM. The 82 kDa proMMP-9 is also produced in HL-60 and NB4 leukaemic cell lines as well as ex vivo leukaemic blast cells. It is, however, absent from neutrophils and mononuclear cells isolated from peripheral blood of healthy individuals. Thus, the 82 kDa proMMP-9 expressed on the surface of malignant cells may escape inhibition by natural TIMP-1, thereby facilitating cellular invasion in vivo.

Abstract
The effect of the expression of cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) synthesis on cell migration, the secretion of matrix metalloproteinases (MMPs) and the adhesion of human hepatoma cell lines has been investigated. A close correlation was observed between the expression of COX-2 under basal conditions and the secretion of MMP-2 and MMP-9. Cell migration in HuH-7 cells, which express high constitutive levels of COX-2 was significantly inhibited by selective inhibitors of COX-2 and enhanced by exogenous addition of PGE2. Hepatocellular carcinoma (HCC) cells expressed beta1 and alphaV beta3 integrins, exhibiting an increase in cell adhesion onto fibronectin and vitronectin. Moreover, addition of PGE2 increased the beta1 integrin levels and adhesion on vitronectin in HuH-7 cells. Inhibitors of MEK/ERK, p38 MAPK, protein kinases A and C impaired the migration of HuH-7 cells induced by PGE2, indicating the involvement of multiple pathways in the process. Taken together, these results support the existence of a relationship between COX-2-derived PGE2 synthesis, and migration and adhesion through an integrin-dependent pathway in HCC cells.

Abstract
Association of matrix metalloprotease 9 (MMP9) to the cell membrane is considered important in tumor growth and angiogenesis. To dissect this regulatory mechanism, we generated raft and non-raft MMP9 chimeras to force membrane expression in the MCF-7 human breast carcinoma cell line. MMP9 targeting to non-raft cell surface domains rendered a constitutive active membrane MMP9 form, suggesting a contribution by the lipid environment in MMP activation. We generated human breast cancer xenograft models using MCF-7 cells overexpressing secreted and membrane-anchored MMP9. The non-raft MMP9 chimera was constitutively active at the cell membrane in xenografts, but this activation did not correlate with an increase in MMP9-induced angiogenesis. Capillary number and vessel perimeter were specifically increased only in tumors overexpressing wild-type MMP9 (the secreted form); this increase was inhibited when tumors were induced in doxycycline-treated mice. Xenografts from tumor cells overexpressing wild-type MMP9 showed increased vascular endothelial growth factor (VEGF)/VEGFR2 receptor association, which was also dependent on MMP9 activity. These observations indicate that membrane location can influence MMP9 activity in vitro and in vivo, and confirm the relevance of stromal-associated, but not tumor-bound MMP9 in mediating tumor-induced angiogenesis.

Abstract
OBJECTIVE Constrictive remodeling accounts for lumen loss in postangioplasty restenosis. Matrix metalloproteinase-9 (MMP-9) has been shown to prevent constrictive remodeling in vivo. To investigate potential mechanisms for this observation, we investigated the role of MMP-9 in smooth muscle cell (SMC)-mediated collagen gel contraction, an in vitro model of constrictive remodeling. METHODS Fischer rat SMCs were stably transfected with a construct-expressing rat-MMP-9 under the control of a tetracycline (Tet)-off promoter. SMCs were seeded in type I collagen gels (2.4 mg/ml) in the presence or not of tetracycline (1 microg/ml), and gel contraction was defined as the percentage of retraction of the collagen gel. The depletion of MMP-9 was obtained by using siRNA targeting MMP-9 mRNA or a blocking antibody. RESULTS Gel contraction was significantly reduced at all times when MMP-9 was overexpressed (Tet-) as compared with the control condition (Tet+). However, MMP-9 depletion of control (Tet+) SMCs (using siRNA or antibody) also inhibited gel contraction. To resolve the apparent discrepancy and determine if MMP-9 exerts a dose-dependent biphasic effect on gel contraction, conditioned medium and purified rat-MMP-9 were prepared. Gel contraction was significantly increased by addition of 0.8 ng/ml of MMP-9, while high concentrations of MMP-9 (> or =100 ng/ml) inhibited contraction. The addition of BB94 and TIMP-1 did not alter the inhibitory or stimulatory effect of MMP-9. CONCLUSIONS Our data suggest that MMP-9, independent of its proteolytic function, has a biphasic effect on SMC-mediated collagen gel contraction. Understanding the different roles of MMP-9 should allow the development of better therapeutic strategies for restenotic vascular disease.

Abstract
Chronic obstructive pulmonary disease is marked by alveolar enlargement and excess production of airway mucus. Acrolein, a component of cigarette smoke, increases mucin 5AC (MUC5AC), a prevalent airway mucin in NCI-H292 cells by transcriptional activation, but the signal transduction pathways involved in acrolein-induced MUC5AC expression are unknown. Acrolein depleted cellular glutathione at doses of 10 muM or greater, higher than those sufficient (0.03 muM) to increase MUC5AC mRNA, suggesting that MUC5AC expression was independent of oxidative stress. In contrast, acrolein increased MUC5AC mRNA levels by phosphorylating epidermal growth factor receptor (EGFR) and mitogen-activated protein kinase 3/2, or MAPK 3/2(ERK1/2). Pretreating the cells with an EGFR-neutralizing antibody, or a metalloproteinase inhibitor, decreased the acrolein-induced MUC5AC mRNA increase. Small, interfering RNA directed against ADAM17 or MMP9 inhibited the acrolein-induced MUC5AC mRNA increase. Acrolein increased the release and subsequent activation of pro-MMP9. Acrolein increased MMP9 and decreased tissue inhibitor of metalloproteinase 3 (TIMP3), an endogenous inhibitor of ADAM17, transcripts. Together, these data suggest that acrolein induces MUC5AC expression via an initial ligand-dependent activation of EGFR mediated by ADAM17 and MMP9. In addition, a prolonged effect of acrolein may be mediated by altering MMP9 and TIMP3 transcription.

Abstract
We used a two-compartment coculture model comprising human endothelial cells (EC) and non-small cell lung carcinoma (CA) cells to study capillary formation. Elevated NO concentrations, contributed in part by CA cells, lead to inhibited capillary formation (Phillips PG, Birnby LM, Narendran A, and Milonovich WL. Am J Physiol Lung Cell Mol Physiol 281: L278-L290, 2001). Here we demonstrate using gelatin substrate zymography that high NO concentrations, whether produced endogenously or by NO donor spermine-NONOate or peroxynitrite-generating compound SIN-1, significantly inhibit MMP-9 expression and activation. Furthermore, high NO concentrations decrease Cav-1 abundance and alter its cellular distribution in EC. Cav-1 is essential for capillary formation in this model because Cav-1 antisense treatments targeted to EC significantly inhibit capillary formation. Laser confocal microscopy demonstrated extensive colocalization of MMP-9 with Cav-1 in sprouting EC, primarily at the basolateral surfaces of EC in focal structures associated with directed migration. This codistribution was NO concentration dependent, and elevated NO concentrations lead to marked dissociation of these two proteins. We propose that compartmentalization of MMP-9 within caveolar structures does occur, and that this could facilitate directed proteolysis essential for early migratory and invasive processes. Our data suggest elevated NO concentrations could impact on capillary formation via a combination of direct effects on MMP activation and by altering the distribution or abundance of Cav-1. Consequences of Cav-1 alterations may include impaired activation of proteolytic enzymes that utilize caveolar structure for stabilization and/or compartmentalization of MMP-9 as well as other putative members of an ECM proteolytic cascade.

Abstract
We evaluated whether tumor necrosis factor (TNF)-alpha induces an increase in permeability of an alveolar epithelial monolayer via gelatinase secretion and basement membrane degradation. Gelatinase secretion and epithelial permeability to radiolabeled albumin under unstimulated and TNF-alpha-stimulated conditions of an A549 human epithelial cell line were evaluated in vitro. TNF-alpha induced both upregulation of a 92-kDa gelatinolytic activity (pro form in cell supernatant and activated form in extracellular matrix) and an increase in the epithelial permeability coefficient compared with the unstimulated condition (control: 1.34 +/- 0.04 x 10(-6) cm/s; 1 microg/ml TNF-alpha: 1.47 +/- 0.05 x 10(-6) cm/s, P < 0.05). The permeability increase in the TNF-alpha-stimulated condition involved both paracellular permeability, with gap formation visualized by actin cytoskeleton staining, and basement membrane permeability, with an increase in the basement membrane permeability coefficient (determined after cell removal; control: 2.58 +/- 0.07 x 10(-6) cm/s; 1 microg/ml TNF-alpha: 2.82 +/- 0.02.10(-6) x cm/s, P < 0.05). Because addition of gelatinase inhibitors [tissue inhibitor of metalloproteinase (TIMP)-1 or BB-3103] to cell supernatants failed to inhibit the permeability increase, the gelatinase-inhibitor balance in the cellular microenvironment was further evaluated by cell culture on a radiolabeled collagen matrix. In the unstimulated condition, spontaneous collagenolytic activity inhibited by addition to the matrix of 1 microg/ml TIMP-1 or 10(-6) M BB-3103 was found. TNF-alpha failed to increase this collagenolytic activity because it was associated with dose-dependent upregulation of TIMP-1 secretion by alveolar epithelial cells. In conclusion, induction by TNF-alpha of upregulation of both the 92-kDa gelatinase and its inhibitor TIMP-1 results in maintenance of the gelatinase-inhibitor balance, indicating that basement membrane degradation does not mediate the TNF-alpha-induced increase in alveolar epithelial monolayer permeability.

Abstract
Nitric oxide synthase expression has been documented in lung tumors, but a potential role for nitric oxide (NO) in induction of capillary formation remains to be elucidated. The purpose of this report was to characterize the direct effects of NO at the level of the tumor-endothelium interface with respect to angiogenesis. A Transwell two-compartment culture system, human endothelial cells (EC), and two human non-small cell lung cancer (CA) lines that constitutively produce NO were used to simulate the EC-tumor cell interface. Both histological types of lung CA, squamous and adenocarcinoma, induced baseline capillary formation by EC within 3 days. This process was inhibited by NO in the microenvironment because decreasing NO production with 100 microM aminoguanidine (AG) significantly increased capillary formation, whereas coincubation with 100 microM AG plus 400 microM L-arginine returned angiogenesis to baseline values. We demonstrate further that NO may exert its inhibitory effects by influencing matrix metalloproteinase expression/activity and tyrosine phosphorylation of proteins in the sprouting tips of nascent capillaries.

Abstract
To investigate the role of gelatinases in nasal polyposis, a common and disabling airway disease characterized by chronic inflammation and tissue remodelling, matrix metalloproteinase-2 (MMP-2) and MMP-9 expression was investigated in the nasal polyps (NP) of 24 patients undergoing ethmoidectomy and compared with 15 control nasal mucosal (CM) samples obtained from snorers during turbinectomy. Tissue samples were either frozen for enzymatic analysis or paraffin wax-embedded for immunohistochemistry. Zymography and quantitative image analysis showed that MMP-9 active forms were significantly increased (p<0.05) in NPs compared to CM (44 +/- 40 versus 13 +/- 19x10(3) AU/10 microg protein), while MMP-2 expression was similar in both tissues. Concomitant studies of gelatinase immunoexpression showed that MMP-9 expression was enhanced (4- to 16-fold) in surface epithelium, glands (p<0.05), and submucosal inflammatory cells (p<0.05). In addition, MMP-9 positivity was markedly increased in endothelial cells (p<0.01). In situ zymography demonstrated marked gelatinolytic activity, consistent with the immunolocalization of MMP-2 and MMP-9. These results suggest up-regulation of active MMP-9 in the glands and vessels characteristic of NPs. It is concluded that MMP-9 may play a role in the upper airway remodelling observed during nasal polyposis.

Abstract
Both serine and metalloproteinases have been implicated in the complex integrated events underlying cell migration but no definitive single mechanism has emerged. Work over the past two years linking both membrane and soluble proteinases with integrins and other adhesion proteins and with intracellular signalling systems could herald the beginnings of a potential expansion of our understanding of the role and regulation of proteolysis in cell migration.

Abstract
Cell spreading and migration associated with the expression of the 92-kD gelatinase (matrix metalloproteinase 9 or MMP-9) are important mechanisms involved in the repair of the respiratory epithelium. We investigated the location of MMP-9 and its potential role in migrating human bronchial epithelial cells (HBEC). In vivo and in vitro, MMP-9 accumulated in migrating HBEC located at the leading edge of a wound and MMP-9 expression paralleled cell migration speed. MMP-9 accumulated through an actin-dependent pathway in the advancing lamellipodia of migrating cells and was subsequently found active in the extracellular matrix (ECM). Lamellipodia became anchored through primordial contacts established with type IV collagen. MMP-9 became amassed behind collagen IV where there were fewer cell-ECM contacts. Both collagen IV and MMP-9 were involved in cell migration because when cell-collagen IV interaction was blocked, cells spread slightly but did not migrate; and when MMP-9 activation was prevented, cells remained fixed on primordial contacts and did not advance at all. These observations suggest that MMP-9 controls the migration of repairing HBEC by remodeling the provisional ECM implicated in primordial contacts.

Abstract
Activated keratinocytes synthesize increased amounts of matrix metalloproteinases during inflammation. Incubation of mucosal keratinocytes with TNFalpha (24 h) increased their expression of MMP-9 mRNA, which was followed by the corresponding increase in the expression of MMP-9 protein. This stimulation was dose dependent and continued for several days after the initial exposure to TNFalpha. In contrast, the expression of MMP-2 was not influenced by TNFalpha. IFNgamma caused a significant dose-dependent inhibition in the TNFalpha-stimulated expression of MMP-9. TNFalpha did not markedly influence keratinocyte growth, while INFgamma potently inhibited cell growth. Cytokine-stimulated keratinocytes secreted most MMP-2 and MMP-9 extracellularly into the culture medium, but MMP-9 was also found in the membrane extract of keratinocytes. Furthermore, wild-type and recombinant MMP-9 were bound to noncollageneous and nonintegrin components of the mucosal keratinocyte cell surface. MMP-9 was not, however, found in the extracellular matrix deposited by the keratinocytes in culture. Type I and IV collagens and gelatin but no other purified extracellular matrix nor basement membrane proteins (types I and IV collagen, laminin-1 and -5, fibronectin) were able to bind MMP-9 from the conditioned medium. Binding of MMP-9 from keratinocyte conditioned medium was demonstrated along the collagen fibers using immunoelectron microscopy. These phenomena may participate in extended matrix degradation in chronic inflammation.

Abstract
Recently, we have shown that the tumor necrosis factor-alpha (TNF-alpha)-induced morphological change of EA.hy 926 human endothelial cells is associated with a decrease in the net synthesis of two proteoglycans (PGs), biglycan and syndecan-1, both of which have been suggested to play a role in cell adhesion. Here we have examined whether this phenotypic modulation of EA.hy 926 cells also involves altered expression of matrix metalloproteinases (MMPs) or their tissue inhibitors (TIMPs). We demonstrate that, when forming cobblestone-like monolayer cultures, these cells express and synthesize collagenase-1 (MMP-1), stromelysin-1 (MMP-3) and 72 kDa (MMP-2) and 92 kDa (MMP-9) gelatinases, all of which have previously been found in either normal or pathological human vascular wall. EA.hy 926 cells also express membrane-typel MMP (MT1-MMP), but not matrilysin (MMP-7) and collagenase-3 (MMP-13). As regards TIMPs, we show that these cells express TIMP-1 and TIMP-2, but not TIMP-3 or TIMP-4. Exposure of the cells to TNF-alpha changed the cell morphology from a polygonal shape into a spindle shape and also increased the mRNA levels of MMP-1, MMP-3 and MMP-9, but slightly decreased the MMP-2 mRNA level. No change at the mRNA level of MT1-MMP was observed. Similarly to unstimulated cultures, no mRNA for MMP-7 or MMP-13 was detected in the TNF-alpha treated cultures. TNF-alpha had no effect on the TIMP-1 and TIMP-2 mRNA levels and did not induce TIMP-3 or TIMP-4 expression. Gelatin zymography and Western blot analysis revealed that the increase observed at the mRNA level of MMP-3 and MMP-9 was similar to that of their net protein level; furthermore, the active form of MMP-1 was induced. Our results indicate that the TNF-alpha-induced morphological change of EA.hy 926 cells is associated not only with specific changes in the expression of PGs by the cells, but also with specific changes in the expression of MMPs.
