Matrix Metalloproteinase-2 (MMP-2) is secreted as a zymogen, the activation of which has been associated with metastatic progression in human breast cancer (HBC). Concanavalin A (Con A) has been found to induce activation of MMP-2 in invasive HBC cell lines. Con A effects on the expression of mRNA for membrane-type matrix metalloproteinase (MT-MMP), a newly described cell surface-associated MMP, showed a close temporal correlation with induction of MMP-2 activation. It is surprising that MT-MMP mRNA is constitutively present in the uninduced MDA-MB-231 cell, despite a lack of MMP-2 activation. We have used actinomycin D to demonstrate a partial requirement for de novo gene expression in the induction of MMP-2 activation by Con A in MDA-MB-231 HBC cells. Furthermore, this transcriptional response to Con A appeared to require the continued presence of Con A for its manifestation. The nontranscriptional component of the Con A induction manifests rapidly, is quite substantial, and persists strongly ...

AU - Kashihara, Naoki. AU - Tian, Yufeng. AU - Wallner, Elisabeth I.. PY - 1999/12. Y1 - 1999/12. N2 - Extracellular matrix (ECM) proteins, their integrin receptors, and matrix metalloproteinases (MMPs), the ECM- degrading enzymes, are believed to be involved in various biological processes, including embryogenesis. In the present study, we investigated the role of membrane type MMP, MT-1-MMP, an activator pro-MMP-2, in metanephric development. Also, its relationship with MMP-2 and its inhibitor, TIMP-2, was studied. Since mRNAs of MT-1-MMP and MMP-2 are respectively expressed in the ureteric bud epithelia and mesenchyme, they are ideally suited for juxtacrine/paracrine interactions during renal development. Northern blot analyses revealed a single ~4.5-kb mRNA transcript of MT-1-MMP, and its ...

The processing mechanism and gelatinolytic activity of the membrane-type matrix metalloproteinase 1 (MT-MMP-1) were examined by expressing in COS-1 cells a deletion mutant of MT-MMP-1 lacking the trans-membrane domain (delta MT1) and its site-directed mutant with a furin-resistant sequence in the propeptide domain (mutant delta MT1). delta MT1, but not mutant delta MT1, was processed to an active form and exhibited gelatinolytic activity as seen using gelatin zymography. delta MT1 isolated in a complex form with tissue inhibitor of metalloproteinases 2 (TIMP-2) from the stable transfectants demonstrated the NH2-terminal sequence of Ala113-IIe-Gln-Leu, indicating cleavage at one amino acid down-stream from the furin recognition sequence. The delta MT1/TIMP-2 complex formed a ternary complex with proMMP-2 through the COOH termini of TIMP-2 and proMMP-2. A human breast carcinoma cell line (MDA-MB-231 cells) also secreted MT-MMP-1 into culture media, which was purified in a complex form with TIMP-2 and

Prions are the cause of neurodegenerative disease in humans and other mammals. The structural conversion of the prion protein (PrP) from a normal cellular protein (PrPC) to a protease-resistant isoform (PrPSc) is thought to relate to Cu2+ binding to histidine residues. In this study, we focused on the membrane-type matrix metalloproteinases (MT-MMPs) such as MT1-MMP and MT3-MMP, which are expressed in the brain as PrPC-degrading proteases. We synthesized 21 prion fragment peptides. Each purified peptide was individually incubated with recombinant MT1-MMP or MT3-MMP in the presence or absence of Cu2+ and the cleavage sites determined by LC-ESI-MS analysis. Recombinant MMP-7 and human serum (HS) were also tested as control. hPrP61-90, from the octapeptide-repeat region, was cleaved by HS but not by the MMPs tested here. On the other hand, hPrP92-168 from the central region was cleaved by MT1-MMP and MT3-MMP at various sites. These cleavages were inhibited by treatment with Cu2+. The C-terminal peptides

Among the five membrane-type matrix metalloproteinases (MT-MMPs), MT1-, MT2-, MT3-, and MT5-MMPs have about a 20-amino acid cytoplasmic tail following the transmembrane domain. In contrast, a putative transmembrane domain of MT4-MMP locates at the very C-terminal end, and the expected cytoplasmic tail is very short or nonexistent. Such sequences often act as a glycosylphosphatidylinositol (GPI) anchoring signal rather than as a transmembrane domain. We thus examined the possibility that MT4-MMP is a GPI-anchored proteinase. Our results showed that [(3)H]ethanolamine, which can be incorporated into the GPI unit, specifically labeled the MT4-MMP C-terminal end in a sequence-dependent manner. In addition, phosphatidylinositol-specific phospholipase C treatment released the MT4-MMP from the surface of transfected cells. These results indicate that MT4-MMP is the first GPI-anchored proteinase in the MMP family. During cultivation of the transfected cells, MT4-MMP appeared to be shed from the cell surface by

Matrix metalloproteinases (MMPs) have been implicated as important factors in gliomas since they may both facilitate invasion into the surrounding brain and participate in neovascularization.

N2 - Gelatinase A is secreted as a proenzyme (progelatinase A) which is activated and bound on the surface of tumor and normal cells. We have reported that the expression of a membrane-type-1-matrix metalloproteinase (MT1-MMP) induces activation of progelatinase A. Here we demonstrate that the expression of MT1-MMP in COS-1 cells induces cell-surface binding of progelatinase A which is consequently processed to an intermediate form. Processing from the intermediate to the fully active form is dependent on the gelatinase A concentration. These results suggest that the cell-surface binding concentrates the gelatinase A intermediate form locally to allow ...

The membrane-type matrix metalloproteinases (MT-MMPs) are a subclass of the matrix metalloproteinase (MMP) family which uniquely possess a C-terminal transmembrane domain and are initiators of an activation cascade for progelatinase A (MMP-2). Recent studies have shown that they can also efficiently directly degrade a number of matrix macromolecules. We now show that cells expressing MT1-MMP on their cell surfaces cause subjacent proteolysis of a gelatin film and that this proteolysis is inhibited by TIMP-2 but not by TIMP-1. These data indicate that expression of MT1-MMP on the cell surface may lead to both progelatinase A activation and extracellular matrix degradation.

Membrane-type 1 matrix metalloproteinase (MT1- MMP) localizes at the front of migrating cells and degrades the extracellular matrix barrier during cancer invasion. However, it is poorly understood how the polarized distribution of MT1-MMP at the migration front is regulated. Here, we demonstrate that MT1-MMP forms a complex with CD44H via the hemopexin-like (PEX) domain. A mutant MT1-MMP lacking the PEX domain failed to bind CD44H and did not localize at the lamellipodia. The cytoplasmic tail of CD44H, which comprises interfaces that associate with the actin cytoskeleton, was important for its localization at lamellipodia. Overexpression of a CD44H mutant lacking the cytoplasmic tail also prevented MT1-MMP from localizing at the lamellipodia. Modulation of F-actin with cytochalasin D revealed that both CD44H and MT1-MMP co-localize closely with the actin cytoskeleton, dependent on the cytoplasmic tail of CD44H. Thus, CD44H appears to act as a linker that connects MT1-MMP to the actin cytoskeleton and to

Membrane type-1 matrix metalloproteinase (MT1-MMP) is an activator of soluble MMP-2. The activity of both MMPs is regulated by their physiological inhibitor TIMP-2. An MT1-MMP/MMP-2/TIMP-2 axis plays a key role in the invasive behavior of many cell types. Despite its importance, epigenetic control of this pro-invasive axis is insufficiently studied, and, as a result, its modification in a rational and clinically beneficial manner is exceedingly difficult. Therefore, we performed an epigenetic analysis of the MT1-MMP, MMP-2, and TIMP-2 gene promoters in highly migratory glioblastoma cells and in low migratory breast carcinoma MCF-7 cells. We determined, for the first time, that the epigenetic control leading to the ...

Background: Akt is a critical molecule in several signal transduction pathways involved in vascular responses. Membrane type 1-matrix metalloproteinase (MT1-MMP), a membrane-anchored MMP, functions as a signaling molecule in addition to a proteolytic enzyme.. Hypothesis: Akt cooperates with MT1-MMP in tumor necrosis factor (TNF)-alpha-induced signaling pathways of vascular responses including endothelial dysfunction and haemostasis.. Methods and Results: TNF-alpha (10 ng/mL) induced a transient increase in Akt phosphorylation within 15 minutes, followed by the profound decrease of Akt phosphorylation and the increase in MT1-MMP activity within 60 minutes, in cultured human aortic endothelial cells (ECs). To demonstrate the role of MT1-MMP for Akt signaling pathway in TNF-alpha-stimulated ECs, we used siRNA to knockdown MT1-MMP protein in ECs. Silencing of MT1-MMP reversed TNF-alpha-triggered transient upregulation of Akt phosohorylation within 15 minutes and the downregulation within 60 minutes, ...

Matrix metalloproteinases (MMPs), a family of zinc-dependent endopeptidases implicated in tumor invasion and metastasis, must undergo zymogen activation prior to expressing any proteolytic activity. Although the cysteine-switch model predicts the well-established autoactivation process, approximately 40% of the known MMPs possess a conserved RXKR motif between their pro- and catalytic domains and, thus, could be activated directly by members of the proprotein convertase family. To further understand this process, we analyzed the activation of proMT3-MMP as a model system. We demonstrated that the conversion of MT3-MMP zymogen into active form is dependent on both the furin-type convertase activity and the R(116)RKR motif. Consistently, MT3-MMP was colocalized with furin in the trans-Golgi network by confocal microscopy. However, neither furin activity nor its recognition site in MT3-MMP is required for the observed colocalization. In fact, the colocalization pattern remains intact, even in the presence

Pericellular proteolysis of the extracellular matrix by membrane type 1-matrix metalloproteinase (MT1-MMP) confers tumor cells with the ability to proliferate within three-dimensional (3D) matrices and sustains tumor growth in mice. In this study, we show that in addition to its matrix-degrading activity, phosphorylation of MT1-MMP on its unique tyrosine residue located within its cytoplasmic sequence (Tyr573) may also participate to these processes. Fibrosarcoma cells expressing a proteolytically active but non-phosphorylable mutant of MT1-MMP showed a markedly reduced proliferation rate when embedded within 3D type I collagen matrices, this antiproliferative effect being correlated with arrest in the G0/G1 phase of the cell cycle. Impaired tyrosine phosphorylation of MT1-MMP also inhibits anchorage-independent growth of HT-1080 cells in soft agar as well as their invasion of collagen barriers, two prominent attributes of tumor cells, suggesting a broad inhibitory effect of the MT1-MMP mutant ...

Background: Pressure-overload causes left ventricular (LV) remodeling with one of the structural milestones of this process being extracellular matrix remodeling and fibrosis. While the regulation of matrix metalloproteinases (MMPs) likely plays a role in this process, the induction and mechanistic role of specific MMPs is poorly understood. Recent in-vivo studies have suggested that the transmembrane MMP, MT1-MMP can actually induce a profibrotic process and thereby effect matrix remodeling and fibrosis in PO. This study tested the hypothesis that in-vivo induction of MT1-promoter activity and expression occurs with PO.. Methods: MT1-MMP promoter activity (MT1-PROM act) was measured by generating a transgenic mouse (FVB; full length human MT1-MMP promoter ligated to the firefly luciferase gene). MT1-MMP PROM reporter mice underwent PO (4 weeks transverse aortic constriction n = 13) and were compared to non-banded controls (n = 10). In-vivo MT1-PROM act was quantified by luciferase mRNA ...

Membrane type 1 matrix metalloproteinase (MT1-MMP) is a potent modulator of the pericellular environment and promotes tumor cell invasion and proliferation in many types of tumor. The activation of proMMP-2 and processing of collagen I by MT1-MMP have been thought to be important for its tumor-promoting function. These activities can be inhibited by mutant forms of MT1-MMP lacking the catalytic domain. However, the effect of such dominant-negative mutants has never been evaluated in vivo. Various mutants lacking the catalytic domain (dCAT) were prepared and confirmed to inhibit MT1-MMP activity in human fibrosarcoma HT1080 cells, and tumor cells expressing these mutants were implanted s.c. into nude mice to monitor tumor formation. Only the membrane-anchored form of a dCAT construct through the transmembrane domain [dCAT(1)] showed potent antitumor activity not only in HT1080 cells but also in gastric carcinoma MKN28 and MKN45 cells expressing MT1-MMP. A soluble form of dCAT lacking the transmembrane

3531 Lysophosphatidic acid (LPA) functions as a powerful mitogen and also as a stimulator of membrane vesicle shedding in ovarian cancer cells in vitro. These shed vesicles contain cell surface associated antigens such as β1-integrin, Membrane Type-1 Metalloproteinase (MT1-MMP) and Epidermal Growth Factor Receptor (EGFR). LPA engagement of the LPA receptor promotes transactivation of the EGFR. In this study we evaluate the functional roles of ovarian cancer derived membrane vesicles and examine their effect in the immediate tumor microenvironment. Epithelial ovarian carcinoma DOV13 cells were stimulated with 80 μM LPA to induce vesicle shedding. Membrane vesicles were isolated through differential centrifugation of the LPA-stimulated conditioned media. Vesicle composition was analyzed by western blot analysis, fluorescent immunostaining and gel zymography.

We previously reported that deficiency of membrane-type five matrix metalloproteinase (MT5-MMP) prevents amyloid pathology in the cortex and hippocampus of 5xFAD mice, and ameliorates the functional outcome. We have now investigated whether the integrity of another important area affected in Alzheimers disease (AD), the frontal cortex, was also preserved upon MT5-MMP deficiency in 4-month old mice at prodromal stages of the pathology. We used the olfactory H-maze (OHM) to show that learning impairment associated with dysfunctions of the frontal cortex in 5xFAD was prevented in bigenic 5xFAD/MT5-MMP(-/-) mice. The latter exhibited concomitant drastic reductions of amyloid beta peptide (Aβ) assemblies (soluble, oligomeric and fibrillary) and its immediate precursor, C99. Simultaneously, astrocyte reactivity and tumor necrosis factor alpha (TNF-α) levels were also lowered. Moreover, MT5-MMP deficiency induced a decrease in N-terminal soluble fragments of amyloid precursor protein (APP), ...

EndoMT and EMT share many of the same regulators, with members of the TGFβ superfamily being arguably the most prominent players.

AdhIL13 injected in naïve knee joints results in 1000 pg/ml hIL-13 after 1 day, and increased to 3000 pg/ml detected at days 2, 3 and 7. Surprisingly, IL-13 did not diminish joint inflammation, because the influx of inflammatory cells was similar in the Addel70 and AdhIL13 group. MMP-mediated VDIPEN expression was not found 1 day after ICA onset because of the early time point. At day 3, IL-13 overexpression resulted in a twofold reduction in VDIPEN expression and a threefold reduction at day 7, compared with the control group. This decrease might be the result of a declined production of MMPs. However, the mRNA level of MMP-3 was comparable between the two groups, whereas MMP-12 and MMP-13 mRNA levels were three times higher in the IL-13 group. ...

The diaphragm pump includes a housing having an opening defined at one end. A diaphragm is attached to the housing and extends over the opening. An inlet is defined in the housing for receiving a fluid and a driving element is attached to the housing and in driving engagement with the diaphragm to vibrate the diaphragm. An orifice is defined in the diaphragm to permit a discharge of the fluid therethrough when the diaphragm is in vibration. A spring is disposed within the housing for biasing a plunger towards the diaphragm so that the plunger sealingly engages the diaphragm.

Proteolytic degradation of the extracellular matrix (ECM) is one intrinsic property of metastatic tumor cells to breach tissue barriers and to disseminate into different tissues. This process is initiated by the formation of invadopodia, which are actin-driven, finger-like membrane protrusions. Yet, …
