TY - JOUR. T1 - Cell surface binding and activation of gelatinase A induced by expression of membrane-type-1-matrix metalloproteinase (MT1-MMP). AU - Sato, Hiroshi. AU - Takino, Takahisa. AU - Kinoshita, Takeshi. AU - Imai, Kazushi. AU - Okada, Yasunori. AU - Stetler Stevenson, William G.. AU - Seiki, Motoharu. PY - 1996/5/6. Y1 - 1996/5/6. 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 ...

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 ...
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 ...

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
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, ...

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 ...

Mô tả: Membrane-type 5-matrix metalloproteinase (MT5-MMP) is a proteinase mainly expressed in the nervous system with emerging roles in brain pathophysiology. The implication of MT5-MMP in Alzheimers disease (AD), notably its interplay with the amyloidogenic process, remains elusive. Accordingly, we crossed the genetically engineered 5xFAD mouse model of AD with MT5-MMP-deficient mice and examined the impact of MT5-MMP deficiency in bigenic 5xFAD/MT5-MMP(-/-) mice. At early stages (4 months) of the pathology, the levels of amyloid beta peptide (Aβ) and its amyloid precursor protein (APP) C-terminal fragment C99 were largely reduced in the cortex and hippocampus of 5xFAD/MT5-MMP(-/-), compared to 5xFAD mice. Reduced amyloidosis in bigenic mice was concomitant with decreased glial reactivity and interleukin-1β (IL-1β) levels, and the preservation of long-term potentiation (LTP) and spatial learning, without changes in the activity of α-, β- and γ-secretases. The positive impact of... ...
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) 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

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
We present a molecular dissection of the functional domains of cortactin relevant for invadopodia formation and function. In addition, through the expression of cortactin forms mutated in the residues previously found to be phosphorylated in vitro, we suggest the involvement of different kinases in the control of the ECM degradation machinery through the regulation of cortactin phosphorylation.. The overexpression of mutant or deleted forms of cortactin that are unable to bind the Arp2/3 complex, induces a substantial decrease in the ability of the cells to form invadopodia and hence degrade the ECM. In addition, the SH3 domain of cortactin, known to bind a number of relevant proteins such as N-WASP and dynamin 2, is also essential for invadopodia formation and ECM degradation. This is at variance with a recent report suggesting that the cortactin N-terminus is not required for invadopodia formation (Webb et al., 2007). A possible explanation is that the study was based on constitutively active ...

Most studies on fibroblast motility have been carried out using cells on the surfaces of culture dishes. In situ, however, the environment for fibroblasts is the three-dimensional extracellular matrix. In the current research, we studied the morphology and motility of human fibroblasts embedded in floating collagen matrices at a cell density below that required for global matrix remodeling (i.e., contraction). Under these conditions, cells were observed to project and retract a dendritic network of extensions. These extensions contained microtubule cores with actin concentrated at the tips resembling growth cones. Platelet-derived growth factor promoted formation of the network; lysophosphatidic acid ...
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. The invasive potential of DOV13 cells, normal ovarian epithelial cells (IOSE), normal uterine smooth muscle (utSMC) and uterine ...
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), ...

One of the hallmarks of human pancreatic ductal adenocarcinoma (PDAC) is its pronounced type I collagen-rich fibrotic reaction. Although recent reports have shown that the fibrotic reaction can limit the efficacy of gemcitabine chemotherapy, the underlying mechanisms remain poorly understood. In this article, we show that the type I collagen allows PDAC cells to override checkpoint arrest induced by gemcitabine. Relative to cells grown on tissue culture plastic, PDAC cells grown in 3-dimensional collagen microenvironment have minimal Chk1 phosphorylation and continue to proliferate in the presence of gemcitabine. Collagen increases membrane type 1 matrix metalloproteinase (MT1-MMP)-dependent ERK1/2 phosphorylation to limit the effect of gemcitabine. Collagen also increases MT1-MMP-dependent high mobility group A2 (HMGA2) expression, a nonhistone DNA-binding nuclear protein involved in chromatin remodeling and gene transcription, to attenuate the effect of gemcitabine. Overexpression of MT1-MMP ...

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 ...
Demethoxycurcumin (DMC) is one of the main active compounds of curcuminoids found in turmeric powder, which is used as a spice in Asian cooking and traditional medicine. Recent studies reveal that DMC has several biological activities including anti-inflammation and anti-cancer activities. However, the molecular mechanism by which DMC has anti-metastasis activity in breast cancer cells remains poorly understood. Here, we report for the first time that DMC inhibited adhesion, migration and invasion of MDA-MB-231 human breast cancer cells. For cancer cell migration and invasion, extracellular matrix (ECM) degradation processes are required. MDA-MB-231 cells treated with DMC had decreased levels of ECM degradation-associated proteins including matrix metalloproteinase-9 (MMP-9), membrane type-1 matrix metalloproteinase (MT1-MMP), urokinase plasminogen activator (uPA) and uPA receptor (uPAR), while the level of uPA inhibitor (PAI-1) was up-regulated. Moreover, DMC also reduced the expression of ...
Ovarian cancer is an highly metastatic disease characterized by ascites formation and diffuse i.p. adhesion, invasion, and metastasis. Levels of lysophosphatidic acid (LPA) are elevated in the plasma of patients with ovarian carcinoma, including 90% of patients with stage I disease, suggesting that LPA may promote early events in ovarian carcinoma dissemination. Expression of matrix metalloproteinases (MMPs) is also up-regulated in ovarian cancer tissues and ascites, and numerous studies have provided evidence for a direct role of MMPs in i.p. invasion and metastasis. Using three-dimensional type I collagen cultures or immobilized beta1 integrin subunit-specific antibodies, we previously demonstrated that beta1 integrin clustering promotes activation of proMMP-2 and processing of membrane type 1 MMP in ovarian cancer cells (S. M. Ellerbroek et al., Cancer Res., 59: 1635-1641, 1999). In the current study, the effect of LPA on MMP expression and invasive activity was investigated. Treatment of ...
Glycosylation is an important and universal post-translational modification for many proteins, and regulates protein functions. However, simple and rapid methods to analyze glycans on individual proteins have not been available until recently. A new technique to analyze glycopeptides in a highly sensitive manner by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) using the liquid matrix 3AQ/CHCA was developed recently and we optimized this technique to analyze a small amount of transmembrane protein separated by SDS-PAGE.. We used the MALDI-MS method to evaluate glycosylation status of membrane-type 1 matrix metalloproteinase (MT1-MMP). Glycosylation of MT1-MMP is reported to modulate its protease activity and thereby to affect cancer cell invasion. After in-gel tryptic digestion of the protein, a single droplet of the digest was applied directly to the liquid matrix on a MALDI target plate. Concentration of hydrophilic glycopeptides within the central area occurred due ...

TOL19-001 reduces inflammation and MMP expression in monolayer cultures of tendon cells by C. Baugé et al. BMC Complementary and Alternative Medicine 2015; 15:217; doi 10.1186/s12906-015-0748-7.. Abstract. Background. Tendinopathies are tendon conditions associated with degeneration and disorganization of the matrix collagen fibers, tendon cells apoptosis and inflammation through up-regulation of proinflammatory cytokines, matrix metalloproteinase (MMP) expression, and prostaglandin E2 (PGE2) production. Currently, the pharmacological treatment is mainly based on non-steroidal anti-inflammatory drugs (NSAIDs) use and corticosteroid injections, which both can lead to numerous side effects for patients. TOL19-001 is a diet supplementary composed mostly of spirulina and glucosamine sulfate whose antioxidant properties could be helpful to treat tendinopathies while avoiding taking NSAIDs. In this study we developed an in vitro model of tendinopathy in order to evaluate the therapeutic potential of ...

Matrix Metalloproteinase 2: A secreted endopeptidase homologous with INTERSTITIAL COLLAGENASE, but which possesses an additional fibronectin-like domain.
The proteolytic processes used by normal or neoplastic cells to penetrate the fibrin deposits that surround wounds, inflammatory sites, or tumor foci have remained largely undefined (2-13). Given the efficiency with which plasmin degrades fibrin relative to other proteinases, it has been generally assumed that the plasminogen activator-plasminogen axis would serve as the sole determinant of invasive activity (5, 6, 11, 12). While plasmin can participate in fibrin-invasive events in vitro or in vivo (5, 6, 11, 12, 55), studies in plasminogen-deficient mice have demonstrated that alternate proteolytic systems exist that allow cells to readily infiltrate fibrin-rich tissues in pathophysiologic settings (e.g., references 9, 16-18, and 56). Coincident with these findings, increased awareness has focused on the fact that the substrate repertoire of MMPs can be extended from structural components of the "mature" extracellular matrix (i.e., collagens, elastins, glycoproteins, and proteoglycans) to ...
