The active forms of all of the matrix metalloproteinases (MMPs) are inhibited by a family of specific inhibitors, the tissue inhibitors of metalloproteinases (TIMPs). Inhibition represents a major level of control of MMP activity. A detailed knowledge of the mechanisms controlling TIMP gene expression is therefore important. We have isolated a genomic clone of the human TIMP-1 gene. A 3 kbp XbaI fragment has been sequenced; this fragment contains 1718 bp 5′ flanking sequences, exon 1, a 929 bp intron 1 and part of exon 2. Computer analysis reveals 10 consensus sequences for Sp1, six for activating protein 1 (AP-1), six for polyoma enhancer A3 (PEA3), 12 for AP-2 and five CCAAT boxes. The region hybridizing with a murine TIMP-1 promoter fragment has been subcloned and analysed further. RNase protection identifies six transcription start points, making exon 1 up to 48 bp in length. Transient transfection of promoter-chloramphenicol O-acetyltransferase reporter constructs into primary human ...
The tissue inhibitors of metalloproteinases (TIMPs) are endogenous inhibitors of the matrix metalloproteinases (MMPs), enzymes that play central roles in the degradation of extracellular matrix components. The balance between MMPs and TIMPs is important in the maintenance of tissues, and its disruption affects tissue homoeostasis. Four related TIMPs (TIMP-1 to TIMP-4) can each form a complex with MMPs in a 1:1 stoichiometry with high affinity, but their inhibitory activities towards different MMPs are not particularly selective. The three-dimensional structures of TIMP-MMP complexes reveal that TIMPs have an extended ridge structure that slots into the active site of MMPs. Mutation of three separate residues in the ridge, at positions 2, 4 and 68 in the amino acid sequence of the N-terminal inhibitory domain of TIMP-1 (N-TIMP-1), separately and in combination has produced N-TIMP-1 variants with higher binding affinity and specificity for individual MMPs. TIMP-3 is unique in that it inhibits not only
Tissue inhibitors of metalloproteinases (TIMPs) inhibit matrix metalloproteinases (MMPs) by forming a 1:1 stoichiometric complex, but the inhibition mechanism of these inhibitors is not known. Here we have investigated the reactive site of TIMP-1 by its proteinase susceptibility before and after forming a complex with MMP-3 (stromelysin 1). When TIMP-1 was allowed to react with human neutrophil elastase, its inhibitory activity was destroyed. This resulted from cleavage of the Val69-Cys70 bond. However, cleavage of this bond by neutrophil elastase was prevented when TIMP-1 formed a complex with the catalytic domain of MMP-3, and full TIMP-1 activity was restored after dissociation of the complex at pH 3.0 in the presence of EDTA. These results indicate that the region around Val69 closely associates with an active MMP. The three-dimensional structure of the N-terminal domain of TIMP-2 elucidated by NMR studies [Williamson, Martorell, Carr, Murphy, Docherty, Freedman and Feeney (1994) ...
The protocol describes a novel, rapid, and no-wash one-step immunoassay for highly sensitive and direct detection of the complexes between matrix metalloproteinases (MMPs) and their tissue inhibitor of metalloproteinases (TIMPs) based on AlphaLISA® technology. We describe two procedures: (i) one approach is used to analyze MMP-9-TIMP-1 interactions using recombinant human MMP-9 with its corresponding recombinant human TIMP-1 inhibitor and (ii) the second approach is used to analyze native or endogenous MMP-9-TIMP-1 protein interactions in samples of human plasma. Evaluating native MMP-9-TIMP-1 complexes using this approach avoids the use of indirect calculations of the MMP-9/TIMP-1 ratio for which independent MMP-9 and TIMP-1 quantifications by two conventional ELISAs are needed. The MMP-9-TIMP-1 AlphaLISA® assay is quick, highly simplified, and cost-effective and can be completed in less than 3 h. Moreover, the assay has great potential for use in basic and preclinical research as it allows direct

Are matrix metalloproteinases and their inhibitors reliable diagnosis biomarkers and attractive therapeutic targets in endometriosis? Patrick Henriet, Khin Su Mon, Etienne Marbaix De Duve Institute, Université catholique de Louvain, Brussels, Belgium Abstract: Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are expressed in the human endometrium during the menstrual cycle, in particular to induce substantial extracellular matrix breakdown underlying menstruation. Endometriosis (EM) is characterized by the presence of endometrial tissue at ectopic locations. Because EM is thought to often develop from retrograde menstruation followed by implantation of menstrual tissue fragments at ectopic sites, endometrial MMPs and TIMPs were rapidly suspected as contributors to EM development and progression, generating hope for their use as biomarkers to facilitate EM diagnosis and as potential targets for developing new therapies against EM. Here, we not only summarize a

As their name implies, matrix metalloproteinases are thought to be responsible for the turnover and degradation of the extracellular matrix. However, matrix degradation is neither the sole nor the main function of these proteinases. Indeed, as we discuss here, recent findings indicate that matrix metalloproteinases act on pro-inflammatory cytokines, chemokines and other proteins to regulate varied aspects of inflammation and immunity.
A tissue inhibitor of metalloproteinases (TIMP)-1 was isolated from human polymorphonuclear leukocytes (PMNL) in a complex with latent 95-kDa gelatinase (matrixmetalloproteinase, MMP-9). It was separated from the enzyme by gel fitration in the presence of SDS. Using a competitive ELISA procedure, we determined that 10% of the isolated gelatinase was complexed with TIMP-1. The presence of the inhibitor in isolated PMNL could also be demonstrated by indirect immunofluorescence using a specific antibody against TIMP-1. Cellular mRNA was isolated from PMNL, which were highly purified by separation via formylMet-Leu-Pro-stimulated chemotactic migration in a Boyden chamber. Using reverse-transcription PCR and Northern blotting, TIMP-1 mRNA was shown to be present in PMNL, suggesting that these cells are also capable of synthesizing TIMP-1 ...
MMPs constitute part of a superfamily of metalloproteinases with conserved catalytic domain which become activated upon cleavage.2,8 MMP-9 and MMP-2 belong to the family of gelatinases because of their unique ability to degrade gelatin and are distinct from other families of MMPs, such as collagenases (MMP-1, MMP-8, and MMP-13), which can degrade collagens I, II, and III; stromeolysin (MMP-3, MMP-10, and MMP-11), which cannot degrade collagen I but can degrade fibronectin; laminins; and proteoglycans.2 These have a crucial role in ECM turnover and integrity in tissues and have been studied in various ocular diseases, including glaucoma.1-4,9 They also are important for cytokine regulation, which is vital for a multitude of processes involved in cell survival and functions. This mandates tight regulation of MMP functions and levels at multiple levels, such as transcription activation, posttranscriptional or epigenetic regulations, and MMP clearance/inhibition by tissue inhibitor of MMPs ...

TIMP-3 (Tissue inhibitor of metalloproteinases 3) is a secreted extracellular matrix protein, metalloprotease inhibitor. It forms complexes with metalloproteinases (such as collagenases) and irreversibly inactivates them by binding to their catalytic zinc cofactor. TIMP-3 is critical to the maintenance of tissue homeostasis by suppressing the proliferation of quiescent tissues in response to angiogenic factors and by inhibiting protease activity in tissues undergoing remodelling of the extracellular matrix. Defects in TIMP-3 are the cause of Sorsby fundus dystrophy (SFD). SFD is a rare autosomal dominant macular disorder with an age of onset in the fourth decade. It is characterized by loss of central vision from subretinal neovascularization and atrophy of the ocular tissues. Generally, macular disciform degeneration develops in the patients eye within 6 months to 6 years ...
The simplest interpretation of our in vitro studies is that increased expression of the MMP-9 proenzyme leads to the formation of active enzyme, which, in turn, degrades type IV collagen, leading to amnion cell apoptosis. Alternative interpretations include the possibility that the increased proMMP-9 sequestered endogenous tissue inhibitors of me-talloproteinases, leading to increased activities of […] ...

Tumor necrosis factor-alpha is released from cells by a proteolytic cleavage. Previous work suggested that a specific, non-matrix metalloproteinase carries out this cleavage, but matrix metalloproteinases have also been implicated. In this paper, we report that none of the matrix metalloproteinases tested cleaved peptide substrates as specifically as the non-matrix metalloproteinase. A matrix metalloproteinase did process tumor necrosis factor-alpha extracted from COS cells, but neither tissue inhibitor of metalloproteinases-1 nor -2 blocked tumor necrosis factor-alpha processing by human monocytes. Moreover, tissue inhibitor of metalloproteinases-1 had at most a partial effect on the in vivo release of the cytokine in mice. We conclude that a non-matrix metalloproteinase is the major physiological tumor necrosis factor-alpha convertase.

The proteoglycan aggrecan is an important major component of cartilage matrix that gives articular cartilage the ability to withstand compression. Increased breakdown of aggrecan is associated with the development of arthritis and is considered to be catalyzed by aggrecanases, members of the ADAM-TS family of metalloproteinases. Four endogenous tissue inhibitors of metalloproteinases (TIMPs) regulate the activities of functional matrix metalloproteinases (MMPs), enzymes that degrade most components of connective tissue, but no endogenous factors responsible for the regulation of aggrecanases have been found. We show here that the N-terminal inhibitory domain of TIMP-3, a member of the TIMP family that has functional properties distinct from other TIMPs, is a strong inhibitor of human aggrecanases 1 and 2, with K(i) values in the subnanomolar range. This truncated inhibitor, which lacks the C-terminal domain that is responsible for interactions with molecules other than active metalloproteinases, is

Matrix metalloproteinases in impaired wound healing Fabio Sabino, Ulrich auf dem Keller Institute of Molecular Health Sciences, Eidgenössische Technische Hochschule (ETH) Zürich, Zürich, Switzerland Abstract: Cutaneous wound healing is a complex tissue response that requires a coordinated interplay of multiple cells in orchestrated biological processes to finally re-establish the skin's barrier function upon injury. Proteolytic enzymes and in particular matrix metalloproteinases (MMPs) contribute to all phases of the healing process by regulating immune cell influx, facilitating migration of fibroblasts and keratinocytes, and remodeling of the scar tissue. As a result of these pleiotropic functions in the healing skin wound, uncontrolled activities of MMPs are associated with impaired wound healing, a growing health problem in Western countries due to increased life expectancies and rising rates of underlying diseases, such as diabetes. However, detailed mechanisms have been only

Matrix metalloproteinases (MMPs) are the enzymes which are directly involved in metastasis. Under physiological conditions MMPs are involved in such processes as embryogenesis, angiogenesis, cyclic changes in endometrium, wound healing and platelet aggregation. There is evidence that MMPs activity changes in many pathological conditions, including tumor disease, inflammatory and the degenera- tive diseases of nervous system. In cancer MMPs regulate growth and cancer-cell proliferation, metastasis, angiogenesis and the immune response to cancer. Gelatinase A (MMP-2) and gelatinase B (MMP-9) play an important role in cancer, because of their ability to degrade type IV collagen. The collagen type IV is the major component of basement membrane (BM). Loss of the continuity in BM structure determines the beginning of the cancer cell migration from primary tumor and creation of remote metastasis.. ...
The human tissue inhibitor of metalloproteinases (TIMP) is a glycoprotein with a molecular weight of 28,000. It appears to be ubiquitous in human mesoderm tissues and has previously been shown to be identical to the collagenase inhibitor isolated from human skin fibroblasts. TIMP inhibits type I- and IV-specific collagenases and other neutral metalloen-doproteinases that may be responsible for the degradation of extracellular matrix in tumor cell metastasis. In this work we have utilized recombinant human TIMP (rTIMP) obtained by expression of its cDNA gene (Carmichael et al., Proc. Natl. Acad. Sci. USA, 83: 2407, 1986). The rTIMP is shown to have similar inhibition properties as natural TIMP against human skin fibroblast collagenase. In an in vitro amnion invasion assay system, rTIMP inhibited the invasion of B16-F10 murine melanoma cells through the human amniotic membrane at an identical concentration to that reported previously for natural TIMP. The mechanism by which rTIMP inhibits amniotic ...
Tissue inhibitors of metalloproteinases (TIMPs) are a family of closely related proteins that inhibit matrix metalloproteinases (MMPs). In the central nervous system (CNS), TIMPs 2, 3, and 4 are constitutively expressed at high levels, whereas TIMP1 can be induced by various stimuli. Here, we studied the effects of constitutive expression of TIMP1 in the CNS in transgenic mice. Transgene expression started prenatally and persisted throughout lifetime at high levels. Since MMP activity has been implicated in CNS development, in proper function of the adult CNS, and in inflammatory disorders, we investigated Timp1-induced CNS alterations. Despite sufficient MMP inhibition, high expressor transgenic mice had a normal phenotype. The absence of compensatory up-regulation of MMP genes in the CNS of Timp1 transgenic mice indicates that development, learning, and memory functions do not require the entire MMP arsenal. To elucidate the effects of strong Timp1 expression in CNS inflammation, we induced ...
To the Editor:. It was with great interest that I read the article by Tuomainen et al1 recently published in this journal on the association of matrix metalloproteinase (MMP)-8 and tissue inhibitor of MMP-1 (TIMP-1) with cardiovascular diseases. The authors measured both analytes in serum and concluded from their results that serum MMP-8 and the ratio of MMP-8 to TIMP-1 were useful biomarkers with prognostic and diagnostic significances in men with cardiovascular disease, especially in those with prevalent or subclinical arteriosclerosis.1 Although I am not experienced in this clinical field, I believe it might be meaningful to make the readership of this journal aware of an important issue that was obviously not considered by Tuomainen et al in their study design. It refers to the influence of blood sample processing as essential precondition for the correct determination of circulating MMPs and TIMPs in peripheral blood. The effect of the type of blood sample, either collected as serum with or ...

Extracellular matrix provides the microenvironment for the cells and serves as a tissue scaffold, guiding cell migration during embryonic development and wound repair. Beyond that, it also functions as the repository and modulator of growth factors and cytokines, and therefore is responsible for transmitting environmental signals to the cells.. Among proteases, the matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) family are often associated with ECM degradation and remodeling. The inhibitors of MMPs are called tissue inhibitors of metalloproteinases (TIMPs), which are comprised of TIMP-1, TIMP-2, TIMP-3, and TIMP-4. The interactions between these proteases and their inhibitors play important roles in cell morphogenesis, angiogenesis, tissue remodeling, tissue repair, tumor metastasis, cirrhosis, and arthritis. The features of the ECM are determined both by the cells that produce the matrix and by the cells growing in it. QIAGENs ...

Using a competitive PCR technique we have established a system for rapid and simultaneous measurement of multiple genes involved in the metabolism of the ECM within a single colonic biopsy. To gain further insight into their biological function in inflammatory bowel disease we analysed relative mRNA expression of collagen type III, matrix metalloproteinases MMP-1 and MMP-2, their respective major activators MMP-3 and MMP-14, as well as their physiological inhibitors TIMP-1 and TIMP-2 in endoscopic biopsies from inflamed and non-inflamed colon of IBD patients.. We observed that mRNA expression of all MMPs was significantly increased in inflamed compared with non-inflamed colonic mucosa of these patients. This increase was most pronounced in ulcerated colonic mucosa. By performing westerns blots, increased expression of MMP-1, MMP-2, and MMP-3 was also demonstrated at the protein level, which supports previous in vitro studies showing a close correlation between mRNA and protein expression of ...

Purpose: While antiretroviral therapy (ART) has improved the quality of life and survival of HIV-1-infected patients, HIV-1-associated neurocognitive disorders (HAND) remain a major problem in over 30% of cases. All forms of HAND are associated with CNS inflammation. Astrocytes, the principal type of glial cells, are involved in signaling, homeostasis, and repair during CNS pathology. Some astrocytes become non-productively infected by HIV-1. The balance between matrix metalloproteinases (MMP) and their inhibitors must be tightly regulated during CNS inflammation. In the brain, tissue inhibitor of MMPs (TIMP)-1 protects human neurons from HIV-1-induced apoptosis and is mainly produced by astrocytes. Further, astrocyte TIMP-1 is differentially regulated during acute and chronic IL-1β-activation. However, the direct or indirect effects of astrocyte HIV-1 protein expression on TIMP-1 regulation are not well studied. Here, we investigated downstream effects of HIV-1 Tat and gp120 expression in astrocytes

Solitary cell recordings display that this ICAM-5 ectodomain stimulates a rise in the rate of recurrence, however, not the amplitude, of AMPA mini excitatory post synaptic currents (mEPSCs). With biotinylation and precipitation assays, we also display that this ICAM-5 ectodomain stimulates a rise in membrane degrees of GluA1, however, not GluA2, AMPAR subunits. Furthermore, we observe an ICAM-5 connected upsurge in ...

2. Matrix Metalloproteinases (MMP) - are responsible for breaking down proteins. They are found throughout the body but in skin their role is to breakdown and recycle the skin matrix of the dermis, specifically collagen and elastin.
