Abstract
The tissue inhibitor of metalloproteinase (TIMP) family, including TIMP-2, regulates the activity of multifunctional metalloproteinases in pathogenesis of melanoma. The Wnt/β-catenin pathway is constitutively activated and plays a critical role in melanoma progression. However, the relationship between TIMP-2 expression and β-catenin activity is still unclear. We hypothesize that TIMP-2 over expression inhibits the activation of the Wnt/β-catenin pathway in melanoma cells. Protein expression, distribution, and transcriptional activity of β-catenin were assayed in established stable melanoma cell lines: parental A2058 expressing, A2058 T2-1 over-expressing (T2-1), and A2058 T2R-7 under-expressing (T2R-7) TIMP-2. Compared to T2-1 cells at the basal level, T2R-7 showed significantly lower amount protein and weaker immunofluorescence staining of β-catenin. This regulation is through posttranslational level via ubiquitination. Functionally, proliferation and cell growth were lower in T2R-7 compared to A2058 and T2-1. Lithium treatment was used to mimics activation of the Wnt/β-catenin pathway. In T2R-7 cells under-expressing TIMP2, lithium significantly increased total β-catenin, nuclear β-catenin, and its downstream protein phosphor-c-Myc (S62). Nuclear β-catenin staining was enhanced in T2R-7. Beta-catenin transcriptional activity and cell proliferation were also increased significantly. Axins inhibit β-catenin pathway via GSK-3 β. We further found the ratio of p-GSK-3 β (S9) to β-catenin and protein levels of Axins were significantly lower, whereas downstream Wnt 11 was high in T2R-7 treated with lithium. Collectively, the high level of TIMP-2 protein inhibits the activation of the Wnt/β-catenin pathway, thus suppressing proliferation. Insights in the molecular mechanisms of TIMP-2 may provide promising opportunities for anti-proliferative therapeutic intervention.

Abstract
Angiogenesis is a complex phenomenon that involves interaction between growth factors/cytokines and their receptors, and proteolytic enzymes and their inhibitors, which, in addition to and in accordance with their main roles, act together during this multistep process. cancer angiogenesis is specific, because the same factors that enable angiogenesis are involved in the process of carcinogenesis. the aim of this review was to analyze the current knowledge regarding the significance of selected biomarkers in cancer angiogenesis, with emphasis on their prognostic value in the circulation.

Abstract
BACKGROUND Previous studies have shown that TIMP-2 overexpression is a useful therapeutic tool for inhibiting tumor growth and invasion in animals. However, it has not been reported whether genetic manipulation for TIMP-2 overexpression can induce an inhibitory effect on spontaneous metastasis from the primary tumor site to other organs such as lungs or lymph nodes in an animal model. METHODS The present studies describe the effects of retrovirus-mediated TIMP-2 gene transfer into human breast cancer cell lines on the in vitro invasion of the tumor cells or the in vivo growth in nude mouse. Here we also used retroviral-mediated TIMP-2 overexpression by intratumoral injection for suppression of metastasis in human breast carcinoma established in the mammary fat pad of nude mice. RESULTS As expected, overexpression of TIMP-2 inhibited matrix metalloprotenase (MMP) activity and invasion of the tumor cells. Also, the growth rate of tumors grafted with the breast cancer cells transduced with the retrovirus vector encoding TIMP-2 cDNA was significantly slower than the growth rate of tumors grafted with the breast cancer cells transduced with a control retrovirus vector. Furthermore, single intratumoral injection of the TIMP-2 retrovirus-producing cells into human breast tumor tissue established in mammary fat pads of nude mice showed a dramatic decrease in size and number of lung metastatic tumors. CONCLUSIONS Retrovirus-mediated TIMP-2 gene transfer into human breast cancer cells is able to down-regulate invasion and show that tumor-derived angiogenesis is reduced. In this model, retroviral-mediated transduction of TIMP-2 cDNA into a limited population of human tumor cells inhibits tumor growth and prevents distant pulmonary metastasis. These results indicate that it may not be necessary to deliver and express these genes in every single tumor cell as long as the level of expression in a limited number of transduced cells is sufficient to prevent the excessive breakdown of the extracellular matrix.

Abstract
Matrix metalloproteinases (MMPs) appear to play a key role in the development and progression of human malignancies. MMPs mediate the destruction of the extracellular matrix, which is an important early step in tumor invasion and metastasis. Growing evidence suggests that MMPs also have angiogenic activity and participate in the early stages of tumorigenesis and primary tumor growth. Investigations in experimental animal models have confirmed the importance of MMPs in the pathogenesis of colorectal cancer, and studies in humans show a direct association between increased MMP expression and tumor invasiveness, development of metastases, and shortened survival. In this review, the physiologic role of MMPs in normal tissues is examined and data supporting the role of MMPs in the pathogenesis of colorectal cancer are reviewed. The results of clinical trials with MMP inhibitors in colorectal cancer and promising areas for future investigation are also discussed.

Abstract
Matrix metalloproteinases (MMPs) are proteolytic enzymes that degrade components of the extracellular matrix (ECM) and basement membrane. They play a critical role in many physiological and pathological processes, such as tumor metastasis. The original concept-that MMP activity during metastasis is restricted solely to invasion of the basement membrane and destruction of ECM components-has been modified to encompass multiple aspects of tumor progression: tumor establishment, growth, angiogenesis, intravasation, extravasation, and almost all metastatic steps. Moreover, the role of tissue inhibitors of matrix metalloproteinases (TIMPs), originally believed to exhibit anti-invasion properties solely by virtue of their inhibition of MMPs, has been extended to include their multiple biological effects, such as growth promotion. In thyroid neoplasia as well, MMPs, in particular MMP-2, seem to be associated with metastatic potential. It would seem that similar and divergent patterns regulate MMP and TIMP gene expression in benign and malignant human thyrocytes, in many instances in agreement with the concept of MMPs playing the role of stimulating, and TIMPs inhibiting cell invasion.

Abstract
This review concentrates on how the major component of extracellular matrix, collagen, is catabolized. This process is important in a number of aspects of orthodontics since matrix is constantly turning over, the rate of which differs in embryogenesis, ageing, disease, and physiological processes, such as orthodontic tooth movement. It is not the purpose of this review to consider each process in detail. The aim is to give a clear account of the matrix metalloproteinases (a major family of proteinases) including their classification, properties, and functions.

Abstract
Matrix metalloproteinases (MMPs) play a critical role in the development of hemangioma-like vascular tumors in mice injected with murine eEnd.1 endothelioma cells. The current study was designed to (a) characterize the presence of MMPs in the vascular tumor, (b) define whether these MMPs originate from the transformed cells or from the recruited stromal cells and (c) study the stimulatory effect of eEnd.1 cells on the production of MMPs by endothelial cells. Several gelatinases were present in the eEnd.1 tumor extract, including latent and activated MMP-2 (72-kDa gelatinase A, EC 3.4.24. 24) and MMP-9 (92-kDa gelatinase B, EC 3.4.24.35). Immunohistochemical analysis of the tumor revealed focal reactivity for MMP-2. No gelatinase was produced by cultured eEnd.1 cells, or by six of nine related endothelioma cell lines, suggesting that stroma cells, particularly endothelial cells recruited by the tumor cells, rather than eEnd.1 cells themselves, are the source of the gelatinases observed in the tumors in vivo. The conditioned medium of eEnd.1 cells stimulated the release of MMP-2 and MMP-1 (interstitial collagenase, EC 3.4.24.7) by endothelial cells, but not of the inhibitor TIMP-2. The increased production of MMP-2 and MMP-1, observed at the protein level (zymogram and Western blot analysis), occurred through a posttranscriptional mechanism, since no increase in mRNA was observed and the stimulation was not prevented by inhibitors of protein synthesis. The inhibitory effects of monensin and brefeldin A, inhibitors of protein secretion, and the decrease in cell-associated MMP-2 in stimulated endothelial cells indicated that regulation occurred mostly at the level of protease secretion. MMPs are known to be regulated at different levels; this study indicates that, in endothelial cells, the stimulation of MMPs can also occur at the level of secretion, a mechanism that provides a rapid mobilization of these crucial enzymes in the early phases of angiogenesis.

Abstract
Previous studies have shown a correlation between the production of certain matrix metalloproteinases (MMPs), especially the gelatinases, by malignant tumors and the progression of these cancers as they invade and metastasize through the extracellular matrix and basement membranes. However, very few of these studies examined this relationship in human oral cancer in vivo, and none addressed the issue of how combinations of the MMPs may further enhance tumor progression. To determine which MMPs are produced in vivo by human oral cancers, we used specific anti-human-MMP antibodies and immunocytochemistry (ICC) methods to examine oral cancer tissue specimens from 20 surgery patients. The ICC data indicated that 72-kDa (72K-GL) and 92-kDa gelatinases (92K-GL) were produced in vivo by discreet clusters of tumor cells and by stromal fibroblasts, vascular endothelial cells (72K-GL), and PMNs (92K-GL). Some stromal fibroblasts near the tumors also appeared to produce fibroblast-type collagenase (FIB-CL), a finding confirmed by Western blot analysis of media conditioned by oral tumor explant cultures. ICC results indicated that 5 of the 20 tumors coincidentally produced all three MMPs. To examine how the two gelatinases and FIB-CL may interact in vitro to degrade fibrillar type I collagen, a major structural component of the extracellular matrix, we used a modified FIB-CL activity assay. Combinations of the gelatinases and FIB-CL were incubated with a 3H-collagen substrate, with the results compared with the combination of stromelysin-1 (SL-1, a superactivator of FIB-CL) and FIB-CL. 92K-GL caused a nine-fold increase in collagenase activity, equivalent to SL-1, while 72K-GL produced a four-fold increase. These results indicate that human oral cancers produce 92K-GL, 72K-GL, and FIB-CL in vivo and that the gelatinases and FIB-CL cooperate to enhance collagen degradation greatly in vitro.

Abstract
The progression of a tumor cell from one of benign delimited proliferation to invasive and metastatic growth is the major cause of poor clinical outcome of cancer patients. Recent research has revealed that this complex process requires many components for successful dissemination and growth of the tumor cell at secondary sites. These include angiogenesis, enhanced extracellular matrix degradation via tumor and host-secreted proteases, tumor cell migration, and modulation of tumor cell adhesion. Each individual component is multifaceted and is discussed within this review with respect to historical and recent findings. The identification of components and their interrelationship have yielded new therapeutic targets leading to the development of agents that may prove effective in the treatment of cancer and its metastatic progression.

Abstract
The matrix metalloproteinases (MMPs) are a family of at least fifteen secreted and membrane-bound zinc-endopeptidases. Collectively, these enzymes can degrade all of the components of the extracellular matrix, including fibrallar and non-fibrallar collagens, fibronectin, laminin and basement membrane glycoproteins. MMPs are thought to be essential for the diverse invasive processes of angiogenesis and tumor metastasis. Numerous studies have shown that there is a close association between expression of various members of the MMP family by tumors and their proliferative and invasive behavior and metastatic potential. In some of human cancers a positive correlation has also been demonstrated between the intensity of new blood vessel growth (angiogenesis) and the likelihood of developing metastases. Thus, control of MMP activity in these two different contexts has generated considerable interest as a possible therapeutic target. The tissue inhibitors of metalloproteinases (TIMPs) are naturally occurring proteins that specifically inhibit matrix metalloproteinases, thus maintaining balance between matrix destruction and formation. An imbalance between MMPs and the associated TIMPs may play a significant role in the invasive phenotype of malignant tumors. TIMP-1 has been shown to inhibit tumor-induced angiogenesis in experimental systems. These findings raised the possibility of using an agent that affects expression or activity of MMPs as an anti-cancer therapy. TIMPs are probably not suitable for pharmacologic applications due to their short half-life in vivo. Batimastat (BB-94) and marimastat (BB-2516) are synthetic, low-molecular weight MMP inhibitors. They have a collagen-mimicking hydroxamate structure, which facilitates chelation of the zinc ion in the active site of the MMPs. These compounds inhibit MMPs potently and specifically. Batimastat was the first synthetic MMP inhibitor studied in humans with advanced malignancies, but its usefulness has been limited by extremely poor water solubility, which required intraperitoneal administration of the drug as a detergent emulsion. Marimastat belongs to a second generation of MMP inhibitors. In contrast to batimastat, marimastat is orally available. Both of these agents are currently in Phase I/II trials in US, Europe and Canada. Some other new agents, currently in clinical trials, have been shown to inhibit MMP production. Bryostatins, naturally occurring macrocyclic lactones, have both in vitro and in vivo activity in numerous murine and human tumors. In culture, bryostatin-1 has been shown to induce differentiation and halt the growth of several malignant cell lines. While the exact mechanism responsible for anti-tumor activity is unclear, an initial event in the action of bryostatin-1 is activation of protein kinase C (PKC), followed by its down regulation. Bryostatin-1 does not directly affect the activity of MMPs, but it can inhibit the production of MMP-1, 3, 9, 10 and 11 by inhibiting PKC. TIMP-1 levels could also be modulated by bryostatin-1, as it is encoded by a PKC responsive gene.

Abstract
Arterial smooth muscle cells (SMCs) are in a quiescent growth state under normal physiological conditions, but they can be stimulated to proliferate and migrate from one tissue compartment to another if the vessel is injured. This response might require a selective and focal increase in tissue degradation, which might be mediated through the increased production of matrix metalloproteinases (MMPs). Blockade of MMP activity might therefore inhibit the SMC response to injury. To test this hypothesis, we developed clones of rat SMCs that overexpress baboon tissue inhibitor of matrix metalloproteinase-I (TIMP-1), using retrovirally mediated gene transfer, and characterized the functional capacity of these cells in vitro and in vivo. SMCs transduced with the TIMP-1 vector (LTSN) grew more slowly and also migrated through a gel matrix in a Boyden chamber assay more slowly than the vector alone (LXSN) cells. The conditioned medium from LTSN cells completely inhibited the platelet-derived growth factor-BB-induced migration of normal SMCs across a matrix-coated filter, while the LXSN cell conditioned medium had no effect. The inhibitor activity in the LTSN conditioned medium could be neutralized with an antibody to TIMP-1. In vivo, local overexpression of TIMP-1 using LTSN cells implanted onto balloon-injured rat carotid artery inhibited intimal hyperplasia. Neutralizing antibodies against TIMP-1 suppressed the effect of LTSN cell seeding on intimal thickening. These data support the conclusion that the process of SMC activation leading to a thickened intima is dependent on MMP activity and that TIMP-1 could be utilized to inhibit this process.

Abstract
Invasion of malignant cells requires altered cellular interaction with extracellular matrix. Integrin-type cell adhesion receptors play an important role in this process. Integrin-related cell biological phenomena explain cancer cell migration, and recent developments in the field have made it possible to propose that integrins are also involved in the penetration through basement membranes and other molecular barriers. Finally, malignant melanoma has been used here as an example to speculate on the function of each integrin in light of information from different experimental models.

Abstract
Malignant human melanoma cells produce many matrix-degrading enzymes, including plasminogen activators and matrix metalloproteinases. These enzymes have substrate specificity for different components of ECM and most of them have been demonstrated to contribute to melanoma cell-mediated dissolution of matrices and to melanoma cell invasion. The degradation of complex matrices in vitro requires the cooperation of proteases with specificity for glycoproteins and collagens. The contribution of proteases to spontaneous melanoma metastasis was studied by overexpressing specific protease inhibitors in human melanoma cells. Overexpression of PAI-2 inhibited the spread of distant metastasis indicating a role for uPA/plasmin in melanoma invasion. Overexpression of TIMP-2, in contrast, reduced the growth rate of subcutaneous tumors, but did not inhibit metastasis, indicating that MMP activities promote melanoma growth in the skin and may not be required for metastatic dissemination. Thus, uPA and MMP activities are involved in different processes, but they both contribute to melanoma malignancy.
