Abstract
The objective of this study was to investigate the roles of matrix metalloproteinases (MMP-2, MMP-9) and cyclooxygenase-2 (COX-2) in the pathogenesis of vocal fold polyps (VFPs). In this study, 20 VFPs and 8 normal vocal fold (VF) specimens were obtained from subjects undergoing surgery. Staining intensities were semiquantitatively assessed and statistically analyzed. Significant increases were observed in the expressions of MMP-2, MMP-9, and COX-2 in stromal spindle cells (P=0.00) and vascular wall (P=0.04, P=0.00, P=0.00) of VFPs compared with normal VFs. MMP-2 expression in surface epithelium basal cells (P=0.00) of VFPs showed enhancement compared with normal vocal folds, whereas MMP-9 and COX-2 expressions showed no significant differences. Our study showed that gelatinases and COX-2 may play a role in the development of VFPs. This is the first study to document the expression of gelatinases and COX-2 in VFPs.

Abstract
The disorganization of E-cadherin/catenin complexes and the overexpression of matrix metalloproteinases (MMPs) are frequently involved in the capacity of epithelial cells to acquire an invasive phenotype. The functional link between E-cadherin and MMPs was studied by transfecting invasive bronchial BZR tumor cells with human E-cadherin cDNA. Using different in vitro (cell dispersion, modified Boyden chamber) and in vivo assays (human airway epithelial xenograft), we showed that E-cadherin-positive clones displayed a decrease of invasive abilities. As shown by immunoprecipitation, the re-expressed E-cadherin was able to sequestrate one part of free cytoplasmic beta-catenin in BZR cells. The decrease of beta-catenin transcriptional activity in E-cadherin-transfected clones was demonstrated using the TOP-FLASH reporter construct. Finally, we observed a decrease of MMP-1, MMP-3, MMP-9, and MT1-MMP, both at the mRNA and at the protein levels, in E-cadherin-positive clones whereas no changes in MMP-2, TIMP-1, or TIMP-2 were observed when compared with control clones. Moreover, zymography analysis revealed a loss of MMP-2 activation ability in E-cadherin-positive clones treated with the concanavalin A lectin. These data demonstrate a direct role of E-cadherin/catenin complex organization in the regulation of MMPs and suggest an implication of this regulation in the expression of an invasive phenotype by bronchial tumor cells.

Abstract
We investigated the influence of estrogenic and antiestrogenic treatment on proteolytic activity--especially on MMP-2 and MMP-13--in the RUCA-I transplantable endometrial tumor model. Morphological studies demonstrate that RUCA-I cells are forming highly differentiated gland-like structures by remodelling and invading the underlying ECM. Estrogens upregulate the mRNA levels of MMP-2 and MMP-13 in the rat uterus. Treatment with the pure antiestrogen ICI 182,780 results in the downregulation of MMP-2 and MMP-13 mRNA. The same regulation for MMP-13 mRNA is found in vitro in RUCA-I cells. In contrast, in the transplantation tumor, the mRNA level of MMP-13 is repressed by estrogens and induced by ICI 182,780. MMP-2 mRNA is not regulated by hormones in the transplantation tumor and in RUCA-I cells. The divergent regulation suggests a varying influence of cell-cell-, cell-extracellular matrix interactions and soluble factors.

Abstract
Loss of E-cadherin/catenin mediated cell-cell adhesion and overexpression of matrix metalloproteinases (MMPs) are largely involved in tumor invasion. It has been recently shown that high levels of a soluble 80 kDa fragment of E-cadherin, resulting from a cleavage by MMPs, are found in serum and in urine from cancer patients. Additionally, this soluble E-cadherin (sE-CAD) promotes cell invasion into chick heart and into collagen type I gels. The aim of our study was to examine the mechanism of sE-CAD-induced cell invasion. Since MMPs play a crucial role in invasion, we looked for induction of MMPs by sE-CAD in noninvasive human lung tumor cells 16HBE. An induction of MMP-2, MMP-9 and MT1-MMP expression was observed both at the mRNA and at the protein level in the presence of sE-CAD (in conditioned medium form or in E-cadherin HAV peptide form). No induction of MMP-1, -3 and -7 or variation of the levels of their inhibitors, TIMP-1 and TIMP-2, were detected. The biologic relevance of the sE-CAD-induced MMP upregulation was tested by demonstrating that sE-CAD promotes in vitro cell invasion in a modified Boyden chamber assay. These data provide new insight into mechanisms of tumor invasion by ectodomain shedding of the cell-cell adhesion molecule E-cadherin.

Abstract
Crucial event in the metastasis of cancer cells is the secretion of matrix metalloproteinases (MMPs), which are responsible for the degradation of extracellular matrix (ECM). Among them, matrix metalloproteinase-2 (MMP-2) is a gelatinase, which degrades basement membrane type-IV collagen. Immunohistochemistry was performed to detect MMP-2 protein in 135 infiltrative breast carcinomas. MMP-2 was studied along with clinicopathological parameters (tumor size, histological type, nuclear and histological grade, stage, lymph node status, ER, and PR), patients' survival and tissue inhibitor metalloproteinase-2 (TIMP-2), Ki-67, and p53 proteins. MMP-2 immunoreactivity was detected in the cytoplasm in cancer cells in 102 (75.6%) and in both tumor and tumor stromal cells in 37 (27.4%) of 135 cases respectively. MMP-2 reactivity in cancer cells displayed a statistically significant association with tumor size > 2 cm (p = 0.022). In tumor stromal cells a strong parallel association was observed between the expression of MMP-2 and TIMP-2 (p = 0.015), while an inverse correlation was found between MMP-2 and both Ki-67 and p53 (p = 0.033 and p = 0.034 respectively). In the subgroup with negative lymph nodes MMP-2 was also inversely associated with p53 in cancer cells (p = 0.045). Finally a statistically significant association was revealed using Kaplan-Meier and Cox's proportional hazard regression model between the MMP-2/TIMP-2 phenotype and patients' better survival (p = 0.021). Our results point out the strong relation between MMP-2 and TIMP-2 and the effect of the MMP-2/TIMP-2 phenotype in the patients' overall survival. The inverse correlation between MMP-2 and both Ki-67 and p53 can be explained by the potential inhibition of MMP-2 by TIMP-2. These results suggest the necessity of further investigation.

Abstract
Extracellular matrix metalloproteinase inducer (EMMPRIN), a glycoprotein present on the cancer cell plasma membrane, enhances fibroblast synthesis of matrix metalloproteinases (MMPs). The demonstration that peritumoral fibroblasts synthesize most of the MMPs in human tumors rather than the cancer cells themselves has ignited interest in the role of EMMPRIN in tumor dissemination. In this report we have demonstrated a role for EMMPRIN in cancer progression. Human MDA-MB-436 breast cancer cells, which are tumorigenic but slow growing in vivo, were transfected with EMMPRIN cDNA and injected orthotopically into mammary tissue of female NCr nu/nu mice. Green fluorescent protein was used to visualize metastases. In three experiments, breast cancer cell clones transfected with EMMPRIN cDNA were considerably more tumorigenic and invasive than plasmid-transfected cancer cells. Increased gelatinase A and gelatinase B expression (demonstrated by in situ hybridization and gelatin substrate zymography) was demonstrated in EMMPRIN-enhanced tumors. In contrast to de novo breast cancers in humans, human tumors transplanted into mice elicited minimal stromal or inflammatory cell reactions. Based on these experimental studies and our previous demonstration that EMMPRIN is prominently displayed in human cancer tissue, we propose that EMMPRIN plays an important role in cancer progression by increasing synthesis of MMPs.

Abstract
Tumor cells interact with stromal cells via soluble or cell-bound factors stimulating the production of matrix metalloproteinases (MMPs), a group of enzymes largely involved in the extracellular matrix (ECM) remodeling in tumor invasion. Among these factors, extracellular matrix metalloproteinase inducer (EMMPRIN) has been shown to stimulate in vitro the fibroblast production of various MMPs such as interstitial collagenase (MMP-1), stromelysin-1 (MMP-3), and gelatinase A (MMP-2). In this study, the EMMPRIN protein was detected by immunohistochemistry prominently in malignant proliferations of the breast and the lung. It was present at the surface of both tumor epithelial and peritumor stromal cells. Because previous studies have reported that stromal cells do not express EMMPRIN mRNAs, it is very likely that EMMPRIN is bound to stromal cells via a specific receptor. Moreover, our observations also demonstrated that the same peritumor stromal cells strongly express MMP-2. Our results show that EMMPRIN is an important factor in tumor progression by causing tumor-associated stromal cells to increase their MMP-2 production, thus facilitating tumor invasion and neoangiogenesis.

Abstract
Wear debris of polyethylene prosthetic components is known to induce a host granulomatous reaction which recruits numerous macrophages and multinucleated giant cells. By releasing cellular mediators of a nonspecific inflammatory reaction, activated phagocytic cells are thought to play a key role in osteolysis leading to aseptic loosening of the prosthesis. Matrix metalloproteinases (MMPs) have been implicated in this destructive process by their ability to degrade extracellular matrix components of bone and adjacent connective tissue. To investigate the roles of gelatinase A, its activator MT1-MMP, and the MMP inhibitors TIMP-1 and TIMP-2 in aseptic loosening of polyethylene prostheses, immunohistochemistry (IHC) and in situ hybridization (ISH) were performed on periprosthetic pseudosynovial interface tissues. Gelatinase A and MT1-MMP were strongly detected immunohistochemically in macrophages and multinucleated giant cells in contact with polyethylene wear debris. In contrast to MT1-MMP, gelatinase A mRNAs were not found in phagocytic cells but in surrounding fibroblasts, thereby suggesting cooperation between macrophages and fibroblasts in this process. While TIMP-1 was expressed essentially in hyperplastic pseudosynoviocytes as assessed by IHC and ISH, TIMP-2, MT1-MMP, and gelatinase A were colocalized in phagocytic cells. These data support the concept of progelatinase A activation involving a trimolecular complex (MT1-MMP-TIMP-2-gelatinase A) mechanism. Thus, this study demonstrated that gelatinase A and its activator might contribute to the aseptic loosening of polyethylene prostheses.

Abstract
We have previously reported that concanavalin A (ConA)-induced MMP-2 activation involves both transcriptional and non-transcriptional mechanisms. Here we examined the effects of calcium influx on MT1-MMP expression and MMP-2 activation in MDA-MB-231 cells. The calcium ionophore ionomycin caused a dose-dependent inhibition of ConA-induced MMP-2 activation, but had no effect on MT1-MMP mRNA levels. However, Western analysis revealed an accumulation of pro-MT1-MMP (63 kDa), indicating that ionomycin blocked the conversion of pro-MT1-MMP protein to the active 60 kDa form. This suggests that increased calcium levels inhibit the processing of MT1-MMP. This finding may help to elucidate the mechanism(s) which regulates MT1-MMP activation.
