Abstract
Normal epithelial cells exert their competitive advantage over RasV12-transformed cells and eliminate them into the apical lumen via cell competition. However, the internal or external factors that compromise cell competition and provoke carcinogenesis remain elusive. In this study, we examine the effect of sequential accumulation of gene mutations, mimicking multi-sequential carcinogenesis on RasV12-induced cell competition in intestinal epithelial tissues. Consequently, we find that the directionality of RasV12-cell extrusion in Wnt-activated epithelia is reversed, and transformed cells are delaminated into the basal lamina via non-cell autonomous MMP21 upregulation. Subsequently, diffusively infiltrating, transformed cells develop into highly invasive carcinomas. The elevated production of MMP21 is elicited partly through NF-κB signaling, blockage of which restores apical elimination of RasV12 cells. We further demonstrate that the NF-κB-MMP21 axis is significantly bolstered in early colorectal carcinoma in humans. Collectively, this study shows that cells with high mutational burdens exploit cell competition for their benefit by behaving as unfit cells, endowing them with an invasion advantage.

Abstract
BACKGROUND The activity of matrix metalloproteinases (MMPs) in degrading extracellular matrix is controlled by activation of proenzymes and inhibition of MMP tissue inhibitors (TIMPs). PATIENTS AND METHODS To assess the proteolytic cascade imbalance in malignancy progression, tissue expression and serum levels of MMP-2, MMP-9 and of their inhibitors TIMP-2 and TIMP-1 respectively were evaluated in 42 selected patients with high-grade osteosarcoma (OS). MMP-2, MMP-9, TIMP-2 and TIMP-1 were studied in biopsies by immunohistochemistry and in serum by ELISA test. Patients were subdivided into 3 groups according to their follow up: continuously disease-free, diagnosis of metastasis during follow-up, and metastasis at diagnosis. RESULTS Immunohistochemistry demonstrated an imbalance between MMPs and TIMPs, with a more evident role for MMP-9 than for MMP-2 in tumor progression. TIMP-1 inhibitor in plasma was higher in patients with osteosarcoma than in a control group. This high value of TIMP-1 was particularly evident in the group of patients who later developed metastases and/or local recurrences, and in those with metastases at diagnosis. INTERPRETATION Our findings confirm the protective action of TIMP-1, as MMP inhibitor, but also show its activity as a growth factor underlining its multifunctional role in OS.

Abstract
Matrix metalloproteinases (MMPs) degrade components of the extracellular matrix of the disc, but the presence of MMP-19 has not been explored. In other tissues, MMP-19 is known to act in proteolysis of the insulin-like growth factor (IGF) binding protein-3, thereby exposing this protein to make it available to influence cell behavior. MMP-19 also has been shown to inhibit capillary-like formation and thus play a role in the avascular nature of the disc. Using immunohistochemistry, normal discs from six subjects aged newborn through 10 years and 20 disc specimens from control donors or surgical patients aged 15-76 (mean age 40.2 years) were examined for immunolocalization of MMP-19; six Thompson grade I discs, five Thompson grade II, eight Thompson grade III, five Thompson grade IV, and one Thompson grade V discs were analyzed. The results indicate that in discs from young subjects, MMP-19 was uniformly localized in the outer annulus. In discs from adult donors and surgical patients, outer and inner annulus cells only occasionally showed MMP-19 localization. The greatest expression of MMP-19 was observed in young discs, and little expression was seen in older or degenerating discs. Because MMP-19 has been shown to regulate IGF-mediated proliferation in other tissues, its decline in the aging/degenerating disc may contribute to the age-related decrease in disc cell numbers.

Abstract
In degrading the extracellular matrix, matrix metalloproteinases (MMP) and the plasminogen activator (PA) system may play a critical role in extensive remodeling that occurs in the bovine mammary gland during development, lactation, and involution. Therefore, the aim of our study was to investigate the mRNA expression of MMP-1, MMP-2, MMP-14, MMP-19, tissue inhibitor of metalloproteinases (TIMP)-1, TIMP-2, urokinase-type PA, tissue-type PA, urokinase-type PA receptor, and PA inhibitor-1 by quantitative PCR and to localize with immunohistochemistry MMP-1, MMP-2, MMP-14, and TIMP-2 proteins in the bovine mammary gland during pubertal mammogenesis, lactogenesis, galactopoiesis, and involution. Expression of mRNA for each of the studied factors was relatively lower during galactopoiesis and early involution but was markedly increased during mammogenesis and late involution, 2 stages in which tissue remodeling is especially pronounced. The localization of proteins for MMP-1, MMP-14, and TIMP-2 showed a similar trend with strong staining intensity in cytoplasm of mammary duct and alveolar epithelial cells during pubertal mammogenesis and late involution. Interestingly, MMP-2 protein was localized only in the cytoplasm of endothelial cells during late involution. Our study demonstrated clearly that expression of extracellular matrix-degrading proteinases coincides with a concomitant expression of their inhibitors. High expression levels of MMP, TIMP, and PA family members seem to be a typical feature of the nonlactating mammary gland.

Abstract
BACKGROUND/AIM Because the pericapillary basement membrane in skeletal muscles of patients with chronic critical limb ischemia (CLI) is thickened, we determined the expression patterns of genes involved in collagen metabolism, using samples from 9 CLI patients, 4 patients with acute limb ischemia and 4 healthy controls. METHODS Gene array analysis, quantitative RT-PCR and semiquantitative grading of immunohistochemical reactivity were performed to determine mRNA/cDNA and protein concentrations. RESULTS In CLI patients compared to controls, cDNA levels of matrix metalloproteinase (MMP)-9 and MMP-19 were higher, collagen type IV chains A1 and A2, tissue inhibitor of matrix metalloproteinase (TIMP)-1 and TIMP-2 were similar and MMP-2 were lower. On the protein level, MMP-2, MMP-9, MMP-19 and TIMP-1 were more abundantly expressed. In skeletal muscles from patients with acute limb ischemia, cDNA and protein levels of MMP-9, MMP-19, collagen type IV chains, TIMP-1 and TIMP-2 were high. MMP-2 was elevated at the protein but decreased on the cDNA level. CONCLUSION Expression of basement membrane components in skeletal muscles of CLI and acute limb ischemia patients is altered, possibly contributing to the pathogenesis of peripheral arterial disease.

Abstract
Matrix metalloproteinase-19 (MMP-19), unlike other members of the MMP family, is expressed in basal keratinocytes of intact epidermis whereas keratinocytes in suprabasal and higher epidermal layers express this enzyme only during cutaneous disorders. As the activity of MMP-19 effects proliferation, migration, and adhesion of keratinocytes we examined whether transcription factors involved in keratinocyte differentiation repress the expression of MMP-19. Using luciferase reporter assays, POU transcription factors Tst-1 (Oct-6) and Skn-1a (Oct-11) markedly downregulated the activity of MMP-19 promoter in COS-7 cells and HaCaT keratinocytes. Tst-1 alone was able to inhibit 85% of the promoter activity. Skn-1a exhibited a weak inhibitory effect although it synergistically increased effects of Tst-1. HaCaT cells stably transfected with Tst-1 showed a strong decrease of activity of MMP-19 promoter that correlated with suppression of MMP-19, cytokeratin 14 and 5, decreased cell proliferation, and altered expression of involucrin and loricrin. The expression of MMP-9 was also significantly reduced in Tst-1 expressing keratinocytes. MMP-2 was substantially affected during its activation whereas the expression of MMP-28 was unchanged. Our results suggest that Tst-1 and Skn-1a regulate expression of MMPs in keratinocytes and effect both the expression and activation of these proteolytic enzymes.

Abstract
Matrix metalloproteinases (MMPs) are proteases known for their capacity to degrade extracellular matrix (ECM) components. MMPs have been implicated in several central nervous system (CNS) diseases, including multiple sclerosis (MS). Microarray analysis has demonstrated significant increased mRNA levels of MMP-19 in chronic MS lesions, suggesting a role of MMP-19 in MS pathogenesis. Therefore, in this study, we investigated the expression pattern and cellular localization of MMP-19 protein in various well-characterized MS lesion stages. In normal control patient white matter, MMP-19 was constitutively expressed by microglia throughout the brain parenchyma, suggesting a physiological role for this MMP family member. Likewise, MMP-19 was expressed by microglia in (p)reactive MS lesions, albeit more intense. In highly active demyelinating MS lesions, parenchymal and perivascular myelin-laden macrophages were strongly immunoreactive for MMP-19, whereas reactive astrocytes were occasionally immunopositive. Astrocytes in chronic inactive lesions were weakly stained for MMP-19. In vitro, MMP-19 was expressed in cultures of primary human microglia, not in astrocyte cultures. As MMP-19 is able to degrade basement membrane constituents and other ECM proteins, it is conceivable that this relatively novel MMP family member contributes to MS pathology by remodelling the ECM of the CNS, thereby influencing leucocyte infiltration, axonal regeneration and astrogliosis.

Abstract
The objective of this study was to determine the spatial expression of matrix metalloproteinases (MMPs) and their physiologic inhibitors, the tissue inhibitor of MMP (TIMP)-3 and TIMP-4, in ovarian carcinoma compared to normal ovaries. Immunohistochemistry was carried out in this study. Tissue sections prepared from normal ovarian tissues from throughout the menstrual cycle (N = 20) and ovarian carcinomas (N = 45) characterized as stage I (N = 5), stage III/IV (N = 40) were immunostained using polyclonal antibodies to the latent and the active form of MMP-26, TIMP-3, and a monoclonal antibody to TIMP-4. Immunoreactive MMP-26, TIMP-3, and TIMP-4 were detected in all the ovarian cell types in normal and tumor tissues. In normal ovarian tissues, theca externa and luteal cells immunostained with high intensity for MMP-26 and TIMPs while theca/granulosa cell staining intensity increased as lutenization progressed. There was low immunostaining of the ovarian stromal and surface epithelial cells for MMP-26, with moderate staining for TIMPs. In the carcinoma specimens, cancer cells and vascular endothelial cells displayed the highest staining intensity compared to adjacent nontumor areas. The immunostaining intensity of MMP-26 and TIMP-3 increased with stage of tumor with the invading tumor cells displaying the strongest immunostaining. MMP-26, TIMP-3, and TIMP-4 are expressed in normal ovarian as well as ovarian tumors with elevated expression in the invasive tumor cells suggesting a potential role for MMP-26 in normal ovary and ovarian cancer biologic function.

Abstract
We have previously reported that endometrial mRNA expression of both tissue inhibitors of metalloproteinase-4 (TIMP-4) and matrix metalloproteinase-26 (MMP-26) peaks in the early secretory phase, which implies a role in implantation. The objective of this study was to compare the distribution of TIMP-4 and MMP-26 in endometrial tissue and uterine fluid over the menstrual cycle. Endometrial tissue was analysed with in situ hybridization and immunohistochemistry to localize mRNA and protein for TIMP-4 and MMP-26 in the same set of samples. TIMP-4 mRNA was quantified in separated stromal and epithelial cells using real-time PCR. Uterine fluid was analysed with western blotting. TIMP-4 mRNA was exclusively localized to the stroma, whereas MMP-26 mRNA was expressed by epithelial cells. TIMP-4 protein was only occasionally found in the stroma but was consistently present in granules of the apical part of luminal and glandular epithelial cells. TIMP-4, but not MMP-26, was demonstrated in uterine fluid. Thus, TIMP-4 is produced in the stroma only, secreted by stromal cells, taken up by epithelial cells, accumulated in apical granules and finally secreted to the uterine fluid. Maximal expression of MMP-26, and its strongest inhibitor TIMP-4, in the early and mid-secretory phase suggests a role during implantation. MMP-26 is stored in epithelial cells in its active form, is not released spontaneously and is controlled by TIMP-4 in both stroma and uterine fluid.

Abstract
MMPs are multifunctional enzymes capable of targeting the extracellular matrix, growth factors, cytokines and cell surface-associated adhesion and signaling receptors. The cellular localization and the activity of MMPs are tightly controlled at both the transcriptional and the post-transcriptional levels. Mislocalization and presentation in unconventional cellular compartments provide MMPs with an opportunity to cleave previously unidentified proteins. This review is focused on two, entirely different MMPs, one of which is membrane-tethered and another of which is soluble (MT1-MMP and MMP-26, respectively) from twenty four known human MMPs. Our recent studies determined that both of these enzymes functioned at unexpected cellular compartments and it was resulted in the identification of novel proteolytic pathways, whose significance we only partially comprehend as of this writing. It is reasonable, however, to hypothesize from these data that many individual MMPs perform in a similar manner and display a much broader range of functions compared to what we earlier thought.

Abstract
Among matrix metalloproteinases (MMP), MMP-19 displays unique structural features and tissue distribution. In contrast to most MMPs, MMP-19 is expressed in normal human epidermis and down-regulated during malignant transformation and dedifferentiation. The contribution of MMP-19 during tumor angiogenesis is presently unknown. In an attempt to give new insights into MMP-19 in vivo functions, angiogenic response of mutant mice lacking MMP-19 was analyzed after transplantation of murine malignant PDVA keratinocytes and after injection of Matrigel supplemented with basic fibroblast growth factor. In situ hybridization and immunohistochemical analysis revealed that MMP-19 is produced by host mesenchymal cells but not by endothelial capillary cells or CD11b-positive inflammatory cells. Based on a new computer-assisted method of quantification, we provide evidence that host MMP-19 deficiency was associated with an increased early angiogenic response. In addition, increased tumor invasion was observed in MMP-19-/- mice. We conclude that, in contrast to most MMPs that promote tumor progression, MMP-19 is a negative regulator of early steps of tumor angiogenesis and invasion. These data highlight the requirement to understand the individual functions of each MMP to improve anticancer strategies.

Abstract
BACKGROUND Tissue destruction associated with the progression of periodontal disease is caused by a cascade of host and microbial proteolytic enzymes. Host-derived matrix metalloproteinases (MMPs) play an important role in the degradation of the extracellular matrix. Leukolysin/membrane-type 6 (MT-6)/MMP-25, the latest member of the MT-MMP subgroup of the MMP family, is primarily expressed by neutrophils and involved in extracellular matrix turnover. Matrilysin-2/MMP-26 (endometase), a novel member of the matrilysin subgroup of the MMP family, can degrade the extracellular matrix, alpha1-antitrypsin, and activate pro-MMP-9. Our study aimed to examine the levels, molecular forms, and degrees of activation of MMP-25 and MMP-26 in gingival crevicular fluid (GCF) from patients with different periodontal diseases. METHODS A total of 105 subjects, 35 with generalized aggressive periodontitis (GAgP), 29 with chronic periodontitis (CP), 20 with gingivitis, and 21 periodontally healthy subjects, were included in this study. Periodontal status was evaluated by measuring probing depth, clinical attachment loss, presence of bleeding on probing, and plaque. GCF MMP-25 and MMP-26 levels were analyzed by computer-quantitated Western immunoblotting using specific antibodies. RESULTS The 57-kDa soluble pro-MMP-25 and 45- to 47-kDa active form of MMP-25 were detected by Western immunoblots in CP and GAgP GCF, and lesser levels of these soluble MMP-25 immunoreactive bands were detected in gingivitis GCF. An enhanced and similar degree of MMP-25 activation was found in GAgP, CP, and gingivitis groups. There were no detectable MMP-25 immunoreactivities in the healthy subjects' GCF. GAgP and CP groups had elevated GCF MMP-26 levels and degrees of activation compared to the gingivitis and healthy groups (P <0.008). The gingivitis group had higher GCF MMP-26 levels and degree of activation compared to the healthy group (P <0.008). CONCLUSIONS The present study demonstrated the presence of soluble or shed forms of MMP-25 and MMP-26 in GCF of patients with different periodontal diseases. Increased levels and activation of MMP-25 and MMP-26 in GCF are associated with an enhanced severity of periodontal inflammation, suggesting that these novel MMPs can participate in the progression of periodontal diseases. They may prove to be diagnostically useful and could be targets of medication in the future.

The matrixmetalloproteinase-19 (MMP-19) belongs to the superfamily of the zinc-dependent endopeptidases, which are secreted by cells and are involved in the remodeling of the extracellular matrix. The full-length protein consists of a signal peptide, a propeptide, a catalytic domain and a C-terminal hemopexin-like domain. For other members of this superfamily, the hemopexin-like domain has been described to be involved in substrate recognition. In this study, the hemoxpexin domain of MMP-19 was expressed in Escherichia coli, refolded, and purified. For structural characterization, circular dichroism and NMR spectroscopy were used. We show that the hemopexin-like domain of MMP-19 is able to bind calcium and this binding induces a conformational change and an increase in the thermal stability of the domain. MMP-19 promotes proliferation of keratinocytes by cleaving the insulin-like-growth factor binding protein-3, thereby causing the release of IGF-1, which is a potent growth factor for these cells. By plasmon resonance experiments, we show that the isolated hemopexin-like domain is able to bind to the insulin-like-growth factor binding protein-3. These results provide a basis for further structural investigations that could be used for the rational design of potential agonists and antagonists.

Abstract
Matrix metalloproteinases (MMPs) comprise a large group of endoproteinases that degrade all protein components of the extracellular matrix. Functionally, MMPs contribute to several different physiological as well as pathological conditions. The number of newly described MMPs has increased in recent years, although current knowledge about their expression pattern in various tissues remains incomplete. Here we analyzed the relative mRNA expression of the most recently described MMPs--MT5-MMP (MMP-24), MT6-MMP (MMP-25), MMP-27 and epilysin (MMP-28)--in a broad selection of rat tissues using real time-PCR. MMP-24 mRNA was found to be widely expressed with predominance in the central nervous system. MMP-25 mRNA, in contrast, exhibited peak expression levels in testis, kidney and skeletal muscle, differing from previously described distribution patterns in humans. mRNAs for MMP-27 and MMP-28 were generally expressed at a lower level. All four MMPs studied were detected at higher mRNA levels in bone and kidney, suggesting a possible role of these MMPs in physiological processes within these two organs. The present study highlights the differential distribution pattern of newly described MMPs among different tissues and underlines differences in the mRNA expression between different species.

Abstract
Estrogens have many cellular functions, including their interactions with estrogen receptors alpha and beta (ERalpha and ERbeta). Earlier, we determined that the estrogen-ER complex stimulates the transcriptional activity of the matrix metalloproteinase 26 (MMP-26) gene promoter. We then determined that ERbeta is susceptible to MMP-26 proteolysis whereas ERalpha is resistant to the protease. MMP-26 targets the NH(2)-terminal region of ERbeta coding for the divergent NH(2)-terminal A/B domain that is responsible for the ligand-independent transactivation function. As a result, MMP-26 proteolysis generates the COOH-terminal fragments of ERbeta. Immunohistochemical analysis of tissue microarrays derived from 121 cancer patients corroborated these data and revealed an inverse correlation between the ERalpha-dependent expression of MMP-26 and the levels of the intact ERbeta in breast carcinomas. MMP-26 is not expressed in normal mammary epithelium. The levels of MMP-26 are strongly up-regulated in ductal carcinoma in situ (DCIS). In the course of further disease progression through stages I to III, the expression of MMP-26 decreases. In contrast to many tumor-promoting MMPs, the expression of MMP-26 in DCIS correlated with a longer patient survival. Our data suggest the existence of an MMP-26-mediated intracellular pathway that targets ERbeta and that MMP-26, a novel and valuable cancer marker, contributes favorably to the survival of the ERalpha/beta-positive cohort of breast cancer patients.

Abstract
Matrix metalloproteinase 21 (MMP-21) and MMP-26 (matrilysin-2) are the two newest members of the human MMP gene family that have both been suggested to play an important role in epithelial tumor progression and to be regulated via the Wnt signaling pathway. We studied their expression in 34 esophageal squamous cell carcinomas and non-neoplastic epithelium. MMP-21 protein was detected in cancer cells and inflammatory cells at the invasive front. Its expression was associated with invasion, inflammation, apoptotic and well-differentiated areas of the tumors, but not with cell proliferation. Unlike MMP-21, MMP-26 protein was already upregulated in incipient invasion and its expression associated with regions of low differentiation being more sporadic at the invasive front. MMP-21 was detected basally in KYSE-30 and OE21 esophageal squamous cell carcinoma cells, while MMP-26 was absent. None of the several cytokines and matrices tested were capable of consistently upregulating MMP-21 or MMP-26 mRNA expression in these two cell lines. Our results suggest that during esophageal tumorigenesis, MMP-21 and MMP-26 have different, unique expression patterns both being tightly regulated and induced in the vicinity of inflammation. MMP-21 may provide a marker for differentiating tumor areas. The putative role of MMP-26 as a marker of dysplasia and incipient invasion warrants further studies.

Abstract
Epilysin, designated matrix metalloproteinase (MMP)-28, is the newest member of this family of proteases expressed by keratinocytes in response to an injury. MMP-28's physiological role and specific substrates are unknown, but its expression pattern suggests that it may serve a role in both tissue homeostasis and wound healing. The aim of this preliminary study was to observe the presence of MMP-28 protein in normotrophic and hypertrophic scars and to evaluate the effect of in vitro mechanical compression on its expression. Biopsies from normotrophic and hypertrophic scars resulting from burns were divided into two samples, one to be used as control (uncompressed) and the other to be compressed in an oxygenated organ chamber for 24 hours in the presence of a serum-free medium, using an electromechanical load transducer (stable pressure = 35 mmHg). Analysis of MMP-28 protein secretion, assessed by Western blot and beta-casein zymography in scar conditioned media, revealed that normotrophic scar did not release MMP-28 in any condition while hypertrophic scar released active MMP-28 both in control conditions and after compression. MMP-28 immunohistochemistry revealed a light protein presence in normotrophic scar keratinocytes and a strong MMP-28 positivity in hypertrophic scar keratinocytes in control conditions, while compression increased MMP-28 staining in normotrophic scar and induced a significant reduction of the protein presence in hypertrophic scar keratinocytes. As it has been suggested that MMP-28 may restructure the skin basal membrane (Saarialho-Kere et al., 2002), our data indicate that mechanical compression directly acts to modulate the remodeling phase of wound healing, altering release and activity of MMP-28 in hypertrophic scars.

Abstract
The expression of matrix metalloproteinases (MMPs) is frequently altered during malignant transformation. We examined the profile of three recently cloned MMPs, MMP-21, MMP-26, and MMP-28, in melanomas in vivo and in culture. Immunohistochemistry for MMPs-21, -26, -28, and -13 in melanoma specimens (27 nonmetastatic, 26 with nodal micrometastases, and 10 in situ melanomas) from 63 patients was performed. MMP-21 was expressed in melanoma cells in 29/53 cases, being more frequent in melanoma samples without micrometastases. Six out of ten in situ melanomas were positive, while five nevus samples were negative. MMP-26 and -28 were not generally expressed in melanoma cells. MMP-13 was detected in melanoma cells in 36/53 samples. MMP-21 was not found in sentinel nodes with metastases, while MMP-13 was seen in all of them. MMP-21 messenger RNA was variably expressed in all five melanoma cell lines investigated using reverse transcriptase-polymerase chain reaction. Our results suggest that expression of MMP-21 may serve as a marker of malignant transformation of melanocytes and does not associate with the presence of micrometastases.

Abstract
BACKGROUND The risk of squamous cell carcinoma (SCC) is significantly increased in chronic leg ulcers. Very little is known about the molecular pathogenesis of these tumours, which are often undiagnosed for a long time. As matrix metalloproteinases (MMPs) are implicated at all stages of tumorigenesis, we investigated whether the pattern of epithelial MMP expression can predict development of SCC from pseudoepitheliomatous hyperplasia of chronic wounds. METHODS Samples from nine patients with SCCs that had arisen in chronic wounds and 31 with venous leg ulcers were studied using immunohistochemistry for MMP-7, MMP-8, MMP-9, MMP-13, MMP-19 and the tumour suppressor p16. In situ hybridization was performed for MMP-1, MMP-3, MMP-7, MMP-12 and MMP-13. RESULTS MMP-7 was expressed by malignantly transformed epithelium, while it was absent from chronic wounds. MMP-9 was detected in the epithelium in both SCCs and chronic wounds. Epithelial MMP-13 expression was strong in SCC, but was absent in chronic wounds. MMP-12 was expressed in the epithelium in two SCCs, while macrophages were positive in chronic wounds. MMP-19 was induced in proliferating epithelium of wounds, but was absent from invasive areas of SCC. p16 was expressed by keratinocytes in half of the chronic wounds and at superficial margins of SCCs, while invasive areas were negative. CONCLUSIONS Our results suggest that epithelial expression of MMP-7, MMP-12 and MMP-13, but not that of MMP-1, MMP-3, MMP-8, MMP-9 and MMP-10, in chronic wounds provides a diagnostic clue for distinguishing SCCs from nonmalignant wounds. The loss of MMP-19 and p16 from the epithelium could aid in making the differential diagnosis between well-differentiated SCCs and nonmalignant chronic wounds.

Abstract
In this study we analyzed the proteolytic activity of MMP-19 and its impact on keratinocyte migration. In the HaCaT keratinocyte cell line overexpressing wild-type MMP-19 (HaCaT-WT), transmigration through fibrin and type IV collagen matrices was significantly increased compared to cells harboring a catalytically inactive mutant (HaCaT-EA). Studying the expression of MMP-19 in early stages of squamous cell cancer (SCC), we found co-localization of MMP-19 and laminin 5 at the invading tumor front but not in suprabasal epidermis of the tumor. Examination of laminin 5 processing revealed increased processing of the gamma2 chain in the medium and matrix of HaCaT-WT cells and degradation by recombinant human MMP-19 to 105-kDa and 80-kDa fragments. Parental HaCaT grown on the matrix of HaCaT-WT and HaCaT-EA cells displayed differential tyrosine phosphorylation. Using integrin blocking and stimulating antibodies we could attribute these differences to a shift from beta4-integrin-dependent signaling on the HaCaT-EA matrix toward alpha3-integrin-dependent signaling on the HaCaT-WT matrix. As a consequence, parental HaCaT showed increased migration on the matrix of HaCaT-WT cells. These data suggest that the MMP-19-dependent processing of the gamma2 chains leads to the integrin switch favoring epithelial migration and that MMP-19 actively participates in the early stages of SCC invasion.

Abstract
Matrix metalloproteinases (MMPs) and their tissue inhibitors play important roles in the remodeling of extracellular matrix (ECM). MMP-26, also called endometase or matrilysin-2, is a novel member of the MMP family. The present study was to investigate the temporal and spatial expression of MMP-26 mRNA in mouse uterus during the estrous cycle and early pregnancy by using in situ hybridization and semi-quantitative RT-PCR. In this study, MMP-26 mRNA was found to be localized to the luminal and glandular epithelium at proestrus and estrus, and the expression level was decreased significantly from metestrus to dioestrus. During pre-implantation period, MMP-26 mRNA was predominantly expressed in luminal and glandular epithelium at much higher level; whereas it switched to stroma during peri-implantation period, and also appeared in the blastocysts and the implantation sites. The results suggested that MMP-26 might play a role in the cycling changes of mouse uterus during the estrous cycle and embryo implantation.

Abstract
Matrilysin-2 (matrix metalloproteinase (MMP)-26) is a small protein of the MMP family expressed in some epithelial carcinomas and normal tissues. We studied its role in benign skin disorders characterized by epithelial proliferation, in wound repair, skin cancer, and regulation in keratinocyte (KC) cultures. MMP-26 is expressed by laminin-5-positive KC in the migrating area during wound repair, in benign skin disorders characterized by inflammation and microdisruptions of basement membrane, but in intact skin only in hair follicles. It was detected in occasional atypical KC in pre-malignant lesions but not in basal cell cancer islands. Although MMP-26 was expressed in grades I and II squamous cell cancers (SCC), it was not present in dedifferentiated grade III tumors. MMP-26 was neither co-expressed with its close homologue matrilysin-1 nor with the proliferation marker Ki-67. But in tissue samples it either co-localized or was detected in adjacent cells of same regions with the tumor suppressor p16. In KC and HaCaT cell cultures, 12-phorbol-13-myristate-acetate, epidermal growth factor, tumor necrosis factor-alpha, transforming growth factor-beta1, interleukin-1 (IL-1)beta, IL-6, insulin-like growth factor, gamma-IFN, retinoic acid, dexamethasone, four matrices or ras-transformation were unable to upregulate MMP-26 expression. The expression pattern of MMP-26 suggests that it may be upregulated in basal KC even without tumorigenesis because of altered cell-matrix interactions and inflammation and, unlike most MMP, becomes downregulated during histological dedifferentiation of SCC. Thus, lack of MMP-26 in SCC could be a marker of aggressive growth.

Abstract
The processes of implantation and placentation involve the degradation and remodeling of extracellular matrix, cellular proliferation, apoptosis, and differentiation. Evidence indicates that members of the matrix metalloproteinase (MMP) family play crucial roles in these processes. In the present study, we identified the expression and localization of MMP26/endometase/ matrilysin-2 in human placentae at different stages of gestation using methods of reverse transcriptase-polymerase chain reaction, in situ hybridization, and immunohistochemistry. MMP26 was widely localized to villous cytotrophoblast cells, syncytiotrophoblast cells, and to column trophoblasts during early pregnancy. The mRNA and protein level of MMP26 in chorionic villi was highest at Weeks 6-7, and decreased thereafter, reaching its lowest level at the second trimester. The mRNA level was significantly up-regulated in term placenta, while the immunoreactivity remained undetectable. Notably, intense expression of MMP26 was found in fetal nucleated red cells inside the villous capillaries during gestational Weeks 6-9. Strong expression of MMP26 mRNA was also demonstrated in fetal red cells isolated from the whole blood of fetuses at midpregnancy. The expression patterns of MMP26 in human placenta suggests complicated roles for MMP26 during the processes of placentation and hematopoiesis, perhaps working in concert with other members of the MMP family, such as MMP9.

Abstract
Proteases exert control over cell behavior and affect many biological processes by making proteolytic modification of regulatory proteins. The purpose of this paper is to describe novel, important functions of matrix metalloproteinase (MMP)-26. alpha1-Antitrypsin (AAT) is a serpin, the primary function of which is to regulate the activity of neutrophil/leukocyte elastase. Insufficient antiprotease activity because of AAT deficiency in the lungs is a contributing factor to early-onset emphysema. We recently discovered that AAT is efficiently cleaved by a novel metalloproteinase, MMP-26, which exhibits an unconventional PH(81)CGVPD Cys switch motif and is autocatalytically activated in cells and tissues. An elevated expression of MMP-26 in macrophages and polymorphonuclear leukocytes supports the functional role of MMP-26 in the AAT cleavage and inflammation. We have demonstrated a direct functional link of MMP-26 expression with an estrogen dependency and confirmed the presence of the estrogen-response element in the MMP-26 promoter. Immunostaining of tumor cell lines and biopsy specimen microarrays confirmed the existence of the inverse correlations of MMP-26 and AAT in cells/tissues. An expression of MMP-26 in the estrogen-dependent neoplasms is likely to contribute to the inactivation of AAT, to the follow-up liberation of the Ser protease activity, and because of these biochemical events, to promote matrix destruction and malignant progression. In summary, we hypothesize that MMP-26, by cleaving and inactivating the AAT serpin, operates as a unique functional link that regulates a coordinated interplay between Ser and metalloproteinases in estrogen-dependent neoplasms.

Abstract
The biological role of most proteases in vivo is largely unknown. Therefore, to develop robust techniques to analyze the protease degradome in cells and tissues and to elucidate their substrate degradomes we have developed a dedicated and complete human protease and inhibitor microarray that we have called the CLIP-CHIP Oligonucleotides (70-mers) for identifying all 715 human proteases, inactive homologs and inhibitors were spotted in triplicate onto glass slides with a dedicated subarray containing oligonucleotides for specific human breast carcinoma genes. Initial analyses revealed the elevated expression of a number of proteases in invasive ductal cell carcinoma including ADAMTS17, carboxypeptidases A5 and M, tryptase-gamma and matriptase-2. Matrix metalloproteinases (MMPs) showed a restricted expression pattern in both normal and cancerous breast tissues with most expressed at low levels. However, of the several MMPs expressed in significant quantities, the carcinoma samples showed only slightly elevated amounts other than for MMP-28 which was strongly elevated. To discover new protease substrates we developed a novel yeast two-hybrid approach we term 'inactive catalytic domain capture' (ICDC). Here, an inactive mutant protease catalytic domain lacking the propeptide was used as a yeast two hybrid bait to screen a human fibroblast cDNA library for interactor proteins as a substrate trap. Wnt-induced signaling protein-2 (WISP-2) was identified by ICDC and was biochemically confirmed as a new MMP substrate. In another approach we used isotope-coded affinity tag (ICAT) labeling with tandem mass spectrometry to quantitate the levels of secreted or shed extracellular proteins in MDA-MB-231 breast carcinoma cell cultures in the presence or absence of membrane type 1-MMP (MT1-MMP) overexpression. By this proteomic approach we identified and biochemically confirmed that IL-8, the serine protease inhibitor SLPI, the death receptor-6, pro-TNF-alpha and CTGF are novel substrates of MT1-MMP. The utility and quantitative nature of ICAT with MS/MS analysis as a new screen for protease substrate discovery based on detection of cleaved or shed substrate products should be readily adaptable to other classes of protease for assessing proteolytic function in a cellular context.

Abstract
OBJECTIVE To examine the expression pattern of matrix metalloproteinase-26 (MMP-26) mRNA and estrogen receptor-alpha (ER alpha) in normal, hyperplastic, premalignant and malignant endometrial tissue. DESIGN Experimental study. SETTING Department of Obstetrics and Gynecology of the Palacky University Medical School and University Hospital, Olomouc, Czech Republic, Department of Obstetrics and Gynecology, University Hospital, Lund, Sweden, Atherosclerosis Research Unit, King Gustav V Research Institute, Karolinska Hospital, Stockholm, Sweden. METHODS We studied MMP-26 mRNA and ER alpha in 36 normal, 7 hyperplastic, 6 premalignant and 19 malignant endometrial samples. Based on histological examination, all normal specimens were classified according to an ideal 28 day menstrual cycle as early, mid, and late proliferative phase, early, mid and late secretory phase and menstrual phase. Samples with hyperplasia were classified as simple or complex. Premalignant samples were represented by complex hyperplasia with atypia. Malignant samples were histologically classified as well, intermediately and poorly differentiated, respectively. Specimens were analyzed using in situ hybridization and real time PCR. ER alpha was localized by immunohistochemistry. RESULTS Epithelial MMP-26 mRNA expression was highest in the early secretory phase and in endometrial hyperplasia. Expression levels were low in the late secretory and menstrual phase and in malignant samples decreased gradually with dedifferentiation. Expression pattern of MMP-26 mRNA in normal, hyperplastic, premalignant and malignant endometrial tissue strongly co-variated with that of ER alpha. CONCLUSION Co-expression of MMP-26 and ER alpha in normal and pathological endometrial tissue suggests possible regulation of MMP-26 gene by estrogen.

Abstract
OBJECTIVES Necrotizing enterocolitis (NEC) is the most common gastrointestinal disease of premature infants characterized histologically by extensive tissue injury and inflammation. Matrix metalloproteinases (MMP) are involved in tissue remodeling and cell migration, both being important aspects of inflammatory disease. The aim of this study was to investigate whether MMPs play a role in the pathogenesis of NEC. METHODS Expression of MMP-1, -7, -9, -10, -12, -19 and -26 was studied using in situ hybridization/immunohistochemistry in samples intestinal tissue removed from 15 patients with NEC; in 7 of them control samples were obtained at closure of stomas. Six intestinal samples from patients with intestinal atresia and four samples of necrosis were also included in the material examined. Laminin-5 was immunostained to find migrating enterocytes and cytokeratin to delineate mucosal epithelium. RESULTS MMP-7 protein was upregulated in the epithelium of 12/18 NEC samples. MMP-26 was induced in stromal cells of 12/17 NEC specimens. Stromal expression was found for MMP-1 and -12 mRNAs in 7/18 samples. MMP-1 was also detected in the epithelium of regenerating areas. Both NEC and stoma samples expressed MMP-9 in inflammatory cells. Epithelial MMP-19 was downregulated in NEC. CONCLUSIONS Our results suggest that several MMPs may be major factors in tissue destruction and remodeling in NEC. Targeted inhibition of matrilysins, using synthetic MMP inhibitors or blockers of their signal transduction pathways, may represent a novel therapeutic option for the treatment of intestinal inflammation associated with NEC.

Abstract
Matrix metalloproteinases (MMPs) are instrumental in the constant tissue remodeling in the ovary. An induction of MMP-19 mRNA in periovulatory follicles has been reported in mouse ovaries. However, little is known about MMP-19 expression during the follicular and luteal periods or about the ovarian regulation of MMP-19 mRNA expression. We examined the expression pattern of MMP-19 mRNA during various reproductive phases and the periovulatory regulation of MMP-19 mRNA in the rat ovary. In gonadotropin-primed, immature rat ovaries, levels of MMP-19 mRNA transiently increased during both follicular growth and ovulation. The MMP-19 mRNA was localized to the theca-interstitial layer of growing follicles and to the granulosa and theca-interstitial layers of periovulatory follicles. A similar expression pattern of MMP-19 mRNA in periovulatory follicles was observed in ovaries from naturally cycling adult rats. Accumulation of MMP-19 mRNA was detected in regressing corpus luteum. The regulation of MMP-19 mRNA expression during the periovulatory period was investigated via in vivo studies and through in vitro culture studies on follicular cells. The hCG-induction of MMP-19 mRNA was mimicked by treating granulosa cells, but not theca-interstitial cells, from preovulatory follicles with LH or activators of the protein kinase (PK) A or PKC pathways. Cycloheximide blocked the LH- or forskolin-induced MMP-19 mRNA expression, demonstrating the requirement for new protein synthesis. In contrast, blocking activation of the progesterone receptor or prostaglandin synthesis had no effect on the increase in MMP-19 mRNA expression. In conclusion, the induction of MMP-19 mRNA suggests an important role of this proteinase during follicular growth, ovulation, and luteal regression.

Abstract
OBJECTIVE To examine possible estrogen dependent endometrial expression of MMP-26 in vitro. DESIGN Experimental study. SETTING Department of Obstetrics and Gynecology of the Palacky University Medical School and University Hospital, Olomouc, Czech Republic, Department of Obstetrics and Gynecology, University Hospital, Lund, Sweden. METHODS We studied MMP-26 mRNA in 14 normal endometrial samples obtained from the proliferative phase of the menstrual cycle. Samples were cultured for five days either with estradiol alone or in combination with progesterone. Samples cultured with ethanol represented control groups. MMP-26 mRNA expression was examined in frozen samples using in situ hybridization. Immunohistochemistry was used to study the presence of estrogen and progesterone receptors in endometrial explants. RESULTS MMP-26 mRNA expression was highest in fresh (non cultured) samples. Signal intensity decreased during the first two days of culture and was negligable in the following days. Nuclear intensity for estrogen and progesterone receptor was high after five days of culture. CONCLUSION We did not find MMP-26 mRNA in vitro expression to be directly estrogen dependent.

Abstract
OBJECTIVE Matrix metalloproteinases (MMPs) are key players in the degradation of extracellular matrix and basement membranes, and are thus important in tumor invasion. Recently, MMP-26 (endometase), a novel matrilysin-type member of the MMP family, was cloned from an endometrial tumor. This study examines the expression of MMP-26 mRNA in hyperplastic, premalignant and malignant endometrial samples, and compares with normal endometrial tissue. METHODS Endometrial carcinoma samples (19) were histologically classified as well, intermediately and poorly differentiated. Samples with hyperplasia (n = 15) were classified as simple, complex, or complex with atypia. Normal endometrial specimens (n = 39) were classified according to an ideal 28-day menstrual cycle and subsequently grouped in the early, middle, and late parts of the cycle. All samples were analyzed using in situ hybridization and real time PCR. The probes used for in situ hybridization and real time PCR recognized non-overlapping sequences. MMP-26 protein was localized by immunohistochemistry. RESULTS MMP-26 mRNA was exclusively localized in the epithelial component of normal, hyperplastic, premalignant, as well as malignant samples. It was not found in the stroma of any tissue category. Quantifications with real time PCR as well as semi-quantifications of the in situ hybridization signal revealed maximal levels in normal tissue at midcycle and in endometrial hyperplasia both with and without atypia. The amount of MMP-26 mRNA decreased progressively with loss of histological differentiation in malignant samples. Immunostaining localized MMP-26 in epithelial glandular and luminal cells, in vessel walls, and in tumor cells. Since the pattern of MMP-26 expression mimicked that of ER-alpha, we searched the MMP-26 promoter region for a potential estrogen response element (ERE). A sequence at position -130 to -116 had high homology to the consensus sequence of an ERE. Based on these observations, we suggest that ER-alpha is involved in regulation of the MMP-26 gene. CONCLUSIONS MMP-26 mRNA is selectively localized in the epithelial compartment of normal, hyperplastic, and malignant endometrial tissue. Expression is high in normal and hyperplastic endometria, but is downregulated in the late part of the cycle and in malignant tumors. The expression pattern of MMP-26 mRNA mimics that of ER-alpha, and the promoter region of the MMP-26 gene has a potential ERE.

Abstract
We have previously reported that endometrial expression of matrix metalloproteinase (MMP)-26 mRNA comes to a maximum in the early secretory phase. Since tissue inhibitor of metalloproteinase (TIMP)-4 is a potent inhibitor of MMP-26, the objective of this study was to identify the pattern of TIMP-4 mRNA expression in the normal endometrial cycle. We also evaluated hyperplastic, pre-malignant (atypical hyperplasia) and malignant endometrial tissue. Endometrial TIMP-4 mRNA was localized in tissue sections using in situ hybridization, and quantified in tissue extracts using real-time PCR. Estrogen receptor alpha (ERalpha) was assayed in the same set of samples using immunohistochemistry. In situ hybridization demonstrated TIMP-4 mRNA in the stroma of both normal and pathological tissues. TIMP-4 mRNA increased in the proliferative phase to a maximum in the early secretory phase, and then decreased in the late part of the cycle. Expression was comparable in normal and hyperplastic (including atypical) endometrial samples, whereas lower levels were detected in malignant tumours. Since this general pattern of expression suggests estrogen dependence, we evaluated ERalpha in our samples. Tissue sections from the normal proliferative phase, hyperplasia and pre-malignant atypical hyperplasia tissue stained strongly for ERalpha, whereas weak staining was seen in the secretory phase and in malignant tumours. Thus, low level of ERalpha was accompanied by down-regulated TIMP-4 mRNA, supporting the hypothesis that ERalpha contributes to regulation of the TIMP-4 gene. In addition, we identified a putative estrogen response element (ERE) in the promoter region of the TIMP-4 gene at position -930 to -916. Similarities in the cyclic patterns of TIMP-4 mRNA and MMP-26 mRNA, together with the fact that TIMP-4 is a potent inhibitor of MMP-26, suggest a functional relationship, and furthermore a role in human implantation.

Abstract
Matrix metalloproteinase 19 (MMP-19) is able to process various proteins of the basement membrane. To investigate the impact of MMP-19 activity on endothelial cells in the context of tumor extracellular matrix (ECM), we treated Matrigel matrix with an active recombinant MMP-19 and analyzed its effect on capillary-like formation. Human microvascular endothelial cells (HMEC-1) could not form capillary-like formation on Matrigel treated with recombinant MMP-19. Analyzing the Matrigel proteins, we found that MMP-19 preferentially cleaved nidogen-1. The cleavage site of nidogen-1 was mapped to Thr867-Leu868. This cleavage separates the G3 globular domain containing the binding site for the gamma1 chain of laminin-1 and collagen IV and thus abolishes the capacity of nidogen-1 to cross-link ECM proteins. Anti-nidogen antibodies directed against the G3 domain of nidogen-1 inhibited the capillary-like structure formation to a similar extent as MMP-19. Since nidogen-1 is thought to stabilize microvessels, MMP-19 might be one of the enzymes that interferes with stabilization or maturation of nascent vasculature.

Abstract
Expression of matrilysin-2, matrix metalloproteinase (MMP)-26, has been implicated in the progression of several types of human cancer. Matrilysin-2 has been reported to be a physiological and pathological activator of pro-MMP-9. The aim of this study was to examine matrilysin-2 expression and determine whether it is correlated with progression of human esophageal squamous cell carcinoma (ESCC). Semi-quantitative reverse transcriptase-polymerase chain reaction, immunohistochemical analysis, zymography and an in vitro invasion assay were performed. Matrilysin-2 mRNA expression was undetectable or only faintly detected in non-tumor tissues, but its overexpression was detected in 24 of the 50 ESCC tissues. Matrilysin-2 overexpression was significantly correlated with depth of invasion, lymph node metastasis and an advance in pathological tumor node metastasis (pTNM) stage. Sections with immunostaining signals in >10% of carcinoma cells at the invasive front, which were observed in 46 of 100 cases, were judged to be positive for matrilysin-2 expression. Matrilysin-2 expression was significantly correlated with depth of invasion, lymph node and distant metastasis, advance in pTNM stage and recurrence. Expression of matrilysin-2 was significantly correlated with nuclear beta-catenin expression and MMP-9 expression. Patients with matrilysin-2-positive cancer had significantly shorter overall and disease-free survival periods than did those with matrilysin-2-negative cancer. Matrilysin-2 expression retained its significant predictive value for overall and disease-free survival in multivariate analysis. Moreover, patients with concomitant expression of matrilysin-2 and MMP-9 had the worst prognosis. Zymography revealed that matrilysin-2 expression was significantly correlated with expression of active MMP-9 in ESCC tissues. Matrilysin-2-transfected TE-1 ESCC cells showed active MMP-9 activity and were more invasive in vitro compared with mock-transfected TE-1 cells. The results of this study suggest that matrilysin-2, the expression of which is closely correlated with nuclear beta-catenin expression and active MMP-9 activity, plays a key role in the progression of ESCC.

Abstract
BACKGROUND Extramammary Paget's disease (EMPD) is a rare malignant neoplasm of apocrine gland bearing skin characterized by intraepidermal proliferation of adenocarcinoma cells. Tumor growth depends on the ability of tumor cells to migrate by proteolysis and on angiogenesis. The matrix metalloproteinase (MMP) enzymes have been implicated in both of these processes in other types of skin cancer. METHODS The expression of MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-13, and MMP-19 was analyzed by immuno- histochemistry and/or in situ hybridization in 27 EMPD and five mammary PD (MMPD) specimens. The distribution of laminin-5 (LN-5) and tenascin-C, two extracellular matrix proteins associated with tumor invasion, was studied by immunohistochemistry. RESULTS MMP-7 (matrilysin-1) and MMP-19 were the most frequently expressed MMPs in Paget's cells. Overexpression of MMP-2, MMP-9, or MMP-13, which is seen in many cancers, was not evident in EMPD. LN-5 and tenascin-C positivity did not correlate with the level of invasion. MMP-7, MMP-13, and MMP-19 were detected abundantly in MMPD, while MMP-9 was absent. CONCLUSIONS MMP expression did not generally associate with the level of invasion of EMPD. In three samples positive for MMP-7 and four samples positive for MMP-19, an underlying carcinoma was detected, suggesting the importance of these two MMPs as predictors of secondary EMPD or the putative origin of Paget's cells from the dermal adenocarcinoma cells of apocrine duct origin.

Abstract
Matrix metalloproteinase 19 (MMP-19) is a member of the MMP family of endopeptidases that, in contrast to most MMPs, is widely expressed in human tissues under normal quiescent conditions. MMP-19 has been found to be associated with ovulation and angiogenic processes and is deregulated in diverse pathological conditions such as rheumatoid arthritis and cancer. To gain further insights into the in vivo functions of this protease, we have generated mutant mice deficient in Mmp19. These mice are viable and fertile and do not display any obvious abnormalities. However, Mmp19-null mice develop a diet-induced obesity due to adipocyte hypertrophy and exhibit decreased susceptibility to skin tumors induced by chemical carcinogens. Based on these results, we suggest that this enzyme plays an in vivo role in some of the tissue remodeling events associated with adipogenesis, as well as in pathological processes such as tumor progression.

Abstract
There are several unorthodox features, which distinguish the non-redundant and unique novel matrix metalloproteinase-26 (MMP-26) (an enzyme that has recently evolved and does not exist in rodents but is present in humans) from other members of the MMP superfamily. This report describes our recent efforts to gain a better understanding of the mechanisms which restrict expression of MMP-26 to certain cell/tissue types. We examined transcriptional regulation of the human MMP-26 gene in normal and malignant cells. The AP-1 and Tcf-4 sites of the MMP-26 promoter appear most potent in regulating the expression of the MMP-26-luciferase chimera in HEK293 embryonic kidney and MCF7 breast carcinoma cells. Key regulators of the Wnt pathway (beta-catenin and lymphoid enhancer-binding factor/T-cell factor with which beta-catenin associates) enhanced the transcriptional activity of MMP-26 suggesting that the MMP-26 gene is a likely target of the Wnt pathway. Immunostaining, gene arrays and reverse-transcriptase polymerase chain reaction (RT-PCR) confirm the presence of MMP-26 in normal cells, including the apical epithelial conjunctiva cells of the human eye, as well as in malignant cells of epithelial origin. MMP-26 predominantly accumulates in its proenzyme form in the intracellular milieu of the transfected breast carcinoma MCF7 cells. This study brings us a step forward towards a better understanding of the unconventional role, regulation and functions of epithelial cell MMP-26 in physiological conditions and in neoplasms.

Abstract
Several matrix metalloproteinases (MMPs) have been implicated in intestinal inflammation, mucosal wound healing, and cancer progression. The purpose of this study was to examine the cellular location and putative function of MMP-19, MMP-26 (matrilysin-2), and MMP-28 (epilysin), in normal, inflammatory, and malignant conditions of the intestine. Peroperative tissue specimens from patients with ulcerative colitis (UC) (n = 16) and archival tissue samples of ischemic colitis (n = 9), Crohn's disease (n = 7), UC (n = 8), colon cancer (n = 20), and healthy intestine (n = 5) were examined using immunohistochemical analyses with polyclonal antibodies. Unlike many classical MMPs, MMP-19, MMP-26, and MMP-28 were all expressed in normal intestine. In inflammatory bowel disease (IBD), MMP- 19 was expressed in nonmigrating enterocytes and shedding epithelium. MMP-26 was detected in migrating enterocytes, unlike MMP-28. In colon carcinomas, MMP-19 and MMP-28 expression was downregulated in tumor epithelium. Staining for MMP-26 revealed a meshwork-like pattern between cancer islets, which was absent from most dedifferentiated areas. Our results suggest that MMP-19 is involved in epithelial proliferation and MMP-26 in enterocyte migration, while MMP-28 expression is not associated with inflammatory and destructive changes seen in IBD. In contrast to many previously characterized MMPs, MMP-19 and MMP-28 are downregulated during malignant transformation of the colon and may play a prominent role in tissue homeostasis.

Abstract
Most of the matrix metalloproteinases (MMP) are not expressed in normal intact skin but they are upregulated in inflamed or diseased skin. The recently cloned MMP-19 is one of the few MMP members that are also expressed in healthy epidermis. In this study, we found that MMP-19 is generally coexpressed with cytokeratin 14 that is confined to keratinocytes of the stratum basale. MMP-19 was also detected in hair follicles, sebaceous glands, and eccrine sweat glands. Its expression, however, changed in cutaneous diseases exhibiting increased alternations of epidermal proliferation, such as psoriasis, eczema, and tinea. In the affected area, MMP-19 was also found in suprabasal and spinous epidermal layers. We also studied the regulation of MMP-19 expression at the protein level, as well as by using a promoter assay. The constitutive expression of MMP-19 was upregulated with phorbol myristate acetate and downregulated with retinoic acid and dexamethasone. Tumor necrosis factor-alpha, interleukin (IL)-6, TGF-beta, IL-15, IL-8, and RANTES as well as the bacterial compounds lipopolysaccharide and lipoteichoic acid did not show any profound effect in HaCaT cells. In contrast, type IV and type I collagens upregulated MMP-19 significantly. The dysregulation of MMP-19 expression in epidermis suggests its possible involvement in the perpetuation of cutaneous infections and proliferative disorders such as psoriasis.

Abstract
Tissue inhibitors of metalloproteinases (TIMPs) are the endogenous modulators of the zinc-dependent mammalian matrix metalloproteinases (MMPs) and their close associates, proteinases of the ADAM (a disintegrin and metalloproteinase) and ADAM with thrombospondin repeats families. There are four variants of TIMPs, and each has its defined set of metalloproteinase (MP) targets. TIMP-1, in particular, is inactive against several of the membrane-type MMPs (MT-MMPs), MMP-19, and the ADAM proteinase TACE (tumor necrosis factor-alpha-converting enzyme, ADAM-17). The molecular basis for such inactivity is unknown. Previously, we showed that TIMP-1 could be transformed into an active inhibitor against MT1-MMP by the replacement of threonine 98 residue with leucine (T98L). Here, we reveal that the T98L mutation has in fact transformed TIMP-1 into a versatile inhibitor against an array of MPs otherwise insensitive to wild-type TIMP-1; examples include TACE, MMP-19, and MT5-MMP. Using T98L as the scaffold, we created a TIMP-1 variant that is fully active against TACE. The binding affinity of the mutant (V4S/TIMP-3-AB-loop/V69L/T98L) (K (app)(i) 0.14 nm) surpassed that of TIMP-3 (K (app)(i) 0.22 nm), the only natural TIMP inhibitor of the enzyme. The requirement for leucine is absolute for the transformation in inhibitory pattern. On the other hand, the mutation has minimal impact on the MPs already well inhibited by wild-type TIMP-1, such as gelatinase-A and stromelysin-1. Not only have we unlocked the molecular basis for the inactivity of TIMP-1 against several of the MPs, but also our findings fundamentally modify the current beliefs on the molecular mechanism of TIMP-MP recognition and selectivity.

Abstract
Local disruption of the integrity of both the myoepithelial cell layer and the basement membrane is an indispensable prerequisite for the initiation of invasion and the conversion of human breast ductal carcinoma in situ (DCIS) to infiltrating ductal carcinoma (IDC). We previously reported that human endometase/matrilysin-2/matrix metalloproteinase (MMP) 26-mediated pro-gelatinase B (MMP-9) activation promoted invasion of human prostate carcinoma cells by dissolving basement membrane proteins (Y. G. Zhao et al., J. Biol. Chem., 278: 15056-15064, 2003). Here we report that tissue inhibitor of metalloproteinases (TIMP)-2 and TIMP-4 are potent inhibitors of MMP-26, with apparent K(i) values of 1.6 and 0.62 nM, respectively. TIMP-2 and TIMP-4 also inhibited the activation of pro-MMP-9 by MMP-26 in vitro. The expression levels of MMP-26, MMP-9, TIMP-2, and TIMP-4 proteins in DCIS were significantly higher than those in IDC, atypical intraductal hyperplasia, and normal breast epithelia adjacent to DCIS and IDC by immunohistochemistry and integrated morphometry analysis. Double immunofluorescence labeling and confocal laser scanning microscopy revealed that MMP-26 was colocalized with MMP-9, TIMP-2, and TIMP-4 in DCIS cells. Higher levels of MMP-26 mRNA were also detected in DCIS cells by in situ hybridization.

Abstract
Squamous cell carcinoma (SCC) of the oral cavity is a highly invasive tumour of stratified squamous epithelium that spreads through degradation of the basement membrane (BM) and extracellular matrix (ECM). There are currently no reliable tissue or serum markers to predict whether the tumour has metastasized at the time of diagnosis. Verrucous carcinoma (VC) of the oral cavity is a rare low-grade variant of oral SCC that penetrates into the subepithelial connective tissue. Many matrix metalloproteinases (MMPs), such as MMP-1, -2, -7, -9, -13, and -14, as well as integrin receptors have been implicated in cancer invasion. Integrin alphavbeta6 is induced in SCC and appears to be involved in up-regulation of MMP-9 expression by oral keratinocytes and promotion of their migration. The aim of this study was to investigate whether the pattern of MMP expression or that of alphavbeta6 integrin contributes to the differences in the biological behaviour of oral SCC and VC. The results show that the less aggressive nature of oral VC may be connected to its MMP expression profile. Typically, VCs were devoid of epithelial MMP-3, -7, -9, -12 and -13 expression, compared with SCCs. MMP-19 was expressed by epithelial keratinocytes in hyperproliferative areas of verrucous hyperplasia, VC, and SCC, but was absent in the invasive cancer cell nests of SCC. MMP-26 was expressed by hyperproliferative keratinocytes in VC as well as by invasive cancer cells in SCCs. MMP-10 was expressed widely in the epithelium of all SCC specimens. alphavbeta6 integrin expression was also detected in some cases of epithelial hyperplasia but was significantly more abundant in cancers at the invasive front. The absence of MMP-7, -9 and -12 from epithelial cells may serve as a good prognostic marker of non-invasive oral carcinoma. Blocking the activity of invasion-specific MMPs or alphavbeta6 integrin might offer novel therapeutic modalities in early-stage oral carcinoma.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) contribute in multiple ways to all stages of tumor development, and a number of DNA polymorphisms in the MMP genes are associated with an increased risk of cancer. We previously identified the MMP-21 gene 572C/T polymorphism leading to Ala191Val substitution within the enzyme's catalytic domain. We performed a case-control study to test association between this polymorphism and the risk of breast cancer. PATIENTS AND METHODS 572C/T polymorphism was analyzed by RFLP method in 396 unrelated Russian females: 76 breast cancer patients and 320 disease-free blood donors. RESULTS The frequencies of C/C, T/C and T/T genotypes in patients (69.7%, 25.0% and 5.3%) did not differ significantly from those in controls (61.9%, 34.7% and 3.4%); the polymorphism was not associated with the increased tumor size and the presence of metastases. CONCLUSION The MMP-21 gene 572C/T polymorphism has no significant effect on the development and progression of breast cancer.

Abstract
Human matrix metalloproteinase-26 (MMP-26/endometase/matrilysin-2) is a newly identified MMP and its structure has not been reported. The enzyme active site S1' pocket in MMPs is a well defined substrate P1' amino acid residue-binding site with variable depth. To explore MMP-26 active site structure-activity, a series of new potent mercaptosulfide MMP inhibitors (MMPIs) with Leu or homophenylalanine (Homophe) side chains at the P1' site were selected. The Homephe side chain is designed to probe deep S1' pocket MMPs. These inhibitors were tested against MMP-26 and several MMPs with known x-ray crystal structures to distinguish shallow, intermediate, and deep S1' pocket characteristics. MMP-26 has an inhibition profile most similar to those of MMPs with intermediate S1' pockets. Investigations with hydroxamate MMPIs, including those designed for deep pocket MMPs, also indicated the presence of an intermediate pocket. Protein sequence analysis and homology modeling further verified that MMP-26 has an intermediate S1' pocket formed by Leu-204, His-208, and Tyr-230. Moreover, residue 233 may influence the depth of an MMP S1' pocket. The residue at the equivalent position of MMP-26 residue 233 is hydrophilic in intermediate-pocket MMPs (e.g. MMP-2, -8, and -9) and hydrophobic in deep-pocket MMPs (e.g. MMP-3, -12, and -14). MMP-26 contains a His-233 that renders the S1' pocket to an intermediate size. This study suggests that MMPIs, protein sequence analyses, and molecular modeling are useful tools to understand structure-activity relationships and provides new insight for rational inhibitor design that may distinguish MMPs with deep versus intermediate S1' pockets.

Abstract
Human matrix metalloproteinase-21 (MMP-21), the newest member of the MMP gene family, has been suggested to play an important role in embryogenesis and tumor progression and to be a target of the Wnt, Pax, and Notch signaling pathways. Here we report detection of MMP-21 by RT-PCR in mouse embryos aged 10.5, 12.5, 13.5, and 16.5 days, as well as in various adult murine organs. In both humans and mice, MMP-21 protein was detected in the epithelial cells of developing kidney, intestine, neuroectoderm, and skin but not in normal adult skin using immunohistochemistry with two unrelated antibodies. However, it was present in invasive cancer cells of aggressive subtypes of basal and squamous cell carcinomas, although it was not expressed in skin disorders characterized by mere keratinocyte hyperproliferation. Of several cytokines tested, transforming growth factor-beta1 induced MMP-21 in vitro in HaCaTs and keratinocytes as judged by real-time quantitative TaqMan PCR. Although suprabasal differentiating keratinocytes expressed MMP-21 in developing skin in vivo, MMP-21-positive keratinocytes were detected by immunohistochemistry in both low and high calcium cultures. MMP-21 expression was not up-regulated by ras transformation in HaCaT cell lines (HaCaT, A5, II-4, and RT3); in skin and colon cancers, its expression did not associate with apoptosis, beta-catenin transactivation, or epithelial MMPs-9 and -10. However, MMP-21 protein was found in the same regions as MMP-7 but not in the same cells. Our results suggest that during development, MMP-21 expression is temporally and spatially tightly controlled. Unlike many classical MMPs, it is present in various normal adult tissues. Among epithelial MMPs, MMP-21 has a unique expression pattern in cancer.

Abstract
Here, we have examined the expression of matrix metalloproteinase-19 (MMP-19) in human cutaneous wounds and by human skin fibroblasts in culture. Expression of MMP-19 was detected by immunohistochemistry in fibroblasts, capillary endothelial cells, and macrophages in the dermal layer of large granulating wounds, as well as in chronic venous and decubitus ulcers. MMP-19 mRNA expression and pro-MMP-19 production by dermal fibroblasts in culture was potently enhanced by tumor necrosis factor-alpha (TNF-alpha). Induction of MMP-19 expression by TNF-alpha was prevented partially by blocking the activation of extracellular signal-regulated kinase (ERK)-1/2 by PD98059 and p38 activity by SB203580. Activation of ERK1/2 by adenovirus-mediated delivery of constitutively active MAPK/ERK kinase 1 resulted in the induction of MMP-19 expression. Activation of p38 alone by adenovirally delivered constitutively active MAPK kinase 3b (MKK3b) and MKK6b also enhanced MMP-19 production, and the most potent induction of MMP-19 expression was noted when ERK1/2 was activated in combination with p38. Activation of c-Jun N-terminal kinase (NK). Abundant pro-MMP-19 production by fibroblasts was associated with proteolytic processing of secreted pro-MMP-19. These results suggest a role of MMP-19 in cutaneous wound repair and identify three distinct signaling pathways, which coordinately mediate induction of MMP-19 expression in fibroblasts: mitogen-activated ERK1/2 pathway and stress-activated JNK and p38 pathways, of which control proteolytic activity of dermal fibroblasts.

Abstract
Unlike most other matrix metalloproteinases (MMPs) MMP-19 is expressed in undifferentiated basal keratinocytes of healthy human skin. The human keratinocyte cell line HaCaT, which like basal keratinocytes constitutively expresses MMP-19, down-regulated the expression of MMP-19 at high calcium concentrations. Calcium-regulation occurred through E-cadherin mediated cell-cell contacts because neutralizing anti-E-cadherin antibodies restored MMP-19 expression in high calcium. Overexpression of MMP-19 in HaCaT cells (HaCaT-WT) increased cellular proliferation, as well as migration and adhesion on type I collagen. This was due to proteolysis of the insulin-like growth factor (IGF) binding protein-3 by MMP-19, which augmented signaling through the IGF-I receptor, as evidenced by its increased autophosphorylation. Conversely, these effects were not observed in cells transfected with MMP-2 or a catalytically inactive MMP-19 mutant. As further proof that increased IGF-signaling promoted adhesion and migration in HaCaT-WT cells, we reproduced these effects by treating parental HaCaT with IGF-I. We observed dephosphorylation of the focal adhesion kinase in HaCaT-WT as well as IGF-I-treated HaCaT cells, suggesting that inactivating focal adhesion kinase is a mechanism by which IGF-I enhances adhesion. Furthermore, IGF-I-triggered motility on type I collagen was mediated by MMP activity, which, however, was distinct from MMP-19. Considering the coexpression of IGFBP-3 and MMP-19 in the skin, we conclude that MMP-19 is a likely candidate to be the major IGFBP-3 degrading MMP in the quiescent epidermis. This activity might have widespread consequences for the behavior of epidermal keratinocytes.

Abstract
Epilysin (MMP-28) is a recently identified member of the matrix metalloproteinase (MMP) family. To explore the expression of epilysin in vivo and to gain insight into its biological functions, we have cloned the mouse epilysin cDNA and determined its expression. The amino acid sequence of the mouse protein is 85% identical with the human sequence and contains conserved features such as an RKKR furin-activation sequence following the prodomain. Unexpectedly, we found two alternatively spliced forms of the epilysin mRNA lacking 30 and 72 nt at the beginning of the seventh exon coding for part of the haemopexin domain. Expression of recombinant epilysin in HT-1080 fibrosarcoma cells indicated that epilysin was secreted as a major 48 kDa form and a minor 58 kDa form. Expression of the 58 kDa form was increased by a synthetic furin inhibitor at the expense of the 48 kDa form, suggesting that furin cleaves and activates epilysin. Epilysin mRNA was detected in a number of mouse tissues, with the highest expression in the lung, placenta, heart and uterus, and lower levels in the testis and gastrointestinal tract. The wide expression of epilysin in intact, healthy tissues suggests that this MMP functions in physiological tissue homoeostasis and turnover.

Abstract
Keratinocyte hyperproliferation, inflammatory infiltrates, neoangiogenesis and alterations in cytokine levels are hallmarks of psoriatic skin. Matrix metalloproteinases (MMPs) have been associated with the remodeling of the extracellular matrix during inflammation, neovascularization, and malignant transformation. We have previously shown that particularly MMP-12 is abundantly expressed by macrophages and MMP-9 in macrophages and neutrophils of psoriatic lesions. In this work the expression of two novel metalloproteinases, MMP-19 and MMP-28, was investigated in psoriatic lesional and non-lesional skin. MMP-19 protein was detected by immunohistochemistry in 28/29 samples in keratinocytes in the same regions as Ki67 (marker of proliferating keratinocytes) and p63 (marker of keratinocyte stem cells). Immunosignaling was also seen in endothelial cells and fibroblasts. Furthermore, MMP-19 mRNA was upregulated in psoriatic keratinocytes and skin as assessed by quantitative real-time polymerase chain reaction. In lichen planus and lichenoid chronic dermatitis, MMP-19 staining was found in keratinocytes in areas where the basement membrane was abnormal. MMP-28 was not detected in psoriatic or non-lesional skin. Our results suggest that keratinocytes as well as the previously reported cell types (smooth muscle, endothelial and macrophages) can express MMP-19 in psoriasis and lichen planus. Upregulation of MMP-19 in keratinocytes may be influenced by changes in the architecture of the basement membrane zone.
