Abstract
Among individuals with localized (Stage I-II) melanoma, stratifying patients by a number of phenotypic variables (e.g., depth of invasion, ulceration) yields a wide range of 10-year melanoma-specific survival rates. With the possible exception of Ki-67, no molecular assessment is routinely used. However, there have been a tremendous number of studies assessing protein expression by immunohistochemistry toward the goal of better prediction of recurrence. In a previous systematic review, which required publication of multivariable prognostic models as a strict inclusion criterion, we identified 37 manuscripts that collectively reported on 62 proteins. Data for 324 proteins extracted from 418 manuscripts did not meet our inclusion criteria for that study, but are revisited here, emphasizing trends of protein expression across either melanocytic lesion progression or gradations of tumor thickness. These identified 101 additional proteins that stratify melanoma, organized according to the Hanahan and Weinberg functional capabilities of cancer.

Abstract
Tumor invasion and metastasis of malignant melanoma have been shown to require proteolytic degradation of the extracellular environment achieved primarily by enzymes of the matrix metalloproteinases (MMP) family. We have earlier shown that increased enzyme activity is localized at the border of tumor cells and the adjacent peritumoral connective tissue, emphasizing the importance of tumor-stroma interactions in the regulation of MMP activity. To confirm the role of stroma-derived MMP-13 in the invasion process, we investigated the invasiveness of melanoma cells upon intradermal injection in mice with complete inactivation of MMP-13. Tumor growth was significantly impaired in mmp-13(-/-) mice and most significant at early time points as compared with wild-type littermates. Moreover, metastasis to various organs was reduced to 17.6 vs 30% in lungs, 2.9 vs 30% in the liver. Strikingly, ablation of MMP-13 completely abrogated formation of metastasis in the heart (0 vs 40%). Notably, decreased tumor growth in mmp-13(-/-) mice was associated with reduced blood vessel density. In addition, decreased blood vessel permeability in the tumors was measured by magnetic resonance imaging of tumor-bearing animals. These data suggest an important role of MMP-13 in tumor growth and an unexpected role in organ-specific metastasis of melanoma cells.

Abstract
BACKGROUND Squamous cell carcinoma of the head and neck (HNSCC) is a common cancer type. The ability for curative treatment with surgery and radiotherapy (RT) is usually highly dependent on tumor stage at the time of diagnosis. METHODS The purpose of this study was to determine whether the expression of a cancer-specific proteinase, collagenase-3 (matrix metalloproteinase-13 [MMP-13]), is associated with survival parameters in patients with HNSCC. We studied MMP-13 expression in tumors of 81 patients with stage I-IV HNSCC treated with surgery alone or in combination with radiotherapy. RESULTS We found a subgroup of patients with high MMP-13 expression level in their tumors (>/=90% MMP-13-positive tumor cells) associated with unfavorable prognosis (median overall survival [OS], 11.8 vs 19.6 months, p = .032). In addition, the median disease-specific survival (DSS) time was markedly reduced in this subgroup (13.8 months vs 40.7 months, p = .062). When the subgroup of patients treated with a curative intent was studied, the same association was found in OS (13.8 vs 24.6 months, p = .023) and DSS (p = .004). In addition, there was a trend for association between >/=90% MMP-13 positivity and a recurrent tumor (p = .078) in curatively treated patients. CONCLUSIONS The short survival time associated with high MMP-13 expression levels could not be predicted by tumor size or local lymph node invasion. These results show that a high MMP-13 expression level is associated with aggressiveness of HNSCC and may have prognostic value in patient evaluation.

Abstract
Squamous cell carcinoma (SCC) cells of the head and neck specifically express collagenase-3 (matrix metalloproteinase-13 (MMP-13)), the expression of which correlates with their invasion capacity. Transforming growth factor-beta (TGF-beta) enhances MMP-13 and collagenase-1 (MMP-1) expression and invasion of SCC cells via p38 mitogen-activated protein kinase. Here, we have examined the role of Smad signaling in regulating MMP-13 expression and in invasion of head and neck SCC cells. Treatment with TGF-beta resulted in activation of Smad2 and Smad3 in SCC cells, but had no effect on their proliferation or viability. Basal activation of Smad3 and p38 was noted in SCC cells without exogenous TGF-beta stimulation, and adenoviral delivery of Smad7 and dominant-negative Smad3 inhibited p38 activation in these cells. Adenoviral overexpression of Smad3 augmented the upregulatory effect of TGF-beta on MMP-13 expression by SCC cells. Disruption of Smad signaling by adenoviral expression of kinase-defective TGF-beta type I receptor (activin-receptor-like kinase-5), Smad7, and dominant-negative Smad3 potently suppressed the basal and TGF-beta-induced expression of MMP-13 and MMP-1 in SCC cells, and inhibited their basal and TGF-beta-induced invasion through Matrigel and type I collagen. Adenoviral overexpression of Smad7 in cutaneous and oral SCC cells significantly inhibited their implantation in skin of SCID mice and growth of xenografts in vivo, as compared to LacZ adenovirus-transduced control cells. Together, these results show that Smad signaling plays an important role in promoting the invasive phenotype of human head and neck SCC cells by upregulating their collagenase expression.

Abstract
BACKGROUND Matrix metalloproteases (MMPs), enzymes with the ability to degrade the extracellular matrix, play an important role in tissue invasion by cutaneous malignant melanoma (CMM). One specific MMP, collagenase-3 (MMP-13), is thought to have a key function in the activation of MMP. AIMS To evaluate the expression of MMP-13 in CMM and assess its possible relationship to clinical and pathological parameters. METHODS MMP-13 expression was analyzed in 51 paraffin-embedded tumor samples from patients with invasive CMM, ten samples from in situ melanomas, and in eight samples from benign lesions (three dermal melanocytic nevi, three compound melanocytic nevi and two atypical melanocytic nevi) using immunohistochemical techniques. The median follow-up period in patients with invasive CMM was 50 months. RESULTS Benign lesions were consistently negative for MMP-13, whereas three of the ten in situ melanomas (30%) and 23 of the 51 invasive CMMs (45%) showed positive immunostaining for MMP-13. The percentage of MMP-13-positive tumors correlated significantly and positively with the mitotic index (p=0.002) in invasive CMM. However, our results did not show any significant association between tumoral MMP-13 expression and relapse-free survival in patients with invasive CMM. CONCLUSIONS MMP-13 appears to be a factor associated with tumor aggressiveness in CMM. It seems to eliminate an important barrier not only against tumoral invasion but also against proliferation.

Abstract
Reactive oxygen species have been shown to play an important role in the regulation of distinct signaling cascades, many of which act upon the production of matrix metalloproteinases (MMP). Using a series of redox-engineered cell lines we have previously demonstrated that MMP-1 expression is sensitive to the alterations in the steady state production of H2O2 (Ranganathan, A. C., Nelson, K. K., Rodriguez, A. M., Kim, K. H., Tower, G. B., Rutter, J. L., Brinckerhoff, C. E., Epstein, C. J., Huang, T. T., Jeffrey, J. J., and Melendez, J. A. (2001) J. Biol. Chem. 276, 14264-14270). In the present study, we investigate the molecular mechanisms involved in the H2O2-mediated induction of MMP-1. Mutational analysis of an MMP-1 promoter indicates that both the single nucleotide polymorphism creating an Ets binding site at -1607 and a proximal AP-1 site at -1602 are required for maximal H2O2-dependent transcription. The redox-sensitive MMP-1 protein expression requires activation of both ERK1/2 and JNK pathways. Importantly, JNK signaling is largely responsible for the H2O2 sensitivity of the MMP-1 promoter, whereas ERK1/2 contributes to both its basal and H2O2 dependence. H2O2 control of Ets-1 expression was ERK1/2-dependent whereas that of c-Jun requires both ERK1/2 and JNK signaling. Chromatin immunoprecipitation assays indicate that binding of the histone acetyltransferase, p300, and the transcription factors Ets-1 and c-Jun to the MMP-1 promoter is redox sensitive. The redox sensitivity of MMP-1 expression is also associated with an increase in the abundance of oxidatively inactivated protein-tyrosine phosphatases. Targeted cytosolic or mitochondrial scavenging of H2O2 prevented all of the aforementioned signals. These studies provide substantial insight into the mechanisms underlying the redox-dependent control of MMP-1 and may lead to the development of novel targeted antioxidant-based inhibitory therapies for controlling MMP-1 expression during degenerative disease processes.

Abstract
Three mammalian collagenases (MMP-1, MMP-8, and MMP-13) belong to family of matrix metalloproteinases and are the principal secreted endopeptidases capable of cleaving collagenous extracellular matrix. In addition to fibrillar collagens, collagenases can cleave several other matrix and non-matrix proteins including growth factors, and this way regulate cell growth and survival. Collagenases are important proteolytic tools for extracellular matrix remodeling during organ development and tissue regeneration, but they also apparently play important roles in many pathological situations and tumor progression and metastasis. Because of their potentially destructive characteristics the expression and activity of collagenases are strictly controlled. Synthesis of collagenases is regulated by extracellular signals via cellular signal transduction pathways at transcriptional and post-transcriptional level. Collagenases are synthesized as inactive pro-forms, and once activated, their activity is inhibited by specific tissue inhibitors of metalloproteinases, TIMPs, as well as by non-specific proteinase inhibitors. In this review we discuss the current view on the role of collagenases in tumor growth, invasion, and metastasis, as a basis for their feasibility in diagnosis and prognostication, as well as therapeutic targets in cancer patients.

Abstract
PURPOSE Matrix metalloproteinases (MMP) are proteolytic enzymes that play an important role in various aspects of cancer progression. In the present work, we have studied the prognostic significance of serum levels of gelatinase B (MMP-9), collagenase-1 (MMP-1), and collagenase-3 (MMP-13) in patients with advanced melanoma. EXPERIMENTAL DESIGN Total pretreatment serum levels of MMP-9 in 71 patients and MMP-1 and MMP-13 in 48 patients were determined by an assay system based on ELISA. Total MMP levels were also assessed in eight healthy controls. The active and latent forms of MMPs were defined by using Western blot analysis and gelatin zymography. RESULTS Patients with high serum levels of MMP-9 (> or = 376.6 ng/mL; n = 19) had significantly poorer overall survival (OS) than patients with lower serum MMP-9 levels (n = 52; median OS, 29.1 versus 45.2 months; P = 0.033). High MMP-9 levels were also associated with visceral or bone metastasis (P = 0.027), elevated serum alkaline phosphatase level (P = 0.0009), and presence of liver metastases (P = 0.032). Serum levels of MMP-1 and MMP-13 did not correlate with OS. MMP-1 and MMP-9 were found mainly in latent forms in serum, whereas the majority of MMP-13 in serum was active (48 kDa) form. MMP-13 was found more often in active form in patients (mean, 99% of the total MMP-13 level) than in controls (mean, 84% of the total MMP-13 level; P < 0.0001). After initiating the therapy, patients with elevated levels of MMP-1 (> or = 29.8 ng/mL, n = 10) progressed more rapidly than patients with lower levels (median, 1.9 versus 3.5 months; P = 0.023). Serum levels of MMP-9 and MMP-13 did not correlate with the time to progression (TTP). In multivariate analysis with age and gender, MMP-9 or MMP-1 turned out to be independent prognostic factors for OS [P = 0.039; hazard ratio (HR), 1.8; 95% confidence interval (95% CI), 1.03-3.3] or TTP (P = 0.023; HR, 2.7; 95% CI, 1.15-6.4), respectively. CONCLUSIONS Our findings provide evidence that MMP-1, MMP-9, and MMP-13 play important roles at different phases of metastatic melanoma spread and that serum MMP-9, in particular, could have clinical value in identifying patients at high risk for melanoma progression.

Abstract
Previous work has shown that endothelial cell (EC)-derived matrix metalloproteinases (MMPs) regulate regression of capillary tubes in vitro in a plasmin- and MMP-1 dependent manner. Here we report that a number of serine proteases can activate MMP-1 and cause capillary tube regression; namely plasma kallikrein, trypsin, neutrophil elastase, cathepsin G, tryptase and chymase. Plasma prekallikrein failed to induce regression without coactivators such as high molecular weight kininogen (HMWK) or coagulation Factor XII. The addition of trypsin, the neutrophil serine proteases (neutrophil elastase and cathepsin G) and the mast cell serine proteases (tryptase and chymase) each caused MMP-1 activation and collagen type I proteolysis, capillary tubular network collapse, regression and EC apoptosis. Capillary tube collapse is accompanied by collagen gel contraction, which is strongly related to the wound contraction that occurs during regression of granulation tissue in vivo. We also report that proMMP-10 protein expression is markedly induced in ECs undergoing capillary tube morphogenesis. Addition of each of the serine proteases described above led to activation of proMMP-10, which also correlated with MMP-1 activation and capillary tube regression. Treatment of ECs with MMP-1 or MMP-10 siRNA markedly delayed capillary tube regression, whereas gelatinase A (MMP-2), gelatinase B (MMP-9) and stromelysin-1 (MMP-3) siRNA-treated cells behaved in a similar manner to controls and regressed normally. Increased expression of MMP-1 or MMP-10 in ECs using recombinant adenoviral delivery markedly accelerated serine protease-induced capillary tube regression. ECs expressing increased levels of MMP-10 activated MMP-1 to a greater degree than control ECs. Thus, MMP-10-induced activation of MMP-1 correlated with tube regression and gel contraction. In summary, our work demonstrates that MMP-1 zymogen activation is mediated by multiple serine proteases and MMP-10, and that these events are central to EC-mediated collagen degradation and capillary tube regression in 3D collagen matrices.

Abstract
Robust expression of alphav integrin and matrix metalloproteinase 1 (MMP1) plays an important role in cancer metastasis and wound healing. A patient with an abnormal scar that appeared stretched and thinned out was found to have fibroblasts that overexpressed alphav integrin; therefore, a relationship between alphav integrin expression and MMP1 production was sought. A yeast 2 hybrid screen revealed alphav integrin interacts with jun activation binding domain-1 (JAB1). Mesenchymal-derived cells were transfected with the alphav integrin gene and incorporated into collagen lattices. Transfected cells maximally contracted collagen lattices beginning on day 5, whereas control transfected cells did not contract lattices. Late-phase collagen lattice contraction was inhibited by a pan-MMP inhibitor, BB4. Overexpression of alphav correlated with enhanced MMP1 transcription, as determined by a luciferase assay (P < or = 0.05). Diminution of JAB1 with JAB1 antisense abolished alphav integrin up-regulation of MMP1. We conclude alphav integrin signals through JAB1 to prolong MMP1 production and that this signaling pathway in fibroblasts may lead to abnormal scarring.

Abstract
The lack of efficacy of available therapies for the treatment of malignant melanoma has emphasized the need to develop novel therapeutic strategies to prevent melanoma growth. We have tested whether the anti-HMW-MAA mAb 225.28S is able to inhibit human melanoma tumor growth in SCID mice because in vitro data suggested that this antigen plays a role in spreading, migration and invasion of melanoma cells. Tumors were established by subcutaneous injection of the human melanoma cell line 518A2 into SCID mice. When tumors reached a size of 5 mm, the mAb 225.28S was administered intravenously 4 times in 3 day intervals at 100 microg/injection. Within 14 days after the first administration of the mAb 225.28S, tumor growth was reduced by 52% as compared to control mice. Three hundred and seven genes of >20,000 genes contained on the GeneChip were changed in their expression level at least 2-fold after administration of the mAb 225.28S. The encoded proteins were mostly components or modifiers of the extracellular matrix, tumor suppressors, and melanogenesis associated proteins. Surprisingly, the administration of the control mAb that did not lead to a significant tumor growth inhibition in vivo resulted in the modulation of two-thirds of these genes. This is the first report of suppression of human melanoma tumor growth in SCID mice by the mAb 225.28S. Our results suggest that anti-HMW-MAA mAbs may represent useful reagents to apply passive immunotherapy to patients with malignant melanoma.

Abstract
Reactive oxygen species (ROS) are constantly generated in aerobic organisms during normal metabolism and in response to both internal and external stimuli. Imbalances in the production and removal of ROS have been hypothesized to play a causative role in numerous disease pathologies such as cancer, ischemia/reperfusion injury, and degenerative diseases such as photoaging, atherosclerosis, arthritis, and neurodegeneration. A feature often associated with these diseases is a malfunctioning of the connective tissue remodeling process due to increased activity of extracellular matrix-degrading metalloproteinases (MMPs). This review summarizes the evidence that implicates ROS as key regulators of MMP production and the importance of these interactions in disease pathologies.

Abstract
Squamous cell carcinomas (SCCs) of the head and neck are characterized by a high tendency for local invasion and metastasis to lymph nodes. Collagenase-3 (MMP-13) is specifically expressed by tumor cells in SCCs of the head and neck and its expression correlates with their invasion capacity. To specifically examine the role of MMP-13 in the growth and invasion of SCC, we constructed a hammerhead ribozyme targeted against human MMP-13 mRNA. The anti-MMP-13 ribozyme effectively cleaved MMP-13 transcripts in vitro. Adenoviral delivery of the anti-MMP-13 ribozyme to cutaneous metastatic SCC cells in culture resulted in potent and specific inhibition of the production of proMMP-13 and markedly suppressed invasion of SCC cells through Matrigel. In addition, adenoviral delivery of anti-MMP-13 ribozyme promoted apoptosis in SCC cells within 72 h. Intratumoral injection of anti-MMP-13 ribozyme coding adenovirus into human SCC xenografts established in SCID mice potently suppressed tumor growth, inhibited MMP-13 expression and gelatinolytic activity and reduced the number of proliferating cells within the tumors. These results provide evidence for an important role for MMP-13 in SCC growth and invasion and identify MMP-13 as a promising target for ribozyme-based therapy of SCC in vivo.

Abstract
We have studied the effect of a newly identified tumor suppressor tissue inhibitor of metalloproteinases- 3 (TIMP-3) on the growth of human melanoma and squamous-cell carcinoma (SCC). Adenoviral delivery of the TIMP-3 gene to human melanoma (A2058) and SCC (UT-SCC-7) cells ex vivo inhibited tumorigenesis after subcutaneous (s.c.) injection of the infected cells into SCID/SCID mice. Three daily consecutive intratumoral injections of 1.4x10(9) plaque-forming units (pfu) of TIMP-3 adenovirus (RAdTIMP-3) inhibited the growth of preestablished melanoma and SCC xenografts in SCID/SCID mice, whereas growth of control virus-injected tumors was not affected. The antitumor effect of RAdTIMP-3 was obtained with in vivo adenoviral transduction efficiency of 8-10%, and it was more potent than that of adenovirally delivered p53. Adenovirusmediated expression of TIMP-3 potently reduced gelatinolytic activity, increased the number of apoptotic cells, and inhibited vascularization of melanomas. Escalation of the adenoviral dose to three rounds of three daily consecutive injections with 1.4x10(9) pfu of RAdTIMP-3 every 6 days entirely inhibited growth of injected melanomas for 32 days. Mixing RAdTIMP-3-infected A2058 cells with uninfected cells in 1:1 ratio in culture resulted in death of all cells in 96 hours. Adenovirally delivered TIMP-3 was also expressed by A2058 cells in soluble form into the culture medium, where it exerted a cytotoxic effect on uninfected A2058 cell cultures after relocating to the cell layer. These results identify TIMP-3 as a novel type of secreted tumor suppressor, which has antiinvasive, antiangiogenic, and proapoptotic effects in vivo, and which displays a potent bystander effect validating further exploration of its applicability in human cancer gene therapy.

Abstract
Degradation of extracellular matrix is crucial for malignant tumour growth, invasion, metastasis and angiogenesis. Matrix metalloproteinases (MMPs) are a family of zinc-dependent neutral endopeptidases collectively capable of degrading essentially all matrix components. Elevated levels of distinct MMPs can be detected in tumour tissue or serum of patients with advanced cancer and their role as prognostic indicators in cancer is studied. In addition, therapeutic intervention of tumour growth and invasion based on inhibition of MMP activity is under intensive investigation and several MMP inhibitors are in clinical trials in cancer. In this review, we discuss the current view on the feasibility of MMPs as prognostic markers and as targets for therapeutic intervention in cancer.

Abstract
Squamous cell carcinomas (SCCs) of the head and neck are characterized by high tendency to invade locally and metastasize to lymph nodes. SCC cells express several matrix metalloproteinases (MMPs) and they often harbor mutations in p53 tumor suppressor gene. Collagenase-3 (MMP-13) is specifically expressed by tumor cells of SCCs and it apparently plays an important role in their invasion and metastasis. We used adenoviral gene delivery to examine the effect of wild-type p53 on MMP-13 expression in four head and neck SCC cell lines with mutated p53. Adenoviral delivery of p53 resulted in potent inhibition in production of proMMP-13 (by 71 to 92%) and collagenase-1 (MMP-1) (by 27 to 93%) by all cell lines in 24 h, whereas production of gelatinase-A (MMP-2) and gelatinase-B (MMP-9) was not altered. Adenoviral expression of p53 also suppressed invasion of SCC cells through Matrigel by 35%. Expression of cyclin-dependent kinase inhibitor p21(Waf1/Cip1) was induced 24 h after p53 gene delivery in all SCC cell lines, except one, which lacked detectable p21(Waf1/Cip1) expression. Number of viable cells was not altered and no apoptotic cells were seen 24 h after p53 delivery. These results show, that wild-type p53 potently inhibits expression of MMP-13 and MMP-1 by SCC cells independently of its pro-apoptotic effect. Together these results indicate, that p53 exerts a bi-phasic tumor suppressor effect on SCC cells: inhibition of cell invasion followed by induction of programmed cell death.

Abstract
Matrix metalloproteinases (MMPs) are proteolytic enzymes capable of degrading extracellular matrix. Their role has been emphasized in tumor invasion, metastasis and tumor-induced angiogenesis. We studied the expression of collagenase-1 (MMP-1), stromelysin-1 (MMP-3) and collagenase-3 (MMP-13) in 70 melanoma metastases obtained from 56 patients treated with combined chemoimmunotherapy. The patients were divided into 2 groups using a cut-off point of 0% for MMP-1 expression and 20% for MMP-3 expression. We found that patients with MMP-1 positive metastases (n = 38) had significantly shorter disease-free survival compared to patients with MMP-1 negative metastases (n = 18) (median 11.2 vs. 17.0 months, p = 0.0383). The disease-free survival of patients with high levels of MMP-3 expression in their metastases (> or = 20% positive tumor cells, n = 14) was also significantly shorter compared to patients with lower levels of expression (n = 42) (median 5.1 vs. 14.0 months, p = 0.0294). The expression of MMP-13 did not correlate to survival parameters. We also found that the presence of melanin, a pigment produced by melanocytes, correlated with high expression levels of MMP-1 (p = 0.0002), MMP-3 (p < 0.0001) and MMP-13 (p = 0.0009). The high expression levels of MMP-13 were also associated with the presence of visceral metastases (p = 0.0284). Our findings suggest that MMP-1 and -3 may have a special role in melanoma metastasis formation and thus they could be used to measure the biological activity of the disease.

Abstract
Collagenase-3 (MMP-13) is characterized by an exceptionally wide substrate specificity and restricted expression. MMP-13 is 1 of the few MMPs primarily expressed by tumor cells in malignant tumors, e.g., squamous cell carcinomas and its expression correlates with their invasion capacity. In this work, we have constructed an expression vector and a recombinant adenovirus harboring human MMP-13 cDNA to investigate the role of MMP-13 in cancer cell invasion. Our results show that constitutive expression of MMP-13 by HT-1080 cells stably transfected with MMP-13 expression vector or transduced with MMP-13 adenovirus markedly increased their invasion both through type I collagen and reconstituted basement membrane (Matrigel) with no alterations in expression or activation of collagenase-1 (MMP-1), gelatinase-A (MMP-2), or gelatinase-B (MMP-9). The enhanced invasion capacity of MMP-13 expressing HT-1080 cells was dependent on MMP activity, as it was blocked by MMP inhibitor Batimastat (BB-94) and tissue inhibitor of metalloproteinases-3 (TIMP-3). Our data provide direct evidence for the role of MMP-13 as a potent invasion proteinase, which alone can enhance the ability of malignant cells to penetrate through both basement membrane and fibrillar collagen.
