Abstract
Matrix metalloproteinases (MMPs) are essential proteins acting directly in the breakdown of the extra cellular matrix and so in cancer invasion and metastasis. Given its impact on tumor angiogenesis, monitoring MMP-14 provides strategic insights on cancer severity and treatment. In this work, we report a new approach to improve the electrochemical interaction of the MMP-14 with the electrode surface while preserving high specificity. This is based on the detection of the hemopexin (PEX) domain of MMP-14, which has a greater availability with a stable and low-cost commercial molecule, as a recognition element. This molecule, called NSC-405020, is specific of the PEX domain of MMP-14 within the binding pocket. Through the covalent grafting of the NSC-405020 molecule on carbon nanotubes (CNTs), we were able to detect and quantify MMP-14 using electrochemical impedance spectroscopy with a linear range of detection of 10 ng⋅mL-1 to 100 ng⋅mL-1, and LOD of 7.5 ng⋅mL-1. The specificity of the inhibitory small molecule was validated against the PEX domain of MMP-1. The inhibitor loaded CNTs system showed as a desirable candidate to become an alternative to the conventional recognition bioelements for the detection of MMP-14.

Abstract
Background To evaluate role of microRNA (miRNA)-377-3p on the remission of ovarian cancer (OC) cell proliferation, invasion, and interstitial transition in vivo and vitro. Methods SKOV3 cells were used as the object of in vitro research and four-week-old immunodeficient BABL/c female nude mice were used to form the xenograft model. Cell models were constructed by transfecting NC mimics, miR-377 mimic, plasmid cloning DNA (pcDNA), pc-matrix metalloproteinase (MMP)-16, or co-transfecting miR-377 mimic and pc-MMP-16. TargetScan software was used to predict the targeting relationship between miRNA-377-3p and MMP-16 in OC cells. The combination of miRNA-377-3p and MMP-16 was detected by dual luciferase report experiment. miRNA expression levels of miRNA-377-3p and MMP-16 in each transfection group cells were detected by reverse transcription-polymerase chain reaction (RT-PCR). The proliferation of SKOV3 cells were assessed by 5-ethynyl-2'-deoxyuridine (EdU) staining and microtubule formation, while the invasion ability of SKOV3 cells was detected by Transwell assay. Protein expression levels of MMP-16, survivin, Ki67, vascular endothelial growth factor (VEGF), E-cadherin, and N-cadherin were detected by Western blot (WB), and the positive cells of Ki67 and VEGF were detected by immunohistochemistry (IHC). Results MMP-16 overexpression markedly increased the EDU-positive cell percentage, upregulated survivin and Ki67 levels, increased the number of invasive cells per field, and enhanced VEGF and N-cadherin expression. Importantly, co-transfection of miRNA-377-3p and MMP-16 reversed these abnormal phenomena. Xenotransplantation mouse models were formed by injecting SKOV-3 cells subcutaneously. Tumor size, tumor volume, and tumor weight were all reduced in the miR-377-3p mimic–transfected group. The results of IHC indicated that Ki67 and VEGF expression were decreased in the miR-377-3p mimic–transfected group. Conclusions These findings indicate that miR-377-3p could be a promising therapeutic agent for OC cell growth, invasion, and interstitial transition with MMP-16 being its likely target.

Abstract
CD100 is an immune semaphorin constitutively expressed on T-cells. Matrix metalloproteinase (MMP) is an important mediator of membrane-bound CD100 (mCD100) cleavage to generate soluble CD100 (sCD100), which has immunoregulatory activity in immune cell responses. The aim of the study was to investigate the level and role of sCD100 and mCD100 in modulating CD8+ T-cell function in non-small cell lung cancer (NSCLC). sCD100 and MMP-14 levels in the serum and bronchoalveolar lavage fluid (BALF), and mCD100 expression on peripheral and lung-resident CD8+ T-cells were analysed in NSCLC patients. The ability to induce sCD100 and the effect of MMP-14 on mCD100 shedding for the regulation of non-cytolytic and cytolytic functions of CD8+ T-cells were also analysed in direct and indirect contact co-culture systems. NSCLC patients had lower serum sCD100 and higher mCD100 levels on CD8+ T-cells compared with healthy controls. BALF from the tumour site also had decreased sCD100 and increased mCD100 on CD8+ T-cells compared with the non-tumour site. Recombinant CD100 stimulation enhanced non-cytolytic and cytolytic functions of CD8+ T-cells from NSCLC patients, whereas blockade of CD100 receptor CD72 attenuated CD8+ T-cell activity. NSCLC patients had lower MMP-14 in the serum and in BALF from the tumour site. Recombinant MMP-14 mediated mCD100 shedding from CD8+ T-cell membrane, and led to promotion of CD8+ T-cell response in NSCLC patients. Overall, decreased MMP-14 resulted in insufficient CD100 shedding, leading to suppression of peripheral and lung-resident CD8+ T-cell activity in NSCLC.

Abstract
COPD, characterized by long-term poorly irreversible airway limitation and persistent respiratory symptoms, has resulted in enormous challenges to human health worldwide, with increasing rates of prevalence, death, and disability. Although its origin was thought to be in the interactions of genetic with environmental factors, the effects of environmental factors on the disease during different life stages remain little known. Without clear mechanisms and radical cure for it, early screening and prevention of COPD seem to be important. In this review, we will discuss the etiologic origins for poor lung function and COPD caused by specific adverse effects during corresponding life stages, as well as try to find new insights and potential prevention strategies for this disease.

Abstract
Membrane type matrix metalloproteinases (MT-MMPs) play important roles in malignant tumor progression through the degradation of the extracellular matrix and signal transduction. However, a member of the family, MT3-MMP, has attracted the least concern compared with other MT-MMPs. Here, a novel MT3-MMP-targeting peptide with high affinity and specificity has been developed by a phage-display peptide screening technology and multiple biophysics measurements, including single-molecule recognition force spectroscopy and isothermal titration calorimetry. The binding peptides are conjugated on the surface of CdSe/ZnS quantum dots (QDs) and consequently acted as a ligand that specifically targets MT3-MMP overexpressed tumor cells. The imaging nanoprobes used QDs as the photographic developer for optical imaging in vivo. The nanoprobes exhibited a desirable targeting effect and generated good biodistribution profiles for visualization and imaging of MT3-MMP overexpressed tumor. The peptide could be useful to evaluate the distribution and expression of MT3-MMP. Furthermore, the peptide-functionalized QDs show potential application for cancer diagnosis.

Abstract
Tumor cells are hypothesized to use proteolytic enzymes to facilitate invasion. Whether circulating tumor cells (CTCs) secrete these enzymes to aid metastasis is unknown. A quantitative and high-throughput approach to assay CTC secretion is needed to address this question. We developed an integrated microfluidic system that concentrates rare cancer cells >100,000-fold from 1 mL of whole blood into ∼50,000 2-nL drops composed of assay reagents within 15 min. The system isolates CTCs by size, exchanges fluid around CTCs to remove contaminants, introduces a matrix metalloprotease (MMP) substrate, and encapsulates CTCs into microdroplets. We found CTCs from prostate cancer patients possessed above baseline levels of MMP activity (1.7- to 200-fold). Activity of CTCs was generally higher than leukocytes from the same patient (average CTC/leukocyte MMP activity ratio, 2.6 ± 1.5). Higher MMP activity of CTCs suggests active proteolytic processes that may facilitate invasion or immune evasion and be relevant phenotypic biomarkers enabling companion diagnostics for anti-MMP therapies.

Abstract
Normal gas exchange after birth requires functional lung alveolar units that are lined with epithelial cells, parts of which are intricately fused with microvascular capillaries. A significant phase of alveolar lung development occurs in the perinatal period, continues throughout early stages in life, and requires activation of matrix-remodeling enzymes. Failure to achieve an optimum number of alveoli during lung maturation can cause several untoward medical consequences including disabling obstructive and/or restrictive lung diseases that limit physiological endurance and increase mortality. Several members of the matrix metalloproteinase (MMP) family are critical in lung remodeling before and after birth; however, their resurgence in response to environmental factors, infection, and injury can also compromise lung function. Therefore, temporal expression, regulation, and function of MMPs play key roles in developing and maintaining adequate oxygenation under steady state, as well as in diseased conditions. Broadly, with the exception of MMP2 and MMP14, most deletional mutations of MMPs fail to perturb lung development; however, their individual absence can alter the pathophysiology of respiratory diseases. Specifically, under stressed conditions such as acute respiratory infection and allergic inflammation, MMP2 and MMP9 can play a protective role through bacterial clearance and production of chemotactic gradient, while loss of MMP12 can protect mice from smoke-induced lung disease. Therefore, better understanding of the expression and function of MMPs under normal lung development and their resurgence in response respiratory diseases could provide new therapeutic options in the future.

Abstract
While commonly known for degradation of the extracellular matrix, matrix metalloproteinases (MMPs) exhibit broad potential for use in targeting of bioactive and imaging agents in cancer treatment. MMPs are upregulated at all stages of expression in cancers. A comprehensive analysis of published literature on expression of all MMP subtypes at the genetic, protein, and activity levels in normal and diseased tissues indicate targeting applicability in a variety of cancers. This expression significantly increases at advanced cancer stages, providing an improved opportunity for controlled release in higher-stage patients. Since MMPs are integral at every stage of metastasis, MMP roles in cancer are discussed with a focus on MMP distribution and mobility within cells and tumors for cancer targeting applications. Several strategies for MMP utilization in targeting - such as matrix degradation, MMP cleavage, MMP binding, and MMP-induced environmental changes - are addressed.

Abstract
Lung cancer is the most common cause of death in men and second only to breast cancer in women. MicroRNAs (miRNAs) are involved in tumorigenesis and function as oncogenes or tumor suppressor genes. Among other genes, miRNAs regulate matrix metalloproteinases (MMPs), the proteolytic enzymes playing a significant role in the degradation of extracellular matrix, enhancing tumor invasion and metastasis. The aim of the study was to evaluate the expression levels of selected miRNAs: miR-26a, miR-29b and miR-519d, and their target gene, matrix metalloproteinase-2 (MMP-2) in patients with non-small cell lung cancer (NSCLC). The results were correlated with tumor staging, NSCLC histopathological subtypes and patients' demographical features to assess the possible diagnostic/prognostic value of the studied miRNAs and MMP-2. Total RNA was isolated from 38 NSCLC tissue samples, and the expression analysis was performed using TaqMan(®) probes in qPCR assay. The results indicated underexpression of selected miRNAs and overexpression of MMP-2. The decrease in miRNA-29b expression was statistically significant and differentiated NSCLC histopathological subtypes. Additionally, statistically significant negative correlation was found between MMP-2 expression and its regulatory miR-26a. There are very few studies reporting miRNA-MMPs analysis on mRNA level in lung cancer, and no similar reports are available from Polish population. The results of our pilot study indicated the diagnostic potential of miR-29b and MMP-2, an inverse association between miR-26a and MMP-2, and proved the role of MMP-2 and the studied miRNAs in lung carcinogenesis. Further studies are needed to verify their potential usefulness for the treatment of lung cancer.

Abstract
Lung cancer (LuCa) is the leading cause of cancer-related deaths worldwide regardless of the gender. High mortality associated with LuCa is due to metastasis, molecular mechanisms of which are yet to be defined. Here, we present evidence that chemokine receptor CXCR6 and its only natural ligand, CXCL16, are significantly expressed by non-small cell lung cancer (NSCLC) and are involved in the pathobiology of LuCa. CXCR6 expression was significantly higher in two subtypes of NSCLC (adenocarcinomas-ACs and squamous cell carcinoma-SCCs) as compared to non-neoplastic tissue. Additionally, serum CXCL16 was significantly elevated in LuCa cases as compared to healthy controls. Similar to CXCR6 tissue expression, serum level of CXCL16 in AC patients was significantly higher than SCC patients. Biological significance of this axis was validated using SCC and AC cell lines. Expression of CXCR6 was higher in AC cells, which also showed higher migratory and invasive potential than SCC. Differences in migratory and invasive potential between AC and SCC were due to differential expression of metalloproteinases following CXCL16 stimulation. Hence, our findings suggest clinical and biological significance of CXCR6/CXCL16 axis in LuCa, which could be used as potential prognostic marker and therapeutic target.

Abstract
The Notch pathway contributes to self-renewal of tumor-initiating cell and inhibition of normal colonic epithelial cell differentiation. Deregulated expression of Notch1 and Jagged1 is observed in colorectal cancer. Hairy/enhancer of split (HES) family, the most characterized targets of Notch, involved in the development of many cancers. In this study, we explored the role of Hes1 in the tumorigenesis of colorectal cancer. Knocking down Hes1 induced CRC cell senescence and decreased the invasion ability, whereas over-expression of Hes1 increased STAT3 phosphorylation activity and up-regulated MMP14 protein level. We further explored the expression of Hes1 in human colorectal cancer and found high Hes1 mRNA expression is associated with poor prognosis in CRC patients. These findings suggest that Hes1 regulates the invasion ability through the STAT3-MMP14 pathway in CRC cells and high Hes1 expression is a predictor of poor prognosis of CRC.

Abstract
Since the processing activity of the matrix metalloproteinase MT1-MMP regulates various cellular functions such as motility, invasion, growth, differentiation and apoptosis, precise in vivo evaluation of MT1-MMP activity in cancers can provide beneficial information for both basic and clinical studies. For this purpose, we designed a cleavable Positron Emission Tomography (PET)/optical imaging probe consisting of BODIPY650/665 and polyethylene glycol (PEG) conjugated to opposite ends of MT1-MMP substrate peptides. We used in vitro and in vivo fluorescence experiments to select suitable substrate peptide sequences and PEG sizes for the MT1-MMP probes and obtained an optimized structure referred to here as MBP-2k. Radiofluorinated MBP-2k ([(18)F]MBP-2k) was then successfully synthesized via an (18)F-(19)F isotopic exchange reaction in BODIPY650/665. After intravenous injection into mice with xenografted tumors, [(18)F]MBP-2k showed significantly higher accumulation in HT1080 tumors with high MT1-MMP activity than in A549 tumors that have low MT1-MMP activity. Moreover, PET images showed better contrast in HT1080 tumors. These results show that [(18)F]MBP-2k can be used as a hybrid PET/optical imaging agent and is a promising probe for non-invasive monitoring of MT1-MMP activity in cancers. This probe may also efficiently combine targeted tumor imaging with image-guided surgery that could be beneficial for patients in the future.

Abstract
Although matrix metalloproteinase 14 (MMP-14) has been shown to play a substantial role in the carcinogenesis of some types of cancer, its involvement in the pathogenesis of nasopharyngeal carcinoma (NPC) has not been reported. Here, we analyzed MMP-14 levels in the NPC specimens from patients and compared with the paired normal nasopharynx (NNP) tissues. We found that NPC had significantly higher messenger RNA (mRNA) and protein levels of MMP-14. Moreover, higher levels of MMP-14 correlated with more advanced status of clinical stage and lymphatic metastasis. In vitro, MMP-14 levels determined the potential of invasiveness of NPC cells, possibly through induction of EMT-associated genes. Our data thus highlight MMP-14 as a novel therapeutic target for NPC.

Abstract
Membrane type 1-matrix metalloproteinase (MT1-MMP) has been identified to play a significant role in several types of cancers, but little is known about the significance of MT1-MMP in gastric cancer patients. The purpose of this study is to investigate the involvement of MT1-MMP in tumor progression of gastric cancer. MT1-MMP expression levels were examined in gastric cancer tissues and cells, and normal gastric tissues and cells. The effects and molecular mechanisms of MT1-MMP expression on cell proliferation, migration, and invasion were also explored. In our results, MT1-MMP messenger RNA (mRNA) and protein expression levels were significantly increased in gastric cancer tissue. Moreover, the overexpression of MT1-MMP was positively associated with the status of clinical stage and lymph node metastasis through real-time PCR. Furthermore, knocking down MT1-MMP expression significantly suppressed the cell migration and invasion in vitro and regulated the expression of MMPs and epithelial-mesenchymal transition (EMT)-associated genes. In conclusions, our study demonstrates that MT1-MMP was overexpressed in gastric cancer tissue, and reduced expression of MT1-MMP suppressed cell migration, invasion, and through regulating the expression of MMPs and the process of EMT in gastric cancer.

Abstract
Activatable cell-penetrating peptides (aCPPs) allow non-viral, low cytotoxic and selective delivery of compounds into target cells for cancer therapy. In tumour cells, up-regulation of human telomerase reverse transcriptase (hTERT) frequently occurs and is being considered as a target in cancer diagnosis and treatment. siRNA sequence that target hTERT mRNA can silence the gene and reduce hTERT protein expression to reduce cell proliferation and inhibit cell growth. In our study, we tested a matrix metalloproteinase-2 (MPP2) aCPP in delivering hTERT siRNA into hepatocellular carcinoma cells (SMMC-7721) to silence the hTERT gene. Cultured SMMC-7721 cells were transfected with a complex of aCPPs and hTERT-specific siRNA-encoding or control plasmids. Compared with cells treated with the complex of control plasmid–CPPs, cells treated with the hTERT-specific siRNA-encoding plasmid–CPP complex had a prolonged G1-phase, but a shorter G2/S-phase, indicating a G1-arrest. Treatment with the hTERT-specific siRNA resulted in a significant decrease (by 26%; P<0.05) in hTERT mRNA levels. The aCPPs tested in this study provides a non-viral delivery of siRNA into cancer cells to silence target genes in cancer therapy. In the present study, we delivered human telomerase reverse transcriptase (hTERT) siRNA into SMMC-7721 hepatoma cells using a matrix metalloproteinase-2 (MMP2)-activatable cell-penetrating peptide (aCPP). The siRNA subsequently induced down-regulation of the hTERT gene and G1-arrest, implicating the utility of this delivery system in cancer therapy.

Abstract
MT1-MMP exhibits diverse expressions in patients with cancer and could be considered as potential prognostic biomarker of cancer. We performed a meta-analysis aiming to provide more sufficient evidence that MT1-MMP expression is associated with poor overall survival in several types of cancers. We systematically searched the studies from databases and carefully identified based on eligibility criteria. The association between MT1-MMP expression and overall survival in cancers was estimated using Review Manager. A total of 11 literatures which included 1,918 cancer patients were combined in the final analysis. Meta-analysis revealed that MT1-MMP overexpression was associated with an unfavorable overall survival and the pooled hazard ratio (HR) and corresponding 95 % confidence interval (CI) was 2.46 (95 % CI 1.75-3.47). From subgroup analyses, we identified that MT1-MMP was an independent prognostic factor for lung cancer and gastric cancer, and HRs (95 % CI) were 3.73 (95 % CI 2.67-5.21) and 2.46 (95 % CI 1.69-3.59), respectively. In conclusion, MT1-MMP is a potential prognostic factor in human cancers.

Abstract
Matrix metalloproteinase-14 (MMP-14) has been demonstrated to play an important role in tumor progression. The aim of this study was to analyze the correlation between MMP-14 expression and clinicopathologic features and its prognostic significance in non-small cell lung cancer (NSCLC). Immunohistochemical staining for MMP-14 protein was performed in 104 patients with NSCLC. High levels of MMP-14 protein were positively correlated with the status of clinical stage (I-II vs. III-IV; P < 0.001), N classification (N0-N1 vs. N2-N3; P < 0.001), distant metastasis (no vs. yes; P = 0.014), and differentiated degree (high vs. low or undifferentiated; P = 0.001). The patients with higher MMP-14 expression of protein had shorter survival time than patients with low MMP-14 expression. Multivariate analysis indicated that the level of MMP-14 expression was an independent prognostic indicator (P < 0.001) for the survival of patients with NSCLC. In conclusion, MMP-14 is a potential unfavorable prognostic factor for patients with NSCLC.

Abstract
Development of therapeutic strategies for tumor-selective delivery of therapeutics through exploitation of the proteolytic tumor phenotype has significant scope for improvement of cancer treatment. ICT2588 is a peptide-conjugated prodrug of the vascular disrupting agent (VDA) azademethylcolchicine developed to be selectively hydrolyzed by matrix metalloproteinase-14 (MMP-14) within the tumor. In this report, we extend our previous proof-of-concept studies and demonstrate the therapeutic potential of this agent against models of human colorectal, lung, breast, and prostate cancer. In all tumor types, ICT2588 was superior to azademethylcolchicine and was greater or comparable to standard clinically used agents for the respective tumor type. Prodrug activation in clinical human lung tumor homogenates relative to stability in human plasma and liver was observed, supporting clinical translation potential. A major limiting factor to the clinical value of VDAs is their inherent cardiovascular toxicity. No increase in plasma von Willebrand factor (vWF) levels, an indicator of systemic vascular dysfunction and acute cardiovascular toxicity, was detected with ICT2588, thereby supporting the tumor-selective activation and reduced potential of ICT2588 to cause cardiovascular toxicity. Our findings reinforce the improved therapeutic index and tumor-selective approach offered by ICT2588 and this nanotherapeutic approach.

Abstract
It has been previously reported that vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP)-9 are important for the occurrence and development of non-small cell lung cancer (NSCLC). The present study was designed to detect the serum levels of VEGF and MMP-9 in NSCLC, and to explore their diagnostic and prognostic values. A total of 543 cases were involved, of which 332 were NSCLC (272 cases in the pretreatment group and 60 cases in the postoperative group), 91 were patients with benign lung diseases and 120 were healthy controls. The serum levels of VEGF and MMP-9 were determined by Luminex multiplex technology. The serum levels of VEGF and MMP-9 were found to be significantly higher in the pretreatment group than those in the patients with benign lung diseases and healthy controls (VEGF, P<0.0001; MMP-9, P<0.0001). Compared with the pretreatment group, the serum levels of VEGF and MMP-9 in the postoperative group were significantly decreased (VEGF, P=0.005; MMP-9, P=0.002), and the levels of VEGF and MMP-9 in the pretreatment group of patients with stages III and IV were higher than those with stages I and II (VEGF, P<0.0001; MMP-9, P=0.021). In addition, the levels of VEGF and MMP-9 were found to closely correlate with lymph node metastasis (VEGF, P<0.0001; MMP-9, P<0.0001) in the pretreatment group, while being independent of other clinicopathological parameters (P>0.05). Furthermore, a positive correlation was observed between the serum levels of VEGF and MMP-9 (r=0.159; P=0.009). A receiver operating characteristic curve analysis showed that the diagnostic value of MMP-9 was higher than that of VEGF in the pretreatment group. The log-rank test indicated that the inoperable NSCLC patients with low levels of VEGF exhibited a significantly longer overall survival time than those with high VEGF levels (P<0.0001). Additionally, the serum levels of VEGF and lymph node metastasis were identified as independent prognostic factors of the inoperable NSCLC patients in a multivariate Cox regression analysis (P<0.05). These results indicated that VEGF and MMP-9 may be potential biomarkers for the diagnosis and prognosis of NSCLC.

Abstract
Lung cancer is the leading cause of cancer‑related mortality worldwide. Over half of lung cancer cases are diagnosed after metastasis, for which the median survival time is approximately 8 months. microRNAs (miRNAs), which are a class of single‑stranded endogenous non‑coding RNAs, are likely to be involved in most biological processes. miR‑133 plays roles in cardiac development and disease, and recent studies showed that miR‑133 is downregulated in various human malignancies, such as bladder and lung cancer. However, its detailed role in the processes of cancer remains to be determined. In the present study, we found that in the lung cancer cell lines A549 and NCI‑H1299 overexpression of miR‑133a suppressed cell proliferation, migration and invasion. The miR‑133a‑induced suppression of cell migration and invasion can be reversed by miR‑133a‑specific inhibitor. According to the mRNA sequence, matrix metalloproteinase (MMP)‑14, which is an important regulator of metastasis, is a predicted target of miR‑133a. This was confirmed by dual luciferase reporter assay. Moreover, miR‑133a overexpression decreases the mRNA and protein levels of MMP‑14. Collectively, these results suggest that miR‑133a may inhibit lung cancer metastasis by targeting MMP‑14 and may be used as an anti‑metastatic therapy in lung cancer patients.

Abstract
BACKGROUND The matrix metalloproteinases (MMPs)-2, -9 and -7 are thought to be associated with tumor invasion, metastasis, and angiogenesis. However, their possible roles in early-stage lung cancer are not clear. We measured the activity of MMP-2, -7 and -9 in early-stage lung cancer tissues. MATERIAL AND METHODS Normal lung tissues and cancer tissues were collected from 60 consecutive stage-I non-small cell lung cancer (NSCLC) patients. The activities of MMP-2 and MMP-9 were determined by gelatin zymography, and the activity of MMP-7 was determined by casein zymography. Furthermore, the ratio of the active form of MMP-2 in tumor tissue (T) compared with normal tissue (N) was determined, and the survival in the groups with different MMP-2 T:N ratio was compared. RESULTS The activity of both MMP-2 and MMP-9 was detected in all cancer and normal tissues. Interestingly, MMP-9 activity was significantly reduced, whereas MMP-2 activity was significantly increased, in cancer tissues compared to normal tissues. The survival rate of the MMP-2 T:N ratio > 2.5 group was 57.45%, which was significantly reduced compared with that of the T:N ratio ≤ 2.5 group (86.78%). CONCLUSION Our findings suggest that MMP-2, but not MMP-9 and MMP-7, may be implicated in early-stage tumor invasion, metastasis, and angiogenesis in NSCLC.

Abstract
BACKGROUND Matrix metalloproteases (MMPs) are key players in the progression and metastasis of cancer. MMPs cleave extracellular matrix components and in this way promote tumor growth, invasion and vascularization. MMPs also affect tumor progression by regulating availability and activity of growth factors, inflammatory cytokines and chemokines. Accordingly, several MMPs have been found to serve as prognostic indicators in solid tumors. Usually the increased levels of MMPs in patients' tumor tissue or serum/plasma are associated with poor outcome. Interestingly, recent results show that certain MMPs also serve as tumor suppressors. OBJECTIVE This review discusses the latest view on MMPs as diagnostic and prognostic indicators in cancer patients. METHODS Studies with clinical samples of 70 or more patients are included in particular. In addition, the possible roles of MMPs in future molecular diagnostics and in the evaluation of therapeutic responses are discussed. CONCLUSION MMP-9 in particular has shown prognostic value in various types of tumor, and its measurement in circulation, urine or tumor tissue might help in clinical surveillance of otherwise problematic patient cases. There is upcoming new knowledge on MMPs in therapy response evaluation, in which MMPs might be useful together with CT scans and other clinically more established prognostic factors. Certain MMPs have a dual role in terms of cancer-modulating properties and thus it is essential to evaluate their expression and function in tumor cells and host environment to select validated therapy targets but spare MMP antitargets.

The system of PCs is involved in carcinogenesis and levels of PC mRNAs alter in cancer, which suggests expression status of PCs as a possible marker for cancer typing and prognosis. The goal of this work was to assess the information value of expression profiling of PC genes. Quantitative polymerase chain reaction was used for the first time to analyze mRNA levels of all PC genes as well as matrix metalloproteinase genes MMP2 and MMP14, which are substrates of PCs, in 30 matched pairs of samples of human lung cancer tumor and adjacent tissues without pathology. Significant changes in the expression of PCs have been revealed in tumor tissues: increased FURIN mRNA level (p<0.00005) and decreased mRNA levels of PCSK2 (p<0.007), PCSK5 (p<0.0002), PCSK7 (p<0.002), PCSK9 (p<0.00008), and MBTPS1 (p<0.00004) as well as a tendency to increase in the level of PCSK1 mRNA. Four distinct groups of samples have been identified by cluster analysis of the expression patterns of PC genes in tumor vs. normal tissue. Three of these groups covering 80% of samples feature a strong elevation in the expression of a single gene in cancer: FURIN, PCSK1, or PCSK6. Thus, the changes in the expression of PC genes have a limited number of scenarios, which may reflect different pathways of tumor development and cryptic features of tumors. This finding allows to consider the mRNAs of PC genes as potentially important tumor markers.

Abstract
Despite tremendous advances in cancer treatment and survival rates, pancreatic cancer remains one of the most deadly afflictions and the fourth leading cause of cancer deaths in the world. Matrix Metalloproteinases (MMPs) are thought to be involved in cancer progression. Matrix metalloproteinase (MMP)-2 is known to play a pivotal role in tumor invasion, metastasis and angiogenesis, and validated to be the anticancer target. Inhibition of MMP-2 activity is able to reduce the cancer cell invasion and suppress tumor growth in vivo. Two novel peptides, M204C4 and M205C4, which could specially inhibit MMP-2 activity, were identified by a phage display library screening. We showed that M204C4 and M205C4 inhibited the activity of MMP-2 in a dose dependent manner in vitro. Two peptides reduced MMP-2 mediated invasion of the pancreatic cancer cell lines PANC-1 and CFPAC-1, but not affected the expression and release of MMP-2. Furthermore, these two peptides could suppress tumor growth in vivo. Our results indicated that two peptides selected by phase display technology may be used as anticancer drugs in the future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Diosgenyl and pennogenyl saponins isolated from Rhizoma Paridis, showed pro-apoptosis and immunoregulation with antitumor activity in cultured cells and animal systems. AIM OF THE STUDY To evaluate their anti-metastatic mechanism on cancer cells and discuss their structure-activity relationship on anti-tumor effect. MATERIALS AND METHODS This research used the wound healing and migration assay to detect their anti-invasive effect on B16 melanoma cells. Through the gelatin zymography assay, immunofluorescence analysis and western blot, saponins exhibited different levels of protein expression inhibition of MMP-1, -2, -3, -9 and -14. RESULTS Through the analysis, diosgenyl and pennogenyl saponins inhibited the metastasis of B16 melanoma cells. Diosgenyl saponins also showed strong suppression of enzyme activity of MMP-2 and -9. Different saponins exhibited different levels of inhibition on MMP expression. CONCLUSIONS 17-α OH increases the sensitivity of diosgenyl saponins to the membrane-bound protease which can stimulate proMMP-2 activation, but it also decreases the anti-metastatic activity of diosgenyl saponin. Furthermore, their combination might provide a potential therapeutic modality for metastasis.

Abstract
Directed evolution was applied to identify peptide substrates with enhanced hydrolysis rates by MT1-MMP suitable for protease beacon development. Screening of a random pentapeptide library, using two-color CLiPS, yielded several substrates identical to motifs in distinct collagens that shared the consensus sequence P-x-G↓L. To identify substrates with enhanced cleavage rates, a second-generation decapeptide library incorporating the consensus was screened under stringent conditions, which resulted in a MxPLG↓(M)/(L)M(G)/(A)R consensus motif. These substrates are hydrolyzed by human-MT1-MMP up to six times faster than reported peptide substrates and are stable in plasma. Finally, incubation of soluble protease beacons incorporating the optimized substrates, but not previous substrates, enabled direct detection of endogenous MT1-MMP activity of human-fibrosarcoma (HT-1080) cells. Extended substrate libraries coupled with CLiPS should be useful to generate more effective activity probes for a variety of proteolytic enzymes.

Abstract
Hypoxia is a critical event in solid tumor development, invasion, and metastasis. Cellular adaptation to hypoxic microenvironment is essential for tumor progression and is largely mediated by hypoxia-inducible factor-1α (HIF-1α) through coordinated regulation of hypoxia-responsive genes. In this study, we found that membrane type-2 matrix metalloproteinase (MT2-MMP), one of the matrix metalloproteinase (MMP) family members, was a novel hypoxia-responsive gene and was upregulated by HIF-1α under hypoxia. When cancer cells were subjected to hypoxia (1% O(2) ) treatment, the mRNA and protein levels of MT2-MMP were significantly increased in a time-dependent manner in all three tested cancer cell lines including pancreatic cancer cells (PANC-1), nonsmall cell lung cancer cells (A-549), and cervix cancer cells (HeLa). Further analyses indicated that there were two hypoxia-responsive elements (HREs) in the MT2-MMP promoter, and HRE1 but not HRE2 was essential for MT2-MMP transcriptional activation under hypoxia. HIF-1α specifically and directly bound to MT2-MMP promoter was analyzed by HIF-1α binding/competition and chromatin immunoprecipitation (ChIP) assays. Furthermore, we found that upregulation of MT2-MMP under hypoxia could confer resistance to hypoxia-induced apoptosis and increase invasiveness of cancer cells. These findings provided a new insight into how cancer cells overcome hypoxic stress and trend to survive and invade, demonstrated a new regulatory mechanism of MT2-MMP expression in caner cells, and also revealed that MT2-MMP was a novel hypoxia-responsive gene and was upregulated by HIF-1α under hypoxia. © 2011 Wiley-Liss, Inc.

Abstract
BACKGROUND Matrix metalloproteinases are members of a large family of endopeptidases that participate in the extracellular-matrix degradation that accompanies cancer cell invasion, metastasis and angiogenesis. The membrane-type 1 matrix metalloproteinase (MT1-MMP) gene has been reported in various cancers and is associated with tumor invasion and metastasis. This study examined the relation of the relative expression of MT1-MMP gene to clinicopathological factors and outcomes in patients with colorectal cancer (CRC). METHODS We studied surgical specimens of cancer tissue and adjacent normal mucosa obtained from 202 patients with untreated CRC. The relative expression levels of MT1-MMP mRNA in cancer and in normal adjacent mucosa were measured by quantitative real-time reverse-transcriptase polymerase chain reaction. RESULTS MT1-MMP gene expression was higher in cancer tissue than in adjacent normal mucosa. The level of MT1-MMP gene expression was not related to any clinicopathological factor. Overall survival at 5 years differed significantly between patients with high MT1-MMP gene expression and those with low expression. CONCLUSIONS Overexpression of the MT1-MMP gene is considered a useful independent predictor of outcomes in patients with CRC.

Abstract
MMP intervention strategies have met with limited clinical success due to severe toxicities. In particular, treatment with broad-spectrum MMP-inhibitors (MMPIs) caused musculoskeletal pain and inflammation. Selectivity may be essential for realizing the clinical potential of MMPIs. Here we review discoveries pinpointing membrane-bound MMPs as mediators of mechanisms underlying cancer and inflammation and as possible therapeutic targets for prevention/treatment of these diseases. We discuss strategies to target these therapeutic proteases using highly selective inhibitory agents (i.e., human blocking antibodies) against individual membrane-bound MMPs.

MT1-MMP plays an important role in an invasive activity of malignant pleural mesothelioma cell. Exp Mol Pathol 2010; 90:91-6.

Abstract
Malignant pleural mesothelioma (MPM) has a poor prognosis and is a treatment resistant tumor, which is increasing in frequency throughout the world. The poor prognosis is due to the aggressive local invasiveness rather than distant metastasis. In this study, we established a cell line of malignant mesothelioma from a clinical specimen and assessed the relationship between the expression of MT1-MMP and the invasion ability of that line, as well as the cultured cells of several other lines, using the simple method that we created previously. We established a cell line from a clinical specimen from a patient with malignant mesothelioma. We assessed the invasive activities of MPM cells in an easy-to-prepare double-layered collagen gel hemisphere (DL-CGH) system that enabled us to visualize cell movements during invasion. To assess the role of MT1-MMP in the invasive activity of MPM cells, we knocked down its expression by RNA interference (RNAi). The invasion assay with DL-CGH revealed that a high expression of MT1-MMP in MPM cells was associated with aggressive invasive activity. The RNAi of MT1-MMP indicated that the expression of MT1-MMP might have a crucial role in the invasiveness of MPM cells. The MT1-MMP expression in MPM cells is related to their capacity for locally aggressive spreading into the pleura and the surrounding tissues, and MT1-MMP should be a suitable molecular target for the suppression of the invasiveness of MPM.

Abstract
Vascular disrupting agents (VDA) offer a strategy to starve solid tumors of nutrients and oxygen concomitant with tumor shrinkage. Several VDAs have progressed into early clinical trials, but their therapeutic value seems to be compromised by systemic toxicity. In this report, we describe the design and characterization of a novel VDA, ICT2588, that is nontoxic until activated specifically in the tumor by membrane-type 1 matrix metalloproteinase (MT1-MMP). HT1080 cancer cells expressing MT1-MMP were selectively chemosensitive to ICT2588, whereas MCF7 cells that did not express MT1-MMP were nonresponsive. Preferential hydrolysis of ICT2588 to its active metabolite (ICT2552) was observed in tumor homogenates of HT1080 relative to MCF7 homogenates, mouse plasma, and liver homogenate. ICT2588 activation was inhibited by the MMP inhibitor ilomastat. In HT1080 tumor-bearing mice, ICT2588 administration resulted in the formation of the active metabolite, diminution of tumor vasculature, and hemorrhagic necrosis of the tumor. The antitumor activity of ICT2588 was superior to its active metabolite, exhibiting reduced toxicity, improved therapeutic index, enhanced pharmacodynamic effect, and greater efficacy. Coadministration of ICT2588 with doxorubicin resulted in a significant antitumor response (22.6 d growth delay), which was superior to the administration of ICT2588 or doxorubicin as a single agent, including complete tumor regressions. Our findings support the clinical development of ICT2588, which achieves selective VDA targeting based on MT-MMP activation in the tumor microenvironment.

Abstract
Matrix metalloproteases (MMPs) comprise a family of enzymes that cleave protein substrates based on a conserved mechanism involving activation of an active site-bound water molecule by a Zn(2+) ion. Although the catalytic domain of MMPs is structurally highly similar, there are many differences with respect to substrate specificity, cellular and tissue localization, membrane binding and regulation that make this a very versatile family of enzymes with a multitude of physiological functions, many of which are still not fully understood. Essentially, all members of the MMP family have been linked to disease development, notably to cancer metastasis, chronic inflammation and the ensuing tissue damage as well as to neurological disorders. This has stimulated a flurry of studies into MMP inhibitors as therapeutic agents, as well as into measuring MMP levels as diagnostic or prognostic markers. As with most protein families, deciphering the function(s) of MMPs is difficult, as they can modify many proteins. Which of these reactions are physiologically or pathophysiologically relevant is often not clear, although studies on knockout animals, human genetic and epigenetic, as well as biochemical studies using natural or synthetic inhibitors have provided insight to a great extent. In this review, we will give an overview of 23 members of the human MMP family and describe functions, linkages to disease and structural and mechanistic features. MMPs can be grouped into soluble (including matrilysins) and membrane-anchored species. We adhere to the 'MMP nomenclature' and provide the reader with reference to the many, often diverse, names for this enzyme family in the introduction.

Abstract
The purpose of this study was to examine the expression of MMP-14, 15 and 16 (MT1, MT2 and MT3-MMP) in supraglottic carcinoma and to explore their clinical significance. Expression of MMP-14, 15 and 16 was examined using RT-PCR and immunohistochemistry methods in samples from 85 cases of supraglottic carcinoma. Results showed that both mRNA and protein expression of MMP-14, 15 and 16 were increased in supraglottic carcinoma tissues compared to expression in control adjacent non-neoplastic tissues (P < 0.05). Expression of MMP-14, but not MMP-15 and MMP-16, was significantly increased in the T3 and neck nodal metastasis groups compared with the T1-2 group and the group without nodal metastasis at both mRNA and protein levels (P < 0.05). Expression of MMP-14 mRNA and protein was also higher in tumors of patients with stage III-IV disease compared to patients with clinical stage I-II tumors (P < 0.05). Kaplan-Meier survival curves showed that the groups with high MMP-14 protein expression had a poorer prognosis than patients in the groups with weak or negative expression of MMP-14 protein (P < 0.05). In conclusion, MMP-14 may play an important role in the progression of supraglottic carcinoma and may be a novel prognostic factor for patients with supraglottic carcinoma.

Abstract
Background Colorectal cancer is the second most common cause of cancer related death in the developed world. To date, no blood or stool biomarkers with both high sensitivity and specificity for potentially curable early stage disease have been validated for clinical use. SELDI and MALDI profiling are being used increasingly to search for biomarkers in both blood and urine. Both techniques provide information predominantly on the low molecular weight proteome (<15 kDa). There have been several reports that colorectal cancer is associated with changes in the serum proteome that are detectable by SELDI and we hypothesised that proteomic changes would also be detectable in urine. Results We collected urine from 67 patients with colorectal cancer and 72 non-cancer control subjects, diluted to a constant protein concentration and generated MALDI and SELDI spectra. The intensities of 19 peaks differed significantly between cancer and non-cancer patients by both t-tests and after adjusting for confounders using multiple linear regressions. Logistic regression classifiers based on peak intensities identified colorectal cancer with up to 78% sensitivity at 87% specificity. We identified and independently quantified 3 of the discriminatory peaks using synthetic stable isotope peptides (an 1885 Da fragment of fibrinogen and hepcidin-20) or ELISA (β2-microglobulin). Conclusion Changes in the urine proteome may aid in the early detection of colorectal cancer.

Abstract
Despite progression in anticancer drug development and improvements in the clinical utilization of therapies, current treatment regimes are still dependent upon the use of systemic antiproliferative cytotoxic agents. Although these agents are unquestionably potent, their efficacy is limited by toxicity towards 'normal' cells and a lack of tumour selective targeting, resulting in a therapeutic index which is modest at best. Consequently, the development of more tumour selective cancer treatments, with better discrimination between tumour and normal cells is unequivocally an important goal for cancer drug discovery. One such strategy is to exploit the tumour phenotype as a mechanism for tumour-selective delivery of potent therapeutics. An exciting approach in this area is to develop anticancer therapeutics as prodrugs, which are non-toxic until activated by enzymes localized specifically in the tumour. Enzymes suitable for tumour-activated prodrug development must have increased activity in the tumour relative to non-diseased tissue and an ability to activate the prodrug to its active form. One class of enzyme satisfying these criteria are the tumour endoproteases, particularly the serine- and metallo-proteases. These proteolytic enzymes are essential for tumour angiogenesis, invasion and metastasis, the major defining features of malignancy. This review describes the concept behind development of tumour-endoprotease activated prodrugs and discusses the various studies to date that have demonstrated the huge potential of this approach for improvement of cancer therapy.
