[PMID: 38177060 DOI: 10.1080/14767058.2023.2294701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 12/10/2023] [Indexed: 01/06/2024]
Abstract
OBJECTIVE This study aimed to analyze the effect of low-molecular-weight heparin (LMWH) on the decidualization of stromal cells in early pregnancy and explore the effect of LMWH on pregnancy outcomes. METHODS Recurrent spontaneous abortion (RSA) mouse model (CBA/J × DBA/2) and normal pregnant mouse model (CBA/J × BALB/c) were established. The female mice were checked for a mucus plug twice daily to identify a potential pregnancy. When a mucus plug was found, conception was considered to have occurred 12 h previously. The pregnant mice were divided randomly into a normal pregnancy control group, an RSA model group, and an RSA + LMWH experimental group (n = 10 mice in each group). Halfway through the 12th day of pregnancy, the embryonic loss of the mice was observed; a real-time quantitative polymerase chain reaction was used to detect the messenger ribonucleic acid (mRNA) expressions of prolactin (PRL) and insulin-like growth factor-binding protein 1 (IGFBP1) in the decidua of the mice. Additionally, the decidual tissues of patients with RSA and those of normal women in early pregnancy who required artificial abortion were collected and divided into an RSA group and a control group. Decidual stromal cells were isolated and cultured to compare cell proliferation between the two groups, and cellular migration and invasion were detected by membrane stromal cells. Western blotting was used to detect the protein expressions of proliferating cell nuclear antigen (PCNA), cyclin D1, matrix metalloproteinase- (MMP) 2, and MMP-7 in stromal cells treated with LMWH. RESULTS Compared with the RSA group, LMWH significantly reduced the pregnancy loss rate in the RSA mice (p < 0.05). Compared with the RSA group, the LMWH + RSA group had significantly higher expression levels of PRL and IGFBP1 mRNA (p < 0.01). LMWH promoted the proliferation, migration, and invasion of human decidual stromal cells; compared with the control group, the expression levels of MMP-2, MMP-7, cyclin D1, and PCNA proteins in the decidual stromal cells of the LMWH group increased (p < 0.05). CONCLUSIONS The use of LMWH can improve pregnancy outcomes by enhancing the proliferation and migration of stromal cells in early pregnancy and the decidualization of stromal cells.

[PMID: 35970483 DOI: 10.1016/j.actbio.2022.08.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 07/26/2022] [Accepted: 08/08/2022] [Indexed: 11/26/2022]
Abstract
Enzyme-manipulated hydrogelation based on self-assembly of small molecules is an attractive methodology for development of functional biomaterials. Upon the catalysis of enzymes, small-molecular precursors are converted into assemblable building blocks, which arrange into high-ordered nanofibers via non-covalent interactions at the molecular level, and further trap water to form hydrogels at the macroscopic level. Such approach has numerous advantages of region- and enantioselectivity, and mild reaction conditions for encapsulation of biomedications or cells that are fragile to environmental change. In addition to the common applications as drug reservoirs or cell scaffolds, the utilization of endogenous enzymes as stimuli to initiate self-assembly in the living cells and tissue is considered as an intelligent spatiotemporally controllable hydrogelation strategy for biomedical applications. The enzyme-instructed in situ self-assembly and hydrogelation can modulate the cell behavior, and even present therapeutic bioactivities, which provides a new perspective in the field of disease treatment. In this review, we categorize distinct enzymatic stimuli and elaborate substrate design, catalytic characteristics, and mechanisms of self-assembly and hydrogelation. The biomedical applications in drug delivery, tissue engineering, bioimaging, and in situ gelation-produced bioactivity are outlined. Advantages and limitations regarding the state-of-the-art enzyme-driven hydrogelation technologies and future perspectives are also discussed. STATEMENT OF SIGNIFICANCE: Hydrogel is a semi-solid soft material containing a large amount of water. Due to the features of adjustable flexibility, extremely porous architecture, and the high similarity of structure to natural extracellular matrices, the hydrogel has broad application prospects in biomedicine. In recent 20 years, enzyme-manipulated hydrogelation based on self-assembly of small molecules has developed rapidly as an attractive methodology for the construction of functional biomaterials. Upon the catalysis of enzymes, small-molecular precursors are converted into assemblable building blocks, which arrange into high-ordered nanofibers via non-covalent interactions at the molecular level, and further trap water to form hydrogels at the macroscopic level. This review summarized the characteristics of enzymatic hydrogel, as well as the traditional application and emerging prospect of enzyme-instructed self-assembly and hydrogelation.

Expression of Matrix Metalloproteinase-7 Predicts Poor Prognosis in Gastric Cancer. BIOMED RESEARCH INTERNATIONAL 2022; 2022:2300979. [PMID: 35496040 PMCID: PMC9054443 DOI: 10.1155/2022/2300979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Accepted: 03/31/2022] [Indexed: 11/17/2022]
Abstract
To date, no potential markers have been established for predicting prognosis in gastric cancer. Matrix metalloproteinase-7 (MMP-7) has been suggested as a prognostic marker in several cancers. In this study, we aimed to determine the expression of the MMP-7 protein and its polymorphisms in gastric cancer tissues. The association between MMP-7 expression level and clinicopathological characteristics was also evaluated. MMP-7 protein expression and its polymorphisms were investigated in a total of 400 patients using immunohistochemistry and TaqMan SNP genotyping assays. The correlation of MMP-7 expression with clinicopathological characteristics, including tumor location, tumor size, histologic type, lymphatic invasion, vascular invasion, pathological T stage, pathological TNM stage, residual tumor, and CEA level, was investigated. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a multivariate Cox proportional hazards regression model. MMP-7 expression was found in 283 of 400 (70.75%) gastric cancer tissues. Expression of MMP-7 was significantly associated with poor clinicopathological characteristics, including vascular invasion (

Targeting matrix metalloproteinase MMP3 greatly enhances oncolytic virus mediated tumor therapy. Transl Oncol 2021; 14:101221.

Abstract
In cancer, the extracellular matrix is extensively remodeled during chronic inflammation, thus affecting cell transcription, differentiation, migration and cell-cell interactions. Matrix metalloproteinases can degrade the extracellular matrix of tumor tissues and take important roles in disease progression. Numerous efforts to develop cancer treatments targeting matrix metalloproteinases have failed in clinical trials owing to the ineffectiveness and toxicity of the applied inhibitors. In this study, we investigated the potential of targeting matrix metalloproteinases and oncolytic virus combination in cancer therapy. We found that MMP3 expression was upregulated in various cancers and MMP3 expression in the tumor cells, but not in other tissues, was important for tumor growth and metastasis. Single treatment of colon cancer with multiple MMP3 inhibitors was not effective in mice. Nevertheless, the therapeutic effect of MMP3 was greatly improved by combination with an oncolytic virus. A potential mechanism of MMP3 in regulating tumor cell proliferation and invasion was mediated via Erk1/2 an NF-κB signaling. This study reveals that MMP3 is a promising target and the combined treatment with oncolytic virus is a potential strategy for cancer therapy.

Abstract
Acquisition of metastatic potential by cancer cells is related to cancer stemness and anchorage-independent growth. The onset and progression of cancer are known to involve Hedgehog (HH) signaling that is activated by the binding of HH to the Patched 1 (PTCH1) receptor. However, the functions and mechanisms of action of PTCH1 in the context of bone metastasis remain to be elucidated. In this study, lentivirally-delivered shRNA was used to deplete PTCH1 levels, which resulted in the inhibition of spherical colony formation by the human non-small cell lung cancer (NSCLC) cell line; this suggested that PTCH1 promotes anchorage-independent growth. Concordantly, knockdown of PTCH1 resulted in significantly reduced migration and invasion of NSCLC cells; this was accompanied by the downregulation of MMP7 and SOX2. PTCH1 knockdown resulted in decreased bone destruction and osteoclastogenesis in a mouse bone metastasis model. These results indicate that PTCH1 may be an important regulator of bone invasion, and strongly suggest that knockdown of PTCH1 may decrease the anchorage-independent growth and metastatic potential of NSCLC.

THE AMERICAN JOURNAL OF PATHOLOGY 2019; 189:1732-1743.

Abstract
Approximately 15% to 20% of colorectal cancers are developed through the serrated pathway of tumorigenesis, which is associated with BRAF mutation, CpG island methylation phenotype, and MLH1 methylation. However, the detailed process of progression from sessile serrated adenoma (SSA) to dysplasia and carcinoma has not been elucidated. To further characterize mechanisms involved in the dysplastic progression of SSA, we investigated differential expressions of mRNAs between areas with and without dysplasia within the same SSA polyps. Significantly dysregulated genes in paired samples were applied for functional annotation and biological significance. The same lysates from a subset of matched samples were subjected for miRNA expression profiling. Differentially expressed miRNAs were determined, and their targeted mRNAs were compared in parallel to the list of differentially expressed mRNAs from an RNA sequencing study. Fourteen common mRNA targets were identified, which include AXIN2, a known indicator of WNT/β-catenin pathway activation. Together, in this study, different genes, pathways, and biological processes involved in the initiation and progression of dysplasia in the serrated pathway are documented. One of the most significant findings is the involvement of the WNT/β-catenin pathway in the dysplastic progression of SSAs with different genes being targeted in early versus advanced dysplasia.

Farnesoid X receptor represses matrix metalloproteinase 7 expression, revealing this regulatory axis as a promising therapeutic target in colon cancer. J Biol Chem 2019; 294:8529-8542.

Abstract
The farnesoid X receptor (FXR) is a member of the nuclear receptor superfamily of bile acid-activated transcription factors and an important regulator of cell proliferation, apoptosis, and Wnt signaling. Down-regulated expression of FXR plays an important role in some malignancies such as colon cancer, and in rodent models of intestinal neoplasia, FXR knockout increases the size and number of colon tumors. These previous observations implicate FXR as a tumor suppressor, but the underlying molecular mechanisms are unclear. Employing complementary experimental approaches and using human colon cancer specimens, human and murine colon cancer cell lines, and FXR transgenic mice, here we identified an additional, potentially important role for FXR. We observed an inverse relationship between the expression of FXR and matrix metalloproteinase-7 (MMP7), a collagenase and signaling molecule consistently associated with colon cancer progression. We noted that FXR gene ablation increases MMP7 expression. Consistent with this finding, FXR overexpression and a dominant-negative FXR mutation reduced and augmented, respectively, MMP7 expression. Of note, MMP7 was the only MMP gene family member whose expression was down-regulated after FXR activation. FXR-mediated regulation of MMP7 transcription did not require heterodimerization with the retinoid X receptor (RXR), indicating that FXR represses MMP7 expression independently of RXR. Last, we uncovered that FXR suppresses MMP7 transcription by binding to a negative FXR-responsive element in the 5' MMP7 promoter, an event that inhibited colon cancer cell proliferation and invasion. These findings identify the FXR-MMP7 axis as a potential therapeutic target for managing colon cancer.

Abstract
BACKGROUND/AIM Matrix metalloproteinase 7 (MMP7) expression is highly associated with colorectal cancer and modulates tumour growth and invasion. Radiation injury induces inflammation with increases in MMP7 and in transforming growth factor beta (TGFβ). The aim of this study was to investigate the effect on MMP7 and TGFβ. expression in patients with rectal cancer undergoing different regimens of neoadjuvant radiotherapy (RT). PATIENTS AND METHODS We studied 53 patients in three RT treatment groups receiving RT of 25 Gy, long-term RT 50 Gy and controls receiving no RT. Three biopsies were obtained from each patient during the treatments: before RT, after RT and after surgery. Tissue samples were formalin fixed, paraffin embedded and tissue microarrays were constructed and stained for MMP7 and TGFβ. Mann-Whitney U-tests and Wilcoxon Z-tests were used to determine differences between patients before and after RT, and after surgery, as well as between the RT groups. RESULTS In all three patient groups, increases of MMP7 and TGFβ expression were observed after surgery. MMP7 expression was significantly increased in patients receiving short-term RT but TGFβ expression was not affected by RT. CONCLUSION 50 Gy Irradiation of rectal cancer gives less tumour activation of MMP7, whilst it is up-regulated by 25 Gy and surgery regardless of RT.

Abstract
Background The biological and clinical significance of matrix metalloproteinase-7 (MMP-7) in cervical cancer remains unknown. Here, we investigated the function of MMP-7 in cervical cancer cells and evaluated its clinical significance in both tissues and serum from cervical cancer patients. Methods First, we analyzed the expression of MMP-7 in cervical cancer using Oncomine microarray data and examined its expression in cervical tissues by quantitative real-time polymerase chain reaction and Western blotting. Second, we utilized gene silencing to explore the role of MMP-7 in cells. Finally, we examined the MMP-7 levels in patients with cervical cancer and normal serum by enzyme-linked immunosorbent assay. Moreover, we further investigated the relationship between MMP-7 expression and pathological features. Results The mRNA and protein MMP-7 levels were higher in cervical cancer tissues than in healthy controls. Silencing of MMP-7 significantly decreased cervical cancer cell proliferation, migration, and invasion. The serum MMP-7 levels were significantly higher in cervical cancer patients than in healthy subjects (P<0.01). Further, higher MMP-7 expression was associated with increased lymph metastasis (P=0.021), pathological grade (P=0.039, P=0.047), and clinical stage (P=0.049, P=0.046). Conclusion MMP-7 appears to act as an oncogene in cervical cancer cells and is involved in cell proliferation, migration, and invasion. MMP-7 expression was significantly higher in the tissue and serum of cervical cancer patients compared to healthy individuals and was correlated with increased pathalogical grade, clinical stage, and lymph metastasis. Therefore, our data provide novel evidence that MMP-7 may be a clinically relevant biomarker for cervical cancer.

Abstract
The hallmark of tumours is the ability of cancerous cells to promote vascular growth, to disseminate and invade to distant organs. The metastatic process is heavily influenced by the extracellular matrix (ECM) density and composition of the surrounding tumour microenvironment. These microenvironmental cues, which include hypoxia, also regulate the angiogenic processes within a tumour, facilitating the spread of cancer cells. We engineered compartmentalized biomimetic colorectal tumouroids with stromal surrounds that comprised a range of ECM densities, composition and stromal cell populations. Recapitulating tissue ECM composition and stromal cell composition enhanced cancer cell invasion. Manipulation of ECM density was associated with an altered migration pattern from glandular buds (cellular aggregates) to epithelial cell sheets. Laminin appeared to be a critical component in regulating endothelial cell morphology and vascular network formation. Interestingly, the disruption of vascular networks by cancer cells was driven by changes in expression of several anti-angiogenic genes. Cancer cells cultured in our biomimetic tumouroids exhibited intratumoural heterogeneity that was associated with increased tumour invasion into the stroma. These findings demonstrate that our 3D in vitro tumour model exhibits biomimetic attributes that may permit their use in studying microenvironment clues of tumour progression and angiogenesis.

Abstract
The objective of the study is to investigate the CXCR5 and MMP-13 expression in colorectal cancer and explore its correlation between the clinicopathological characteristics and prognosis. The expressions of CXCR5 and MMP-13 proteins in 236 paired specimens of colorectal cancer and incisal edge normal tissues as well as 62 samples of colorectal adenoma tissues were analyzed by immunohistochemistry. The CXCR5 and MMP-13 positive expression rate in colorectal cancer tissues was 43.6 and 80.5 %, respectively. Both rates were higher than those in the incisal edge healthy intestinal mucosal tissues (4.2 and 13.1 %) and colorectal adenoma tissues (24.2 and 64.5 %), P < 0. 05 in both cases. The expressions of the CXCR5 and MMP-13 proteins were positively related to the lymph node and distal metastasis, tumor stage and relapse, P < 0. 05. The expression of the CXCR5 protein was positively related to MMP-13, P < 0. 05. The median and overall survival in the patients with positive CXCR5 and MMP-13 expression were significantly shorter than those with negative expression: median survival, 20.5 months (CXCR5 +) versus 30.8 months (CXCR5 -), 20.3 months (MMP-13 +) versus 24.6 months; overall survival, 26.5 months (CXCR5 +) versus 47.5 months (CXCR5 -), 22.7 months (MMP-13 +) versus 29.3 months. The expression of CXCR5 and MMP-13 could promote the pathogenesis, development, metastasis, and relapse of colorectal cancer. It could also serve as a valuable indicator for the prediction of metastasis and relapse of colorectal cancer.

Interstitial fluid flow and associated shear stress are relevant mechanical signals in cartilage and bone (patho)physiology. However, their effects on chondrosarcoma cell motility, invasion and metastasis have yet to be delineated. Using human SW1353, HS.819.T and CH2879 chondrosarcoma cell lines as model systems, we found that fluid shear stress induces the accumulation of cyclic AMP (cAMP) and interleukin-1β (IL-1β), which in turn markedly enhance chondrosarcoma cell motility and invasion via the induction of matrix metalloproteinase-7 (MMP-7). Specifically, shear-induced cAMP and IL-1β activate PI3-K, ERK1/2 and p38 signaling pathways, which lead to the synthesis of MMP-7 via transactivating NF-κB and c-Jun in human chondrosarcoma cells. Importantly, MMP-7 upregulation in response to shear stress exposure has the ability to promote lung colonization of chondrosarcomas in vivo. These findings offer a better understanding of the mechanisms underlying MMP-7 activation in shear-stimulated chondrosarcoma cells, and provide insights on designing new therapeutic strategies to interfere with chondrosarcoma invasion and metastasis.

Abstract
During the process of metastasis, which is the leading cause of cancer-related death, cancer cells dissociate from primary tumors, migrate to distal sites, and finally colonize, eventually leading to the formation of metastatic tumors. The migrating tumor cells in circulation, e.g., those found in peripheral blood (PB) or bone marrow (BM), are called circulating tumor cells (CTCs). CTCs in the BM are generally called disseminated tumor cells (DTCs). Many studies have reported the detection and characterization of CTCs to facilitate early diagnosis of relapse or metastasis and improve early detection and appropriate treatment decisions. Initially, epithelial markers, such as EpCAM and cytokeratins (CKs), identified using immunocytochemistry or reverse transcription polymerase chain reaction (RT-PCR) were used to identify CTCs in PB or BM. Recently, however, other markers such as human epidermal growth factor receptor 2 (HER2), estrogen receptor (ER), and immuno-checkpoint genes also have been examined to facilitate detection of CTCs with metastatic potential. Moreover, the epithelial-to-mesenchymal transition (EMT) and cancer stem cells (CSCs) have also received increasing attention as important CTC markers owing to their roles in the biological progression of metastasis. In addition to these markers, researchers have attempted to develop detection or capture techniques for CTCs. Notably, however, the establishment of metastasis requires cancer-host interactions. Markers from host cells, such as macrophages, mesenchymal stem cells, and bone marrow-derived cells, which constitute the premetastatic niche, may become novel biomarkers for predicting relapse or metastasis or monitoring the effects of treatment. Biological studies of CTCs are still emerging. However, recent technical innovations, such as next-generation sequencing, are being used more commonly and could help to clarify the mechanism of metastasis. Additionally, biological findings are gradually being accumulated, adding to our body of knowledge on CTCs. In this review, we will summarize recent approaches to detect or capture CTCs. Moreover, we will introduce recent studies of the clinical and biological importance of CTCs and host cells.

Abstract
We assessed herein the post-operative lymph node metastasis in head and neck cancer, using the One-step nucleotide amplification (OSNA) method targeting matrix metalloproteinase 7 (MMP-7). Compared with the pathological test, the molecular biological test revealed more lymph node metastasis, resulting in poor prognosis. Six cases, of which the number of lymph node metastasis was the same between pathological and molecular biological test, survived. On the other hand, three of four cases, in which number of lymph node metastasis in the molecular biological test were larger than the pathological test, died from metastasis. We concluded that the pathological test underestimated metastasis, and OSNA with MMP-7 was useful for the prediction of post-operative lymph node metastasis.

Abstract
Background Although matrix metalloproteinase (MMP)-7 expression is correlated with increased metastatic potential in human colon cancer cells, the underlying molecular mechanism of invasive phenotype remains unknown. In the current study, we investigated the regulatory effects of membrane NADPH oxidase (NOX) and AMP activated protein kinase (AMPK) on MMP-7 expression and invasive phenotype change in colon cancer cells. Methods Production of superoxide anion was measured by lucigenin chemiluminescence assay using whole cells and protein extracts (NADPH oxidase activity), and intracellular reactive oxygen species (ROS) by fluorescence microscopy using 2’,7’-dichlorofluorescein diacetate (DCF-DA). Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting were used to measure mRNA and protein levels, respectively. siRNA transfection was used to assess involvement of genes in cancer invasion, which were identified by Matrigel transwell invasion assay. Luciferase reporter assay was performed to identify transcription factors linked to gene expression. Results Under basal conditions, less invasive human colon cancer cells (HT29 and Caco-2) showed low MMP-7 expression but high NOX1 expression and AMPK phosphorylation. Treatment of HT29 and Caco-2 cells with 12-O-tetradecanoylphorbol-13-acetate (TPA) induced an invasive phenotype response along with corresponding increases in ROS production and NOX2 and MMP-7 expression as well as reduced AMPK phosphorylation, which resemble basal conditions of highly invasive human colon cancer cells (SW620 and HCT116). In addition, inverse regulation between AMPK phosphorylation and NOX2 and MMP-7 expression was observed in HT29 cells treated with different concentrations of exogenous hydrogen peroxide. TPA-induced invasive phenotype in HT29 cells was abolished by treatment with Vit. E, DPI, apocynin, and NOX2 siRNA but not NOX1 siRNA, indicating NOX2-derived ROS production induced an invasive phenotype. TPA-induced induction of MMP-7 expression was suppressed by AP-1, NF-κB, and MAPK (ERK, p38, and JNK) inhibitors, whereas TPA-induced expression of NOX2 and its regulators, p47phox and p67phox, was blocked by p38 and NF-κB inhibitors. Conclusions Molecular switch from NOX1 to NOX2 in colon cancer cells induces ROS production and subsequently enhances MMP-7 expression by deactivating AMPK, which otherwise inhibits stimulus-induced autoregulation of ROS and NOX2 gene expression.

Abstract
Plakophilin3 (PKP3) loss results in increased transformation in multiple cell lines in vitro and increased tumor formation in vivo. A microarray analysis performed in the PKP3 knockdown clones, identified an inflammation associated gene signature in cell lines derived from stratified epithelia as opposed to cell lines derived from simple epithelia. However, in contrast to the inflammation associated gene signature, the expression of MMP7 was increased upon PKP3 knockdown in all the cell lines tested. Using vector driven RNA interference, it was demonstrated that MMP7 was required for in-vitro cell migration and invasion and tumor formation in vivo. The increase in MMP7 levels was due to the increase in levels of the Phosphatase of Regenerating Liver3 (PRL3), which is observed upon PKP3 loss. The results suggest that MMP7 over-expression may be one of the mechanisms by which PKP3 loss leads to increased cell invasion and tumor formation.

Abstract
Epithelial to mesenchymal transition (EMT) is an integral process in the progression of many epithelial tumors. It involves a coordinated series of events, leading to the loss of epithelial features and the acquisition of a mesenchymal phenotype, resulting in invasion and metastasis. The EMT of hepatocellular carcinoma (HCC) cells is thought to be a key event in intrahepatic dissemination and distal metastasis. In this study, we used 12-O-tet-radecanoylphorbol-13-acetate (TPA) to dissect the signaling pathways involved in the EMT of HepG2 hepatocarcinoma cells. The spectacular change in phenotype induced by TPA, leading to a pronounced spindle-shaped fibroblast-like cell morphology, required ERK1/2 activation. This ERK1/2-dependent EMT process was characterized by a loss of E-cadherin function, modification of the cytoskeleton, the acquisition of mesenchymal markers and profound changes to extracellular matrix composition and mobility. Snail was essential for E-cadherin repression, but was not sufficient for full commitment of the TPA-triggered EMT. We found that TPA triggered the formation of a complex between Snail and β-catenin that activated the Wnt pathway. This study thus provides the first evidence for the existence of a complex network governed by the ERK1/2 signaling pathway, converging on the coregulation of Snail and the Wnt/β-catenin pathway and responsible for the onset and the progression of EMT in hepatocellular carcinoma cells.

Abstract
Metastatic potential of prostate cancer is thought to correlate with the degradation of basement membrane components by matrix metalloproteinases (MMPs). The MMP-7 (matrilysin) gene is overexpressed in prostate cancer as well as colorectum and brain cancer. In order to clarify the relation of MMP-7 to clinical stages of prostate cancer, recombinant human MMP-7 was produced to prepare antibodies for immunohistochemistry and immunoassay. Preproform of human MMP-7 was produced in Escherichia coli as inclusion bodies that could be solubilized and refolded to yield an activatable proenzyme. PreproMMP-7 (Mr 31,000) solubilized from inclusion bodies was converted to proMMP-7 (Mr 30,000) during the refolding steps. The refolded proMMP-7 was purified to about 80% homogeneity as MMP-7 by sequential ion-exchange and molecular-sieve chromatography. The active, mature form of MMP-7 (Mr 20,000) could be produced from proforms of MMP-7 by treatment with p-aminophenylmercuric acetate. Activated MMP-7 was shown to have proteolytic activity to fibronectin, casein, and diazotized, denatured collagen (Azocoll). Specific activity, as assayed with the denatured collagen as substrate, was measured to be about 3,100 units/mg protein of mature enzyme. Using recombinant proMMP-7 as antigen, monoclonal and polyclonal antibodies were prepared. A sandwich ELISA was developed using monoclonal antibody as the capture antibody and rabbit anti-proMMP-7 polyclonal IgG conjugated with biotin as the detection antibody; MMP-7 at 10 ng/ml was significantly detectable. The assay system is applicable on the measurement of MMP-7 levels in the clinical and pathologic specimens including serum from patients with different stages in malignancy of prostate cancer. These antibodies are useful for the retrospective analyses of prostate cancer on the basis of immunohistochemical evaluation.

Stable differences in intrinsic mitochondrial membrane potential of tumor cell subpopulations reflect phenotypic heterogeneity. Int J Cell Biol 2011; 2011:978583.

Abstract
Heterogeneity among cells that constitute a solid tumor is important in determining disease progression. Our previous work established that, within a population of metastatic colonic tumor cells, there are minor subpopulations of cells with stable differences in their intrinsic mitochondrial membrane potential (ΔΨm), and that these differences in ΔΨm are linked to tumorigenic phenotype. Here we expanded this work to investigate primary mammary, as well as colonic, tumor cell lines. We show that within a primary mammary tumor cell population, and in both primary and metastatic colonic tumor cell populations, there are subpopulations of cells with significant stable variations in intrinsic ΔΨm. In each of these 3 tumor cell populations, cells with relatively higher intrinsic ΔΨm exhibit phenotypic properties consistent with promotion of tumor cell survival and expansion. However, additional properties associated with invasive potential appear in cells with higher intrinsic ΔΨm only from the metastatic colonic tumor cell line. Thus, it is likely that differences in the intrinsic ΔΨm among cells that constitute primary mammary tumor populations, as well as primary and metastatic colonic tumor populations, are markers of an acquired tumor phenotype which, within the context of the tumor, influence the probability that particular cells will contribute to disease progression.

Abstract
Esophagus squamous cell carcinoma (ESCC) is one of the most deadly malignances because of its high frequency of metastasis. Given the associations of MUC1 with ESCC and tumor metastasis, we explored a potential role of MUC1 in ESCC metastasis. Among 40 ESCC and 20 paired normal tissue specimens examined, we found a significant increase of MUC1 expression in ESCC and more importantly, that expression of MUC1 and MMP13 are strongly correlated in patients who had lymph node metastasis. Studies with cell models indicated that overexpression of MUC1 upregulates the expression of MMP13, leading to increased cell migration. In support of a mode of transcriptional regulation, promoter analysis revealed that MUC1 stimulates MMP13 expression through the Runx-2-binding site. The link of MUC1 to cell motility was further confirmed by the finding that depletion of MUC1 resulted in reduced expression of MMP13 and cell migration, invasion and adhesion. Moreover, the loss of cell metastatic potential was rescued by overexpression of MMP13 completely. Collectively, our findings indicate that MUC1 contributes to ESCC metastasis by stimulating MMP13 expression, suggesting MUC1 as a novel diagnostic biomarker and therapeutic target in ESCC.

Abstract
BACKGROUND The current study was conducted to demonstrate the utility of a multiplexed, particle-based flow cytometric assay for the simultaneous analysis of a panel of matrix metalloproteinases (MMPs) using small volumes of plasma samples from patients with bladder cancer. In addition, the authors attempted to test the hypothesis that plasma levels of MMPs are associated with time to cancer-related death. METHODS Plasma MMP concentrations (MMP-1, -2, -3, -7, -8, -9, and -12) in 135 patients presenting with high-grade≥T1 bladder cancer were measured. Data regarding clinical and pathologic features was ascertained in a retrospective fashion. RESULTS The median duration of follow-up was 30.4 months. At the time of analysis, 61 patients had died, including 45 (33.3%) who died of bladder cancer. Plasma MMP-12 was not measurable. For all other MMPs, the intra-assay coefficient of variation varied from 6.12% to 9.82%. MMP-1, -2, -3, -8, and -9 were not found to be significantly associated with time to cancer-related death. Plasma MMP-7 levels were significantly associated with time to cancer-related death after adjustment for competing clinical and pathologic features (hazard ratio [HR], 2.2; 95% confidence interval [95% CI], 1.1-4.5 [P=.022]). The 5-year median cancer-specific survival rates for those patients with MMP-7 levels above and below the median value (300 pg/mL) were 73.6% (95% CI, 60.0-83.2%) and 48.0% (95% CI, 32.5-61.9%), respectively (P=.01). CONCLUSIONS Multiplexed, particle-based flow cytometric assay allows for the high-throughput measurement of multiple plasma or serum proteins simultaneously. By using this new technology in a cohort of patients with bladder cancer, plasma levels of MMP-7 were identified as being significantly associated with time to cancer-related death.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are involved in the degradation of extracellular matrix components and are associated with invasion and metastasis. MMP proteins could be serum tumor markers or molecular targets in the treatment of malignancy. The purpose of the current study was to identify a prognostic serum marker in cases of colorectal cancer (CRC) prior to surgical intervention. MATERIALS AND METHODS Laser microdissection and microarray analysis were used to characterize gene expression in 73 cases of CRC. We then focused on expression of MMP-1. We examined serum MMP-1 activity before resection in another subset of 75 cases of CRC to validate the clinical significance of MMP-1 as a prognostic marker in CRC after surgically curative operation. RESULTS Disease-free survival was 51% in the MMP-1 high expression group and 81% in the low-expression group (P < .05). Survival was 52% in the MMP-1 high expression group and 90% in the low group (P < .05). In multivariate analysis for disease-free survival, MMP-1 and lymph node metastasis were significant independent prognostic indicators. In multivariate analysis of overall survival, serum MMP-1 level was the only significant independent indicator among factors. CONCLUSIONS Within the MMP family of proteins, MMP-1 is not a cancer-specific protease. However, MMP-1 activity does predict the future course of progression of malignant cells. Thus, MMP-1, which is activated at the primary lesion and is found in serum, assists in the clinical diagnosis of CRC. It is also an important molecule for understanding the underlying mechanism of invasion and metastasis of CRC.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection up-regulates the expression of matrix metalloproteinases (MMPs), which may be involved in chronic inflammation, ulceration, and even cancer development. This study aimed to test if serum levels of MMP-3, -7, and -9 are correlated with different clinical outcomes in H. pylori-infected subjects and if these are predictive of progression to H. pylori-related gastric cancer. METHOD Two hundred one patients, 28 with H. pylori-negative gastritis and 173 with different H. pylori-positive gastrointestinal diseases (46 gastritis, 43 duodenal ulcers, 29 gastric ulcers, and 55 gastric cancers) were assessed for serum MMP-3, -7, and -9 titers by enzyme-linked immunosorbent assay and validated to their correlations with the different clinical features and survival of patients with H. pylori-positive gastric cancer. RESULTS Among the H. pylori-infected subjects, gastric cancer patients had higher serum levels of MMP-3 and MMP-7 than those with duodenal ulcer and gastritis (P < 0.05). For gastric cancer patients, concomitant elevated MMP-3 (>14 ng/ml) and MMP-7 (>4.5 ng/ml) independently correlated with lymph node invasion (P < 0.05) and could be predictive to have shorter 2- or 5-year survivals (log rank test, P = 0.006). CONCLUSION Concomitant elevations of MMP-3 and MMP-7 serum levels in the H. pylori-infected gastric cancer patients could serve as potential biomarkers to correlate with poor survival.

Abstract
The traditional Chinese medicine, Hong-Qu, also called red mold rice in the United States and Europe, is used for treating blood stasis, a disorder related to hyperlipidemia and atherosclerosis. In addition to improving metabolic syndrome, extracts from Monascus-fermented rice inhibit the proliferation of various cancer cells in vitro and in vivo. The objective was to examine the effect of red mold rice ethanol extract (RMRE) on angiogenesis, invasion, and metastasis during tumor progression. RMRE significantly inhibited the proliferation of SW480 and SW620 human colorectal carcinoma cells in a dose- and time-dependent manner by using the MTT assay. A capillary-like network morphology was observed after the addition of 20 ng/mL vascular endothelial growth factor or SW620 culture-conditional medium, which was not seen after RMRE treatment. Moreover, spontaneous intravasation into Matrigel grafts of SW620 cells from the upper to the lower layers in the chick embryo chorioallantoic membrane (CAM) model was detected by the polymerase chain reaction (PCR) amplification of human Alu genomic DNA from the lower CAMs in the RMRE-untreated group. Neovascularization increased to 75.3% +/- 11.6% by SW620 cells onplant with Matrigel grafts in the CAM model. However, RMRE significantly reduced CAM neovascularization in a dose-dependent manner. Finally, RMRE effectively decreased the activity of matrix metalloproteinase (MMP)-7 as determined by reverse transcription PCR (RT-PCR), Western blotting, and casein zymography assays. In summary, Monascus-fermented products exert a potent effect on tumor growth and activation, suggesting that they may serve as supplementary agents in adjuvant cancer therapy.

Abstract
Cancer is well known to be associated with alterations in membrane protein glycosylation (Bird, N. C., Mangnall, D., and Majeed, A. W. (2006) Biology of colorectal liver metastases: A review. J. Surg. Oncol. 94, 68-80; Dimitroff, C. J., Pera, P., Dall'Olio, F., Matta, K. L., Chandrasekaran, E. V., Lau, J. T., and Bernacki, R. J. (1999) Cell surface n-acetylneuraminic acid alpha2,3-galactoside-dependent intercellular adhesion of human colon cancer cells. Biochem. Biophys. Res. Commun. 256, 631-636; and Arcinas, A., Yen, T. Y., Kebebew, E., and Macher, B. A. (2009) Cell surface and secreted protein profiles of human thyroid cancer cell lines reveal distinct glycoprotein patterns. J. Proteome Res. 8, 3958-3968). Equally, it has been well established that tumor-associated inflammation through the release of pro-inflammatory cytokines is a common cause of reduced hepatic drug metabolism and increased toxicity in advanced cancer patients being treated with cytotoxic chemotherapies. However, little is known about the impact of bearing a tumor (and downstream effects like inflammation) on liver membrane protein glycosylation. In this study, proteomic and glycomic analyses were used in combination to determine whether liver membrane protein glycosylation was affected in mice bearing the Engelbreth-Holm Swarm sarcoma. Peptide IPG-IEF and label-free quantitation determined that many enzymes involved in the protein glycosylation pathway specifically; mannosidases (Man1a-I, Man1b-I and Man2a-I), mannoside N-acetylglucosaminyltransferases (Mgat-I and Mgat-II), galactosyltransferases (B3GalT-VII, B4GalT-I, B4GalT-III, C1GalT-I, C1GalT-II, and GalNT-I), and sialyltransferases (ST3Gal-I, ST6Gal-I, and ST6GalNAc-VI) were up-regulated in all livers of tumor-bearing mice (n = 3) compared with nontumor bearing controls (n = 3). In addition, many cell surface lectins: Sialoadhesin-1 (Siglec-1), C-type lectin family 4f (Kupffer cell receptor), and Galactose-binding lectin 9 (Galectin-9) were determined to be up-regulated in the liver of tumor-bearing compared with control mice. Global glycan analysis identified seven N-glycans and two O-glycans that had changed on the liver membrane proteins derived from tumor-bearing mice. Interestingly, α (2,3) sialic acid was found to be up-regulated on the liver membrane of tumor-bearing mice, which reflected the increased expression of its associated sialyltransferase and lectin receptor (siglec-1). The overall increased sialylation on the liver membrane of Engelbreth-Holm Swarm bearing mice correlates with the increased expression of their associated glycosyltransferases and suggests that glycosylation of proteins in the liver plays a role in tumor-induced liver inflammation.

Abstract
INTRODUCTION Hyaluronan (HA) and its biosynthetic enzymes hyaluronan synthases (HAS2 and HAS3) mediate Matrigel invasion by SW620 colon carcinoma cells. Because matrix metalloproteinases (MMPs) have been implicated in cancer invasion, we hypothesized that changes in HAS expression would alter MMP expression and activity in these cells. METHODS To determine whether an MMP was involved in invasion, Matrigel invasion assays with SW620 cells were performed in the presence or absence of the MMP inhibitors GM6001 or TIMP2. HAS isozymes were inhibited by stably transfecting SW620 cells with vectors that contained antisense HAS2 and/or -3 cDNA; transfection with an empty vector served as a control. MMP-7 transcription was assessed by quantitative reverse transcription polymerase chain reaction (RT-PCR). MMP-7 protein was detected by enzyme-linked immunosorbent assay (ELISA) and enzymatic activity compared using zymography. RESULTS GM6001 and TIMP2 decreased Matrigel invasion, which confirms that an MMP played a key role in this process. MMP-7 expression was then detected in SW620 cells. Finally, MMP-7 expression, protein, and enzymatic activity were significantly lower in antisense HAS tranfectants than in SW620 or vector control cells. CONCLUSION We have demonstrated previously that inhibition of HAS expression and HA production in SW620 colon carcinoma cells inhibits Matrigel invasion. In the studies presented here, we have demonstrated that SW620 cells express high levels of MMP-7 and that inhibition of HAS isozymes dramatically decreases MMP-7 expression, protein, and enzymatic activity. Taken together, these findings suggest that HAS and HA may mediate cellular invasion via changes in MMP-7 expression.

Abstract
Matrix metalloproteinase-7 (MMP-7) is a small secreted proteolytic enzyme with broad substrate specificity. Its expression has been shown to be associated with tumor invasion, metastasis and survival for a variety of cancers. We systematically evaluated single nucleotide polymorphisms (SNPs) in MMP-7 in relation to breast cancer survival in a large follow-up study. Included were 1,079 breast cancer cases that were recruited from 1996 to 1998 and followed for a median of 7.1 years as part of the Shanghai Breast Cancer Study (SBCS). Eleven SNPs, including 2 known functional promoter SNPs, were analyzed using the Affymetrix Targeted Genotyping System. Associations with survival were evaluated by Cox proportional hazards regression and Kaplan-Meier functions. Statistically significant associations with disease-free and/or overall survival (OS) were found for 5 polymorphisms; these associations were explained primarily by 2 SNPs (rs11568818 and rs11225297) that were in high linkage disequilibrium (LD) with the others. Patients homozygous for the rs11568818 rare allele (G) had a significantly worse prognosis (OS HR: 6.7, 95% CI: 2.4-18.6) than patients homozygous for the common allele (A). Significantly improved survival was seen for patients with the rs11225297 T allele, and this association occurred in a dose-response manner; patients with AT (OS HR: 0.7, 95% CI: 0.5-0.9) and TT (OS HR: 0.3, 95% CI: 0.1-0.8) fared better than patients with AA (p-value for trend: 0.001). Thus, common MMP-7 genetic polymorphisms were found to be significant determinants of survival among Chinese women with breast cancer.

Abstract
BACKGROUND The fragile histidine triad (FHIT) functions as a tumor suppressor, and giving adenoviral-FHIT (Ad-FHIT) is thus expected to be clinically beneficial. Much attention has recently been focused on which genes are commonly regulated by Ad-FHIT, and which genes are dominant in Ad-FHIT-induced apoptotic cells. METHODS Ad-FHIT apoptosis-induced cells (H1299 and TE4) and non-apoptosis-induced cells (TE2) were used in the current experiments. The total RNA extracted from Ad-FHIT or control was labeled with Cy3-dCTP or Cy5-dCTP and hybridized with 19,192 genes on a chip. A microarray analysis for each gene was carried out with high reproducibility provided by seven independent experiments and duplicated oligos on a chip. RESULTS We listed the upregulated genes based on the TE4:TE2 expression ratio, such as c-Src, Jak-1, and sialyltransferase, which are expected to be target pathways as well as the downregulated genes, including CASP8 and CASP10, after Ad-FHIT treatment in esophageal cancer. CONCLUSIONS The current microarray analysis indicated that the apoptosis of esophageal cancer observed after giving Ad-FHIT was possibly induced by activation of the c-Src gene and inactivation of the CASP8 gene.

Abstract
Matrix metalloproteinase-7 (MMP-7) is a small secreted proteolytic enzyme with broad substrate specificity against ECM and non-ECM components. Known to be vital for tumor invasion and metastasis, accumulating evidence also implicates MMP-7 in cancer development. Using data from the Shanghai Breast Cancer Study, we conducted a two-stage study to evaluate the association of MMP-7 single nucleotide polymorphisms (SNPs) with breast cancer risk. Additionally, associated SNPs were characterized by laboratory assays. In stage 1, 11 SNPs were genotyped among 1,079 incident cases and 1,082 community controls using an Affymetrix Genotyping System. Promising SNPs were selected for stage 2 evaluation and genotyped by TaqMan allelic discrimination assays in an independent set of 1,911 cases and 1,811 controls. Three SNPs were selected for stage 2 validation (rs880197, rs10895304, and rs12184413); one had highly consistent results between the two stages of the study. In combined analysis, homozygosity for the variant T allele for rs12184413 was associated with an odds ratio (OR) of 0.7 [95% confidence interval (95% CI), 0.6-0.9] compared with the common C allele. This effect was slightly more pronounced in postmenopausal women (OR, 0.6; 95% CI, 0.4-0.8) than in premenopausal women (OR, 0.8; 95% CI, 0.6-1.1). This SNP is located 3' of the MMP-7 gene, in an area enriched with CTCF binding sites. In silico analysis suggested a regulatory role for this region, and our in vitro assays showed an allelic difference in nuclear protein binding capacity. Results from our study suggest that common MMP-7 genetic polymorphisms may contribute to breast cancer susceptibility.

Abstract
Highly metastatic ras/myc-transformed serum-free mouse embryo (r/m HM-SFME-1) cells were injected subcutaneously to mice and the effects of Nomega-nitro-L-arginine methyl ester (L-NAME) on the tumor progression and pulmonary metastasis were investigated. In addition, production of nitric oxide (NO), matrix metalloproteinases (MMPs) and tumor necrosis factor-alpha (TNF-alpha) in the tumor cells and in a mouse macrophage-like cell line, J774.1 cells, was analyzed. The increase in footpad thickness was significantly smaller in the mice which were fed the L-NAME containing water (4.24+/-0.39 mg/day/mouse). The number of the tumor cells metastasized to the lungs was smaller in the L-NAME treated mice, although statistical significance was not found. Co-treatment of r/m HM-SFME-1 cells with interferon-gamma (IFN-gamma; 100 U/ml) and lipopolysaccharide (LPS; 0.5 microg/ml) significantly enhanced NO production, and the presence of L-NAME at 1 mM significantly decreased this response. In r/m HM-SFME-1 cells, MMP-2 was undetectable and MMP-9 was also very little in the basal level, and both MMPs were unaffected by the IFN-gamma and/or LPS treatments, not to mention by the L-NAME treatment. In J774.1 cells, any treatment including LPS appeared to enhance MMP-9 production, however, this upregulation was not inhibited by the additional presence of L-NAME. Production of TNF-alpha by J774.1 cells was markedly enhanced with LPS treatment, and this enhancement was significantly reduced in the presence of L-NAME. These results indicate that the inhibitory effects of L-NAME on the tumor cell progression and pulmonary metastasis could be due to suppression of NO from tumor cells and TNF-alpha from macrophages (Mol Cell Biochem, 2007).

Abstract
Inflammatory and infectious conditions were simulated in cultures of ras/myc-transformed serum-free mouse embryo (ras/myc SFME) cells, using interferon-gamma (IFN-gamma, 100 units/ml) and lipopolysaccharide (LPS, 0.5 microg/ml) co-treatment for 24 h, to investigate their effects on the expression of inducible nitric oxide synthase (iNOS) mRNA and the production of NO. Aminoguanidine (AG, 1 mM; an NOS inhibitor) along with IFN-gamma and LPS, S-nitroso-N-acetyl-DL-penicillamine (SNAP, 100 microM; an NO donor) and/or (+/-)-N-[(E)-4-Ethyl-2-[(Z)-hydroxyimino]-5-nitro-3-hexene-1-yl]-3-pyridine carboxamide (NOR4, 100 microM; an NO donor), were also added to analyze the possible association of NO with matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1). Co-treatment of cells with IFN-gamma and LPS increased iNOS mRNA expression, NO production, MMP-9 mRNA expression, and 105 kDa MMP-9 production. Additional treatment with the NOS inhibitor AG inhibited NO production, but did not down-regulate the expression of MMP-9 mRNA or 105 kDa MMP-9. The NO donors SNAP and NOR4 did not affect the expression of MMP-9 mRNA, 105 kDa MMP-9 or TIMP-1 mRNA. These results suggest that ras/myc SFME cells respond to infectious and inflammatory conditions and can enhance malignancy as cancer cells due to their increased levels of NO and MMP-9 production, but that NO is not directly associated with MMP-9 in these cells.

Abstract
BACKGROUND AND AIM Characteristic clinicopathological features of laterally spreading tumors (LSTs) have been reported by endoscopists; however, only a few studies have been conducted on the biological features. These studies were not fully associated with the endoscopic findings of LSTs. The aim of this study was to estimate the biological features of each type of endoscopic finding of LST using two molecular markers, matrix metalloproteinase-7 (MMP-7) and beta-catenin. METHODS Expression of the molecular markers and the endoscopic findings were compared in 22 LSTs and 14 subpedunculated polyps. MMP-7 and beta-catenin were immunostained. Three types of representative endoscopic findings of LST were defined as segments in LSTs. They were 15 granular segments, seven large nodular segments, and seven flat segments that corresponded to the area composed of aggregates of similar size granules, large nodules of diameter more than 10 mm, and a flat surface with no granule, respectively. RESULTS Expression of MMP-7 and coexpression of MMP-7 and beta-catenin were higher in large nodular segments than in granular segments (P < 0.0167). Among the three types of segments, flat segments showed the highest expression densities of beta-catenin accumulated in the nucleus. Large nodular segments and subpedunculated polyps showed similar expression patterns for the molecular markers. CONCLUSIONS This study provides new and important information on the relationship between the molecular markers and endoscopic findings of LSTs.

Abstract
Background Matrix metalloproteinases (MMP) have been shown to play a role in colorectal cancer (CRC). More recently, MMP1, MMP3 and MMP7 functional gene promoter polymorphisms have been found to be associated with CRC occurrence and prognosis. To document the role of MMP polymorphisms in the early step of colorectal carcinogenesis, we investigated their association with colorectal adenoma risk in a case-control study comprising 295 patients with large adenomas (LA), 302 patients with small adenomas (SA) and 568 polyp-free (PF) controls. Methods Patients were genotyped using automated fragment analysis for MMP1 -1607 ins/del G and MMP3 -1612 ins/delA (MMP3.1) polymorphisms and allelic discrimination assay for MMP3 -709 A/G (MMP3.2) and MMP7 -181 A/G polymorphisms. Association between MMP genotypes and colorectal adenomas was first tested for each polymorphism separately and then for combined genotypes using the combination test. Adjustment on relevant variables and estimation of odds ratios were performed using unconditional logistic regression. Results No association was observed between the polymorphisms and LA when compared to PF or SA. When comparing SA to PF controls, analysis revealed a significant association between MMP3 -1612 ins/delA polymorphism and SA with an increased risk associated with the 6A/6A genotype (OR = 1.67, 95%CI: 1.20–2.34). Using the combination test, the best association was found for MMP3.1-MMP1 (p = 0.001) with an OR of 1.88 (95%CI: 1.08–3.28) for the combined genotype 2G/2G-6A/6A estimated by logistic regression. Conclusion These data show a relation between MMP1 -1607 ins/del G and MMP3 -1612 ins/delA combined polymorphisms and risk of SA, suggesting their potential role in the early steps of colorectal carcinogenesis.

Abstract
PURPOSE The matrix metalloproteinases (MMPs) are a family of proteolytic enzymes. MMPs are known to be involved in tumor invasion, and several have been implicated in tumor prognosis. The aim of this study was to evaluate the prognostic significances of the expressions of MMP-7 and -9 in rectal cancer. MATERIALS AND METHODS The tumor tissues of 87 patients with stage II or III rectal carcinoma that underwent potentially curative resection followed by postoperative adjuvant chemoradiation and 5-fluorouracil based chemotherapy, were investigated immunohistochemically using monoclonal antibodies against MMP-7 and MMP-9. Clinical information, including tumor grades, carcinoembryonic antigen (CEA) levels, and disease-free survival and overall survival were evaluated with respect to the expressions of MMP-7 and -9. RESULTS Median follow-up duration was 53.2 months, and median patient age was 55±11 years (range 32~75). MMP-7 expression in tumor tissue was found to be significantly correlated with the presence of nodal metastasis (p=0.029), whilst MMP-9 expression correlated with depth of tumor invasion (p=0.019). No relationships were found between the expressions of MMP-7 or -9 and age, sex, tumor size, tumor grade, or CEA level. Univariate analysis showed that MMP-7 expression was associated with poor 5-year overall survival (12.8 months vs. 65.3 months, p=0.0405). Multivariate analysis confirmed that MMP-7 was independently associated with an adverse outcome (Relative risk: 1.415, p=0.027). However, MMP-9 expression was not found to be related to clinical outcome. CONCLUSION MMP-7 expression in tumor tissue is associated with lymph node metastasis and a poor 5-year overall survival in rectal cancer patients.

Abstract
We subcloned cell lines from SW620 cells establishing that, despite the dynamic nature of the mitochondrial membrane potential (Deltapsim), there are significant and stable differences in the intrinsic Deltapsim among cells within an in vitro population of human colonic carcinoma cells. Whereas more dramatic differences in Deltapsim would likely perturb essential mitochondrial functions, the differences in Deltapsim of the subclones did not affect steady-state reactive oxygen species levels, electron transport activity, or cellular viability and growth rates. However, the differences in intrinsic Deltapsim had a significant effect on the tumorigenic behavior of the cells. Subcloned cell lines with higher Deltapsim were more likely to exhibit elevated steady-state levels of vascular endothelial growth factor and matrix metalloproteinase 7, and increased invasive behavior (properties associated with tumor progression), than cells with lower intrinsic Deltapsim, whereas cells with lower Deltapsim were more likely to respond to the chemopreventive activities of butyrate, including Deltapsim dissipation, growth arrest, and apoptosis, than cells with higher Deltapsim. Therefore, these data establish that the probability for tumor development and progression is linked to stable differences in the intrinsic Deltapsim of colonic epithelial cells.

Matrix metalloproteinase-7 (MMP-7) (also known as matrilysin-1) is secreted as a proenzyme (proMMP-7) and plays a key role in the degradation of various extracellular matrix (ECM) and non-ECM molecules after activation. To identify the binding proteins related to proMMP-7 activation, a human lung cDNA library was screened by yeast two-hybrid system using proMMP-7 as bait. We identified a candidate molecule CD151, which is a member of the transmembrane 4 superfamily. Complex formation of proMMP-7 with CD151 was demonstrated by immunoprecipitation of the molecules from CaR-1 cells, a human rectal carcinoma cell line, expressing both proMMP-7 and CD151, and CD151 stable transfectants incubated with proMMP-7. Yeast two-hybrid assays using deletion mutants of proMMP-7 and CD151 suggested an interaction between the propeptide of proMMP-7 and the COOH-terminal extracellular loop of CD151. The binding activity of (125)I-labeled proMMP-7 to CD151 on the cell membranes was shown with CD151 stable transfectants. Laser-scanning confocal microscopy demonstrated that proMMP-7 colocalizes with CD151 on the cell membranes of CD151 stable transfectants and CaR-1 cells. In situ zymography using crosslinked carboxymethylated transferrin, a substrate of MMP-7, demonstrated proteinase activity on and around CD151 stable transfectants and CaR-1 cells, while the activity was abolished by their treatment with MMP inhibitors, anti-MMP-7 antibody or anti-CD151 antibody. In human lung adenocarcinoma tissues, colocalization of MMP-7 and CD151 was demonstrated on the carcinoma cells. Metalloproteinase activity was present in these tissues and could be inhibited by antibodies to MMP-7 or CD151. These data demonstrate for the first time that proMMP-7 is captured and activated on the cell membranes through interaction with CD151, and suggest the possibility that similar to the MT1-MMP/MMP-2 system, MMP-7 is involved in the pericellular activation mechanism mediated by CD151, a crucial step in proteolysis on the cell membranes under various pathophysiological conditions including cancer invasion and metastasis.

Abstract
Comparing differential gene expression profiles established by cDNA microarray between normal cells (N), primary carcinoma cells (T), and metastatic carcinoma cells (M) may determine those critical genes directly associated with progression and metastasis of breast cancer. Total RNA was extracted by laser microdissection (LMD) from 20 slices of T, N and M from 6 cases. After amplification by a T7-based system, differentially expressed genes between T, N and M were identified by cDNA microarray. In addition, to clarify the mechanism for altered gene expression, we determined the methylation status by sequencing after bisulfite treatment for intriguing genes. As a result, the expression of motility related protein-1 (MRP-1/CD9), peripheral myelin protein-22 (PMP-22), and caspase 3 (CASP-3) were down-regulated in M compared to T. We focused especially on MRP-1 and found that the expression status of MRP-1 was significantly inversely associated with stage of disease in 56 cases of breast cancer (P<0.05), and the relapse free survival in 5 years was significantly higher in MRP-1 positive cases than those negative cases (P<0.05). Conversely, overexpression, by 11-fold, of signal transduction and translation factors were observed in T compared to N. The cancer specific methylation was observed only in CASP-3 in a case. In conclusion, the establishment of the present assay allows us to detect genes directly associated with each cell population within tumor tissue and gives us clues to identify metastasis-related genes comprehensively in clinical breast cancer cases.

Abstract
PURPOSE Matrix metalloproteinase-7 (MMP-7) plays an important role in carcinoma invasion and metastasis of cancer. Recent studies focus on diverse roles of MMP-7, other than as a protease, during cancer progression. MMP-7 activates the epidermal growth factor (EGF) receptor by releasing an EGF ligand, tumor growth factor (TGF)-alpha. EXPERIMENTAL DESIGN We examined expression of MMP-7 and EGF receptor in an immunohistochemical study of 40 colorectal cancer (CRC) cases. To determine the relationship between the EGF receptor and MMP-7, with a potential curative application, we compared the antitumor activity of the EGF receptor tyrosine kinase inhibitor (gefitinib) between MMP-7 transfectant, KYSE150 and HT29, and control cells. RESULTS We found a statistically significant correlation (P = 0.04) between MMP-7 and activated (phosphorylated) EGF receptor expression, both being positive in six (15%) cases. Gefitinib reduced the cell number ratio more for MMP-7 transfectant than mock cells, and the proportion of apoptotic cells was 1.5 times higher in MMP-7 transfectant than mock cells by annexin/propidium iodide staining. This was mediated by activation of a TGF-beta signal as confirmed by the abundant expression of TGF-beta protein, the cytoplasmic to nuclear translocation of Smad4 protein by the administration of gefitinib, and the quantitative assay of the plasminogen activator inhibitor-1 promoter/luciferase construction. CONCLUSIONS We propose that there are some cancers with up-regulated MMP-7 expression that leads to the activation of apoptotic activity of TGF-beta, which is susceptible to treatment with EGF receptor tyrosine kinase inhibitor.

Abstract
Cell lines pairs were established from a primary squamous carcinoma of tongue and a lymph node metastasis and their biological behavior characterized. HN12 cells, derived from metastatic SCC, formed tumors upon subcutaneous transplantation to athymic mice, whereas HN4, derived from a primary lesion in the same individual, were non-tumorigenic in this assay. EGF stimulated proliferation of HN4 cells; in comparison, not only were metastatic HN12 cells refractory to the stimulatory effects of this growth factor but showed inhibition at higher growth factor concentrations. However, in contrast to the effects on proliferation, EGF (10 ng/ml) readily induced HN12 cells to invade in Boyden chamber assays whereas HN4 were non-invasive under these conditions. The invasive properties of HN12 cells were apparently independent of MMP-2 activity, as levels of active MMP-2 were higher in the non-invasive cells. However, EGF stimulated MMP-9 activity in invasive cells. Additionally, HN12 cells expressed constitutively high levels of active MMP-7 and MMP-3/10. The pharmacological agents LY294002, PD098059, SP600125, or SB202190 inhibited invasion of HN12 cells, suggesting requirement for phosphoinositide 3-OH kinase- and mitogen activated protein kinase-dependent pathways in the process. The data indicate that distinct biochemical differences distinguish metastatic squamous carcinoma cells from those derived from corresponding primary tumors, resulting in their contrasting biological properties.

Abstract
Matrix metalloproteinase-7 (MMP-7) is upregulated during carcinogenesis and its expression correlates with metastasis of human endometrial and gastrointestinal carcinomas. In the present study, we have developed a new method to localize the activity of MMP-7 within tissues. Polyethylene terephthalate films were uniformly coated with crosslinked carboxymethylated transferrin (CCm-Tf) as a substrate and incubated with frozen tissue sections mounted on the films. CCm-Tf on the films was degraded selectively by MMP-7, but showed little or no susceptibility to MMP-1, -2, -3, -9, or -13; MT1-MMP; MT3-MMP; or ADAMTS4. Although some serine proteinases such as elastase also digested CCm-Tf, CCm-Tf films impregnated with serine proteinase inhibitors prevented the digestion. When frozen sections of human endometrial carcinoma and lung carcinoma tissues were incubated on CCm-Tf films or those treated with proteinase inhibitors, the activity was detected in the carcinoma cell nests, where MMP-7 was immunolocalized. The present in situ zymography using CCm-Tf may be a useful method to analyze the functions of MMP-7 in pathophysiological conditions.

Abstract
Cell-matrix and cell-cell adhesive interactions play important roles in the normal organization and stabilization of the cell layer in epithelial tissue. Alterations in the expression and function of these adhesion systems that cause a switch to a migratory phenotype in tumor invasion and metastasis are critical for the malignant conversion of epithelial cells. Thymosin beta-4 (Tbeta-4) is the major actin-sequestering protein that has been shown to be upregulated in a wide variety of human carcinomas and has been implicated to be involved in altering the motility of certain tumors. We have recently demonstrated that the growth rate, colony formation in soft agar, and motility, all good indicators for malignant progression, of SW480 colon carcinoma cells are dramatically increased by enforced Tbeta-4 expression. To test the hypothesis that overexpression of this G-actin sequestering peptide also promotes tumor invasion, we examined not only the invasion capability of Tbeta-4-overexpressing SW480 cells, but also the expression levels of Tbeta-4 as well as several proteins that participate in different stages of tumor progression in matched samples of human primary colorectal adenocarcinoma and liver metastases from several patients. A marked increase on the invasiveness in Tbeta-4-overexpressing SW480 cells with increased levels and activity of matrix metalloproteinase-7 (MMP-7) was observed. Furthermore, the levels of Fas as well as the susceptibility to Fas ligand-mediated apoptosis in Tbeta-4-overexpressing cells were significantly decreased. Interestingly, the levels of Tbeta-4 mRNA, beta-catenin, c-Myc, and MMP-7 in metastatic liver lesions were relatively higher, whereas the levels of E-cadherin and Fas were significantly lower than those in the matched primary colorectal tumors. These results suggest that upregulation of Tbeta-4, by promoting the disruption of cell-cell adhesion and a consequential activation of the beta-catenin signaling, could be a key event in the acquisition of growth advantages as well as invasive phenotypes in human colorectal carcinomas.

Abstract
Matrix metalloproteinase-7 (MMP-7) secreted by cancer cells has been implicated classically in the basement membrane destruction associated with tumor cell invasion and metastasis. Recent epidemiologic studies have established a correlation between high levels of circulating insulin-like growth factor (IGF) and low levels of IGF binding protein 3 (IGFBP-3), and relative risk of developing colon, breast, prostate, and lung cancer, which are known to produce MMP-7. In this study, IGFBP-3 was assessed as a candidate for the physiologic substrate of MMP-7. MMP-7 proteolysis generated four major fragments (26 kDa, 17 kDa, 15.5 kDa, and 15.5 kDa), and two cleavage sites were identified: one at the site of hydrolysis of the K(144)-I(145) peptide bond and one at the R(95)-L(96) peptide bond. The former site is different from the previously reported site of cleavage of IGFBP-3 by other proteases. Addition of IGFBP-3 inhibited IGF-I-mediated IGF type 1 receptor (IGF-IR) phosphorylation and activation of the downstream molecule Akt in BALB/c 3T3 fibroblasts overexpressing human IGF-IR (3T3-IGF-IR) and in two human colon cancer cell lines (COLO201 and HT29). Coincubation of the IGF-I/IGFBP-3 complex with MMP-7 restored IGF-I-mediated IGF-IR phosphorylation and activation of Akt in these cell lines. The IGF-I signal recovered by MMP-7 protected against apoptosis induced by anoikis in 3T3-IGF-IR cells. These results indicate that MMP-7 proteolysis of IGFBP-3 plays a crucial role in regulating IGF-I bioavailability, thereby promoting cell survival. This mechanism may contribute to the tumorigenesis of MMP-7-producing IGF-IR-expressing tumors in the primary site and to organ-specific metastasis in a paracrine manner.

Abstract
BACKGROUND The surface pit pattern of early stage colorectal cancer changes with tumor growth and invasion. It was postulated by us that the expression of matrix metalloproteinase-7 is related to tumor invasiveness and disturbance of the pit pattern. METHODS Sixty-eight colorectal epithelial tumors were examined, and the pit pattern was classified by stereoscopic microscopy. Immunostaining for matrix metalloproteinase-7 and its substrate laminin were performed. RESULTS The rate of matrix metalloproteinase-7 positive staining was significantly higher for mucosal (70.6%) and submucosal cancer (80.0%) than for adenoma (18.6%) (p<0.0083). The rate of matrix metalloproteinase-7 positive specimens was significantly higher for type IV and type V compared with type III pit patterns. Where the tumor surface was positive for matrix metalloproteinase-7, expression of laminin was negative in 40% of specimens with a type IV pit pattern and 100% of those with the type V pit pattern. CONCLUSIONS The results of this study indicate that expression of matrix metalloproteinase-7 is related to both the invasiveness of colorectal epithelial tumors and the disturbance of the pit pattern on the tumor surface.

Abstract
Colorectal cancer (CRC) is a leading cause of morbidity and mortality. Although genetic testing can screen for rare hereditary CRC syndromes, there is no ideal means of screening for sporadic forms of CRC. This review will focus on markers that are currently used in the management of sporadic CRC and their limitations, as well as possible future clinical applications.

Abstract
OBJECTIVES The Ets-1 protooncogene transcription factor is involved in several cellular functions, including the activation of several proteases, and reportedly plays an important role in carcinoma invasion and metastasis. We hypothesize that Ets-1 mRNA expression could be a predictor of thymoma development and invasion. METHODS Subjects were 37 patients with thymoma whose mRNA expression was quantified by real-time reverse-transcription polymerase chain reaction (RT-PCR) using LightCycler, a microvolume multisample fluorimeter. RESULTS No significant difference was found in Ets-1 mRNA expression for gender, age, or pathological subtype. Ets-1 mRNA expression in tumor tissues from stage II-IV thymoma (25.311 +/- 42.336) was more elevated than in that from stage I thymoma (2.097 +/- 4.492) (p = 0.0374). Ets-1 mRNA expression may thus serve as a marker of higher thymoma stages. CONCLUSIONS With use of the Light Cycler RT-PCR assay, Ets-1 expression may play an important role in the extension and progression of thymoma as in other cancers. Further study and longer follow-up are, however, needed to confirm the Ets-1 impact on biological tumor behavior.
