Abstract
BACKGROUND AND AIM The tumor microenvironment plays an essential role in the development and progression of colorectal cancer (CRC). We recently reported that crosstalk between CRC cells and tumor-associated macrophages (TAMs) via serum amyloid A1 (SAA1) promotes invasion by T1 CRCs. In the present study, we aimed to clarify the role of neutrophils in early CRCs. METHODS Immunohistochemical analysis of CD66b, chemokine CXC motif ligand 8 (CXCL8 or interleukin-8, IL-8) and matrix metalloproteinase-9 (MMP-9) was performed using primary T1 CRCs (n = 49). The HL-60 human promyelocytic leukemia cell line and THP-1 human monocytic leukemia cell line were used to obtain neutrophil-like and macrophage-like cells, respectively. Boyden chamber assays were used to analyze cell migration and invasion, and quantitative RT-PCR was used to analyze gene expression. RESULTS Immunohistochemical analysis revealed accumulation of neutrophils at the SAA1-positive invasive front of T1 CRCs. Experiments using HL-60 cells suggested that treatment with SAA1 induced neutrophil migration and expression of CXCL8 and MMP-9 in neutrophils and that neutrophils promote CRC cell migration and invasion. Immunohistochemistry confirmed accumulation of CXCL8- or MMP-9-positive neutrophils at the SAA1-positive invasive front of T1 CRCs. Moreover, co-culture experiments using CRC, THP-1 and HL-60 cells suggested that CRC cells activated by macrophages upregulate CXCL8 and MMP-9 in neutrophils. CONCLUSIONS Our results suggest that interplay between macrophages and CRC cells leads to recruitment of neutrophils to the invasive front of T1 CRCs and that SAA1 secreted by CRC cells activate neutrophils to promote invasion.

High Expression of MMP-9 in Primary Tumors and High Preoperative MPO in Serum Predict Improved Prognosis in Colorectal Cancer with Operable Liver Metastases. Oncology 2020; 99:144-160. [PMID: 33027796 DOI: 10.1159/000510609] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 07/27/2020] [Indexed: 12/24/2022]
Abstract
INTRODUCTION The liver metastases of colorectal cancer (CRC) can be surgically treated in selected cases, with continuously improving results. Matrix metalloproteinases (MMPs) contribute to cancer invasion by degrading the extracellular matrix, and elevated levels of MMP-2, MMP-8, and MMP-9 have been detected in several malignancies. Myeloperoxidase (MPO) is a mediator of tissue damage that can oxidatively activate latent MMPs. We evaluated the prognostic value of MMP-2, MMP-8, and MMP-9 in tissue samples of primary tumors and liver metastases and the pre- and postoperative serum levels of MMP-8, MMP-9, and MPO in CRC patients undergoing liver resection. METHODS Tissue and serum samples were obtained from 111 patients who had primary colorectal tumors and their liver metastases surgically treated at the Helsinki University Hospital between 1988 and 2007. Tissue expression of MMP-2, MMP-8, and MMP-9 in primary tumors and liver metastases was evaluated by immunohistochemistry. Pre- and postoperative serum concentrations of MMP-8, MMP-9, and MPO were determined using a time-resolved immunofluorometric assay or commercially available enzyme-linked immunosorbent assay kits. Clinical data were retrieved from patient records and the Central Statistical Office of Finland. Associations with disease-free survival (DFS) and overall survival (OS) were estimated using Cox regression analysis and the Kaplan-Meier method. RESULTS High expression of MMP-9 in colorectal tumor tissue was associated with better DFS (p = 0.010), and high preoperative MPO in serum with improved DFS and OS (p < 0.001 and p = 0.014, respectively). The prognostic significance varied according to gender, age, and the synchronicity of liver metastases. CONCLUSION Low preoperative MPO in serum might identify patients at high risk of recurrence and death after resection of colorectal liver metastases. Elevated preoperative MPO and high expression of MMP-9 in colorectal tumor tissue indicate an improved prognosis. The use of these biomarkers should be adjusted according to clinical characteristics.

The Role of MMP8 in Cancer: A Systematic Review. Int J Mol Sci 2019; 20:ijms20184506.

Abstract
Matrix metalloproteinases (MMPs) have traditionally been considered as tumor promoting enzymes as they degrade extracellular matrix components, thus increasing the invasion of cancer cells. It has become evident, however, that MMPs can also cleave and alter the function of various non-matrix bioactive molecules, leading to both tumor promoting and suppressive effects. We applied systematic review guidelines to study MMP8 in cancer including the use of MMP8 as a prognostic factor or as a target/anti-target in cancer treatment, and its molecular mechanisms. A total of 171 articles met the inclusion criteria. The collective evidence reveals that in breast, skin and oral tongue cancer, MMP8 inhibits cancer cell invasion and proliferation, and protects patients from metastasis via cleavage of non-structural substrates. Conversely, in liver and gastric cancers, high levels of MMP8 worsen the prognosis. Expression and genetic alterations of MMP8 can be used as a prognostic factor by examination of the tumor and serum/plasma. We conclude, that MMP8 has differing effects on cancers depending on their tissue of origin. The use of MMP8 as a prognostic factor alone, or with other factors, seems to have potential. The molecular mechanisms of MMP8 in cancer further emphasize its role as an important regulator of bioactive molecules.

Abstract
ZKSCAN3, a zinc-finger transcription factor, which has been shown to be upregulated in several human cancer. However, the expression level, function and mechanism of ZKSCAN3 in breast cancer remains unknown. In the current study, immunohistochemistry, western blot and quantitative real time polymerase chain reaction (qRT-PCR) results showed that ZKSCAN3 was overexpressed in breast cancer tissue compared with normal breast tissue. Through analyzing the clinicopathological characteristics, we demonstrated that positive ZKSCAN3 expression predicted poor prognosis of patients with breast cancer. The expression level of ZKSCAN3 protein/mRNA in breast cancer cells (MCF-7 and MDA-MB-231) was higher than its expression in normal breast cells (HBL-100). Knocking down ZKSCAN3 via its short hairpin RNA (shRNA) in MCF-7 and MDA-MB-231 inhibited cell viability, migration and invasion. Western blot analysis showed that ZKSCAN3 silencing lead to significant decreases in the expression of Cyclin D1, B-cell lymphoma-2 (Bcl-2), and matrix metalloproteinase (MMP)-2/MMP-9, as well as increases in the expression of Bcl2 Associated X Protein (Bax) in breast cancer cells. Additionally, ZKSCAN3-shRNA expression markedly suppressed tumor growth in breast cancer xenograft mice. Finally, we demonstrated that silencing of ZKSCAN3 was able to inhibit Akt/mTOR signaling pathway by blocking p-Akt and p-mTOR protein expression in breast cancer cells. These results demonstrate that ZKSCAN3 plays a significant role in the progression of breast cancer. Therefore, ZKSCAN3 is a potential therapeutic target for breast cancer.

Abstract
BACKGROUND Sporadic medullary thyroid cancer (MTC) is a rare neuroendocrine tumor. Currently, although the diagnosis of sporadic MTC is relatively simple, the need to discover novel candidate prognostic biomarkers for sporadic MTC and investigate the underlying mechanism involved in this rare disease is urgent. MATERIALS AND METHODS We employed tandem mass tag-based liquid chromatography-mass spectrometry to identify and analyze differentially expressed proteins (DEPs) in sporadic MTC. Western blotting was used to validate the DEPs. Immunohistochemistry was performed to investigate FN1 and RPS6KA3 in an independent set of sporadic MTC tissues. Immunohistochemical data were analyzed by different statistical methods. RESULTS Three hundred eighty-eight DEPs were identified in mass spectrometry, mainly involved in the extracellular matrix, cytoskeletal remodeling, or oxidoreductase activity. Among them, THBS1, MMP9, FN1, RPS6KA3, SYT1, and carcinoembryonic antigen were successfully validated by Western blot. In addition, FN1 and RPS6KA3, enriched in extracellular matrix (ECM) remodeling and the mitogen-activated protein kinase (MAPK) signaling pathway, respectively, were investigated in an independent set of sporadic MTC tissues. Receiver-operator characteristic curve analysis showed that FN1 and RPS6KA3 can be used for discriminating sporadic MTC tumorous tissues from paired normal thyroid tissues, and the clinical biomarker calcitonin was positively correlated with FN1 and RPS6KA3 in tumorous tissues. Furthermore, the immunohistochemical scores of FN1 in tumorous tissue showed an inverse relationship with tumor classification, lymph node classification, and American Joint Committee on Cancer stage. Through univariate and multivariate analysis for progression-free survival, we also found that low FN1 expression in tumorous tissues was an independent worse prognostic factor for progression-free survival. CONCLUSION We identified that the pathophysiology of sporadic MTC involve numerous pathways, including the synaptic vesicle pathway, the MAPK signaling pathway, and the ECM remodeling pathway. Furthermore, our study also identified FN1 as novel prognostic biomarkers related to the pathophysiologic changes in sporadic MTC. IMPLICATIONS FOR PRACTICE Proteomic dissection and prognostic biomarkers are scarce in sporadic medullary thyroid cancer (MTC). This article reports the use of proteomics technology to comprehensively investigate the molecular mechanisms of sporadic MTC, which resulted in the identification of FN1 as a novel candidate prognostic biomarker.

Abstract
The extracellular matrix (ECM) is one of the most important components within the tumor microenvironment that supports cancer development and metastasis. Under normal physiological conditions, the ECM is a tightly regulated network providing structural and biochemical support. However, the ECM becomes highly disorganized during neoplastic progression and consequently, stimulates cancer cell transformation, growth and spread. Cancer development and progression is also known to greatly benefit from the support of immune myeloid cells, which have multiple pro-tumorigenic functions including promoting tumor growth, migration and invasion, stimulating angiogenesis and suppressing anti-tumor responses. An increasing number of studies have shown that myeloid cells alter the ECM to support metastatic cancer progression and in turn, the ECM can influence the function of infiltrating myeloid cells. However, the exact nature of this relationship, such as the mechanisms employed and their molecular targets remains unclear. This review discusses evidence for the reciprocal dependence of myeloid cells and the tumor ECM for efficient tumor development and explores potential mechanisms involved in these interactions. A better understanding of this relationship has exciting implications for the development of new therapeutic treatments for metastatic cancer.

Abstract
Cholangiocarcinoma (CC) is typically diagnosed at an advanced stage and is refractory to surgical intervention and chemotherapy. Despite a global increase in the incidence of CC, little progress has been made toward the development of treatments for this cancer. Here we utilized human tissue; CC cell xenografts; a p53-deficient transgenic mouse model; and a non-transgenic, chemically induced rat model of CC that accurately reflects both the inflammatory and regenerative background associated with human CC pathology. Using these systems, we determined that the WNT pathway is highly activated in CCs and that inflammatory macrophages are required to establish this WNT-high state in vivo. Moreover, depletion of macrophages or inhibition of WNT signaling with one of two small molecule WNT inhibitors in mouse and rat CC models markedly reduced CC proliferation and increased apoptosis, resulting in tumor regression. Together, these results demonstrate that enhanced WNT signaling is a characteristic of CC and suggest that targeting WNT signaling pathways has potential as a therapeutic strategy for CC.

Abstract
Urokinase plasminogen activator receptor (uPAR) has been proposed as a potential prognostic factor for colorectal cancer (CRC) patient survival. However, CRC uPAR expression remains controversial, especially regarding cell types where uPAR is overexpressed (e.g., epithelium (uPARE) or stroma-associated cells (uPARS)) and associated prognostic relevance. In this study, two epitope-specific anti-uPAR monoclonal antibodies (MAbs) could discriminate expression of uPARE from uPARS and were used to examine this association with survival of stages B and C rectal cancer (RC) patients. Using immunohistochemistry, MAbs #3937 and R4 were used to discriminate uPARE from uPARS respectively in the central and invasive frontal regions of 170 stage B and 179 stage C RC specimens. Kaplan-Meier and Cox regression analyses were used to determine association with survival. uPAR expression occurred in both epithelial and stromal compartments with differential expression observed in many cases, indicating uPARE and uPARS have different cellular roles. In the central and invasive frontal regions, uPARE was adversely associated with overall stage B survival (HR = 1.9; p = 0.014 and HR = 1.5; p = 0.031, respectively) reproducing results from previous studies. uPARS at the invasive front was associated with longer stage C survival (HR = 0.6; p = 0.007), reflecting studies demonstrating that macrophage peritumoural accumulation is associated with longer survival. This study demonstrates that different uPAR epitopes should be considered as being expressed on different cell types during tumour progression and at different stages in RC. Understanding how uPARE and uPARS expression affects survival is anticipated to be a useful clinical prognostic marker of stages B and C RC.

Abstract
Background Non-small cell lung cancer (NSCLC) is one of the leading causes of cancer mortality. MicroRNAs (miRNAs), small noncoding RNAs, regulate the expression of genes that play roles in human cancer via posttranscriptional inhibition. Methods To identify the potential miRNA biomarkers in NSCLC, we downloaded the miRNA expression profile (ID: GSE29248) of NSCLC from the Gene Expression Omnibus (GEO) database and analyzed the differentially expressed miRNAs in NSCLC tissue compared with normal control tissue. Then the targets of these differentially expressed miRNAs were screened and used in network construction and functional enrichment analysis. Results We identified a total of 17 miRNAs that showed a significantly differential expression in NSCLC tissue. We found that miR-34b and miR-520h might play important roles in the regulation of NSCLC, miR-22 might be a novel biomarker as an oncogene, and miR-448 might promote, while miR-654-3p prevents, NSCLC progression. Conclusions Our study may provide the groundwork for further clinical molecular target therapy experiments in NSCLC.

Abstract
The dissemination of cancer cells from the primary tumor to a distant site, known as metastasis, is the main cause of mortality in cancer patients. Metastasis is a very complex cellular process that involves many steps, including the breaching of the basement membrane (BM) to allow the movement of cells through tissues. The BM breach occurs via highly regulated and localized remodeling of the extracellular matrix (ECM), which is mediated by formation of structures, known as invadopodia, and targeted secretion of matrix metalloproteinases (MMPs). Recently, invadopodia have emerged as key cellular structures that regulate the metastasis of many cancers. Furthermore, targeting of various cytoskeletal modulators and MMPs has been shown to play a major role in regulating invadopodia function. Here, we highlight recent findings regarding the regulation of protein targeting during invadopodia formation and function.

Abstract
Despite the new available histologic classification of lung cancers, it remains difficult to assess the real prognostic relevance of the different subtypes of lung adenocarcinomas. Facing the prognostic relevance of microvessel density (MVD) and the expression of metalloproteases and thyroid tyrosine factor 1 (TTF1) in different cancers, we tried to compare these parameters in the different subtypes of lung adenocarcinomas. We conducted a retrospective study of 46 adenocarcinomas surgically resected. An immunohistochemical study using the cluster of differentiation 34 (CD34), TTF1, metalloproteases 2 (MMP2), and metalloproteases 9 (MMP9) antibodies was performed on all samples while MVD was evaluated using CD34 antibody. The analyzed cases included 19 acinar, 7 papillary, 1 lepidic, and 19 solid predominant American Thoracic Classification of lung adenocarcinomas (ASK). The higher MVD levels were observed in papillary and acinar subtypes types and a statically significant difference in the MVD was observed in the different subtypes (p< 0,001). This study didn't show significant statistical results concerning MMP and TTF1 expression but it revealed a tendency to an equal expression of these antibodies in the different subtypes. The difference in the MVD between the different subtypes of adenocarcinoma puts emphasis on their prognostic relevance.

Abstract
Quinazolinone derivatives are known to possess anticancer activities on cell metastasis and cell death in different human cancer cell lines. Here, we studied the anti-metastasis activity and the underlying mechanisms of the novel quinazoline derivative MJ-56 (6-pyrrolidinyl-2-(3-bromostyryl)quinazolin-4-one). MJ-56 inhibited cell migration and invasion of HT29 human colorectal cancer cells by wound-healing and Matrigel-coated transwell assays in a concentration-dependent manner. MJ-56-treated cells resulted in the reduced expression of matrix metalloproteinase (MMP)-2, -7, -9 and -10 and the reduced enzymatic activities of MMP-2 and MMP-9. In contrast, MJ-56-treated cells enhanced the expression of the tissue inhibitors of metalloproteinases (TIMPs) TIMP-1 and TIMP-2. Further analyses showed that MJ-56 attenuated the activities of epidermal growth factor receptor (EGFR), c-Met and the downstream ERK-mediated MAPK and PI3K/AKT/mTOR signaling pathways, which led to decreased protein synthesis by dephosphorylating the translation initiation factors eIF-4B, eIF-4E, eIF-4G and S6 ribosomal protein. In addition, MJ-56 interfered with the NF-κB signaling via impairing PI3K/AKT activation and subsequently reduced the NF-κB-mediated transcription of MMPs. Taken together, the reduced expression of phosphor-EGFR and c-MET is chiefly responsible for all events of blocking metastasis. Our results suggest a potential role of MJ-56 on therapy of colorectal cancer metastasis.

Abstract
Background Matrix metalloproteinases (MMPs) play a role in cancer progression by degrading extracellular matrix and basement membranes, assisting in tumour neovascularization and in supporting immune response in cancer. Methods We studied the prognostic value of immunohistochemical expression of MMP-2, MMP-8, and MMP-9 in a series of 619 colorectal cancer patients using tissue microarray specimens. Results Of the samples, 56% were positive for MMP-2, 78% for MMP-8, and 60% for MMP-9. MMP-9 associated with low WHO grade (p < 0.001). In univariate analysis of Dukes’ B tumours, MMP-9 negativity associated with poor survival (p = 0.018), and MMP-9 positivity was an independent prognostic marker in multivariate analysis of these tumours (p = 0.034). Conclusion Negative MMP-9 expression can predict poor prognosis in Dukes’ B colorectal tumours and may prove useful for identifying patients, who should be offered adjuvant treatment.

Abstract
The oncoprotein stathmin 1 (STMN1) is upregulated in most, if not all, cancers of epithelial cell origin; therefore STMN1 is considered a target for cancer therapy. However, its role during metastasis has not been investigated. Here, we report for the first time that STMN1 strongly inhibits metastatic behavior in both normal epithelial and cancerous epithelial cells. Initially, loss-of-STMN1 compromises cell-cell adhesion. This is followed by epithelial-to-mesenchymal transition (EMT), increased cell migration, and metastasis via cooperative activation of p38 and through TGF-β-independent and -dependent mechanisms. In contrast, expressing STMN1 restores cell-cell adhesion and reverses the metastatic cascade. Primary prostate epithelial cell cultures from benign to undifferentiated adenocarcinoma (UA) clinical biopsies show that EMT-like cells arise while the cancer is still organ-confined and that their emergence is tumor-stage specific. Furthermore, primary EMT-like cells exhibit metastatic behavior both in vitro and in vivo as compared with their non-EMT counterpart. These observations predict that using STMN1 as a generic therapeutic target might accelerate metastasis. Instead, there may be a tumor stage-specific window-of-opportunity in which conserving STMN1 expression is required to inhibit emergence of metastatic disease.

Abstract
Background Matrix metalloproteases (MMPs) are proteolytic enzymes that contribute to all stages of tumour progression, including the later stages of invasion and metastasis. Genetic variants in the MMP genes may influence the biological function of these enzymes and change their role in carcinogenesis and progression. We have investigated the association between the -735 C/T, the -1171 5A/6A, and the -1562 C/T polymorphisms in the MMP2, MMP3 and MMP9 genes, respectively, and the risk and survival of lung cancer. Methods The case-control study includes 879 lung cancer patients and 803 controls from a Caucasian population in Spain (CAPUA study). Genotypes were determined by PCR-RFLP. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using unconditional logistic regression. The Kaplan-Meier method, long-rank test and Cox's were used for the survival analysis. Results The MMP9 -1562 T/T genotype was associated with a statistically significant decreased risk of developing lung cancer (OR = 0.23; 95% CI: 0.06-0.85), whereas no association was found for the MMP2 -735 C/T and MMP3 -1171 5A/6A polymorphisms. The MMP2 -735 T/T genotype was statistically significantly associated with a decreased survival in non-small cell lung cancer (NSCLC) patients, identified as an independent prognosis factor of survival (hazard ratio (HR) = 1.79; 95% CI: 1.00-3.20). In contrast, no association was found between the MMP3 -1171 5A/6A and the MMP9 -1562 C/T polymorphisms and survival. Conclusions These findings support the hypothesis that the MMP9 -1562 C/T polymorphism is associated with a protective effect against the development of lung cancer and suggest that the MMP2 -735 C/T polymorphism modify the length of survival in NSCLC patients.

Abstract
BACKGROUND Most pancreatic ductal adenocarcinomas (PDACs) metastasize even after curative resection. Our goal was to investigate the important factors affecting metastasis and overall survival (OS). METHODS We studied 88 PDACs with R0 resection and evaluated immunohistochemical markers on tissue microarrays to assess the expression levels of the following: EGFR, amphiregulin, VEGF, p-c-met, MMP2, MMP7, MMP9, CXCR3, and CXCR4. RESULTS The median OS in patients who had positive versus negative expression of AREG and MMP9 were 25 versus 16 months and 24 versus 13 months, respectively (P = 0.03, P = 0.006). However, the median OS in patients with positive versus negative expression of MMP2 was 22 versus 37 months (P = 0.04). Immunoprofiles also revealed that patients with positive expression of p-c-met or VEGF had significantly shorter distant metastasis-free survival. Adjuvant treatment, postoperative decrease of CA 19-9, angiolymphatic invasion, AREG, and MMP2 were independent prognostic factors affecting OS in multivariate analysis. CONCLUSIONS Immunoprofiles revealed the groups with unfavorable tumor biology: negative expression of AREG and positive expression of MMP2. Also, high immunoreactivity of p-c-met or VEGF seemed to be associated with early distant organ metastasis in R0 resected PDACs; however, they still need to be further investigated. These results may give us useful insights in understanding the tumor biology and the patterns of PDAC dissemination.

Abstract
A previous study indicated that lycopene could significantly inhibit the proliferation of human colon cancer cells in vitro. However, the in vivo anticancer effects of lycopene against colon cancer have not been demonstrated yet. Therefore, this study investigated whether consumption of lycopene could prevent the growth and progression of colorectal tumor in a mouse xenograft model. Bioluminescence imaging, histopathological, immunofluorescence (IFC), and immunohistochemical (IHC) staining results indicated that lycopene could effectively suppress the growth and progression of colon cancer in tumor-bearing mice. The results demonstrated that lycopene significantly suppressed the nuclear expression of PCNA and β-catenin proteins in tumor tissues. Consumption of lycopene could also augment the E-cadherin adherent molecule and nuclear levels of cell cycle inhibitor p21(CIP1/WAF1) protein. The chemopreventive effects of lycopene were associated with suppression of COX-2, PGE(2), and phosphorylated ERK1/2 proteins. Furthermore, the inhibitory effects of lycopene were inversely correlated with the plasma levels of matrix metalloproteinase 9 (MMP-9) in tumor-bearing mice. These results suggested that lycopene could act as a chemopreventive agent against the growth and progression of colorectal cancer in a mouse xenograft model.

Abstract
We and others previously showed that protein kinase D1 (PKD1) is downregulated in several cancers including prostate; interacts with E-cadherin, a major cell adhesion epithelial protein; and causes increased cell aggregation and decreased motility of prostate cancer cells. In this study, we show that PKD1 complexes with beta3-integrin, resulting in activation of mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) kinase-ERK pathway, which causes increased production of matrix metalloproteinase (MMP)-2 and MMP-9, that is associated with shedding of soluble 80 kDa E-cadherin extracellular domain. Interestingly, decreased cell proliferation following PKD1 transfection was rescued by MMP-2 and MMP-9 inhibitors and augmented by recombinant MMP-2 (rMMP-2) and rMMP-9 proteins, suggesting an antiproliferative role for MMPs in prostate cancer. Translational studies by in silico analysis of publicly available DNA microarray data sets show a significant direct correlation between PKD1 and MMP-2 expression in human prostate tissues. The study shows a novel mechanism for antiproliferative effects of PKD1, a protein of emerging translational interest in several human cancers, through increased production of MMP-2 and MMP-9 in cancer cells.

Abstract
BACKGROUND Extracellular matrix metalloprotease inducer (EMMPRIN) induces matrix metalloproteinase (MMP) expression, tumor-stroma cell interaction, and invasion/angiogenesis. The objectives of the current study were to find the first evidence of a prognostic impact of total and relative EMMPRIN expression in colorectal cancer cells and to analyze EMMPRIN in bone marrow-disseminated tumor cells and normal cells from 2 different gastrointestinal cancer entities. METHODS Tumors and normal tissues from 40 patients with colorectal cancer who were followed prospectively (median follow-up, 31 months) were analyzed for EMMPRIN by immunohistochemistry. Bone marrow from 51 patients (13 patients with gastric cancer and 38 patients with colorectal cancer) with evidence of disseminated tumor cells was screened for EMMPRIN in tumor cells and normal cells (cytokeratin 18/EMMPRIN double immunocytochemistry). RESULTS A significant correlation between poor disease-specific survival (P=.037; Kaplan-Meier method; Mantel-Cox log-rank tests) and an increased ratio of EMMPRIN in tumor cells versus corresponding normal epithelial cells were observed. Furthermore, the relative increase of EMMPRIN was associated with a trend toward poor overall and recurrence-free survival. High relative EMMPRIN expression was associated significantly with positive metastasis status (M1) (P=.001) and with a trend towards advanced pathologic tumor classification. Sixteen percent of disseminated tumor cells in bone marrow samples from patients with colorectal cancer and 48.5% of disseminated tumor cells in bone marrow samples from patients with gastric cancer stained positive for EMMPRIN, and EMMPRIN on micrometastatic cells was associated significantly with parameters of tumor progression (M status, noncurative resectability). A minority of normal bone marrow cells were stained for EMMPRIN, suggesting their suitability for molecular targeting. CONCLUSIONS To the authors' knowledge, this study was the first to indicate that increased relative EMMPRIN protein in tumor-specific cells compared with normal cells predicts poor disease-specific survival in patients with colorectal cancer and that EMMPRIN in primary and bone marrow-disseminated tumor cells is associated with clinical markers of tumor progression in patients with colorectal/gastric cancer.

Abstract
The tumor microenvironment plays an important role equal to the tumor cell population in the progression of cancer. Consisting of stromal fibroblasts, inflammatory cells, components of the vasculature, normal epithelia, and extracellular matrix, the surrounding environment interacts or "cross-talks" with tumor cells through the release of growth factors, cytokines, proteases, and other bioactive molecules. Tumor growth, formation of new vascular networks, evasion of the host immune system, and invasion and metastasis are processes that co-evolve and become finely optimized and regulated within the tumor microenvironment. However, relatively recent reports on three areas of study have come together to add new levels of complexity to the tumor microenvironment. These include ectodomain shedding of proteins, shedding of membrane-derived vesicles, and novel roles for phospholipids. These dynamic changes that take place in the tumor microenvironment provide new avenues for study and for the early detection of cancer, whereas proteomic technologies provide the means to detect these unique proteins and lipids. Here we review the evolving concepts of the tumor microenvironment that, together with advances in proteomic technologies, hold the promise to facilitate the detection of early-stage cancer.

Abstract
Integrin alpha v beta 6 (alpha v beta 6) is correlated with colon cancer progression. To detect the effects of alpha v beta 6 on liver metastasis, the specificity of alpha v beta 6 against the monoclonal antibody (mAb) 2G2 was examined by immunoprecipitation. Integrin alpha v beta 6-immunoreactivity (IR) in liver metastasis tissues (63 cases) and colon carcinoma (358 cases) were examined. These results showed that alpha v beta 6 was specifically recognized by the mAb 2G2, and that rates of alpha v beta 6 positivity in liver metastatic tissues (71.4%, 45/63) were higher than that for primary colon cancer (34.0%, 122/358) (P < 0.01). Patients who were alpha v beta 6-positive had higher liver metastasis rates (17%, 21/122) than those who were alpha v beta 6-negative (only 3%, 7/236) (P < 0.01). To examine the underlying mechanisms associated with alpha v beta 6 regulating colonic metastasis in the liver, experimental liver metastasis (intrasplenic injection of HT29 transfectants) and liver colonization assays (direct injection of WiDr transfectants into the liver) in nude mice were performed; these demonstrated that alpha v beta 6 contributed to the promotion of the metastatic potential and the survival of cancer cells in the liver. Matrix metalloproteinase-9 (MMP-9) levels in the cultures of both HT29 and WiDr cells were detected by the Biotrak MMP-9 activity assay system and gelatin zymography assay, and showed that suppression of alpha v beta 6-IR inhibited MMP-9 activity and secretion. Transwell migration assay in vitro also showed that alpha v beta 6 promoted migration on fibronectin for HT29/WiDr mock compared with HT29/WiDr antisense beta 6 transfects (P < 0.01). We concluded that alpha v beta 6 may mediate the potential for colon cancer cells to colonize in and metastasize to the liver. The mechanisms that alpha v beta 6 may be involved in include the promotion of MMP-9 secretion, the enhancement of migration on fibronectin, and the survival of cancer cells in the liver.

Abstract
Proteases have long been associated with cancer progression because of their ability to degrade extracellular matrices, which facilitates invasion and metastasis. However, recent studies have shown that these enzymes target a diversity of substrates and favour all steps of tumour evolution. Unexpectedly, the post-trial studies have also revealed proteases with tumour-suppressive effects. These effects are associated with more than 30 different enzymes that belong to three distinct protease classes. What are the clinical implications of these findings?

Abstract
OBJECTIVE We investigated the expression of matrix metalloproteinase-9 (MMP-9) and its relation to clinicopathologic factors and survival and also to previously analyzed expressions of CD44 and hyaluronan in epithelial ovarian cancer. METHODS The expression of MMP-9 was analyzed immunohistochemically in 292 primary tumors and their 31 metastases. RESULTS A low proportion of strong MMP-9 expression in cancer cells and high stromal MMP-9 expression correlated with advanced stage of the tumor (p=0.003, p=0.02, respectively). Stromal MMP-9 expression significantly correlated with hyaluronan positivity (p<0.0005), whereas MMP-9 did not correlate with CD44. In univariate analysis, a longer 10-year disease-related survival (DRS) was found in patients with a high proportion of MMP-9 or strong MMP-9 expression in cancer cells (p=0.02, p=0.05, respectively). However, high stromal expression of MMP-9 indicated short DRS (p=0.01). In multivariate analysis of all patients, MMP-9 expressing cancer or stromal cells were not independent prognostic factors, while in FIGO stage I patients a high percentage of MMP-9 positive cancer cells was associated with long DRS (p=0.008). CONCLUSION These data suggest that MMP-9 has a dual role in tumor progression, acting against tumor advancement when in tumor epithelium and promoting tumor progression while in the stroma.

Abstract
Cancer research has mainly focused on alterations of genes and proteins in cancer cells themselves that result in either gain-of-function in oncogenes or loss-of-function in tumour-suppressor genes. However, stromal variables within or around tumours, including blood and lymph vessels, stromal cells and various proteins, have also important impacts on tumour development and progression. It has been shown that disruption of stromal-epithelial interactions influences cellular proliferation, differentiation, death, motility, genomic integrity, angiogenesis, and other phenotypes in various tissues. Moreover, stromal variables are also critical to therapy in cancer patients. In this review, we mainly focus on the clinicopathological significance of stromal variables including angiogenesis, lymphangiogenesis, inflammatory infiltration, matrix metalloproteinase (MMP), and the particularly interesting new cysteine-histidine rich protein (PINCH) in colorectal cancer (CRC).

Abstract
Matrix metalloproteinase-9 (MMP-9) is up-regulated in macrophages in various human cancer types. In human colon cancer, MMP-9 is expressed in a macrophage subpopulation located at the tumor edge, indicating a specific induction of MMP-9 in macrophages in direct association with cancer invasion. To test whether MMP-9 is also induced in tumor edge macrophages in metastases from colorectal adenocarcinomas, we have compared the expression pattern of MMP-9 in primary colorectal adenocarcinomas (n = 15) with that in liver metastases (n = 15) and local lymph node metastases (n = 7) from the same patients by in situ hybridization and immunohistochemistry. In all the colorectal adenocarcinomas, the expression of MMP-9 mRNA and immunoreactivity in macrophages was located at the invasive front. In contrast, only 3 of the 15 liver metastases had MMP-9 mRNA and immunoreactivity at the periphery, and this expression was confined to small foci of macrophages located either among lymphocytes or in a dense desmoplastic stroma. Expression of MMP-9 mRNA and immunoreactivity was in all liver metastases seen in macrophages located in the lumen of malignant glandular structures and in central necrotic tissue. In all the 7 lymph node metastases, MMP-9 mRNA and immunoreactivity was seen in macrophages located in the stromal tissue surrounding the metastases. We conclude that MMP-9 is not up-regulated in tumor edge macrophages in liver metastases like in their primary tumor and local lymph node metastases, suggesting that disseminating colorectal cancer cells can adopt alternative proteolytic mechanisms for invasion depending on the local microenvironment.

Abstract
Molecular markers can provide additional information to traditional histomorphological evaluation for the assessment of tumor progression and predicting the likelihood of invasion and metastasis in various types of malignancies. We studied the association of E-cadherin, matrix metalloproteinases (MMPs), and tissue inhibitors of metalloproteinase with the progression and metastasis of hepatocellular carcinoma. Tissue microarray including six normal livers, 14 cirrhotic livers, 39 macroregenerative nodules, 16 dysplastic nodules, 22 grade I hepatocellular carcinomas, 43 grade II hepatocellular carcinomas, seven grade III hepatocellular carcinomas, and 10 metastatic hepatocellular carcinomas were stained immunohistochemically with antibodies against MMPs -1, -2, -3, -7, -9, tissue inhibitors of metalloproteinase-1, -2, -3, and E-cadherin. The intensities of staining were scored manually by two pathologists and verified by the Chromavision Automated Cellular Imaging System. Compared with normal liver, cirrhotic liver had significantly lower E-cadherin and tissue inhibitors of metalloproteinase-1 but higher MMP-1 and -7, which suggest a more favorable environment for tumor invasion and metastasis. Grade I and grade II hepatocellular carcinomas demonstrated high E-cadherin and decreased MMP-3 and -9, which may explain the rarity of extrahepatic metastasis in low-grade hepatocellular carcinomas despite the high circulatory volume of the liver. The histological progression from dysplastic nodule to well-differentiated hepatocellular carcinoma and to less differentiated tumors was associated with a gradual decrease in tissue expression of E-cadherin, tissue inhibitors of metalloproteinase-2 and -3. Metastatic hepatocellular carcinomas showed significantly lower level of tissue inhibitors of metalloproteinase-1, -2, -3 but higher level of MMP-7. These data suggest that tissue expression of E-cadherin, certain MMPs, and tissue inhibitors of metalloproteinases could be useful markers to predict the progression and metastasis of hepatocellular carcinoma.

Abstract
PURPOSE Members of the small integrin binding ligand N-linked glycoprotein (SIBLING) gene family have the capacity to bind and modulate the activity of matrix metalloproteinases (MMPs). The expression levels of five SIBLING gene family members [bone sialoprotein (BSP), osteopontin (OPN), dentin matrix protein 1 (DMP1), matrix extracellular phosphoglycoprotein (MEPE), and dentin sialophosphoprotein (DSPP)] and certain MMPs were determined using a commercial cancer array. EXPERIMENTAL DESIGN Cancer profiling arrays containing normalized cDNA from both tumor and corresponding normal tissues from 241 individual patients were used to screen for SIBLING and MMP expression in nine distinct cancer types. RESULTS Significantly elevated expression levels were observed for BSP in cancer of the breast, colon, stomach, rectum, thyroid, and kidney; OPN in cancer of the breast, uterus, colon, ovary, lung, rectum, and thyroid; DMP1 in cancer of the breast, uterus, colon, and lung; and dentin sialophosphoprotein in breast and lung cancer. The degree of correlation between a SIBLING and its partner MMP was found to be significant within a given cancer type (e.g., BSP and MMP-2 in colon cancer, OPN and MMP-3 in ovarian cancer; DMP1 and MMP-9 in lung cancer). The expression levels of SIBLINGs were distinct within subtypes of cancer (e.g., breast ductal tumors compared with lobular tumors). In general, SIBLING expression increased with cancer stage for breast, colon, lung, and rectal cancer. CONCLUSIONS These results suggest SIBLINGs as potential markers of early disease progression in a number of different cancer types, some of which currently lack vigorous clinical markers.

Abstract
The matrix metalloproteinases(MMP)-2 and -9, also known as the gelatinases have been long recognized as major contributors to the proteolytic degradation of extracellular matrix during tumor invasion. In the recent years, a plethora of non-matrix proteins have also been identified as gelatinase substrates thus significantly broadening our understanding of these enzymes as proteolytic executors and regulators in various physiological and pathological states including embryonic growth and development, angiogenesis and tumor progression, inflammation, infective diseases, degenerative diseases of the brain and vascular diseases. Although the effect of broad-spectrum inhibitors of MMPs in the treatment of cancer has been disappointing in clinical trials, novel mechanisms of gelatinase inhibition have been now identified. Inhibition of the association of the gelatinases with cell-surface integrins appears to offer highly specific means to target these enzymes without inhibiting their catalytic activity in multiple cell types including endothelial cells, tumor cells and leukocytes. Here, we review the multiple functions of the gelatinases in cancer, and especially their role in the tumor cell migration and invasion.

Abstract
PURPOSE The purpose is to assess clinical significance of matrix metalloproteinase (MMP)-2 and MMP-9 status, especially MMP-2 status, in stromal cells in non-small-cell lung cancer (NSCLC) because experimental studies have revealed that stromal MMP-2 plays important roles in progression of malignant tumors, but most clinical studies focused on tumoral MMP-2 expression, not stromal MMP-2 expression. EXPERIMENTAL DESIGN We conducted a retrospective study on MMP-2 and MMP-9 expression as evaluated immunohistochemically in a total of 218 consecutive patients with completely resected pathological stage I-IIIA, NSCLC. RESULTS Strong MMP-2 expression in tumor cells and stromal fibroblasts were documented in 54 (24.8%) and 132 (60.6%) patients, respectively. Strong MMP-2 expression in stromal fibroblasts was more frequently seen in squamous cell carcinoma (72.7%) than in adenocarcinoma (54.9%; P = 0.016). Tumors showing strong MMP-2 expression in stromal fibroblasts showed a significantly higher intratumoral microvessel density (IMVD) than weak stromal MMP-2 tumors (mean intratumoral microvessel density, 50.9 versus 32.4, P = 0.003). In addition, postoperative prognosis of strong stromal MMP-2 patients was significantly poorer than that of weak stromal MMP-2 patients (5-year survival rate, 77.5 versus 60.2%, P = 0.032), and the prognostic significance was enhanced in squamous cell carcinoma patients but disappeared in adenocarcinoma patients. Multivariate analyses confirmed that strong stromal MMP-2 expression was a significant factor to predict a poor prognosis in squamous cell carcinoma patients, not in adenocarcinoma patients. In contrast, MMP-2 or MMP-9 status in tumor cells was not a significant prognostic factor. CONCLUSIONS MMP-2 status in stromal fibroblasts, not in tumor cells, was a significant prognostic factor associated with angiogenesis in NSCLC.

Abstract
AIMS Platelet-derived endothelial cell growth factor (PD-ECGF) is an angiogenic factor that undergoes increased expression in colorectal carcinomas, but its prognostic value is a topic of debate. The aim of this study is to clarify the prognostic value of PD-ECGF expression in colorectal carcinomas. METHODS PD-ECGF expression was measured by enzyme-linked immunosorbent assay in frozen materials from 134 colorectal cancer patients who had received curative resections. Patients were divided into high expression and low expression groups based upon selected cut-off value. Correlations among PD-ECGF expression, clinicopathologic features, and disease-free interval were studied by univariate and multivariate analysis. To evaluate the origin of PD-ECGF, serial sections of the 134 tumours were stained for PD-ECGF and CD68. RESULTS PD-ECGF expression in the normal mucosa was 34.4+/-15.5 (Units/mg protein) and the cut-off value was 65.4 (mean+2SD). There were no significant correlations between clinicopathological features and PD-ECGF expression. The disease-free interval for the high PD-ECGF expression group was significantly longer than that of the low expression group (P=0.05). A multivariate Cox's regression analysis revealed that high PD-ECGF expression is an independent factor for better outcome. In immunohistochemical study, almost all tumour cells were negative for PD-ECGF, but stromal macrophages were predominantly positive for PD-ECGF. CONCLUSIONS The PD-ECGF expression originated from stromal macrophages was a predictor for favorable outcome after curative resections for colorectal cancer.

Abstract
Matrix metalloproteinases (MMPs) are a growing family of metalloendopeptidases that cleave the protein components of the extracellular matrix and thereby play a central role in tissue remodelling. For many years following their discovery, MMPs were believed to function primarily as regulators of ECM composition and to facilitate cell migration simply by removing barriers such as collagen. It is becoming increasingly clear, however, that MMPs are implicated in the functional regulation of a host of non-ECM molecules that include growth factors and their receptors, cytokines and chemokines, adhesion receptors and cell surface proteoglycans, and a variety of enzymes. MMPs therefore play an important role in the control of cellular interactions with and response to their environment in conditions that promote tissue turnover, be they physiological, such as normal development, or pathological, such as inflammation and cancer. This review summarizes some of the recent discoveries that have shed new light on the role of MMPs in physiology and disease.

Abstract
BACKGROUND Matrix metalloproteinase 9 (MMP-9) plays a key role in tumor cell invasion. It was recently reported that plasma levels of MMP-9 in patients with gastric cancer correlate with the tumors' metastatic potential. We previously demonstrated that thrombospondin 1 (TSP-1) up-regulates MMP-9 expression by endothelial cells and promotes tumor cell invasion. We hypothesized that TSP-1 plays a role in the up-regulation of MMP-9 in gastric cancer. METHODS MMP-9, TSP-1, and CSVTCG-specific TSP-1 receptor expression were measured by immunohistochemical staining in 31 consecutive gastric adenocarcinomas from patients who did not undergo neoadjuvant chemotherapy or radiation therapy. Additionally, we measured TSP-1, CSVTCG-specific TSP-1 receptor, and MMP-9 expression by Western blotting, zymography, and immunohistochemical staining in AGS gastric adenocarcinoma cells. We also investigated the effect of TSP-1 on MMP-9 expression by AGS cells. RESULTS TSP-1 localized to the tumor-associated extracellular matrix. CSVTCG-specific TSP-1 receptor and MMP-9 colocalized to tumor cells, fibroblasts, and tumor-associated microvessels. Intense staining for TSP-1, CSVTCG-specific TSP-1 receptor, and MMP-9 correlated with markers of aggressive tumor behavior. AGS gastric adenocarcinoma cells expressed high levels of CSVTCG-specific TSP-1 receptor but not TSP-1. TSP-1 up-regulated MMP-9 expression by AGS cells. CONCLUSIONS We conclude that TSP-1 plays a role in the up-regulation of MMP-9 expression in gastric cancer. Our data also suggest a correlation between expression of TSP-1, CSVTCG-specific TSP-1 receptor, and MMP-9 and the acquisition of an aggressive tumor phenotype.

Abstract
The bioactivity of matrix metalloproteinases was studied in tissues from colorectal cancer patients by means of both quantitative gelatin zymography and a fluorometric activity assay. Next to paired samples of tumour tissue and distant normal mucosa (n=73), transitional tissue was analysed from a limited (n=33) number of patients. Broad-spectrum matrix metalloproteinase activity and both the active and latent forms of the gelatinases matrix metalloproteinase-2 and -9 were higher in tumour than in normal mucosa. The ratio's between active and latent forms of matrix metalloproteinase-2 and -9 were highest in tumour tissue and normal mucosa, respectively. Matrix metalloproteinase-2 levels, both active and latent forms, correlated inversely with stage of disease, the tumours without synchronous distant metastases containing significantly (P=0.005) more active matrix metalloproteinase-2 than the others. At much lower levels of activity, the same trend was observed in distant normal mucosa. The level of latent form of matrix metalloproteinase-9 in tumour depended on tumour location. Neither the active form of matrix metalloproteinase-9 nor broad-spectrum matrix metalloproteinase activity in tumour tissue did correlate with any of the clinicopathological parameters investigated. The results demonstrate explicit differences between the activity of matrix metalloproteinase-2 and -9, indicating different roles for both gelatinases in tumour progression. Such data are necessary in order to develop rational anti-cancer therapies based on inhibition of specific matrix metalloproteinases.

Abstract
BACKGROUND AND OBJECTIVES Matrix metalloproteinases (MMPs) are known to play an important role in carcinoma cell invasion and hematogenous metastasis by mediating the degradation of the extracellular matrix. METHODS We investigated the relationship between MMP-2 and -9 enzymatic activities and liver metastases in human pancreatic and colon carcinomas, using xenograft tumors in nude mice. RESULTS We found that type IV collagenase activity in pancreatic and colon carcinomas with liver metastases was significantly higher than in pancreatic and colon carcinomas without liver metastases. Gelatin zymography showed the presence of gelatinolytic activity bands at M(r) 92,000 and 72,000, indicating MMP-9 and MMP-2, respectively. MMP-2 and -9 expression levels in pancreatic and colon carcinomas with liver metastases were higher than in pancreatic and colon carcinomas without liver metastases. TIMP-2 levels in pancreatic and colon carcinomas with liver metastases were also higher than in those without liver metastases. CONCLUSIONS MMP-2 and MMP-9 expression in primary tumors is associated with liver metastases in pancreatic and colon carcinomas. In addition, the balance of activity between MMP-2, MMP-9, and TIMP-2 may be relevant to carcinoma invasion and metastasis, including liver metastases in pancreatic and colon carcinoma.

Abstract
Matrix metalloproteinases (MMPs) have long been associated with cancer-cell invasion and metastasis. This provided the rationale for clinical trials of MMP inhibitors, unfortunately with disappointing results. We now know, however, that the MMPs have functions other than promotion of invasion, have substrates other than components of the extracellular matrix, and that they function before invasion in the development of cancer. With this knowledge in hand, can we rethink the use of MMP inhibitors in the clinic?

Abstract
Matrix metalloprotease-9 (MMP-9; 92 kDa type IV collaganase, gelatinase B) is regarded as, important for degradation of the basement membrane and extracellular matrix during cancer invasion and other tissue-remodelling events. In this study we evaluate the prognostic value of MMP-9, by immunoperoxidase staining in a series of 210 breast cancer tissues. The results were quantitated using the HSCORE system, which consider both staining intensity and the percentage of cells stained at given intensities. MMP-9 status was compared with the concentration of cytosolic Cathepsin-D and with other established prognostic factors, in terms of disease free survival and overall survival. The median follow-up period was 62 months. MMP-9 staining was observed primarily in cancer cells, and to a lesser degree in surrounding stromal cells. MMP-9 expression was not detected in normal breast tissue. Levels of MMP-9 expression below the cut-off point were more frequently observed in larger (P = 0.014), invasive ductal histologic (P = 0.037), progesterone receptor (PR)-negative and PR-strong positive tumours (P< 0.001), as well as samples belonging to patients with stage III-IV disease (P = 0.009) and age 45-55 years (P = 0.011). In univariate analysis, node-negative breast cancer patients with tumors positive for MMP-9 had a considerable reduction in risk for relapse (RR = 0.45;P = 0.039) or death (RR = 0.32;P = 0.009). Multivariate analysis indicated that MMP-9 status was an independent favourable predictor of OS (RR = 0.47;P = 0.034) in node-negative but not in node-positive patients. Our results suggest that MMP-9 may be an independent favourable prognostic factor in node-negative breast cancer patients. The overexpression of MMP-9 in breast cancer may be also used as a marker to subdivide node negative breast cancer patients in order to determine the optimal treatment modality.

Abstract
Matrix metalloproteinase-1 (MMP-1) is involved in the degradation of interstitial collagen and thus thought to play a role in invasion of carcinoma. We investigated 51 oesophageal carcinoma patients to clarify the significance of MMP-1. MMP-1 mRNA was demonstrated to be expressed exclusively in almost all carcinoma tissue specimens (T) (94.1%) by reverse transcription-polymerase chain reaction, but not found in normal mucosal tissue specimens (N). The mean T/N ratio of MMP-1 was 42.5 and cases with T/N > or = 10 had a higher incidence of cases involving muscularis propria than those with T/N < 10 which included all the cases involving the submucosa (P< 0.05). MMP-1 mRNA was significantly associated with both 40 kD (putative active MMP-1) and 50 kD (putative latent MMP-1) gelatinolytic bands (n = 17). These findings indicated that MMP-1 mRNA reflected the net function of MMP-1 and suggested MMP-1 to be involved in carcinoma invasive process. On the other hand, MMP-1 mRNA was inversely correlated with the patient prognosis (P< 0.01). These results indicated that MMP-1 might therefore play a crucial role in local invasion, but not in systemic dissemination. As a result, MMP-1 might be a novel prognostic factor independent from those previously reported in oesophageal carcinoma.

Abstract
Our previous clinicopathologic study revealed an inverse association of liver metastasis of colorectal cancer and stromal expression of matrix metalloproteinase-9 (MMP-9) or urokinase receptor (uPAR). This suggests that host cells, particularly macrophages, expressing matrix-degrading enzymes/factors could be protective for the host against hematogenous metastasis. However, our previous study was unable to differentiate whether our results were causes or effects of widely spread cancer. To solve this point, we designed the present study on colorectal cancers that developed hematogenous metastasis after operation, ie., metachronous hematogenous metastasis. These cancers, being solely micrometastasized at the time of operation, allowed us to eliminate possible systemic effects by widely spread cancer. Sixty-two primary tumors with metachronous metastasis showed a decreased number of MMP-9+ stromal cells and CD68+ macrophages along the invasive margin with unchanged uPAR+ stromal area as compared with those in 72 control cases, which were free from tumor metastasis or recurrence for more than 5 years. Therefore, we judged the decrease of MMP-9+ host cells or macrophages in the primary site is irrelevant of effects of widely spread metastasis but probably related to causes of metastasis. Our data also characterized the metachronous metastasis group by uPAR expression in fibroblasts. The number of uPAR+ cancer cells, although small in number, were also larger in the metachronous metastasis group. Our data revealed that macrophages, a major source of uPAR and one of the sources of MMP-9, could be inhibitory to hematogenous metastasis, while uPAR+ fibroblasts and cancer cells, in turn, facilitate hematogenous metastasis. This suggests the functional multiplicity of matrix degradation processes in cancer tissue.

Abstract
Tumor progression is a complex, multistage process by which a normal cell undergoes genetic changes that result in phenotypic alterations and the acquisition of the ability to spread and colonize distant sites in the body. Although many factors regulate malignant tumor growth and spread, interactions between a tumor and its surrounding microenvironment result in the production of important protein products that are crucial to each step of tumor progression. The matrix metalloproteinases (MMPs) are a family of degradative enzymes with clear links to malignancy. These enzymes are associated with tumor cell invasion of the basement membrane and stroma, blood vessel penetration, and metastasis. They have more recently been implicated in primary and metastatic tumor growth and angiogenesis, and they may even have a role in tumor promotion. This review outlines our current understanding of the MMP family, including the association of particular MMPs with malignant phenotypes and the role of MMPs in specific steps of the metastatic cascade. As scientific understanding of the MMPs has advanced, therapeutic strategies that capitalize on blocking the enzymes have rapidly developed. The preclinical and clinical evolution of the synthetic MMP inhibitors (MMPIs) is also examined, with the discussion encompassing important methodologic issues associated with determining clinical efficacy of MMPIs and other novel therapeutic agents.

Abstract
OBJECTIVE Carcinomas of the colon and rectum are the third leading cause of cancer-related deaths. Although advances in the surgical treatment of primary colorectal cancers have lead to improvements in patient survival at early tumor stages, treatment of more progressive cancers has not resulted in dramatic improvements in patient survival. However, the selection of patient subgroups based on their prognosis and other characteristics could result in improved outcomes from adjuvant therapies in patients with Dukes B and C carcinomas. METHODS The authors reviewed the available data on the value of cell surface molecules in assessing the prognosis of colorectal carcinomas, paying specific attention to the evaluation of statistical analysis and multivariate procedures. RESULTS Cell surface molecules have been identified on colorectal carcinoma cells whose expression appears to be related to malignant transformation, tumor progression, or patient prognosis. Among these cell surface molecules, various cell adhesion molecules, growth factor receptors, proteinases, and their receptors and inhibitors have been identified as potentially useful prognostic markers. CONCLUSIONS Although data exist on the prognostic values of certain cell surface markers, the use of multivariate analysis for the identification of valuable prognostic factors remains uncommon. Using reproducible and standardized multivariate analysis procedures, new tumor markers should be carefully examined for their biologic and prognostic relevance before being considered as potentially useful in the management of colorectal cancers.

Abstract
Invasive growth of malignant cells, particularly carcinoma cells, induces host reaction within and around tumor tissue. Representatives of them are desmoplasia, angiogenesis and immune reactions. Desmoplasia, a process of fibrosis, is induced by activation of fibroblasts with increased production of matrix proteins and matrix degrading enzymes. Angiogenesis is prerequisite for the growth of solid tumor. Inhibition of this is now a target of cancer therapy. The present author has proposed a concept that tumor vessels are composed of nutrient vessels and immune/inflammatory vessels. The latter is similar to venules in inflammatory lesions expressing the cell adhesion molecules to facilitate the transmigration of inflammatory cells to the tissue. In colon cancer, venules distributed along the invasive margin correspond to these vessels, which express E-, and P-selectins, and ICAM-1. These venules are considered to be an entry site of immune/inflammatory cells to cancer tissue. To further analyze immune mechanism, the present authors have confirmed that macrophages distributed along the invasive margin of colon cancer express costimulatory molecules B7.1/B7.2, which are required for the proliferation of T-cells. T-cells were co-localized with these cells. Clinicopathologic analysis confirmed that CD8+ T-cells distributed within cancer cell nest (intraepithelial) have the most significant impact on the patients' survival in colorectal cancer. These data suggest that various host reactions take place in the stroma of cancer tissue, which modulate the biologic behavior of cancer.

Abstract
Gastric cancer is classified into intestinal and diffuse types, which exhibit different biological behavior. Urokinase-type plasminogen activator (uPA), its receptor (uPAR) and matrix metalloproteinases (MMPs)-1 and -9 are considered to play important roles in cancer invasion and metastasis. We have already suggested a functional duality of these matrix-degrading enzymes/factors; they may also be involved in the matrix turnover (remodeling) or host immune/inflammatory reactions as far as they are expressed by host cells. We performed a retrospective study on the immuno-histochemical expression of these enzymes/factors in surgical specimens from patients with gastric cancer, including 26 with the diffuse and 78 with the intestinal type. We also evaluated macrophages since they are major sources of uPAR. The positivity rate for uPA in cancer cells was significantly lower in diffuse-type than in intestinal-type. Stromal expression was seen mainly along the invasive margin (tumor-host interface). The degree of stromal expression of uPAR and MMP-9 and the macrophage number were markedly decreased in diffuse-type compared with intestinal-type. Stromal expression of uPAR and macrophage number in intestinal-type were higher in patients without liver metastasis than in patients with liver metastasis, while uPA expression in cancer cells was more pronounced in patients with liver metastasis. Studies using frozen sections revealed that the expression of MMP-1, restricted to the stromal area, was more decreased in diffuse-type (18 patients) than in intestinal-type (21 patients). Our results show that the in situ expression of matrix-degrading enzymes/factors in gastric cancer is significantly more diminished in diffuse-type than in intestinal-type, suggesting a multifunctional aspect of the matrix-degradation process in cancer tissue.

Abstract
AIMS/BACKGROUND Expression of urokinase-type plasminogen activator receptor (uPAR) was studied in 25 hepatocellular carcinomas (HCCs) and seven cholangiocellular carcinomas (CCCs) by immunohistochemistry. METHODS AND RESULTS uPAR was expressed mostly by host cells distributed along the tumour-host interface in all cases of HCC and CCC, and its expression was higher in CCC. These uPAR-positive cells were identified as macrophages by observation of serial sections stained for CD68, a marker for macrophages. Cancer cells were positive for uPAR in only one case of poorly differentiated HCC with sarcomatous changes and in three cases of CCC. Hepatocellular carcinomas were classified into two types: those with a fibrous capsule (expansive type) and those without a fibrous capsule (invasive type). Invasive-type HCCs showed more prominent expression of uPAR by macrophages than expansive HCCs (p<0.001), to approximately the same degree as that of CCC. Extrahepatic metastasis was observed in two of 16 expansive HCCs, five of nine invasive HCCs and six of seven CCCs. CONCLUSIONS Our findings suggest that uPAR expression mainly by macrophages is associated with invasive growth of cancer cells into the surrounding tissue in primary carcinoma of the liver.

Abstract
Cancers are characterized by invasive growth and distant metastasis. Cancer cells not only destroy the pre-existing extracellular matrix, but cancer invasion per se usually induces new matrix formation by activation of stromal cells; that is, desmoplastic reaction. This process includes both matrix production and degradation; that is, the remodeling process. The similarity between desmoplastic reactions in cancer stroma and the wound healing process has already been pointed out, and it has been well documented that matrix-degrading processes are actively involved in the would healing process. A recent study revealed that most matrix-degrading enzymes, generally considered to be one of the main mechanisms of cancer invasion and metastasis, are originated from stromal cells. Based on these preconditions, the present review postulates that the abundant expression of matrix-degrading enzymes by fibroblasts, coupled with the abundant expression of type I procollagen, is involved in the matrix remodeling processes occurring in cancer stroma; that is, the mechanism similar to the wound healing process. Next, macrophages distributed along the invasive margin are known to express matrix-degrading enzymes/factors. Data from past studies of colon carcinoma indicate that the tissue expression of matrix metalloproteinase-9 and urokinase-type plasminogen activator receptor is inversely associated with simultaneous liver metastasis and infiltrating growth pattern. Previous clinicopathologic data have indicated that immune/inflammatory cells are one of the factors for a favorable prognosis. This suggests that the expression of matrix-degrading enzymes/factors by these host cells may be involved in host immune/inflammatory reactions, and that the net function of these cells can be defensive towards the host. Data from past studies of colon carcinoma on the expression of the intercellular adhesion molecule-1 suggest that the interaction between macrophages, lymphocytes, and the phenotypes of venules distributed along the invasive margin, further support the pro-inflammatory milleu there. Therefore, the matrix degradation process in cancer tissue is multifunctional: besides the involvement in cancer invasion and metastasis, the matrix degradation process is also involved in the tissue remodeling process and in the immune/inflammatory reaction occurring in the stroma.

Abstract
Gangliosides have been shown to be involved in development, differentiation, oncogenesis, and cancer progression. We investigated immunohistochemical expression of globo-series gangliosides in human renal cell carcinoma (RCC) and whether their expression is related to the clinical course. The expression of globo-series gangliosides was evaluated in fresh-frozen sections of 55 primary renal tumors and 8 metastatic deposits using monoclonal antibodies RM1 and RM2, which define monosialosyl and disialosyl galactosylgloboside, respectively. The immunoreactivity of primary tumors to RM1 and/or RM2 was correlated with the clinicopathological data. Cumulative incidence of metastasis detected at initial diagnosis and during the follow-up period was significantly higher in the cases whose primary tumors were RM1/RM2-positive (RM1 and/or RM2-positive) than in the RM1/ RM2-negative (neither RM1 nor RM2-positive) cases (P < 0.05). During the follow-up period, metastasis developed in none of the RM1/RM2-negative cases which had not shown metastasis at initial diagnosis. High nuclear grade was observed only in the RM1/RM2-positive cases. The RM1/RM2-positive rate of the metastatic deposits was higher than that of the primary tumors. Furthermore, a metastatic deposit obtained from one of the cases whose primary tumors were equivocal for RM1/ RM2 was extensively stained by RM1 and RM2. These results indicate that globo-series gangliosides may be one of the biochemical indicators related to the metastatic potential of human RCC.
