Abstract
Gastric cancer (GC) is a very aggressive malignant tumor of gastrointestinal tract due to its invasive nature and early metastatic ability. Degradation of the extracellular matrix (ECM) and basement membrane (BM) barriers are essential steps in the pathology of GC. Matrix metalloproteinases (MMPs) play a crucial role in the process due to their ability to degrade and rearrange these barriers to support and facilitate tumor cell migration. Therefore, these enzymes affect early carcinogenesis, tumor development and growth as well as the invasion of cancer cells at primary and metastatic sites. The endogenous inhibitors of matrix metalloproteinases (TIMPs) inhibit the active forms of MMPs and regulate the processes of their activation. The imbalance between MMPs and TIMPs may facilitate the progression of neoplastic cells. The enhanced levels of various MMPs and TIMPs have been observed in the tissue, plasma and serum of patients with many types of tumor, including gastric cancer. Moreover, levels of MMPs and TIMPs in the tissues as well as in the blood of GC patients correlated with tumor stage, depth of tumor invasion, presence of nodal and distant metastases. Selected MMPs and their tissue inhibitors were proved to be independent prognostic factors for GC patients' survival. However, further studies concerning the role of MMPs and their inhibitors in tumor biology are necessary.

Abstract
TIMP-1 is well known to be capable of inhibiting apoptosis. Elevated levels of TIMP-1 in tumor tissue have been shown to be strongly associated with a poor response to chemotherapy. In this study, using conventional cytotoxic drugs commonly used in the treatment of breast cancer, we investigated how TIMP-1 influenced the efficacy using breast cell lines. Our data demonstrated that overexpression of TIMP-1 could significantly decrease the sensitivity of MDA-435 breast cancer cells to epirubicin and paclitaxel. TIMP-1 can potently activate phosphatidylinositol 3-kinase (PI3K)/Akt and nuclear factor-kappaB (NF-кB) signaling. Furthermore, the TIMP-1-induced attenuation of the effect of epirubicin and paclitaxel was reversed by the PI3K/Akt chemical inhibitor LY294002 and the NF-кB inhibitor pyrrolidine dithiocarbamate (PDTC), showing that the PI3K/Akt and NF-кB signaling pathway was involved in the TIMP-1-induced effect on chemoresistance. Taken together, our results indicate that TIMP-1 decreased chemosensitivity through the PI3K/Akt/NF-кB signal transduction pathway in MDA-435 breast cancer cells.

Abstract
Altered expression of phosphorylated signal transducer and activator of transcription 3 (pSTAT3) and suppressor of cytokine signaling 3 (SOCS3) has been implicated in various types of human cancers. However, the clinical role of pSTAT3 and SOCS3 in hepatocellular carcinoma (HCC) is not well established. Immunohistochemical analysis of pSTAT3, SOCS3, Ki67 and VEGF expression was performed on tissue microarrays from 138 HCC patients. The expression of STAT3 mRNA was further detected by in situ hybridization. The association of pSTAT3 and SOCS3 expression with clinicopathological factors and patient survival was analyzed. Altered expression of pSTAT3 and SOCS3 was observed in HCC specimens, compared to adjacent non-tumor tissue. Increased expression of pSTAT3 was correlated with large tumor size, higher clinical stage, Ki67 and VEGF expression, as well as poor patient survival. Decreased expression of SOCS3 was correlated with the expression of Ki67, VEGF and pSTAT3, and poor patient survival. Moreover, the expression of pSTAT3 was conversely correlated with SOCS3 expression in HCC. Our results indicate that deregulated expression of pSTAT3 and SOCS3 may play roles in the development and progression of HCC. PSTAT3 and SOCS3 should be further evaluated as potential novel biomarkers for HCC prognosis.

Abstract
AIM: To investigate the clinical significance of the expression of Twist1, MMP-2 and MMP-9 proteins in colorectal cancer.
METHODS: The expression of Twist1, MMP-2 and MMP-9 proteins was examined on tissue chips containing 92 colorectal cancer samples by immunohistochemistry.
RESULTS: The positive rates of Twist1, MMP-2 and MMP-9 protein expression in colorectal cancer were 64.1%, 66.3% and 67.4%, respectively. High expression of Twist1 was positively correlated with lymph node metastasis and TNM stage (both P < 0.05) but inversely with patient's overall survival and relapse-free survival (P < 0.05 and 0.01, respectively). The expression of MMP-2 and MMP-9 was significantly correlated with lymph node metastasis (both P < 0.01). A positive correlation was also found between MMP-9 expression and tumor size (P < 0.01). The expression of Twist1 was positively correlated with that of MMP-9 (P < 0.05), but not with that of MMP-2 (P > 0.05).
CONCLUSION: The expression of Twist1, MMP-2 and MMP-9 plays an important role in tumor invasion and metastasis in colorectal cancer. The expression of MMP-9 might be partly regulated by Twist1.

Abstract
Introduction Tumors that express estrogen receptor alpha (ERα+) comprise 75% of breast cancers in women. While treatments directed against this receptor have successfully lowered mortality rates, many primary tumors initially or later exhibit resistance. The paucity of murine models of this "luminal" tumor subtype has hindered studies of factors that promote their pathogenesis and modulate responsiveness to estrogen-directed therapeutics. Since epidemiologic studies closely link prolactin and the development of ERα+ tumors in women, we examined characteristics of the aggressive ERα+ and ERα- carcinomas which develop in response to mammary prolactin in a murine transgenic model (neu-related lipocalin- prolactin (NRL-PRL)). To evaluate their relationship to clinical tumors, we determined phenotypic relationships among these carcinomas, other murine models of breast cancer, and features of luminal tumors in women. Methods We examined a panel of prolactin-induced tumors for characteristics relevant to clinical tumors: histotype, ERα/progesterone receptor (PR) expression and estrogen responsiveness, Activating Protein 1 (AP-1) components, and phosphorylation of signal transducer and activator of transcription 5 (Stat5), extracellular signal regulated kinase (ERK) 1/2 and AKT. We compared levels of transcripts in the ERα-associated "luminal" signature that defines this subtype of tumors in women and transcripts enriched in various mammary epithelial lineages to other well-studied genetically modified murine models of breast cancer. Finally, we used microarray analyses to compare prolactin-induced ERα+ and ERα- tumors, and examined responsiveness to estrogen and the anti-estrogen, Faslodex, in vivo. Results Prolactin-induced carcinomas were markedly diverse with respect to histotype, ERα/PR expression, and activated signaling cascades. They constituted a heterogeneous, but distinct group of murine mammary tumors, with molecular features of the luminal subtype of human breast cancer. In contrast to morphologically normal and hyperplastic structures in NRL-PRL females, carcinomas were insensitive to ERα-mediated signals. These tumors were distinct from mouse mammary tumor virus (MMTV)-neu tumors, and contained elevated transcripts for factors associated with luminal/alveolar expansion and differentiation, suggesting that they arose from physiologic targets of prolactin. These features were shared by ERα+ and ERα- tumors, suggesting a common origin, although the former exhibited transcript profiles reflecting greater differentiation. Conclusions Our studies demonstrate that prolactin can promote diverse carcinomas in mice, many of which resemble luminal breast cancers, providing a novel experimental model to examine the pathogenesis, progression and treatment responsiveness of this tumor subtype.

Abstract
BACKGROUND Retinoid receptor-induced gene-1 (RRIG1) is a novel gene that has been lost in several types of human cancers. The aim of this study was to determine whether RRIG1 plays a role in breast cancer, such as in the suppression of breast cancer cell growth and invasion. METHODS Immunohistochemistry was used to detect RRIG1 expression in breast tissue specimens. Gene transfection was used to restore or knock down RRIG1 expression in breast cancer cell lines for analysis of cell viability, colony formation, and migration/invasion potential. Reverse-transcription polymerase chain reaction and western blot assays were used to detect the changes in gene expression. The RhoA activation assay was used to assess RRIG1-induced inhibition of RhoA activity. RESULTS The immunohistochemical data showed that RRIG1 expression was reduced in breast cancer tissues compared with normal and atypical hyperplastic breast tissues. RRIG1 expression was inversely correlated with lymph node metastasis of breast cancer but was not associated with the status of hormone receptors, such as estrogen receptor, progesterone receptor, or HER2. Furthermore, restoration of RRIG1 expression inhibited proliferation, colony formation, migration, and invasion of breast cancer cells. Expression of RRIG1 also reduced phosphorylated Erk1/2 and Akt levels; c-Jun, MMP9, and Akt expressions; and RhoA activity. In contrast, knockdown of RRIG1 expression promoted breast cancer cell proliferation, colony formation, migration, and invasion potential. CONCLUSION The data from the current study indicated that RRIG1 expression was reduced or lost in breast cancer and that restoration of RRIG1 expression suppressed breast cancer cell growth and invasion capacity. Future studies will determine the underlying molecular mechanisms and define RRIG1 as a tumor-suppressor gene in breast cancer.

Biomarkers of extracellular matrix metabolism (MMP-9 and TIMP-1) and risk of stroke, myocardial infarction, and cause-specific mortality: cohort study. PLoS One 2011; 6:e16185.

Abstract
Objective Turnover of the extracellular matrix in all solid organs is governed mainly by a balance between the degrading matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs). An altered extracellular matrix metabolism has been implicated in a variety of diseases. We investigated relations of serum levels of MMP-9 and TIMP-1 to mortality risk from an etiological perspective. Design The prospective Uppsala Longitudinal Study of Adult Men (ULSAM) cohort, followed from 1991–1995 for up to 18.1 years. A random population-based sample of 1,082 71-year-old men, no loss to follow-up. Endpoints were all-cause (n = 628), cardiovascular (n = 230), non-cardiovascular (n = 398) and cancer mortality (n = 178), and fatal or non-fatal myocardial infarction (n = 138) or stroke (n = 163). Results Serum MMP-9 and TIMP-1 levels were associated with risk of all-cause mortality (Cox proportional hazard ratio [HR] per standard deviation 1.10, 95% confidence interval [CI] 1.03–1.19; and 1.11, 1.02–1.20; respectively). TIMP-1 levels were mainly related to risks of cardiovascular mortality and stroke (HR per standard deviation 1.22, 95% CI 1.09–1.37; and 1.18, 1.04–1.35; respectively). All relations except those of TIMP-1 to stroke risk were attenuated by adjustment for cardiovascular disease risk factors. Relations in a subsample without cardiovascular disease or cancer were similar to those in the total sample. Conclusion In this community-based cohort of elderly men, serum MMP-9 and TIMP-1 levels were related to mortality risk. An altered extracellular matrix metabolism may be involved in several detrimental pathways, and circulating MMP-9 or TIMP-1 levels may be relevant markers thereof.

Abstract
BACKGROUND Different microRNAs have been shown to have oncogenic and tumor-suppressive functions in human cancers. Detection of their expression may lead to identifying novel markers for breast cancer. METHODS The authors detected miR-340 expression in 4 human breast cell lines and then focused on its role in regulation of tumor cell growth, migration, and invasion and target gene expression. They then analyzed miR-340 expression in benign and cancerous breast tissue specimens. RESULTS Endogenous miR-340 expression was down-regulated in the more aggressive breast cancer cell lines, which was confirmed in breast cancer tissue specimens by using quantitative real-time polymerase chain reaction. Further studies showed that induction of miR-340 expression was able to suppress tumor cell migration and invasion, whereas knockdown of miR-340 expression induced breast cancer cell migration and invasion. At the gene level, the authors identified c-Met as a direct miR-340 target to mediate cell migration and invasion through regulation of MMP-2 and MMP-9 expression. Ex vivo, loss of miR-340 expression was associated with lymph node metastasis, high tumor histological grade, clinical stage, and shorter overall survival of breast cancer as well as increased c-Met expression in breast cancer tissue specimens. CONCLUSIONS miR-340 may play an important role in breast cancer progression, suggesting that miR-340 should be further evaluated as a novel biomarker for breast cancer metastasis and prognosis, and potentially a therapeutic target.

Abstract
AIM: To examine the effects of treatment with oxymatrine (OM) on MMP-2 expression and cell invasion in human pancreatic carcinoma cell line SW1990.
METHODS: Cultured SW1990 cells were randomly divided into two groups: control group and OM group. The OM group was further divided into three subgroups, which were treated with three different doses of OM (1, 2 and 4 g/L). MMP-2 expression in SW1990 cells was analyzed by real-time RT-PCR. Cell invasion, migration and proliferation were measured by scratch assay, transwell invasion assay and MTT assay, respectively.
RESULTS: The expression levels of MMP-2 mRNA in SW1990 cells in the three OM subgroups were significantly lower than that in the control group (0.53 ± 0.03, 0.42 ± 0.02, 0.29 ± 0.03 vs 0.70 ± 0.03, all P < 0.05). The invasion of cells in the three OM subgroups was markedly lower than that in the control group (325 ± 64.43, 206 ± 84.76, 124 ± 46.78 vs 498 ± 78.54, all P < 0.05). The mobility of cells in the three OM subgroups was also significantly lower than that in the control group (385.0 ± 58.9, 287.0 ± 79.8, 186.0 ± 60.9 vs 586.0 ± 85.8, all P < 0.05).
CONCLUSION: OM reduces the invasion of SW1990 cells possibly by inhibiting the expression of MMP-2.

Abstract
Background As cell-free circulating DNA exists predominantly as mono- and oligonucleosomes, the focus of the current study was to examine the interplay of circulating nucleosomes, DNA, proteases and caspases in blood of patients with benign and malignant breast diseases. Methods The concentrations of cell-free DNA and nucleosomes as well as the protease and caspase activities were measured in serum of patients with benign breast disease (n = 20), primary breast cancer (M0, n = 31), metastatic breast cancer (M1, n = 32), and healthy individuals (n = 28) by PicoGreen, Cell Death Detection ELISA, Protease Fluorescent Detection Kit and Caspase-Glo®3/7 Assay, respectively. Results Patients with benign and malignant tumors had significantly higher levels of circulating nucleic acids in their blood than healthy individuals (p = 0.001, p = 0.0001), whereas these levels could not discriminate between benign and malignant lesions. Our analyses of all serum samples revealed significant correlations of circulating nucleosome with DNA concentrations (p = 0.001), nucleosome concentrations with caspase activities (p = 0.008), and caspase with protease activities (p = 0.0001). High serum levels of protease and caspase activities associated with advanced tumor stages (p = 0.009). Patients with lymph node-positive breast cancer had significantly higher nucleosome levels in their blood than node-negative patients (p = 0.004). The presence of distant metastases associated with a significant increase in serum nucleosome (p = 0.01) and DNA levels (p = 0.04), and protease activities (p = 0.008). Conclusion Our findings demonstrate that high circulating nucleic acid concentrations in blood are no indicators of a malignant breast tumor. However, the observed changes in apoptosis-related deregulation of proteolytic activities along with the elevated serum levels of nucleosomes and DNA in blood are linked to breast cancer progression.

Abstract
Organization into polarized three-dimensional structures defines whether epithelial cells are normal or malignant. In a model of morphogenesis, we show that inhibiting key signaling pathways in human breast cancer cells leads to "phenotypic reversion" of the malignant cells. Using architecture as an endpoint, we report that, in all cases, signaling through Raf/MEK/ERK disrupted tissue polarity via matrix metalloproteinase9 (MMP9) activity. Induction of Raf or activation of an engineered, functionally inducible MMP9 in nonmalignant cells led to loss of tissue polarity, and reinitiated proliferation. Conversely, inhibition of Raf or MMP9 with small molecule inhibitors or shRNAs restored the ability of cancer cells to form polarized quiescent structures. Silencing MMP9 expression also reduced tumor growth dramatically in a murine xenograft model. LC-MS/MS analysis comparing conditioned medium from nonmalignant cells with or without active MMP9 revealed laminin 111 (LM1) as an important target of MMP9. LM1 has been implicated in acinar morphogenesis; thus, its degradation by MMP9 provides a mechanism for loss of tissue polarity and reinitiation of growth associated with MMP9 activity. These findings underscore the importance of the dynamic reciprocity between the extracellular matrix integrity, tissue polarity, and Raf/MEK/ERK and MMP9 activities, providing an axis for either tissue homeostasis or malignant progression.

Abstract
Invasive aspergillosis increases in chronic immunosuppressive diseases such as cancer. There is little information about the mechanisms by which Aspergillus infection affects the immune regulation and microenvironment of cancer cells. Hence, this study was aimed at investigating the effect of invasive aspergillosis on immunosurveillance, metastasis, and prognosis of cancer in tumor-bearing mice. After implantation of mouse mammary tumor in BALB/c mice, they were infected with Aspergillus conidia intravenously. For comparison, groups of mice were experimentally infected with Aspergillus conidia or implanted with tumor cells separately. Seven days after Aspergillus infection, the serum levels of tissue inhibitor of metalloproteinase-1 (TIMP-1) were measured by ELISA, and subsequently regulatory T lymphocytes were analyzed by flow cytometry. The survival of animals and mean tumor size were then determined. Our results indicated that tumor sizes in mice increased significantly after infection with Aspergillus conidia. Moreover, invasive aspergillosis enhanced the population of regulatory lymphocytes and level of TIMP-1. This study supports the idea that massive Aspergillus infection could stimulate tumor growth and increases the possibility of a bad prognosis. As a result, treatment of Aspergillus infection could be considered an important issue for efficient cancer therapy.

Abstract
Sex steroids, particularly estrogen and progesterone, promote normal breast tissue growth and differentiation. Prolonged exposure of estrogen and/or progesterone is considered a risk factor for breast cancer carcinogenesis, and the effects of sex steroids on breast cancer metastasis are controversial. Emerging evidence indicates that sex steroids regulate breast cancer metastatic processes via nongenomic and genomic mechanisms. Through the regulation of actin-binding proteins estrogen and progesterone rapidly provoke actin cytoskeleton reorganization in breast cancer cells, leading to formation of membrane structures facilitating breast cancer cell migration and invasion. In addition, steroid receptors interact and trans-activate receptor tyrosine kinases (including epidermal growth factor receptor and insulin-like growth factor receptor), resulting in growth factor-like effects that promote cancer cell invasive behavior. Moreover, sex steroids regulate the expression of metastasis-associated molecules, such as E-cadherin, matrix metalloproteinases, growth factors, chemokines and their receptors, leading to epithelial-to-mesenchymal-like transition. However, there is also evidence that sex steroids and their receptors protect against breast cancer cell invasiveness through distinct mechanisms. Here, we present an overview of the currently identified actions of sex steroids on breast cancer metastasis and their potential clinical implications.

Abstract
BACKGROUND TACE/ADAM17 is a transmembranous protease that cleaves membrane-bound growth factors like EGFR ligands. TACE-dependent proteolysis is regulated by its inhibitor, tissue inhibitor of metalloproteinases 3 (TIMP3). This study analyses the role of TACE and TIMP3 mRNA expression in squamous cell carcinomas of the head and neck (HNSCCs). METHODS We analysed TACE and TIMP3 mRNA expression in HNSCCs from 106 patients by RNA in situ hybridisation. RESULTS TACE mRNA was upregulated in HNSCCs compared with dysplastic (P<0.05) and normal epithelia (P<0.001), with strong hybridisation signals in 21.9% of invasive tumour tissues and 4.5% of dysplasia. Elevated mRNA levels were accompanied by increased amounts of TACE protein in HNSCCs. TIMP3 mRNA expression in HNSCC-associated stroma was significantly higher than in the stroma adjacent to dysplastic or normal epithelia. Expression of TACE mRNA in HNSCCs was associated with tumour stage (P=0.019) and regional lymph node metastasis (P=0.009). Furthermore, levels of TACE mRNA in HNSCCs correlated with the expression of TIMP3 mRNA in HNSCC-associated stroma. Concomitantly, patients expressing high levels of TACE and TIMP3 mRNA showed significantly reduced overall survival compared with those with low mRNA levels. CONCLUSION Our results indicate an important role of TACE and TIMP3 during development and progression of HNSCCs.

Abstract
Background MicroRNAs (miRNAs) play an important role in the regulation of cell growth, differentiation, apoptosis, and carcinogenesis. Detection of their expression may lead to identifying novel markers for breast cancer. Methods We profiled miRNA expression in three breast cancer cell lines (MCF-7, MDA-MB-231, and MDA-MB-468) and then focused on one miRNA, miR-339-5p, for its role in regulation of tumor cell growth, migration, and invasion and target gene expression. We then analyzed miR-339-5p expression in benign and cancerous breast tissue specimens. Results A number of miRNAs were differentially expressed in these cancer cell lines. Real-time PCR indicated that miR-339-5p expression was downregulated in the aggressive cell lines MDA-MB-468 and MDA-MB-231 and in breast cancer tissues compared with benign tissues. Transfection of miR-339-5p oligonucleotides reduced cancer cell growth only slightly but significantly decreased tumor cell migration and invasion capacity compared with controls. Real-time PCR analysis showed that BCL-6, a potential target gene of miR-339-5p, was downregulated in MDA-MB-231 cells by miR-339-5p transfection. Furthermore, the reduced miR-339-5p expression was associated with an increase in metastasis to lymph nodes and with high clinical stages. Kaplan-Meier analyses found that the patients with miR-339-5p expression had better overall and relapse-free survivals compared with those without miR-339-5p expression. Cox proportional hazards analyses showed that miR-339-5p expression was an independent prognostic factor for breast cancer patients. Conclusions MiR-339-5p may play an important role in breast cancer progression, suggesting that miR-339-5p should be further evaluated as a biomarker for predicting the survival of breast cancer patients.

Abstract
The aim of this study was to evaluate the effects of ulinastatin (UTI) and cyclophosphamide (CTX) as mono therapies and as combination therapy on the growth of mouse xenograft breast tumours. MCF-7 breast cancer cells were xenografted into 48 nu/nu nude mice in order to construct a breast cancer xenograft nude mouse model; mice were then untreated (control), or treated with CTX 0.1 g/kg every other day, UTI once a day at 25 000 U (low), 50 000 U (medium) or 100 000 U (high), or CTX + UTI (low), CTX + UTI (medium) or CTX + UTI (high) (n = 6 mice/group). Compared with controls, mice in each drug-treated group had a significantly reduced tumour weight, and protein and mRNA levels of CXC chemokine receptor 4 and matrix metalloproteinase-9 in both the UTI (low, medium and high doses) and CTX groups were significantly reduced, while levels in the UTI (low, medium and high doses) + CTX combination groups were significantly reduced compared with the CTX group and the UTI (low, medium, high) groups. Thus, both UTI and CTX can significantly inhibit xenograft tumours, and the UTI + CTX combination exhibited an additive effect that was superior to both CTX and UTI monotherapy.

Abstract
Interaction between cell surface integrin receptors with extracellular matrix (ECM) plays an important role in cell survival, proliferation, and migration including tumor development and invasion. Binding of ECM to integrins initiates intracellular signaling cascades, modulating expression and activity of different matrix metalloproteinases (MMPs) which is important in ECM degradation. The present study investigates fibronectin-integrin-mediated signaling and thereby modulation of MMPs expression and activity in human breast cancer cell line, MDA-MB-231. Culture of MDA-MB-231 cells on fibronectin (FN) induced expression and activity of pro-matrixmetalloproteinase-9 (MMP-9). Appreciable reduction of FN-induced pro-MMP-9 activity was observed in anti-α5 antibody treated cells. Inhibitor studies revealed that inhibitors of phosphatidyl inositiol-3-kinase (PI-3K), and nuclear factor kappa B (NF-κB) inhibited FN-induced pro-MMP-9 activity. FN increased tyrosine phosphorylation of focal adhesion kinase (FAK), integrin linked kinase (ILK), and PI-3K in MDA-MB-231 cells. FN-induced the transactivation of MMP-9 promoter by enhancing DNA binding activity of NF-κB and Sp1. Wound healing assay showed faster migration of MDA-MB-231cells grown on fibronectin-coated as surface as compared to control. Our findings indicated that culture of MDA-MB-231 on fibronectin perhaps send signals via fibronectin-integrin-mediated signaling pathways recruiting FAK, PI-3K, ILK, NF-κB, and modulate expression and activation of pro-MMP-9. These observations may enrich fundamental aspects of cancer biology especially role of α5β1 integrin in regulation of MMPs expression and activity.

Abstract
In addition to tumor invasion and angiogenesis, matrix metalloproteinase (MMP)9 also contributes to carcinogenesis and tumor growth. Genetic variation that may influence MMP9 expression was evaluated among participants of the Shanghai Breast Cancer Genetics Study (SBCGS) for associations with breast cancer susceptibility. In stage 1, 11 MMP9 single nucleotide polymorphisms (SNPs) were genotyped by the Affymetrix Targeted Genotyping System and/or the Affymetrix Genome-Wide Human SNP Array 6.0 among 4,227 SBCGS participants. One SNP was further genotyped using the Sequenom iPLEX MassARRAY platform among an additional 6,270 SBCGS participants. Associations with breast cancer risk were evaluated by odds ratios (OR) and 95% confidence intervals (CI) from logistic regression models that included adjustment for age, education, and genotyping stage when appropriate. In Stage 1, rare allele homozygotes for a promoter SNP (rs3918241) or a non-synonymous SNP (rs2274756, R668Q) tended to occur more frequently among breast cancer cases (P value = 0.116 and 0.056, respectively). Given their high linkage disequilibrium (D' = 1.0, r (2) = 0.97), one (rs3918241) was selected for additional analysis. An association with breast cancer risk was not supported by additional Stage 2 genotyping. In combined analysis, no elevated risk of breast cancer among homozygotes was found (OR: 1.2, 95% CI: 0.8-1.8). Common genetic variation in MMP9 was not found to be significantly associated with breast cancer susceptibility among participants of the Shanghai Breast Cancer Genetics Study.

Abstract
OBJECTIVE To investigate the influence of serum-free medium (SFM) supplemented with epidermal growth factor and basic fibroblast growth factor compared with conventional serum-containing medium (SCM) on the phenotype of organotypic primary spheroids from seven gliomas. METHODS Paraffin sections of the original surgical specimens, primary glioma spheroids, and U87 derived spheroids were stained immunohistochemically with the stem cell markers CD133, podoplanin, Sox2, Bmi-1, and nestin; the endothelial cell markers CD31, CD34, and Von Willebrand Factor (VWF); the chemosensitivity markers P-glycoprotein and tissue inhibitor of metalloproteinases-1 (TIMP-1); and glial fibrillary acidic protein, neural cell adhesion molecule CD56, and the proliferation marker Ki67. RESULTS Scoring of the immunohistochemical stainings showed that the expression of CD133 and all other markers included was preserved in primary spheroids, confirming the in vivo-like nature of these spheroids. Spheroids in SFM better mimicked the in vivo phenotype with significantly more CD133, CD34, VWF, P-glycoprotein, TIMP-1, and Ki67 compared with SCM. CONCLUSION In this first study of the influence of SFM on primary glioma spheroids, the conditions favored an in vivo-like phenotype with increased expression of CD133. More vascular structures were found in SFM, suggesting that the close relationship between blood vessels and tumor stem-like cells was better preserved in this medium.

Abstract
Application of camptothecin (CPT) is hampered due to its extreme water insolubility and unpredictable side effects. Therefore, it is essential to establish an efficient and safe protocol for the administration of camptothecin against tumor growth and metastasis. Here, we encapsulated camptothecin with N-trimethyl chitosan (CPT-TMC) and tested it on BALB/c mice subcutaneously injected with murine hepatocellular carcinoma cells at the hindlimb feet pad. CPT-TMC effectively inhibited tumor growth and lymphatic metastasis, prolonged survival time, yet without apparent toxic effects. Thus, CPT-TMC may provide a novel and effective therapeutic strategy against human advanced hepatic cancer without conspicuous systemic toxic effects.

Abstract
The function of macrophage inhibitory cytokine-1 (MIC-1) in cancer remains controversial, and its signaling pathways remain poorly understood. In this study, we demonstrate that MIC-1 induces the transactivation of EGFR, ErbB2, and ErbB3 through the activation of c-Src in SK-BR-3 breast cells. MIC-1 induced significant phosphorylation of EGFR at Tyr845, ErbB2 at Tyr877, and ErbB3 at Tyr1289 as well as Akt and p38, Erk1/2, and JNK mitogen-activated protein kinases (MAPKs). Treatment of SK-BR-3 cells with MIC-1 increased the phosphorylation level of Src at Tyr416, and induced invasiveness of those cells. Inhibition of c-Src activity resulted in the complete abolition of MIC-1-induced phosphorylation of the EGFR, ErbB2, and ErbB3, as well as invasiveness and matrix metalloproteinase (MMP)-9 expression in SK-BR-3 cells. Collectively, these results show that MIC-1 may participate in the malignant progression of certain cancer cells through the activation of c-Src, which in turn may transactivate ErbB-family receptors.

Abstract
In the current study, we have examined the efficacy of a Src/Abl kinase inhibitor SKI-606 (Bosutinib) for its effect on prostate cancer growth and skeletal metastasis. Treatment of highly invasive human prostate cancer cells PC-3 and DU-145 with different doses of SKI-606 decreased Src activation, cell proliferation, migration, and invasion as determined by Matrigel Boyden chamber invasion assay. For in vivo studies, PC-3 cells were inoculated through s.c. or i.t. route into male BALB/c nu/nu or Fox Chase severe combined immunodeficient mice, respectively. Experimental animals treated with SKI-606 developed tumors of a significantly smaller volume and a significant decrease (50%) in experimental skeletal lesion area. A marked increase (32%) in bone volume to tumor volume ratio was also seen by micro-computed tomography analysis of tibias from control and experimental groups of animals. Western blot analysis showed the ability of SKI-606 to significantly decrease the phosphorylation of signaling molecules (AKT, mitogen-activated protein kinase, focal adhesion kinase) and the expression of tumor progression-associated genes uPAR, MMP-2, MMP-9, N-cadherin, fibronectin, BMP-2 (bone morphogenetic protein 2), BMP-6 (bone morphogenetic protein 6), IL-8 (interleukin 8), and TGF-beta (transforming growth factor beta) in prostate cancer cells. SKI-606 is currently in clinical trials for breast cancer and chronic myelogenous leukemia. Results from these studies provide convincing evidence for evaluating its efficacy in prostate cancer patients.

Abstract
Paclitaxel (PTX) is a very effective drug in treating tumors. It disturbs microtubule dynamics and impairs the transition of cells from metaphase to anaphase in mitosis, leading to cell death by apoptosis. However, the effectiveness of PTX in cancer chemotherapy is hampered by drug resistance in some patients. Tissue inhibitor of metalloproteinase-1 (TIMP-1) is well known to be capable of inhibiting apoptosis. Elevated tumor tissue TIMP-1 levels have been significantly associated with a poor response to chemotherapy. We hypothesized that TIMP-1 could reduce the sensitivity of breast cancer cells to PTX by inhibiting apoptosis. To test this hypothesis, we first examined the effects of TIMP-1 on the apoptosis induced by PTX and investigated the effects of TIMP-1 on the expression and stability of cyclin B1 that critically regulates the metaphase to anaphase transition during mitosis in MCF-7 breast cancer cells. Our data demonstrate that TIMP-1 could significantly decrease the sensitivity of MCF-7 cells to PTX-induced apoptosis, attenuate mitotic blockage in G(2)/M, and enhance the degradation of cyclin B1. To further investigate whether the inhibitory effect of TIMP-1 on PTX-induced apoptosis is mediated by lowering levels of cyclin B1, a cyclin B1-expression plasmid was transfected into clone overexpressing TIMP-1. The levels of PTX-induced apoptosis were then analyzed. The data showed that the TIMP-1-based decrease in PTX-induced apoptosis was reversed by cyclin B1. Our data indicate that TIMP-1 can protect breast cancer cells from PTX-induced apoptosis by decreasing the stability of cyclin B1.

Abstract
PURPOSE Tumor cells, including colorectal cancer (CRC), are able to produce and release matrix metalloproteinase 9 (MMP-9) which is involved in tumor invasion and metastasis. Natural tissue inhibitors of matrix metalloproteinases (TIMPs) regulate activity of MMPs and stimulate tumor growth and malignant transformation. The aim of the present study was to compare the clinical significance of serum MMP-9 with TIMP-1 in the diagnosis of CRC patients and in the differentiation between colorectal adenoma (CA) and cancer. METHODS Serum MMP-9 and TIMP-1 were measured in 75 CRC patients, 35 CA, and 70 healthy subjects using enzyme-linked immunosorbent assay. Concentrations of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) were determined by microparticle enzyme immunoassay. RESULTS Serum levels of all proteins tested were significantly higher in CRC patients than in healthy subjects. Additionally, serum TIMP-1 was significantly higher in patients with CRC than in CA patients. Concentrations of TIMP-1 correlated with tumor stage, nodal involvement, presence of distant metastases, patients' survival, and tumor resectability. Diagnostic sensitivity of TIMP-1 was higher (61%) than those of other biomarkers (MMP-9, 55%; CEA, 39%; CA 19-9, 11%), and increased in combined use with MMP-9 (75%) or CEA (73%). The areas under receiver operating characteristic curves of TIMP-1 were larger than those of MMP-9. CONCLUSIONS Our findings suggest better usefulness of serum TIMP-1 than MMP-9 in the diagnosis of CRC, especially in the assessment of Duke's classification of tumor stage, survival of cancer patients, resectability of tumor, and in the differentiation between CA and cancer.

Abstract
BACKGROUND Recent evidence suggests that neutrophil gelatinase-associated lipocalin (NGAL) expression is induced in many types of human cancer, while detection of its complex with matrix metalloproteinase-9 (MMP-9) is correlated with cancer disease status. We aim to evaluate the serum expression of MMP-9, NGAL and their complex (MMP-9/NGAL) during the diagnostic work-up of women with breast abnormalities and investigate their correlation with disease severity. METHODS The study included 113 women with non-palpable breast lesions undergoing vacuum-assisted breast biopsy for histological diagnosis, and 30 healthy women, which served as controls. Expression levels of MMP-9, NGAL and their complex MMP-9/NGAL were determined in peripheral blood samples with immunoenzymatic assays. RESULTS Women with invasive ductal carcinoma exhibited significantly increased levels of MMP-9, NGAL and MMP-9/NGAL compared to healthy controls (MMP-9: p < 0.003, NGAL: p < 0.008 MMP-9/NGAL: p < 0.01). Significant correlations were observed between MMP-9 and NGAL serum levels and breast disease severity score (r = 0.229, p < 0.006 and r = 0.206, p < 0.01, respectively), whereas a non-significant correlation was found for their complex. MMP-9, NGAL and their complex MMP-9/NGAL levels were not correlated with either Body Mass Index (BMI) or age of patients. CONCLUSION These findings suggest that the serum measurement of MMP-9 and NGAL may be useful in non-invasively monitoring breast cancer progression, while supporting their potential role as early biomarkers of breast disease status.

Abstract
Background We have previously demonstrated that high tumor tissue levels of TIMP-1 are associated with no or limited clinical benefit from chemotherapy with CMF and anthracyclines in metastatic breast cancer patients. Here, we extend our investigations to the adjuvant setting studying outcome after adjuvant chemotherapy in premenopausal lymph node-positive patients. We hypothesize that TIMP-1 high tumors are less sensitive to chemotherapy and accordingly that high tumor tissue levels are associated with shorter survival. Methods From our original retrospectively collected tumor samples we selected a group of 525 pre-menopausal lymph node-positive patients (adjuvant treatment: CMF, 324 patients; anthracycline-based, 99 patients; no adjuvant chemotherapy, 102 patients). TIMP-1 levels were measured using ELISA in cytosolic extracts of frozen primary tumors. TIMP-1 was analyzed as a continuous variable and as a dichotomized one using the median TIMP-1 concentration as a cut point between high and low TIMP-1 groups. We analyzed the benefit of adjuvant CMF and anthracyclines in univariate and multivariable survival models; endpoints were disease-free (DFS) and overall survival (OS). Results In this selected cohort of high-risk patients, and in the subgroup of patients receiving no adjuvant therapy, TIMP-1 was not associated with prognosis. In the subgroup of patients treated with anthracyclines, when analyzed as a continuous variable we observed a tendency for increasing TIMP-1 levels to be associated with shorter DFS (multivariable analysis, HR 1.75, 95% CI 1.00-3.07, P = 0.05) and a significant association between increasing TIMP-1 and shorter OS in both univariate (HR 3.52, 95% CI 1.54-8.06, P = 0.003) and multivariable analyses (HR 4.19, 95% CI 1.67-10.51, P = 0.002). No statistically significant association between TIMP-1 and DFS was observed in the CMF-treated patients although high TIMP-1 was associated with shorter OS when analyzed as a dichotomized variable (HR 1.64, 95% CI 1.02-2.65, P = 0.04). Conclusion In the subgroup of patients receiving adjuvant chemotherapy we found an association between shorter survival after treatment in TIMP-1 high patients compared with TIMP-1 low patients, especially in patients receiving anthracycline-based therapy. This suggests that high tumor tissue levels of TIMP-1 might be associated with reduced benefit from classical adjuvant chemotherapy. Our findings should be validated in larger prospective studies.

Abstract
The matrix metalloproteinase (MMP) family of enzymes is comprised of critically important extracellular matrix remodeling proteases whose activity has been implicated in a number of key normal and pathologic processes. The latter include tumor growth, progression, and metastasis as well as the dysregulated angiogenesis that is associated with these events. As a result, these proteases have come to represent important therapeutic and diagnostic targets for the treatment and detection of human cancers. In this review, we summarize the literature that establishes these enzymes as important clinical targets, discuss the complexity surrounding their choice as such, and chronicle the development strategies and outcomes of their clinical testing to date. The status of the MMP inhibitors currently in US Food and Drug Administration approved clinical trials is presented and reviewed. We also discuss the more recent and successful targeting of this enzyme family as diagnostic and prognostic predictors of human cancer, its status, and its stage. This analysis includes a wide variety of human cancers and a number of human sample types including tissue, plasma, serum, and urine.

Abstract
Matrix metalloproteinase-9 (MMP9) has been implicated in numerous somatic illnesses, including cardiovascular disorders and cancer. Recently, MMP9 has been shown to be increasingly important in several aspects of central nervous system activity. Furthermore, a pathogenic role for this enzyme has been suggested in such neuropsychiatric disorders as schizophrenia, bipolar illness, and multiple sclerosis. In this paper, the results of biochemical and molecular-genetic studies on MMP9 that have been performed in these pathological conditions will be summarized. Furthermore, I hypothesize that the MMP9 gene, as shown by functional −1562 C/T polymorphism studies, may be mediating the relationship of neuropsychiatric illnesses (schizophrenia, bipolar mood disorder, multiple sclerosis) that are comorbid with cardiovascular disease and cancer.

Abstract
OBJECTIVE Pancreatic cancer (PC) is a malignant tumor with high mortality. Aggressive growth and metastases of PC are the result of basement membrane degradation that may be attributed to the action of matrix metalloproteinase-9 (MMP-9). The aim of the study was to determine the diagnostic and prognostic significance of the measurements of serum MMP-9 and tissue inhibitor of metalloproteinase-1 (TIMP-1) in patients with PC. METHODS The study involved 78 patients with PC, 45 with chronic pancreatitis, and 70 healthy subjects. We assayed the serum concentrations of MMP-9, TIMP-1, and classic tumor markers (carbohydrate antigen 19-9 and carcinoembryonic antigen) and defined the prognostic value and the diagnostic criteria for all the proteins tested. RESULTS In the patients with PC, the serum levels of MMP-9, TIMP-1, and the tumor markers were higher as compared with those in the patients with chronic pancreatitis and the healthy subjects. The diagnostic sensitivity and the area under the receiver operating characteristic curve for TIMP-1 were higher than for MMP-9 and the tumor markers. The elevated preoperative concentration of MMP-9 was a significant independent prognostic factor for the patients' survival. CONCLUSIONS These findings indicate a potential clinical significance of serum TIMP-1 and MMP-9 measurements in the diagnosis and prognosis of patients with PC, respectively.

Abstract
In colorectal cancer and breast cancer a high TIMP-1 level has been shown to correlate with a shorter overall patient survival and it has been suggested that TIMP-1 is involved in tumour invasion, proliferation and apoptosis in different types of cancers. TIMP-1 is known to be expressed in gliomas but whether TIMP-1 is a prognostic marker in gliomas has not previously been investigated. In the present study, the TIMP-1 expression was investigated immunohistochemically in 112 formalin-fixed paraffin embedded astrocytomas and related to tumour grade and overall patient survival by scoring the TIMP-1 immunoreactivity of both tumour cells and blood vessels. Moreover, TIMP-1 in situ hybridisation was performed on ten of the glioblastomas. In the vast majority of the tumours TIMP-1 protein was expressed in both tumour cells and blood vessels. In situ hybridisation for TIMP-1 mRNA on glioblastomas confirmed the immunohistochemical expression of TIMP-1. The percentage of TIMP-1 positive tumour cells and blood vessels as well as the staining intensity varied between tumours of the same grade, but the total staining score increased with tumour grade. The multivariate Cox regression test showed that glioblastoma patients with the lowest TIMP-1 expression had a significantly longer overall survival (HR (95% CI) = 3.2 (1.5-6.7), P = 0.004) when compared to the patients with higher TIMP-1 protein expression. In conclusion, this study showed that low TIMP-1 immunohistochemical expression predicts longer overall survival in glioblastoma patients, suggesting a role for TIMP-1 as a biomarker in glioblastoma.

Abstract
Background Cholangiocarcinoma is an aggressive tumor with a tendency for local invasion and distant metastases. Timely diagnosis is very important because surgical resection (R0) remains the only hope for a cure. However, at present, there is no available tumor marker that can differentiate cholangiocarcinoma from benign bile duct disease. Previous studies have demonstrated that matrix metalloproteinase (MMP)-7 and MMP-9 are frequently expressed in cholangiocarcinoma specimens. Methods This study was designed to determine whether the serum levels of MMP-7 and MMP-9 can discriminate cholangiocarcinoma patients from benign biliary tract disease patients in comparison to carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9). We measured the level of CEA, CA19-9, MMP-7 and MMP-9 in the serum of 44 cholangiocarcinoma and 36 benign biliary tract diseases patients. Results Among the serum levels of CEA, CA19-9, MMP-7 and MMP-9, only the serum MMP-7 level was significantly higher in the patients with cholangiocarcinoma (8.9 ± 3.43 ng/ml) compared to benign biliary tract disease patients (5.9 ± 3.03 ng/ml) (p < 0.001). An receiver operating characteristic (ROC) curve analysis revealed that the detection of the serum MMP-7 level is reasonably accurate in differentiating cholangiocarcinoma from benign biliary tract disease patients (area under curve = 0.73; 95% CI = 0.614–0.848). While the areas under the curve of the ROC curves for CEA, CA19-9 and MMP-9 were 0.63 (95% CI = 0.501–0.760), 0.63 (95% CI = 0.491–0.761) and 0.59 (95% CI = 0.455–0.722), respectively. Conclusion Serum MMP-7 appears to be a valuable diagnostic marker in the discrimination of cholangiocarcinoma from benign biliary tract disease. Further prospective studies for serum MMP-7 measurement should be carried out to further investigate the potential of this molecule as a biomarker of cholangiocarcinoma.

Abstract
Formation of multiple and scattered metastases in target organs, leading to disruption of organ functional integrity, is the death-determining step for most lethal cancers. In the clinic, elevated expression of tissue inhibitor of metalloproteinases-1 (TIMP-1) is often associated with increased aggressiveness of cancer. We demonstrated that elevated host expression of TIMP-1 leads to the promotion of scattered liver metastases in mice, associated with increased activity of cysteine proteases (CPs). This study aimed for reduction of TIMP-1-promoted experimental liver metastases of lacZ-tagged human fibrosarcoma cells by overexpression of cystatin C, a natural inhibitor of CPs, in the murine host. Although CP inhibition reduced TIMP-induced proteolytic activity, the TIMP-1-induced increase in total tumor cell burden in livers was not significantly reduced. However, overexpression of cystatin C in livers with elevated TIMP-1 led to the formation of large multicellular metastatic foci in 42% of the mice. This formation was associated with increased expression of plasminogen activators (PAs). Additional overexpression of plasminogen activator inhibitor-2 prevented the formation of macrometastatic foci as well as the TIMP-1-induced increase in total tumor cell burden. This demonstrates that PAs are crucial for the prometastatic activity of TIMP-1 and led to the assumption that patients with elevated TIMP-1 expression may benefit from an antiproteolytic treatment directed against PAs.

Abstract
BACKGROUND The COOH terminal peptide of Pro-collagen type I (PICP, also called C3) is chemotactic for endothelial melanoma and breast cancer cells. PICP induces the expression of Metalloproteinases-2 and -9, of Vascular endothelial growth factor and of the chemokine CXCL-12 receptor CXCR4 in MDA MB231 breast carcinoma cells in vitro. METHODS We used a model of xenografts in BalbC/nude mice obtaining tumors by implanting in contro-lateral subcutaneous positions MDA MB231 cells added or not with purified PICP and studied the earlier phases of tumor development, up to 48 days from implant, by histology, immunostain and in situ hybridization. RESULTS Addition of PICP promotes rapid vascularization of the tumors while does not affect mitotic and apoptotic indexes and overall tumor growth. PICP-treated, relative to control tumors, show up-modulation of Vascular endothelial factor, Metalloproteinase-9 and CXCR4, all tumor prognostic genes; they also show down-modulation of the endogenous Metalloproteinase inhibitor, reversion-inducing-cysteine-rich protein with kazal motifs, and a different pattern of modulation of Tissue Inhibitor of Metalloproteinase-2. These changes occur in absence of detectable expression of CXCL-12, up to 38 days, in control and treated tumors. CONCLUSION PICP has an early promoting effect in the acquisition by the tumors of prometastatic phenotype. PICP may be play a relevant role in the productive interactions between stroma and tumor cells by predisposing the tumor cells to respond to the proliferation stimuli ensuing the activation of signaling by engagement of CXCR4 by cytokines and by fostering their extravasion, due to the induction of increased vascular development.

Abstract
PURPOSE We have previously reported that matrix metalloproteinases MMP-2, MMP-9, and the complex MMP-9/NGAL can be detected in urine of patients with a variety of cancers including prostate and bladder carcinoma. In addition, we also detected several unidentified urinary gelatinase activities with molecular weights >125 kDa. The objective of the current study was to identify these high molecular weight (HMW) species, determine their potential as predictors of disease status, and ask whether a tumor-specific pattern existed based on urinary MMP analysis. EXPERIMENTAL DESIGN Chromatography, zymography, and mass spectrometry was used to identify HMW gelatinase species of approximately 140, 190, and >220 kDa in urine of cancer patients. To determine whether a tumor-specific pattern of appearance existed among the MMPs detected, we analyzed the urine of 189 patients with prostate or bladder cancer and controls. RESULTS The approximately 140, >220 kDa, and approximately 190 HMW gelatinase species were identified as MMP-9/tissue inhibitor of metalloproteinase 1 complex, MMP-9 dimer, and ADAMTS-7, respectively. The frequency of detection of any MMP species was significantly higher in urine from prostate and bladder cancer groups than controls. MMP-9 dimer and MMP-9 were independent predictors for distinguishing between patients with prostate and bladder cancer (P < 0.001 for each) by multivariable analysis. CONCLUSIONS This study is the first to identify a tumor-specific urinary MMP fingerprint that may noninvasively facilitate identification of cancer presence and type. This information may be of diagnostic and prognostic value in the detection and/or clinical monitoring of disease progression and therapeutic efficacy in patients with bladder or prostate cancer.

Abstract
Isoliquiritigenin (ISL, 4,2',4'-trihydroxychalcone), which is found in licorice, shallot and bean sprouts, is a potent antioxidant with anti-inflammatory and anti-carcinogenic effects. The purpose of this study was to investigate the effects of ISL treatment on the migration, invasion and adhesion characteristics of DU145 human prostate cancer cells. DU145 cells were cultured in the presence of 0-20 micromol/L ISL with or without 10 microg/L epidermal growth factor (EGF). ISL inhibited basal and EGF-induced cell migration, invasion and adhesion dose dependently. ISL decreased EGF-induced secretion of urokinase-type plasminogen activator (uPA), matrix metalloproteinase (MMP)-9, tissue inhibitor of metalloproteinase-1 (TIMP-1), and vascular endothelial growth factor (VEGF), but increased TIMP-2 secretion in a concentration-dependent manner. In addition, ISL decreased the protein levels of integrin-alpha2, intercellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM), and mRNA levels of uPA, MMP-9, VEGF, ICAM and integrin-alpha2. Furthermore, basal and EGF-induced activator protein (AP)-1 binding activity and phosphorylation of Jun N-terminal kinase (JNK), c-Jun and Akt were decreased after ISL treatment. However, phosphorylation of extracellular signal-regulated kinase (ERK)1/2 and p38 mitogen-activated protein kinase was not altered. The JNK inhibitor SP600125 inhibited basal and EGF-induced secretion of uPA, VEGF, MMP-9 and TIMP-1, as well as AP-1 DNA binding activity and cell migration. These results provide evidence for the role of ISL as a potent antimetastatic agent, which can markedly inhibit the metastatic and invasive capacity of prostate cancer cells. The inhibition of JNK/AP-1 signaling may be one of the mechanisms by which ISL inhibits cancer cell invasion and migration.

Abstract
Matrix metalloproteinases (MMP) are a family of enzymes with a myriad of functions. Lately, we have come to realize that broad-spectrum inhibition of these enzymes, as was tried unsuccessfully in multiple phase III trials in cancer patients, is likely unwise given the protumorigenic and antitumorigenic functions of various family members. Here, we used the multistage mammary tumor model MMTV-PyVT to investigate roles for either MMP7 or MMP9 in tumor progression. We found no effect of genetic ablation of MMP7 or MMP9 on the multifocal tumors that developed in the mammary glands. Lack of MMP7 also had no effect on the development of lung metastases, suggesting that MMP7 is irrelevant in this model. In contrast, MMP9 deficiency was associated with an 80% decrease in lung tumor burden. The predominant cellular source of MMP9 was myeloid cells, with neutrophils being the largest contributor in tumor-bearing lungs. Experimental metastasis assays corroborated the role of host-derived MMP9 in lung metastasis and also facilitated determination of a time frame most relevant for the MMP9-mediated effect. The lung tumors from MMP9-deficient mice showed decreased angiogenesis. Surprisingly, the antimetastatic outcome of MMP9 ablation seemed to be dependent on strain. Only mice that had genetic background derived from C57BL/6 showed reduced metastasis, whereas mice fully of the FVB/N background showed no significant effect. These strain-specific responses were also observed in a study using a highly selective pharmacologic inhibitor of MMP9 and thus suggest that responses to MMP inhibition are controlled by genetic differences.

Abstract
Improvement of the management of breast cancer patients has high priority. In this regard, prognostic stratification needs to be improved in order to ensure proper medical treatment of all patients and furthermore predictors of response to chemotherapy are urgently needed. As new treatment opportunities emerge in the future this need will continue to grow. Thus, the search for molecular markers of prognosis and prediction is ongoing. Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) has been suggested as a marker of both prognosis and response to treatment. Several studies have demonstrated the association between TIMP-1 and prognosis in breast cancer and new studies within this area have focused on the possibility of using blood samples or paraffin embedded tissue instead of tumor tissue extracts for measurements of TIMP-1. Interestingly, recent studies have investigated the association between TIMP-1 and response to treatment showing that TIMP-1 may also carry predictive information on response to treatment. In this regard, results from studies of the molecular functions of TIMP-1 point to a role of TIMP-1 in the inhibition of tumor cell apoptosis as an explanation for the clinical findings. This review gives an update on the ongoing investigation of the potential role of TIMP-1 as a tumor marker in breast cancer. Furthermore, we link the clinical findings with studies of the molecular actions of the TIMP-1 protein, raising hypotheses that may explain why TIMP-1 could play an important role in future management of breast cancer patients.
