Abstract
Combined antiretroviral therapy (cART) for HIV-1 dramatically slows disease progression among HIV+ individuals. Currently, lymphoma represents the main cause of death among HIV-1-infected patients. Detection of p17 variants (vp17s) endowed with B-cell clonogenic activity in HIV-1-seropositive patients with lymphoma suggests their possible role in lymphomagenesis. Here, we demonstrate that the clonogenic activity of vp17s is mediated by their binding to PAR1 and to PAR1-mediated EGFR transactivation through Gq protein. The entire vp17s-triggered clonogenic process is MMPs dependent. Moreover, phosphoproteomic and bioinformatic analysis highlighted the crucial role of EGFR/PI3K/Akt pathway in modulating several molecules promoting cancer progression, including RAC1, ABL1, p53, CDK1, NPM, Rb, PTP-1B, and STAT1. Finally, we show that a peptide (F1) corresponding to the vp17s functional epitope is sufficient to trigger the PAR1/EGFR/PI3K/Akt pathway and bind PAR1. Our findings suggest novel potential therapeutic targets to counteract vp17-driven lymphomagenesis in HIV+ patients.

Tumor Microenvironment in Diffuse Large B-Cell Lymphoma: Role and Prognosis. Anal Cell Pathol (Amst) 2019; 2019:8586354. [PMID: 31934533 PMCID: PMC6942707 DOI: 10.1155/2019/8586354] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Accepted: 11/06/2019] [Indexed: 12/23/2022] Open
Abstract
Diffuse large B-cell lymphoma (DLBCL) represents 30-40% of all non-Hodgkin lymphomas (NHL) and is a disease with an aggressive behavior. Because about one-third of DLBCL patients will be refractory or resistant to standard therapy, several studies focused on identification of new individual prognostic and risk stratification biomarkers and new potential therapeutic targets. In contrast to other types of cancers like carcinomas, where tumor microenvironment was widely investigated, its role in DLBCL pathogenesis and patient survival is still poorly understood, although few studies had promising results. The composition of TME and its interaction with neoplastic cells may explain the role of several genes (beta2-microglobulin gene, CD58 gene), receptor-like programmed cell death-1 (PD-1) and its ligand (PD-L1), or other cell components (Treg) in tumor evasion of immune surveillance, resulting in tumor progression. Also, it was found that “gene expression profile” of the microenvironmental cells, the phenotype of tumor-associated macrophages (TAM), the expression of matricellular proteins like SPARC and fibronectin, the overexpression of several types of matrix metalloproteinases (MMPs) like MMP-2 and MMP-9, or the tissue inhibitors of matrix metalloproteinases (TIMPs) may lead to a favorable or adverse outcome. With this review, we try to highlight the influence of microenvironment components over lymphoid clone progression and their prognostic impact in DLBCL patients.

Abstract
Non-Hodgkin lymphomas (NHL) are a heterogeneous group of lymphoproliferative malignancies with variable patterns of behavior and responses to therapy. NHL development and invasion depend on multiple interactions between tumor cells and non-neoplastic cells. Such interactions are usually modulated by several cytokines. Accordingly, it was demonstrated that matrix-metalloproteinase (MMP)-2 and MMP-9 were activated in human lymphoid cell lines by interleukin-6 (IL-6). The activation of these enzymes is associated with tumor invasion and metastasis in human cancers. MMPs are also activated in several cancers by osteopontin (OPN), a secreted glycoprotein that regulates cell adhesion, migration, and survival. However, it is still unclear if MMPs play a role in NHL development and if their activation is determined by OPN and/or IL-6. In the present study, two groups of 78 NHL patients and 95 healthy donors were recruited for the analysis of OPN, MMP-2, MMP-9 and IL-6.Significant higher circulating levels of MMP-2, MMP-9, OPN and IL-6 were observed in NHL patients when compared to healthy donors. Similar data were obtained by analyzing the activity of both MMP-2 and MMP-9. The multivariate regression model indicates that, in both NHL cases and healthy donors, OPN is associated with the increase of MMP-2 and MMP-9 levels independently of IL-6. These data were first confirmed by “in silico” analyses and then by “in vitro” experiments conducted on peripheral blood mononuclear cells randomly selected from both NHL patients and healthy donors.Overall, our data suggest that the activation of MMPs in NHL development is mostly associated with OPN. However, IL-6 may play an important role in the lymphomagenesis through the activation of other molecular pathways.

Semenza.

Abstract
Matrix metalloproteinase (MMP)-9 and neutrophil gelatinase-associated lipocalin (NGAL) have gained attention as cancer biomarkers. The inactive zymogen form of MMP-9 (pro-MMP-9) also exists as a disulphide-linked heterodimer bound to NGAL in humans. Leukaemias represent a heterogeneous group of neoplasms, which vary in their clinical behavior and pathophysiology. In this review, we summarize the current literature on the expression profiles of pro-MMP-9 and NGAL as prognostic factors in leukaemias. We also report the expression of the pro-MMP-9/NGAL complex in these diseases. We discuss the roles of (pro)-MMP-9 (active and latent forms) and NGAL in tumour development, and evaluate the mechanisms by which pro-MMP-9/NGAL may influence the actions of (pro)-MMP-9 and NGAL in cancer. Emerging knowledge about the coexpression and the biology of (pro)-MMP-9, NGAL and their complex in cancer including leukaemia may improve treatment outcomes.

Abstract
BACKGROUND Canine lymphoma represents the most frequent haematopoietic cancer and it shares some similarities with human non-Hodgkin lymphoma. Matrix metalloproteinases (MMPs) and vascular endothelial growth factor (VEGF) play a coordinated role during invasion and proliferation of malignant cells; however, little is known about their role in canine haematologic malignancies. The aim of this study was to investigate the mRNA and protein expression of VEGF and the most relevant MMPs in canine lymphoma. Lymph node aspirates from 26 B-cell and 21 T-cell lymphomas were collected. The protein expression levels of MMP-9, MMP-2 and VEGF-A were evaluated by immunocytochemistry, and the mRNA levels of MMP-2, MMP-9, MT1-MMP, TIMP-1, TIMP-2, RECK, VEGF-A and VEGF-164 were measured using quantitative RT-PCR. RESULTS MT1-MMP, TIMP-1 and RECK mRNA levels were significantly higher in T-cell lymphomas than in B-cell lymphomas. Higher mRNA and protein levels of MMP-9 and VEGF-A were observed in T-cell lymphomas than in B-cell lymphomas and healthy control lymph nodes. A positive correlation was found between MMP-9 and VEGF-A in T-cell lymphomas. Moreover, MMP-9, MT1-MMP, TIMP-1 and VEGF-A were expressed at the highest levels in high-grade T-cell lymphomas. CONCLUSIONS This study provides new information on the expression of different MMPs and VEGF in canine lymphoma, suggesting a possible correlation between different MMPs and VEGF, immunophenotype and prognosis.

Abstract
Single nucleotide polymorphisms in the promoter regions of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinase (TIMP) genes are associated with an adverse outcome in some cancers. We examined three polymorphisms: -1306C/T and -735C/T in MMP-2 and -418G/C in the TIMP-2 gene, using chain reaction restriction fragment length polymorphism typing analysis in 575 patients with non-Hodgkin's lymphoma (NHL). We examined the possible correlations between the three polymorphisms (MMP-2 (-1306C/T and -735C/T) and TIMP-2 gene (-418G/C)) and the clinical significance and survival rate in patients with NHL. The incidence of the CT, TT+CT genotypes and T allele of -735C/T was significantly higher in stage III and IV patients compared to stage I and II patients. In cases with bone marrow infiltration, the TT genotypes of the -1306C/T gene were significantly less frequent compared to CC genotypes. The CT, TT and CT+TT genotypes and T allele in patients exhibiting the -1306C/T polymorphism were significantly less frequent in patients with a large tumor size compared to a smaller tumor. The TT genotypes of the -735C/T polymorphism were more common in patients with a large tumor compared to those with a smaller tumor. The frequency of the -1306C/-735T haplotype in patients with a smaller tumor size was significantly higher compared to patients with a large tumor. The -1306T/-735C and -1306C/-735C haplotypes were significantly less frequent in patients with B-symptoms compared to those without. Interestingly, patients with the -735CT genotype exhibited a lower rate of survival. Our results demonstrate that certain MMP-2 and TIMP-2 gene polymorphisms potentially effect the progression or assessment of prognosis for NHL. This research warrants further, larger scale studies.

Abstract
Follicular lymphoma (FL) is the second-most common non-Hodgkin's lymphoma. The disease affects the lymph nodes, and 50% of patients present with bone marrow infiltration; however, the mechanisms involved in dissemination of the disease are not yet known. We previously reported that FL cells display an overexpression of Syk, a tyrosine kinase involved in many cellular processes including cell migration. Therefore, we sought to explore its role in the invasive process. Here, we show that FL patients display higher matrix metalloproteinase (MMP)-9 and vascular endothelial growth factor (VEGF) levels than healthy donors. Moreover, using Syk small interfering RNA and the Syk inhibitor R406, we demonstrate that, in FL cells, Syk is involved in the regulation of MMP-9 and VEGF expression, and that invasion and angiogenesis is mediated through a phosphatidylinositol-3 kinase (PI3K)-mammalian target of rapamycin module. Finally, using a FL xenograft mouse model we observe that fostamatinib (R788), inhibits MMP-9 expression and angiogenesis in vivo. Altogether, this study provides strong evidence that Syk represents an encouraging therapeutic target in FL and suggests the potential use of fostamatinib as an anti-invasive and anti-angiogenic drug.

Abstract
This study evaluates the mRNA expression profile of genes TIMP1, TIMP2, MMP2 and MMP9 in diagnostic bone marrow samples from 134 consecutive ALL children by real-time quantitative PCR. A significant association was observed between higher expression levels of MMP9 and low risk group and absence of extramedullary infiltration and higher expression levels of TIMP2 and MMP2 with T-ALL. TIMP1 gene expression values higher than the median were associated with a significantly lower 5-year event free-survival in univariable (P=0.04) and multivariable analysis (P=0.01). Our data address new information in the complex interaction of the migration/adhesion genes and childhood ALL.

Abstract
A morbillivirus infection of tumour cells is known to exert oncolytic activity, but the mechanism of this inhibitory action has not been well defined. Matrix metalloproteinases (MMPs) are important enzymes degrading the extracellular matrix and are often upregulated in malignant neoplasms. Recent studies have demonstrated that RECK may potently suppress MMP-2 and -9 activity, thus inhibiting angiogenesis and metastasis. In this study, real time quantitative polymerase chain reaction (RT-qPCR) was used to determine the effect of persistent infection with canine distemper virus (CDV) infection on the expression of MMPs and their inhibitors (TIMPS) in a canine macrophage/monocytic tumour cell line (DH82). The activity of proMMP-2 and proMMP-9 was also verified zymographically. Following CDV infection, MMP-2, TIMP-1 and TIMP-2 were down-regulated, while RECK was upregulated. These findings suggest that CDV infection restores RECK expression in tumour cells and may interfere with the intracellular processing of MMPs and TIMPs, thus possibly influencing tumour cell behaviour beneficially for the host. However, this needs to be verified in in vivo studies.

Abstract
The present study was carried out to clarify the role of matrix metalloproteinase-2 and -9 (MMP-2 and MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1), vascular endothelial growth factor (VEGF), and microvessel density (MVD) in the clinicopathologic behavior of childhood B-cell non-Hodgkin lymphoma (NHL). Paraffin-embedded biopsy specimens from 25 children with NHL were studied by immunohistochemically and the correlate the expression of these markers to clinicopathologic characteristics. Positive MMP-9 staining was associated with an increased prevalence of B-symptoms (p = .046). High microvessel density (MVD) showed a tendency toward an adverse outcome and it was correlated with clinical stage (p = .023). The event-free survival of high MVD patients was less than for those with low MVD, but the difference was not statistically significant (64.1% vs. 85.71% respectively, p = 0.15). The overall survival of high MVD patients was less than for those low with MVD and the difference was statistically significant (55.53% vs. 100% respectively, p = .039). Neither gelatinases nor VEGF correlated with age, sex, disease stage, the occurrence of bulky disease, or extranodal disease. The results showed that angiogenesis and angiogenic factors might have a role in development and clinical behavior of childhood NHL. Larger series of patients are needed to determine the prognostic value of angiogenesis in childhood non-Hodgkin lymphoma.

Abstract
The relationship between angiogenesis and eukaryotic translation initiation factor 4E (EIF4E) expression level in non-Hodgkin lymphoma (NHL) was studied. Mean microvessel density (MVD) and EIF4E were detected in 52 lymph node samples paraffin sections of patients with newly diagnosed NHL by the way of immunohistochemistry. Antisense EIF4E cDNA was cloned into plasmid pcDNA3. 1 (+) and transfected into Raji cells. A series of angiogenesis related factors, including vascular endothelial growth factor (VEGF), matrix metalloproteinases 9 (MMP-9) and tissue inhibitor of metalloproteinases-2 (TIMP-2) proteins were detected by Western blot. The results showed that: (1) The Expression of EIF4E and MVD was higher in aggressive lymphomas than in indolent lymphomas (P < 0.05)and the expression of EIF4E was positively correlated with MVD in lymph node of NHL (r = 0.695, P < 0.01). (2) Antisense EIF4E eukaryocytic expression vector (pcDNA3. 1-EIF4Eas) was constructed successfully. (3) EIF4E, VEGF and MMP-9 were expressed at high levels in Raji cells as compared to normal human peripheral blood monocular cells (NHPMC), and blockage of EIF4E expression brought down the expression of VEGF and MMP-9. However, TIMP-2 was undetectable in Raji cells, although a moderate level of TIMP-2 was detected in NHPMC. It was concluded that the increased EIF4E expression was associated with aggressive property of NHL.

Canine non-Hodgkin's lymphoma (NHL) is considered to be a good animal model for its human counterpart; nevertheless, comparative data on neo-angiogenesis are completely lacking. The aim of this study is to investigate the levels of serum vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) 2 and 9 in lymphoma-affected dogs. Circulating levels of VEGF and both MMP 2 and 9 activities significantly correlate with the WHO sub-stage b prognostic factor; moreover, VEGF at admission have an independent influence on the length of the disease free interval. As in humans, serum VEGF concentration and most likely also MMPs plasma activity have prognostic value in canine NHL spontaneous model.

Abstract
Extracellular proteases of the matrix metalloproteinase (MMP) and serine protease families participate in many aspects of tumour growth and metastasis. Using quantitative real-time RT–PCR analysis, we have undertaken a comprehensive survey of the expression of these enzymes and of their natural inhibitors in 44 cases of human prostate cancer and 23 benign prostate specimens. We found increased expression of MMP10, 15, 24, 25 and 26, urokinase plasminogen activator-receptor (uPAR) and plasminogen activator inhibitor-1 (PAI1), and the newly characterised serine proteases hepsin and matriptase-1 (MTSP1) in malignant tissue compared to benign prostate tissue. In contrast, there was significantly decreased expression of MMP2 and MMP23, maspin, and the protease inhibitors tissue inhibitor of metalloproteinase 3 (TIMP3), TIMP4 and RECK (reversion-inducing cysteine-rich protein with Kazal motifs) in the cancer specimens. The expression of MMP15 and MMP26 correlated positively with Gleason score, whereas TIMP3, TIMP4 and RECK expression correlated negatively with Gleason score. The cellular localisation of the expression of the deregulated genes was evaluated using primary malignant epithelial and stromal cell cultures derived from radical prostatectomy specimens. MMP10 and 25, hepsin, MTSP1 and maspin showed predominantly epithelial expression, whereas TIMP 3 and 4, RECK, MMP2 and 23, uPAR and PAI1 were produced primarily by stromal cells. These data provide the first comprehensive and quantitative analysis of the expression and localisation of MMPs and their inhibitors in human prostate cancer, leading to the identification of several genes involved in proteolysis as potential prognostic indicators, in particular hepsin, MTSP1, MMP26, PAI1, uPAR, MMP15, TIMP3, TIMP4, maspin and RECK.

Abstract
Expression and activity of matrix metalloproteinase-9 (MMP-9) as well as its relationship with hyaluronan (HA) and NF-kappaB activity were analyzed in two murine lymphoma cell lines with dissimilar migration and invasive behavior. MMP activity was evaluated by zymograms in supernatants, membrane extracts of tumor cells, and in the organs invaded by these cells. The more aggressive LBLa cell line showed MMP-9 activity in vitro, which increased after HA treatment and was blocked by anti-CD44 mAb. Such activity was not found in the less aggressive LBLc. MMP-9 and MMP-2 activity was found in organs invaded by both cell lines, although differential MMP-9 activity was observed in lung infiltrated only by LBLa cell line. NF-kappaB activation was evaluated to determine whether differential activity of MMP-9 was dependent on downstream signaling pathway, showing higher NF-kappaB activity in the more aggressive LBLa cell line. Our results showed that MMP-9 activity modulated by HA through NF-kappaB signaling pathway may be involved in the aggressive behavior of LBLa.

Abstract
Matrix metalloproteinase (MMP) 10 (stromelysin-2) is known to degrade various components of the extracellular matrix; however, the signals that regulate its expression and its role in lymphoma growth remain unknown. In the present work, we report the up-regulated expression of MMP10 in T lymphoma cells following contact with endothelial cells. The induction of MMP10 was found to be dependent on the specific interaction between LFA-1 and ICAM-1, which play a central role in regulating the expression of genes involved in the rate-limiting steps of lymphoma development. MMP10, but not MMP3 (stromelysin-1), was also up-regulated in human B lymphoma cells following exposure to IL-4, IL-6, and IL-13, but not to IL-1. To gain further insight into the role of MMP10 in lymphoma development, we generated lymphoma cell lines constitutively expressing high levels of MMP10 and studied these cells for their ability to form thymic lymphoma in vivo. Mice injected with lymphoma cells constitutively expressing MMP10 developed thymic lymphoma more rapidly than those injected with control lymphoma cells. These results provide the first in vivo evidence that overexpression of MMP10 promotes tumor development, and indicate that MMP10 induction is an important pathway activated not only upon ICAM-1/LFA-1-mediated intercellular contact, but also following activation of tumor cells with inflammatory cytokines.

Abstract
The tissue inhibitor of metalloproteinase-1 (TIMP1) is expressed in a subset of malignant lymphomas and can inhibit tumor spread and promote cell survival. Recent data suggest that TIMP1 expression may be regulated by signal transducer and activator of transcription (STAT)-3. Thus, we tested the hypothesis that TIMP1 expression is related to STAT3 activation in lymphomas, with a focus on anaplastic large cell lymphomas (ALCLs), which are known to express high levels of phosphorylated/active STAT3 (pSTAT3). Specific inhibition of STAT3 with a dominant-negative construct led to concentration-dependent down-regulation of TIMP1 expression in two anaplastic lymphoma kinase (ALK)(+) ALCL cell lines, Karpas 299 and SU-DHL-1. Using cDNA microarrays, ALK(+) ALCL cell lines consistently expressed the highest TIMP1 level among 29 lymphoma cell lines of various subtypes. The association between TIMP1 expression and high level of STAT3 activation was validated by Western blots and immunostaining using antibodies specific for pSTAT3 and TIMP1. We further evaluated the relationship between TIMP1 expression and STAT3 activation in 43 ALCL tumors (19 ALK(+) and 24 ALK(-)) using immunohistochemistry and a tissue microarray. The TIMP1(+) group had a mean of 64% pSTAT3(+) cells as compared to 23% pSTAT3(+) cells in the TIMP1(-) group (P = 0.002). As expected, TIMP1 positivity was higher in the ALK(+) group (15 of 19, 79%) compared with the ALK(-) group (5 of 24, 21%; P = 0.0002) because NPM-ALK restricted to ALK(+) tumors was previously shown to activate STAT3. In conclusion, STAT3 directly contributes to the high level of TIMP1 expression in ALK(+) ALCL, and TIMP1 expression correlates with high level of STAT3 activation in ALCL. TIMP1, as a downstream target of STAT3, may mediate the anti-apoptotic effects of STAT3.

Abstract
Systemic and local cytokine environment may modulate the immunogenicity of colorectal cancer cells, and affect anti-tumor immune functions of tumor-infiltrating lymphocytes. We therefore investigated cytokine mRNA expression patterns in tumors and peripheral blood mononuclear cells (PBMC) from patients with colorectal adenocarcinoma. IL-2, IFN-gamma, tumor necrosis factor-alpha (TNF-alpha), IL-4, IL-6, IL-8, IL-10 and IL-1 beta mRNAs in single cell suspension of freshly isolated colorectal cancer tissue were studied by RT-PCR. Frequencies of cytokine gene expression were compared to those in normal colonic mucosa from tumor patients. The frequencies of IL-2, IFN-gamma, IL-4 and IL-10 gene expression were also determined in peripheral blood mononuclear cells from patients with colorectal adenocarcinoma and compared to those of healthy individuals. Tumor samples were more frequently positive for IFN-gamma, IL-2, TNF-alpha and IL-10 gene expression than normal mucosa (p=0.0001, p=0.0118, p=0.001 and p<0.0001, respectively). Frequencies of IL-2 and TNF-alpha gene expressions were significantly higher in tumors with a diameter <5 cm, than in those with a diameter >5 cm. The genes for IL-6, IL-1 beta and IL-8 were commonly expressed in both tumor tissue and normal colonic mucosa. IFN-gamma transcripts were detected in more PBMC samples from patients with colorectal cancer than those from normal controls (p=0.0449). Thus, colorectal cancer tissue is characterized by a specific pattern of cytokine gene expression. It is likely that multiple interactions between pro- and anti-inflammatory cytokines regulate tumor growth and the functional activity of tumor-infiltrating lymphocytes.

Abstract
Matrix metalloproteinases (MMPs) are responsible for the degradation of extracellular matrix and have an important role in tumour metastases. We investigated the role of MMP-2 and MMP-9 in Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). The serum samples of patients with HD (n = 12), NHL (n = 30) and healthy control (n = 22) were analysed for MMP-2 and MMP-9. An immunoassay method was used for the determination of MMP-2 and MMP-9 levels. No statistical significance was found between HD and NHL groups for levels of MMP-2. There were no relation between MMP-2, MMP-9 levels and clinical characteristics of patients. The mean MMP-9 levels were found to be 555.6 +/- 140 ng/ml, 446.6 +/- 53.6 ng/ml and 111.2 +/- 10.3 ng/ml in HD, NHL and control groups, respectively. Our results suggest that MMP-9 levels are substantially increased in HD and NHL when compared with controls and may probably be used for distinguishing the benign diseases from malign lymphomas.

Abstract
Astrocytes are intimately involved in the mechanisms of neural injury and repair. They participate in a variety of homeostatic functions and elicit repair responses as balance mechanisms. Currently, there is a growing appreciation of a more active role of astrocytes in neuronal signaling and function. One key homeostatic mechanism of astrocytes in tissue repair is maintained through their production of tissue inhibitors of metalloproteinases (TIMPs). The family of TIMPs (1-4) plays a central regulatory role as inhibitors of matrix metalloproteinases (MMPs), enzymes involved in extracellular matrix maintenance and remodeling. Recently, TIMP-1, the inducible form, has been identified as a multifunctional molecule with divergent functions. It participates in wound healing and regeneration, cell morphology and survival, tumor metastasis, angiogenesis, and inflammatory responses. An imbalance of MMP/TIMP regulation has been implicated in several inflammatory diseases of the central nervous system (CNS). Here we review the conundrums of TIMP-1 regulation in CNS pathophysiology. We propose that astrocyte-TIMP-1 may play an important role in CNS homeostasis and disease. Astrocyte TIMP-1 expression is differentially regulated in inflammatory neurodegenerative diseases and may have significant therapeutic relevance.

Abstract
Matrix metalloproteinase-9 (MMP-9), a matrix-degrading enzyme, is crucial in tumor invasion and metastasis and is implicated in leukocyte extravasation. In this report, we demonstrate that during growth of the D1-7,12-dimethylbenzanthracene-3 mammary tumor in BALB/c mice, there is progressive up-regulation of MMP-9 in splenic T cells at both the transcriptional and translational levels. Our previous work has identified several factors produced by this tumor, including PGE(2), GM-CSF, and phosphatidyl serine; however, none of these agents induces increased production of MMP-9 by normal splenic T cells. Although not produced by the tumor, TNF-alpha and IL-6 are up-regulated in both macrophages and B cells in tumor-bearing mice. Exposure of normal T cells to these two cytokines, however, also fails to up-regulate MMP-9 production. Vascular endothelial growth factor (VEGF) is produced by many tumors, and we determined that the mammary tumor used in our studies expresses high levels of this angiogenic growth factor. Importantly, splenic T cells from tumor bearers constitutively produce increased amounts of VEGF, and treatment of normal T cells with VEGF results in up-regulated MMP-9 production. Of crucial importance is the finding that tumor-infiltrating T cells also produce high levels of VEGF and MMP-9. Our studies indicate that VEGF can act directly on T lymphocytes and that elevated VEGF levels may contribute to the aberrant MMP-9 secretion by mammary tumor bearers' T cells.

Abstract
Enhanced expression of (pro)matrix metalloproteinase-9 (MMP-9) is associated with human tumor invasion and/or metastasis. COH cells derived from a highly invasive and metastatic Ewing's sarcoma constitutively express proMMP-9. Transfection of a double stranded RNA that targets the MMP-9 mRNA into COH cells depleted the corresponding mRNA and protein as demonstrated by reverse transcriptase-PCR, enzyme-linked immunosorbent assay, and gelatin zymography. proMMP-9 extinction resulted in the following: (i) decreased spreading on extracellular matrix (fibronectin, laminin, collagen IV)-coated surfaces, (ii) inhibition of migration toward fibronectin, and (iii) induced aggregation, which was specifically disrupted by a function-blocking E-cadherin antibody. MMP-9 knockdown concomitantly resulted in increased levels of surface E-cadherin, redistribution at the plasma membrane of beta-catenin, and its physical association with E-cadherin. Moreover, induction of E-cadherin-mediated adhesion was associated with RhoA activation and changes in paxillin cytoskeleton. Finally, an inhibitor of gelatinolytic activity of pro-MMP9 did not reduce COH cell migration confirming that the enzymatic property of COH MMP-9 was not required for migration toward fibronectin. Overall, our observations define a novel critical role for proMMP-9 in providing a cellular switch between stationary and migratory cell phases.

Abstract
Although tumors frequently show elevated protease activities, the concept of anti-proteolytic cancer therapy has lost momentum after failure of clinical trials with broad-spectrum matrix metalloproteinase inhibitors. Thus we need to adapt our design strategies for protease inhibitors. Here, we employed a series of seven structurally fine-modulated and pharmacokinetically closely related synthetic 4-amidinobenzylamine-based inhibitors with distinct selectivity for prototypical serine proteases in a murine T cell lymphoma liver metastasis model. This in vivo screening revealed efficacy of urokinase inhibitors but no correlation between urokinase selectivity or affinity and anti-metastatic effect. In contrast, factor Xa-selective inhibitors were more potent, demonstrating factor Xa or a factor Xa-like serine protease likely to be more determinant in this model. Factor Xa selectivity, but not affinity, significantly improved anti-metastatic efficacy. For example, factor Xa inhibitors CJ-504 and CJ-510 exert similar affinity for factor Xa (K(i)=14 nM versus 8.8 nM) but CJ-504 was 70-fold more selective for factor Xa. This correlated with higher anti-metastatic efficacy (58.8% with CJ-504; 28.2% with CJ-510). Our results show that among the protease inhibitors employed that have affinities in the nanomolar range, the strategy of selectivity-optimization is superior to further improvement of affinity to significantly enhance anti-metastatic efficacy. This appreciation may be important for the future rational design of new anti-proteolytic agents for cancer therapy.

Abstract
Enhanced expression of matrix metalloproteinase-9 (MMP-9) correlates with invasion during tumor progression. Interferons (IFNs) inhibit MMP-9 activation in response to tumor necrosis factor-alpha (TNF-alpha), and the latter activates the MMP-9 gene through NF-kappaB. Understanding the molecular basis for MMP-9 inhibition may provide tools to control cell invasion. The data reported here show the critical role of interferon regulatory factor-1 (IRF1) in the inhibition of MMP-9. (i) IFN treatment suppresses TNF-alpha-induced MMP-9 reporter activity in STAT1(+/+) cells but not in STAT1(-/-) cells. (ii) IRF1 transfection blocks TNF-alpha-mediated MMP-9 activation. (iii) IFNs phosphorylate STAT1 and induce IRF1 but do not affect Ikappa-B degradation nor NF-kappaB nuclear translocation. (iv) Nuclear NF-kappaB (p50/p65) and IRF1, but not STAT1, bind to the MMP-9 promoter region containing an IFN-responsive-like element overlapping the NF-kappaB-binding site. (v) Recombinant IRF1, although unable to bind to an NF-kappaB consensus sequence, competes with NF-kappaB proteins for binding to the MMP-9 promoter. (vi) Conversely recombinant p50/p65 proteins reduce IRF1-DNA binding. (vii) In cells cotransfected with IRF1 and/or p65 expression vectors, an excess of IRF1 reduces MMP-9 reporter activity, whereas an excess of p65 blocks the inhibitory effect of IFN-gamma. Thus, in contrast to the known synergism between IRF1 and NF-kappaB, our data identify a novel role for IRF1 as a competitive inhibitor of NF-kappaB binding to the particular MMP-9 promoter context.

Abstract
Platelet Activating Factor (PAF), an inflammatory bioactive lipid, has been shown to be involved in the regulation of the activity of matrix metalloproteinases (MMPs). In view of the role played by MMPs in tumor cell invasiveness, we investigated whether PAF influences MMP activity in a system of neuroblastoma clones, the AA5 and AE12 cells, isolated from the human LaN1 neuroblastoma cell line. These clones were characterized by an inverse relationship between invasiveness and differentiative capacity and by the expression of specific cell surface PAF receptors. We found that the levels of mRNAs specific for MMP-2 and for MT1-MMP, the MMP-2 activator, were reduced in both clones treated with 300 nM PAF. These changes are consistent with the reduced secretion and activation of MMP-2 found in the neuroblastoma clones exposed to PAF. These effects were accompanied by an inhibition of invasiveness through Matrigel and by a promotion of differentiation, as revealed by an increased percentage of cells with neurites. The finding that both neuroblastoma clones exposed to the metalloproteinase inhibitors, BB3103 and 1,10-phenanthroline, increased their differentiative capacity and reduced their invasiveness through Matrigel, represents a further indication that PAF modulates differentiation and invasiveness by affecting the activity of MMPs.
