Abstract
Peptide drug conjugates offer a novel strategy to achieve controlled drug release. This approach avoids the clinical obstacles of non-specific toxicity and overall drug resistance of conventional cytotoxic agents, such as paclitaxel. MMP2 plays important functions in tumour proliferation and metastasis. Herein, we conjugated the paclitaxel with a hexapeptide which is specific recognized by MMP2 protein. The conjugate is dissociated upon the MMP2 specific proteolysis at COOH terminal of hexapeptide, PVGLIG.The results clearly indicated that the PVGLIG-paclitaxel conjugate significantly enhanced the tumor specificity against HT-1080 and U87-MG tumour cells. Our finding suggested that the hexapeptide PVGLIG is capable to act as a controlled and sustained drug carrier of paclitaxel for the treatment against tumour proliferation and metastasis with high MMP2 expression.

Abstract
Flavonoid glycosides, isorhamnetin 3-capital O, Cyrillic-beta-d-glucoside, and quercetin 3-O-beta-d-glucoside were isolated from Salicornia herbacea and their inhibitory effects on matrix metalloproteinase-9 and -2 (MMP-9 and -2) were evaluated in human fibrosarcoma cell line (HT1080). In zymography experiments, these flavonoid glycosides led to the reduction of the expression levels and activities of MMP-9 and -2 without any significant difference between these flavonoid glycosides. Protein expression levels of both MMP-9 and MMP-2 were inhibited and TIMP-1 (tissue inhibitor of metalloproteinase-1) protein level was enhanced by these flavonoid glycosides. Moreover, a transfection study carried out with AP-1 reporter construct revealed that the reporter activity was suppressed by treatment with isorhamnetin 3-capital O, Cyrillic-beta-d-glucoside. Therefore, these results suggested that these flavonoid glycosides have a potential as valuable natural chemopreventive agents for cancer.

Abstract
The use of adenovirus serotype 2 or 5 (Ad2/5) E1A as therapy for human malignancy requires an understanding of the mechanisms involved in E1A-induced tumor suppression. The prevailing use of E1A in the treatment of human malignancy stresses the non-immunologically mediated, anti-tumorigenic activities of E1A. However, the capacity of E1A to elicit a NK-cell and T-cell anti-tumor immune response and to sensitize tumor cells to lysis by immune effector molecules utilized by NK cells and T cells is also an important component of the anti-tumorigenic activity of E1A. This immune-mediated anti-tumorigenic activity of E1A is not shared by functionally similar viral oncoproteins such as the human papillomavirus type 16 (HPV16) E7 oncoprotein and is dependent on the capacity of E1A to interact with transcriptional coadapter, p300. To further define the molecular mechanisms whereby E1A reduces tumorigenicity, we compared total cellular gene expression in H4 cells, a human fibrosarcoma cell line, to gene expression in H4 cells stably expressing E1A, E7, or mutant forms of E1A that do not bind p300. The expression of E1A, but not E7, in H4 cells modulated the expression of cellular genes that may promote apoptosis, enhance immunogenicity and reduce tumor cell metastasis. The difference in the ability of E1A and E7 to modulate the expression of cellular genes that may influence tumorigenicity was largely attributable to distinct interactions of E1A and E7 with p300. Results of this study will be useful in designing novel strategies to augment the anti-tumorigenic activities of E1A.

Abstract
Overexpression of the transcription factor Snail in epithelial MDCK cells promotes the epithelial-mesenchymal transition (EMT) and the acquisition of an invasive phenotype. We report here that the expression of Snail is associated with an increase in the promoter activity and expression of the matrix metalloproteinase MMP-9. The effect of Snail silencing on MMP-9 expression corroborates this finding. Induced transcription of MMP-9 by Snail is driven by a mechanism dependent on the MAPK and phosphoinositide 3-kinase (PI3K) signalling pathways. Although other regions of the promoter were required for a complete stimulation by Snail, a minimal fragment (nucleotides -97 to +114) produces a response following an increased phosphorylation of Sp-1 and either Sp-1 or Ets-1 binding to the GC-box elements contained in this region. The expression of a dominant negative form of MEK decreased these complexes. A moderate increase in the binding of the nuclear factor kappaB (NFkappaB) to the upstream region (nucleotide -562) of the MMP-9 promoter was also observed in Snail-expressing cells. Interestingly, oncogenic H-Ras (RasV12) synergistically co-operates with Snail in the induction of MMP-9 transcription and expression. Altogether, these results indicate that MMP-9 transcription is activated in response to Snail expression and that it might explain, at least in part, the invasive properties of the Snail-expressing cells.

Abstract
Members of the matrix metalloproteinase (MMP) family of enzymes participate in matrix remodeling and share a number of structural and functional features. The activity of this family of proteinases is carefully regulated at the level of zymogen activation and by a family of specific inhibitors termed tissue inhibitors of metalloproteinases (TIMP). It is now becoming clear that levels of certain MMPs are modulated by their association with cellular receptors that mediate their rapid internalization and degradation. In the current investigation we report that the amount of MMP-9 in conditioned cell culture medium is significantly increased when mouse embryonic fibroblasts are grown in the presence of the 39-kDa receptor-associated protein (RAP), an antagonist of ligand binding to low density lipoprotein receptor-related protein (LRP). In vitro assays reveal that the MMP-9.TIMP-1 complex binds to LRP with high affinity and that the binding determinant for LRP appears to reside on MMP-9. Cell lines expressing LRP mediate the internalization of 125I-labeled MMP-9.TIMP-1 complexes, whereas cell lines genetically deficient in LRP show a diminished capacity to mediate the cellular catabolism of MMP-9.TIMP-1 complexes. The results demonstrate that LRP is a functional receptor for MMP-9 and suggest a major role for LRP in modulating remodeling of the extracellular matrix by regulating extracellular proteinase activity.

Abstract
BACKGROUND Over 80% of patients with osteosarcoma treated with excision alone develop pulmonary metastases, suggesting that the majority of patients with this disease harbor "micrometastases" at diagnosis. There are no histologic or molecular variables which can predict the presence or absence of micrometastasis. Matrix metalloproteinases (MMPs) are a class of matrix- and basement membrane-degrading enzymes whose expression is associated with tumor cell invasive and metastatic behavior. One of these enzymes, MMP-9 or gelatinase B, is expressed in developing and remodeling bone and in osteosarcoma cell lines. We speculated that MMP-9 expression might be associated with the micrometastatic behavior of osteosarcoma. PROCEDURE We examined a series of pediatric primary osseous osteosarcomas and metastases for the expression of MMP-9, using a monoclonal antibody. RESULTS We found intense MMP-9 immunostaining in most tumor cells in all samples of pretreatment osteosarcomas. In all postchemotherapy resection samples, tumor cells stained similarly, but there were fewer positively staining cells overall. In 4 of 5 metastastic lesions examined, intense immunostaining for MMP-9 was detected. CONCLUSIONS These results suggest that MMP-9 expression is common in osteosarcoma, and that further study of the role of MMP-9 in pediatric osteosarcoma behavior is warranted.

Abstract
Recent data suggest that patients with more hypoxic solid tumors are more likely to develop metastases and die. We speculated that upregulation of the metastasis-associated type IV collagenase MMP-9 (gelatinase B) by hypoxia might be correlated with the increased risk of distant failure in patients with hypoxic tumors. The promoter for MMP-9 contains consensus binding sites for the transcription factors NFkappaB and AP-1 which are upregulated under hypoxic conditions in HeLa cells and these transcription factors are critical to transcriptional activation of the MMP-9 gene. A variety of tumor cell lines were examined for induction of MMP-9 and the related protease MMP-2 under hypoxic conditions. Although hypoxia did upregulate MMP-9 in one alveolar rhabdomyosarcoma cell line, we were unable to demonstrate a consistent hypoxia-mediated increase in MMP-9 protein, RNA, or transcriptional activity measured with reporter constructs. These results suggest that MMP-9 expression is not directly affected by exposure to hypoxia in vitro.

Abstract
Tumor-stromal interactions appear to play an important role in the induction of metalloproteinase expression in malignant tumors. We describe a tissue culture system in which expression of MMP-9 (gelatinase B or the 92 kDa type IV collagenase/gelatinase) was induced by co-cultivation of fibroblasts with breast cancer cell lines. While neither the breast cancer cells nor the normal rat embryo fibroblasts made MMP-9 alone in culture, human MMP-9 was made in the co-cultures. The MMP-9 was secreted in a latent form. The induction occurred at least in part through increases in the MMP-9 mRNA levels in the breast cancer cells. These increases did not appear to require protein synthesis. Conditioned medium from the fibroblasts could duplicate the induction of MMP-9 in the breast cancer cell lines. The active factor in the medium was inactivated by heat or by trypsin suggesting that it was a protein. This protein was in the size range of 30-100 kDa. Thus, fibroblasts could secrete a factor which was able to regulate the expression of MMP-9 in breast cancer cells.

Abstract
During progression towards malignancy, many tumor cells display changes in their repertoire of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs). The recent finding that many members of the MMPs are regulated by protooncogenes may explain the frequent observation of changes in MMP gene expression during progression of many tumor types. While studies involving enzymatic assays of MMPs are usually confined to one or a few MMPs, reverse transcription-PCR (RT-PCR) permitted the analysis of seven members of the MMP family and two members of the TIMP family in several normal and transformed cell lines. RT-PCR permitted us to confirm the observation that MMP-9 is activated following transformation and also to observe the previously unreported activation of MMP-7 in SV40-transformed cells. It has previously been found that MMP-1, -2, -3, -8, and -9 are upregulated by phorbol esters; we have found that MMP-10 is also upregulated by phorbol esters. The phorbol ester upregulation of MMP-1, -3, and -10 was found to be abolished in cells transformed by SV40 virus. Several studies have shown that MMP-1 is upregulated by an integrin-mediated signal transduction pathway. This study demonstrates that MMP-3 and MMP-10 are also regulated by integrin-mediated signal transduction and that upregulation by this pathway is abolished following SV40 transformation. In summary, the more global view of MMP expression afforded by RT-PCR indicates that MMP-1, -3, and -10 are regulated by both integrin-mediated signal transduction and phorbol esters. While fibroblasts and transformed bone cells express several members of the MMP gene family, several other cell types do not express MMPs.

Abstract
The invasive character of squamous cell carcinoma of the head and neck represents a major challenge to the clinician since most often these tumors require extensive surgical resection impairing important physiological functions including speech and swallowing. Additionally, in many cases costly reconstructive surgery is required to repair the adverse cosmetic effects of the resective surgery. Thus, there is an urgent need to understand the molecular mechanism(s) which underlie the local and regional spread of this disease. Since the ability of tumor cells to invade into surrounding structures requires hydrolytic action much effort has been spent on identifying the hydrolases involved in this process. Some of the enzymes which have been implicated in the spread of head and neck cancer include the urokinase-type plasminogen activator and several members of the collagenase family such as type I and IV collagenases and the stromelysins synthesized either by the tumor cells or in the surrounding fibroblasts. More recent studies have addressed the mechanism(s) by which these hydrolases are overexpressed in invasive cancer. In the tumor cells themselves, work has focused on defining the transcriptional requirements for enzyme synthesis and addressing how the appropriate transcription factors are activated by signal transduction pathways. In contrast, where the hydrolases (e.g. stromelysin-2 and stromelysin-3) are produced by the fibroblasts, current investigations are directed at identifying tumor-derived growth factors which lead to the inducible expression of the enzymes in the stromal cells. The ultimate goal of these studies is to develop novel therapeutic interventions which decrease the invasive capacity of head and neck cancer leading to longer survival times and enhanced quality of life for patients afflicted with this disease.
