Abstract
Colorectal cancer (CRC) is one of the most frequently occurring malignancy tumors with a high morbidity additionally, CRC patients may develop liver metastasis, which is the major cause of death. Despite significant advances in diagnostic and therapeutic techniques, the survival rate of colorectal liver metastasis (CRLM) patients remains very low. CRLM, as a complex cascade reaction process involving multiple factors and procedures, has complex and diverse molecular mechanisms. In this review, we summarize the mechanisms/pathophysiology, diagnosis, treatment of CRLM. We also focus on an overview of the recent advances in understanding the molecular basis of CRLM with a special emphasis on tumor microenvironment and promise of newer targeted therapies for CRLM, further improving the prognosis of CRLM patients.

Abstract
AIM To evaluate the dentinogenetic effects of tissue inhibitor of metalloprotease (TIMP1) on human pulp cells in vitro and rat pulp tissue in vivo. METHODOLOGY The effect of TIMP1 on pulp cell functions related to hard tissue formation as part of the wound healing process (i.e. biocompatibility, proliferation, differentiation and mineralized nodule formation) was evaluated in vitro and using a direct pulp capping experimental animal model in vivo. The effects of different-sized cavity preparations on hard tissue formation induced by ProRoot MTA at 2 weeks were evaluated using micro-computed tomography (micro-CT). Tertiary dentine formation quality and quantity after pulp capping using TIMP1, ProRoot MTA and phosphate-buffered saline (PBS) was also evaluated after 4 weeks using micro-CT in term of dentine volume (DV), dentine mineral density (DVD) and histological analysis. The data were evaluated by Student's t-test, one-way ANOVA with Tukey's post hoc test, the Kruskal-Wallis test or the Steel-Dwass test. P values < 0.05 were considered statistically significant. RESULTS TIMP1 significantly stimulated dental pulp stem cell proliferation, differentiation, and mineralization and was more biocompatible compared with the PBS control (P < 0.05). In the pulp capping model, the amount of tertiary dentine that formed was directly proportional to the size of the pulp exposure; greater amounts of tertiary dentine were observed in pulps with larger exposures after 2 weeks. 4-week samples of TIMP1 and ProRoot MTA had similar characteristics, but both sample significantly induced tertiary dentine formation beneath the cavity compared with PBS (P < 0.05) under standardized cavity preparations. CONCLUSIONS TIMP1 has an important role in pulpal wound healing, which makes it a potential biological pulp capping material and candidate molecule for regenerative endodontic therapy.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) remains one of the most aggressive malignancies to date, largely because it is associated with high metastatic risk. Pancreatic tumors have a characteristic tendency to metastasize preferentially to the liver. Over the past two decades, it has become evident that the otherwise hostile milieu of the liver is selectively preconditioned at an early stage to render it more conducive to the engraftment and growth of disseminated cancer cells, a concept defined as pre-metastatic niche (PMN) formation. Pancreatic cancer cells exploit components of the tumor microenvironment to facilitate their migration out of the primary tumor, which often involves conversion of pancreatic cancer cells from an epithelial to a mesenchymal phenotype via the epithelial-to-mesenchymal transition. Pancreatic stellate cells and matrix stiffness have been put forward as major drivers of invasiveness in PDAC. Even before the onset of pancreatic cancer cell dissemination, soluble factors and extracellular vesicles secreted by the primary tumor, and possibly even premalignant lesions, help shape a supportive niche in the liver by providing vascular docking sites for circulating tumor cells, enhancing vascular permeability, remodeling the extracellular matrix and recruiting immunosuppressive inflammatory cells. Emerging evidence suggests that some of these tumor-derived factors may represent powerful diagnostic or prognostic biomarkers. Though our understanding of the mechanisms driving PMN formation in PDAC has expanded considerably, many outstanding questions and challenges remain. Further studies dissecting the molecular and cellular events involved in hepatic PMN formation in PDAC will likely improve diagnosis and open new avenues from a therapeutic standpoint.

Abstract
Poly (ADP-ribose) polymerase 1 (PARP-1) is a crucial contributor to exacerbate ischemia and reperfusion (IR) injury and cancer process. However, there is little research into whether PARP-1 affects the hepatocellular carcinoma (HCC) recurrence after liver transplantation. In this study, we investigated the influence of PARP-1 on hepatic neutrophil mobilizing and phenotype shifting which may lead to HCC recurrence after liver transplantation. We found that rats received the grafts with warm ischemic injury had higher risk of HCC recurrence, which was markedly prevented by pharmacological inhibition of PARP-1 after liver transplantation. In mouse models, the up-regulation of PARP-1 was closely related to the greater tumor burden and increased hepatic susceptibility to recurrence after IR injury. The reason was that high hepatic PARP-1 led to increased liver CXCL1 levels, which in turn promoted recruitment of neutrophils. Both blocking CXCL1/CXCR2 signaling pathway and depleting neutrophils decreased tumor burden. Moreover, these infiltrating neutrophils were programmed to a proangiogenic phenotype under the influence of PARP-1 in vivo after hepatic IR injury. In conclusion, IR-induced PARP-1 up-regulation increased the hepatic recruitment of neutrophils through regulation of CXCL1/CXCR2 signaling and polarized hepatic neutrophils to proangiogenic phenotype, which further promoted HCC recurrence after transplantation.

Abstract
Tumor invasion and metastasis is a highly complicated, multi-step phenomenon. In the complex event of tumor progression, tumor cells interact with basement membrane and extracellular matrix components. Proteolytic enzymes (proteinases) are involved in the degradation of extracellular matrix, but also in cancer invasion and metastasis. The four categories of proteinases (cysteine-, serine-, aspartic-, and metalloproteinases) are named and classified according to the essential catalytic component in their active site. We and others have shown that proteolytic enzymes play a major role not only in colorectal cancer (CRC) invasion and metastasis, but also in malignant transformation of precancerous lesions into cancer. Tissue and serum-plasma antigen concentrations of proteinases might be of great value in identifying patients with poor prognosis in CRC. Our results, in concordance with others indicate the potential tumor marker impact of proteinases for the early diagnosis of CRC. In addition, proteinases may also serve as potential target molecules for therapeutic agents.

Abstract
Cancer is the final result of uninhibited cell growth that involves an enormous group of associated diseases. One major aspect of cancer is when cells attack adjacent components of the body and spread to other organs, named metastasis, which is the major cause of cancer-related mortality. In developing this process, metastatic cells must successfully negotiate a series of complex steps, including dissociation, invasion, intravasation, extravasation, and dormancy regulated by various signaling pathways. In this review, we will focus on the recent studies and collect a comprehensive encyclopedia in molecular basis of metastasis, and then we will discuss some new potential therapeutics which target the metastasis pathways. Understanding the new aspects on molecular mechanisms and signaling pathways controlling tumor cell metastasis is critical for the development of therapeutic strategies for cancer patients that would be valuable for researchers in both fields of molecular and clinical oncology.

Abstract
Zoledronic acid (ZOL), a nitrogen-containing compound, is effective in the treatment of skeletal disorders, but its long-term use in high doses gives rise to complications such as osteonecrosis. We aimed to investigate the effect of low-dose ZOL on the expression of the neural cell adhesion molecule (NCAM), which may be correlated with tumor growth and spinal cord metastasis in lung adenocarcinoma with neuroendocrine differentiation. First, we used the small hairpin RNA technique to directly knock down NCAM expression in cells of a murine lung adenocarcinoma line, line 1 cells, and found that the tumor cells generated showed lower invasive capacity, slower tumor growth, and lesser tendency for spinal cord metastasis than control cells. Further, ZOL decreased NCAM expression and invasiveness in line 1 tumor cells in vitro. Line 1/lacZ cells, a stable clone tagged with the lacZ gene, were introduced into mice, followed by ZOL treatment (1 μg/kg/weekly). Low-dose ZOL significantly reduced spinal cord metastasis probably through reduced NCAM expression in vivo. These findings indicated that NCAM is involved in tumor growth and spinal cord metastasis of lung adenocarcinoma with neuroendocrine differentiation. Treatment with low-dose ZOL can reduce NCAM expression that may contribute toward reduced spinal cord metastasis, suggesting that NCAM is an alternative therapeutic target and that the low-dose ZOL treatment protocol is a reasonable approach for its treatment.

Abstract
Matrix metalloproteinases (MMPs) play an important role in the degradation of extracellular matrix components crucial for tumor growth, invasion and metastasis. MMPs are controlled by natural inhibitors called tissue inhibitors of metalloproteinases (TIMPs). We and others have demonstrated that MMPs and TIMPs are especially important in the process of tumor invasion, progression and the metastasis of colorectal cancer (CRC). It has been proposed that MMPs and TIMPs might play a part not only in tumor invasion and initiation of metastasis but also in carcinogenesis from colorectal adenomas. Several recent studies demonstrated that high preoperative serum or plasma MMP-2, MMP-9 and TIMP-1 antigen levels are strong predictive factors for poor prognosis in patients with CRC and their determination might be useful for identification of patients with higher risk for cancer recurrence. MMP-9 and TIMP-1 have significant potential tumor marker impact in CRC. Their diagnostic sensitivity is consistently higher than those of conventional biomarkers. The pharmacological targeting of CRC by the development of a new generation of selective inhibitors of MMPs, that is highly specific for certain MMPs, is a promising and challenging area for the future.

Abstract
To identify invasion-associated genes in extranodal natural killer (NK)/T-cell lymphoma, we performed microarray analysis on seven tumor samples and two control pools (composed of normal NK cells and T cells, tonsil and spleen) using Affymetrix GeneChip. Compared with all control pools, 59 uniquely expressed genes were discovered in the tumor samples. Overexpressed genes related to proteolysis, cell motility and chemotaxis, including CTSL, uPAR, TIMP-1, CXCL9, CXCL11 and DEFB1, were identified. Comparing the gene expression profiles of five upper aerodigestive tract (UAT) cases with two non-UAT cases, we found some overexpressed genes in non-UAT cases related to proteolysis and cell adhesion function, including matrix metalloproteinase 9 (MMP-9). Immunohistochemistry detection was performed on 34 paraffin sections to evaluate the expression of selected genes. A correlation of urokinase-type plasminogen activator receptor (uPAR) expression with MMP-9 expression was revealed. Analysis of prognosis demonstrated that expressions of MMP-2 and MMP-9 were closely correlated with a poor prognosis. These invasion-associated genes may become targets for diagnostic and therapeutic procedures.

Abstract
Chronic inflammation is an important risk factor for the development of cancers. The link between chronic inflammation and the risk of developing cancer is now well established. At least 20% of all cancers arise in association with infection and chronic inflammation. Inflammation and cancer are linked both along intrinsic (driven by genetic events causing malignancy) and extrinsic (driven by inflammatory conditions predisposing to tumor) pathways. Proteinases are key contributors to the breakdown and reconstitution of extracellular matrix components in physiological processes and pathological conditions, including destructive diseases and tumor progression. Matrix metalloproteinases are especially essential in the complex process of coregulation between cellular components of the tumor environment, and they are considered as potential diagnostic and prognostic biomarkers in many types and stages of cancer. Although the link between chronic inflammation, proteinases and risk of developing cancer is now well established, several open questions remain. The most exciting challenge is to find the best approach to target cancer-associated inflammation in patients with cancer. With respect to matrix metalloproteinases, the development of a new generation of selective inhibitors is a promising area of research.

Abstract
Proteases are crucial for development, tissue remodeling, and tumorigenesis. Matrix metalloproteinases (MMPs) family, in particular, consists of more than 20 members with unique substrates and diverse function. The expression and activity of MMPs in a variety of human cancers have been intensively studied. MMPs have well-recognized roles in the late stage of tumor progression, invasion, and metastasis. However, increasing evidence demonstrates that MMPs are involved earlier in tumorigenesis, e.g., in malignant transformation, angiogenesis, and tumor growth both at the primary and metastatic sites. Recent studies also suggest that MMPs play complex roles in tumor progression. While most MMPs promote tumor progression, some of them may protect the host against tumorigenesis in a context-dependent manner. MMPs have been chosen as promising targets for cancer therapy on the basis of their aberrant up-regulation in malignant tumors and their ability to promote cancer metastasis. Although preclinical studies testing the efficacy of MMP suppression in tumor models were so encouraging, the results of clinical trials in cancer patients have been rather disappointing. Here, we review the complex roles of MMPs and their endogenous inhibitors such as tissue inhibitors of metalloproteinase in tumorigenesis and strategies in suppressing MMPs.

Abstract
Inconsistencies plague our understanding of the role of neutrophils in cancer and the literature provides evidence for a duality in neutrophil activity on the outcome of cancer. Here, the different effects of neutrophils during the multiple subprocesses of cancer development and progression are overviewed, in order to gain insight into the features of both antitumoral and protumoral tumor-associated neutrophils (TAN). Neutrophils can counteract the progression of malignancies through tumor cytotoxicity, tumor rejection and enhancement of antitumoral immune memory. These cells have recently been phenotypically denominated N1 neutrophils. Recent studies indicate that cytokines, such as TGF-β and IFN-β, are involved in directing neutrophil polarization by the tumor microenvironment. With the opposite polarity, N2 neutrophils may be detrimental for the host and beneficial for tumor growth, invasion and metastasis, e.g. through proteolysis of extracellullar matrix components, promotion of angiogenesis and mediation of immunosuppression.

In many different tumor entities, increased expression of tissue inhibitor of metalloproteinases-1 (Timp-1) is associated with poor prognosis. We previously reported in mouse models that elevated systemic levels of Timp-1 induce a gene expression signature in the liver microenvironment increasing the susceptibility of this organ to tumor cells. This host effect was dependent on increased activity of the hepatocyte growth factor (Hgf)/hepatocyte growth factor receptor (Met) signaling pathway. In a recent study we showed that Met signaling is regulated by Timp-1 as it inhibits the Met sheddase A disintegrin and metalloproteinase-10 (Adam-10). The aim of the present study was to elucidate whether the metastatic potential of tumor cells benefits from autocrine Timp-1 as well and involves Adam-10 and Met signaling. In a syngeneic murine model of experimental liver metastasis Timp-1 expression and Met signaling were localized within metastatic colonies and expressed by tumor cells. Knock down of tumor cell Timp-1 suppressed Met signaling in metastases and inhibited metastasis formation and tumor cell-scattering in the liver. In vitro, knock down of tumor cell Timp-1 prevented Hgf-induced Met phosphorylation. Consequently, knock down of Met sheddase Adam-10 triggered auto-phosphorylation and responsiveness to Hgf. Accordingly, Adam-10 knock down increased Met phosphorylation in metastatic foci and induced tumor cell scattering into the surrounding liver parenchyma. In conclusion, these findings show that tumor cell-derived Timp-1 acts as a positive regulator of the metastatic potential and support the concept that proteases and their natural inhibitors, as members of the protease web, are major players of signaling during normal homeostasis and disease.

Abstract
The "protease web", representing the network of proteases, their inhibitors, and effector molecules, arises as a pivotal determinant of tissue homeostasis. Imbalances of this network, for instance caused by elevated host levels of tissue inhibitor of metalloproteinases-1 (TIMP-1), have been shown to increase the susceptibility of target organs to scattered metastasis by inducing the hepatocyte growth factor (HGF) pathway. Increased expression of the hypoxia-inducible factor-1α-subunit (HIF-1α) is also associated with tumour progression and is also known to induce HGF-signaling via up-regulation of the HGF-receptor Met, namely under canonical stress conditions like lack of oxygen. Here, we aimed to identify a possible metastasis-promoting connection between TIMP-1, HIF-1α, and HGF-signaling. We found that HIF-1α and HIF-1-signaling were increased during liver metastasis of L-CI.5s T-lymphoma cells in TIMP-1 overexpressing syngeneic DBA/2 mice. In vitro, exposure of L-CI.5s cells to recombinant TIMP-1 revealed that TIMP-1 itself was able to induce HIF-1α and HIF-1-signaling. Knock-down of HIF-1α identified tumour cell-derived HIF-1α as mediator of this TIMP-1-induced invasiveness in vitro. In vivo, HIF-1α knock-down significantly impaired Met expression as well as Met phosphorylation and inhibited scattered liver metastasis. Furthermore, HGF-dependent TIMP-1-promoted Met phosphorylation and HGF-dependent TIMP-1-induced invasiveness in vitro was mediated by HIF-1α. We conclude that elevated levels of TIMP-1 in the microenvironment of tumour cells can promote metastasis by inducing HIF-1α-dependent HGF-signaling. This connection between a protease inhibitor (TIMP-1) and a classically stress-related factor (HIF-1α) is a so far undiscovered impact of the "protease web" on tissue homeostasis with important implications for metastasis.
