Abstract
Although serious ocular manifestations of systemic sclerosis (SSc) have been described, tear analysis of patients with SSc has not been performed in previous studies. Our aim was to measure a wide panel of cytokines and chemokines in tears of patients with SSc and to assess the most significant molecules with a more sensitive and specific method. Unstimulated tear samples were collected from nine patients with SSc and 12 age- and gender-matched healthy controls. The relative levels of 102 different cytokines were determined by a cytokine array, and then absolute levels of four key cytokines were determined by a magnetic bead assay. Array results revealed shifted cytokine profile characterized by predominance of inflammatory mediators. Of the 102 analyzed molecules, nine were significantly increased in tears of patients with SSc. Based on the multiplex bead results, C-reactive protein, interferon-γ-inducible protein-10, and monocyte chemoattractant protein-1 levels were significantly higher in tears of patients with SSc. Our current data depict a group of inflammatory mediators, which play a significant role in ocular pathology of SSc; furthermore, they might function as excellent candidates for future therapeutic targets in SSc patients with ocular manifestations.

Abstract
Ras-association domain family 6 (RASSF6), a member of the RASSF family, is frequently downregulated in various types of cancer. However, the roles of RASSF6 in human hepatocellular carcinoma (HCC) are still unclear. In this study, we investigated the biological functions and related molecular mechanisms in HCC. Our results found that RASSF6 is expressed in low amounts in HCC tissues and cell lines. Overexpression of RASSF6 obviously inhibited the proliferation, invasion, and EMT process in HCC cells. Furthermore, overexpression of RASFF6 greatly downregulated the protein levels of phosphorylated focal adhesion kinase (FAK), MMP-2, and MMP-9 in HepG2 cells. Last, overexpression of RASFF6 significantly attenuated tumor growth in Balb/c nude mice. In conclusion, the present study revealed that RASFF6 can inhibit the proliferation, invasion, and migration of HCC cells both in vivo and in vitro. These inhibitory effects are through suppressing FAK phosphorylation, leading to decreased MMP-2/9 expression. RASFF6 is therefore a potential therapeutic target for treating HCC.

Ethanol extract of Lophatheri Herba exhibits anti-cancer activity in human cancer cells by suppression of metastatic and angiogenic potential. Sci Rep 2016; 6:36277. [PMID: 27808120 PMCID: PMC5093764 DOI: 10.1038/srep36277] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2016] [Accepted: 10/13/2016] [Indexed: 12/24/2022] Open
Abstract
Lophatheri Herba (LH), dried leaf of Lophatherum gracile Brongn, has long been used to reduce thirst and treat fever and inflammation in Chinese medicine. Recent studies have shown that LH has anti-viral, anti-bacterial, anti-cancer, anti-oxidant, diuretic, and hyperglycemic properties. However, the effects of an ethanol extract of L. herba (ELH), at non-cytotoxic doses, on the metastatic and angiogenic abilities of malignant tumor cells have not been reported. We found that ELH significantly suppressed p38, JNK, and NF-κB activation and proteolytic activities under phorbol 12-myristate 13-acetate (PMA) stimulation, thus leading to a decrease in metastatic potential, including migration and invasion. In addition, ELH suppressed tumor-induced angiogenesis, including migration and tube formation in human umbilical vein endothelial cells (HUVECs) and microvessel sprouting from aortic rings via decreasing the pro-angiogenic factors in tumors. Interestingly, in ovo xenografts ELH-treated HT1080 cells did not increase in volume and eventually disappeared, owing to a lack of angiogenesis. Daily oral administration of ELH at 50 and 100 mg/kg markedly inhibited metastatic colonization of B16F10 cells in the lungs of C57BL/6J mice and caused no apparent side effects. These data collectively indicate that ELH is safe and may be useful for managing metastasis and growth of malignant cancers.

Abstract
Gardeniae Fructus (GF, Zhi Zi in China), a fruit of Gardenia jasminoides Ellis, has been used in traditional medicine to reduce inflammation and headache and to treat hepatic disorders, hypertension, and icterus. In recent studies, extract of raw or stir-baked GF was shown to have pharmacological activities for viral infection, thrombosis, hyperlipidemia, convulsion, inflammation, oxidative stress, and others. In addition, baked GF extract suppressed the proteolytic activities and altered the cellular morphology of tumor cells. However, the effects of ethanol extract of baked GF (EBGF) on the metastatic and angiogenic capacities of malignant tumor cells and its detailed mechanism of action have not been reported. In this study, we found that EBGF significantly inhibited phorbol 12-myristate 13-acetate (PMA)-induced MMP-9 and -13 and uPA expression via suppression of PMA-induced nuclear translocation of NF-κBp65. Metastatic potential, including migration, invasion, and colonization, was substantially reduced by EBGF with no cytotoxicity. In addition, EBGF attenuated tumor-induced angiogenesis, including microvessel sprouting, migration of endothelial cells (ECs), and tube formation of ECs, by inhibiting the release of pro-angiogenic factors from tumor cells. In C57BL/6 mice, we observed that daily administration of EBGF at 50 and 100 mg/kg suppressed metastatic colonization of B16F10 melanoma cells in the lungs. Furthermore, EBGF administration did not cause adverse effects, suggesting that EBGF is safe and may be a potential herbal medicine capable of controlling metastatic malignant cancers.

Abstract
Adaptation to hypoxia is an important process physiologically and pathologically. Hypoxia-inducible factor-1α (HIF-1α) participates in the cancer biology of numerous endocrine tumors, including their proliferation and differentiation. In the present study, the hypothesis that HIF-1α promotes tumorigenesis in thyroid cancer via upregulating angiogenesis-associated markers is investigated. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analysis were used to examine the expression of HIF-1α in thyroid cancer cell lines, and to detect the expression of WW domain containing E3 ubiquitin protein ligase (WWP)2, WWP9, vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR2) in MZ-CRC-1 and TT thyroid cancer cells. Cell proliferation was measured using a Cell Count Kit-8. Cell apoptosis and cell cycle was assessed by flow cytometry. Cell invasive ability was examined by Matrigel transwell analysis. RT-qPCR and western blot analyses demonstrated that the mRNA and protein expression levels of HIF-1α were significant higher in MZ-CRC-1 and TT thyroid cancer cells than in another three thyroid cancer cells (P<0.01). HIF-1α knockdown cells demonstrated inhibition of cell proliferation and invasion, arrested cell cycle at the G1 phase, and induction of cell apoptosis. The protein expression levels of WWP2, WWP9, VEGF and VEGFR2 were decreased in HIF-1α knockdown MZ-CRC-1 and TT cells. In conclusion, HIF-1α may be important in cell apoptosis and invasion of thyroid cancer cells, likely through regulating WWP2, WWP9, VEGF and VEGFR2 expression.

Abstract
Context Simvastatin (SV) and bergamottin (BGM) are known to exhibit diverse anti-cancer and anti-inflammatory activities. Objective Very little is known about the potential efficacy of combination of these two agents to potentiate TNF-induced apoptosis in human chronic myelogenous leukaemia (CML). Materials and methods In the present study, we investigated whether SV combined with BGM mediates its effect through suppression of NF-κB-signalling pathway. Results We found that the combination treatment enhanced cytotoxicity and potentiated the apoptosis induced by TNF as indicated by intracellular esterase activity, Annexin V staining and caspase activation. This effect of co-treatment correlated with down-regulation of various gene products that mediate cell proliferation (cyclin D1), cell survival (cIAP-1, Bcl-2, Bcl-xL and Survivin), invasion (MMP-9) and angiogenesis (VEGF); all known to be regulated by NF-κB. SV combined with BGM also produced TNF-induced cell-cycle arrest in S-phase and this arrest correlated with a concomitant increase in the levels of cyclin-dependent inhibitor p21 and p27. The combination therapy inhibited TNF-induced NF-κB activation, IκBα degradation and p65 translocation to the nucleus as compared with the treatment with individual agents alone. Besides, SV combined with BGM did not significantly potentiate apoptotic effect induced by TNF in p65(-)(/)(-) cells, as compared with wild-type fibroblasts. Discussion and conclusion Our results provide novel insight into the role of SV and BGM in potentially preventing and treating cancer through modulation of NF-κB signalling pathway and its regulated gene products.

Abstract
Supplemental digital content is available in the text. Objective The aim of this study is to investigate the clinicopathologic significance and potential role of metastasis-associated in colon cancer-1 (MACC1) in the progression of cervical cancer. Methods MACC1 expression was examined in cervical cancer cell lines, 6 matched cervical cancer tissues, and adjacent noncancerous tissues using Western blotting and real-time reverse transcriptase polymerase chain reaction. MACC1 protein expression and localization were determined in 181 paraffin-embedded archived cervical cancer samples using immunohistochemistry. Statistical analyses were applied to evaluate the clinicopathologic significance. The effects of MACC1 on cell migration, invasion, and angiogenesis were examined using migration assay, wound healing assay, 3-dimensional morphogenesis assay, and chicken chorioallantoic membrane assay. Western blotting was performed to examine the impact of MACC1 on the Akt and nuclear factor κB signaling pathways. Results Both protein and messenger RNA levels of MACC1 was up-regulated in cervical cancer cell lines and cervical cancer tissues, as compared with normal tissues. High MACC1 expression was detected in 96 (53%) of 181 of the cervical cancer tissues. In addition, high MACC1 expression correlated significantly with aggressiveness of cervical cancer, including International Federation of Gynecology and Obstetric stage (P = 0.001), pelvic lymph node metastasis (P = 0.004), recurrence (P = 0.037), and poor survival (P = 0.001). Moreover, enforced expression of MACC1 in cervical cancer cell lines significantly enhanced cell migration, invasion, and angiogenesis. Conversely, knockdown of MACC1 caused an inhibition of cell migration, invasion, and angiogenesis. Up-regulation of MACC1 increased, but knockdown of MACC1 decreased the expression of matrix metalloproteinase-2 and matrix metalloproteinase-9. Furthermore, enforced expression of MACC1 could enhance, but knockdown of MACC1 could reduce AKT and nuclear factor κB pathway activity. Conclusions Our findings suggest that MACC1 protein, as a valuable marker of cervical cancer prognosis, plays an important role in the progression of human cervical cancer cells.

Abstract
OBJECTIVE Hypercholesterolemia is one of the well-established risk factors for cardiovascular mortality and morbidity in coronary heart disease. The aim of this study was to investigate the anti-atherogenic effect of Chungtaejeon (CTJ, a Korean fermented tea) aqueous extract on proliferation and migration of human aortic smooth muscle cells (HASMCs) in vivo and in vitro. METHODS The authors used high-fat atherogenic diet (HFAD) to induce hyperlipidemia in Wistar rats in in vivo animal experiments and used HASMCs for in vitro cell experiments. For the in vitro cell experiment, the proliferation of HASMCs was evaluated using the MTT assay. Similarly, the expression of matrix metalloproteinases (MMPs) in HASMCs was measured using gelatin zymography. Antimigratory activity of CTJ was revealed using the wound-healing model and Boyden 's chamber assay. In the in vivo experiment, CTJ was administered in three different doses for 20 d from the initiation of the HFAD. After 20 d, the serum lipid profile and total lipid contents in liver were measured. RESULTS Treatment with CTJ for 24 h dose-dependently inhibited the proliferation and migration of HASMCs and expression of MMP-2 in HASMCs. The oral administration of CTJ at concentrations of 200 and 400 mg/kg decreased the levels of low-density lipoprotein cholesterol, total serum cholesterol and hepatic cholesterol of HFAD-fed rats. CONCLUSION CTJ possessed strong antiproliferative, antimigratory, as well as lipid-lowering activities. Thus, CTJ can be considered as a therapeutic option in the treatment of high-fat diet-induced atherosclerosis.

Abstract
Peritoneal metastasis is a primary cause of mortality in patients with gastric cancer. Urokinase-type plasminogen activator (uPA) has been demonstrated to be associated with tumor cell metastasis through the degradation of the extracellular matrix. The present study aimed to investigate the mechanisms of the uPA system in gastric cancer with peritoneal metastasis. Expression of uPA, uPA receptor (uPAR) and plasminogen activator inhibitor-1 (PAI-1) in four gastric cell lines (AGS, SGC7901, MKN45 and MKN28) was measured by semiquantitative reverse transcription polymerase chain reaction, enzyme-linked immunosorbent assay and western blotting. uPA activity was detected using a uPA activity kit. Peritoneal implantation models of rats were established by injecting four gastric cancer cell lines for the selection of the cancer cells with a high planting potential. Biological behaviors, including adhesion, migration and invasion, were determined using a methyl thiazolyl tetrazolium assay. Expression of the uPA system was observed to be highest in the SGC7901 cells among the four gastric cell lines. uPA activity was observed to be highest in the MKN45 cells and lowest in the AGS cells. Furthermore, peritoneal implantation analysis demonstrated that no peritoneal tumors were identified in the AGS cells, whilst the tumor masses observed in the SGC7901 and MKN45 cells were of different sizes. The survival times of the rats injected with the MKN28 and SGC7901 cells were longer than those of the rats injected with the MKN45 cells. Antibodies for uPA, uPAR and PAI-1 in the uPA system had the ability to inhibit the adhesion, migration and invasion of peritoneal metastasis in the gastric cancer cells. The results of the present study demonstrated that the uPA system was positively associated with peritoneal metastasis in gastric cancer.

Extracellular Visfatin-Promoted Malignant Behavior in Breast Cancer Is Mediated Through c-Abl and STAT3 Activation. Clin Cancer Res 2016; 22:4478-90. [PMID: 27036136 DOI: 10.1158/1078-0432.ccr-15-2704] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2015] [Accepted: 03/22/2016] [Indexed: 11/16/2022]
Abstract
PURPOSE Visfatin is an adipocytokine involved in cellular metabolism, inflammation, and cancer. This study investigated the roles of extracellular visfatin in breast cancer, and explored underlying mechanisms in clinical and experimental settings. EXPERIMENTAL DESIGN Associations of serum visfatin with clinicopathologic characteristics and patient survival were assessed with Cox regression models and Kaplan-Meier analyses. Effects of extracellular visfatin on cultured breast cancer cells were examined, followed by in vivo investigation of tumor growth and metastasis in xenograft animal models. Imatinib and Stattic were used to inhibit c-Abl and STAT3 activation, respectively. RESULTS Breast cancer patients with high serum visfatin levels were associated with advanced tumor stage, increased tumor size and lymph node metastasis, and poor survival. Elevated phosphorylation of c-Abl and STAT3 in breast tumor tissues were correlated with high serum visfatin levels in patients. Visfatin-promoted in vitro cell viability and metastatic capability were suppressed by imatinib (c-Abl inhibitor) and Stattic (STAT3 inhibitor). Increased in vivo cell invasiveness was observed in zebrafish xenografted with visfatin-pretreated breast cancer cells. Tumor growth and lung metastasis occurred in visfatin-administered mice xenografted with breast cancer cells. Tail vein-injected mice with visfatin-pretreated breast cancer cells showed increased lung metastasis, which was suppressed by imatinib. CONCLUSIONS Serum visfatin levels in breast cancer patients reveal potential prognostic values, and our findings that visfatin promoted breast cancer through activation of c-Abl and STAT3 may provide an important molecular basis for future design of targeted therapies that take into account different serum visfatin levels in breast cancer.

Overexpression of angiotensin II type 1 receptor in breast cancer cells induces epithelial-mesenchymal transition and promotes tumor growth and angiogenesis. BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR CELL RESEARCH 2016; 1863:1071-81. [PMID: 26975580 DOI: 10.1016/j.bbamcr.2016.03.010] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2015] [Revised: 02/15/2016] [Accepted: 03/10/2016] [Indexed: 01/10/2023]
Abstract
The angiotensin II type I receptor (AGTR1) has been implicated in diverse aspects of human disease, from the regulation of blood pressure and cardiovascular homeostasis to cancer progression. We sought to investigate the role of AGTR1 in cell proliferation, epithelial-mesenchymal transition (EMT), migration, invasion, angiogenesis and tumor growth in the breast cancer cell line MCF7. Stable overexpression of AGTR1 was associated with accelerated cell proliferation, concomitant with increased expression of survival factors including poly(ADP-ribose) polymerase (PARP) and X-linked inhibitor of apoptosis (XIAP), as well as extracellular signal-regulated kinase (ERK) activation. AGTR1-overexpressing MCF7 cells were more aggressive than their parent line, with significantly increased activity in migration and invasion assays. These observations were associated with changes in EMT markers, including reduced E-cadherin expression and increased p-Smad3, Smad4 and Snail levels. Treatment with the AGTR1 antagonist losartan attenuated these effects. AGTR1 overexpression also accelerated tumor growth and increased Ki-67 expression in a xenograft model. This was associated with increased tumor angiogenesis, as evidenced by a significant increase in microvessels in the intratumoral and peritumoral areas, and enhanced tumor invasion, with the latter response associated with increased EMT marker expression and matrix metallopeptidase 9 (MMP-9) upregulation. In vivo administration of losartan significantly reduced both tumor growth and angiogenesis. Our findings suggest that AGTR1 plays a significant role in tumor aggressiveness, and its inhibition may have therapeutic implications.

Abstract
Fatty acid binding protein 5 (FABP5), an intracellular lipid binding protein, has been shown to play a role in various cancers, including breast cancer. However, FABP5 and its role in triple negative breast cancer (TNBC) have not been studied. We show FABP5 protein expression correlates with TNBC, high grade tumors, and worse disease-free survival in a tissue microarray containing 423 breast cancer patient samples. High FABP5 expression significantly correlates with epidermal growth factor receptor (EGFR) expression in these samples. Decreased tumor growth and lung metastasis were observed in FABP5-/- mice othotopically injected with murine breast cancer cells. FABP5 loss in TNBC tumor cells inhibited motility and invasion. Mechanistic studies revealed that FABP5 knockdown in TNBC cells results in decreased EGFR expression and FABP5 is important for EGF-induced metastatic signaling. Loss of FABP5 leads to proteasomal targeting of EGFR. Our studies show that FABP5 has a role in both host and tumor cell during breast cancer progression. These findings suggest that FABP5 mediates its enhanced effect on TNBC metastasis, in part, through EGFR, by inhibiting EGFR proteasomal degradation. These studies show, for the first time, a correlation between FABP5 and EGFR in enhancing TNBC metastasis through a novel mechanism.

Abstract
Recent studies suggest that paired box 5 (PAX5) is down‐regulated in multiple tumours through its promoter methylation. However, the role of PAX5 in non‐small cell lung cancer (NSCLC) pathogenesis remains unclear. The aim of this study is to examine PAX5 expression, its methylation status, biological functions and related molecular mechanism in NSCLC. We found that PAX5 was widely expressed in normal adult tissues but silenced or down‐regulated in 88% (7/8) of NSCLC cell lines. PAX5 expression level was significantly lower in NSCLC than that in adjacent non‐cancerous tissues (P = 0.0201). PAX5 down‐regulation was closely associated with its promoter hypermethylation status and PAX5 expression could be restored by demethylation treatment. Frequent PAX5 promoter methylation in primary tumours (70%) was correlated with lung tumour histological types (P = 0.006). Ectopic expression of PAX5 in silenced lung cancer cell lines (A549 and H1975) inhibited their colony formation and cell viability, arrested cell cycle at G2 phase and suppressed cell migration/invasion as well as tumorigenicity in nude mice. Restoration of PAX5 expression resulted in the down‐regulation of β‐catenin and up‐regulation of tissue inhibitors of metalloproteinase 2, GADD45G in lung tumour cells. In summary, PAX5 was found to be an epigenetically inactivated tumour suppressor that inhibits NSCLC cell proliferation and metastasis, through down‐regulating the β‐catenin pathway and up‐regulating GADD45G expression.

Abstract
Tumor neovascularization acquires their vessels through a number of processes including angiogenesis, vasculogenesis, vascular remodeling, intussusception, and possibly vascular mimicry in certain tumors. The end result of the tumor vasculature has been quantified by counting the number of immunohistochemically identified microvessels in areas of maximal vascularity, so-called hot spot. Other techniques have been developed such as Chalkley counting and the use of image analysis systems that are robust and reproducible as well as being more objective. Many of the molecular pathways that govern tumor neovascularization have been identified and many reagents are now available to study these tissue sections. These include angiogenic growth factors and their receptors and cell adhesion molecules, proteases, and markers of activated, proliferating, cytokine-stimulated, or angiogenic vessels, such as CD105. It is also possible to differentiate quiescent from active vessels. Other reagents that can identify proteins involved in microenvironmental influences such as hypoxia have also been generated. Although the histological assessment of tumor vascularity is used mostly in the research context, it may also have clinical applications if appropriate methodology and trained observers perform the studies.

Black Rice Anthocyanins Suppress Metastasis of Breast Cancer Cells by Targeting RAS/RAF/MAPK Pathway. BIOMED RESEARCH INTERNATIONAL 2015; 2015:414250.

Abstract
Overexpression of human epidermal growth factor receptor 2 (HER2) drives the biology of 30% of breast cancer cases. As a transducer of HER2 signaling, RAS/RAF/MAPK pathway plays a pivotal role in the development of breast cancer. In this study, we examined the molecular mechanisms underlying the chemopreventive effects of black rice anthocyanins (BRACs) extract and identified their molecular targets in HER2(+) breast cancer cells. Treatment of MDA-MB-453 cells (HER2(+)) with BRACs inhibited cell migration and invasion, suppressed the activation of mitogen-activated protein kinase kinase kinase (RAF), mitogen-activated protein kinase kinase (MEK), and c-Jun N-terminal kinase (JNK), and downregulated the secretion of matrix metalloproteinase 2 (MMP2) and MMP9. BRACs also weakened the interactions of HER2 with RAF, MEK, and JNK proteins, respectively, and decreased the mRNA expression of raf, mek, and jnk. Further, we found combined treatment with BRACs and RAF, MEK, or JNK inhibitors could enhance the antimetastatic activity, compared with that of each treatment. Transient transfection with small interfering RNAs (siRNAs) specific for raf, mek, and jnk inhibited their mRNA expression in MDA-MB-453 cells. Moreover, cotreatment with BRACs and siRNA induces a more remarkable inhibitory effect than that by either substance alone. In summary, our study suggested that BRACs suppress metastasis in breast cancer cells by targeting the RAS/RAF/MAPK pathway.

Abstract
MMP-9 (92 kDa gelatinease), which is member of matrix metalloproteinases (MMPs) family, plays a crucial role in the breakdown of extracellular matrix (ECM) by degrading the major components of ECM that lead to tumor cell invasion and metastasis through the basement membrane. Our study presents the on-chip dual-sensing device for rapid detection of cell-secreted MMP-9 and corresponding cell morphology changes in real-time domain. The device consists of 2 sensing platforms (both are interdigitated array microelectrodes - IDAMs) within 1 common fluidic chamber: one detects the cell morphology responses via Electric Cell-substrate Impedance Sensing (ECIS) technique, meanwhile the other records the cleavage effect between cell-secreted MMP-9 and the surface immobilized peptide via the capacitance-based sensing method. Thanks to the selectivity of designed peptide, this approach allows the rapid and specific detection of MMP-9. In comparison with gold standard ELISA assay, the detection time was significantly reduced from over 4h to within 30 min with the wide detection range from 10 pM to 10nM. Finally, this study provides the novel model for MMP-9 protease direct detection from living cell and new insights in multi-purpose detection of cancer associated enzyme and cell migration behavior.

Abstract
Osteosarcoma is the most frequent primary malignant bone tumor that occurs in children and adolescents. The present study aimed to identify novel therapeutic strategies for osteosarcoma, by assessing the antitumor activity of the cannabinoid WIN-55,212-2 and its combined effect with adriamycin (ADM) against the MG-63 human osteosarcoma cell line. To evaluate the antiproliferative action of these molecules, a Cell Counting kit-8 (CCK-8) assay was used. The ability of cannabinoid to inhibit the migration, invasion and angiogenic activity of MG-63 cells were assessed by scratch, Transwell® chamber and angiogenesis assays, respectively, in vitro. To examine the alterations in expression of targeted genes, quantitative polymerase chain reaction and western blot analysis were used. The administration of cannabinoid combined with ADM was demonstrated to inhibit the growth of MG-63 cells, resulting in a cell viability of 32.12±3.13%, which was significantly lower (P<0.05) compared with the cell viability following treatment with cannabinoid (70.86±7.55%) and ADM (62.87±5.98%) alone. Greater antimetastasis and antiangiogenic activities were also observed following the coadministration of the two agents compared with individual treatments and controls. In addition, the expression levels of Notch-1, matrix metalloproteinase-2 (MMP-2) and vascular endothelial growth factor (VEGF) in MG-63 cells were downregulated following the treatments with cannabinoid alone or in combination with ADM. In conclusion, the present findings demonstrated that cannabinoid WIN-55,212-2 may significantly potentiate the antiproliferative, antimetastasis and antiangiogenic effects of ADM against MG-63 cells via the downregulation of Notch-1, MMP-2 and VEGF. These findings may offer a novel strategy for the treatment of osteosarcoma.

The Mesothelial Origin of Carcinoma Associated-Fibroblasts in Peritoneal Metastasis. Cancers (Basel) 2015; 7:1994-2011.

Abstract
Solid tumors are complex and unstructured organs that, in addition to cancer cells, also contain other cell types. Carcinoma-associated fibroblasts (CAFs) represent an important population in the tumor microenviroment and participate in several stages of tumor progression, including cancer cell migration/invasion and metastasis. During peritoneal metastasis, cancer cells detach from the primary tumor, such as ovarian or gastrointestinal, disseminate through the peritoneal fluid and colonize the peritoneum. Tumor cells metastasize by attaching to and invading through the mesothelial cell (MC) monolayer that lines the peritoneal cavity, then colonizing the submesothelial compact zone where CAFs accumulate. CAFs may derive from different sources depending on the surrounding metastatic niche. In peritoneal metastasis, a sizeable subpopulation of CAFs originates from MCs through a mesothelial-to-mesenchymal transition (MMT), which promotes adhesion, invasion, vascularization and subsequent tumor growth. The bidirectional communication between cancer cells and MC-derived CAFs via secretion of a wide range of cytokines, growth factors and extracellular matrix components seems to be crucial for the establishment and progression of the metastasis in the peritoneum. This manuscript provides a comprehensive review of novel advances in understanding how peritoneal CAFs provide cancer cells with a supportive microenvironment, as well as the development of future therapeutic approaches by interfering with the MMT in the peritoneum.

Abstract
NF-κB comprises a family of five transcription factors that form distinct protein complexes, which bind to consensus DNA sequences at promoter regions of responsive genes regulating cellular processes. The past three decades have witnessed remarkable progress in understanding the NF-κB signaling pathway in physiologic and pathologic conditions. The role of NF-κB in human cancer initiation, development, metastasis, and resistance to treatment has drawn particular attention. A significant number of human cancers have constitutive NF-κB activity due to the inflammatory microenvironment and various oncogenic mutations. NF-κB activity not only promotes tumor cells' proliferation, suppresses apoptosis, and attracts angiogenesis, but it also induces epithelial-mesenchymal transition, which facilitates distant metastasis. In certain circumstances, NF-κB activation may also remodel local metabolism and anergize the immune system to favor tumor growth. Suppression of NF-κB in myeloid cells or tumor cells usually leads to tumor regression, which makes the NF-κB pathway a promising therapeutic target. However, because of its vital role in various biologic activities, components of the NF-κB pathway need to be carefully selected and evaluated to design targeted therapies.

Abstract
Ultraviolet B (UVB) irradiation may cause inflammation- and oxidative-stress-dependent skin cancer and premature aging. Naringenin (1) has been reported to have anti-inflammatory and antioxidant properties, but its effects and mechanisms on UVB irradiation-induced inflammation and oxidative stress are still not known. Thus, the present study aimed to investigate the potential of naringenin to mitigate UVB irradiation-induced inflammation and oxidative damage in the skin of hairless mice. Skin edema, myeloperoxidase (neutrophil marker) and matrix metalloproteinase-9 (MMP-9) activity, and cytokine production were measured after UVB irradiation. Oxidative stress was evaluated by 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS) scavenging ability, ferric reducing antioxidant power (FRAP), reduced glutathione levels, catalase activity, lipid peroxidation products, superoxide anion production, and gp91phox (NADPH oxidase subunit) mRNA expression by quantitative PCR. The intraperitoneal treatment with naringenin reduced skin inflammation by inhibiting skin edema, neutrophil recruitment, MMP-9 activity, and pro-inflammatory (TNF-α, IFN-γ, IL-1β, IL-4, IL-5, IL-6, IL-12, IL-13, IL-17, IL-22, and IL-23) and anti-inflammatory (TGF-β and IL-10) cytokines. Naringenin also inhibited oxidative stress by reducing superoxide anion production and the mRNA expression of gp91phox. Therefore, naringenin inhibits UVB irradiation-induced skin damage and may be a promising therapeutic approach to control skin disease.

Abstract
OBJECTIVE Cyclic-AMP-responsive element-binding protein (CREB) is a proto-oncogenic transcription factor. The authors' previous reports showed that blocking the CREB binding site at Ser 133 inhibited the expression of target genes, which related to the progression of some tumors. In this study, the authors investigated the role of phosphorylated CREB (pCREB) at Ser133 in renal cell carcinoma (RCC) growth and metastases. METHODS Immunohistochemistry, xenograft model in nude mice, cell proliferation assay, cell invasion/migration assay, fluorescent immunocytochemistry and Western analysis were performed in an immortalized proximal tubule epithelial cell line and clear-cell RCC. RESULTS The authors' results showed that knockdown of pCREB inhibited kidney cancer cells growth in vivo. Furthermore, suppression of the pCREB level blunted the capabilities of cell migration and invasion in vitro and was accompanied with significantly decreased expression of MMP-2 and MMP-9, the filopodia formation and epithelial-mesenchymal transition-related proteins. Surprisingly, no changes of expression or location of vimentin were revealed in the experiment. Bioinformatic software explained the possible reason for this is that the promoter of vimentin does not contain the CRE sequence. CONCLUSIONS These data suggest that decreasing the level of pCREB inhibits the growth and metastasis of RCC by targeting the Ser 133 site.

Abstract
Targeted drug delivery has been the major topic in drug formulation and delivery. As nanomedicine emerges to create nano scale therapeutics and diagnostics, it is still essential to embed targeting capability to these novel systems to make them useful. Here we discuss various targeting approaches for delivery of therapeutic and diagnostic nano materials in view of search for more universal methods to target diseased tissues. Many diseases are accompanied with hypoxia and acidosis. Coating nanoparticles with pH Low Insertion Peptides (pHLIPs) increases efficiency of targeting acidic diseased tissues. It has been showing promising results to create future nanotheranostics for cancer and other diseases which are dominating in the present world.

Abstract
Ovarian cancer is the leading cause of death from gynecologic malignancies. One of the reasons for the high mortality rate associated with ovarian cancer is its late diagnosis, which often occurs after the cancer has metastasized throughout the peritoneal cavity. Cancer metastasis is facilitated by the remodeling of the extracellular tumor matrix by a family of proteolytic enzymes known as the matrix metalloproteinases (MMPs). There are 23 members of the MMP family, many of which have been reported to be associated with ovarian cancer. In the current paradigm, ovarian tumor cells and the surrounding stromal cells stimulate the synthesis and/or activation of various MMPs to aid in tumor growth, invasion, and eventual metastasis. The present review sheds light on the different MMPs in the various types of ovarian cancer and on their impact on the progression of this gynecologic malignancy.

Abstract
The aim of the present study was to use genetic engineering in order to establish an efficient tumor necrosis factor (TNF)-α fusion protein with low toxicity, which may be used to target tumors. Four types of matrix metalloproteinase (MMP)-mediated tumor targeting human recombinant TNF-α (rhTNF-α) fusion protein vectors were constructed. These were subsequently introduced into Escherichia coli. rhTNF-α fusion protein with a glutathione S-transferase (GST)-tag was purified using GST resin affinity chromatography, and GST-tags were digested using factor Xa. The cytotoxic effects of the fusion protein on L929 cells were determined using MTT assays. At a concentration of 1 pM, the GST-tagged fusion protein exerted no cytotoxic effects on the cells, compared with the negative control cells (P=0.975>0.05). However, at a concentration of 1000 pM, the deblocking fusion protein exerted greater cytotoxic effects on L929 cells, compared with positive control cells (P<0.05). Treatment with the fusion protein also induced cell apoptosis in the nasopharyngeal cancer cell line, CNE-2Z, which secretes high levels of MMP-1. In conclusion, the results of the present study suggested that MMP-mediated rhTNF-α fusion protein induces CNE-2Z cells apoptosis. rhTNF-α exhibits high efficacy and tumor cell targeting capability, with low toxicity effects on healthy cells.

Abstract
The progression of multiple myeloma (MM) is governed by a network of molecular signals, the majority of which remain to be identified. Recent studies suggest that Runt-related transcription factor 2 (Runx2), a well-known bone-specific transcription factor, is also expressed in solid tumors, where expression promotes both bone metastasis and osteolysis. However, the function of Runx2 in MM remains unknown. The current study demonstrated that (1) Runx2 expression in primary human MM cells is significantly greater than in plasma cells from healthy donors and patients with monoclonal gammopathy of undetermined significance; (2) high levels of Runx2 expression in MM cells are associated with a high-risk population of MM patients; and (3) overexpression of Runx2 in MM cells enhanced tumor growth and disease progression in vivo. Additional studies demonstrated that MM cell-derived Runx2 promotes tumor progression through a mechanism involving the upregulation of Akt/β-catenin/Survivin signaling and enhanced expression of multiple metastatic genes/proteins, as well as the induction of a bone-resident cell-like phenotype in MM cells. Thus, Runx2 expression supports the aggressive phenotype of MM and is correlated with poor prognosis. These data implicate Runx2 expression as a major regulator of MM progression in bone and myeloma bone disease.

Abstract
PURPOSE Oropharyngeal cancer (OPC) is the eighth most common cancer worldwide, however the genes involved in the development of OPC have been reported few. We constructed a co-expression network to extend knowledge of the molecular biomarkers in OPC development. MATERIALS AND METHODS Microarray data of HPV-active, -inactive, -negative OPC and normal benign tissue (uvula, tonsil) (Series GSE55550) were retrieved from NCBI GEO DataSets. We performed co-expression analysis of OPC transcriptome data by the Pearson correlation coefficient (PCC) method with the mutual rank (MR)-based cut-off using 13 guide genes. RESULTS The OPC subnetwork contained three clusters: cell cycle (62 node genes and 125 edge genes), immune system (44 node genes and 70 edge genes) and organ morphogenesis (128 node gene and 215 edge genes) process separately. CONCLUSION Our co-expression analysis includes separated transcriptomes of OPC, which is a useful resource for OPC researchers to elucidate important and complex biological events, to prevent and to predict cancer.

β-Caryophyllene oxide potentiates TNFα-induced apoptosis and inhibits invasion through down-modulation of NF-κB-regulated gene products. Apoptosis 2015; 19:708-18.

Abstract
We have recently reported that β-caryophyllene oxide (CPO) can induce apoptosis, suppress tumor growth, and inhibit metastasis through the suppression of signal transducer and activator of transcription 3, PI3K/AKT/mTOR/S6K1 signaling cascades and ROS-mediated MAPKs activation. In the present study, we found that CPO potentiated the apoptosis induced by tumor necrosis factor α (TNFα) and chemotherapeutic agents, suppressed TNFα-induced tumor cell invasion, all of which are known to require NF-κB activation. We found that TNFα stimulated the expression of gene products involved in anti-apoptosis (IAP1, IAP2, Bcl-2, Bcl-xL, and survivin), proliferation (COX-2, cyclin D1, and c-Myc), invasion (MMP 9 and ICAM-1), and angiogenesis (VEGF) and that CPO treatment suppressed their expression. Because these gene products are also regulated by proinflammatory transcription factor NF-κB, we postulated that CPO may mediate its effects by modulating the NF-κB pathway. We found that CPO blocked both inducible and constitutive NF-κB activation in a wide variety of tumor cells. CPO was also found to inhibit the TNFα-induced degradation of IκBα through the inhibition of activation of IκBα kinase and p65 nuclear translocation and phosphorylation. Interestingly, CPO failed to potentiate the apoptotic effect induced by TNFα in p65 (-/-) cells as compared to the wild-type. Thus, overall, our results indicate that the inhibition of NF-κB is one of major mechanisms by which CPO enhances TNFα-induced apoptosis and suppresses invasion.

Abstract
Tumors are complex tissues that consist of stromal cells, such as fibroblasts, immune cells and mesenchymal stem cells, as well as non-cellular components, in addition to neoplastic cells. Increasingly, there is evidence to suggest that these non-neoplastic cell components support cancer initiation, progression and metastasis and that their ablation or reprogramming can inhibit tumor growth. Our understanding of the activities of different parts of the tumor stroma in advancing cancer has been improved by the use of scaffold and matrix-based 3D systems originally developed for regenerative medicine. Additionally, drug delivery systems made from synthetic and natural biomaterials deliver drugs to kill stromal cells or reprogram the microenvironment for tumor inhibition. In this article, we review the impact of 3D tumor models in increasing our understanding of tumorigenesis. We also discuss how different drug delivery systems aid in the reprogramming of tumor stroma for cancer treatment.

Abstract
BACKGROUND Lung cancer remains the leading cause of cancer-related death, largely owing to the lack of effective treatments. A tumour vascular targeting strategy presents an attractive alternative; however, the molecular signature of the vasculature in lung cancer is poorly explored. This work aimed to identify novel tumour vascular targets in lung cancer. METHODS Enzymatic digestion of fresh tissue followed by endothelial capture with Ulex lectin-coated magnetic beads was used to isolate the endothelium from fresh tumour specimens of lung cancer patients. Endothelial isolates from the healthy and tumour lung tissue were subjected to whole human genome expression profiling using microarray technology. RESULTS Bioinformatics analysis identified tumour endothelial expression of angiogenic factors, matrix metalloproteases and cell-surface transmembrane proteins. Predicted novel tumour vascular targets were verified by RNA-seq, quantitative real-time PCR analysis and immunohistochemistry. Further detailed expression profiling of STEAP1 on 82 lung cancer patients confirmed STEAP1 as a novel target in the tumour vasculature. Functional analysis of STEAP1 using siRNA silencing implicates a role in endothelial cell migration and tube formation. CONCLUSIONS The identification of cell-surface tumour endothelial markers in lung is of interest in therapeutic antibody and vaccine development.

Abstract
Local delivery of lipid mediators has become a promising new approach for therapeutic angiogenesis and regenerative medicine. In this study, we investigated how gradient stimulation (either abluminal/distal or luminal/proximal) of engineered microvessels with sphingosine 1-phosphate (S1P) receptor-subtype-targeted molecules affects endothelial sprout growth using a microfluidic device. Our studies show that distal stimulation of microvessels with FTY720, an S1P1/3 selective agonist, promotes both arterial and venular sprout growth, whereas proximal stimulation does not. Using novel pharmacological antagonists of S1P receptor subtypes, we further show that S1P3 functionality is necessary for VEGF-induced sprouting, and confirmed these findings ex vivo using a murine aortic ring assay from S1P3-deficient mice. S1P3 agonist stimulation enhanced vascular stability in both cell types via upregulation of the interendothelial junction protein VE-cadherin. Lastly, S1P3 activation under flow promoted endothelial sprouting and branching while decreasing migratory cell fate in the microfluidic device. We used an in vivo murine dorsal skinfold window chamber model to confirm S1P3's role in neovascular branching. Together, these data suggest that a distal transendothelial gradient of S1P1/3-targeted drugs is an effective technique for both enhancing and stabilizing capillary morphogenesis in angiogenic applications.

Abstract
Coetaneous malignant melanoma is the most aggressive cancer of the skin with a high rate of mortality worldwide. Degradation of basement membranes and extracellular matrix is an essential step in cancer invasion and metastasis. Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) play key roles in this step. MMP-3 also called stromelysin-1 was one of the first proteinases found to be associated with cancer. In the gene of MMP-3 (MMP3), an insertion/deletion of an A nucleotide at position -1171 in promoter region has been identified and shown to effect the expression activity of the gene. The present study was conducted to investigate the relation of MMP3 -1171insA polymorphism with skin malignant melanoma risk in a pilot case-control study of Bulgarian patients (n = 26) and unaffected controls (n = 172). The genotypes of controls and melanoma patients were in Hardy-Weinberg equilibrium. The results showed no statistically significant difference both in genotype and allele frequencies of MMP3 -1171insA polymorphism between melanoma patients and healthy controls either in crude analyses (p = 0.360 and 0.790, c2-test) or after adjustment for age and sex. The comparison of some clinical characteristics between the patients with different genotypes showed a trend for longer survival of patients with 6A/6A genotype compared to the carriers of 5A allele (5A/5A+5A/6A genotypes, p = 0.118, Log rank test). The results of our current preliminary study do not provide evidence for the role of the promoter polymorphism -1171insA in MMP3 as a risk factor for development of coetaneous melanoma, but suggest its implication in progression of the diseases.

Abstract
Malignant melanoma cells are known to have altered expressions of growth factors as compared with normal melanocytes. Thrombomodulin (TM) is a thrombin receptor on endothelial cells that converts thrombin from a procoagulant to an anticoagulant enzyme. TM expression is downregulated in tumor cells, and this phenomenon correlates with tumor cell invasiveness and a poor prognosis in patients with cancer. In this study, we evaluated TM expression in two human melanoma cell lines that are known to have either low (WM35) or high (A375) aggressive phenotypes. Analysis by quantitative real-time PCR (qPCR) showed that the mRNA expression of TM is modestly (WM35) or dramatically (A375) downregulated in melanoma cells, as compared with human primary melanocytes. TM expression levels inversely correlated with in-vitro migration properties of tumor cells. In addition, interleukin-8 expression also correlated with the degree of aggressiveness, as indicated by high expression levels of this cytokine in A375 cells. Overexpression of TM in A375 cells by transient transfection reversed their aggressive phenotype and dramatically decreased interleukin-8 expression by these cells. Taken together, these results suggest that downregulation of TM plays a crucial role in melanocyte transformation and melanoma progression.

Abstract
Notch1 signaling plays a key role in normal developmental processes and in cancer. The association between Notch activation and development of cancer has been well documented. Notch activation and outcome of the disease depend upon the crosstalk with other regulatory pathways including Nuclear Factor kappa B (NFκB) pathway. In this study, we have investigated the interaction of Notch intracellular domain (NICD) with NFκBp65 in colorectal cancer which resulted in the upregulation of Bcl-xL resulting in the inhibition of apoptosis. Mesenchymal marker Slug expression and down regulation of E-cadherin, an epithelial phenotypic marker were demonstrated in colon cancer tissues. The study was also illustrated by using the gamma secretase inhibitor, N-[N-(3,5-difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester (DAPT) in HT29 cells. Immunohistochemistry (NICD, NFκBp65, and Slug) and double immunofluorescence analysis (NICD, NFκBp65) revealed that NICD and NFκBp65 were highly expressed in HT29 cells and in tumor tissue compared to normal tissue. Slug and Bcl-xL protein expressions were significantly reduced in DAPT treated HT 29 cells. Immunoprecipitation and dual staining emphasized the strong interaction of NICD with NFκBp65 in adenocarcinoma than in normal tissue. It appeared that Notch1 and NFκB could independently contribute to tumor progression. However, their interaction and synergism might be the determinants that would affect the outcome of the disease and therapeutic interventions.

Abstract
Tianeptine sodium salt (TSS) is a selective facilitator of serotonin, but there are no reports regarding anti-invasive effects of TSS. Therefore, we investigated the effect of TSS on the expression of matrix metalloproteinase-9 (MMP-9) and invasion in three different human carcinoma cell lines. Our findings showed that MMP-9 activity was significantly increased in response to tumor necrosis factor-α (TNF-α), and that TSS reduced TNF-α-induced MMP-9 activity in a dose-dependent manner. TSS also downregulated both MMP-9 expression and TNF-α-induced MMP-9 promoter activity. Using a matrigel invasion assay, we showed that TSS significantly attenuated invasive rates in TNF-α-stimulated LNCaP prostate carcinoma cells. Furthermore, TSS suppressed TNF-α-induced NF-κB activity, which is a potential transcriptional factor for regulating many invasive genes, including MMP-9, by suppressing IκB degradation and nuclear translocation of NF-κB subunits in LNCaP prostate carcinoma cells. TSS also downregulated TNF-α-induced phosphorylation of phosphatidyl-inositol 3 kinase (PI3K) and Akt, and a selective PI3K/Akt inhibitor, LY294002, diminished TNF-α-induced NF-κB activation followed by levels of MMP-9, suggesting that TSS also reduces MMP-9 expression by inhibiting the PI3K/Akt-mediated NF-κB pathway. These results indicate that TSS is a potential anti-invasive agent by suppression of TNF-α-induced MMP-9 expression via inhibition of PI3K/Akt-mediated NF-κB activity.

Abstract
Abstract
Rubus coreanus Miquel (RCM) is used to promote prostate health and has been shown to have anti-oxidant and anti-carcinogenic activities. However, the effects and mechanisms of RCM on prostate cancer metastasis remain unclear. PC-3 and DU 145 cells were treated with ethanol or water extract of unripe or ripe RCM and examined for cell invasion, migration, and matrix metalloproteinases (MMPs) activity and expression. Phosphoinositide 3-kinase (PI3K) and Akt activities were examined. Unripe RCM extracts exerted significant inhibitory effects on cell migration, invasion, and MMPs activities. A significant reduction in MMPs activities by unripe RCM ethanol extract treatment (UE) was associated with reduction of MMPs expression and induction of tissue inhibitors of metalloproteinases (TIMPs) expression. Furthermore, PI3K/Akt activity was diminished by UE treatment. In this study, we demonstrated that UE decreased metastatic potential of prostate cancer cells by reducing MMPs expression through the suppression of PI3K/Akt phosphorylation, thereby decreasing MMP activity and enhancing TIMPs expression.

Abstract
The laver (Porphyra tenera), red seaweed, has been reported to have anticancer activity, but little is known about its molecular mechanisms of action. The objective of this study was to determine the effects of laver extract on cancer cell proliferation, invasion, and metastasis in SK-Hep1 cells using migration and invasion assays. We also investigated the relationship of MMP-2/-9 and TIMP-1/-2 expression at both the protein and gene level in SK-Hep1 human hepatoma carcinoma cells after laver extract treatment. Laver extract inhibited cancer cell growth in a dose-dependent manner. In an invasion assay conducted in Transwell chambers, laver extract showed 19.6 and 27.2% inhibition of cancer cell at 200 and 400 μg/mL, respectively, compared to the control. The mRNA levels of both MMP-2 and MMP-9 were down-regulated by laver extract treatment in a dose-dependent manner. Laver extract, at 400 μg/mL, was inhibited by MMP-2 and MMP-9 expressions by 70.1 and 77.0%, respectively. An inverse relationship in the mRNA contents of MMP-2/-9 and TIMP-1/-2 expressions in SK-Hep1 cells was found by laver extract treatment. Our results demonstrate antimetastatic properties of laver extract in inhibiting the adhesion, invasion, and migration of SK-Hep1 human hepatoma cancer cells.

Abstract
OBJECTIVE To determine the effect of hyaluronic acid (HA) on proteolytic enzymes and bone remodeling mediators induced by interleukin 1β (IL-1β) and related to cartilage catabolism in murine osteoblasts. METHODS Osteoblasts were obtained from Swiss mice and cultured for 3 weeks. HA-treated osteoblasts were incubated with 100 μg/ml HA during the last week of culture, then stimulated with IL-1β (10 ng/ml) for 24 h. The expression of matrix metalloproteinases 3 and 13 (MMP-3 and MMP-13), ADAMTS-4 and ADAMTS-5, tissue inhibitor of metalloproteinases (TIMP), osteoprotegerin, and receptor activator of nuclear factor-κB ligand (RANKL) was determined by real-time polymerase chain reaction. MMP-3 and MMP-13 release was assessed by Western blot analysis. RESULTS IL-1β increased the mRNA levels of MMP-3 and MMP-13 and ADAMTS-4 and ADAMTS-5 and release of MMP-3 and MMP-13. Seven days of HA treatment significantly prevented the IL-1β-increased mRNA levels of MMP-3 (-61%, p < 0.01), MMP-13 (-56%, p < 0.01), ADAMTS-4 (-58%, p < 0.05), ADAMTS-5 (-52%, p < 0.01), and RANKL (-49%, p < 0.05), but not TIMP. As well, IL-1β-induced production of MMP-3 and MMP-13 was inhibited, by 27% (p < 0.01) and 40% (p < 0.01), respectively. CONCLUSION In an inflammatory context in murine osteoblasts, HA can inhibit the expression of MMP and ADAMTS. Because HA can counteract the production of these mediators in chondrocytes, its beneficial effect in osteoarthritis may be due to its action on cartilage and subchondral bone.

Abstract
Little is known about the molecular mechanism through which 18β-glycyrrhetinic acid (GA) inhibits metastasis and invasion of cancer cells. Therefore, this study aimed to investigate the effects of GA on the expression of matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) in various types of cancer cells. We found that treatment with GA reduces tumor necrosis factor-α (TNF-α)-induced Matrigel invasion with few cytotoxic effects. Our findings also showed that MMP-9 and VEGF expression increases in response to TNF-α; however, GA reverses their expression. In addition, GA inhibited inhibitory factor kappa B degradation, sustained nuclear factor-kappa B (NF-κB) subunits, p65 and p50, in the cytosol compartments, and consequently suppressed the TNF-α-induced DNA-binding activity and luciferase activity of NF-κB. Specific NF-κB inhibitors, pyrrolidine dithiocarbamate, MG132, and PS-1145, also attenuated TNF-α-mediated MMP-9 and VEGF expression as well as activity by suppressing their regulatory genes. Furthermore, phosphorylation of TNF-α-induced phosphatidyl-inositol 3 kinase (PI3K)/Akt was significantly downregulated in the presence of GA accompanying with the inhibition of NF-κB activity, and as presumed, the specific PI3K/Akt inhibitor LY294002 significantly decreased MMP-9 and VEGF expression as well as activity. These results suggest that GA operates as a potential anti-invasive agent by downregulating MMP-9 and VEGF via inhibition of PI3K/Akt-dependent NF-κB activity. Taken together, GA might be an effective anti-invasive agent by suppressing PI3K/Akt-mediated NF-κB activity.

Arch Med Res 2014; 45:203-9. [PMID: 24606818 DOI: 10.1016/j.arcmed.2014.01.008] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2013] [Accepted: 01/23/2014] [Indexed: 11/17/2022]
Abstract
BACKGROUND AND AIMS Diabetes is a risk factor for exacerbated outcome after acute myocardial infarction (AMI) and doubles the risk of mortality after MI. Increased levels of MMP-2 and MMP-9 in diabetes cause vascular remodelling, which leads to cardiovascular complications of diabetes. We hypothesized that inhibition of MMP-2 and MMP-9 can reduce worsening of myocardial ischemia in diabetic patients. Further, we hypothesized that minocycline induced MMP-2 and MMP-9 inhibition will be potentiated by aspirin and the combination of both drugs will prevent worsening of MI in diabetic patients. In the present study, efficacy of combination of minocycline and aspirin to attenuate exacerbation of myocardial ischemia/reperfusion (I/R) injury in diabetic rats was evaluated. METHODS Diabetes was induced in male Wistar rats by streptozotocin (55 mg/kg i.p.). Three weeks after diabetes induction, rats were treated with minocycline (50 mg/kg, p.o.), aspirin (50 mg/kg, p.o.), or minocycline (50 mg/kg, p.o.) plus aspirin (50 mg/kg, p.o.) for a period of 3 weeks. At the end of week 6, I/R injury was induced by ligating the left anterior descending coronary artery for 30 min followed by 2 h reperfusion. RESULTS Percentage infarct volume, arrhythmias, mortality, collagen level and MMP-2 and MMP-9 level were significantly increased in vehicle-treated diabetic group when compared with normoglycemic rats. Treatment with a combination of minocycline and aspirin decreased percentage infarct volume, arrhythmias, mortality and collagen level when compared with vehicle-treated diabetic controls and showed reduced levels of MMP-2 and MMP-9. CONCLUSIONS Results of the present study suggest that the combination of minocycline and aspirin prevent worsening of AMI in diabetic rats.
