Abstract
Vascular endothelial cells (ECs) are monolayers of cells arranged in the inner walls of blood vessels. Under normal physiological conditions, ECs play an essential role in angiogenesis, homeostasis and immune response. Emerging evidence suggests that abnormalities in EC metabolism, especially aerobic glycolysis, are associated with the initiation and progression of various diseases, including multiple cancers. In this review, we discuss the differences in aerobic glycolysis of vascular ECs under normal and pathological conditions, focusing on the recent research progress of aerobic glycolysis in tumor vascular ECs and potential strategies for cancer therapy.

Modulation of hypoxia-inducible factor-1 signaling pathways in cancer angiogenesis, invasion, and metastasis by natural compounds: a comprehensive and critical review. Cancer Metastasis Rev 2024; 43:501-574. [PMID: 37792223 DOI: 10.1007/s10555-023-10136-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 09/07/2023] [Indexed: 10/05/2023]
Abstract
Tumor cells employ multiple signaling mediators to escape the hypoxic condition and trigger angiogenesis and metastasis. As a critical orchestrate of tumorigenic conditions, hypoxia-inducible factor-1 (HIF-1) is responsible for stimulating several target genes and dysregulated pathways in tumor invasion and migration. Therefore, targeting HIF-1 pathway and cross-talked mediators seems to be a novel strategy in cancer prevention and treatment. In recent decades, tremendous efforts have been made to develop multi-targeted therapies to modulate several dysregulated pathways in cancer angiogenesis, invasion, and metastasis. In this line, natural compounds have shown a bright future in combating angiogenic and metastatic conditions. Among the natural secondary metabolites, we have evaluated the critical potential of phenolic compounds, terpenes/terpenoids, alkaloids, sulfur compounds, marine- and microbe-derived agents in the attenuation of HIF-1, and interconnected pathways in fighting tumor-associated angiogenesis and invasion. This is the first comprehensive review on natural constituents as potential regulators of HIF-1 and interconnected pathways against cancer angiogenesis and metastasis. This review aims to reshape the previous strategies in cancer prevention and treatment.

Abstract
BACKGROUND Matrix metalloproteinases (MMP) are important proteases that degrade the extracellular matrix (ECM) and thus essentially mediate tumor vascularization, metastasis, and invasion. However, their potential roles in uterine corpus endometrial carcinoma (UCEC) are not fully understood. PATIENTS AND METHODS The expression, prognostic value, and correlation of UCEC patients with MMP were investigated using data from The Cancer Genome Atlas (TCGA) and other databases. Furthermore, differentially expressed genes (DEGs) were identified and their biological functions and correlations with infiltrating immune cells were analyzed. RESULTS A total of 22 MMPs were found to be abnormally expressed in UCEC tumor tissues, and high expression of MMP11 and MMP17 were associated with a better UCEC prognosis. MMP11 and MMP17 were observed to be significantly enriched in tumor tissue ECM and were associated with pathways involving degradation, glycolytic metabolism, and PI3K-Akt signaling. Infiltration of natural killer (NK), mast, and NK CD56bright cells was enhanced in tumor tissues with high MMP11 and MMP17 expression. CONCLUSION MMP11 and MMP17 may affect UCEC prognosis by influencing immune cell infiltration and may be potential UCEC biomarkers.

Ali M, Stone D, Laknaur A, Yang Q, Al-Hendy A. EZH2 activates Wnt/β-catenin signaling in human uterine fibroids, which is inhibited by the natural compound methyl jasmonate. F&S SCIENCE 2023; 4:239-256. [PMID: 37182601 PMCID: PMC10527015 DOI: 10.1016/j.xfss.2023.05.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 05/05/2023] [Accepted: 05/09/2023] [Indexed: 05/16/2023]
Abstract
OBJECTIVE To investigate the link between EZH2 and Wnt/β-catenin signaling and its role in uterine fibroids (UFs) pathogenesis and explore the potential effect of natural compound methyl jasmonate (MJ) against UFs. DESIGN EZH2 overexpression or inhibition was achieved in human uterine leiomyoma (HuLM) cells using EZH2-expressing adenovirus or chemical EZH2 inhibitor (DZNep), respectively. The HuLM and normal uterine smooth muscle cells were treated with 0.1-3 mM of MJ, and several experiments were employed. SETTING Laboratory study. PATIENTS(S) None. INTERVENTION(S) Methyl jasmonate. MAIN OUTCOME MEASURE(S) Protein expression of EZH2, β-catenin, and proliferating cell nuclear antigen (PCNA) was measured by Western blot as well as gene expression alterations of Wnt ligands (Wnt5A, Wnt5b, and Wnt9A), WISP1, CTNNB1, and its responsive gene PITX2 using quantitative real-time polymerase chain reaction. The protein and ribonucleic acid (RNA) levels of several markers were measured in MJ-treated or untreated HuLM cells, including EZH2 and β-catenin, extracellular matrix markers collagen type 1 (COL1A1) and fibronectin (FN), proliferation markers cyclin D1 (CCND1) and PCNA, tumor suppressor marker p21, and apoptotic markers (BAX, cytochrome c, and cleaved caspase 3). RESULT(S) EZH2 overexpression significantly increased the gene expression of several Wnt ligands (PITX2, WISP1, WNT5A, WNT5B, and WNT9A), which increased nuclear translocation of β-catenin and PCNA and eventually HuLM cell proliferation. EZH2 inhibition blocked Wnt/β-catenin signaling activation where the aforementioned genes significantly decreased as well as PCNA, cyclin D1, and PITX2 protein expression compared with those in untreated HuLM. Methyl jasmonate showed a potent antiproliferative effect on HuLM cells in a dose- and time-dependent manner. Interestingly, the dose range (0.1-0.5 mM) showed a selective growth inhibitory effect on HuLM cells, not on normal uterine smooth muscle cells. Methyl jasmonate treatment at 0.5 mM for 24 hours significantly decreased both protein and RNA levels of EZH2, β-catenin, COL1A1, FN, CCND1, PCNA, WISP1, and PITX2 but increased the protein levels of p21, BAX, cytochrome, c and cleaved caspase 3 compared with untreated HuLM. Methyl jasmonate-treated cells exhibited down-regulation in the RNA expression of 36 genes, including CTNNB1, CCND1, Wnt5A, Wnt5B, and Wnt9A, and up-regulation in the expression of 34 genes, including Wnt antagonist genes WIF1, PRICKlE1, and DKK1 compared with control, confirming the quantitative real-time polymerase chain reaction results. CONCLUSION(S) Our studies provide a novel link between EZH2 and the Wnt/β-catenin signaling pathway in UFs. Targeting EZH2 with MJ interferes with the activation of wnt/β-catenin signaling in our model. Methyl jasmonate may offer a promising therapeutic option as a nonhormonal and cost-effective treatment against UFs with favorable clinical utility, pending proven safe and efficient in human clinical trials.

Abstract
BACKGROUND Uveal melanoma (UVM) is the leading cause of eye-related mortality worldwide. This study aimed to explore the expression and prognostic value of matrix metalloproteinases (MMPs) in UVM. METHODS Gene expression levels were obtained from the Gene Expression Omnibus (GEO) and Oncomine databases. Functional and pathway enrichment analyses were performed using the Metascape database. GeneMANIA was then applied to construct a protein-protein interaction network and identify the hub genes. Moreover, overall survival (OS) and disease-free survival (DFS) analysis for the hub genes was performed using the UALCAN and Gene Expression Profiling Interactive Analysis (GEPIA) online tool. Furthermore, TRRUST was used to predict the targets of the MMPs. RESULTS Our results revealed that the transcriptional levels of MMP1, MMP9, MMP10, MMP11, MMP13, MMP14, and MMP17 were upregulated in UVM tissues compared to normal tissues. A protein-protein interaction (PPI) network was constructed and the top 50 hub genes were identified. The functions of MMPs and their neighboring proteins are mainly associated with ECM-receptor interaction, proteoglycans in cancer, the IL-17 signaling pathway, and microRNAs in cancer. Among the MMPs, MMP1/2/9/11/14/15/16/17/24 played significant roles in the progression of UVM from stage 3 to stage 4. We also found that the expression of MMP1, MMP2, MMP9, and MMP16 positively correlated with OS and DFS in patients with UVM. Additionally, 18 transcription factors associated with nine MMPs were identified. CONCLUSIONS The results of this study may provide potential biomarkers and targets for UVM. However, further studies are required to confirm these results.

Abstract
Purpose Recent studies have suggested that molecular targets for the anti-angiogenic therapy might constitute a basis for additional therapy in gastric cancer treatment. A vast number of molecules, receptors, pathways, specific interactions, and thus strategies that target gastric cancer angiogenesis specifically have been reported in numerous research articles and clinical trials. Methods We conducted a systematic literature review of molecularly targeted treatment strategies in gastric cancer on the following databases—PubMed, Google Scholar, and Scopus—on September 20, 2020. Multiple articles and evaluations were searched for studies reporting newly found and promising molecular anti-angiogenic therapy pathways. Eventually, 39 articles regarding the anti-angiogenic therapy in gastric cancer were included in the final analysis. Results As a consequence of the release of the pro-angiogenic molecules from the tumour cells, gastric cancer presents high angiogenic capability. Therefore, potential schemes for future treatment strategies include the decrease of the process ligands as well as the expression of their receptors. Moreover, the increase in the angiogenic inhibitor levels and direct aim for the inner walls of the endothelial cells appear as a promising therapeutic strategy. Beyond that, angiogenesis process inhibition seems to indirectly exaggerate the effects of chemotherapy in the considered patients. Conclusions The anti-angiogenic treatment in gastric cancer patients evaluates its significance especially in the early stages of the malignancy. The studies conducted so far show that most of the meaningful angiogenic factors and receptors with the potential molecular pathways should be further evaluated since they could potentially play a substantial role in future therapies.

Abstract
Angiogenesis, a process of new blood vessel formation from the pre-existing vascular bed, is a critical event in various physiological and pathological settings. Over the last few years, the role of endothelial cell (EC) metabolism in angiogenesis has received considerable attention. Accumulating studies suggest that ECs rely on aerobic glycolysis, rather than the oxidative phosphorylation pathway, to produce ATP during angiogenesis. To date, numerous critical regulators of glucose metabolism, fatty acid oxidation, and glutamine metabolism have been identified to modulate the EC angiogenic switch and pathological angiogenesis. The unique glycolytic feature of ECs is critical for cell proliferation, migration, and responses to environmental changes. In this review, we provide an overview of recent EC glucose metabolism studies, particularly glycolysis, in quiescent and angiogenic ECs. We also summarize and discuss potential therapeutic strategies that take advantage of EC metabolism. The elucidation of metabolic regulation and the precise underlying mechanisms could facilitate drug development targeting EC metabolism to treat angiogenesis-related diseases.

Abstract
Medicinal plants offer enormous possibilities in the quest of novel bioactive formulation for cancer therapy. Here, we studied the anticancer efficacy of the extract of edible tuber Amorphophallus paeoniifolius (Dennst.) (APTE) against estrogen positive MCF-7 and triple negative MDA-MB-231 breast cancer cell lines. APTE showed significant cytotoxic activity in both MCF-7 and MDA-MB-231 cells in a dose and time-dependent manner. The effect of APTE on metastatic parameters e.g., migration, adhesion, and invasion in MCF-7 and MDA-MB-231 cells were studied using wound healing, collagen adhesion, and transwell matrigel invasion assays, respectively. APTE significantly reduced migration in both the cell lines, however, its effect on the inhibition of adhesion and invasion was higher in MDA-MB-231 cells. Annexin V-Cy3 staining suggested that APTE induced apoptosis in these cells which was further validated by attenuation of antiapoptotic Bcl-2 and induction of pro-apoptotic Bax, Caspase-7 expression and cleavage of PARP. High resolution-liquid chromatography mass spectroscopy analysis with bioactive ethyl acetate and butanol fractions of APTE detected several compounds with anticancer activities. Overall, the study described the mechanism of anticancer activity of a common edible tuber A. paeoniifolius and contributes to growing list of naturally occurring chemo-preventive strategies.

Abstract
Recent studies suggest that long noncoding RNAs (lncRNAs) play essential roles in tumor progression. However, the functional roles and underlying mechanisms of lncRNAs in neuroblastoma (NB), the most common malignant solid tumor in pediatric population, still remain elusive. Herein, through integrating analysis of a public RNA sequencing dataset, neuroblastoma highly expressed 1 (NHEG1) was identified as a risk-associated lncRNA, contributing to an unfavorable outcome of NB. Depletion of NHEG1 led to facilitated differentiation and decreased growth and aggressiveness of NB cells. Mechanistically, NHEG1 bound to and stabilized DEAD-box helicase 5 (DDX5) protein through repressing proteasome-mediated degradation, resulting in β-catenin transactivation that altered target gene expression associated with NB progression. We further determined a lymphoid enhancer binding factor 1 (LEF1)/transcription factor 7-like 2 (TCF7L2)/NHEG1/DDX5/β-catenin axis with a positive feedback loop and demonstrated that NHEG1 harbored oncogenic properties via its interplay with DDX5. Administration of small interfering RNAs against NHEG1 or DDX5 reduced tumor growth and prolonged survival of nude mice bearing xenografts. High NHEG1 or DDX5 expression was associated with poor survival of NB patients. These results indicate that lncRNA NHEG1 exhibits oncogenic activity that affects NB progression via stabilizing the DDX5 protein, which might serve as a potential therapeutic target for NB.

[PMID: 31956360 PMCID: PMC6959085 DOI: 10.7150/jca.36469] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Accepted: 11/20/2019] [Indexed: 12/24/2022] Open
Abstract
Background: The Matrix metalloproteinase-14 (MMP-14) expression has been shown to be overexpressed in different cancers. However, there is no comprehensive quantitative evaluation of the MMP-14 prognostic value in digestive system carcinoma (DSC). The aim of this study is to explore the correlation between the MMP-14 expression and DSC prognosis. Methods: We conducted a meta-analysis to estimate the association strength between MMP-14 expression and prognosis. GEPIA and Kaplan Meier plotters were used to assess overall survival (OS), disease-free survival (DFS)/progression-free survival (PFS) in DSC patients and the differential expression of MMP-14 in DSC tissues and adjacent tissues. Results: A total of 20 studies including 2,519 patients with OS and 438 patients with DFS/PFS data were analyzed in evidence synthesis. Overall, the combined hazard ratio (HR) with 95% confidence interval (95% CI) was 1.98 (95%Cl: 1.77-2.22, P<0.001) for OS and 3.61 (95%Cl: 2.39-5.43, P<0.001) for DFS/PFS. For subgroup analyses, significant correlations were revealed between increased MMP-14 expression and poor OS in patients with gastric cancer (HR=2.21, 95%CI: 1.76-2.77, P<0.001), esophageal carcinoma (HR=2.01, 95%CI: 1.58-2.57, P<0.001), oral cancer (HR = 1.69, 95% CI: 1.30-2.20, P < 0.001) (HR=2.14, 95%CI 1.35-2.19, P<0.001) and hepatocarcinoma. In database verification analyses, the MMP-14 expression levels in normal tissues were significantly higher than that in DSC tissues, and significant associations were observed between high MMP-14 expression levels and poor prognosis. Conclusions: The high expression levels of MMP-14 might predict poor prognosis in DSC. Larger prospective clinical cohort studies are required to validate the prognostic role.

Abstract
Melanoma is the most aggressive form of skin cancer, with metastatic melanoma being refractory to currently available conventional therapies. In this study, we evaluated the inhibitory effect of coronatine (COR) on the proliferation of metastatic melanoma cells. COR inhibited the proliferation of melanoma cells but negligibly affected the proliferation of normal melanocytes. Comparative metabolic and lipidomic profiling using gas chromatography-mass spectrometry and direct infusion-mass spectrometry was performed to investigate COR-induced metabolic changes. These analyses identified 33 metabolites and 82 lipids. Of these, the levels of lactic acid and glutamic acid, which are involved in energy metabolism, significantly decreased in COR-treated melanoma cells. Lipidomic profiling indicated that ceramide levels increased in COR-treated melanoma cells, suggesting that ceramides could function as a suppressor of cancer cell proliferation. In contrast, the levels of phosphatidylinositol (PI) species, including PI 16:0/18:0, 16:0/18:1, 18:0/18:0, and 18:0/18:1, which were found to be potential biomarkers of melanoma metastasis in our previous study, were lower in the COR-treated cells than in control cells. The findings of metabolomic and lipidomic profiling performed in the present study provide new insights on the anticancer mechanisms of COR and can be used to apply COR in cancer treatment.

Abstract
The present study aimed to explore the possible effects of membrane‑type 1 matrix metalloproteinase (MT1‑MMP) on gastric carcinoma cells proliferation and invasion. Immunohistochemistry analysis was conducted to measure MT1‑MMP expression level in 15 patients with gastric carcinoma. Subsequently, recombinant short hairpin RNA (shRNA) vectors targeting MT1‑MMP were constructed to silence the expression of MT1‑MMP in gastric carcinoma cells. Then, the inhibitive efficiency was verified via reverse transcription quantitative polymerase chain reaction (RT‑qPCR) and western blot analysis. The effects of MT1‑MMP silencing on cell proliferation and invasion were detected through Cell Counting Kit‑8 test and Transwell assays. The expression levels of vimentin and epithelial cadherin (E‑cadherin) were detected by RT‑qPCR. The immunohistochemistry analysis results revealed that MT1‑MMP expression in gastric carcinoma tissues was markedly overexpressed compared with non‑cancerous adjacent tissues. The MT1‑MMP expression level in cancer‑derived cell line AGS cells was also significantly increased compared with that in non‑cancer‑derived GES‑1 cells. In addition, the MT1‑MMP expression level in AGS cells was significantly decreased via shRNA transfection. Cell proliferation and invasion were markedly inhibited following knockdown of MT1‑MMP level in AGS cells. These inhibitory effects were associated with the decreased expression of vimentin and increased expression of E‑cadherin. MT1‑MMP was overexpressed in gastric carcinoma cells, and silencing of MT1‑MMP inhibited the proliferation and invasion of cells via regulating the expression of vimentin and E‑cadherin.

Abstract
Prolyl 4-hydroxylase alpha subunit is the enzymic active site of prolyl 4-hydroxylase, which is a critical enzyme to maintain the stability of newly synthesized collagens. The expression profile and functional role of P4HA3 in gastric cancer have not been explored. In the Cancer Genome Atlas-Stomach Cancer, P4HA3 RNA is significantly upregulated in gastric cancer than in normal stomach tissues. In the Human Protein Atlas, Prolyl 4-hydroxylase alpha subunit is not detectable by immunohistochemistry staining in normal stomach tissues, but it has weak staining in 7 of 12 gastric cancer tissues. Further study showed that SNAI2 (encoding Slug) is highly coexpressed with P4HA3 (Pearson r = 0.70) in Cancer Genome Atlas-Stomach Cancer. In vitro cell assay showed that Slug could efficiently bind to the P4HA3 promoter and increase its transcription. P4HA3 exon array data in Cancer Genome Atlas-Stomach Cancer revealed that 2 exons are significantly upregulated in M1 (N = 27) cases than in M0 (N = 367) cases. In MKN-45 and AGS cells, P4HA3 upregulation could enhance cell motility and invasiveness. In Cancer Genome Atlas-Stomach Cancer, high P4HA3 exon expression is associated with significantly worse 5-year and 10-year overall survival (P = .007 and .009, respectively). Data mining in Kaplan-Meier plotter also showed that high P4HA3 expression is related to unfavorable overall survival (hazard ratio: 1.54, 95% confidence interval: 1.23-1.93, P < .001) and first progression-free survival (hazard ratio: 1.64, 95% confidence interval: 1.29-2.1, P < .001). Based on findings above, we infer that P4HA3 is epigenetically activated by Slug, and its deregulation is associated with enhanced metastasis and poor survival of gastric cancer.

Abstract
Matrix metalloproteinases (MMPs), endopeptidases with diverse biochemical functions, can promote cancer cell invasion and metastasis by degrading the extracellular matrix. A high matrix metalloproteinase-14 (MMP-14) expression in gastric cancer tissue has been associated with metastasis and poor prognosis. To further understand this association, we investigated serum MMP-14 as a biomarker in gastric cancer patients. The patient cohort consisted of 240 gastric adenocarcinoma patients who underwent surgery at Helsinki University Hospital, Finland, between 2000 and 2009. We determined the soluble MMP-14 serum levels using an enzyme-linked immunosorbent assay. We then calculated the associations between serum levels and clinicopathologic variables using the Mann-Whitney U-test or the Kruskal-Wallis test. We constructed survival curves using the Kaplan-Meier method and calculating the hazard ratios using the Cox proportional hazard model. We revealed a positive association between a high serum MMP-14 level and stages III–IV (p = 0.029), and between a high serum MMP-14 and distant metastasis (p = 0.022). Patients with a low serum MMP-14 had a 5-year disease-specific survival of 49.2% (95% confidence interval [CI] 45.5–52.9), whereas patients with a high serum MMP-14 had a 5-year survival of 22.1% (95% CI 15.2–29.0; p = 0.001). High serum MMP-14 was a statistically significant prognostic factor among patients with an intestinal type of cancer (hazard ratio [HR] 3.54; 95% CI 1.51–8.33; p = 0.004), but not among patients with a diffuse type. The serum MMP-14 level remained an independent prognostic factor in our multivariate survival analysis (HR 1.55; 95% CI 1.02–2.35; p = 0.040). This study indicates for the first time that high serum soluble MMP-14 levels in gastric cancer serves as a marker for a poor prognosis, possibly indicating the presence of distant metastases.

Abstract
Purpose In our previous study, we found that AKR1C3 was a radioresistance gene in KY170R cells. Downregulating the expression of AKR1C3 could enhance the radiosensitivity of esophageal carcinoma cells. In this study, we investigated whether methyl jasmonate (MeJ), an inhibitor of Aldo-keto reductase family1 member C3 (AKR1C3), could overcome radiation resistance in AKR1C3 highly expressed cells. Patients and methods We used clone formation assays to detect radiosensitivity effects. Flow cytometry assays were used to detect reactive oxygen species (ROS) accumulation and apoptosis. Enzyme linked immunosorbent assays (ELISAs) were used to detect the concentrations of prostaglandin F2 (PGF2) and prostaglandin D2 (PGD2) in the cells after incubation with MeJ. Western blotting was used to detect AKR1C3 and peroxisome proliferator-activated receptor gamma (PPARγ) expression. Results We found that AKR1C3 was highly expressed in radioresistant esophageal carcinoma cells. MeJ inhibited the expression of AKR1C3 and enhanced the radiation sensitivity of esophageal carcinoma cells expressing high levels of AKR1C3 (P<0.05). MeJ could inhibit the 11-ketoprostaglandin reductase activity of AKR1C3 in a dose-dependent manner in KY170R cells. Incubation of KY170R cells with 200 µmol/L of MeJ for 24 h reduced the expression of PGF2 by roughly 30% (P<0.05). The PPAR pathway inhibitor GW9662 prevented the radiation sensitivity enhancement imparted by MeJ. After adding GW9662, there were no significant differences between the radiation sensitivities of MeJ-treated and -untreated KY170R cells (P>0.05). The radiation sensitivity effect of MeJ also depended upon the generation of ROS in KY170R cells; 48 h after irradiation, ROS levels in the MeJ group was twofold higher than in the untreated KY170R cells (P<0.05). The ROS scavenger, N-acetyl cysteine, could reverse the radiosensitivity effects of MeJ (P>0.05). Conclusion Our results indicate that MeJ can increase the radiation sensitivity of AKR1C3-overexpressing KY170R cells by inhibiting the 11-ketoprostaglandin reductase activity of AKR1C3 and increasing cellular ROS levels.

Abstract
Methyl jasmonate potentially induces the differentiation of human myeloid leukemia cells and inhibits their proliferation; it may induce the differentiation and apoptosis of human lymphocytic leukemia cells, but does not exert a damaging effect on normal lymphocytes. In the present study, the anticancer effect of methyl jasmonate on human colorectal cancer cells was investigated. Cell viability and apoptosis was assessed using a Cell Counting kit-8 assay and flow cytometry, respectively. Methyl jasmonate suppressed cell viability and induced apoptosis in human colorectal cancer cells. Additionally, methyl jasmonate increased the activation of caspase-3, inhibited the expression levels of enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) and the Wnt/β-catenin pathway in human colorectal cancer. Downregulation of EZH2 expression enhanced the anticancer effect of methyl jasmonate on human colorectal cancer cells through suppression of the Wnt/β-catenin pathway. Thus, EZH2 downregulation promotes the anticancer effect of methyl jasmonate by inducing apoptosis in human colorectal cancer cells through the Wnt/β-catenin pathway.

Abstract
Emerging studies have indicated the essential functions of long noncoding RNAs (lncRNAs) during cancer progression. However, whether lncRNAs contribute to the upregulation of v-ets erythroblastosis virus E26 oncogene homolog 1 (Ets-1), an established oncogenic protein facilitating tumor invasion and metastasis, in gastric cancer remains elusive. Herein, we identified Ets-1 promoter-associated noncoding RNA (pancEts-1) as a novel lncRNA associated with the gastric cancer progression via mining of publicly available datasets and rapid amplification of cDNA ends. RNA pull-down, RNA immunoprecipitation, in vitro binding, and RNA electrophoretic mobility shift assays indicated the binding of pancEts-1 to non-POU domain containing octamer binding (NONO) protein. Mechanistically, pancEts-1 facilitated the physical interaction between NONO and Ets related gene (ERG), resulting in increased ERG transactivation and transcription of Ets-1 associated with gastric cancer progression. In addition, pancEts-1 facilitated the growth and aggressiveness of gastric cancer cells via interacting with NONO. In gastric cancer tissues, pancEts-1, NONO, and ERG were upregulated and significantly correlated with Ets-1 levels. High levels of pancEts-1, NONO, ERG, or Ets-1 were respectively associated with poor survival of gastric cancer patients, whereas simultaneous expression of all of them (HR = 3.012, P = 0.105) was not an independent prognostic factor for predicting clinical outcome. Overall, these results demonstrate that lncRNA pancEts-1 exhibits oncogenic properties that drive the progression of gastric cancer via regulating the NONO/ERG/Ets-1 axis.

Abstract
Methyl jasmonate has recently been found to have anti-cancer activity. Methyl jasmonate detached hexokinase 2 from a voltage dependent anion channel causing a reduction in mitochondrial transmembrane potential that led to the release of cytochrome C and apoptosis inducing factor resulting in intrinsic apoptosis. Blocked adenosine triphosphate synthesis caused by mitochondrial injury hampered oxidative phosphorylation and led to cell necrosis. The results were applied to the in vivo treatment of nude mice with a satisfactory effect. Collectively, our results suggest that methyl jasmonate may be an adjuvant therapy for liver tumors due to its mechanism in cancer cells compared to that in normal cells: The major function is to inhibit glycolysis instead of changing aerobic metabolism.

HPSE enhancer RNA promotes cancer progression through driving chromatin looping and regulating hnRNPU/p300/EGR1/HPSE axis. Oncogene 2018; 37:2728-2745. [PMID: 29511351 DOI: 10.1038/s41388-018-0128-0] [Citation(s) in RCA: 69] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Revised: 12/08/2017] [Accepted: 12/19/2017] [Indexed: 12/15/2022]
Abstract
Recent studies reveal the emerging functions of enhancer RNAs (eRNAs) in gene expression. However, the roles of eRNAs in regulating the expression of heparanase (HPSE), an established endo-β-D-glucuronidase essential for cancer invasion and metastasis, still remain elusive. Herein, through comprehensive analysis of publically available FANTOM5 expression atlas and chromatin interaction dataset, we identified a super enhancer and its derived eRNA facilitating the HPSE expression (HPSE eRNA) in cancers. Gain-of-function and loss-of-function experiments indicated that HPSE eRNA facilitated the in vitro and in vivo tumorigenesis and aggressiveness of cancer cells. Mechanistically, as a p300-regulated nuclear noncoding RNA, HPSE eRNA bond to heterogeneous nuclear ribonucleoprotein U (hnRNPU) to facilitate its interaction with p300 and their enrichment on super enhancer, resulting in chromatin looping between super enhancer and HPSE promoter, p300-mediated transactivation of transcription factor early growth response 1 (EGR1), and subsequent elevation of HPSE expression. In addition, rescue studies in HPSE overexpressing or silencing cancer cells indicated that HPSE eRNA exerted oncogenic properties via driving HPSE expression. In clinical cancer tissues, HPSE eRNA was highly expressed and positively correlated with HPSE levels, and served as an independent prognostic factor for poor outcome of cancer patients. Therefore, these findings indicate that as a novel noncoding RNA, HPSE eRNA promotes cancer progression through driving chromatin looping and regulating hnRNPU/p300/EGR1/HPSE axis.

miRNA-337-3p inhibits gastric cancer progression through repressing myeloid zinc finger 1-facilitated expression of matrix metalloproteinase 14. Oncotarget 2018; 7:40314-40328. [PMID: 27259238 PMCID: PMC5130010 DOI: 10.18632/oncotarget.9739] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2016] [Accepted: 05/13/2016] [Indexed: 11/25/2022] Open
Abstract
Matrix metalloproteinase 14 (MMP-14), a membrane-anchored MMP that promotes the tumorigenesis and aggressiveness, is highly expressed in gastric cancer. However, the transcriptional regulators of MMP-14 expression in gastric cancer still remain largely unknown. In this study, through mining computational algorithm programs and chromatin immunoprecipitation datasets, we identified adjacent binding sites of myeloid zinc finger 1 (MZF1) and miRNA-337-3p (miR-337-3p) within the MMP-14 promoter. We demonstrated that MZF1 directly bound to the MMP-14 promoter to facilitate its nascent transcription and expression in gastric cancer cell lines. In contrast, endogenous miR-337-3p suppressed the MMP-14 expression through recognizing its binding site within MMP-14 promoter. Mechanistically, miR-337-3p repressed the binding of MZF1 to MMP-14 promoter via recruiting Argonaute 2 and inducing repressive chromatin remodeling. Gain- and loss-of-function studies demonstrated that miR-337-3p suppressed the growth, invasion, metastasis, and angiogenesis of gastric cancer cells in vitro and in vivo through repressing MZF1-facilitated MMP-14 expression. In clinical specimens and cell lines of gastric cancer, MZF1 was highly expressed and positively correlated with MMP-14 expression. Meanwhile, miR-337-3p was under-expressed and inversely correlated with MMP-14 levels. miR-337-3p was an independent prognostic factor for favorable outcome of gastric cancer, and patients with high MZF1 or MMP-14 expression had lower survival probability. Taken together, these data indicate that miR-337-3p directly binds to the MMP-14 promoter to repress MZF1-facilitatd MMP-14 expression, thus suppressing the progression of gastric cancer.

Risk-Associated Long Noncoding RNA FOXD3-AS1 Inhibits Neuroblastoma Progression by Repressing PARP1-Mediated Activation of CTCF. Mol Ther 2017; 26:755-773.

Abstract
Neuroblastoma (NB) is the most common extracranial tumor in childhood. Recent studies have implicated the emerging roles of long noncoding RNAs (lncRNAs) in tumorigenesis and aggressiveness. However, the functions and targets of risk-associated lncRNAs in NB progression still remain to be determined. Herein, through mining of public microarray datasets, we identify lncRNA forkhead box D3 antisense RNA 1 (FOXD3-AS1) as an independent prognostic marker for favorable outcome of NB patients. FOXD3-AS1 is downregulated in NB tissues and cell lines, and ectopic expression of FOXD3-AS1 induces neuronal differentiation and decreases the aggressiveness of NB cells in vitro and in vivo. Mechanistically, as a nuclear lncRNA, FOXD3-AS1 interacts with poly(ADP-ribose) polymerase 1 (PARP1) to inhibit the poly(ADP-ribosyl)ation and activation of CCCTC-binding factor (CTCF), resulting in derepressed expression of downstream tumor-suppressive genes. Rescue experiments indicate that FOXD3-AS1 harbors tumor-suppressive properties by inhibiting the oncogenic roles of PARP1 or CTCF and plays crucial roles in all-trans-retinoic-acid-mediated therapeutic effects on NB. Administration of FOXD3-AS1 construct or siRNAs against PARP1 or CTCF reduces the tumor growth and prolongs the survival of nude mice. These findings suggest that as a risk-associated lncRNA, FOXD3-AS1 inhibits the progression of NB through repressing PARP1-mediated CTCF activation.

Abstract
OBJECTIVES The phytohormone methyl jasmonate (MeJA) has been identified as a vital cell regulator in plants. This substance is analogous to eicosanoids and similar to that of anti-inflammatory prostaglandins. In animals and in animal cells, it displayed an efficient neuroprotective, anti-inflammatory and antioxidant action; while in tumoral strains, it demonstrates a potentially highly attractive mechanism of apoptosis induction through various cellular and molecular mechanisms. The aim of the present review was to explore two new hypotheses that explain the action of MeJA, a lipid phytohormone and its potentially anti-apoptotic mechanism for use as a therapeutic target for future treatment of Inflammatory bowel diseases (IBDs). KEY FINDINGS Methyl jasmonate is a new candidate for the treatment of IBDs, modulating the expression of the major classes of caspase-type protease families that selectively act on the extrinsic and intrinsic pathways of the apoptotic process. Its action is based on the reduction of the expression in tumour necrosis factor tissue levels and the modulating action of reactive oxygen species production, acting only on the destruction of cells that express the diseased phenotype, and preserving cells that are not transformed. CONCLUSIONS Methyl jasmonate may represent an alternative for the transduction processes of important signals in the cellular renewal of the intestinal mucosa.

Abstract
Recent evidence shows the emerging roles of promoter-targeting endogenous microRNAs (miRNAs) in regulating gene transcription. However, miRNAs affecting the transcription of matrix metalloproteinase 14 (MMP-14) in gastric cancer remain unknown. Herein, through integrative mining of public datasets, we identified the adjacent targeting sites of Yin Yang 1 (YY1) and miRNA-584-3p (miR-584-3p) within MMP-14 promoter. We demonstrated that YY1 directly targeted the MMP-14 promoter to facilitate its expression in gastric cancer cells. In contrast, miR-584-3p recognized its complementary site within MMP-14 promoter to suppress its expression. Mechanistically, miR-584-3p interacted with Argonaute 2 to recruit enhancer of zeste homolog 2 and euchromatic histone lysine methyltransferase 2, resulting in enrichment of repressive epigenetic markers and decreased binding of YY1 to MMP-14 promoter. miR-584-3p inhibited the in vitro and in vivo tumorigenesis and aggressiveness of gastric cancer cells through repressing YY1-facilitated MMP-14 expression. In clinical gastric cancer tissues, the expression of YY1 and miR-584-3p was positively or negatively correlated with MMP-14 levels. In addition, miR-584-3p and YY1 were independent prognostic factors associated with favorable and unfavorable outcome of gastric cancer patients, respectively. These data demonstrate that miR-584-3p directly targets the MMP-14 promoter to repress YY1-facilitated MMP-14 expression and inhibits the progression of gastric cancer.

Abstract
Gastric cancer (GC) is one of the most common cancers and the second leading cause of cancer deaths in the world. Many factors have been reported regarding the progression and development of GC. In this study, we aimed to investigate the correlation of 3-phosphoinositide dependent protein kinase-1 (PDK-1) with cell viability, migration, and invasion of GC. The expression of PDK-1 was measured in different GC cell lines. Thereafter, the expression of PDK-1 was interfered by small hairpin RNA (shRNA) and then incubated with or without the inhibitor of nuclear factor-κB (NF-κB) pyrrolidine dithiocarbamate (PDTC). We then investigated the effects of PDK-1 aberrant expression on GC cell viability, migration, invasion, and the epithelial-mesenchymal transition (EMT) progress. The results showed that PDK-1 was highly expressed in GC cells, and PDK-1 promoted cell viability, migration, invasion, and EMT in GC. Moreover, we confirmed that PDK-1 activated the phosphatidylinositol 3-hydroxy kinase (PI3K)/AKT and NF-κB signaling pathways. However, administration of PDTC reversed the effects of overexpression of PDK-1 on cell migration and invasion. All these findings suggest that PDK-1 may be involved in progression of GC and could be a new therapeutic target for this disease.

Abstract
Methyl jasmonate has recently been found to have anti-cancer activity. Methyl jasmonate detached hexokinase 2 from a voltage dependent anion channel causing a reduction in mitochondrial transmembrane potential that led to the release of cytochrome C and apoptosis inducing factor resulting in intrinsic apoptosis. Blocked adenosine triphosphate synthesis caused by mitochondrial injury hampered oxidative phosphorylation and led to cell necrosis. The results were applied to the in vivo treatment of nude mice with a satisfactory effect. Collectively, our results suggest that methyl jasmonate may be an adjuvant therapy for liver tumors due to its mechanism in cancer cells compared to that in normal cells: The major function is to inhibit glycolysis instead of changing aerobic metabolism.

Abstract
Previous studies have indicated that as the only mammalian endo-β-D-glucuronidase, heparanase (HPSE) is up-regulated and associated with poor prognosis in gastric cancer, while the underlying mechanisms still remain to be determined. Herein, through integrative analysis of public datasets, we found microRNA-558 (miR-558) and SMAD family member 4 (Smad4) as the crucial transcription regulators of HPSE expression in gastric cancer, with their adjacent target sites within the promoter of HPSE. We identified that endogenous miR-558 activated the transcription and expression of HPSE in gastric cancer cell lines. In contrast, Smad4 suppressed the nascent transcription and expression of HPSE via directly binding to its promoter. Mechanistically, miR-558 recognized its complementary site within HPSE promoter to decrease the binding of Smad4 in an Argonaute 1-dependent manner. Ectopic expression or knockdown experiments indicated that miR-558 promoted the in vitro and in vivo tumorigenesis and aggressiveness of gastric cancer cell lines via attenuating Smad4-mediated repression of HPSE expression. In clinical gastric cancer specimens, up-regulation of miR-558 and down-regulation of Smad4 were positively correlated with HPSE expression. Kaplan–Meier survival analysis revealed that miR-558 and Smad4 were associated with unfavourable and favourable outcome of gastric cancer patients, respectively. Therefore, these findings demonstrate that miR-558 facilitates the progression of gastric cancer through directly targeting the HPSE promoter to attenuate Smad4-mediated repression of HPSE expression.

Abstract
Recent evidence shows the emerging roles of endogenous microRNAs (miRNAs) in repressing gene transcription. However, the miRNAs inhibiting the transcription of matrix metalloproteinase 14 (MMP-14), a membrane-anchored MMP crucial for the tumorigenesis and aggressiveness, still remain largely unknown. In this study, through mining computational algorithm program and genome-wide Argonaute profiling dataset, we identified one binding site of miRNA-337-3p (miR-337-3p) within the MMP-14 promoter. We demonstrated that miR-337-3p was under-expressed and inversely correlated with MMP-14 expression in clinical specimens and cell lines of neuroblastoma (NB), the most common extracranial solid tumor in childhood. Patients with high miR-337-3p expression had greater survival probability. miR-337-3p suppressed the promoter activity, nascent transcription, and expression of MMP-14, resulting in decreased levels of vascular endothelial growth factor, in cultured NB cell lines. Mechanistically, miR-337-3p recognized its binding site and recruited Argonaute 2 to facilitate the enrichment of repressive epigenetic markers and decrease the binding of RNA polymerase II and specificity protein 1 on the MMP-14 promoter. Gain- and loss-of-function studies demonstrated that miR-337-3p suppressed the growth, invasion, metastasis, and angiogenesis of NB cells in vitro and in vivo. In addition, restoration of MMP-14 expression rescued the NB cells from changes in these biological features. Taken together, these data indicate that miR-337-3p directly binds the MMP-14 promoter to repress its transcription, thus suppressing the progression of NB.

Abstract
Heparanase (HPSE) is the only endo-β-D-glucuronidase that is correlated with the progression of neuroblastoma (NB), the most common extracranial malignancy in childhood. However, the mechanisms underlying HPSE expression in NB still remain largely unknown. Herein, through analyzing cis-regulatory elements and mining public microarray datasets, we identified SMAD family member 4 (Smad4) as a crucial transcription regulator of HPSE in NB. We demonstrated that Smad4 repressed the HPSE expression at the transcriptional levels in NB cells. Mechanistically, Smad4 suppressed the HPSE expression through directly binding to its promoter and repressing the lymphoid enhancer binding factor 1 (LEF1)-facilitated transcription of HPSE via physical interaction. Gain- and loss-of-function studies demonstrated that Smad4 inhibited the growth, invasion, metastasis, and angiogenesis of NB cells in vitro and in vivo. Restoration of HPSE expression prevented the NB cells from changes in these biological features induced by Smad4. In clinical NB specimens, Smad4 was under-expressed and inversely correlated with HPSE levels, while LEF1 was highly expressed and positively correlated with HPSE expression. Patients with high Smad4 expression, low LEF1 or HPSE levels had greater survival probability. These results demonstrate that Smad4 suppresses the tumorigenesis and aggressiveness of NB through repressing the HPSE expression.

Abstract
Increasing evidence has shown that Chinese Herbal Medicine (CHM) has efficient therapeutic effects for advanced gastric adenocarcinoma, while the therapeutic mechanisms underlying this treatment remain unclear.In this study, the Kaplan-Meier method and Cox regression analysis were used to evaluate the survival benefit of CHM treatment, and correlation analysis was applied to identify the most effective components in the formulas. A network pharmacological approach was developed to decipher the potential therapeutic mechanisms of CHM.CHM treatment was an independent protective factor. The hazard ratio was 0.364 (95% CI 0.245-0.540; P < 0.001). The median survival time was 18 months for patients who received CHM treatment, while for patients without CHM treatment was decreased to 9 months (P < 0.001). Thirteen out of the total 204 herbs were significantly correlated with favorable survival outcomes (P < 0.05), likely representing the most effective components in these formulas. Bioinformatics analyses suggested that the simultaneous manipulation of multiple targets in proliferation pathways (such as epidermal growth factor receptor, fibroblast growth factor receptor 2, human epidermal growth factor receptor 2, proliferating cell nuclear antigen, and insulin like growth factor 2) and the process of cancer metastasis (collagen families, fibronectin 1 and matrix metalloproteinases families) might largely account for the mechanisms of the 13 herbs against gastric adenocarcinoma.A network pharmacology method was introduced to decipher the underlying mechanisms of CHM, which provides a good foundation for herbal research based on clinical data.

Abstract
Recent evidence shows the emerging roles of intelectin 1 (ITLN1), a secretory lectin, in human cancers. Our previous studies have implicated the potential roles of ITLN1 in the aggressiveness of gastric cancer. Herein, we investigated the functions, downstream targets, and clinical significance of ITLN1 in the progression of gastric cancer. We demonstrated that ITLN1 increased the levels of hepatocyte nuclear factor 4 alpha (HNF4α), resulting in suppression of nuclear translocation and transcriptional activity of β-catenin in gastric cancer cells. Mechanistically, ITLN1 attenuated the activity of nuclear factor-kappa B, a transcription factor repressing the HNF4α expression, in gastric cancer cells through inactivating the phosphoinositide 3-kinase/AKT/Ikappa B kinase signaling. Gain- and loss-of-function studies demonstrated that ITLN1 suppressed the growth, invasion, and metastasis of gastric cancer cells in vitro and in vivo. In addition, restoration of HNF4α expression prevented the gastric cancer cells from ITLN1-mediated changes in these biological features. In clinical gastric cancer tissues, HNF4α expression was positively correlated with that of ITLN1. Patients with high ITLN1 or HNF4α expression had greater survival probability. Taken together, these data indicate that ITLN1 suppresses the progression of gastric cancer through up-regulation of HNF4α, and is associated with improved survival in patients with gastric cancer.

Abstract
Membrane type 1-matrix metalloproteinase (MT1-MMP) is associated with enhanced tumorigenicity in many cancers. A recent study has revealed that MT1-MMP induces epithelial-to-mesenchymal transition (EMT) in prostate and breast cancer cells. However, its role in esophageal squamous cell carcinoma (ESCC) has not been studied. Here, we investigated the role of MT1-MMP in the dissemination of ESCC. Expression of MT1-MMP was detected by immunohistochemistry and tissue microarray in 88 Kazakh ESCC patients. Western blotting was performed to detect endogenous and overexpressed exogenous MT1-MMP in the Eca109 and Eca9706 cell lines, respectively. Transwell assay was used to estimate MT1-MMP-induced invasion and metastasis. EMT-associated proteins were detected by immunohistochemistry and western blotting. The associations between the expression of MT1-MMP and EMT-associated proteins with clinicopathologic parameters were analyzed. Overexpression of MT1-MMP was confirmed in Kazakh ESCC patients. MT1-MMP levels were found to be correlated with the depth of tumor infiltration. MT1-MMP induced EMT in ESCC both in vivo and in vitro, N-cadherin and Vimentin expression was upregulated upon MT1-MMP transfection into cells. However, E-cadherin was found to be downregulated. MT1-MMP-induced EMT led to increase migration and invasion in ESCC cell lines. In conclusion, our results suggest that MT1-MMP promotes ESCC invasion and metastasis.

Br J Surg 2016; 103:407-16. [PMID: 26805552 DOI: 10.1002/bjs.10066] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2015] [Revised: 06/11/2015] [Accepted: 10/27/2015] [Indexed: 12/14/2022]
Abstract
BACKGROUND The hypermethylation of ring finger protein (RNF) 180 DNA promoter is significantly associated with lymph node metastasis of gastric cancer. The present study explored the potential mechanism of RNF180-regulated lymph node metastasis of gastric cancer. METHODS Associations between clinicopathological and survival data and RNF180 expression in gastric cancer tissues were analysed. The effects of RNF180 re-expression on gastric cancer cells were determined by means of proliferation, invasion, growth and lymphangiogenesis assays. A genome microarray was used to find potential target genes associated with lymphatic metastasis of gastric cancer cells regulated by RNF180. RESULTS RNF180 was silenced or downregulated in 99 (73·9 per cent) of 134 gastric cancer tissues compared with 41·8 per cent of paired non-tumour tissues from patients. As an independent prognostic indicator of gastric cancer, RNF180 expression in gastric cancer tissues was negatively related to the number of metastatic lymph nodes. RNF180 was also downregulated in all seven gastric cancer cell lines examined. The re-expression of RNF180 in gastric cancer cells inhibited colony formation, proliferation, migration and invasion in vitro; re-expression of RNF180 also suppressed tumour growth and lymphangiogenesis in mice. Furthermore, re-expression of RNF180 downregulated the expression of hepatocyte growth factor, matrix metalloproteinase (MMP) 2, MMP-14, vascular endothelial growth factor C/D and chemokine receptor 7 in gastric cancer cells; it also downregulated the expression of podoplanin in tumour tissue of nude mice. CONCLUSION RNF180 appears to act as a suppressor gene that inhibits lymph node metastasis in gastric cancer. SURGICAL RELEVANCE Biological mechanisms that lead to lymph node metastasis in gastric cancer have not been clarified. Ring finger protein (RNF) 180 has been shown to participate in the processes of lymph node metastasis in several human malignancies. In this study, silencing or downregulation of RNF180 expression was significantly associated with lymph node metastasis of gastric cancer. In vitro, RNF180 expression suppressed the common biological characteristics of gastric cancer cells (HGC-27), including proliferation, invasion, lymphangio genesis and chemotaxis. RNF180 expression also inhibited tumour growth and tumour lymphangiogenesis in vivo. These results show that RNF180 is capable of inhibiting lymph node metastasis of gastric cancer by suppressing the intracellular activation of malignant molecular signals. Therefore, RNF180 could be considered as a promising biomarker for evaluation of the tumour aggressiveness and may be a target for future therapeutic intervention.

CTCF cooperates with noncoding RNA MYCNOS to promote neuroblastoma progression through facilitating MYCN expression. Oncogene 2015; 35:3565-76.

Abstract
Previous studies have indicated the important roles of MYCN in tumorigenesis and progression of neuroblastoma (NB), the most common extracranial solid tumor derived from neural crest in childhood. However, the regulatory mechanisms of MYCN expression in NB still remain largely unknown. In this study, through mining public microarray databases and analyzing the cis-regulatory elements and chromatin immunoprecipitation data sets, we identified CCCTC-binding factor (CTCF) as a crucial transcription factor facilitating the MYCN expression in NB. RNA immunoprecipitation, RNA electrophoretic mobility shift assay, RNA pull down and in vitro binding assay indicated the physical interaction between CTCF and MYCN opposite strand (MYCNOS), a natural noncoding RNA surrounding the MYNC promoter. Gain- and loss-of-function studies revealed that MYCNOS facilitated the recruitment of CTCF to its binding sites within the MYCN promoter to induce chromatin remodeling, resulting in enhanced MYCN levels and altered downstream gene expression, in cultured NB cell lines. CTCF cooperated with MYCNOS to suppress the differentiation and promote the growth, invasion and metastasis of NB cells in vitro and in vivo. In clinical NB tissues and cell lines, CTCF and MYCNOS were upregulated and positively correlated with MYCN expression. CTCF was an independent prognostic factor for unfavorable outcome of NB, and patients with high MYCNOS expression had lower survival probability. Taken together, these results demonstrate that CTCF cooperates with noncoding RNA MYCNOS to exhibit oncogenic activity that affects the aggressiveness and progression of NB through transcriptional upregulation of MYCN.

Abstract
Aerobic glycolysis, i.e., the Warburg effect, may contribute to the aggressive phenotype of hepatocellular carcinoma. However, increasing evidence highlights the limitations of the Warburg effect, such as high mitochondrial respiration and low glycolysis rates in cancer cells. To explain such contradictory phenomena with regard to the Warburg effect, a metabolic interplay between glycolytic and oxidative cells was proposed, i.e., the "reverse Warburg effect". Aerobic glycolysis may also occur in the stromal compartment that surrounds the tumor; thus, the stromal cells feed the cancer cells with lactate and this interaction prevents the creation of an acidic condition in the tumor microenvironment. This concept provides great heterogeneity in tumors, which makes the disease difficult to cure using a single agent. Understanding metabolic flexibility by lactate shuttles offers new perspectives to develop treatments that target the hypoxic tumor microenvironment and overcome the limitations of glycolytic inhibitors.

Abstract
Matrix metalloproteinase 14 (MMP-14) is a membrane-anchored MMP crucial for tumorigenesis and aggressiveness, and is highly expressed in neuroblastoma (NB), the most common extracranial solid tumor in childhood. Recent evidence shows the emerging roles of endogenous promoter-targeting microRNAs (miRNAs) in regulating gene transcription. However, the roles of miRNAs in the transcription of MMP-14 still remain largely unknown. In this study, through mining computational algorithm program and Argonaute-chromosome interaction dataset, we identified one binding site of miRNA-584-5p (miR-584-5p) within the MMP-14 promoter. In NB tissues, miR-584-5p was under-expressed and inversely correlated with MMP-14 expression, and was an independent prognostic factor for favorable outcome of patients. miR-584-5p precursor attenuated the expression of MMP-14 in a Dicer-dependent manner, resulting in decreased levels of vascular endothelial growth factor, in cultured NB cell lines. In addition, miR-584-5p suppressed the promoter activity of MMP-14, and mutation of miR-584-5p binding site abolished these effects. Mechanistically, miR-584-5p recruited Argonaute 2 to facilitate the enrichment of enhancer of zeste homolog 2, histone H3 lysine 27 trimethylation, and histone H3 lysine 9 dimethylation on MMP-14 promoter in NB cells, which was abolished by repressing the miR-584-5p-promoter interaction. Gain- and loss-of-function studies demonstrated that miR-584-5p suppressed the growth, invasion, metastasis, and angiogenesis of NB cells in vitro and in vivo. Moreover, restoration of MMP-14 expression rescued the NB cells from changes in these biological features. Taken together, these results indicate that promoter-targeting miR-584-5p exerts tumor suppressive functions in NB through repressing the transcription of MMP-14.

Abstract
A large family of vomeronasal receptors recognizes pheromone cues in many animals including most amphibia, reptiles, rhodents, and other mammals. Humans possess five vomeronasal-type 1 receptor genes (VN1R1-VN1R5), which code for proteins that are functional in recombinant expression systems. We used two different recombinant expression systems and identified Hedione as a ligand for the putative human pheromone receptor VN1R1 expressed in the human olfactory mucosa. Following the ligand identification, we employed functional magnetic resonance imaging (fMRI) in healthy volunteers to characterize the in vivo action of the VN1R1 ligand Hedione. In comparison to a common floral odor (phenylethyl alcohol), Hedione exhibited significantly enhanced activation in limbic areas (amygdala, hippocampus) and elicited a sex-differentiated response in a hypothalamic region that is associated with hormonal release. Utilizing a novel combination of methods, our results indicate that the putative human pheromone receptor VN1R1 is involved in extra-olfactory neuronal activations induced by the odorous substance Hedione. The activation of VN1R1 might play a role in gender-specific modulation of hormonal secretion in humans.

Intelectin 1 suppresses the growth, invasion and metastasis of neuroblastoma cells through up-regulation of N-myc downstream regulated gene 2. Mol Cancer 2015; 14:47. [PMID: 25889839 PMCID: PMC4359454 DOI: 10.1186/s12943-015-0320-6] [Citation(s) in RCA: 49] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2014] [Accepted: 02/09/2015] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Recent studies have revealed the potential roles of intelectin 1 (ITLN1) in tumorigenesis. However, its functions and underlying mechanisms in neuroblastoma (NB), the most common extracranial solid tumor in childhood, still remain largely unknown. METHODS Human neuroblastoma cell lines were treated with recombinant ITLN1 protein or stably transfected with ITLN1 expression and short hairpin RNA vectors. Gene expression and signaling pathway were detected by western blot and real-time quantitative RT-PCR. Gene promoter activity and transcription factor binding were detected by luciferase reporter and chromatin immunoprecipitation assays. Growth and aggressiveness of tumor cells were measured by MTT colorimetry, colony formation, scratch assay, matrigel invasion assay, and nude mice model. RESULTS Mining of public microarray databases revealed that N-myc downstream regulated gene 2 (NDRG2) was significantly correlated with ITLN1 in NB. Gain- and loss-of-function studies indicated that secretory ITLN1 facilitated the NDRG2 expression, resulting in down-regulation of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 9 (MMP-9), in NB cell lines SH-SY5Y, SK-N-BE(2), and SK-N-SH. Krüppel-like factor 4 (KLF4), a transcription factor crucial for NDRG2 expression, was up-regulated by ITLN1 in NB cells via inactivation of phosphoinositide 3-kinase (PI3K)/AKT signaling. Ectopic expression of ITLN1 suppressed the growth, invasion and metastasis of NB cells in vitro and in vivo. Conversely, knockdown of ITLN1 promoted the growth, invasion, and metastasis of NB cells. In addition, rescue experiments in ITLN1 over-expressed or silenced NB cells showed that restoration of NDRG2 expression prevented the tumor cells from ITLN1-mediated changes in these biological features. In clinical NB tissues, ITLN1 was down-regulated and positively correlated with NDRG2 expression. Patients with high ITLN1 or NDRG2 expression had greater survival probability. CONCLUSIONS These findings indicate that ITLN1 functions as a tumor suppressor that affects the growth, invasion and metastasis of NB through up-regulation of NDRG2.

Abstract
Heparanase (HPSE) is the endogenous endoglycosidase that degrades heparan sulfate proteoglycans and promotes the tumor growth, invasion, metastasis and angiogenesis. Our previous studies have shown that HPSE is highly expressed in neuroblastoma (NB), the most common extracranial solid tumor in childhood. However, the underlying regulatory mechanisms remain largely unknown. In this study, we identified one binding site of microRNA-558 (miR-558) within the HPSE promoter. In NB tissues and cell lines, miR-558 was up-regulated and positively correlated with HPSE expression. Gain- and loss-of-function studies demonstrated that miR-558 facilitated the transcript and protein levels of HPSE and its downstream gene, vascular endothelial growth factor, in NB cell lines. In addition, miR-558 enhanced the promoter activities of HPSE, and these effects were abolished by the mutation of the miR-558-binding site. Mechanistically, miR-558 induced the enrichment of the active epigenetic marker and RNA polymerase II on the HPSE promoter in NB cells in an Argonaute 1-dependent manner, which was abolished by repressing the miR-558-promoter interaction. Knockdown of endogenous miR-558 decreased the growth, invasion, metastasis and angiogenesis of NB cells in vitro and in vivo. In contrast, over-expression of miR-558 promoted the growth, invasion, metastasis and angiogenesis of SH-SY5Y and SK-N-SH cells. Restoration of HPSE expression prevented the NB cells from changes in these biological features induced by knockdown or over-expression of miR-558. These data indicate that miR-558 induces the transcriptional activation of HPSE via the binding site within promoter, thus facilitating the tumorigenesis and aggressiveness of NB.

Abstract
Methyl dihydrojasmonate (MJ) has been studied because of its application as an antitumor drug compound. However, as MJ is a poorly water-soluble compound, a suitable oil-in-water microemulsion (ME) has been studied in order to provide its solubilization in an aqueous media and to allow its administration by the parenteral route. The ME used in this work was characterized on the pseudo-ternary phase diagram by dynamic light scattering and rheological measurements. Regardless of the drug presence, the droplet size was directly dependent on the oil/surfactant (O/S) ratio. Furthermore, the drug incorporation into the ME significantly increased the ME diameter, mainly at low O/S ratios. The rheological evaluation of the systems showed that in the absence of drug a Newtonian behavior was observed. On the other hand, in the presence of MJ the ME systems revealed pseudoplastic behavior, independently of the O/S ratio. The in vivo studies demonstrated that not only was the effect on the tumor inhibition inversely dependent on the MJ-loaded ME administered dose, but also it was slightly higher than the doxorubicin alone, which was used as the positive control. Additionally, a small antiangiogenic effect for MJ-loaded ME was found at doses in which it possesses antitumor activity. MJ revealed to be nontoxic at doses higher than 350 mg/kg, which was higher than the dose that provides tumor-inhibition effect in this study. Because the MJ-loaded ME was shown to have anticancer activity comparable to doxorubicin, the ME described here may be considered a suitable vehicle for parenteral administration of MJ.

Abstract
Primary hits that arise from screening one bead one compound (OBOC) libraries against a target of interest rarely have high potency. However, there has been little work focused on the development of an efficient workflow for primary hit improvement. In this study, we show that by characterizing the binding constants for all of the hits that arise from a screen, structure-activity relationship (SAR) data can be obtained to inform the design of "derivative libraries" of a primary hit that can then be screened under more demanding conditions to obtain improved compounds. Here, we demonstrate the rapid improvement of a primary hit against matrix metalloproteinase-14 using this approach.

Abstract
Matrix metalloproteinase 14 (MMP-14) is the only membrane-anchored MMP that plays critical roles in tumorigenesis and aggressiveness. However, the regulatory mechanisms underlying the high MMP-14 expression in neuroblastoma (NB), a highly malignant tumor in childhood, still remain unclear. Herein, we applied an integrative approach to analyze the public datasets, and identified hepatocyte nuclear factor 4 alpha (HNF4α) as a crucial transcription factor facilitating the MMP-14 expression in NB. In clinical NB tissues, HNF4α was up-regulated and positively correlated with MMP-14 expression, and was an independent prognostic factor for unfavorable outcome of patients. Luciferase reporter and chromatin immunoprecipitation assays indicated that HNF4α directly targeted the binding site within the MMP-14 promoter to facilitate its transcription. Knockdown of HNF4α suppressed the invasion, metastasis and angiogenesis of NB cells in vitro and in vivo. Conversely, ectopic expression of HNF4α promoted the invasion, metastasis and angiogenesis of NB cells. Importantly, restoration of MMP-14 expression prevented the tumor cells from HNF4α-mediated changes in these biological features. Taken together, HNF4α exhibits oncogenic activity that affects the aggressiveness and angiogenesis of NB through activating the transcription of MMP-14.

Abstract
The transcription factor forkhead box D3 (FOXD3) plays a crucial role in the development of neural crest cells. However, the function and underlying mechanisms of FOXD3 in the progression of neuroblastoma (NB), an embryonal tumor that is derived from the neural crest, still remain largely unknown. Here, we report that FOXD3 is an important oncosuppressor of NB tumorigenicity and aggressiveness. We found that FOXD3 was down-regulated in NB tissues and cell lines. Patients with high FOXD3 expression have greater survival probability. Over-expression or knockdown of FOXD3 responsively altered both the protein and mRNA levels of N-myc downstream regulated 1 (NDRG1) and its downstream genes, vascular endothelial growth factor and matrix metalloproteinase 9, in cultured NB cell lines SH-SY5Y and SK-N-SH. Luciferase reporter and chromatin immunoprecipitation assays indicated that FOXD3 directly targeted the binding site within NDRG1 promoter to facilitate its transcription. Ectopic expression of FOXD3 suppressed the growth, invasion, metastasis and angiogenesis of SH-SY5Y and SK-N-SH cells in vitro and in vivo. Conversely, knockdown of FOXD3 promoted the growth, migration, invasion and angiogenesis of NB cells. In addition, rescue experiments in FOXD3 over-expressed or silenced NB cells showed that restoration of NDRG1 expression prevented the tumor cells from FOXD3-mediated changes in these biological features. Our results indicate that FOXD3 exhibits tumor suppressive activity that affects the growth, aggressiveness and angiogenesis of NB through transcriptional regulation of NDRG1.

Abstract
UNLABELLED Hepatocellular carcinoma (HCC) is a highly vascularized tumor with poor clinical outcome. Our previous work has shown that eukaryotic initiation factor 5A2 (EIF5A2) over-expression enhances HCC cell metastasis. In this study, EIF5A2 was identified to be an independent risk factor for poor disease-specific survival among HCC patients. Both in vitro and in vivo assays indicated that ablation of endogenous EIF5A2 inhibited tumor angiogenesis by reducing matrix metalloproteinase 2 (MMP-2) expression. Given that MMP-2 degrades collagen IV, a main component of the vascular basement membrane (BM), we subsequently investigated the effect of EIF5A2 on tumor vasculature remodeling using complementary approaches, including fluorescent immunostaining, transmission electron microscopy, tumor perfusion assays and tumor hypoxia assays. Taken together, our results indicate that EIF5A2 silencing increases tumor vessel wall continuity, increases blood perfusion and improves tumor oxygenation. Additionally, we found that ablation of EIF5A2 enhanced the chemosensitivity of HCC cells to 5-Fluorouracil (5-FU). Finally, we demonstrated that EIF5A2 might exert these functions by enhancing MMP-2 activity via activation of p38 MAPK and JNK/c-Jun pathways. CONCLUSION This study highlights an important role of EIF5A2 in HCC tumor vessel remodeling and indicates that EIF5A2 represents a potential therapeutic target in the treatment of HCC.

Abstract
AIM: To investigate the protein expression of MMP-14 and COX-2 in gastric cancer to further reveal the pathogenesis of gastric cancer.
METHODS: The protein expression of MMP-14 and COX-2 was examined by immunohistochemistry in human gastric cancer tissues and normal gastric tissues, and the relationship between the protein expression and clinicopathological features was analyzed. The protein expression of MMP-14 in human gastric cancer tissues at different TNM stages was also explored.
RESULTS: The expression rates of MMP-14 and COX-2 in gastric cancer tissues were significantly higher than those in normal tissues (P < 0.01). The expression of MMP-14 was significantly correlated with the degree of differentiation, lymph node metastasis, invasion depth and TNM stage of gastric cancer (P < 0.01). The expression of COX-2 was correlated with invasion depth and TNM stage of gastric cancer (P < 0.05). MMP-14 expression was positively correlated with COX-2 expression in gastric cancer tissues (P < 0.01). MMP-14 expression increased with the elevation of TNM stage and showed a tendency from the cytoplasm to cell membrane.
CONCLUSION: Stimulating overexpression and intracellular translocation of MMP-14 may be one of mechanisms for COX-2 protein to contribute to the invasion and metastasis of human gastric cancer.

Int J Cell Biol 2014; 2014:572097. [PMID: 24648844 PMCID: PMC3933403 DOI: 10.1155/2014/572097] [Citation(s) in RCA: 66] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2013] [Revised: 11/06/2013] [Accepted: 11/07/2013] [Indexed: 12/29/2022] Open
Abstract
Methyl jasmonate (MJ), an oxylipid that induces defense-related mechanisms in plants, has been shown to be active against cancer cells both in vitro and in vivo, without affecting normal cells. Here we review most of the described MJ activities in an attempt to get an integrated view and better understanding of its multifaceted modes of action. MJ (1) arrests cell cycle, inhibiting cell growth and proliferation, (2) causes cell death through the intrinsic/extrinsic proapoptotic, p53-independent apoptotic, and nonapoptotic (necrosis) pathways, (3) detaches hexokinase from the voltage-dependent anion channel, dissociating glycolytic and mitochondrial functions, decreasing the mitochondrial membrane potential, favoring cytochrome c release and ATP depletion, activating pro-apoptotic, and inactivating antiapoptotic proteins, (4) induces reactive oxygen species mediated responses, (5) stimulates MAPK-stress signaling and redifferentiation in leukemia cells, (6) inhibits overexpressed proinflammatory enzymes in cancer cells such as aldo-keto reductase 1 and 5-lipoxygenase, and (7) inhibits cell migration and shows antiangiogenic and antimetastatic activities. Finally, MJ may act as a chemosensitizer to some chemotherapics helping to overcome drug resistant. The complete lack of toxicity to normal cells and the rapidity by which MJ causes damage to cancer cells turn MJ into a promising anticancer agent that can be used alone or in combination with other agents.
