The Inflammatory Cytokine Profile of Patients with Malignant Pleural Effusion Treated with Pleurodesis. J Clin Med 2020; 9:jcm9124010. [PMID: 33322487 PMCID: PMC7763363 DOI: 10.3390/jcm9124010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 11/30/2020] [Accepted: 12/09/2020] [Indexed: 12/27/2022] Open
Abstract
Patients with malignant pleural effusion (MPE) who underwent successful pleurodesis survive longer than those for whom it fails. We hypothesize that the therapy-induced inflammatory responses inhibit the cancer progression, and thereby lead to a longer survival. Thirty-three consecutive patients with MPE that were eligible for bleomycin pleurodesis between September 2015 and December 2017 were recruited prospectively. Nineteen patients (57.6%) achieved fully or partially successful pleurodesis, while 14 patients either failed or survived less than 30 days after pleurodesis. Two patients without successful pleurodesis were excluded because of missing data. Interleukin (IL)-1 beta, IL-6, IL-10, transforming growth factor beta, tumor necrosis factor alpha (TNF-α), and vascular endothelial growth factor in the pleural fluid were measured before, and after 3 and 24 h of pleurodesis. Their pleurodesis outcome and survival were monitored and analyzed. Patients who underwent successful pleurodesis had a longer survival rate. Patients without successful pleurodesis had significantly higher TNF-α and IL-10 levels in their pleural fluid than in the successful patients before pleurodesis. Following pleurodesis, there was a significant increment of IL-10 in the first three hours in the successful patients. In contrast, significant increments of TNF-α and IL-10 were found in the unsuccessful patients between 3 and 24 h after pleurodesis. The ability to produce specific cytokines in the pleural space following pleurodesis may be decisive for the patient’s outcome and survival. Serial measurement of cytokines can help allocate the patients to adequate treatment strategies. Further study of the underlying mechanism may shed light on cytokine therapies as novel approaches.

Abstract
Interest in the use of cell-free nucleic acids (CFNAs) as clinical non-invasive biomarker panels for prediction and prevention of multiple diseases has greatly increased over the last decade. Indeed, circulating CFNAs are attributable to many physiological and pathological processes such as imbalanced stress conditions, physical activities, extensive apoptosis of different origin, systemic hypoxic-ischemic events and tumour progression, amongst others. This article highlights the involvement of circulating CFNAs in local and systemic processes dealing with the question, whether specific patterns of CFNAs in blood, their detection, quantity and quality (such as their methylation status) might be instrumental to predict a disease development/progression and could be further utilised for accompanying diagnostics, targeted prevention, creation of individualised therapy algorithms, therapy monitoring and prognosis. Presented considerations conform with principles of 3P medicine and serve for improving individual outcomes and cost efficacy of medical services provided to the population.

Abstract
Numerous studies have confirmed the coexistence of oxidative stress and inflammatory processes. Long-term inflammation and oxidative stress may significantly affect the initiation of the neoplastic transformation process. Here, we describe the synthesis of a new series of Mannich base-type hybrid compounds containing an arylpiperazine residue, 1,3,4-oxadiazole ring, and pyridothiazine-1,1-dioxide core. The synthesis was carried out with the hope that the hybridization of different pharmacophoric molecules would result in a synergistic effect on their anti-inflammatory activity, especially the ability to inhibit cyclooxygenase. The obtained compounds were investigated in terms of their potencies to inhibit cyclooxygenase COX-1 and COX-2 enzymes with the use of the colorimetric inhibitor screening assay. Their antioxidant and cytotoxic effect on normal human dermal fibroblasts (NHDF) was also studied. Strong COX-2 inhibitory activity was observed after the use of TG6 and, especially, TG4. The TG11 compound, as well as reference meloxicam, turned out to be a preferential COX-2 inhibitor. TG12 was, in turn, a non-selective COX inhibitor. A molecular docking study was performed to understand the binding interaction of compounds at the active site of cyclooxygenases.

Abstract
Dysregulation of SUMO modification is linked to carcinogenesis. UBC9 is the sole conjugating enzyme in sumoylation and plays a pivotal role in maintaining homeostasis and restraining stress reactions. However, the clinical significance and function of UBC9 in bladder cancer remain unclear. In this study, immunohistochemistry was used to determine the expression of UBC9. UBC9 knock-down and SUMO inhibition were conducted followed by proliferation, migration, and cell cycle assays. RNA sequencing and bioinformatic analysis were used to identify potential mechanisms of UBC9. Cytokine membrane antibody array was used to detect the expression of cytokine. The mass cytometry TOF (CyTOF) was used to explore the association between bladder cancer stem cell-like population and UBC9 expression. Our results showed that UBC9 played a dual role in bladder cancer. UBC9 was up-regulated in bladder cancer, but was negatively correlated with TNM stage and grade. Knocking-down of UBC9 resulted in dramatic activation of inflammatory gene expression, which might cause inhibition of cell proliferation and inducing cell apoptosis. IL6 was the hub gene in UBC9 regulatory network. Markedly up-regulated IL6 after knocking-down of UBC9 activated the expression of CD44, which was a prominent marker of cancer stem cells. Thus, our results revealed an important and previously undescribed role for UBC9 in modulation of inflammatory signaling of bladder cancer. UBC9 in bladder cancer cells is required to maintain high sumoylation levels and alleviate stress-related inflammation threats to cell survival. Lacking UBC9 contributes to inflammation activation, epithelial-mesenchymal transition and stem cell-like population formation, leading to cancer progression.

Abstract
Accumulating evidence suggests that inflammation is present in solid tumors. However, it is poorly understood whether inflammation exists in glioma and how it affects the metabolic signature of glioma. By analyzing immunohistochemical data and gene expression data downloaded from bioinformatic datasets, the present study revealed an accumulation of inflammatory cells in glioma, activation of microglia, upregulation of proinflammatory factors (including IL-6, IL-8, hypoxia-inducible factor-1α, STAT3, NF-κB1 and NF-κB2), destruction of mitochondrial structure and altered expression levels of electron transfer chain complexes and metabolic enzymes. By monitoring glioma cells following proinflammatory stimulation, the current study observed a remodeling of their mitochondrial network via mitochondrial fission. More than half of the mitochondria presented ring-shaped or spherical morphologies. Transmission electron microscopic analyses revealed mitochondrial swelling with partial or total cristolysis. Furthermore, proinflammatory stimuli resulted in increased generation of reactive oxygen species, decreased mitochondrial membrane potential and reprogrammed metabolism. The defective mitochondria were not eliminated via mitophagy. However, cell viability was not affected, and apoptosis was decreased in glioma cells after proinflammatory stimuli. Overall, the present findings suggested that inflammation may be present in glioma and that glioma cells may be resistant to inflammation-induced mitochondrial dysfunction.

Abstract
Obesity and related metabolic disorders, including chronic inflammation and enhanced oxidative stress, are closely associated with the development and progression of colorectal cancer. Previous epidemiological studies have demonstrated that increased serum uric acid is associated with the risk for various types of cancer, including colon cancer. This study examined the effects of a xanthine oxidase inhibitor allopurinol, widely used as a uric acid lowering medicine, on colorectal tumorigenesis in obese mice. Male C57BL/KsJ-db/db mice were injected with azoxymethane (15 mg/kg body weight) and then received drinking water containing allopurinol (30 mg/kg body weight) for fourteen weeks. At the time of sacrifice, allopurinol treatment significantly inhibited the development of colonic premalignant lesions. In the allopurinol-treated group, cellular proliferation in colonic mucosa was significantly suppressed, which was evaluated by the expression of proliferating cell nuclear antigen. Allopurinol also inhibited macrophage infiltration in the adipose tissue and decreased the serum level of TNF-α. The values of oxidative stress markers were markedly decreased in the allopurinol-treated group compared to those in the control group. These findings suggest that allopurinol attenuated chronic inflammation and decreased oxidative stress, preventing the development of colonic pre-neoplastic lesions in obesity-associated colon tumorigenesis model.

Abstract
As a consequence of military operations, many veterans suffer from penetrating wounds and long-term retention of military-grade heavy metal fragments. Fragments vary in size and location, and complete surgical removal may not be feasible or beneficial in all cases. Increasing evidence suggests retention of heavy metal fragments may have serious biological implications, including increased risks for malignant transformation. Previous studies assessed the tumorigenic effects of metal alloys in rats, demonstrating combinations of metals are sufficient to induce tumor formation after prolonged retention in skeletal muscle tissue. In this study, we analyzed transcriptional changes in skeletal muscle tissue in response to eight different military-relevant pure metals over 12 mo. We found that most transcriptional changes occur at 1 and 3 mo after metal pellets are embedded in skeletal muscle and these effects resolve at 6 and 12 mo. We also report significant immunogenic effects of nickel and cobalt and suppressive effects of lead and depleted uranium on gene expression. Overall, skeletal muscle exhibits a remarkable capacity to adapt to and recover from internalized metal fragments; however, the cellular response to chronic exposure may be restricted to the metal-tissue interface. These data suggest that unless affected regions are specifically captured by biopsy, it would be difficult to reliably detect changes in muscle gene expression that would be indicative of long-term adverse health outcomes.

Abstract
Over the past decade, it has been well established that tumorigenesis is affected by chronic inflammation. During this event, proinflammatory cytokines are produced by numerous types of cells, such as fibroblasts, endothelial cells, macrophages, and tumor cells, and are able to promote the initiation, progression, and metastasis of different types of cancer. When persistent inflammation occurs, activation of inflammasome complexes is initiated, leading to its assembly and further activation of caspase, production of proinflammatory cytokines, and pyroptosis induction. The function of this multiprotein complex is not only to reassure inflammation and to promote cell death, through caspase activity, but also has been identified to have significant contributions during tumorigenesis and cancer development. So far, many efforts have been made in order to extend the knowledge of inflammasome implications and how its components could be targeted as therapeutic agents. Additionally, microRNAs (miRNAs), evolutionary conserved noncoding molecules, have emerged as pivotal players during numerous biological events by regulating gene and protein expression. Therefore, dysregulations of miRNA expressions have been correlated with inflammation during tumor development. In this review, we aim to highlight the dual role of inflammasomes and proinflammatory cytokines during carcinogenesis paired with the distinguished effects of miRNAs upon inflammation cascades during tumor growth and progression.

Abstract
BACKGROUND Lung cancer is a frequent comorbidity of chronic obstructive pulmonary disease (COPD). However, the local risk of developing lung cancer related to regional emphysema distribution and clinical outcome has not been investigated. Our aim was to evaluate the impact of regional emphysema score (RES) on tumor location and prognosis in non-small cell lung cancer (NSCLC) patients. METHODS We enrolled 457 patients who underwent curative surgery for NSCLC at seven hospitals at The Catholic University of Korea from 2014 to 2018. Emphysema was visually assessed for each lobe, with the lingula as a separate lobe. Semi-quantitative emphysema scoring was classified as follows: 0 = none, 0.5 = 1 to 10%, 1 = 11 to 25%, 2 = 26 to 50%, 3 = 51 to 75%, and 4 = 76 to 100%. An RES was given to each of the six lung zone: the upper, middle, and lower lobes in the right and left lungs. RESULTS There were 145 patients in the high RES (≥ 3) group and 312 in the low RES (< 3) group. The mean RES in each lobe with cancer was significantly higher than that in other lobes without cancer (0.51 vs. 0.37, P < 0.001). This group showed significantly shorter disease-free survival (P < 0.001), in addition, presence of COPD, low diffusing capacity of the lung for carbon monoxide (< 80), smoking status, and poor differentiation were more frequent in this group. Also, cancer in a lobe with a higher RES (odds ratio (OR) = 1.56; 95% confidence interval (CI:1.01-2.42; P = 0.04), pathologic stage ≥ III (OR = 2.23; 95% CI: 1.28-3.89; P < 0.001), and poor differentiation (OR = 1.99; 95% CI: 1.22-3.21; P < 0.001) were independent factors for tumor recurrence. CONCLUSIONS The regional severity of emphysema by visual qualification was associated with the location of lung cancer, and was an independently poor prognostic factor for tumor recurrence in completely resected NSCLC patients.

Abstract
Inflammatory diseases remain critical health problems worldwide. The search for anti-inflammatory drugs is a primary activity in the pharmaceutical industry. Cacalol is a sesquiterpene with anti-inflammatory potential that is isolated from Psacalium decompositum, a medicinal plant with several scientific reports supporting its anti-inflammatory activity. Cacalol acetate (CA) is the most stable form. Nevertheless, the participation of CA in the main signaling pathway associated with inflammation is unknown. Our aim was to study the anti-inflammatory effect of CA and to determine its participation in NF-κB signaling. In TPA-induced edema in mice, CA produced 70.3% inhibition. To elucidate the influence of CA on the NF-κB pathway, RAW 264.7 macrophages were pretreated with CA and then stimulated with LPS, evaluating NF-ΚB activation, IKK phosphorylation, IΚB-α, p65, cytokine expression, and COX-2 release and activity. CA inhibited NF-κB activation and its upstream signaling, decreasing phosphorylation IKB-α and p65 levels. CA also reduced expression and secretion of TNF-α, IL-1β, and IL-6. Additionally, it decreased the activity and expression of COX-2 mRNA. These data support that CA regulates the NF-κB signaling pathway, which might explain, at least in part, its anti-inflammatory effect. CA is a bioactive molecule useful for the development of anti-inflammatory agents with innovative mechanisms of action.

Abstract
Uncertainties regarding optimized air pollution control remain as the underlying mechanisms of city-specific ambient particulate matter (PM)-induced health effects are unknown. Here, water-soluble extracts of PMs collected from four global cities via automobile air-conditioning filters were consecutively injected three times by an amount of 1, 2, and 2 mg into the blood circulation of Wistar rats after filtration by a 0.45 μm pore size membrane. Acute health effects, such as immune and inflammatory responses and hemorrhage in alveoli, were observed right after the PM extraction injection. Significant differences between cities in biomarker tumor necrosis factor-α (TNF-α) and monocyte chemoattractant protein-1 (MCP-1) levels were detected following the second and third PM injections. Rats' inflammatory responses varied substantially with the injections of city-specific PMs. Repeated PM extract exposure rendered the rats more vulnerable to subsequent challenges, and downregulation of certain microRNAs was observed in rats. Among the studied miRNAs, miR-125b, and miR-21 were most sensitive to the PM exposure, exhibiting a negative dose-response-type relationship with a source-specific PM (oxidative potential) toxicity (r2 = 0.63 and 0.57; p-values < 0.05). The results indicated that city-specific PMs could induce different health effects by selectively regulating different miRNAs, and that certain microRNAs, e.g., miR-125b and miR-21, may be externally mediated to neutralize PM-related health damages.

Chemical carcinogen safety testing: OECD expert group international consensus on the development of an integrated approach for the testing and assessment of chemical non-genotoxic carcinogens. Arch Toxicol 2020; 94:2899-2923.

Abstract
While regulatory requirements for carcinogenicity testing of chemicals vary according to product sector and regulatory jurisdiction, the standard approach starts with a battery of genotoxicity tests (which include mutagenicity assays). If any of the in vivo genotoxicity tests are positive, a lifetime rodent cancer bioassay may be requested, but under most chemical regulations (except plant protection, biocides, pharmaceuticals), this is rare. The decision to conduct further testing based on genotoxicity test outcomes creates a regulatory gap for the identification of non-genotoxic carcinogens (NGTxC). With the objective of addressing this gap, in 2016, the Organization of Economic Cooperation and Development (OECD) established an expert group to develop an integrated approach to the testing and assessment (IATA) of NGTxC. Through that work, a definition of NGTxC in a regulatory context was agreed. Using the adverse outcome pathway (AOP) concept, various cancer models were developed, and overarching mechanisms and modes of action were identified. After further refining and structuring with respect to the common hallmarks of cancer and knowing that NGTxC act through a large variety of specific mechanisms, with cell proliferation commonly being a unifying element, it became evident that a panel of tests covering multiple biological traits will be needed to populate the IATA. Consequently, in addition to literature and database investigation, the OECD opened a call for relevant assays in 2018 to receive suggestions. Here, we report on the definition of NGTxC, on the development of the overarching NGTxC IATA, and on the development of ranking parameters to evaluate the assays. Ultimately the intent is to select the best scoring assays for integration in an NGTxC IATA to better identify carcinogens and reduce public health hazards.

Abstract
Adenosine is a purine nucleoside, resulting from the degradation of adenosine triphosphate (ATP). Under adverse conditions, including hypoxia, ischemia, inflammation, or cancer, the extracellular levels of adenosine increase significantly. Once released, adenosine activates cellular signaling pathways through the engagement of the four known G-protein-coupled receptors, adenosine A1 receptor subtype (A1), A2A, A2B, and A3. These receptors, expressed virtually on all immune cells, mitigate all aspects of immune/inflammatory responses. These immunosuppressive effects contribute to blunt the exuberant inflammatory responses, shielding cells, and tissues from an excessive immune response and immune-mediated damage. However, a prolonged persistence of increased adenosine concentrations can be deleterious, participating in the creation of an immunosuppressed niche, ideal for neoplasia onset and development. Based on this evidence, the present review has been conceived to provide a comprehensive and critical overview of the involvement of adenosine system in shaping the molecular mechanisms underlying the enteric chronic inflammation and in promoting the generation of an immunosuppressive niche useful for the colorectal tumorigenesis.

Abstract
Epigenetic mechanisms comprising DNA methylation, histone modifications, and noncoding RNAs affect chromatin structure and regulate gene expression. These mechanisms control normal embryonic development and adult life and their deregulation contributes to several diseases including cancer. The process of tumorigenesis is complex and results from the evolution of different "hallmarks of cancer". Hanahan and Weinberg presented in 2000 and 2011 seminal contributions in the cancer field, first the six hallmarks of cancer and a decade later two additional hallmarks and two enabling characteristics were added. Here, we surmise that epigenetic mechanisms regulate and contribute to every single hallmark in cancer, and thus represent the hallmark of hallmarks in tumorigenesis. Focusing on epigenetics as a major hallmark in cancer formation has profound preventive, therapeutic, and clinical implications.

Abstract
Background: There is growing evidence showing a putative association between high-risk human papillomavirus (HR-HPV) infection and an increased risk of PCa.Objective: The aim of the current meta-analysis was to evaluate the association between HPV infection and PCa risk.Methods: This analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. We included all studies on HPV DNA or antibodies detected in biopsy tissues or sera. Available data were extracted from the article, including means and standard deviations in all case-control groups.Results: Thirty studies that investigated the link between HPV-16 and -18 were identified as eligible for this systematic review and meta-analysis, including a total of 6321 participants. The pooled OR showed increased risk of PCa (OR =1.37; p < .01) in men positive for HPV-16. There were seven studies with 2391 PCa cases and 4059 controls investigating the association between HPV-18 infection and PCa risk. Significant heterogeneity between study was found in the pooled analyzes. The pooled OR did not show increased risk of PCa (OR =0.80; p = .49) in men positive for HPV-18.Conclusions: This meta-analysis suggests that HPV-16 infection could represent a risk factor for PCa, whereas we found no such association for HPV-18. Further well-conducted studies could be useful to confirm this conclusion.

Abstract
The commensal microbiome of humans has co-evolved for thousands of years. The microbiome regulates human health and is also linked to several diseases, including cancer. The advances in next-generation sequencing have significantly contributed to our understanding of the microbiome and its association with cancer and cancer therapy. Recent studies have highlighted a close relationship of the microbiome to the pharmacological effect of chemotherapy and immunotherapy. The chemo-drugs usually interfere with the host immune system and reduces the microbiome diversity inside the body, which in turn leads to decreased efficacy of these drugs. The human microbiome, specifically the gut microbiome, increases the potency of chemo-drugs through metabolism, enzymatic degradation, ecological differences, and immunomodulation. Recent research exploits the involvement of microbiome to shape the efficacy and decrease the toxicity of these chemo-drugs. In this review, we have highlighted the recent development in understanding the relationship of the human microbiome with cancer and also emphasize on various roles of the microbiome in the modulation of cancer therapy. Additionally, we also summarize the ongoing research focussed on the improved efficacy of chemotherapy and immunotherapy using the host microbiome.

Abstract
Background This study is aimed at identifying unknown clinically relevant genes involved in colorectal cancer using bioinformatics analysis. Methods Original microarray datasets GSE107499 (ulcerative colitis), GSE8671 (colorectal adenoma), and GSE32323 (colorectal cancer) were downloaded from the Gene Expression Omnibus. Common differentially expressed genes were filtered from the three datasets above. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed, followed by construction of a protein-protein interaction network to identify hub genes. Kaplan-Meier survival analysis and TIMER database analysis were used to screen the genes related to the prognosis and tumour-infiltrating immune cells of colorectal cancer. Receiver operating characteristic curves were used to assess whether the genes could be used as markers for the diagnosis of ulcerative colitis, colorectal adenoma, and colorectal cancer. Results A total of 237 differentially expressed genes common to the three datasets were identified, of which 60 were upregulated, 125 were downregulated, and 52 genes that were inconsistently up- and downregulated. Common differentially expressed genes were mainly enriched in the cellular component of extracellular exosome and integral component of membrane categories. Eight hub genes, i.e., CXCL3, CXCL8, CEACAM7, CNTN3, SLC1A1, SLC16A9, SLC4A4, and TIMP1, were related to the prognosis and tumour-infiltrating immune cells of colorectal cancer, and these genes have diagnostic value for ulcerative colitis, colorectal adenoma, and colorectal cancer. Conclusion Three novel genes, CNTN3, SLC1A1, and SLC16A9 were shown to have diagnostic value with respect to the occurrence of colorectal cancer and should be verified in future studies.

Abstract
Cancer cells underlie the dysregulated metabolism of carbohydrate, lipid and protein and thereby, employ interconnected cross-linked signaling pathways to supply adequate energy for growth and related biosynthetic procedures. In the present study, a comprehensive review of cancer metabolism and anthocyanin's effect was conducted using the existing electronic databases, including Medline, PubMed, Scopus, and Web of Science, as well as related articles in the field. Such keywords as "cancer", and "cancer metabolism" in the title/abstract/keyword and all the "anthocyanins" in the whole text were used. Data were collected without time restriction until February 2020. The results indicated the involvement of several signaling pathways, including inflammatory PI3K/Akt/mTOR pathway, Bax/Bcl-2/caspases as apoptosis modulators, and NF-κB/Nrf2 as oxidative stress mediators in the cancer dysregulated metabolism. Compelling studies have shown that targeting these pathways, as critical hallmarks of cancer, plays a critical role in combating cancer dysregulated metabolism. The complexity of cancer metabolism signaling pathways, along with toxicity, high costs, and resistance to conventional drugs urge the need to investigate novel multi-target agents. Increasing evidence has introduced plant-derived secondary metabolites as hopeful anticancer candidates which target multiple dysregulated cross-linked pathways of cancer metabolism. Amongst these metabolites, anthocyanins have demonstrated positive anticancer effects by targeting inflammation, oxidative stress, and apoptotic signaling pathways. The current study revealed the cross-linked signaling pathways of cancer metabolism, as well as the promising pharmacological mechanisms of anthocyanins in targeting the aforementioned signaling mediators. To overcome the pharmacokinetic limitations of anthocyanins in cancer treatment, their interactions with gut microbiota and the need to develop related nano-formulations were also considered.

Abstract
Background Inflammation is the most common health problem faced in life relating to a vast number of diseases. The present study evaluated the pharmacological effect of three plants (Vitex thyrsiflora, Entandrophragma cylindricum, and Anonidium mannii) commonly used in the Cameroon pharmacopeia for the management of inflammatory response. Methods The pharmacological effect was characterized by the antioxidant capacity, anti-inflammatory, analgesic, and antipyretic properties of the ethanol extracts of the three plants. Antioxidant capacity was determined using total phenolic content, total flavonoid content, hydrogen peroxide, ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) radical scavenging assays. Anti-inflammatory activity was evaluated in vitro by protein denaturation and hypotonic-induced hemolysis methods and in vivo by carrageenan paw edema method. Analgesic and antipyretic activities were studied in vivo using acetic acid-induced writhing and brewer's yeast-induced hyperpyrexia models. Results All selected extracts showed high phenolic (15.93-64.45 mgCAE/g) and flavonoid (336.03-1053.48 mgCAE/g) contents and high ferric reducing power (288.75-364.91 mgCAE/g). These extracts exhibited good DPPH (IC50 = 0.30-1.65 μg/mL), ABTS (IC50 = 0.52-1.90 μg/mL), and H2O2 (IC50 = 1.40-3.55 μg/mL) radical scavenging activities. All extracts inhibited protein denaturation (6.79-82.27%) and protected the erythrocyte membrane from lysis induced by hypotonic solution (18.90-88.00%). The extracts significantly reduced dose-dependent paw edema (p < 0.05), fever, and abdominal writhing (p < 0.001) especially at 400 mg/kg. Conclusions All extracts exhibited interesting antioxidant properties, as well as significant anti-inflammatory, analgesic, and antipyretic effects.

Abstract
In recent years, bladder cancer (BC) has been reported as one of the most commonly occurring cancers among older people, and its detection is still difficult. Therefore, there is a need to search for additional useful markers of disease. Some studies indicate the important roles of inflammation and oxidative stress (OS) in bladder tumour pathogenesis. The aim of this study was to examine the levels of selected markers of OS, inflammation and angiogenesis in blood plasma/serum samples derived from patients with BC, and a healthy control group. Moreover the degrees of change and strength of correlation between values of the analysed markers and tumour stage or grade were estimated. Concentrations of: malondialdehyde (MDA) and advanced oxidation protein products (AOPP), and total antioxidant status (TAS) divided into slow (TAS-s) and fast (TAS-f) antioxidants (spectrophotometric measurement), angiogenin (ANG) (immunoenzymatic method) and C-reactive protein (CRP) (immunoturbidimetric method) were determined in both the studied groups. The majority of values of the examined parameters were significantly higher among patients, while subfractions of TAS were significantly lower in comparison to the control group. Moreover, different values and different strengths of correlation between the examined parameters and cancer stage or grade were noticed. The most significant changes for CRP were observed in T2 and for MDA in G3, while the lowest TAS-f activity was revealed in G1 patients. Increased values of OS parameters, angiogenesis and inflammation markers, in combination with reduced TAS subfractions activity in BC are important in its pathogenesis and will be helpful in estimation of patients' condition.

Abstract
Chronic obstructive pulmonary disease (COPD) and lung cancer are two major diseases of the lung with high rate of mortality, mostly among tobacco smokers. The glycosylation patterns of various plasma proteins show significant changes in COPD and subsequent hypoxia, inflammation and lung cancer, providing promising opportunities for screening aberrant glycan structures contribute to early detection of both diseases. Glycoproteins associated with COPD and lung cancer consist of highly sialylated N-glycans, which play an important role in inflammation whereby hypoxia leads to accumulation of sialyl Lewis A and X glycans. Although COPD is an inflammatory disease, it is an independent risk factor for lung cancer. Marked decrease in galactosylation of plasma immunoglobulin G (IgG) together with increased presence of sialic acids and more complex highly branched N-glycan structures are characteristic for COPD and lung cancer. Numerous glycan biomarkers have been discovered, and analysis of glycovariants associated with COPD and lung cancer has been carried out. In this paper we review fundamental glycosylation changes in COPD and lung cancer glycoproteins, focusing on IgG to provide an opportunity to distinguish between the two diseases at the glycoprotein level with diagnostic value.

Abstract
Although extensive research progress has been made in breast cancer in recent years, yet the morbidity and mortality rates of breast cancer are rising, making it the major disease that endangers women's health. Energy metabolism reprogramming is featured by a state termed "aerobic glycolysis" or the Warburg effect that glycolysis is preferred even under aerobic conditions in neoplastic diseases. Widely acknowledged as an emerging hallmark in cancers, this metabolic switch shows a sophisticated role in the pathogenesis of breast cancer. The regulating effect of non-coding RNAs (ncRNAs) composed of microRNAs, long non-coding RNAs and circular RNAs is closely related to the glycolysis in breast cancer. Therefore, understand the mechanisms of ncRNAs of aerobic glycolysis in breast cancer may provide new strategy for the disease.

[PMID: 31750910 DOI: 10.1093/ibd/izz281] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND Interleukin (IL)-6/signal transducers and activators of transcription 3 (STAT3) signaling plays an important role in the development of colitis-associated colorectal cancer (CAC). The mechanism of CAC formation remains unclear, and the relationship between miRNAs and the IL-6/STAT3 signaling pathway in the development of CAC is not well understood. In this study, we investigated the relationship between miR-29a-5p and the IL-6/STAT3 signaling pathway in the development of CAC and alterations in 10-11 translocations (TETs) regulated by this network. METHODS miR-29a-5p was screened in a CAC mouse model by high-throughput microarray analysis and investigated in human colorectal cancer tissue samples and colon cell lines by quantitative reverse transcription polymerase chain reaction (Q-RTPCR). The expression of miR-29a and TETs was detected by Q-RTPCR, and the expression of STAT3/P-STAT3 and TET3 was detected via Western blot assay. The expression of TET1 and 5-hydroxymethylcytosine (5hmC) was detected through immunofluorescence. RESULTS Our results showed that miR-29a-5p was significantly upregulated and was accompanied by STAT3 activation in the colon tissues of CAC mouse and human colorectal cancer tissues, as compared with normal colon tissues. In contrast, the levels of TETs and 5hmC were decreased. In vitro, overexpression of miR-29a-5p in colonic cell lines (HCT-116 and IEC-6) and RAW264.7 cells increased STAT3 expression, but decreased that of TET3, TET1, and 5hmC. miR-29a-5p downregulation in HCT-116 and IEC-6 cell lines could rescue the expression of STAT3 and TET3. Notably, STAT3 activation induced by IL-6 upregulated miR-29a-5p expression and reduced TET expression in vitro, although STAT3 inhibitor treatment downregulated miR-29a-5p expression, which was induced by IL-6. CONCLUSIONS Our studies showed that tumor development occurred with inflammation. The miR-29a-5p/STAT3 signaling axis could play an important role in the development of CAC, and the miR-29a-5p/STAT3 positive feedback loop may amplify the effects of inflammation, lead to decreased levels of TET and 5hmC, and eventually lead to the development of CAC.

Abstract
Neuroendocrine neoplasms (NENs) are a group of tumors originating from the neuroendocrine system. They mainly occur in the digestive system and the respiratory tract. It is well-know a strict interaction between neuroendocrine system and inflammation, which can play an important role in NEN carcinogenesis. Inflammatory mediators, which are produced by the tumor microenvironment, can favor cancer induction and progression, and can promote immune editing. On the other hand, a balanced immune system represents a relevant step in cancer prevention through the elimination of dysplastic and cancer cells. Therefore, an inflammatory response may be both pro- and anti-tumorigenic. In this review, we provide an overview concerning the complex interplay between inflammation and gastroenteropancreatic NENs, focusing on the tumorigenesis and clinical implications in these tumors.

Abstract
Background Nigeria accounts for 25% of cases of Female genital mutilation (FGM) worldwide, with increased incidence of cervical cancer. Objective This study was aimed at evaluating the relationship between FGM and HPV in a locality with high prevalence of FGM. Methods Papanicolaou test, DNA hybridization using Polymerase Chain Reaction (PCR), and flow-through hybridization was done to determine the genotypic variants of the HPV. Physical examination and questionnaires were also used to ascertain presence of FGM. Results FGM was found among 98(49%) subjects, while 23(11.5%) had one or more genotype of HPV. Majority of the cases of HPV (78.3%) occurred in FGM subjects. Seventeen Genotypes of HPV were found among subjects with FGM consisting of 11 high risk (16, 18, 31, 33, 35, 39, 52, 56, 73, 81, 82) and 6 low risk (43, 44, 6, 26, 84, 70). A correlation (p value = 0.0052 at 95% CI) was found between FGM and HPV prevalence with a positive result for post hoc analysis. Results show the first reported case of quintuple HPV infection in a single subject in Nigeria. Conclusion FGM needs to be halted as it has no known health benefit yet may increase the risk for cervical cancer.

Abstract
Context: Since there is still a great need to search for plant species with antinociceptive and anti-inflammatory activities, Diploptropis purpurea (Rich.) Amshoff (Fabaceae) is studied for the first time. Objective: This evaluates the analgesic and anti-inflammatory activities of the stem methanol extract of Diplotropis purpurea (MEDP). Material and methods: The anti-inflammatory and analgesic effects of MEDP of D. purpurea were evaluated in vivo. The antinociceptive activity was assessed in CD1 male mice were treated by oral gavage with 500 mg/kg of MEDP 30 min before submitting to acetic acid-induced abdominal writhing, hot-plate, and formalin tests. Paws oedema induced by carrageenan, histamine or serotonin were performed in male Sprague-Dawley rats to determinate the anti-inflammatory activity. Results: Oral administration of MEDP produced significant antinociceptive effects on the inflammatory phase in the formalin test [12.0 s versus 72.5 s in carboxymethyl cellulose (CMC) control group]. MEDP produced an analgesic effect in the hot-plate model, although the effect was modest compared to tramadol (40 and 60%, respectively). The oral administration of MEDP in a dose of 500 mg/kg showed maximum inhibition (75.1%) after 0.5 h in carrageenan-induced oedema, but it did not modify histamine or serotonin-induced oedemas. Discussion and conclusion: In the peripheral nociception model, acetic acid-induced abdominal writhing, the MEDP did not show a protective effect, but its analgesic effects were evident in the inflammatory phase of the formalin test and in the hot-plate model. These results show that the anti-inflammatory effect was accompanied by a reduction in the perception of painful stimuli.

Abstract
Infections and mental disorders are two of the major global disease burdens. While correlations between mental disorders and infections have been reported, the possible genetic links between them have not been assessed in large-scale studies. Moreover, the genetic basis of susceptibility to infection is largely unknown, as large-scale genome-wide association studies of susceptibility to infection have been lacking. We utilized a large Danish population-based sample (N = 65,534) linked to nationwide population-based registers to investigate the genetic architecture of susceptibility to infection (heritability estimation, polygenic risk analysis, and a genome-wide association study (GWAS)) and examined its association with mental disorders (comorbidity analysis and genetic correlation). We found strong links between having at least one psychiatric diagnosis and the occurrence of infection (P = 2.16 × 10-208, OR = 1.72). The SNP heritability of susceptibility to infection ranged from ~2 to ~7% in samples of differing psychiatric diagnosis statuses (suggesting the environment as a major contributor to susceptibility), and polygenic risk scores moderately but significantly explained infection status in an independent sample. We observed a genetic correlation of 0.496 (P = 2.17 × 10-17) between a diagnosis of infection and a psychiatric diagnosis. While our GWAS did not identify genome-wide significant associations, we found 90 suggestive (P ≤ 10-5) associations for susceptibility to infection. Our findings suggest a genetic component in susceptibility to infection and indicate that the occurrence of infections in individuals with mental illness may be in part genetically driven.

Abstract
Inflammation is a generalized, nonspecific, and beneficial host response of foreign challenge or tissue injury. However, prolonged inflammation is undesirable. It will cause loss function of involve organs, such as heat, pain redness, and swelling. Marine natural products have gained more and more attention due to their unique mechanism of anti-inflammatory action, and have considered a hotspot for anti-inflammatory drug development. Marine-derived fungi are promising sources of structurally unprecedented bioactive natural products. So far, a plethora of new secondary metabolites with anti-inflammatory activities from marine-derived fungi had been widely reported. This review covers 133 fungal metabolites described in the period of 2000 to 2018, including the structures and origins of these secondary metabolites.

Abstract
Chronic obstructive pulmonary disease (COPD) patients are at a higher risk of development of lung cancer. Frequent exacerbations of COPD trigger the disease course to chronic inflammation which likely plays a role in the pathogenesis of lung cancer. Previous studies showed influenza virus infection is one of important causes for exacerbations of COPD. Therefore, the aim of this study was to know whether influenza vaccination could reduce the incidence of lung cancer in patients with COPD.This cohort study enrolled patients (≥55 years old) with a recorded diagnosis of COPD between January 1, 2000 and December 31, 2012 by using the Taiwan Health Insurance Database. A propensity score was calculated to reduce vaccine therapy selection bias. Cox proportional hazard regressions were used to investigate the association between the influenza vaccination and lung cancer incidence after adjusting for known confounding factors. Besides, we categorized the patients into 4 groups according to vaccination status (unvaccinated, total number of vaccinations: 1, 2-3, ≥4) to evaluate the dose-dependent effect on reducing lung cancer occurrence of lung cancer in COPD patients.Our study comprised of 28,752 eligible individuals from the COPD cohort database. Among them, 51% (14,630) received influenza vaccination; the rest (49%) of the COPD patients did not receive influenza vaccination. We observed that COPD patients receiving influenza vaccination had a lower risk of lung cancer (adjusted HR = 0.40, 95% CI (0.35-0.45), P < .001). We also founded comparable protective effect in both sexes and all age groups (55-64, 65-74, ≥75) regardless of influenza seasonality. Furthermore, dose-dependent protective effect could be seen after stratifying patients according to the total number vaccinations, the adjusted HRs for lung cancer risk were 0.48 (0.40-0.54) and 0.24 (0.20-0.29) for patients who received 2 to 3 and ≥4 vaccinations during the follow-up period.This population-based cohort study demonstrated that annual influenza vaccination administration could reduce incidence of lung cancer in COPD patients.

Abstract
Chronic obstructive pulmonary disease (COPD) and lung cancer comprise the leading causes of lung disease-related mortality worldwide. Exposure to tobacco smoke is a mutual aetiology underlying the two diseases, accounting for almost 90% of cases. There is accumulating evidence supporting the role of immune dysfunction, the lung microbiome, extracellular vesicles and underlying genetic susceptibility in the development of COPD and lung cancer. Further, epigenetic factors, involving DNA methylation and microRNA expression, have been implicated in both diseases. Chronic inflammation is a key feature of COPD and could be a potential driver of lung cancer development. Using next generation technologies, further studies investigating the genomics, epigenetics and gene-environment interaction in key molecular pathways will continue to elucidate the pathogenic mechanisms underlying the development of COPD and lung cancer, and contribute to the development of novel diagnostic and prognostic tools for early intervention and personalised therapeutic strategies.

Abstract
AIM To investigate the effect of Physalis angulata leaf extract on apoptotic and proliferation of retinoblastoma cells. Despite several previous studies evidencing the anti-cancer potential of Physalis angulata; however, certain study that proves its benefits in retinoblastoma cancer cells has been limited. METHODS This study utilizes an in-vitro experimental study by applying Y79 human retinoblastoma cell line culture obtained from the American Type Culture Collection (ATCC; 10801 University Boulevard Manassas, VA 20110, USA). The cell was divided into 4 groups. Group I was the control group without the administration of Physalis angulata leaf extract. Whereas, group II, II and IV are engaged with 25, 50, and 100 µg/mL of Physalis angulata leaf extract respectively. After a 24h incubation, an examination with microtetrazolium (MTT) cell proliferation assay and Annexin V apoptosis detection was conducted. Statistical analysis was performed with the Tukey test. RESULTS Physalis angulata leaf extract improved apoptosis and significantly reduced the number of living cells in retinoblastoma cells, along with the increase in the given dose. Based on the Tukey test, a significant difference was found in the treatment group at 50 µg/mL (P=0.025) and 100 µg/mL (P=0.001) in the measurement of apoptosis. Proliferation measurements also indicated a significant decrease in the number of living cells in the 50µg/mL treatment group (P=0.004), and in the 100 µg/mL treatment group (P=0.000). Meanwhile, a dose of 25 µg/mL indicated insignificant difference in the two measurements. Improved apoptosis and decreased number of living cells occured at a dose of 100 µg/mL. Decreased number of living cells (in the measurement of proliferation) was due to the inhibited proliferation or improved apoptosis. CONCLUSION Physalis angulata leaf extract improve apoptosis in retinoblastoma cell culture, requiring further research to inhibit proliferation.

Abstract
Given the prevalence of cancer and leishmaniasis worldwide, the presence of these two pathologies in the same tissue sample may be merely fortuitous. The clinical outcome of both diseases is under the control of innate and adaptive immunity, and in both cases these progressive diseases are characterized by an impaired host Th1 response. As a consequence, the Th2 cytokine microenvironment occurring in progressive leishmaniasis may potentially promote tumor cell proliferation and vice versa. On the other hand, clinical aspects of subclinical cutaneous or visceral leishmaniasis sometimes closely resemble those observed in various neoplasms thus leading to misdiagnosis. In this review, we present recent findings on the association between leishmaniasis and malignant disorders. Our review includes HIV positive, HIV negative subjects and patients whose HIV status has not been established. Leishmaniasis mimicking a malignant disorder was confirmed and extended to unreported neoplastic disorders including squamous cell carcinoma, T-cell and B-cell lymphoma, oral and intranasal tumors and granulomas. Thus, leishmaniasis should be considered in the differential diagnosis and course of various cancers in Leishmania endemic areas or in patients with travel history to these areas. We also listed recent reports showing that Leishmania can promote cancer development in immunocompromised as well as in immunocompetent patients. The potential mechanisms supporting this promoting effect are discussed.

Abstract
Background: Pleurodesis is often used to prevent the re-accumulation of a malignant
pleural effusion (MPE). Intrapleural urokinase (IPUK) therapy facilitates
lung re-expansion for patients with loculated MPE or a trapped lung that
allows subsequent pleurodesis. MPE management has been traditionally
regarded as a symptomatic treatment. We tried to evaluate their impact on
patient survival. Methods: There were 314 consecutive patients with symptomatic MPE that underwent
minocycline pleurodesis with (n = 109) and without
(n = 205) the antecedent IPUK therapy between September
2005 and August 2015, who were recruited for the pleurodesis outcome and
survival analysis. Results: The rate of successful pleurodesis was similar between the simple pleurodesis
group and the IPUK therapy group followed by the pleurodesis group (69.0%
versus 70.5%; p = 0.804). The patients
who succeeded pleurodesis had a longer survival rate than those who failed
in either the simple pleurodesis group (median, 414 versus
100 days; p < 0.001) or the IPUK therapy followed by
pleurodesis group (259 versus 102 days; p
< 0.001). The survival differences remained when the lung and breast
cancer patients were studied separately. Conclusion: Successful pleurodesis translated into a better survival rate that promotes
performing pleurodesis on lung re-expansion. The apparent shorter survival
of the patients with loculated MPE or trapped lung, and those that did not
respond to the IPUK therapy, lowered the probability of the survival benefit
through the simple physical barrier by the fibrin formation to prevent the
tumor spreading. The successfully induced inflammatory response by
minocycline is supposed to prohibit the tumor invasion and metastasis.
Further studies are warranted to clarify the mechanism and provide
opportunities to develop novel therapeutic strategies.

Abstract
Chronic inflammation plays a prominent role in cancer initiation and development. On the other hand, the Inflammation can be established by a number of factors such as viral infections. Parvovirus B19 (B19V) is a pathogen with widespread infection, which infects bone marrow erythroid progenitor cells. It has been shown that B19V can also enter human bone marrow mesenchymal stem cells (BM-MSCs). In this study, we hypothesized that BM-MSCs as the main cellular component of bone marrow niche may be induced to secret pro-inflammatory cytokines after B19V infection. BM-MSCs were cultured up to passage 3. The cells were then subjected to nucleofection to transfer a plasmid containing B19V genome. After 36 h, total RNA was extracted and the expression levels of IL-1β, IL-6, TNF-α and NF-κB genes were examined using qRT-PCR. Data analysis showed the significant increase in expression levels of all studied genes in the B19V-transfected cells (P < 0.05). Although further researches are required, our findings for the first time suggest the importance of B19V infection to establish an inflammatory microenvironment in the bone marrow and its involvement in inflammation-related diseases. Finally, based on our results, molecular assay to diagnose B19V infection of BM-MSCs prior to stem cell therapy is strongly recommended.

Abstract
Molecular mechanisms associated with inflammation-promoted tumorigenesis have become an important topic in cancer research. Various abnormal epigenetic changes, including DNA methylation, histone modification, chromatin remodeling, and noncoding RNA regulation, occur during the transformation of chronic inflammation into colorectal cancer (CRC). These changes not only accelerate transformation but also lead to cancer progression and metastasis by activating carcinogenic signaling pathways. The NF-κB and STAT3 signaling pathways play a particularly important role in the transformation of inflammation into CRC, and both are critical to cellular signal transduction and constantly activated in cancer by various abnormal changes including epigenetics. The NF-κB and STAT3 signals contribute to the microenvironment for tumorigenesis through secretion of a large number of pro-inflammatory cytokines and their crosstalk in the nucleus makes it even more difficult to treat CRC. Compared with gene mutation that is irreversible, epigenetic inheritance is reversible or can be altered by the intervention. Therefore, understanding the role of epigenetic inheritance in the inflammation-cancer transformation may elucidate the pathogenesis of CRC and promote the development of innovative drugs targeting transformation to prevent and treat this malignancy. This review summarizes the literature on the roles of epigenetic mechanisms in the occurrence and development of inflammation-induced CRC. Exploring the role of epigenetics in the transformation of inflammation into CRC may help stimulate futures studies on the role of molecular therapy in CRC.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Like other concepts in traditional Chinese medical theory, "body fire", a concept that has already been well-known and widely used in describing the symptoms and the treatment of corresponding diseases, is, however, still under suspicions in the western medicine due to its vague essence and symptoms. Presently, Huang-Lian-Jie-Du-Tang (HLJDT), a typical popular TCM formula in cleansing the "body fire", is studied as a probe by a systems pharmacology method we produced, with purpose to explore the mechanisms of the potion, as well as to interpret the essence of "body fire" disease. METHODS The systematic process includes a pharmacokinetics prescreening, pharmacodynamics targets and pathways identification, and candidate-target-pathway network construction. RESULTS Through this method, 145 chemicals and 91 proteins are identified as active ingredients and "body fire"-related targets. And we find that the mechanism of HLJDT prescription for cleansing "body fire" lies in three, i.e., anti-OS/NS, anti-inflammation and anti-infection function modules, which are mainly executed through four, i.e., PI3K-AKT, MAPK, VEGF as well as Calcium signaling pathways. CONCLUSIONS Accordingly, the essence of "body fire" is a gradual process which is an integration of OS/NS, inflammation and infection. This work, we hope, may not only offer a systemic methodology for exploring and elucidating TCM concepts from a multi-scale perspective, but also provide an efficient way for herbal drug discovery.

Abstract
Background and Aims: Synbiotics found to be beneficial in breast cancer survivors (BCSs) through its antioxidant properties. The aim of this study was to assess the effects of synbiotic supplementation on edema volume and some oxidative markers among obese and overweight patients with BCRL.Method: This randomized double-blind, placebo-controlled trial was conducted on 88 overweight and obese BCSs aged 18-65 years. All the subjects were given a specified low-calorie diet (LCD) and were randomly assigned into two groups to intake 109 CFU/day synbiotic supplement (n = 44) or placebo (n = 44) for 10 wk. Edema volume and serum total antioxidant capacity (TAC), malondialdehyde (MDA), glutathione peroxidase (GPx), and superoxide dismutase (SOD) concentration were measured at baseline and after the 10-wk intervention.Results: Ten-wk supplementation with synbiotics leads to a significant reduction in serum MDA levels (P = 0.001) and an increase in serum SOD concentration (P = 0.007) compared to placebo. No significant changes were observed in serum GPx, TAC, and edema volume between groups.Conclusion: Our findings reveal that 10-wk synbiotic supplementation along with a LCD program-reduced serum MDA levels and elevate the activity of SOD in overweight and obese patients with BCRL. However, its effect on serum GPx, TAC, and edema volume was not significant.

Abstract
We previously reported that cystatin B (CSTB) is a progression marker of human ovarian cancer (OC); however, the regulatory mechanism of CSTB and its function in OC remain unclear. The present study aimed to explore the mechanism underlying transforming growth factor-β (TGF‑β) 1‑mediated CSTB regulation, and to examine the function of CSTB on OC cell proliferation and apoptosis. Using the online program, miRWalk, a microRNA (miR)‑143‑3p was detected, which contains a homologous sequence of the potential binding site to the 3'‑untranslated region (3'‑UTR) of CSTB. A dual‑luciferase reporter assay confirmed the interaction between miR‑143‑3p and CSTB 3'‑UTR. Treating OC cells with miR‑143‑3p mimics or inhibitors resulted in a decrease or an increase of CSTB expression at mRNA and protein levels, respectively. Additionally, CSTB was significantly overexpressed, whereas miR‑143‑3p was downregulated in human OC tissues compared with normal ovarian tissues. A negative correlation between miR‑143‑3p and CSTB mRNA expression was observed in ovarian malignant tumors. The levels of primary and mature miR‑143‑3p expression were upregulated in OC cells after TGF‑β1 treatment; the action of TGF‑β1 was abolished in the presence of an inhibitor of TGF‑β type I receptor. These results indicated an axis between TGF‑β, miR‑143‑3p and CSTB in OC cells. Furthermore, high levels of CSTB expression were associated with the poor overall survival of patients with OC. Knockdown of CSTB resulted in a decrease in OC cell proliferation and arrested cells in G2/M phase. In addition, suppression of CSTB induced cell apoptosis. In conclusion, CSTB was overexpressed and miR‑143‑3p was downregulated in ovarian malignant tumors. Mature miR‑143‑3p directly bound CSTB 3'‑UTR, leading to a decrease in CSTB expression in OC cells, which was regulated by TGF‑β1. Our findings suggest the potential therapeutic application of targeting the TGF‑β/miR‑143‑3p/CSTB axis for treating patients with OC.

Tian L, Wang ZY, Hao J, Zhang XY. miR-505 acts as a tumor suppressor in gastric cancer progression through targeting HMGB1. J Cell Biochem 2019; 120:8044-8052. [PMID: 30525214 DOI: 10.1002/jcb.28082] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2018] [Accepted: 10/22/2018] [Indexed: 01/24/2023]
Abstract
Gastric cancer (GC) is a frequent type of malignant tumor worldwide. GC metastasis results in the majority of clinical treatment failures. MicroRNAs (miRNA) are identified to exhibit crucial roles in GC. Our current study aimed to explore the biological roles of miR-505 in GC progression. It was observed that miR-505 was robustly decreased in GC cells compared with human normal gastric epithelial GES-1 cells. Overexpression of miR-505 was able to repress GC progression in AGS and BGC-823 cells. In addition, high-mobility group box 1 (HMGB1) has been identified as a crucial oncogene in several cancer types. By carrying out bioinformatics analysis, HMGB1 was predicted as a direct target of miR-505. Meanwhile, HMGB1 was found to be significantly increased in GC cells and it was confirmed in our study that miR-505 can directly target HMGB1 in vitro. miR-505 mimics can inhibit HMGB1 messenger RNA and protein expression dramatically. Subsequently, knockdown of HMGB1 can inhibit GC cell proliferation, colony formation, and induce cell apoptosis. Furthermore, HMGB1 silence suppressed GC cell migration and invasion greatly in vitro. Finally, it was validated that miR-505 can inhibit GC progression by targeting HMGB1 in vivo. Taken these together, it was indicated that miR-505/HMGB1 axis was involved in the development of GC. miR-505 can serve as a potential prognostic indicator in GC therapy.

Abstract
Interleukin-21 (IL-21) is a cytokine with potent regulatory effects on different immune cells. Recently, IL-21 has been contemplated for use in the treatment of cancers. However, the molecular mechanisms regulating human IL-21 gene expression has not yet been described. In this study, we initially studied the promoter region and identified the transcription start site. We thereafter described the essential region upstream of the transcription start site and showed the in vivo binding of NFATc2 and SP1 transcription factors to this region, in addition to their positive role in IL-21 expression. We also studied the role of microRNAs (miRNAs) in regulating IL-21 expression. We, thus, established the miRNA profile of CD4+CD45RO+ versus CD4+CD45RA+ isolated from healthy volunteers and identified a signature composed of 12 differentially expressed miRNAs. We showed that miR-302c is able to negatively regulate IL-21 expression by binding directly to its target site in the 3'-untranslated region. Moreover, after using fresh human CD4-positive T cells, we observed the high acetylation level of histone H4, an observation well in line with the already described high expression of IL-21 in CD4+CD45RO+ versus CD4+CD45RA+ T cells. Altogether, our data identified different molecular mechanisms regulating IL-21 expression.

Abstract
Breast cancer is recognized as the most common type of cancer among women with a high rate of mortality all over the world. Over the past years, growing attention has been regarded to realize more about the mechanisms underlying the disease process. It is revealed that the progression of breast cancer may be strongly linked to chronic inflammation owing to the role of inflammatory factors in genetic instability and subsequent cancer predisposition. Although the association between breast cancer and inflammatory pathways has been well-defined now, only recent evidence pointed towards the inflammation-related microRNAs (miRNAs) as potential biomarkers and therapeutic targets involved in the crosstalk of multiple pathways during breast cancer development. Moreover, the practical interactions between these miRNAs and inflammatory factors are also a little characterized. In this review, we intended to describe the effects of predominant inflammatory pathways such as cytokines, phosphoinositide 3-kinase/protein kinase B, and nuclear factor kappa B in association with tumor promoting and tumor suppressing miRNAs on breast cancer progression. Providing new studies in the field of combining biomarkers for early diagnosis, prognosis, and monitoring breast cancer are very important. Notably, understanding the underlying mechanisms of miRNAs as a possible link between inflammation and tumorigenesis may offer a novel insight for combating this epidemic.

Abstract
BACKGROUND The long noncoding RNA (lncRNA) colon cancer-associated transcript-1 (CCAT1) has been reported to play a vital role in the development of cancer. Although the link between inflammation and cancer initiation is well established, whether CCAT1 is involved in inflammation and promotes inflammatory bowel disease (IBD) malignancy remains undetermined. We aimed to investigate the expression of CCAT1 in IBD and the effect of CCAT1 overexpression on intestinal epithelial barrier function. METHODS The relationship between CCAT1 and the inflammation-related pathway was analyzed in both colorectal cancer (CRC) and IBD patients. Gene expression was detected by real-time polymerase chain reaction and Western blot. Transepithelial electrical resistance (TEER) and FD-4 flux measurement were used to test the effect of CCAT1 and miR-185-3p on intestinal epithelial barrier function. Luciferase assay was performed to validate the target site of miR-185-3p on 3'-UTR of MLCK mRNA. RESULTS Gene set enrichment analysis revealed that several inflammation-related genes were enriched in the CCAT1 high-expressed group of CRC patients. The relationship between CCAT1 and inflammation activation in IBD patients was further confirmed. CCAT1 expression positively correlated with MLCK, which acts as a protein kinase to phosphorylate myosin light chain and induces tight junction protein distribution, whereas it was negatively correlated with miR-185-3p in IBD tissues. We also determined that CCAT1 overexpression increased Caco-2 monolayer permeability and upregulated MLCK. Furthermore, CCAT1-induced MLCK overexpression and IBD disease progression were significantly attenuated by miR-185-3p. CONCLUSIONS The CCAT1/miR-185-3p/MLCK signaling pathway is strongly activated to destroy barrier function and promotes the pathogenesis of IBD.

Abstract
Mitochondrial ribosomal protein S23 (MRPS23), encoded by a nuclear gene, is a participant in the translation of mitochondrial proteins. Recently, MRPS23 has been reported to be overexpressed in many types of cancers and have a close association with cancer progression. However, the specific roles of MRPS23 in osteosarcoma (OS) remain unknown. In this study, we investigated the expression pattern and biological functions of MRPS23 in OS cells. Our results demonstrated that MRPS23 was up-regulated in OS tissues and cell lines. Down-regulation of MRPS23 significantly inhibited OS cell proliferation and invasion induced by lipopolysaccharide (LPS) in vitro. Furthermore, the in vivo experiments showed that MRPS23 down-regulation markedly suppressed OS cell growth and metastasis induced by LPS. Mechanistically, down-regulation of MRPS23 inhibited the activity of NF-κB signaling pathway in OS cells. In conclusion, these findings indicated that MRPS23 may be a potential therapeutic target for OS treatment. Mitochondrial ribosomal protein S23 (MRPS23), encoded by a nuclear gene, is a participant in the translation of mitochondrial proteins.![]()

Abstract
Chronic inflammation mediates an extraordinarily wide range of diseases. Recent progress in understanding intracellular inflammasome assembly, priming, activation, cytokine signaling, and interactions with mitochondrial reactive oxygen species, lysosome disruption, cell death, and prion-like polymerization and spread of inflammasomes among cells, has potentially profound implications for dose-response modeling. This article discusses mechanisms of exposure concentration and duration thresholds for NOD-like receptor protein 3 (NLRP3)-mediated inflammatory responses and develops a simple biomathematical model of the onset of exposure-related tissue-level chronic inflammation and resulting disease risks, focusing on respirable crystalline silica (RCS) and lung cancer risk as an example. An inflammation-mediated 2-stage clonal expansion model of RCS-induced lung cancer is proposed that explains why relatively low estimated concentrations of RCS (eg, <1 mg/m3) do not increase lung cancer risk and why even high occupational concentrations increase risk only modestly (typically relative risk <2). The model of chronic inflammation implies a dose-response threshold for excess cancer risk, in contrast to traditional linear-no-threshold assumptions. If this implication is correct, then concentrations of crystalline silica (or amphibole asbestos fibers, or other environmental challenges that act via the NLRP3 inflammasome) below the threshold do not cause chronic inflammation and resulting elevated risks of inflammation-mediated diseases.

Abstract
Previous studies demonstrated that estrogen receptor β (ERβ) signaling alleviates systemic inflammation in animal models, and suggested that ERβ-selective agonists may deactivate microglia and suppress T cell activity via downregulation of nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB). In the present study, the role of ERβ in lipopolysaccharide (LPS)-induced inflammation and association with NF-κB activity were investigated in PC-3 and DU145 prostate cancer cell lines. Cells were treated with LPS to induce inflammation, and ELISA was performed to determine the expression levels of inflammatory cytokines, including tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein 1 (MCP-1), interleukin (IL)-1β and IL-6. MTT and Transwell assays, and Annexin V/propidium iodide staining were conducted to measure cell viability, apoptosis and migration, respectively. Protein expression was determined via western blot analysis. LPS-induced inflammation resulted in elevated expression levels of TNF-α, IL-1β, MCP-1 and IL-6 compared with controls. ERβ overexpression significantly inhibited the LPS-induced production of TNF-α, IL-1β, MCP-1 and IL-6. In addition, the results indicated that ERβ suppressed viability and migration, and induced apoptosis in prostate cancer cells, which was further demonstrated by altered expression of proliferating cell nuclear antigen, B-cell lymphoma 2-associated X protein, caspase-3, E-cadherin and matrix metalloproteinase-2. These effects were reversed by treatment with the ERβ antagonist PHTPP or ERβ-specific short interfering RNA. ERβ overexpression reduced the expression levels of p65 and phosphorylated NF-κB inhibitor α (IκBα), but not total IκBα expression in LPS-treated cells. In conclusion, ERβ suppressed the viability and migration of the PC-3 and DU145 prostate cancer cell lines and induced apoptosis. Furthermore, it reduced inflammation and suppressed the activation of the NF-κB pathway, suggesting that ERβ may serve roles as an anti-inflammatory and anticancer agent in prostate cancer.

Abstract
Under pathological conditions like inflammation, ischemia or in solid tumors, parameters of the microenvironment like local oxygenation and extracellular pH show marked changes when compared to healthy tissue. The altered microenvironment affects cellular phenotype of omnipresent fibroblasts and immune cells. Recently, the impact of the microenvironment on the expression patterns of microRNAs, small non-coding RNAs that regulate gene expression on a post-transcriptional level, was discussed. Therefore, microRNAs might be the link between altered microenvironmental parameters and changes in cellular phenotype. In this study, the effect of hypoxia-induced extracellular acidosis (24 h pH 6.6) on microRNA expression in fibroblasts and macrophages was analyzed. MicroRNAs in rat fibroblasts (NRK-49F) were examined with the miScript miRNA PCR Array and changes in the expression validated by TaqMan qPCR. Subsequently, the identified microRNAs were analyzed in RAW 264.7 mouse macrophages. Nine out of 84 tested microRNAs were found to be acidosis-regulated in fibroblasts by miRNA PCR array, most of them up-regulated. Of those, the pH dependency could be validated by TaqMan qPCR for five of these nine microRNAs. When comparing these microRNAs in terms of their expression in macrophages, profound differences were observed. Thus, acidosis-induced alterations in the expression of microRNAs seem to be cell-type specific. Only the up-regulation of the miR-133b by low pH was seen in all normal cells, but not in tumor cells. As the identified microRNAs are involved in the regulation of proliferation, cell death and migration (amongst others), acidosis-induced changes in their expression might affect cellular behavior of fibroblasts and macrophages under pathological conditions. For instance the proto-oncogene c-Jun, which is a target of the miR-133b, was shown to be acidosis-regulated. Acidosis could regulate the biological behavior via miRNA-133b and c-Jun.

Abstract
Purpose In the present study, we aimed to investigate the effects of tomato powder (TP) on glucose and lipid metabolism, as well as oxidative stress and the NF-κB, mTOR, and Nrf2 pathways during the aging process in healthy rats. Methods and Results Male Wistar rats were randomly assigned to four groups as follows: (i) Control group 1 (n=15, 3-week old): rats were fed standard diet for 7 weeks; (ii) TP group 1 (n=15, 3-week old): rats were fed standard diet supplemented with TP for 7 weeks; (iii) Control group 2 (n=15, 8-week old): rats were fed standard diet for 69 weeks; and (iv) TP group 2 (8-week old): rats were fed standard diet supplemented with TP for 69 weeks. TP supplementation significantly reduced the hyperglycemia, hypertriglyceridemia, and hypercholesterolemia and improved liver function and kidney function in 77-week old rats compared with the control animals (P < 0.05). In addition, TP significantly decreased the serum and liver MDA levels (P < 0.003 and P < 0.001, respectively) while increasing the activities of liver SOD (P < 0.001), CAT (P < 0.008), and GPx (P < 0.01) compared with the control groups in both 10-week-old and 77-week-old rats (P < 0.05). Age-related increases in phosphorylation of NF-κBp65, mTOR, 4E-BP1, and P70S6K were observed in livers of 77-week-old rats compared to those of 10-week-old rats (P < 0.001). TP supplementation decreased the expression of NF-κBp65 and activation of mTOR, 4E-BP1, and P70S6K in livers of 77-week-old rats compared to the control animals. Moreover, TP supplementation significantly elevated Nrf2 expression in livers of both 10-week-old and 77-week-old rats (P < 0.05). Conclusion TP ameliorates age-associated inflammation and oxidative stress through the inhibition of NF-κBp65, mTOR pathways, and Nrf2 activation may explain the observed improvement in glucose and lipid metabolism as well as the improved liver and kidney functions.
