Abstract Background: Colorectal cancer is a major global health concern, exacerbated by tumor necrosis factor-alpha(TNF-α) and its role in inflammation, with the effects of Mitotic Arrest Deficient 2 Like 2 (MAD2L2) in this context still unclear. Methods: The colorectal carcinoma cell lines HCT116 and SW620 were exposed to TNF-α for a period of 24 h to instigate an inflammatory response. Subsequent assessments were conducted to measure the expression of inflammatory cytokines, the activity within the p38 mitogen-activated protein kinase (p38 MAPK) and Phosphoinositide 3-Kinase/AKT Serine/Threonine Kinase pathway (PI3K/AKT) signaling cascades. Transcriptome sequencing and subsequent integrative analysis… More >

Abstract Triple Negative Breast Cancer (TNBC) immunotherapy has recently shown promising approach. However, some TNBC patients presented with resistance. One of the reasons was attributed to the excessive release of cytokines at the tumor microenvironment (TME) such as Tumor necrosis factor alpha (TNF-α) and Interleukin-10 (IL-10). Fine regulation of these cytokines’ levels via non-coding RNAs (ncRNAs) might alleviate the immune quiescent nature of TME at TNBC tumors. However, the extrapolation of ncRNAs as therapeutic tools is highly challenging. Therefore, disentanglement the nature for the isolation of natural compounds that could modulate the ncRNAs and their respective… More >

Abstract Background: Obesity and dyslipidemia due to estrogen deficiency are among the important health problems in menopausal women. Increasing evidence reports the anti-obesity and anti-hyperlipidemic properties of tea polyphenols. However, the effect of white tea (WT) with high polyphenol content on overweight and lipid profile is uncertain. Here, we aimed to examine the effects of long-term WT consumption on serum leptin, tumor necrosis factor-alpha (TNF-α) and uncoupling protein 1 (UCP1) mRNA gene expression in ovariectomized (OVX) rats. Methods: Adult rats were divided into four groups (n = 8): (i) sham, (ii) OVX, (iii) WT and (iv)… More >

Abstract Chronic hepatitis B (CHB) is classified into five phases based on virus-host interactions: immune tolerance, immune clearance, inactive carrier state, reactive phase and occult hepatitis B infection (OBI). OBI is an uncommon asymptomatic phase of CHB that can be reactivated when the immune system is compromised, occasionally giving rise to severe liver disease. Host immune factors play essential roles in all phases of the CHB infection. Cytokines may alter infection course, influencing the propensity for and the progression of CHB and thus warrant study. Three clinical groups were studied: 48 healthy individuals (HI), 28 patients… More >

Abstract Nonsteroidal anti-inflammatory drugs have a number of side effects. However, some medicinal herbs have anti-inflammatory properties with few side effects. This study aimed to determine the effect of the aqueous extract of Gongronema latifolium (AEGL) leaves on the level of tumor necrosis factor-α (TNF-α), transforming growth factor-β (TGF-β), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in rabbits. Enzyme-linked immunosorbent assay (ELISA) was performed to determine the effect of the AEGL on the activities of pro-inflammatory cytokine (TNFα), and regulatory cytokine (TGF-β) in rabbits. Also, a colorimetric method was performed to evaluate the levels of AST and More >

Abstract Background and Objective: LTB4 has been shown to be involved in rheumatoid arthritis (RA) pathogenesis. The effect of Dioscin(Dio) on the LTB4 pathway of RA have not been reported yet. This study aimed at further exploring whether Dioscin’s effects on TNF-α induced collagen-induced arthritis (CIA) rat fibroblast-like synoviocytes (FLS) connected with the LTB4 and its receptor pathway. Materials & Methods: In this experiment, control group, TNF-α group, and different concentrations of Dioscin groups were established. Cell viability was evaluated using MTT assay. The levels of LTB4 in the samples of above groups were measured using ELISA.… More >

Abstract Periodontitis, as a chronic inflammatory disease, remains unsolved, and the pathogenesis of this disease has not been fully elucidated. In this study, the effect of miR-4262 was investigated in tumor necrosis factor-α (TNF-α) induced human periodontal stem cells (hPDLSCs) for the first time. The gene expression involved in this study was determined using polymerase chain reaction (PCR), the expressions of relevant proteins were determined by western blot analysis, and the levels of IL-1β, IL-6, and MCP-1 were estimated by enzyme-linked immunosorbent assay (ELISA) assay. The luciferase reporter assay was performed for verification of the target More >

Abstract Background and aims: Chronic hepatic inflammation is an important pathogenic mediator of nonalcoholic fatty liver disease (NAFLD) that contributes to disease severity. It is commonly suggested that autophagy dysfunction may be an underlying cause of nonalcoholic fatty liver disease. However, the exact role of autophagy in lipid metabolism remains controversial. There has been a growing interest in the role of folate supplementation for the treatment and/or prevention of NAFLD. We aimed in this study to investigate the effects of different doses of folate supplementation on several immune markers and autophagy trying to explore the complex… More >

Abstract Introduction: Increased levels of pro- and anti-inflammatory cytokines were observed in various segments of histologically-intact small intestine in animal models of acute and chronic colitis. Whether these cytokines are produced locally or spread from the inflamed colon is not known. In addition, the role of gut innervation in this upregulation is not fully understood. Aims: To examine whether cytokines are produced de novo in the small intestine in two rat models of colitis; and to investigate the role of capsaicin-sensitive primary afferents in the synthesis of these inflammatory cytokines. Methods: Colitis was induced by rectal… More >

Abstract The aim of this study was to evaluate the effects of the LL-37, HNP-1 and HBD2/3 peptides on cytokine and MMP production in human polymorphonuclear cells, mononuclear cells and chondrocytes. The levels of cytokines in supernatants from mononuclear and polymorphonuclear cell cultures were measured with a cytometric bead array by flow cytometry. Likewise, the levels of metalloproteinase/MMP-1, 3, and 13 were measured in supernatants from chondrocyte cultures using an ELISA. The expression of RANKL on lymphocytes was analyzed by flow cytometry. We observed increased levels of TNF-α, IL-6 and IL-10 in mononuclear and polymorphonuclear cell… More >
