Abstract
BACKGROUND Tumor Necrosis Factor-Alpha (TNF-α) is a proinflammatory cytokine that plays a role in inflammation, which is one of the hallmarks of cancer, and its polymorphic variants have been associated with disease risk in many cancers in the literature. The aim of this study was to investigate four different polymorphic variants, differential methylation and expression status of the TNF-α gene and to determine the associations between these variants and disease risk, and to evaluate the relationship between the results and clinical parameters. We purposed to investigate the genetic and epigenetic alterations of the TNF-α gene in larynx cancer (LC). MATERIAL AND METHODS After isolation of DNA/RNA from whole blood, tumor and normal tissue, polymorphic variant alleles differrential expression and methylation levels were analyzed by RFLP, semiquantitative RT-PCR, and restriction enzyme digestion, respectively. TNF-α expression and methylation levels were calculated using BIO1D software. The frequencies of the variants c.-238 G>A (rs361525), c.-857 C>T (rs1799724), c.-863 C>A (rs1800630), and c.-1031 T > C (rs1799964) in the promoter region of TNF-α in LC Turkish patients and healthy individuals were examined using the De-Finetti case-control program. Haplotype frequencies and linkage disequilibrium were analyzed using the SNPStats program. RESULTS The frequency of genotype c.-1031 T > C was significantly lower in patients than in healthy individuals [TT vs TC: OR (%95CI) = 7.00 (1.75-27.93), p = 0.003, χ2 = 8.76]. The heterozygous variant of - 857 was associated with recurrence [T vs G: OR (%95CI) = 0.15 (0.02-0.95), p = 0.02, χ2 = 4.86]. For c.-238 G>A, c.-857 C>T, and c.-863 C>A, there was no statistically significant difference between the patient and healthy group in terms of disease risk. A significant association was found between c.-1031 T > C and disease risk of LC. Decreased expression was detected in 46% (23/50) and increased expression in 54% (27/50) of tumor tissue samples compared to the matched normal tissues of patients. Methylation-related loss of expression was detected in 53.3% (16/30) of patients. CONCLUSION Our study is the first investigating four different polymorphic regions of the TNF-α promoter region and the expression/methylation status of TNF-α in the same LC patient and healthy cohort. According to our results, the c.-1031 T > C variant was reported to be significantly associated with a reduced risk of LC. In addition, the TNF-α variant c. -857 C>T suggests that it may be a potential biomarker for predicting the recurrence of LC. An association between c. -857 C>T variant and methylation-based expression status was observed.

Abstract
OBJECTIVE To evaluate the association of gene polymorphisms of the SNP of TNF-α gene -238G>A and IL-18 gene-607C>A with the development of hepatocellular carcinoma among Egyptian patients. METHODS One hundred and fifty patients were allocated to this study; eighty patients with hepatocellular carcinoma (Group A), seventy cancer-free HCV age, and sex-matched patients (Group B). We analyzed two Single nucleotide polymorphisms (SNPs) (TNF-α-238G>A and IL-18-607C>A) by real-time polymerase chain reaction using sequence-specific primers (PCR-SSP). RESULTS Significant higher risk of HCC was associated with genotype IL-18-607AA (p <0.001), OR: 5(2.188-11.47), allele IL-18 -607⁄A (P=0.001), OR: 2.1(1.32-3.3). A significant association was found between the size of HFL in the HCC group and different genotypes of IL18 genes (P=0.013) where 62.5% of patients with tumor size >5 cm carried the risky (AA) genotype on the other hand the SNP of TNF-α gene -238G>A showed no statistically significant association between the two groups. CONCLUSION The SNP -607C>A in the IL18 gene was associated with increased HCC risk in Egyptian patients suggesting its use as a potential diagnostic non-invasive tool that allows to identify a new group of HCC patients at an earlier stage.<br />.

Abstract
BACKGROUND Research focusing on the relationship between five types of tumor necrosis factor-alpha (TNF-α) SNPs and the risk of hepatocellular carcinoma (HCC) were still controversial. Hereby, we performed a meta-analysis to determine the association between TNF-α promoter SNPs: -1031 T/C, - 863 C/A, - 857 C/T, - 308 G/A, and - 238 G/A with HCC risk. METHODS We interrogated articles from journal database: PubMed, Pro-Quest, EBSCO, Science Direct, and Springer to determine the relationship between five types of SNPs in TNF-α gene with HCC risk. RevMan 5.3 software was used for analysis in fixed/random effect models. RESULTS This meta-analysis included 23 potential articles from 2004 to 2018 with 3237 HCC cases and 4843 controls. We found that SNP - 863 C/A were associated with a significantly increased HCC risk (A vs C, OR = 1.31, 95% CI = 1.03-1.67). Similar results were obtained in - 857 C/T (TT/CT vs CC, OR = 1.31, 95% CI = 1.06-1.62), - 308 G/A (AA vs GG, OR = 3.14, 95% CI = 2.06-4.79), and - 238 G/A (AA vs GG, OR = 3.87, 95% CI = 1.32-11.34). While no associations were observed between SNP TNF-α - 1031 T/C and HCC risk. CONCLUSIONS The present meta-analysis showed that TNFα SNPs -863C/A, - 857 C/T, - 308 G/A, and - 238 G/A were associated with the risk of HCC.

Abstract
Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Studies have shown that the tumour necrosis factor alpha (TNF-α) plays an important role in the development of HCC; however, the association between genetic variations of TNF-α and HCC is not yet fully understood. To evaluate the correlation of TNF-α polymorphisms with HCC, we randomly selected 327 HCC patients and 432 healthy controls, all these subjects reported Han nationality. Genotyping of four TNF-α SNPs (rs1799724, rs1800629, rs1799964 and rs1800610) was performed using the matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS) method. Distributions of rs1799964 genotypes and rs1800610 alleles were found to be significantly different between cases and controls (p = .011, p = .001). The recessive model of rs1799964 significantly increased HCC risk (p = .0015), while the dominant and over-dominant models of rs1800610 significantly reduced HCC risk (p = .0096, p = .014). Haplotype analysis of the four TNF-α SNPs revealed that the TGTA haplotype was associated with a reduced HCC risk (p = .0033, OR = 0.53), while the TGTG haplotype was associated with an increased HCC risk (p = .0032, OR = 9.69). These findings indicated that specific TNF-α polymorphisms may be associated with the susceptibility to HCC.

Abstract
Our aim was to evaluate the association of genetic polymorphisms of immunoregulatory molecules with susceptibility to hepatocellular carcinoma (HCC). The polymorphisms in CTLA-4 (-318 T/C, CT60 G/A), TNF (-238 G/A, -308 G/A) and IL10 (-592 C/A, -819 C/T) were genotyped by PCR and DNA sequencing. The functional relevance of the polymorphisms was examined by ELISAs, in vitro lymphocyte proliferation assay and cytotoxic assay. The CTLA-4 -318 TC/TT, CTLA-4 CT60 GG, IL10 -592 CA and -819 CT/TT variants, CTLA-4 -318 T and IL 10 -819 T alleles were positively associated with HCC risk (P < .05). While TNF -238 AA variant, TNF -238 A allele were associated with decreased risk of HCC (P < .05). Furthermore, combinations of CTLA-4 -318 TC/TT and TNF -238 GG/GA; CTLA-4 -318 TC/TT and IL 10 -819 CC; CTLA-4 -318 CC and IL 10 -819 CT/TT in patients with HCC were statistically significant (P < .05). Peripheral blood mononuclear cells (PBMCs) carrying -318 TC/TT genotypes exhibited significantly lower proliferation rates, decreased IL-2, IL-4 levels, fewer cytolytic activities and elevated TGF-β levels. For IL 10 -819 C/T, the CC genotype was significantly associated with higher proliferation rate, decreased TGF-β, IL-10 levels and higher cytolytic activities (P < .05). For TNF -238 G/A, the AA genotype only had association with serum IL-2, IL-4 (P < .05). In addition, we also found that CTLA-4 -318 T/C, IL-10 -819 T/C variants, combinations of CTLA-4 -318 CC with IL 10 -819 CT or TT, CTLA-4 -318 TC or TT with IL 10 -819 CT or TT were associated with the severity of HCC. These findings suggest that CTLA-4 -318 TC/TT and IL 10 -819 CT/TT could promote the pathogenesis of HCC, which might be related with down-regulation of Th1/Th2-type cytokines and/or up-regulation of Th3-type cytokines.

Abstract
Background and Aims: Accumulated evidence has shown that chronic liver inflammation is one of the main risks of hepatocellular carcinoma (HCC), and E167K variant of the transmembrane 6 superfamily member 2 (TM6SF2) plays an important role in the progression of chronic liver diseases and HCC. The aim of this study was to explore effects of the TM6SF2 E167K variant on expression of the inflammatory cytokines TNF-α, IL-2, IL-6 and IL-8 in the HCC cell line HEPA 1-6. Methods: HEPA 1-6 cells were infected with lentivirus containing either the TM6SF2 E167K variant or TM6SF2 wild-type, or control plasmids. Quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting were conducted to analyze the expression of the inflammatory cytokines TNF-α, IL-2, IL-6 and IL-8. A t-test was used for statistical analysis. Results: Compared with the control group and TM6SF2 overexpression group, the relative expression of IL-2 and IL-6 mRNAs were significantly elevated in the TM6SF2 E167K overexpression group (p < 0.05). The relative mRNA expression of IL-8 in the TM6SF2 and TM6SF2 E167K overexpression groups were increased compared to the control group (p < 0.05). No obvious differences were observed for the expression of TNF-α in each group. The expression of TNF-α, IL-2, IL-6 and IL-8 that was tested by western blotting showed the same trends as the qRT-PCR results. Conclusions: In conclusion, the E167K variant of the TM6SF2 gene could promote the expression of inflammatory cytokines IL-2 and IL-6 in HEPA 1-6 cells, suggesting that the TM6SF2 E167K variant may accelerate the progression of HCC.

Abstract
PURPOSE Tumor necrosis factor-α has been suggested to play a crucial role in the development andprogression of hepatocellular carcinoma (HCC). Previous reports have indicated that rs361525 and rs1800629 might be risk factors for various cancers. Increasing studies have been conducted on the association of these two SNPs with HCC risk but the results remain inconclusive. METHODS In order to detect association between TNF- α and HCC, a meta-analysis was performed. Five studies with 541 cases and 795 controls were used for rs361525, while six studies including 925 cases and 1307 controls were collected for investigating rs1800629. The grouping of countries from data were obtained was done by Principal Coordinate Analysis plot (PCA). Moreover, association between geographical area and grouping of genotypes was determined by Canonical Correspondence Analysis (CCA). RESULTS Our meta-analysis showed that rs361525 and rs1800629 were not significantly associated with the risk of HCC. CCA analysis illustrated that there was not any correlation between genotype distribution and geographical distance for rs1800629 but there was significant correlation between genotype distribution and geographical features for rs361525. PCA analysis for both SNPs showed India and Korea were placed near each other and also China and Brazil were in same part of PCA plot. CONCLUSION To sum up, this meta-analysis suggests that the rs361525 and rs1800629 are not associated with HCC development while geographical distance effect on rs361525 genetic inheritance but not effect on rs1800629. However, it is necessary to conduct further studies with larger sample. Moreover, gene-gene and gene-environment interactions should also be considered.

Abstract
Objectives. To investigate the potential association of tumor necrosis factor-α T-857C polymorphism with susceptibility to the five common malignant tumors. Materials and Methods. A comprehensive search of PubMed/Medline, Embase, and Web of Science databases was performed up to November 2015. Pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated to assess the strength of the association. Subgroup analysis, heterogeneity analyses, and publication bias were also texted in the meta-analysis. Results. A total of twenty-two publications involving 5215 cases and 6755 controls were recruited. Overall, the meta-analysis revealed an increased risk between the TNF-α T-857C polymorphism and gastric cancer susceptibility in T versus C model, heterozygote genetic model, and dominant genetic model. An increased risk between the TNF-α T-857C polymorphism and hepatocellular cancer susceptibility in homozygote genetic model and recessive genetic model was also found. No significant association was found between the TNF-α T-857C polymorphism and colorectal cancer, cervical cancer, and prostate cancer. Conclusions. Our meta-analyses suggest that TNF-α T-857C polymorphism may be associated with increased risk of gastric cancer and hepatocellular cancer development. Therefore, the TNF-α T-857C polymorphism could be considered as one possible risk factor of gastric cancer and hepatocellular cancer according to our study.

Abstract
BACKGROUND To assess the association between tumor necrosis factor-alpha (TNF-α) G308A, G238A and C863T polymorphisms and hepatitis B virus related hepatocellular carcinoma (HBV-HCC) susceptibility. METHODS We interrogated the databases of Pubmed, Sciencedirect and Viley online library up to March 8, 2016. Odds ratios (ORs) and corresponding 95% confidence intervals (95%CIs) were calculated in a fixed-effects model or a random-effects model when appropriate. RESULTS In total, 12 case-control studies which containing 1580 HBV-HCC cases, 2033 HBV carrier controls, 395 HBV spontaneously recovered (SR) controls and 1116 healthy controls were included. Compared with GG genotype, the genotypes GA/AA of G308A were associated with a significantly increased HBV-HCC risk when the controls were all healthy individuals (AA vs. GG, OR 2.483, 95%CI 1.243 to 4.959; GA vs. GG, OR 1.383, 95%CI 1.028 to 1.860; GA/AA vs. GG, OR 1.381, 95%CI 1.048 to 1.820). Meanwhile, only the AA vs. GG model of G238A and HBV-HCC showed a statistic significance when the controls were healthy individuals (OR 4.776, 95%CI 1.280 to 17.819). CT genotype of TNF-α C863T could increase HBV-HCC risk whenever the controls were healthy individuals, HBV carriers or HBV recovers. CONCLUSION This meta-analysis shows that AA genotype in TNF-α G308A and TNF-α G238A and CT genotype in TNF-α C863T may increase HBV-HCC risk. Therefore, HBV infection seemed to be a more important factor for tumorigenesis of HCC than genetic predisposition in G308A of TNF-α, and interaction between TNF-α C863T polymorphisms and HBV infection might be associated with increased HCC risk.

Abstract
Hepatocellular carcinoma (HCC) is a primary liver cancer, which is one of the most prevalent cancers among humans. Many factors are involved in the liver carcinogenesis as lifestyle and environmental factors. Hepatitis virus infections are now recognized as the chief etiology of HCC; however, the precise mechanism is still enigmatic till now. The inflammation triggered by the cytokine-mediated immune response, was reported to be the closest factor of HCC development. Cytokines are immunoregulatory proteins produced by immune cells, functioning as orchestrators of the immune response. Genes of cytokines and their receptors are known to be polymorphic, which give rise to variations in their genes. These variations have a great impact on the expression levels of the secreted cytokines. Therefore, cytokine gene polymorphisms are involved in the molecular mechanisms of several diseases. This piece of work aims to shed much light on the role of cytokine gene polymorphisms as genetic host factor in hepatitis related HCC.
