Abstract
OBJECTIVE There are inconclusive data connecting single-nucleotide polymorphisms (SNPs) of TNF-α (rs361525) and TNF-β (rs909253) to potential malignant oral disorder (PMOD) such as lichen planus and oral fibrosis. Here, we have investigated the risk of oral squamous cell carcinoma as well as oral pre-cancerous lesions in North Indian population with the polymorphism of the TNFα/ β genes. MATERIAL AND METHODS A total 500 patients with oral pre-cancer and OSCC and 500 healthy volunteers were genotypes for the TNF-α (-238) G/A (rs361525) and TNF-β (252) A/G (rs909253) gene polymorphism. Genotypes were identified by polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP). Genotype frequencies were evaluated by Chi-square test. RESULTS Compared to the GG genotype, the GA genotype of TNF-α (G238A) polymorphism (rs361525) has been found to significantly increase the risk of oral disease (OR = 1.99) and especially the risk of lichen planus and OSCC (OR = 2.805 and 5.790, respectively). Similarly, the risk of oral disease was also more in the heterozygote (AG) than the common allele homozygote (AA) of TNF-β (A252G) polymorphism (rs909253) (OR = 1.483). CONCLUSION We conclude that the SNPs rs361525 and rs909253 were significantly associated with oral pre-cancer and OSCC.

Polymorphisms of TNF- α -308 G/A and IL-8 -251 T/A Genes Associated with Urothelial Carcinoma: A Case-Control Study. BIOMED RESEARCH INTERNATIONAL 2018; 2018:3148137. [PMID: 29951534 PMCID: PMC5987345 DOI: 10.1155/2018/3148137] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 04/01/2018] [Accepted: 04/10/2018] [Indexed: 01/19/2023]
Abstract
Cigarette smoking and exposure to environmental tobacco smoke are well-known risk factors for urothelial carcinoma (UC). We conducted a hospital-based case-control study involving 287 UC cases and 574 cancer-free controls to investigate the joint effects of cigarette smoking and polymorphisms of inflammatory genes on UC risk. Tumor necrosis factor alpha (TNF-α) -308 G/A and interleukin-8 (IL-8) -251 T/A polymorphisms were determined using a polymerase chain reaction-restriction fragment length polymorphism method. People who had ever smoked and those who were exposed to environmental tobacco smoke had significantly increased UC odds ratios (ORs) of 1.65 and 1.68, respectively. Participants who had smoked more than 18 pack-years had a significantly increased UC OR of 2.64. People who had ever smoked and who carried the A/A genotype of the TNF-α -308 G/A polymorphism had a significantly higher UC OR (10.25) compared to people who had never smoked and who carried the G/G or G/A genotype. In addition, people who had ever smoked and who carried the IL-8 -251 T/T genotype had a significantly increased UC OR (3.08) compared to people who had never smoked and who carried the T/A or A/A genotype. In a combined analysis of three major risk factors (cumulative cigarette smoking, the TNF-α -308 A/A genotype, and the IL-8 -251 T/T genotype), subjects with any one, any two, and all three risk factors experienced significantly increased UC ORs of 1.55, 2.89, and 3.77, respectively, compared to individuals with none of the risk factors. Conclusions. Our results indicate that the combined effects of cumulative cigarette exposure and the TNF-α -308 A/A genotype and/or the IL-8 -251 T/T genotype on UC OR showed a significant dose-response relationship.

Abstract
Background Inflammation constitutes one of the important components of colorectal cancer (CRC) pathogenesis. Tumor necrosis factor-α (TNF-α), a cytokine and an important inflammatory mediator plays a pivotal role in the malignant cellular proliferation, angiogenesis, tissue invasion and metastasis in CRC. The studies on association of various polymorphisms in human TNF-α gene including TNF-α-308G/A single nucleotide polymorphism (SNP) are limited, mixed and inconclusive. Materials and methods The aim of this study was to analyze the association of TNF-α-308G/A promoter SNP with colorectal cancer (CRC) susceptibility and development risk and also to evaluate the modifying effects of possible TNF-α-308G/A genotypes on different risk factors of CRC in ethnic population of Kashmir, India through a case–control setup. The genotype frequencies of TNF-α-308G/A promoter SNP were compared between 142 CRC patients and 184 individually matched healthy controls by using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. The associations between the TNF-α-308G/A SNP and CRC risk were examined through conditional logistic regression models adjusted for multiple possible confounding (third) variables. Further, the associations between this SNP and various clinico-pathological parameters, demographic variables and environmental factors within the case group subjects with regard to CRC risk were also evaluated. Results The association between the TNF-α-308G/A SNP and the modulation of risk of CRC was not found to be significant (p value = 0.156). The effect of less common TNF-α-308A allele on the risk of colorectal cancer was also not found to be significant (p value = 0.175). The variant genotype (AA) was nonexistent in the study population. Further, we found no significant effect modulation of CRC risk by wild and heterozygous TNF-α-308G/A SNP genotypes in presence of different possible risk factors (p > 0.05). We also found no significant association of TNF-α-308G/A SNP with the subsets of various characteristics of the case group subjects under study (p > 0.05). Conclusions This study indicates that there is no significant association between the TNF-α-308G/A promoter SNP and the risk of developing CRC in ethnic Kashmiri population. However, in order to substantiate our findings, this study needs to be replicated with bigger sample size and should involve other ethnically defined populations with high CRC risk.

Abstract
Brain abscess develops in response to a parenchymal infection. Intercellular adhesion molecule-1 (ICAM-1) and monocyte chemoattractant protein-1 (MCP-1) play vital role in central nervous system (CNS) diseases. We studied ICAM-1 (K469E) and MCP-1 (-2518 A>G) polymorphisms among brain abscess patients. The genotypic distributions of ICAM-1 (K469E) and MCP-1 (-2518 A>G) were significantly different between patients and controls. Further, patient with predisposing factors, and also with culture result, we found significant association. The study revealed that the polymorphisms of these molecules lead to increased production, which appears to be a risk for the development of brain abscess.

Abstract
Nasopharyngeal carcinoma (NPC) is an epithelial tumour with a distinctive racial and geographical distribution. High incidence of NPC has been reported from China, Southeast Asia, and northeast (NE) region of India. The immune mechanism plays incredibly role in pathogenesis of NPC. Tumour necrosis factors (TNFs) and heat shock protein 70 (HSP 70) constitute significant components of innate as well as adaptive host immunity. Multi-analytical approaches including logistic regression (LR), classification and regression tree (CART) and multifactor dimensionality reduction (MDR) were applied in 120 NPC cases and 100 controls to explore high order interactions among TNF-α (-308 G>A), TNF β (+252 A>G), HSP 70-1 (+190 G>C), HSP 70-hom (+2437 T>C) genes and environmental risk factors. TNF β was identified as the primary etiological factor by all three analytical approaches. Individual analysis of results showed protective effect of TNF β GG genotype (adjusted odds ratio (OR2) = 0.27, 95 % CI = 0.125-0.611, P = 0.001), HSP 70 (+2437) CC genotype (OR2 = 0.17, 95 % CI = 0.0430.69, P = 0.013), while AG genotype of TNF β was found significantly associated with risk of NPC (OR2 = 1.97, 95 % CI = 1.019-3.83, P = 0.04). Analysis of environmental factors demonstrated association of alcohol consumption, living in mud houses and use of firewood for cooking as major risk factors for NPC. Individual haplotype association analysis showed significant risk associated with GTGA haplotype (OR = 68.61, 95 % CI = 2.47-190.37, P = 0.013) while a protective effect with CCAA and GCGA haplotypes (OR = 0.19, 95 % CI = 0.05-0.75, P = 0.019; OR = 0.01 95 % CI = 0.05-0.30, P = 0.007). The multi-analytical approaches applied in this study helped in identification of distinct gene-gene and gene-environment interactions significant in risk assessment of NPC.

The IL-1RN and IL-4 gene polymorphisms are potential genetic markers of susceptibility to bladder cancer: a case-control study. World J Urol 2014; 33:389-95.

Abstract
PURPOSE We investigated the relationship between the distribution of the IL-1RN, TNF-β and IL-4 polymorphism and the clinical features of bladder cancer. MATERIALS AND METHODS A total of 100 patients with bladder carcinoma and 102 healthy control subjects were enrolled in the study. The IL-1RN, IL-4 and TNF-β gene polymorphisms were identified by PCR restriction fragment length polymorphism-based analysis. Allelic frequencies were compared between patient and the controls. Tumor stage, histopathological grade, tumor size/number and smoking condition were evaluated with IL-1RN, IL-4 and TNF-β gene polymorphisms. RESULTS Allele distribution frequencies of IL-1RN and IL-4 gene polymorphisms were significantly different between patients and control groups. However, allele distribution of TNF-β gene was not statistically significant. There was no difference in allele distribution of the three genes in both groups regarding stage, tumor size, number of tumors and smoking condition. Although allele distribution of IL-4 gene showed significant difference considering histopathological grades in both smoking and total patients group, allele distribution of IL-1RN and TNF-β was not different. CONCLUSION The present research suggests that the IL-1RN and IL-4 gene polymorphisms are potential genetic markers of susceptibility to bladder cancer. In the future, clinical improvements on diagnosis, treatment and prognosis of bladder carcinoma are expected owing to development of more sensitive and specific tests for genetic polymorphisms of cytokines that are effective on inflammation.

Abstract
Chronic exposure to arsenic can generate reactive oxidative species, which can induce certain proinflammatory cytokines such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and interleukin-8 (IL-8). TNF-α, IL-6 and IL-8 have been shown to be involved in the development and progression of various cancers, including bladder cancer. This study aimed to investigate the joint effect of the polymorphism of TNF-α -308 G/A, IL-6 -174 G/C, IL-8 -251 T/A and urinary arsenic profiles on urothelial carcinoma (UC) risk. This study evaluated 300 pathologically-confirmed cases of UC and 594 cancer-free controls. Urinary arsenic species were detected using high-performance liquid chromatography-linked hydride generator and atomic absorption spectrometry. The polymorphism of TNF-α -308 G/A, IL-6 -174 G/C and IL-8 -251 T/A was determined using polymerase chain reaction-restriction fragment length polymorphism. The joint effects on UC risk were estimated by odds ratios and 95% confidence intervals using unconditional logistic regression. We found that the TNF-α -308 A/A and IL-8 -251 T/T polymorphisms were significantly associated with UC. Moreover, significant dose-response joint effect of TNF-α -308 A/A or IL-8 -251 T/T genotypes and arsenic methylation indices were seen to affect UC risk. The present results also showed a significant increase in UC risk in subjects with the IL-8 -251 T/T genotype for each SD increase in urinary total arsenic and MMA%. In contrast, a significant decrease in UC risk was found in subjects who carried the IL-8 -251 T/T genotype for each SD increase in DMA%.

Abstract
BACKGROUND The genetic basis of susceptibility to hepatocellular carcinoma (HCC) is poorly understood. Tumor necrosis factor alpha (TNF-α) is a cytokine that may act as an endogenous tumor promoter. The association between TNF-α 308 G/A polymorphism and HCC risk remains unclear. AIM The aim of this study was to investigate the association between TNF-α 308 G/A polymorphism and HCC risk in a Chinese population. METHODS The study population consisted of 88 patients with documented HCC and 88 healthy controls. The gene polymorphism of TNF-α was analyzed by polymerase chain reaction-restriction fragment length polymorphism assay. RESULTS HCC patients had a significantly lower frequency GG (odds ratio=0.36; 95% confidence interval=0.13, 0.94; p=0.04) and G allele (odds ratio=0.58; 95% confidence interval=0.37, 0.90; p=0.01) than healthy controls. When stratifying for tumor size and cirrhosis, no statistically significant results were found. CONCLUSION This study suggested that TNF-α -308GG and G allele were associated with a modest decrease in the risk of HCC in Chinese population.

Abstract
Tumor necrosis factor-alpha (TNF-alpha) polymorphisms with increased expression is associated with many autoimmune and inflammatory diseases. Possible role of TNF-alpha polymorphism in the pathogenesis of Guillain-Barré syndrome (GBS) largely remains unknown. We investigated polymorphisms in the promoter region of TNF-alpha gene and its expression in GBS patients and healthy controls. TNF-alpha (-308 G>A, -857 C>T, and -863 C>A) polymorphisms in 140 GBS patients and 206 healthy controls were studied using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele specific-PCR. TNF-alpha level in serum by ELISA was determined in 60 patients and an equal number of controls. Prevalence of TNF-alpha -308 G > A polymorphic A allele was associated with increased risk of GBS (p < 0.001; OR = 2.58, 95% CI = 1.61-4.14). Heterozygous genotype (G/A) had an association with acute motor axonal neuropathy (p < 0.001; OR = 4.23, 95% CI = 2.00-8.95) and variant genotype A/A with both axonal subtypes, acute motor axonal neuropathy (p = 0.015, OR = 7.00, 95% CI = 1.46-33.57) and acute motor sensory axonal neuropathy (p = 0.017; OR = 7.73, 95% CI = 1.44-41.37). Variant genotype T/T of TNF-alpha -857 C>T polymorphism was also significantly associated with acute motor axonal neuropathy (p = 0.034; OR = 3.93, 95% CI = 1.11-13.91). Patients with A and T alleles had higher TNF-alpha level in serum. TNF-alpha -308 G > A and -857 C>T (only T/T) polymorphisms with increased TNF-alpha level may predict susceptibility to axonal subtypes of GBS.

Abstract
Many markers for the detection of bladder cancers have been tested and almost all urinary markers reported are better than cytology with regard to sensitivity, but they score lower in specificity. Currently molecular and genetic changes play an important role in the discovery of new molecular markers for detection, prognostication and surveillance. The purpose of this review is to highlight the most important urinary molecular biomarker developments that have been studied and reported recently. In the current review we have summarized the most recent and relevant published reports on molecular urinary markers. The results of this review show that the first generation of urinary markers did not add much to urinary cytology. The current generation of markers is better, but additional clinical trials are needed. Our knowledge of molecular pathways in bladder cancer is growing and new methods of marker development emerge, but the perfect marker is still to be found. Currently, there are not clinically usable molecular markers that can guide us in diagnosis or surveillance, nor guide us in lowering the frequency of urethrocystoscopy in bladder cancer.

Abstract
OBJECTIVE To investigate the association of tumour necrosis factor-alpha gene (TNF-alpha) polymorphisms T-1031C, C-863A, and C-857T with bladder cancer risk and recurrence after bacille Calmette-Guérin (BCG) immunotherapy, as TNF-alpha regulates inflammatory process influencing bladder cancer susceptibility and outcome of BCG immunotherapy. PATIENTS AND METHODS In all, 220 patients with bladder cancer and 206 controls were recruited. Genotyping was done using allele specific-polymerase chain reaction. RESULTS A T-1031C, CC genotype and haplotype -1031C/-863C/-857T showed enhanced susceptibility to bladder cancer, with an odds ratio (OR) of 2.23 and 95% confidence interval (CI) of 1.17-4.26; and an OR of 6.05 and 95%CI of 2.46-14.90, respectively. A T-1031C, CC genotype had a reduced risk of recurrence after BCG treatment (hazard ratio 0.38, 95%CI 0.14-0.98). CONCLUSION The present data suggests that T-1031C (CC) genotype and C/C/T haplotype may confer risk for bladder cancer, moreover T-1031C (CC) decreased the risk of recurrence after BCG immunotherapy.

Abstract
BACKGROUND Lymphotoxin-alpha (LTA) is a pro-inflammatory cytokine with anti-tumor activity. The objective of this study was to determine whether LTA polymorphisms influence the presence of cancer. METHODS LTA polymorphisms C804A (rs1041981, T60N) and T495C (rs2229094, C13R) were determined in 1,536 consecutive autopsy cases and were registered in the Japanese single-nucleotide polymorphisms (SNPs) for geriatric research (JG-SNP) Internet database. Tumors were systematically reviewed, pathologically confirmed, and assessed in relation to LTA genotype. RESULTS The study population consisted of 827 males and 709 females, with a mean age of 80 years. Altogether, we studied 606 subjects without cancer and 930 subjects with cancer of the stomach (n = 183), lung (n = 164), colon or rectum (n = 143), or other sites. The presence of cancer was higher in males than in females. The C804A and T495C polymorphisms were associated with cancer in males (CA + AA: CC, adjusted OR = 0.72, 95% CI = 0.53 - 0.99; TC + CC: TT, adjusted OR = 1.45, 95% CI = 1.04 - 2.02; respectively) but not in females. In males, the C804A polymorphism was associated with lung cancer (CA + AA: CC, adjusted OR = 0.60, 95% CI = 0.37 - 0.97), whereas the T495C polymorphism was associated with gastric cancer (TC + CC: TT, adjusted OR = 1.68, 95% CI = 1.06 - 2.65). CONCLUSION We found some evidence of an association between LTA polymorphisms and cancer risk in elderly Japanese men. Further studies in larger populations should examine this hypothesis.

Gupta R, Sharma SC, Das SN. Association of TNF-alpha and TNFR1 promoters and 3' UTR region of TNFR2 gene polymorphisms with genetic susceptibility to tobacco-related oral carcinoma in Asian Indians. Oral Oncol 2008; 44:455-63. [PMID: 18206417 DOI: 10.1016/j.oraloncology.2007.06.003] [Citation(s) in RCA: 39] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2007] [Revised: 06/05/2007] [Accepted: 06/06/2007] [Indexed: 01/20/2023]
Abstract
Tobacco-related oral squamous cell carcinoma is a common malignancy in Asian people. It accounts for almost 40% of cancers among Indian men and 3% in the Western world. Smokeless tobacco has been shown to induce tumor necrosis factor-alpha (TNF-alpha), which, along with its receptors, is over-expressed in people with oral carcinoma. Single nucleotide polymorphisms (SNPs) in TNF-alpha and TNF receptor genes may affect their expression and may be a potential determinant of susceptibility to tobacco-related oral carcinomas. We assessed SNPs in TNF-alpha(-308, -238) and TNF receptor 1 (TNFR1; -609) promoters by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and at four sites of TNF receptor 2 gene (TNFR2; exon 9 site 1176; exon 10 sites 1663, 1668 and 1690) by PCR-sequence-specific primers (PCR-SSP) techniques, respectively, in 94 patients and 130 healthy controls. TNF-alpha-308 G allele was significantly lower (Pc=0.004; OR=3.85), whereas A allele was significantly higher (Pc=0.004; OR=0.25) in patients compared with controls. No significant change was observed at -238 promoter site between the two groups. In the case of TNF receptors, both TNFR1 -609 TT (Pc=0.006; OR=15.3) and TNFR2 1690 CT (Pc=0.018; OR=5.6) genotypes were significantly lower in patients compared with controls. It seems that TNF-alpha-308 G/A may be related to susceptibility, whereas -609 TT TNFR1 and 1690 C/T TNFR2 SNPs may be protective to tobacco-related oral squamous cell carcinoma. These SNPs may be useful as a marker for high-risk groups among Asian Indians.
