چکیده
AIM To assess the role of pro- and anti-inflammatory polymorphisms in gastric cancer susceptibility. PATIENTS AND METHODS We genotyped 12 polymorphisms in eight cytokine genes (Interleukin-1β -IL1B-, IL8, IL17A, IL17F, IL32, tumor necrosis factor-α -TNF-, IL1RN, IL10) in a case-control study of 147 patients with gastric cancer and 172 controls. RESULTS Single polymorphism analysis revealed an association between the IL10 -592C>A single nucleotide polymorphism and cases with moderately- or well-differentiated tumors [AA vs. GG, odds ratio (OR)=3.01; 95% confidence interval (CI)=1.08-8.50]. We further analyzed gene-gene interactions using a combined attribute network implemented in multifactor dimensionality reduction software. The analysis revealed an interaction between IL8 -251A>T and IL32 rs28372698 SNPs among cases with moderately- or well-differentiated tumors. Homozygosity for both IL8 -251T and IL32 T alleles increases the odds for developing gastric cancer up to 2.63-fold (OR=2.63; 95% CI=1.15-6.03). This association was higher compared to the homozygosity for the IL8-251 T allele alone (OR=1.11; 95% CI=0.51-2.43) or the IL32 T allele alone (OR=1.21; 95% CI=0.54-2.72). CONCLUSION These findings suggest that IL10 -592C>A increases the odds for developing gastric cancer. An interaction between IL8 -251A>T and IL32 rs28372698 SNPs is also proposed.

Background: Gastric cancer is one of the most common malignancies in the world. It may result from a defect in the genes involved in DNA repair. One of the essential genes in the repair pathway is the XRCC1 gene that its polymorphisms in the human population play a role in gastric cancer susceptibility. The main purpose of this study was to investigate the association of 194C/T and 399G/A polym...
متن کاملStudy of cyp2E1 gene RsaI/PstI polymorphisms in patients with gastric cancer in north of Iran
Background: North of Iran is amongst high incidence rate areas of gastric carcinoma where environmental carcinogenic compounds especially agricultural pesticides are massively used. Cytochrome P450 2E1 (CYP2E1) enzyme metabolically activates a large number of low molecular mass xenobiotics. The polymorphic nature of cyp2E1 gene control elements is associated with interindividual differences...

Introduction: Single nucleotide polymorphisms result in dysregulation of the proto-oncogene TCF3 gene, which is associated with the development, metastasis, and chemoresistance of different malignancies. Methods: GSE10810 microarray dataset and GEPIA2 online software were used to find differentially expressed genes and the TCF3 status in breast cancer (BC) and gastric cancer (GC), respectively....

Gastric cancer (GC) is the second leading cause of cancer-related deaths worldwide. It has been proposed that the specific genotypes of Helicobacter pylori (H. pylori) are the causative agents in the development of gastroduodenal diseases, such as chronic atrophic gastritis, peptic ulcerations, and GC. However, disease progression to GC occurs in only a small proportion of infected patients. Re...
