To characterize the in vivo expression of immunosuppressive cytokines in gastric cancer, we analyzed the messenger RNA (mRNA) expression of transforming growth factor-beta (TGF-beta) and interleukin-10 (IL-10) in human gastric carcinoma tissues.
These findings suggest that genetic polymorphisms in IL-8, IL-10 and TNFalpha may play important roles in developing gastric cancer in the Chinese population.
We aimed to test for associations between polymorphisms in IL1B (-31 and +3954), IL10-592 and IL1RN variable number of tandem repeats (VNTR) and risk of gastric cancer in a Mexican population.
The IL-10-1082/-819/-592 genotype status and haplotype were associated with an increased risk for gastric cancer development, not peptic ulcer, in Japan.
We thus concluded that IL-10 gene transfer in PMCs could be a new strategy for the prevention of peritoneal dissemination of gastric cancer due to the resulting persistently high IL-10 concentration in the peritoneal cavity.
This meta-analysis suggests that the IL-10 -1082 promoter polymorphism may be associated with gastric cancer among Asians, and that differences in genotype distribution may be associated with the location of gastric cancer.
IL-1beta+3954_T/C (OR 2.1, 1.0-4.3), IL-1RN*2/L (OR 3.5, 1.7-7.3) and IL-10-592_C/A (OR 3.2, 1.5-6.8) were individually associated with GC, and a combination of these cytokine polymorphisms with H pylori vacA s1b and m1 further increased the risk (OR 7.2, 1.4-36.4).
Our results suggest that the HLA class II and IL-10-592A/C polymorphisms synergistically affect the susceptibility to GC development of H. pylori-infected individuals in the Japanese population.
This meta-analysis suggests that the IL10 -592 promoter polymorphism may be associated with gastric cancer among Asians, and that differences in genotype distribution may be associated with the location and Lauren's classification of gastric cancer.
Therefore, we designed this study to investigate whether polymorphisms of the IL10 gene were associated with cachexia in patients with low-third gastric cancer in a Chinese population.
This finding, taken together with previous evidence, provides a possible explanation for previous discrepant association results and supports the idea that IL10 gene polymorphisms can differentially affect GC development among populations.
The objective of this study was to investigate the association between IL-10 -1082 promoter polymorphism and gastric cancer risk in Chinese Han patients.
This study indicates that the LTA +252G allele is associated with increased risk for the presence of GC in a Helicobacter pylori infection positive subgroup and potential interaction between IL-10 and LTA may contribute to the risk of GC.
In this article, the present author explored the roles of H. pylori infection and IL-10 promoter polymorphisms in development of gastric cancer in this area.
In addition, H. pylori-positive smokers who were carriers of either the IL10-1082G (OR [95% CI] = 17.76 [6.17-51.06]) or the -592C (OR [95% CI] = 8.37 [2.79-25.16]) allele had an increased risk of intestinal-type gastric cancer compared to H. pylori-negative nonsmokers homozygous for IL10-1082A and -592A, respectively.
IL-10-819 TT genotype is not statistically associated with the overall reduced gastric cancer susceptibility in persons with H. pylori infection compared with controls without H. pylori infection.
The other three SNPs, the allele "C" of rs1800871 in IL10 (OR = 1.33, 95% CI = 1.04-1.90; P = 0.026 in the additive model; OR = 1.46, 95% CI = 1.04-2.06; P = 0.030 in the recessive model), the allele "A" of rs2976391 in PSCA (OR = 1.30, 95% CI = 1.01-1.66; P = 0.041 in the additive model and OR = 1.48, 95% CI = 1.04-2.11, P = 0.028 in the recessive model), and the allele "G" of rs17109928 in NOC3L gene (OR = 1.34, 95% CI = 1.01-1.78; P = 0.042 by additive model analysis; OR = 1.47, 95% CI = 1.04-2.07, P = 0.028 by dominant model analysis), showed an association with an increased risk of gastric cancer.
IL-10-592 AA genotype is also associated with the overall reduced gastric cancer susceptibility in persons with H. pylori infection compared with controls without H. pylori infection, suggesting IL-10-592 AA genotype may seem to be more protective from overall gastric cancer susceptibility in persons infected with H. pylori.
