Association between IL1B gene and cervical cancer susceptibility in Chinese Uygur Population: A Case-Control study.

ABSTRACT: BACKGROUND:Interleukin-1? (IL-1B) has been recognized as a pro-inflammatory cytokine and associated with tumorigenesis. We aimed to evaluate the contribution of IL-1B polymorphisms to the susceptibility of cervical cancer in Chinese Uygur population. METHODS:Seven variants were genotyped by Agena MassARRAY platform in 267 cervical cancer patients and 302 healthy controls. Allelic, genotypic, and haplotypic association analyses adjusted for age were investigated using odds ratios (OR) and 95% confidence intervals (CI). GEPIA and UALCAN databases were used to evaluate expression and prognostic of IL-1B gene in cervical cancer. RESULTS:Our result revealed IL-1B rs1143627-AA (OR = 1.98, p = 0.029) and rs16944-GG (OR = 2.01, p = 0.025) was associated with an increased risk of cervical cancer. Besides, we also found two protective single nucleotide polymorphisms (SNPs) rs3136558 (OR = 0.63, p = 0.011) and rs1143630 (OR = 0.63, p = 0.019). Haplotype ?TGA? in the block (rs1143630, rs1143627, and rs16944) significantly decreased the susceptibility of cervical cancer (OR = 0.53, p = 0.0007). IL-1B mRNA level was up-regulated in the cervical cancer patients, which was related with poor prognosis in silico. CONCLUSIONS:For the first time, our results provide evidence on polymorphism of IL-1B gene associated with cervical cancer risk in Chinese Uygur population.

Project description:BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common types of liver cancer. It is hypothesized that P2RX7 genetic polymorphisms have strong association with HCC susceptibility. Therefore, a case-control study was designed and performed to verify the association between P2RX7 gene polymorphisms and HCC susceptibility. MATERIAL AND METHODS A total of 646 subjects were recruited in our study, including 323 HCC patients and 323 healthy controls. Five gene polymorphisms, -762C>T (rs2393799), 946G>A (rs28360457), 1513A>C (rs3751143), 1068G>A (rs1718119), and 1096C>G (rs2230911), were selected. Odds ratio (ORs) and 95% confidence interval (CI) were used to quantify the association between P2RX7 gene polymorphisms and the susceptibility to HCC. All tests were performed using SPSS 20 and a 2-sided P value of less than 0.05 was considered to be statistically significant. RESULTS Our results suggest that allelic frequencies of these 5 SNPs all conformed to Hardy-Weinberg equilibrium (HWE). There was no significant difference in genotype and allele distributions of -762C>T and 1096C>G between the case group and the control group. However, an increased risk of HCC was associated with 946G>A (A vs. G: OR=1.48, 95%CI=1.09-2.01, P=0.013; GA+AA vs. GG: OR=1.46, 95%CI=1.03-2.07, P=0.033). A similar increased risk was associated with 1513A>C polymorphism (C vs. A: OR=1.37, 95%CI=1.05-1.79, P=0.021; AC+CC vs. AA: OR=1.40, 95%CI=1.01-1.93, P=0.041). On the other hand, a decreased risk of HCC was associated with gene polymorphism of 1068G>A (A vs. G: OR=0.68, 95%CI=0.51-0.91, P=0.010; GA+AA vs. GG: OR=0.68, 95%CI=0.49-0.96, P=0.027; AA vs. GG: OR=0.42, 95%CI=0.18-0.99, P=0.048). CONCLUSIONS Our results suggest that 3 of the 5 polymorphisms of P2RX7 described above (1513A>C, 946G>A, and 1068G>A) are significantly associated with HCC susceptibility in a Chinese Han population. Studies with larger sample sizes are recommended to confirm whether our results will be applicable to different ethnic populations in China.

Project description:Tuberculosis (TB) is an infectious disease caused by a mycobacterial infection, with high morbidity and mortality worldwide. The pathogenesis of TB is still unclear; however, a growing body of evidence suggests that host genetic factors may play important roles in susceptibility to TB, and different gene polymorphisms in different ethnic and genetic backgrounds may lead to different effects. In view of the above theories, our research group used bioinformatics to screen for 12 single nucleotide polymorphisms (SNPs), including rs1045481, rs1045491, rs2740349, rs10719, rs642321, rs3744741, rs7813, rs3742330, rs3757, rs14035, rs720012, and rs4961280, which are derived from 6 main genes (i.e., GEMIN4, DICER1, DROSHA, DGCR8, AGO2, and RAN) acting in the microRNA-machinery pathway. We then analyzed the correlations between TB patients of Uygur in Xinjiang China and the above SNPs using a case-control study. The results showed that the genotypic distributions of rs720012 (from gene DGCR8) and rs4961280 (from gene AGO2) were not in accordance with the Hardy-Weinberg equilibrium (P?<?.05), so they were deleted. Subjects carrying the rs3742330 AG/GG genotype, rs1045481 GA genotype, rs1045491 CT genotype, and rs7813 AG genotype, respectively, had an increased risk of TB than individuals carrying rs3742330 AA genotype, rs1045481 GG/AA genotype, rs1045491 CC/TT genotype, and rs7813 AA/GG genotype between different groups. Expression quantitative trait loci analysis found that rs3744741 and rs2740349 from gene GEMIN4 had a regulatory effect, while rs3742330 from gene DICER1 had a reverse regulatory effect. Finally, according to the results of Linkage Disequilibrium between SNPs, the haplotype analysis showed that the haplotype of GCTAC from gene GEMIN4 had statistical differences when compared with active and inactive TB. The current experimental results provide a direction for our future research, and the research team will conduct more in-depth studies on the correlation between miRNA and TB.

Project description:Wilms' tumor gene 1 (WT1) single nucleotide polymorphism (SNP), rs16754, has been considered as an independent prognostic factor in patients with acute myeloid leukemia and renal cell carcinoma. However, its biological role in breast cancer has not been reported. To test whether WT1 SNPs can be used as a molecular marker in order to improve the risk stratification of breast cancer, we performed a case-control study including 709 female sporadic breast cancer patients and 749 female healthy control subjects in the Southeast China. Five WT1 SNPs (rs16754, rs3930513, rs5030141, rs5030317, rs5030320) were selected and determined by polymerase chain reaction-ligase detection reaction to assess their associations with breast cancer risk. Results showed the distributions of the alleles of these WT1 SNPs were consistent with data from Chinese population as suggested by the International HapMap Project. Individuals with the minor alleles of rs16754, rs5030317 and rs5030320 showed a significant decrease of breast cancer risk in codominant model (OR = 0.6370, 95% CI: 0.4260-0.9520 for rs16754; OR = 0.5940, 95% CI: 0.3890-0.9070 for rs5030317; OR = 0.5870, 95% CI: 0.3850-0.8960 for 5030320, respectively) and recessive model. Stratified analyses showed the protective effects were more evident in the subjects with age ≤ 50 years or in pre-menopausal status. To explore the potential mechanism, we conducted bioinformatics genotype-phenotype correlation analysis, and found that the mRNA expression level for homozygous rare allele of WT1 gene was lower than that in wild-type and heterozygous group (P = 0.0021) in Chinese population. In summary, our findings indicated that minor alleles of rs16754, rs5030317 and rs5030320 are associated with reduced risk of breast cancer, suggesting that WT1 SNPs may be a potential biomarker of individualized prediction of susceptibility to breast cancer. However, large prospective and molecular epidemiology studies are needed to verify this correlation and clarify its underlying mechanisms.
