CXCL12 rs266085 and TNF-? rs1799724 polymorphisms and susceptibility to cervical cancer in a Chinese population.

ABSTRACT: Further research is required to identify single nucleotide polymorphisms (SNPs) associated with cervical cancer. The aim of this study was to assess the association of TNF-?/rs1799724 and CXCL12/rs266085 polymorphisms with susceptibility to cervical cancer in Han Chinese population in Shandong Province. 348 patients with cervical squamous cell carcinoma, including CIS (121) and invasive carcinoma (227), and 351 healthy controls. Genomic DNA was isolated from peripheral blood and genotyping for TNF-?/rs1799724 and CXCL12/rs266085 was carried out using TaqMan SNP Genotyping Assays. TNF-?/rs1799724 polymorphism showed the C-allele was less prevalent among cases as compared to controls (74.3% vs. 92.0%), while the T-allele was more prevalent among cases (P=0.000, OR=3.99, 95% C.I.: 2.90-5.51). CXCL12/rs266085 polymorphism showed the C-allele was less prevalent among cases as compared to controls (41.2% vs. 49.7%), while the T-allele was more prevalent among cases (P=0.001, OR=1.41, 95% C.I.: 1.14-1.74). The genotype and allele frequencies of these two SNPs did not differ between CIS and invasive squamous cell carcinoma (P>0.05). Moreover, the allele frequencies of rs1799724 were significantly different between controls without or with HPV infection (P<0.05). Neither the genotype nor allele frequencies of rs266085 were statistically different between HPV-negative and positive controls. TNF-?/rs1799724 and CXCL12/rs266085 polymorphisms are associated with cervical cancer. C->T polymorphism of these two SNPs and HPV infection are linked to high risk for cervical cancer.

Project description:BackgroundThe tumour necrosis factor-α (TNF-α) gene plays an important role in the host immune response, which will influence the development and clearance of cancer. Polymorphism of the TNF-α promoter region is considered to influence its transcription and be a risk factor for tumorigenesis. In the current study, we evaluated the role of TNF-α promoter region polymorphisms in susceptibility to cervical intraepithelial neoplasia (CIN) and cervical cancer (CC).MethodsA total of 2732 subjects, including 1173 healthy controls, 579 patients with CIN and 980 patients with CC in a Chinese Han population, were selected for the current study. Five SNPs in the TNF-α promoter, rs1799964 (-1031 C>T), rs1800630 (-863 A>C), rs1799724 (-857 C>T), rs1800629 (-308 A>G) and rs361525 (-238 A>G), were selected and genotyped using TaqMan Assays. The association of these SNPs with CIN and cervical cancer was evaluated among healthy controls, CIN and CC patients.ResultsThe frequency distribution of rs1800629 and rs361525 alleles was significantly different between the CC group and the control group (P=0.009 and P=0.002). The rs1800629 A allele was found to be a protective factor for CC (OR=0.72; 95% CI=0.56-0.92). The rs361525 A allele was found to be a risk factor for CC (OR=1.69; 95% CI=1.21-2.38). After pathological subtyping of CC, the allele distribution of rs1800629 and rs361525 were both significantly different between the cervical squamous cell carcinoma and control groups (P=0.002 and P<0.001). The rs1800629 A allele was protective factor for cervical squamous cell carcinoma (OR=0.66; 95% CI=0.50-0.86). The rs361525 A allele was a risk factor for cervical squamous cell carcinoma (OR=1.87; 95% CI=1.32-2.65). Moreover, the genotypic frequency of rs361525 was significantly different between cervical cancer stage I and stage II (P=0.003).ConclusionThe rs1800629 and rs361525 in the TNF-α promoter are associated with susceptibility to CC in the Chinese Han population.

Project description:Many epidemiological studies have confirmed that ICAM-1 gene single-nucleotide polymorphisms (SNPs) are associated with susceptibility of various cancers, but there are relatively few studies on the relationship between ICAM-1 gene polymorphisms and the risk of cervical cancer. Therefore, we aimed to explore the potential role of ICAM-1 gene polymorphisms and the combined effect of SNPs in the pathogenesis of cervical cancer in Han women in northern China. This case-control group includes 488 cases of cervical cancer, 684 cases of cervical precancerous lesions, and 510 healthy females. Multiplex polymerase chain reaction (PCR) combined with the next-generation sequencing method was used for the determination of gene polymorphisms (rs5498, rs3093030, and rs281432). In our study, we divide cervical cancer into two subgroups: cervical squamous cell carcinoma (CSCC) group and cervical adenocarcinoma (CAC) group. We analyzed the alleles and genotypes of all research subjects using multivariate logistic regression analysis combined with 10,000 permutation tests. In addition, we also analyzed the distribution of haplotypes of the three SNPs in cervical cancer and cervical precancerous lesions. We found that the T allele and the dominant model of rs3093030 were associated with the susceptibility of cervical cancer (p = 0.042, p = 0.040, respectively). However, the significance disappeared after the Bonferroni correction for multiple testing (p > 0.05). For rs5498, its mutant gene G, the codominant model, and the dominant model could reduce the risk of CAC (p = 0.009, p = 0.028, p = 0.011, respectively). Significant differences remained after Bonferroni correction (p < 0.05, all). In addition, the frequency of haplotype "CTG" was significantly lower in the CAC group than in the controls. In conclusion, the study suggested that ICAM-1 gene polymorphisms may have a potential role in the pathogenesis of cervical cancer in the northern Chinese Han population.
