Abstract:
Objective To analyze the associations of the interleukin-10 (IL-10) promoter-1082G/A and-819C/T single nucleotide polymorphism (SNP) and serum level of IL-10 with intracranial aneurysm (IAs). Methods The polymerase chain reaction (PCR) and DNA direct sequencing methods were used to detect IL-10 gene promoter district two SNP site,-1082G/A and-819C/T genotype frequency and allele frequency in 206 patients with IAs and 187 controls. Chi-square test was used to analyze differences between two groups. The serum level of IL-10 was analyzed by ELISA, and t-test was used to analyze significant differences between two groups. Results There were significant differences in genotypes of GG and GA+AA, as well as the alleles G and A, in-1082G/A locus between IAs group and control group (P<0.01). There were higher frequencies of genotype GA+AA and the allele A in IAs group than those in control group (P<0.01). There was higher risk of suffering IAs in patients with genotype GA+AA (OR=4.137, 95%CI:2.476-6.914) and the allele A (OR=3.368, 95%CI:2.476-4.583). There were higher frequencies of the genotype CT+TT and the allele T in-819C/T locus in IAs group than those of control group (P<0.01). There was higher risk of suffering IAs in patients with genotype CT+TT (OR=3.393, 95%CI:1.952-5.900) and the allele T (OR=3.764, 95%CI:2.730-5.192). The serum level of IL-10 was significantly lower in IAs group than that of control group (P<0.01). Conclusion The IL-10 promoter SNP influences the expression of IL-10. IL-10 promoter-1082G/A and-819C/T polymorphisms are correlated with the formation of IAs.
