Relationship between Atrial Fibrillation and the IL-6-174G/C,-572C/G and -597G/A Polymorphism
【摘要】 目的:探讨江苏南通地区汉族人群中白细胞介素(IL)-6-174G/C(rs1800795)、-572C/G(rs1800796)、-597G/A(rs1800797)单核苷酸多态性(SNP)与血清IL-6水平以及房颤发病之间的关系。方法:分别测定房颤组和对照组血清IL-6及其他临床指标,测量左心房长径(LAD);提取基因组DNA,聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术扩增目的基因片段并酶切。结果:房颤组IL-6和LAD与对照组比较差异有统计学意义(P﹤0.01);房颤组IL-6-572C/G基因型分布G/C+G/G明显高于对照组(P﹤0.05),且房颤组G等位基因频率明显大于对照组(P﹤0.01),IL-6-174G/C位点C等位基因突变率极低,IL-6-597G/A未见A等位基因突变。结论:IL-6-572C/G位点G等位基因突变导致了机体血清IL-6水平升高,可能与房颤的发病有关。
【Abstract】 Objective: To explore the relationships among atrial fibrillation (AF), interleukin-6 (IL-6) and single nucleotide polymorphisms (SNP) of the IL-6-174G/C, -572C/G and -597G/A. Methods: The serum levels of IL-6, lipid and other clinical indicators were measured. The left atrial diameter (LAD) was measured by echocardiography (UCG). The frequency distributions of genotypes and alleles of the IL-6-174G/C, -572G/C and -597G/A were amplified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in samples of 127 AF patients. Results: The values of IL-6 and LAD were significantly higher in AF group than those of control group (P < 0.01). The G/C+G/G genotype distribution and G allele frequencies of IL-6-572C/G were significantly higher in AF group than those of control group (P < 0.01). The C allele mutation rate of IL-6-174G/C was minimal in Han population in Jiangsu Nantong, and no A allele mutation in IL-6-597G/A. Conclusion: The results showed that among Han population in Nantong IL-6-572 C/G polymorphic allele G mutation may lead to the increase of serum level of IL-6 in AF group,which may be related to the pathogenesis of AF.
