Abstract:
Objective To detect the distribution of site-174G/C,site-572C/G and site-597G/A of interleukin-6 gene promoter regions in patients with endometriosis,and to analyze polymorphism of the promoter.Methods Interleukin-6 gene promoter region polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism in patients with endometriosis(n=98)and normal controls(n=99).Among the 98 patients with endometriosis,22 were defined as stageⅡ,35 as stage Ⅲ and 41 as stage Ⅳ.Comparisons between the two groups on the genotype of IL-6 gene promoter and the distributed allele frequency were done,and also among the patients of stage Ⅱ,Ⅲ and Ⅳ once significant differences were detected in genotype frequency or allele frequency in disease group and control group.Results At the site-174,the frequencies of GG,GC and CC genotypes were 100%,0% and 0%,respectively,in patients with endometriosis,while 98.99%,1.01% and 0%,respectively,in normal controls.No significant difference was found in the distribution frequency of IL-6 genotype between patients with endometriosis and normal controls.At the site-572,the frequencies of CC,CG and GG genotypes were 55.10%,42.86% and 2.04%,respectively,in patients with endometriosis,while they were 70.71 %,28.28% and 1.01%,respectively,in normal controls.A significant difference existed between the two groups.At the site-597 of IL-6 gene,no GA and AA genotypes were found in the two groups.At the site-572,the frequencies of CC,CG and GG genotypes were 59.09%,40.90% and 0%,respectively,in patients with endometriosis of stage Ⅱ,54.29%,42.86% and 2.85% in patients of stage Ⅲ,and 53.66%,43.90% and 2.44% in patients of stage Ⅳ.No significant difference was found among the three groups.Conclusion Mutations at the sites-174 and-597 of IL-6 gene promoter region were rare.Their distribution frequencies have nothing to do with morbidity of endometriosis.While at the site-572,its distribution frequency of genotype shows correlation with morbidity of endometriosis but does not show correlation with the extent of endometriosis.
