白细胞介素-6及其受体在子宫肌瘤的表达及意义

目的 研究白细胞介素-6(IL-6)与IL-6受体(IL-6R)在子宫肌瘤的表达及意义.方法 选择因子宫肌瘤行子宫全切除的患者20例,对于子宫肌瘤和同源正常子宫平滑肌,分别采用western blot和荧光定量PCR检测IL-6的表达;western blot和RT-PCR检测IL-6R的表达.结果 IL-6蛋白和mRNA在正常子宫平滑肌表达明显高于子宫肌瘤[(0.7996±0.0359)比(0.6904±0.0414)和(0.0470 ±0.0071)比(0.0283±0.0045)],差异均有统计学意义(P均＜0.05);而IL-6R蛋白和mRNA表达在肌瘤与平滑肌间差异无统计学意义[(0.7105±0.0520)比(0.6904±0.0532)和(0.6644±0.0537)比(0.6465±0.0501),P均＞0.05)].结论 子宫肌瘤局部IL-6低表达可能在一定程度上参与肌瘤的发病,而IL-6R未参与子宫肌瘤发病.

Expression and clinical significance of IL-6 and IL-6 receptor in hysteromyoma

Objective To investigate the expression and significance of IL-6 and IL-6 receptor (IL-6R)in hysteromyoma.Methods The expression of IL-6 in hysteromyoma and homologous normal myometrium of 20 cases undergoing total hysterectomy were detected by fluorescent quantitative PCR and western-blot,respectively while IL6R was examined by western-blot and RT-PCR.Results The expression of IL-6 protein and mRNA in homologous normal myometrium were obviously higher than that in hysteromyoma[(0.7996 ±0.0359)vs (0.6904 ±0.0414)and (0.0470±0.0071)vs(0.0283±0.0045 ),P＜0.05] ;No difference was observed in IL-6R protein and mRNA expression between leiomyomas and myometrium[(0.7105 ±0.0520)vs (0.6904 ±0.0532)and (0.6644 ±0.0537 )vs (0.6465±0.0501),P＞0.05 ].Conclusion The lower expression of IL-6 in leiomyomas may contribute to the pathogenesis of hysteromyoma to some extent,and there is no relationship between IL-6R and hysteromyoma.
