摘要: 目的 检测子宫肌瘤组织雌激素受体(ER)亚型α、β及胰岛素样生长因子-1(IGF-Ⅰ)的表达,探讨其与子宫肌瘤发生发展的关系.方法 采用荧光定量PCR方法,检测21例患者的增生期子宫肌瘤组织及6例配对增生期肌层组织中ERαmRNA,ERβmRNA和IGF-ⅠmRNA的表达水平.结果 所有标本均以ERαmRNA表达为主,ERβmRNA表达微弱.ERαmRNA在肌瘤中表达高于肌层,ERβmRNA在肌瘤中表达低于肌层,但差异无统计学意义.IGF-ImRNA的表达在肌瘤中高于肌层(P<0.05).ERαmRNA与IGF-ⅠmRNA表达水平呈正相关(r=0.572,P=0.014);ERβmRNA与IGF-ⅠImRNA表达水平亦呈正相关,但无统计学意义.结论 子宫肌瘤中IGF-ImRNA表达增高,ERαmRNA与IGF-ⅠmRNA表达呈正相关,提示雌激素可能通过ERα上调IGF-ⅠmRNA的表达促进肌瘤生长.

Abstract: Objective Expressions of estrogen receptor α(ERα),β(ERβ)and insulin-like growth factor-Ⅰ(IGF-Ⅰ)were observed to elucidate their roles in the pathogenesis of leiomyoma.Methods Twenty one leiomyomal and six paired myometrial tissues from patients at the proliferative phase were included in the study.The mRNAlevels of ERα,ERβ and IGF-1 mRNA in leiomyoma and adjacent myometrium were determined by quantitative reverse transcriptase-polymerase chain reaction.Results All tissues showed a higher ERα expression level.The correlation between ERα mRNA and IGF-Ⅰ mRNA levels was significant(r=0.527,P=0.014).The correlation between ERβ mRNA and IGF-1mRNA levels was also positive,but the statics was not significant.In six paired leiomyoma and myometrium,the levels of ERα and ERβ mRNA exhibited no difference,but IGF-Ⅰ mRNA levels elavated significantly in leiomyoma when compared with paired myometrium(P<0.05).Conclusion The expression of IGF-Ⅰ mRNA increases in leiomyoma,and ERα mRNA is positively correlated with IGF-Ⅰ mRNA which implies that estrogen unregulate the IGF-Igene through ERα in leiomyoma.
