摘要 目的探讨心肌素(myocardin)、核转录因子(NF-κB)及类固醇激素受体共活化因子3(SRC-3)在子宫平滑肌瘤形成中的作用机制。方法采用荧光定量PCR技术检测22例子宫平滑肌瘤患者肌瘤组织与对应正常肌层组织中myocardin、NF-κB及SRC-3 mRNA的表达情况。结果肌瘤与对应正常肌层均有myocardin、NF-κB及SRC-3 mRNA表达。与正常肌层组织相比,肌瘤组织中myocardin的相对表达量降低(P<0.05),而NF-κB与SRC-3的相对表达量增高(P<0.05)。这三个基因的表达与患者的年龄、肌瘤的病理学类型、数量及是否变性无显著差异(P>0.05)。结论 myocardin对子宫平滑肌瘤的发生有一定抑制作用,而NF-κB与SRC-3可能协同促进子宫平滑肌瘤的发生。
