摘要 [目的]探讨基质金属蛋白酶-7、9(MMP-7、MMP-9)在妊娠滋养细胞疾病中的表达水平。[方法]采用免疫组织化学PV-6000法测定49例葡萄胎(其中8例发生恶变,列为葡萄胎恶变组),8例恶性滋养细胞肿瘤(其中6例侵蚀性葡萄胎,2例绒毛膜癌)和18例正常早孕绒毛组织MMP-7、MMP-9的蛋白表达量;用RT-PCR法测定其中的35例葡萄胎(其中6例发生恶变,列为葡萄胎恶变组)和18例正常早孕绒毛组织的MMP-7、MMP-9mRNA表达量。[结果]MMP-7、MMP-9的蛋白表达量在恶性滋养细胞肿瘤及葡萄胎恶变组中的表达分别高于正常绒毛和葡萄胎未恶变组(P<0.05);MMP-7、MMP-9mRNA表达量在三组中的表达无显著性差异(P>0.05)。[结论]MMP-7和MMP-9可能通过降解细胞外基质参与妊娠滋养细胞疾病的发生和发展。
