1、青岛大学硕士学位论文瞬时性受体电位通道香草酸亚型6在子痫前期胎盘中的表达及意义姓名:李燕婷申请学位级别:硕士专业:妇产科学指导教师:纪向虹20120602瞬时性受体电位通道香草酸亚型6在子痫前期胎盘中的表达及意义摘要目的分析不同孕周子痫前期患者的胎盘组织中瞬时性受体电位通道香草酸亚型6(transientreceptorpotentialvanilloid6,TRPV6)的表达;探讨TRPV6在子痫前期发病机制中的作用。方法选取健康孕妇(对照组),早发型子痫前期(早发组)和晚发型子痫前期(晚发组)的孕妇的胎盘组织各15例,采用逆转录一聚合酶链反应(Rever
2、setranscriptionPCR,RT-PCR)检测各组胎盘组织中TRPV6mRNA的表达,并运用免疫组织化学方法分析各组胎盘组织中TRPV6蛋白的分布和表达。结果({)RT-PCR研究结果表明,TRPV6mRNA在早发组胎盘组织中的表达为0.45±0.07,显著低于晚发组(O.60±0.06)以及对照组(0.64±0.08)在胎盘组织中的表达,差异有统计学意义(PO.05)。(墓)TRPV6蛋白在对照组、早发组以及晚发组胎盘组织中均有表达,主要表达于滋养层细胞的胞
3、膜、胞浆;早发组的阳性表达率为53.3%,显著低于晚发组(93.3%)以及对照组(100%)的胎盘组织,差异有统计学意义(P0.05)。结论人胎盘组织中表达TRPV6基因:TRPV6基因在早发型子痫前期胎盘组织中呈低表达;TRPV6基因的低表达可能与早发型子痫前期的发病机制相关。硕士研究生:李燕婷(妇产科学)指导教师:纪向虹教授关键词:瞬时性受体电位通道香草酸亚型6;胎盘;子痫前期;凋亡ExpressionandSignificanceofTRPV6ofplacentainearlyonsetpr
