1、重庆医科大学硕士学位论文妊娠期肝内胆汁淤积症孕妇胎盘合体滋养细胞OATP8基因表达及意义研究姓名:李秋红申请学位级别:硕士专业:妇产科学指导教师:邵勇201205重庆医科大学硕士研究生学位论文妊娠期肝内胆汁淤积症孕妇胎盘合体滋养细胞OATP8基因表达及意义研究摘要目的:探讨有机阴离子转运多肽一8(0ATP8)在妊娠期肝内胆汁淤积症(ICP)孕妇胎盘组织中的表达及其意义。方法从重庆医科大学附属第一医院收集2010年9月一2011年3月期间分娩的16例ICP孕妇的胎盘绒毛组织,其中8例ICP轻度孕妇作为ICP轻度组,8例ICP重度孕妇作为ICP重度
2、组,同期分娩的8例正常晚期妊娠妇女胎盘组织作为对照组。用免疫组化链霉亲和素一生物素一过氧化物酶复合物法(sABc)检测胎盘组织中0ATP8蛋白定位表达,采用逆转录(RT)一PCR技术检测oATP8mRNA表达;采用蛋白印迹法检测0ATP8蛋白表达水平。结果(1)在对照组和IcP轻度组,0ATP8蛋白定位于胎盘合体滋养细胞膜上,着色较淡,呈淡棕色染色,着色部位主要在细胞膜;在ICP重度组,OATP8也主要定位在胎盘合体滋养细胞膜上,呈棕黑色浓染。(2)对照组、ICP轻度组及ICP重度组孕妇胎盘组织中0ATP8mRNA的表达水平分别为0.13±0.
3、01、O.21±0.02及0.32±0.04,ICP重度组的表达明显高于对照组和ICP轻度组,差异均有统计学意义(尺O.05);而IcP轻度组与正常对照组比较,差异有统计学意义(尸<0.05)。(3)对照组、ICP轻度组及重度组孕妇胎盘组织中0ATP8蛋白的表达水平分1重庆医科大学硕士研究生学位论文别为(0.58±0.05)、(O.82±O.07)及(1.02±0.10),ICP轻度组与ICP重度组比较,差异有统计学意义(尸4、0.05)。结论IcP孕妇胎盘合体滋养细胞0ATP8蛋白的表达水平上调,可能有助于胎盘对胆汁酸或胆红素的清除作用。[关键词]有机阴离子转运多肽一8;妊娠期肝内胆汁淤积症;胆红素;胎盘重庆医科大学硕士研究生学位论文EXPRESSIoNANDCLINICALSIGNIFICANCEoFoRGANICANIoNTRANSPORTINGPOLYPEPTIDES.8GENEINPLACENTASYNCYTlOTROPHOBLASToFINTRAHEPATICCHoLESTASISoFPREGNANCYABSTRACTobjectiVeToexploret5、heeXpressionandclinicalsignificanceof0rganicAnionTransportingPolypeptides-8(OATP8)geneonplacentaassociatedwithintrahepaticch01estasisofpregnancy(ICP)MethodsPlacentawerecollected舶mICPwomenwhodelivered仔omSeptenber20l0toMarch2011intheFirstA伍liatedHospitalofChongqingMedicalUniVe6、rsity,includingmildpre印antwomenasmildICPgroup(n28)andseVerepregllantwomenasseVereICP伊oup(n28).Then8healthypregnantwomenwhodeliVeredinthesamegestationalagewerechosenascontrolgroup.The10cationof0ATP8proteininplacentawasstudiedbyImmunohistochemicalSABcmethod,.OATP8mRNAleVelwasd7、eter玎mnedbyreVersetranscriptionpolymerasechainreaction(RT-PCR)techniqueandwestemblotquantifiedOATP8proteinexpressionleVel.5重庆医科大学硕士研究生学位论文Results(1)0ATP8waslocatedintheplacentalsyntrophoblasticCytomelnbraneofcontrol黟oLlpandmildICP黟oup,stainedlighttanandmainlyonthecytomembran8、e;insevereICPgroup,0ATP8alsolocatedinplacentalsyntrophoblasticcytomembranew
