1、上皮性卵巢癌组织中ER13与p—ERKl/2的表达及临床意义中文摘要目的:探讨上皮性卵巢癌组织中雌激素受体B(ERB)、磷酸化细胞外信号调控蛋白激酶1,2(p-ERKl/2)的表达及两者的相关性。方法:应用逆转录聚合酶链反应(RT-PCR)技术和免疫组织化学SP法分别从mRNA及蛋白水平检测70例上皮性卵巢癌、24例卵巢良性肿瘤、24例正常卵巢组织中ERB和p-ERKl/2的表达,并分析其与临床病理特征之间的关系及两者的相关性。结果:(1)卵巢癌组织中ERBmRNA相对表达水平(O.3764±O.9826)显著低于卵巢良性肿瘤(0.4900±0。3742)及正常卵巢组织(0.4980±0。0
2、434)(尸3、RKl/2蛋白表达呈负相关(严一0.282,P<0.05)结论:上皮性卵巢癌组织中ERB表达的降低和ERKl/2的过高表达可能在卵巢癌发生、发展和侵袭中有协同作用,这可能为卵巢癌的临床预后和内分泌治疗提供新的靶点和方向。硕士研究生:葛书霞(妇产科学)导师:陈爱平教授关键词:卵巢恶性肿瘤;雌激素受体;ERKI/2信号转导通路;磷酸化细胞外信号调控激酶1,2;免疫组织化学方法;ExpressionofER[iandp-ERKl/2inepithelialovariancancerABSTRACTObjective:Toinvestigatetheexpressionandtherelations4、hipbetweenestrogenreceptorp(ERl3)andphosphorylatedextracellularsignal.regulatedproteinkinase1/2(p·ERKl/2)inepithelialovariancancer.Methods:ExpressionofERB.p-ERK1/2mRNAandproteinlevelweredetectedbyRT-PCRandimmunohistochemistryrespectivelyin70epithelialovariancancers,24benignovariantumorsand24normalo5、variantissues.Theirrelationshipandclinicalpathologicalcharacterswasalsoanalyzed.Results:(1)TheexpressionofERpmRNAinpatientswithepithelialovariancancers(0.3764+0.9826)wassignificantlylowerthanthatinbenignovariantumors(0.4900士0.3742)andnormalcontrols(0.4980士0.0434)(P<0.05).TheexpressionofERpmRNAWascl6、oselyrelatedtopathologicgradesandlymphnodemetastasis(P<0.05).ThepositiveratesofER13proteininovariancarcinomaWaswellconsistentwithcharacteristicsofovariancarcinomaandexpressionlevelofitsmRNA.TheexpressionofERK1/2mRNAinovariancancer(0.6007士0.1554、0.6951士1.3694)Wassignificantlyhigherthanthatinbenignov7、ariantumors(0.3575士0.0479、0.5125士0.0411)andnormalcontrols(0.3027士0.1024、0.5431士0.0811)(P
