1、MicroRNA-29b在卵巢上皮性癌中的表达及临床意义’摘要目的探讨微小RNA-29b(MicroRNA-29b,miR一29b)在卵巢上皮性癌组织中的表达及意义。方法采用实时荧光定量聚合酶链反应(Quantitativerealtimepolymerasechainreaction,qRT-PCR)和免疫组化PV-6000二步法在60例卵巢上皮性癌,15例卵巢良性肿瘤及15例正常卵巢组织中检测MicroRNA一29b及血管内皮细胞生长因子(Vascularendotheliagrowthfactor,VEG
2、F)蛋白的表达,探讨miR-29b的表达与临床病理特征及预后的关系,研究与VEGF蛋白表达的相关性。结果1、卵巢上皮性癌组织中miR-29b的表达量显著低于正常卵巢及卵巢良性肿瘤组织(p<0.05)。2、miR-29b的表达量与FIGO分期、淋巴结转移及腹水产生相关(pO.05)。Ⅲ~Ⅳ期和淋巴结转移组的表达量分别低于I~II期和无淋巴结转移组(p3、n—Meier法比较生存曲线表明,miR-29b表达量低者术后生存时间短(P4、展,具有潜在的辅助诊断及预后意义,VEGF蛋白可能为miR-29b发挥作用的重要靶蛋白。硕士研究生孙双双(妇产科学)指导教师王黎明副教授关键词:MicroRNA一29b;卵巢肿瘤;实时荧光定量聚合酶链反应;免疫组化;靶蛋白;VEGFExpressionofMicroRNA-29bintheEpithelianOvarianCanceranditsclinicalsignificanceAbstractobiectiveToinvestigatetheexpressionofmiR-29bintheEpithel5、ianOvarianCanceranditsclinicalsignificance.MethodTheexpressionofmiR-29bandproteinlevelsofVEGFi1190ovarianspecim-髓s(including15normal,15benignand60malignant)weredetected、j~ri也Real-timePCRandimmunohistochemistry.CorrelationsofmiR-29bexpressiontothepathoclinica6、lcharacteristicsandprognosisofepithelialovariancancerwereanalyzed.11圮relevancebetweentheexpressionsofmiR-29bandVEGFproteinWaSanalyzed.Result1、neexpressionofmiR-29bWaSsignificantlydown-regulatedinpatients诵tllovariancarcinomacomparedtothoseinovarianbeIli朗tumor7、sandnormalcontrols.2、miR一29bexpressioninclinicalstageⅢ~Ⅳandinthegroupwithlymphnodemetastasisweresignificantlydown-regulatedcomparedtothoseinstageI~IIandinthegroupwithoutlymphnodemetastasisrespectively;hydroperitoneumWaSaSsociate-dwithlowexpressionofmiR-29b(p8、
