1、中文摘要S/_P一2基因在子宫内膜癌组织中的表达及其功能研究目的探讨SLP.2(stomatin.1ikeprotein一2)基因在子宫内膜癌组织中的表达及其在子宫内膜癌发生、发展中的作用。方法f1)用半定量R丁.PCR技术检测32例子宫内膜癌组织和28例正常子宫内膜组织中SLP.2mRNA基因的表达情况,并比较不同临床病理特征的子宫内膜癌组织中SLP一2mRNA的表达差异。f2)用人SLP.2基因的正义和反义真核表达载体,分别转染人子宫内膜癌细胞系HEC.1B,RT.PCR技术检测转染后SLP一2mRNA的表达情况,观察转染前后HEC.1B细
2、胞的形态变化,用四甲基偶氮唑蓝(MTT)法绘制细胞生长曲线,流式细胞仪检测细胞周期的变化。结果(1)SLP.2mRNA在子宫内膜癌组织中表达量(1.58±0.71)明显高于正常子宫内膜组织(O.69--+0.32),差异有统计学意义(JD3、,S期增高8.05%:反义载体则使SLP·2基因表达量减少50%,细胞生长变慢,G1期增高10.5%,S期减少9.8%。结论SLP.2基因在子宫内膜癌组织中表达上调,其可能直接或间接参与了子宫内膜癌细胞周期的调控,与子宫内膜癌发生、发展有一定关系。硕士研究生冯旺琴(妇产科学)指导教师戴淑真教授、崔竹梅副教授【关键词】子宫内膜肿瘤;SLP一2基因;RT—PCR;细胞转染英文摘要ExpressionandfunctionalstudyofSLP-2geneinendometrialcancerAbstractobjectiveTocharacter4、izethedifferentialexpressionofstomatin-likeprotein一2(SLP-2)inendometrialcanceGandtostudythepotentialroleinvolvedincarcinogenesisofhumanendometrialcancer.Methods(1)TheexpressionofSLP一2genein32casesofendometrialcancerand28casesofnormalendometrialtissuesWasexaminedbysemi-quanti5、tativereversetranscription-polymerasechainreaction(RT·PCR).AndtheSLP-2expressionWascomparedinendometrialcancertissueswithdifferentclinicopathologicaldata.(2)EukaryoticexpressionvectorsofsenseandantisenseSLP-2wereconstructedandtransfectedintoHEC-1Bcelllineusinglipofectaminere6、spectively.ThemorphologicalchangesofthecellWasobservedbyphasecontrastmicroscopy.Thecellgrowthwasdetectedbymethylthiazolyltetrazolium(MTT)assay,andthecellcyclewereanalyzedbyflowcytometry.Results(1)TheexpressionofSLP一2mRNAinendometrialcancertissues(1.58±0.71)Washigherthanthati7、nnormalendometrialtissues(0.69-+-0.32)(P(0.05).ThereWasnocorrelationbetweenup-regulatedSLP一2geneandclinical·surgicalstage,myometrialdepth,metastasisoflymphnodes,anddifferentiation(尸>0.05).(2)SenseandantisensehumanSLP·2constructsweretransfectedintoHEC-1Bcelllinerespectively.A8、fterbeingtransfectedwithsenseSLP-2,theexpressionofSLP-2mRNAWasincreasedbyab
