1、山西医科大学硕士学位论文Bcl-2、Bad蛋白表达与乳腺癌的相关性研究姓名:王晓薇申请学位级别:硕士专业:普通外科指导教师:郭炳麟2003.5.192003詹硬士学位论文摘要目的:探讨bcl.2、bad基因在乳腺癌前病变及其在癌组织中的表达,细胞凋亡调控基因在乳腺组织恶性转化进程中的作用,以及其在乳腺癌组织中的表达与ER、PR及淋巴结转移问的关系。方法:利用免疫组织化学染色sABc法,原位观察19例乳腺单纯性增生,20例乳腺非典型增生,48例乳腺癌组织中bcl一2、bad蛋白的表达以8例正常乳腺组织作对照。并同时检测4
2、8例乳腺癌组织中ER、PR的表达。结果:bcl一2在正常组和乳腺单纯性增生组100%表达,乳腺非典型增生组,乳腺癌组的表达率分别为85.oo%和58.33%,二组之间比较有显著性差异(x2=3_37,P3、化中起重要作用,并可能与乳腺癌细胞凋亡调节有关,同时其表达与雌激素的调节有密切关系。bcl一2蛋白表达与乳腺癌淋巴结转移有关。关键词:bcl一2、bad,乳腺癌恶性转化,细胞凋亡±!塑查竺!!!!!!圭竺竺竺兰英文摘要Researchonthecorrelationofgenesbcl.2andbadinbreastcarcinomaAbstractobjectiveTbdetemineapoptosisregulatinggenebcl一2andbadinmalignanttrallsfbnllationofbrea4、stcajlceraJlditsprecancerouslesions,andbcl一2andbadcorrelatingwithestrogenreceptor(ER)andprogesteronereceptor(PR),withlymphnodesmetastasisofbreastcanceLMethodsByimmunohistochemicalmethod,theexpressionofbcl-2aIldbadgenewereobservedin8casesofnormalbreasttissues19ca5、sesofbreasthyerplasia,20caSesofbreastatypical,48casesofbreastcancerinsitus,andtesttheexpressionofER,PRandbcl—2,badinthebreaStcanceLEightnornlalbrcasttissueswereusedcontr01.ResultsThebcl-2genewaslOO%positiveeXpressioninthe8casesofnomlalbreasttissuesatld19casesofh6、yprepl船ia.Astatisticallysignificationwasfoundbetweenpositiverate58.33%ofbcl—2inbreastcancera11d85.O%ofatypical(X2=3.37P7、r,respectively.Therewassignificantdiffcrencebetweenpos“iverateofbcl-2andbadineachgroup.(x2=23.05P8、haspositiverel砒ion、vimtheeXpressionofbcl一2aJldbad.Conclusionbcl一2andbadonc叩roteinplaysa11imponamtroleofbreaStcanceringro、vthanddevelopment,2竺!苎兰查竺———_三唑型!!竺竺兰竺查mayhav
