1、内蒙古医学院硕士学位论文P27、CyclinD<,1>、PCNA在喉癌中的表达及其意义姓名:刘勇智申请学位级别:硕士专业:耳鼻咽喉科学指导教师:彭诗东;冀文茹2003.6.1中文摘要。目的研究P27,CyclinDl,PCNA基因在喉癌中的表达及意义。方法采用免疫组化S—P法,检测P27,CyclinDl,PCNA基因蛋白在94例喉鳞状细胞癌及对照的11例正常喉粘膜,25例喉息肉,及30例喉粘膜非典型增生中的表达。结果P27,CyclinDl,PCNA均定位子缅胞核,P27在喉鳞癌,喉粘膜非典型增生,喉息肉,喉正常粘膜中的阳性表达率分别为
2、:57.45%;66.67%;92%;100%(P<0.01),CyclinDl在上述各组中阳性表达率分别为:96.8%;96.67%;84%;27.27%(P<0.01)。PCNA在上述各组中的阳性表达率分别为:97.87%;83.33%;68%;36.36%;(P<0.01)。P27,CyclinDl,PCNA在喉鳞癌中的表达与临床分期,有无淋巴转移、位置、性别、年龄均无关(P>O.05)。P27在喉鳞癌中的表达与组织分化程度显著相关(P3、相关性(P0.05)。结论P27、CychllDl、PCNA可作为确定喉癌发生的参考指标。P27可作为判断喉癌恶性程度的参考指标,cycfinDl在喉癌发生发展过程中,是一个较早的分子事件,对喉癌的发展起重要作用。而PCNA是判断细胞增殖活性的重要指标。关键词喉鳞状细胞癌免疫组化细胞周期依赖激酶抑制因子P27细胞周期素D1增殖细胞核抗原oABSTRACTObjectiveTostudytheeXpresSionandtheirsigh讧icaneesofthecydill一dependent4、l【inaSeinhjbitor(p27b91)CyclinDlaJldproliferatillgceunuclearaJltigen(P(:NA),MethodS—Pimmullohistochemicalrnethod、ⅣasusedtostudytheexpressionS0fP27,CyclillDlandPCNAinlaDmgealcaIlcers.(94),dySplastic印it圭llia(30).Vocal∞rdp01yps(25)andnomlal印it}llia(11).Re-suIt①Immunoreactio璐5、t0P27clyclinDlandP(烈A、张reIocalizedinthenucleiofceⅡsInsquarnousceⅡcarcin嘲oflaryTⅨd辨币laStic印itllli恤l,v()cal“cord烈ypandnonllallepitllli呦.②ThepOsmeim砌lI】os乜iningratesofP27pIDteinwere57.45%,66.67%,92%,arldl00%H焉pectively(P6、(P<0.01)ajldPCNAproteinSwere97.87%,83.33%,68%,36.36%,respec-tively(P<0.01).③ThepositiveexpreSSionofP27.CycIir】DlandPCNAwerenotassociatedwithdiIlicalstages,Lynlphodemet芒IStasisa11ato缸1icsite。,sex,age(P>0.05).PositiveeXpreSsionofP:27wasassociatIed试th王listol晒一跚grades(P7、butCyclinDl,PCNAdidnot.TherewasnotstatisticallysignificantcOrreltionbe押eenP27、CyclinDlandP心丁A(P>O.05).c蛐clu—sio吣TheP27、CvclinDlandPCNAcanbeconSideredaStherefereIltialin.dicatorSfordefinir增genesisoflar)mgealcancer.P27caJlberegardedaSthein—dicatorofc011Side血19t啪orcdldiffere8、ntiation.CychnDlcaJlbea11earIym0I—lec妇eventinthecarcinogen鹧适ofLarytu(a11dplayani111p0】恤troleinme
