1、摘要目地:通过观察Notch-1,NF.r,B和p-eatenin在口腔鳞状细胞癌中地表达情况,探讨Notch-1,NF.r,B及Wnt/p.catenin信号传导系统在口腔鳞状细胞癌发生、发展过程中地作用。方法g应用免疫组织化学染色方法检测了58例口腔鳞状细胞癌组织及30例癌周组织中Notch-1,NF.r,B和D.catenin蛋白表达情况并分析其与临床病理特征地关系。结果:ONotch.1,NF.r,B蛋白在口腔鳞状细胞癌组织中地表达明显高于在癌周组织,并且两者染色积分间地差异具有显著性(P<
2、0.05)。两种蛋白地表达水平与患者地年龄、性别、肿瘤原发部位和组织学分级之间无相关性,但是与肿瘤TNM分期以及有无淋巴结转移密切相关(P<0.05)。②在58例口腔鳞状细胞癌组织中p.catenin异位表达37例(63.79%),p-catenin异位表达与肿瘤TNM分期(P3、P<0.05);Notch-1表达和13-catenin异位表达有显著关联性(P<0.05);而NF.1cB蛋白表达和p.catenin异位表达未见明显相关性(P>0.05)。结论:Notch.1,NF.迎高表达和B.catenin异位表达在口腔鳞状细胞癌中属常见现象,并且三者表达情况均与肿瘤TNM分期以及有无淋巴结转移密切相关。Notch.1表达分别和NF.r,B表达及p.catenin异位表达及膜表达缺失有显著关联性,但NF.r,B表达和p.catenin异位表达无明显相关性。关键词:口腔鳞状细4、胞癌;Notch-l;NF-KB;p-eatenin;表达AbstractOHective:ToinvestigatetheexpressionofNotch.1,NF.rBand13-catenininoralsquamouscellCarcinoma,anddiscusstheirassociationandrelationshipwiththeclinicopathologicalfeatures.Methods:TheexpressionofNotch一1,NF.r.Band13-caten5、inwereanalysedin58oralsquamouscellcarcinomasamplesand30morphologicallynormaltissuesadjacenttothecarcinomasusingimmunohistochemistry.Results:Notch-1andNF-lcBproteinweredemontratedtobeup.regulatedinmostoraIsquamouseellcarcinomasamplesthaninnormaltissuesb6、yimmunohistochemistry.AndthedifferenceinweightedscoresbetweenthesetwogroupWassignificant(P<0.O1).AlthoughtherewerenocorrelationbetweenexpressionofNotch.1,NF.rd3proteinandsometumourclinicalparameters(e.g.age,gender,tumoursiteandhistologicalgrade),theexp7、ressionofNotch-1,NF一1cBproteinwassignificantlyassociatedwithtumourclinicalstage(尺0。01)andlymphnodemetastasis衅O.05).Abnormall3.cateninexpressionWasdemontratedtobeup-regulatedinmostoralsquamouscellcarcinomasamplesthaninnormaltissuesbyimmunohistochemistry8、.,andthedifferenceinweightedscoresbetweenthesetwogroupWassignificant(/'<0.01).Therewerenocorrelationbetweenexpressionofabnormall3·cateninexpressionandsometurnoutclinicalparameters(e.g.age,gender,tumoursiteandhistologicalgrade),whilethee
