1、重庆医科大学硕士学位论文TCF4在病理性瘢痕中的表达及意义姓名:宋鹏宇申请学位级别:硕士专业:外科学指导教师:薛斌201205TCF4在病理性瘢痕中的表达及意义摘要目的:通过检测病理性瘢痕组织中T细胞因子4(TcF4)和转化生长因子(TGF’0)的表达并探讨TCF4在病理性瘢痕中的作用机制。方法:将收集到的临床标本分为三组,A组为正常皮肤,B组为增生性瘢痕,C组为瘢痕疙瘩;以正常皮肤为对照组,采用免疫组织化学检测各组中TCF4及TGF—B蛋白的表达水平、采用逆转录聚合酶链反应(RT—PCR)检测TCF4mRNA的表达水平、采用westernB10t方法检测TCF4蛋白的表达情况。结
2、果:TCF4免疫组织化学,在B组和c组中表达为强阳性,在A组中表达为弱阳性,B组、C组与A组相比较差异具有统计学意义(P3、80±0.0307),B组(O.3865±0.0412),较对照组A组(O.1835±0.0192)明显上调(P4、estigatether01eofTCF4inthepa.thologicalmechanismofscar.Methods:T11eclillicalspecimenswerediVidedinto缸eegroups,GroupA仃omnornlalskin,GroupBfromhypenrophicscar,GroupCfromkeloid.ThecontrolgroupisgroupA.ThechangesofTCF4andTG_F—pgeneweredetectedwithRT—PCRandTCF4andTC求-pproteinweredetectedwithimmunoh5、istochemicalandWestemblot.m熔pIts:TheeXpressionofTCF4withImmunohistochemicalingroupBandgroupCwasstronglypositiVe,weaklypositiVeexpressioningroupA.AndtheexpressionofT(讯-pwithImmunohistochemicalingroupBandgroupCwaspositive,andnegatiVeexpressioningroupA.111eresultshowstatisticallysi弘incantdifferen6、cecomparedGroupBandgroupCtogroupAinTCF4(P7、heproteinexpressionofTCF4inhypenrophicscarandkeloidweresignmcanthi曲erthanmoseinnormalskins,andshowstatisticallysigni6cantdif亿rencecomparedC(O.6780土O.0307)andgroupB(O.3865土O.0412)toA(O.1835土0.0192)(P<0.05)andCtoB(P
