1、华中卅技土学同许医学院嘎士学挂论文肺癌组织中端粒酶的表达及意义华中科技大学同济医学院附属协和医院呼吸内科研究生李向阳导师白明教授摘要目的:探讨端粒酶活性在肺癌组织及肺良性疾病组织中的表达,并探讨端粒酶与肺癌组织学类型、淋巴结转移及肿瘤临床分期间的相关性。方法:采用TRAP—PCR—ELISA定量法及原位杂交定性方法,检测44例手术切除标本端粒酶活性及hTERT的表达,其中包括30例肺癌组织和14例良性病变及正常肺组织。结果:(1)TRAP—_PCR—EUsA检测端粒酶活性肺癌组织明显高于肺良性病变和正常肺组织(P2、例肺良性病变及正常组织中阳性率为714%(1/14),两者差异具有显著性(P005)。(5)端粒酶活性,hTERT阳性率在不同时期肺鳞癌中表达差异无显著性(P>o05)。(6)30例肺癌组织中22例(733%),同时表达端粒酶和hTERT,端粒酶活性与hTERT呈正相关(P<005)。结论:1、端粒酶可能参与了肺癌的发生、发展。2、端粒酶可作为病理学鉴别肺癌与良性病变的一个指标。3、端粒酶可作为判断肺3、癌淋巴结转移的辅助指标。关键词:端粒酶,hTERT,T&AP—PCR-_ELISA,原位杂交;肺癌华中卅杖土学闾许匹学院硕士学位论文——-_-——————————-_-———_——————-———-————————,—————-————_———————————_●—-———————————————————————一ExpressionmadSignificanceofTelomeraseinLungCancerAbstractObjectiveTostudytheactivityoftelomeraseinlungcancertissuesandlungbenigndiseaseandnorm4、altissues,andtoexplorethecorrelationoftelomerasewithhistologictumorclassification,lymphnodemetastasisandclinicalstage.Methods:TheactivityoftelomereasewasdetectedbyTRAP—PCR~EUSA。andtheexpressionofhTERTmRNAWaSexaminedusinginsituhybridizationtechniquesinsamplefrom44patienstswithsurgicallresected,includ5、ing30lungcancersamplesand14benigndiseaseor’’normal”samples.Resluts:(1)Thelevelsoftelomeraseactivityinprimarylungcancertisusseswassignificantlyhigherthanthatinbenignlunglesionsornormaltissues(P<001).(2)ThepositiverateofhTERTmR_NAinlungcancertissuewas83.8%.andthepositiverateofhTERTmRNAinbenigndiseaseo6、rnormaltisussewas714%,therewasapositivesignificantdifferencebetweenthem伊7、sionofhTERTmRNAbetweenSquamouscellcarcinomaandAdenocarcinoma(P>O.05)(5)TherewerenosignificantlydifferenceamongdifferentclinicalstageintheleveloftetomeraseandtheexpressionofhTERTmRNA.(P>005)(6)Telomera
