2、rg一1表达改变显著影响细胞代谢和生长状态。本研究旨在探讨Arg—l在肝细胞癌(hepatocellularcarcinoma,HCC)组织中的表达,分析Arg一1与Hcc临床病理指标之间的相关性。方法:采用逆转录一聚合酶链式反应(reversetranscriptase—polymerasechainreaction,RT—PCR)、蛋白印迹法(Westernblot)检测3lfrJHCC及癌旁肝组织、12例正常肝组织中Arg一1mRNA及蛋白表达水平。采用组织芯片结合免疫组织化学法检~lJAr
3、g一1在158例HCC及癌旁组织中的表达,结合临床病理资料统计分析。结果:Arg一1mRNA~B蛋白表达水平在HCC组织中明显低于癌旁和正常肝组织(F=57.83、160.89,P均<0.01),且与HCC的分化程度相关(F=10.41、30.03,P均4、15,P<0.05)。Arg一1表达与HCC分化程度、血管侵犯、术后复发有关(/2=22.8459、10.2639、10.6368,P均5、.1007—3969.2014.06.007中图分类号:R735.7文献标志码:A文章编号:1007.3639(2014)06.0438.08Down-regulationofarginase-1expressionanditsclinicalsignificanceinhepatOcellularcarcinomaGUChun—yan,XIAOFeng,QIANZheng,SHAOJian—guo,QINGang,CHENLi(1.Depa~mentofPathology,AfiliatedNa6、ntongThirdHospitalofNantongUniversity,NantongJiangsu226006,China;2.DepartmentofGastroenterology,AfiliatedNantongThirdHospitalofNantongUniversity,NantongJiangsu226006,China;3.DepartmentofInfectiousDisease,AfiliatedNantongThirdHospitalofNantongUniversit7、y,NantongJiangsu226006,China;4.DepartmentofPathology,MedicalSchool,NantongUniversity,NantongJiangsu226001,China)Correspondenceto:CHENLiE—mail:bll@ntu.edu.caI-Abstract~Backgroundandpurpose:Arginase一1(Arg-1)isanenzymeinvolvedintheureacycle.Researchhassh8、ownthatchangedexpressionofArg-1playsai1importantroleinthecellularmetabolismandgrowth.ThepurposeofthisresearchwastoinvestigatetheexpressionofArg一1inhepatocellularcarcinoma(HCC)andtoanalyzeitscorrelationwithclinicopathologicalfeatures.Methods:Th
