2、达,探讨在双暴露情况下catenin、PTEN与HCC发生、发展的关系。方法根据HBV与AFB1的暴露情况,将108例肝细胞癌手术切除研究对象分为4组,A组:HBV(+)/AFB1(+)48例;B组:HBV(+)/AFB1(一)27例;C组:HBV(一)/AFB1(+)19例;D组:HBV(一)/AFB1(一)14例。同时收集正常肝组织者2O例,分别来自肝外伤、肝血管瘤、肝移植供体等手术切除标本作为正常对照组。采用逆转录一PCR(RT—PCR)法检测catenin基因与PTEN基因的mRNA表达情况,分别对各组的表达情况进行
3、比较。结果RT-PCR显示,~catenin基因mRNA的半定量平均灰度值A组(1.13士0.14)、C组(1.16士0.18)分别与D组(1.01±0.13)相比,差异有统计学意义(P<0.05),此外,A、B(1.06-4-0.18)、C、D组与正常对照组比较,差异均有统计学意义(P<0.001)。PTEN基因mRNA的半定量平均灰度值A组(0.54士0.13)、B组(0.59±0.16)分别与C组(0.97±0.16)及D组(O.92±0.13)相比,差异有统计学意义(P4、,差异有统计学意义(P<0.05)。结论catenin基因的高表达率可能与AFB1高暴露有关,P咂N基因的失活与HBV高感染率有关。关键词:癌,肝细胞;乙肝肝炎;黄曲霉素B1;catenin基因;PTEN基因;mRNA表达doi:10.3969/j.issn.1671-8348.2014.14.。。1文献标识码:A文章编号:1671-8348(2O14)14-1681—03ThemRNAexpressionofcateninandP珏NinHepat0cellularcarcinomaexposedt0hepatitisBv5、irusandaflatoxinB1ChenDPg,QLunan。,PengTao。,LuoGuorong,LiLequn2zk(1.GraduateSchoolofGuangxiMedicalUniversity,Nanning。Guangxi530021,China;2.DepartmentofHepatobiliarySurgery,TumorHospitalofGuangxiMedicalUniversity,Nanning,Guangxi530021,China;3.DepartmentofHP户n£06ZnrSu6、rgery,FirstAffiliatedHospitalofGuangxiMedicalUniversity,Nanning,Guangxi530021,China;4.SchoolofBasicInedicine,GuangxiMedicalUniversity,Nanning,Guangxi530021,China)Abstract:ObjectiveToinvestigatethemRNAexpressionof~-cateninandPTENinhepatocellularcarcinomaexposedtohep7、a—titisBvirus(HBV)andaflatoxinB1(AFB1).Methods108HCCscamefromdifferentdistrictsofGuangxiprovincewerelabeledasfourcategoriesbasedontheirbiomarkersofHBVandAFB1exposure.GroupA:HBV(+)/AFB1(+),48cases,groupB:HBV(+)/AFB1(一),27cases,groupC:HBV(一)/AFB1(+),19cases,groupD:HB8、V(一)/AFB1(一),14cases.Andnormalhepatictissuefrom20casesofhepatichemangioma,liverresectionandlivertransplantdonorwerechosenasnormalcontrolgroup.And
