2、mRNA水平,并筛选出可有效沉默GPC3基因的siRNA。将肝癌Huh.7细胞株分为实验组、未转染组及对照组,实验组导入GPC3.siRNA-1633转染Huh.7,其余两组不作处理。EdU实验检查三组细胞增殖率,划痕实验测定各组细胞迁移率,Transwell实验测定各组细胞侵袭能力。结果实验组GPC3。mRNA表达量及GPC3蛋白水平显著低于未转染组及对照组,差异有统计学意义(P3、转染48h后,实验组细胞增生率、迁移率及侵袭率显著低于未转染组及对照组,差异有统计学意义(P4、andinvasionabilitiesofhepatomaHuh-7cellLeiChangfiang,LiLei,LongHaocheng,Cheng,HuangJianbin.DepartmentofGeneralSurgery,theSecondAfiliatedHospitalofJianghanUniversity,Wuhan43005~ChinaCorresponding~lMhor-LongHaocheng,Email:changjiangOll8@163.eom【Abstrac5、t】ObjectiveToinvestigateeffectofHippopathwaytargetingGPC3ontheproliferation,migration,andinvasionabilitiesofhepatornaHuh一7cel1.MethodsWesternblotassayandRT-PCRwereusedtomeasurelivercancerHuh一7GPC3proteinexpressionlevelsindiferentHCCcelllinesinlogarit6、hmicgrowthphaseandGPC3mRNAlevels,andCanefectivelyfilteroutGPC3genesilencingsiRNA.ThehepatomaHuh-7celllinesdividedintotwogroups,non-transfectedgroupandthecontrolgroup,theexperimentgroupimportGPC3一siRNA·1633-transfectedHuh-7,donotdealwiththeothertwogro7、ups.EdUexperimentalexaminationofcellproliferationrateofthethreegroups,eachgroupwasdeterminedexperimentallyscratchmobility,Transwellexperimentaldeterminationofeachgroupcellinvasion.ResultsTheGPC3mRNAGPC3expressionandproteinlevelsweresignificantlylower8、thannon-transfectedgroupandthecontrolgroup,thediferencewasstatisticallysignificant(p
