2、gmol/L),对照组培养液中不加芬维A胺,分别孵育48h后,采用MTT法检测芬维A胺对HepG2细胞增殖的影响,流式细胞仪分析细胞周期和凋亡率。结果芬维A胺能明显抑制HepG2细胞增殖,呈时间和剂量依赖性;芬维A胺处理H印G2细胞72h,可使Gcq3。期细胞比例升高,G、S期比例明显下降,凋亡率明显上升(P3、2—O3Efectoffenrefinideontheproliferationandapoptos~ofhumanfivercancereelillnehepG2.SH/Sheng-li,DAIXiao-hua,MAYa-mei,ZHOUHai-hua.DepartmentofGastroenterology,ZhongshanXiaolanPeopleHospital,Zhongshan52841~Guangdong,CHINA【Abstract】0bjectiveToinvestigatethedepressantefectsoffertretinide4、onhumanlivercancercelllineHepG2cellsvitro.MethodsHumanlivercarcinomalineHepG2cellswereculturedinvitro.TheHepG2cellsofthetestgroupwereincubatedinthemedium、7Iri血fertretinideatdiferentconcentrations(2.5ismoFL,5gmol/L,10~tmol/L,20gmol/L).nlecellsofthecontrolgroupwereincubatedinthemedium5、for48hours.MTTmethodwasusedtode.tecttheantiproliferativeratiooffenretinideOllHepG2cells,andfloweytometrywasappliedtoanalyzethecellcycleandapopmficratio.ResultsFertretinidecouldobviouslyinhibittheproliferationofHepG2cells,sho、ngtime—anddose-dependentefects.72hoursafter也eHepG2cellswer6、etreatedwithfenretinide,thepercentageofHepG2cellsinG0~GIperiodincreased,andthatinG2~MperiodandSperioddecreased,withtheaopototicratioofHepG2cellsin-creasedsignificantly(P<0.05).ConclusionFeuretinidecaninhibitproliferationandpromoteapoptosisofhumanlivercancercelllineHepG2cellsinvitro.7、【Keywords】Fenretinide;HumanlivercancercelllineHepG2;Cellproliferation;Apoptosis基金项目:2012中山市科技局立项课题(编号:20122A106)通讯作者:石胜利。E—mail:shishengli2004@163.cQm【16】WySSJM,AboukarshN,OparilS.Sensorydenervationofthekid—HTN—2Tria1):arandomisedcontrolledtrial[J】.Lancet,2010,neyattenuatesrenovascu8、larhypertensioninth
