1、青岛大学硕士学位论文靶向survivin的siRNA联合5--FU转染抑制肝细胞株HepG2增殖的研究姓名:冯晶晶申请学位级别:硕士专业:肿瘤学指导教师:雷炜20120602靶向survivin的siRNA联合5-FU转染抑制肝细胞株HepG2增殖的研究摘要目的:研究靶向survivin的(小分子干扰RNA)siRNA和(氟尿嘧啶)5-FU联用对肝癌细胞HepG2的增殖抑制及凋亡的影响。方法:将HepG2细胞分为空白对照组、阴性对照组、5一FU处理组、siVA转染组、5一FU+siRNA转染组。转染采用脂质体法。RT-PCR法检测HepG2细胞survivinmRNA转录水平
2、;MTT法检测靶向survivin的siRNA和5-FU对HepG2细胞增殖的抑制作用;流式细胞术检测HepG2细胞凋亡情况。结果:空白对照组、阴性对照组、5-FU处理组survivinmRNA表达无明显变化(P>O.05),siRNA转染组、5一FU+siRNA转染组survivinmRNA表达明显下降(F=280.326,q=4.72’7.34,P3、13568.68,q=110.47"--327.16,P4、nti-proliferationeffectof(smallinterferenceRNA)siRNAagainstsurvivincombinedwith(.f1....u....o....r..o....u...r...a...c..—i.1)5-FUonhumanlivercancercelllineHepG2.Methods:HepG2cellscultureswe他dividedintof.vegroups:blankcontrolgroup,negativecontrolgroup,5-FUgroup,siRNA-survivingroup,siRNA-surv5、ivin+5一FUgroup.LipofectamineTM2000wasusedtotransfectHepG2cell.TheexpressionofsurvivinmRNAwasdetectedbyRT-PCR.TheeffectsoncellproliferationandapoptosiswereanalyzedbyMTrassayandflowcytometryrespectively.Results:TheexperimentofRT-PCRshowedthattheexpressionofsurvivinmRNAinsiRNA-survivingroupand6、siRNA-survivin+5一FUgroupwerelowerthanthatinothergroups(p<0.05),butitslevelsinblankcontrolgroup,negativecontrolgroupand5-FUgrouphadnosignificantchangeQ>o.05).TheMTTassayindicatedthattheantiproliferationrateofsiRNA-survivin+5一FUgroupwas51.38%±1.35.TheantiproliferationrateofthisgroupWashighert7、hanthatinanyothergroup(p<0.05).FlowcytometryWasindicatedthattheapoptosisrateofsiRNA-survivin+5-FUgroupWashigherthananyothergroup(p
