3、和MMP一2、MMP-9表达的影响方法:应用细胞培养技术培养HGC-27细胞,用不同浓度(O、10、20、40uM)的LY294002对细胞进行干预至不同的时间(20、40、60小时);CCK-8法检测细胞增殖;免疫细胞化学法检测p-Akt表达水平的改变;流式细胞仪(PI染色)检测细胞周期;半定量RT—PCR法检测删P一2、删P一9mRNA的表达情况。结果:LY294002作用于HGC一27细胞后:1.细胞增殖被抑制(P4、)和干预时间(P5、活化,能够抑制ⅦIlP一9的表达。关键词:LY294002胃癌细胞细胞增殖删P一2MMP一9AbstractObjective:ToinvestigatetherolesoftheP13K—。Aktsignalinthepr01iferationandMMP一2、MMP一9expressionofgastriccarcinomacellHGC一27,thespecificP13KinhibitorLY294002wastakentothecells,inhibitingtheactivationofth6、eP13K—Aktsignal.Methods:TheHGC一27cellSwereincubatedwithdifferentconcentrations(0,10,20and40laMseparately)ofLY294002fordifferenttimes(20,40and60hoursseparately):CCK一8wastakentotestthecellproliferation:PropidiumIodidedyingwastakentotestthedislocationofcell7、cycle:immunocytochemistorywastakentotesttheexpressionofp-Akt:semi—quantityRT—PCRwastakentotesttheexpressionsofmRNAofMMP一2andMMP一9.Results:WhentheHGC一27cellSweretreatedwithLY294002:1.thecellpr01iferationwasinhibited(P8、ffectofproliferationinhibitionwasincreasedwiththeconcentrions(P<0.05)ofLY294002andinterferingtimes(P
