2、蒿琥酯对细胞增殖的影响,比色法检测细胞培养上清中乳酸脱氢酶(LDH)活性,酶消化法测定羟脯氨酸(HvP)含量,westernblotting法测定青蒿琥酯对HSCs内KLF一6蛋白表达的影响。结果:与对照组相比,青蒿琥酯能抑制肝星状细胞Lx一2的增殖(P<0.O1),且呈剂量一效应和时间一效应关系;青蒿琥酯各浓度组LDH活性与对照组比较,无显著性差异(尸>0.05);青蒿琥酯能降低肝星状细胞Lx一2中Hyp含量(P<0.O1),且呈剂量一效应关系,并能降低KLF6蛋白的表达(P3、原的生成以及KLF6蛋白的表达减少,进而抑制肝纤维化的发生。关键词青蒿琥酯;肝星状细胞;Kruppel样因子6;肝纤维化中图分类号R96文献标志码AEfectsofartesunateoncellproliferation,collaginggeneratingandKLF6expressioninhepaticstellatecellsZHANGXiao—yan,MAShu-jing,XUYa-jie,FANGBu—wu(DepartmentofPharmacology,TianjinMedicalUniversity,Tianjin300070,China)Ab4、stract0bjective:ToexploretheeffectofartesunateontheproliferationofLX一2cellandtounderstandtheinitiatoryanti-fibrogenicmechanismsofartesunate.Methods:HepaticstellatecellsfHSCs)LX-2weredividedintocontrolgroupandartesunategroupswithdifferentconcentrations.Theinhibitionofcellproliferationwa5、sdeterminedbyMTTcolorimetricassay.ThecontentofLDHwasdeterminedbyusingeolorimetricmethodwhilethecontentofhydroxyproline(Hyp)wasdeterminedbycolorimetricmethod.TheWesternblottingwasusedforthedetectionoftheexpressionofKLF-6proteininHSCsLX-2.Results:Theartesunatehadaninhibitioneffectoncellp6、roliferationfP<0.011withdoseandtime—effectrelationships;theactivityofLDHinsupernatanthadnostatisticalsignificancecomparedwithcontrolgroup(尸>0.05).ThecontentofHypwasgraduallydecreasedcomparedwithcontrolgroup<0.01)withdose-effectrelationship.TheexpressionofKLF6proteinwasdecreased7、dose-dependentmanner.Conclusion:ArtesunatecouldmarkedlyinhibittheproliferationofHSCsLX一2:ThemechanismmaybeassociatedwithsuppressingtheexpressionofcollagenandthusdecreasingtheexpressionofKLF6protein.Keywordsartesunate;hepaticstellatecells;KLF6;hepaticfibrosis肝纤维化是由于多种致病因素导致的细胞外疟作用强,并具
