2、Wnt5a重组蛋白体外刺激LX一2和Wnt5ashRNA病毒转染LX-2,以qRT-PCR、ELISA检测促炎细胞因子IL.1B、IL-6的水平变化。结果LPS及TNF.ot可显著刺激LX-2Wnt5a表达增加(P<0.05);Wnt5a重组蛋白可促进LX-2细胞IL-113、IL-6表达和分泌(P<0.05);Wnt5ashRNA转染LX一2后IL一1B、IL-6表达水平显著降低(P<0.05),ELISA发现Wnt5ashRNA转染组培养上清IL一1B、IL-6水平显著低于pLVX.NC—shRNA组与LX-2组(P3、SC促炎细胞因子IL一1B、IL-6的表达而参与肝纤维化进程。【关键词】Wnt5a;肝星状细胞;IL一1B;IL-6;肝纤维化Wnt5aincreasestheexpressionofproinflammatorycytokinesIL·1BandIL_6inhumanhepaticstel-latecellsDongShuang,WuChenming,HuJunwei,WangQinqin,JianYicheng,HeYi,ZhongJie,XiongWujun.DepartmentofHepatology,ShanghaiEastHospitalAff4、iliatedtoTongiiUniversity,Shanghai2ool2o.ChinaCorrespondingauthor:XiongWujun,Email:xiongwujun@126.con【Abstract1objectiveTostudytheeffectsofWnt5aontheexpressionofproinflammatorycyto.kinesIL一1BandIL-6inhumanhepaticstellatecellsanditspathogenicmechanisminliverfibrosis.Meth.odsTheexpr5、essionofWnt5aatmRNAandproteinlevelsinLPS—stimulatedandTNF—ot-stimulatedhumanhepaticstellatecelllineLX-2wereanalyzedbyquantitativerea1.timePCRandWesternblot.LX-2cellsweretreatedwithhumanrecombinantWnt5aproteinandtransfectedbylentiviruscarryingWnt5ashRNA.respectively.Theexpressionof6、proinflammatorycytokinesIL.1BandIL6intreatedcellswereexaminedbyqRT-PCRandELISA.ResultsL】)SandTNF—otenhancedtheexpressionofWnt5ainLX-2cellsfP<0.05).RecombinantWnt5aproteinsignificantlyincreasedtheexpressionandsecretionofIL.1BandIL-6(P7、s,theexpressionandsecretionofIL.1BandIL-6inpLVX.Wnt5a-shRNAtransfectedLX-2cellsweresignificantlydecreased(P<0.05.Conclu.sionWnt5amightparticipateintheprogressionofliverfibrosistbroughpromotingtheexpressionofproin-flammatorycytokinesIL一1BandIL-6inhepaticstellatecells.【Keywords】Wnt58、a;Hepaticstellatecell;IL一1B;IL-6;
