2、A表达的影响。将不同浓度的大豆球蛋白(O~5.0mg·mL)与肠上皮细胞共同培养24h后,检测跨上皮细胞电阻值并用实时荧光定量PCR方法研究OccludinmRNA表达的变化规律。结果表明,与对照组相比,除大豆球蛋白浓度为0.5mg·mL-1时无明显变化,其他各浓度跨上皮细胞电阻值和OccludinrnRNA相对表达量均呈显著下降趋势(P3、IPEC细胞;Occludin)实时荧光定量PCR中图分类号:$828;$811.2文献标志码:A文章编号:0366-6964(2013)08—1258—05EffectsofGlycininonOccludinmRNAExpressioninPigletIntestinalEpithelialCellsHANRui,ZHAOYuan”,PANLi,WANGYu-qiong,QINGui—xin,(1.CollegeofAnimalScienceandTechnology,JilinAgriculturalUniversity,Changchun1304、118,China;2.KeyLaboratoryofAnimalProduction&ProductQualityandSecurity,MinistryofEducation,JilinAgriculturalUniversity,Changchun130118,China)Abstract:ThisexperimentwasconductedtoevaluatetheeffectsofpurifiedGlycininontheper—meabilityandtheexpressionoftightjunctionproteinOccludinin5、pigletintestinalepithelialcells(IPEC).IPECwereculturedwithmediumsaddedwithGlycininbydifferentconcentrations(0—5.0mg·mL)for24h.MeasuringthemRNAexpressionofOccludinbyreal—timequantitativeFQI-PCRandthetransendothe1ialelectricalresistant(TEER).Theresultsshowedthat,com—paredwiththeco6、ntro1group,GlycinincoulddecreasetheTEERandtherelativeexpressionofOccludin(P<0.001)mRNAinpiglet,butithadnosignificanteffectattheconcentrationof0.5mg·mL~.TheseresultsindicatethatGlycinincanincreasethepermeabilityoftheepithelialcells,anddecreasetheOccludinmRNAexpression.Furthermore7、,thisstudyclarifythattheGly—cinindirectlyinducesintestinaldamagebydepressingintestinalepithelialcellsgrowthanddama—gingtheintegrityofintestinalcells.Keywords:Glycinin;piglets;IPECcell;Occludin;real—timefluorescentquantitativePCR大豆抗原蛋白能够引起动物肠道结构破坏和炎症反应的发生。大豆球蛋白是其中主要的抗原蛋白收稿日期:20128、—12—04基金项目:国家自然科学基金青年基金项目(31101719);省科技发展计划项目青年
