2、IHC)检测胎盘组织中LXR仅及SREBP—lc的mRNA和蛋白表达水平。结果RT-PCR和IHC结果显示正常妊娠组和轻、重度子痫前期组胎盘中LXR、SREBP—lc的mRNA和蛋白的表达均逐步升高,且差异有统计学意义(P3、著高于正常妊娠,重度子痫前期表达水平更高。关键词:子痫前期;肝x受体仅;胆固醇调节元件结合蛋白一1c;滋养层中图分类号:R714.24文献标志码:AExpressionandsignificanceofLXRctandSREBP—lcinplacentaofpre—eclampsia.L/0n—hua,MIAOXue—qin,HUJi_厂en,CHENLi—hong.DepartmentofObstetricsandGynecology,the£AffiliatedHospitalofFujianMedicalUniversity,Fuzhou3500054、,ChinaAbstract:ObjectiveToevaluatetheexpressionandcorrelationsofliverXreceptoralpha(LXR(x)anditstargetgenesterolregulatoryelement~bindingprotein~lc(SREBP—lc)inplacentaofpre—eclampsia(PE)andtheirsignificanceinPE.MethodsBetweenOctober2011andAugust2012intheFirstAfiliatedHospitalofFuj5、ianMedicalUniversityob—servedPEgroup30cases(mild14casesandsevere16cases)andnormalpregnancygroup30cases.ThelevelofmRNAandproteinofLXR(xandSREBP——lcwereanalyzedbyreversetranscription——polymerasechainreaction(RT——PCR)andimmunohistochemistryfIHC1intheplacenta.ResultsRT—PCRandIHCallsho6、wthattheexpressionsofmRNAandpro.teinofLXRc~andSREBP—lcincreasedgraduallywithsignificantlydifferentlevelsamongnormalpregnancy,mildpre—eclampsiaandseverepre—eclampsiagroups(P<0.O1orP<0.05).TherewerepositivecorelationsbetweentheexpressionofLXR(xmRNAandLXRc~protein(r=0.417,P<0.01).The7、rewerepositivecorelationsbetweentheexpressionofSREBP—lcmRNAandSREBP—lcprotein(r=0.611,P<0.O1).TherewerepositivecorrelationsbetweentheexpressionofLXR(xpro—teinandSREBP—lcprotein(r=0.602,P8、higherthanthatofnormalpregnancy,w
