1、重慶醫(yī)科大學碩士學位論文MicroRNA--134在難治性癲癇病人癲癇動物模型中的表達及意義姓名:楊小蘭申請學位級別:碩士專業(yè):神經病學指導教師:陳陽美201205重慶醫(yī)科大學碩士研究生學位論文MicroRNA.134在難治性癲癇病人及癲癇大鼠模型中的表達及意義摘要目的:研究MicroRNA.134及其相關信號通路中CREB及磷酸化CREB在難治性癲癇患者及氯化鋰一匹羅卡品癲癇大鼠模型中的表達,以探討MicroRNA.134、CREB及磷酸化CREB在難治性癲癇發(fā)病中的意義。方法:從已建立的癲癇腦庫中隨機抽取出12例難治性癲癇患者手術后的腦
2、組織和12例對照腦組織。40只SD大鼠被隨機分成8組,每組5只,其中7組注射氯化鋰一匹羅卡品,另l組作為對照組;選取癇性發(fā)作后6h,24h,72h,1w,2w,lm,2m的顳葉腦組織為研究對象,并和對照組比較。采用qRT-PCR、免疫組化和westernblot檢測MicroRNA一134、CREB及磷酸化CREB在人和大鼠腦組織的表達及變化規(guī)律。結果:在人腦組織中,MicroRNA.134在難治性癲癇患者腦組織中較對照組顯著降低(P3、1w、2w、2m(P<0.05)。CREB及p-CREB在人及大鼠腦組織中存在于神經元細胞核中,在難治性癲癇患者腦組織中含量較對照組顯著升高(尸4、芽生,導致癲癇腦組織中異常神經網絡的形成,從而導致癲癇反復發(fā)作,并發(fā)展為難治性癲癇。關鍵詞:MicroRNA.134;CREB;難治性癲癇重慶醫(yī)科大學碩士研究生學位論文EXPRESSIONandSIGNIFICANCEofMIR.134inPATIENTSWITHINTRACTABLEEPILEPSYandARATMoDELofEPILEPSABSTRACTPURPOSE:TheexpressionofmicroRNA一134(miR-134),CREBandp-CREBwereresearchedintemporallobefocifro5、mpatientswithintractableepilepsyandinhippocampusofexperimentalanimals.METHODS:Twelvetemporalneocortextissuefrompatientswithintractableepilepsy(IE)andtwelvehistologicalnormaltemporallobesfromcontrolswereselected.FortySprague-Dawley(SD)ratsweredividedrandomlyintoeightgroups,6、includingsevengroupswithepilepsyinducedbylithitun—pilocarpineachninistrationandonecontrolgroupwithoutepilepsy.Andthenhippocampaltissuesweretakenfromratsat6hours,24hours,72hours,1weeks,2weeks,lmonths,2monthsafterseizures,andfromcontrols.ExpressionofmiR一134,CREBandp-CREBwere7、assessedbyilnmunohistochemistry,westernblotandreal-timequantitativePCR.Results:Inhumanbraintissues,mir-134expressionofpatientswithintractableepilepsywassignificantlylowerthanthecontrols(P<0.05).Andmir-134expressionofepilepticratswasalsolowerthannonnalrats,especiallytheseep8、ilepticratsattimepointsof72hours,1weeks,2weeks,2monthsafterseizures(P<0.05).CREBandp-CREB
