摘要 Objective:Toexploretheprobabilityofvascularendothelialgrowthfactor(VEGF)antisenseoligodeoxynucleotidesasadevelopingnewtherapeuticstrategyforglioma.Methods:VEGFproteinexpressionwasdetectedbyS-Pimmunohistochemicaltechnique.TumorcellapoptosiswasobservedbyTUNELmethod.Results:Comparedwithcontrol,VEGFproteinexpressionwasinhibitedbyantisenseoligodeoxynucleotidesinvitro.Andtheinhibitoryeffectsincreasedwiththeincreasingconcentration.VEGFpositiveratewas82.10%incontrolgroup,whilein2.5,5,10(mol/LAODNgroups,theywere70.00%,57.85%,53.20%respectively.Noinhibitioneffectwasfoundinthecelllinestreatedwithmissenseandsenseoligodeoxynucleotides.Invivo,antisenseoligodeoxy-nucleotidestherapyalsoinhibitedVEGFproteinexpressionandinducedtheincreaseofapoptotictumorcells.However,ithasnoeffectontumorcellproliferation.Conclusion:ItishopefulthatVEGFantisenseoligodeoxynucleotidesmaybeanewgenetherapymethodtogliomathroughitsantiangiogenesiseffectbyinhibitionofVEGF.
