摘要 目的:探讨肝癌缺失基因-1(DLC-1)亚型(Isoform)1及2在人神经胶质瘤组织中的表达及其意义。方法:收集神经胶质瘤样本49例及对照脑组织14例,采用定量PCR检测DLC-1Isoform1、2的mRNA水平,比较两组差异。结果与结论:与对照脑组织比较,DLC-1Iso-form1在神经胶质瘤中低表达,而DLC-1Isoform2在神经胶质瘤中高表达,差异具有统计学意义(P<0.05);DLC-1Isoform1在Ⅱ,Ⅲ及Ⅳ级神经胶质瘤中的表达水平低于Ⅰ级神经胶质瘤,DLC-1Isoform2在I级神经胶质瘤中表达程度最高。DLC-1Isoform1在神经胶质瘤组织中低表达,而Isoform2高表达,提示DLC-1的功能可能具有组织特异性以及亚型特异性,DLC-1Isoform2是否可促进神经胶质瘤的生成,值得进一步行大样本研究。
