摘要 目的:探讨肺癌患者糖基化磷脂酰肌醇特异性磷脂酶D(GPI-PLD)的活性变化,为肺癌患者预后判断提供依据。方法:利用具有糖基化磷脂酰肌醇(GPI)结构的胎盘碱性磷酸酶(PLAP)做底物,通过TX-114分相,定量检测外周血单个核细胞和血浆中GPI-PLD活性,并采用荧光定量PCR检测外周血单个核细胞中GPI-PLDmRNA水平,分析其表达量与肺癌之间的关系。结果:肺癌患者外周血单个核细胞和血浆中GPI-PLD酶活性分别为(24.15±2.33)%和(29.71±1.32)%,明显低于正常人(P<0.001),且肺癌患者单个核细胞GPI-PLD活性仅为其血浆中酶活性水平的81.29%,两者之间差异有显著性(P<0.05);肺癌患者外周血单个核细胞中GPI-PLD mRNA表达平均值为0.44±0.11,明显低于正常人(P<0.001)。结论:GPI-PLD在肺癌患者中的活性及表达明显降低,有可能作为肺癌预后判断的指标之一。
