摘要 目的探讨曲古抑菌素A(TSA)对神经细胞神经型一氧化氮合酶(nNOS)蛋白表达水平及nNOS催化的一氧化氮(NO)合成的影响。方法以大鼠神经胶质瘤C6细胞为研究对象,应用Western印迹杂交方法检测TSA刺激对nNOS蛋白表达水平的影响;分别应用TSA、7-NI(nNOS特异性抑制剂)及二者联合作用细胞,应用DAF-2DA荧光染料检测NO合成水平的变化,从而分析TSA对nNOS催化的NO合成水平的作用。结果 TSA使C6细胞nNOS蛋白表达显著升高,达到对照的2.8倍(P<0.001);同时TSA的作用使nNOS催化的NO合成明显上升,为基础状态的3.5倍(P<0.001)。结论 TSA可上调C6细胞中nNOS蛋白及其催化的NO合成,这可能为TSA的临床应用提供一定的分子基础。
