摘要
目的:探讨癫痫大鼠海马组织核转录因子κB(NF-κB)随时间的变化规律及聚腺苷二磷酸核糖聚合酶(PARP)抑制剂3-氨基苯甲酰胺(3-AB)对NF-κB及白细胞介素1β(IL-1β)、环氧化酶-2(COX-2)的调节作用。方法:应用Western blotting检测海藻氨酸致痫大鼠海马核蛋白中NF-κBp65在不同时点及3-AB干预癫痫大鼠后的表达;应用RT-PCR及Western blotting检测IL-1β、COX-2 mRNA和蛋白水平在3-AB干预前后的变化。结果:大鼠海马核蛋白内NF-κBp65在癫痫后2h开始增高(P<0.05),持续12h(P<0.05),24h后恢复至对照组水平;应用3-AB后,NF-κBp65在核蛋白中含量明显下降(P<0.05);癫痫发作6h海马组织内IL-1β、COX-2 mRNA和蛋白水平表达增高(P<0.05),3-AB干预显著降低IL-1β、COX-2 mRNA及蛋白的表达(P<0.05)。结论:癫痫发作可诱发海马组织NF-κB的核转位及IL-1β、COX-2的表达,3-AB能明显抑制癫痫诱发的NF-κB核转位及IL-1β、COX-2的表达。
