- W952550166 abstract "目的探讨Ndfip1对MPP＋（1-甲基-4-苯基-1,2,3,6-四氢吡啶）诱导的帕金森病（Pkarkinson＇s disease,PD）细胞模型（人神经母细胞瘤SH-SY5Y细胞）的保护作用。方法利用已建立好的Ndfip1内源性表达（野生型,WT-SY5Y）、过表达（4HT诱导,SY5Y-N）、显性负表达（显性负载体,SY5Y-D）及抑制表达（Ndfip1 shRNA载体瞬时转染,SY5Y-I）四种不同SH-SY5Y细胞模型,采用MPP＋诱导上述细胞形成PD细胞模型,利用MTT法在酶联免疫检测仪上测量OD490吸光值以计算细胞的存活率,采用Annexin V凋亡检测试剂盒和流式细胞仪测定细胞的凋亡率。结果 0.3 mmol/L浓度的MPP＋可降低WT-SY5Y细胞存活率,增加细胞凋亡率,其他细胞模型的细胞存活率及细胞凋亡率也与此类似;当加入4HT时,SY5Y-N细胞中因Ndfip1大量表达可明显增加细胞存活率,抑制细胞凋亡率,与WT-SY5Y相比,差异有统计学意义（P〈0.05）;而此时SY5Y-D和SY5Y-I细胞中因Ndfip1的表达被抑制不能明显增加细胞存活率,降低细胞死亡率（P〉0.05）。结论 Ndfip1对MPP＋诱导的PD细胞模型具有明显的神经保护作用及抗凋亡作用,研究结果有助于对PD发病机制的研究,为PD的临床治疗开辟了新的思路。" @default.
