通过抑制ATM上调Bim促进小脑颗粒神经元凋亡
【目的】研究抑制共济失调毛细血管扩张突变(ATM)蛋白对SD大鼠小脑颗粒神经元(CGN)凋亡的影响及机制。【方法】将原代培养7~8d的CGN分为25K组、5K组和ATM抑制组。分别应用含有25和5mmol/LKCl的培养基处理25K组和5K组,建立体外神经元存活和凋亡模型。在25K神经元存活模型中,应用ATM抑制剂KU-55933(10μmol/L,ATM抑制组)、KU-55933联合MithramycinA(1μmol/L,MMA组)或ChromomycinA3(0.3μmol/L,CMA3组)处理,用WesternBlot方法检测p-ATM、ATM、Bim、Caspase3的表达水平,用H...
