Transcript

取小鼠原代小脑颗粒神经元的培养物。

加入含有过氧化氢、活性氧或ROS的培养基,并短暂孵育。

过氧化氢扩散到细胞中并转化为高反应性自由基。

这些自由基诱导脂质过氧化,损害细胞膜的完整性。

此外,自由基会引起细胞蛋白质的氧化修饰,从而损害其功能。

此外,它们还会诱导 DNA 断裂,导致基因组不稳定。

自由基还会对细胞内细胞器(包括线粒体)造成氧化损伤。

作为响应,受损的线粒体释放细胞色素 c,与细胞凋亡蛋白酶激活因子-1 结合,触发凋亡体形成以及半胱天冬酶前 9 转化为活性半胱天冬酶-9。

半胱天冬酶 9 激活刽子手半胱天冬酶,进一步切割细胞蛋白并导致细胞凋亡性神经元死亡。

用

新鲜的、不含过氧化氢的培养基替换培养基,以停止信号级联。

对于ROS诱导的细胞死亡,用75至100微摩尔的过氧化氢处理神经元5分钟。五分钟后,将其从平行培养物切换到条件培养基。

由于过氧化氢的不稳定性,必须将浓度优化到24小时后诱导50%至70%细胞死亡的水平。该浓度通常在 75 至 100 微摩尔之间。
