- W766909541 abstract "目的:探讨磷脂酰肌醇-3激酶/Akt信号途径在体外培养神经干细胞存活、分化中的作用.方法:分为对照组、wortmannin组和LY294002组;免疫组化检测Nestin、NSE和S100的表达;TUNEL评价细胞凋亡率;Western Blotting检测磷酸化Akt、Caspase-9的表达.结果:随着wortmannin和LY294002浓度增大,细胞凋亡率逐渐增加.随着wortmannin和LY294002浓度增大,磷酸化Akt的表达逐渐减弱.高浓度时磷酸化的Caspase-9表达减弱.结论:神经干细胞存活依赖于PI3K/Akt途径的活化,其机制可能是PI3K/Akt活化后,促进了Caspase-9等蛋白的磷酸化,抑制了细胞凋亡事件的发生." @default.
