摘要 目的探讨糖皮质激素诱导的蛋白激酶1(SGK1)在大鼠海马神经元细胞中缺血再灌注中的保护作用。方法将海马神经元细胞根据氧糖剥夺(脑缺血)诱导时间不同分为正常海马神经元细胞组,氧糖剥夺诱导120 min组、氧糖剥夺诱导120 min后正常恢复10 min组、氧糖剥夺诱导120 min后正常恢复30 min组和氧糖剥夺诱导120 min后正常恢复60 min组。采用Annexin V-FITC/PI流式细胞术对样品进行检测,区分实验样本中正常、坏死、凋亡细胞。结果随着氧糖剥夺(脑缺血)时间的延长而神经元细胞凋亡的数量呈现不断增加的趋势;而随着氧糖剥夺(脑缺血)时间的延长,SGK1在蛋白水平的表达出现不断下降的趋势;和对照组相比其神经元细胞凋亡的数量明显减少;SGK1蛋白的过表达受到抑制。结论SGK1可以有效减少氧糖剥夺SD大鼠海马神经元细胞的凋亡,而SGK1调控神经元细胞凋亡的模式是通过PI3K/Akt/GSK3β信号通路来介导。
