摘要:
目的从凋亡与自噬的调控探讨补阳还五汤类方提取物对PC12细胞氧化应激模型的保护机制。方法以不同浓度H_2O_2刺激PC12细胞制备不同损伤程度的氧化应激模型,采用MTT法确定补阳还五汤类方提取物对氧化应激损伤初期和加剧期发挥保护作用的有效浓度,流式细胞术和TUNNEL法检测细胞凋亡情况,透射电镜和mRFP-GFP-LC3腺病毒双标法检测细胞自噬情况,蛋白质印迹法检测凋亡相关蛋白(Bcl-2和Bax)与自噬相关蛋白(Beclin1、LC3A和LC3B)的表达。结果分别以0.5、2.0 mmol/L H_2O_2处理PC12细胞制备氧化应激损伤的初期模型和加剧期模型;与对照组比较,模型组细胞凋亡率增加,自噬程度加剧,Bax/Bcl-2比例增加,Beclin...
摘要(英文):
Objective: To explore the underlying mechanism of Buyang Huanwu Decoction extracts on apoptosis and autophagy in PC12 cells model with oxidative stress injury. Methods: Different level oxidative stress injury models with H2O2 at various concentrations were established. The effective concentrations of Buyang Huanwu Decoction extracts were determined by MTT method in the initial stage and the intensifying period after oxidative stress injury. The apoptosis of PC12 cells were evaluated by FCM and TUNNEL, the autophagy situations were observed by T...
