摘要: 目的: 研究H2O2诱导PC12细胞的内质网应激损伤作用及原花青素对其预防作用。方法: H2O2 100 μmol/L 诱导PC12细胞损伤 18 h 复制阿尔茨海默病模型(AD),原花青素 40 mg/L、SB203580 10 μmol/L、Tempol 800 μmol/L 于造模前 30 min 预处理后,RT-PCR检测BiP/GRP-78 mRNA表达水平变化;流式细胞术检测细胞内反应氧产物(ROS)阳性细胞生成率,计算平均荧光强度。结果: H2O2 100 μmol/L 诱导PC12细胞损伤后BiP/GRP-78 mRNA表达量显著增高,ROS生成增加;原花青素 40 mg/L 可显著降低BiP/GRP-78 mRNA表达水平(P<0.01),减少细胞内ROS生成(P<0.01)。结论: 原花青素可减轻H2O2引起PC12细胞的内质网应激损伤。

Abstract: AIM: To study the protective effects of the proanthocyanidins on the endoplasmic reticulum stress in PC12 cells induced by H2O2. METHODS: The models of alzheimer ' s disease were established by treating PC12 cells with H2O2 (100 μmol/L)for 18 h.Before modeling for 30 minutes proanthocyanidins 40 mg/L, SB203580 10 μmol/L,Tempol 800 μmol/L were administrated respectively. The level of BiP/GRP-78 mRNA was detected by RT-PCR. The formation rate of reactive oxygen species(ROS)positive cells was detected with flow cytometry,the mean fluorecence was calculated. RESULTS: The level of BiP/GRP-78 mRNA and the formation rate of ROS were decreased in PC12 cells treated with H2O2; the level of BiP/GRP-78 mRNA and the formation rate of ROS were decreased(P<0.01) with proanthocyanidins treatment(40 mg/L)in PC12 cells treated with H2O2. CONCLUSION: Proanthocyanidins can ameliorate endoplasmic reticulum stress in PC12 induced bywith H2O2.
