PY - 2014 DA - 2014/11/13 TI - Oleanolic Acid Enhances the Beneficial Effects of Preconditioning on PC12 Cells SP - 929854 VL - 2014 AB - Preconditioning triggers endogenous protection against subsequent exposure to higher concentrations of a neurotoxin. In this study, we investigated whether exposure to oleanolic acid (OA) enhances the protective effects of preconditioning on PC12 cells exposed to 6-hydroxydopamine (6-OHDA). A concentration response curve was constructed using 6-OHDA (50, 150, 300, and 600
μ.m)。实验由6组组成:未经处理的,OA,第1组:用6-OHDA治疗的细胞(50
μ.m)1小时,第2组:用6-OHDA处理的细胞(150
μ.m)1小时,第3组:用6-OHDA处理的细胞(50个
μ.m)通过6小时后6小时后持续30分钟(150
μ.m)30分钟,第4组:在第3组中处理的细胞,但在第二次6-OHDA治疗后立即接受OA。使用MTT和膜蛋白V染色试验评估细胞活力和凋亡比。在预处理细胞中,我们发现在暴露于6-OHDA(150时,细胞活力保持高
μ.m)。OA治疗增强了预处理的保护作用。同样,随着膜蛋白的凋亡试验,预处理保护细胞,并通过OA增强。因此,PC12细胞对6-OHDA浓度的预先曝光可以防止随后的6-OHDA和OA的有毒损伤增强这种保护。SN - 2090-8083 UR - https://doi.org/10.1155/2014/929854 Do - 10.1155/2014 / 929854 JF - 帕金森病PB - Hindwi Publishing CorporationKW - ER -
