摘要:

目的: 探讨天麻及其主要活性成分天麻素对帕金森病的潜在治疗机制,重点分析其在细胞凋亡、氧化应激及磷脂酰肌醇-3-激酶(PI3K)/RAC丝氨酸/苏氨酸蛋白激酶(Akt)/丝氨酸/苏氨酸蛋白激酶mTOR(mTOR)信号通路中的作用。方法: 采用 6-羟基多巴胺(6-OHDA)诱导的PC12细胞损伤模型,通过体外实验评估天麻素对细胞凋亡、细胞内活性氧水平及PI3K/Akt/mTOR信号通路相关蛋白表达的影响。结果: 实验结果表明,天麻素可显著改善6-OHDA诱导的PC12细胞凋亡,并对PI3K信号通路活性产生调控作用。此外,天麻素能够有效降低细胞内活性氧水平,该作用不依赖于PI3K信号通路的调控。结论: 天麻素可能通过降低细胞内活性氧水平并调控 PI3K/Akt/mTOR 信号通路的活性,协同发挥神经保护作用,从而减轻6-OHDA诱导的细胞凋亡,为其在帕金森病防治中的应用提供实验依据。

Abstract:

AIM: To investigate the potential therapeutic mechanisms of Gastrodia elata and its main active component gastrodin (GSD) in Parkinson's disease (PD), focusing on apoptosis, oxidative stress, and the PI3K/Akt/mTOR signaling pathway. METHODS: A 6-hydroxydopamine (6-OHDA)-induced PC12 cell damage model was used to evaluate the effects of GSD on cell apoptosis, intracellular reactive oxygen species (ROS) levels, and the expression of PI3K/Akt/mTOR signaling pathway-related proteins in vitro. RESULTS: GSD significantly attenuated 6-OHDA-induced apoptosis in PC12 cells and modulated the activity of the PI3K signaling pathway. In addition, GSD effectively reduced intracellular ROS levels, and this effect was independent of PI3K pathway regulation. CONCLUSION: Gastrodin may exert neuroprotective effects by reducing intracellular ROS levels and modulating the PI3K/Akt/mTOR signaling pathway, thereby alleviating 6-OHDA-induced apoptosis in PC12 cells. These findings provide experimental evidence supporting the potential application of GSD in PD therapy.
