Abstract

The progressive loss of dopaminergic neurons in the midbrain is the hallmark of Parkinson's disease (PD). A newly emerging form of lytic cell death, ferroptosis, has been implicated in PD. However, it remains unclear in terms of PD-associated ferroptosis underlying causative genes and effective therapeutic approaches. This research explored the underlying mechanism of ferroptosis-related genes in PD. Here, Firstly, we found NOX1 associated with ferroptosis differently in PD patients by bioinformatics analysis. In vitro and in vivo models of PD were constructed to explore the underlying mechanism. qPCR, Western blot analysis, immunohistochemistry, immunofluorescence, Ferro orange, and BODIPY C11 were utilized to analyze the levels of ferroptosis. Transcriptomics sequencing was to investigate the downstream pathway and the analysis of immunoprecipitation to validate the upstream factor. In conclusion, NOX1 upregulation and activation of ferroptosis-related neurodegeneration, therefore, might be useful as a clinical therapeutic agent.

摘要

中脑中多巴胺能神经元的进行性丧失是帕金森病(PD)的标志。一种新出现的裂解细胞死亡形式,铁死亡,与 PD 有关。然而,与 PD 相关的铁死亡的潜在致病基因和有效治疗方法仍不清楚。本研究探讨了 PD 中铁死亡相关基因的潜在机制。在这里,首先,我们通过生物信息学分析发现,NOX1 在 PD 患者中与铁死亡的相关性不同。构建了 PD 的体外和体内模型,以探讨其潜在机制。利用 qPCR、Western blot 分析、免疫组织化学、免疫荧光、 Ferro orange 和 BODIPY C11 来分析铁死亡的水平。转录组测序用于研究下游途径,免疫沉淀分析用于验证上游因素。总之,NOX1 的上调和铁死亡相关神经退行性变的激活可能是一种有用的临床治疗剂。
