Abstract

Neurologic conditions including stroke, Alzheimer disease, Parkinson disease, and Huntington disease are leading causes of death and long-term disability in the United States, and efforts to develop novel therapeutics for these conditions have historically had poor success in translating from bench to bedside. Hypoxia-inducible factor (HIF)-1α mediates a broad, evolutionarily conserved, endogenous adaptive program to hypoxia, and manipulation of components of the HIF pathway is neuroprotective in a number of human neurological diseases and experimental models. In this review, we discuss molecular components of one aspect of hypoxic adaptation in detail and provide perspective on which targets within this pathway seem to be ripest for preventing and repairing neurodegeneration. Further, we highlight the role of HIF prolyl hydroxylases as emerging targets for the salutary effects of metal chelators on ferroptosis in vitro as well in animal models of neurological diseases.

摘要

神经学疾病包括中风、阿尔茨海默病、帕金森病和亨廷顿病,是美国主要的致死和致残原因,而开发这些疾病的新型治疗方法在从实验室到临床的转化过程中一直成效不佳。缺氧诱导因子(HIF)-1α介导了广泛的、进化上保守的、内源性的缺氧适应程序,并且在许多人类神经疾病和实验模型中,HIF 通路的成分的操纵具有神经保护作用。在这篇综述中,我们详细讨论了缺氧适应的一个方面的分子成分,并提供了关于该通路中哪些靶点似乎最适合预防和修复神经退行性变的观点。此外,我们还强调了 HIF 脯氨酰羟化酶作为金属螯合剂在体外和神经疾病动物模型中对铁死亡有益作用的新兴靶点的作用。
