摘要

过氧化物酶体增殖体激活受体(PPAR)-γ共激活因子(PGC)-1α,与多种转录因子相互作用,涉及广泛的生物反应。它已被确定为许多线粒体成分转录调控的关键角色。PGC1-α的活性在多个水平上受到调控,如基因表达、转录、转录后和翻译后修饰。本综述的目的是强调支持PGC1-α-通过转录和翻译后修饰介导的调节的数据。我们总结了通过磷酸化(AMPK、p38 MAPK、Akt和GSK3β)、乙酰化(GCN5、p300和SRCC)和泛素化(e3 -泛素连接酶)调控PGC1-α的机制。此外,本文还对PGC1-α的多结构域结构及其在脑中的表达以及PGC1-α介导的线粒体功能的重要性进行了综述。线粒体功能障碍和能量代谢受损是神经退行性疾病的关键特征,如阿尔茨海默氏症、亨廷顿氏症、帕金森氏症、肌萎缩侧索硬化症和多发性硬化症。它与PGC1-α表达或活性降低有关,导致线粒体动力学维持不平衡。在此背景下,我们还提供了PGC1-α在神经退行性疾病发病机制中的含义的全面概述。总的来说,PGC1-α作为治疗的潜在靶点,可以减少与神经退行性疾病相关的线粒体功能障碍,并有助于神经保护。

Regulation of PPAR-γ coactivator-1α and its implication in mitochondrial function and neurodegenerative diseases
Peroxisome proliferator-activated receptor (PPAR)-γ coactivator (PGC)-1α, interacts with numerous transcription factors implicated in a wide spectrum of biological responses. It has been identified as a key player in the transcriptional regulation of many mitochondrial components. The activity of PGC1-α is regulated at multiple levels, such as gene expression, transcriptional, post-transcriptional, and post-translational modification. The purpose of this review is to highlight the data supporting PGC1-α-mediated regulation by transcriptional and post-translational modification. We summarize the mechanisms involved in PGC1-α regulation by phosphorylation (AMPK, p38 MAPK, Akt, and GSK3β), acetylation (GCN5, p300, and SRCC), and ubiquitination (E3-ubiquitin ligase). Moreover, the review focuses on the multidomain structure of PGC1-α, its expression in the brain, and the importance of PGC1-α-mediated mitochondrial functions.
Mitochondrial dysfunction and impaired energy metabolism are key characteristics of neurodegenerative diseases like Alzheimer's, Huntington's, Parkinson's, amyotrophic lateral sclerosis, and multiple sclerosis. It is associated with reduced PGC1-α expression or activity, resulting in an imbalance in the maintenance of mitochondrial dynamics. In this backdrop, we additionally provide a comprehensive overview of the implication of PGC1-α in the pathogenesis of neurodegenerative disease. Overall, PGC1-α acts as a potential target for therapies to reduce mitochondrial dysfunction associated with neurodegenerative diseases and aid in neuroprotection.

期刊介绍: With the rise in average human life expectancy, the impact of ageing and age-related diseases on our society has become increasingly significant. Ageing research is now a focal point for numerous laboratories, encompassing leaders in genetics, molecular and cellular biology, biochemistry, and behavior. Ageing Research Reviews (ARR) serves as a cornerstone in this field, addressing emerging trends. ARR aims to fill a substantial gap by providing critical reviews and viewpoints on evolving discoveries concerning the mechanisms of ageing and age-related diseases. The rapid progress in understanding the mechanisms controlling cellular proliferation, differentiation, and survival is unveiling new insights into the regulation of ageing. From telomerase to stem cells, and from energy to oxyradical metabolism, we are witnessing an exciting era in the multidisciplinary field of ageing research. The journal explores the cellular and molecular foundations of interventions that extend lifespan, such as caloric restriction. It identifies the underpinnings of manipulations that extend lifespan, shedding light on novel approaches for preventing age-related diseases. ARR publishes articles on focused topics selected from the expansive field of ageing research, with a particular emphasis on the cellular and molecular mechanisms of the aging process. This includes age-related diseases like cancer, cardiovascular disease, diabetes, and neurodegenerative disorders. The journal also covers applications of basic ageing research to lifespan extension and disease prevention, offering a comprehensive platform for advancing our understanding of this critical field.
