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.
