Although multifactorial, mitochondrial dysfunction and oxidative stress have been proposed to be the driving forces of ageing. Peroxisome proliferator-activated receptor γ coactivator α (PGC-1α) is a transcriptional coactivator central to various metabolic functions, of which mitochondrial biogenesis is the most prominent function. Inducible by various stimuli, including nutrient limitations, PGC-1α is a molecule of interest in the maintenance of mitochondrial function and, therefore, the prevention of degenerative diseases. This review involves a literature search for articles retrieved from PubMed using PGC-1α, ageing, and dietary restriction as keywords. Dietary restriction has been shown to promote tissue-specific PGC-1α expression. Both dietary restriction and PGC-1α upregulation have been shown to prolong the lifespans of both lower and higher-level organisms; the incidence of non-communicable diseases also decreased in fasting mammals. In conclusion, dietary interventions may delay ageing by regulating healthy mitochondria in various organs, presenting the possibility of a new primary prevention for many age-related diseases.","PeriodicalId":11008,"journal":{"name":"Current aging science","volume":"5 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140721045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential of polyphenols\u0000in controlling skin aging has been the subject of much investigation throughout the\u0000years. Due to their complex molecular pathways, polyphenols, a broad class of bioactive substances\u0000present in large quantities in plants, have emerged as attractive candidates for skin anti-aging\u0000therapies. This review aims to provide a comprehensive overview of the molecular mechanisms\u0000through which polyphenols exert their anti-aging effects on the skin. Various chemical\u0000mechanisms contribute to reducing skin aging signs and maintaining a vibrant appearance. These\u0000mechanisms include UV protection, moisturization, hydration, stimulation of collagen synthesis,\u0000antioxidant activity, and anti-inflammatory actions. These mechanisms work together to reduce\u0000signs of aging and keep the skin looking youthful. Polyphenols, with their antioxidant properties,\u0000are particularly noteworthy. They can neutralize free radicals, lessening oxidative stress that might\u0000otherwise cause collagen breakdown and DNA damage. The anti-inflammatory effects of polyphenols\u0000are explored, focusing on their ability to suppress pro-inflammatory cytokines and enzymes,\u0000thereby alleviating inflammation and its detrimental effects on the skin.
