Abstract
Aging is inevitable processes which play a significant role in the development of various diseases, including cardiovascular diseases, neurodegenerative disorders, and cancers. The extension of lifespan and the improvement of age-related diseases can potentially be achieved by targeting evolutionarily conserved pathways and mechanisms through pharmacological interventions. Chrysophanol (Chr), a naturally occurring anthraquinone compound primarily derived from rhubarb of the Polygonaceae family, exhibits a wide range of pharmacological activities, including anti-cancer, anti-inflammatory, and anti-bacterial effects. However, its role in regulating aging remains unclear. In this study, we discovered that Chr extends both lifespan and healthspan in Caenorhabditis elegans by activating the DAF-2/DAF-16 insulin signaling pathway. Furthermore, we observed that Chr promoted longevity in natural aging mice, doxorubicin-induced aging mice, and transgenic mice through the conserved Insulin/IGF-1 signaling pathway. Additionally, Chr also influenced senescence-associated secretory phenotypes (SASPs) and enhanced the expression of antioxidant genes, contributing to delayed aging. These findings highlight that Chr exerts anti-aging effects from C. elegans to mammals via the evolutionarily conserved Insulin/IGF-1 signaling pathway, positioning Chr as a promising candidate for the prevention and treatment of aging and age-related diseases.
期刊介绍:
Free Radical Biology and Medicine is a leading journal in the field of redox biology, which is the study of the role of reactive oxygen species (ROS) and other oxidizing agents in biological systems. The journal serves as a premier forum for publishing innovative and groundbreaking research that explores the redox biology of health and disease, covering a wide range of topics and disciplines. Free Radical Biology and Medicine also commissions Special Issues that highlight recent advances in both basic and clinical research, with a particular emphasis on the mechanisms underlying altered metabolism and redox signaling. These Special Issues aim to provide a focused platform for the latest research in the field, fostering collaboration and knowledge exchange among researchers and clinicians.
