Abstract
Aging is a highly complex process and one of the largest risk factors for many chronic diseases. Aronia melanocarpa (AM) is rich in bioactive phytochemicals with antioxidant, anti-inflammatory, and anticancer properties. However, little is known about its effects on aging. The objective of this study was to evaluate the effects of AM extract on lifespan and health-span using Caenorhabditis elegans as a representative model. The mechanisms of its effects were explored using transcriptomics and untargeted metabolomics. Results showed that the lifespan of C. elegans was significantly extended by 22.2% after high-dose AM treatment. AM improved the behavior and physiological functions of C. elegans by increasing the pharyngeal pumping rate, decreasing lipofuscin accumulation and the reactive oxygen species level, enhancing resistance to oxidative stress, and increasing the activities of superoxide dismutase and catalase. Transcriptome analysis showed that the pmk-1 gene (mitogen-activated protein kinase 1), which is involved in the MAPK signaling pathway, was the gene with the largest fold change after AM intervention. However, in the C. elegans pmk-1(km25) mutant, the beneficial effect of AM in improving nematode senescence disappeared. An untargeted metabolomics study showed that the levels of 4-hydroxyproline, rhamnose, and cysteine were increased after AM supplementation, and their extending effect on the lifespan and health-span of C. elegans were partly dependent on the pmk-1 gene. In conclusion, our results revealed that AM can promote the lifespan and health-span of C. elegans via the PMK-1 pathway, highlighting the potential of AM as a dietary supplement to delay aging.
