- Paper Abstract
- Nutrition intervention has emerged as a potential strategy to delay aging and promote healthy longevity. Citri Reticulatae Semen (CRS) has diverse beneficial effects and has been used for thousands of years to treat pain. However, the health benefits of CRS in prolonging health span and improving aging-related diseases and the exact mechanisms remain poorly characterized. In this study, Caenorhabditis elegans (C. elegans) was used as a model organism to study the antiaging and health span promoting activities of 75% ethanol extract of CRS (CRSE). The results showed that treatment with CRSE at 1 000 μg/mL significantly extended the life span of worms by 18.93% without detriment to health span and fitness, as evidenced by the delayed aging-related phenotypes and increased body length and width, and reproductive output. In addition, CRSE treatment enhanced the ability of resistance to heat, oxidative, and pathogenic bacterial stress. Consistently, heat shock proteins and antioxidant enzyme-related and pathogenesis-related genes were up-regulated by CRSE treatment. Furthermore, CRSE supplementation also improved α-synuclein, 6-OHDA, and polyQ40-induced pathologies in transgenic C. elegans models of Parkinson's disease and Huntington's disease. The mechanistic study demonstrated that CRSE induced autophagy in worms, while the RNAi knockdown of 4 key autophagy-related genes, including lgg-1, bec-1, vps-34, and unc-51, remarkably abrogated the beneficial effects of CRSE on the extending of life span and health span and neuroprotection, demonstrating that CRSE exerts beneficial effects via autophagy induction in worms. Together, our current findings provide new insights into the practical application of CRS for the prevention of aging and aging-related diseases.
