Transcriptomic Approaches to Investigate the Anti-Aging Effects of Blueberry Anthocyanins in a Caenorhabditis Elegans Aging Model
This study investigates the anti-aging effects of various concentrations of blueberry anthocyanins (BA) on the lifespan and health-related phenotypes of Caenorhabditis elegans. Blueberry anthocyanins were administered at concentrations of 50.0 μg/mL, 200.0 μg/mL, and 500.0 μg/mL, and their effects o...

| Summary: | This study investigates the anti-aging effects of various concentrations of blueberry anthocyanins (BA) on the lifespan and health-related phenotypes of Caenorhabditis elegans. Blueberry anthocyanins were administered at concentrations of 50.0 μg/mL, 200.0 μg/mL, and 500.0 μg/mL, and their effects on nematode lifespan, locomotion, pharyngeal pumping rate, and the accumulation of lipofuscin and reactive oxygen species (ROS) were examined. Transcriptomic analysis was conducted to explore the regulatory effects of BA on anti-aging molecular pathways and key genes in <i>C. elegans</i>. Results showed a significant, dose-dependent extension of lifespan, improvement in locomotion and pharyngeal pumping rate, and reduction in lipofuscin and ROS accumulation. Transcriptomic analysis revealed that BA activated anti-aging pathways such as FOXO, IIS, and PI3K/Akt, upregulating critical genes like <i>daf-16</i>. These findings highlight the potential of blueberry anthocyanins as promising anti-aging agents through multiple physiological and molecular mechanisms. |
