Summary
Researchers identified seven novel anti-aging peptides from microalgae, including Spirulina platensis. These peptides significantly extended the lifespan and improved the health span of Caenorhabditis elegans, offering potential for new anti-aging functional foods.
Area of Science:
- Gerontology and Biotechnology
- Marine Biology and Nutraceuticals
Background:
- Global population aging necessitates novel anti-aging compounds.
- Microalgae represent a sustainable protein source with underexplored anti-aging peptide potential.
Purpose of the Study:
- To rapidly identify and characterize anti-aging peptides from edible microalgae.
- To investigate the efficacy of microalgal peptides in extending lifespan and health span.
Main Methods:
- Utilized the Caenorhabditis elegans model for aging studies.
- Employed multi-target virtual screening for peptide discovery.
- Analyzed peptide effects on lifespan, health span, and stress resistance.
Main Results:
- Identified seven novel anti-aging peptides (WFP, YPF, VFGF, NFF, WLG, YFP, RLF) from Spirulina platensis and Dunaliella salina.
- These peptides extended C. elegans lifespan by up to 24.74%.
- Isomeric tripeptides YPF and YFP enhanced nematode health span and stress resistance.
Conclusions:
- Neutral protease hydrolysis is effective for generating anti-aging peptides from microalgae.
- Hydrophobic amino acids are crucial for the anti-aging activity of these peptides.
- This study provides a novel discovery approach for anti-aging peptides, supporting functional food and pharmaceutical development.
