Eat Less, Live More: Protein Key to Longevity
13 Oct
Summary
- A newly discovered protein can significantly extend fruit fly lifespans.
- Restricting food intake during the larval stage boosts longevity.
- This protein, Lsp2, plays a crucial role in controlling lifespan.
Scientists in Japan have identified a protein that significantly increases the lifespan of fruit flies. This discovery supports the idea that early-life dietary restrictions can promote longevity.
The research focused on fruit flies, chosen for their short life cycles, allowing for comprehensive study from birth to death. A team from Riken found that limiting food intake specifically during the larval stage, followed by normal adult feeding, resulted in a lifespan extension of approximately 20% for both male and female flies.
Further investigation pinpointed the protein Lsp2 as crucial. When this protein's function was inhibited through dietary restriction or genetic modification during the larval stage, lifespan increased by about 20%. This indicates Lsp2's direct role in regulating how long an organism lives.
While the findings are promising, lead researcher Fumiaki Obata noted that it is currently unclear if the same mechanisms apply to humans. However, he confirmed the existence of similar proteins in humans, suggesting potential avenues for future health-related research aimed at promoting human longevity.
