Early-life dietary protein effects on adult translation and longevity in flies — a research article explaining the experimental approach and implications for developmental nutritional memory.
Key Takeaways
- Stable-isotope tracing showed larval dietary amino acids persist into early adulthood and incorporate into ribosomal proteins.
- Larval serum protein 2 (Lsp2) levels are durably downregulated by early-life protein restriction and modulate adult translational activity.
- Genetic silencing of Lsp2 reproduces the lifespan extension and reduced ribosomal-protein abundance seen after early-life protein restriction.
