AI Insight
Scientists have identified that declining levels of the brain protein Menin may contribute to aging processes in mice. When Menin levels were low, researchers observed increased inflammation, cognitive impairment, reduced bone density, and skin thinning. Experimentally restoring Menin levels reversed multiple age-related changes, and supplementation with the amino acid D-serine separately improved cognitive function.
Why it matters
This research identifies Menin as a potential therapeutic target for addressing age-related decline in humans. If the findings translate from mice to humans, interventions targeting Menin or D-serine pathways could help maintain cognitive function, bone health, and other physiological systems during aging.
Understand the Science
Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring Menin reversed several age-related changes, while the amino acid D-serine improved cognition, hinting at a potentially intriguing new target for healthy aging.
