Restoring Brain Protein Menin Reverses Aging Markers in Mice

Scientists have shown that lowering levels of the brain protein Menin drive aging in mice. In experiments, mice with reduced Menin displayed increased inflammation, cognitive decline, bone loss, and skin thinning. When researchers reintroduced Menin, many of these age‑related changes reversed, restoring healthier tissue and function. The study also tested the amino acid D‑serine, which further improved cognitive performance in the animals. The findings suggest that Menin and D‑serine could become new targets for interventions aimed at slowing or reversing aging processes. Researchers plan to investigate the mechanisms behind Menin’s protective effects and evaluate whether similar strategies can be applied to human aging. The work opens a promising avenue for developing therapies that promote healthy longevity.
