What it means

Researchers have identified a protein called whose levels decline with age in the brain. In experiments on older mice, restoring Menin rejuvenated aging brain cells, making them function more like young cells. The work points to a potential target for therapies aimed at reversing brain aging.

Accuracy & sourcesGrounded

The claim comes from a Science Daily press release reporting on a peer-reviewed study, likely published in a scientific journal such as Nature or Cell. The press release is a secondary account close to the original research, but the specific details about Menin's role have not been independently confirmed without reading the full paper. The search results support that the study involves Menin and aging reversal in mice.
