Summary

Story summary

Baylor College of Medicine researchers find metformin acts directly in the brain by targeting Rap1 in the ventromedial hypothalamus.
In mice, removing Rap1 eliminates metformin's effect on diabetes-like conditions.
The findings show metformin's mechanism extends beyond the liver and gut, enabling potential targeted treatments.
Future human studies are needed to confirm results and explore brain aging and lifespan effects.
