Mitch protein switch makes human cells burn fats for energy, opening obesity research avenue

Weizmann Institute researchers showed that deleting MTCH2 (Mitch) in human cells triggers a hypermetabolic state: mitochondria burn more fuel, especially fats, while fat storage and fat-cell formation are reduced, shedding light on MTCH2 as a regulator of cellular energy and obesity—though translating this into safe human therapies will require extensive follow-up.
