Naked mole rats live three to ten times longer than common rats, and several studies have shown the subterranean creatures might hold clues to longer life in humans. A new study finds a protein that could offer some longevity clues.

Genetic analysis of naked mole rats finds concentrations the protein NRG-1, crucial to brain functioning, are higher in naked mole rats than in several other rodent species and remain high throughout their lifetimes. NRG-1 is concentrated in the cerebellum, the part of the brain important to motor control, the researchers explained in a statement.

The findings, announced today, are detailed in the journal Aging Cell.

Previous research has found that naked mole rats have more productive protein-producing machines than other creatures, and also have more efficient systems to clean up damage proteins.
