The secret of long life may be in a naked mole rat

The typical naked mole rat lives 25 to 30 years, during which it shows little decline in activity, bone health, reproductive capacity and cognitive ability. What is the secret to this East African rodent’s long, healthy life?

Scientists from the United States and Israel found a clue. From infancy to old age, naked mole rats are blessed with large amounts of a protein essential for normal brain function.

“Naked mole rats have the highest level of a growth factor called NRG-1 in the cerebellum. Its levels are sustained throughout their life, from development through adulthood,” said Yael Edrey, doctoral student at The University of Texas Health Science Center San Antonio’s Barshop Institute for Longevity and Aging Studies.
