Stressing a worm’s mitochondria at a key time in early development is known to improve their metabolic health and extend lifespan. Researchers discovered what’s behind this: enzymes that tag DNA and make epigenetic changes that affect the expression of mitochondrial genes long into adulthood, making the mitochondria more efficient. In long-lived mice, these same enzymes are up-regulated, implying that they play a key role in boosting metabolic function in mammals as well.
