Mutations in cGAS May Boost DNA Repair and Longevity in Naked Mole-Rats
Intro: A Hidden Genetic Edge for Longevity Why do naked mole-rats live so long, especially when compared with other rodents? A new study points to a subtle molecular difference that may help explain their remarkable genome stability. Researchers have identified specific evolutionary mutations in the DNA sensor cGAS (cyclic GMP-AMP synthase) that appear to bolster…

Evolutionary mutation in cGAS enhances naked mole-rat DNA repair
Unlocking a Cellular Secret: cGAS and the Naked Mole-Rat’s Longevity The naked mole-rat, a small, wrinkled rodent native to East Africa, has long puzzled scientists with a lifespan approaching four decades—remarkably longer than similarly sized mammals. A new line of research suggests that a cellular protein known for signaling immune responses to DNA damage may…
