Naked mole-rats are fascinating creatures. They can live up to 37 years—much longer than most rodents. Have you ever wondered how they do it? Research suggests their secret lies in a special protein that helps fix damaged DNA, which is key to aging.
DNA damage happens to all living things. As cells accumulate this damage, our bodies function poorly over time. A team from Tongji University in China studied a protein called cGAS (cyclic GMP-AMP synthase). In most mammals, including humans, this protein can hinder DNA repair. However, in naked mole-rats, it operates differently.
The researchers compared the cGAS protein in naked mole-rats to that in humans and mice. They found four specific changes in the structure of this protein that enhance the mole-rat’s DNA repair abilities. By inserting this modified cGAS into human and mouse cells in the lab, they saw significant improvements in DNA repair and reduced signs of aging.
In another interesting experiment, scientists engineered fruit flies to produce the naked mole-rat’s cGAS. These modified flies lived about ten days longer than usual. In a further step, they used gene therapy to introduce the naked mole-rat cGAS into mice. These treated mice showed less frailty, less gray hair, and more healthy cells in their organs compared to untreated mice.
“This alteration allows naked mole-rat cGAS to stabilize the genome and slow down aging,” the researchers explained. While this might raise hopes for applying similar methods in humans, the journey is long. Yet, this targeted research opens doors for new therapies aimed at age-related diseases.
Interestingly, this research taps into a growing trend around longevity treatments. Updated information from various health sources shows an increasing interest in how to extend healthy lifespans. The quest for longevity reflects societal shifts, with many people eager to explore alternative methods for enhancing quality of life as they age.
In summary, the naked mole-rat gives us valuable insights into aging and health. Ongoing studies could one day transform how we approach age-related conditions. For more on the science behind their longevity, you can check the article in Science here.
