Scientists at the University of Rochester have made a groundbreaking discovery by successfully transferring a longevity gene from naked mole rats to mice, resulting in improved health and an extended lifespan for the mice. Naked mole rats are known for their unusually long lifespans and resistance to age-related diseases, making them an intriguing subject for scientific research.
The gene that was transferred is responsible for producing high molecular weight hyaluronic acid (HMW-HA), a compound that plays a crucial role in cellular repair and protection. Naked mole rats have approximately ten times more HMW-HA in their bodies compared to mice and humans. Previous research has revealed that HMW-HA is involved in the naked mole rats’ resistance to cancer.
In this study published in Nature, the team of researchers genetically modified mice to produce the naked mole rat version of the hyaluronan synthase 2 gene, which is responsible for producing HMW-HA. The mice with the transferred gene exhibited better protection against both spontaneous tumors and chemically induced skin cancer. They also displayed improved overall health and a longer lifespan compared to regular mice. As they aged, these mice experienced less inflammation, a common sign of aging, and maintained a healthier gut.
The researchers believe that HMW-HA’s ability to regulate the immune system is the key to its beneficial effects. They are now focused on further understanding the mechanisms behind these effects and exploring ways to apply them to humans. The team has identified molecules that slow down HMW-HA degradation and is currently testing them in pre-clinical trials.
This groundbreaking study provides proof that longevity mechanisms found in long-lived species can be utilized to improve the health and lifespan of other mammals. The successful transfer of the longevity gene from naked mole rats to mice opens up exciting possibilities for unraveling the secrets of aging and potentially extending human lifespan.
While more research is needed, the implications of this study are promising. Enhancing the production or slowing down the degradation of HMW-HA in humans could potentially lead to improved health and a longer lifespan, as demonstrated in the mice. The findings lay the foundation for future studies on the role of HMW-HA in reducing inflammation-related diseases in humans.
This research not only sheds light on the intricate mechanisms that contribute to longevity but also offers hope for human health and lifespan extension. By unlocking the secrets hidden within long-lived species like naked mole rats, scientists are one step closer to enhancing human lifespan and improving overall well-being.
