Scientists at Imperial College London may have discovered a method to halt aging and prevent cancer. According to a recent study published in the journal *Nature*, this new anti-aging approach could potentially extend human lifespan by up to 25 percent.
The research team conducted experiments on mice and found that inhibiting a protein called interleukin-11 (IL-11) could prevent cancer, enhance metabolism, improve hearing and vision, and boost lung and muscle function. Additionally, it may help prevent hair greying and loss.
In their tests, treated mice lived an average of 155 weeks, compared to 120 weeks for the untreated ones.
“These findings are very exciting,” said Stuart Cook, a professor at the Medical Research Council Laboratory of Medical Science at Imperial College, as reported by the *Telegraph*. “The treated mice had fewer cancers and were free from the usual signs of aging and frailty. We also observed reduced muscle wasting and improved muscle strength. In other words, the old mice receiving anti-IL11 treatment were healthier.”
Potential for Human Application
Although this research was conducted on mice, scientists believe that the drug could have similar effects in elderly humans. The IL-11 gene, which humans inherited from fish millions of years ago, aids in limb regeneration in some species. While once useful, it is now deemed unnecessary in humans and is associated with tissue scarring, thickening, and inflammation, all of which contribute to diseases and aging.
Researchers theorized that suppressing IL-11 could prevent aging after observing significant increases in the protein during lab tests on animals.
Other Anti-Aging Advances
In addition to this discovery, other studies are also striving to enhance human life quality and delay aging. Researchers from Harvard Medical School and the Massachusetts Institute of Technology have developed a pill that can rejuvenate human cells. This breakthrough could eliminate the need for gene therapy to reverse aging, offering a single-pill solution to improve eyesight and treat age-related diseases.
