Inhibiting enzyme common to all mammals shows anti-aging potential

Researchers have uncovered a new target in the quest to extend the lifespan of mammals. Inhibiting a common enzyme found in all mammals, including humans, has been shown to extend the lifespan of flies and worms, suggesting it could be a promising new mechanism for anti-aging therapies to target.

RNA polymerase III (Pol III) is an enzyme known to be essential for cell growth, and it is found withinin almost all cells across all mammals. Researchers from University College London, the University of Kent and the University of Groningen started examining the enzyme's involvement in aging after the immune-suppressing drug rapamycin, known to inhibit Pol III, was seen to extend the lifespan of several animal models including mice.

"Understandably, there's a lot of hype around drugs that extend lifespan and promote healthy aging but very little is known about how they work, which is fundamental knowledge," says study co-author Nazif Alic.

Pol III was inhibited using a variety of genetic techniques across several different model organisms, from flies and worms to yeast. These targets were chosen as they aren't closely related but, despite this, a lifespan extension of around 10 percent on average was seen across the experiments when Pol III activity was only modestly reduced in adult organisms.




Certainly holds some promise. So if one could get their hands on this stuff they could attempt it?

You know, any year that you add to your life is another full year of unexpected breakthroughs that might extend your lifespan even more.


So having said this, any gain, no matter how small it is, is very well worth it even if it is just 5% or 10% at the start.

Also if the 10% figure was replicated in humans (with our much longer lifespan) that's 8-10 years of extra life, and probably a slowdown in aging on the way, leading to people being healthier for longer.
