Telomerase Molecule

For many scientists who know about such things, the question isn’t whether the first person to live forever has been born, but how old they are.

The basis for this belief is that, if a person can survive the next 20 or 30 years, then breakthroughs in biotechnology will easily allow them to extend their lifespan – not to mention their quality of life – to 125 years. From that point, the advances will keep coming to allow the prolonging of life indefinitely. One of the first steps towards such a reality has just been announced by a group of researchers who have discovered the first compound that activates an enzyme called telomerase in the human body.

“Clock of aging”

A region of repetitive DNA at the end of a chromosome called a telomere, which protects the end of the chromosome from deterioration, is thought to be the “clock of aging” contained within the human body. Many scientists believe that the limit on lifespan and decline in health is imposed by the gradual shortening of our telomeres that occurs with every cell division. It has been repeatedly demonstrated that a human cell that does not undergo telomere shortening will divide indefinitely and is, by all available measurements, immortal.

Now researchers at Sierra Sciences, in collaboration with colleagues at TA Sciences, Geron Corporation, PhysioAge, and the Spanish National Cancer Research Center (CNIO), have discovered the first compound that activates telomerase – an enzyme that lengthens telomeres – in the human body, potentially opening the door to arresting or even reversing the aging process.

TA-65

The compound, a natural product derived nutraceutical known as TA-65, was shown to lengthen the shortest telomeres in humans, potentially extending human lifespan and healthspan. Telomerase activation is thought to be a keystone of future regenerative medicine and a necessary condition for clinical immortality.

Although TA-65 is probably too weak to completely arrest the aging process, it is the first telomerase activator recognized as safe for human use.

“We are on the cusp of curing aging,” said William Andrews, Ph.D., co-author of this study and President and CEO of Sierra Sciences, LLC. “TA-65 is going to go down in history as the first supplement you can take that doesn’t merely extend your life a few years by improving your health, but actually affects the underlying mechanisms of aging. Better telomerase inducers will be developed in the coming years, but TA-65 is the first of a whole new family of telomerase-activating therapies that could eventually keep us young and healthy forever.”
