Scientists claim to have achieved the “Holy Grail” in groundbreaking studies and reverse aging.
Who wants to live forever?
In a one-of-a-kind study, researchers from Tel Aviv University and Shamir Medical Center used a form of oxygen therapy to reverse two key indicators of biological aging: telomere length and the accumulation of senescent cells. Scientists claim to have successfully reversed the biological aging process in a group of seniors. If so, they have potentially opened a multi-pound business – after all, who wouldn’t want to be younger?
Science explained
As the human body ages, it experiences shortening of telomeres – the protective caps found at the ends of chromosomes – and an increase in old, malfunctioning senescent cells. A clinical study involving 35 adults over the age of 64 sought to understand if a method called hyperbaric oxygen therapy could prevent these two hallmarks of the aging process from deteriorating. The subjects were placed in a pressurized chamber and treated with pure oxygen for 90 minutes per day, five days per week for a period of three months.
By the end of the trial, the scientists reported that the participants’ telomeres had increased in length by an average of 20%, while their senescent cells had been reduced by up to 37%. This is the equivalent of how their bodies were at the cellular level 25 years ago, the researchers reported.
“Since telomere shortening is considered the ‘Holy Grail’ of the biology of aging, many pharmacological and environmental interventions have been extensively explored in hopes of enabling telomere lengthening,” said Shai Efrati, a professor at the Faculty of Medicine and Sagol School of Neuroscience at Tel Aviv University and co-author of the study.
“The significant improvement in telomere length shown during and after these unique HBOT protocols provides the scientific community with a new basis for understanding that aging can, in fact, be targeted and reversed at the basic cellular biological level.” It is the latest in a series of radical anti-aging treatments, which seek to increase life expectancy and even make people look and feel younger.
