Israeli scientists claim to ‘partially reverse’ biological aging for first time in history

The development is the latest in a series of radical anti-aging treatments that seek to increase life expectancy and make people look and feel younger.

  • Scientists in Israel claim to have partially reversed cellular aging using a controversial method of oxygen therapy.
  • The study participants were placed in a pressurized chamber and were given 90-minute pure oxygen sessions, five days a week for three months.

Researchers claim to have successfully reversed the aging process in a group of elderly adults using a somewhat controversial treatment.

In the first study of its kind, scientists from the Shamir Medical Center and Tel Aviv University used oxygen therapy to reverse two significant biological aging indicators – Telomere length and senescent cell accumulation.

As humans get older, their bodies experience a decrease of telomeres (the guarding caps located at the end of chromosomes) and an increase in senescent cells.

A scientific experiment involving 35 individuals over the age of 64 was conducted to understand whether a Hyperbaric Oxygen Therapy technique could prevent the decline of these two elements of the aging process.

The HBOT is a controversial treatment – it can lead to a number of adverse effects, as it involves oxygen at a high atmospheric pressure. However, striking and poorly-evidenced studies claim that it can treat diseases ranging from aseptic bone necrosis, global brain ischemia to autism.

The study participants were placed in a pressurized chamber and were given 90-minute pure oxygen sessions five days a week for three months.

At the end of the experiment, the specialists proclaimed that the participants’ telomeres had increased in length by an average of 20%, while their senescent cells had been reduced by up to 37%.

The researchers reported that it is the equivalent of how their bodies were at a cellular level 25 years earlier.

A Professor at the Tel Aviv University, and co-author of the research, Shai Efrati, stated, “The reduction of telomeres is considered as the ‘Holy Grail’ of the biology of aging. Numerous pharmacological and environmental interventions have been widely examined in the hopes of enabling telomere elongation.”

He added, “The notable improvement of telomere length gives the research community a new foundation of understanding that aging can, indeed, be targeted and reversed at the fundamental cellular-biological level.”

The development is the latest in a series of radical anti-aging treatments that seek to increase life expectancy and make people look and feel younger.
