Chinese scientists working on gene therapy to delay aging [Video]


  • A group of biologists the Chinese Academy of Sciences in Beijing is working on a gene therapy that could possibly delay human ageing.
  • The treatment is being tested among mice which showed “overall improved appearance and grip strength,” as well as an “extended lifespan for about 25%.”
  • There’s still a long road ahead of the method, though — which will need generous funding and rigorous research — before becoming ready for human trials.

A longer life by reversing effects of ageing can be scientifically made possible.

Scientists at the Chinese Academy of Sciences in Beijing said they have developed a world-first new gene therapy that will slow the human aging process.

The therapy is being run on mice, screening around 10,000 genes in search of particularly strong drivers of cellular ageing.

In that pool, the group of biologists have identified 100 genes, with kat7 classified as the one really standing out.

The kat7 gene, one of tens of thousands of genes found in the cells of mammals, was inactivated in the livers of mice.

Professor Qu Jing explained, “These mice show after six to eight months, they show overall improved appearance and grip strength and most importantly they have extended lifespan for about 25%.”

The function of the kat7 gene was also tested in human stem cells, human liver cells and more — with no side effects of cellular toxicity so far.

Nevertheless, the group had recognized that the scientific innovation still has a long way to go before it gets ready for human trials. It will also need a lot of funding and further studies before potential launch.

The scientists hope that, in the future, there could be a way to delay ageing even by a very minor percentage.
