Researchers Have Found The Way To Reverse Aging In Mice And Humans

By undoing the changes in gene activity which are brought about by everyday life, scientists have started to slow and even reverse, aging.

The scientists tweaked genes which turn adult cells back into embryonic-like ones in mice and have resonant success extending their lives.

The changes involved the reversal of mouse and human cells in vitro, which extended the life of one mouse with an accelerated-aging condition and also successfully promoted recovery from an injury in the middle-aged mouse.

According to Juan Carlos Izpisua Belmonte, the research’s senior author and also an expert in gene expression at Salk: “aging is something plastic that we can manipulate.”

The research is continuing at the Salk Institute for Biological Studies.
In their research, they rejuvenated cells by briefly turning on 4 genes that can turn adult cells back into an embryonic-like state.

According to David Sinclair, a Harvard University geneticist and anti-aging researcher who wasn’t involved in the study but is doing similar work: “I do think that epigenetic reprogramming is the ultimate way to reverse aging.”

Matt Kaeberlein, a molecular biologist at the University of Washington who studies aging but wasn’t part of the work, suggests it might be possible not just to slow aging but also to reverse it. “That’s really exciting—that means that even in elderly people it may be possible to restore youthful function,” he claims.

The molecular biology community is still buzzing, and our life expectancies keep extending.

Matt Kaeberlein, a molecular biologist at the University of Washington who studies aging but was not part of the work, suggests it may be possible not just to slow aging but to actually reverse it. “That’s really exciting—that means that even in elderly people it may be possible to restore youthful function,” he says.

The molecular biology community continues to buzz and our life expectancies keep extending.  This is an exciting tim to be alive.
