Scientists Reverse the Aging Clock: Restore Age-Related Vision Loss Through Epigenetic Reprogramming


  • Proof-of-concept study represents first successful attempt to reverse the aging clock in animals through epigenetic reprogramming.
  • Scientists turned on embryonic genes to reprogram cells of mouse retinas.
  • Approach reversed glaucoma-induced eye damage in animals.
  • Approach also restored age-related vision loss in elderly mice.
  • Work spells promise for using same approach in other tissues, organs beyond the eyes.
  • Success sets stage for treatment of various age-related diseases in humans

“Our study demonstrates that it’s possible to safely reverse the age of complex tissues such as the retina and restore its youthful biological function,” said senior author David Sinclair, professor of genetics in the Blavatnik Institute at Harvard Medical School, co-director of the Paul F. Glenn Center for Biology of Aging Research at HMS and an expert on aging.

The article specifically states they've overcome the tumor problem. I would love to toss out my reading/ working glasses!!! But this seems to be a big step toward restoring youth in all sorts of tissues.
