Tel Aviv, May 30 -- Israeli scientists have found evidence that some aspects of ageing may be reversible, after a study that restored aged liver cells in mice to a more youthful state, Bar-Ilan University announced.

The study showed that increasing the activity of a protein called SIRT6 can reverse age-related deterioration in how DNA is organised and used inside cells. Researchers say this is the first time SIRT6 has been shown to restore youthful molecular patterns in already aged animals, rather than merely slowing age-related changes when activated earlier in life.
