RNA molecule rejuvenates ageing mice
Injecting old mice with an RNA molecule called miR-302b seems to reverse some signs of ageing — helping them to live longer, regrow hair and maintain their physical and mental abilities. The treatment works by targeting one of the hallmarks of the ageing process: a stage called cellular senescence, in which cells lose their ability to replicate. Researchers hope the findings could one day lead to the development of anti-ageing drugs, but more work is needed to determine whether they translate to people.
