Anti-ageing compound set for human trials after turning clock back for mice

New South Wales professor in US rolled back the key indicators of ageing to make two-year-old mice appear six months old

Australian and US researchers hope an anti-ageing compound could be trialled on humans as early as next year, following a key breakthrough that saw the ageing process reversed in mice.
The study, involving Harvard University and the University of NSW, discovered a way of restoring the efficiency of cells, completely reversing the ageing process in muscles.
Two-year-old mice were given a compound over a week, moving back the key indicators of ageing to that of a six-month-old mouse. Researchers said this was the equivalent of making a 60-year-old person feel like a 20-year-old.
It’s hoped the research, published in Cell, will be expanded to humans as early as next year, with scientists set to look at how the theory of age reversal can be used to treat diseases such as cancer, dementia and diabetes.
