The clinical trials were small studies but showed promising results in humans, he said. There have been some clinical trials around the world, and we're hoping in the next few years to know if this will actually work in people as well,' he said. 'We've gone from mice into early human studies actually. Professor Sinclair said the breakthroughs could be used to develop drugs to restore youthfulness in human cells. 'We fed them a molecule that's called NMN and this reversed ageing completely within just a week of treatment in the muscle, and now we're looking to reverse all aspects of ageing if possible.' 'We've discovered genes that control how the body fights against ageing and these genes, if you turn them on just the right way, they can have very powerful effects, even reversing ageing - at least in mice so far,' he said. Professor of genetics at Harvard and UNSW, David Sinclair, led the research team. The scientists said they switched youthful genes on and older genes off, using naturally occurring proteins and molecules. The research has focused on mice, but early clinical trials have also been conducted on humans. Scientists from Harvard and the University of New South Wales say they have discovered how to reverse the ageing process.
