Scientists are a step closer to creating an anti-ageing drug, after they discovered a key anti-ageing enzyme that stops our cells from decaying.
It has long been known that reducing calorie intake can dramatically slow the process of ageing and improve health in later life.
Now researchers from the University of Wisconsin-Madison have identified a key enzyme called Sirt3, which causes this dramatic effect in cell molecules.
Lead scientist Professor Tomas Prolla said: ‘We’re getting closer and closer to a good understanding of how caloric restriction works.
‘This study is the first direct proof for a mechanism underlying the anti-aging effects we observe under caloric restriction.’
The finding not only helps explain the cascade of events that contributes to ageing, but also provides a basis for devising drugs that could extend the average life span.
