we showed in 2005 in a Science paper that when you take a calorie-restricted rat and look at its organs...we looked at the liver and muscle, the levels of one of the sirtuin genes, number one, we have seven of these genes. So we looked at number one because we only had an antibody in those days to number one. It went up dramatically. I think it was about five to tenfold in levels in the calorie-restricted livers.
