Spindler’s team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old-equivalent to about 70 human years.
The researchers checked the activity of 11,000 genes from the mouse livers,and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free production-probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes.
The researchers found that ______ genes changed with age in the mice that had dieted all their lives.
