The researchers insist that the boost in life expectancy was not a result of fewer mice dying of cancer. They claim that a look at cancer-free mice showed them that transgenic mice lived 25 per cent longer, on average, than normal ones.

Although the oldest mice in both groups died at about the same age, more of the transgenic mice lived into their golden years than their normal counterparts.

Upon closely observing the youthful mice, the researchers found higher levels of genes that combat oxidative damage than in regular rodents. The mice with extra p53 also held up better against a lethal dose of paraquat, a drug that causes oxidative damage.
