'Super p53' mice age normally

Researchers created genetically altered mice with an extra working copy of the p53 gene, which helps prevent damaged cells from becoming cancerous. They compared these mice with ordinary mice as they aged. The altered mice resisted some cancers better, but they showed normal aging and lived about as long as ordinary mice. This was a mouse study, so it does not directly show what would happen in humans.

What this means for you: This does not support buying or taking anything to increase p53. It is an interesting early finding in mice, but no human benefit or safety was shown.
