"Super p53" mice exhibit enhanced DNA damage response, are tumor resistant and age normally

Researchers genetically changed mice so they had an extra working copy of the p53 gene, which helps detect and stop damaged cells. These mice showed a stronger DNA damage response, meaning their cells reacted more effectively to harmful changes in DNA. They developed fewer tumors than ordinary mice. They also had a normal lifespan and did not show obvious signs of faster aging. This was an animal study, not a study in people.

What this means for you: This suggests that stronger natural cancer protection might not always shorten lifespan, but it does not show that boosting p53 will help humans. You can ignore products claiming this study proves an anti-aging treatment works.
