The scholarly study is published in the journal Nature.. Anti-cancer gene p53 doubles up while anti-ageing agent The latest research suggests that one of the genes that protects us from cancer also may help delay the ageing process. A fresh study has found that a particular gene, p53 which has been associated with premature ageing, along with among its cellular regulators, called Arf, may raise the body’s antioxidant activity to keep cells younger much longer and thereby slow down growing older. The regulatory chemical Arf, lets p53 know that a particular cell is in big trouble and marked for elimination. Manuel Serrano, a researcher at the Spanish National Cancers Research Centre in Madrid, says your body ages as a result of the accumulation of faulty cells and p53 delays ageing for exactly the same cause that it prevents cancer.
