p53 controls ageing
The p53 protein works to suppress cancer cells by the induction of senescence, apoptosis and cell cycle arrest, but its role in the longevity of organisms remains unknown. In 3 January Nature, Stuart Tyner and colleagues from Baylor College of Medicine, Houston, USA, show that p53 has a role in controlling ageing in mice.Tyner et al. generated mice with a mutation that confers phenotypes consistent with activated p53. They found that mutated mice are highly resistant to tumors but display early
