Tuning p53 Performance

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

More interesting research into the p53 gene is ongoing; Medical News Today reports that scientists can now control its performance level. We know that the mechanisms associated with p53 suppress cancer by destroying cells with damaged DNA, but it may also be the case that upgrading its level of performance could cause accelerated aging - rather than extending life by giving us greater resistance to the detrimental effects of accumulated damage to nuclear DNA. We are entering an exciting era in biotechnology; the black box of the cell is opening up to inspection, manipulation and experimentation. Understanding a machine implies the ability to control, repair and improve that machine - and certainly the ability to extend its operational life span.
