"She had been dead for more than three hours. Biogerontologist Aubrey de Grey believes that reversing aging may actually be more feasible than slowing aging, in the same sense that is sometimes more economical to periodically repair damage than to go to extraordinary expense to slow the rate of damage. Unlike yeast Sir2 (which exclusively deacetlyates histones) sirt1 has a wide range of substrates genes AMP; development; Haigis, MC; 20(21 (2006) including p53 and foxo3 protein which sirt1 silences by direct deacylation reputed to prevent "premature senescence" and "premature apoptosis".
