Integration of a second copy of SIR2 into the wild-type strain leads to an extension of replicative lifespan by around 35% in W303R strain[10521401]. 0.05% glucose restriction further extends replicative lifespan of SIR2 overexpression mutant [15328540]. Overexpression extends replicative lifespan in several strains, but not in PSY316
Mean: +35
