Autophagy declines with age, yet it is unclear if restoration of autophagy extends lifespan. Here, the authors demonstrate in murine models that the inhibition of Atg5 induces ageing phenotypes and reduces lifespan, whilst autophagy restoration partially reverses these phenotypes with accelerated tumorigenesis.
