Short-term starvation activates AMPK and restores mitochondrial inorganic polyphosphate, but fails to reverse associated neuronal senescence. [PDF]

open access: yesAging Cell
In this manuscript, Tagliafico et al. address the relationship between the levels of inorganic polyphosphate (polyP) and the onset of neuronal senescence. Moreover, they show that short‐term starvation restores depleted levels of polyP and activates AMPK; however, this is not sufficient to reverse the increased senescence associated to decreased polyP.
