During acute glucose restriction, activated AMPK was stabilized from degradation and interacted with Atg14p. More gradual glucose starvation, amino acid deprivation or rapamycin did not trigger µ-lipophagy and failed to provide the needed substitute energy source for long-term survival. AMP-activated protein kinase (AMPK) activation triggered this pathway, which required Atg14p. We demonstrate that to permit long-term survival in response to sudden glucose depletion, yeast cells activate lipid-droplet (LD) consumption through micro-lipophagy (µ-lipophagy), in which fat is metabolized as an alternative energy source. Schwartz’s interests not only include sports medicine and arthroscopic surgery, but general orthopaedics as well.Dietary restriction increases the longevity of many organisms, but the cell signaling and organellar mechanisms underlying this capability are unclear.
