Schematic overview of the proposed role of cyclooxygenase-mediated lipid droplet degradation in response to nutrition deprivation in zebrafish hepatocytes. Serum starvation triggers the release of arachidonic acid and augments the production of PGF2α, which is a key molecule promoting lipid mobilization via autophagy/lipophagy and lipolysis as well as mitochondrial energy production.
