Lipid storage and lipophagy regulates ferroptosis
Abstract
The synthesis, storage, and degradation of lipids are highly regulated processes. Impaired lipid metabolism is implicated in inflammation and cell death. Although ferroptosis is a recently described form of regulated cell death driven by lipid peroxidation, the impact of lipid droplets on ferroptosis remains unidentified. Here, we demonstrate that lipophagy, the autophagic degradation of intracellular lipid droplets, promotes RSL3-induced ferroptotic cell death in hepatocytes. Lipid droplet accumulation is increased at the early stage but decreased at the late stage of ferroptosis in mouse or human hepatocytes. Importantly, either genetically enhancing TPD52-dependent lipid storage or blocking ATG5-and RAB7A-dependent lipid degradation prevents RSL3-induced lipid peroxidation and subsequent ferroptosis in vitro and in vivo. These studies support an antioxidant role for lipid droplets in cell death and suggest novel strategies for the inhibition of ferroptosis by targeting the lipophagy pathway.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
