WebFeb 28, 2024 · Mechanistic dissection in cultured cells showed that lipid peroxidation at the PM was required, and sufficient, to induce the cytosolic redistribution of CAVIN1 under oxidative stress. Intracellular CAVIN1 released from caveolae was shown to interact with NRF2, promoting NRF2 degradation and triggering ferroptosis.
WebOct 13, 2024 · Reactive oxygen species- (ROS-) induced lipid peroxidation plays a critical role in cell death including apoptosis, autophagy, and ferroptosis. This fundamental and conserved mechanism is based on an excess of ROS which attacks biomembranes, propagates lipid peroxidation chain reactions, and subsequently induces different types … WebJul 26, 2024 · ROS-induced oxidative stress exacerbates the production of lipid peroxidation (LPO).

WebApr 7, 2024 · Ferroptosis is an iron-dependent nonapoptotic cell death driven by the accumulation of lipid reactive oxygen species (ROS). Glutathione (GSH)/glutathione peroxidase 4 (GPX4) plays a pivotal role in protecting cells from ferroptosis by hydrolyzing lipid hydroperoxides. Mounting evidence supports the crucial role of ferroptosis in tumor …
