Abstract

Ferroptosis is an iron-dependent form of regulated cell death, driven by the accumulation of lipid peroxidation. Autophagy is a lysosome-dependent degradation process that can be used to remove and recover intracellular components, such as dysfunctional proteins and damaged organelles. By regulating iron storage and oxidative stress, excessive autophagy is involved in the induction and execution of ferroptosis. In particular, several types of selective autophagy (e.g., ferritinophagy, lipophagy, clockophagy, and chaperone-mediated autophagy) increase the susceptibility to ferroptotic cell death by degrading anti-ferroptotic regulators (e.g., ferritin, GPX4, ARNTL, and lipid droplets). These two integrated biological processes play a pathological role in the occurrence and development of human diseases, such as cancer, neurodegenerative disorders, ischemia and reperfusion injury. Therefore, it is important to develop reliable methods to evaluate the kinetics of autophagosome formation, iron accumulation, and lipid peroxidation. Here, we introduce some protocols (such as western blotting, lipid peroxidation assay kits and probes, and iron probes) to monitor the process of autophagy-dependent ferroptosis.
