Abstract:
Ferritinophagy is a selective form of autophagy in which ferritin, the primary intracellular iron storage protein complex, is targeted by NCOA4 (Nuclear receptor coactivator 4) to the lysosome for degradation. NCOA4-mediated ferritinophagy plays a crucial role in cellular iron metabolism, influencing iron homeostasis, heme synthesis, mitochondrial respiratory function, and ferroptosis, an iron-dependent form of cell death. Targeting ferritinophagy has emerged as a potential anticancer therapeutic strategy. In this context, we provide a flowchart of the procedures and accompanying protocols for monitoring ferritinophagic flux.
