Abstract
Ferritinophagy is a regulatory pathway of iron homeostasis. It is a process in which nuclear receptor coactivator 4 (NCOA4) carries ferritin to autophagolysosomes for degradation. After ferritin is degraded by autophagy, iron ions are released, which promotes the labile iron pool (LIP) to drive the Fenton reaction to cause lipid peroxidation. Furthermore, ferroptosis promoted by the accumulation of lipid reactive oxygen species (ROS) induced by ferritinophagy can cause a variety of systemic diseases. In clinical studies, targeting the genes regulating ferritinophagy can prevent and treat such diseases. This article describes the key regulatory factors of ferritinophagy and the mechanism of ferritinophagy involved in ferroptosis. It also reviews the damage of ferritinophagy to the body, providing a theoretical basis for further finding clinical treatment methods.
期刊介绍：
Pathology, Research and Practice provides accessible coverage of the most recent developments across the entire field of pathology: Reviews focus on recent progress in pathology, while Comments look at interesting current problems and at hypotheses for future developments in pathology. Original Papers present novel findings on all aspects of general, anatomic and molecular pathology. Rapid Communications inform readers on preliminary findings that may be relevant for further studies and need to be communicated quickly. Teaching Cases look at new aspects or special diagnostic problems of diseases and at case reports relevant for the pathologist''s practice.
