The multifaceted regulation of mitochondria in ferroptosis

Abstract

Ferroptosis is characterized as a novel form of regulated cell death, which is initiated by the lethal accumulation of lipid peroxidation catalyzed by cellular labile free iron. This iron driven cell death sharply differs from other well characterized forms of regulated cell death at morpholog-ical, genetic and biochemical levels. Increasing research has elaborated a high relevance between dysregulated ferroptosis and the pathogenesis of degenerative diseases and organs injury in human patients. Additionally, targeted induction of ferroptosis is considered as a potentially therapeutic design for the clinical intervention of other therapy-resistant cancers. It is well understood that mi-tochondria, the cellular powerhouse, determine several types of regulated cell death. Recently, com-promised mitochondrial morphology and functionalities have been primarily formulated in ferrop-tosis. Several mitochondria associated proteins and metabolic processes have been elaborated to fine-tune ferroptotic program. Herein, we critically review the recent advances in this booming field, with focus on summarizing the multifaceted mitochondrial regulation of ferroptosis and providing a perspective on the potential biochemical basis. Finally, we are attempting to shed light on an in-tegrative view on the possibility of mitochondria-and ferroptosis-targeting therapeutics as novel treatment designs for the intervention of ferroptosis related diseases.
