Ferroptosis is a regulated iron-dependent cell death mechanism characterized by the accumulation of peroxidized phospholipids, particularly phosphatidylethanolamine. It is involved in the pathogenesis of various human diseases, with mitochondria potentially mediating the signaling pathways of ferroptosis.
Ferroptosis is a regulated iron-dependent cell death mechanism accompanied by the accumulation of peroxidized phospholipids, particularly phosphatidylethanolamine, in the cell. It occurs due to the disbalance between production and elimination of oxidized phospholipids in response to ferroptotic stimuli. A growing body of recent studies indicates that ferroptosis is involved in the pathogenesis of various human diseases leading to organ/tissue abnormalities. Because of their central role in ATP synthesis, ROS production, iron homeostasis, and redox status, mitochondria have been proposed to mediate ferroptotic signaling pathways. However, precise mechanisms underlying the potential role of mitochondria in ferroptosis remain unrevealed. This review summarizes and discusses previous studies on the contribution of mitochondria to ferroptotic cell death and highlights future directions elucidating the mitochondria as a promising target to prevent cell death through blocking ferroptosis.
