Abstract

Macroautophagy/autophagy is a complex degradation process with a dual role in cell death that is influenced by the cell types that are involved and the stressors they are exposed to. Ferroptosis is an iron-dependent oxidative form of cell death characterized by unrestricted lipid peroxidation in the context of heterogeneous and plastic mechanisms. Recent studies have shed light on the involvement of specific types of autophagy (e.g. ferritinophagy, lipophagy, and clockophagy) in initiating or executing ferroptotic cell death through the selective degradation of anti-injury proteins or organelles. Conversely, other forms of selective autophagy (e.g. reticulophagy and lysophagy) enhance the cellular defense against ferroptotic damage. Dysregulated autophagy-dependent ferroptosis has implications for a diverse range of pathological conditions. This review aims to present an updated definition of autophagy-dependent ferroptosis, discuss influential substrates and receptors, outline experimental methods, and propose guidelines for interpreting the results.Abbreviation: 3-MA:3-methyladenine; 4HNE: 4-hydroxynonenal; ACD: accidentalcell death; ADF: autophagy-dependentferroptosis; ARE: antioxidant response element; BH2:dihydrobiopterin; BH4: tetrahydrobiopterin; BMDMs: bonemarrow-derived macrophages; CMA: chaperone-mediated autophagy; CQ:chloroquine; DAMPs: danger/damage-associated molecular patterns; EMT,epithelial-mesenchymal transition; EPR: electronparamagnetic resonance; ER, endoplasmic reticulum; FRET: Försterresonance energy transfer; GFP: green fluorescent protein;GSH: glutathione;IF: immunofluorescence; IHC: immunohistochemistry; IOP, intraocularpressure; IRI: ischemia-reperfusion injury; LAA: linoleamide alkyne;MDA: malondialdehyde; PGSK: Phen Green™ SK;RCD: regulatedcell death; PUFAs: polyunsaturated fatty acids; RFP: red fluorescentprotein;ROS: reactive oxygen species; TBA: thiobarbituricacid; TBARS: thiobarbituric acid reactive substances; TEM:transmission electron microscopy.

Figures

**Figure 1.**
Overview of ferroptosis. The SLC7A11-GSH-GPX4 pathway and GPX4-independent pathways (such as AIFM2, GCH, DHODH, and MGST1) inhibit lipid peroxidation, whereas ACSL4, ALOX, and POR promote peroxidation of PUFA-containing phospholipids (PUFA-PL). Cystine is transported into cells by SLC7A11 and rapidly reduced to cysteine, which is utilized for GSH synthesis. GPX4 inhibits lipid peroxidation, the primary driver of ferroptosis, by converting GSH to GSSG. The transcription factor NFE2L2 serves as a key antioxidant system by upregulating genes involved in both GPX4-dependent and GPX4-independent pathways. Lipid peroxidation generates 4HNE, which can induce membrane damage and release DAMPs. Conversely, the endosomal sorting complex required for transport (ESCRT-III) machinery acts as a protective mechanism that delays membrane damage. TFRC increases intracellular iron levels, thereby promoting lipid peroxidation and ferroptosis.

**Figure 2.**
Classification of ferroptosis based on autophagic response. Autophagy-dependent ferroptosis: this process relies on the autophagic machinery to induce ferroptosis. Autophagy-independent ferroptosis: In this case, autophagy occurs alongside ferroptosis but does not directly induce ferroptosis or may even have a protective role in the context of ferroptosis.

**Figure 3.**
Ferritinophagy in ferroptosis. Ferritin is a cytosolic protein involved in iron storage, and NCOA4 serves as a receptor for the autophagic degradation of ferritin, a process referred to as ferritinophagy. Conditions and factors such as hypoxia, TRIM7, and HERC2 decrease NCOA4 expression, thereby inhibiting ferritinophagy-dependent ferroptosis. Conversely, PTBP1 and ATM promote NCOA4-mediated ferritinophagy. Additionally, ALDH1A3 can bind to MAP1LC3 to enhance ferritinophagy-dependent ferroptosis.

**Figure 4.**
Lipophagy in ferroptosis. Lipophagy refers to the autophagic clearance of lipid droplets, which function as storage organelles for neutral lipids. RAB7A, associated with lipid droplets, drives lipophagy and promotes subsequent ferroptosis. The formation of lipid droplets, mediated by TPD52 and PLTP, antagonizes lipophagy-dependent ferroptosis. In contrast, PGRMC1 triggers lipophagy-dependent ferroptosis. PUFA, polyunsaturated fatty acid.

**Figure 5.**
Mitophagy in ferroptosis. Mitophagy is a selective process that involves the autophagic clearance of damaged or dysfunctional mitochondria. The PINK1-PRKN pathway is a well-studied regulatory pathway for mitophagy. In this pathway, PINK1 recruits PRKN, which facilitates the degradation of mitochondria through mitophagy receptors such as FUNDC1. Mitochondrial fission induced by DNM1L/Drp1 can promote mitophagy-dependent ferroptosis. Additionally, the mitochondrial protein FTMT inhibits ROS production and ferroptosis.

**Figure 6.**
Clockophagy in ferroptosis. BMAL1/ARNTL, a transcription factor involved in the circadian clock, undergoes selective degradation through autophagy, a process known as clockophagy. The autophagy receptor SQSTM1/p62 plays a role in recognizing and degrading BMAL1 during clockophagy. Degradation of BMAL1 results in the upregulation of *EGLN2*, a target gene of BMAL1. EGLN2, in turn, inhibits the function of HIF1A, which acts as a suppressor of ferroptosis by inducing the expression of FABP3 and FABP7. These proteins regulate fatty acid uptake and lipid storage, thereby limiting the availability of polyunsaturated fatty acid (PUFA) and influencing the susceptibility to ferroptosis.

**Figure 7.**
CMA- or TAX1BP1-mediated GPX4 degradation in ferroptosis. CMA serves as a pathway for GPX4 protein degradation during ferroptosis. LAMP2 plays a key role in transporting GPX4 across the lysosomal membrane, and HSPA8/HSC70 interacts with GPX4 and LAMP2, facilitating CMA. CMA-mediated degradation of GPX4 can be inhibited by CKB-mediated GPX4 phosphorylation. LGMN assists in CMA-mediated GPX4 degradation. Furthermore, macroautophagy/autophagy also contributes to GPX4 degradation during ferroptosis. SMPD1/ASM promotes the autophagic degradation of GPX4, whereas MTOR inhibits GPX4 protein degradation and subsequent ferroptosis. Copper directly binds to GPX4, leading to its autophagic degradation, and, in this process, TAX1BP1 acts as an autophagic receptor.
