FOXO1‐NCOA4 Axis Contributes to Cisplatin‐Induced Cochlea Spiral Ganglion Neuron Ferroptosis via Ferritinophagy

Advanced Science, Journal Year: 2024, Volume and Issue: 11(40)

Published: Aug. 29, 2024

Abstract Mammalian cochlea spiral ganglion neurons (SGNs) are crucial for sound transmission, they can be damaged by chemotherapy drug cisplatin and lead to irreversible sensorineural hearing loss (SNHL), while such damage also render cochlear implants ineffective. However, the mechanisms underlying cisplatin‐induced SGNs subsequent SNHL still under debate there is no currently effective clinical treatment. Here, this study demonstrates that ferroptosis triggered in following exposure cisplatin. Inhibiting protects against loss, inducing intensifies these effects. Furthermore, prompts nuclear receptor coactivator 4 (NCOA4)‐mediated ferritinophagy SGNs, knocking down NCOA4 mitigates loss. Notably, upstream regulator of identified transcription factor forkhead box O1 (FOXO1) shown directly suppress expression SGNs. The FOXO1 amplifies NCOA4‐mediated ferritinophagy, increases lipid peroxidation, disrupting interaction between knock out mice prevents SGN Collectively, highlights critical role FOXO1‐NCOA4 axis regulating damage, offering promising therapeutic targets mitigation.

Ferrostatin-1 improves acute sepsis-induced cardiomyopathy via inhibiting neutrophil infiltration through impaired chemokine axis

Frontiers in Cell and Developmental Biology, Journal Year: 2024, Volume and Issue: 12

Published: Dec. 12, 2024

Introduction Sepsis-induced cardiomyopathy is a common complication of sepsis and associated with higher mortality. To date, effective diagnostic management strategies are still lacking. Recent studies suggest that ferroptosis plays critical role in sepsis-induced inhibitor Ferrostatin-1 (Fer-1) improved cardiac dysfunction survival lipopolysaccharide (LPS) induced endotoxemia. However, the effects Fer-1 early stages cecal ligation puncture (CLP) remains unclear. Our study aims to elucidate acute phase peritonitis injury. Methods Results CLP was used induce mice. Pretreatment ferrostatin-1 vivo models. Survival monitored for 48h. Cardiac function histology were analyzed 6h after surgery. We found ejection fraction (EF) remained normal at CLP, but contractility detected by muscle strain analysis significantly reduced, along increased immune cell infiltration. Pretreating mice 5 mg/kg reduced At key regulator Gpx4, iron malonaldehyde (MDA) did not change, marker gene expression increased. treatment showed beneficial function, less myocardial inflammatory cytokine inhibited cells, especially neutrophil infiltration heart. Consistently, chemokines (Ccrl2, Cxcl2, Cxcl3 Cxcl5) as well extracellular matrix (ECM) degradation enzymes (Adamts1, Adamts4, Adamts9 Mmp8) decreased pre-treated Conclusion Discussion findings inhibits disrupting chemokine axis, highlighting its potential therapeutic option manage overactivation cardiomyopathy.

Transforming Growth Factor‐β‐Activated Protein 1 (TAK1) Regulates Necroptosis in Age‐Related Hearing Loss

Aging Cell, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 28, 2025

ABSTRACT Inflammation plays an important role in age‐related hearing loss (ARHL). Transforming growth factor‐β‐activated protein 1 (TAK1), a key factor upstream of inflammatory pathways, mediates various cell death potentially influencing the survival and cochlear hair cells. The DBA/2 J mouse model HEI‐OC1 line were used to investigate mechanism TAK1‐mediated inflammation ARHL. Hematoxylin eosin staining revealed significant histological damage cochlea 16‐week‐old mice, along with increase auditory‐evoked brainstem response thresholds. Concurrently, TAK1 mRNA levels decreased sharply, necroptosis significantly increased indicating correlation between expression, necroptosis, loss. We subsequently constructed knockdown overexpression cells for further investigation. activated necroptotic pathway, characterized by up‐regulation RIPK3 MLKL , down‐regulation NF‐κB Caspase 8 . However, successfully prevented cells, leading decreases treated inhibitors found that they could reverse caused This preliminary study shows pathways play pathogenesis

Cisplatin can cause irreversible hearing loss. However, effective approaches to its prevention are not established. In this study, the effect of traditional Chinese medicine monomer pinoresinol diglucoside (PDG) is evaluated on cisplatin-induced ototoxicity and underlying mechanism action. PDG significantly increases cell viability inhibits reactive oxygen species production ferroptosis in cisplatin-treated House Ear Institute-Organ Corti 1 cells basilar membranes. partially restores loss caused by cisplatin. Transcriptome sequencing identifies Suppressor Cytokine Signaling (SOCS1), which elevated cisplatin-only group but reduced after application.
