NFS1, together with FXN, protects cells from ferroptosis and DNA damage in diffuse large B-cell lymphoma

Shi X, Zhao Y, Gao HY, Yang W, Liao J, Wang HH, Wang XT, Yan W. NFS1, together with FXN, protects cells from ferroptosis and DNA damage in diffuse large B-cell lymphoma. Redox Biol. 2025 Nov;87:103878. doi: 10.1016/j.redox.2025.103878. Epub 2025 Sep 23. PMID: 41005206; PMCID: PMC12505007.

We demonstrated that ISC-related proteins NFS1 and FXN protect DLBCL cells from ferroptosis and DNA damage, thus exhibiting an essential role in DLBCL progression.

Partial Bypass of Frataxin Deficiency by ISCU M141I Restores Cytosolic and Nuclear Fe-S Cluster Assembly

Mosbach V, Maio N, Diedhiou N, Hennick A, Dall'Agnol L, Reutenauer L, Marczak L, Birling MC, Eisenmann A, Martelli A, Hélène PH. Partial Bypass of Frataxin Deficiency by ISCU M141I Restores Cytosolic and Nuclear Fe-S Cluster Assembly. bioRxiv [Preprint]. 2025 Sep 6:2025.09.03.673074. doi: 10.1101/2025.09.03.673074. PMID: 41019637; PMCID: PMC12466782. 

 Altogether, our results reveal a previously unrecognized compartment-specific rescue of Fe-S cluster dependent processes by the ISCU M141I variant in mammalian cells, raising for the first time the possibility of compartmental regulation of Fe-S cluster biogenesis.

Scoliosis Surgery in a Patient With Advanced Friedreich's Ataxia-It Is Not Too Late. Ann Clin Transl Neurol. 2025 Oct 3. doi: 10.1002/acn3.70219. Epub ahead of print. PMID: 41044041. 

 This case highlights the potential for substantial clinical and functional benefits from scoliosis surgery in patients with advanced Friedreich's ataxia.

From Mutations to Microbes: Investigating the Impact of the Gut Microbiome on Repeat Expansion Disorders

Das S, Patel M, Khandelwal S, Rawat R, Shukla S, Kumari AP, Singh K, Kumar A. From Mutations to Microbes: Investigating the Impact of the Gut Microbiome on Repeat Expansion Disorders. J Neurochem. 2025 Nov;169(11):e70278. doi: 10.1111/jnc.70278. PMID: 41194479. 

 Alterations in microbial diversity and composition have been observed across multiple REDs; however, a comprehensive understanding of the complete scenario remains a significant challenge. To elucidate these dynamic interactions, future research should utilize multifaceted approaches. This review focuses on the key modifications in the gut microbiome that contribute to the pathogenesis of REDs and discusses potential gut microbiome-targeted therapeutic strategies that could be effectively employed to treat these disorders.

Mitochondria-Mediated Mechanisms of Ferroptosis in Neurological Diseases

Zhong R, Yang H, Li X, Wang F, Zhai L, Gao J. Mitochondria-Mediated Mechanisms of Ferroptosis in Neurological Diseases. Neurochem Res. 2025 Nov 10;50(6):354. doi: 10.1007/s11064-025-04605-6. PMID: 41212342. 

This review first comprehensively explores the multifaceted mechanisms by which mitochondria mediate ferroptosis in neurological diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), Friedreich's ataxia (FRDA), amyotrophic lateral sclerosis (ALS), epilepsy, stroke, and brain injury, with a focus on mitochondrial lipid peroxidation and iron metabolism dysregulation. Building on these mechanistic insights, we further discuss emerging evidence suggesting that targeting mitochondrial pathways may represent a promising therapeutic strategy for mitigating ferroptosis-associated neuronal damage. By synthesizing these findings, our review establishes a conceptual foundation for developing innovative neuroprotective interventions through precise modulation of mitochondrial function within ferroptotic pathways.
