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.

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.

Cracking the code: a head-to-head comparison of expert clinicians and artificial intelligence in diagnosing rare diseases

Sendtner, G.W., Muecke, M., Grigull, L. et al. Cracking the code: a head-to-head comparison of expert clinicians and artificial intelligence in diagnosing rare diseases. Orphanet J Rare Dis 20, 564 (2025). doi:10.1186/s13023-025-04112-5

In this study, we showed that the differential diagnostic tool “Isabel Healthcare” can assist in identifying patient diagnoses. However, discrepancies between the tool’s output and the interdisciplinary case conferences were observed, indicating that while “Isabel Healthcare” can aid clinicians when filtered input is applied, it may not yet be fully effective on its own. Our findings highlight the potential of tools like “Isabel Healthcare” in the diagnostic process but emphasize the essential role of clinicians in filtering and contextualizing medical information.

Lischewski, Kerstin Konrad, Miguel Pishnamaz, Maximillian Praster, Thomas Clavel, Vera Jankowski, Joachim Jankowski, Oliver Pabst, Katharina Marx-Schütt, Nikolaus Marx, Julia Möllmann, Malte Jacobsen, Juergen Dukart, Simon Eickhoff, Deep learning-based 3D reconstruction of dentate nuclei in Friedreich’s ataxia from T2*weighted MR images, Machine Learning with Applications, 2025, 100790, ISSN 2666-8270, doi:10.1016/j.mlwa.2025.100790. 

 We present a transfer learning–based machine learning pipeline for automated DN segmentation that directly uses standard T2*-weighted Magnetic Resonance Imaging (MRI), which highlights the DN without additional processing, and is designed to perform robustly with limited annotated data.
