Ferroptosis Transcriptional Regulation and Prognostic Impact in Medulloblastoma Subtypes Revealed by RNA-Seq by Christophe Desterke, Yuanji Fu, Jenny Bonifacio-Mundaca, Claudia Monge, Pascal Pineau, Jorge Mata-Garrido, Raquel Francés

“…WGCNA identified nine gene modules in the MB tumor transcriptome; five correlated with molecular subtypes, implicating pathways related to oxidative stress, hypoxia, and trans-synaptic signaling. One module, associated with disease recurrence, included epigenetic regulators and nucleosome organizers. …”

Characteristic alterations of gut microbiota and serum metabolites in patients with chronic tinnitus: a multi-omics analysis by Jiang Wang, Jia-Hui Xiang, Xu-Yuan Peng, Min Liu, Le-Jia Sun, Min Zhang, Li-Yuan Zhang, Zhi-Bin Chen, Zheng-Quan Tang, Lei Cheng

“…In serum metabolomic analysis, serum metabolic disturbances in tinnitus patients and these differential metabolites were enriched in pathways of neuroinflammation, neurotransmitter activity, and synaptic function. The predictive models exhibited great diagnostic performance, achieving 0.94 (95% CI: 0.85–0.98) and 0.96 (95% CI: 0.86–0.99) in the test set. …”

Maternal exposure to dim light at night induces behavioral alterations in the adolescent and adult offspring Wistar rat by Shellye González-González, Mariana Gutiérrez-Pérez, Mara A. Guzmán-Ruiz, Estefania Espitia-Bautista, Rosa María Pavón, Karla P. Estrada-Rodríguez, Alejandro Díaz-Infante R., Cecilia G. Guadarrama Gándara, Carolina Escobar, Natalí N. Guerrero-Vargas

“…Throughout development, microglia are responsible for the remodeling of diverse brain regions via synaptic pruning. During adolescence, this process occurs within the NAc, where immune-mediated remodeling directly impacts social play behavior.MethodsThis study investigated the effects of maternal exposure to DLAN or a light-dark cycle (LD) before (5 weeks) and during the gestational period (21–23 days) on the metabolism and behavior of offspring in adolescence and adulthood. …”

Clinical and molecular outcomes from the 5-Year natural history study of SSADH Deficiency, a model metabolic neurodevelopmental disorder by Itay Tokatly Latzer, Jean-Baptiste Roullet, Wardiya Afshar-Saber, Henry H. C. Lee, Mariarita Bertoldi, Gabrielle E. McGinty, Melissa L. DiBacco, Erland Arning, Melissa Tsuboyama, Alexander Rotenberg, Thomas Opladen, Kathrin Jeltsch, Àngels García-Cazorla, Natalia Juliá-Palacios, K. Michael Gibson, Mustafa Sahin, Phillip L. Pearl

“…GABA-metabolism in induced GABAergic neurons could be reversed using CRISPR correction of the pathogenic variants or mRNA transfection and SSADHD iPSCs were associated with excessive glutamatergic activity and related synaptic excitation. Conclusions Findings from the SSADHD Natural History Study converge with iPSC and animal model work focused on a common disorder within our IDDRC, deepening our knowledge of the pathophysiology and longitudinal clinical course of a complex neurodevelopmental disorder. …”
