The current focus is on understanding the signaling pathways of ferroptosis to precisely regulate the ferroptosis mechanism. For example, ferroptosis increases intracellular selenium content and synergistically activates transcription factors transcription factor AP-2 gamma and specificity protein 1 to promote glutathione peroxidase-4 expression (GPX4).

Ferroptosis is a form of cell death driven by the intracellular accumulation of iron. This is primarily characterised by a loss in endogenous antioxidant capacity and uncontrolled lipid peroxidation. Ferroptosis has been reported to underlie the pathology associated with several neurological and neurodegenerative conditions and has, therefore, become an attractive target for therapeutic intervention. Salicylaldehyde benzoylhydrazone (SBH) is a specialised hydrazone agent, known for its antibacterial and anticancer properties. It has robust metal-chelating capacity, with a particular affinity for complexing with iron and copper. The current study sought to investigate the potential of SBH to act as an anti-ferroptotic agent and to alleviate the neurotoxic and dysfunctional consequences of iron overload. We demonstrate that SBH can alleviate the death of HT22 hippocampal neurons, induced by exposure to the iron donor, ferric ammonium citrate (FAC). This was accompanied by a reduction in intracellular iron and lipid peroxidation, and alleviation of hallmark changes in gene expression indicative of ferroptosis. Using FAC-incubated zebrafish larvae as an in vivo model of iron overload, we reveal that SBH can reduce the mortality and toxicity associated with FAC exposure. Moreover, we report a FAC-mediated dysfunction in intrinsic sensorimotor reflex behaviour, which is restored by SBH. Taken together, our findings highlight SBH as an anti-ferroptotic agent and support its further investigation as a potential neurotherapeutic for conditions associated with iron dysregulation.</p>","PeriodicalId":652,"journal":{"name":"Journal of Molecular Neuroscience","volume":"75 2","pages":"77"},"PeriodicalIF":2.8,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12167254/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144293082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emerging evidence indicates that mitochondrial architecture undergoes substantial remodeling throughout cellular reprogramming processes. To explore the implications of mitochondrial dynamics in chemical-induced neuronal transdifferentiation, human foreskin fibroblasts (HFFs) were directly reprogrammed into functional neurons with our previously developed small molecule compound. The results showed that the mitochondrial morphology of HFFs shifted from tubular and reticular to fragmented shapes at an early stage of induced neurulation. Concurrently, gene and protein expression levels of the mitochondrial fission protein Drp1 was significantly increased in HFFs after induction. Both Drp1-specific siRNA and Drp1-GTPase inhibitor mdivi-1 treatment significantly attenuated the neuronal transdifferentiation of HFFs to neurons respectively, which can be attributed to the modulation of mitochondrial dynamics toward a fusion-dominant state through Drp1 suppression. Collectively, our experimental findings establish Drp1-dependent mitochondrial fission as a critical early requirement in the chemical reprogramming cascade that facilitates HFF transdifferentiation into neuronal lineages.

A comprehensive understanding of these factors is crucial for the development of effective treatments and ultimately a cure for this debilitating condition. In this review, we summarize key regulatory pathways involved in AD pathogenesis, emphasizing genetic factors such as the apolipoprotein E (APOE) gene and high-impact genetic mutations in amyloid precursor protein (APP) and presenilin 1 (PSEN1). We also explore significant epigenetic regulators, including DNA methylation, histone deacetylases (HDACs), and microRNAs (miRNAs), which modulate gene expression and contribute to disease progression. Furthermore, we discuss the interplay between genetic and epigenetic factors, highlighting their combined impact on β-amyloid deposition, tau pathology, neuroinflammation, and synaptic dysfunction.
