The zebrafish (<em>Danio rerio</em>) has gained prominence in BoNT research, particularly due to its genetic tractability and suitability for high-throughput screening, making it an effective model for studying BoNT effects at molecular, cellular, and behavioral levels. This review explores the role of zebrafish in neurotoxin research, highlighting its utility in studying BoNT toxicity, synaptic mechanisms, gene silencing applications, and therapeutic interventions. We discuss zebrafish-based studies that provide insights into BoNT-induced behavioral and cognitive effects. Additionally, we examine how zebrafish facilitate high-throughput screening for BoNT-related compounds and antitoxins. Despite the contributions of zebrafish-based models in neurotoxicology, further research is needed to fully elucidate BoNT mechanisms and optimize a putative therapeutic potential.</div></div>","PeriodicalId":317,"journal":{"name":"Food and Chemical Toxicology","volume":"205 ","pages":"Article 115704"},"PeriodicalIF":3.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies highlight the involvement of Nuclear Receptor Coactivator 4 (NCOA4)-mediated ferritinophagy and ferroptosis in this process, but their specific roles remain unclear. In this study, PC12 cells were treated with aluminum maltolate [Al(mal)<sub>3</sub>], with or without deferoxamine (DFO), a ferroptosis inhibitor, to explore the role of ferroptosis in aluminum-induced toxicity. Ferritinophagy was further examined using 3-Methyladenine (3-MA) and small interfering RNA (siRNA) targeting NCOA4. Al(mal)<sub>3</sub> treatment increased intracellular iron, reactive oxygen species (ROS), and malondialdehyde (MDA) levels, while reducing glutathione (GSH), mitochondrial membrane potential (MMP), and glutathione peroxidase 4 (GPX4) expression—hallmarks of ferroptosis. DFO and inhibition of ferritinophagy reversed these effects. Moreover, suppression of NCOA4 restored ferritin levels and improved iron homeostasis. These findings suggest that aluminum may activate NCOA4-mediated ferritinophagy, leading to disrupted iron metabolism, oxidative stress, and ferroptosis in neuronal cells, thereby contributing to its neurotoxic effects.</div></div>","PeriodicalId":317,"journal":{"name":"Food and Chemical Toxicology","volume":"205 ","pages":"Article 115699"},"PeriodicalIF":3.5,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144858752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exposure to environmentally relevant TCS concentrations (0–100 μM) revealed dose-dependent toxicity. Cell viability significantly decreased at more than 10 μM TCS, while migration was impaired at concentrations as low as 1 μM. RNA-sequencing (RNA-seq) and Chromatin immunoprecipitation sequencing (ChIP-seq) analyses of cells exposed to 10 μM TCS showed substantial redistribution of enhancer regions (marked by H3K27ac). Motif enrichment analysis identified TCF12 as the most significantly affected transcription factor among five differentially enriched factors. Further investigation demonstrated that TCS exposure upregulated both TCF12 and its target gene RASSF8. The functional relationship between these factors was confirmed through TCF12 knockdown experiments, which decreased RASSF8 expression and partially reversed TCS-induced migration inhibition. Luciferase reporter assays verified direct binding of TCF12 to the RASSF8 promoter region.
