After 1 week of hepatic maturation, followed by 1 week of exposure, the transcriptomic analysis showed lower liver transcription factor activity. It also revealed that 318 genes were differentially expressed between the control and 0.5-mM PA conditions. The 0.5-mM PA conditions were characterized by the downregulation of hepatic markers (liver transcription factors, phase I and phase II metabolism genes) of lipidic genes (metabolism and transport). In parallel, the 0.5-mM PA treatment upregulated several extracellular matrix genes (such as collagen genes). The physiopathological staining demonstrated no lipid accumulation in our model and confirmed the secretion of collagen in the 0.5-mM PA conditions. However, the production of albumin, the metabolic biotransformation by the cytochrome P450 enzymes, and the biliary acid concentrations were not altered by the PA treatments. Overall, our data illustrated the response to PA characterized by an early stage of dedifferentiation observed at the transcriptomic levels associated with a modification of the collagenic profile but without lipid accumulation.

Although previous studies have reported their toxic effects on fish, the underlying mechanisms behind their toxic effects are yet to be identified. This study evaluated the impact of ZnO NPs on marine medaka's survival, heart rates (<i>Oryzias melastigma</i>), and the expression of genes linked to neurotoxicity and cardiovascular toxicity. Marine medaka samples were exposed to ZnO NPs at varying concentrations: 0.01, 0.1, 1, and 10 mg/L. Survival rates and heart rates were monitored on the 12th day postfertilization. Gene expression related to neurotoxicity (<i>α-tubulin</i>, <i>elavl3</i>, <i>gap43</i>, <i>gfap</i>) and cardiovascular toxicity (<i>cdh2</i>, <i>atp2a1</i>, <i>cacna1da</i>, <i>crhr1</i>, <i>ahrra</i>, <i>arnt2</i>) was assessed by performing real-time polymerase chain reaction. The survival rate of marine medaka samples was not significantly impacted by exposure to up to 1 mg/L of ZnO NPs; however, exposure to 10 mg/L of ZnO NPs resulted in a 60% reduction in survival rate. The heart rate of the samples did not significantly change across all concentrations. High ZnO NP concentrations (10 mg/L) significantly suppressed the expression of neurotoxic and cardiotoxic genes, including <i>elavl3</i> and <i>gfap</i>. ZnO NPs exhibited dose-dependent toxic effects on the marine medaka samples by affecting the expression of genes related to neurological and cardiovascular functions. These findings underscore the potential risks of ZnO NPs to aquatic organisms. The distinct toxic actions of ZnO NPs and dissolved ions complicate the interpretation of results, as this study did not measure ion release, a critical factor in understanding NP toxicity. Moreover, ZnO NPs may cause oxidative stress and disrupt cellular pathways. Furthermore, without distinguishing between NP and ion effects, it is challenging to determine the exact cause of toxicity. These findings highlight the need for future studies to measure dissolved ions and particles separately to clarify their contributions to toxicity, where the mechanisms of action are still debated.</p>\u0000 </div>","PeriodicalId":15242,"journal":{"name":"Journal of Applied Toxicology","volume":"45 3","pages":"452-459"},"PeriodicalIF":2.7,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142557927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, research on the toxicological effects of MDA-19 remains scarce. In this study, we examined the effects of MDA-19 on neurodevelopment, behavior, oxidative stress, and metabolomics by exposing zebrafish embryos to MDA-19 solutions with concentrations of 1, 10, and 20 mg/L over 5 days. Results revealed that exposure to 10 and 20 mg/L of MDA-19 accelerated hatching in zebrafish embryos but led to reduced body length without affecting mortality or malformation. Furthermore, exposure to all concentrations of MDA-19 resulted in diminished swimming ability and reduced activity time in zebrafish. Transgenic zebrafish (<i>hb9</i>-GFP) exposed to MDA-19 exhibited impaired development of spinal motor neurons. Notably, exposure to 20 mg/L MDA-19 increased the levels of reactive oxygen species (ROS) in zebrafish and elevated the activity of antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT), while the levels of the lipid oxidation product malondialdehyde (MDA) remained unaffected. Nontargeted metabolomics analyses showed that MDA-19 interfered with multiple metabolic pathways affecting energy metabolism, such as alanine, aspartate, and glutamate metabolism; the citric acid cycle (TCA cycle), pantothenate, and coenzyme A biosynthesis; and purine metabolism.
