Notably, bottled water has been recognised as a major daily source of NP exposure. However, the associations between NP exposure and NAFLD onset, as well as the mechanistic basis, remain unclear. To investigate this, we analysed data from the National Health and Nutrition Examination Survey (NHANES) 2013–2016 cycles, using daily bottled water intake to estimate NP exposure and the hepatic steatosis index (HSI) as an indicator of liver fat accumulation. Animal and cellular experiments were conducted to evaluate NP-induced hepatic alterations. Additionally, transcriptomic analysis of liver tissues was performed, and integration with DisGeNET and the Comparative Toxicogenomics Database (CTD) enabled bioinformatic analyses and identification of key regulatory pathways. Epidemiological results revealed a significant positive correlation between bottled water consumption and HSI. Experimental findings demonstrated that NP exposure induced liver vacuolisation, oxidative damage, metabolic disruption, and inflammation in both in vivo and in vitro models. Transcriptomic and database integration revealed that NP exposure suppressed the PPAR signalling pathway, particularly by downregulating PPARγ expression, with excessive ROS generation likely contributing to this inhibition. These results were summarised in an adverse outcome pathway (AOP) framework, illustrating how NP exposure may impair PPARγ signalling and promote hepatic lipid accumulation. In conclusion, this study provides evidence that environmental NP exposure may be a contributing factor to NAFLD development and highlights the potential public health impact of the intake of NPs from bottled water.</div></div>","PeriodicalId":23159,"journal":{"name":"Toxicology","volume":"516 ","pages":"Article 154194"},"PeriodicalIF":4.8,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144086852","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}

Notably, endothelial microparticles (EMPs) isolated from 1-NP-treated HUVECs (N-EMPs) exhibited distinct biological effects compared to control EMPs (C-EMPs). N-EMPs suppressed trophoblast viability, proliferation, invasion, and migration, correlating with N-cadherin downregulation and E-cadherin upregulation. Mechanistically, ferroptosis emerged as the primary driver of N-EMPs-induced trophoblast dysfunction, evidenced by reactive oxygen species (ROS) accumulation, glutathione depletion, elevated malondialdehyde and Fe²⁺ levels, and mitochondrial oxidative stress. Crucially, glutathione peroxidase 4 (GPX4) was identified as a central regulator, with its expression significantly downregulated by N-EMPs. Overexpression of GPX4 reversed ferroptosis markers (restoring GSH/SOD, reducing MDA/Fe²⁺) and rescued trophoblast viability, migration, and invasiveness. These findings establish a previously unrecognized pathogenic cascade wherein 1-NP triggers endothelial injury, releasing cytotoxic EMPs that propagate ferroptosis-dependent trophoblast dysfunction via GPX4 suppression.

Previous studies on the ability of PAHs to induce the pathological progression of liver steatosis have been limited to the analysis of individual PAHs. The aim of this study was therefore to examine the effects of a mixture of PAHs whose composition closely recapitulates that of contaminated food. The PAH mixture elicited both a steatohepatitis-like state in steatotic WIF-B9 hepatocytes (100 nM for 72 hours) and the progression of steatohepatitis in rats fed a lipid-enriched diet (0.8 mg/kg for 90 days). The PAH mixture induced transient necroptosis at 5 hours followed by a gradual increase in cellular apoptosis. PAH metabolism-dependent necroptosis appeared to be responsible for the development of the secondary apoptosis. Hepatocyte exposure induced a necroptosis-dependent release of extracellular vesicles (EVs), that appeared to be protective against necroptosis; however, those necroptotic EVs triggered apoptosis in recipient hepatocytes. Blocking of ASGR EV receptors with asialofetuin inhibited the interaction of EVs with hepatocytes and hence apoptosis. In conclusion, EV release seems to be crucial to avoid necroptosis, but inhibition of EV uptake can protect against apoptosis.</div></div>","PeriodicalId":23159,"journal":{"name":"Toxicology","volume":"516 ","pages":"Article 154184"},"PeriodicalIF":4.8,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144086851","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}

However, the mechanisms by which Sb exerts toxicological effects on pancreatic islet β-cells are still not clear. In this investigation, Sb exposure significantly inhibited rat pancreatic islet β-cell-derived RIN-m5F cell viability and insulin secretion, while inducing mitochondria-dependent apoptotic signals, inclusive of increased apoptotic cell populations, caspase-3 activity, the expression of PARP and caspase-3/-7/-9, and mitochondrial dysfunction.
