This study compared the biokinetics of partially soluble Fe<sub>2</sub>O<sub>3</sub> and poorly soluble TiO<sub>2</sub> to investigate how biotransformation influences lung clearance kinetics. Test nanoparticles (140 µg/rat) were instilled into the lungs of rats, and quantitative and qualitative assessments were performed on samples collected from the lungs on days 0, 1, 7, 14, 28, and 90 post-instillation. Notably, this study focused on the biokinetics of particulate forms within the lungs to specifically address particokinetics. Fe<sub>2</sub>O<sub>3</sub> exhibited biphasic clearance kinetics, with rapid clearance in the early phase (days 0 to 14; half-life of 13 days) and slow clearance in the late phase (days 14 to 90; half-life 123 days). This biphasic pattern was attributed to the erosion of Fe<sub>2</sub>O<sub>3</sub> into smaller, nanometer-sized particles, approximately 40% of which persisted in the lungs for over 3 months. These retained particles showed reduced oxidative potential and were sequestered in ferritin protein, mitigating potential toxicity. In contrast, TiO<sub>2</sub> exhibited a monophasic clearance pattern with a half-life of 88 days and did not exhibit particle degradation. These findings underscore the critical role of biotransformation in understanding the long-term safety and toxicity of inhaled nanomaterials, highlighting the need for comprehensive studies to assess their biological fate and potential risks. Further research should focus on potential adverse effects due to particle overload, interactions with biomolecules, and disruptions in metal homeostasis.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"35 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ferroptosis, a recently characterized form of iron-dependent cell death, is related to a wide range of liver diseases. Ferritinophagy as a novel selective form of autophagy functions in iron processing is essential to induce ferroptosis. Poly(rC)-binding protein 1 (PCBP1) is an iron chaperone involved in iron loading to ferritin. Nevertheless, the potential health risk caused by TBBPA in mammals is unknown. Thus, this study is conducted to explore the molecular mechanism of TBBPA-induced liver injury and the unique role of PCBP1 in it. In this study, we found that TBBPA exposure caused hepatic pathological injury and hepatocyte mitochondrial morphological changes, such as decreased or absent mitochondrial crest, ruptured mitochondrial membranes and mitochondrial shrinkage. The result showed that TBBPA exposure exacerbated glutathione depletion and lipid peroxidation, which are hallmarks of ferroptosis. Consistent with the results in vivo, TBBPA exposure activated ferritinophagy and upregulated indicators related to ferroptosis in hepatocytes. Of note, overexpression of PCBP1 inhibited TBBPA-induced ferroptosis by reducing overstimulated ferritinophagy. Here, we uncover a new mechanism whereby TBBPA triggers hepatocyte ferroptosis through the activation of ferritinophagy. Of note, we identify PCBP1 as critical for liver iron homeostasis, link this molecule to liver disease.

Moreover, in addition to optimizing the electronic structure of Fe<sub>2</sub>O<sub>3</sub> and improving the charge transfer efficiency, the presence of oxygen vacancies (O<sub>v</sub>) provides active sites that enhance the adsorption and dissociation of NO<sub>3</sub><sup>−</sup> and reduce the energy barrier of the reaction step. This study develops a new method for preparing electrode materials that exhibit low energy consumption and high performance through a dual modulation strategy involving morphological regulation and vacancy engineering. The developed strategy also provides a broader technical route for the activity enhancement of other metal oxide catalysts.</div></div>","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"494 ","pages":"Article 138514"},"PeriodicalIF":12.2,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
