The liver is the major organ responsible for nutrient metabolism, exogenous substance detoxification and biotransformation of medicines containing nanoparticles. Hence, it is urgent to further understand the principles and potential mechanisms of hepatic effects on NiNPs administration. In this study, we explored the liver impacts in male C57\/BL6 mice through intraperitoneal injection with NiNPs at doses of 10, 20 and 40 mg\/kg\/day for 7 and 28 days. The results showed that NiNPs treatment increased serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and induced pathological changes in liver tissues. Moreover, hepatic triglyceride (TG) content and lipid droplet deposition identified via de novo lipogenesis (DNL) progression were enhanced after NiNPs injection. Additionally, sustained NiNPs exposure induced a remarkable hepatic inflammatory response, significantly promoted endoplasmic reticulum stress (ER stress) sensors Ire1\u03b1, Perk and Atf6, and activated the occurrence of liver cell apoptosis. Overall, the research indicated that NiNPs exposure induced liver injury and disturbance of lipid metabolism. These findings revealed the public hazard from extreme exposure to NiNPs and provided new information on biological toxicity and biosafety evaluation.<\/jats:p>","DOI":"10.3390\/molecules28155757","type":"journal-article","created":{"date-parts":[[2023,7,31]],"date-time":"2023-07-31T02:13:32Z","timestamp":1690769612000},"page":"5757","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Nickel Nanoparticles Induced Hepatotoxicity in Mice via Lipid-Metabolism-Dysfunction-Regulated Inflammatory Injury"],"prefix":"10.3390","volume":"28","author":[{"given":"Shuang","family":"Zhou","sequence":"first","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"},{"name":"Beijing Institute of Technology, School of Life Science, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hua","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Song","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Da","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changlei","family":"Wei","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Guo","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueying","family":"He","sequence":"additional","affiliation":[{"name":"Beijing Institute of Medical Device Testing, Beijing Center for Testing and Research of Medical Biological Protective Equipment, Beijing 101111, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0720-4052","authenticated-orcid":false,"given":"Yulin","family":"Deng","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology, School of Life Science, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1821","DOI":"10.1039\/D0MA00807A","article-title":"Nanomaterials: A review of synthesis methods, properties, recent progress, and challenges","volume":"2","author":"Baig","year":"2021","journal-title":"Mater.
