Docking and network analyses revealed that fucoxanthin interacted with seven major proteins related to inflammation and senescence. Senescence-associated β-galactosidase and matrix metalloproteinases were downregulated by fucoxanthin following exposure to PM<sub>2.5</sub>. Conclusively, fucoxanthin attenuates the cellular oxidative stress caused by PM<sub>2.5</sub> and suppresses inflammatory responses and senescence, thereby implying its potential in alleviating PM<sub>2.5</sub>-induced skin damage.</p>","PeriodicalId":23177,"journal":{"name":"Toxicology Mechanisms and Methods","volume":" ","pages":"809-822"},"PeriodicalIF":2.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144062097","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}
