Metabolomics reveals that CKI treatment leads to the accumulation of polyunsaturated fatty acids (PUFAs). Multi-omics integration uncovers CKI-mediated inhibition of the HIF-1α/SREBP1 axis, suppressing de novo lipogenesis (DNL), and downregulation of the PPARα/SLC47A1 pathway, impairing fatty acid oxidation and lipid efflux. This dual blockade results in intracellular PUFAs accumulation and elevated lipid peroxidation, triggering mitochondrial dysfunction and oxidative stress-induced cell death.</div></div><div><h3>Conclusion</h3><div>CKI, a clinically approved traditional Chinese medicine, as a potent metabolic disruptor that impairs breast cancer bone metastasis through coordinated reprogramming of lipid metabolism and preservation of bone integrity.</div></div>","PeriodicalId":20212,"journal":{"name":"Phytomedicine","volume":"148 ","pages":"Article 157323"},"PeriodicalIF":8.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
