Cancer cells release a substantial number of EVs that carry distinct cargo molecules, including oncogenic proteins, DNA fragments, and various RNA species. Upon uptake, these cargo molecules profoundly influence the biology of both normal and cancerous cells. This review consolidates the understanding of how EVs promote tumorigenesis by regulating processes such as proliferation, migration, metastasis, angiogenesis, stemness, and immunity. The exploration of EVs as a non-invasive method for cancer detection holds great promise, given that different cancer types exhibit unique protein and RNA signatures that can serve as valuable biomarkers for early diagnosis. Furthermore, growing interest exists in the potential bioengineering EVs for use as prospective therapeutic tools for cancer treatment.</div></div>","PeriodicalId":93920,"journal":{"name":"Cancer pathogenesis and therapy","volume":"3 2","pages":"Pages 109-119"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140794287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
