Building on our previous findings that delineated an RBM15/YTHDF2/IGF2BP3 regulatory axis in m6A-mediated RNA metabolism in HCC, this study further explores the posttranscriptional regulation of VEGFA by HBV. By MeRIP-qPCR and integrating MeRIP-seq data, we discovered that HBV enhances m6A methylation of VEGFA mRNA. Comprehensive cellular and molecular biology experiments demonstrated that HBV induces the upregulation of IGF2BP3, which serves as a key “reader” that recognizes and stabilizes VEGFA mRNA in an m6A methylation-dependent manner. This stabilization leads to elevated VEGFA expression, promoting enhanced cellular functions such as HUVEC migration and tube formation. Furthermore, in an HBV-associated HCC xenograft model, IGF2BP3 knockdown resulted in decreased VEGFA expression and inhibited tumor growth. This study expands our understanding of HBV-driven angiogenesis and identifies the IGF2BP3-VEGFA axis as a potential therapeutic target for antiangiogenic strategies in HBV-related HCC.</p>\u0000 </div>","PeriodicalId":16354,"journal":{"name":"Journal of Medical Virology","volume":"97 5","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143856740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
