Vascular complications, particularly thrombosis, contribute significantly to MPN morbidity and mortality; however, the molecular mechanisms underlying endothelial dysfunction remain incompletely understood.</div><div>In this study, we investigated the effects of <em>JAK2</em>V617F-positive extracellular genomic materials (EGMs)—including cell-free DNA (cfDNA), and exosomes, derived from HEL cells—on endothelial inflammation, coagulation, and nucleic acid-sensing pathways to elucidate their contribution to MPN-associated vascular pathology. Human umbilical vein endothelial cells (HUVECs) were treated with <em>JAK2</em>V617F-positive EGMs and culture supernatant (CS). We assessed proliferation, apoptosis, <em>HMGB1</em> expression and release, cytokine secretion, nucleic acid-sensing pathway activation, and coagulation-related gene expression via RT-PCR, ELISA, and flow cytometry.</div><div>We have demonstrated that exosomes exhibited the most potent effects on endothelial activation, robust HMGB1 secretion and cytokine release, including IL-1β, IL-6, and MCP-1, indicating activation of early inflammation while cfDNA induced intracellular HMGB1 accumulation with limited extracellular release. We further demonstrate that <em>JAK2</em>V617F-positive EGMs activate nucleic acid sensing pathways (cGAS-STING and TLR9), leading to increased expression of proinflammatory mediators such as <em>NF-κB</em>, <em>IRF3</em>, and <em>IRF7</em>. The upregulation of coagulation-related genes (<em>F10, F3</em>, <em>F2RL1</em>) and adhesion molecules (<em>ICAM-1, TF</em>) confirmed that EGM exposure promotes a pro-thrombotic phenotype in ECs, mirroring the hypercoagulable state in MPN patients.</div><div>As our in vitro system lacks physiological conditions such as blood flow dynamics and immune cell interactions, further validation in patient-derived samples and in vivo models with varying <em>JAK2</em>V617F allele burdens is required. Nonetheless, these findings establish a mechanistic link between oncogenic EGMs and vascular complications in MPNs, highlighting their role in chronic inflammation and thrombosis. Targeting EGM-mediated endothelial dysfunction may offer a novel therapeutic approach to mitigate vascular complications in MPN patients.</div></div>","PeriodicalId":23064,"journal":{"name":"Thrombosis research","volume":"253 ","pages":"Article 109407"},"PeriodicalIF":3.4,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144724481","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}
