Here, we investigated the functional role of ephrin type-B receptor 1 (EPHB1), a member of the ephrin receptor family, in ESCC metastasis. Integrated analyses of RNA-sequencing data and publicly available databases demonstrated that EPHB1 expression is significantly upregulated in ESCC tissues and is positively associated with advanced tumor grade and poor patient survival. Gain- and loss-of-function assays revealed that EPHB1 knockdown markedly inhibited ESCC cell migration, invasion, and epithelial-mesenchymal transition (EMT), whereas EPHB1 overexpression exerted the opposite effects. Consistently, in vivo metastasis assays further confirmed that EPHB1 promotes lung metastasis of ESCC cells. Mechanistically, we identified SRY-box transcription factor 2 (SOX2) as a critical upstream regulator that directly binds to the EPHB1 promoter and transcriptionally activates its expression. Rescue experiments demonstrated that SOX2-induced EMT and invasive capacity are largely mediated through EPHB1.

Direct breast cancer evidence supports colonization of adipocyte-rich human bone explants and links adipocyte-derived signals with tumor migration, whereas several metabolic, dormancy, immune, and senescence pathways remain supported mainly by animal, in vitro, or other-cancer studies. Tumor cells, rather than bone marrow adipocytes, can increase fatty-acid transport, activation, and oxidation in response to adipocyte-derived lipids. Chemotherapy and aromatase inhibition can increase marrow adiposity, alter stromal lineage commitment, and promote bone loss; however, a direct causal pathway from treatment-induced BMAT expansion to breast cancer persistence, resistance, or relapse has not been established clinically.

Among the most important host contributors, platelets have emerged as active facilitators of metastatic dissemination, supporting the survival of circulating tumor cells, immune evasion, endothelial arrest, extravasation, and early colonization. More recently, platelet-derived mitochondrial transfer has been recognized as a novel mechanism by which platelets may enhance tumor aggressiveness through metabolic reprogramming. This review critically synthesizes the current literature on platelet-mediated mitochondrial transfer in cancer, with emphasis on its biological mechanisms, functional consequences, and translational implications. Emerging evidence in selected osteosarcoma and triple-negative breast cancer models indicates that activated platelets can donate functional mitochondria to cancer cells through direct contact and microparticle-mediated pathways, potentially increasing oxidative phosphorylation, ATP production, redox adaptability, proliferative capacity, and migratory behavior. Mechanistically, platelet mitochondrial transfer may involve pathways linked to mitochondrial quality control and trafficking, including PINK1/Parkin-MFN2 signaling, while also intersecting with broader platelet-tumor crosstalk that promotes epithelial-mesenchymal transition, anoikis resistance, and immune escape. In parallel, platelet-derived mitochondrial cargo and related extracellular vesicle signatures may offer new opportunities for liquid biopsy-based biomarker development. However, major challenges remain, including the need for rigorous in vivo validation, discrimination of intact mitochondria from fragmented mitochondrial material, and clarification of context-dependent effects across tumor types. Collectively, platelet-derived mitochondrial transfer represents an emerging layer of intercellular communication that may link thrombosis, metabolism, and metastasis, and it offers promising avenues for both biomarker discovery and therapeutic intervention.</p>","PeriodicalId":10267,"journal":{"name":"Clinical & Experimental Metastasis","volume":"43 5","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148788909","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}
