In addition to chronological age, anticancer therapies can accelerate this process. Doxorubicin, an anthracycline class antitumor drug, is known to have significant cardiac toxicity including cardiac aging, but the underlying mechanisms remain incompletely understood. In this study, we identified that CD47 was significantly increased in aged hearts through bioinformatic analyses. We next established a doxorubicin\u2010induced cardiac aging model in mice. Doxorubicin increased p53, p16, and p21 expression in mouse hearts, accompanied by marked CD47 upregulation. Similar effects were observed in AC16 cardiomyocytes, in which doxorubicin induced CD47 expression and a senescence\u2010like phenotype, including increased p16 and p21 levels and SA\u2010\u03b2\u2010gal positivity. Blocking CD47 with a specific antibody attenuated doxorubicin\u2010induced cardiac aging and cardiomyocyte senescence in\u00a0vivo and in\u00a0vitro, and improved doxorubicin\u2010induced cardiac dysfunction. These results identify CD47 as a functional mediator of doxorubicin\u2010induced cardiac aging and support CD47 blockade as a potential strategy to mitigate anthracycline\u2010associated cardiac dysfunction.<\/jats:p>","DOI":"10.14814\/phy2.71111","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T08:05:21Z","timestamp":1790323521000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>CD47<\/scp>\n
