However, its clinical application is limited due to cardiotoxic side effects. Astragaloside IV (AS IV), one of the major compounds present in aqueous extracts of Astragalus membranaceus, possesses potent cardiovascular protective properties, but the underlying molecular mechanisms are unclear. Thus, the aim of this study was to investigate the effect of AS IV on DOX-induced cardiotoxicity (DIC). Our findings revealed that DOX induced pyroptosis through the caspase-1\/gasdermin D (GSDMD) and caspase-3\/gasdermin E (GSDME) pathways. AS IV treatment significantly improved the cardiac function and alleviated myocardial injury in DOX-exposed mice by regulating intestinal flora and inhibiting pyroptosis; markedly suppressed the levels of cleaved caspase-1, N-GSDMD, cleaved caspase-3, and N-GSDME; and reversed DOX-induced downregulation of silent information regulator 1 (SIRT1) and activation of the NLR family pyrin domain containing 3 (NLRP3) inflammasome in mice. The SIRT1 inhibitor EX527 significantly blocked the protective effects of AS IV. Collectively, our results suggest that AS IV protects against DIC by inhibiting pyroptosis through the SIRT1\/NLRP3 pathway. <\/jats:p>","DOI":"10.1142\/s0192415x24500198","type":"journal-article","created":{"date-parts":[[2024,3,16]],"date-time":"2024-03-16T02:02:12Z","timestamp":1710554532000},"page":"453-469","source":"Crossref","is-referenced-by-count":35,"title":["Astragaloside IV Alleviates Doxorubicin-Induced Cardiotoxicity by Inhibiting Cardiomyocyte Pyroptosis through the SIRT1\/NLRP3 Pathway"],"prefix":"10.1142","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3893-8013","authenticated-orcid":false,"given":"Wencong","family":"Tian","sequence":"first","affiliation":[{"name":"Department of General Surgery, Tianjin Union Medical Center, Tianjin 300122, P.
