This comprehensive approach was undertaken to elucidate the mechanism by which YPG inhibits the senescence of ASMCs.</p><p><strong>Results: </strong>The results of in vivo and in vitro experiments demonstrated that SIRT1 overexpression and YPG inhibited the senescence of ASMCs and significantly reduced P16 and P21 proteins, as well as cellular SASP (Interleukin-1β (IL-1β), Interleukin-4 (IL-4), and Interleukin-17 (IL-17)). Moreover, YPG demonstrated a substantial reduction in histopathological alterations in BA rats. Furthermore, the study observed a decline in Malondialdehyde (MDA) expression, concomitant with an augmentation in the expression levels of SIRT1, Nrf2, oxygenase-1 (HO-1), Superoxide dismutase (SOD), and Catalase (CAT). It substantiated the interaction of SIRT1 with Nrf2 and the decrease in the expression level of Nrf2 acetylation.</p><p><strong>Conclusions: </strong>These results suggest that YPG can activate the SIRT1/Nrf2/HO-1 signaling pathway by regulating the expression level of SIRT1 to regulating the acetylated expression level of Nrf2, to inhibit the senescence of ASMCs, leading to the treatment of asthma.</p>","PeriodicalId":49131,"journal":{"name":"Respiratory Research","volume":"26 1","pages":"266"},"PeriodicalIF":5.8,"publicationDate":"2025-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12400603/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144975994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
