This study mainly aimed to evaluate the role of H<sub>2</sub>S in postnatal CM proliferation and its regulating molecular mechanisms. We found that sodium hydrosulfide (NaHS, the most widely used H<sub>2</sub>S donor, 50-200 μM) increased neonatal mouse primary CM proliferation in a dose-dependent manner<i> in vitro</i>. Consistently, exogenous administration of H<sub>2</sub>S also promoted CM proliferation and increased the total number of CMs at postnatal 7 and 14 days <i>in vivo</i>. Moreover, we observed that the protein expression of SIRT1 was significantly upregulated after NaHS treatment. Inhibition of SIRT1 with EX-527 or si-SIRT1 decreased CM proliferation, while enhancement of the activation of SIRT1 with SRT1720 promoted CM proliferation. Meanwhile, pharmacological and genetic blocking of SIRT1 repressed the effect of NaHS on CM proliferation. Taken together, these results reveal that H<sub>2</sub>S plays a promotional role in proliferation of CMs <i>in vivo</i> and <i>in vitro</i> and SIRT1 is required for H<sub>2</sub>S-mediated CM proliferation, which indicates that H<sub>2</sub>S may be a potential modulator for heart development in postnatal time window.</p>\u0000<p></p>","PeriodicalId":13711,"journal":{"name":"International heart journal","volume":"15 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141187982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
