However, there are no data on the role of circSLCO3A1 in ALI and the underlying mechanism.</p><p><strong>Objective: </strong>ALI-like cell injury was induced by stimulating human pulmonary alveolar epithelial cells (HPAEpiCs) using lipopolysaccharide (LPS). The expression of circSLCO3A1, miR-424-5p and high mobility group box 3 (HMGB3) was detected by quantitative real-time polymerase chain reaction. Cell viability and cell apoptosis were assessed by cell counting kit-8 (CCK-8) assay and flow cytometry analysis, respectively. Enzyme-linked immunosorbent assay was performed to determine the production of interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α) and monocyte chemotactic protein 1 (MCP-1). Caspase-3 activity was detected by caspase-3 activity assay. Protein expression of inducible NOS (iNOS), cyclooxygenase-2 (COX2), p-p65 and p65 was analyzed by Western blot. The interactions among circSLCO3A1, miR-424-5p and HMGB3 were identified by dual-luciferase reporter assay, RNA immunoprecipitation assay and RNA pull-down assay.</p><p><strong>Results: </strong>CircSLCO3A1 and HMGB3 expression were significantly increased, while miR-424-5p was decreased in LPS-treated HPAEpiCs and the serum of septic ALI patients in comparison with controls. CircSLCO3A1 knockdown assuaged LPS-induced HPAEpiC inflammation and apoptosis. Besides, circSLCO3A1 targeted miR-424-5p and regulated LPS-triggered HPAEpiC inflammation and apoptosis by binding to miR-424-5p. Under the treatment of LPS, miR-424-5p mediated HPAEpiC disorders by targeting HMGB3. Importantly, circSLCO3A1 modulated HMGB3 production by interacting with miR-424-5p.</p><p><strong>Conclusion: </strong>CircSLCO3A1 absence assuaged LPS-induced HPAEpiC inflammation and apoptosis through the miR-424-5p/HMGB3 axis.</p><p><strong>Highlights: </strong>CircSLCO3A1 expression was upregulated in LPS-induced HPAEpiCs and sepsis-induced ALI patients.CircSLCO3A1 depletion protected against LPS-induced HPAEpiC disorders.CircSLCO3A1 bound to miR-424-5p in HPAEpiCs.MiR-424-5p targeted HMGB3 in HPAEpiCs.CircSLCO3A1 regulated HMGB3 expression through miR-424-5p.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13273-023-00341-6.</p>","PeriodicalId":18683,"journal":{"name":"Molecular & Cellular Toxicology","volume":" ","pages":"1-12"},"PeriodicalIF":1.7,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10211294/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10091312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
