The kidney protective activity of celastrol is mainly exerted through anti-inflammatory, and antioxidant effects. However, celastrol causes dose-dependent kidney toxicity, which results in increased risks of mortality among patients. This study aimed to develop a kidney organoid-based prediction system to assess the safety and efficacy of celastrol in reducing cisplatin-induced nephrotoxicity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We investigated the ability of celastrol to reduce cisplatin-induced nephrotoxicity using kidney organoids. Kidney organoids were cultured and characterized, exhibiting renal tubular and glomerular structures and expressing specific kidney markers such as NPHS1, CD31, LTL, and SLC12A1. Data were obtained from <jats:italic>in vitro<\/jats:italic> experiments in which kidney organoids were exposed to therapeutically relevant concentrations or a toxic dosing profile of cisplatin and celastrol, to assess their impact on cell viability using flow cytometry and Acridine Orange\/Propidium Iodide (AO\/PI) staining. In addition, RNA-seq analyses were performed to determine the mechanisms of celastrol function in the kidney.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Kidney organoids exposed to 50\u00a0\u00b5M cisplatin showed significantly increased cell death (only 0.37% cells with normal cell structure), whereas celastrol under 5\u00a0\u00b5M (56% cells with normal cell structure) showed significantly less nephrotoxicity than cisplatin. The protective effects of celastrol against cisplatin-induced nephrotoxicity were further investigated by treating the organoids with both compounds. The results demonstrated that 2\u00a0\u00b5M celastrol reduced cisplatin-induced nephrotoxicity by downregulating SNORD3A and HIST1H3A gene levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study highlights the potential of celastrol as a protective compound against cisplatin-induced kidney damage and emphasizes the importance of using advanced models, such as iPSC-derived kidney organoids, to predict therapeutic effect and nephrotoxic concentrations of novel drugs.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fphar.2025.1464525","type":"journal-article","created":{"date-parts":[[2025,3,27]],"date-time":"2025-03-27T18:42:15Z","timestamp":1743100935000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Celastrol reduces cisplatin-induced nephrotoxicity by downregulating SNORD3A level in kidney organoids derived from human iPSCs"],"prefix":"10.3389","volume":"16","author":[{"given":"Chongayng","family":"Shen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qizheng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xun","family":"Ye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huayang","family":"Xing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengjie","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heying","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunjie","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingliang","family":"You","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,3,27]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2668","DOI":"10.2337\/db18-0124","article-title":"Histone H3 serine 10 phosphorylation facilitates endothelial activation in diabetic kidney disease","volume":"67","author":"Alghamdi","year":"2018","journal-title":"Diabetes"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1341","DOI":"10.1016\/s0278-5846(01)00192-0","article-title":"Celastrol, a potent antioxidant and anti-inflammatory drug, as a possible treatment for Alzheimer's disease","volume":"25","author":"Allison","year":"2001","journal-title":"Prog.
