Isoimperatorin (ISO), a natural coumarin, possesses nephroprotective properties, yet its effect on cuproptosis remains unknown. Herein, this study demonstrated that ISO administration effectively attenuated renal tubular injury, improved renal function, and reduced copper accumulation in a mouse IRI model. In vitro, ISO alleviated hypoxia/reoxygenation-induced oxidative stress, mitochondrial damage, and cuproptosis susceptibility. Single-cell transcriptomic (scRNA-Seq) analysis revealed that cuproptosis-related genes (e.g. Fdx1 and Slc31a1) exhibited transcriptional alterations. Through RNA sequencing and molecular interaction assays, this research identified dihydrolipoamide S-acetyltransferase (DLAT) as a binding partner of ISO. DLAT overexpression attenuated the protective effects of ISO, whereas the copper chelator tetrathiomolybdate (TTM) partially recapitulated its action. In vivo, ISO and TTM both suppressed IRI-induced DLAT, FDX1, and CTR1 upregulation. Collectively, our findings suggest that ISO attenuates cuproptosis susceptibility through DLAT, providing a mechanistic rationale for targeting the copper-DLAT axis in ischemic kidney injury.</p>","PeriodicalId":50335,"journal":{"name":"International Journal of Biochemistry & Cell Biology","volume":" ","pages":"107072"},"PeriodicalIF":3.5,"publicationDate":"2026-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149372066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the precise role and molecular mechanism of ginsenoside Rh1 (Rh1) in liver fibrosis remain largely obscure. This study investigated the anti-fibrotic mechanism of Rh1, focusing on ferroptosis. In vitro, Rh1 dose-dependently suppressed the viability of activated hepatic stellate cells (HSCs) and concurrently induced key ferroptosis features. In vivo, Rh1 administration markedly attenuated carbon tetrachloride-induced liver fibrosis, improved histological architecture, and restored liver function. Mechanistically, transcriptomic analysis and molecular validation identified SLC7A11, a core regulator of ferroptosis, as a binding partner of Rh1. Rescue experiments confirmed that the pro-ferroptotic and anti-fibrotic effects of Rh1 were functionally dependent on SLC7A11 inhibition. In conclusion, our findings demonstrated that ginsenoside Rh1 alleviated liver fibrosis by targeting SLC7A11 to promote the ferroptosis in cultured HSCs, unveiling a novel pharmacological mechanism.
