Circular RNAs (circRNAs) are noncoding RNAs that can be used as diagnostic biomarkers and therapeutic targets for human diseases. In this study, we analysed the expression of hsa_circ_0008925 in human urinary renal tubular cells and investigated its role in renal fibrosis. Urinary samples were collected from CKD patients with varying degrees of renal fibrosis; renal tubular epithelial cells were isolated from the urinary samples using magnetic bead sorting. In patients with moderate\u2013severe renal fibrosis, the expression of hsa_circ_0008925 in urinary renal tubular epithelial cells was elevated compared to that in patients with no renal fibrosis to mild renal fibrosis. Spearman correlation analysis indicated that the hsa_circ_0008925 expression was positively correlated with serum creatinine (Scr, rs\u2009=\u20090.424, <jats:italic>p<\/jats:italic>\u2009=\u20090.031). The expression of hsa_circ_0008925 was elevated in TGF\u2010\u03b21\u2010treated HK\u20102 cells in\u00a0vitro. Silencing of hsa_circ_0008925 using siRNA inhibited TGF\u2010\u03b21\u2010induced fibrosis in HK2 cells. RNA pull\u2010down and mass spectrometric analyses indicated that serine\/arginine\u2010rich splicing factor 6 (SRSF6) is the downstream of hsa_circ_0008925. Silencing mmu_circ_0002215 and inhibiting SRSF6 alleviated renal fibrosis in a UUO model in\u00a0vivo. Inhibiting hsa_circ_0008925\/SRSF6 alleviated renal fibrosis in\u00a0vitro and in\u00a0vivo. These findings suggest that targeting the hsa_circ_0008925\/SRSF6 pathway could hold promise as a potential therapeutic strategy for treating renal fibrosis.<\/jats:p>","DOI":"10.1111\/jcmm.70335","type":"journal-article","created":{"date-parts":[[2025,1,12]],"date-time":"2025-01-12T13:34:03Z","timestamp":1736688843000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Renal
