Xin-Zi-Sheng-Wan Decoction Alleviates Hyperuricemia-Induced Renal Injury by Modulating SPP1-CD44-Mediated Macrophage Infiltration and SRC/FAK/β-Catenin Signaling Pathway


ABSTRACT: Aim of the study This study aimed to evaluate the therapeutic efficacy of XZSWD against HUA-induced kidney injury and to elucidate the molecular pathways involved. Methods UPLC-QTOF/MS was used to identify compounds in XZSWD and medicated serum. A HUA mouse model was induced by potassium oxonate (PO) and hypoxanthine (HX) to evaluate the therapeutic effects of XZSWD on renal injury. RNA-Seq and CIBERSORT were applied to analyze gene expression and immune infiltration. Key signaling pathways were validated by qRT-PCR, Western blot, immunofluorescence, and flow cytometry. A THP-1/HK-2 co-culture system combined with SPP1 overexpression and knockdown was used to explore the molecular mechanisms underlying XZSWD’s anti-inflammatory and anti-fibrotic effects. Results 99 compounds were identified in XZSWDS. XZSWD reduced serum uric acid, improved renal function, and suppressed inflammation in HUA mice. RNA-Seq and CIBERSORT revealed downregulation of macrophage-related genes and enhanced mixed M1/M2 polarization. XZSWD inhibited the SPP1–CD44 axis and SRC/FAK/β-Catenin signaling, reducing Epithelial–Mesenchymal Transition (EMT) and Extracellular Matrix (ECM) deposition. In vitro, XZSWD suppressed uric acid-induced EMT and macrophage migration, polarization; these effects were reversed by SPP1 overexpression and enhanced by SPP1 knockdown, indicating SPP1 as a critical therapeutic target. Conclusions The XZSWD alleviates hyperuricemia-induced renal injury by effectively suppressing macrophage-mediated inflammation through coordinated regulation of the SPP1–CD44 axis and the SRC/FAK/β-Catenin signaling network.
