Liuwei Dihuang Decoction (LWDHD) has been clinically established as an effective treatment for CKD, demonstrating anti-inflammatory, antioxidant, and antifibrotic effects. However, the specific molecular mechanisms underlying the therapeutic effectiveness of LWDHD remain unknown.Aim: Prediction of key active ingredients, targets, and mechanistic pathways of LWDHD in RF treatment.Materials and Methods: The bioactive components of LWDHD were identified and quantified using ultra-performance liquid chromatography-tandem quadrupole mass spectrometry (UHPLC-MS/MS). A network pharmacology approach was employed to predict the key targets of these bioactive components. A rat model of renal tubulointerstitial fibrosis was created through unilateral ureteral obstruction (UUO). Rats were divided into six groups: sham operation, UUO, low-dose LWDHD (LW-L), medium-dose LWDHD (LW-M), high-dose LWDHD (LW-H), and enalapril group. Continuous gavage of treatments was administered for 2 weeks. The renal tissues were histopathologically assessed, including HE, Masson’s trichrome, and Sirius red staining, immunohistochemistry, co-staining and Western blot analysis to evaluate the effects of LWDHD on renal fibrosis. Transforming growth factor beta-1 (TGF-β 1) was employed to stimulate endothelial-mesenchymal transition (EndMT) in EA.hy926 cells. The inhibitory effect of LWDHD on EndMT was validated through cellular morphology observations, Western blotting, and immunofluorescence assays.Results: LWDHD showed promise as a therapeutic agent by alleviating renal pathological injury and lowering collagen fiber accumulation. It enhanced Sirt1 expression while inhibiting the Wnt/β-catenin signaling pathway. Moreover, LWDHD increased the levels of the endothelial marker CD31 and decreased the expression of fibrosis-associated proteins, such as α-smooth muscle actin (α-SMA) and vimentin, thereby mitigating renal fibrosis.Conclusion: LWDHD has the potential to alleviate renal fibrosis, possibly through the upregulation of Sirt1, which inhibits the Wnt/β-catenin signaling pathway and thereby reduces EndMT.Keywords: renal fibrosis, LWDHD, network pharmacology, Sirt1, Wnt/β-catenin, EndMT |
