摘要
OBJECTIVE:To explore the underlying molecular mechanism of Phellinus linteus(P.linteus).METHODS:We used a tandem mass tag-based quantitative proteomic method to determine the differentially expressed proteins.Network pharmacology analysis was used to analysis the main components of P.linteus and construct the compound-target network.Western blotting and quantitative real-time polymerase chain reaction(qRT-PCR)were used to validate the analyses results.RESULTS:The expression levels of thrombospondin-1(TSP-1)and transforming growth factor(TGF)-β1/Smad3 signaling pathway proteins were significantly upregulated in focal segmental glomeruloscleosis(FSGS)rats.The P.linteus reduced the expression levels of TSP-1 and TGF-β1 signaling pathway proteins.Network pharmacology analysis revealed that protocatechualdehyde was the main active component.Subsequent in vivo and in vitro experiments validated the results of proteomic and network pharmacology analyses.CONCLUSIONS:Our results suggested that P.linteus may inhibit renal sclerosis by inhibiting TSP-1-activated TGF-β1 signaling and may have potential applications in the treatment of FSGS.
