Identification of the potential mechanisms of Huzhang Tongfeng Granules against acute gouty arthritis through network pharmacology and in vivo analysis

Objective: To identify the potential mechanism of Huzhang Tongfeng Granules (HTG) for the treatment of acute gouty arthritis (AGA). Methods: First of all, we used network pharmacology to build a network of components-targets of HTG. Secondly, the ClusterONE algorithm was applied to construct a modular network as well as discover hub genes and kernel pathways. Lastly, the MSU crystals-induced AGA mice model was used to verify the hub genes and kernel pathways of HTG. Results: HTG down-regulated the expressions of ADRB3, PIK3CA, FYN, PIK3R1, CASR, PLCG1, SYK, EGFR, and up-regulated MC1R, MC5R. Moreover, according to the kernel clusters enrichment analysis, HTG down-regulated NF-κB and P13K-Akt signaling pathways to ameliorate the AGA mice model. Conclusion: In summary, the potential targets and kernel pathways were proved in this study, supporting the clinical application of HTG for the treatment of AGA.
