Sinhyotaklisan as a Potential Therapeutic for Psoriasis: Network Pharmacology and Experimental Validation

Year: 2025

Abstract: , commonly used to treat skin disorders. This study aimed to investigate the therapeutic effects and underlying mechanisms of SHTLS in psoriasis through the network pharmacology analysis and experimental validation in vitro and in vivo. Bioactive compounds and molecular targets were identified using the Traditional Chinese Medicine Systems Pharmacology database, and key protein-protein interaction networks were analyzed via STRING and Cytoscape. In vitro, HaCaT cells were pretreated with SHTLS and stimulated with TNF-α, followed by assessments using proliferation assays, scratch assays, quantitative real-time PCR, and Western blotting. In vivo, the anti-psoriatic effects of SHTLS were evaluated in an imiquimod-induced psoriatic mouse model. A total of 36 key targets were significantly enriched in TNF-α, MAPK, HIF-1α, and IL-17 signaling pathways. SHTLS suppressed TNF-α-induced expression of VEGF and HIF-1α, while upregulating p53, thereby inhibiting keratinocyte hyperproliferation and angiogenesis. It also reduced IL-6 and IL-8 levels and blocked activation of the NF-κB and MAPK pathways. Histological analysis confirmed that SHTLS alleviated psoriatic lesions in vivo. These findings suggest that SHTLS may be a promising therapeutic candidate for psoriasis by targeting hyperproliferation, angiogenesis, and inflammation.
