ETHNOPHARMACOLOGICAL RELEVANCE: Lamiophlomis rotata (Benth.)Kudo (L. rotata), known in China as Duyiwei (DYW), is a well-known traditional Tibetan medicine. Its earliest documented use appears in the classic Tibetan medical text The Four Medical Tantras (rGyud bzhi). Traditionally, DYW has been widely applied to treat pain, inflammation, and bleeding disorders. However, its pharmacological mechanisms, particularly in the treatment of acne, remain poorly understood.
AIM OF THE STUDY: To investigate the potential anti-acne mechanisms of DYW using network pharmacology, along with in vitro and in vivo experimental validation, to provide scientific evidence supporting its traditional use.
MATERIALS AND METHODS: Network pharmacology was employed to predict the potential anti-acne targets of DYW. Then, we investigated the effects of DYW on inflammatory response, antioxidants and skin barrier protection, and validated the main pathways predicted by network pharmacology in cellular studies. In vivo study, DYW extract was applied topically to Propionibacterium acnes(P.acnes) induced acne mice, and its therapeutic effects were evaluated biologically and morphologically.
RESULTS: DYW extract significantly upregulated AQP3 and other skin barrier-related genes in HaCaT cells, and inhibited inflammatory cell migration. It demonstrated antioxidant activity by reducing intracellular ROS levels and scavenging DPPH and ABTS radicals. Furthermore, DYW extract downregulated key inflammatory cytokines, including TNF-α, IL-6, and IL-1β. Molecular analysis revealed that its therapeutic effects may be partially mediated through the EGFR/PI3K/AKT1 signaling pathway.
CONCLUSION: The results indicate that DYW extract ameliorates acne, and this effect is mediated, at least in part, through the inhibition of the EGFR/PI3K/AKT1 signaling pathway.
