Résumé
Aim To investigate anrl further verify the anti-PD activity and underlying mechanism of Eucom¬mia ulmoides and based on network pharmacological methods and zebrafish Parkinson's disease ( PD) mod¬el.Methods The DISGENET database and TCMSP database were used to screen the active components, key targets of Eucommia ulmoides and PD related tar¬gets.The network diagram of active components-tar- gets-PD was drawn.The protein interaction network di¬agram was constnicted.GO enrichment analysis and KEGG pathway enrichment analysis were performed.Hie behavioral detection was verified by and quantita¬tive real-time PCR (qRT-PCR) based on zebrafish PD model.Results The network pharmacological study screened the potential targets associated with anti-PD action of Eucommia ulmoides.Protein-protein interac¬tion network ( PPI) analysis showed that there was tight interaction among thees targets.GO and KEGG enrichment analysis showed that Eucommia ulmoides could regulate the levels of PD neurotransmitter and the activity of dopamine neurotransmitter receptor, in¬volved in dopaminergic synapses and other related sig¬naling pathways.In vivo zebrafish PD model experi¬ments confirmed the anti-PD activity of Eucommia ul¬moides, which was related to the regulation of dopam¬inergic nervous system.Conclusions The anti-PD activity, active components, and potential targets of Eucommia ulmoides are revealed in this study.In vivo experiments verified that Eucommia ulmoides can alle¬viate PD-like symptoms in zebrafish, and it also reveals that Eucommia ulmoides exert anti-PD activity by regu¬lating dopaminergic nervous system.
