Potential mechanism of Ginseng Radix et Rhizoma for treatment of Alzheimer's disease by regulating ferroptosis based on network pharmacology

Objective The possible target and mechanism of Ginseng Radix et Rhizoma against Alzheimer''s disease were investigated by network pharmacology method. Methods The active ingredients of Ginseng Radix et Rhizoma and their corresponding targets were obtained by using TCMSP database. Therapeutic targets for Alzheimer''s disease were obtained from GeneCards database. The co-action targets of Ginseng Radix et Rhizoma active ingredients and Alzheimer''s disease were obtained using Venn online tool. Cytoscape software was used to construct the network diagram of interaction between Ginseng Radix et Rhizoma, active ingredient and target, and CytoHubba plug-in was used to obtain the core target and core subnetwork. DAVID database was used for gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. FerrDb database was searched to obtain and analyze the genes regulating ferroptosis. Finally, the data of Ginseng Radix et Rhizoma active ingredients, Alzheimer''s disease and ferroptosis were comprehensively analyzed and predicted. Results Sixteen active components were screened from Ginseng Radix et Rhizoma, and seven possible targets of Ginseng Radix et Rhizoma regulating ferroptosis and anti-Alzheimer''s disease were predicted, including HMOX1, NOS2, PTGS2, IFNG, MAPK8, JUN, and RELA. Ferroptosis pathway is regulated by mediating HIF-1, TNF, T cell receptor, Toll-like receptor, neurotrophic factor, cAMP, MAPK, NOD-like receptor, and other signaling pathways, thus combating the occurrence and progression of Alzheimer''s disease. Conclusion The multi-component, multi-target and multi-pathway action characteristics of Ginseng Radix et Rhizoma against Alzheimer''s disease were explored by using network pharmacology, and the possible targets and signal transduction mechanism of Ginseng Radix et Rhizoma active ingredients regulating ferroptosis against Alzheimer''s disease were explored.
