The KEGG enrichment analysis found that the main mechanisms of ginseng against AD were neuroactive ligand-receptor interaction, serotonergic synapse, calcium signaling pathway, cAMP signaling pathway, FoxO signaling pathway, Ras signaling pathway, PI3K-AKT signaling pathway, and Rap1 signaling pathway. The gene discussed is AKT1; the disease is Alzheimer disease.
