Study on mechanism for treating ischemic stroke of Siegesbeckiae Herba based on network pharmacology / 中国中药杂志

Xixiancao( Siegesbeckiae Herba) has the effect of treating ischemic stroke( IS),however,the mechanism has not been fully elucidated. In this study,combined with Lipinski's five principles and Veber oral bioavailability rules,68 chemical components of Xixiancao were obtained by database and literature search. Based on the reverse targeting,248 potential targets were obtained and mapped it to the ischemic stroke target set,47 potential targets for the treatment of ischemic stroke were obtained. Molecular docking technique was used to verify that the Xixiancao component has good binding activity to potential targets. GO enrichment analysis and pathway analysis were performed on potential targets using Clue GO. GO enrichment analysis showed that Xixiancao was mainly involved in life processes such as neuronal apoptosis,cholesterol storage and blood pressure regulation. Pathway analysis showed that Xixiancao may promote vascular repairing and regeneration by regulating the expression of ADAMTS1,FLT1 and KDR in VEGFA-VEGFR2 signaling pathway,activate cell survival signals and inhibit neuronal apoptosis by regulating the expression of CAMK2 AA,MDM2,MAPK1,MAPK3,CDK5 and MAPK10 in brain-derived neurotrophic factor signaling pathway and PI3 K-Akt signaling pathway. Lipid homeostasis and inflammation may also be regulated by Xixiancao through regulating the expression of ESR1,NR1 H3,PPARA,PPARG in the nuclear receptor signaling pathway. In addition,Xixiancao could also prevent platelet aggregation by regulating the expression of ITGA2 B,F2,F10,and ALB,and play an antithrombotic role. The results of this study indicate that Xixiancao plays an important role in the treatment of ischemic stroke mainly through anti-thrombosis,promoting angiogenesis,protecting neurons,anti-inflammatory and regulating blood pressure and lipids.
