Based on network pharmacology,molecular docking,and experimental validation,this study explored the mechanisms of Geranium wilfordii Maxim(GWM)in the treatment of liver injury.Mice were randomly divided into a control group(CON group),a model group(CCl4 group),a high-dose drug group(GWM-H group),and a low-dose group(GWM-L group).The liv-er injury model in mice was induced by CCl4,and liver tissue pathological morphology was ob-served,along with the measurement of the relative gene expression levels of liver inflammatory factors.Active ingredients of traditional Chinese medicine and target information of Chinese medi-cine and diseases were obtained through databases such as TCMSP,PubChem,Swiss Target Pre-diction,Super-PRED,Gene Cards,and DisGeNET.Intersecting the targets of liver injury,necropto-sis,and drugs yielded potential drug targets.String database was used for protein-protein interac-tion(PPI)analysis of the potential targets.Furthermore,Cytoscape was utilized to construct a net-work diagram of"drug-disease-active ingredient-intersection target,"Wei Sheng Xin was used for GO and KEGG pathway analysis.Molecular docking was performed using MOE software,and the results of molecular docking were experimentally validated to detect the expression of key targets in the RIPK1/RIPK3/MLKL signaling pathway.Animal experiments showed that compared to the CON group,the CCl4 group of mice exhibited a significant increase in liver organ index(P＜0.05),markedly elevated serum AST activity(P＜0.05),and a highly significant increase in ALT activity(P＜0.01).Pathological examination revealed chaotic liver lobules,severe hepatocyte steatosis,ex-tensive hepatocyte necrosis,and inflammatory cell infiltration in the livers of mice in the CCl4 group.In comparison to the CCl4 group,the GWM-H group showed a significant decrease in liver organ index(P＜0.05),while the GWM-L group displayed a downward trend.The GWM-H group exhibited a significant reduction in serum AST activity(P＜0.05),the GWM-L group showed a decreasing trend in serum AST activity,the GWM-H group demonstrated a highly significant de-crease in serum ALT activity(P＜0.01),and the GWM-L group displayed a significant decrease in serum ALT activity(P＜0.05).Histopathological examination revealed that the drug treatment groups could improve CCl4-induced liver injury,with the GWM-H group showing better efficacy than the GWM-L group.RT-qPCR results of liver tissues showed that compared to the CON group,the CCl4 group exhibited a highly significant increase in the relative expression of IL-1βand PGE2 mRNA(P＜0.01),while the mRNA relative expression of COX2 showed an increasing trend.In contrast,compared to the CCl4 group,the GWM-H group showed a remarkably significant decrease in the relative expression of IL-1βmRNA(P＜0.01),a significant decrease in PGE2 mR-NA expression(P＜0.05),and a decreasing trend in COX2 mRNA expression.Through network pharmacology,56 potential targets related to GWM in ameliorating necroptosis-induced liver injury were identified.Key targets,based on degree value,include TNF,Bcl2,HSP90AA1,and Caspase8,while the key components are quercetin,luteolin,kaempferol,and ellagic acid.Functional enrich-ment analysis yielded 2 173 entries for GO and 146 biological pathways for KEGG.Molecular doc-king results indicated a strong binding capacity between the main components of GWM and key targets.RT-qPCR experimental results showed that compared to the CON group,the CCl4 group exhibited a extremely significantly increase in the mRNA relative expression of TNF-α,TNFR1,MLKL(P＜0.01),significantly increase in the mRNA relative expression of FAS,RIPK1,RIPK3 mRNA(P＜0.05),and a significant decrease in Caspase 8 mRNA expression(P＜0.05).The addi-tion of GWM successfully reversed this trend;compared to the CCl4 group,the GWM-H group showed a highly significant decrease in the mRNA relative expression of TNF-α,TNFR1,FAS and MLKL mRNA(P＜0.01),significant decrease in RIPK1,RIPK3 mRNA expression(P＜0.05),and an increasing trend in CASPASE8 mRNA expression.GWM exerts hepatoprotective effects through multiple components and pathways,among which inhibition of the RIPK1/RIPK3/MLKL pathway reduces hepatocyte necroptosis,potentially serving as one of the essential mechanisms for its protective effects.

Based on network pharmacology,molecular docking,and experimental validation,this study explored the mechanism by which Hypericum japonicum Thunb-Prunella vulgaris treat liver injury.Mice were randomly divided into four groups:a control group(CON),a model group(CCl4),a high-dose drug group(TXD-H),and a low-dose drug group(TXD-L).A mouse liver in-jury model was established using CCl4 induction.The pathological morphology of liver tissue was observed,and the serum levels of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)were measured.Active ingredients of traditional Chinese medicine and targets related to these medicines and diseases were obtained from databases such as TCMSP,PubChem,Swiss Tar-get Prediction,GeneCards,and DisGeNET.The intersection of these targets was used to identify potential drug targets.A network diagram illustrating the relationships between"drug-active com-ponent-intersection target"was constructed using Cytoscape.Potential targets were analyzed using the STRING database for protein-protein interaction(PPI)analysis and the DAVID database for Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis.Molecular docking validation was performed using AutoDock Tools software.Subsequently,key target genes,including those related to the NLRP3 inflammasome and pyroptosis,were detected to validate the molecular docking results.Animal experimental results showed that compared to the CON group,serum AST and ALT activities in the CCl4 group mice were significantly increased(P＜0.01),while in the TXD-L group,serum AST and ALT activities were significantly decreased(P＜0.05)compared to the CCl4 group,and in the TXD-H group,AST and ALT activities were significantly decreased(P＜0.01).Through network pharmacology,135 potential targets were i-dentified,with key components found to be tetramethoxyluteolin,quercetin,kaempferol,luteolin and morin based on degree values,and key targets including TNF,SRC,AKT1,EGFR and ESR1.GO enrichment analysis yielded 304 entries,while KEGG enrichment analysis identified 91 biologi-cal pathways.Molecular docking results demonstrated strong binding between the main compo-nents of Hypericum japonicurn Thunb-Prunella vulgaris and key targets.qPCR results showed that compared to the CON group,the CCl4 group exhibited upregulated relative expression levels of SRC,EGFR,TNF-α,AKT1,and IL-18 mRNA,with significant increases in MyD88,NF-κB,IL-1β,NLRP3,Caspase-1,and ASC mRNA(P＜0.05),and significant upregulation of TLR4 and GS-DMD mRNA(P＜0.01).Compared to the CCl4 group,the TXD-H group displayed significant downregulation of EGFR,AKT1,TLR4,IL-1β,and GSDMD mRNA(P＜0.01),significant decrea-ses in TNF-α,MyD88,NF-κB,NLRP3,and ASC mRNA(P＜0.05),while SRC,IL-18,and Caspase-1 mRNA showed a downward trend.In conclusion,Hypericum japonicum Thunb-Prunel-la vulgaris exerts hepatoprotective effects through multiple components and pathways,among which inhibition of the NF-κB-NLRP3 pathway to reduce hepatocyte pyroptosis may be one of the important pathways for its protective effects.
