基于生物信息学和细胞实验验证探讨甘草干姜汤治疗哮喘的作用机制
Effects of Gancao Ganjiang Decoction(甘草干姜汤)on Asthma Based on Bioinformatics and Cellular Experimental Verification
摘要
Abstract
Objective:To investigate the potential mechanisms of Gancao Ganjiang decoction in alleviating asthma symptoms by network pharmacology and molecular docking.Methods:Firstly,the active ingredients and action targets of Gancao Ganjiang decoction were collected through TCMSP database and Swiss Target Prediction.The related targets were searched with the help of GeneCards and OMIM databases with asthma as the keyword,and the results were intersected with the active ingredient targets.The intersection targets are taken as the potential targets for treating asthma.Secondly,the protein-protein interaction network analysis is carried out on the potential targets to acquire the key targets of Gancao Ganjiang decoction in the treatment of asthma.The enrichment analysis results of GO and KEGG pathways were obtained by using the DAVID database.Molecular docking simulation of the active ingredients and protein receptors of Gancao Ganjiang decoction were carried out with the help of Autodock Vina software.Quantitative Real-time PCR and ELISA experiments verified the core targets and potential mechanisms of Gancao Ganjiang decoction in the treatment of asthma from the mRNA and protein levels,respectively.Results:A total of 97 active ingredients of Gancao Ganjiang decoction,3 223 asthma targets,216 drug targets,and 141 potential targets of Gancao Ganjiang decoction in treating asthma were screened out through network pharmacology analysis.GO and KEGG enrichment results showed that the treatment mechanisms of drug were related to biological processes and pathways about inflammation and immunity.Molecular docking verified that the affinity energy of molecule ligands and receptors of Gancao Ganjiang decoction was less than or equal to-5 kcal/mol,and the binding force was stable.The PCR results showed that Gancao Ganjiang decoction could reduce IL-6 mRNA,IL-1 β mRNA and TNF-α mRNA relative expression levels,as well as the core targets RELA mRNA,PTGS2 mRNA and MAP1 mRNA(P＜0.05).ELISA results showed that Gancao Ganjiang decoction could reduce the relative expression level of inflammatory factor IL-6 protein.Conclusion:Gancao Ganjiang decoction may relieve asthma by inhibiting airway inflammation and regulating the expression of key targets in MAPK and NF-κB signaling pathways.关键词
