Abstract:
ObjectiveTo explore the underlying molecular mechanism of Xiaochuanning granules in the treatment of bronchial asthma based on the network pharmacology and experimental verification through the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway on ovalbumin （OVA） sensitization-induced bronchial asthma model in rats. MethodThe main active ingredients and targets of Xiaochuanning Granules were screened out from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine （BATMAN-TCM）. The targets related to bronchial asthma were obtained from five disease databases such as GeneCards and Online Mendelian Inheritance in Man （OMIM）. The common targets were screened out through the Venn diagram. STRING was used to construct the protein-protein interaction （PPI） network of "compound-disease"， and Cytoscape 3.8.0 was used to establish a network of key active ingredients of Xiaochuanning granules and core target genes （"ingredient-gene" network）. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses were performed through DAVID. The bronchial asthma model was induced by OVA stimulation in rats. Bronchial and lung tissue inflammation was observed by hematoxylin-eosin （HE） staining， and the enrichment analysis results of the network pharmacology were verified by Western blot. ResultIn this experiment， 232 active ingredients and 4 687 related targets of Xiaochuanning granules were screened out， and 233 common targets of Xiaochuanning granules and bronchial asthma were collected， including eosinophil-derived neurotoxin 1 （EDN1）， cyclic AMP response element-binding protein 1 （CREB1）， cyclin-dependent kinase inhibitor 1A （CDKN1A）， epidermal growth factor receptor （EGFR）， mitogen-activated protein kinase 14 （MAPK14）， and Akt1. KEGG pathway analysis revealed 186 related signaling pathways， indicating that the PI3K/Akt signaling pathway presumedly played a key role in the treatment of bronchial asthma by Xiaochuanning granules. The animal experiment showed that Xiaochuanning granules relieved the airway inflammation and smooth muscle hyperplasia in rats and down-regulated the gene expression of PI3K and Akt as compared with the conditions in the model group （P<0.05）. ConclusionXiaochuanning granules have the characteristics of multi-component， multi-target， and multi-pathway synergistic effect in the treatment of asthma. Xiaochuanning granules may exert anti-inflammatory effects by regulating the expression of genes related to the PI3K/Akt signaling pathway. The present study is expected to provide a theoretical basis for follow-up in-depth research on the complex mechanism of Xiaochuanning granules in the treatment of bronchial asthma.
