Abstract

This study aimed to investigate the mechanism of Xuanhong Dingchuan Tang (XHDCT) in delaying bronchial asthma inflammation via the microRNA (miR)-107-3p/prostaglandin endoperoxide synthase 2 (PTGS2)/mitogen-activated protein kinase (MAPK) axis. Based on the network pharmacological analysis, XHDCT chemical constituents and targets of each chemical constituent were screened through the TCMSP database, and differential-expressed genes of bronchial asthma were obtained from the GEO database, which were intersected to get XHDCT potential anti-inflammatory targets. The key anti-inflammatory targets of XHDCT were acquired by protein-protein interaction (PPI) analysis of the candidate targets. Bronchial asthma mouse models were established and the pathological changes of lung tissues were observed. Serum IgE levels were tested. Total cells and eosinophils in bronchoalveolar lavage fluid (BALF) were counted. The expression of Th2-associated cytokines (interleukin (IL)-4, IL-5, and IL-13) and chemokines (monocyte chemoattractant protein-1 (MCP-1) and eotaxin) in BALF were measured. The targeting relationship between miR-107-3p and PTGS2 was tested. XHDCT delayed bronchial asthma inflammation in in-vivo asthma mouse models. A total of 155 active ingredients and their 341 targets were intersected with bronchial asthma-relevant genes, obtaining 20 potential targets of XHDCT for bronchial asthma treatment. Based on the PPI and “drug-component-target” network diagram, PTGS2 was found to be in a central position. PTGS2 was downregulated and miR-107-3p was upregulated in bronchial asthma mice after XHDCT treatment. PTGS2 overexpression activated the MAPK signaling pathway to promote inflammation in bronchial asthma mice, whereas inflammatory symptoms were reduced and the MAPK signaling pathway was inhibited after XHDCT treatment. miR-107-3p was an upstream regulatory miRNA for PTGS2. After miR-107-3p interference, the activation of the PTGS2/MAPK axis promoted inflammation in bronchial asthma mice, whereas the inflammatory symptoms were reduced after XHDCT treatment. XHDCT promotes anti-inflammatory effects in bronchial asthma via the miR-107-3p/PTGS2/MAPK axis.

期刊介绍: Functional & Integrative Genomics is devoted to large-scale studies of genomes and their functions, including systems analyses of biological processes. The journal will provide the research community an integrated platform where researchers can share, review and discuss their findings on important biological questions that will ultimately enable us to answer the fundamental question: How do genomes work?
