Mechanism of YuPingFeng in the Treatment of COPD Based on Network Pharmacology

Abstract EN

YuPingFeng (YPF) granules are a classic herbal formula extensively used in clinical practice in China for the treatment of COPD.

However, the pathological mechanisms of YPF in COPD remain undefined.

In the present research, a network pharmacology-based strategy was implemented to elucidate the underlying multicomponent, multitarget, and multipathway modes of action of YPF against COPD.

First, we identified putative YPF targets based on TCMSP databases and constructed a network containing interactions between putative YPF targets and known therapeutic targets of COPD.

Next, two topological parameters, “degree” and “closeness,” were calculated to identify target genes in the network.

The major hubs were imported to the MetaCore database for pathway enrichment analysis.

In total, 23 YPF active ingredients and 83 target genes associated with COPD were identified.

Through protein interaction network analysis, 26 genes were identified as major hubs due to their topological importance.

GO and KEGG enrichment analysis results revealed YPF to be mainly associated with the response to glucocorticoids and steroid hormones, with apoptotic and HIF-1 signalling pathways being dominant and correlative pathways.

The promising utility of YPF in the treatment of COPD has been demonstrated by a network pharmacology approach.
