Abstract:
Objective: To explore the possible mechanism for treating NRR in arrhythmia using
network pharmacology and molecular docking in this study.
Methods: Active compounds and targets for NRR were retrieved from the Traditional Chinese
Medicine Systems Pharmacology (TCMSP) Database and Analysis Platform, SymMap, and the
Encyclopedia of Traditional Chinese Medicine (ETCM) databases. Arrhythmia-related genes were
acquired from the Comparative Toxicogenomics Database (CTD) and the GeneCards database.
Overlapping targets of NRR associated with arrhythmia were acquired and displayed via a Venn
diagram. DAVID was applied for GO and KEGG pathway analyses. Cytoscape software and its
plug-in were used for PPI network construction, module division and hub nodes screening. Auto-
Dock Vina and qRT-PCR were carried out for validation.
Results: In total, 21 active compounds and 57 targets were obtained. Of these, coumarin was the predominant
category which contained 15 components and 31 targets. There were 5 key targets for NRR
in treating arrhythmia. These targets are involved in the apoptotic process, extrinsic apoptotic signaling
pathway in the absence of ligand, and endopeptidase activity involved in the apoptotic process by
cytochrome c. The main pathways were the p53 signaling pathway, Hepatitis B and apoptosis. The
molecular docking and qRT-PCR displayed good effects on hub node regulation in NRR treatment.
Conclusion: NRR plays an important role in anti-apoptotic mechanisms that modulate the p53 signaling
pathway, which may provide insight for future research and clinical applications focusing
on arrhythmia therapy.
