Treatment and improvement of scar hyperplasia by panax notoginseng based on network pharmacology study on molecular mechanisms / 国际中医中药杂志

ABSTRACT

Objective We predicted the molecular mechanism of Panax notoginseng in the treatment and improvement of scar hyperplasia, by using the methods of network pharmacology and bioinformatics. Methods We collected of related active constituents and targets of Panax notoginseng by retrieving TCM systems pharmacology database and analysis platform (TCMSP), and collected of related active constituents and targets of scar by Genecards database and OMIM database. Cytoscape 3.6.1 software was used to construct"drugs-chemical components-targets-diseases" interaction network diagram. The protein in teraction network map (PPI) was constructed by STRING database. The key targets were used to analyze gene ontology (GO) enrichment and kyoto encyclopedia of genes and genome (KEGG) pathway enrichment. Results Totally 7 chemical compponents, including beta-sitosterol, quercetin, Stigmasterol and etc. and 108 targets, including AKT1, JUN, MAPK1, IL6 and ect. Panax notoginseng exerts its effects on scar mainly by acting on signal pathways, including PI3K-AKt signal pathway, MAPK signal pathway, TNF signal pathway and ect. Conclusions Based on the methodology of network pharmacology, this study preliminarily predicted the major targets and pathways Panax notoginseng in the treatment of scar, providing a direction for further studies.
