Potential therapeutic targets and biological mechanisms of Centella asiatica on hepatic fibrosis. - GreenMedInfo Summary

Background: Liver fibrosis is a common result of the repair process of various chronic liver diseases. This study is a network pharmacology study on the potential therapeutic targets and biological mechanisms of Centella asiatica for liver fibrosis.

Methods: The chemical components and potential targets of Centella asiatica were screened through TCMSP, PubChem database, and Swiss Target Prediction database. The DisGeNET and GeneCards databases were used to obtain targets of HF. Venn diagrams were used to find key targets, and draw protein interaction maps. Cytoscape software was used to construct an interaction network map of drug-component-target-disease-pathway. The mechanisms of action were predicted through enrichment analysis and KEGG analysis.

Results: In total, 6 main components, 297 drug targets, 337 HF targets, and 48 drug-disease targets were obtained in Centella asiatica. The key targets involved IL6, TNF, VEGFA, TP53, IL1β, MMP9, CXCL8, EGFR, JUN, SRC, MMP2, and TGF-β, among others. A total of 1293 entries were obtained by Gene Ontology (GO) enrichment analysis, which mainly involved the regulation of reactive oxygen species metabolic process, the regulation of smooth muscle cells, and the regulation of DNA-binding transcription factor activity. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment mainly screened 191 pathways, including the MAPK signaling pathway, the relaxin signaling pathway, and the Toll-like receptor signaling pathway, among others.

Conclusions: Centella asiatica may have a therapeutic effect on HF through multiple targets and pathways. Its mechanism is mainly related to the MAPK signaling pathway and the relaxin signaling pathway.
