Network pharmacologic study on the treatment of hepatocellular carcinoma by Hedyotis diffusa
Objective To explore the possible mechanism of the anticancer effect of Hedyotis diffusa on HCC by using molecular docking technology and network pharmacology.Methods Literature research and TCMSP database were used to obtain the functional monomer components of Hedyotis diffusa,and the targets gene of functional monomer components were predicted by TCMSP.DisGeNET,GeneCards,OMIM and TTD databases were used to obtain the targets gene of HCC.Intersection target gene of Hedyotis diffusa and HCC were obtained to make the Venn diagram.GO functional enrichment analysis and KEGG pathway enrichment analysis were performed by DAVID.Cytoscape 3.9.1 software was used to make the network of the functional monomer components role of Hedyotis diffusa targeted disease pathways.The STRING database was used to establish a PPI network between the proteins of the intersection target genes,and Cytoscape's CytoNCA plug-in was used to screen for core targets genes,and the GEPIA2 database was used to evaluate the relationship between core targets gene expression and HCC prognosis.Molecular docking was performed by using the Discovery Studio software.Results A total of 56 intersection target genes were obtained.GO functional enrichment analysis showed that these genes negatively reg-ulated apoptosis and positively regulated RNA polymerase Ⅱ promoter transcription,while KEGG pathway enrichment analysis showed that these genes were mainly involved in a variety of pathways,such as TNF,IL-17,PI3K-Akt and JAK-STAT signaling pathways.16 core target genes were selected from 56 intersection target genes,among which MMP 9,VEGFA and EGF showed high expression associated with poor prognosis in HCC and high ESR1 expression with good prognosis of HCC.Molecular docking results demonstrated a good binding of MMP 9 and VEGFA to quercetin.Conclusion We predict the molecular mechanisms and signaling pathways of the functional genes associated with the treatment of HCC of Hedyotis diffusa.It can provide a scientific basis for the effective functional monomer components extracted from Hedyotis diffusa for the treatment of HCC in the future.
