Target genes of genistein against osteosarcoma screened based on bioinformatics

Genistein is a kind of natural small molecular substance,which has shown anti-tumor effect in a variety of tumors.This paper explores the genes of genistein against osteosarcoma through bioinformatics analysis.Target genes associated with genistein were downloaded from DrugBank and imported to string database for analysis.With PPI network diagram created by Cytoscape,the plugin Cytohubb was applied to analyze the PPI network and 25 hub genes were acquired.WebGestalt was adopted to analyze KEGG pathways of 25 genes,and the target genes of the pathways associated with osteosarcoma were selected.The obtained target genes were verified using HCMDB.The miRNA of the genes were predicted by miRDB and verified in GSE65071 database.A total of 13 target genes associated with genistein were selected,and 11 genes whose pharmacological activities were not clear were chosen for subsequent analysis.From the string database,284 genes related to 11 target genes were obtained,and 25 hub genes were analyzed using WebGestalt.Subsequently,the target genes of NF-kappa B and Rap1 signaling pathways were selected and verified in the HCMDB database.Lastly,miRDB and GSE65071 databases to acquire hsa-miR-23b-3p,hsa-miR-23a-3p,hsa-miR-141-3p,and hsa-miR-200a-3p.The study showed that CXCL8,CXCL12,LPAR1,and CNR1,as well as hsa-miR-23b-3p,hsa-miR-23a-3p,hsa-miR-141-3p,and hsa-miR-200a-3p might be the therapeutic target genes for osteosarcoma.
