特发性非肝硬化门静脉高压症的关键基因通路筛选与潜在中药预测OA

Objective To with analyzing the gene expression profile of idiopathic non-cirrhotic portal hypertension(INCPH)by bioinformatics methods,we may obtain its key genes and signaling pathways to explore the molecular mechanism of INCPH and predict the potential traditional Chinese medicine.Methods The gene microarray dataset GSE77627 on INCPH was downloaded from gene expression omnibus(GEO)database,the data were normalized and screened for differential genes(DEGs)of INCPH using R language,and all DEGs were analyzed for gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)enrichment using Metascape database,and protein-protein interaction network was constructed by STRING database;meanwhile DEGs with the top 15 Degree values were screened as key genes using CytoHubba plugin.Subsequently,the key genes were mapped to each other with the medical ontology information retrieval platform(coremine medical)to screen potential Chinese herbal medicines for the treatment of INCPH with P<0.05,and the potent components that potential Chinese medicines have were screened from the TCMSP database,imported into Cytoscape software to construct a Chinese medicine correlation network map and predict the key targets.Results A total of 1880 DEGs were screened,including 1061 up-regulated and 819 down-regulated genes.DEGs were analyzed using the protein interaction database STRING and cytoHubba in Cytoscape software to obtain key genes,which were RPS27A,CDC42,EIF4E,MAPK1,PIK3R1,RPS6,RPS9,RPS8,RPL15,RPL27A,RPL24,RPL27,RPL26,RPL12 and MAPK14.The GO and KEGG analysis mainly involved gamete production and AGE-RAGE signaling pathway in INCPH.Conclusion The potential traditional Chinese medicines screened for INCPH are Ginseng Radix et Rhizoma,Salviae Miltiorrhizae Radix et Rhizoma,Scutellariae Radix,etc,which may be a potential source of molecular drugs for the treatment of INCPH.
