Objective:To obtain the relevant information of pathway and gene by using the database of DAVID,analyze the function and distribution of important genes,screen out the target genes related to Ulcerative Colitis and promote the study of the pathogenesis of UC and the development of new drugs.Methods:The Ulcerative Colitis was used to search UC related genes in TTD,Drugbank,DisGeNET database.The obtained gene data was input to the database of Daved,and the data of gene enriched pathway was obtained 87 genes were Significant enriched in the first 20 KEGG pathways.The 87 genes were input to the string database to make the interaction network diagram,and the key genes enriched in the pathway were also made the network diagram,and the two network diagrams were compared.Results:RELA,TNF,IL1B,NFKB1,IL6 and IL10 were among the highest ranked genes in two network diagrams.Conclusion:The study of RELA,TNF,IL1B,NFKB1,IL6 and IL10 is necessary for us to study further.The pathogenesis of UC was associated with multiple pathways such as NF-kappa B signaling pathway,Jak-STAT signaling pathway,TNF signaling pathway and so on.It is helpful to understand the pathogenesis of disease and provide a reliable target for the development of new drugs by analyzing the pathway and the network diagram of the interaction between genes and disease related genes.
