GO enrichment analysis and PPI network analysis
A total of 916 DEGs mentioned above were analyzed by using the DAVID online tool. GO enrichment analyzed the result from biological processes, cell component and molecular function(Fig.3A). At the same time, the protein-protein interaction(PPI) network helped us systematically investigate the mechanism of the DEGs in the complete transcriptome of nasal polyp cells. A total of 916 DEGs were analyzed using the STRING online tool. 916 genes were introduced into PPI network, and then the PPI network was analyzed through MCODE in Cytoscape. Finally, a total of 2 core protein interaction networks were identified(Fig.3B).
