Identification of Potential Key Genes and Prognostic Biomarkers of Lung Cancer Based on Bioinformatics

Figure 2

The common differentially expressed gene (DEG) protein–protein interaction network was constructed through a retrieval tool to retrieve the interacting genes and the core genes identified by the molecular complex detection (MCODE) application in Cytoscape. The orange circle indicates DEG upregulation, and the green circle indicates DEG downregulation: (a) shows 81 upregulated and 221 downregulated genes in the protein–protein interaction network, and (b) shows the core genes analyzed by MCODE analysis using Cytoscape software.
