Features of the differentially expressed genes (DEGs) in the cancer-related WGCNA genes modules. a The Venn diagram indicating the overlapping genes between genes in the five cancer-related WGCNA modules and the common DEGs across the three datasets (TCGA, GSE44861, and GSE44076) identified by the MetaDE analysis (left), and the pie chart showing the number of overlapping genes in WGCNA modules (right). b The Gene Ontology biological processes (left) and Kyoto Encyclopedia of Genes and Genomes pathways (right) associated with the overlapping genes in the above figures. Horizontal axis represents gene number. The color and size of the dots indicate the p value. The closer the color is to red, the higher the significance
