Figure 2. Identification, functional enrichment, and WGCNA analysis of DE-IRGs. (A, B) Heatmap of DEGs and DE-IRGs, respectively. (C, D) GO enrichment and KEGG analysis for DE-IRGs. (E) The scale-free fit index for soft-thresholding powers. Left: the relationship between the soft-threshold and scale-free R2. Right: the relationship between the soft-threshold and mean connectivity. (F) Dendrogram and module colors for DE-IRGs. (G) The correlations heatmap between modules and sample types.
