Figure 4. Gene Set Enrichment Analysis of HPDL. (A) The hallmarks gene set enrichment analysis (GSEA) of HPDL in pan-cancer. The size of the circle represents the false discovery rate (FDR) value of each cancer enrichment item, and the color represents the normalized enrichment score (NES) of each enrichment item. (B–I) HPDL’s GSEA results in TCGA pan-cancer. The most 20 related pathways of GSEA are presented in the form of a mountain map, and immune-related pathways are marked in red.
