As shown in Figure 5C, GSEA between the high- and low-risk groups suggested that the high-risk group was enriched in ErbB signaling pathway, MAPK signaling pathway, mTOR signaling pathway, pathways in cancers, and WNT signaling pathway, and the low-risk group was enriched in apoptosis, B-cell receptor signaling pathway, natural killer cell-mediated cytotoxicity, oxidative phosphorylation, peroxisome, and T-cell receptor signaling pathway. Here, MTOR is linked to cancer.
