CD274 and neoplasm: KEGG pathways (Figure 5B) were enriched in several classical tumor signaling pathways, including the Wnt signaling pathway, PI3K Akt signaling pathway, mTOR signaling pathway, etc. In addition, we found that the immune-related signaling pathways included the B-cell and T-cell receptor signaling pathways, Th17 differentiation, and the PDL1 and PDK1 checkpoint signaling pathways.
