The KEGG results suggested that these genes were mainly enriched in the phosphatidylinositol3-kinase (PI3K)-protein kinase B (Akt) signaling pathway, cell cycle, cytokine–cytokine receptor interaction, proteoglycans in cancer, focal adhesion, protein digestion and absorption, motor proteins, the extracellular matrix (ECM)-receptor interaction, Hippo signaling pathway, and other pathways (Figure 6C,D). This evidence concerns the gene PIK3CA and cancer.
