As shown in the bubble chart, KEGG pathway analysis revealed that FCRGs were primarily enriched in the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, human papillomavirus (HPV) infection, focal adhesion, cytoskeleton in muscle cells, phagosome, proteoglycans in cancer, platinum drug resistance, ECM–receptor interaction, glutathione (GSH) metabolism, and type 1 diabetes. Here, AKT1 is linked to cancer.
