PIK3CA and cancer: The GO function enrichment analysis results revealed that relevant targets were primarily enriched in BPs such as signal transduction, apoptotic processes, and inflammatory responses (Fig. 5D); CCs like nuclei, cytoplasm, and plasma membranes (Fig. 5E); MFs including ATP binding, protein kinase activity, and DNA binding (Fig. 5F); as well as signaling pathways like cancer pathways, PI3K-AKT signaling pathways, and MAPK signaling pathways (Fig. 5G).
