Common nodes of resistance to targeted therapies within the PI3K pathway. PI3K pathway alterations that confer resistance to targeted therapies across various tumor types are shown. CRC, colorectal cancer; EGFR, epidermal growth factor receptor; HER2, human epidermal growth factor receptor 2; HR, hormone receptor; INPP4B, inositol polyphosphate 4-phosphatase type II; MET, hepatocyte growth factor receptor; mTORC, mammalian target of rapamycin complex; PDK1, phosphoinositide-dependent kinase 1; PI3K, phosphoinositide 3-kinase; PIK3CA, phosphatidylinositol 3-kinase catalytic subunit alpha; PIK3CG, phosphatidylinositol 3-kinase catalytic subunit gamma; PIK3R2, phosphatidylinositol 3-kinase regulatory subunit beta; PIP2, phosphatidylinositol 4,5- bisphosphate; PIP3, phosphatidylinositol 3,4,5-trisphosphate; PTEN, phosphatase and tensin homolog; RTK, receptor tyrosine kinase.
