The PI3K Pathway in Cancer

The phosphoinositol 3 kinase (PI3K) pathway has been demonstrated to regulate many cellular processes, and when hyperactivated, to promote cancer. Learn more about the role of PI3K signaling in promoting the survival and proliferation of tumors.1-4


Acronyms: AKT = Ak strain transforming; mTOR = mammalian target of rapamycin; PI3K = phosphatidylinositol-3-kinase; PIP3 = phosphatidylinositol (3,4,5)-trisphosphate; RTK = receptor tyrosine kinase.
