The phosphatidylinositol 3-kinase (PI3K)/Akt and RAS/RAF/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) pathways, mediate proliferation and survival in human lung cancer cells and share several downstream molecules, such as FOXO3a [1], caspase-9 [2], and Bad [3]. Here, AKT1 is linked to lung cancer.
