The PI3K/Akt/mTOR signaling pathway is a critical cellular signaling pathway that regulates various cellular processes, including growth, proliferation, survival, and metabolism.
In some cancers, there is an overexpression of PI3K, which can enhance signaling through the pathway even in the absence of growth factor stimulation.
Increased expression of Akt isoforms (Akt1, Akt2, and Akt3) has been observed in several cancers.
Both mTORC1 and mTORC2 can be overexpressed in tumors.
