Dysregulation of the PI3K/Akt/mTOR pathway is frequently found in solid tumors and results in increased tumor cell growth, survival, and resistance to chemotherapy and radiotherapy.

(PI3K Alpha/Beta Inhibitor BAY1082439, NCI Thesaurus)

Dysregulation of the PI3K/Akt/mTOR pathway is frequently found in solid tumors and results in the promotion of tumor cell growth, survival, and resistance to both chemotherapy and radiotherapy.

(PI3K-beta Inhibitor GSK2636771, NCI Thesaurus)

Activation of the PI3K/mTOR pathway promotes cell growth, survival, and resistance to chemotherapy and radiotherapy. mTOR is a serine/threonine kinase downstream of PI3K, which also has PI3K-independent activity.
