PI3K Akt mTOR

Meaning

PI3K/Akt/mTOR refers to a critical intracellular signaling cascade, the Phosphoinositide 3-kinase (PI3K) / Akt (Protein Kinase B) / mammalian Target of Rapamycin (mTOR) pathway, which acts as a master regulator of cell growth, proliferation, survival, and metabolism. This pathway is a key sensor of nutrient and energy status, linking hormonal signals, particularly from insulin and growth factors, to cellular anabolic processes. Its dysregulation is implicated in both aging and numerous pathologies, including cancer and metabolic syndrome.
