RAC‑α serine/threonine‑protein kinase (commonly referred to as AKT1)
It is known as the “survival kinase”. Akt mediates cell survival proliferation mainly by inhibiting the Bcl2 and MDM2 pathways, which otherwise promotes apoptosis.
Mechanisms of Akt1 in Cancer
Cell Survival: Akt1 promotes cell survival by inhibiting apoptotic pathways, allowing cancer cells to evade programmed cell death.
Cell Proliferation: It enhances cell cycle progression and proliferation through various signaling pathways.
Metabolism: Akt1 regulates glucose metabolism and lipid synthesis, supporting the metabolic demands of rapidly dividing cancer cells.
Angiogenesis: It promotes the formation of new blood vessels, facilitating tumor growth and metastasis.
Akt1 is frequently activated, with its expression levels often correlating with prognosis across various cancer types.
