AKT1 and acute lymphoblastic leukemia: Albeit in our series it was not possible to verify a conclusive statistical higher expression of p‐Akt in cell lines when compared to T‐lymphocyte controls possibly because of the small sample number, our results show that the PI3K/Akt pathway is also active in ALL, although at a lower frequency (35%), in both T‐ (30%) and in B‐ALL (36%).
