As mentioned above, miR-19, which belongs to the miR-17-92 cluster, controlled multiple regulators (PP2A, PRKAA1, BIM, and PTEN) of PI3K signaling which resulted in increased phosphorylation of AKT and the ribosomal S6 protein, which subsequently promoted survival of T-ALL cells [44]. The gene discussed is AKT1; the disease is acute lymphoblastic leukemia.
