Here we show that a strong hyper-phosphorylation/activation of ERK1/2, Akt Ser473, and 40S ribosomal protein S6 (rpS6) is detectable in imatinib-resistant KCL22 and K562 CML cells as compared to the -sensitive cell variants. The gene discussed is AKT1; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
