Nutlin3a was able to induce apoptosis and decrease viable cell counts not only in proliferating (EC50 = 7.1 ± 1.6 μM) but also in quiescent (EC50 = 14.6 ± 2.1 μM) CD34+ CML cells obtained from BC CML patients (Figure 3, n = 8, Table 1). The gene discussed is CD34; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
