Spautin-1 is a novel and potent autophagy inhibitor, which enhances imatinib-induced (MI) apoptosis in chronic myeloid leukemia. Autophagy has been proposed to play a role in MI resistance. Spautin-1 markedly inhibits IM-induced autophagy in CML cells by downregulating Beclin-1. Spautin-1 enhances IM-induced CML cell apoptosis by reducing the expression of the anti-apoptotic proteins Mcl-1 and Bcl-2. Spautin-1 enhances IM-induced apoptosis by inactivating PI3K/AKT and activating downstream GSK3β, leading to downregulation of Mcl-1 and Bcl-2, which represents a promising approach to improve the efficacy of IM in the treatment of patients with CML.
