Research Abstract |
We in this study investigated the molecular and biologic effects of galectin-3 (Gal-3) which is specifically induced by tumor-microenvironment in leukemic cells of chronic myelogenous leukemia (CML). Gal-3 promoted cell proliferation of leukemic cells via the activation of ERK and AKT as well as the inhibition of extracellular SERPINA1-albumin complex. Gal-3 also induced the expression of anti-apoptotic MCL-1 and caused the resistance to molecular targeted agents and genotoxic agents in CML cells. Interestingly, Gal-3 expression promoted the lodgment of leukemic cells in bone marrow in vivo. Finally, our study revealed that the combinatory use of protein phosphatase-2 activator in addition to the currently utilized molecular targeted agents, such as imatinib or dasatinib, was effective in overcoming those series of leukemia-promoting effects of Gal-3,
