The fusion protein Bcr–Abl, which is the molecular cause of chronic myelogenous leukemia (CML) interacts in multiple points with signaling pathways regulating the cellular adhesivity and cytoskeleton architecture and dynamics. We explored the effects of imatinib mesylate, an inhibitor of Bcr–Abl protein used in front-line CML therapy, on the adhesivity of JURL-MK1 cells to fibronectin and searched for underlying changes in the cell proteome. As imatinib induces apoptosis of JURL-MK1 cells, we used three different caspase inhibitors to discriminate between direct consequences of Bcr–Abl inhibition and secondary changes related to the apoptosis. Imatinib treatment caused a transient increase in JURL-MK1 cell adhesivity to fibronectin, possibly due to the switch off of Bcr–Abl activity
