Supplementary Figures 1 - 6 from Threshold Levels of ABL Tyrosine Kinase Inhibitors Retained in Chronic Myeloid Leukemia Cells Determine Their Commitment to Apoptosis

PDF file - 1469K, Different ABL TKIs demonstrate potency differences in relative cellular and biochemical target inhibition (S1); Incomplete restoration of BCR-ABL signaling activity following washout of dasatinib or ponatinib tracks with intracellular drug retention and commitment to apoptosis in LAMA cells (S2); Incomplete restoration of BCR-ABL signaling activity following washout of nilotinib, imatinib, or DCC-2036 tracks with intracellular drug retention and commitment to apoptosis in LAMA cells (S3); BCR-ABL signaling is partially attenuated in conditions of continuous low concentrations of ABL TKIs that induce apoptosis (S4); Commitment to apoptosis in primary CML cells tracks with intracellular retention of ABL TKIs (S5); Intracellular retention of dasatinib, nilotinib, and imatinib is reduced following washout in primary CML cells harboring the resistant BCR-ABLT315I mutant (S6).
