The synthetic triterpenoid CDDO-Im-induced apoptosis of patient-derived AML blasts: 11/25 AMLs were highly sensitive, while the remaining were moderately sensitive to CDDO-Im. The addition of TRAIL significantly potentiated the cytotoxic effect of CDDO-Im, through mechanisms involving the induction of TRAIL-R1/TRAIL-R2 and downmodulation of TRAIL-R3/TRAIL-R4. Biochemical studies showed that CDDO-Im: induced a rapid and marked GSH depletion and antioxidants (GSH or NAC) completely inhibited its pro-apoptotic effect; sequentially activated caspase-8, -9 and -3; caspase inhibitors partially protected AML blasts from CDDO-Im-induced apoptosis; resistance of AML blasts to CDDO-Im-induced apoptosis correlated with low caspase-8/FADD and high Bcl-X-L expression in leukemic blasts.
