BSO triggers activation of ASK1 and JNK and induces phosphorylation of BIM EL and MCL1. A, The phosphorylation of ASK1 was determined by immunoblotting. HL60 cells were treated with ATO/BSO or ATO in the presence or absence of NAC or DTT for 12 h. B, The phosphorylation of JNK, BIMEL, and MCL1, and cleavage of caspase 3 and PARP, were determined by immunoblotting. HL60 cells were treated with ATO/BSO or ATO in the presence or absence of NQDI1 (10 μM) for 12 h. A typical result of 3 independent experiments is shown.
