a Micrographs of MDA-MB-468 cells treated as indicated for 24 h showing cytotoxicity of tcyDTDO and TRAIL and prevention of cell death by the caspase inhibitor Q-VD-OPH (10 µM). b MTT assays were performed on MDA-MB-468 and BT474 cells with indicated treatments for 72 h. c Immunoblot analysis of MDA-MB-468 cells treated as in a. d Immunoblot analysis of 012/LVM/fLuc cells treated for 24 h as indicated. e Model for how DDAs and TRAIL reduce the levels of PERK, EGFR, PDK1, and Akt by inducing their caspase-dependent degradation.
