Effects of sequential PI therapy in combination with RAM2061 on markers of apoptosis. MM cells were incubated with RAM2061 (50 or 100 nM) for 48 h with or without sequential PI treatment. Bortezomib or carfilzomib was added either a 6 h (denoted by **) or b 24 h (denoted by *) prior to cell harvest (Bor: 3 nM (MM.1S), 5 nM (JJN3 and RPMI-8226), 15 nM (ALMC-2), Carf: 20 nM). Immunoblot analysis for PARP (lower band = cleaved PARP), cleaved caspases 3, 8, and 9 (ClCasp 3, 8, 9) is shown. β-tubulin was used as a loading control. Blots are representative of three independent experiments
