Synergistic interaction of inhibitors of NF-κB or antiapoptotic proteins with IBR+VEN combination. Synergistic interaction of inhibitors of NF-κB (BMS-345541, Bortez, and Carfilzomib) and antiapoptotic proteins (A1210477(A121), BH3I-1, UMI-77, and YM155) was determined by calculating Bliss predicted and actual cytotoxicity of individual inhibitors with IBR (0.1 μM) + VEN (25 nM) combination. The statistical significance was determined by ANOVA. *P < .05, **P < .01.
