Z-VAD-FMK effectively delayed the apoptosis of venetoclax and chidamide in t-FL cells. A DOHH2, B SU-DHL-4, C RL, and D SC-1 cells were pretreated with 100 μM pan-caspase inhibitor Z-VAD-FMK for 2 h and treated with the indicated concentrations of ABT199, CS055, and the combination of the two drugs for 24 h. Data were represented as mean ± SD. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 and ns (not significant) by unpaired t test
