(A) Activation of cleavage of caspase-3, caspase-9 and PARP. Whole cell lysate was used for Western blot analysis. β-actin was probed to show equal loading of total protein. (B) DLCL2 cells treated with caspase family inhibitor (Cfamily Inhibitor), Z-VAD-FMK, caspase-9 inhibitor (C9 Inhibitor), Z-LEHDFMk, caspase-3 inhibitor (C3 Inhibitor), Z-DEVD-FMK, and/or ApoG2 (1000 nM). * indicates p < 0.05 when ApoG2 and caspase inhibitor combined treatment compared with corresponding either caspase alone treatment or ApoG2 alone treatment.
