Our results show for the first time that vorinostat and the BH3 mimetic ABT-737 can cooperate to induce cell death in DLBCL in a BCL-2 family protein-dependent manner, a finding that is similar to the effects of these compounds in other types of cancer [5]–[7], [13], [25], [27], [29]–[34], [43], [44]. Here, BCL2 is linked to diffuse large B-cell lymphoma.
