BCL2 and diffuse large B-cell lymphoma: Despite the robust anti-proliferative effect of BETi in DLBCL cell lines, BETi (JQ1) alone had only a limited effect on cell survival, while a pro-apoptotic effect of BCL-2 inhibitor (ABT-199) varied with nearly 90% decreased survival of WT-MYC cell line U2932 and the DHL cell line DOHH2 as compared to a relatively moderate 50% decreased survival in THL cell line Val.
