BCL2 is regulated by C/EBPβ. MM cells were transfected with EV, (A) DN-C/EBPβ, or (B) WT-C/EBPβ. Transfected cells were selected for 10 days with G418 (500 μg/mL). Lysates of transfected cells were subjected to Western blotting using anti-BCL2 antibody. β-Actin was used as a loading control. Vertical lines have been inserted to indicate a repositioned gel lane.
