Characterization of the translational regulation of BIM 3’ UTR

BIM (BCL-2-interacting mediator of cell death) plays a central role in the regulation of the intrinsic apoptotic pathway by controlling the delicate balance between the induction of apoptosis and cell survival. The dysregulation of BIM expression potentially results in diseases including cancer. Gen...
