Synergistic cell death induced by loperamide plus bortezomib is neither apoptosis not autophagic cell death 14 2. Intracellular Ca2+ influx is involved in the combined treatment-induced vacuolation 27 3. Combined treatment with loperamide and bortezomib induces ER stress, and CHOP is critically involved in the cell death by loperamide plus bortezomib 33 4. ROS generation is important for the cell death induced by loperamide plus bortezomib 42 5. Noxa is also critical factor for loperamide plus bortezomib-induced cell death 46 6. Disruption of aggresome formation may be involved in the cell death induced by loperamide and bortezomib 50 7. Combined treatment with loperamide and proteasome inhibitors does not induce cell death in normal colon cells 56 IV. DISCUSSION 60 V.
