Novel proteasome inhibitors in the management of MM Discussion Point
Cellular Impact of Proteasome Inhibition in Nonclinical Studies1-4 1. Proteasomes are enzyme complexes that degrade intracellular proteins in a regulated manner in all cells, both healthy and cancerous 2. Cancer cells depend upon proteins regulated by the proteasome for proliferation, metastasis and survival 3. Inhibition of the proteasome by bortezomib prevents the degradation of intracellular proteins, affecting multiple signaling cascades within cells 4. The disruption of signaling cascades in cancer cells can lead to cancer cell death and inhibit tumor growth 1 Invest New Drugs 2000;18:109-21. 2 Physiol Rev 2002;82:373-428. 3 Sci Am 2001;284:63-73. 4 Cell 1998;92:367-84.
