Proteasome inhibition is a novel, targeted approach in cancertherapy. Both natural and synthetic proteasome inhibitors selectivelypenetrate cancer cells, disrupting the orderly destruction of key regulatoryproteins involved in tumorigenesis and metastasis. Disrupting theorderly destruction of regulatory proteins causes an imbalance of theseproteins within the cell, which interferes with the systematic activationof signaling pathways required to maintain tumor cell growth and survival;therefore, cellular replication is inhibited and apoptosis ensues.
