Reduced proteasome activity in MPM cell lines with increased sensitivity to bortezomib. (A) Chymotrypsin-like, trypsin-like, and caspase-like specific activities of proteasomes were assessed in cell extracts as described in the Materials and Methods and expressed on a per-cell basis. Data are the mean of six independent measurements. **P < 0.01. (B) Correlations of 26S proteasome peptidase activities and EC50 values relative to the apoptotic effect of bortezomib in MPM cell lines.
