NSC697923 induces cell death of primary DLBCL cells. Primary cancer cells prepared from tumor specimens of 2 DLBCL patients were seeded at 4.5 × 105 cells/mL in RPMI medium supplemented with 20% FBS and treated with the indicated concentrations of NSC697923 for 24 hours. The apoptotic cells were analyzed as described in Figure 5E. Shown are the averages from 2 independent experiments.
