CPT induces apoptotic cell death in tumor cells. Rh30 cells grown in 100-mm dishes (2 × 106 cells per dish) were treated with indicated concentrations of CPT (0–20 μmol/L) for 72 hours (A), or with 10 μmol/L CPT for indicated time (B), and then stained with Annexin V-FITC and PI, followed by flow cytometric analysis. Results (A and B) are presented as mean ± SE (n = 3). b, P < 0.01, difference versus control group.
