Doxorubicin- and etoposide-induced cell death. (A) HBL-2 cells were incubated with or without doxorubicin at a concentration of 1.6 or 3.2 µM, and their cell viability decreased in a dose- and time-dependent manner. *P=0.0002; **P<0.0001; ***P=0.0001. (B) HBL-2 cells were incubated with or without etoposide at a concentration of 10 or 30 µg/ml, and their cell viability decreased in a time- dependent manner, but not in a dose-dependent manner. *P=0.0044. Data are representative of two independent experiments. DOX, doxorubicin; NS, not significant.
