Effects of THL on the proliferation of NB4 leukemia cells. The cells were treated with increasing concentrations of THL (0.375–3 mg/mL) or PBS only for 72 h, and cell viability was determined by trypan blue exclusion. Data (mean ± SE, duplicate) are expressed as a percentage of the PBS-treated control. SE: standard error.
