Figure 1

THL inhibited the growth of MCF-7, MDA-MB-231, and BT-474 breast cancer cells. Cells were treated with various concentrations of THL (0.75–6 mg/mL) or PBS only as a control for 72 h and cell viability was determined by the SRB assay. Data (mean ± SE in triplicate) are expressed as a percentage compared to the PBS-treated control.
