HD suppresses the proliferation of T-ALL cells. (a) Chemical structure of HD. (b) T-ALL cells were exposed to various concentrations of HD (0, 10, 20, 30, 40, 50 µM) for 24, 48 and 72 h. MTT analysis was used to determine the cell viability. (c) EC50 values of HD in T-ALL cell lines were calculated by GraphPad Prism. The data represent three independent experiments. (d) Normal human lymphocyte cell CAM-191were treated with different concentrations of HD (0, 10, 20, 30, 40, 50 µM) for 48 h. The cell viability was examined by MTT assay.
