Effects of Triptolide on HL-60 Cell in vitro and in vivo / 中国药理学通报

Aim To study the effects of Triptolide (TPL) on HL-60 cells in vitro and in vivo.Methods MTT was used to examine the effects of TPL on proliferation of HL-60 cells;TUNEL assay was used to detect apoptotic cells.The effect of TPL on xenograft growth of HL-60 cells was evaluated by tumor inhibition rate.Results In vitro TPL inhibited the proliferation and induced apoptosis of HL-60 cells in a dose-dependent manner.In vivo TPL inhibited xenograft growth of HL-60 cells with the highest inhibition rate of 53.5%.Conclusion TPL is able to inhibit the proliferation of HL-60 cells and induce apoptosis of HL-60 cells in vitro and in vivo.
