Effects of triptolide on the proliferation and apoptosis of cell line A549 in human lung adenocarcinoma / 中国药理学通报

ABSTRACT

Aim To investigate the effects of triptolide on the proliferation and apoptosis of cell line A549 in human Lung Adenocarcinoma. Methods MTT, DNA fragmentation assay, fluorescence stain and flow cytometric analysis were carried out.Results Triptolide notably reduced the survival rate of A549 cells, and inhibited the proliferation of A549 cells. The 50 % inhibitory concentration (IC50) for 72 h was 75 nmol?L-1 and it arrested the cell cycle at S phase at the concentration of 14 nmol?L-1 (P
