Raddeanin A suppresses lung cancer cell proliferation via induction of apoptosis and increased production of ROS

At present, in vitro cell experiments have confirmed that RaddeaninA can effectively inhibit the proliferation of some tumor cells, but the effect of RaddeaninA on lung cancer cells has not been observed. Therefore, this study explored its effect on lung cancer cells and its mechanism of action. Human lung cancer cell lines were treated with serum-free medium and varied concentrations of Raddeanin A. Cell proliferation and apoptosis were determined using MTT, and flow cytometric assays, respectively. The intracellular level of ROS was determined using DCFH-DA assay. Protein and mRNA expressions of bax, bcl-2 and cyt c were measured using Western blotting and qRT-PCR. RaddeaninA treatment can promote PC-9 cell apoptosis in a time and dose-dependent manner (p
