R-568-induced apoptosis is attenuated by altered Bcl-xL expression in prostate cancer cells. A LNCaP cells and its two sublines, LNCaP/Bclxl and LNCaP/LN11, were seeded in 12-well plates and treated with R-568 at the indicated doses for 48 h. The control cells received no treatment. Cells were harvested at the end of experiment and stained in 0.4% trypan blue solution. The dead (blue) cells were counted and the average of death rate in each well was presented. Data represent three different experiments. The asterisk indicates a significant difference (P < 0.05) between R-568 treatment and the control. B LNCaP/Bclxl and LNCaP/LN11 cells were treated with R-568 at indicated doses for 24 h and then harvested for protein extraction. Equal amounts of cellular proteins were subjected to Western blot assay to assess caspase-3 processing and PARP cleavage. Primary antibodies used are indicated on the left side. Actin blot served as the protein loading control. Data represent two different experiments.
