U266 cells (1 × 106/mL) were treated with indicated concentrations of resveratrol, bortezomib, and thalidomide alone or in combination for 24 hours at 37°C. Cells were stained with a live/dead assay reagent for 30 minutes and then analyzed under a fluorescence microscope as described in “Materials and methods.” The results shown are the percentage of apoptosis and are representative of 3 independent experiments. Standard deviations between the triplicates are indicated.
