Toxicity of the micellar DM-PIT-1 and its combination with TRAIL against TRAIL-resistant U87MG cells. Cells were treated with indicated amounts (in µM) of plain micelles modified with TRAIL (1); micellar DM-PIT-1 (2), or micellar DM-PIT-1 modified with TRAIL (3). The amount of lipid in all wells was kept constant at 2.5 mg/ml by adding empty micelles. Cell viability was determined after 24 hr using the MTT assay. Data represent the mean ± SD of three independent experiments and are expressed relative to the untreated control (*P<0.05, **P<0.01).
