Ectopic overexpression of Smac/DIABLO enhanced Epo B– or Apo-2L/TRAIL–induced cytosolic accumulation of cyt c and Smac/DIABLO in Jurkat cells.
Jurkat cells were transiently transfected with either the control vector (pcDNA3.1 Zeo) or pcDNA3.1-expressing Smac/DIABLO (pcDNA3.1 Smac). Twenty-four hours after transfection, cells were treated with 10 nM Epo B (A) or 2.5 ng/mL Apo-2L/TRAIL (B) for 24 hours. Following this treatment, the S-100 fractions were obtained from the harvested cells and used for the immunoblot analyses for the cytosolic cyt c and Smac.
