  • NOTE: Cells expressing wild-type and mutant WT1A were incubated in the presence of 1,000 and 0 ng/mL tetracycline (6 ng/mL tetracycline for WT1A). Where indicated, WT1A-expressing cells were infected with the MIGR1 retroviral vector expressing GFP, GFP + VDAC1, or VDAC2. At the indicated time, floating cells were combined with adherent cells, labeled with fluorescein or TMR red by TUNEL reaction, and processed by FACS analysis.
