FIG. 5.
TRAIL and Ad5/35-TRAIL trigger caspase activation in HL-60 and HL-60/Vinc cells: (A) caspase-8, (B) caspase-10, (C) caspase-9, and (D) caspase-3. Aliquots (50 μg of protein per lane) were separated by 10% SDS–PAGE and subjected to Western blot analysis as described in Materials and Methods. Lanes 1–4 in each panel are HL-60/control, HL-60/Ad5/35 vector, HL-60/TRAIL, and HL-60/Ad5/35-TRAIL, respectively. Lanes 5–8 in each panel are HL-60/Vinc/control, HL-60/Vinc/Ad5/35 vector, HL-60/Vinc/TRAIL, and HL-60/Vinc/Ad5/35-TRAIL, respectively.
