A. Western blot analysis of BCL-2 expression in the c-MYC-expressing JR1 cells after transduction with either Ad-BCL2 or Ad-VC. B. Cytotoxicity assay of the c-MYC-expressing cells after transduction with different combinations of adenoviral vectors. Cells were pretreated for 24 h with either Ad-VC (m.o.i. 5, circles) or Ad-BCL2 (m.o.i. 5, diamonds) and then exposed to increasing m.o.i.s of either Ad-VC (dashed line) or Ad-p53 (solid line).
