Western blot analysis show changes in caspase 9, 8, and 3. (A) Digitoxin and D6-MA induced differential cleavage of caspase 9. Digitoxin caused pro-caspase 3 to drop at 50 nM, while D6-MA caused pro-caspase 3 to drop at 20 nM. (B) Quantification of cleaved caspase 9 blots shows fold change in cleavage following treatment. (C) Quantification of cleaved caspase 8 blots shows fold change in cleavage following treatment. (D) Quantification of pro-caspase 3 blots shows decrease in quantity following treatment; (*) indicates significantly different from control, (†) indicates significantly different from digitoxin.
