Figure 2. Analysis of caspase activity. Pancaspase activity (A) and caspases 9, 8 and 3 activity (B) in Y79 cells treated with pentoxifylline (PTX; 4 mM), carboplatin (CPt; 30 μg/ml) or their combination for 24 h. The results are presented as means±standard deviation. **p<0.007 [CPt, PTX or PTX+CPt groups compared to untreated control group (UCG)] *p<0.001(CPt, PTX or PTX+CPt compared to the UCG).
