Finally, we tested the induction of caspases 3/7 on both tumor cell lines with 10 μM of QS-21 and 100 μM of QA during 24 h, resulting in a significant induction of the activity of caspases 3/7 compared with the negative control (P < 0.0001) as seen in Fig. 7. This evidence concerns the gene CASP3 and neoplasm.
