Figure 2 : Treatment with PCI-24781 and bortezomib result in caspase mediated apoptosis in neuroblastoma.

Cells were incubated with vehicle (C), 1 μM PCI-24781 (P), 10 mMbortezomib (B), or the combination (P+B)for 48 hrs and cell
lysates were collected and run on western blots to evaluate for cleaved caspase 3 and PARP.
