Kinetic effect of proteasome inhibition and apoptosis induction by Cd1, Cd2 and Cd3 in MDA-MB-231 cells. MDA-MB-231 cells were exposed to 20 μM of Cd1, Cd2 and Cd3 for the indicated times, followed by the proteasomal chymotrypsin-like activity assay (A), Western blot assay (ubiquitin, PARP, IκB-α and β-actin, B), and the apoptosis morphologic changes (C.) Columns, mean+/−SE of three independent experiments; bars, SD.
