ABSTRACT |
Objectives: To investigate the anti-cancer effect of Palbohoichoon-tang (PBHCT) extracts.
Methods : The cell viability was assessed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MMT) assay and cell morphological changes were microscopically analyzed after staining with 10 μM 2-[4-amidinophenyl]-6-indolecarbamidine dihydrochloride (DAPI) and TUNEL. We also analyzed expression of Bcl2, BclxL, Bax, procaspase-3, procaspase-9, and procyclic acidic repetitive protein (PARP) by western blot method.
Results: Observations showed that PBHCT induced the apoptotic cell death proved by increased sub-G1 phase cell population, apoptotic body formation and chromatin condensation. Western blot analysis of total cell lysates revealed that the PBHCT induced cleavage of caspase-9, caspase-3 and poly (ADP-ribose) polymerase (PARP). In addition, PBHCT dose-dependently increased the activity of caspase-9, caspase-3 and PARP-1. Furthermore, PBHCT reduced anti-apoptotic Bcl2, BclxL expression which contributed to the loss of mitochondrial membrane potential and the activations of caspase-9 and caspase-3.
Conclusions: These findings suggest that PBHCT exerts anti-cancer effects on human neuroblastoma SH-SY5Y cells by inducing apoptotic death via down-regulation of anti-apoptotic proteins such as Bcl2 and BclxL, up-regulation of pro-apoptotic proteins such as Bax, and activation of caspase cascades and PARP-1. |
