摘要

In this study, the effect of aucubin on H2O2-induced apoptosis was studied by using a rat pheochromocytoma (PC12) cell line. We have analyzed the apoptosis of H2O2-induced PC12 cells, H2O2-induced apoptosis appeared to correlate with lower Bcl-2 expression, higher Bax expression and sequential activation of caspase-3 leading to cleavage of poly-ADP-ribose polymerase (PARP). Aucubin not only inhibited lower Bcl-2 expression, high Bax expression, but also modulated caspase-3 activation, PARP cleavage, and eventually protected against H2O2-induced apoptosis. These results indicated that aucubin can obstruct H2O2-induced apoptosis by regulating of the expression of Bcl-2 and Bax, as well as suppression of caspases cascade activation.
