چکیده انگلیسی
Danggui-Shaoyao-San (DSS), a traditional Chinese medicine used for centuries for the enhancement of women's health, has been shown to display therapeutic efficacy on senile dementia. In the present study, using a rat pheochromocytoma (PC12) cell line, the effect of DSS on hydrogen peroxide (H2O2) induced apoptosis was studied. The apoptosis in H2O2-induced PC12 cells was accompanied by downregulation of Bcl-2, upregulation of Bax, the release of mitochondrial cytochrome c into cytosol, and sequential activation of caspase-9 and -3. DSS was able to suppress all these changes and eventually protected against H2O2-induced apoptosis. Taken together, these results suggest that treatment of PC12 cells with DSS can block H2O2-induced apoptosis by the regulation of Bcl-2 family members, as well as suppression of cytochrome c release and caspase cascade activation.
