Baishouwu (Cynanchum Auriculalum Royle ex Wight), a traditional Chinese herbal medicine, is used as a traditional anti-aging remedy in China. Previous studies suggested Baishouwu has multiple pharmacological actions. In this study, the total glycosides extracted from Baishouwu (CA/TG) were evaluated for its potential anti-tumor activity and mechanism on several human breast and prostate cancer cell lines. In [3H] thymidine incorporation assay, CA/TG inhibited the proliferation of cancer cells in a dose-dependent fashion. It also displayed anti-androgen activity on androgen sensitive cell line assessed by reporter gene assay. The morphological examination of CA/TG treated cells revealed overall shrinkage of nucleus, chromatin condensation and small nuclear fragments by DAPI staining, the characteristic pattern of DNA ladders were observed in cells exposed to CA/TG, indicating the involvement of apoptosis in its action. These results suggested that the CA/TG has preferred cytotoxicity against the cancer cells, and the action was due to its ability of preventing cell proliferation and inducing apoptosis.
