Abstract:

Breast cancer is a tremendous threat to humans in many countries, and thus we need to find safe and effective drugs for treatment. Ginsenoside Rh4 has been reported to be present in processed ginseng. However, few studies have focused on its anti-tumor activity. In this study, we investigated the inhibitory effects of ginsenoside Rh4 on MCF-7 breast cancer cells and the pathways that promote apoptosis in vitro. To study the effect of ginsenoside Rh4 in vivo, xenograft models were randomly divided into 3 groups (the control group, 10 mg/kg/d Rh4, 20 mg/kg/d Rh4, n = 10 per group), the ginsenoside Rh4 injection method was i.p. The results showed that ginsenoside Rh4 effectively inhibited proliferation, arrested the cell cycle in S phase and induced apoptosis in MCF-7 cells by flow cytometry. Morphological changes caused by ginsenoside Rh4-induced apoptosis were also observed by Hoechst 33342 staining. Western-blot analyses indicated that the apoptosis-inducing effects of ginsenosideRh4 were associated with the external pathway by decreasing Bcl-2, increasing Bax, and activating caspase-8, -3 and PARP. Moreover, ginsenoside Rh4 significantly inhibited the growth of MCF-7 tumor cells in vivo. These results suggested that ginsenoside Rh4 could be a potentially effective anti-tumor drug for breast cancer.
