Ganoderma lucidum (Fr.) Karst is a traditional Chinese herb that has been widely used for centuries to treat various diseases including cancer. Herein, an ethanol-soluble and acidic component (ESAC), which mainly contains triterpenes, was prepared from G. lucidum and its anti-tumor effects in vitro were tested on human breast cancer cells. Our results showed that ESAC reduced the cell viability of MCF-7 and MDA-MB-231 cells in a concentration-dependent manner with IC50 of about 100 μg/mL and 60 μg/mL, respectively. DNA damage was detected by Comet assay and the increased expression of γ-H2AX after ESAC treatment was determined in MCF-7 cells. Moreover, ESAC effectively mediated G1 cell cycle arrest in both concentration- and time-dependent manners and induced apoptosis as determined by Hoechst staining, DNA fragment assay and Western blot analysis in MCF-7 cells. In conclusion, ESAC exerts anti-proliferation effects by inducing DNA damage, G1 cell cycle arrest and apoptosis in human breast cancer cells.
