Abstract

Aloe-emodin is a Hydroxyanthraquinone that exists in Aloe Vera leaves and has been known to have antitumor effects. Various studies have mentioned the biologic effects of Aloe Vera such as antiviral, antimicrobial and some hepato-protective effects. Recently its antitumor effects have attracted many researchers. Breast cancer is the most common malignancy in women, accounting for 30 of all female cancers and < 1 of all cancer cases in men. Breast cancer also is responsible for 15 of cancer deaths in women. The aim of the present study was to investigate the anti-cancer effect of aloe-emodin on human breast cancer MCF-7 cell line. Materials and Methods: MCF- 7cellswere cultured in RPM Imedium with 10 fetal bovine serum (FBS). The cytotoxic effect of different concentrations (5, 10, 25, 50, and 100 μM) of Aloe-emodin on cultured cells were evaluated by MTT assay at different times (24, 48, 72 h). Apoptosis and CD95 (Fas) expression were analyzed by flow-cytometry using an Annexin V-FITC/PI kit and Fas (CD95) kit according to the manufacturer's protocol. Results: Aloe-emodin decreases the viability of MCF-7 cell line in a time and dose dependent manner, so that the most effective concentration of this substance was 100μM and 72h after treatment. According to the data of Fas (CD95) expression and Annexin-PI, the highest apoptosis induction rate was seen in 100μM and 72 h. Conclusion: The findings of the present study indicated that Aloe-emodin has some antitumor effects and can be used in the treatment of breast cancer. However, further investigationof its cytotoxic effects against tumor cells, both in vitro and in vivo, is recommended.
