PURPOSE: Breast cancer is one of the most common malignant tumors in women all over the world. Many of these women resist the common treatments. Therefore, it is important to find new products to increase the efficacy of the treatment process. Legume beans, with their various pharmacological properties, can be regarded as a sensitizer when they are combined with radiation. The present study strove to survey the radio-sensitivity effect of proteins isolated from mung bean aqueous extract on the human breast adenocarcinoma cell line (MCF-7), human cervical cancer cells (Hela) and the human dermal fibroblast cell line.

MATERIALS AND METHODS: The mung bean aqueous extract was partially purified by ammonium sulfate. At first, various concentrations of the extracts were used to evaluate the inhibitory activity by MTT cell proliferation assay.

RESULTS: The results showed that MCF-7 cells and Hela cells were inhibited by an ICvalue of less than 250 and 411 µg/ml, respectively, but it proved to have a proliferation effect on the fibroblast cells. Then, the cells were incubated with 250 µg/ml extract and exposed to 2, 4, and 6 Gy of X-ray radiation. The percentage of the cell survival was investigated through MTT and the clonogenic assay. Apoptosis was measured using acridine orange/ethidium bromide staining. The results demonstrated that the treated MCF-7 cells and Hela cells had significant radio-sensitivity compared with the results of the control group in radiation dose manner in all MTT, clonogenic, and apoptosis assays. In contrast,the treated fibroblast showed a protective effect against radiation.

CONCLUSION: The results suggest that mung bean proteins have the capacity to be regarded as a radio-sensitizer for breast cancer. Our results also indicated that it could be worth to investigate on mung bean proteins further and they should be tested in animal models for being treated in radiotherapy.
