Introduction: Breast cancer is the most common metastatic malignancy and the second leading cause of death in women. Recently, extremely low-frequency electromagnetic fields (ELF-EMFs) seem to modulate the rate of proliferation and enhance apoptosis and are considered as an emerging approach to cancer therapy. Despite recent success in the electromagnetic fields, the results are still neither definitive nor even contradictory.  
Methods: In this
udy, induction of apoptosis was considered as one of the possible mechanisms of ELF-EMFs on cancer inhibition. Brea cancer cell lines were exposed to a 1 Hz, 100mT ELF-EMF (2h/day) for five days. the apoptosis rare of both the exposure and sham exposure groups was determined by flow cytometry. The expression levels of Bax and Bcl-2 were evaluated by real-time PCR.
Results: The mRNA expression levels of Bax were increased; while the expression of Bcl-2 showed a decrease in MDA-MB231 cells exposed to 1Hz EMF compared with sham exposure. Moreover, the ratio of Bax/Bcl2 was significantly increased in comparison to the sham exposure. The increased Bax/Bcl-2 ratio induces cell apoptosis.
Conclusions: It is sugge
ed that ELF-EMF is a new adjuvant therapeutical method that may contribute to anti-cancer and cancer therapy research.
