ABSTRACT

The extremely low frequency electromagnetic field (ELF-EMF) is emerging as a novel approach in cancer treatment. This study evaluated the impact of daily exposure to 50 Hz EMF on breast cancer cells in vitro. The MDA-MB-231 and MCF-7 cells were exposed to EMF (50 Hz 20 mT, for 3 hours per day for up to four days) and examined for cell vaibility. The effect of daily ELF-EMF exposure on cell cycle progression and cell death was further investigated. The result revealed that the consecutive exposure to 50 Hz EMF at 20 mT remarkably decreased the viability of MDA-MB-231 compared to the non-exposed group, while it had no significant effect on MCF-7 cells. The ELF-EMF exposure induced G1 phase arrest along with the increase in sub-G1 cell population in MDA-MB-231. Moreover, repeated exposure to 50 Hz EMF promoted cell cycle progression in MCF-7 by increasing the percentage of cells in the S phase. The fluorescent staining revealed that daily exposure of ELF-EMF induced apoptotic cell death in MDA-MB-231, but no morphological change was observed in MCF-7 cells. The results showed that repeated daily exposure to 50 Hz EMF exhibited anti-proliferative activity against invasive breast cancer cells by impairing cell cycle progression and inducing cell death.
