Effects of repeated exposure to 50 Hz electromagnetic field on breast cancer cells.
This in vitro study exposed two human breast cancer cell lines to a 50 Hz ELF-EMF (20 mT) for 3 hours/day for up to four days. The authors report reduced viability and apoptosis-related findings in MDA-MB-231 cells, with no significant viability change in MCF-7 cells. Cell-cycle effects differed by cell line, suggesting cell-type-specific responses under the tested conditions.
Key points
- In vitro exposure was 50 Hz ELF-EMF at 20 mT for 3 hours per day for up to four days.
- Viability reportedly decreased in MDA-MB-231 cells compared with non-exposed controls.
- MCF-7 cells reportedly showed no significant change in viability under the same exposure.
- MDA-MB-231 cells showed G1 phase arrest and an increased sub-G1 population after repeated exposure.
- Fluorescent staining suggested apoptotic cell death in MDA-MB-231 cells.
- MCF-7 cells showed an increased S-phase fraction and no reported morphological changes.
