Investigating the expression changes of several key genes in prostate cancer cells under exposure to the ELF pulsed electromagnetic fields.
This in vitro study exposed DU-145 prostate cancer cells to extremely low-frequency pulsed electromagnetic fields (ELF P-EMF) at different intensities and times. The authors report increased cell mortality and apoptosis with higher intensity (22.6–35 mT) and longer exposure. They also report gene-expression changes consistent with pro-apoptotic and tumor-suppressive signaling (increased PTEN and BAX; decreased MIR-21 and somewhat decreased BCL-2).
Key points
- The study is an in vitro experiment using the DU-145 prostate cancer cell line.
- Cells were exposed to ELF pulsed electromagnetic fields at 22.6 mT and 35 mT with varying exposure times.
- Cell viability was assessed by MTT and apoptosis/necrosis by flow cytometry.
- Higher intensity and longer exposure were reported to significantly increase cancer cell mortality.
- Exposure was reported to induce apoptosis in DU-145 cells.
- PTEN and BAX expression were reported to increase after exposure compared with controls.
- MIR-21 expression was reported to decrease, and BCL-2 expression was reported to decrease to some extent.
