Pulsed and Discontinuous Electromagnetic Field Exposure Decreases Temozolomide Resistance in Glioblastoma by Modulating the Expression of O-Methylguanine-DNA Methyltransferase, Cyclin-D1, and p53.
This in vitro study evaluated 50 Hz, 70 G electromagnetic field exposure in combination with temozolomide (TMZ) in T98 and A172 glioblastoma cell lines. The authors report that EMF plus TMZ increased cell death and reduced migration potential compared with controls. They also report increased p53 gene expression and decreased cyclin-D1 protein, with MGMT protein expression observed after treatment in T98 but not A172 cells.
Key points
- The study tested 50 Hz (70 G) EMF exposure in TMZ-treated T98 and A172 glioblastoma cell lines.
- Combined EMF and TMZ was reported to enhance cell death compared with controls.
- Combined EMF and TMZ was reported to decrease migration potential in both cell lines.
- The authors observed p53 gene overexpression relative to controls.
- Cyclin-D1 protein was reported to be downregulated compared with controls.
- MGMT protein expression after treatment was reported in T98 cells but not in A172 cells.
- The authors suggest EMF exposure could partially affect TMZ resistance in T98 cells.
