BACKGROUND/AIM:
Glioblastoma multiforme is an aggressive primary tumor that arises in the glial cells of the brain. Standardized first-line treatment has considerable morbidity and less than one-year median survival after intervention. Ultra-low intensity electromagnetic fields have been shown to interact with biological organisms without anticipated deleterious side-effects. The aim of the study was to determine if a novel, non-invasive application of non-ionizing radiation has an inhibitory effect on proliferation of glioblastoma multiforme cells.
MATERIALS AND METHODS:
U-87 MG cells were continuously exposed for 54 h to an electromagnetic field tuned to simultaneously interact with DNA/RNA oligonucleotides (mutated alpha-kinase 2 gene/Hsa-miR-381-5p respectively) and proteins (HSP70/CHI3L1).
RESULTS:
Exposed cells demonstrated a significant inhibition of cell growth and concurrent increase in cell death.
CONCLUSION:
This technology induces cell death by novel non-cytotoxic mechanisms unlikely to induce side-effects in patients; can be customized for individual tumors and may contribute to the emerging strategy of personalized medicine.
