Abstract
"Background: p53 acts as a transcription factor to regulate the expression of genes that modulate various cellular activities. The proliferation of cancer cells has been inhibited under the exposure to low-intensity (18 peak-to-peak voltage) and intermediate-frequency (100 KHz) electric fields generated between 2 capacitive electrodes. Therefore, the aims of this study were to observe the molecular mechanism of cell death caused by noncontact electric field exposure and to determine whether p53 protein can serve as a biomarker for this exposure or not. Methods: Oral squamous cell carcinoma, HeLa, and bone marrow mesenchyme cells were exposed to noncontact electric fields of Electro-Capacitive Cancer Therapy (ECCT) for 24 h. To observe the mechanism of cell death caused by ECCT, immunocytochemistry of p53 was performed, and the p53 expression was evaluated using immunoreactive score (IRS) calculation. Results: Electric field exposure by ECCT increased the percentage of dead cells in oral cancer cells (18.39%), HeLa cells (6.60%), and bone marrow mesenchyme cells (34.05%) with statistical significance using the independent t test compared to each control group. The IRS of p53 in oral cancer, HeLa, and bone marrow mesenchyme cultures were 10.50, 11.25, and 4.94, respectively. Conclusion: The high IRS shown in the treated oral cancer and HeLa culture cells may suggest that p53 expression in these culture cells is associated with the cell death mechanism induced by the exposure to noncontact electric fields, and the increased cell death in these culture cells may correlate with the IRS."
