Electroporation in Cancer Therapy: A Simplified Model Derived from the Hodgkin-Huxley Model

Area of Science:

• Biomedical Engineering
• Oncology
• Computational Biology

Background:

• Cancer poses a significant global health burden, with conventional treatments like chemotherapy and surgery presenting limitations and side effects.
• Pulsed electric fields and electroporation offer promising alternatives for cancer treatment, potentially reducing adverse effects.
• Developing accurate and accessible models for electroporation is crucial for advancing its therapeutic applications.

Purpose of the Study:

• To provide a comprehensive overview of electroporation as an innovative cancer therapy tool.
• To introduce a simplified reversible electroporation model based on the Hodgkin-Huxley model.
• To facilitate easier modeling and implementation of reversible electroporation dynamics for cancer research.

Main Methods:

• A comprehensive review of electroporation principles, pulse generators, and delivery devices in cancer therapy.
• Development of a simplified reversible electroporation model derived from the Hodgkin-Huxley framework.
• Simulation of ionic current regulation and pore dynamics based on transmembrane potential thresholds.

Main Results:

• The proposed model maintains resting potential stability through ionic current regulation.
• The model accurately simulates rapid pore opening and increased current upon reaching the electroporation threshold.
• The model demonstrates gradual pore resealing and current decline as the transmembrane potential decreases.

Conclusions:

• The simplified electroporation model offers a valuable tool for understanding and implementing reversible electroporation dynamics.
• This model can aid in the further exploration and optimization of electroporation-based cancer therapies.
• Electroporation presents a promising avenue for developing more effective cancer treatments with potentially fewer side effects.
