Gene therapy breakthrough: Scientists use electromagnetic fields to switch genes on and off

A groundbreaking gene-switching technology developed by scientists at Dongguk University in Seoul offers a revolutionary approach to gene therapy, allowing for the remote and reversible control of gene activity using electromagnetic fields (EMF).

Traditional gene therapy often involves irreversible interventions, leaving doctors with limited options if adverse side effects arise. This new system, detailed in the journal 'Cell,' acts as an "on-off" switch for genes. Researchers, led by Prof. Jongpil Kim and Yerim Hwang, demonstrated that by applying EMFs, they could precisely regulate the activity of specific genes, such as Lgr4, which plays a crucial role in tissue development and stem cell function.

The system's effectiveness was shown in modified mice, where gene expression could be activated in targeted organs upon EMF exposure and return to baseline levels within 24 hours after the field was deactivated. A key aspect of this discovery is the identification of Cyb5b protein as a potential molecular sensor for EMFs, enabling a precise biological code of ionic oscillations rather than a simple calcium concentration increase.

This innovation holds significant promise for treating complex diseases. Preclinical trials have explored its potential in models of Alzheimer's disease and depression. By cyclically exposing older rodents to EMFs and controlling genes like Tph2, researchers were able to partially reprogram cells and restore normal function, offering new hope for conditions that have long challenged medical science.
