Electromagnetic wireless remote control of mammalian transgene expression
Abstract
Category: Nanotechnology, Biomedical Engineering Tags: electromagnetic fields, transgene expression, wireless control, nanotechnology, ROS, gene therapy, biosensors DOI: 10.1038/s41565-025-01929-w URL: nature.com Overview Communication between wireless field receivers and biological sensors remains a key constraint in the development of wireless electronic devices for minimally invasive medical monitoring and biomedical applications involving gene and cell therapies. Innovation This study describes a nanoparticle-cell interface that enables electromagnetic programming of wireless expression regulation (EMPOWER) of transgenes. This is achieved via the biosafe generation of cellular reactive oxygen species (ROS). - Multiferroic nanoparticles are coated with chitosan to improve biocompatibility. - These nanoparticles generate ROS in the cytoplasm of cells in response to a low-frequency (1-kHz) magnetic field. - Overexpressed ROS-responsive KEAP1/NRF2 biosensors detect the generated ROS and are connected to synthetic ROS-responsive promoters to drive transgene expression. Findings In a proof-of-concept study, subcutaneously implanted alginate-microencapsulated cells stably expressing an EMPOWER-controlled insulin expression system successfully normalized blood-glucose levels in a mouse model of type 1 diabetes in response to a weak magnetic field. Conclusion The research demonstrates a wireless and minimally invasive approach to regulate gene expression in vivo using electromagnetic fields, mediated by biocompatible nanoparticles and ROS-sensitive biosensors. This highlights a direct link between electromagnetic field exposure and physiological regulation at the molecular and cellular level, underscoring the potential health and therapeutic implications of EMF exposure.
