Abstract
A low-frequency (DC-22.05 kHz), time-varying magnetic field signal (rfe_A1A) was tested against the human-derived SF8628 cell line, a diffuse intrinsic pontine glioma (DIPG). This study was done to determine the efficacy and mechanism of action of the rfe_A1A signal, in vitro and in vivo. In vitro, an acellular tubulin polymerization assay and an SF8628 cell culture assay increased tubulin polymerization rates and reduced cell division, respectively. Mouse survival models of DIPG, subsequently exposed to the rfe_A1A signal, demonstrated significantly longer survival times and biomarker changes in Ki67 expression, consistent with a slowdown in cell-division rates. The rfe_A1A signal significantly increased survival time in a DIPG model, a novel strategy tested in clinical studies and compassionate use cases.
期刊介绍：
Aims & Scope: Electromagnetic Biology and Medicine, publishes peer-reviewed research articles on the biological effects and medical applications of non-ionizing electromagnetic fields (from extremely-low frequency to radiofrequency). Topic examples include in vitro and in vivo studies, epidemiological investigation, mechanism and mode of interaction between non-ionizing electromagnetic fields and biological systems. In addition to publishing original articles, the journal also publishes meeting summaries and reports, and reviews on selected topics.
