Electromagnetic fields act via activation of voltage-gated calcium channels to produce beneficial or adverse effects

AI: Melanie Research RF Safe Research Library Jan 1, 2013 CONCERN LOW

This narrative review argues that non-thermal biological effects of extremely low and microwave frequency EMFs may be mediated by activation of voltage-gated calcium channels (VGCCs). It cites 23 studies in which VGCC blockers reportedly block or reduce diverse EMF effects and proposes downstream Ca2+/calmodulin-dependent nitric oxide signaling. The review discusses both potential therapeutic effects (e.g., bone growth stimulation) and potential adverse effects via oxidative stress pathways, including a reviewed example of DNA single-strand breaks.

Key points

The article is a narrative review focused on mechanisms of non-thermal EMF effects.
It reports that 23 studies support VGCC involvement because VGCC blockers reduce or block EMF-related effects.
The review proposes that VGCC voltage-gated properties provide a plausible biophysical basis for EMF interactions.
Downstream signaling is proposed to involve Ca2+/calmodulin stimulation of nitric oxide synthesis.
Potential therapeutic effects are linked to an NO–cGMP–protein kinase G pathway, with bone growth stimulation discussed as an example.
Potential adverse effects are linked to an NO–peroxynitrite–oxidative stress pathway, including a reviewed example of DNA single-strand breaks measured by comet assay.
The abstract notes that mechanistic data for EMF-induced DNA single-strand breaks are limited.
