Protective Effect of 10-Hz, 1-mT Electromagnetic Field Exposure Against Hypoxia/Reoxygenation Injury in HK-2 Cells

Biomed Environ Sci. 2015 Mar;28(3):231-4. doi: 10.3967/bes2015.032.

Abstract

We investigated the protective effects of electromagnetic field (EMF) on the survival of the human renal proximal tubular cell line, HK-2, using an in vitro hypoxia/reoxygenation (H/R) injury model. The survival rate of cells cultured under H/R condition declined significantly, while the intracellular reactive oxygen species (ROS) levels markedly increased. The 10 Hz/1 mT EMF exposure reversed the H/R induced reduction in cell survival and induction of intracellular ROS. Our results suggest that 10 Hz/1 mT EMF exposure could inhibit H/R-induced cell death of HK-2 via suppression of intracellular ROS production and that this treatment might be clinically useful for the amelioration of renal ischemia/reperfusion injury.
