950 MHz UHF EMR did not cause oxidative stress in neonates or 6- and 15-day-old rats but altered polyunsaturated fatty acid levels in neonates and was genotoxic in 30-day-old rats.

Plain English Summary

Summary written for general audiences

Researchers assessed the effect of 950 MHz ultra-high-frequency electromagnetic radiation on biomarkers of oxidative damage, unsaturated fatty acid concentrations, and catalase expression in the livers of rats of different ages. Twelve rats per age group were divided into control and exposed groups and exposed for half an hour per day for up to 51 days at a specific absorption rate of 1.3–1.0 W/kg. The radiation did not cause oxidative stress and was not genotoxic in neonates or 6- and 15-day-old rats, but it changed polyunsaturated fatty acid concentrations in neonates. In 30-day-old rats there was no oxidative stress but the radiation was genotoxic to the livers of exposed rats.

Why This Matters

Protein carbonyl accumulation did not differ across ages. Exposed neonates also exhibited lower catalase expression.

Study Details

To assess the effect of 950 MHz ultra-high-frequency electromagnetic radiation (UHF EMR) on biomarkers of oxidative damage, as well as to verify the concentration of unsaturated fatty acids (UFA) and the expression of the catalase in the livers of rats of different ages

Twelve rats were equally divided into two groups as controls (CR) and exposed (ER), for each age (0,...

The neonates had low levels of TBARS and concentrations of UFA after exposure. There was no age diff...

950 MHz UHF EMR does not cause oxidative stress (OS), and it is not genotoxic to the livers of neonates or those of 6 and 15 day old rats, but it changes the concentrations of polyunsaturated fatty acid (PUFA) in neonates. For rats of 30 days, no OS, but it is genotoxic to the livers of ER to total body irradiation.

Quick Questions About This Study

Lipid damage was measured by TBARS, protein damage by protein carbonyls, DNA damage by comet assay, unsaturated fatty acids by gas chromatography, and catalase expression by Western blotting.
Neonates had low levels of TBARS and unsaturated fatty acid concentrations after exposure, and exposed neonates exhibited lower catalase expression.
For 30-day-old rats there was no oxidative stress but the radiation was genotoxic to the livers of exposed rats.
The study concluded that 950 MHz UHF EMR does not cause oxidative stress in neonates, 6-day-old, 15-day-old, or 30-day-old rats.
