Abstract

Close
- Tens of thousands of people are being exposed daily toenvironmental low-dose gamma radiation. Epidemiological data indicate thatsuch low radiation doses may negatively affect liver function and result in thedevelopment of liver disease. However, the biological mechanisms behindthese adverse effects are unknown. The aim of this study was to investigateradiation-induced damage in the liver after low radiation doses. Neonatal maleNMRI mice were exposed to total body irradiation on postnatal day 10 usingacute single doses ranging from 0.02 to 1.0 Gy. Early (1 day) and late (7months) changes in the liver proteome were tracked using isotope-codedprotein label technology and quantitative mass spectrometry. Our dataindicate that low and moderate radiation doses induce an immediateinhibition of the glycolysis pathway and pyruvate dehydrogenase availability inthe liver. Furthermore, they lead to significant long-term alterations in lipidmetabolism and increased liver inflammation accompanying inactivation of thetranscription factor peroxisome proliferator-activated receptor alpha. This study contributes to the understanding of the potentialrisk of liver damage in populations environmentally exposed to ionizing radiation.
