Resveratrol administration prevents radiation-related changes in metabolic profiles of hearts 20 weeks after irradiation of mice with a single 2 Gy dose.

We aimed to evaluate whether resveratrol affects radiation-induced changes in metabolite profiles of the mouse heart. Hearts were irradiated in vivo with a single 2 Gy dose during the resveratrol administration and metabolite profiles of heart tissue were analyzed by the untargeted HR-MAS NMR approach twenty weeks after irradiation. The administration of resveratrol mitigated the radiation-induced decline in the content of choline-containing compounds and unsaturated lipids, which might reflect the stabilization of cell membrane structure against radiation-related damage. Results obtained with this mouse model suggest that the resveratrol supplementation may prevent metabolic changes related to radiation-induced damage in the heart.
