Background: Hyperthyroidism as well as hypothyroidism have been associated with oxidative stress, caused by an imbalance between pro-oxidants and antioxidants. Oxidative stress may damage the genomic apparatus and other cellular structures. Urinary excretion of 8-oxo-7.8-dihydroguanosine (8-oxoGuo) and 8-oxo-7.8-dihydro-2’-deoxyguanosine (8-oxodG), respectively, represent global RNA and DNA oxidation, thus reflecting oxidatively generated modification of nucleic acids in...
