    <description descriptionType="Abstract">Ischemia-reperfusion (I/R) injury, by inducing oxidative DNA damage, is one of the leading causes of increased patient morbidity and mortality in coronary artery by-pass grafting (CABG) surgery. 8-Hydroxyguanine (8-OHG) is an important oxidative base lesion. The 8-oxoguanine glycosylase (hOGG1) and hMTH1, which have several polymorphisms, remove 8-OHdG from the nucleotide pool. We investigated whether there are any correlations the biomarkers of oxidative stress (superoxide dismutase; SOD and 8-OHdG in serum) with genotype for two DNA repair genes (OGG1 and MTH1) and an antioxidant enzyme gene (manganese superoxide dismutase; MnSOD). Therefore, we measured DNA damage (8-hydroxy-2-deoxyguanosine; 8-OHdG) and endogenous antioxidant activity (SOD) at five different time points (T1, before anesthesia; T2, after anesthesia; T3, after ischemia; T4, after reperfusion and T5, after surgery). and also, MnSOD and MutT homolog 1 (MTH1) genes polymorphisms were genotyped by polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) in patients undergoing coronary artery by-pass grafting (CABG) surgery. No statistically significant differences were detected in the levels of 8-OHdG and SOD in serum in terms of OGG1 Ser326Cys, MTH1 Val83Met and MnSOD Ala16Val genetic polymorphisms. Our results suggest that OGG1, MTH1 and MnSOD gene polymorphisms are not genetic risk factors for I/R injury.</description>
