OGG1 DNA Repair Gene Polymorphism As a Biomarker of Oxidative and Genotoxic DNA Damage
Background: Single nucleotide polymorphisms in 8-oxoguanine DNA glycosylase-1 (OGG1) gene modulates DNA repair capacity and functions as one of the first lines of protective mechanisms against 8-hydroxy-2’-deoxyguanosine (8-OHdG) mutagenicity. OGG1-Cys326 gene polymorphism may decrease DNA repair function, causing oxidative stress due to higher oxidative DNA damage. The main purpose of this stu...
متن کاملThe molecular epidemiology of oxidative damage to DNA and cancer.
Oxygen is required for respiration and the energetic processes that enable aerobic life. A cost associated with oxygen use is free-radical formation, which damages genome stability and contributes to various processes including aging, degenerative diseases, and cancer (1,2). Foods including fruits, vegetables, tea components, and trans-fats; nutrients including vitamins C and E, selenium, beta-...
متن کاملDNA repair activity for oxidative damage and risk of lung cancer.
BACKGROUND Although smoking is a major cause of lung cancer, only a proportion of smokers develop lung cancer, suggesting a genetic predisposition in some individuals. Because tobacco smoking is associated with the increased formation of DNA lesions, including those induced from oxidative damage, we investigated whether the activity of the DNA repair enzyme 8-oxoguanine DNA N-glycosylase (OGG),...
متن کاملPancreatic Cancer is Associated with Peripheral Leukocyte Oxidative DNA Damage
Background: DNA damage accumulation has been linked to the cancer phenotype. The purpose of this study was to compare the levels of DNA base 8-hydroxy-2′-deoxyguanosine (8-OHdG) and C-reactive protein (CRP) inflammatory markers in healthy controls and pancreatic cancer patients from a hospital-based case-control study. Materials and Methods: Fifty-five pancreatic cancer patients and 55 healthy ...
متن کاملLipid peroxidation, DNA damage and coenzyme Q10 in lung cancer patients--markers for risk assessment?
OBJECTIVES Early diagnosis and prevention is very important for lung cancer patients. Previous studies have emphasized that the level of coenzyme Q10 (CoQ10), present primarily in mitochondria, decreases with age and is low in patients with chronic diseases. Our goal was to find out if there is any relationship between lung cancer and CoQ10 and lipid peroxidation levels. DESIGN AND METHODS Bl...
