We characterized the oxidative stress (OS) status by the levels of reduced/oxidized glutathione (GSH/GSSG), malondialdehyde (MDA) and the mutagenic base 8-oxo-78-dihydro-2-deoxyguanosine (8-oxo-dG) in human gastric carcinoma (HGC) samples and compared the results with normal tissue from the same patients. We also analyzed 8-oxo-dG in peripheral mononuclear cells (PMNC) and urine from healthy control subjects and in affected patients in the basal state and one, three, six, nine and twelve months after tumor resection. The levels of DNA repair enzyme mRNA expression (hOGG1, RAD51, MUYTH and MTH1) were determined in tumor specimens and compared with normal mucosa. Tumor specimens exhibited increased levels of MDA and 8-oxo-dG compared with normal gastric tissue. GSH levels were also increased, while GSSG levels remained stable. DNA repair enzyme mRNA expression was induced in the tumor tissues. Levels of 8-oxo-dG were significantly elevated in both urine and PMNC of gastric cancer patients compared with

There is increasing experimental evidence to indicate that O6-methyldeoxyguanosine (O6-MedG) formation in DNA is a critical cytotoxic event following exposure to certain antitumor alkylating agents and that the DNA repair protein O6-alkylguanine-DNA-alkyltransferase (ATase) can confer resistance to these agents. We recently demonstrated a wide interindividual variation in the depletion and subsequent regeneration of ATase in peripheral blood lymphocytes of patients treated with 24-h continuous infusion of 1-p-carboxyl-3,3-dimethylphenyltriazene (CB10-277) for metastatic melanoma. We have now measured the formation of O6-MedG in the DNA of peripheral leukocytes of nine patients receiving this treatment regimen. This lesion could be detected in DNA within 1 h and a progressive increase in adduct levels occurred during the CB10-277 infusion and for 24 h after completion. Considerable interindividual variation was observed in the peak O6-MedG levels, with values ranging from 3.0 to 23.8 µmol ...

N2 - The mechanistic aspects of the methylation of guanine in DNA initiated by methyl radicals that are derived from the metabolic oxidation of some chemical carcinogens remain poorly understood. In this work, we investigated the kinetics and the formation of methylated guanine products by two methods: (i) the combination of •CH3 radicals and guanine neutral radicals, G(-H)•, and (ii) the direct addition of •CH3 radicals to guanine bases. The simultaneous generation of •CH3 and dG(-H)• radicals was triggered by the competitive oneelectron oxidation of dimethyl sulfoxide (DMSO) and 2-deoxyguanosine (dG) by photochemically generated sulfate radicals in deoxygenated aqueous buffer solutions (pH 7.5). The photolysis of methylcob(III)alamin to form •CH3 radicals was used to investigate the direct addition ...

Objective: To investigate potential mechanisms of oxidative DNA damage in a rat model of type I diabetes and in murine proximal tubular epithelial cells (MCT) and primary culture of rat proximal tubular epithelial cells (RPTE).. Research Design and Methods: Phosphorylation of Akt and tuberin, 8-oxodG levels and OGG1 expression were measured in kidney cortical tissue of control and type I diabetic animals as well as in proximal tubular cells incubated with normal or high glucose.. Results: In the renal cortex of diabetic rats, the increase in Akt phosphorylation is associated with enhanced phosphorylation of tuberin, decreased OGG1 protein expression and 8-oxodG accumulation. Exposure of proximal tubular epithelial cells to high glucose (HG) causes a rapid increase in ROS generation that correlates with the increase in Akt and tuberin phosphorylation. HG also resulted in downregulation of OGG1 protein expression, paralleling its effect on Akt and tuberin. Inhibition of PI-3K/Akt significantly ...

H. pylori infection is an ubiquitous disease, with a prevalence in our area in the adult population of healthy controls of ∼72%, with ∼65% of them harboring infection by more virulent cagA-positive H. pylori strains (25, 26).. Oxidative damage is well documented in chronic gastric inflammatory diseases (7-9, 27). Recent published results showed that mucosal oxidative damage in H. pylori infection is associated with increased inflammatory cell infiltration, enhanced apoptosis, and cell proliferation (28, 29), whereas it has been postulated that the progressive accumulation of oxidative DNA damage in certain genes, such as p53, may contribute to gastric carcinogenesis (30). In particular, oxidative DNA damage, shown by 8OHdG levels, closely correlates with H. pylori infection, particularly when sustained by H. pylori-cagA-positive strains (7-9). Patients with H. pylori-cagA-positive infection develop gastric oxidative DNA damage earlier in life and more extensive gastric mucosal alterations, ...

In this study, WANG Yanlis lab in IBP and collaborators from Netherlands demonstrated that TtAgo can independently generate and selectively load functional DNA guides. They found that the guide-free TtAgo is able to degrade unstable double-stranded DNA (dsDNA) targets, generating short DNA products, which are selectively loaded onto TtAgo and guide subsequent DNA target cleavage. They also showed that TtAgo loads dsDNA molecules with a preference toward a deoxyguanosine on the passenger strand at the position opposite to the 5′ end of the guide strand. This explains why in vivo TtAgo is preferentially loaded with guides with a 5′ end deoxycytidine. ...

Effect of coronary angiography on oxidative DNA damage observed in circulating lymphocytes | AVESİS
Endogenous oxidative DNA damage is caused by multiple endogenous and exogenous factors. It is not completely known whether coronary angiography has an effect on DNA damage. The aim of this study was to investigate whether coronary angiography causes oxidative DNA damage. Fifty-four patients who underwent elective coronary angiography for diagnostic purpose were enrolled to the study. For each subject, the frequency of oxidative DNA damage was analyzed by using the comet assay, which is a sensitive biomarker of DNA damage, before and after diagnostic procedures. A highly significant increase of DNA damage mean score was observed in all patients after the coronary angiography procedure (p < 0.001). No significant associations were found between the change in oxidative DNA damage and dose of contrast media and radiation exposure time. A significant correlation was observed between the change of DNA damage and age, hyperlipidemia, hypertension, smoking, Gensini score index, and vitamin B,2 (r = ...
OXIDATIVE DNA DAMAGE AND REPAIR IN CNS CELLS - Indiana University School of Medicine
The recent observations that both DNA adducts and oxidative base damage are increased in the brains from Alzheimer s and Parkinson s patients and in spinal cord tissue of patients with amyotrophic lateral sclerosis (ALS) support the idea that oxidative DNA damage may contribute to the observed loss of neurons in these neurological disorders (8,9). Therefore, understanding how oxidative DNA damage is repaired (or not) is critical for understanding the pathology underlying these diseases. The overall hypothesis of this proposal is that oxidative stress induced DNA damage in neuronal cell lines leading to cellular malfunction and/or death and DNA repair enzymes are critical for the protection of neurons against oxidative stress. The following specific Aims will address this hypothesis. Specific Aim 1: Functional and biochemical characterization of the repair enzymes Ogg1, NTH, MTH, and MYH in the neuroblastoma cell lines SHSY5Y and Neuro-2A and in primary cultures of hippocampal neurons.

Epidemiological studies have shown an association between alcohol (ethanol) consumption and increased cancer risk. The effect of alcohol consumption on the levels and persistence of N(2)-ethylidene-2-deoxyguanosine (N(2)-ethylidene-dG) formed by acetaldehyde, the oxidative metabolite of ethanol, in human leukocyte DNA was investigated. DNA was isolated from venous blood samples obtained from 30 male non-smoking individuals before consumption of alcohol (0h) and subsequently at 3-5h following the consumption of 150mL of vodka (containing 42% pure ethanol). Additional samples were collected 24h and 48h post-alcohol consumption. The levels of N(2)-ethyl-2-deoxyguanosine (N(2)-ethyl-dG) in the DNA were determined following reduction of N(2)-ethylidene-dG with sodium cyanoborohydride using a liquid chromatography-tandem mass spectrometry selected reaction monitoring method. A slight time-dependent trend showing an increase and decrease in the levels of N(2)-ethyl-dG was observed following ...
Correlations between Oxidative DNA Damage, Oxidative Stress and Coenzyme Q10 in Patients with Coronary Artery Disease [Abstract]
Abstract. The correlation of coronary artery disease (CAD) with pro-oxidant/antioxidant balance and oxidative DNA damage was investigated.. Seventy-seven patients with CAD and 44 healthy individuals as control were included in this study.

Tungsten inert gas (TIG) welding represents one of the most widely used metal joining processes in industry. It has been shown to generate a large majority of particles at the nanoscale and to have low mass emission rates when compared to other types of welding. Despite evidence that TIG fume particles may produce reactive oxygen species (ROS), limited data is available for the time course changes of particle-associated oxidative stress in exposed TIG welders. Twenty non-smoking male welding apprentices were exposed to TIG welding fumes for 60 min under controlled, well-ventilated settings. Exhaled breathe condensate (EBC), blood and urine were collected before exposure, immediately after exposure, 1 h and 3 h post exposure. Volunteers participated in a control day to account for oxidative stress fluctuations due to circadian rhythm. Biological liquids were assessed for total reducing capacity, hydrogen peroxide (H2O2), malondialdehyde (MDA), and 8-hydroxy-2′-deoxyguanosine (8-OHdG) concentrations at

Legere Pharmaceuticals: Oral administration of adenosine is effective for improving metabolic syndrome-related parameters [......
We have demonstrated previously that both acute and chronic oral administration of adenosine have novel functions such as anti-hypertensive effects and improved hyperlipidaemia in stroke-prone spontaneously hypertensive rats (SHRSP) fed a normal diet. The purpose of the present study was to investigate the effect of adenosine administration on metabolic syndrome-related parameters in SHRSP fed a high-fat diet. Six-week-old rats were divided into three groups, and were administered either water (control) or adenosine (10 or 100 mg/l) for 8 weeks. During this period, the rats had free access to a high-fat diet based on AIN-93M. The results showed that hypertension, plasma lipid, NO, insulin, glucose and urinary 8-hydroxy-2-deoxyguanosine levels improved significantly in both adenosine groups. The mRNA expression levels of genes involved in anti-oxidative activity and adenosine receptors were also altered in the adenosine groups. Administration of adenosine also increased plasma adiponectin ...
IJMS | Free Full-Text | Molecular Mechanisms of Acetaldehyde-Mediated Carcinogenesis in Squamous Epithelium
Acetaldehyde is a highly reactive compound that causes various forms of damage to DNA, including DNA adducts, single- and/or double-strand breaks (DSBs), point mutations, sister chromatid exchanges (SCEs), and DNA-DNA cross-links. Among these, DNA adducts such as N2-ethylidene-2′-deoxyguanosine, N2-ethyl-2′-deoxyguanosine, N2-propano-2′-deoxyguanosine, and N2-etheno-2′-deoxyguanosine are central to acetaldehyde-mediated DNA damage because they are associated with the induction of DNA mutations, DNA-DNA cross-links, DSBs, and SCEs. Acetaldehyde is produced endogenously by alcohol metabolism and is catalyzed by aldehyde dehydrogenase 2 (ALDH2). Alcohol consumption increases blood and salivary acetaldehyde levels, especially in individuals with ALDH2 polymorphisms, which are highly associated with the risk of squamous cell carcinomas in the upper aerodigestive tract. Based on extensive epidemiological evidence, the International Agency for Research on Cancer defined acetaldehyde associated with the

Measurement of 8-hydroxyguanine as an oxidative stress biomarker in saliva by HPLC-ECD | Genes and Environment | Full Text
Oxidative stress leads to many kinds of diseases. Currently, urinary 8-hydroxydeoxyguanosine (8-OHdG) is widely measured as an oxidative stress biomarker. There is a specific advantage if saliva can be used as the sample to measure the oxidative stress biomarker, because saliva is much easier to collect than urine. In this study, we investigated the measurement of 8-hydroxyguanine (8-OHGua) as an oxidative stress marker in saliva, by a column switching HPLC system equipped with an electrochemical detector (HPLC-ECD). The 8-OHGua in saliva could be detected as a single peak by HPLC-ECD. The average level of 8-OHGua in saliva was 3.80 ng/mL in ordinary, non-smoking subjects. The salivary 8-OHGua levels of smokers were significantly higher than those of non-smokers. Salivary 8-OHGua may be a useful noninvasive and promising oxidative stress biomarker.

B54 Background: Oxidative reactions have been implicated as important modulators of human health and can play a role in both disease prevention and disease development. A large number of studies have demonstrated an increased oxidant burden and consequently increased markers of oxidative stress in the blood, and urine of patients with chronic obstructive pulmonary disease (COPD).The overall goal of this study is to explore the association between urinary markers of DNA damage as measured by 8-hydroxydeoxyguanosine ( 8-OhDG), antioxidant enzymes, and FEV1/FVC among smokers and former smokers with different levels of pulmonary obstruction. Methods : Cross-sectional analysis of data from baseline samples from participants in an ongoing chemoprevention trial. The study participants provided blood and urine samples which were used for the analysis of 8-OHdG, superoxide dismutase (SOD) and catalase (CAT) levels. All statistical analyses (descriptive & linear regressions) were performed using STATA. ...
