Urinary 8-Oxo-7,8-Dihydro-2'-Deoxyguanosine in Tunisian Electric Steel Foundry Workers Exposed to Polycyclic Aromatic Hydrocarbons.[Pubmed:28355448]

Ann Work Expo Health. 2017 Apr 1;61(3):333-343.

In this study, urinary 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG), as biomarker of oxidative DNA damage, was evaluated in Tunisian electric steel foundry workers and was associated with polycyclic aromatic hydrocarbon (PAH) exposure. Ninety-three healthy male workers were enrolled in the study; 8-oxodG was assessed by liquid chromatography-triple quadrupole mass spectrometry. Exposure to PAHs was evaluated by measuring 16 urinary PAHs (U-PAHs) and 8 monohydroxylated metabolites (OHPAHs). The median 8-oxodG level for all subjects was 3.20 microg l-1 (1.85 microg g-1 creatinine). No correlation between 8-oxodG and 1-hydroxypyrene or any other OHPAH was found. Significant linear correlations between 8-oxodG and some U-PAHs were found, particularly urinary acenaphthylene (r = 0.249), phenanthrene (r = 0.327), anthracene (r = 0.357), fluoranthene (r = 0.248), and pyrene (r = 0.244). Multiple regression analyses confirmed that urinary phenanthrene, anthracene, and naphthalene (the latter with a non-linear relationship) were predictors of 8-oxodG; job title, but not smoking, was a determinant of 8-oxodG; the variance explained by these models was up to 20%. The oxidative DNA damage assessed by urinary 8-oxodG was moderate and in the range of values reported in other occupational fields or in the general population. The results of this study indicate that the investigated biomarkers of PAH exposure were only minor contributors to urinary 8-oxodG.

The anti/syn conformation of 8-oxo-7,8-dihydro-2'-deoxyguanosine is modulated by Bacillus subtilis PolX active site residues His255 and Asn263. Efficient processing of damaged 3'-ends.[Pubmed:28254425]

DNA Repair (Amst). 2017 Apr;52:59-69.

8-oxo-7,8-dihydro-2'-deoxyguanosine (8oxodG) is a major lesion resulting from oxidative stress and found in both DNA and dNTP pools. Such a lesion is usually removed from DNA by the Base Excision Repair (BER), a universally conserved DNA repair pathway. 8oxodG usually adopts the favored and promutagenic syn-conformation at the active site of DNA polymerases, allowing the base to hydrogen bonding with adenine during DNA synthesis. Here, we study the structural determinants that affect the glycosidic torsion-angle of 8oxodGTP at the catalytic active site of the family X DNA polymerase from Bacillus subtilis (PolXBs). We show that, unlike most DNA polymerases, PolXBs exhibits a similar efficiency to stabilize the anti and syn conformation of 8oxodGTP at the catalytic site. Kinetic analyses indicate that at least two conserved residues of the nucleotide binding pocket play opposite roles in the anti/syn conformation selectivity, Asn263 and His255 that favor incorporation of 8oxodGMP opposite dA and dC, respectively. In addition, the presence in PolXBs of Mn(2+)-dependent 3'-phosphatase and 3'-phosphodiesterase activities is also shown. Those activities rely on the catalytic center of the C-terminal Polymerase and Histidinol Phosphatase (PHP) domain of PolXBs and, together with its 3'-5' exonuclease activity allows the enzyme to resume gap-filling after processing of damaged 3' termini.

Preparation and Practical Applications of 2',7'-Dichlorodihydrofluorescein in Redox Assays.[Pubmed:28224799]

Anal Chem. 2017 Apr 4;89(7):3853-3857.

Oxidative stress, a state in which intra- or extracellular oxidant production outweighs the antioxidative capacity, lies at the basis of many diseases. DCFH2-DA (2',7'-dichlorodihydrofluorescein diacetate) is the most widely used fluorogenic probe for the detection of general oxidative stress. However, the use of DCFH2-DA, as many other fluorogenic redox probes, is mainly confined to the detection of intracellular oxidative stress in vitro. To expand the applicability of the probe, an alkaline hydrolysis and solvent extraction procedure was developed to generate high-purity DCFH2 (2',7'-dichlorodihydrofluorescein) from DCFH2-DA using basic laboratory equipment. Next, the utility of DCFH2 was exemplified in a variety of cell-free and in vitro redox assay systems, including oxidant production by transition metals, photodynamic therapy, activated macrophages, and platelets, as well as the antioxidative capacity of different antioxidants. In cells, the concomitant use of DCFH2-DA and DCFH2 enabled the measurement and compartmentalized analysis of intra- and extracellularly produced oxidants, respectively, using a single read-out parameter. Furthermore, hepatocyte-targeted liposomes were developed to deliver the carboxylated derivative, 5(6)-carboxy-DCFH2, to hepatocytes in vivo. Liposome-delivered 5(6)-carboxy-DCFH2 enabled real-time visualization and measurement of hepatocellular oxidant production during liver ischemia-reperfusion. The liposomal 5(6)-carboxy-DCFH2 can be targeted to other tissues where oxidative stress is important, including cancer.
