Structural and biochemical studies of a plant formamidopyrimidine-DNA glycosylase reveal why eukaryotic Fpg glycosylases do not excise 8-oxoguanine.

M Miral Dizdar, Pawel Jaruga, Susan Duclos, Pierre Aller, Susan Wallace, Susan Doublie
Formamidopyrimidine-DNA glycosylase (Fpg; MutM) is a DNA repair enzyme widely distributed in bacteria. Fpg recognizes and excises oxidatively modified purines, 4,6-diamino-5-formamidopyrimidine, 2,6-diamino-4-hydroxy-5-formamidopyrimidine and 8-oxoguanine

Tools and Approaches for the Assessment of Nanomaterial Induced Oxidative DNA Damage

June 20, 2012
Author(s)
Elijah J. Petersen, Bryce J. Marquis, Pawel Jaruga, M Miral Dizdar, Bryant C. Nelson
Hyphenated mass spectrometry techniques have been employed as one of the primary analytical tools for investigating the effects of ionizing radiation, chemical/biological carcinogens, and oxygen derived free radicals on the induction and subsequent repair

Identification and quantification of DNA repair proteins by liquid chromatography/isotope-dilution tandem mass spectrometry using 15N-labeled whole proteins as internal standards

May 30, 2012
Author(s)
M Miral Dizdar, Prasad T. Reddy, Guldal Kirkali, Gamze Tuna, Bryant C. Nelson, Pawel Jaruga
Oxidatively induced DNA damage is implicated in disease, unless it is repaired by DNA repair. DNA repair proteins may be used as early detection and therapeutic biomarkers in cancer and other diseases. For this purpose, the measurement of the expression

Mechanisms of free radical-induced damage to DNA

April 1, 2012
Author(s)
M Miral Dizdar, Pawel Jaruga
Endogenous and exogenous sources cause free radical-induced DNA damage in living organisms by a variety of mechanisms. The highly reactive hydroxyl radical reacts with the heterocyclic DNA bases and the sugar moiety near or at diffusion-controlled rates by

Oxidatively Induced DNA Damage and Cancer

December 30, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga
Oxidatively induced DNA damage is caused by endogenous and exogenous sources in living organisms. Many resulting DNA lesions are mutagenic and lead to mutations commonly found in cancer. Repairs mechanisms exist to repair this type of DNA damage

Copper oxide nanoparticle mediated DNA damage in terrestrial plant models

December 22, 2011
Author(s)
Bryant C. Nelson, Donald H. Atha, Elijah J. Petersen, Huanhua Wang, Danielle Cleveland, Richard D. Holbrook, Pawel Jaruga, M Miral Dizdar, Baoshan Xing
Engineered nanoparticles, due to their unique electrical, mechanical and catalytic properties, are presently found in many commercial products and will be intentionally or inadvertently released at increasing concentrations into the natural environment

Evidence for upregulated repair of oxidatively induced DNA damage in human colorectal cancer

September 15, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga, Prasad T. Reddy, Guldal Kirkali, Didem Keles, Gulgun Oktay, Aras E. Canda
Molecular pathways that play a role in the development of colorectal cancer involve multiple genetic changes in cancer-related genes that may be caused by overproduction of oxygen-derived species including free radicals, which are capable of damaging DNA

Stable isotope-labeling of DNA repair proteins, and their purification and characterization

July 1, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga, Prasad T. Reddy, Bryant C. Nelson, Mark S. Lowenthal
Reduced DNA repair capacity is associated with increased risk for a variety of disease processes including carcinogenesis. Thus, DNA repair proteins have the potential to be used as important predictive, prognostic and therapeutic biomarkers in cancer and

A Major Role for Non-Enzymatic Antioxidant Processes in the Radioresistance of Halobacterium salinarum

April 1, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga, Courtney K. Robinson, Kim Webb, Amardeep Kaur, Nitin S. Baliga, Allen Place, Jocelyne DiRuggiero
Oxidative stress occurs when the generation of reactive oxygen species (ROS) exceeds the capacity of the cell’s endogenous systems to neutralize them. We analyzed the oxidative stress responses and cellular damage of the archaeon Halobacterium salinarum
