1. Protective roles of single-wall carbon nanotubes in ultrasonication-induced DNA base damage
Published: 8/27/2012
Authors: Elijah J Petersen, Xiaomin X. Tu, M Miral Dizdar, Ming Zheng, Bryant C Nelson
Abstract: Ultrasonication is a physical process known to generate abundant levels of oxygen-derived species such as hydroxyl radicals, hydrogen atoms, and hydrogen peroxide. Highly reactive hydroxyl radicals can react with DNA to generate strand breaks and a m ...

2. Tools and Approaches for the Assessment of Nanomaterial Induced Oxidative DNA Damage
Published: 6/20/2012
Authors: Elijah J Petersen, Bryce J. Marquis, Pawel Jaruga, M Miral Dizdar, Bryant C Nelson
Abstract: 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 r ...

3. Pro-oxidant Induced DNA Damage in Human Lymphoblastoid Cells: Homeostatic Mechanisms of Genotoxic Tolerance
Published: 4/26/2012
Authors: Bryant C Nelson, Bryce J. Marquis, Anna L Seager, Ume Kulsoom Shah, Jane M Mikhail, Shareen H Doak, George E Johnson, Paul L Carmichael, Sharon J Scott, Andrew D Scott, Gareth JS Jenkins
Abstract: Oxidative stress contributes to many disease aetiologies including ageing, neurodegeneration, and cancer, partly through DNA damage induction (genotoxicity). Understanding the interactions of free radicals with DNA is fundamental to discern the mutat ...

6. Stable isotope-labeling of DNA repair proteins, and their purification and characterization
Published: 7/1/2011
Authors: M Miral Dizdar, Pawel Jaruga, Prasad T Reddy, Bryant C Nelson, Mark S Lowenthal
Abstract: 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 cance ...

9. Mechanisms and Measurement of Nanomaterial-Induced Oxidative Damage to DNA
Published: 6/22/2010
Authors: Bryant C Nelson, Elijah J Petersen
Abstract: Many of the current investigations on the environmental health and human safety risks of engineered nanomaterials focus on their short-term acute effects. However, the long-term chronic effects of nanomaterials on living systems, and in particular, ...
