Enhancing the Efficacy of Cancer Therapy: Use of Small Molecule Inhibitors of DNA Glycosylases as Potential Drugs

March 12, 2017
Author(s)
Erdem Coskun, Aaron C. Jacobs, Nathan Donley, Marcus J. Calkins, Dorjbal Dorjsuren, David Maloney, Anton Simeonov, Pawel Jaruga, Amanda K. McCullough, M Miral Dizdar, R. S. Lloyd
Chemotherapy aims to destroy cancer cells by damaging their DNA. However, the overexpression of DNA repair proteins in cancer cells causes the removal of DNA lesions before they become toxic and thus leads to an increased DNA repair capacity resulting in

Repair of Oxidatively Induced DNA Damage by DNA Glycosylases

February 16, 2017
Author(s)
M Miral Dizdar, Erdem Coskun, Pawel Jaruga
Endogenous and exogenous reactive species cause oxidatively induced DNA damage in living organisms by a variety of mechanisms. As a result, a plethora of mutagenic and/or cytotoxic products are formed in cellular DNA. This type of DNA damage is repaired by

Enhanced Sensitivity of Neil1-/- Mice to Chronic UVB Exposure

December 1, 2016
Author(s)
M Miral Dizdar, Marcus J. Calkins, Vladimir Vartanian, Guldal Kirkali, Amanda K. McCullough, R. S. Lloyd, Pawel Jaruga
DNA base damage induced by oxidative stress and reactive oxygen species (ROS) are thought to be central mediators of ultraviolet light (UV)-induced carcinogenesis and skin aging. However, increased steady-state levels of ROS-induced DNA base damage have

Enhanced Sensitivity of Neil1-/- Mice to Chronic UVB Exposure

October 28, 2016
Author(s)
Pawel Jaruga, M Miral Dizdar, Marcus J. Calkins, Vladimir Vartanian, Amanda McCullough, R. S. Lloyd, Guldal Kirkali
Oxidative stress and oxidatively induced DNA base damage are central mediators of UV-induced carcinogenesis and skin aging. However, increased steady-state levels of oxidatively induced DNA base damage have not been reported after chronic UV exposure

Inhibition of DNA glycosylases in development of cancer therapeutics

September 4, 2016
Author(s)
M Miral Dizdar, Pawel Jaruga, Erdem Coskun, Marcus J. Calkins, Nathan Donley, Dorjbal Dorjsuren, Anton Simeonov, Amanda K. McCullough, R S. Lloyd, Ajit Jadhav
In cancer therapy, the efficacy of therapeutic agents may be influenced by increased DNA repair capacity. This may be due to overexpression of DNA repair proteins that repair therapy-induced DNA lesions in tumors before they become toxic. Inhibition of DNA

Measurement of DNA repair protein apurinic/apyrimidinic endonuclease 1 (APE1) in human tissues by liquid chromatography/tandem mass spectrometry with isotope dilution

June 5, 2016
Author(s)
Pawel Jaruga, Guldal Kirkali, Prasad T. Reddy, Alessandro Tona, Bryant C. Nelson, Li Mengxia, David M. Wilson III, Erdem Coskun, M Miral Dizdar
Introduction DNA repair proteins may be used as biomarkers in disease etiology and therapy. Thus, the accurate determination of DNA repair protein expression and genotype in human tissues is of fundamental importance. Apurinic/apyrimidinic endonuclease 1

Combined Effects of High-Dose Bisphenol A and Oxidizing Agent (KBrO3) on Cellular Microenvironment, Gene Expression, and Chromatin Structure of Ku70-deficient Mouse Embryonic Fibroblasts

April 15, 2016
Author(s)
Erdem Coskun, Pawel Jaruga, Miral M. Dizdar, Natalie Gassman, Samuel Wilson
Background: Exposure to the environmental endocrine disrupting chemical bisphenol A (BPA) has been reported to alter global gene expression, induce epigenetic modifications, and interfere with the complex regulatory networks of cells. In addition to these

Inhibitors of DNA glycosylases as potential therapeutic drugs in cancer

April 4, 2016
Author(s)
M Miral Dizdar, Aaron C. Jacobs, Nathan Donley, Ajit Jadhav, Dorjbal Dorjsuren, David Maloney, Anton Simeonov, Pawel Jaruga, Erdem Coskun, Amanda K. McCullough, R. S. Lloyd
Ionizing radiation and most chemotherapeutic agents kill tumor cells by damaging DNA. The efficacy of DNA-damaging agents may be influenced by increased DNA repair capacity in tumors that results from overexpression of DNA repair proteins. Inhibition of

SMALL MOLECULE INHIBITORS OF DNA GLYCOSYLASES AS POTENTIAL DRUGS IN CHEMO- AND RADIOTHERAPIES

March 19, 2016
Author(s)
M Miral Dizdar, Aaron C. Jacobs, Nathan Donley, Marcus J. Calkins, Ajit Jadhav, Dorjbal Dorjsuren, David Maloney, Anton Simeonov, Amanda K. McCullough, R S. Lloyd, Erdem Coskun, Pawel Jaruga
Introduction: Ionizing radiation and most chemotherapeutic agents kill tumor cells by damag-ing DNA. The efficacy of DNA-damaging agents may be influenced by increased DNA repair capacity in tumors that results from overexpression of DNA repair proteins

GC-MS/MS Measurement of Nanomaterial Induced Genotoxicity in Isolated DNA

November 24, 2015
Author(s)
Bryant C. Nelson, Elijah J. Petersen, Pawel Jaruga, M Miral Dizdar
Making accurate measurements of the environmental fate and environmental and biological effects of engineered nanomaterials (ENMs) is critical for reliable risk assessment of these materials. ENM induced oxidative stress and/or direct binding of ENMs to
