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

MEASUREMENT OF DNA REPAIR PROTEINS IN RELATION TO DISEASE BIOMARKERS AND DRUG DEVELOPMENT

November 7, 2015
Author(s)
Erdem Coskun, Pawel Jaruga, Leona D. Scanlan, Alessandro Tona, Mark S. Lowenthal, Prasad T. Reddy, M Miral Dizdar, Ann-Sofie Jemth, Olga Loseva, Thomas Helleday
Introduction: In aerobic organisms, intracellular metabolism and exogenous sources such as ionizing radiation and carcinogenic compounds generate reactive species including free radicals derived from either oxygen or nitrogen. Oxidative stress thereby

Extreme Expressions of DNA Repair Proteins APE1 and MTH1, in Human Breast Cancer as Measured by Liquid Chromatography and Isotope Dilution Tandem Mass Spectrometry

September 15, 2015
Author(s)
Erdem Coskun, Pawel Jaruga, Leona D. Scanlan, Alessandro Tona, Mark S. Lowenthal, Prasad T. Reddy, M Miral Dizdar, Ann-Sofie Jemth, Olga Loseva, Thomas Helleday
Accurate measurement of DNA repair proteins in cancer tissues is becoming more important due to the individual and origin based expression differences in cancer patients as well as the novel approach of using the repair enzyme inhibitors in cancer

Addiction to MTH1 protein results in intense expression in human breast cancer tissue as measured by liquid chromatography-isotope-dilution tandem mass spectrometry

June 23, 2015
Author(s)
Erdem Coskun, Pawel Jaruga, Ann-Sofie Jemth, Olga Loseva, Leona D. Scanlan, Alessandro Tona, Mark S. Lowenthal, Thomas Helleday, M Miral Dizdar
MTH1 protein sanitizes the nucleotide pool so that modified 2'-deoxynucleoside triphosphates (dNTPs) cannot be used in DNA replication. Cancer cells require MTH1 to avoid incorporation of modified dNTPs resulting in DNA damage mutations and cell death

High Resolution Surface Plasmon Resonance Imaging for Single Cells

December 1, 2014
Author(s)
Alexander W. Peterson, Michael W. Halter, Alessandro Tona, Anne L. Plant
Background Surface plasmon resonance imaging (SPRI) is a label-free technique that can image refractive index changes at an interface. We have previously shown that SPRI can be used to study the dynamics of cell-substratum interactions. However

Identification and Quantification of DNA Repair Protein Apurinic/Apyrimidinic Endonuclease 1 (APE1) in Human Cells by Liquid Chromatography/Isotope-Dilution Tandem Mass Spectrometry

July 29, 2013
Author(s)
Guldal Kirkali, Pawel Jaruga, Prasad T. Reddy, Alessandro Tona, Li Mengxia, David M. Wison III, M Miral Dizdar, Bryant C. Nelson
Unless repaired, DNA damage can drive mutagenesis or cell death. DNA repair proteins may therefore be used as biomarkers in disease detection or therapeutic response estimation. Thus, the accurate measurement of DNA repair protein expression is of
