Research Summary:

Our research focuses on using mass spectrometry (MS) to understand important biological problems, and we are particularly interested in DNA damage induced by reactive oxygen species and covalent modifications of proteins.

Oxidative DNA DamageIn this research area, we employ a plethora of approaches, which include analytical chemistry, synthetic organic chemistry, biochemistry, and molecular biology, to understand the biological implications of oxidative DNA damage at the molecular level. Our emphasis has been placed on the identification, structure elucidation, and quantification of a class of oxidative DNA lesions where two neighboring nucleobases in the same strand are covalently linked. In this respect, we have been able to characterize the structures of a number of novel oxidative intrastrand crosslink lesions by mass spectrometric and NMR spectroscopic methods. In addition, we quantify the amounts of DNA lesions formed from a variety of oxidation conditions by LC-MS/MS with isotope-incorporated standards. Moreover, we characterize the biophysical and biochemical properties of oxidative DNA Lesions, and we are particularly interested in investigating the thermodynamic as well as the in vitro and in vivo mutagenic properties of various oxidative DNA lesions.

Covalent Modifications of Proteins Current projects in this area encompass the post-translational modifications of chromosomal high-mobility group (HMG) proteins, histones, DNA repair enzymes, and methyl-CpG binding proteins. In this respect, we use mass spectrometry for the identification of the sites and types of modifications, and we also examine the biological functions of these modifications. We have in our laboratory a ThermoFinnigan Deca XP ion trap and an IonSpec FT-ICR mass spectrometer. We also have access to an Applied Biosystems Voyager DE-STR MALDI-TOF and a Micromass Global Ultima Q-TOF mass spectrometers in the Analytical Chemistry Instrumentation Facility as well as a Q-STAR XL O-MALDI Q-TOF mass spectrometer in the W. M. Keck Proteomics Laboratory. Students in our lab have the opportunity to gain hands-on experience with various state-of-the-art mass spectrometers. Depending on the nature of individual research project, they are also exposed to synthetic organic chemistry, biochemistry, molecular biology, and molecular modeling.
