Research Interests

The hypothesis for this study is that differentially expressed nitroproteins (DENPÖs) exist between human pituitary controls and adenomas. We base our hypothesis on our recent discovery of sixteen 3-nitrotyrosine-containing proteins (3NT proteins; nitroproteins) and several nitroprotein:protein complexes in human pituitaries. Biomarker DENPÖs provide a window into oxidative stress, reactive nitrogen species (RNS), reactive oxygen species (ROS), free radicals, and tumorigenesis. We focus on brain tumors, and specifically on pituitary adenomas. The molecular mechanisms that participate in the formation of non-secreting macroadenomas are largely unknown; more is known about hormone-secreting microadenomas.

Although reversible and non-reversible protein modifications occur, we focus on a chemically stable end-product biomarker, 3-nitro tyrosine (3NT). We analyze nitroproteins in human pituitary tissues (post-mortem controls; post-surgical adenomas) to identify DENPÖs. Those biomarker DENPÖs will clarify molecular events that occur in brain tumors and pituitary adenomas. Those results are readily translatable to other cancer studies.

We have extensive preliminary data on human pituitaries from collaborations with our neurosurgeon colleagues J. T. Robertson, M.D. (University of Tennessee) and Nelson M. Oyesiku, M.D. (Emory University). We have published the quantitation of neuropeptides (controls; adenomas), comparative proteomics to discover differentially expressed proteins (DEPÖs), qualitative phosphoproteomics to discover phosphoproteins, and qualitative nitroproteomics to discover nitroproteins. We have compared our DEPÖs with differential genes.
