Research Interests
My group's major research interest is
the study of the chemical and molecular mechanisms of antitumor agents. We apply
a variety of techniques and approaches to these studies, including
computational chemistry (2D- and 3D-QSAR, macromolecular modeling), synthetic
chemistry (design and preparation of novel agents, their radio- and stable
isotope-labeled forms, photoaffinity probes), analytical chemistry (GC- and
LC-MS, NMR), metabolism studies (microsomal and cells in culture),
bioanalytical methods, and the use of human carcinoma cells and normal human
epithelial cells in culture. One of our major interests is agents that target
microtubules. Lead compounds are the microtubule stabilizers (+)-discodermolide
and (-)-dictyostatin (E. Hamel, D.P. Curran, J.L. Eiseman, A. Vogt), and the
tubulin assembly inhibitors pironetin and the tubulysins (S.G. Nelson, P. Wipf,
A. Vogt). Other molecular targets for which we are pursuing small molecule
inhibitors and more mechanistic information include the molecular motor dynein
(D.P. Curran, P. Wipf, K. Brummond, D. DeFranco, R.B. Vallee, P.A. Johnston),
the estrogen receptors (P. Wipf, M. Nichols, W. Xie), chaperone proteins (P.
Wipf, J.L. Brodsky), dual specificity phosphatases (M. Tsang, J.S. Lazo, A.
Vogt), p53/MDMx interactions (A. Doemling), HIV-1 protein/host protein interactions (T.E. Smithgall) and topoisomerase II (J.C. Yalowich,
V.E. Kagan, B. Hasinoff).
We also have a major interest in the molecular
dosimetry of carcinogens. We are particularly interested in defining the
chemistry of protein adducts made by the electrophilic forms of these agents.
Ongoing projects in this area include one aimed at determining the relative
contributions of reactive nitrogen and oxygen species in cell injury (V.E.
Kagan, J.C. Yalowich, N. Gorbunov, J. Atkins, M.P. Fink). We have developed
isotope dilution GC- and LC-MS methods for quantitation of protein alterations,
and have studied the interactions of nitric oxide with hemoproteins by ESR and
LC-MS. The second is use of isotope dilution MS methods for quantitation of
protein adducts of metabolically activated aromatic amines.
We provide the home for the Proteomics
Core Lab of the Schools of the Health Sciences. Ongoing proteomics projects in
the Day lab include a study of nuclear matrix proteins in normal vs. cancerous
breast (J.J. Latimer, S.G. Grant) and the influence of altered levels of
stathmin on microtubule stabilizer sensitivity (M.A. Jordan). Difference 2D
gels, solution-phase isoelectric focusing, MALDI-TOF-MS, MALDI-TOF/TOF-MS/MS,
micro- and nano-MDLC separations for LC-MALDI, LC-ESI-TOF-MS, MDLC-ESI-ion
trap-MS^n, LC-ESI-QqTOF-MS/MS and LC-ESI/MALDI-hQh-ICR FT-MS analyses are
available on a cost-recovery or collaborative basis (cƒ. core labs website)
