About Dr. Millward
Directed Evolution of Imaging Agents. The ideal molecular imaging agent would have the affinity and target specificity of monoclonal antibodies along with the rapid systemic clearance of small molecules. While peptides have shown promise as in vitro imaging probes, their short half-life, poor stability, and low affinity have traditionally made them unsuitable for in vivo applications. They are using mRNA display in conjunction with chemical modification to select for high-affinity, modification-resistant peptides in ex vivo and in vivo systems.
Visualizing Autophagy in Living Systems. Autophagy is a highly conserved catabolic process where cellular components are engulfed and degraded to provide energy in times of metabolic stress. Autophagy has been shown to play both a pro-tumor and anti-tumor role in cancer. While the molecular mechanisms of autophagy are beginning to be understood, there is no easy way to unambiguously image autophagy in living cells and tissues or to determine the extent of autophagic flux. They are using a chemical biology, metabolomics, and directed evolution strategies to visualize this and other related forms of cell death in models of ovarian cancer

Molecular Imaging has enormous potential to qualitatively change the way cancer is understood, diagnosed, and treated. The advancement of this field depends greatly on the development of new imaging probes that report the biological activity of cancer-relevant proteins in addition to their absolute concentration in the tumor cell. The peptide-based caspase activity probes described in this proposal represent a new and powerful approach to this problem that can guide cancer treatment in real time. I have worked in the field of peptide discovery, chemistry, and characterization for over ten years; as a graduate student with Prof. Rich Roberts (Caltech) and as a postdoc with Prof. James Heath (Caltech). I have over ten years of experience in peptide synthesis, synthetic organic chemistry, biochemistry, and cell biology. The focus of my graduate work in the laboratory of Prof. Rich Roberts was the incorporation of unnatural amino acids to increase the proteolytic stability and drug-like properties of mRNA display libraries.
My innovations in this area make me especially suited to develop tetrazole-containing unnatural amino acids to increase the cell permeability and bio-stability of caspase imaging probes. During my postdoctoral work at the NanoSystems Biology Cancer Center (Caltech), I employed in situ click chemistry to design novel branched peptide architectures which were used to image Akt activation in ovarian cancer cells. This work has provided me with extensive experience in azide-based click chemistry making me well-suited to rapidly carry out the tetrazole syntheses described in the proposal. My appointment as an Assistant Professor in the Department of Cancer Systems Imaging at The University of Texas M.D. Anderson Cancer Center will enable me to translate fluorescence-based caspase probes into optical and PET imaging agents for pre-clinical development.
