Johann, Jr. NCI-FDA Clinical Proteomics Project, NIH Tuesday, September 30, 2003 4:30 pm Verizon Auditorium, Prince William Campus, Building PW1 The cause of most human disease is due to the dysfunction of protein networks. Although cancer is classified as a genetic disease, it is a function of a proteomic disease. Gene mutations result in aberrant protein activity within the cell, the cellular microenvironment, and the serum. Proteins dictate biological processes, and determine cellular fates. Changes in key signaling pathways can result in selected cellular survival advantages. Through the study of key signaling pathways a wiring diagram of the cell and itUs microenvironment can be constructed. The true scientific goal of proteomics is the characterization of information flow within the cell and eventually an organism. Information flow is determined and controlled via protein pathways and networks. Visualization and data mining computational tools are a major component of the platform proteomic technologies under development at the NCI-FDA Clinical Proteomics Project. Specific techniques include aggregating viewers for large multi-dimensional datasets, hybrid classifiers involving genetic algorithms and clustering, decision trees, decision tables, and Bayesian methods. A major goal is the establishment of a software framework to allow learning from this new data source. Ultimate project goals are aimed at early detection of disease, choosing and judging efficacy of therapy, and detecting early signs of toxicity. Visualization and data mining techniques are focused at both serum and tissue proteomic methods. ---------------------------------------------------------------------- Refreshments are served at 3:30pm.
