The overall theme of the CTPR is to study how pediatric diseases develop from systems biology and mechanistic standpoints with the ultimate goal of identifying points in the intersection of disease and development which, in turn, will produce targets for intervention and the development of new treatments. The Proteomics Core provides a crucial piece of the systems biology puzzle - the large-scale identification and quantification of proteins and protein posttranslational modifications.
