My research focuses on identifying and characterizing novel cellular targets for cancer therapy by Systems Biology approach. Cancer systems biology demonstrates that multiple genomic aberrations in cancer cells integrate at the protein level to alter cellular functions. For the past years, I have spent my major efforts to develop and validate the technology of Reverse Phase Protein Arrays (RPPA) in its application of cancer systems biology. RPPA provides robust information to integrate the consequence of genetic aberrations in cancer, to validate therapeutic targets, to demonstrate on- and off-target activity of drugs and to evaluate drug pharmacodynamics. It also characterizes, across large numbers of samples or cell lines, the basal protein expression levels, growth factor- or ligand-induced effects and time resolved responses appropriate for systems biology analysis. To better understand cancer pathobiology, we have joined TCGA program and characterized signaling networks in 3649 cancer samples across different diseases. In addition, we have completed screenings by RPPA with (a) 779 siRNAs targeting protein and lipid kinases; (b) 879 human genome miRNAs; and (c) multiple drug libraries in breast and ovarian cancer cells aiming to identify novel cellular targets for cancer therapy. The studies builds up a "fingerprint" of activity from chemical and genetic manipulations that can rapidly identify novel therapeutic targets as well as determine actions of unknown molecules. As a CCSG RPPA Core director, I have demonstrated myself as a leadership in the field to provide M. D. Anderson investigators and the larger research community around the world with our expertise on functional proteomics studies. Further, I have extensive experiences in collaboration with investigators nationwide and we have successfully completed multiple projects, especially on the studies targeting PI3K-AKT pathway in breast and ovarian cancers. In summary, I have prepared myself as a successful and productive cancer researcher with major contribution to the field of targeted cancer therapy by proteomics approach. My expertise and experiences will lead to the completion of the proposed project.
