Participating investigators include faculty from the departments of Biochemistry, Cancer Biology, Neurobiology and Anatomy, Medicine, Microbiology and Immunology, Pathology, Pediatrics, Physiology and Pharmacology, and Surgery.
The major focus of investigators in this area is the use of genetic and molecular approaches to study the underlying mechanisms of cancer and factors that contribute to tumor progression. Examples include identification of cancer susceptibility genes, genetic variation in tumor formation, DNA damage and repair pathways, and carcinogens.
Focus of the identification of molecular markers/targets that are specific to brain tumors. Faculty Profile & Publications
Research in our laboratory is directed towards applying advanced systems biology methodologies to i] investigate the timing of signaling events in the propagation of receptor tyrosine kinases signaling, ii] quantify the effect of oncogenic mutations or oxidation on the re-wiring of these signaling networks under pathogenic conditions, iii] apply clinical proteomics to identify molecular predictors of response to different cancer therapies in an effort to create personalized therapies; and iv] interface time-resolved mass spectrometry with microfluidics technology and develop new nanokinetics platforms for quantitative monitoring of rapid enzyme kinetics/drug screening assays to further our understanding of potential drug targets at molecular level.
