My laboratory and clinical research focus on understanding genomics and signaling in colorectal cancer to develop new treatments for patients. Colorectal tumors are characterized by a high level of baseline receptor tyrosine kinase (RTK) signaling. Oncogenic inhibition of these tumors, for example with RAS or BRAF inhibitors, releases these receptors from negative feedback suppression and attenuates response to treatment. Combination treatment is thus needed, however, resistance often develops rapidly. Resistance alterations recurrently include gene amplifications that function to increase signaling from upstream RTKs despite presence of drug. Our lab uses cell lines, patient derived xenograft and organoid models, and clinical samples to evaluate tumor signaling and effects of drug inhibition. We are also analyzing the underlying processes driving resistance and investigating the role of chromosomal instability as an enabler of rapid resistance. Using novel agents and genomic techniques, we are testing the potential of inhibiting DNA repair pathways to prevent the emergence of resistance and prolong therapeutic responses.
