MESSERSMITH RESEARCH LAB
RESEARCH FOCUS
Dr. Messersmith’s lab is mainly focused on using a personalized approach in developing new anticancer drugs for GI cancers. In particular, the lab uses a novel colorectal and pancreatic explant model whereby tumor tissue is obtained from the operating room and then placed directly into mice. Tumors are treated with new drugs and predictive biomarkers of sensitivity are discovered. These predictive markers are used in the clinic to pre-select patients that would most likely derive benefit from these new drugs. Additionally, these tumors are evaluated in orthotopic and metastatic models. Current anticancer drugs in the lab target Notch (g-secretase), Src, and hedgehog pathways.
