Research summary
Pancreatic ductal adenocarcinoma (PDAC) is traditionally resistant to radiation therapy (RT); however targeted inhibition of oncogenic KRAS signaling and tumor-stromal crosstalk has the potential to make RT a viable therapeutic option and is actively being tested in clinical trials. My thesis work interrogates the mechanism of dual Focal Adhesion Kinase (FAK) and Mitogen-Activated Protein Kinase (MAPK) inhibition in enhancing RT-induced PDAC cell death and long-term tumor control, and how direct versus downstream inhibition of oncogenic KRAS in this setting shapes tumor responses to therapy. Through profiling of cell signaling and DNA damage pathways, survival studies in murine models, and in-depth characterization of patient samples from an active clinical trial using this treatment approach, I hope to better understand how inhibition of these integrated kinase cascades can improve responses to DNA-damaging therapies in PDAC and provide patients with better long-term outcomes.
