Research

Pancreatic ductal adenocarcinoma (PDAC) is the most lethal solid malignancy with a 5 year survival rate of 8%. Most patients are diagnosed at metastatic stages and treatments are largely ineffective. The refractory nature of PDAC has been attributed to its characteristic tumor microenvironment (TME) which comprises 70-80% of tumor mass. The TME is composed of an abundance of immunosuppressive myeloid cells and cancer-associated fibroblasts (CAFs) in a dense fibrotic matrix. Recent single cell transcriptomic studies have identified phenotypically heterogeneous CAF subsets but their specific functions remain unexplored. My project is focused on determining the role of a senescent CAF subset in PDAC biology and therapeutic resistance.
