Pancreatic Ductal Adenocarcinoma Stromal Reprogramming Consortium (PSRC)

The PSRC aims to develop a multidisciplinary community of pancreatic ductal adenocarcinoma (PDAC) researchers that will expand upon traditional tumor-centric studies and ongoing immuno-oncology efforts. The network is focusing on the identification, integration, and mechanistic evaluation of additional tumor microenvironment (TME) elements driving PDAC progression and response to therapy.

The intent of this DCB and the NCI Division of Cancer Treatment and Diagnosis program (funded through RFA-CA-21-041/RFA-CA-21-046) is to bridge basic/mechanistic biology with preclinical/translational research. PSRC also aims to adopt a comprehensive “Tumor-TME Co-Organizer” research model in the pursuit of novel biology-backed targets involved in modulating multi-directional tumor-microenvironment dynamics. This expansion is designed to expose new biology-backed vulnerabilities that will inform the design and testing of more effective combinatorial approaches in pre-clinical platforms and near future clinical evaluation.

Publication Highlights

Using single-cell RNA sequencing and patient-derived models, Carpenter et al. with the University of Michigan PSRC Project identified KRT17-high/CXCL8+ intermediary tumor cells with both classical and basal pancreatic cancer subtype features, which regulate myeloid cell infiltration in the pancreatic cancer microenvironment. In a Commentary about the study, Faraoni & McAllister discuss how this discovery “emerges as a promising strategy which may help in pancreatic cancer patients’ stratification and clinical decision making.”

Using tumor explant models, Hasselluhn et al. with the Columbia University PSRC Project identified a key mechanism of angiosuppression (i.e. inhibition of the formation of new blood vessels) in pancreatic cancer, a process that shapes the tumor microenvironment.

Researchers with the PSRC Coordinating Center and the University of Michigan PSRC Project discuss recent advances an challenges in pancreatic cancer research.
