Thrombin Signaling Promotes Pancreatic Adenocarcinoma through PAR-1–Dependent Immune Evasion

Pancreatic ductal adenocarcinoma (PDAC) is associated with robust activity of the coagulation system. To determine mechanisms by which clotting factors influence PDAC tumor progression, we generated and characterized C57Bl/6-derived KPC (KRasG12D, TRP53R172H) cell lines. Tissue factor (TF) and protease-activated receptor-1 (PAR-1) were highly expressed in primary KPC pancreatic lesions and KPC cell lines similar to expression profiles observed...
