These observations were confirmed in PAAD tumors, with significantly higher infiltration levels of fibroblasts (p = 0.02017 FDR), cells of the monocytic lineage (p = 0.0162 FDR), and endothelial cells (p = 7.33 ×10−4 FDR) in tumors with high GR activity score/SERPINE1 (Figure S6). The gene discussed is SERPINE1; the disease is pancreatic adenocarcinoma.
