Fig 1: The boxplots and scatter plots of CTLA4 (A) and PDCD1 (B) in the low-and high-risk groups. (C) Boxplots showing estimated IC50 values for Olaparib, Niraparib, Berzosertib, AZD6738 and MK8776 in the TCGA-PAAD dataset (D) The uniform manifold approximation and projection (UMAP) plot demonstrates main cell types in PAAD. (E) The distribution of each type and DDR-based score expression in PAAD. (F) DDR-based scores in different cells are various (p < 0.05). (G) Staining scores of MET and ERAP2 were graded at four levels and two groups. Scale bar, 100 μm. (H) The OS of patients in the high and low expression of MET or ERAP2.
