DEGs identified from the batched GEO datasets with the Venn diagrams. A The hierarchical cluster heatmaps of DEGs between PDA and normal pancreas from the four GEO batched datasets. The gradual change from red to green represents changes in gene expression from high to low. The black color indicates no difference in gene expression. B The intersection among “Pancreas > Lymph Nodes”, “Pancreas > DLBCL” and “PDA > Pancreas” groups. C The intersection among “Pancreas < Lymph Nodes”, “Pancreas < DLBCL” and “PDA < Pancreas” groups.
