Figure 4. Sankey plots of signaling pathways and biological processes related to differentially expressed mRNAs in PAAD tissues. Sankey plots show (A) signaling pathways and (B) biological processes (BP) related to DEmRNAs involved in PAAD based on Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment and Gene Ontology_Biological Process (GO_BP) analyses, respectively.
