Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that differentially expressed genes in the miRNA-mRNA regulatory network were enriched in six pathways: the notch signalling pathway (KEGG:04330), adherens junction (KEGG:04520), p53 signalling pathway (KEG: 04115), pancreatic cancer (KEG: 05212), glycosaminoglycan biosynthesis—heparan sulphate/heparin (KEGG: 00534) and N-glycan biosynthesis (KEGG: 00510); see Table 7. This evidence concerns the gene TP53 and familial pancreatic carcinoma.
