We then mapped these microRNA targets to KEGG pathways, and found that 5(2), 12(6), 10(4), 14(12), 4(5) and 1(3) targets of mir-30b(mir-30d) belonged to the pathways of “type II diabetes (04930)”, “Type I diabetes (04940)”, “pancreatic cancer (05212)”, “insulin signaling (04910)”, “PPAR signaling (03320)” and “maturity onset diabetes of the young (04950)”, respectively (Table 4). This evidence concerns the gene INS and pancreatic neoplasm.
