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 PPARA and type 1 diabetes mellitus.
