The KEGG pathway analysis of significantly deregulated miRNAs showed the involvement of different numbers of miRNAs in various biological pathways, including FOXO signaling, Huntington’s disease, HIF-1 signaling pathway, P53 signaling, adherens junction, Wnt signaling pathway, Hippo signaling, cell cycle, RNA degradation, p53 signaling pathway, RNA degradation, stress-activated MAPK cascade, and cell death (Figure 9F). The gene discussed is TP53; the disease is juvenile Huntington disease.
