FIGURE 1.
Clusters of miRNA expression and enriched pathways. (A) Heatmap of differentially expressed miRNAs of six clusters. Down, miRNAs with expression of log2(AD/NC) or log2(PD/NC) < -1; NA, miRNAs with expression of -1 < log2(AD/NC) or log2(PD/NC) < 1; Up, miRNAs with expression of log2(AD/NC) or log2(PD/NC) > 1. (B) KEGG pathway of miRNAs from four clusters. Target genes of miRNAs were predicted by miRanda, TargetScan, and RNAhybrid individually. Joint target genes were selected and KEGG pathway enrichment analysis was carried out. Top three pathways of each cluster were shown. The size of the dots represents the -log10(p-value) of each pathway.
