Supplementary Figure 2: miRNA–mRNA node degree distribution.
From: Regulation of cell-type-specific transcriptomes by microRNA networks during human brain development
(a-b) each node in mode I (target genes, a) has significantly less connections with the opposite mode than mode II (targeting miRNA, b). (c) miRNA abundance shows a long-tailed distribution. (d) Abundance of miRNA members of each module is illustrated. Modules tend to either recruit several low-abundant miRNAs or few high-abundant miRNAs.
