From: Evidence for post-transcriptional regulation of clustered microRNAs in Drosophila
miRNAs with similar expression profiles mainly belong to the same clusters. (a) Pearson correlation coefficients r of expression profiles for miRNA pairs from the same cluster (cl.vs.cl.same), different clusters (cl.vs.cl.diff), clustered and non-clustered miRs (cl.vs.n-cl), and non-clustered miRNAs (n-cl.vs.n-cl.). (b) Frequency distributions of r in the same groups of miRNA pairs. Red and green arrows indicate highly and low correlated fractions of the clustered miRNAs in cl.vs.cl.same group, respectively. Distributions were normalized to the maximum value of frequency in each group.
