(E) Log2-Ratios of the number of miRNA-binding sites found in significantly up- vs. downregulated genes in the somata (red) or processes (blue). Elevated ratio in processes indicates that miRNA-binding sites are more frequent in transcripts downregulated by PTX in processes. Non-parametric Mann-Whitney U-test was used to test difference (mean somata: 0.37 vs mean processes: 0.783); ***p-value < 0.0001; n=80 miRNAs, represented as colored datapoints.
