PPI z-scores of regulatory motifs regulated by known and unknown interacting TF-TF/TF-miRNA pairs. The box-plots of PPI z-scores for regulatory motifs regulated by different combinations of regulators: (A) TF-TF and (B) TF-miRNA. The numbers next to the black lines in the box-plots represent the median of PPI z-scores.
