Interaction network analyses of the PDHS-specific and PQDS-specific genes in leukocytes. a The network detailing the interactions of PDHS-specific genes. b The network generated to show interactions of PQDS-specific genes. The number marked in a node indicates the count of the PQDS-specific or PDHS-specific miRNAs which were validated targeting to the corresponding node gene. The node genes-enriched pathways were specially marked in the interaction networks.
