Subnetwork analysis. (A, B and C) Phenotype-associated (subnetwork-P1, -P2 and -P3) and drug-associated (subnetwork-D1, -D2 and -D3) lncRNA-mRNA subnetworks were compared and analyzed, respectively. Subnetworks were constructed using the CytoHubba plugin. Advanced ranking of hub genes is represented by redder color. (D) Potential network of drug-lncRNA-mRNA-phenotype. Thirty-six anti-depression/anxiety drugs potentially act on 16 target lncRNAs to affect expression of the correlated 20 mRNAs. These lncRNAs and mRNAs were differentially expressed in the depression-susceptible (Dep-Sus), anxiety-susceptible (Anx-Sus) and insusceptible (Insus) groups.
