Figure 7. The DEmiRNA-DEG regulatory network in MDD has been identified. Red represents up-regulation, green represents down-regulation, a triangle represents miRNA, and a prototype represents mRNA. There were 23 nodes and 18 interactions in the DEmiR-downDEG regulatory network. There were 23 nodes, with 4 down-regulated DEGs and 3 DEmiRNAs, 13 upregulated DEGs and 3 DEmiRNAs.
