Figure 6. DElncRNA-selected neighboring genes regulatory network involved in immune processes. (a) Network of DElncRNAs (upregulated and downregulated) and the genes they regulate in the lung tissue. (b) Network of DElncRNAs (upregulated and downregulated) and the genes they regulate in the spleen tissue. DElncRNAs are represented by diamonds, with upregulated lncRNAs shown in red and downregulated lncRNAs in cyan. The neighboring genes are shown as ellipses, whose size is a function of their connectivity in protein-protein interactions (as shown in supplementary figure 2).
