Figure 9: Co-expression networks of all differentially expressed long noncoding RNAs (lncRNAs) and mRNAs in the cerebral tissue of IR rats with ISP and RIP treatment. LncRNA-mRNA co-expression networks were constructed for the IR vs. sham, ISP vs. IR, RIP vs. IR, and RIP vs. ISP group-wise comparisons. Upregulated lncRNAs are shown in red, downregulated lncRNAs are shown in green, and mRNAs are shown in blue. The ellipses represent mRNA, and the hexagons and quadrilaterals represent upregulated and downregulated lncRNAs, respectively. IR: Ischemia/reperfusion; ISP: in situ ischemic postconditioning; RIP: remote ischemic postconditioning.
