Figure 3: Volcano plots of differentially expressed long noncoding RNAs (lncRNAs) in each group after ischemic stroke. (A) Distribution of lncRNA expression in the IR group compared with the sham group. (B) Distribution of lncRNA expression in the ISP group compared with the sham group. (C) Distribution of lncRNA expression in the RIP group compared with the sham group. (D) Distribution of lncRNA expression in the ISP group compared with the IR group. (E) Distribution of lncRNA expression in the RIP group compared with the IR group. (F) Distribution of lncRNA expression in the ISP group compared with the RIP group. The screening threshold was defined as P < 0.05 by default. IR: Ischemia/reperfusion; ISP: in situ ischemic postconditioning; RIP: remote ischemic postconditioning.
