Abstract

After spinal cord injury, dysregulated miRNAs appear and can participate in inflammatory responses, as well as the inhibition of apoptosis and axon regeneration through multiple pathways. However, the functions of miRNAs in spinal cord ischemia-reperfusion injury progression remain unclear. miRCURY LNATM Arrays were used to analyze miRNA expression profiles of rats after 90 minutes of ischemia followed by reperfusion for 24 and 48 hours. Furthermore, subsequent construction of aberrantly expressed miRNA regulatory patterns involved cell survival, proliferation, and apoptosis. Remarkably, the mitogen-activated protein kinase (MAPK) signaling pathway was the most significantly enriched pathway among 24- and 48-hour groups. Bioinformatics analysis and quantitative reverse transcription polymerase chain reaction confirmed the persistent overexpression of miR-22-3p in both groups. These results suggest that the aberrant miRNA regulatory network is possibly regulated MAPK signaling and continuously affects the physiological and biochemical status of cells, thus participating in the regulation of spinal cord ischemia-reperfusion injury. As such, miR-22-3p may play sustained regulatory roles in spinal cord ischemia-reperfusion injury. All experimental procedures were approved by the Animal Ethics Committee of Jilin University, China [approval No. 2020 (Research) 01].

摘要

脊髓损伤后,失调的微小RNA(miRNA)出现,并可通过多种途径参与炎症反应,以及抑制细胞凋亡和轴突再生。然而,miRNA在脊髓缺血再灌注损伤进展中的作用仍不清楚。使用miRCURY LNA™ 芯片分析大鼠在缺血90分钟后再灌注24小时和48小时后的miRNA表达谱。此外,随后构建的异常表达miRNA调控模式涉及细胞存活、增殖和凋亡。值得注意的是,丝裂原活化蛋白激酶(MAPK)信号通路是24小时和48小时组中最显著富集的通路。生物信息学分析和定量逆转录聚合酶链反应证实两组中miR-22-3p均持续过度表达。这些结果表明,异常的miRNA调控网络可能调节MAPK信号通路,并持续影响细胞的生理和生化状态,从而参与脊髓缺血再灌注损伤的调节。因此,miR-22-3p可能在脊髓缺血再灌注损伤中发挥持续的调节作用。所有实验程序均经中国吉林大学动物伦理委员会批准[批准号:2020(研究)01]。
