CircRNA, lncRNA and mRNA expression profiles after spinal cord injury in mouse model

To further explore the expression of circRNA, lncRNA and mRNA in mice with spinal cord contusion injury, we have employed microarray analysis as a discovery platform to identify circRNAs and lncRNAs with the potential to play role in the pathophysiology process of secondary injuryd after spinal cord injury. Three days after spinal cord injuryI, eight mice (SCI group, n=4; sham group, n=4) were anesthetized and the T9-T10 spinal cord segments centered on and enclosing the injured site were collected. And then total RNA was extracted and used for microarray detection. Four circRNAs from the top 30 differently expressed circRNAs were selected for real-time PCR. The expression patterns of these circRNAs were consistent with the microarray data validating the expression pattern observed by microarray analysis.
