Abstract
- Recent studies have shown that circular RNAs (circRNAs) are involved in many human diseases, but their roles in secondary damage after spinal cord injury (SCI) remain unclear. In the current study circRNA sequencing was performed in the damaged tissues of SCI rats on the seventh day after injury, and related molecular mechanisms were investigated. Quantitative PCR validations of molecules that exhibited significantly altered expression in SCI mice were performed. Gene ontology and Kyoto Encyclopedia of Genes and Genomes analyses were conducted to assess differentially expressed circRNAs. A novel circRNA‐2960 was the most significantly upregulated in the SCI group. It could downregulate its target molecule miRNA‐124, then exacerbate the inflammatory response and induce apoptosis at the lesion site. Disrupting circRNA‐2960 expression promoted recovery of tissues affected by secondary SCI damage. The results of the present study may provide new insight into the mechanisms of secondary injury in SCI, and a new molecular marker for the diagnosis and treatment of SCI. [ABSTRACT FROM AUTHOR]
