RNA sequencing screening of differentially expressed genes after spinal cord injury

Neural Regen Res, 2019 · DOI: 10.4103/1673-5374.255994 · Published: September 1, 2019

Simple Explanation

Spinal cord injury (SCI) can lead to lasting disabilities, and understanding the genes involved in the injury process is key to finding effective treatments. This study uses RNA sequencing technology to analyze changes in gene expression at different times after SCI in rats. The research identifies genes strongly linked to SCI, potentially providing new targets for treatment.

Study Duration

7 days

Participants

49 adult female Sprague-Dawley rats

Evidence Level

Not specified

Key Findings

1
RNA sequencing identified a significant number of differentially expressed genes at 1, 4, and 7 days after spinal cord injury in rats.
2
The genes C5ar1, Socs3, and CCL6 showed expression trends consistent with RNA sequencing results, suggesting their involvement in SCI.
3
C5ar1 protein expression was consistent with nucleic acid levels and mainly expressed in neurons and astrocytes after SCI.

Research Summary

This study used RNA-Seq technology to investigate the differences in transcriptome levels at different stages after SCI. The results of this study showed that compared with the sham group, the number of differentially expressed genes at 1, 4 and 7 days after SCI were 944, 1362 and 1421, respectively. C5ar1 and Itgb2, two prominent genes of particular interest, were selected from all the differential genes, and subjected to various experimental techniques to verify changes in their expression and analyze their functions.

Practical Implications

Targeted Therapies

Identified genes can serve as potential targets for developing therapies to treat spinal cord injury.

Understanding Mechanisms

The findings contribute to a deeper understanding of the molecular mechanisms underlying spinal cord injury.

Inflammation Reduction

Socs3 and CCL6 could be used as potential targets to reduce inflammatory responses as well as to improve the repair environment after SCI.
