# Identification of marker genes for spinal cord injury

## TL;DR

This study identifies four genes linked to spinal cord injury, which could help develop new treatments for this disabling condition.

## Contribution

The study identifies and experimentally validates four novel marker genes (Icam1, Ch25h, Plaur, Tm4sf1) associated with spinal cord injury.

## Key findings

- Four genes (Icam1, Ch25h, Plaur, Tm4sf1) were identified as differentially expressed in spinal cord injury.
- The identified genes were validated using PCR and immunohistochemistry in SCI rat models.
- The study links SCI with immune cell involvement through gene expression analysis.

## Abstract

Spinal cord injury (SCI) is a profoundly disabling and devastating neurological condition, significantly impacting patients’ quality of life. It imposes unbearable psychological and economic pressure on both patients and their families, as well as placing a heavy burden on society.

In this study, we integrated datasets GSE5296 and GSE47681 as training groups, analyzed gene variances between sham group and SCI group mice, and conducted Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis based on the differentially expressed genes. Subsequently, we performed Weighted Gene Correlation Network Analysis (WGCNA) and Lasso regression analyses.

We identified four characteristic disease genes: Icam1, Ch25h, Plaur and Tm4sf1. We examined the relationship between SCI and immune cells, and validated the expression of the identified disease-related genes in SCI rats using PCR and immunohistochemistry experiments.

In conclusion, we have identified and verified four genes related to SCI: Icam1, Ch25h, Plaur and Tm4sf1, which could offer insights for SCI treatment.
