Abstract

Spinal cord injury (SCI) is a cause of disability. The present study aimed to investigate the molecular mechanisms involved in traumatic SCI. Transcriptome data under accession no. GSE5296, including 96 chips, were downloaded from the Gene Expression Omnibus database. The raw data were normalized and differentially expressed genes (DEGs) were identified. Furthermore, Kyoto Encyclopedia of Genes and Genomes pathway and Gene Ontology enrichment analysis of up‑ and downregulated DEGs was performed. Additionally, a protein‑protein interaction network was constructed and the expression patterns of different genes were determined. Compared with sham samples, there were 374, 707, 1,322, 1,475, 1,724 and 1,342 DEGs identified at 0.5, 4, 24 and 72 h, and 7 and 28 days post‑injury, respectively. At 24 and 72 h, and 7 days following injury, the upregulated DEGs were markedly enriched in ‘inflammatory response’ and ‘immune process’. Downregulated DEGs were predominantly enriched in neuronal function‑associated pathways and ‘steroid biosynthesis’ process. Protein‑protein interaction network analysis demonstrated similar results. Trend charts further demonstrated that the inflammatory and neuronal functions were altered in a temporal and site‑specific manner. The present study provided an insight into the molecular mechanisms underlying traumatic SCI, which may benefit future SCI research and aid in therapy development.
