Identification of key genes and pathways associated with spinal cord injury.

ABSTRACT: The present study was designed to identify key genes or significant signaling pathways associated with spinal cord injury (SCI), and to clarify the underlying molecular mechanisms of SCI. Data from the GSE45550 array were downloaded from the Gene Expression Omnibus database. A total of 6 control samples, 6 samples at 3 days post‑SCI (SCI3d), 6 samples at 8 days post‑SCI (SCI8d) and 6 samples at 14 days post‑SCI (SCI14d) were included. The microarray data was preprocessed by the robust multi‑array average algorithm. The differentially expressed genes (DEGs) were identified using the limma package. The overlapping DEGs among groups were analyzed using the Venny 2.0 online tool. Modules enriched by DEGs were selected by weighted gene co‑expression network analysis. Gene Ontology annotation an
