OBJECTIVE This study aims to investigate gene expression changes in rat dorsal horns after sciatic nerve injury (SNI). METHODS The GSE18803 microarray data collected from young and adult rats were downloaded from GEO. After preprocessing, differentially expressed genes (DEGs) between SNI and sham-operated groups were selected using Limma package, in young and adult group, respectively, followed by Venn analysis. Then, enrichment analyses were performed for these DEGs using DAVID. The STRING database was used to identify protein-protein interactions (PPIs) among these DEGs, and the module network was further extracted using plugin ClusterONE. Finally, protein domain enrichment analysis of DEGs in each module was performed using InterPro database. RESULTS Totally, 210 and 50 DEGs were identified in adult and young group, respectively. Among them, 160 were specific in adult group (e.g. CCL2, NF-κB1 and RAC2); 9 were specific in young group (e.g. ILF3 and LYVE1); and 41 were common in both two groups (e.g. FCER1G, C1QA, C1QB and C1QC). The up-regulated DEGs were mostly enriched in immune response-related biological processes, as well as 15 immune- and inflammation-related pathways. Then, two modules were identified in PPI network. CCL2 and NF-κB1 had high connectivity degrees in module 1, and RAC2, FCER1G and CD68 in module 2. CONCLUSIONS CCL2, NF-κB1, RAC2, FCER1G and C1Q may contribute to the generation of neuropathic pain after SNI via immune and defense pathways. Among the five genes, the first three are specific in adult population, while the latter two are age-independent. They all might function through involvement of these immune or inflammatory pathways.

D020426 Sciatic Neuropathy Disease or damage involving the SCIATIC NERVE, which divides into the PERONEAL NERVE and TIBIAL NERVE (see also PERONEAL NEUROPATHIES and TIBIAL NEUROPATHY). Clinical manifestations may include SCIATICA or pain localized to the hip, PARESIS or PARALYSIS of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. The sciatic nerve may be affected by trauma; ISCHEMIA; COLLAGEN DISEASES; and other conditions.
