Figure 1 Venn diagram of common differentially expressed genes (DEGs). Intersections were analyzed among DEGs in GSE15041, GSE38038, GSE2884, and GSE24982 microarray datasets. The diagram was created by using a Venn diagram maker from the Van de Peer Lab. GSE15041 and GSE38038 were based on dorsal root ganglia collected on day 7 after spinal nerve ligation, while GSE2884 and GSE24982 were based on dorsal root ganglia collected on day 28.
