Fig. 2From: Three nervous system-specific expressed genes are potential biomarkers for the diagnosis of sporadic amyotrophic lateral sclerosis through a bioinformatic analysisIdentification of DEGs. A Heatmap of DEGs between sALS samples and nonneurological control samples based on GSE833 and GSE26276. Red rectangles and blue rectangles represent high and low expression, respectively. B Volcano plot of DEGs between sALS samples and nonneurological control samples based on GSE833 and GSE26276. Red plot, green plot and gray plot represent upregulated genes, low upregulated genes and nonsignifcant genes, respectively. C Eight DEGs were found both in GSE833 and GSE26276Back to article page
