Fig. 2From: Identification of potential blood biomarkers for early diagnosis of Alzheimer’s disease through RNA sequencing analysisDistribution of differentially expressed genes (DEGs). a Each point represents a gene. Green and red dots represent downregulated and upregulated DEGs, respectively. b Hieratical clustering of DEGs and samples by using the trimmed mean of M-values normalization factors. The horizontal and vertical axes represent the samples (AD, black; CN, gray) and DEGs (red, upregulated; green, downregulated), respectivelyBack to article page
