Twelve DEGs were identified by integrated analysis of AD gene expression datasets. a–c Clustering of the 12 DEGs in AD versus control across each independent dataset. Each column represents a sample and each row represents the expression level of a given gene. The color scale represents the raw Z score ranging from blue (low expression) to red (high expression). Dendrograms by each heatmap correspond to the hierarchical clustering by expression of the 12 genes. d Venn diagram of DEGs from three microarray datasets and genes list from text mining
