Fig. 2From: Meta-analysis of human gene expression in response to Mycobacterium tuberculosis infection reveals potential therapeutic targetsThe heatmap of the subset 407 DEGs identified in the meta-analysis. For each DEG, its normalized expression value in each sample of the nine datasets was indicated in the heatmap. Two hundred forty one genes were up-regulated and 166 genes were down-regulated. The genes were clustered using the Ward’s method [56]. The samples were grouped first by comparison group then by individual studiesBack to article page
