Fig. 2From: Digital gene expression profiling analysis and its application in the identification of genes associated with improved response to neoadjuvant chemotherapy in breast cancerCluster analysis of gene expression based on digital gene expression sequencing (DGE-seq) data. The heat map reveals the results from the cluster analysis of the DGE-seq data. Each column represents one of the 715 differentially expressed genes identified in our study. Each row represents a sample. For each gene, red indicates a high level of expression relative to the mean, whereas green indicates a low level. The scale bar below indicates the number of standard deviations from the meanBack to article page
