Confirmation of RNA sequencing results: Heatmap of quantitative real-time RT-PCR and RNA-seq data for ten selected genes. To illustrate correlation of RNA seq and qPCR data relative expression levels (mean-centered log2 expression values) are shown as a heatmap. Red color means higher and blue lower expression levels of the gene compared to the mean of all samples, respectively (from 2 over 0 to −2)
