Heatmap and median profiles of clustered genes. Clustering results on the 650 differentially expressed genes : cluster \(\mathcal {D}_{+}\) (green), \(\mathcal {D}_{-}\) (dark green) for down-regulation, \(\mathcal {U}_{\simeq }\) (orange), \(\mathcal {U}_{+}\) (red) and \(\mathcal {U}_{-}\) (dark red) for up-regulation. We have highlighted the median profile of the corresponding cluster in black and left the median profiles of the other clusters in grey in the background to facilitate visual comparison
