Figure 8  Identified master regulator PTK6 is shown at the top-most position of the schematic overview (pink rectangle), connecting molecules up to 10 steps upstream (green rectangles) starting from the identified transcription factors (blue rectangles). Strong red border lines indicate up-regulated genes and blue border lines down-regulated genes. The diagram is a result of the workflow shown in Figure 5, mapped with expression values. See Supplementary Figure SF4 for high-resolution version.
