Fig. 4

PIA gives a graphical output to facilitate the understanding of the pathway relationship amongst genes. The intensity of the color of the red diamonds give an idea of the expression level of the pathway. Furthermore, fixing anagen as reference, the color intensity of the red balloon highlights the up-regulation in catagen. While the intensity of the green balloon gives information about the down-regulation in catagen.
