The diagram of the cancer network which has 32 nodes and 111 edges. Red arrows denote activation while blue end points represent repression. Green nodes represent apoptosis marker genes; magenta nodes represent cancer marker genes; and light blue represent nodes tumor repressor marker genes. The brown nodes represent other genes. The solid black lines denote the key links, while the octagon nodes denote key genes found by the method of global sensitivity analysis.[39]
