for the TP53 signaling pathway. Predicted protein folding effects are proportional to color intensity. The results
suggest perturbation of the cell cycle arrest or apoptosis pathway (cell type dependent) regulated by tumor
protein p53. Key proteins in this pathway with large codon frequency changes include p53, MDM2, ATR, PIDD,
IGF-BP3, IGF, Cyclin B, and Cyclin D. Note: The original TP53 signaling pathway was obtained from the freely
available Kegg Pathway Database (http:/
