From this, we found a number of pathways of interest that were differentially expressed in colorectal cancer: the p53 signalling pathway (hsa41105, p = 2.24 × 10–53, FDRp = 1.06 × 10–51), NF-kappa-B signalling pathway (hsa040605, p = 1.75 × 10–47, FDRp = 4.95 × 10–46) and the “colorectal cancer” pathway (hsa03030, p = 2.06 × 10–41, FDRp = 5.41 × 10–41) were all over-expressed in this cohort of patients. This evidence concerns the gene TP53 and colorectal cancer.
