BIRC5/Survivin gene, of the IAP gene family, was significantly up-regulated in the 100 CRC tissues examined (mean ± SEM: 0.631 ± 0.06 fold expression units) compared to normal counterparts (mean ± SEM: 0.436 ± 0.04 fold expression units) at the mRNA level (p = 0.0003), as calculated by the Wilcoxon Signed Ranks test (Tables 1 and 2). This evidence concerns the gene BIRC5 and colorectal carcinoma.
