The genes selected for this analysis were the top-10 best survival marker genes found up-regulated for poor prognosis (i.e. markers up-regulated when there is low CRC survival): DCBLD2, PTPN14, LAMP5, TM4SF1, NPR3, LEMD1, LCA5, CSGALNACT2, SLC2A3 and GADD45B. This evidence concerns the gene GADD45B and colorectal carcinoma.
