The results revealed expressed CYCS and NFKB1 in normal rectum tissues and their lower expression in CRC tissues (Figures 5(a) and 5(e)) and also revealed underexpressed IKBKB and TRADD in normal rectum tissues and their higher expression in CRC tissues (Figures 5(c) and 5(g)). Here, IKBKB is linked to colorectal carcinoma.
