Figure 1 depicts the immunohistochemical color development results: (a) illustrates the TNFAIP3 protein expression in adjacent tissues, and (b) illustrates the TNFAIP3 protein expression in cancerous tissues, (c) NFκB expression in adjacent tissues, and (d) NFκB expression in cancerous tissues; Table 1 summarizes the expression of TNFAIP3 and NFκB protein expressions in CRC (the positive expression was mainly in cytoplasm). Here, NFKB1 is linked to colorectal carcinoma.
