For example, the expression of CCL4, CCL5, CXCL9, HLAA, HLAB, HLAC, TAP1, and TAP2 was increased after FABP6 was suppressed in the CRC lines HCT116 and SW1116, indicating that the chemotaxis of various immune cells and antigen presentation of tumor cells were strongly enhanced. This evidence concerns the gene TAP2 and colorectal carcinoma.
