We also confirmed that the serum concentrations of IL-8 (Supplemental Fig.  1A), eotaxin-1 (Supplemental Fig.  1B), MIP-1a (Supplemental Fig.  1C), and MCP-1 (Supplemental Fig.  1D) were significantly increased in the sera of CRC patients compared to healthy controls. This evidence concerns the gene CCL11 and colorectal carcinoma.
