In addition, the mRNA expression of NF-κB and IL-8 was tested in tumorous and non-tumorous tissue sections of CRC versus that of adenoma patients (Tables 3 and 4) and in CRC S. gallolyticus seropositives (CRC-Sg+ve) versus that of CRC S. gallolyticus seronegatives (CRC-Sg-ve) (Tables 3 and 4). This evidence concerns the gene CXCL8 and adenoma.
