CXCL8 and adenoma: This indicated that mRNA expression of IL-8 and NF-κB in stromal cells, like glandular cells, showed association with CRC tumorous cells in comparison with non-tumorous and normal cells, however, unlike glandular cells, it showed no association with adenoma, the transformation process from adenoma to CRC, and no association with the seropositivity of S. gallolyticus IgG antibodies.
