Examples for NF-κB mRNA expression in the tumorous sections of CRC patients. (A) positive tissue section, >50% stained cells, and (B) tissue section, 5%-25% stained cells with stained stromal cells. Examples for IL-8 mRNA expression in CRC patients at (C) score 2, 11%-50% stained cells and at (D) score 1, 1%-10% stained cells. Cells stained positive are shown with dark color of NBT/BCIP in the nuclei of glandular cells (adenocarcinoma cells) (×400) and pointed by black bold arrow.
