Background

COX2 (Cyclooxygenase 2) is an inducible enzyme. It is involved in the response of cells to growth factors, tumor promoters, and cytokines that induce its expression. Given its role in synthesizing prostaglandins, COX2 is therefore of interest in studying immune response regulation. COX2 is induced by a wide variety of stimuli and was initally identified as immediate early growth response gene. In addition, COX2 expression markedly increased in 85-90% of human colorectal adenocarcinoma whereas COX1 levels remain unchanged.

  Details:
  COX-2 antibody used for IHC-P on sections of colonic lesions from Rats subjected to acetic acid-induced experimental colitis followed by treatment or not with Spirulina platensis/SP, Dunaliella salina/DS extracts or Sulfasalazine/SSZ (standard drug used to treat bowel inflammation, diarrhea, rectal bleeding, and abdominal pain in patients with ulcerative colitis). The acetic acid-treated group depicted severe immunoreactiivity of COX2 in mucosa, submucosa and muscularis, while the control as well as the ones treated with SP or SSZ had no COX2 expression. Dunaliella-treated/DS group however had considerable levels of COX2 expression in mucosa and submucosa layers of the colon tissue (Figure 5). Spirulina platensis exerted superior beneficial effects in alleviating acetic acid-induced colitis via anti-inflammatory actions which were even better than SSZ.
