Abstract

Urotensin II (U-II) is a vasoactive peptide that interacts with a specific receptor named UTR. Recently, our group has demonstrated increased UTR expression in both human colon adenocarcinoma cell lines and adenomatous polyps, as well as in colon carcinoma samples if compared to healthy colon samples of the same patients. We also showed that an UTR agonist induced an increase in colon adenocarcinoma cell growth in vitro, whereas the UTR block with a specific antagonist caused an inhibition of their growth and an inhibition of about 50% of both motility and cell invasion. Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) associated with an increased baseline risk for colon cancer compared with the general population, and this risk is mostly attributed to chronic inflammation and immune dysregulation. This risk increases along with the duration of the disease, as demonstrated by many studies. There are no UTR expression data related to UC, and we therefore evaluated UTR expression in ill colon biopsies and in healthy colon ones of patients with UC and colon biopsies of healthy patients.
