Abstract

Ulcerative colitis (UC) is a relatively frequent, chronic disease that impacts significantly the patient’s quality of life. Although many therapeutic options are available, additional approaches are needed because many patients either do not respond to current therapies or show significant side effects. Cardiotrophin-1 (CT-1) is a cytokine with potent cytoprotective, anti-inflammatory, and antiapoptotic properties. The purpose of this study was to assess if the administration of CT-1 could reduce colon damage in mice with experimental UC. UC was induced with 5% dextran sulfate sodium (DSS) in the drinking water. Some mice received i.v. dose of CT-1 (200 µg/kg) 2 hours before and 2 and 4 days after DSS administration. Animals were followed during 7 days after DSS. The severity of UC was measured by standard scores. Colon damage was assessed by histology and immunohistochemistry. Inflammatory mediators were measured by Western blot and PCR. CT-1 administration to DSS-treated mice ameliorated both the clinical course (disease activity index), histological damage, inflammation (colon expression of TNF-α, IL-17, IL-10, INF-γ, and iNOS), and apoptosis. Our results suggest that CT-1 administration before UC induction improves the clinical course, tissue damage and inflammation degree in DSS-induced UC in mice.
