Abstract:

 As an intestinal-specific trophic factor,porcine glucagon-like peptide-2 (pGLP-2) could stimulate intestinal mucosal growth and reduce the severity of injury specificity.In order to provide a potential therapeutic agent for intestinal dysfunction and damage,the protective effects of pGLP-2 for colonic injury were measured in dextran sulfate sodium (DSS)-induced colitis in mice.Eighteen BALB/c mice were randomly assigned to three treatments for 10 days,mice of DSS group were fed 3% (w/v) DSS through their drinking water for 10 days from first day of experiment,mice of DSS+pGLP-2 group were extraperitoneally injected with pGLP-2 daily from day 3 to day 9 and drink 3% DSS.The water group received water normally.Results were as follows:DSS-induced colitis clearly decreased body weight and relative expression of zonula occludens-1 in the colon,which was significantly reduced by treatments with 3% DSS-pGLP-2.Administration of pGLP-2 to DSS-mice preserved normal colonic mucosal architecture and significantly decreased myeloperoxidase activity,the relative expression of interleukin-6,interleukin-10 and interferon-γ which induced by DSS.These results showed that pGLP-2 could reduce the severity of colonic injury in murine colitis.The potencies of this product highlight its potential as therapeutic agent for intestinal diseases in piglet.
