ABSTRACT

 

Asgari Safdar AH, Ghaem Maghami SPM., Expression of glucagon-like peptide-2 receptor in bovine rumen epithelial and gastrointestinal tissues, Onl J Vet Res., 18(8): 680-687,  2014. The presence of glucagon9like peptide92 receptor (GLP92R) in bovine rumen epithelium and gastrointestinal tract tissue from 4 steers is reported.  Results from quantitative RT9PCR indicated GLP92R mRNA in the rumen epithelium, omasum, abomasum, duodenum, jejunum, ileum, large intestine and pancreas.  Expression of mRNA for GLP92R in pre-gastric bovine tissues was numerically less than in lower gastrointestinal tract tissue.  The greatest expression of mRNA for GLP92R was in the small and large intestine.  The jejunum and ileum had numerically greater concentrations of GLP92R mRNA than the duodenum whereas rumen epithelium and abomasum had the lowest levels.  Western blot analysis revealed the greatest density of GLP92R protein in rumen epithelium obtained from the ventral sac.  Results of this investigation demonstrate the presence of the glucagon9like peptide92 receptor in bovine tissue responsible for mediating the actions of hormone GLP92.  Further investigations are warranted to determine the actions and potential implications of GLP92 in the bovine.

 

Key Words: Glucagon-like peptide-2, Bovine, Rumen epithelial, Expression.
