Food intake in lean and obese mice after peripheral administration of glucagon-like peptide 2
2012
We investigated the potential anorectic action of peripherally administered glucagon-like peptide 2 (GLP2) in lean and diet-induced obese (DIO) mice. Mice, fasted for 16 h, were injected i.p. with native GLP2 or [Gly2]GLP2, stable analog of GLP2, before or after GLP2 (3–33), a GLP2 receptor (GLP2R) antagonist, or exendin (9–39), a GLP1R antagonist. Food intake was measured at intervals 1, 2, 4, 8, and 24 h postinjection. In addition, we tested in lean mice the influence of [Gly2]GLP2 on gastric emptying and the effects of GLP1 alone or in combination with [Gly2]GLP2 on food intake. [Gly2]GLP2 dose dependently and significantly inhibited food intake in lean and DIO mice. The reduction of foo…
Peripheral Glucagon-like peptide 2 administration inhibits food intake in mice: Analysis of the mechanism of action.
2012
OBJECTIVE: Previously we showed that, in mice, peripheral administration of glucagon-like peptide 2 (GLP-2) or [Gly2]GLP-2, the degradation-resistant analogue of GLP-2, reduces food intake in the short term. The purposes of the present study were to compare the influence of [Gly2]GLP-2 with the anorectic effect induced by glucagon-like peptide 1 (GLP-1) and to analyze the mechanism of action responsible for GLP-2-induced effects. METHODS: Food intake was measured in mice, fasted for 16-18 h, at the first hour following peptide or vehicle intraperitoneally (i.p.) administration. The effects of GLP-2 (3-33), GLP-2 receptor (GLP-2R) antagonist, and exendin (9-39), GLP-1R antagonist were also e…
