Therefore, we studied the effect of GIP on glucagon secretion under normoglycaemic conditions.METHODS: Ten healthy subjects (9 men, 1 woman; age 33+/-11; BMI 26.8+/-2.2 kg/m(2)) received three different doses of intravenous GIP (7, 20, and 60 pmol/kg body weight) and placebo. Venous blood samples were drawn over 30 min for glucagon and GIP concentrations (specific radioimmunoassays). In addition, 31 healthy subjects (16 men, 15 women; 42+/-11 years; BMI 24.4+/-2.7 kg/m(2)) were studied with 20 pmol GIP/kg. Statistics were done with RM-ANOVA and Duncan's post hoc tests.RESULTS: Gastric inhibitory polypeptide dose-dependently stimulated glucagon secretion ( p=0.019) with a maximal increment after 10 min. Incremental glucagon concentrations (Delta(10-0 min)) were 0.1+/-0.7, 1.4+/-0.5, 2.4+/-0.5, and 3.4+/-0.8 pmol/l (for placebo and for 7, 20, and 60 pmol GIP/kg, respectively; p=0.017). After the injection of 20 pmol GIP/kg b.w. in 31 healthy subjects, glucagon concentrations increased over the baseline from 7.5+/-0.5 to 9.3+/-0.7 pmol/l ( p=0.0082).CONCLUSIONS/INTERPRETATION: Glucagon secretion is dose-dependently stimulated by GIP at basal glucose concentrations. The absence of a glucagonotropic GIP effect in previous studies could be due to the hyperglycaemic conditions used in these experiments.
