Figure Lengend Snippet: Circulating GDF15 levels increase in individuals with PBH after a mixed meal (A) Experimental design. Blood samples were collected from 15 individuals with PBH, 15 asymptomatic (Asx) individuals, and 10 overweight/obese (Ow/Ob) controls at 0, 30, and 120 min during a mixed-meal test. (B) Plasma glucose measured by yellow springs instruments (YSI). (C) Glucose nadir. (D–G) Plasma insulin, C-peptide, GLP-1, and GDF15 measured by ELISA. (H–P) Pearson correlation analyses between GDF15 and plama glucose (H–J), insulin (K–M), and GLP-1 (N–P) at fasting state, 30 min, and 120 min after meal digestion. Data are represented as mean ± SD. ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001, ∗∗∗ p < 0.0001.
Article Snippet: Plasma collected at baseline (fasting) and at 30 and 120 min following the mixed meal, or plasma collected at baseline (fasting) and at 40 and 100 min after initiation of the hyperinsulinemic hypoglycemic clamp was assayed by human GDF15 ELISA (R&D systems, Minneapolis, MN, USA, DGD150) following the manufacturer’s instructions.
