Elevated M-acylCs impair first- and second-phase insulin release in isolated islets. M-acylC effect on GSIS was assessed in vitro by determining its dose-dependent effect on murine islets and is shown by insulin level (A) and fold response (B) to HG (n = 5/group). Insulin secretion in murine islets (n = 6/group) (C) and normal human islets (n = 4/group) (D) after a 28-h treatment with vehicle control or M-acylCs Physio and M-acylC Patho concentrations in vitro was assessed. The fold response to HG is shown as an inset. E: Insulin secretion in normal and T2D human islets (n = 5/group) was measured. Subsequently, T2D human islets were treated with M-acylCs Physio and M-acylCs Patho concentrations and insulin secretion assay was performed (n = 3/group). Fold response is shown as an inset. F: Dynamic insulin secretion was assessed in murine islets treated with M-acylCs Physio and M-acylCs Patho concentrations in vitro (n = 3/group). Area under the curve (AUC) is shown as an inset. Data are presented as mean ± SEM. *P < 0.05, **P < 0.01; n.s, not significant.
