N2 - Glucagon-like peptide-1 (GLP-1) is an incretin hormone used therapeutically in type 2 diabetes and obesity. The interplay between ambient free fatty acids (FFAs) and GLP-1 remains unclear. Acipimox suppresses adipose tissue lipolysis via activation of the PUMA-G (also known as HCA2 and GPR109a) receptor. Objective: To investigate whether lowering of serum FFA level with acipimox affects GLP-1 secretion. Design: Two randomized crossover studies were performed in human subjects. Rat intestine was perfused intra-arterially and intraluminally, and L-cells were incubated with acipimox. Participants: The participants were healthy overweight subjects and hypopituitary adult patients. Interventions: The overweight participants received acipimox 250 mg 60 minutes before an oral glucose test. The hypopituitary patients received acipimox 250 mg 12, 9, and 2 hours before and during the metabolic study day, when they were studied in the basal state and during a hyperinsulinemic euglycemic clamp.
