109-OR: GIP Acutely Blunts Insulin- and GLP-1–Induced Muscle Microvascular Perfusion
Cross-Sectional Study
Animal
The study tested exactly what the claim says: treating rat muscle blood vessel cells with GIP for 24 hours increased a substance that tightens blood vessels and blocked a substance that loosens them, which matches the claim perfectly.
