Abstract

Intracerebroventricular (icv) injection of fibroblast growth factor 1 (FGF1) elicits remission of diabetic hyperglycemia in rodent models of type 2 diabetes. Here, we present an optimized protocol to study the intracellular signaling pathways underlying the FGF1-induced sustained glucose lowering in the mouse brain. This protocol combines icv injection of FGF1 and osmotic mini-pump infusion of U0126, an inhibitor of MAPK/ERK signaling. We describe the surgical procedure and verification of U0126 inhibition of FGF1-stimulated hypothalamic MAPK/ERK signaling via western blot. For complete details on the use and execution of this protocol, please refer to Brown et al.
