Anorexia nervosa (AN), a state of chronic nutritional deprivation, is characterized by GH resistance with elevated GH levels and decreased levels of IGF-I. Fibroblast growth factor (FGF)-21, a hormone produced in the liver and adipocytes, is induced in the liver by fasting and peroxisome proliferator-activated receptor-alpha agonists. In a transgenic mouse model, FGF-21 reduces IGF-I levels by inhibiting signal transducer and activator of transcription-5, a mediator of the intracellular effects of GH.
