Ghrelin:RegulationofFoodIntakeandEnergyHomeostasis
The somatotropic axis. The synthesis and release of growth hormone (GH) from the pituitary are controlled by the hypothalamic hormones GH-releasing hormone (GHRH) and somatostatin (SRIF), which in turn are regulated by feedback (dashed lines) from blood GH and insulin-like growth factor-I (IGF-I) concentrations. The recently discovered endogenous GH-releasing peptide, called ghrelin, also stimulates GH release. Circu......阅读全文
