Mechanisms of Growth Hormone (GH) Action

Abstract excerpt

Many of the actions of growth hormone (GH) on somatic growth and tissue maintenance are mediated by insulin-like growth factor-I (IGF-I), a secreted protein whose gene expression is rapidly and potently induced by GH by unknown mechanisms. Recent studies implicating Stat5a and Stat5b in the growth response to GH in mice and observations linking Stat5b to control of IGF-I gene transcription in rats have prompted...
