Mechanisms of action of GH.

The process of growth, which is common to all multicellular organisms, is complex and involves the interaction of a multiplicity of factors; despite this, the GH/IGF function still maintains its preminence, and, in turn, the same is true for all approaches aimed at reducing the consequences of GH/IGF excess. In this review paper, we will deal briefly with some aspects of GH/IGF mechanism of action which are instrumental to the appreciation of a novel class of a "designer" GH antagonist, for use in conditions characterized by excess GH action and elevated serum IGF-I.
