Abstract:
The growth hormone receptor has been an archetype for ligand-induced receptor dimerisation in cytokine receptor signalling. However, we now know that it exists as a constitutive dimer and is activated by a reorganisation of receptor subunits as a result of asymmetric placement of two receptor binding sites on the hormone monomer. This review highlights several topics including: current models of receptor activation; recent advances in the understanding of GH signalling demonstrating that ligand-induced signalling activates Src/ERK pathway in parallel to the classical JAK2-STAT5 signalling; and the nuclear localised growth hormone receptor correlates with high proliferation status and carcinogenesis.

Secondary Messengers in Hormone Action
Many hormones bind to transmembrane G protein-coupled receptors that connect to regulatory G proteins. These G proteins can then activate enzymes such as adenylyl cyclase or phospholipase C. Adenylyl cyclase converts ATP to cAMP, activating...

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
