Abstract
A peptide inhibiting the release of growth hormone was originally detected accidentally during studies of the distribution of growth hormone–releasing factor in the hypothalamus of rats.1 This peptide, called somatostatin, proved to be a cyclic peptide consisting of 14 amino acids.2 Subsequent work has considerably expanded this initially simple concept of somatostatin as a peptide whose main function is the regulation of growth hormone secretion.3 Today, somatostatin is best regarded as a phylogenetically ancient, multigene family of peptides with two important bioactive products: somatostatin-14 and somatostatin-28, the latter a congener of somatostatin-14 extended at the N-terminal.3,4 Like other peptide . . .
