`
`The therapeutic potential of glucagon-like peptides (GLPs), particularly glucagon-like
`peptide-1 (GLP-1), is only now beginning to be realized at the start of the twenty-first
`century. It was, however, the discovery of secretin in 1902 by Bayliss and Starling [1]
`that initiated interest in the endocrine function of the gut and pancreas. These
`scientists speculated that signals arising from the gut could elicit an endocrine
`response affecting carbohydrate disposal. In 1929, Zunz and LaBarre described an
`intestinal extract that could produce hypoglycemia [2], and in a separate paper,
`LaBarre used the term "incretin" to describe activity in the gut that might stimulate
`pancreatic endocrine secretions [3]. Despite initial interest in "incretin," research
`virtually stopped in this area due to the outbreak of World War II and the publication
`of several negative papers by Ivy and colleagues [4-6). Twenty-five years later,
`McIntyre suggested that a humoral subs tance was released from the jejunum during
`glucose absorption, acting in concert with glucose to stimulate insulin release from
`pancreatic ~-cells [7]. In 1969, Unger and Eisentraut referred to the gut- pancreas
`association as the enteroinsular axis [8), and this axis was subsequently described as
`involving nutrient, neural, and hormonal signals from the gut lo the pancreatic islet
`cells. To be termed an "increlin," any substance acting on this patJ1way must be
`secreted in response to nutrient stimuli and must stimulate glucose-dependent
`insulin secretion [9).
`A second incretin hormone, following the discovery of glucose-dependent in(cid:173)
`sulinotropic polypeptide (GIP), was postulated lo exist as a consequence of the
`doningof cDNAs encoding the preproglucagon gene in anglerfish pancreas [10-12].
`Habener and colleagues conducted some of the very early work to characterize
`preproglucagon, but it was Bell who first identified GLP-1(1-37) [13]. In 1986/ 1987, it
`was discovered that the truncated forms, GLP-1(7-37) and (7-36)amide, were the
`active insulinotropic isoforms of G LP-1 [14, 15]. Lowering of blood glucose with G LP-
`1 was first shown in three studies by Nathan, Nauck, and Kreymann [16- 18], with the

`The binding affinity and biological activity are particularly affected by His on
`position 7, Glyon position 10, Phe on position 12, Thr on position 13, Asp on position
`15 (all directly involved in receptor interaction), Phe on position 28, and Ile on
`position 29 (21]. The conformation ofGLP-1 includes an N-terrninal random coil and
`two helical segments joined by a linker region; this closely resembles the structure of
`glucagon (22].
`The preproglucagon gene is expressed in several cell types in the body. The
`pancreas contains a - and ~-cells: a -
