Growth Hormone Receptor Expression in the Rat Gastrointestinal Tract*
Endocrinology, 1990We have used immunohistochemistry to define the cellular distribution of GH receptors in the gastrointestinal tract (GIT) and its derivatives. Immunohistochemistry was performed in the adult rat GIT with a panel of characterized monoclonal antibodies to the GH receptor. The most intense and heterogeneous immunoreactivity was observed in epithelial cell

The mechanisms mediating the proliferative effects of gastrointestinal (GI) peptide hormones and their cognate G protein-coupled receptors are associated intimately with epidermal growth factor (EGF) receptor-regulated signaling pathways. Although transactivation of the EGF receptor is now recognized as a critical component in GI peptide hormone ...

Hormone-Producing Gastrointestinal Tumors Contain a High Density of Somatostatin Receptors
The Journal of Clinical Endocrinology & Metabolism, 1987Fourteen hormone-producing gastrointestinal tract tumors were tested for their content of somatostatin (SRIH) receptors, using receptor autoradiography and in vitro binding assay with tumor homogenates. All four gastrinomas tested had high levels of SRIH receptors, as did two of five insulinomas and four of five vasoactive intestinal peptide-producing ...

Agonists targeting the receptors of incretin hormones, glucagon-like peptide-1 and glucose-dependent insulinotropic peptide, have been well established for the treatment of type 2 diabetes mellitus. There is increasing awareness that gastroenterologists and hepatologists should be treating obesity when patients present to their clinics.

Hormones and Receptors in Gastrointestinal Malignancies
Digestion, 1990Receptors for several polypeptide hormones have been demonstrated in cells of the gastrointestinal tract and pancreas. Some of these polypeptides stimulate or inhibit cell division. Therefore, these receptors have been sought in carcinomas arising from these tissues, and several examples have been reported.

Surgery Today, 1998
To determine whether a correlation exists between hormone receptors and their proliferative activities, the levels of estrogen receptors (ER) and progesterone receptors (PgR) in surgical specimens from 23 patients with gastric cancer and from 32 patients with colorectal cancer were investigated using an enzyme immunoassay. These values were examined in

Gastrointestinal hormone receptors on isolated smooth muscle cells from gastric antrum of the rabbit
Biochemical Pharmacology, 1989The regulation by gastrointestinal polypeptide hormones of contraction and relaxation of functionally isolated smooth muscle cells from gastric antrum of the rabbit has been investigated. Gastrin, cholecystokinin (CCK-8) and motilin induced a rapid contraction of isolated cells: significant response occurred within a 5-sec incubation with these ...

We characterized the effect of the specific cholecystokinin (CCK) receptor antagonist loxiglumide (CR 1505) on gallbladder contraction, pancreatic enzyme output and plasma CCK concentrations determined by radioimmunoassay and bioassay. Gallbladder emptying and bilirubin output in response to the intraduodenal administration of a mixed liquid meal were ...

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1995
Distribution of transcripts for prolactin and growth hormone receptors (PRLR and GHR) and their isoforms was characterized in the gastrointestinal (GI) tract from several species by reverse transcription-polymerase chain reaction combined with Southern analysis.

Neuroscience, 2003
The peptide hormone ghrelin is known to be present within stomach and, to a lesser extent, elsewhere in gut. Although reports suggest that gastric function may be modulated by ghrelin acting via the vagus nerve, the gastrointestinal distribution and functions of its receptor, the growth hormone secretagogue receptor (GHS-R), are not clear and may show ...
