The Psp system is a widely conserved stress response triggered by events that can affect the integrity of the cytoplasmic membrane and perhaps cause aberrant transmembrane ion gradients (reviewed in reference 10). Many stimuli that induce psp gene expression, such as heat, ethanol, osmotic shock, or proton ionophores, also cause numerous other transcriptional responses. However, a notable exception is the mislocalization of a secretin, which induces only the psp genes (27, 50). Furthermore, in Y. enterocolitica it may be that only psp null mutations cause severe and specific sensitivity to secretins (50). We certainly do not contend that the only role of the Psp system is to deal with secretin-induced stress. Rather, it may have evolved as a more general response to stresses that can compromise cytoplasmic membrane integrity, with secretin mislocalization being just one example. Nevertheless, there is a highly specific and important relationship between the Psp system and secretin-induced ...
Previous studies have indicated that the G protein-coupled secretin receptor is present as a homo-dimer, organized through symmetrical contacts in transmembrane domain IV, and that receptor dimerization is critical for high potency signalling by secretin. However, whether all of the receptor exists in the dimeric form or if this is regulated, is unclear. We used measures of quantal brightness of the secretin receptor tagged with monomeric enhanced green fluorescent protein (mEGFP) and Spatial Intensity Distribution Analysis to assess this. Calibration using cells expressing plasma membrane-anchored forms of mEGFP initially allowed demonstration that the Epidermal Growth Factor receptor is predominantly monomeric in the absence of ligand and whilst wild type receptor was rapidly converted to a dimeric form by ligand, a mutated form of this receptor remained monomeric. Equivalent studies showed that at moderate expression levels the secretin receptor exists as a mixture of monomeric and dimeric ...
TY - JOUR. T1 - Secretin Provocation Test in the Diagnosis of Zollinger‐EIlison Syndrome. AU - Brady, Charles E.. PY - 1991/2. Y1 - 1991/2. N2 - The secretin stimulation test has become the preferred provocative test in suspected cases of Zollinger‐Ellison syndrome. A pure secretin preparation, a gastrin‐specific radioimmunoassay, and an appropriate sampling sequence are important for the proper interpretation of this test. Gastric acid analysis is necessary in the assessment of hypergastrinemia to confirm acid hypersecretion and exclude achlorhydria. When properly performed and interpreted, the secretin provocation test offers a safe, expeditious, and reliable means of evaluating patients with hypergastrinemia..

This study confirms the outcome of multiple other double blind, placebo controlled studies of the lack of efficacy of secretin in changing core symptoms of autism (table 1). Despite the extensive documentation of the lack of efficacy, reports on the Internet and demand for treatment with secretin still exist, including intravenous, transdermal,33 and sublingual administration.. In this study we attempted to address criticisms of previous studies using secretin as a potential treatment for children with autism. In some of the studies the diagnosis of autism or PDD was made by clinical impression or comparison with DSM-IV criteria or other checklist.14-17 We used the ADI-R to confirm the diagnosis in children previously diagnosed with autism or PDD. In their critique of the study of Sandler and colleagues,14 Horvath et al reported that younger, lower functioning, non-verbal patients with gastrointestinal symptoms were more likely to have a change in gastrointestinal symptoms following secretin ...

Secretin is a hormone that regulates water homeostasis throughout the body and influences the environment of the duodenum by regulating secretions in the stomach, pancreas, and liver. It is a peptide hormone produced in the S cells of the duodenum, which are located in the intestinal glands. In humans, the secretin peptide is encoded by the SCT gene. Secretin helps regulate the pH of the duodenum by (1) inhibiting the secretion of gastric acid from the parietal cells of the stomach and (2) stimulating the production of bicarbonate from the centroacinar cells and intercalated ducts of the pancreas. It also stimulates bile production by the liver; the bile emulsifies dietary fats in the duodenum so that pancreatic lipase can act upon them. Meanwhile, in concert with secretins actions, the other main hormone simultaneously issued by the duodenum, cholecystokinin, is stimulating the gallbladder to contract, delivering its stored bile for the same reason. Prosecretin is a precursor to secretin, ...

Aquaporin-1 (AQP1) water channels are present in the apical and basolateral plasma membrane domains of bile duct epithelial cells, or cholangiocytes, and mediate the transport of water in these cells. We previously reported that secretin, a hormone known to stimulate ductal bile secretion, increases cholangiocyte osmotic water permeability and stimulates the redistribution of AQP1 from an intracellular vesicular pool to the cholangiocyte plasma membrane. Nevertheless, the target plasma membrane domain (i.e., basolateral or apical) for secretin-regulated trafficking of AQP1 in cholangiocytes is unknown, as is the functional significance of this process for the secretion of ductal bile. In this study, we used primarily an in vivo model (i.e., rats with cholangiocyte hyperplasia induced by bile duct ligation) to address these issues. AQP1 was quantitated by immunoblotting in apical and basolateral plasma membranes prepared from cholangiocytes isolated from rats 20 min after intravenous infusion of secretin

The secretin receptor (SCTR) is a member of Class 2 subfamily B1 GPCRs and part of the PAC1/VPAC receptor subfamily. This receptor has long been known in mammals but has only recently been identified in other vertebrates including teleosts, from which it was previously considered to be absent. The ligand for SCTR in mammals is secretin (SCT), an important gastrointestinal peptide, which in teleosts has not yet been isolated, or the gene identified. This study revises the evolutionary model previously proposed for the secretin-GPCRs in metazoan by analysing in detail the fishes, the most successful of the extant vertebrates. All the Actinopterygii genomes analysed and the Chondrichthyes and Sarcopterygii fish possess a SCTR gene that shares conserved sequence, structure and synteny with the tetrapod homologue. Phylogenetic clustering and gene environment comparisons revealed that fish and tetrapod SCTR shared a common origin and diverged early from the PAC1/VPAC subfamily group. In teleosts SCTR ...
The liver produces bile which is stored in the gall bladder. It then flows down through the bile duct into the duodenum. It is a green liquid, a mixture of substances not all of which are involved in the digestion. The digestion components are inorganic components of sodium. These salts emulsify lipids by lowering their surface tension causing them to break up into numerous droplets there by increasing their surface area for enzyme action. The secretion of bile is controlled by a hormone CHOLECYSTOKININ, while its production in the liver is controlled by the hormone Secretin. Bile is also rich in sodium bicarbonate, which neutralizes the acid from the stomach. The PH of the small intestines is therefore alkaline, which favors the action of the various enzymes. The hormones secretin also stimulates the pancreas to release pancreatic juice into the duodenum via the pancreatic duct. Pancreatic juice contains three enzymes. ...
Patients with carboxyl-ester lipase-maturity-onset diabetes of the young (CEL-MODY) display distinct disease stages toward the development of monogenic diabetes and exocrine pancreatic disease. The finding of differentially increased proteins, some related to MAPK signaling, in a discovery proteomics study of secretin-stimulated duodenal juice in three CEL-MODY patients, prompted us to monitor their abundance in an extensive number of CEL-MODY subjects at different disease stages and controls using targeted proteomics. In the current study, we demonstrate the feasibility of selected reaction monitoring assays to quantify protein levels in secretin-stimulated duodenal juice. Furthermore, we define a set of five peptides for potential use as diagnostic tests in CEL-MODY patients. Finally, we propose a further set of seven proteins with a likely pathogenic role in CEL-MODY disease progression ...

Secretin stimulates the secretion of bicarbonate by the pancreas and inhibits the gastrin and acid production in the stomach. It also potentiates the release of digestive enzymes from the pancreas triggered by cholecystokinin.
Background Comparative approaches using protostome and deuterostome data have greatly contributed to understanding gene function and organismal complexity. The family 2 G-protein coupled receptors (GPCRs) are one of the largest and best studied hormone and neuropeptide receptor families. They are suggested to have arisen from a single ancestral gene via duplication events. Despite the recent identification of receptor members in protostome and early deuterostome genomes, relatively little is known about their function or origin during metazoan divergence. In this study a comprehensive description of family 2 GPCR evolution is given based on in silico and expression analyses of the invertebrate receptor genes. Results Family 2 GPCR members were identified in the invertebrate genomes of the nematodes C. elegans and C. briggsae, the arthropods D. melanogaster and A. gambiae (mosquito) and in the tunicate C. intestinalis. This suggests that they are of ancient origin and have evolved through ...

G protein-coupled receptors (GPCRs) constitute a vast protein family that encompasses a wide range of functions, including various autocrine, paracrine and endocrine processes. They show considerable diversity at the sequence level, on the basis of which they can be separated into distinct groups [(PUBMED:12679517)]. The term clan can be used to describe the GPCRs, as they embrace a group of families for which there are indications of evolutionary relationship, but between which there is no statistically significant similarity in sequence [(PUBMED:8170923)]. The currently known clan members include rhodopsin-like GPCRs (Class A, GPCRA), secretin-like GPCRs (Class B, GPCRB), metabotropic glutamate receptor family (Class C, GPCRC), fungal mating pheromone receptors (Class D, GPCRD), cAMP receptors (Class E, GPCRE) and frizzled/smoothened (Class F, GPCRF) [(PUBMED:8170923), (PUBMED:8081729), (PUBMED:15914470), (PUBMED:18948278), (PUBMED:16753280)].
