Porcine pancreatic phospholipase A2 stimulates secretin release from secretin-producing cells. (1/608)

We have isolated, from canine pancreatic juice, two 14-kDa proteins with secretin-releasing activity that had N-terminal sequence homology with canine pancreatic phospholipase A2 (PLA2). In this study we have obtained evidence that secretin-releasing activity is an intrinsic property of pancreatic PLA2. Porcine pancreatic PLA2 from Sigma or Boehringer Mannheim was fractionated into several peaks by reverse phase high performance liquid chromatography. They were tested for stimulation of secretin release from murine neuroendocrine intestinal tumor cell line STC-1 and secretin cells enriched mucosal cell preparations isolated from rat upper small intestine. Each enzyme preparation was found to contain several components of secretin-releasing activity. Each bioactive fraction was purified to homogeneity by rechromatography and then subjected to mass spectral analysis and assays of PLA2 and secretin-releasing activities. It was found that the fraction with highest enzymatic activity also had the highest secretin-releasing activity and the same Mr as porcine pancreatic PLA2. Moreover, it also had the same N-terminal amino acid sequence (up to 30 residues determined) as that of porcine pancreatic PLA2, suggesting that it was identical to the enzyme. Purified porcine pancreatic PLA2 also stimulated secretin release concentration-dependently from both STC-1 cells and a mucosal cell preparation enriched in secretin-containing endocrine cells isolated from rat duodenum. Abolishment of the enzymatic activity by pretreatment with bromophenacyl bromide did not affect its secretin-releasing activity. The stimulatory effect of purified pancreatic PLA2 on secretin secretion from STC-1 cells was inhibited by an L-type Ca2+ channel blocker, by down-regulation of protein kinase C or by pretreatment of the cell with pertussis toxin. It is concluded that porcine pancreatic PLA2 possesses an intrinsic secretin-releasing activity that was independent of its enzymatic activity. This action is pertussis toxin-sensitive and is in part dependent on Ca2+ influx through the L-type channel and activation of protein kinase C.  (+info)

COOH-terminally extended secretins are potent stimulants of pancreatic secretion. (2/608)

Posttranslational processing of preprosecretin generates several COOH-terminally extended forms of secretin and alpha-carboxyl amidated secretin. We used synthetic canine secretin analogs with COOH-terminal -amide, -Gly, or -Gly-Lys-Arg to examine the effects of COOH-terminal extensions of secretin on bioactivity and detection in RIA. Synthetic products were purified by reverse-phase and ion-exchange HPLC and characterized by reverse-phase isocratic HPLC and amino acid, sequence, and mass spectral analyses. Secretin and secretin-Gly were noted to coelute during reverse-phase HPLC. In RIA using eight different antisera raised against amidated secretin, COOH-terminally extended secretins had little or no cross-reactivity. Bioactivity was assessed by measuring pancreatic responses in anesthetized rats. Amidated canine and porcine secretins were equipotent. Secretin-Gly and secretin-Gly-Lys-Arg had potencies of 81 +/- 9% (P > 0.05) and 176 +/- 13% (P < 0.01), respectively, compared with amidated secretin, and the response to secretin-Gly-Lys-Arg lasted significantly longer. These data demonstrate that 1) amidated secretin and secretin-Gly are not separable under some chromatographic conditions, 2) current RIA may not detect bioactive COOH-terminally extended forms of secretin in tissue extracts or blood, and 3) the secretin receptor mediating stimulation of pancreatic secretion recognizes both amidated and COOH-terminally extended secretins.  (+info)

Secretagogue-induced digestive enzyme activation and cell injury in rat pancreatic acini. (3/608)

The mechanisms responsible for intrapancreatic digestive enzyme activation as well as the relationship between that activation and cell injury during pancreatitis are not understood. We have employed an in vitro system in which freshly prepared pancreatic acini are exposed to a supramaximally stimulating concentration of the CCK analog caerulein to explore these issues. We find that in vitro trypsinogen activation depends on the continued presence of Ca2+ in the suspending medium and that it is half-maximal in the presence of 0.3 mM Ca2+. Caerulein-induced trypsinogen activation can be halted by removal of Ca2+ from the suspending medium or by chelation of intracellular Ca2+. Increasing intracellular Ca2+ with either ionomycin or thapsigargin does not induce trypsinogen activation. We have monitored cell injury by measuring the leakage of lactate dehydrogenase (LDH) from acini and by quantitating intercalation of propidium iodide (PI) into DNA. Leakage of LDH and intercalation of PI in response to supramaximal stimulation with caerulein can be detected only after caerulein-induced trypsinogen activation has already occurred, and these indications of cell injury can be prevented by addition of a cell-permeant protease inhibitor. Our findings indicate that caerulein-induced intra-acinar cell activation of trypsinogen depends on a rise in intracellular Ca2+, which reflects entry of Ca2+ from the suspending medium. Intra-acinar cell activation of trypsinogen is an early as well as a critical event in pancreatitis. The subsequent cell injury in this model is mediated by activated proteases.  (+info)

Vagus nerve modulates secretin binding sites in the rat forestomach. (4/608)

Secretin is well known for its inhibitory action on gastric motility. It has been reported that secretin in a physiological dose inhibits gastric motility through mediation by the vagal afferent pathway. Secretin also elicited relaxation of carbachol-stimulated rat forestomach muscle strips by binding to its receptors, suggesting a direct action on this peripheral tissue. We hypothesized that vagal input may affect the action of secretin by modulating the level of secretin receptor in the forestomach. Several treatments, including vagal ligation, vagotomy, perivagal application of capsaicin or colchicine, intravenous infusion of tetrodotoxin, and intraperitoneal injection of atropine, were performed to investigate their effects on secretin receptor binding to forestomach membranes. Specific binding of 125I-labeled secretin to forestomach membranes was significantly decreased (45%) by vagal ligation, vagotomy (50%), or perivagal colchicine treatment (40%). On the contrary, specific binding of 125I-secretin was not affected by perivagal capsaicin treatment, intravenous infusion of tetrodotoxin, or intraperitoneal injection of atropine. By Scatchard analysis of the binding data, the capacity of the high-affinity binding sites in forestomach membranes was found to decrease significantly after vagal ligation compared with membranes from the sham-operated group. However, the affinity at the high-affinity binding sites, the binding parameters of the low-affinity binding sites, and binding specificity were not changed. Vagal ligation but not perivagal capsaicin treatment reduced the inhibitory effect of secretin on bethanechol-stimulated contraction of isolated forestomach muscle strips, causing a right shift in the dose-response curve. These results suggest that vagal input through axonal transport plays a significant role on secretin action by modulating the capacity of secretin binding sites (but not affinity or specificity), at least in rat forestomach.  (+info)

Acute carbon tetrachloride feeding induces damage of large but not small cholangiocytes from BDL rat liver. (5/608)

Bile duct damage and/or loss is limited to a range of duct sizes in cholangiopathies. We tested the hypothesis that CCl4 damages only large ducts. CCl4 or mineral oil was given to bile duct-ligated (BDL) rats, and 1, 2, and 7 days later small and large cholangiocytes were purified and evaluated for apoptosis, proliferation, and secretion. In situ, we measured apoptosis by morphometric and TUNEL analysis and the number of small and large ducts by morphometry. Two days after CCl4 administration, we found an increased number of small ducts and reduced number of large ducts. In vitro apoptosis was observed only in large cholangiocytes, and this was accompanied by loss of proliferation and secretion in large cholangiocytes and loss of choleretic effect of secretin. Small cholangiocytes de novo express the secretin receptor gene and secretin-induced cAMP response. Consistent with damage of large ducts, we detected cytochrome P-4502E1 (which CCl4 converts to its radicals) only in large cholangiocytes. CCl4 induces selective apoptosis of large ducts associated with loss of large cholangiocyte proliferation and secretion.  (+info)

Similar structures and shared switch mechanisms of the beta2-adrenoceptor and the parathyroid hormone receptor. Zn(II) bridges between helices III and VI block activation. (6/608)

The seven transmembrane helices of serpentine receptors comprise a conserved switch that relays signals from extracellular stimuli to heterotrimeric G proteins on the cytoplasmic face of the membrane. By substituting histidines for residues at the cytoplasmic ends of helices III and VI in retinal rhodopsin, we engineered a metal-binding site whose occupancy by Zn(II) prevented the receptor from activating a retinal G protein, Gt (Sheikh, S. P., Zvyaga, T. A. , Lichtarge, O., Sakmar, T. P., and Bourne, H. R. (1996) Nature 383, 347-350). Now we report engineering of metal-binding sites bridging the cytoplasmic ends of these two helices in two other serpentine receptors, the beta2-adrenoreceptor and the parathyroid hormone receptor; occupancy of the metal-binding site by Zn(II) markedly impairs the ability of each receptor to mediate ligand-dependent activation of Gs, the stimulatory regulator of adenylyl cyclase. We infer that these two receptors share with rhodopsin a common three-dimensional architecture and an activation switch that requires movement, relative to one another, of helices III and VI; these inferences are surprising in the case of the parathyroid hormone receptor, a receptor that contains seven stretches of hydrophobic sequence but whose amino acid sequence otherwise shows no apparent similarity to those of receptors in the rhodopsin family. These findings highlight the evolutionary conservation of the switch mechanism of serpentine receptors and help to constrain models of how the switch works.  (+info)

Duodenal acid-induced gastric relaxation is mediated by multiple pathways. (7/608)

In this study, we used an in vivo anesthetized rat model to investigate the mechanisms responsible for duodenal acid-induced inhibition of gastric motility. Intraduodenal infusion of HCl produced a rate-dependent decrease in intragastric pressure. Infusion of HCl at 2 ml/h produced a physiological plasma secretin level and elicited a decrease in intragastric pressure of 3.0 +/- 0. 2 cmH20. Infusion of rabbit secretin antiserum reduced the acid-induced inhibition of gastric motility by 85 +/- 5%, suggesting mediation mainly by endogenous secretin. Administration of the cholecystokinin (CCK)-A antagonist MK-329 caused only a modest 10 +/- 3% reduction in gastric relaxation, whereas the serotonin antagonist ICS-205930 had no effect. In contrast, immunoneutralization with the secretin antibody caused only a 15% reduction in the relaxation evoked by a higher rate of HCl infusion (3 ml/h), whereas MK-329 and ICS-205930 caused a 20 +/- 4% reduction and no reduction, respectively. Bilateral truncal vagotomy or perivagal application of capsaicin completely abolished gastric relaxation in response to low rates (1-2 ml/h) of 0.1 N HCl infusion but only partially affected gastric relaxation in response to a higher infusion rate (3 ml/h). These observations indicate that multiple pathways mediate the duodenal acid-induced inhibition of gastric motility. At low rates of HCl infusion, gastric relaxation is mediated primarily by endogenous secretin, which acts through vagal afferent pathways. At higher rates of HCl infusion, gastric relaxation is mediated by endogenous secretin, CCK, and possibly by the direct action of HCl on vagal afferent pathways or yet unidentified neuropathways.  (+info)

Identification of an interaction between residue 6 of the natural peptide ligand and a distinct residue within the amino-terminal tail of the secretin receptor. (8/608)

Photoaffinity labeling is a powerful tool for the characterization of the molecular basis of ligand binding. We recently used this technique to demonstrate the proximity between a residue within the carboxyl-terminal half of a secretin-like ligand and the amino-terminal domain of the secretin receptor (Dong, M., Wang, Y., Pinon, D. I., Hadac, E. M., and Miller, L. J. (1999) J. Biol. Chem. 274, 903-909). In this work, we have developed another novel radioiodinatable secretin analogue ([Bpa6,Tyr10]rat secretin-27) that incorporates a photolabile p-benzoyl-L-phenylalanine (Bpa) residue into position 6 of the amino-terminal half of the ligand and used this to identify a specific receptor residue proximate to it. This probe specifically bound to the secretin receptor with high affinity (IC50 = 13.2 +/- 2.5 nM) and was a potent stimulant of cAMP accumulation in secretin receptor-bearing Chinese hamster ovary-SecR cells (EC50 = 720 +/- 230 pM). It covalently labeled the secretin receptor in a saturable and specific manner. Cyanogen bromide cleavage of this molecule yielded a single labeled fragment that migrated on an SDS-polyacrylamide gel at Mr = 19,000 that shifted to 10 after deglycosylation, most consistent with either of two glycosylated fragments within the amino-terminal tail. By immunoprecipitation with antibody directed to epitope tags incorporated into each of the two candidate fragments, the most distal fragment at the amino terminus was identified as the domain of labeling. The labeled domain was further refined to the first 16 residues by endoproteinase Lys-C cleavage and by cyanogen bromide cleavage of another receptor construct in which Val16 was mutated to Met. Radiochemical sequencing of photoaffinity-labeled secretin receptor fragments established that Val4 was the specific site of covalent attachment. This provides the first residue-residue contact between a secretin ligand and its receptor and will contribute substantially to the molecular understanding of this interaction.  (+info)

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 ...

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.

Effect of exogenous cholecystokinin and secretin on pancreatic secretion of insulin and glucagon in rats. Academic Article 2001 ...
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 ...

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 ...

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a G protein-coupled receptor and belongs to the glucagon-VIP-secretin receptor family. It binds secretin which is the most potent regulator of pancreatic bicarbonate, electrolyte and volume secretion. Secretin and its receptor are suggested to be involved in pancreatic cancer and autism. [provided by RefSeq, Jul 2008 ...
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)]. GPCRs are major drug targets, and are consequently ...

Acts as a transcriptional activator: mediates transcriptional activation by binding to E box-containing promoter consensus core sequences 5-CANNTG-3. Associates with the p300/CBP transcription coactivator complex to stimulate transcription of the secretin gene as well as the gene encoding the cyclin-dependent kinase inhibitor CDKN1A. Contributes to the regulation of several cell differentiation pathways, like those that promote the formation of early retinal ganglion cells, inner ear sensory neurons, granule cells forming either the cerebellum or the dentate gyrus cell layer of the hippocampus, endocrine islet cells of the pancreas and enteroendocrine cells of the small intestine. Together with PAX6 or SIX3, is required for the regulation of amacrine cell fate specification. Also required for dendrite morphogenesis and maintenance in the cerebellar cortex. Associates with chromatin to enhancer regulatory elements in genes encoding key transcriptional regulators of neurogenesis.
