    ABSTRACT: We investigated, for the first time, the expression of I- and L-FABP in two very rare hereditary lipid malabsorption syndromes as compared with normal subjects. Abetalipoproteinemia (ABL) and Anderson's disease (AD) are characterized by an inability to export alimentary lipids as chylomicrons that result in fat loading of enterocytes. Duodeno-jejunal biopsies were obtained from 14 fasted normal subjects, and from four patients with ABL and from six with AD. Intestinal FABP expression was investigated by immuno-histochemistry, western blot, ELISA and Northern blot analysis. In contrast to normal subjects, the cellular immunostaining for both FABPs was clearly decreased in patients, as the enterocytes became fat-laden. In patients with ABL, the intestinal contents of I- (60.7 +/- 13.38 ng/mg protein) and L-FABP (750.3 +/- 121.3 ng/mg protein) are significantly reduced (50 and 35%, P < 0.05, respectively) as compared to normal subjects (I-135.3 +/- 11.1 ng, L-1211 +/- 110 ng/mg protein). In AD, the patients also exhibited decreased expression (50%, P < 0.05; I-59 +/- 11.88 ng, L-618.2 +/- 104.6 ng/mg protein). Decreased FABP expression was not associated with decreased mRNA levels. The results suggest that enterocytes might regulate intracellular FABP content in response to intracellular fatty acids, which we speculate may act as lipid sensors to prevent their intracellular transport.

    ABSTRACT: Some of the actions of leptin depend on cholecystokinin (CCK). However, it is unknown whether leptin modulates the release of CCK. Here, we demonstrate in vitro that leptin induces the phosphorylation of extracellular signal-related kinase (ERK)-1/2 proteins and increases CCK release (EC(50) = 0.23 nmol/l) in CCK-secreting STC-1 cells. We showed that rat duodenal juice contains leptin that circulates free and bound to macromolecules, suggesting that leptin has a lumenal action on the intestine. In vivo in the rat, duodenal infusion of leptin increased plasma CCK at levels comparable to those induced by feeding. Moreover, meal-induced increases in plasma CCK were markedly reduced in obese fa/fa rats, whereas the mobilization of the gastric leptin pool was similar in lean and obese Zucker rats. The release of CCK by leptin presumably generates a positive feedback loop. Indeed, the blockade of CCK receptors reversed the meal reduction of the stomach leptin pool and the meal-increased plasma insulin, consistent with the previous concept of an entero-insular axis. Collectively, these data support a novel mode of action of leptin where leptin and CCK may potentiate their own effects by cross-stimulating their secretion. The impairment of this leptin-CCK loop may have pathological implications related to obesity and diabetes.

    ABSTRACT: Helicobacter pylori may increase or inhibit gastric acid. We studied acid variations and plasma gastrin in cats harboring Helicobacter felis, harboring H. pylori, or free of gastric pathogens with reference to thioperamide (H(3) receptor antagonist) and SR-27417A (PAF receptor antagonist). In cats harboring H. felis, gastric mucosa were histologically normal. After H. felis eradication, pentagastrin-stimulated acid secretion was increased (40%) compared with the situation before eradication. Thioperamide abolished this inhibitory effect of H. felis, whereas SR-27417A did not. Basal and meal-stimulated plasma gastrin levels were not affected by eradication therapy. Acid secretion was inhibited (-80%) in week 3, increased from weeks 5 to 9, and remained constant for up to 42 weeks after H. pylori infection. SR-27417A had no effect on acid secretion before week 8 but inhibited it thereafter, and thioperamide increased it (20%) only before week 7 in those cats. Helicobacter inhibits gastric acid via an H(3) receptor pathway. Inflammatory mediators are thus involved in adaptation to the inhibitory effects of H. pylori on acid secretion.

    ABSTRACT: Leptin is a circulating hormone that communicates the peripheral nutritional status to the hypothalamus, which controls food intake, energy expenditure, and body weight. This study characterizes leptin receptors and leptin-sensitive STAT proteins in the antrum and investigates the effects of leptin on gastric secretions. The effects of leptin on gastrin messenger RNA (mRNA), plasma gastrin, gastric acid in vivo in the rat, and on somatostatin and gastrin secretions by isolated antral cells were determined in vitro. Leptin receptors were investigated in isolated rat antral cells by reverse transcription-polymerase chain reaction and binding of [(125)I]-leptin studies. The effects of in vivo and in vitro leptin on transduction signal STAT proteins were investigated by immunoblotting antral extracts. Peripheral injection of leptin inhibited in a dose-dependent manner, basal gastric secretion, gastrinemia, and mucosal gastrin mRNA in vivo. mRNAs encoding the long (Ob-Rb) and short (Ob-Ra) receptor forms were detected in rat antral mucosa, as were STAT-1, -3, and -5b immunoreactive proteins. Isolated antral cells specifically bound [(125)I]-leptin, and addition of leptin to these cells inhibited the release of somatostatin and increased the release of gastrin. These effects were associated with an increase in nuclear STAT-3 proteins in vitro and in vivo. This study provides the first molecular evidence for the coexpression of leptin receptors and STAT-3 in antral mucosa. It provides further evidence for the involvement of leptin in the control of gastric secretions.

    ABSTRACT: We investigated the peripheral effects of an H3-receptor agonist and an H3-receptor antagonist (R)alpha-methylhistamine (Ralpha-MeHA) and thioperamide, respectively, on basal feeding and the CCK8-induced inhibition of food intake in rat. Intraperitoneal injection of thioperamide reduced food intake in a dose-dependent manner with maximal inhibition (35%, P<0.01 vs saline) at 3 mg/kg. (R)alpha-MeHA (0.3-3 mg/kg i.p.), an H3-receptor agonist alone had no effect on feeding but reversed the thioperamide-induced inhibition of food intake in a dose-dependent manner. The maximal feeding inhibitory dose of thioperamide (3 mg.kg i.p) increased by 40% and 22 % (P<0.01 vs saline) brain and stomach histamine contents, respectively. Histamine (0.3 - 6 mg/kg i.p.) and CCK-8 (3 - 30 microg/kg i.p) also inhibited food intake in a dose-dependent manner. Inhibition was 20% to 40% for histamine and 40% to 80% (P<0.01 vs saline) for CCK8. CCK-8 inhibition of feeding was increased by thioperamide and prevented by (R)alpha-MeHA in a dose-dependent way. In addition, CCK-8 did not reduce food intake if rats were pretreated with pyrilamine or ranitidine postsynaptic H1- and H2-receptor antagonists respectively. Our data suggest that the H3-receptor is involved in basal feeding. They also suggest that CCK satiety depends upon the release of histamine which acts on the H2- and H1-receptors, the final mediators of this effect.

    ABSTRACT: The circulating peptide leptin produced by fat cells acts on central receptors to control food intake and body weight homeostasis. Contrary to initial reports, leptin expression has also been detected in the human placenta, muscles, and recently, in rat gastric chief cells. Here we investigate the possible presence of leptin and leptin receptor in the human stomach. Leptin and leptin receptor expression were assessed by immunohistochemistry, reverse transcriptase-polymerase chain reaction (RT-PCR), and western blot analysis on biopsy samples from 24 normal individuals. Fourteen (10 healthy volunteers and four patients with non-ulcer dyspepsia and normal gastric mucosa histology) were analysed for gastric secretions. Plasma and fundic mucosa leptin content was determined by radioimmunoassay. In fundic biopsies from normal individuals, immunoreactive leptin cells were found in the lower half of the fundic glands. mRNA encoding ob protein was detected in the corpus of the human stomach. The amount of fundic leptin was 10.4 (3.7) ng leptin/g mucosa, as determined by radioimmunoassay. Intravenous infusions of pentagastrin or secretin caused an increase in circulating leptin levels and leptin release into the gastric juice. The leptin receptor was present in the basolateral membranes of fundic and antral gastric cells. mRNA encoding Ob-RL was detected in both the corpus and antrum, consistent with a protein of approximately 120 kDa detected by immunoblotting. These data provide the first evidence of the presence of leptin and leptin receptor proteins in the human stomach and suggest that gastric epithelial cells may be direct targets for leptin. Therefore, we conclude that leptin may have a physiological role in the human stomach, although much work is required to establish this.

    ABSTRACT: In the present study, we investigated whether cholecystokinin (CCK) or its structurally related peptide gastrin participates in long term regulation of adipocyte leptin secretion. The levels of circulating leptin observed after 2 and 6 h of refeeding in 18-h fast rats were significantly lowered by injection of the specific gastrin/CCK-B receptor antagonist YM022 at doses that did not affect feeding behavior. Moreover, in normally fed animals, circulating leptin was markedly decreased by chronic injection of YM022 (from 4 +/- 0.6 to 2.1 +/- 0.5 ng/ml). Consistent with these observations, YM022 treatment decreased leptin messenger RNA (mRNA) levels and increased the leptin content in rat epididymal fat tissue. Rat adipocytes exclusively contain gastrin/CCK-B receptor mRNA, but not CCK-A receptor mRNA. Furthermore, adipocyte membranes bound [125I]CCK-8 in a saturable manner, with kinetics consistent with a single class of high affinity sites with a Kd of 0.2 nM. These data argue for a physiological role for the CCK-B/gastrin receptor in adipocyte leptin regulation. We therefore propose that gastrin is involved in long term regulation of leptin expression and secretion in rat fat tissues through activation of an adipocyte gastrin/CCK-B receptor.

    ABSTRACT: The circulating peptide leptin, which is the product of the ob gene, provides feedback information on the size of fat stores to central Ob receptors that control food intake and body-weight homeostasis. Leptin has so far been reported to be secreted only by adipocytes and the placenta. Here we show that leptin messenger RNA and leptin protein are present in rat gastric epithelium, and that cells in the glands of the gastric fundic mucosa are immunoreactive for leptin. The physiological function of this previously unsuspected source of leptin is unknown. However, both feeding and administration of CCK-8 (the biologically active carboxy-terminal end of cholecystokinin) result in a rapid and large decrease in both leptin cell immunoreactivity and the leptin content of the fundic epithelium, with a concomitant increase in the concentration of leptin in the plasma. These results indicate that gastric leptin may be involved in early CCK-mediated effects activated by food intake, possibly including satiety.

    ABSTRACT: We investigated the effects of the novel CCKB/gastrin antagonist YM022 on gastric acid secretion in vivo and in vitro, compared to CI-988 and L365,260 as reference antagonists. In the anaesthetized rat, pentagastrin-induced stimulation of gastric acid secretion was dose-dependently and up to 100% inhibited by i.v. administration of YM022 with an ID50 of 0.009 +/- 0.0006 mumol/kg h in comparison to 0.6 +/- 0.03 and 3.40 +/- 0.05 mumol/kg h for CI-988 and L-365,260, respectively. In the gastric fistula cat, i.v. administration of YM022 produced a similar inhibitory effect with an ID50 of 0.02 mumol/kg in comparison to 1.6 and 2.5 mumol/kg for CI-988 and L-365,260, respectively. Furthermore, bolus injection of 0.6 mumol/kg YM022 produced 100% inhibition within 30 min and 85% inhibition was still observed after 3 h. In the isolated rabbit gastric glands, CCK8-stimulated 14C-aminopyrine uptake was inhibited according to the following rank order of potency: YM022 (IC50 = 0.0012 microM) > > CI-988 (IC50 = 0.2 microM) > > L365,260 (IC50 = 2.8 microM). Unlike with L365,260, no influence of CI-988 and YM022 on histamine-stimulated acid output was shown in this study. Thus, YM022 is a highly potent and selective gastric CCKB/gastrin receptor antagonist and has a long-lasting inhibitory effect on gastric acid secretion.

    ABSTRACT: The beta 3-adrenoceptor (beta 3-AR) agonist SR-58611A {ethyl-[(7s)-7-[[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]5, 6,7,8-tetrahydronaphth-2-yl]oxyacetate hydrochloride} stimulated somatostatin and gastrin releases in isolated rat gastric antral epithelial cells. Stimulation was a concentration-dependent process with 50% effective concentrations of 2.7 +/- 1.1 and 3.8 +/- 1.9 nM compared with 209 +/- 71 and 230 +/- 51 nM for isoproterenol, respectively. It was inhibited by selective beta-AR antagonists with the following rank order of potency: SR-59230A 3-(2-ethylphenoxy)1-[(1S)-1,2,3,4-tetrahydronaphth- 1-ylamino]-(2S)-2-propranol oxalate; beta 3-AR antagonist > ICI-118551[erythro-(+/-)-1-(7-methylindan-4-yloxy)-3- isopropylaminobutan-2-ol-hydrochloride; beta 2-AR antagonist > CGP-20712A[(+/-)-[2-(3-carbarmoyl-4-hydroxyphenoxy)-et hyl- amino]-3-[4 (1-methyl-4-trifluoromethyl-2-imidazolyl)-phenoxy]- 2-propranol; beta 1-AR antagonist]. Furthermore, specific binding of 125I-cyanopindolol to the isolated cells was demonstrated and was displaced by the beta-AR antagonists according to the same rank order of potency and with apparent dissociation constants consistent with the 50% inhibitory concentrations for SR-58611A-stimulated somatostatin and gastrin releases. In addition, the presence of beta 3-AR mRNA was detected by reverse transcriptase polymerase chain reaction. These findings provide the first evidence for a gastric beta 3-AR mediating catecholamine stimulation of gastrin and somatostatin releases from antral cells.

    ABSTRACT: Platelet activating factor (PAF) is a phospholipid mediator known as potent ulcerogenic agent but its physiological role is still unknown in the gastrointestinal tract. Lyso PAF the immediate PAF procursor has no deleterious effect in the gastrointestinal tract. We have previously reported that lyso PAF is produced by gastric mucosa in basal condition and in response to gastrin in healthy men. Helicobacter pylori metabolises lyso PAF to produce PAF. The aim was to study the effect of PAF on the gastric acid secretion. Isolated rabbit glands were used as a model and acid secretion was assessed by (14C) Aminopyrine (AP) uptake. PAF and histamine stimulated AP accumulation time- and dose-dependently. PAF-induced AP accumulation was supressed by omeprazole and Fura 2. BN50727 a specific PAF antagonist inhibited PAF-induced AP accumulation. The presence of a PAF receptor transcript was investigated by reverse transcriptase polymerase chain reaction (RT-PCR) from total mRNA using two primers in which oligonucleotides were synthetized from the human leucocyte PAF receptor cDNA. A single RT-PCR band of the transcript with expected size was detected in the crude isolated cell fraction. These results and others from our laboratory suggest that PAF stimulates gastric acid secretion via specific receptor on the parietal cells and H. pylori produces PAF which may induce mucosal injury directly or indirectly via acid pathway.

    ABSTRACT: In several tissues including gastric mucosa, somatostatin displays various biological effects. Five seven-transmembrane-domain somatostatin receptor subtypes (SSTR1-5) have been recently cloned and only SSTR1 has been shown to be present in the human stomach. We used the polymerase chain reaction on reverse transcripts (RT-PCR) to characterize further the SSTR's mRNAs in human and rat gastric mucosae and in the human gastric tumoral cell-line HGTL. The SSTR1-5's mRNAs were found in both human fundic and antral mucosae as well as in the HGT1 cell and rat antrum. The four SSTR2-5's mRNA's but not SSTR1's were detected in the rat fundic mucosa. Furthermore, the use of rat isolated and purified fundic mucosal cells allowed us to localize SSTR2-5 in the parietal cell-enriched fraction, whereas SSTR2 and SSTR5 were the only subtypes found in the endocrine cell-enriched fraction. These results are the first to demonstrate the presence of five SSTR's mRNA subtypes in the stomach.

    ABSTRACT: The authors have previously reported that platelet-activating factor (PAF), a phospholipid mediator with potent proinflammatory activities, is produced in the gastric mucosa and stimulates gastric acid secretion in humans and animals. In the present study they used the human gastric tumour cells HGT1 (clone 6) to examine whether PAF production is regulated by neuromediators. PAF was extracted by ethanol and assayed by the washed platelet aggregation test. HGT1 cells produced PAF spontaneously (110 +/- 20 pg 10(6) cells). The addition of vasoactive intestinal peptide (VIP; 10(-9) to 10(-7) mol L(-1)) or of histamine (10(-5) to 10(-3) mol L(-1)) increased PAF production by three- to fivefold, while the addition of carbachol (10(-7) to 10(-4) mol L(-1)) increased PAF production up to sevenfold. PAF production was also increased up to 10- to 13-fold, in a dose- and time-dependent manner, by the addition of calcium and two- to threefold by the addition of phorbol myristate acetate (PMA; 10(-7) to 10(-5) mol L(-1)). However, the addition of dibutyryl cyclic AMP (dBcAMP; 10(-6) to 10(-4) mol L(-1) was without any effect. This is the first report showing PAF production by gastric epithelial cells in response to histamine, VIP and carbachol. Furthermore, the findings are consistent with a central role of calcium in this production. The results of this study, together with those of previous studies from the authors' laboratory, support the hypothesis that PAF is a physiological mediator of gastric acid secretion.

    ABSTRACT: We previously reported evidence for H3-receptor inhibition of cholinergic stimulation of acid secretion by isolated rabbit gastric glands. Because this inhibition was unsensitive to H2 antagonists, we postulated that the parietal cell should bear a H3-receptor. In the present study, we investigated the effects of M1-M3 muscarinic receptors antagonists on carbachol- and thioperamide-induced acid secretion (14CAP uptake) by isolated rabbit gastric glands. Furthermore, we examined whether H3-receptor ligands could affect [3H]-N-methylscopolamine binding to the isolated rabbit parietal cells. Both carbachol and thioperamide concentration-dependently stimulated 14CAP uptake in the glands with maximal responses being achieved for 100 microM and 0.1 microM, respectively. These stimulations were concentration-dependently inhibited by the H3-receptor agonists R(alpha)-methylhistamine and imetit. Maximal inhibitions did not exceed 60% for 1 microM. The muscarinic receptor antagonists, hexa-sila-difenidol p-fluoro analog (M3), pirenzepine (M1) and gallamine (M2) inhibited carbachol-induced 14CAP uptake with IC50 of 50 nM, 10 microM and > 100 microM, respectively. Thioperamide-induced 14CAP uptake was also inhibited by hexa-sila-difenidol p-fluoro analog and pirenzepine with IC50 of 90 nM and 12 microM, respectively; whereas gallamine had no effect. [3H]-N-methylscopolamine binding to isolated parietal cells was inhibited by atropine and pFHHSiD with IC50 of 15 nM and 132 nM, respectively. Neither R(alpha)-MeHA nor thioperamide did affect this binding although a H3-receptor inhibitory effect was observed on carbachol-induced 14CAP uptake by the cells. These data support that H3-receptor activation inhibits M3-mediated cholinergic stimulation of acid secretion through mechanisms operating downstream to the receptors sites.

    ABSTRACT: We examined the effect of platelet-activating factor (PAF) on gastric acid secretion by isolated rabbit gastric glands as determined by [14C]aminopyrine ([14C]AP) uptake. PAF, histamine, and carbachol time- and concentration-dependently stimulated [14C]AP uptake, with estimated half-maximal effective concentrations of 60 pM, 0.25 microM, and 0.1 microM, respectively. PAF-induced [14C]AP uptake was inhibited by the specific PAF antagonists BN-50727 and SR-27417 and by the proton pump inhibitors omeprazole and lansoprazole. However, the H2-receptor antagonist famotidine had no effect. Buffering extracellular Ca2+ by ethylene glycol-bis(beta-amino-ethyl ether)-N,N,N',N'-tetraacetic acid resulted in a shift to the right of the time-course effect of PAF without altering the maximal response, whereas buffering intracellular Ca2+ by 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid 2-acetoxymethyl ester, as well as blocking Ca2+ channels by verapamil, inhibited PAF-induced [14C]AP uptake. Intracellular Ca2+ concentration in isolated rabbit gastric glands, as measured by fura 2-acetoxymethyl ester, concentration-dependently increased in response to PAF, to a maximum of 1.5-fold for 0.1 microM. These results suggest that PAF stimulates gastric acid secretion via specific receptors activating intracellular Ca2+ mobilization, which could be located on the parietal cells.
