Abstract
Gastric ulcers affect approx. 10% of population. Non-steroidal anti-inflammatory drugs (NSAIDs), including acetylsalicylic acid (ASA) predispose to or impair the physiologically complex healing of pre-existing ulcers. Since H2S is an endogenous cytoprotective molecule, we hypothesized that new H2S-releasing ASA-derivative (ATB-340) could overcome pathological impact of NSAIDs on GI regeneration.Clinically translational gastric ulcers were induced in Wistar rats using state-of-the-art microsurgical model employing serosal application of acetic acid. This was followed by 9 days long i.g. daily treatment with vehicle, ATB-340 (6-24 mg/kg) or equimolar ASA doses (4-14 mg/kg). Ulcer area was assessed macro- and microscopically. Prostaglandin (PG)E2 levels, indicating pharmacological activity of NSAIDs and 8-hydroxyguanozine content, reflecting nucleic acids oxidation in serum/gastric mucosa, were determined by ELISA. Qualitative and/or quantitative pathway-specific alterations at the ulcer margin were evaluated using real-time PCR and mass spectrometry-based proteomics.ASA, unlike ATB-340, dose-dependently delayed/impaired gastric tissue recovery, deregulating 310 proteins at the ulcer margin, including Ras signalling, wound healing or apoptosis regulators. ATB-340 maintained NSAIDs-specific cyclooxygenase-inhibiting capacity on systemic and GI level but in time-dependent manner. High dose of ATB-340 (24 mg/kg daily), but not ASA, decreased nucleic acids oxidation and upregulated anti-oxidative/anti-inflammatory heme oxygenase-1, 24-dehydrocholesterol reductase or suppressor of cytokine signalling (SOCS3) at the ulcer margin.Thus, ASA impairs the physiological healing of pre-existing gastric ulcers, inducing the extensive molecularly functional and proteomic alterations at the wound margin. H2S-releasing ATB-340 maintains the target activity of NSAIDs with limited impact on gastric PGE2 signalling and physiological GI regeneration, enhancing anti-inflammatory and anti-oxidative response, and providing the pharmacological advantage.

Abstract
The gut mucosal barrier plays a key role in the physiology of gastrointestinal (GI) tract, preventing under homeostatic conditions, the epithelial cells of the gastric mucosa from hydrochloric acid and intestinal mucosa from alkaline secretion, food toxins and pathogenic microbiota. Previous studies have documented that blockade of both isoforms of cyclooxygenase (COX): constitutive (COX-1) and inducible (COX-2), as well NO synthase in the stomach exacerbated the gastric damage induced by various ulcerogens, however, such as effects of non-selective and selective inhibition of COX-1, COX-2 and NOS enzymes on colonic damage have been little studied. The supplementation of NO by intragastric (i.g.) treatment with NO-releasing compound NO-aspirin (NO-ASA) or substrate for NO synthase L-arginine ameliorated the damage of upper GI-tract, but whether similar effect can be observed in colonic mucosa associated with the experimental colitis, and if above mentioned compounds can be effective in aggravation or protection of experimental colitis remains less recognized. In this study rats with experimental colitis induced by intrarectal administration of 2,4,6-trinitrobenzosulphonic acid (TNBS) were daily treated for 7 days with: 1) vehicle (i.g.), 2) ASA 40 mg/kg (i.g.), 3) rofecoxib 10 mg/kg (i.g.), 4) resveratrol 10 mg/kg (i.g.), 5) NO-ASA 40 mg/kg (i.g.), 6) L-arginine 200 mg/kg (i.g.) with or without of L-NNA 20 mg/kg (i.p.). The macroscopic and microscopic area of colonic damage was determined planimetrically, the colonic blood flow (CBF) was assessed by Laser flowmetry, and the oxidative stress biomarkers malondialdehyde and 4-hydroxynonenal (MDA+4-HNE), the antioxidative factors superoxide dismutase (SOD) and glutathione (GSH), as well as proinflammatory cytokines in the colonic mucosa (tumor necrosis factor alpha (TNF-α) and interleukin-1beta (IL-1β)) were measured. We have documented that administration of TNBS produced gross and microscopic colonic damage and significantly decreased CBF (p<0.05). Treatment with ASA significantly increased the area of colonic damage (p<0.05), an effect accompanied by a significant decrease in the CBF, the significant increment of MDA+4-HNE, and the attenuation of the antioxidative properties in colonic mucosa, documented by a significant decrease of SOD activity and GSH concentration, and elevation of the colonic tissue levels of TNF-α and IL-1β comparing to control Veh-treated TNBS rats. Administration of rofecoxib or resveratrol also significantly increased the colonic damage and significantly decreased the CBF, causing an increase in MDA+4-HNE and mucosal content of TNF-α and IL-1α and a significant decrease of the SOD activity and GSH content (p<0.05), however, these changes were significantly less pronounced as compared with ASA. On the contrary, the treatment with NO-ASA, or L-arginine, significantly diminished the area of colonic lesions, the MDA+4-HNE concentration, attenuated the TNF-α and IL-1β levels, while increasing the CBF, SOD activity and GSH content (p<0.05). The concomitant treatment of L-NNA with rofecoxib or resveratrol reversed an increase in area of colonic damage and accompanying changes in CBF, colonic mucosa TNF-α and IL-1β levels, the MDA+4-HNE concentration, and SOD activity and GSH content comparing to those observed in TNBS rats treated with these COX-inhibitors alone (p<0.05). In contrast, co-treatment with L-NNA and NO-ASA or L-arginine failed to significantly affect the decrease of colonic lesions accompanied by the rise in CBF, the attenuation of MDA+4-HNE concentration, TNF-α and IL-1β levels, SOD activity and GSH content exerted by NO-ASA- or L-arginine treatment of the respective control TNBS-rats without L-NNA administration. These observations suggest that 1) the increase of NO availability either from NO-releasing donors such as NO-ASA or NO precursors such as L-arginine, can inhibit the inflammatory and microvasculature alterations, as well as increase in lipid peroxidation due to the enhanced efficacy of these compounds to increase the antioxidative properties of colonic mucosa, 2) unlike ASA which exacerbated the severity of colitis, the treatment with rofecoxib, the specific 'safer' COX-2 inhibitor or resveratrol, the polyphenolic compound known to act as the dual COX-1 and COX-2 inhibitor, can attenuate the colonic damage during course of TNBS colitis possibly via anti-inflammatory and antioxidative properties, and 3) the blockade of endogenous NO activity by L-NNA which also exacerbated the severity of mucosal damage in colitis, can abolish the sparing effect of rofecoxib and resveratrol indicating the NO bioavailability plays an important role in enhanced efficacy of both specific and dual COX inhibitors to ameliorate the experimental colitis.

Abstract
Hydrogen sulfide (H2S) signaling and H2S-prodrugs maintain redox balance in gastrointestinal (GI) tract. Predominant effect of any H2S-donor is mitochondrial. Non-targeted H2S-moieties were shown to decrease the non-steroidal anti-inflammatory drugs (NSAIDs)-induced gastrotoxicity but in high doses. However, direct, controlled delivery of H2S to gastric mucosal mitochondria as a molecular target improving NSAIDs-pharmacology remains overlooked. Thus, we treated Wistar rats, i.g. with vehicle, mitochondria-targeted H2S-releasing AP39 (0.004-0.5 mg/kg), AP219 (0.02 mg/kg) as structural control without H2S-releasing ability, or AP39 + SnPP (10 mg/kg) as a heme oxygenase (HMOX) inhibitor. Next, animals were administered i.g. with acetylsalicylic acid (ASA, 125 mg/kg) as NSAIDs representative or comparatively with 75% ethanol to induce translational hemorrhagic or necrotic gastric lesions, that were assessed micro-/macroscopically. Activity of mitochondrial complex IV/V, and DNA oxidation were assessed biochemically. Gastric mucosal/serum content of IL-1β, IL-10, TNF-α, TGF-β1/2, ARG1, GST-α, or phosphorylation of mTOR, NF-κB, ERK, Akt, JNK, STAT3/5 were evaluated by microbeads-fluorescent xMAP®-assay; gastric mucosal mRNA level of HMOX-1/2, COX-1/2, SOD-1/2 by real-time PCR. AP39 (but not AP219) dose-dependently (0.02 and 0.1 mg/kg) diminished NSAID- (and ethanol)-induced gastric lesions and DNA oxidation, restoring mitochondrial complexes activity, ARG1, GST-α protein levels and increasing HMOX-1 and SOD-2 expression. AP39 decreased proteins levels or phosphorylation of gastric mucosal inflammation/oxidation-sensitive markers and restored mTOR phosphorylation. Pharmacological inhibition of HMOX-1 attenuated AP39-gastroprotection. We showed that mitochondria-targeted H2S released from very low i.g. doses of AP39 improved gastric mucosal capacity to cope with NSAIDs-induced mitochondrial dysfunction and redox imbalance, mechanistically requiring the activity of HMOX-1.

Abstract
Hydrogen sulfide (H2S) emerged recently as an anti-oxidative signaling molecule that contributes to gastrointestinal (GI) mucosal defense and repair. Indomethacin belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs) and is used as an effective intervention in the treatment of gout- or osteoarthritis-related inflammation. However, its clinical use is strongly limited since indomethacin inhibits gastric mucosal prostaglandin (PG) biosynthesis, predisposing to or even inducing ulcerogenesis. The H2S moiety was shown to decrease the GI toxicity of some NSAIDs. However, the GI safety and anti-oxidative effect of a novel H2S-releasing indomethacin derivative (ATB-344) remain unexplored. Thus, we aimed here to compare the impact of ATB-344 and classic indomethacin on gastric mucosal integrity and their ability to counteract the development of oxidative gastric mucosal injuries. Wistar rats were pretreated intragastrically (i.g.) with vehicle, ATB-344 (7-28 mg/kg i.g.), or indomethacin (5-20 mg/kg i.g.). Next, animals were exposed to microsurgical gastric ischemia-reperfusion (I/R). Gastric damage was assessed micro- and macroscopically. The volatile H2S level was assessed in the gastric mucosa using the modified methylene blue method. Serum and gastric mucosal PGE2 and 8-hydroxyguanozine (8-OHG) concentrations were evaluated by ELISA. Molecular alterations for gastric mucosal barrier-specific targets such as cyclooxygenase-1 (COX)-1, COX-2, heme oxygenase-1 (HMOX)-1, HMOX-2, superoxide dismutase-1 (SOD)-1, SOD-2, hypoxia inducible factor (HIF)-1α, xanthine oxidase (XDH), suppressor of cytokine signaling 3 (SOCS3), CCAAT enhancer binding protein (C/EBP), annexin A1 (ANXA1), interleukin 1 beta (IL-1β), interleukin 1 receptor type I (IL-1R1), interleukin 1 receptor type II (IL-1R2), inducible nitric oxide synthase (iNOS), tumor necrosis factor receptor 2 (TNFR2), or H2S-producing enzymes, cystathionine γ-lyase (CTH), cystathionine β-synthase (CBS), or 3-mercaptopyruvate sulfur transferase (MPST), were assessed at the mRNA level by real-time PCR. ATB-344 (7 mg/kg i.g.) reduced the area of gastric I/R injuries in contrast to an equimolar dose of indomethacin. ATB-344 increased gastric H2S production, did not affect gastric mucosal PGE2 content, prevented RNA oxidation, and maintained or enhanced the expression of oxidation-sensitive HMOX-1 and SOD-2 in line with decreased IL-1β and XDH. We conclude that due to the H2S-releasing ability, i.g., treatment with ATB-344 not only exerts dose-dependent GI safety but even enhances gastric mucosal barrier capacity to counteract acute oxidative injury development when applied at a low dose of 7 mg/kg, in contrast to classic indomethacin. ATB-344 (7 mg/kg) inhibited COX activity on a systemic level but did not affect cytoprotective PGE2 content in the gastric mucosa and, as a result, evoked gastroprotection against oxidative damage.

Abstract
Hydrogen sulfide (H2S) as a gaseous molecule prevents gastrointestinal (GI)-tract against various injuries. This study aimed to evaluate for the first time the detailed molecular mechanism of mitochondria-targeting H2S-prodrugs, AP39 and RT01 in gastroprotection against ischemia/reperfusion (I/R)-induced lesions. Wistar rats exposed to I/R were pretreated i.g. with vehicle, AP39 (0.004-2 mg/kg), RT01 (0.1 mg/kg), or with AP219 (0.1 mg/kg) as structural control without ability to release H2S. AP39 was also administered with mTOR1 inhibitor, rapamycin (1 mg/kg i.g.). Gastric damage area was assessed micro-/macroscopically, gastric blood flow (GBF) by laser flowmetry, mRNA level of HIF-1α, GPx, SOD1, SOD2, annexin-A1, SOCS3, IL-1RA, IL-1β, IL-1R1, IL-1R2, TNFR2, iNOS by real-time PCR. Gastric mucosal and/or serum content of IL-1β, IL-4, IL-5, IL-10, G-CSF, M-CSF, VEGFA, GRO, RANTES, MIP-1α, MCP1, TNF-α, TIMP1, FABP3, GST-α, STAT3/5 and phosphorylation of mTOR, NF-κB, ERK, Akt was evaluated by microbeads-fluorescent assay. Mitochondrial complexes activities were measured biochemically. RNA damage was assessed as 8-OHG by ELISA. AP39 and RT01 reduced micro-/macroscopic gastric I/R-injury increasing GBF. AP39-gastroprotection was accompanied by maintained activity of mitochondrial complexes, prevented RNA oxidation and enhanced mRNA/protein expression of SOCS3, IL-1RA, annexin-A1, GST-α, HIF-1α. Rapamycin reversed AP-39-gastroprotection. AP39-gastroprotection was followed by decreased NF-κB, ERK, IL-1β and enhanced Akt and mTOR proteins phosphorylation. AP39-prevented gastric mucosal damage caused by I/R-injury, partly by mitochondrial complex activity maintenance. AP39-mediated attenuation of gastric mucosal oxidation, hypoxia and inflammation involved mTOR1 and Akt pathways activity and modulation of HIF-1α, GST-α, SOCS3, IL1RA and TIMP1 molecular interplay.

Abstract
Obesity may be treated by bariatric procedures and is related to enterohormone release modulation. Nevertheless, a majority of commonly used surgical procedures have a significant impact on vagus nerve function by breaking the connections with its gastric branches. In the case of an intragastric balloon (BAL), this interaction is unclear. However, BAL-induced weight reduction is not long-lasting. Interestingly, this method has not been used in combination with vagotomy (VAG). Thus, we evaluated, for the first time, the short- and long-term effects of combined BAL and VAG using the animal-based translational model and compared these effects with sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). Wistar rats were fed a high-calorie diet for 8 weeks to induce obesity before SG, RYGB, BAL + / - VAG. Animals' weight and eating behaviors were monitored weekly. After 90 days, serum samples were collected to evaluate postprandial and fasting GLP-1, GIP, PYY, ghrelin, glucagon, insulin, leptin, and pancreatic polypeptide concentrations by fluorescent assay. VAG, SG, RYGB, and BAL + VAG significantly reduced body weight 30 and 90 days after surgery. BAL alone induced temporal weight reduction observed after 30 days, reversed after 90 days. Calories intake was reduced at the first half of the observation period in all groups. Fluid intake was reduced in all groups except SG and BAL. Enterohormone profile for BAL + VAG was comparable to SG and RYGB but not BAL. VAG and BAL + VAG but not BAL alone maintain weight reduction, alimentary intake changes, and enterohormone release after long-term observation. VAG may improve the effectiveness of bariatric procedures for obesity treatment in clinical practice.

Abstract
Aims: Nonsteroidal anti-inflammatory drugs, including ketoprofen, induce adverse effects within the gastrointestinal (GI)-tract. Hydrogen sulfide (H2S) is an antioxidative gaseous mediator contributing to GI-protection. We aimed to evaluate the GI safety of a novel H2S-releasing derivative of ketoprofen (ATB-352) versus classic ketoprofen and the molecular mechanisms of their activity after chronic treatment in experimental animal models. Results: Ketoprofen (10 mg/kg/day) administered intragastrically for 7 days in contrast with ATB-352 (14 mg/kg/day) reduced mucosal H2S content inducing GI damage with significantly increased injury score, altered intestinal microbiome profile, and modulation of more than 50% of 36 investigated molecular sensors (e.g., mammalian target of rapamycin or suppressor of cytokine signaling 3 [SOCS3]). Polypharmacy with aspirin (10 mg/kg/day) enhanced ketoprofen toxicity not affecting GI safety of ATB-352. Omeprazole (20 mg/kg/day) decreased ketoprofen-induced injury to the level of ATB-352 alone. Both compounds combined or not with aspirin or omeprazole maintained the ability to inhibit cyclooxygenase (COX) activity manifested by decreased prostaglandin production. Innovation and Conclusions: Ketoprofen-induced H2S-production decrease and intestinal microbiome profile alterations lead to GI toxicity observed on macro-/microscopic and molecular levels. Ketoprofen but not ATB-352 requires concomitant treatment with omeprazole to eliminate GI adverse effects. ATB-352 applied alone or in a polypharmacy setting with aspirin effectively inhibited COX and maintained GI safety due to H2S-release. Neither compound affected DNA oxidation in the GI mucosa, but ATB-352 had lower impact on molecular oxidative/inflammatory response pathways and intestinal microbiome. The GI safety of ATB-352 could be due to the involvement of heme oxygenase 1 and SOCS3 pathway activation. Antioxid. Redox Signal. 36, 189-210.

Abstract
Hydrogen sulfide (H2S) is an endogenously produced molecule with anti-inflammatory and cytoprotective properties. We aimed to investigate for the first time if a novel, esterase-sensitive H2S-prodrug, BW-HS-101 with the ability to release H2S in a controllable manner, prevents gastric mucosa against acetylsalicylic acid-induced gastropathy on microscopic and molecular levels. Wistar rats were pretreated intragastrically with vehicle, BW-HS-101 (0.5-50 μmol/kg) or its analogue without the ability to release H2S, BW-iHS-101 prior to ASA administration (125 mg/kg, intragastrically). BW-HS-101 was administered alone or in combination with nitroarginine (L-NNA, 20 mg/kg, intraperitoneally) or zinc protoporphyrin IX (10 mg/kg, intraperitoneally). Gastroprotective effects of BW-HS-101 were additionally evaluated against necrotic damage induced by intragastrical administration of 75% ethanol. Gastric mucosal damage was assessed microscopically, and gastric blood flow was determined by laser flowmetry. Gastric mucosal DNA oxidation and PGE2 concentration were assessed by ELISA. Serum and/or gastric protein concentrations of IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-10, IL-13, VEGF, GM-CSF, IFN-γ, TNF-α, and EGF were determined by a microbeads/fluorescent-based multiplex assay. Changes in gastric mucosal iNOS, HMOX-1, SOCS3, IL1-R1, IL1-R2, TNF-R2, COX-1, and COX-2 mRNA were assessed by real-time PCR. BW-HS-101 or BW-iHS-101 applied at a dose of 50 μmol/kg protected gastric mucosa against ASA-induced gastric damage and prevented a decrease in the gastric blood flow level. H2S prodrug decreased DNA oxidation, systemic and gastric mucosal inflammation with accompanied upregulation of SOCS3, and EGF and HMOX-1 expression. Pharmacological inhibition of nitric oxide (NO) synthase but not carbon monoxide (CO)/heme oxygenase (HMOX) activity by L-NNA or ZnPP, respectively, reversed the gastroprotective effect of BW-HS-101. BW-HS-101 also protected against ethanol-induced gastric injury formation. We conclude that BW-HS-101, due to its ability to release H2S in a controllable manner, prevents gastric mucosa against drugs-induced gastropathy, inflammation and DNA oxidation, and upregulate gastric microcirculation. Gastroprotective effects of this H2S prodrug involves endogenous NO but not CO activity and could be mediated by cytoprotective and anti-inflammatory SOCS3 and EGF pathways.

Abstract
Metal-based carbon monoxide (CO)-releasing molecules have been shown to exert anti-inflammatory and anti-oxidative properties maintaining gastric mucosal integrity. We are interested in further development of metal-free CO-based therapeutics for oral administration. Thus, we examine the protective effect of representative CO prodrug, BW-CO-111, in rat models of gastric damage induced by necrotic ethanol or aspirin, a representative non-steroidal anti-inflammatory drug. Treatment effectiveness was assessed by measuring the microscopic/macroscopic gastric damage area and gastric blood flow by laser flowmetry. Gastric mucosal mRNA and/or protein expressions of HMOX1, HMOX2, nuclear factor erythroid 2-related factor 2, COX1, COX2, iNos, Anxa1 and serum contents of TGFB1, TGFB2, IL1B, IL2, IL4, IL5, IL6, IL10, IL12, tumor necrosis factor α, interferon γ, and GM-CSF were determined. CO content in gastric mucosa was assessed by gas chromatography. Pretreatment with BW-CO-111 (0.1 mg/kg, i.g.) increased gastric mucosal content of CO and reduced gastric lesions area in both models followed by increased GBF. These protective effects of the CO prodrug were supported by changes in expressions of molecular biomarkers. However, because the pathomechanisms of gastric damage differ between topical administration of ethanol and aspirin, the possible protective and anti-inflammatory mechanisms of BW-CO-111 may be somewhat different in these models.

Abstract
Gut-brain axis plays a central role in the regulation of stress related diseases such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD). It is increasingly recognized that stress modulates gut microbiota community structure and activity and represents an important causal factor in dysbiosis. This study was designed to determine the effect of daily treatment with synbiotic (Syngut) containing inulin, Lactobacillus acidophilus, Bifidobacterium lactis W51, Lactobacillus plantarum W21 and Lactococcus lactis applied i.g. at a dose of 50 mg/kg i.g. on the colonic damage and colonic mucosal blood flow in rats with experimentally induced TNBS-colitis that were additionally exposed or not to acute stress (episodes of cold restraint stress every other day before colitis induction). Control rats received daily treatment with vehicle (saline, i.g.) or mesalazine (50 mg/kg-d i.g.), the standard drug recommended in therapy of IBD. At the termination of TNBS colitis, the histologic evaluation of colonic mucosa, mucosal malonyldialdehyde (MDA) level and plasma concentrations of proinflammatory cytokines (TNF-α, IL-1β) and adipokine adiponectin were assessed. the samples of colonic mucosa not involving colonic lesions and surrounding the flared mucosa were excised for the determination of mRNA expression for proinflammatory biomarkers TNF-α, IL-1β, IL-10 and COX-2 as well as antioxidazing factors SOD-1 and SOD-2. Finally, the gut microbial profiles were analyzed by 16S rRNA sequencing at phylum, family and genus level. Episodes of cold stress significantly aggravated the course of TNBS colitis, and significantly increased the release of proinflammatory cytokines as well as the significant increase in the MDA concentration has been observed as compared with non-stressed TNBS rats. These changes were followed by the significant fall in the CBF and plasma adiponectin levels and by the overexpression of mRNA of proinflammatory biomarkers. Synbiotic treatment with Syngut significantly reduced the area of colonic lesions observed macroscopically and microscopically in rats with TNBS colitis with or without exposure to cold stress, significantly increased the CBF, normalized plasma adiponectin levels and significantly attenuated the release and colonic expression of proinflammatory cytokines and biomarkers. the analysis of the gut microbiota showed a significant reduction of microbial diversity (Shannon index) in rats with TNBS colitis with or without exposure to stress. The therapy with Syngut failed to significantly affect the alpha diversity. At the phylum level, the significant rise in Proteobacteria has been observed in stressed rats with TNBS colitis and this effects was attenuated by treatment with Syngut. At family level, TNBS colitis alone or in combination with stress led to a significant decrease of SCFA producing bacterial taxa such as Ruminococaceae and Lachnospiraceae and Syngut counteracted this effect. We conclude that: 1) cold stress exacerbates the gastrointestinal inflammation in experimental colitis; 2) the synbiotic therapy with Syngut ameliorates the gut inflammation in rats with TNBS colitis combined with cold stress; 3) the beneficial effect of Syngut is accompanied by increase of anti-inflammatory taxa such as Ruminococaceae and Lachnospiraceae, and 4) the modulation of gut microbiota with Syngut alleviates stress-related intestinal inflammation suggesting a potential usefulness of synbiotic therapy in intestinal disorders accompanied by stress in patients with IBD.

Abstract
Inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease, are multifactorial, chronic, disabling, and progressive diseases characterised by cyclical nature, alternating between active and quiescent states. While the aetiology of IBD is not fully understood, this complex of diseases involve a combination of factors including the genetic predisposition and changes in microbiome as well as environmental risk factors such as high-fat and low-fibre diets, reduced physical activity, air pollution and exposure to various toxins and drugs such as antibiotics. The prevalence of both IBD and obesity is increasing in parallel, undoubtedly proving the existing interactions between these risk factors common to both disorders to unravel poorly recognized cell signaling and molecular alterations leading to human IBD. Therefore, there is still a significant and unmet need for supportive and adjunctive therapy for IBD patients directed against the negative consequences of visceral obesity and bacterial dysbiosis. Among the alternative therapies, a moderate-intensity exercise can benefit the health and well-being of IBD patients and improve both the healing of human IBD and experimental animal colitis. Intestinal alkaline phosphatase (IAP) plays an essential role in the maintenance of intestinal homeostasis intestinal and the mechanism of mucosal defence. The administration of exogenous IAP could be recommended as a therapeutic strategy for the cure of diseases resulting from the intestinal barrier dysfunction such as IBD. Curcumin, a natural anti-inflammatory agent, which is capable of stimulating the synthesis of endogenous IAP, represents another alternative approach in the treatment of IBD. This review was designed to discuss potential “nonpharmacological” alternative and supplementary therapeutic approaches taking into account epidemiological and pathophysiological links between obesity and IBD, including changes in the functional parameters of the intestinal mucosa and alterations in the intestinal microbiome.

Abstract
Exposure to acidic gastric content due to malfunction of lower esophageal sphincter leads to acute reflux esophagitis (RE) leading to disruption of esophageal epithelial cells. Carbon monoxide (CO) produced by heme oxygenase (HMOX) activity or released from its donor, tricarbonyldichlororuthenium (II) dimer (CORM-2) was reported to protect gastric mucosa against acid-dependent non-steroidal anti-inflammatory drug-induced damage. Thus, we aimed to investigate if CO affects RE-induced esophageal epithelium lesions development. RE induced in Wistar rats by the ligation of a junction between pylorus and forestomach were pretreated i.g. with vehicle CORM-2; RuCl3; zinc protoporphyrin IX, or hemin. CORM-2 was combined with NG-nitro-L-arginine (L-NNA), indomethacin, capsazepine, or capsaicin-induced sensory nerve ablation. Esophageal lesion score (ELS), esophageal blood flow (EBF), and mucus production were determined by planimetry, laser flowmetry, histology. Esophageal Nrf-2, HMOXs, COXs, NOSs, TNF-α and its receptor, IL-1 family and IL-1 receptor antagonist (RA), NF-κB, HIF-1α, annexin-A1, suppressor of cytokine signaling (SOCS3), TRPV1, c-Jun, c-Fos mRNA/protein expressions, PGE2, 8-hydroxy-deoxyguanozine (8-OHdG) and serum COHb, TGF-β1, TGF-β2, IL-1β, and IL-6 content were assessed by PCR, immunoblotting, immunohistochemistry, gas chromatography, ELISA or Luminex platform. Hemin or CORM-2 alone or combined with L-NNA or indomethacin decreased ELS. Capsazepine or capsaicin-induced denervation reversed CORM-2 effects. COHb blood content, esophageal HMOX-1, Nrf-2, TRPV1 protein, annexin-A1, HIF-1α, IL-1 family, NF-κB, c-Jun, c-Fos, SOCS3 mRNA expressions, and 8-OHdG levels were elevated while PGE2 concentration was decreased after RE. CO donor-maintained elevated mucosal TRPV1 protein, HIF-1 α, annexin-A1, IL-1RA, SOCS3 mRNA expression, or TGF-β serum content, decreasing 8-OHdG level, and particular inflammatory markers expression/concentration. CORM-2 and Nrf-2/HMOX-1/CO pathway prevent esophageal mucosa against RE-induced lesions, DNA oxidation, and inflammatory response involving HIF-1α, annexin-A1, SOCS3, IL-1RA, TGF-β-modulated pathways. Esophagoprotective and hyperemic CO effects are in part mediated by afferent sensory neurons and TRPV1 receptors activity with questionable COX/PGE2 or NO/NOS systems involvement.

Abstract
Mixed acidic-alkaline refluxate is a major pathogenic factor in chronic esophagitis progressing to Barrett's esophagus (BE). We hypothesized that epidermal growth factor (EGF) can interact with COX-2 and peroxisome proliferator-activated receptor-γ (PPARγ) in rats surgically prepared with esophagogastroduodenal anastomosis (EGDA) with healthy or removed salivary glands to deplete salivary EGF. EGDA rats were treated with 1) vehicle, 2) EGF or PPARγ agonist pioglitazone with or without EGFR kinase inhibitor tyrphostin A46, EGF or PPARγ antagonist GW9662 respectively, 3) ranitidine or pantoprazole, and 4) the selective COX-2 inhibitor celecoxib combined with pioglitazone. At 3 mo, the esophageal damage and the esophageal blood flow (EBF) were determined, the mucosal expression of EGF, EGFR, COX-2, TNFα, and PPARγ mRNA and phospho-EGFR/EGFR protein was analyzed. All EGDA rats developed chronic esophagitis, esophageal ulcerations, and intestinal metaplasia followed by a fall in the EBF, an increase in the plasma of IL-1β, TNFα, and mucosal PGE2 content, the overexpression of COX-2-, and EGF-EGFR mRNAs, and proteins, and these effects were aggravated by EGF and attenuated by pioglitazone. The rise in EGF and COX-2 mRNA was inhibited by pioglitazone but reversed by pioglitazone cotreated with GW9662. We conclude that 1) EGF can interact with PG/COX-2 and the PPARγ system in the mechanism of chronic esophagitis; 2) the deleterious effect of EGF involves an impairment of EBF and the overexpression of COX-2 and EGFR, and 3) agonists of PPARγ and inhibitors of EGFR may be useful in the treatment of chronic esophagitis progressing to BE.NEW & NOTEWORTHY Rats with EGDA exhibited chronic esophagitis accompanied by a fall in EBF and an increase in mucosal expression of mRNAs for EGF, COX-2, and TNFα, and these effects were exacerbated by exogenous EGF and reduced by removal of a major source of endogenous EGF with salivectomy or concurrent treatment with tyrphostin A46 or pioglitazone combined with EGF. Beneficial effects of salivectomy in an experimental model of BE were counteracted by PPARγ antagonist, whereas selective COX-2 inhibitor celecoxib synergistically with pioglitazone reduced severity of esophageal damage and protected esophageal mucosa from reflux. We propose the cross talk among EGF/EGFR, PG/COX-2, and proinflammatory cytokines with PPARγ pathway in the mechanism of pathogenesis of chronic esophagitis progressing to BE and EAC.

Abstract
Cancer-associated RNF43 mutations lead to activation of β-catenin signaling through aberrantly increasing Wnt-receptor levels at the membrane. Importantly, inactivating RNF43 mutations have been suggested to render cancer cells sensitive to Wnt-based therapeutics. However, the extent to which RNF43 mutations lead to impaired regulation of Wnt/β-catenin signaling has been poorly investigated. Here, we observed that tumors with a functional mismatch repair system show a predominant 5'-location of truncating RNF43 mutations, suggesting C-terminal truncations such as the most commonly reported p.G659fs mutation, do not affect β-catenin signaling. In accordance, expressing C-terminal truncation mutants and wild-type RNF43, showed equal effects on β-catenin signaling, Wnt-receptor turnover, and DVL-binding. We confirmed these observations at endogenous levels by CRISPR-Cas9-mediated knockout of G659fs RNF43 expression in KM12 cells and generating comparable mutations in HEK293T cells. We could not confirm previous reports linking RNF43 to p53 and E-cadherin breakdown. Our data also suggest that only colorectal cancer cells harboring N-terminal mutations of RNF43 convey Wnt-dependency onto the tumor cells. Results of this study have potentially important clinical implications indicating that Wnt-based therapeutics should be applied cautiously in cancer patients harboring RNF43 mutations.

Abstract
Endogenous gaseous mediators, such as nitric oxide, hydrogen sulfide or carbon monoxide (CO) are known to exert anti-inflammatory and anti-oxidative activity due to modulation of various molecular pahtways. Therefore, we aimed to investigate if CO released from tricarbonyldichlororuthenium (II) dimer (CORM-2) prevents gastric mucosa against ischemia/reperfusion (I/R)-induced injury in male Wistar rats. Animals were pretreated i.g. With vehicle (DMSO and saline, 1:10), CORM-2 (1, 5 or 10 mg/kg) or zinc protoporphyrin IX (ZnPP, 10 mg/kg i.p.), the HMOXs inhibitor. In separate series, rats were pretreated with CORM-2 (5 mg/kg) applied in combination with glibenclamide (10 mg/kg i.g.), NG-nitro-l-arginine (L-NNA, 20 mg/kg i.p.), 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 10 mg/kg i.p.) or indomethacin (5 mg/kg i.p.). I/R-injuries were induced by clamping celiac artery for 30 min (I) followed by removal of the clamp to obtain R for 3 h. The macroscopic and microscopic area of gastric damage, mucus production and protein expression for HMOX-1/Nrf-2 was determined by planimetry, histology and immunohistochemistry, respectively. Gastric mucosal HMOX-1, HMOX-2, COX-1, COX-2, Kir6.1, Sur2, sGC-α1, sGC-α2, iNOS and eNOS mRNA expression was assessed by real-time PCR. COHb in blood and gastric mucosal CO concentration was analyzed by gas chromatography. Serum content of TGF-β1, TGF-β2, TGF-β3, IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, TNF-α, IFN-γ, GM-CSF was evaluated using Luminex platform. PGE2 concentration and 8-hydroxyguanozine (8-OHG) concentration in gastric mucosa was determined by ELISA. Exposure to I/R induced extensive hemorrhagic erosions in gastric mucosa pretreated with vehicle as compared with intact rats and the area of this gastric damage was reduced by pretreatment with CORM-2 (5 mg/kg i.g.). This effect of CO donor was accompanied by the increased PGE2 content and a significant decrease in 8-OHG and expression of pro- and anti-inflammatory markers mRNA and proteins. Concurrent treatment of CORM-2 with glibenclamide, L-NNA, ODQ but not with indomethacin significantly increased the area of I/R-induced injury and significantly decreased GBF as compared with the group treated with CORM-2 alone. We conclude that CO releasing CORM-2 prevents gastric mucosal oxidative damage induced by I/R improving GBF, decreasing DNA oxidation and inflammatory response on systemic level. This CO-gastroprotection is mediated by the activity of sGC, NOS and K-ATP channels. CO delivered from its donor maintained physiological gastric mucosal PGE2 concentration but the involvement of endogenous COX in beneficial activity of this gaseous mediator at least in this model is questionable.

Abstract
BACKGROUND Physical activity can be involved in the prevention of gastrointestinal (GI)-tract diseases, however, the results regarding the volume and the intensity of exercise considered as beneficial for protection of gastrointestinal organs are conflicting. AIMS AND METHODS The main objective of this review is to provide a comprehensive and updated overview on the beneficial and harmful effects of physical activity on the gastrointestinal tract. We attempted to discuss recent evidence regarding the association between different modes and intensity levels of exercise and physiological functions of the gut and gut pathology. RESULTS The regular, moderate exercise can exert a beneficial effect on GI-tract disorders such as reflux esophagitis, peptic ulcers, cholelithiasis, constipation and Inflammatory Bowel Disease (IBD) leading to the attenuation of the symptoms. This voluntary exercise has been shown to reduce the risk of colorectal cancer. On the other hand, there is considerable evidence that the high-intensity training or prolonged endurance training can exert a negative influence on GI-tract resulting in the exacerbation of symptoms. CONCLUSION Physical activity can exhibit a beneficial effect on a variety of gastrointestinal diseases, however, this effect depends upon the exercise mode, duration and intensity. The accumulated evidence indicate that management of gastrointestinal problems and their relief by the exercise seems to be complicated and require adjustments of physical activity training, dietary measures and medical monitoring of symptoms. More experimental and clinical studies on the effects of physical activity on GI-tract disorders are warranted. Especially, the association between the exercise intensity and data addressing the underlying mechanism(s) of the exercise as the complementary therapy in the treatment of gastrointestinal disorders, require further determination in animal models and humans.

Abstract
Inflammatory bowel diseases are a heterogeneous group of disorders represented by two major phenotypic forms, Crohn’s disease and ulcerative colitis. Cross talk between adipokines and myokines, as well as changes in intestinal microcirculation, was proposed in pathogenesis of these disorders. C57BL/6 male mice were fed ad libitum for 12 weeks a standard (SD) or high-fat diet (HFD). After the adaptation period, two groups of animals fed SD or HFD were subjected to 6 weeks of the forced treadmill exercise and the experimental colitis was induced in both groups of sedentary and exercising mice fed SD and HFD by intra-colonic administration of 2,4,6-trinitrobenzenesulfonic acid. The disease activity index (DAI), colonic blood flow (CBF), the weight of animals, caloric intake, the mesenteric fad pad, the colonic oxidative stress markers malondialdehyde (MDA), reduced glutathione (GSH), and superoxide dismutase (SOD) activity and intestinal expression and protein content of proinflammatory markers were evaluated. Macroscopic and microscopic colitis in sedentary SD mice was accompanied by a significant fall in CBF and exacerbated in those fed a HFD. The contents of MDA, GSH, and SOD activity were significantly increased in both SD and HFD fed mice with treadmill exercise as compared with sedentary mice. In sedentary HFD mice a significant increase in the intestinal oxidative stress parameters and mucosal expression of IL-1β, TNF-α, IL-17, IFNγ, IL-6, and IL-10 protein were observed and these effects were aggravated in mice subjected to forced treadmill exercise. The mucosal expression of mRNA for TNF-α, IL-1β, iNOS, COX-2, SOD-1, SOD-2, GPx mRNAs, and the hypoxia inducible factor (HIF)-1α protein expression were upregulated in colonic mucosa of treadmill exercising HFD mice with colitis compared with those without exercise. We conclude that forced treadmill running exacerbates the severity of colonic damage in obese mice due to a fall in colonic microcirculation, an increase in oxidative stress, and the rise in expression and activity of proinflammatory biomarkers.

Abstract
BACKGROUND AND PURPOSE Besides hydrogen sulfide (H2S) and nitric oxide (NO), carbon monoxide (CO) contributes to the maintenance of gastric mucosal integrity. We investigated increased CO bioavailability effects on time-dependent dynamics of gastric ulcer healing mediated by particular growth factors, anti-inflammatory and molecular pathways. EXPERIMENTAL APPROACH Wistar rats with gastric ulcers induced by serosal acetic acid application (day 0) were treated i.g. throughout 3, 6 or 14 days with vehicle or CO-releasing tricarbonyldichlororuthenium (II) dimer (CORM-2, 2.5 mg/kg). Gross and microscopic alterations in gastric ulcer size and gastric blood flow (GBF) at ulcer margin were determined by planimetry, histology and laser flowmetry, respectively. Gastric mRNA/protein expressions of platelet derived growth factors (PDGFA-D), insulin-like growth factor (IGF-1), epidermal growth factor (EGF), hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGFA) and their receptors, heme oxygenases (HMOX), nuclear factor (erythroid-derived 2)-like 2 (Nrf-2), cyclooxygenase (COX-2), hypoxia inducible factor (HIF)-1α, anti-inflammatory annexin-1 and transforming growth factor (TGF-β1) were assessed by real-time PCR or Western blot. TGF-β1-3 and IL-10 plasma concentration were measured using Luminex platform. Prostaglandin E2 content at ulcer margin was assessed by ELISA. KEY RESULTS CORM-2 decreased ulcer area and increased GBF after 6 and 14 days of treatment comparing to vehicle. CO donor upregulated HGF, HGFr, VEGFR1, VEGFR2, TGF-β1, annexin-1 and maintained increased IGF-1, PDGFC and EGF expression at various time-intervals of ulcer healing. TGF-β3 and IL-10 plasma concentration were significantly increased after COMR-2 vs. vehicle. CONCLUSIONS CO time-dependently accelerates gastric ulcer healing and raises GBF at ulcer margin by mechanism involving subsequent upregulation of anti-inflammatory, growth promoting and angiogenic factors response, not observed physiologically.

Abstract
Melatonin is a tryptophan-derived molecule with pleiotropic activities which is produced in all living organisms. This "sleep" hormone is a free radical scavenger, which activates several anti-oxidative enzymes and mechanisms. Melatonin, a highly lipophilic hormone, can reach body target cells rapidly, acting as the circadian signal to alter numerous physiological functions in the body. This indoleamine can protect the organs against a variety of damaging agents via multiple signaling. This review focused on the role played by melatonin in the mechanism of esophagoprotection, starting with its short-term protection against acute reflux esophagitis and then investigating the long-term prevention of chronic inflammation that leads to gastroesophageal reflux disease (GERD) and Barrett's esophagus. Since both of these condition are also identified as major risk factors for esophageal carcinoma, we provide some experimental and clinical evidence that supplementation therapy with melatonin could be useful in esophageal injury by protecting various animal models and patients with GERD from erosions, Barrett's esophagus and neoplasia. The physiological aspects of the synthesis and release of this indoleamine in the gut, including its release into portal circulation and liver uptake is examined. The beneficial influence of melatonin in preventing esophageal injury from acid-pepsin and acid-pepsin-bile exposure in animals as well as the usefulness of melatonin and its precursor, L-tryptophan in prophylactic and supplementary therapy against esophageal disorders in humans, are also discussed.

Abstract
BACKGROUND Curcumin, a pleiotropic substance used for centuries in traditional medicine, exhibits antioxidant, anti-inflammatory and antiproliferative efficacy against various tumours, but the role of curcumin in gastroprotection is little studied. We determined the effect of curcumin against gastric haemorrhagic lesions induced by 75% ethanol and alterations in gastric blood flow (GBF) in rats with cyclooxygenase-1 (COX-1) and COX-2 activity inhibited by indomethacin, SC-560 or rofecoxib, inhibited NO-synthase activity, capsaicin denervation and blockade of TRPV1 receptors by capsazepine. METHODS One hour after ethanol administration, the gastric mucosal lesions were assessed by planimetry, the GBF was examined by H2 gas clearance, plasma gastrin was determined by radioimmunoassay, and the gastric mucosal mRNA expression of Cdx-2, HIF-1α, HO-1 and SOD 2 was analysed by RT-PCR. RESULTS Curcumin, in a dose-dependent manner, reduced ethanol-induced gastric lesions and significantly increased GBF and plasma gastrin levels. Curcumin-induced protection was completely reversed by indomethacin and SC-560, and significantly attenuated by rofecoxib, L-NNA, capsaicin denervation and capsazepine. Curcumin downregulated Cdx-2 and Hif-1α mRNA expression and upregulated HO-1 and SOD 2, and these effects were reversed by L-NNA and further restored by co-treatment of L-NNA with L-arginine. CONCLUSIONS Curcumin-induced protection against ethanol damage involves endogenous PG, NO, gastrin and CGRP released from sensory nerves due to activation of the vanilloid TRPV1 receptor. This protective effect can be attributed to the inhibition of HIF-1α and Cdx-2 expression and the activation of HO-1 and SOD 2 expression.

Abstract
BACKGROUND Aspirin exerts side effects within the gastrointestinal tract. Hydrogen sulfide (H2S) and carbon monoxide (CO) have been implicated in gastroprotection but the mechanism of beneficial action of these gaseous mediators against aspirin-induced damage has not been fully studied. We determined the involvement of afferent sensory neurons, calcitonin-gene-related peptide (CGRP), lipid peroxidation, and nitric oxide (NO) biosynthesis in gastroprotection of H2S-releasing NaHS and CO-releasing tricarbonyldichlororuthenium(II) dimer (CORM-2) against aspirin-induced injury. METHODS Wistar rats with or without capsaicin-induced denervation of sensory neurons were pretreated with vehicle, CORM-2 (5 mg/kg intragastrically), or NaHS (5 mg/kg intragastrically) with or without capsazepine (5 mg/kg intragastrically) or N G-nitro-L-arginine (L-NNA, 20 mg/kg intraperitoneally). The areas of aspirin-induced lesions and gastric blood flow (GBF) were assessed by planimetry and laser flowmetry respectively. Gastric mucosal messenger RNA and/or protein expression of CGRP, heme oxygenase 1, inducible nitric oxide synthase, cyclooxygenase 2, interleukin-1β, glutathione peroxidase 1 (GPx-1), and superoxide dismutase was determined by real-time PCR or Western blot. Malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE) content was determined by colorimetric assay. RESULTS Aspirin caused gastric lesions, decreased GBF, and raised MDA content, but pretreatment with NaHS and CORM-2 reduced these effects. Capsaicin-induced denervation or co-treatment with capsazepine reversed the gastroprotective and vasodilatory effects of NaHS but not those of CORM-2. L-NNA reversed NaHS-induced gastroprotection and partly reduced CORM-2-induced gastroprotection. NaHS and CORM-2 decreased MDA and 4-HNE content, restoring GPx-1 protein expression. CONCLUSIONS We conclude that H2S- but not CO-mediated gastroprotection against aspirin-induced injury involves afferent sensory nerves and partly NO activity. NaHS and CORM-2 prevented aspirin-induced gastric mucosal lipid peroxidation via restoration of microcirculation and antioxidative GPx-1 protein expression.

Abstract
Hydrogen sulfide (H2S) and carbon monoxide (CO) exert gastroprotection against acute gastric lesions. We determined the cross-talk between H2S and CO in gastric ulcer healing process and regulation of gastric blood flow (GBF) at ulcer margin. Male Wistar rats with acetic acid-induced gastric ulcers were treated i.g. throughout 9 days with vehicle (control), NaHS (0.1-10 mg/kg) +/- zinc protoporphyrin (ZnPP, 10 mg/kg), d,l-propargylglycine (PAG, 30 mg/kg), CO-releasing CORM-2 (2.5 mg/kg) +/- PAG. GBF was assessed by laser flowmetry, ulcer area was determined by planimetry/histology. Gastric mucosal H2S production was analysed spectrophotometrically. Protein and/or mRNA expression at ulcer margin for vascular endothelial growth factor (VEGF)A, epidermal growth factor receptor (EGFr), cystathionine-γ-lyase (CSE), cystathionine-β-synthase (CBS), 3-mercaptopyruvate sulfurtransferase (3-MST), heme oxygenases (HOs), nuclear factor (erythroid-derived 2)-like 2 (Nrf-2), cyclooxygenase (COX)-2, inducible nitric oxide synthase (iNOS), IL-1β, TNF-α and hypoxia inducible factor (HIF)-1α were determined by real-time PCR or western blot. IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, IL-13, IFN-γ, TNF-α, GM-CSF plasma concentration was assessed using Luminex platform. NaHS dose-dependently decreased ulcer area and increased GBF but ZnPP attenuated these effects. PAG decreased H2S production but failed to affect CORM-2-mediated ulcer healing and vasodilation. NaHS increased Nrf-2, EGFr, VEGFA and decreased pro-inflammatory markers expression and IL-1β, IL-2, IL-13, TNF-α, GM-CSF plasma concentration. CORM-2 decreased IL-1β and GM-CSF plasma levels. We conclude that NaHS accelerates gastric ulcer healing increasing microcirculation and Nrf-2, EGFr, VEGFA expression. H2S-mediated ulcer healing involves endogenous CO activity while CO does not require H2S. NaHS decreases systemic inflammation more effectively than CORM-2.

Abstract
Clinical use of non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin or naproxen is limited due to the gastrotoxicity evoked by these compounds. Endogenous hydrogen sulfide (H2s) and delivered via an H2s donor have been shown to play important role in the maintenance of gastric mucosal integrity. This study aimed to compare the effects of naproxen and an H2s-releasing naproxen derivative (ATB-346) on gastric lesion induction by water immersion and restraint stress (WRS), the alterations in gastric blood flow (GBF) and the influence of these drugs on systemic inflammation. Wistar rats were pretreated i.g. with vehicle, naproxen (20 mg/kg) or ATB-346 (equimolar dose) or NaHS (5 mg/kg), the H2s donor, combined with naproxen and exposed to 3.5 hours of WRS. The gastric lesion number and GBF were assessed by planimetry and laser Doppler flowmetry, respectively. Plasma concentrations of interleukins: IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α) and GM-CSF were determined by Luminex system and gastric mucosal protein expression of cystathionine-γ-lyase (CSE), cystathionine-β-synthase (CBS), 3-mercaptopyruvate sulfurtransferase (3-MST), nuclear factor (erythroid-derived 2)-like 2 (Nrf-2), hypoxia inducible factor-1α (HIF-1α), heme oxygenase-1 (HO-1) and cyclooxygenase (COX-2) were analyzed by Western blot. Pretreatment with naproxen increased the number of WRS stress-induced gastric lesions and significantly decreased GBF as compared with vehicle (p < 0.05). In contrast, pretreatment with ATB-346 or naproxen combined with NaHS significantly reduced WRS-lesions number and elevated GBF as compared with naproxen (p < 0.05). Naproxen significantly increased gastric mucosal protein expression of CSE, Nrf-2 and HIF-1α as compared with vehicle (p < 0.05), but failed to affect CBS, 3-MST and HO-1. ATB-346 significantly increased Nrf-2 and HO-1 protein expression as compared with vehicle (P < 0.05) but did not affect the protein expression of CSE, CBS, 3-MST or HIF-1α. ATB-346 but not naproxen decreased COX-2 protein expression in gastric mucosa compromised by WRS (p < 0.05). Exposure to WRS increased plasma concentration of all investigated cytokines (p < 0.05). ATB-346 but not naproxen decreased plasma content of IL-1α, IL-4, IL-5, IL-6, IL-10, IL-12, TNF-α and IFN-γ in rats exposed to WRS (p < 0.05). We conclude that H2s through its vasoactive properties attenuates the gastrotoxic effects of naproxen, which increased stress-induced hypoxia in gastric mucosa. In contrast to naproxen, ATB-346 decreased stress-induced systemic inflammation and pro-inflammatory COX-2 expression in the gastric mucosa. The decreased gastrotoxicity of ATB-346 could be due to upregulation of Nrf-2/HO-1 pathway mediated by the release of H2s.

Abstract
BACKGROUND AND PURPOSE Carbon monoxide (CO), a gaseous mediator produced by haem oxygenases (HOs), has been shown to prevent stress-, ethanol-, aspirin- and alendronate-induced gastric damage; however, its role in gastric ulcer healing has not been fully elucidated. We investigated whether CO released from tricarbonyldichlororuthenium (II) dimer (CORM-2) can affect gastric ulcer healing and determined the mechanisms involved in this healing action. EXPERIMENTAL APPROACH Gastric ulcers were induced in Wistar rats by serosal application of acetic acid. Animals received 9 days of treatment with RuCl3 [2.5 mg·kg-1 intragastrically (i.g.)], haemin (5 mg·kg-1 i.g.), CORM-2 (0.1-10 mg·kg-1 i.g.) administered alone or with zinc protoporphyrin IX (ZnPP, 10 mg·kg-1 i.g.), 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 5 mg·kg-1 i.g.), NG -nitro-l-arginine (l-NNA, 15 mg·kg-1 i.g.), indomethacin (5 mg·kg-1 i.g.) or glibenclamide (10 mg·kg-1 i.g.). Gastric ulcer area and gastric blood flow (GBF) were assessed planimetrically, microscopically and by laser flowmeter respectively. Gastric mRNA/protein expressions of EGF, EGF receptors, VEGFA, HOs, nuclear factor (erythroid-derived 2)-like 2 (Nrf2), COX-2, hypoxia-inducible factor (HIF)-1α and pro-inflammatory iNOS, IL-1β and TNF-α were determined by real-time PCR or Western blots. KEY RESULTS CORM-2 and haemin but not RuCl3 or ZnPP decreased ulcer size while increasing GBF. These effects were reduced by ODQ, indomethacin, l-NNA and glibenclamide. CORM-2 significantly decreased the expression of pro-inflammatory markers, Nrf2/HO1 and HIF-1α, and up-regulated EGF. CONCLUSIONS AND IMPLICATIONS CO released from CORM-2 or endogenously produced by the HO1/Nrf2 pathway accelerates gastric ulcer healing via an increase in GBF, an up-regulation in EGF expression and down-regulation of the inflammatory response.

Abstract
Hydrogen sulphide (H2S) is produced endogenously via two enzymes dependent on pyridoxal phosphate (PLP): cystathionine beta-synthase (CBS, EC 4.2.1.22), cystathionase γ-liase (CTH, EC 4.4.1.1), and a third, 3-mercaptopyruvate sulfurtransferase (MPST, EC 2.8.1.2). H2S strengthens the defence mechanisms of the gastric mucosal barrier, and plays an important role in gastroprotection, including the increased resistance to damage caused by various irritants and non-steroidal anti-inflammatory drugs. The study was conducted to determine the role of H2S in ulcerated gastric mucosa of rats caused by immobilization in cold water (WRS). The activity and expression of γ-cystathionase, cystathionine β-synthase, 3-mercaptopyruvate sulfurtransferase, and rhodanese was compared with healthy mucosa, together with H2S generation, and cysteine, glutathione, and cystathionine levels. The results showed that the defence mechanism against stress is associated with stimulation of the production of H2S in the tissue and confirmed the observed advantageous effect of H2S on healing of gastric ulcers. In case of animals pretreated with exogenous sources of H2S and NaHS, and some changes observed in the ulcerated gastric mucosa tend to return to values found in the healthy tissue, a finding that is in accordance with the previously determined gastroprotective properties of H2S. The results presented in this paper point to the possible role of rhodanese in H2S production in the gastric mucosa of rats, together with the earlier mentioned three enzymes, which are all active in this tissue.

Abstract
Hydrogen sulfide (H2S) is an endogenous mediator, synthesized from l-cysteine by cystathionine γ-lyase (CSE), cystathionine β-synthase (CBS) or 3-mercaptopyruvate sulfurtransferase (3-MST). The mechanism(s) involved in H2S-gastroprotection against ischemia/reperfusion (I/R) lesions and their time-dependent progression into deeper gastric ulcerations have been little studied. We determined the effect of l-cysteine, H2S-releasing NaHS or slow H2S releasing compound GYY4137 on gastric blood flow (GBF) and gastric lesions induced by 30 min of I followed by 3, 6, 24 and 48 h of R. Role of endogenous prostaglandins (PGs), afferent sensory nerves releasing calcitonin gene-related peptide (CGRP), the gastric expression of hypoxia inducible factor (HIF)-1α and anti-oxidative enzymes were examined. Rats with or without capsaicin deactivation of sensory nerves were pretreated i.g. with vehicle, NaHS (18–180 μmol/kg) GYY4137 (90 μmol/kg) or l-cysteine (0.8–80 μmol/kg) alone or in combination with (1) indomethacin (14 μmol/kg i.p.), SC-560 (14 μmol/kg), celecoxib (26 μmol/kg); (2) capsazepine (13 μmol/kg i.p.); and (3) CGRP (2.5 nmol/kg i.p.). The area of I/R-induced gastric lesions and GBF were measured by planimetry and H2-gas clearance, respectively. Expression of mRNA for CSE, CBS, 3-MST, HIF-1α, glutathione peroxidase (GPx)-1, superoxide dismutase (SOD)-2 and sulfide production in gastric mucosa compromised by I/R were determined by real-time PCR and methylene blue method, respectively. NaHS and l-cysteine dose-dependently attenuated I/R-induced lesions while increasing the GBF, similarly to GYY4137 (90 μmol/kg). Capsaicin denervation and capsazepine but not COX-1 and COX-2 inhibitors reduced NaHS- and l-cysteine-induced protection and hyperemia. NaHS increased mRNA expression for SOD-2 and GPx-1 but not that for HIF-1α. NaHS which increased gastric mucosal sulfide release, prevented further progression of acute I/R injury into deeper gastric ulcers at 6, 24 and 48 h of R. We conclude that H2S-induced gastroprotection against I/R-injury is due to increase in gastric microcirculation, anti-oxidative properties and afferent sensory nerves activity but independent on endogenous prostaglandins.

Abstract
Acetylsalicylic acid (ASA) is mainly recognized as painkiller or anti-inflammatory drug. However, ASA causes serious side effects towards gastrointestinal (GI) tract which limits its usefulness. Carbon monoxide (CO) and hydrogen sulfide (H2S) have been described to act as important endogenous messengers and mediators of gastroprotection but whether they can interact in gastroprotection against acute ASA-induced gastric damage remains unknown. In this study male Wistar rats were pretreated with 1) vehicle (saline, i.g.), 2) tricarbonyldichlororuthenium (II) dimer (CORM-2, 5mg/kg i.g.), 3) sodium hydrosulfide (NaHS, 5mg/kg i.g.), 4) zinc protoporphyrin (ZnPP, 10mg/kg i.p.), 5) D,L-propargylglycine (PAG, 30mg/kg i.g.), 6) ZnPP combined with NaHS, 7) PAG combined with CORM-2 or 8) 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 10mg/kg i.p.) combined with CORM-2 or NaHS and 30min later ASA was administered i.g. in a single dose of 125mg/kg. After 1h, gastric blood flow (GBF) was determined by H2 gas clearance technique and gastric lesions were assessed by planimetry and histology. CO content in gastric mucosa and COHb concentration in blood were determined by gas chromatography and H2S production was assessed in gastric mucosa using methylene blue method. Protein and/or mRNA expression for cystathionine-γ-lyase (CSE), cystathionine-β-synthase (CBS), 3-mercaptopyruvate sulfurtransferase (3-MST), heme oxygenase (HO)-1, HO-2, hypoxia inducible factor-alpha (HIF)-1α, nuclear factor (erythroid-derived 2)-like 2 (Nrf-2), cyclooxygenase (COX)-1 and COX-2, inducible nitric oxide synthase (iNOS) and interleukin (IL)-1β were determined by Western blot or real-time PCR, respectively. ASA caused hemorrhagic gastric mucosal damage and significantly decreased GBF, H2S production, CO content, mRNA or protein expression for CSE, 3-MST, HO-2 and increased mRNA and/or protein expression for CBS, HO-1, Nrf-2, HIF-1α, iNOS, IL-1β, COX-2 in gastric mucosa and COHb concentration in blood. Pretreatment with CORM-2 or NaHS but not with PAG decreased ASA-damage and increased GBF. ZnPP reversed protective and hyperemic effect of NaHS but PAG failed to affect CORM-2-induced gastroprotection. CORM-2 elevated CO content, mRNA or protein expression for HO-1, Nrf-2, and decreased expression of CBS, HIF-1α, COX-2, IL-1β, iNOS, the H2S production in gastric mucosa and COHb concentration in blood. NaHS raised mRNA or protein expression for CSE, COX-1 and decreased mRNA expression for IL-1β and COHb level in blood. We conclude that CO is involved in gastroprotection induced by H2S while beneficial protective action of CO released from CORM-2 in gastric mucosa seems to be H2S-independent. In contrast to H2S, CO ameliorates hypoxia, regulates Nrf-2 expression but similarly to H2S acts on sGC-dependent manner to restore gastric microcirculation and exhibit anti-inflammatory activity in gastric mucosa compromised by ASA.

Abstract
Carbon monoxide (CO) is a physiological gaseous mediator recently implicated in the mechanism of gastric mucosal defense due to its vasodilatory and antioxidative properties. Small quantities of endogenous CO are produced during heme degradation by heme oxygenase (HO-1), however, the involvement of the capsaicin-sensitive afferent neurons releasing calcitonin gene related peptide (CGRP) and anti-oxidative factors and mechanisms in the CO-induced gastroprotection against stress ulcerogenesis has been little studied. We investigated the possible role of CO released from the CO donor, tricarbonyldichlororuthenium (II) dimer (CORM-2) in the protection against water immersion and restraint stress (WRS)-induced lesions in rats with intact sensory nerves and those with capsaicin denervation and the accompanying changes in malondialdehyde (MDA) content considered as an index of lipid peroxidation, the activity of GSH and SOD-2 and gastric mucosal expression of antioxidative enzymes glutathione peroxidase (GPx) and SOD-2. Wistar rats with intact sensory nerves or those with capsaicin administered in total dose of 125 mg/kg s.c. within 3 days (capsaicin denervation) were pretreated either with 1) vehicle (saline) or 2) CORM-2 (0.1 - 0 mg/kg i.g.) with or without exogenous CGRP (10 μg/kg i.p.) and 30 min later exposed to 3.5 h of WRS. At the termination of WRS, the number of gastric lesions was counted and gastric blood flow (GBF) was assessed by H2-gas clearance technique. The mucosal content of MDA and reduced glutathione (GSH) and the activity of SOD-2 were determined and the expression of GPx-1 and SOD-2 mRNA in the gastric mucosa was analyzed by real-time PCR. The exposure of rats to 3.5 h of WRS resulted in numerous hemorrhagic gastric lesions and significantly decreased the GBF, raised MDA content and significantly decreased the mucosal SOD and GSH contents compared with intact gastric mucosa and these changes were exacerbated in rats with capsaicin denervation. Pretreatment with CORM-2 (1 mg/kg i.g.) which in our previous studies significantly reduced the ethanol and aspirin-induced gastric damage, significantly decreased the number of WRS-induced gastric lesions while raising the GBF and significantly increasing the activity of SOD and GSH (P < 0.05). The pretreatment with CORM-2 significantly decreased MDA content as compared with vehicle-pretreated rats exposed to WRS (P < 0.05). The reduction of WRS damage and the accompanying increase in the GBF as well as the significant decrease in MDA content and the increase in GSH content and SOD activity induced by CORM-2 (1 μg/kg i.g.) were all significantly altered in rats with capsaicin denervation (P < 0.05). The concurrent treatment of CORM-2 with exogenous CGRP in rats with or without sensory nerves tended to decrease the number of WRS lesions as compared with CORM-2 alone pretreated animals and significantly increased the GBF over the values measured in gastric mucosa of CORM-2 alone pretreated rats with or without capsaicin denervation. Such combined administration of CORM-2 and CGRP in rats with capsaicin denervation significantly inhibited an increase in MDA and 4-HNE content and evoked a significant increase in the GSH concentration (P < 0.05) remaining without significant effect on the increase in SOD activity observed with CORM-2 alone. The gastric mucosal expression of SOD-2- and GPx-1 mRNA was significantly increased as compared with those in intact gastric mucosa (P < 0.05). The pretreatment with CORM-2 applied with or without CGRP failed to significantly alter the mRNA expression for SOD-2 and GPx in the gastric mucosa of rats exposed to WRS. Both, the expression of SOD-2- and GPx-1 mRNA was significantly increased in capsaicin denervated rats exposed to WRS rats (P < 0.05) and this effect was abolished by the pretreatment with CORM-2. The expression of SOD-2 tended to decrease, though insignificantly, in rats pretreated with the combination of CORM-2 and CGRP as compared with that detected in CORM-2 alone in rats with capsaicin denervation. In contrast, the mRNA expression of GPx-1 was significantly decreased in gastric mucosa of capsaicin-denervated rats treated with the combination of CORM-2 and CGRP as compared with CORM-2 alone pretreated animals. We conclude that 1) CORM-2 releasing CO exerts gastroprotective activity against stress ulcerogenesis and this effect depends upon an increase in the gastric microcirculation and the vasodilatory activity of this gaseous mediator, and 2) the sensory nerve endings releasing CGRP can contribute, at least in part, to the CO-induced gastric hyperemia, the attenuation of gastric mucosal lipid peroxidation and prevention of oxidative stress as indicated by the CORM-2-induced normalization of the antioxidative enzyme expression enhanced in gastric mucosa of capsaicin-denervated rats.

Abstract
The inflammatory bowel disease (IBD) consisting of Crohn's disease (CD) and ulcerative colitis (UC) are defined as idiopathic, chronic and relapsing intestinal disorders occurring in genetically predisposed individuals exposed to environmental risk factors such as diet and microbiome changes. Since conventional drug therapy is expensive and not fully efficient, there is a need for alternative remedies that can improve the outcome in patients suffering from IBD. Whether exercise, which has been proposed as adjunct therapy in IBD, can be beneficial in patients with IBD remains an intriguing question. In this review, we provide an overview of the effects of exercise on human IBD and experimental colitis in animal models that mimic human disease, although the information on exercise in human IBD are sparse and poorly understood. Moderate exercise can exert a beneficial ameliorating effect on IBD and improve the healing of experimental animal colitis due to the activity of protective myokines such as irisin released from working skeletal muscles. CD patients with higher levels of exercise were significantly less likely to develop active disease at six months. Moreover, voluntary exercise has been shown to exert a positive effect on IBD patients' mood, weight maintenance and osteoporosis. On the other hand, depending on its intensity and duration, exercise can evoke transient mild systemic inflammation and enhances pro-inflammatory cytokine release, thereby exacerbating the gastrointestinal symptoms. We discuss recent advances in the mechanism of voluntary and strenuous exercise affecting the outcome of IBD in patients and experimental animal models.

Abstract
The antioxidizing properties of curcumin, a highly pleiotropic substance used for centuries in traditional medicine has been confirmed by numerous experimental and clinical studies. Curcumin exhibits anti-inflammatory, antiproliferative and anti-angiogenic actions inhibiting the development and progression of tumors but the efficacy of this compound to influence gastric acid secretion n in the stomach and to affect the gastric mucosal damage induced by non-topical ulcerogenes such as stress has been little studied. We determined the effect of curcumin on basal and pentagastrin- or histamine-stimulated gastric secretion, in rats with surgically implemented gastric fistulas and we assessed the contribution of gastric secretion, endogenous prostaglandin (PG), endogenous nitric oxide (NO), as well as sensory afferent nerves in the mechanisms underlying the potential gastroprotective effects of curcumin against stress-induced gastric mucosal lesions. Rats exposed to water immersion and restraint stress (WRS) for 3.5 h were pretreated either with: 1) vehicle (saline); 2) curcumin (2.5 - 100 mg/kg i.g.) or 3) curcumin (50 mg/kg i.g.) combined with or without indomethacin (5 mg/kg i.p.), SC-560 (5 mg/kg i.g.) or rofecoxib (10 mg/kg i.g.); 4) curcumin (50 mg/kg i.g.) co-administered with (L-NNA (20 mg/kg i.p.) with or without L-arginine (200 mg/kg i.g.), a substrate for NO-synthase; 5) curcumin (50 mg/kg i.g.) administered in rats with intact or capsaicin-induced functional ablation of sensory nerve fibers, and 6) curcumin (50 mg/kg i.g.) administered with capsazepine (5 mg/kg i.g.), the antagonist of vanilloid TRPV1 receptor. The number of gastric lesions was determined by planimetry, the gastric blood flow (GBF) was assessed by H2-gas clearance technique, the plasma gastrin concentrations were measured using the radioimmunoassay (RIA) and the expression of mRNA for tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in gastric mucosa was evaluated by reverse transcription polymerase chain reaction (RT-PCR). Curcumin dose-dependently reduced the WRS-induced gastric lesions, the dose inhibiting these lesions by 50% being about 50 mg/kg. These effects of curcumin were accompanied by an increase in GBF and the reduction in basal and histamine- or pentagastrin-stimulated gastric acid secretion. The protective and hyperemic activities of curcumin (50 mg/kg i.g.) against WRS lesions were significantly attenuated (P < 0.05) in rats pretreated with rofecoxib and SC-560 and completely reversed (P < 0.01) by indomethacin. L-NNA significantly reduced (P < 0.05) the decrease in WRS-induced lesions and the accompanying rise in GBF caused by curcumin and these effects were restored by concurrent treatment with L-arginine (200 mg/kg i.g.). The curcumin-induced decrease in the number of WRS-induced gastric lesions and accompanying increase in the GBF were significantly attenuated (P < 0.05) in capsaicin-denervated rats and in those pretreated with capsazepine. These effects of curcumin in rats with capsaicin denervation were restored by concomitant treatment with exogenous calcitonin gene related pepetide (CGRP) combined with curcumin and subsequently exposed to WRS. The expression of mRNA for TNF-α, COX-2 and iNOS was significantly increased (P < 0.05) in vehicle-pretreated control rats exposed to WRS and significantly attenuated (P < 0.05) by curcumin administered in graded dosages. We conclude that curcumin exerts gastroprotective and hyperemic activities against experimental stress-induced gastric lesions by mechanism involving endogenous prostaglandins, NO, the neuropeptides such as CGRP released from capsaicin-sensitive afferent nerves and the activation of vanilloid TRPV1 receptors located on these sensory nerve terminals.

Abstract
Nitric oxide (NO) and hydrogen sulfide (H2S) are known as biological messengers; they play an important role in human organism and contribute to many physiological and pathophysiological processes. NO is produced from l-arginine by constitutive NO synthase (NOS) and inducible NOS enzymatic pathways. This gaseous mediator inhibits platelet aggregation, leukocyte adhesion and contributes to the vessel homeostasis. NO is known as a vasodilatory molecule involved in control of the gastric blood flow (GBF) and the maintenance of gastric mucosal barrier integrity in either healthy gastric mucosa or that damaged by strong irritants. Biosynthesis of H2S in mammals depends upon two enzymes cystathionine-β-synthase and cystathionine γ-lyase. This gaseous mediator, similarly to NO and carbon monoxide, is involved in neuromodulation, vascular contractility and anti-inflammatory activities. For decades, H2S has been known to inhibit cytochrome c oxidase and reduce cell energy production. Nowadays it is generally considered to act through vascular smooth muscle ATP-dependent K+ channels, interacting with intracellular transcription factors and promote sulfhydration of protein cysteine moieties within the cell, but the mechanism of potential gastroprotective and ulcer healing properties of H2S has not been fully explained. The aim of this review is to compare current results of the studies concerning the role of H2S and NO in gastric mucosa protection and outline areas that may pose new opportunities for further development of novel therapeutic targets.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs), especially acetylsalicylic acid (ASA), are commonly used in the therapy of various diseases. However, the serious side effects of these drugs, such as bleedings, acute lesions, gastric ulcers, and even intestinal perforations, are widely recognized. NSAIDs inhibit cyclooxygenase (COX) activity resulting in the suppression of mucosal generation of gastroprotective prostaglandins (PGs) derived from a constitutive isoform, COX-1, as well as an inducible isoform, COX-2. COX-1-derived PGs are responsible for gastroprotection, while PGs generated via COX-2 activity also play an important role in gastroprotection and ulcer healing. Recently, a new class of NSAIDs has been developed by adding NO moiety to conventional NSAIDs. In contrast to native NSAIDs, their NO-releasing derivatives such as NO-ASA were found to exhibit lower gastric toxicity despite inhibiting both COX-1 and COX-2 activity in the gastric mucosa. Similar limited gastrointestinal toxicity and protective actions were observed with a new class of hydrogen sulfide (H₂S)-releasing NSAIDs, such as H₂S-releasing naproxen (ATB-346). Dual antiplatelet therapy with ASA and clopidogrel increases the risk of gastrointestinal bleeding in patients with acute coronary syndrome in whom concomitant treatment with a proton-pump inhibitor (PPI) was less effective owing to the interaction of clopidogrel and PPI with the same hepatic cytochrome P-450. In conclusion, new derivatives of NSAIDs releasing vasoactive gaseous mediators NO or H₂S are associated with fewer gastrointestinal adverse effects, suggesting that, in the future, they may be used as a safer alternative in everyday clinical practice and antithrombotic therapy.
