Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease that causes chronic inflammation in the large intestine. The etiology of UC is complex and incompletely understood, with potential contributing factors including genetic susceptibility, environmental influences, immune dysregulation, and gut barrier dysfunction. Despite available therapeutic drugs, the suboptimal cure rate for UC emphasizes the necessity of developing novel therapeutics. Traditional Chinese Medicine (TCM) has attracted great interest in the treatment of such chronic inflammatory diseases due to its advantages, such as multi-targets and low side effects. In this study, a mouse model of Dextran Sulfate Sodium (DSS)-induced acute colitis was established and the efficacy of Zhenqi Granule, a TCM preparation composed of the extractives from Astragali Radix and Fructus Ligustri Lucidi, was evaluated. The results showed that treatment with Zhenqi Granule prior to or post-DSS induction could alleviate the symptoms of colitis, including weight loss, diarrhea, hematochezia, colon length shortening, and pathological damage of colon tissues of the DSS-treated mice. Further, network pharmacology analysis showed that there were 98 common targets between the active components of Zhenqi Granule and the targets of UC, and the common targets were involved in the regulation of inflammatory signaling pathways. Our results showed that Zhenqi Granule had preventive and therapeutic effects on acute colitis in mice, and the mechanism may be that the active components of Zhenqi Granule participated in the regulation of inflammatory response. This study provided data reference for further exploring the mechanism of Zhenqi Granule and also provided potential treatment strategies for UC.

[PMID: 37213508 PMCID: PMC10196369 DOI: 10.3389/fmicb.2023.1182006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 04/17/2023] [Indexed: 05/23/2023] Open
Abstract
Background Colorectal cancer (CRC) is a highly prevalent cancer, and the global healthcare system bears a significant burden due to its incidence. Modulating the gut microbiota is a promising approach to enhance the efficacy of CRC treatment and reduce its adverse effects. The causal relationship between specific microorganisms' presence and CRC development has been widely validated. However, few studies have investigated this relationship using bibliometric methods. Therefore, this study analyzed the research hotspots and trends in human gut microbiology and CRC over the last two decades from a bibliometric perspective. The study aims to provide novel insights into basic and clinical research in this field. Methods The articles and reviews on gut microbiota in CRC were obtained from the Web of Science Core Collection (WOSCC) on November 2, 2022. CiteSpace and VOSviewer were used to conduct the bibliometric and knowledge-map analysis. Results A total of 2,707 publications were obtained, with a rapid increase in the number of publications since 2015. The United States and China are the main contributors in this field and have established a network of partnerships in several countries. 414 academic journals have published articles on this topic. The author with the highest number of publications is Jun Yu from the Chinese University of Hong Kong. In addition to "intestinal flora" and "colorectal cancer," high frequency terms in the keyword co-occurrence network analysis included inflammatory bowel disease, Fusobacterium nucleatum, inflammation, long-chain fatty acids, ulcerative colitis, bile acids, and resistant starch. Analysis of keyword trends using burst testing revealed that biomarkers, abnormal crypt foci, bifidobacteria, β-glucuronidase, short-chain fatty acids, bile acids, and DNA methylation are at the forefront of research in this area. Conclusion The findings of this study provide a bibliometric analysis and visualization of the key research areas in gut microbiota and CRC over the past 20 years. The results suggest that the role of gut microbiota in CRC and its underlying mechanisms should be closely monitored, particularly in the areas of biomarkers, metabolic pathways, and DNA methylation, which may emerge as hot topics in this field.

A Polyclonal Aptamer Library for the Specific Binding of the Gut Bacterium Roseburia intestinalis in Mixtures with Other Gut Microbiome Bacteria and Human Stool Samples. Int J Mol Sci 2022; 23:ijms23147744. [PMID: 35887092 PMCID: PMC9317077 DOI: 10.3390/ijms23147744] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 07/11/2022] [Accepted: 07/11/2022] [Indexed: 02/07/2023] Open
Abstract
Roseburia intestinalis has received attention as a potential probiotic bacterium. Recent studies have demonstrated that changes in its intestinal abundance can cause various diseases, such as obesity, enteritis and atherosclerosis. Probiotic administration or fecal transplantation alter the structure of the intestinal flora, offering possibilities for the prevention and treatment of these diseases. However, current monitoring methods, such as 16S rRNA sequencing, are complex and costly and require specialized personnel to perform the tests, making it difficult to continuously monitor patients during treatment. Hence, the rapid and cost-effective quantification of intestinal bacteria has become an urgent problem to be solved. Aptamers are of emerging interest because their stability, low immunogenicity and ease of modification are attractive properties for a variety of applications. We report a FluCell-SELEX polyclonal aptamer library specific for R. intestinalis isolated after seven evolution rounds, that can bind and label this organism for fluorescence microscopy and binding assays. Moreover, R. intestinalis can be distinguished from other major intestinal bacteria in complex defined mixtures and in human stool samples. We believe that this preliminary evidence opens new avenues towards aptamer-based electronic biosensors as new powerful and inexpensive diagnostic tools for the relative quantitative monitoring of R. intestinalis in gut microbiomes.

Abstract
Age-related diseases are associated with increased morbidity in the past few decades and the cost associated with the treatment of these age-related diseases exerts a substantial impact on social and health care expenditure. Anti-aging strategies aim to mitigate, delay and reverse aging-associated diseases, thereby improving quality of life and reducing the burden of age-related pathologies. The natural dietary antioxidant supplementation offers substantial pharmacological and therapeutic effects against various disease conditions. Astaxanthin is one such natural carotenoid with superior antioxidant activity than other carotenoids, as well as well as vitamins C and E, and additionally, it is known to exhibit a plethora of pharmacological effects. The present review summarizes the protective molecular mechanisms of actions of astaxanthin on age-related diseases of multiple organs such as Neurodegenerative diseases [Alzheimer's disease (AD), Parkinson's disease (PD), Stroke, Multiple Sclerosis (MS), Amyotrophic lateral sclerosis (ALS), and Status Epilepticus (SE)], Bone Related Diseases [Osteoarthritis (OA) and Osteoporosis], Cancers [Colon cancer, Prostate cancer, Breast cancer, and Lung Cancer], Cardiovascular disorders [Hypertension, Atherosclerosis and Myocardial infarction (MI)], Diabetes associated complications [Diabetic nephropathy (DN), Diabetic neuropathy, and Diabetic retinopathy (DR)], Eye disorders [Age related macular degeneration (AMD), Dry eye disease (DED), Cataract and Uveitis], Gastric Disorders [Gastritis, Colitis, and Functional dyspepsia], Kidney Disorders [Nephrolithiasis, Renal fibrosis, Renal Ischemia reperfusion (RIR), Acute kidney injury (AKI), and hyperuricemia], Liver Diseases [Nonalcoholic fatty liver disease (NAFLD), Alcoholic Liver Disease (AFLD), Liver fibrosis, and Hepatic Ischemia-Reperfusion (IR) Injury], Pulmonary Disorders [Pulmonary Fibrosis, Acute Lung injury (ALI), and Chronic obstructive pulmonary disease (COPD)], Muscle disorders (skeletal muscle atrophy), Skin diseases [Atopic dermatitis (ATD), Skin Photoaging, and Wound healing]. We have also briefly discussed astaxanthin's protective effects on reproductive health.

Prostaglandin E-major urinary metabolite diagnoses mucosal healing in patients with ulcerative colitis in remission phase. J Gastroenterol Hepatol 2022; 37:847-854.

Abstract
BACKGROUND AND AIM Ulcerative colitis (UC) is usually detected by clinical symptoms, such as bleeding and diarrhea; however, it is rather difficult to assess during asymptomatic clinical remission (CR). Hence, there is a need for a biomarker that can reliably detect UC during remission. We previously reported on the utility of the prostaglandin E-major urinary metabolite (PGE-MUM) as a biomarker reflecting UC activity. In this study, we evaluated the effectiveness of the PGE-MUM in the diagnosis of endoscopic, histological, and histo-endoscopic mucosal remission of UC, comparing with fecal tests. METHODS This prospective study was conducted at the Jikei University Hospital between August 2017 and January 2021. Patients with UC in CR scheduled to undergo colonoscopy were included. The association between the PGE-MUM with endoscopic remission (ER), histological remission (HR), and complete mucosal healing (CMH, defined as histo-endoscopic remission) was analyzed. We also compared the area under the curve (AUC) for the receiver operating characteristic curves between PGE-MUM, fecal calprotectin (FC), and fecal immunochemical test (FIT). RESULTS In total, 128 patients were analyzed. PGE-MUM differed significantly in ER versus non-ER (14.5 vs 16.7, P = 0.028), HR versus non-HR (14.2 vs 17.4, P = 0.004), and CMH versus non-CMH (14.3 vs 16.7, P = 0.021). There were no significant differences between the AUCs for PGE-MUM, FC, and FIT for ER, HR, or CMH. CONCLUSIONS The PGE-MUM can determine CMH in UC even during CR, regardless of the disease phenotype, indicating its clinical benefit for non-invasive monitoring.

Abstract
Background Ulcerative colitis (UC) has become one of the fastest-growing severe diseases worldwide with high morbidity. This research aimed to explore the function of lncRNA UCA1 in UC progression. Methods RT-qPCR analysis was used to examine the expression of UCA1 level in colonic mucosa tissues of UC patients. Then, fetal human cells (FHCs) were stimulated by LPS to induce inflammatory injury. CCK-8, flow cytometry and ELISA were adopted to determine the influence of UCA1 depletion on cell viability, apoptosis and pro-inflammatory factors levels in LPS-induced FHCs. The interaction between UCA1 and miR-331-3p or BRD4 was confirmed by luciferase reporter assay. The expressions of key factors involved in NF-κB pathway were assessed by Western blotting. Results LncRNA UCA1 level was elevated in colonic mucosa tissues of UC patients. LPS stimulation restrained cell viability and promoted the apoptosis and inflammatory factors levels, thus inducing FHCs inflammatory injury, while these effects were partially abolished by UCA1 knockdown. Moreover, it was found that UCA1 silence improved LPS-triggered cell injury via miR-331-3p. In addition, BRD4 was directly targeted by miR-331-3p, and BRD4 deficiency neutralized the effects of miR-331-3p repression on LPS-triggered injury in LPS-treated FHCs. Conclusion Our data determined that UCA1 knockdown attenuated UC development via targeting the miR-331-3p/BRD4/NF-κB pathway.

Abstract
Ulcerative colitis (UC) is a chronic and relapsing inflammatory bowel disorder in the colon and rectum leading to low life-quality and high societal costs. Ursolic acid (UA) is a natural product with pharmacological and biological activities. The studies are aimed at investigating the protective and treatment effects of UA against the dextran sulfate sodium- (DSS-) induced UC mouse model and its underlying mechanism. UA was orally administered at different time points before and after the DSS-induced model. Mice body weight, colon length, and histological analysis were used to evaluate colon tissue damage and therapeutic evaluation. Intestinal transcriptome and microbe 16 s sequencing was used to analyze the mechanisms of UA in the prevention and treatment of UC. The early prevention effect of UA could effectively delay mouse weight loss and colon length shorten. UA alleviated UC inflammation and lowered serum and colon IL-6 levels. Three classical inflammatory pathways: MAPKs, IL-6/STAT3, and PI3K were downregulated by UA treatment. The proportion of macrophages and neutrophils in inflammatory cell infiltration was reduced in UA treatment groups. UA could significantly reduce the richness of intestinal flora to avoid the inflammatory response due to the destruction of the intestinal epithelial barrier. The function of UA against UC was through reducing intestinal flora abundance and regulating inflammatory and fatty acid metabolism signaling pathways to affect immune cell infiltration and cytokine expression.

Abstract
The mouse intestinal parasite Heligmosomoides polygyrus demonstrates adaptation to the inflammatory milieu as a result of colitis induced by dextran sulphate sodium (DSS). Nematodes from mice with colitis had different effects on dendritic cells than nematodes from mice without colitis. Immature JAWSII cells pre-exposed to L4 stage H. polygyrus from DSS-treated mice were adoptively transferred to mice with induced colitis. After two days, a higher disease activity index, macroscopic damage score and colon histology score were observed. MLN T cells isolated nine days after transfer demonstrated proinflammatory IFN-γ and IL-17 production. Transfer of JAWSII stimulated with male or female L4 larvae from a control invasion resulted in a slight improvement of colitis; in addition, dendritic cells exposed to H. polygyrus female L4 larvae, provoked migration of CD8+CD25+ T cells from MLN to the colon. Nematodes from an inflammatory environment changed cytokine production by dendritic cells. Inflammatory milieu changing nematode immunomodulatory activity affects dendritic cell functions, which offers new insight into the helminth-host relationship.

Abstract
Sarcocystis spp. are intracellular protozoan parasites with an intermediate-definitive host life cycle based on a prey-predator relationship. Sarcocystis infection is common among different vertebrates including humans. The pathogenicity of Sarcocystis spp. is of varied significance including a possible lethal effect for the host. The goal of the present study was to investigate the inflammatory activity of Sarcocystis spp. in different organs of naturally infected camels. The tongue, esophagus, heart, diaphragm, and skeletal muscles were collected from 50 camels, and the tissues assessed for the presence of Sarcocystis spp. by macroscopic examination, light microscopy, and transmission electron microscopy (TEM). Moreover, expression of the interleukin (IL)-6 was analyzed using reverse transcriptase quantitative polymerase chain reaction (qPCR). Microscopic Sarcocystis spp. cysts were found in camels. TEM identified the cysts as Sarcocystis camelicanis (S. camelicanis). Sarcocystis infection increased inflammation by stimulation of IL-6 expression in different organs of the camels, particularly in those from the Al-Qassim region.

[PMID: 33015841 DOI: 10.1111/jfbc.13488] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 08/27/2020] [Accepted: 09/04/2020] [Indexed: 12/18/2022]
Abstract
Jangkanghwan (JKH) can delay weight loss in mice, promote weight gain during recovery, and reduce colonic shortening and colon weight. In addition, the murine disease activity index was controlled after treatment using JKH. It can reduce the content of pro-inflammatory factors in serum and expression in tissues, such as interleukin (IL)-6, IL-1β, tumor necrosis factor-α, interferon-γ, cyclooxygenase-2, and nuclear factor kappa-B; in contrast, the content and expression of IL-10 and the inhibitor of nuclear factor kappa-B kinase-α in the serum and tissues were increased. The mRNA expression of the colitis characteristic biomarker monocyte chemoattractant protein-1 and macrophage inflammatory protein-3α were reduced in colon tissues. Using next-generation sequencing technology, the Bacteroidetes phylum in the JKH group decreased, while the Firmicutes phylum increased, and the number of beneficial bacteria-Bifidobacteriaceae, Lactobacillaceae, and Akkermansiaceae-increased. PRACTICAL APPLICATIONS: JKH is a mixture of colonic healthy foods composed of Atractylodes macrocephala koidzumi, radish leaves, Viscum album var. coloratum, dried Zingiber officinale Roscoe, etc. According to UPLC-Q-TOF MS analysis, JKH consists mainly of 17 active substances, such as pheophorbide A, nabumetone alcohol, dehydrocostus lactone, plantamajoside, kaempferol 3, 7-dirhamnoside, quercetin 3-D-glucuronide, and viscumneoside III. We investigated the preventive effects of JKH on dextran sulfate sodium (DSS)-induced ulcerative colitis in a murine model and found that JKH can reduce the damage in mice caused by DSS treatment.

Abstract
The aim of the present paper is to review the effects of non-digestible oligosaccharides (NDO) on immunity, focusing on their microbiota-independent mechanisms of action, as well as to explore their potential beneficial role in inflammatory bowel diseases (IBD). IBD are chronic, inflammatory conditions of the gastrointestinal tract. Individuals with IBD have an aberrant immune response to commensal microbiota, resulting in extensive mucosal inflammation and increased intestinal permeability. NDO are prebiotic fibres well known for their role in supporting intestinal health through modulation of the gut microbiota. NDO reach the colon intact and are fermented by commensal bacteria, resulting in the production of SCFA with immunomodulatory properties. In disease states characterised by increased gut permeability, prebiotics may also bypass the gut barrier and directly interact with intestinal and systemic immune cells, as demonstrated in patients with IBD and in infants with an immature gut. In vitro models show that fructooligosaccharides, inulin and galactooligosaccharides exert microbiota-independent effects on immunity by binding to toll-like receptors on monocytes, macrophages and intestinal epithelial cells and by modulating cytokine production and immune cell maturation. Moreover, animal models and human supplementation studies demonstrate that some prebiotics, including inulin and lactulose, might reduce intestinal inflammation and IBD symptoms. Although there are convincing preliminary data to support NDO as immunomodulators in the management of IBD, their mechanisms of action are still unclear and larger standardised studies need to be performed using a wider range of prebiotics.

Anti-inflammation of Erianin in dextran sulphate sodium-induced ulcerative colitis mice model via collaborative regulation of TLR4 and STAT3. Chem Biol Interact 2020; 324:109089. [PMID: 32272095 DOI: 10.1016/j.cbi.2020.109089] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 03/14/2020] [Accepted: 04/02/2020] [Indexed: 12/12/2022]
Abstract
Ulcerative colitis (UC) is a chronic, idiopathic and inflammatory disease of the rectal and colonic mucosa. Studies have shown that Toll-like receptors (TLR) 4 and Signal Transducer and Activator of Transcription 3 (STAT3)-mediated the decline in immune function and inflammatory infiltration are potential pathomechanism of UC occurrence and development. In this study, the anti-inflammation of Erianin, a natural bibenzyl compound with the antioxidant, antitumor, and anti-inflammatory activities, was investigated in a dextran sodium sulphate-induced UC mouse model. Three-week Erianin administration resulted in the increment on the body weight and colon length, and the reduction on the activity index score of UC mice. Liver, spleen, and renal organ indexes and pathological observations confirmed that Erianin was not cytotoxic and had an effect of improving immune organ function. The haematoxylin and eosin staining sections of colon tissue show Erianin's effect of reversing inflammation in the mucosal laye. Proteomic analysis and enzyme-linked immunosorbent assay indicated that Erianin regulated the levels of inflammatory and oxidative stress-related factors and immunochemokines in serum and colon tissues thereby reducing cell peroxidative damage and reducing immune inflammatory responses. Further data obtained by Western Blotting confirmed that Erianin's anti-UC activity was mediated by inhibiting the TLR4 and STAT3 signaling.

Abstract
Background Ulcerative colitis (UC) is a modern refractory disease, and its etiology has been difficult to discern. Studies have shown that UC is closely associated with the gut microbiota. Garidisan is composed of wild poppy and Artemisia frigida Willd and is commonly used for the treatment of UC in Inner Mongolia, China. In clinical settings, Garidisan has been found to treat UC effectively, with low recurrence. Previous studies have shown that Garidisan has a good therapeutic effect on mice with UC, but the therapeutic mechanism is still unclear. In this study, we investigated the regulatory effect of Garidisan on dysbiosis of the gut microbiota in a UC mouse model and explored the possible mechanism of the therapeutic effect of Garidisan on UC. Methods The UC mouse model was established by the dextran sulfate sodium (DSS) circulating free water drinking method, and the luminal contents were sampled under sterile conditions. High-throughput sequencing of the 16S rRNA gene V3 + V4 region of the luminal contents of the control group, model group, and Garidisan group was conducted, and clustering of operational taxonomic units (OTUs) and species annotation were performed. The differences in species composition and microbial community structure between individual groups of samples were analyzed using MetaStat, LefSe, rank sum test, and Bayesian causal network analysis. Results The UC mouse model was successfully established and the sequencing results were of adequate quality. There were significant differences in the diversity of luminal contents between the control group, model group, and Garidisan group, and the differences between groups were greater than those within any group. The therapeutic effect of Garidisan on UC is attributed to the direct effect on the Lachnospiraceae family of bacteria. Conclusion Garidisan has a good regulatory effect on the gut microbiota, and Lachnospiraceae could be an important direct target of Garidisan for the treatment of UC.

Abstract
BACKGROUND Recent studies have found gut microbiota to be closely associated with onset and perpetuation of UC. Currently, studies about gut microbiota have mainly covered samples collected from the intestinal lumen. However, the luminal flora is only part of the gut microbiota. Studies of the changes in mucosal flora under pathological conditions have been lacking. In this study, we investigated the correlation between the onset of UC and flora changes in different intestinal layers. METHODS The dextran sulfate sodium(DSS)-induced UC model was established by exposing mice to cycles of DSS. The luminal contents, an inner mucus layer, and outer mucus layer were harvested under sterile conditions. The samples were then analyzed using high-throughput sequencing of 16S rRNA V3 + V4 amplicons. The colonic microbiota composition and diversity were analyzed and compared using MetaStat, LefSe, multivariate analysis of variance, and spatial statistics. RESULTS The DSS-induced UC mouse model was successfully established. The diversity of the microbiota from luminal content, the outer mucus layer, and inner mucus layer were significantly different in both control and UC model groups. The statistically different OTUs belonged to Lachnospiraceae and Ruminococcaceae families within the order Clostridiales were mainly localized to the outer mucus layer. CONCLUSIONS The alterations in flora composition and diversity mainly occurred in the colonic outer mucus layer. The change of flora in the colonic mucus layers is of great significance in the understanding of common features of gut flora in IBD and the understanding of the relationship between gut flora and disease progression.

Treatment of Dextran Sulfate Sodium-Induced Colitis with Mucosa-Associated Lymphoid Tissue Lymphoma Translocation 1 Inhibitor MI-2 Is Associated with Restoration of Gut Immune Function and the Microbiota. Infect Immun 2018; 86:IAI.00091-18.

Abstract
Disruption of the healthy intestinal microbiome and homeostasis of the intestinal immune system, which are closely interactive, are two key factors for ulcerative colitis. Here, we show that MI-2, a selective inhibitor of mucosa-associated lymphoid tissue lymphoma translocation-1 (MALT1), alleviated excessive inflammatory responses and was associated with restoration of healthy intestinal microbiome in mice suffering from dextran sulfate sodium (DSS)-induced colitis. We found that the diversity of intestinal microbiome of mice with DSS-induced colitis was significantly lower than that of healthy mice. However, MI-2 treatment in mice with DSS-induced colitis resulted in restored microbially diverse populations. To understand the possibility of the beneficial effect of the restored microbially diverse populations of MI-2-treated mice with DSS-induced colitis, we showed that inserting fecal microbiota from MI-2-treated mice with DSS-induced colitis and healthy control mice into mice with DSS-induced colitis could alleviate symptoms of colitis. The possibility of MI-2 treatment in DSS-induced colitis, associated with restoration of healthy microbially diverse populations in addition to reshaping host immune modulating capacity by reducing inflammatory cytokines (tumor necrosis factor alpha, interleukin-1β [IL-1β], IL-17α, and IL-22), may be considered therapeutic for ulcerative colitis.

Abstract
Objective Dietary antigens are common luminal antigens in the gastrointestinal tract and have been considered to contribute to the pathogenesis of inflammatory bowel disease (IBD). We analyzed the levels of food-specific IgGs against a variety of dietary antigens, explored the clinical relevance of food allergy to the pathogenesis of IBD, and investigated whether or not infliximab (IFX) treatment could regulate the immune responses induced by dietary antigens. Methods A total of 301 IBD patients, including 201 patients with Crohn's disease (CD) and 100 patients with ulcerative colitis (UC), were recruited, and their serum food-specific IgGs against 14 food antigens were detected by a semi-quantitative enzyme linked immunosorbent assay (ELISA). Total serum IgG and IgE levels were measured by immunonephelometry and fluorescent enzyme immunoassay, respectively. Simultaneously, the relevant medical records and clinical data were collected for further analyses. Results Food-specific IgGs against egg, milk, wheat, corn, rice, tomato, codfish, and soybean antigens were found to be significantly increased in the sera of CD patients compared with UC patients and healthy controls (p<0.01). The levels of total serum IgG and IgE were also significantly higher in CD patients than in healthy controls (p<0.01). The titers of corn- and tomato-specific IgGs were found to be significantly correlated with total serum IgG in CD patients (p<0.05), while the titers of egg-, milk-, and wheat-specific IgGs were correlated with total serum IgE (p<0.05). Interestingly, IFX therapy was able to down-regulate the food-specific IgG-mediated immune response markedly in active CD patients. Conclusion Food-specific IgGs against egg, milk, wheat, corn, rice, tomato, codfish, and soybean are highly increased in the sera of CD patients. IFX treatment was able to down-regulate the levels of food-specific IgGs by suppressing intestinal inflammation and promoting mucosal healing. Therefore, food-specific IgGs may serve as an important approach in the diagnosis and management of food allergy in IBD.

Abstract
G Protein Coupled Receptor 109A (GPR109A), which belongs to the G protein coupled receptor family, can be activated by niacin, butyrate, and β-hydroxybutyric acid. Here, we assessed the anti-inflammatory activity of sodium butyrate (SB) on 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis mice, an experimental model that resembles Crohn's disease, and explored the potential mechanism of SB in inflammatory bowel disease (IBD). In vivo, experimental GPR109a-/- and wild-type (WT) mice were administered SB (5g/L) in their drinking water for 6weeks. The mice were then administered TNBS via rectal perfusion to imitate colitis. In vitro, RAW246.7 macrophages, Caco-2 cells, and primary peritoneal macrophages were used to investigate the protective roles of SB on lipopolysaccharide (LPS)-induced inflammatory response and epithelium barrier dysfunction. In vivo, SB significantly ameliorated the inflammatory response and intestinal epithelium barrier dysfunction in TNBS-induced WT mice, but failed to provide a protective effect in TNBS-induced GPR109a-/- mice. In vitro, pre-treatment with SB dramatically inhibited the expression of TNF-α and IL-6 in LPS-induced RAW246.7 macrophages. SB inhibited the LPS-induced phosphorylation of the NF-κB p65 and AKT signaling pathways, but failed to inhibit the phosphorylation of the MAPK signaling pathway. Our data indicated that SB ameliorated the TNBS-induced inflammatory response and intestinal epithelium barrier dysfunction through activating GPR109A and inhibiting the AKT and NF-κB p65 signaling pathways. These findings therefore extend the understanding of GPR109A receptor function and provide a new theoretical basis for treatment of IBD.

Abstract
Mucosa-associated-lymphoid-tissue lymphoma-translocation gene 1 (MALT1), a paracaspase and essential regulator for nuclear factor kB (NF-κB) activation, plays an important role in innate and adaptive immunity. Suppression of MALT1 protease activity with small molecule inhibitors showed promising efficacies in subtypes of B cell lymphoma and improvement in experimental autoimmune encephalomyelitis model. However, whether MALT1 inhibitors could ameliorate colitis remains unclear. In the present study, we examined the pharmacological effect of two specific MALT1 inhibitors MI-2 and mepazine on the dextran sulfate sodium (DSS)-induced experimental colitis in mice, followed by mechanistic analysis on NF-κB and NLRP3 inflammasome activation. Treatment with MI-2 and mepazine dose-dependently attenuated symptoms of colitis in mice, evidenced by reduction in the elevated disease activity index, the shortening of colon length as well as the histopathologic improvement. Moreover, protein and mRNA levels of DSS-induced proinflammatory cytokines in colon, including TNF, IL-1β, IL-6, IL-18, IL-17A and IFN-γ, were markedly suppressed by MALT1 inhibitors. The underlying mechanisms for the protective effect of MALT1 inhibitors in DSS-induced colitis may be attributed to its inhibition on NF-κB and NLRP3 inflammasome activation in macrophages. The in vitro study showed that MALT1 inhibitors decreased production of IL-1β/IL-18 in phorbol myristate acetate-differentiated THP-1 cells and bone marrow derived macrophage via suppressing the activation of NF-κB and NLRP3 inflammasome. Taken together, our results demonstrated that inhibition of the protease activity of MALT1 might be a viable strategy to treat inflammatory bowel disease and the NLRP3 inflammasome and NF-κB activation are critical components in MALT1 signaling cascades in this disease model.

Abstract
The aim of this systematic review was to collect and summarise all current data on the cost-effectiveness of biological treatment in ulcerative colitis. A literature search was conducted using the Medline, Embase, Centre for Reviews and Dissemination databases and included all cost-effectiveness analyses comparing biological treatment with any comparator. We identified 277 records of which 10 were included in this review. Eighty percent of identified analyses used quality-adjusted life years (QALY) as a measure of outcome. The most commonly assessed biological agent was infliximab. Half of the eight economic analyses, with QALY as an outcome, showed the cost-effectiveness of biological treatment against the comparator. Incremental cost-effectiveness ratios (ICER) ranged from 15,748 euro to 450,791 euro. The highest ICER values were observed when biologicals were compared with standard care alone. This systematic review revealed that in some cases the biological treatment, despite its clinical effectiveness, is too expensive and exceeds the national threshold value.

Abstract
BACKGROUND AND AIM The preventive effect of intrarectal administration of mouse cathelicidin (mCRAMP) and oral administration of mCRAMP-encoding Lactococcus lactis (N4I) has been shown in murine experimental colitis. It is pivotal to understand the ability of N4I whether it can promote mucosal repair in existing colitis. METHODS Mice with dextran sulfate sodium-induced ulcerative colitis (UC) were treated orally with L. lactis or its transformed strain with or without nisin induction. The body weight, clinical symptoms, and histological changes of colonic tissues were determined. Sulfasalazine was used as a reference drug. Young adult mouse colon cells were used to further elucidate the direct action and possible mechanisms of mCRAMP to promote colonic wound repair. RESULTS Results showed that N4I could improve the clinical symptoms, maintain crypt integrity and preserve mucus-secreting layer in colitis animals. The preparation also could prevent cell death and promote cell proliferation. In contrast, effective dose of sulfasalazine only alleviated clinical symptoms but not the mucosal damage and repair in the colon. In vitro study further showed that mCRAMP could directly promote wound repair by accelerating cell migration but not cell proliferation through the GPCR/MAPK pathway. CONCLUSIONS mCRAMP-encoding L. lactis could be a potential therapeutic preparation better than the traditional anti-inflammatory agent in the treatment of UC.

Abstract
BACKGROUND & AIMS A random biopsy is recommended for surveillance of ulcerative colitis (UC)-associated colorectal cancer. However, a targeted biopsy might be more effective. We conducted a randomized controlled trial to compare rates of neoplasia detection by targeted vs random biopsies in patients with UC. METHODS We performed a study of 246 patients with UC for 7 years or more, seen at 52 institutions in Japan from October 1, 2008 through December 31, 2010. Patients were randomly assigned to the random group (4 random biopsies collected every 10 cm in addition to targeted biopsies, n = 122) or the target group (biopsies collected from locations of suspected neoplasia, n = 124). The primary end point was the number of neoplastic lesions detected in a single surveillance colonoscopy. We estimated the ratio and difference in the mean number of neoplastic lesions between the groups. We also evaluated the non-inferiority between the groups as an exploratory study. A non-inferiority margin of 0.65 (0.13 of 0.20) was considered for the ratio of the mean number of neoplastic lesions between groups. RESULTS The mean number of biopsies found to contain neoplastic tissue per colonoscopy was 0.211 (24 of 114) in the target group and 0.168 (18 of 107) in the random group (ratio of 1.251; 95% confidence interval, 0.679-2.306). The lower limit was above the non-inferiority margin of 0.65. Neoplasias were detected in 11.4% of patients in the target group and 9.3% of patients in the random group (P = .617). Larger numbers of biopsy samples per colonoscopy were collected in the random group (34.8 vs 3.1 in the target group; P < .001), and the total examination time was longer (41.7 vs 26.6 minutes in the target group; P < .001). In the random group, all neoplastic tissues found in random biopsies were collected from areas of the mucosa with a history or presence of inflammation. CONCLUSIONS In a randomized controlled trial, we found that targeted and random biopsies detect similar proportions of neoplasias. However, a targeted biopsy appears to be a more cost-effective method. Random biopsies from areas without any signs of present or past inflammation were not found to contain neoplastic tissues.

Cell surface-anchored syndecan-1 ameliorates intestinal inflammation and neutrophil transmigration in ulcerative colitis. J Cell Mol Med 2016; 21:13-25.

Abstract
Syndecan‐1 (SDC1), with a variable ectodomain carrying heparan sulphate (HS) chains between different Syndecans, participates in many steps of inflammatory responses. In the process of proteolysis, the HS chains of the complete extracellular domain can be shed from the cell surface, by which they can mediate most of SDC1's function. However, the exact impact on SDC1 which anchored on the cell surface has not been clearly reported. In our study, we established the models by transfection with the cleavable resistant SDC1 mutant plasmid, in which SDC1 shedding can be suppressed during stimulation. Role of membrane SDC1 in inflammatory pathway, pro‐inflammatory cytokine secretion as well as neutrophil transmigration, and how suppressing its shedding will benefit colitis were further investigated. We found that the patients suffered ulcerative colitis had high serum SDC1 levels,presented with increased levels of P65, tumour necrosis factor alpha (TNF‐α) and IL‐1β and higher circulating neutrophils. NF‐κB pathway was activated, and secretion of TNF‐α, interleukin‐1beta (IL‐1β), IL‐6 and IL‐8 were increased upon lipopolysaccharide stimuli in intestinal epithelial cells. Syndecan‐1, via its anchored ectodomain, significantly lessened these up‐regulation extents. It also functioned in inhibiting transmigration of neutrophils by decreasing CXCL‐1 secretion. Moreover, SDC1 ameliorated colitis activity and improved histological disturbances of colon in mice. Taken together, we conclude that suppression of SDC1 shedding from intestinal epithelial cells relieves severity of intestinal inflammation and neutrophil transmigration by inactivating key inflammatory regulators NF‐κB, and down‐regulating pro‐inflammatory cytokine expressions. These indicated that compenstion and shedding suppression of cytomembrane SDC1 might be the optional therapy for intestinal inflammation.

Abstract
Purpose Until recently, surgery was the only remaining choice for moderate to severe chronic ulcerative colitis patients who failed standard treatment or when it was not tolerated. Anti-TNFα treatment is a new, non-invasive option for the management of ulcerative colitis. The objective of this study was to assess the cost-effectiveness of induction and maintenance treatment up to 1 year of ulcerative colitis with adalimumab/standard care and standard care alone in Poland. Methods A Markov model was used to estimate the expected costs and effects of adalimumab/standard care and a standard care alone. For each treatment option, the costs and quality adjusted life years were calculated to estimate the incremental cost-utility ratio. The analysis was performed from the perspective of the Polish public payer and society over a 30-year time horizon. Different direct and indirect costs and utility values were assigned to the various model health states. Results The treatment of ulcerative colitis patients with adalimumab/standard care up to 1 year instead of a standard care alone resulted in 0.14 additional years of life with full health (QALYs). The incremental cost-utility ratio of adalimumab/standard care compared to the standard care alone is estimated to be 76,120 €/QALY gained from NHF perspective and 71,457 €/QALY gained from social perspective. Conclusions The biologic treatment of ulcerative colitis patients with adalimumab/standard care is more effective but also more costly compared with standard care alone.

Results The treatment of ulcerative colitis patients with golimumab/standard care instead of a standard care alone resulted in 0.122 additional years of life with full health. The treatment with golimumab/standard care was found to be more expensive than treatment with the standard care alone from the public payer perspective and from social perspective. The incremental cost-utility ratio of golimumab/standard care compared to the standard care alone is estimated to be 391,252 PLN/QALY gained (93,155 €/QALYG) from public payer perspective and 374,377 PLN/QALY gained (89,137 €/QALYG) from social perspective. Conclusions The biologic treatment of ulcerative colitis patients with golimumab/standard care is more effective but also more costly compared with standard care alone.

MicroRNA-16 is putatively involved in the NF-κB pathway regulation in ulcerative colitis through adenosine A2a receptor (A2aAR) mRNA targeting. Sci Rep 2016; 6:30824.

Abstract
MicroRNAs (miRNAs) act as important post-transcriptional regulators of gene expression by targeting the 3′-untranslated region of their target genes. Altered expression of miR-16 is reported in human ulcerative colitis (UC), but its role in the development of the disease remains unclear. Adenosine through adenosine A2a receptor (A2aAR) could inhibit nuclear factor-kappaB (NF-κB) signaling pathway in inflammation. Here we identified overexpression of miR-16 and down-regulation of A2aAR in the colonic mucosa of active UC patients. We demonstrated that miR-16 negatively regulated the expression of the A2aAR at the post-transcriptional level. Furthermore, transfection of miR-16 mimics promoted nuclear translocation of NF-κB p65 protein and expression of pro-inflammatory cytokines, IFN-γ and IL-8 in colonic epithelial cells. Treatment with miR-16 inhibitor could reverse these effects in cells. The A2aAR-mediated effects of miR-16 on the activation of the NF-κB signaling pathway were confirmed by the A2aAR knockdown assay. Our results suggest that miR-16 regulated the immune and inflammatory responses, at least in part, by suppressing the expression of the A2aAR to control the activation of the NF-κB signaling pathway.

Abstract
BACKGROUND AND AIM Recent studies suggest that the anti-inflammatory agent balsalazide (BSZ) and probiotic agent VSL#3 have potential therapeutic benefits for the treatment of patients with inflammatory bowel disease. However, their effectiveness in preventing colitis-associated carcinogenesis (CAC) remains uncertain. The aim of the present study was to determine the chemopreventive effects of BSZ and VSL#3 in the murine azoxymethane (AOM)/dextran sodium sulfate (DSS) model. METHODS C57B/L6J mice were randomly divided into four groups: CAC group, BSZ group, VSL#3 group, and BSZ + VSL#3 group. After 2 weeks, the AOM/DSS model was induced by AOM injection followed by two cycles of 2% DSS. RESULTS During first and second cycles of DSS, the number of F4/80-positive macrophages was significantly lower in the drug-treated groups compared with the CAC group (P < 0.05). At the endpoint, the total numbers of tumors in the drug-treated groups were significantly low compared with the CAC group (P < 0.05), and the drug-treated groups had significantly lower F4/80-positive macrophages in the tumor stroma (P < 0.01). The protein production of macrophage inflammatory protein 1 beta, monocyte chemoattractant protein-1, interleukin (IL)-6, and IL-10 in the colon tissues decreased in concordance with the plasma concentrations of the cytokines (P < 0.05). The drug-treated groups revealed lower expression of p-STAT3 compared with the CAC group. In addition, BCL2 decreased, and BAX increased markedly in the BSZ + VSL#3 group. CONCLUSIONS These results revealed that BSZ and VSL#3 have chemopreventive effects against CAC through IL-6/STAT3 suppression. BSZ and VSL#3 could be suitable options for chemoprevention of colorectal cancer.

Abstract
We evaluated the usefulness of various parameters in predicting the prognosis of ulcerative colitis. The records of 73 patients with ulcerative colitis were examined retrospectively. Patients were divided into two groups according to whether they had received only 5-aminosalicylic acid (5-ASA; n = 26) or glucocorticoids and/or azathioprine with or without 5-ASA ( n = 47). The disease extent, endoscopic activity and ulcerative colitis activity index (UCAI) before therapy were recorded, together with the disease outcome. No statistically significant differences in outcome were observed in relation to therapy group, disease extent or endoscopic activity. UCAI had a significant effect on outcome, however: patients with lower UCAI values were more likely to remain in remission and less likely to require urgent surgery or experience a fatal outcome than those with higher UCAI values. This difference was apparent in both treatment groups. Thus a high pre-treatment UCAI may indicate a worse outcome.

Abstract
STUDY OBJECTIVE To assess the cost-effectiveness of infliximab with standard care (e.g., azathioprine, prednisolone, mesalazine, and 6-mercaptopurine) versus standard care alone for induction and maintenance treatment of patients with ulcerative colitis (UC) in Poland. DESIGN Cost-utility decision analytic model. MEASUREMENTS AND MAIN RESULTS A Markov model was used to estimate the expected costs and effects of infliximab/standard care and standard care alone. For each treatment option, costs and quality-adjusted life-years (QALYs) were calculated to estimate the incremental cost-utility ratio. The target population consisted of a hypothetical cohort of adult patients with moderately to severely active UC who had an inadequate response to standard treatment, including corticosteroids and 6-mercaptopurine or azathioprine, or who were intolerant to or had medical contraindications to such therapies. The analysis was performed from the perspective of the Polish public payer over a 30-year time horizon. The clinical parameters were derived mainly from the Active Ulcerative Colitis Trial (ACT) 1 and ACT 2 and from the Ulcerative Colitis Long-term Remission and Maintenance with Adalimumab (ULTRA) 2 clinical trial. Different costs and utility values were assigned to the various health states in the model; utility values were derived from a previously published study. Treatment of patients who received infliximab/standard care instead of standard care alone resulted in 0.174 additional QALYs. Treatment with infliximab/standard care was found to be more expensive than treatment with standard care alone from the Polish National Health Fund perspective. The incremental cost-utility ratio of infliximab/standard care compared with standard care alone was estimated to be 402,420 Polish zlotys (PLN)/QALY gained (95% confidence interval [CI] 253,936-531,450 PLN/QALY gained), which is equivalent to $106,743 (U.S. dollars)/QALY gained (95% CI $67,357-140,968 [U.S. dollars]/QALY gained). CONCLUSION Treatment with infliximab/standard care instead of standard care alone resulted in additional QALYs but also additional costs. The incremental cost per QALY gained of infliximab/standard care compared with standard care alone exceeded the willingness-to-pay threshold in Poland (equivalent to ~$33,400).

Abstract
Ulcerative colitis (UC) patients are well known to carry a higher risk of developing colorectal dysplasia/cancer. However, it is hard to detect the lesion in the early phase during colonoscopy. This pilot study was conducted to analyze the endoscopic characteristics of neoplastic lesions associated with UC using advanced imaging techniques. This is a retrospective analysis of 15 colorectal neoplastic lesion obtained from 11 UC patients during remission who underwent white-light- and advanced endoscopic imaging techniques, including chromoendoscopy, narrow-band imaging and autofluorescence imaging (AFI), and were treated with surgery. These lesions were analyzed for histology, location, size, shape, color and endoscopic features. The green/red ratio was also assessed to quantify the AFI intensity. All 11 patients had extensive colitis with the median disease duration of 14.0 years. A total of 15 lesions, consisting of 8 high-grade dysplasia and 7 cancer, was mostly located in the distal colon (86.7%, 13/15) with the mean size of 8.6 mm. The shape was protruding in 46.7% (7/15), flat elevated in 40.0% (6/15) and flat in 13.3% (2/15) and the color was red in 60.0% (9/15), same colored in 33.3% (5/15) and discolored in 6.7% (1/15). The lesion predominantly showed Kudo's neoplastic pit pattern in 86.7% (13/15; 5 type IIIL, 7 type IV and 1 type VI) on chromoendoscopy and Sano's neoplastic capillary pattern (type IIIa) in 63.6% (7/11) on narrow-band imaging, but were colored purple as neoplastic lesions in only 37.5% (3/8) on AFI. Of note, the AFI green/red ratio was significantly lower in the neoplastic lesions than UC-involved areas (p=0.00014) and UC-uninvolved areas (p=0.00651) irrespective of the lesion's size and histological type. In conclusion, endoscopic analysis based on advanced imaging, in particular AFI quantitation, may be helpful to detect early stage neoplastic lesions in long standing UC. Large-scale, prospective studies are needed.

Abstract
The aim of the present study was to evaluate the expression of peroxisome proliferator-activated receptor (PPAR)-γ in inflammatory bowel disease (IBD), and to also identify the association between PPAR-γ and the clinical features of patients with IBD. An azoxymethane (AOM)/dextran sodium sulfate (DSS) animal model of colitis-associated neoplasia was established to investigate the protective effect of 5-aminosalicylic acid (5-ASA) and to explore the changes in the expression of PPAR-γ during this process. A total of 66 specimens of colorectal tissue obtained from biopsy performed on IBD patients and 30 healthy control individuals were immunohistochemically stained for PPAR-γ. An AOM/DSS animal model of colitis-associated neoplasia was then established. Reverse transcription quantitative polymerase chain reaction was conducted and it was found that, compared with the control group and patients with Crohn's disease (CD), the expression of PPAR-γ in the intestinal tissue of patients with ulcerative colitis (UC) was significantly decreased (P=0.027 and 0.046, respectively). The expression of PPAR-γ was found to be negatively associated with the disease activity of UC and was not associated with the severity of disease, site of lesions or CD characteristics. Administration of 5-ASA decreased the colitis and tumor burden of colons. The expression level of PPAR-γ in the intestinal tissue was also increased in the AOM/DSS/5-ASA group compared with AOM/DSS group (P<0.001). PPAR-γ is an important factor in the pathogenesis of UC and colitis-associated cancer. The present study found that 5-ASA significantly alleviates the colitis and tumor burden in a mouse model of AOM/DSS-induced colitis-associated neoplasia, and promotes the expression of PPAR-γ in the intestinal tract.

Abstract
Nonresolving inflammation in the intestine predisposes individuals to the development of colitis-associated cancer (CAC). Inflammasomes are thought to mediate intestinal homeostasis, and their dysregulation contributes to inflammatory bowel diseases and CAC. However, few agents have been reported to reduce CAC by targeting inflammasomes. Here we show that the small molecule andrographolide (Andro) protects mice against azoxymethane/dextran sulfate sodium-induced colon carcinogenesis through inhibiting the NLRP3 inflammasome. Administration of Andro significantly attenuated colitis progression and tumor burden. Andro also inhibited NLRP3 inflammasome activation in macrophages both in vivo and in vitro, as indicated by reduced expression of cleaved CASP1, disruption of NLRP3-PYCARD-CASP1 complex assembly, and lower IL1B secretion. Importantly, Andro was found to trigger mitophagy in macrophages, leading to a reversed mitochondrial membrane potential collapse, which in turn inactivated the NLRP3 inflammasome. Moreover, downregulation of the PIK3CA-AKT1-MTOR-RPS6KB1 pathway accounted for Andro-induced autophagy. Finally, Andro-driven inhibition of the NLRP3 inflammasome and amelioration of murine models for colitis and CAC were significantly blocked by BECN1 knockdown, or by various autophagy inhibitors. Taken together, our findings demonstrate that mitophagy-mediated NLRP3 inflammasome inhibition by Andro is responsible for the prevention of CAC. Our data may help guide decisions regarding the use of Andro in patients with inflammatory bowel diseases, which ultimately reduces the risk of CAC.

Abstract
The aim of this systematic review was to collect all current data on indirect costs related to inflammatory bowel disease as well as assessing homogeneity and comparability, and conducting a meta-analysis. Costs were collected using databases from Medline, Embase and Centre for Reviews and Dissemination databases, then average annual cost per patient was calculated and expressed in 2013-rate USD using the consumer price index and purchasing power parity (scenario 1) and then adjusted to specific gross domestic product (scenario 2) to make them comparable. The studies were then included in quantitative synthesis using the meta-analysis and bootstrap methods. This systematic review was carried out and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. From 18 publications, overall annual indirect costs per patient as a result of the quantitative synthesis among all studies eligible for meta-analysis ranged from US$2425.01-US$9622.15 depending on the scenario and model used for analysis. The cost of presenteeism was assessed in only two studies. Considering heterogeneity among all identified studies random-effect model presented the most accurate results of meta-analysis equal to US$7189.27 and US$9622.15 per patient per year for scenario 1 and scenario 2, respectively. This systematic review revealed the existence of a relatively small number of studies that reported on the great economic burden of the disease upon society. A great variety of methodologies and cost components resulted in a very large discrepancy in indirect costs and made meta-analysis difficult to perform, so two scenarios were considered and meta-analysis conducted in subgroups to make data more comparable.

Abstract
Sleep deprivation (SD) is an epidemic phenomenon in modern countries, and its harmful effects are well known. SD acts as an aggravating factor in inflammatory bowel disease. Melatonin is a sleep-related neurohormone, also known to have antioxidant and anti-inflammatory effects in the gastrointestinal tract; however, the effects of melatonin on colitis have been poorly characterized. Thus, in this study, we assessed the measurable effects of SD on experimental colitis and the protective effects of melatonin. For this purpose, male imprinting control region (ICR) mice (n=24) were used; the mice were divided into 4 experimental groups as follows: the control, colitis, colitis with SD and colitis with SD and melatonin groups. Colitis was induced by the administration of 5% dextran sulfate sodium (DSS) in the drinking water for 6 days. The mice were sleep-deprived for 3 days. Changes in body weight, histological analyses of colon tissues and the expression levels of pro-inflammatory cytokines and genes were evaluated. SD aggravated inflammation and these effects were reversed by melatonin in the mice with colitis. In addition, weight loss in the mice with colitis with SD was significantly reduced by the injection of melatonin. Treatment with melatonin led to high survival rates in the mice, in spite of colitis with SD. The levels of pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, IL-17, interferon-γ and tumor necrosis factor-α, in the serum of mice were significantly increased by SD and reduced by melatonin treatment. The melatonin-treated group showed a histological improvement of inflammation. Upon gene analysis, the expression of the inflammatory genes, protein kinase Cζ (PKCζ) and calmodulin 3 (CALM3), was increased by SD, and the levels decreased following treatment with melatonin. The expression levels of the apoptosis-related inducible nitric oxide synthase (iNOS) and wingless-type MMTV integration site family, member 5A (Wnt5a) genes was decreased by SD, but increased following treatment with melatonin. Treatment with melatonin reduced weight loss and prolonged survival in mice with colitis with SD. Melatonin exerted systemic anti-inflammatory effects. Gene analysis revealed a possible mechanism of action of melatonin in inflammation and sleep disturbance. Thus, melatonin may be clinically applicable for patients with inflammatory bowel disease, particulary those suffering from sleep disturbances.

Abstract
OBJECTIVES For the treatment of inflammatory bowel disease, the development of pH responsive modified release dosage forms is one of the most common approaches to achieve targeted drug delivery. In this study, the dissolution behaviour of eight different modified release (MR) products containing 800 mg mesalazine was investigated. METHODS The performance of the products was compared under simulated fasted state conditions using the paddle apparatus as well as the dissolution stress test device mimicking mechanical stress events of bio-relevant intensity. KEY FINDINGS The dissolution behaviour of the eight tested different pH-responsive MR tablets containing 800 mg mesalazine was dependent on the test conditions. Phases of mechanical stress with physiological intensity influenced the dissolution characteristics and caused in some cases accelerated drug release indicating possible dose dumping. CONCLUSION The study demonstrates that besides the investigation of the pH dependency of drug release, the characterisation of the mechanical robustness of the dosage forms is an essential factor determining the dissolution characteristics of such pH-dependent targeted modified release tablets. The susceptibility of 800 mg mesalazine MR tablets towards mechanical stress may be one reason for undesired drug delivery in vivo.

Abstract
In the present study, the effect of asiatic acid, a natural triterpenoid compound, on murine experimental colitis induced by dextran sulfate sodium (DSS) and its possible mechanism were examined in vivo and vitro. Oral administration of asiatic acid dose-dependently attenuated the loss of body weight and shortening of colon length induced by DSS. The disease activity index, histopathologic scores of musco and myeloperoxidase activity were also significantly reduced by asiatic acid treatment. Protein and mRNA levels of DSS-induced pro-inflammatory cytokines in colon, including TNF-α, IL-1β, IL-6 and IFN-γ, were markedly suppressed by asiatic acid. At the same time, decreased activation of caspase-1 in peritoneal macrophages was detected in asiatic acid-treated mice, which suggested that the NLRP3 inflammasome activation was suppressed. In addition, we also found that asiatic acid dose-dependently inhibited IL-1β secretion, caspase-1 activation as well as inflammasome assembling in vitro. Furthermore, the mechanism of asiatic acid was related to the inhibition of mitochondrial reactive oxygen species generation and prevention of mitochondrial membrane potential collapse. Taken together, our results demonstrate the ability of asiatic acid to inhibit NLRP3 inflammasome activation and its potential usage in the treatment of inflammatory bowel diseases.

Abstract
The present review briefly describes the nature, type and pathogenesis of ulcerative colitis, and explores the potential use of peptides and proteins in the treatment of inflammatory bowel disease, especially ulcerative colitis. Intestinal absorption and the barrier mechanism of peptide and protein drugs are also discussed, with special emphasis on various strategies which make these drugs better therapeutics having high specificity, potency and molecular targeting ability. However, the limitation of such therapeutics are oral administration, poor pharmacokinetic profile and decreased bioavailability. The recent findings illustrated in this review will be helpful in designing the peptide/protein drugs as a promising treatment of choice for ulcerative colitis.

Abstract
This study tests the hypothesis that prediagnostic serum levels of 20 cancer-associated inflammatory biomarkers correlate directly with future development of head and neck, esophageal, and lung cancers in a high-risk prospective cohort. This is a nested case-control pilot study of subjects enrolled in the Golestan Cohort Study, an ongoing epidemiologic project assessing cancer trends in Golestan, Iran. We measured a panel of 20 21 cytokines, chemokines, and inflammatory molecules using Luminex technology in serum samples collected 2 or more years before cancer diagnosis in 78 aerodigestive cancer cases and 81 controls. Data was analyzed using Wilcoxon rank sum test, odds ratios, receiver operating characteristic areas of discrimination, and multivariate analysis. Biomarkers were profoundly and globally elevated in future esophageal and lung cancer patients compared to controls. Odds ratios were significant for association between several biomarkers and future development of esophageal cancer, including interleukin-1Rα (IL-1Ra; 35.9), interferon α2 (IFN-a2; 34.0), fibroblast growth factor-2 (FGF-2; 17.4), and granulocyte/macrophage colony-stimulating factor (GM-CSF; 17.4). The same pattern was observed among future lung cancer cases for G-CSF (27.7), GM-CSF (13.3), and tumor necrosis factor-α (TNF-a; 8.6). By contrast, the majority of biomarkers studied showed no significant correlation with future head and neck cancer development. This study provides the first direct evidence that multiple inflammatory biomarkers are coordinately elevated in future lung and esophageal cancer patients 2 or more years before cancer diagnosis.

Abstract
BACKGROUND C-reactive protein (CRP) is used as a biomarker of ulcerative colitis (UC) activity, but CRP levels are sometimes insufficient to reflect UC activity. Therefore, a simple noninvasive biomarker assay with sufficient sensitivity and specificity to accurately reflect UC activity is desired. Since prostaglandin E2 production and colonic inflammation are associated, we evaluated whether prostaglandin E-major urinary metabolite (PGE-MUM) can be used as such a biomarker. METHODS Patients with UC (n = 99) were enrolled from March 2011 to February 2012. UC activity was evaluated using the simple clinical colitis activity index in 99 patients, Mayo endoscopic scoring (Mayo) in 79 patients, and Matts' grading (Matts) in 64 patients. PGE-MUM levels were measured by radioimmunoassay kit and compared against CRP levels as a control. RESULTS Both PGE-MUM and CRP levels correlated with UC activity (P < 0.01). Areas under the receiver operating characteristic curves of simple clinical colitis activity index, Mayo, and Matts for PEG-MUM were each higher than for CRP (0.93 > 0.73, 0.90 > 0.77, and 0.89 > 0.75, respectively). In multivariate logistic regression models, PGE-MUM was a significant independent predictor of histologic remission (sensitivity/specificity, 0.82/0.82) when the cutoff value was set to 17.0 μg/g creatinine, but CRP was not (0.69/0.69) (P < 0.01). CONCLUSIONS Compared with CRP level, PGE-MUM level demonstrated better sensitivity for reflecting UC activity, especially in cases of histologic inflammation, and thus seems to be a better evaluator of mucosal healing. Because this method is simple, quick, and noninvasive, PGE-MUM seems to be a useful biomarker of UC.

Melatonin attenuates dextran sodium sulfate induced colitis with sleep deprivation: possible mechanism by microarray analysis. Dig Dis Sci 2014; 59:1134-41. [PMID: 24429513 DOI: 10.1007/s10620-013-3013-2] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2013] [Accepted: 12/20/2013] [Indexed: 12/12/2022]
Abstract
BACKGROUND Inflammatory bowel disease is a chronic inflammatory condition of the gastrointestinal tract. It can be aggravated by stress, like sleep deprivation, and improved by anti-inflammatory agents, like melatonin. We aimed to investigate the effects of sleep deprivation and melatonin on inflammation. We also investigated genes regulated by sleep deprivation and melatonin. METHODS In the 2% DSS induced colitis mice model, sleep deprivation was induced using modified multiple platform water bath. Melatonin was injected after induction of colitis and colitis with sleep deprivation. Also mRNA was isolated from the colon of mice and analyzed via microarray and real-time PCR. RESULTS Sleep deprivation induced reduction of body weight, and it was difficult for half of the mice to survive. Sleep deprivation aggravated, and melatonin attenuated the severity of colitis. In microarrays and real-time PCR of mice colon tissues, mRNA of adiponectin and aquaporin 8 were downregulated by sleep deprivation and upregulated by melatonin. However, mRNA of E2F transcription factor (E2F2) and histocompatibility class II antigen A, beta 1 (H2-Ab1) were upregulated by sleep deprivation and downregulated by melatonin. CONCLUSION Melatonin improves and sleep deprivation aggravates inflammation of colitis in mice. Adiponectin, aquaporin 8, E2F2 and H2-Ab1 may be involved in the inflammatory change aggravated by sleep deprivation and attenuated by melatonin.

Abstract
BACKGROUND: The role of the CARD15 gene 3020insC frameshift mutation in the pathogenesis of inflammatory bowel diseases (IBD) investigated without a definitive conclusion. The incidence of this mutation in Turkish patients with Crohn’s disease is not known.OBJECTIVE: We investigated whether the CARD15/NOD2 3020insC frameshift mutation is a risk factor for patients with inflammatory bowel disease in Black Sea Region population in Turkey.METHODS: We studied 3020insC mutation of CARD15/NOD2 gene by allele-specific multiplex PCR in 69 patients with IBD (18 Crohn’s disease [CD] and 51 ulcerative colitis [UC]) and 101 ethnically matched healthy controls.RESULTS: CARD15/NOD2 3020insC frameshift mutation was positive in 7/18 (38.8 %), 13/51 (25.5 %), and 4/101 (4 %) of CD, UC, and healthy control groups, respectively. None of the controls or patients with Crohn’s disease and ulcerative colitis was homozygous for this mutations.CONCLUSION: This study is to investigate a relation between CARD15/NOD2 3020insC frameshift mutation and in patients with IBD in the Turkish Population. C-insertion frameshift mutation is a major contributor to the susceptibility to both CD and UC, but it is not specific to patients with CD in Turkish population.

Abstract
Eotaxin-1 (CCL-11) is a potent eosinophil chemoattractant that is considered a major contributor to tissue eosinophilia. Elevated eotaxin-1 levels have been described in various pathologic conditions, ranging from airway inflammation, to Hodgkin lymphoma, obesity and coronary artery disease. The main receptor for eotaxin-1 is CCR3; however, recent evidence indicates that eotaxin-1 may also bind to other receptors expressed by various cell types, suggesting a more widespread regulatory role for eotaxin-1 beyond the recruitment of eosinophils. Eotaxin-1 is also strongly associated with various gastrointestinal (GI) disorders. Although the etiology of inflammatory bowel disease (IBD) is still unknown, eotaxin-1 may play a key role in the development of mucosal inflammation. In this review, we summarize the biological context and effects of eotaxin-1, as well as its potential role as a therapeutic target, with a special focus on gastrointestinal inflammation.

Abstract
BACKGROUND MicroRNAs (miRNAs) are important posttranscriptional regulators of gene expression. The precise role of miRNAs in ulcerative colitis (UC) is not completely understood. The purpose of this study was to identify miRNAs that are induced in patients with active UC and to assess the effect of miR-155 on improving intestinal inflammation. METHODS The miRNA profiles in patients with active UC (n = 20) and healthy subjects (n = 16) were examined using miRNA microarrays. miR-155 upregulation was confirmed by quantitative RT-PCR. Regulation of the target gene FOXO3a expression by miR-155 was assessed using luciferase reporter construct assays and miR-155 mimic or inhibitor transfections. The effects of FOXO3a or miR-155 on IκBα or IL-8 were detected by Western blot or enzyme-linked immunosorbent assay in HT29 cells, respectively. RESULTS We identified 68 miRNAs that were differentially expressed (33 upregulated and 35 downregulated) in patients with active UC compared with healthy controls. One of the upregulated miRNAs in the UC tissue was miR-155 (1.22-fold, P < 0.03), which plays a key role in the regulation of inflammatory pathways. In patients with active UC, miR-155 was significantly upregulated, and the expression of FOXO3a dramatically decreased. Luciferase reporter assays demonstrated that miR-155 directly targets FOXO3a and affects the protein expression of FOXO3a in HT29 cells. Moreover, silenced FOXO3a and the overexpression of miR-155 increased the levels of IL-8 in TNF-α-treated HT29 cells by suppressing the inhibitory IκBα. CONCLUSIONS miR-155 appears to play a role in the intestinal inflammation of patients with active UC by downregulating the expression of FOXO3a. This process may activate the nuclear factor kappa B signaling pathway.

Abstract
5-aminosalicylic acid (5-ASA) is drug of choice for the treatment of ulcerative colitis (UC). In this study, the efficacy of topical versus oral 5-ASA for the treatment of UC was examined as well as the action mechanism of this medication. A flexible tube was inserted into the rat cecum to establish a topical administration model of 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced UC. A total of 60 rats were divided into sham operation group (receiving an enema of 0.9% saline solution instead of the TNBS solution via the tube), model group, topical 5-ASA group, oral Etiasa group (a release agent of mesalazine used as positive control) and oral 5-ASA group (n=12 each). Different treatments were administered 1 day after UC induction. The normal saline (2 mL) was instilled twice a day through the tube in the sham operation group and model group. 5-ASA was given via the tube in the topical 5-ASA group (7.5 g/L, twice per day, 100 mg/kg), and rats in the oral Etiasa group and oral 5-ASA group intragastrically received Etiasa (7.5 g/L, twice per day, 100 mg/kg) and 5-ASA (7.5 g/L, twice per day, 100 mg/kg), respectively. The body weight was recorded every day. After 7 days of treatment, blood samples were drawn from the heart to harvest the sera. Colonic tissues were separated and prepared for pathological and related molecular biological examinations. The concentrations of 5-ASA were detected at different time points in the colonic tissues, feces and sera in different groups by using the high pressure liquid chromatography (HPLC). The results showed that the symptoms of acute UC, including bloody diarrhea and weight loss, were significantly improved in topical 5-ASA-treated rats. The colonic mucosal damage, both macroscopical and histological, was significantly relieved and the myeloperoxidase activity was markedly decreased in rats topically treated with 5-ASA compared with those treated with oral 5-ASA or Etiasa. The mRNA and protein expression of IL-1β, IL-6, and TNF-α was down-regulated in the colonic tissue of rats topically treated with 5-ASA, significantly lower than those from rats treated with oral 5-ASA or Etiasa. The concentrations of 5-ASA in the colonic tissue were significantly higher in the topical 5-ASA group than in the oral 5-ASA and oral Etiasa groups. It was concluded that the topical administration of 5-ASA can effectively increase the concentration of 5-ASA in the colonic tissue, decrease the expression of proinflammatory cytokines, alleviate the colonic pathological damage and improve the symptoms of TNBS-induced acute UC in rats.

Glutamate microinjection into the hypothalamic paraventricular nucleus attenuates ulcerative colitis in rats. Acta Pharmacol Sin 2014; 35:185-94. [PMID: 24362327 DOI: 10.1038/aps.2013.140] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2013] [Accepted: 08/28/2013] [Indexed: 12/12/2022] Open
Abstract
AIM To investigate the effects of glutamate microinjection into hypothalamic paraventricular nucleus (PVN) on ulcerative colitis (UC) in rats and to explore the relevant mechanisms. METHODS 2,4,6-Trinitrobenzenesulfonic acid (100 mg/kg in 50% ethanol) was instilled into the colon of adult male SD rats to induce UC. A colonic damage score (CDS) was used to indicate the severity of the colonic mucosal damage. The pathological changes in the colonic mucosa were evaluated using immunohistochemistry, Western blotting, biochemical analyses or ELISA. Ten minutes before UC induction, drugs were microinjected into the relevant nuclei in rat brain to produce chemical stimulation or chemical lesion. RESULTS Microinjection of glutamate (3, 6 and 12 μg) into the PVN dose-dependently decreased the CDS in UC rats. This protective effect was eliminated after kainic acid (0.3 μg) was microinjected into PVN or into the nucleus tractus solitarius (NTS) that caused chemical lesion of these nuclei. This protective effect was also prevented when the AVP-V1 receptor antagonist DPVDAV (200 ng) was microinjected into the NTS. The discharge frequency of the vagus was markedly decreased following microinjection of glutamate into the PVN. Microinjection of glutamate into the PVN in UC rats significantly increased the cell proliferation and anti-oxidant levels, and decreased the apoptosis and Bax and caspase 3 expression levels and reduced the pro-inflammatory factors in the colonic mucosa. CONCLUSION The activation of hypothalamic PVN exerts protective effects against UC, which is mediated by the NTS and vagus. The effects may be achieved via anti-oxidative, anti-apoptotic, and anti-inflammatory factors.
