PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 132:155868. [PMID: 39032278 DOI: 10.1016/j.phymed.2024.155868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 07/02/2024] [Accepted: 07/08/2024] [Indexed: 07/23/2024]
Abstract
BACKGROUND Linderae Radix (LR), the dried root of Lindera aggregata (Sims) Kosterm., is a traditional Chinese herbal medicine that has been used for thousands of years for promoting Qi circulation, soothing the liver, and treating diarrhea and dysentery. Previous studies have found that ethanol extract of LR plays an anti-ulcerative colitis (UC) role by regulating Th17/ Treg balance. Water extract is the classic clinical application form of LR, but the effect of water extract of LR (LRWE) on UC and its underlying mechanism is still unclear. PURPOSE Purpose: UC is a gastrointestinal disease characterized by intestinal inflammation, mucosal injury, and fibrosis, and it is one of the high-risk factors for colon cancer. However, there is still a lack of remedies with satisfactory effects. This study aimed to investigate the efficacy and the potential mechanism of LRWE against UC. METHODS LRWE samples were prepared using a reflux extraction method. Colitis in mice was induced by administering 2.5 % DSS water solution to evaluate the therapeutic effect of LRWE by assessing disease activity score, colon length, and fecal morphology. H&E staining, TEM, Masson staining, and AB-PAS staining were applied to observe histopathological changes in the colon tissues. Differentially expressed genes in colon tissues were analyzed by transcriptomics. Cell apoptosis was detected by TUNEL staining. The expression of inflammatory factors such as IL-6 and IL-1β, as well as the expression of p-STAT1, p-JAK2, p-STAT3, Bax, and Bcl-2, were detected by immunofluorescence and immunohistochemistry. The expression of occludin, Bcl-2, Bax, and JAK/STAT signaling pathway-related vital proteins were quantified by Western blot (WB). RESULTS LRWE alleviated body weight loss, colon shortening, DAI scores, pathological changes, and ultrastructural features of colon tissue in mice with colitis. It also inhibited the increase of pro-inflammatory cytokines (such as TNF-α, IL-6, and IL-1β) and increased IL-10 levels. Additionally, it protected the intestinal barrier by upregulating the expression of Occludin and Mucin-2. Mechanistically, LRWE could inhibit the activation of JAK-STAT signaling pathway by reducing the protein expression of p-JAK2, p-STAT3, p-STAT1, Bcl2, and Bax, thus reducing the inflammatory responses and inhibiting cell apoptosis. CONCLUSION LRWE has a protective effect on DSS-induced UC. This effect is related to the inhibition of the JAK-STAT signaling pathway, the improvement of intestinal inflammation, and the reduction of intestinal epithelial cell apoptosis.

[PMID: 38855111 PMCID: PMC11157060 DOI: 10.3389/fimmu.2024.1363457] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Accepted: 05/13/2024] [Indexed: 06/11/2024] Open
Abstract
Introduction Human infections with the food-borne enteropathogen Campylobacter jejuni are responsible for increasing incidences of acute campylobacteriosis cases worldwide. Since antibiotic treatment is usually not indicated and the severity of the enteritis directly correlates with the risk of developing serious autoimmune disease later-on, novel antibiotics-independent intervention strategies with non-toxic compounds to ameliorate and even prevent campylobacteriosis are utmost wanted. Given its known pleiotropic health-promoting properties, curcumin constitutes such a promising candidate molecule. In our actual preclinical placebo-controlled intervention trial, we tested the anti-microbial and anti-inflammatory effects of oral curcumin pretreatment during acute experimental campylobacteriosis. Methods Therefore, secondary abiotic IL-10-/- mice were challenged with synthetic curcumin via the drinking water starting a week prior oral C. jejuni infection. To assess anti-pathogenic, clinical, immune-modulatory, and functional effects of curcumin prophylaxis, gastrointestinal C. jejuni bacteria were cultured, clinical signs and colonic histopathological changes quantitated, pro-inflammatory immune cell responses determined by in situ immunohistochemistry and intestinal, extra-intestinal and systemic pro-inflammatory mediator measurements, and finally, intestinal epithelial barrier function tested by electrophysiological resistance analysis of colonic ex vivo biopsies in the Ussing chamber. Results and discussion Whereas placebo counterparts were suffering from severe enterocolitis characterized by wasting symptoms and bloody diarrhea on day 6 post-infection, curcumin pretreated mice, however, were clinically far less compromised and displayed less severe microscopic inflammatory sequelae such as histopathological changes and epithelial cell apoptosis in the colon. In addition, curcumin pretreatment could mitigate pro-inflammatory innate and adaptive immune responses in the intestinal tract and importantly, rescue colonic epithelial barrier integrity upon C. jejuni infection. Remarkably, the disease-mitigating effects of exogenous curcumin was also observed in organs beyond the infected intestines and strikingly, even systemically given basal hepatic, renal, and serum concentrations of pro-inflammatory mediators measured in curcumin pretreated mice on day 6 post-infection. In conclusion, the anti-Campylobacter and disease-mitigating including anti-inflammatory effects upon oral curcumin application observed here highlight the polyphenolic compound as a promising antibiotics-independent option for the prevention from severe acute campylobacteriosis and its potential post-infectious complications.

Curr Genomics 2024; 25:120-139. [PMID: 38751599 PMCID: PMC11092913 DOI: 10.2174/0113892029280454240214072212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 01/12/2024] [Accepted: 02/01/2024] [Indexed: 05/18/2024] Open
Abstract
Background Calebin-A is a minor phytoconstituent of turmeric known for its activity against inflammation, oxidative stress, cancerous, and metabolic disorders like Non-alcoholic fatty liver disease(NAFLD). Based on bioinformatic tools. Subsequently, the details of the interaction of critical proteins with Calebin-A were investigated using the molecular docking technique. Methods We first probed the intersection of genes/ proteins between NAFLD and Calebin-A through online databases. Besides, we performed an enrichment analysis using the ClueGO plugin to investigate signaling pathways and gene ontology. Next, we evaluate the possible interaction of Calebin-A with significant hub proteins involved in NAFLD through a molecular docking study. Results We identified 87 intersection genes Calebin-A targets associated with NAFLD. PPI network analysis introduced 10 hub genes (TP53, TNF, STAT3, HSP90AA1, PTGS2, HDAC6, ABCB1, CCT2, NR1I2, and GUSB). In KEGG enrichment, most were associated with Sphingolipid, vascular endothelial growth factor A (VEGFA), C-type lectin receptor, and mitogen-activated protein kinase (MAPK) signaling pathways. The biological processes described in 87 intersection genes are mostly concerned with regulating the apoptotic process, cytokine production, and intracellular signal transduction. Molecular docking results also directed that Calebin-A had a high affinity to bind hub proteins linked to NAFLD. Conclusion Here, we showed that Calebin-A, through its effect on several critical genes/ proteins and pathways, might repress the progression of NAFLD.

Abstract
BACKGROUND Radiation triggers salivary gland damage and excess iron accumulates in tissues induces cell injury. Flavonoids are found in some fruits and are utilized as potent antioxidants and radioprotective agents. This study aimed to evaluate the antioxidant and anti-inflammatory effects of hesperidin and rutin on gamma radiation and iron overload induced submandibular gland (SMG) damage and to evaluate their possible impact on mitigating the alteration in mTOR signaling pathway and angiogenesis. METHODS Forty-eight adult male Wistar albino rats were randomly assigned to six groups: group C received a standard diet and distilled water; group H received hesperidin at a dose of 100 mg/kg; four times a week for four weeks; group U received rutin at a dose of 50 mg/kg; three times a week for three weeks; group RF received a single dose (5 Gy) of gamma radiation followed by iron at a dose of 100 mg/kg; five times a week for four weeks; group RFH received radiation and iron as group RF and hesperidin as group H; group RFU received radiation and iron as group RF and rutin as group U. SMG specimens from all groups were removed at the end of the experiment; and some were used for biochemical analysis, while others were fixed for histological and immunohistochemical examination. RESULTS In the RF group, several genes related to antioxidants (Nrf-2 and SOD) and DNA damage (BRCA1) were significantly downregulated, while several genes related to inflammation and angiogenesis (TNFα, IL-1β and VEGF) and the mTOR signaling pathway (PIK3ca, AKT and mTOR) were significantly upregulated. Acinar cytoplasmic vacuolation, nuclear pyknosis, and interacinar hemorrhage with distinct interacinar spaces were observed as histopathological changes in SMGs. The duct system suffered significant damage, eventually degenerating entirely as the cells were shed into the lumina. VEGF and NF-κB were also significantly overexpressed. Hesperidin and rutin cotreatment generated partial recovery as indicated by significant upregulation of Nrf-2, SOD and BRCA1 and considerable downregulation of TNF-α, IL-1β, VEGF, PIK3ca, AKT, and mTOR. Although some acini and ducts continued to deteriorate, most of them had a normal appearance. There was a notable decrease in the expression of VEGF and NF-κB. CONCLUSIONS In γ-irradiated rats with iron overload, the administration of hesperidin and rutin may mitigate salivary gland damage.

Abstract
Inflammatory bowel disease (IBD) is a chronic, relapsing gastrointestinal (GI) disorder characterized by intestinal inflammation. The etiology of IBD is multifactorial and results from a complex interplay between mucosal immunity, environmental factors, and host genetics. Future therapeutics for GI disorders, including IBD, that are driven by oxidative stress require a greater understanding of the cellular and molecular mechanisms mediated by reactive oxygen species (ROS). In the GI tract, oxidative stressors include infections and pro-inflammatory responses, which boost ROS generation by promoting the production of pro-inflammatory cytokines. Nuclear factor kappa B (NF-κB) and nuclear factor erythroid 2-related factor 2 (Nrf2) represent two important signaling pathways in intestinal immune cells that regulate numerous physiological processes, including anti-inflammatory and antioxidant activities. Natural antioxidant compounds exhibit ROS scavenging and increase antioxidant defense capacity to inhibit pro-oxidative enzymes, which may be useful in IBD treatment. In this review, we discuss various polyphenolic substances (such as resveratrol, curcumin, quercetin, green tea flavonoids, caffeic acid phenethyl ester, luteolin, xanthohumol, genistein, alpinetin, proanthocyanidins, anthocyanins, silymarin), phenolic compounds including thymol, alkaloids such as berberine, storage polysaccharides such as tamarind xyloglucan, and other phytochemicals represented by isothiocyanate sulforaphane and food/spices (such as ginger, flaxseed oil), as well as antioxidant hormones like melatonin that target cellular signaling pathways to reduce intestinal inflammation occurring with IBD.

Abstract
Apple is an important dietary agent for human and apple polyphenols (AP) are the main secondary metabolites of apples. In this study, the protective effects of AP on hydrogen peroxide (H2O2)-induced oxidative stress damage in human colon adenocarcinoma Caco-2 cells were investigated by cell viability, oxidative stress change as well as cell apoptosis. Pre-adding AP could significantly increase the survival rate of H2O2-treated Caco-2 cells. Besides, the activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and catalase (CAT) were elevated. While the malondialdehyde (MDA) content which is the major oxidant products of polyunsaturated fatty acids (PUFA) reduced after AP treatment. In addition, AP also suppressed the emergence of DNA fragment and decreased the expression of apoptosis-related protein Caspase-3. These results demonstrated that AP could ameliorate H2O2-induced oxidative stress damage in Caco-2 cells, which could serve as a reference for further studies of apple natural active products and deep study of the anti-oxidative stress mechanism.

Abstract
Ulcerative Colitis (UC) is a disease that negatively affects quality of life and is associated with sustained oxidative stress, inflammation and intestinal permeability. Vitamin D and Curcumin; It has pharmacological properties beneficial to health, including antioxidant and anti-inflammatory properties. Our study investigates the role of Vitamin D and Curcumin in acetic acid-induced acute colitis model. To investigate the effect of Vitamin D and Curcumin, Wistar-albino rats were given 0.4 mcg/kg Vitamin D (Post-Vit D, Pre-Vit D) and 200 mg/kg Curcumin (Post-Cur, Pre-Cur) for 7 days and acetic acid was injected into all rats except the control group. Our results; colon tissue TNF-α, IL-1β, IL-6, IFN-γ and MPO levels were found significantly higher and Occludin levels were found significantly lower in the colitis group compared to the control group (p < 0.05). TNF-α and IFN-γ levels decreased and Occludin levels increased in colon tissue of Post-Vit D group compared to colitis group (p < 0.05). IL-1β, IL-6 and IFN-γ levels were decreased in colon tissue of Post-Cur and Pre-Cur groups (p < 0.05). MPO levels in colon tissue decreased in all treatment groups (p < 0.05). Vitamin D and Curcumin treatment significantly reduced inflammation and restored the normal histoarchitecture of the colon. From the present study findings, we can conclude that Vitamin D and Curcumin protect the colon from acetic acid toxicity with their antioxidant and anti-inflammatory potential.

Abstract
Dextran is by far one of the most interesting non-toxic, bio-compatible macromolecules, an exopolysaccharide biosynthesized by lactic acid bacteria. It has been extensively used as a major component in many types of drug-delivery systems (DDS), which can be submitted to the next in-vivo testing stages, and may be proposed for clinical trials or pharmaceutical use approval. An important aspect to consider in order to maintain high DDS' biocompatibility is the use of dextran obtained by fermentation processes and with a minimum chemical modification degree. By performing chemical modifications, artefacts can appear in the dextran spatial structure that can lead to decreased biocompatibility or even cytotoxicity. The present review aims to systematize DDS depending on the dextran type used and the biologically active compounds transported, in order to obtain desired therapeutic effects. So far, pure dextran and modified dextran such as acetalated, oxidised, carboxymethyl, diethylaminoethyl-dextran and dextran sulphate sodium, were used to develop several DDSs: microspheres, microparticles, nanoparticles, nanodroplets, liposomes, micelles and nanomicelles, hydrogels, films, nanowires, bio-conjugates, medical adhesives and others. The DDS are critically presented by structures, biocompatibility, drugs loaded and therapeutic points of view in order to highlight future therapeutic perspectives.

Abstract
The environmental factors and genetic vulnerability trigger the inflammatory bowel diseases (IBDs) such as ulcerative colitis and Crohn's disease. Furthermore, the oxidative stress and inflammatory cytokines have been implicated in the aggravation of the IBDs. The aim of the present study was to investigate the effect of N-(benzylidene)-2-((2-hydroxynaphthalen-1-yl)diazenyl)benzohydrazides (NCHDH and NTHDH) compounds against the DSS-induced colitis in mice. The colitis was induced by 5% dextran sulfate sodium (DSS) dissolved in normal saline for 5 days. The effect of the NCHDH and NTHDH on the behavioral, biochemical, histological, and immunohistological parameters was assessed. The NCHDH and NTHDH treatment improved the behavioral parameters such as food intake, disease activity index, and diarrhea score significantly compared to DSS control. The NCHDH and NTHDH treatments significantly increased the antioxidant enzymes, whereas oxidative stress markers were markedly reduced. Similarly, the NCHDH and NTHDH treatments significantly suppressed the activity of nitric oxide (NO), myeloperoxidase (MPO), and eosinophil peroxidase (EPO). The histological studies showed a significant reduction in inflammation, immune cell infiltration, and fibrosis in the NCHDH- and NTHDH-treated groups. The immunohistochemical results demonstrated that NCHDH and NTHDH treatments markedly increase the expression level of Nrf2, HO-1 (hemeoxygenase-1), TRX (thioredoxin reductase), and IκB compared to the DSS-induced group. In the same way, the NCHDH and NTHDH significantly reduced the NF-κB and COX-2 (cyclooxygenase-2) expression levels. The NCHDH and NTHDH treatment significantly improved the symptoms associated with colitis via inducing antioxidants and attenuating oxidative stress markers.

Abstract
Chronic diseases including cancer have high case numbers as well as mortality rates. The efficient treatment of chronic diseases is a major ongoing medical challenge worldwide, because of their complexity and many inflammatory pathways such as JNK, p38/MAPK, MEK/ERK, JAK/STAT3, PI3K and NF-κB among others being implicated in their pathogenesis. Together with the versatility of chronic disease classical mono-target therapies are often insufficient. Therefore, the anti-inflammatory as well as anti-cancer capacities of polyphenols are currently investigated to complement and improve the effect of classical anti-inflammatory drugs, chemotherapeutic agents or to overcome drug resistance of cancer cells. Currently, research on Calebin A, a polyphenolic component of turmeric (Curcuma longa), is becoming of growing interest with regard to novel treatment strategies and has already been shown health-promoting as well as anti-tumor properties, including anti-oxidative and anti-inflammatory effects, in diverse cancer cells. Within this review, we describe already known anti-inflammatory activities of Calebin A via modulation of NF-κB and its associated signaling pathways, linked with TNF-α, TNF-β and COX-2 and further summarize Calebin A’s tumor-inhibiting properties that are known up to date such as reduction of cancer cell viability, proliferation as well as metastasis. We also shed light on possible future prospects of Calebin A as an anti-cancer agent.

Abstract
Probiotics are microorganisms that can benefit host health when ingested in a live state, and lactic acid bacteria are the most common type. Among fungi, Saccharomyces boulardii (SB) is the only strain known to have a probiotic function with beneficial effects on colitis; however, information on other probiotic yeast strains is limited. Therefore, this study aimed to discover yeast strains expressing intestinal anti-inflammatory activities by exhibiting probiotic properties in dextran sodium sulfate (DSS)-induced colitis mice model. Nuruk (Korean traditional fermentation starter) containing various microbial strains was used as a source for yeast strains, and S. cerevisiae 28-7 (SC28-7) strain was selected with in vitro and in vivo characteristics to enable survival in the intestines. After 14 days of pretreatment with the yeast strains, DSS was co-administered for six days to induce colitis in mice. The results revealed that the disease activity index score was lowered by SC28-7 treatment compared to the DSS group, and the colon length and weight/length ratio were recovered in a pattern similar to that of the normal group. SC28-7 administration significantly reduced the secretion of pro-inflammatory cytokines in the serum and modified the mRNA expression of inflammatory cytokines (interleukin-1β, transforming growth factor-β, and interferon-γ) and proteins involved in gut barrier functions (mucin 2, mucin 3, zonula occludens-1, and occludin) in colon tissues. These results indicate that SC28-7 attenuates DSS-induced colon damage and inflammation, supporting its future use as a probiotic yeast for treating and preventing intestinal inflammatory diseases such as inflammatory bowel disease.

Abstract
Curcumin is extracted from the rhizomes of Curcuma longa L. It is now widely used in food processing, cosmetics, dyes, etc. Current researching indicates that curcumin has high medical value, including anti-inflammatory, antioxidant, anti-tumor, anti-apoptotic, anti-fibrosis, immune regulation and other effects, and can be used to treat a variety of diseases. Inflammatory bowel disease (IBD) is a nonspecific inflammatory disease of the intestine including Crohn’s disease (CD) and ulcerative colitis (UC). The drug treatment effect is often limited and accompanied by side effects. A large number of basic and clinical studies have shown that curcumin has the effect of treating IBD and also can maintain the remission of IBD. In this review, the research of curcumin on IBD in recent years is summarized in order to provide reference for further research and application of curcumin.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 99:154006. [PMID: 35299029 DOI: 10.1016/j.phymed.2022.154006] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 02/06/2022] [Accepted: 02/16/2022] [Indexed: 05/11/2023]
Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by high levels of proinflammatory cytokines and epithelial barrier dysfunction. The root of Ligularia fischeri (Ledeb.) Turcz. is a traditional Chinese medicinal herb with diverse therapeutic properties, which has been successfully used to treat inflammation-related diseases. However, little is known about its effect and mechanism against UC. PURPOSE To investigate the efficacy and mechanism of L. fischeri root extracts against UC. METHODS L. fischeri root samples were prepared using the alcohol extraction method and liquid-liquid extraction method. A dextran sodium sulfate-induced UC mouse model and a lipopolysaccharide (LPS)-induced inflammatory cell model were employed in the present study. Cell apoptosis was detected by TUNEL staining, and an enzyme-linked immunosorbent assay was used to quantify the abundance of inflammatory factors in tissues. Hematoxylin and eosin staining and Masson staining were employed to analyze drug toxicity to the liver and kidney. A myeloperoxidase (MPO) assay kit was used to detect neutrophil infiltration in colon tissues. RT-qPCR was then employed to quantify the transcriptional levels of proinflammatory and apoptotic-related genes, while tight junction and apoptosis-related proteins were quantified via western blotting. Gas Chromatography/Mass Spectrometry analysis was then performed to identify the natural compounds in L. fischeri root extracts. RESULTS The water decoction extract, methanol extract, and especially the chloroform extract (CE) exerted potent therapeutic effects in UC mice. Similar to the positive control group (5-aminosalicylic acid), oral administration of CE (30, 60, and 90 mg/kg/d) elicited distinct therapeutic effects on UC mice in the medium- and high-dose groups. CE decreased disease activity index, histopathological score, and MPO level significantly, and effectively retained the colon length. Furthermore, CE significantly reduced the levels of proinflammatory cytokines, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α and enhanced the expression of tight junction proteins, such as zonula occludens (ZO)-1, ZO-2, claudin-1, and occludin, as well as the transcriptional levels of mucins, such as MUC-1 and MUC-2, in UC mice. Notably, CE prevented apoptosis of colonic epithelial cells by up-regulating Bcl-2 and down-regulating Bax. Also, CE inhibited the secretion of pro-inflammatory cytokines and apoptosis in LPS-induced RAW264.7 macrophages via the activation of Bcl-2/Bax signals. CONCLUSIONS Collectively, L. fischeri root extracts, especially CE, have obvious therapeutic effects against UC. CE reduces inflammation and protects the intestinal epithelial cells and intestinal epithelial barrier via activation of the Bcl-2/Bax signaling pathway, and may be a promising therapeutic agent for UC treatment.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) with rising prevalence in developing countries, and limited success of current therapies, natural products have immense potential for therapy due to their "disease modifying and side-effect neutralizing" potential. Myrica salicifolia is traditionally used for gastrointestinal diseases and have reported antiinflammatory activities, but its use in IBD has not yet been studied. Therefore, in the present study, the effects of the root extract of M. salicifolia (Ms.Cr) were investigated using the acetic acid-induced UC model in rats. For 6 days, the rats were given either vehicle (10 mL/kg), lower (200 mg/kg), and higher (400 mg/kg) doses of Ms.Cr, or the positive control drug (prednisolone; 2 mg/kg) orally. A single dosage of 5% acetic acid (1.0 mL) was administered intrarectally to rats on day 6 to induce UC. Disease activity index (DAI), histological observations, the biochemical parameters related to oxidative stress, and specific cytokines such as interleukin-6 (IL-6) and the tumor necrosis factor-α (TNF-α) were determined to assess the effect of Ms.Cr. In comparison to the AA-induced colitis rats, Ms.Cr's pretreatment significantly decreased DAI, colonic ulceration, and inflammatory score. Total glutathione levels and catalase activity were considerably recovered in the colitis group treated with Ms.Cr, whereas enhanced lipid peroxidation in colon tissues was significantly decreased. Moreover, Ms.Cr pretreatment also caused inhibition of the activation of IL-6 and TNF-α in the colonic tissues of respective groups. Based on these findings, Ms.Cr might be developed to treat UC in the future.

Abstract
Gastrointestinal disease is the most common health concern that occurs due to environmental, infectious, immunological, psychological, and genetic stress. Among them, the most frequent diseases are gastric ulcer (GU) and ulcerative colitis (UC). DSS-induced UC and ethanol-stimulated GU models resemble the pathophysiology of human gastrointestinal disease. The current study was designed to explore the anti-oxidation, anti-inflammation, anti-cell death properties of terazosin, an α-adrenergic receptor antagonist, in vivo and in vitro. Our results indicate that terazosin dramatically activates Pgk1, and upregulates glycose metabolism, evidenced by the enhanced ATP production and higher LDH enzymatic activity. Also, terazosin significantly enhances p-AKT expression and inhibits NF-κB p65 activation through abrogating the phosphorylation of IKBα, as well as lowers Caspase-1 and GSDMD expression. The findings in this study demonstrate that terazosin exhibits anti-inflammatory effects by downregulating NF-κB-GSDMD signal pathway, along with enhancing glycolysis for gastrointestinal disease treatment. Meanwhile, we also find terazosin ameliorates ethanol-induced gastric mucosal damage in mice. Collectively, as a clinical drug, terazosin should be translated into therapeutics for gastrointestinal disease soon.

Abstract
Purple sweet potato anthocyanins have been acknowledged for their beneficial effects on human inflammatory bowel diseases (IBD). Although the ability of anthocyanins in modulating the gut microbiota has been reported, the relationship between the bacteria modulated by anthocyanins and intestinal inflammation has not been fully elucidated. We aimed to ascertain whether the purple sweet potato anthocyanin extract (PSPAE) modulation of gut microbiota in the dextran sodium sulphate (DSS) induced chronic colitis mouse model could result in the maintenance of intestinal homeostasis and protection against bacterial intestinal inflammation. Chronic colitis was induced by adding DSS in drinking water while administering the mice with PSPAE via gavage (20 mg kg-1). Effects on colon tissue damage, gut microbiota composition, tight junction protein, and cytokines were evaluated. PSPAE prevented the loss of Bifidobacterium and Lactobacillus and inhibited the increase of Gammaproteobacteria and Helicobacter upon DSS treatment. The non-pathogenic-dependent and pathogenic-dependent microenvironments were established upon treatment with broad-spectrum antibiotics. Both PSPAE treatment and non-pathogenic treatments modified the colonic expression of mouse tight junction proteins and maintained the architecture of the colon. However, the non-pathogenic treatment could not attenuate intestinal inflammation. Moreover, the pathogenic-dependent dysbiosis was exacerbated because of the increasing colonization of pathogens such as Helicobacter. The PSPAE exerted the modulation of gut microbiota to maintain the gut microbiome homeostasis in DSS-induced chronic colitis mice, which may help to propose a new treatment that combines efficacy and reduction of the possibility of bacterial intestinal infection.

Curcumin Improves Epithelial Barrier Integrity of Caco-2 Monolayers by Inhibiting Endoplasmic Reticulum Stress and Subsequent Apoptosis. Gastroenterol Res Pract 2021; 2021:5570796.

Abstract
Curcumin is a natural polyphenol and is supposed to possess antioxidant, anti-inflammatory, anticancer, and antiapoptotic properties. Although some studies have reported the therapeutic effects of curcumin on ulcerative colitis (UC), the specific mechanism remains unclear. An in vitro coculture model of Caco-2 and differentiated THP-1 cells was established. After administration of curcumin (10 μM), Western blot analysis was performed to evaluate the protein levels of tight junction (TJ) proteins zonula occludens- (ZO-) 1 and claudin-1. Annexin V-APC/7-AAD assays and flow cytometry were conducted to assess Caco-2 cell apoptosis. The expression levels of oxidative stress and endoplasmic reticulum stress- (ERS-) related molecules were determined by Western blot analysis. Curcumin administration significantly upregulated ZO-1 and claudin-1 protein levels and reduced Caco-2 cell apoptosis. The protein levels of oxidative stress markers inducible nitric oxide synthase (iNOS) and γH2AX and ERS-induced apoptosis-related molecules C/EBP homologous protein (CHOP) and cleaved caspase-12 were significantly downregulated upon curcumin treatment. Furthermore, curcumin administration greatly blocked the protein kinase-like endoplasmic reticulum kinase- (PERK-) eukaryotic translation initiation factor 2α- (eIF2α-) activating transcription factor 4- (ATF4-) CHOP signaling pathway. Curcumin enhanced intestinal epithelial barrier integrity in the in vitro coculture model by upregulating TJ protein expressions and reducing intestinal epithelial cell apoptosis. The potential mechanisms may be suppression of ERS and subsequent apoptosis.

Abstract
An oral nanoparticle (NPs) encapsulated in chitosan/alginate hydrogel (CA-Gel) with dual-sensitive in pH and reactive oxygen species (ROS) was developed to load curcumin (CUR) based on the intracellular-specific characteristics of macrophages. Chondroitin sulfate (CS) wrapped PBAE-SA-PAPE with intracellular pH/ROS dual-sensitive characteristics and CUR via a simple nanoprecipitation method to form NPs (CS-CUR-NPs), and mixed CA-Gel to acquire the final preparation (CS-CUR-NPs-Gel). CS-CUR-NPs displayed an ideal average particle size (179.19±5.61nm) and high encapsulating efficiency (94.74±1.15%). CS showed a good targeting ability on macrophages and the CA-Gel contribution in protecting NPs from being destroyed in the upper gastrointestinal tract. As expected, CS-CUR-NPs-Gel could significantly alleviate inflammation in DSS-induced UC mice via TLR4-MAPK/NF-κB pathway. This study is the first to attempt to design a novel pH/ROS dual-stimulated release strategy in helping intracellular CUR delivery and anticipated for efficient anti-UC therapy.

Abstract
BACKGROUND Pistacia lentiscus L. (PL) is a flowering plant traditionally used in the treatment of gastrointestinal disorders. The extracts of this plant are endowed with strong pharmacological activities. The aim of our current study was to investigate the anti-inflammatory and potential therapeutic effects of PL leaves aqueous extract (PLAE) against Dextran Sulfate Sodium (DSS)-induced acute colitis. MATERIALS AND METHODS The therapeutic effect of PLAE was evaluated after orally administration of 3% DSS alone or concomitantly with PLAE (50, 100 or 200 mg/Kg). Mucosal lesions were assessed by macroscopic and histopathological examination. In this context, hemorrhage, diarrhea, weight loss, and disease activity index (DAI) were determined daily throughout the experiment. In the same way, hematoxylin-eosin and Alcian blue staining of colonic mucosal were used to evaluate, respectively, mucosal damages and mucus production. Furthermore, the levels of nitric oxide (NO), and pro-inflammatory cytokines [tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] were measured in plasma, as well as in colonic explants and peritoneal macrophages cultures supernatants. RESULTS Administration of DSS + PLAE indicated a significant reduction in clinical score of acute colitis DAI compared to DSS alone administration. Interestingly, histological analysis of the mucosa showed that DSS + PLAE-treated groups exhibited almost normal histology evidenced by an intact epithelium structure and less inflammatory cell infiltration in the mucosa. Alcian bleu staining revealed that DSS + PLAE-treated groups displayed almost normal mucus production. Importantly, a significant decrease in pro-inflammatory mediators (NO, IL-6 and TNF-α) levels in dose-dependent manner was reported in plasma, and culture supernatants of colonic explants and peritoneal macrophages from DSS + PLAE-treated mice compared to the DSS group. CONCLUSION Our results showed that the systemic and local anti-inflammatory activities of aqueous leaves extract of PL improve the clinical signs of acute colitis. Our data suggest that PLAE has beneficial effects and could constitute a promising approach against acute ulcerative colitis by targeting the deregulated immune response.

Abstract
Redox stress is a common feature of gut disorders such as colonic inflammation (inflammatory bowel disease or IBD) and colorectal cancer (CRC). This leads to increased colonic formation of lipid-derived electrophiles (LDEs) such as 4-hydroxynonenal (4-HNE), malondialdehyde (MDA), trans, trans-2,4-decadienal (tt-DDE), and epoxyketooctadecenoic acid (EKODE). Recent research by us and others support that treatment with LDEs increases the severity of colitis and exacerbates the development of colon tumorigenesis in vitro and in vivo, supporting a critical role of these compounds in the pathogenesis of IBD and CRC. In this review, we will discuss the effects and mechanisms of LDEs on development of IBD and CRC and lifestyle factors, which could potentially affect tissue levels of LDEs to regulate IBD and CRC development.

Abstract
Curcumin liposomes (CUR-LPs) was identified by evaluating morphology, appearance, zeta potential, particle diameter, and drug encapsulation efficiency. The results indicated that particle diameter, surface charge and polydispersity index (PDI) of curcumin (CUR)-loaded anionic liposomes were 167 nm, -34 mV and 0.09, respectively. CUR-LPs is high stable pseudo-pH-sensitive nanoparticles system which has a favorable stability in simulated gastric fluid and slower degradation rate allowing CUR sustained release for prolonged times in simulated intestinal fluid. Within 1 h, the CUR consumption was 21.82% in simulated gastric fluid (SGF) and 27.32% in simulated intestinal fluid (SIF), respectively. CUR-LPs could attenuate clinical symptoms including weight loss, diarrhea and fecal bleeding. Especially, it could also prevent dextran sulfate sodium salt (DSS)-inducedcolon tissue damage and colon shortening, and reduce the production of malondialdehyde (MDA), colonic myeloperoxidase (MPO), Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in animal model. Our study illustrated that liposomes (LPs) was a potential carrier to develop the colon-specific drug delivery system incorporating CUR for treating ulcerative colitis.

Abstract
Curcumin has a therapeutic effect on ulcerative colitis, but the underlying mechanism has yet to be elucidated. The aim of the present study was to clarify the possible mechanisms. Dextran sulfate sodium-induced colitis mice were treated with curcumin via gavage for 7 days. The effects of curcumin on disease activity index (DAI) and pathological changes of colonic tissue in mice were determined. Interleukin (IL)-6, IL-10, IL-17 and IL-23 expression levels were measured by ELISA. Flow cytometry was used to detect the ratio of mouse spleen regulatory T cells (Treg)/Th17 cells, and western blotting was used to measure the nuclear protein hypoxia inducible factor (HIF)-1α level. The results demonstrated that curcumin can significantly reduce DAI and spleen index scores and improve mucosal inflammation. Curcumin could also regulate the re-equilibration of Treg/Th17. IL-10 level in the colon was significantly increased, while inflammatory cytokines IL-6, IL-17 and IL-23 were significantly reduced following curcumin treatment. No significant difference in HIF-1α was observed between the colitis and the curcumin group. It was concluded that oral administration of curcumin can effectively treat experimental colitis by regulating the re-equilibration of Treg/Th17 and that the regulatory mechanism may be closely related to the IL-23/Th17 pathway. The results of the present study provided molecular insight into the mechanism by which curcumin treats ulcerative colitis.

Abstract
The goal of this work was to assess the usability of yeast glucan particles (GPs) as carriers for curcumin and determine the beneficial effect of a pharmacological composite of curcumin in GPs on dextran sulfate sodium induced colitis in rats. The assessment of the anti-inflammatory effect of particular substances was evaluated on the basis of the calculated disease activity index and by assessment of cytokines and enzymes from the gut tissue - tumor necrosis factor α (TNF-α), transforming growth factor β1, interleukin (IL)-1β, IL-6, IL-10, IL-17, catalase, superoxide dismutase 2, myeloperoxidase (MPO), and matrix metalloproteinase 9. Composites of GPs with incorporated curcumin showed promising results with the capability to lower symptoms of colitis and significantly decrease the production of pro-inflammatory cytokines TNF-α, IL-1β, IL-6, and the activity of MPO, as well. The anti-inflammatory effect of the composites was greater than those of pure GPs or curcumin.

Ascorbyl-dipalmitate-stabilised nanoemulsions as a potential localised treatment of inflammatory bowel diseases. Int J Pharm 2020; 586:119533.

Abstract
Current efforts on inflammatory bowel diseases (IBD) treatment are focused on strategies for localised drug delivery at the intestinal mucosa. Despite the potential of curcumin (CC) for IBD treatment, its low solubility and stability limit its application. Thus, the design of nanocarriers that focus CC delivery at the intestinal epithelium is an area of interest. This work proposes α-tocopherol nanoemulsions (NE) stabilised by ascorbyl-2,6-dipalmitate (ADP) as intestinal CC-carriers. The antioxidant capacity of α-tocopherol and ADP could have a synergistic effect on IBD-affected tissues, characterised by an oxidative environment. We obtained nanoemulsions (NE-ADP) with size below 200 nm, negative surface charge, stable in gastrointestinal media and no toxic in the Caco-2 cell model. Intracellular retention of NE-ADP in Caco-2 cells was observed by confocal microscopy. The extremely low Papp values obtained for CC and α-tocopherol indicated the lack of transport across the Caco-2 monolayer. Control nanoemulsion stabilised by lecithin (NE-L) was greatly transported across the Caco-2 cells monolayer, confirming the relevance of ADP on the cellular retention of NE-ADP. The therapeutic potential of NE-ADP was shown by the significant decrease of intracellular ROS levels. Altogether, these results indicate the potential of NE-ADP as a novel approach for the treatment of IBD.

Abstract
The increasing role of copper oxide nanoparticles (CuO NPs) in many industries and their broad range of applications increase its potential toxic effects. Curcumin possesses a wide range of health benefits. This study aimed to evaluate the role of curcumin in attenuating CuO NPs toxicity in rat kidney. Thirty six animals were divided into five groups; control groups (I, II), curcumin group orally received curcumin 200 mg/kg bw, CuO NPs group orally gavaged 250 mg/kg bw CuO NPs and combined group orally gavaged curcumin and CuO NPs. Treatment was given for 3 months. Administration of CuO NPs revealed elevation in serum creatinine and blood urea nitrogen levels, elevated kidney and urine levels of kidney injury molecule-1, decreased catalase, superoxide dismutase activities, total sulfhydryl, reduced glutathione content, increased serum reactive oxygen species, tissue total oxidant status, lipid hydroperoxides, protein carbonyl, malondialdehyde, nitric oxide levels, increased interleukin-1β, tumor necrosis factor-α, nuclear factor (NF-κB), and decreased heme oxygenase-1 (HO-1) and γ-glutamylcysteine synthetase (γ-GCS) genes expression. Moreover, histopathological alteration in kidney structure was detected. Immunohistochemical-stained sections by caspase-3 reaction revealed apoptosis. Pretreatment with curcumin improved most of the adverse effects in rats treated with CuO NPs regarding oxidative stress and inflammatory indices in kidney, and kept histopathological- and immunohistochemical-stained sections near to normal. This study shows that curcumin administration attenuates the toxicity in the kidney of CuO NPs-treated rats through its antioxidant, anti-inflammatory, and antiapoptotic effects.

Abstract
This study investigated the effects of L-theanine supplementation on the colonic mucosa injury in C57BL/6J male mice treated with dextran sulfate sodium (DSS)-induced colitis. Treatment with L-theanine significantly decreased the disease activity index and ameliorated the inflammation-associated pathological damage in colon length, as well as the histopathological features of DSS-induced colitis. L-Theanine administration also inhibited DSS-induced changes in the colonic tissue that included myeloperoxidase by 4.5-fold and malondialdehyde by 2.3-fold in comparison to the DSS group. In addition, GSH was increased by 85% and lipopolysaccharides level was decreased by 55% in comparison to the DSS group. Proinflammatory cytokines expression, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, at the both protein and mRNA levels were also decreased significantly. Notably, the increase in serum content of lipopolysaccharides and colonic expressions of inducible nitric oxide synthase, cyclooxygenase-2, toll like receptor (TLR)-2, TLR-4, TLR-6, and TLR-9 induced by DSS were also significantly inhibited by L-theanine administration. In addition, L-theanine also attenuated the reduction of serum contents of diamine oxidase and the production of short-chain fatty acids in the colonic tissue, and gene expression of mucosal barrier zonula occludens-1 and claudin-1 in DSS-induced colitis. Furthermore, 16S rRNA phylogenetic sequencing revealed a shift in microbial community composition induced by DSS, but no significant difference was observed following L-theanine supplementation. Overall, our findings demonstrated that L-theanine inhibits intestinal inflammation and protects against intestinal barrier disruption in mice with DSS-induced colitis. Further clinical trials should be considered to assess the effects of L-theanine supplementation on oxidative and inflammatory responses in humans.

Abstract
Oxidative stress is recognized as a common pathology that affects up to half of all men infertile. Fucoxanthin possesses antioxidant activity, and several investigators have reported anti-inflammatory action. This study extracted powder of Sargassum glaucescens by acetone to obtained fucoxanthin rich-brown algae extract (FXE). The objective of this study was to evaluate the ameliorative effects of fucoxanthin extract from Sargassum glaucescens on lipopolysaccharide-induced inflammation in RAW264.7 macrophage cells and its protective effects of against Cisplatin (CP)-induced reproductive damage in hamsters. Eighty male Syrian hamsters were injected with and without CP, then daily oral gavage with various concentrations of fucoxanthin for 5 days. Treatment with FXE reduced the level of reactive oxygen species and malondialdehyde in RAW 264.7 cells and the rats' testis as well as protective effects on mitochondrial membrane potential. The FXE administration also improved testosterone level and alpha-glucosidase activity. The sperm count also increased after treated with FXE, whereas sperm abnormality was reduced. Histopathological analysis showed that FXE successfully improved the seminiferous tubules morphology. According to these findings, fucoxanthin extract from Sargassum glaucescens can be used as an alternative for the treatment of testicular damage.

Abstract
In this study, the effects of tyrosol were investigated in DSS-induced experimental ulcerative colitis model. For this purpose, rats were divided into five groups of seven rats in each: control group, colitis group (DSS-4%), tyrosol group (tyrosol 20 mg/kg), sulfasalazine (sulfasalazine+DSS 100 mg/kg), and treatment group (tyrosol+DSS 20 mg/kg). In the study, the active substances were administered to all animals for a period of 21 days. At the end of the study, malondialdehyde (MDA) levels increased (p < 0.001); GSH level (p < 0.05) along with GSH.Px (p < 0.01) and CAT (p < 0.001) activities decreased in the DSS-induced colitis group. However, with the administration of tyrosol, MDA and GSH levels along with GSH.Px and CAT activities came to the same levels as the control group. In the colitis group, an increase occurred in IL-6, COX-2, and NF-κB parameters, which created a significant difference compared to the control group (p < 0.001). Similarly, TNF-α levels also significantly increased with the administration of DSS (p < 0.05) which created a significant difference compared to the control group, while there was no difference among the other groups. As for the Nrf-2 data, it decreased with the administration of DSS which created a significant difference compared to the control group (p < 0.05), while there was no difference in other groups. In the colitis-induced group, IL-6, COX-2, and NF-κB gene expression levels also similarly increased but returned to the normal levels with the administration of tyrosol. In the histopathological scoring, the negativity that increased with the administration of DSS returned to the normal levels with the administration of tyrosol+DSS. In conclusion, according to the data obtained, tyrosol fixed the destruction picture in the DSS-induced colitis model, giving rise to thought that it has a protective effect.

Lu PD, Zhao YH. Targeting NF-κB pathway for treating ulcerative colitis: comprehensive regulatory characteristics of Chinese medicines. Chin Med 2020; 15:15. [PMID: 32063999 PMCID: PMC7011253 DOI: 10.1186/s13020-020-0296-z] [Citation(s) in RCA: 69] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Accepted: 01/30/2020] [Indexed: 12/15/2022] Open
Abstract
Nuclear factor-kappa B (NF-κB) is a kind of multi-functional nuclear transcription factor involved in regulating gene transcription to influence pathological evolution of inflammatory and immune diseases. Numerous literature evidence that NF-κB pathway plays an essential role in pathogenic development of ulcerative colitis (UC). UC is a chronic non-specific inflammatory bowel disease, and until now, therapeutic agents for UC including aminosalicylates, corticosteroids and immune inhibitors still cannot exert satisfied effects on patients. In recent years, Chinese medicines suggest the advantages of alleviating symptoms and signs, decreasing side-effects and recurrence, whose one of mechanisms is related to regulation of NF-κB pathway. In this review, we categorize Chinese medicines according to their traditional therapeutic functions, and summarize the characteristics of Chinese medicines targeting NF-κB pathway in UC treatment. It indicates that 85 kinds of Chinese medicines’ compounds and formulae can directly act on NF-κBp65; while 58 Chinese medicines’ ingredients and formulae indirectly suppress NF-κBp65 by regulation of its upstream or other related pathways. Moreover, by the analysis of Chinese medicines’ category based on their traditional functions, we conclude the category of dampness-drying and detoxificating medicine targeting NF-κB pathway accounts for primary status for amelioration of UC. Simultaneously, this review also contributes to the choices of Chinese medicine category and provides curative potential of Chinese medicines for clinical UC treatment.

Phytochemical drug candidates for the modulation of peroxisome proliferator-activated receptor γ in inflammatory bowel diseases. Phytother Res 2020; 34:1530-1549. [PMID: 32009281 DOI: 10.1002/ptr.6625] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 12/23/2019] [Accepted: 01/14/2020] [Indexed: 12/12/2022]
Abstract
Plant-based compounds or phytochemicals such as alkaloids, glycosides, flavonoids, volatile oils, tannins, resins, and polyphenols have been used extensively in traditional medicine for centuries and more recently in Western alternative medicine. Extensive evidence suggests that consumption of dietary polyphenolic compounds lowers the risk of inflammatory diseases. The anti-inflammatory properties of several phytochemicals are mediated through ligand-inducible peroxisome proliferator-activated receptors (PPARs), particularly the PPARγ transcription factor. Inflammatory bowel disease (IBD) is represented by ulcerative colitis, which occurs in the mucosa of the colon and rectum, and Crohn's disease (CD) that can involve any segment of gastrointestinal tract. Because of the lack of cost-effective pharmaceutical treatment options, many IBD patients seek and use alternative and unconventional therapies to alleviate their symptoms. PPARγ plays a role in the inhibition of inflammatory cytokine expression and activation of anti-inflammatory immune cells. The phytochemicals reported here are ligands that activate PPARγ, which in turn modulates inflammatory responses. PPARγ is highly expressed in the gut making it a potential therapeutic target for IBDs. This review summarizes the effects of the currently published phytochemicals that modulate the PPARγ pathway and reduce or eliminate colonic inflammation.

Abstract
Radiation-induced enteritis is one of the greatest challenges in radiotherapy. The current study was designed to evaluate the ameliorative effect of resveratrol, which exhibits anti-inflammatory property, against radiation-induced intestinal injury in rats and to explore the underlying mechanism. Rats were exposed to a single dose of 5 Gy. Resveratrol (20 mg/kg/day) was orally administered to irradiated rats over 3 weeks. Results showed that resveratrol ameliorated the intestinal oxidative stress parameters; malondialdehyde (MDA) content, glutathione (GSH) level, and catalase (CAT) activity compared to irradiated group. Furthermore, resveratrol reduced the contents of inflammatory cytokines; tumor necrosis factor α (TNF-α), nuclear factor-kappa (NF-κB), and interleukin 1β (IL-1β) in intestine. Western blotting analysis revealed that resveratrol down-regulated the proteins expression of phosphoinositide 3-kinases (PI3K), protein kinase B (Akt) as well as the mammalian target of rapamycin (mTOR) in intestinal tissues of irradiated rats and thus reduced the inflammatory mediator production. These results were confirmed by histopathological investigation. In conclusion, resveratrol attenuated intestinal inflammation following irradiation via modulating PI3K/Akt/mTOR pathway and thereby could be a promising adjuvant in radiotherapy.

Abstract
The incidence of ulcerative colitis (UC) is increasing worldwide, and it has become a growing problem in Asia. Previous research on UC has focused on serum, plasma, urine, gut tissues, and fecal metabolic profiling, but a comprehensive investigation into the correlation between the severity of colitis and changes in liver metabolism is still lacking. Since the liver and gut exchange nutrients and metabolites through a complex network, intestinal diseases can affect both the liver and other organs. In the present study, concentration-dependent dextran sodium sulfate (DSS)-induced ulcerative colitis was employed to examine changes in liver metabolism using a proton nuclear magnetic resonance spectroscopy (1H-NMR)-and ultra-performance liquid chromatography time of flight mass spectroscopy (UPLC-TOF MS)-based metabolomics study. Using the multivariate statistical analysis method orthogonal projections to latent structures discriminant analysis (OPLS-DA), changes in metabolites depending on the DSS dose could be clearly distinguished. Specifically, hepatic metabolites involved in one-carbon metabolism, carnitine-related metabolism, and nucleotide synthesis were found to be affected by intestinal inflammation, implying the existence of a metabolic connection between the gut and liver. We are currently investigating the significance of this metabolic condition in UC.

Abstract
BACKGROUND AND AIMS Curcumin has anti-inflammatory properties. The aim of this study was to evaluate the effect of curcumin on improvement of the disease activity in ulcerative colitis (UC). METHODS In this randomized double-blind clinical trial, 70 patients with mild-to-moderate UC were randomly assigned to curcumin (1,500 mg/day) or placebo intake for 8 weeks. Disease clinical activity, quality of life, serum levels of tumor necrosis factor alpha (TNF-α), high-sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR) values, and complete blood count were measured. RESULTS Changes in Simple Clinical Colitis Activity Index score were significantly higher in the curcumin than the placebo group (-5.9 ± 2.08 vs. -2.1 ± 2.6; p = .001). The scores of Inflammatory Bowel Disease Questionnaire-9 and quality of life were significantly higher in the intervention group compared to the control group (p = .006). Furthermore, the curcumin supplementation reduced the serum hs-CRP concentration (-6.3 ± 13.6 vs. 3.7 ± 11.6 μg/ml; p = .01) and ESR levels significantly (-1.6 ± 2.7 vs. -0.09 ± 2.4 mm/hr; p = .02) in comparison with the control group. No significant changes were observed in the TNF-α levels of both groups. CONCLUSIONS Consumption of the curcumin supplement, along with drug therapy, is associated with significant improvement of the clinical outcomes, quality of life, hs-CRP, and ESR in patients with mild-to-moderate UC.

Abstract
BACKGROUND Tumor necrosis factor-alpha (TNF-alpha), among cytokines that mediate the inflammatory process, plays an important role in diseases involving the loss of intestinal barrier integrity. Several molecules with anti-TNF-alpha activity have been studied aiming to develop new therapies. The purpose of this paper is to describe the systematic review protocol of experimental studies that determine mechanisms of action of molecules with anti-TNF-alpha activity on intestinal barrier inflammation. METHODS This protocol is guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes Protocols (PRISMA-P). The databases to be searched are PubMed, EMBASE, Scopus, ScienceDirect, and Web of Science. Experimental studies in rats or mice that assessed the activity of anti-TNF-alpha molecules in models of intestinal barrier inflammation will be included in the systematic review. Studies characteristics, experimental model, and main results will be described and the bias risk assessment will be performed. Two independent reviewers will perform study selection, data extraction, and methodological quality assessment. A narrative synthesis will be made for the included studies. Also, if sufficient data is available, a meta-analysis will be conducted. I statistics will be used to assess heterogeneity. RESULTS The present protocol will assist in producing a systematic review that identifies the mechanisms underlying the reduction of TNF-alpha in intestinal barrier inflammation models. CONCLUSION The systematic review may contribute to the theoretical basis of research on new molecules with anti-TNF-alpha potential and, consequently, in the development of new therapies employed in humans.

Abstract
BACKGROUND Ulcerative Colitis (UC) is characterized by chronic inflammation of the mucosal layers of the colon. Treatment of refractory UC is challenging and has a huge healthcare burden. Although there have been advancements in immunomodulatory therapies, these require a step-up financially, and these medications are also associated with significant adverse events. Curcumin, an active ingredient of turmeric, has been studied in the past and found to be useful in the treatment of UC when used as an adjuvant along with mesalamine. We did a systematic review and meta-analysis to explore the role curcumin plays in clinical and endoscopic remission in patients with UC. MATERIALS AND METHODS A comprehensive literature review was conducted by first searching the MEDLINE, Pubmed, and Embase databases through December 2017 to identify all studies that compared the use of curcumin when used along with mesalamine with placebo for clinical and endoscopic improvement and remission. RESULTS Three randomized controlled trials including 142 patients were included in the study. Use of curcumin along with mesalamine was associated with increased odds of clinical remission (pooled odds ratio of 6.78, 95% CI: 2.39-19.23, P = 0.042). Clinical improvement, endoscopic remission and improvement rate also trended higher in the curcumin group compared to placebo. CONCLUSIONS This study demonstrates higher clinical remission rates when curcumin was used in combination with mesalamine to achieve remission in patients with UC. Curcumin, due to its cost effectiveness and safer side effect profile, can decrease the healthcare burden and morbidity associated with this relapsing and remitting disease.

Protective effect of curcumin against irinotecan‑induced intestinal mucosal injury via attenuation of NF‑κB activation, oxidative stress and endoplasmic reticulum stress. Int J Oncol 2019; 54:1376-1386. [PMID: 30968152 DOI: 10.3892/ijo.2019.4714] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2018] [Accepted: 12/06/2018] [Indexed: 11/05/2022] Open
Abstract
Irinotecan (CPT‑11) is a DNA topoisomerase I inhibitor which is widely used in clinical chemotherapy, particularly for colorectal cancer treatment. However, late‑onset diarrhea is one of the severe side‑effects of this drug and this restricts its clinical application. The present study aimed to investigate the protective effects of curcumin treatment on CPT‑11‑induced intestinal mucosal injury both in vitro and in vivo and to elucidate the related mechanisms involved in these effects. For this purpose, mice were intraperitoneally injected with CPT‑11 (75 mg/kg) for 4 days to establish a model of late‑onset diarrhea. Curcumin (100 mg/kg) was intragastrically administered 8 days before the injection of CPT‑11. Injury to small intestinal tissues was examined by H&E staining. The protein expression of prolyl 4‑hydroxylase subunit beta (P4HB) and peroxiredoxin 4 (PRDX4) was detected by immunohistochemistry, as well as western blot analysis. IEC‑6 cell viability was detected by MTT assay. Flow cytometry was performed to examine the cell apoptotic rate, mitochondrial membrane potential and reactive oxygen species (ROS) generation. Immunofluorescence was used to observe the localization of nuclear factor (NF)‑κB. The levels of cleaved caspase‑3, glucose‑regulated protein, 78 kDa (GRP78), P4HB, PRDX4 and CHOP were detected by western blot analysis. The results revealed that in vivo, curcumin effectively attenuated the symptoms of diarrhea and abnormal intestinal mucosa structure induced by CPT‑11 in nude mice. Treatment with curcumin also increased the expression of P4HB and PRDX4 in the tissue of the small intestine. In vitro, curcumin, exhibited little cytotoxicity when used at concentrations <2.5 µg/ml for 24 h in IEC‑6 cells. At this concentration, curcumin also improved cell morphology, inhibited apoptosis, maintained mitochondrial membrane potential and reduced the elevated levels of ROS induced by CPT‑11 (20 µg/ml). Furthermore, curcumin abolished NF‑κB signal transduction and protected the cells from CPT‑11‑induced apoptosis by upregulating the expression of molecular chaperones, such as GRP78, P4HB and PRDX4, and suppressing the levels of the apoptosis‑related proteins, CHOP and cleaved caspase‑3. On the whole, our data indicate that curcumin exerted protective effects against CPT‑11‑induced intestinal mucosa injury. The protective effects of curcumin are mediated by inhibiting the activation of NF‑κB, and suppressing oxidative stress and endoplasmic reticulum stress.

Abstract
BACKGROUND NLRP3 inflammasome mediates IL-1β maturation, therefore plays a vital role in the development of IBD. Curcumin is known for possessing strong anti-inflammatory property. OBJECTIVE The present study was to investigate the protective effects of curcumin on dextran sulfate sodium (DSS)-induced colitis through inhibiting NLRP3 inflammasome activation and IL-1β production. METHODS LPS-primed macrophages were treated with curcumin prior to DSS triggering NLRP3 inflammasome activation, IL-1β secretion and ASC oligomerization were observed. The mechanisms of curcumin in the inhibition of DSS-induced inflammasome activation were explored. Curcumin or caspase-1/NLRP3 inhibitor was administrated respectively in DSS-induced colitis mouse model. The changes of body weight, disease activity index, colon length were measured. Additionally, mature IL-1β and other inflammatory cytokines, MPO activity and histopathological damage were analyzed for the evaluation of colitis severity. RESULTS NLRP3 inflammasome activation was dramatically inhibited by curcumin in DSS-stimulated macrophages, as evidenced by decreased IL-1β secretion, less caspase-1 activation and ASC specks. Mechanistically, curcumin prevented DSS-induced K+ efflux, intracellular ROS formation and cathepsin B release, three major cellular events mediating NLRP3 inflammasome activation. In DSS-induced colitis, curcumin administration significantly ameliorated colitis symptoms by reducing weight loss, DAI and colon length shortening. Meanwhile, curcumin significantly decreased the expression of multiple inflammatory cytokines (including mature IL-1β, IL-6, MCP-1), MPO activity, caspase-1 activity as well as histopathological damage. Furthermore, blockage of NLRP3 inflammasome activation in vivo with specific NLRP3 inhibitor abrogated the further inhibitory effect of curcumin on DSS-induced colitis. CONCLUSION Curcumin could strongly suppress DSS-induced NLRP3 inflammsome activation and alleviate DSS-induced colitis in mice, thus it may be a promising candidate drug in clinical application for IBD therapy.

Abstract
Inflammatory bowel disease (IBD) is a known medical burden in most developed countries and a significant cause of morbidity. The IBD label includes Crohn's disease (CD) and ulcerative colitis (UC). Pharmacological and surgical intervention are the two main management approaches for IBD. Some drugs have been developed for IBD therapy, but accessibility is limited due to high costs. Furthermore, these agents have demonstrated inactivity over long-term treatment courses. Therefore, an urgent need is present for new treatment options that are safe, able to sustain clinical remission, and improve mucosal gut healing. Seaweed has received much attention in the pharmacological field owing to its various biomedical properties, including the prolongation of blood clotting time, as well as antitumor, anti-inflammation, and antioxidant effects. This study therefore aimed to examine the effects of a dietary polysaccharide-rich extract obtained from Eucheuma cottonii (EC) on a model of colitis. Colitis was induced in male BALB/c mice by the administration of 2.5% (w/v) dextran sulfate sodium (DSS) for 7 days. DSS-induced mice were treated with either one of three different doses of EC extracts (0.35, 0.70, and 1.75 g/kg body weight) or curcumin as a positive control (0.10 g/kg). Mice were sacrificed post-treatment and blood samples were collected. The disease activity index (DAI) and inflammatory cytokine levels (tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-10) were measured. After treatment for 7 days, EC extract administration protected against weight loss and decreased the colon weight per length ratio. EC extract administration also decreased pro-inflammatory cytokine expression, increased IL-10 levels, and reduced colonic damage. Therefore, a dietary polysaccharide-rich extract from E. cottonii reduced DSS-induced bowel inflammation, thereby becoming a promising candidate for the treatment of colitis.

Intestinal anti-inflammatory effect of the probiotic Saccharomyces boulardii in DSS-induced colitis in mice: Impact on microRNAs expression and gut microbiota composition. J Nutr Biochem 2018; 61:129-139. [PMID: 30236870 DOI: 10.1016/j.jnutbio.2018.08.005] [Citation(s) in RCA: 83] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2018] [Revised: 07/19/2018] [Accepted: 08/24/2018] [Indexed: 02/07/2023]
Abstract
The beneficial effects exerted by probiotics in inflammatory bowel disease (IBD) are well known, although their exact mechanisms have not been fully elucidated, and only few studies have focused on their impact on selected miRNAs and the gut microbiota composition. Therefore, our aim was to correlate the intestinal anti-inflammatory activity of the probiotic Saccharomyces boulardii in the dextran sodium sulphate (DSS) model of mouse colitis and the changes induced in miRNA expression and gut microbiota populations. Probiotic was given orally (5×109 CFU) to C57BL/6 mice for 26 days. After 2 weeks, the colitis was induced adding DSS to the drinking water. Mice were scored daily using a Disease Activity Index (DAI). After sacrifice, the colonic specimens were evaluated by determining the expression of inflammatory markers and micro-RNAs by qRT-PCR. Moreover, changes in microbiota populations were evaluated by pyrosequencing. Probiotic ameliorated the colonic damage induced by DSS, as evidenced by lower DAI values and colonic weight/length compared with untreated mice. The treatment modified the colonic expression of different inflammatory markers and the epithelial integrity proteins, and induced changes in micro-RNAs expression. Moreover, microbiota characterization showed that probiotic treatment increased bacterial diversity, thus ameliorating the dysbiosis produced by DSS-colitis. Saccharomyces boulardii exerted intestinal anti-inflammatory effects in DSS-mouse colitis, through the modulation in the immune response, involving modification of altered miRNA expression, being associated to the improvement of the inflammation-associated dysbiosis in the intestinal lumen, which could be of great interest to control the complex pathogenesis of IBD.

Abstract
Ulcerative colitis (UC) is a chronic, relapsing, remitting, and inflammatory disorder that afflicts millions of people around the world. It carries a substantial economic burden, reducing the quality of life, ability to work, and increasing disability. Conventional medical treatment of UC includes the use of aminosalicylates, corticosteroids, and immunosuppressive drugs. However, these medicines are not always effective due to some serious side effects. Nuclear factor-kappa B (NF-κB) is a key factor in the inflammatory setting and strongly affects the course of mucosal inflammation in UC. This review aims to describe the complex role of NF-κB in UC and discuss existing pharmacological attempts by curcumin for blocking NF-κB activation to develop new therapeutic strategies in UC. Several studies have shown intriguing pharmacologic effects associated with curcumin, which inhibits NF-κB expression by regulating NF-κB/IkB pathway and down-regulation expression of pro-inflammatory cytokines, such as Interleukin (IL)-1, IL-6, IL-8, and tumor necrosis factor (TNF)-α. The efficacy of curcumin has been confirmed in several experimental models of UC. Furthermore, curcumin significantly induced clinical remission in active mild-to-moderate UC patients and reduced clinical relapse in quiescent UC patients. The inhibitory effects of curcumin on NF-κB and its unrivaled safety profile indicate that it remains effective for the treatment of UC. In addition, curcumin is a nontoxic, inexpensive, and easily available natural polyphenol. In conclusion, curcumin can be used as a potential and safe drug in the management of patients with remission and mild-to-moderate UC.

Abstract
The beneficial effects of probiotics on immune-based pathologies such as inflammatory bowel disease (IBD) have been well reported. However, their exact mechanisms have not been fully elucidated. Few studies have focused on the impact of probiotics on the composition of the colonic microbiota. The aim of the present study was to correlate the intestinal anti-inflammatory activity of the probiotic Escherichia coli Nissle 1917 (EcN) in the dextran sodium sulfate (DSS) model of mouse colitis with the changes induced in colonic microbiota populations. EcN prevented the DSS-induced colonic damage, as evidenced by lower disease activity index (DAI) values and colonic weight/length ratio, when compared with untreated control mice. The beneficial effects were confirmed biochemically, since the probiotic treatment improved the colonic expression of different cytokines and proteins involved in epithelial integrity. In addition, it restored the expression of different micro-RNAs (miR-143, miR-150, miR-155, miR-223, and miR-375) involved in the inflammatory response that occurs in colitic mice. Finally, the characterization of the colonic microbiota by pyrosequencing showed that the probiotic administration was able to counteract the dysbiosis associated with the intestinal inflammatory process. This effect was evidenced by an increase in bacterial diversity in comparison with untreated colitic mice. The intestinal anti-inflammatory effects of the probiotic EcN were associated with an amelioration of the altered gut microbiome in mouse experimental colitis, especially when considering bacterial diversity, which is reduced in these intestinal conditions. Moreover, this probiotic has shown an ability to modulate expression levels of miRNAs and different mediators of the immune response involved in gut inflammation. This modulation could also be of great interest to understand the mechanism of action of this probiotic in the treatment of IBD.

Abstract
Background Curcumin has been reported to have anti-inflammatory and anti-nociceptive effects. The present study was designed to explore the potential therapeutic effects of curcumin on visceral hyperalgesia and inflammation in a rat model of ulcerative colitis. We observed the effects of orally administered curcumin on the disease activity index, histological change in colon, colorectal distension-induced abdominal withdrawal reflex, the expression of transient receptor potential vanilloid 1 (TRPV1) and phosphorylated TRPV1 in dextran sulfate sodium-induced colitis rats. In addition, a HEK293 cell line stably expressing human TRPV1 (hTRPV1) was used to examine the effects of curcumin on the change in membrane expression of TRPV1 induced by phorbol myristate acetate (a protein kinase C activator). Results Repeated oral administration of curcumin inhibited the increase in abdominal withdrawal reflex score induced by dextran sulfate sodium without affecting dextran sulfate sodium-induced histological change of colon and the disease activity index. A significant increase in colonic expression of TRPV1 and pTRPV1 was observed in dextran sulfate sodium-treated rats and this was reversed by oral administration of curcumin. TRPV1 expression in L6-S1 dorsal root ganglion was increased in the small- to medium-sized isolectin B4-positive non-peptidergic and calcitonin gene-related peptide-positive peptidergic neurons in dextran sulfate sodium-treated rats and oral administration of curcumin mitigated such changes. In the HEK293 cell line stably expressing hTRPV1, curcumin (1, 3 µm) inhibited phorbol myristate acetate-induced upregulation of membrane TRPV1. Conclusion Oral administration of curcumin alleviates visceral hyperalgesia in dextran sulfate sodium-induced colitis rats. The anti-hyperalgesic effect is partially through downregulating the colonic expression and phosphorylation of TRPV1 on the afferent fibers projected from peptidergic and non-peptidergic nociceptive neurons of dorsal root ganglion.

Abstract
Colitis is a chronic inflammation and ulcer on the inner lining of the large intestine. For many centuries Ocimum gratissimum (OG) leaves have been used in folk medicine in Nigeria to treat inflammatory bowel diseases, however, to date, the anti-colitis effects of OG have not been scientifically proven. In this study we investigated the effects of polyphenol rich extract of Ocimum gratissimum (PREOG) leaf on colonic mucosa injury in colitis, its mechanisms, initial administration time and dosage. Dextran sodium sulfate (DSS)-induced rat colitis models was used. PREOG administration was initiated at 3 and 7 d after the model was established at doses of 200, 400 and 800 mg/kg for 7 d. 5-aminosalicylic acid (5-ASA) was used as a reference drug. The disease activity index (DAI), vascular permeability, markers of oxidative stress, granulocyte infiltration, inflammation and histopathological alteration were evaluated. Obvious colonic inflammation and mucosa injuries were observed in DSS-induced colitis groups. PREOG administration promoted repair of colonic mucosa injuries, attenuated inflammation, and decreased DAI scores in rats with colitis. PREOG also decreased the plasma concentrations of Interleukin-(IL)-6 and tumor necrosis factor (TNF)-α, and concentrations of myeloperoxidase, nitric oxide, cyclooxygenase-2 and malondialdehyde in the colon, and increased the plasma concentrations of IL-4 and IL-10 as well as the concentration of superoxide dismutase, catalase and reduced glutathione in the colon. The efficacy of PREOG was dosage dependent. In conclusion, OG repairs colonic mucosa injury in experimental colitis through its ant-inflammatory and ant-oxidant. Its efficacy related to initial administration time and dose.

Abstract
Background Curcumin, a yellow ingredient of turmeric (Curcuma longa Linn, Zingiberaceae), has long been used in traditional folk medicine in the management of inflammatory disorders. Although curcumin has been reported to inhibit experimentally-induced colitis and carcinogenesis, the underlying molecular mechanisms remain largely unresolved. Methods Murine colitis was induced by dextran sulfate sodium (DSS) which mimics inflammatory bowel disease. Curcumin or tetrahydrocurcumin was given orally (0.1 or 0.25 mmol/kg body weight daily) for 7 days before and together with DSS administration (3% in tap water). Collected colon tissue was used for histologic and biochemical analyses. Results Administration of curcumin significantly attenuated the severity of DSS-induced colitis and the activation of NF-κB and STAT3 as well as expression of COX-2 and inducible nitric oxide synthase. In contrast to curcumin, its non-electrophilic analogue, tetrahydrocurcumin has much weaker inhibitory effects. Conclusions Intragastric administration of curcumin inhibited the experimentally induced murine colitis, which was associated with inhibition of pro-inflammatory signaling mediated by NF-κB and STAT3.

Abstract
BACKGROUND Roflumilast (Rof), a phosphodiesterase 4 (PDE4) inhibitor, has been shown to be an effective agent in inflammatory diseases and marketed for chronic obstructive pulmonary disease. OBJECTIVE This study was conducted to examine the potential anti-inflammatory effects of Rof in dextran sulphate sodium (DSS)-induced ulcerative colitis (UC) in rats and to investigate the molecular mechanisms underlying these effects. METHODS Forty male Wistar rats were divided into four groups: normal control, colitis group (rats received 5% DSS in their drinking water continuously for 7 days), Rof group, and sulfasalazine (SLZ) group. The Rof (5 mg/kg) and SLZ (500 mg/kg) groups underwent pretreatment with DSS one week ahead of DSS challenge and parallel with DSS. Colitis was determined by assessing colon length, weight loss, histologic colon score, quantifying the concentration of tumor necrosis factor alpha (TNF-α), nitric oxide (NO), cyclic adenosine monophosphate (cAMP), myeloperoxidase (MPO) activity and inducible nitric oxide synthase (iNOS) gene expression in colon tissue. RESULTS Rof attenuated the severity of colitis as evidenced by increased colon length, prevention of body weight loss, and improved colon histologic score compared to DSS group. Rof also suppressed the inflammatory response induced in DSS colitis group by decreasing colon concentration of TNF-α, NO and MPO activity and down- regulation of iNOS gene expression. The level of cAMP was increased by Rof compared to DSS group. The obtained results of Rof were comparable to those exerted by SLZ. CONCLUSION These findings revealed the beneficial effects of Rof in alleviating inflammation in DSS colitis.

Abstract
BACKGROUND Dextran sulfate sodium (DSS)-induced colitis is the most widely used model that resembles ulcerative colitis (UC) in human with challenging chronic mechanistic oxidative stress-inflammatory/immunological cascades. In models of acute colitis, reduction of oxidative stress and inflammatory burdens beside manipulation of many transcriptional factors were achieved by metformin or alpha-lipoic acid (α-LA). Currently, in vivo DSS-induced chronic colitis was conducted and the possible therapeutic roles of metformin and/or α-LA were explored. METHODS Chronic UC was induced by adding 5% DSS orally in drinking water for 7days followed by 3% DSS in drinking water for 14days in adult male albino Wistar rats. Intraperitoneal administration of α-LA (25mg/kg, twice/day) and/or metformin (100mg/kg/day) were set at day 7 of DSS administration and continued for 14days. Body weights, survival rates, disease activity index (DAI), colonic oxidative stress markers, tumor necrosis factor (TNF)-α levels, colonic nuclear factor-kappa-B (NF-κB) immunohistochemical expression, and the colonic histopathological changes were observed. RESULTS Metformin or/and α-LA attenuated the severity of the DSS-induced colitis through improving the reductions in body weights, the DAI, the colonic oxidative stress markers, TNF-α, and NF-κB levels, and the morphological mucosal damage scores. Significant synergetic therapeutic effects were observed with combined therapeutic regimens. CONCLUSION Therapeutically, metformin and α-LA could be administered in chronic colitis. The combination of currently used pharmaceutics with natural and synthetic potent antioxidant compounds will become a therapeutic strategy of choice for UC to improve the quality of life if sufficient clinical trials are available.

Abstract
OBJECTIVE To investigate the anti-inflammatory effects of decursin and decursinol angelate-rich Angelica gigas Nakai (AGNE) on dextran sulfate sodium (DSS)-induced murine ulcerative colitis (UC). METHODS The therapeutic effect of an AGNE was analyzed in a mouse model of UC induced by DSS. Disease activity index values were measured by clinical signs such as a weight loss, stool consistency, rectal bleeding and colon length. A histological analysis was performed using hematoxylin and eosin staining. Key inflammatory cytokines and mediators including IL-6, TNF-α, PGE2, COX-2 and HIF-1α were assayed by enzyme-linked immunosorbent assay or western blotting. RESULTS Treatment with the AGNE at 10, 20, and 40 mg/kg alleviated weight loss, decreased disease activity index scores, and reduced colon shortening in mice with DSS-induced UC. AGNE inhibited the production of IL-6 and TNF-α in serum and colon tissue. Moreover, AGNE suppressed the increased expression of COX-2 and HIF-1α and the increased production of PGE2 in colon tissue were observed in mice with DSS-induced UC. Additionally, histological damage was also alleviated by AGNE treatment. CONCLUSIONS The findings of this study verified that AGNE significantly improves clinical symptoms and reduces the activity of various inflammatory mediators. These results indicate the AGNE has the therapeutic potential in mice with DSS-induced UC.

Abstract
BACKGROUND Alternative medicine is widely accepted by public and becoming an attractive approach for treatment of various diseases. Glabridin (Gla), a major flavonoid present in licorice root, was reported to have antioxidant and anti-inflammatory properties. OBJECTIVE The study aimed to investigate the possible protective role of Gla against dextran sulphate sodium (DSS)-induced ulcerative colitis (UC) in rats and to clarify the molecular mechanisms underlying Gla function. METHODS Forty male Wistar rats were divided into control, colitis group (rats received 5% DSS in drinking water for 7 days), Gla group (50 mg/kg, orally, once daily), and sulfasalazine (SLZ) group (500 mg/kg, orally, once daily). Each of Gla and SLZ was administered 1 week ahead of DSS and parallel with its administration. RESULTS Gla ameliorated the inflammatory alterations induced by DSS. Gla group showed a reduction in colon concentration of tumor necrosis factor-alpha (TNF-α) and a decreased colon myeloperoxidase activity (MPO). Gla treatment downregulated inducible nitric oxide synthase (iNOS) gene expression in rat colon with a decreased content of nitric oxide (NO). Gla also increased cyclic AMP (cAMP) concentration in rat colon compared to colitis group. Such findings were comparable to or even better than those obtained by SLZ treatment. The histological features of UC such as ulceration and inflammatory cell infiltrations were improved in rat group treated by Gla. CONCLUSION Gla proved a potent anti-inflammatory role in UC through different mechanisms and, being a natural product, it could be safely used as a protective measure in inflammatory bowel diseases.
