Abstract
Background: Imbalances in gut microbiota and subsequent destabilization of intestinal barrier equilibrium have been related to the evolution of metabolic disorders. Goji berries (Lycium barbarum; GB) and their fermented counterpart (FGB) have been identified for their prebiotic capacity in managing intestinal barrier functions and inflammatory profiles Consequently, this research was designed to investigate the effects of supplementing GB and FGB on intestinal integrity, inflammation, and changes in the composition of gut microbiota in high-fat (HF)-fed rats. Materials and Methods: Thirty-two male Sprague-Dawley rats (6 weeks old, 8 per group) were divided into four categories based on their weight and provided with either respective diets over a 6-week period: low-fat (LF; 10% of calories from fat), HF (45% of calories from fat), and HF diets supplemented with either GB or FGB at a 2% (w/w). Results: Supplementation of GB and FGB resulted in compositional changes in the gut microbiota, denoted by a distinct abundance of Faecalibacterium prausnitzii with GB and Akkermansia muciniphila species with FGB, which have been linked to ameliorated obesity phenotypes and metabolic parameters. These alterations were correlated with enhancements in gut barrier integrity, thereby protecting against local and systemic inflammation induced by a HF diet. Supplementation with GB and FGB also mitigated lipopolysaccharide-induced inflammation through inhibition of its downstream pathway. Conclusion: These findings indicate that both GB and FGB supplementation can improve gut barrier function and inflammatory profiles in HF-fed rats via modulation of the microbial composition of the gut, supporting the potential application of GB and FGB in improving gut barrier function and managing inflammation amid metabolic challenges.

Anthocyanins and Probiotics Attenuate Dextran Sulfate Sodium-Induced Colitis: Evidence from an Experimental Animal Model. Foods 2024; 13:1987. [PMID: 38998493 PMCID: PMC11241346 DOI: 10.3390/foods13131987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2024] [Revised: 06/10/2024] [Accepted: 06/20/2024] [Indexed: 07/14/2024] Open
Abstract
Haskap berry (Lonicera caerulea L.) is a rich dietary source of anthocyanins with potent anti-inflammatory properties. In this study, isolated haskap berry anthocyanins were encapsulated in maltodextrin and inulin (3:1) by freeze-drying to improve stability and bioavailability. The structural properties of microcapsules, encapsulation yield, efficiency, recovery, and powder retention were evaluated. The microcapsules that exhibited the highest encapsulation efficiency (60%) and anthocyanin recovery (89%) were used in the dextran sulfate sodium (DSS)-induced acute colitis in mice. Thirty-five BALB/c male mice of seven weeks old were divided into seven dietary supplementation groups (n = 5) to receive either free anthocyanins, encapsulated anthocyanins (6.2 mg/day), or probiotics (1 × 109 CFU/day) alone or as combinations of anthocyanin and probiotics. As observed by clinical data, free anthocyanin and probiotic supplementation significantly reduced the severity of colitis. The supplementary diets suppressed the DSS-induced elevation of serum inflammatory (interleukin (IL)-6 and tumor necrosis factor) and apoptosis markers (B-cell lymphoma 2 and Bcl-2-associated X protein) in mice colon tissues. The free anthocyanins and probiotics significantly reduced the serum IL-6 levels. In conclusion, the dietary supplementation of haskap berry anthocyanins and probiotics protects against DSS-induced colitis possibly by attenuating mucosal inflammation, and this combination has the potential as a health-promoting dietary supplement and nutraceutical.

Lycium barbarum arabinogalactan alleviates intestinal mucosal damage in mice by restoring intestinal microbes and mucin O-glycans. Carbohydr Polym 2024; 330:121882.

Abstract
Structurally defined arabinogalactan (LBP-3) from Lycium barbarum have effect on improving intestinal barrier function. However, whether its intestinal barrier function depended on the changes of intestinal mucin O-glycans have not been investigated. A dextran sodium sulfate-induced acute colitis mouse model was employed to test prevention and treatment with LBP-3. The intestinal microbiota as well as colonic mucin O-glycan profiles were analyzed. Supplementation with LBP-3 inhibited harmful bacteria, including Desulfovibrionaceae, Enterobacteriaceae, and Helicobacteraceae while significantly increased the abundance of beneficial bacteria (e.g., Lachnospiraceae, Ruminococcaceae, and Lactobacillaceae). Notably, LBP-3 augmented the content of neutral O-glycans by stimulating the fucosylation glycoforms (F1H1N2 and F1H2N2), short-chain sulfated O-glycans (S1F1H1N2, S1H1N2, and S1H2N3), and sialylated medium- and long-chain O-glycans (F1H2N2A1, H2N3A1, and F1H3N2A1). In summary, we report that supplement LBP-3 significantly reduced pathological symptoms, restored the bacterial community, and promoted the expression of O-glycans to successfully prevent and alleviate colitis in a mouse model, especially in the LBP-3 prevention testing group. The underlying mechanism of action was investigated using glycomics to better clarify which the structurally defined LBP-3 were responsible for its beneficial effect against ulcerative colitis and assess its use as a functional food or pharmaceutical supplement.

Abstract
Inflammatory bowel disease (IBD) is a condition characterized by disrupted intestinal barrier function, abnormal immune response, and mucosal structure loss. This study evaluated the beneficial role of purple potato (PP) supplementation against IBD symptoms using a murine model of dextran sulfate sodium (DSS)-induced colitis, and further explored the underlying mechanisms. Six-week-old C57BL/6J male mice were randomized into two groups and fed a standard rodent diet with or without 10% PP powder for 7 weeks. At the 5th week of dietary supplements, mice in each group were further divided into two subgroups and were either induced with or without 2.5% DSS induction for 7 days, followed by 7 days of recovery. Data showed that PP supplementation ameliorated the disease activity index in DSS-treated mice and reversed the colonic structure loss, mucosal damage, macrophage infiltration, and pro-inflammatory cytokine secretion induced by DSS in the colonic tissue. PP supplementation also restored the levels of tight junction proteins and caudal type homeobox 2 in DSS-treated mice. Furthermore, dietary PP enhanced peroxisome proliferator-activated receptor-γ coactivator-1α signaling pathway, mitochondrial biogenesis, mitochondrial proteostasis, and protein-folding capacity. In summary, dietary PP ameliorated DSS-induced colitis and improved gut structures and barrier function, which was associated with improved mitochondrial function. These results support further investigation of PP as a potential dietary intervention for IBD.

Porcine Intestinal Mucosal Peptides Target Macrophage-Modulated Inflammation and Alleviate Intestinal Homeostasis in Dextrose Sodium Sulfate-Induced Colitis in Mice. Foods 2024; 13:162. [PMID: 38201190 PMCID: PMC10778919 DOI: 10.3390/foods13010162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 12/28/2023] [Accepted: 12/31/2023] [Indexed: 01/12/2024] Open
Abstract
Porcine intestinal mucosal proteins are novel animal proteins that contain large amounts of free amino acids and peptides. Although porcine intestinal mucosal proteins are widely used in animal nutrition, the peptide bioactivities of their enzymatic products are not yet fully understood. In the present study, we investigated the effect of porcine intestinal mucosal peptides (PIMP) on the RAW264.7 cell model of LPS-induced inflammation. The mRNA expression of inflammatory factors (interleukin 6, tumor necrosis factor-α, and interleukin-1β) and nitrous oxide levels were all measured by quantitative real-time PCR and cyclooxygenase-2 protein expression measured by Western blot. To investigate the modulating effect of PIMP and to establish a model of dextran sodium sulfate (DSS)-induced colitis in mice, we examined the effects of hematoxylin-eosin staining, myeloperoxidase levels, pro-inflammatory factor mRNA content, tight junction protein expression, and changes in intestinal flora. Nuclear factor κB pathway protein levels were also assessed by Western blot. PIMP has been shown in vitro to control inflammatory responses and prevent the activation of key associated signaling pathways. PIMP at doses of 100 and 400 mg/kg/day also alleviated intestinal inflammatory responses, reduced tissue damage caused by DSS, and improved intestinal barrier function. In addition, PIMP at 400 mg/kg/day successfully repaired the dysregulated gut microbiota and increased short-chain fatty acid levels. These findings suggest that PIMP may positively influence inflammatory responses and alleviate colitis. This study is the first to demonstrate the potential of PIMP as a functional food for the prevention and treatment of colitis.

Abstract
Understanding how dietary polysaccharides affect mucin O-glycosylation and gut microbiota could provide various nutrition-based treatments. Here, the O-glycan profile of the colonic mucosa and gut microbiome were investigated in C57BL/6J mice fed six structurally diverse dietary polysaccharides and a mixture of six fibers. Dietary polysaccharides increased total O-glycans, mainly by stimulating neutral glycans. Highly branched arabinogalactan promoted terminally fucosylated core 1 O-glycans; whereas linear polysaccharides, including pectin, konjac glucomannan, inulin, and the fiber mixture, favored terminally di-fucosylated O-glycans. The last three polysaccharides also lowered the level of sulfated O-glycans and sialylated mono-fucosylated O-glycans. Varied monosaccharide composition in mixed polysaccharides had a synergistic beneficial effect, boosting fucosylated neutral glycans, decreasing acidic glycans, and stimulating microbial richness and diversity. Dietary polysaccharides containing arabinose and sulfate groups enhanced the relative abundances of Akkermansia and Muribaculaceae, respectively. The present comparison reveals the relationship between dietary polysaccharide structure, mucin O-glycan composition, and intestinal microorganisms.

Abstract
PURPOSE This study examined the protective effects and mechanism of Lycium barbarum polysaccharides (LBP) in the context of intestinal barrier function and intestinal microbiota in mice with dextran sulfate sodium (DSS)-induced chronic ulcerative colitis (UC). METHODS C57BL/6J male mice were assigned to a standard normal diet without DSS (control group), a normal diet with DSS (DSS group, 2% DSS given discontinuously for 3 weeks) or a normal diet supplemented with LBP (1% dry feed weight, LBP group, 2% DSS given discontinuously for 3 weeks) for a total of 8 weeks, at which point colonic tissues and caecal contents were collected. RESULTS LBP exerted a significant effect against colitis by increasing body weight, colon length, DAI and histopathological scores. LBP inhibited proinflammatory cytokines (IL-1β, IL-6, iNOS and TNF-α) expression, improved anti-inflammatory cytokine (IL-10) expression, promoted the expression of tight junction proteins (Occludin and ZO-1) via nuclear factor erythroid 2-related factor 2 (Nrf2) activation and decreased Claudin-2 expression to maintain the intestinal mucosal barrier. In addition, the abundances of some probiotics (Ruminococcaceae, Lactobacillus, Butyricicoccus, and Akkermansia) were decreased with DSS treatment but increased obviously with LBP treatment. And LBP reduced the abundance of conditional pathogens associated with UC (Mucispirillum and Sutterella). Furthermore, LBP improved the production of short-chain fatty acids (SCFAs), including acetic acid, propionic acid, butyric acid and isobutyric acid. CONCLUSION LBP can alleviate DSS-induced UC by regulating inflammatory cytokines and tight junction proteins. Moreover, LBP promotes probiotics, suppresses conditional pathogens and increases SCFAs production, showing a strong prebiotic effect.

Abstract
This study explores the protective properties and potential mechanisms of wheat-germ-derived peptide APEPEPAF (APE) against ulcerative colitis. Colitis mice induced by dextran sulfate sodium (DSS) were used as the animal model. The results showed that the APE peptide could alleviate colitis symptoms including weight loss, colon shortening, and histopathological changes. This peptide attenuated the generation of inflammatory cytokines by inhibiting the phosphorylation of protein kinase PKCζ (Thr410) and NF-κB transcriptional activity in DSS-induced mice, suggesting that APE ameliorates colitis inflammation by regulating the PKCζ/NF-κB signaling pathway. APE also preserved the barrier function of the colon by dose-dependently promoting the expression of tight junction proteins (claudin-1, zonula occluded-1, and occludin). In addition, APE significantly decreased the abundance of Bacteroides and increased the abundance of Dubosiella and Lachnospiraceae_UCG-006 to improve the intestinal flora imbalance in DSS-induced colitis mice. Therefore, wheat germ peptide APE can be used as a novel agent and dietary supplement to treat ulcerative colitis..

[PMID: 36552612 PMCID: PMC9774969 DOI: 10.3390/antiox11122404] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 11/30/2022] [Accepted: 12/01/2022] [Indexed: 12/11/2022] Open
Abstract
As the prevalence of inflammatory bowel diseases (IBD) rises, the etiology of IBD draws increasing attention. Glucoraphanin (GRP), enriched in cruciferous vegetables, is a precursor of sulforaphane, known to have anti-inflammatory and antioxidative effects. We hypothesized that dietary GRP supplementation can prevent mitochondrial dysfunction and oxidative stress in an acute colitis mouse model induced by dextran sulfate sodium (DSS). Eight-week-old mice were fed a regular rodent diet either supplemented with or without GRP. After 4 weeks of dietary treatments, half of the mice within each dietary group were subjected to 2.5% DSS treatment to induce colitis. Dietary GRP decreased DSS-induced body weight loss, disease activity index, and colon shortening. Glucoraphanin supplementation protected the colonic histological structure, suppressed inflammatory cytokines, interleukin (IL)-1β, IL-18, and tumor necrosis factor-α (TNF-α), and reduced macrophage infiltration in colonic tissues. Consistently, dietary GRP activated AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor-gamma coactivator (PGC)-1α, and nuclear factor erythroid 2-related factor 2 (NRF2) pathways in the colonic tissues of DSS-treated mice, which was associated with increased mitochondrial DNA and decreased content of the oxidative product 8-hydroxydeoxyguanosine (8-OHDG), a nucleotide oxidative product of DNA. In conclusion, dietary GRP attenuated mitochondrial dysfunction, inflammatory response, and oxidative stress induced by DSS, suggesting that dietary GRP provides a dietary strategy to alleviate IBD symptoms.

Abstract
Ulcerative colitis (UC) is an inflammatory disease with chronic relapsing symptoms. This study investigated the effects of Lycium barbarum polysaccharides (LBP) and capsaicin (CAP) in dextran sulfate sodium (DSS)-induced UC rats. Rats were divided into normal, DSS-induced UC, and UC treated with 100 mg LBP/kg bw, 12 mg CAP/kg bw, or 50 mg LBP/kg bw and 6 mg CAP/kg bw. Rats were fed LBP or CAP orally by gavage for 4 weeks, and UC model was established by feeding 5% DSS in drinking water for 6 days during week 3. Oral CAP and mixture significantly reduced disease activity index. Oral LBP significantly decreased serum malondialdehyde, interleukin (IL)-6, colonic tumor necrosis factor (TNF)-α levels, and protein expression of transient receptor potential cation channel V1 (TRPV1) and transient receptor potential ankyrin 1 (TRPA1), but increased serum catalase activity. Oral CAP significantly suppressed serum IL-6, colonic TRPV1 and TRPA1 protein expression, but elevated IL-10 levels, serum superoxide dismutase and catalase activities. The mixture of LBP and CAP significantly reduced serum IL-6, colonic TNF-α and TRPA1 protein. In conclusion, administration of LBP and/or CAP attenuate DSS-induced UC symptoms through inhibiting oxidative stress, proinflammatory cytokines, and protein expression of TRPV1 and TRPA1.

Abstract
Ulcerative colitis (UC) is a serious health condition and defined as inflammation in the colon. Untreated, UC can develop into colitis-associated cancer (CAC), for which effective medicines are not available. Natural products are a better choice to treat UC by alleviating the inflammation. Caffeic acid phenethyl ester (CAPE) is a phenolic compound and known for its beneficial effects, including antibacterial, anti-inflammatory, anti-diabetic, and anticancer. We aimed to study the effect of CAPE on dextran sulfate sodium (DSS)-induced UC in mouse model. Administration of CAPE to DSS-induced mice protected against colon damage by improving body weight of mice, reducing the weight of spleen, and increased colon length. In addition, administration of CAPE resulted reduced the activity of myeloperoxidase (MPO) and CD68+ positive cells. Furthermore, a significant decrease in the production of key cytokines and the expression of nuclear factor (p65-NF)-κB. Moreover, p65-NF-κB activation was reduced in lipopolysaccharide (LPS)-treated RAW 264.7 macrophage cells from mouse origin. CAPE treatment leads to the reduced expressions of intercellular adhesion molecules (ICAM)-1 and vascular cell adhesion molecules (VCAM), both are key cell adhesion molecules. The results of this study clearly indicate that CAPE can potentially control inflammation in the colon and can be used as a therapy for UC.

Abstract
Inflammatory bowel disease (IBD) is a chronic, multifactorial and inflammatory disease occurring in the colon tract. Bioactive polysaccharides from natural resources have attracted extensive attention due to their safety, accessibility and good bioactivities. In recent years, a variety of natural bioactive polysaccharides have been proven to possess anti-inflammatory effects on treating acute colitis. The objective of this review was to give an up-to-date review on the anti-inflammatory effects and mechanisms of natural polysaccharides on acute colitis. The anti-inflammatory effects of natural polysaccharides on acute colitis concerning clinical symptoms amelioration, colon tissue repairment, anti-oxidative stress alleviation, anti-inflammation, immune regulation, and gut microbiota modulation were comprehensively summarized. In addition, inducible murine models for assessing the anti-inflammatory effects of natural polysaccharides on acute colitis were also concluded. This review will offer the comprehensive understanding of anti-inflammatory mechanisms of natural polysaccharides in acute colitis, and render theoretical basis for the development and application of natural polysaccharides in drug and functional food.

Abstract
The prevalence of inflammatory bowel disease (IBD) is increasing, which is concerning because IBD is a known risk factor for the development of colorectal cancer. Emerging evidence highlights environmental factors, particularly dietary factors and gut microbiota dysbiosis, as pivotal inducers of IBD onset. Goji berry, an ancient tonic food and a nutraceutical supplement, contains a range of phytochemicals such as polysaccharides, carotenoids, and polyphenols. Among these phytochemicals, L. barbarum polysaccharides (LBPs) are the most important functional constituents, which have protective effects against oxidative stress, inflammation, and neurodegeneration. Recently, the beneficial effects of goji berry and associated LBPs consumption were linked to prebiotic effects, which can prevent dysbiosis associated with IBD. This review assessed pertinent literature on the protective effects of goji berry against IBD focusing on the gut microbiota and their metabolites in mediating the observed beneficial effects.

Goji Berry (Lycium barbarum) Supplementation during Pregnancy Influences Insulin Sensitivity in Rabbit Does but Not in Their Offspring. Animals (Basel) 2021; 12:ani12010039.

Abstract
This study investigated the effects of Goji berry (Lycium barbarum) dietary supplementation during pregnancy on insulin sensitivity of rabbit does and their offspring. Starting from two months before the artificial insemination, 75 New Zealand White does were fed only commercial standard diet (C) or supplemented with 1% (G1) and 3% (G3) of Goji berries. Their offspring received a standard diet but kept the nomenclature of the mother’s group. Fasting and intravenous glucose tolerance test-derived indices were estimated at 21 days of pregnancy on rabbit does and at 90 days of age on the offspring. No difference was found in the fasting indices, while the diet modulated the response to glucose load of rabbit does. In particular, G3 group had the lowest glucose concentrations 5 min after the bolus administration (p < 0.05) and, as a result, differed in the parameters calculated during the elimination phase such as the elimination rate constant (Kel), the half-life of the exogenous glucose load (t1/2), and apparent volume of distribution (Vd; for all, p < 0.05). The high dose of Goji supplementation could thus enhance the first-phase glucose-induced insulin secretion. Findings on the offspring were inconsistent and therefore a long-term effect of Goji supplementation during pregnancy could not be demonstrated. Further study on the effect of Goji on the secretory pathway of insulin could clarify its hypoglycaemic action, while different protocols are needed to investigate its potential effects on foetal programming.

Abstract
Along with the increased knowledge about the positive health effects of food bioactives, the eating habits of many individuals have changed to obtain higher nutritional benefits from foods. Fruits are among the most preferred food materials in this regard. In particular, berry fruits are important sources in the diet in terms of their high nutritional content including vitamins, minerals, and phenolic compounds. Berry fruits have remedial effects on several diseases and these health-promoting impacts are associated with their phenolic compounds which may vary depending on the type and variety of the fruit coupled with other factors including climate, agricultural conditions, etc. Most of the berries have outstanding beneficial roles in many body systems of humans such as gastrointestinal, cardiovascular, immune, and nervous systems. Furthermore, they are effective on some metabolic disorders and several types of cancer. In this review, the health-promoting effects of bioactive compounds in berry fruits are presented and the most recent in vivo, in vitro, and clinical studies are discussed from a food science and nutrition point of view.

Abstract
Naringin is a kind of multi-source food additive which has been explored broadly for its various biological activities and therapeutic potential. In the present study, the protective effect and mechanism of naringin on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice were investigated. The results showed that naringin significantly alleviated DSS-induced colitis symptoms, including disease activity index (DAI), colon length shortening, and colon pathological damage. The tissue and serum secretion of inflammatory cytokines, as well as the oxidative stress, were decreased accordingly upon naringin intervention. Naringin also decreased the proteins involved in inflammation and increased the expression of tight junction (TJ) proteins. Moreover, naringin increased the relative abundance of Firmicutes/Bacteroides and reduced the content of Proteobacteria to improve the intestinal flora disorder caused by DSS, which promotes the intestinal health of mice. It was concluded that naringin can significantly ameliorate the pathogenic symptoms of UC through inhibiting inflammatory response and regulating intestinal microbiota, which might be a promising natural therapeutic agent for the dietary treatment of UC and the improvement of intestinal symbiosis.

Lycium barbarum polysaccharides ameliorate LPS-induced inflammation of RAW264.7 cells and modify the behavioral score of peritonitis mice. J Food Biochem 2021; 45:e13889. [PMID: 34426988 DOI: 10.1111/jfbc.13889] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 06/26/2021] [Accepted: 07/19/2021] [Indexed: 01/17/2023]
Abstract
In the present study, the anti-inflammatory effect of Lycium barbarum polysaccharide (LBP) and the possible molecular mechanism thereof were examined, so as to perceive the pharmacological action of LBP. With acute peritonitis in mice as the inflammatory model, the protective effect of LBP on peritonitis mice was evaluated by recording the effect of behavioral scores, studying the pathological damage of intestine and liver, and detecting the levels of inflammatory cytokines. Additionally, by establishing an lipopolysaccharide (LPS)-induced RAW264.7 macrophage model, the effect of LBP on RAW264.7 cell phenotype and culture supernatant inflammatory markers was observed. Finally, the activation of inflammation-related target genes, such as iNOS, Toll-like receptor 4 (TLR4), nuclear factor-κB (NF-κB) p65, and IκBα, were further detected. The results reveal that pretreatment with LBP could decrease the behavioral score of inflammatory mice, inhibit the secretion of pro-inflammatory factors, and reduce liver and intestine injury. LBP can regulate the effect of lipopolysaccharide on the polarization of RAW264.7 cells, and reduce the production of NO and cytokines (TNF-α, IL-1β, IL-6). Further, LBP pretreatment was found to be able to significantly reduce the expression of iNOS, TLR4, NF-κB p65, and IκBα in macrophages. The present research provides evidence that LBP exerts potential anti-inflammatory activity in LPS-induced RAW264.7 macrophages via inhibiting TLR4 and NF-κB inflammatory sites and improving the behavior score of peritonitis mice. PRACTICAL APPLICATIONS: In recent years, the number of deaths worldwide has continued to rise as a result of inflammation. Despite said rise in deaths, many synthetic drugs with anti-inflammatory properties are significantly expensive and also have a host of side effects. Thus, the development of new anti-inflammatory drugs derived from medicinal plants has broad application potential. As such, in the present study, lipopolysaccharide (LPS)-induced macrophages were used to establish inflammatory cell models to verify the anti-inflammatory effect of Lycium barbarum polysaccharides (LBP). Findings were made that LBP could reduce the expression levels of inflammatory cytokines and NO by regulating macrophage polarization and NF-κB translocation, and thus, could exert anti-inflammatory activity. In addition, by intraperitoneal injection of LPS to establish peritonitis mice models, LBP pretreatment was found to have significantly modified the behavioral score of mice, while decreasing the secretion of inflammatory factors and the damage to several organs. The present study provides a basis for further understanding the effects of LBP in acute inflammation.

Abstract
Several studies are described that contribute to the systematic exploration of new aspects of digestion, fermentation, and biological activities of pectic polysaccharides (PPS) leading to a better understanding of prebiotics. Inflammatory bowel disease (IBD) is thought to be associated with the dysbacteriosis induced by different environmental agents in genetically susceptible persons. PPS are considered as an indispensable gut-microbiota-accessible carbohydrate that play a dominant role in maintaining gut microbiota balance and show a better effect in ameliorating IBD than some traditional prebiotics. The aim of this review is to summarize the fermentation characteristics of PPS, highlight its role in improving IBD, and propose a view that PPS may be a new and effective prebiotic.

Natural Food Polysaccharides Ameliorate Inflammatory Bowel Disease and Its Mechanisms. Foods 2021; 10:foods10061288. [PMID: 34199820 PMCID: PMC8227517 DOI: 10.3390/foods10061288] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 05/30/2021] [Accepted: 06/02/2021] [Indexed: 02/08/2023] Open
Abstract
Natural polysaccharides and their metabolites’ short chain fatty acids (SCFAs) have attracted much attention. Recently, they have shown great potential in attenuating systemic inflammation activities, especially in inflammatory bowel disease (IBD). IBD is a complex pathological process and is related to epithelial damage and microbiota imbalance in the gut. Recent studies have indicated that natural polysaccharides could improve IBD recovery by different mechanisms. They could not only influence the ratio of intestine microbiota, but also regulate the secretion levels of immunity cytokines through multiple pathways, the latter including modulation of the TLR/MAPK/NF-κB signaling pathways and stimulation of G-protein-coupled receptors. Moreover, they could increase intestinal integrity and modulate oxidative stress. In this review, recent research about how natural polysaccharides impact the pathogenesis of IBD are summarized to prove the association between polysaccharides and disease recovery, which might contribute to the secretion of inflammatory cytokines, improve intestine epithelial damage, reduce oxidative stress, sustain the balanced microenvironment of the intestines, and finally lower the risk of IBD.

Abstract
Intestinal barrier dysfunction and inflammatory cytokine secretion play crucial roles in inflammatory bowel disease (IBD). Herein, we investigated the protective effects of Tricholoma matsutake-derived peptides SDIKHFPF and SDLKHFPF against dextran sulfate sodium-induced colitis. Both peptides alleviated colitis signs, including diarrhea, weight loss, bloody stools, colon shortening, and histopathological changes, while reducing mucus destruction, goblet cell exhaustion, and intestinal permeability. SDIKHFPF and SDLKHFPF protected the barrier function by promoting the expression of tight junction (TJ) zonula occludens-1 and occludin within the colon, as well as attenuating colonic inflammation through myeloperoxidase and pro-inflammatory cytokine suppression. Western blotting indicated that the peptides suppressed myosin light chain kinase (MLCK) and nuclear factor kappa B (NF-κB) levels, inhibiting MLC phosphorylation. SDLKHFPF was more potent than SDIKHFPF. These findings suggest that peptide SDLKHFPF mitigates colitis by regulating TJ protein expression and pro-inflammatory cytokine production via NF-κB/MLCK/p-MLC signaling, improving the barrier function.

Sci Rep 2021; 11:8284. [PMID: 33859347 PMCID: PMC8050040 DOI: 10.1038/s41598-021-87814-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Accepted: 04/05/2021] [Indexed: 11/09/2022] Open
Abstract
Patients with ulcerative colitis are typically suspected of an inflammatory flare based on suggestive symptoms of inflammation. The aim of this study was to evaluate the impact of inflammation on colonic motility and rectal sensitivity from active to recovery of inflammation. Male rats were given drinking water with 5% dextran sulfate sodium for 7 days. Inflammation, intestinal motor and sensory functions were investigated weekly for 6 weeks. (1) The disease activity index score, fecal calprotectin and tumor necrosis factor alpha were increased from Day 0 to Day 7 (active inflammation) and then decreased gradually until recovery. (2) Distal colon transit was accelerated on Day 7, and then remained unchanged. Whole gut transit was delayed on Day 7 but accelerated from Day 14 to Day 42. (3) Rectal compliance was unaffected from Day 0 to Day 7, but decreased afterwards. (4) Rectal hypersensitivity was noted on Day 7 and persistent. (5) Plasma acetylcholine was decreased on Day 7 but increased from Day 14 to Day 42. Nerve growth factor was increased from Day 7 to Day 42. DSS-induced inflammation leads to visceral hypersensitivity that is sustained until the resolution of inflammation, probably mediated by NGF. Rectal compliance is reduced one week after the DSS-induced inflammation and the reduction is sustained until the resolution of inflammation. Gastrointestinal transit is also altered during and after active colonic inflammation.

Abstract
SCOPE As a natural compound in foods, alpha-ketoglutarate (aKG) is one of the key metabolites maintaining energy homeostasis. This study examines the beneficial effects of dietary aKG against the development of experimental colitis and further explores the underlying molecular mechanisms. METHODS AND RESULTS Eight-week-old male C57BL/6 mice receive drinking water with or without 1% aKG for 4 weeks. At week 3, colitis is induced by 2.5% dextran sulfate sodium (DSS) for 7 days followed by 7 days recovery. Dietary aKG supplementation decreases DSS-induced body weight loss, gross bleeding, fecal consistency score, and disease activity index. In agreement, aKG supplementation restores DSS-associated colon shortening, ameliorated mucosal damage, and macrophage infiltration into colonic tissue, which are associated with suppressed gut inflammation and Wnt signaling, and improved epithelial structure. Consistently, aKG supplementation enhances M1 to M2 macrophage polarization and strengthens intestinal barrier function. Additionally, aKG supplementation elevates colonic aKG levels while decreasing 2-hydroxyglutarate levels, which increases oxidative instead of glycolytic metabolism. CONCLUSION aKG supplementation protects against epithelial damage and ameliorates DSS-induced colitis, which are associated with suppressed inflammation, Wnt signaling pathway, and glycolysis. Intake of foods enriched with aKG or aKG supplementation can be an alternative approach for the prevention or treatment of colitis that are common in Western societies.

Abstract
In this study, a colitis mouse model induced by dextran sulfate sodium (DSS) was used to investigate the mechanisms of action of an extract of crude polysaccharides (POL) from Physalis pubescens L. as a dietary intervention for colitis. Our results showed that the administration of POL prior to DSS-induced colitis protected the colon mucosal layer; maintained intestinal barrier integrity; alleviated oxidative damage; and lowered neutrophil infiltration by downregulating intercellular cell adhesion molecule-1 and monocyte chemoattractant protein-1 expression. More importantly, POL pretreatment reduced the expression of the proinflammatory factors tumor necrosis factor-α, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2), thereby modulating the nuclear factor-κB/iNOS-COX-2 signal transduction pathway. In addition, POL reversed DSS-induced gut dysbiosis, accompanied by reducing the relative abundance of Helicobacter, Mucispirillum, and Erysipelatoclostridium. In conclusion, POL ameliorated DSS-induced intestinal injury in mice, indicating that POL could be a useful dietary nutrient to protect against colitis. PRACTICAL APPLICATION: Physalis pubescens L. is an edible fruit. The results of this study show that the intervention with Physalis pubescens L. crude polysaccharides may help prevent ulcerative colitis.

Grape pomace inhibits colon carcinogenesis by suppressing cell proliferation and inducing epigenetic modifications. J Nutr Biochem 2020; 84:108443.

Abstract
Grape pomace (GP), a by-product of the wine and juice industry, is rich in bioflavonoids and dietary fibers. We hypothesized that GP has protective effects against colitis-associated colorectal cancer (CRC). Nine-week-old female mice were fed a control diet (CON) or CON with 5% grape pomace (GP) for 2 weeks, when mice were subjected to azoxymethane (AOM)/dextran sulfate sodium (DSS) induced-CRC induction. GP supplementation ameliorated the disease activity index (DAI) score, reduced tumor number, tumor size and pathological scores in AOM/DSS treated mice. Furthermore, dietary GP suppressed colonic expression of inflammatory cytokines, IL-1β and TNF-α, and inhibited NF-κB inflammatory signaling, while increased anti-inflammatory cytokine TGF-β mRNA expression. Colorectal inflammation is known to enhance Wnt signaling and cell proliferation. In agreement, the content of β-catenin, a key downstream mediator of Wnt signaling, was reduced as was the expression of Cyclin D1, phosphorylation and content of p53 and PCNA level in GP-fed mice. In addition, GP reduced the expression of ALDH1, a marker of cell stemness, and increased the expression of Cdx2, a key transcription factor initiating epithelial cell differentiation, DNA methylation of the promoter region of Cdx2 gene and hypermethylation of CpG island methylator phenotype (CIMP), which commonly occurs during CRC carcinogenesis, was alleviated in the GP group. In conclusion, GP supplementation suppressed colitis-associated CRC carcinogenesis, which was associated with the suppression of inflammation and cell proliferation and the enhancement of DNA demethylation in Cdx2 and CIMP genes in the colon. These data suggest that dietary GP supplementation has preventive effects against colorectal carcinogenesis.

Abstract
We used a multi-omics profiling approach to investigate the suppressive effects of 2% Wolfberry (WOL)-enriched diets on dextran sodium sulfate (DSS)-induced colitis in mice. It was observed that in mice fed the WOL diet, the disease activity index, colon shortening, plasma concentrations of matrix metalloproteinase-3 and relative mesenteric fat weight were significantly improved as compared to the DSS group. Results from colon transcriptome and proteome profiles showed that WOL supplementation significantly ameliorated the expression of genes and proteins associated with the integrity of the colonic mucosal wall and colonic inflammation. Based on the hepatic transcriptome, proteome and metabolome data, genes involved in fatty acid metabolism, proteins involved in inflammation and metabolites related to glycolysis were downregulated in WOL mice, leading to lowered inflammation and changes in these molecules may have led to improvement in body weight loss. The integrated nutrigenomic approach thus revealed the molecular mechanisms underlying the ameliorative effect of whole WOL fruit consumption on inflammatory bowel disease.

Abstract
Maqui berry (Aristotelia chilensis) is an edible berry. The study aimed to explore the therapeutic effect of maqui berry on inflammatory bowel disease. Maqui berry water extract was separated by multiple solvents extraction. The chemical bases, antioxidant and anti-inflammatory properties of different extract fractions were then compared. Dextran sodium sulfate (DSS)-induced ulcerative colitis mice were used for the pharmacological activity test in vivo. Experimental results showed that the ethyl acetate fraction of maqui berry water extract (MWE) was rich in phenols and exhibited good antioxidant and anti-inflammatory activities. MWE considerably reduced the expression of COX2 and IL-6 in LPS-stimulated RAW 264.7 cells. Inflammatory bowel disease index, MDA, NO, i-NOS, and COX2 in colon tissues and MPO, TNF-α, and IL-1β in blood serums were remarkably decreased in the treatment group compared to in the model group (p < 0.05). Intestinal histopathological damage was significantly alleviated in the treatment group, and the expression of occludin was increased (p < 0.05). MWE treatment alleviated the imbalance of gut microbiota caused by DSS injury. Overall, MWE plays a therapeutic role in ulcerative colitis through its anti-inflammatory effect, reduces immune stress, and regulates gut microbiota.

Abstract
In this study, the effects of 2-O-β-d-glucopyranosyl-l-ascorbic acid (AA-2βG), a natural ascorbic acid derivative from the fruits of Lycium barbarum, on treating the dextran sulfate sodium (DSS)-induced colitis in mice were investigated. The results revealed that AA-2βG had palliating effects on DSS-induced inflammatory bowel disease (IBD) in terms of slowing down the trends of body weight and solid fecal mass loss, reducing colitis disease activity index, improving serum physiological and biochemical indicators, increasing colon length, blocking proinflammatory cytokines, and increasing tight junction proteins. Additionally, AA-2βG treatment could promote the production of short-chain fatty acids and modulate the composition of the gut microbiota. The key bacteria related to IBD were found to be Porphyromonadaceae, Prevotellaceae, Rikenellaceae, Parasutterella, Parabacteroides, and Clostridium. The results indicated that AA-2βG might treat IBD through the regulation of gut microbiota, suggesting that AA-2βG has the potential to be used as a dietary supplement in the treatment of IBD.

Abstract
Neutral polysaccharides from Ningxia L. barbarum fruit have been reported with immunomodulatory and antioxidative biological activities. Few studies on pectic polysaccharides have been reported, especially not from the Xinjiang L. barbarum. In the present study, a pectic polysaccharide, XLBP-I-I, was obtained from water decoction of Xinjiang L. barbarum using anion exchange chromatography and gel filtration. The results from methanolysis, methylation, FT-IR and NMR experiments indicated that XLBP-I-I was a typical pectic polysaccharide. In vitro assay showed that XLBP-I-I could reduce the ER stress and UPR in tunicamycin insult IPEC-J2 cells, and further protect IPEC-J2 cells against apoptosis induced by ER stress. These results reveal a new perspective for pectic L. barbarum polysaccharides on intestine ER stress, and this elicited interests for its further applications.

Abstract
This study is aimed to investigate the ameliorative effect of resveratrol in a dextran sodium sulfate (DSS)-induced colitis mouse model and intestinal Caco-2 cells, focusing on neutrophil infiltration and tight junction (TJ) barriers. DSS administration caused body weight loss (day8, control 104 ± 1, DSS 72 ± 2%, p < 0.05), shortening of colon length (control 5.1 ± 0.1, DSS 3.8 ± 0.1 cm, p < 0.05), pro-inflammatory cytokines increase-including interleukin (IL)-1β (control 1.0 ± 0.2, DSS 58.5 ± 29.6 arbitrary unit (AU), p < 0.05), IL-6 (control 1.0 ± 0.3, DSS 312 ± 82 AU, p < 0.05), and chemokine motif ligand 2 (CXCL-2, a murine IL-8 homologue, control 1.0 ± 0.4, DSS 696 ± 262 AU, p < 0.05), decreased TJ proteins (e.g., occludin, control 1.0 ± 0.05, DSS 0.11 ± 0.03 AU, p < 0.05), and neutrophil infiltration (control 1.2 ± 0.2, DSS 25.9 ± 1.1 cells, p < 0.05). Supplemental resveratrol (0.1% (w/w) in the diet) partially or totally reversed these symptoms (body weight change 100 ± 1, colon length 4.6 ± 0.1; IL-1β 5.9 ± 1.8, IL-6 10 ± 3, CXCL-2 14 ± 7, occludin 0.76 ± 0.06, neutrophil infiltration 9.3 ± 0.7, p < 0.05). Pretreatment of intestinal Caco-2 cells with resveratrol suppressed the TNF-α-induced production of IL-8 (control 1.00 ± 0.04, TNFα 3.40 ± 0.16, TNFα+Res 1.81 ± 0.28 AU, p < 0.05) and phosphorylation of the inflammatory signaling molecules including NF-κB, extracellular signal-regulated kinase and stress c-Jun N-terminal protein kinase. Collectively, the reduction of TJ barrier defect and IL-8 in intestinal cells, leading to reduced neutrophil infiltration into colonic tissues, appears to be one of the central mechanisms for the resveratrol-mediated effect.

Abstract
SCOPE This study examines the beneficial effects of Goji berry against spontaneous colitis and its prebiotic role in IL-10-deficient mice. METHODS IL-10-deficient mice are assigned to a standard rodent diet (control) or a control diet supplemented with Goji (1% of dry feed weight) for 10 weeks, at which point colonic tissues and fecal contents are collected. RESULTS Goji supplementation decreases colonic pathobiological scores and mRNA expression of Il17a and Tgfb1, while it enhances Muc1 expression and fecal IgA content. Illumina MiSeq sequencing reveals that Goji supplementation increases Actinobacteria phylum, resulting in a bloom of Bifidobacteria in gut microbiota. Additionally, dietary Goji promotes butyrate-producing bacteria including Lachnospiraceae-Ruminococcaceae family and Roseburia spp. under Clostridium cluster XIVa. Furthermore, butyrate-producers Clostridium leptum and its dominant constituent Fecalibacterium prazusnitzii are markedly increased in the Goji group. Moreover, the gene-encoding butyryl-coenzyme A CoA transferase, a key enzyme responsible for butyrate synthesis in butyrate-producing bacteria, is increased sixfold in the fecal samples of Goji group associated with increased fecal butyrate content. CONCLUSION Data collectively show that dietary Goji results in the blooming of Bifidobacteria and butyrate-producing bacteria. These bacteria may cross-feed each other, conferring preventative effects against colitis in IL-10-deficient mice.

Abstract
Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory disorder. A wealth of data pointed out that various aspects of chronic inflammation may be affected by several specific dietary factors. This paper calls attention to anthocyanins enriched plant food and anthocyanin dietary supplements, whose role in the management of IBD and its associated oncogenesis deems crucial. Area covered: We updated the most relevant dietary anthocyanins with potential anti-colitis and preventive effect on inflammatory associated colorectal cancer based on the recent animal and human researches along with revealing the major cellular and molecular mechanisms of action. Mounting evidence reported that anthocyanins enriched plant foods perform their protective role on IBD and inflammatory-induced colorectal cancer via different cellular transduction signaling pathways, including inflammatory transcription factors, SAPK/JNK and p38 MAPK cascade, JAK/STAT signaling, NF-kB/pERK/MAPK, Wnt signaling pathway, Nrf2 cytoprotective pathway as well as AMPK pathway and autophagy. Expert commentary: Combination of anthocyanins enriched dietary supplements with existing medications can provide new therapeutic options for IBD patients. Further, well-designed randomized control trials (RCTs) are essential to evaluate the role of anthocyanins enriched medicinal foods as well as isolated anthocyanin components as promising preventive and therapeutic dietary agents for IBD and its associated oncogenesis.

Abstract
Inflammatory bowel disease (IBD) is a chronically relapsing inflammatory disorder of the gastrointestinal tract. Current IBD treatments are associated with poor tolerability and insufficient therapeutic efficacy, prompting the need for alternative therapeutic approaches. Recent advances suggest promising interventions based on a number of phytochemicals. Herein, we explored the beneficial effects of tussilagone, a major component of Tussilago farfara, in mice subjected to acute colitis induced by dextran sulfate sodium (DSS). Treatment with tussilagone resulted in a significant protective effect against DSS-induced acute colitis in mice via amelioration of weight loss, and attenuation of colonic inflammatory damage. Additionally, the expression of tumor necrosis factor-α and interleukin-6 and the activity of myeloperoxidase in colonic tissues were significantly reduced in tussilagone-treated mice. Furthermore, immunohistochemical analysis revealed that tussilagone treatment reduced the numbers of nuclear factor-kappa B (NF-κB) and increased the numbers of nuclear factor erythroid 2-related factor 2 (Nrf2) in nuclei of colonic tissues. Taken together, tussilagone treatment attenuated DSS-induced colitis in mice through inhibiting the activation of NF-κB and inducing Nrf2 pathways, indicating that tussilagone is a potent therapeutic candidate for treatment of intestinal inflammation.

Abstract
BACKGROUND Ulcerative colitis causes recurring intestinal mucosal injury and sustained inflammation, increasing the likelihood of colorectal cancer (CRC) development. Dietary red raspberry (RB) is a rich source of phytonutrients known to have anti-inflammatory activity; however, the role of RB on CRC prevention in chronic colitis has not been examined. OBJECTIVE This study examined the effects of dietary RB supplementation on inflammation, epithelium repair, and oncogenic signaling in dextran sulfate sodium (DSS)-induced chronic colitis in mice. METHODS Six-week-old male C57BL/6J mice were fed a control or RB (5% of dry feed weight; n = 12/group) diet for 10 wk. Starting from the fourth week, mice were administered 2 repeated cycles of 1% DSS (7-d DSS treatment plus 14-d recovery) and were monitored daily for disease activity index (DAI) score. Colonic tissues were collected at the end of the study for histochemical, immunohistochemical, and biochemical analysis of inflammation, differentiation and proliferation markers. RESULTS RB supplementation reduced the DAI score and histologic damage (by 38.9%; P ≤ 0.01), expression of inflammatory mediators (by 20-70%; P ≤ 0.01), infiltration of CD4 T cells (by 50%; P ≤ 0.05), and α4β7 integrin and related adhesion molecules (by 33.3%; P ≤ 0.01). Furthermore, RB supplementation facilitated epithelium repair, as evidenced by enhanced goblet cell density, expression of transcription factors including Kruppel-like factor 4 (Klf4) and Hairy and enhancer of split 1 (Hes1), terminal differentiation markers, mucin 2 (Muc2), and intestinal alkaline phosphatase (by 20-200%; P ≤ 0.01). Conversely, proliferating cell nuclear antigen (by 70%; P ≤ 0.01), β-catenin, and signal transducer and activator of transcription 3 (STAT3) signaling (by 19-33%; P ≤ 0.05) were reduced by RB supplementation. In addition, RB supplementation enhanced p53 stability (by 53%) and reduced oncogenic gene expression (by 50-60%). CONCLUSION RB supplementation reduced DAI score and the risk of CRC development during recurring colitis in mice, suggesting that RB is a possible dietary supplement for patients with ulcerative colitis and related gut inflammatory diseases.

Abstract
Persistent intestinal inflammation severely impairs intestinal integrity resulting in inflammatory bowel disease. Red raspberries (RB) are a rich source of bioactive compounds; their beneficial effect on the colitis protection was evaluated in the current study using a dextran sulfate sodium (DSS)-induced acute colitis mouse model. Six-week-old mice were fed a standard rodent research diet supplemented with RB (0 or 5% w/w, n=20 each group) for 6 weeks. At the 4th week of dietary treatment, approximately half of mice in each dietary group (n=12 each group) were subjected to 2.5% DSS induction for 6 days, followed by 6 days of recovery, to induce colitis. RB supplementation decreased body weight loss (P≤.01), disease activity index (P≤.01), and colon shortening (P≤.05) in DSS-treated mice. In addition, RB supplementation protected the colonic structure (P≤.01), associated with suppressed NF-κB signaling and reduced expression of inflammatory interleukin (IL)-1β, IL-6, IL-17, cyclooxegenase-2, and tumor necrosis factor-α in DSS-treated mice. RB supplementation reduced neutrophil infiltration, monocyte chemoattractant protein-1 mRNA expression, and xanthine oxidase content, but enhanced catalase content in DSS-treated mice. Consistently, RB supplementation reduced pore forming tight junction protein claudin-2, increased barrier strengthening claudin-3, zonula occluden-1 protein content and mucin (MUC)-2 mRNA level, and activated AMP-activated protein kinase (AMPK) in DSS-treated mice. In conclusion, dietary RB protected against inflammation and colitis symptoms induced by DSS, providing a promising dietary approach for the management of colitis.

Abstract
Obesity is a risk factor for developing inflammatory bowel disease. Pea is unique with its high content of dietary fiber, polyphenolics, and glycoproteins, all of which are known to be health beneficial. We aimed to investigate the impact of green pea (GP) supplementation on the susceptibility of high-fat diet (HFD)-fed mice to dextran sulfate sodium (DSS)-induced colitis. Six-week-old C57BL/6J female mice were fed a 45% HFD or HFD supplemented with 10% GP. After 7-week dietary supplementation, colitis was induced by adding 2.5% DSS in drinking water for 7 days followed by a 7-day recovery period. GP supplementation ameliorated the disease activity index score in HFD-fed mice during the recovery stage, and reduced neutrophil infiltration, mRNA expression of monocyte chemoattractant protein-1 (MCP-1) and inflammatory markers interleukin (IL)-6, cyclooxygenase-2 (COX-2), IL-17, interferon-γ (IFN-γ), and inducible nitric oxide synthase (iNOS) in HFD-fed mice. Further, GP supplementation increased mucin 2 content and mRNA expression of goblet cell differentiation markers including Trefoil factor 3 (Tff3), Krüppel-like factor 4 (Klf4), and SAM pointed domain ETS factor 1 (Spdef1) in HFD-fed mice. In addition, GP ameliorated endoplasmic reticulum (ER) stress as indicated by the reduced expression of Activating transcription factor-6 (ATF-6) protein and its target genes chaperone protein glucose-regulated protein 78 (Grp78), the CCAAT-enhancer-binding protein homologous protein (CHOP), the ER degradation-enhancing α-mannosidase-like 1 protein (Edem1), and the X-box binding protein 1 (Xbp1) in HFD-fed mice. In conclusion, GP supplementation ameliorated the severity of DSS-induced colitis in HFD-fed mice, which was associated with the suppression of inflammation, mucin depletion, and ER stress in the colon.

Abstract
OBJECTIVE Maternal high-fat diet (HFD) may alter the offspring intestinal immune system, thereby enhancing susceptibility toward inflammatory bowel disease. The objective of the current study was to investigate the impact of maternal HFD on offspring intestinal health using a mouse model of dextran sulfate sodium (DSS)-induced colitis. METHODS Dams were provided with either HFD (60%) or control diet. After weaning, female offspring from both groups were kept on 45% HFD. At 14 weeks of age, offspring were subjected to 2.5% DSS in drinking water for 5 days, followed by 5 days of recovery. RESULTS Offspring from maternal HFD had higher body weight gain before DSS induction and had higher liver and fat weights with increased adipocyte size at necropsy. When subjected to DSS treatment, HFD offspring had accelerated body weight loss and exaggerated disease activity index. HFD offspring had an elevated histopathological score and interleukin (IL)-1β, IL-6, and IL-17 expression with upregulated NF-κB signaling. Maternal HFD resulted in enhanced neutrophil infiltration associated with elevated expression of monocyte chemoattractant protein-1. Furthermore, maternal HFD suppressed AMP-activated protein kinase activity and decreased sirtuin 1 and p53 protein contents in offspring gut. CONCLUSIONS Maternal HFD consumption predisposes offspring to a higher susceptibility to develop inflammatory bowel disease.

Abstract
Impairment in gut epithelial integrity and barrier function is associated with many diseases. The homeostasis of intestinal barrier is based on a delicate regulation of epithelial proliferation and differentiation. AMP-activated protein kinase (AMPK) is a master regulator of energy metabolism, and cellular metabolites are intrinsically involved in epigenetic modifications governing cell differentiation. We aimed to evaluate the regulatory role of AMPK on intestinal epithelial development and barrier function. In this study, AMPK activator (AICAR) improved the barrier function of Caco-2 cells as indicated by increased transepithelial electrical resistance and reduced paracellular FITC-dextran permeability; consistently, AICAR enhanced epithelial differentiation and tight junction formation. Transfection of Caco-2 cells with AMPK WT plasmid, which enhances AMPK activity, improved epithelial barrier function and epithelial differentiation, while K45R (AMPK dominant negative mutant) impaired; these changes were correlated with the expression of caudal type homeobox 2 (CDX2), the key transcription factor committing cells to intestinal epithelial lineage. CDX2 deficiency abolished intestinal differentiation promoted by AMPK activation. Mechanistically, AMPK inactivation was associated with polycomb repressive complex 2 regulated enrichment of H3K27me3, the inhibitory histone modification, and lysine-specific histone demethylase-1-mediated reduction of H3K4me3, a permissive histone modification. Those histone modifications provide a mechanistic link between AMPK and CDX2 expression. Consistently, epithelial AMPK knockout in vivo reduced CDX2 expression, impaired intestinal barrier function, integrity and ultrastructure of tight junction, and epithelial cell migration, promoted intestinal proliferation and exaggerated dextran sulfate sodium-induced colitis. In summary, AMPK enhances intestinal barrier function and epithelial differentiation via promoting CDX2 expression, which is partially mediated by altered histone modifications in the Cdx2 promoter.
