Effects of wolfberry ( Lycium barbarum) consumption on the human plasma lipidome and its association with cardiovascular disease risk factors: a randomized controlled trial of middle-aged and older adults. Front Nutr 2024; 11:1258570. [PMID: 38439925 PMCID: PMC10909962 DOI: 10.3389/fnut.2024.1258570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 02/05/2024] [Indexed: 03/06/2024] Open
Abstract
Background Long-term wolfberry intake as part of a healthy dietary pattern was recognized to have beneficial vascular outcomes. Characterization of the plasma lipidome may further provide comprehensive insights into pathways underlying these cardiovascular protective effects. Objective We analyzed the plasma lipidome of subjects who adhered to a healthy dietary pattern either with or without wolfberry and investigated the associations between the plasma lipidomic profile and cardiovascular health-related indicators. Methods In this 16-week, parallel design, randomized controlled trial, middle-aged and older adults (n = 41) were provided dietary counseling and assigned to either consume or not consume 15 g of wolfberry daily. At baseline and post-intervention, plasma lipidomics was assayed, and its relationships with classical CVD risk factors, vascular health, oxidant burden, carotenoids status, body composition, and anthropometry were examined. Results From the plasma lipidome, 427 lipid species from 26 sub-classes were quantified. In the wolfberry and control groups, significant changes were prominent for 27 and 42 lipid species, respectively (P < 0.05 with > 0.2-fold change). Fold changes for seven lipid species were also markedly different between the two groups. Examining the relationships between the plasma lipidome and CVD-related risk factors, total cholesterol revealed a marked positive correlation with 13 ceramide species, while HDL-cholesterol which was notably increased with wolfberry consumption showed a positive correlation with 10 phosphatidylcholine species. Oxidant burden, as represented by plasma 8-isoprostanes, was also inversely associated with lipidomic triglycerides and ether-triglycerides (41 species) and directly associated with hexosylceramides (eight species) and sphingomyelins (six species). There were no differential associations with CVD risk detected between groups. Conclusion Characteristic alterations to the plasma lipidome were observed with healthy dietary pattern adherence and wolfberry consumption. An examination of these fluctuations suggests potential biochemical mechanisms that may mediate the antioxidant and cardiovascular protective effects of healthy dietary pattern adherence and wolfberry intake. This study was registered at clinicaltrials.gov as NCT0353584.

Lycium barbarum polysaccharide alleviates DSS-induced chronic ulcerative colitis by restoring intestinal barrier function and modulating gut microbiota. Ann Med 2023; 55:2290213. [PMID: 38061697 PMCID: PMC10836275 DOI: 10.1080/07853890.2023.2290213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 11/26/2023] [Indexed: 12/18/2023] Open
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
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.

Abstract
PURPOSE Wolfberry is rich in bioactive compounds which may lower cardiovascular disease risk. This meta-analysis aimed to systematically evaluate the effects of wolfberry-based randomized controlled trials (RCTs) on overall cardiovascular health. METHODS Four online databases (PubMed, CINAHL Plus, Medline and Cochrane Library) were searched to shortlist relevant RCTs. Outcomes of interests included blood lipids and lipoproteins, blood pressure, biomarkers of oxidative stress, inflammation and other cardiovascular health-related indicators. Random-effects models were used to provide a weighted mean difference (WMD) and/or Hedges' g for quantitative synthesis. This was coupled with subcategory analyses which stratified RCTs according to the form in which wolfberry was administered (whole wolfberry versus wolfberry extract). RESULTS From the 785 articles identified, 10 were selected for meta-analysis. Compared to the control, groups which consumed wolfberry showed a reduction in blood triglycerides [WMDpooled (95% confidence interval): - 0.14 (- 0.19, - 0.09) mmol/L] and increased blood high-density lipoprotein cholesterol [WMDpooled: 0.06 (0.02, 0.09) mmol/L]. Notably, effects for both triglycerides [WMDwhole: - 0.14 (- 0.19, - 0.09) mmol/L; WMDextract: - 0.07 (- 0.30, 0.16) mmol/L] and high-density lipoprotein cholesterol [WMDwhole: 0.06 (0.02, 0.09) mmol/L; WMDextract: 0.05 (- 0.02, 0.13) mmol/L] were more prominent after whole wolfberry interventions. Additionally, blood malondialdehyde equivalents were also significantly decreased in wolfberry consuming groups [Hedges' gpooled: - 1.45 (- 2.75, - 0.16)]. No changes were observed for the other lipids and lipoproteins as well as blood pressure. CONCLUSIONS Wolfberry consumption is effective in improving blood lipids and lipoproteins profile and lowering oxidative stress. This supports the incorporation of wolfberry, particularly as whole fruits, into dietary patterns targeted at improving cardiovascular health.

The impact of thermal processing on the simulated infant gastrointestinal digestion, bactericidal and anti-inflammatory activity of bovine lactoferrin - An in vitro study. Food Chem 2021; 362:130142.

Abstract
Lactoferrin (LF) is a multifunctional glycoprotein which, when thermally processed, undergoes significant physicochemical changes. The link between such changes and the bioactivity of LF is not well characterised and requires much research. In this work, bovine LF solutions (1%, w/v, protein, pH 7) were thermally processed using high temperature short time conditions (72, 80, 85 or 95 °C with 15 s holding times). Following this, it was shown that LF and heat induced LF aggregates were largely resistant to simulated infant gastric, but not intestinal, digestion. Also, the efficacy of LF bactericidal activity, and inhibition of lipopolysaccharide-induced NF-κB activation were negatively impacted by thermal processing. This study confirmed that the efficacy of LF bio-functionalities was affected by the extent of heat-induced changes in protein structure whereby processing conditions of least severity (i.e. pasteurisation) had the least impact on bioactivity.

Abstract
Incorporating zeaxanthin-rich wolfberry (Lycium barbarum) into a healthy dietary pattern may augment its antioxidant potential. The present 16-week, parallel design randomized controlled trial aimed to investigate the impact of adhering to a healthy dietary pattern, either with or without whole dried wolfberry (15 g/d) on oxidative stress status (plasma malondialdehyde and 8-iso-prostaglandin F2α) in middle-aged and older adults. Changes to carotenoids status (plasma and skin carotenoids) and body composition were further evaluated to explore potential mechanisms which underlie the antioxidant properties of wolfberry. Plasma 8-iso-prostaglandin F2α, plasma zeaxanthin and skin carotenoids status were significantly raised in the wolfberry consuming group (n = 22; p < 0.05) compared to the control group which showed no changes (n = 18). Likewise in the wolfberry group only, inverse association was observed between the change values of plasma zeaxanthin and plasma 8-iso-prostaglandin F2α (−0.21 (−0.43, 0.00) ng/µmol, regression coefficient (95% CI); p = 0.05). Wolfberry consumption with a healthy dietary pattern may serve as a dietary strategy to attenuate lipid peroxidation among middle-aged and older adults who are at a heightened risk of oxidative stress induced age-related disorders. The antioxidant properties of wolfberry may be attributed to its rich zeaxanthin content.

Abstract
Abstract
Introduction Inflammatory bowel disease (IBD) is characterized by a chronic inflammation of the gastrointestinal tract, without specific cause or pathogen.
Objective The effect of mesalazine in a colitis model induced by acetic acid (AA) was evaluated.
Methods We used 40 Wistar rats, ±350 g, divided into 4 groups: control (CO); control + mesalazine (CO + M); colitis (CL) and colitis + M (CL + M) at 24 and 48 h of treatment. The animals received the substances by an intracolonic enema of AA 4% and treatment with mesalazine PO 20 mg/kg after colitis induction.
Results Mesalazine reduced tissue damage in the gut, normalized sphincter anal pressure levels and decreased lipid peroxidation, metabolites of nitric oxide and iNOS and NF-kB expression in the treated groups in both treatment time points (24 and 48 h), as well as the activity of antioxidant enzymes.
Conclusion Mesalazine was effective in reducing tissue damage and oxidative and inflammatory damage, restored antioxidant capacity and increased anal sphincter pressure levels, possibly due to its antioxidant effect.

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
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
Ulcerative colitis is a common intestinal inflammatory disease characterized by upregulation of pro-inflammatory cytokines and oxidative stress. Zeaxanthin is a nutritional carotenoid that belongs to the xanthophyll family of pigments. It exerts potent anti-inflammatory and antioxidative effects. The present study aimed to evaluate the effect of zeaxanthin on acetic acid-induced ulcerative colitis in rats. Rats were randomly categorized into five groups: control, zeaxanthin, acetic acid, acetic acid + zeaxanthin, and acetic acid + prednisolone groups. Zeaxanthin (50 mg/kg/day) or prednisolone (5 mg/kg/day) was orally administered for 14 days before induction of ulcerative colitis. On the 15th day, colitis was induced by transrectal administration of 3% acetic acid. The rats were sacrificed 24 h after rectal instillation and their colon tissues were examined. Pretreatment with zeaxanthin significantly reduced disease activity index, wet colon weight, ulcer area, macroscopic scores, and histological changes. Zeaxanthin also effectively downregulated the levels of myeloperoxidase and malondialdehyde, upregulated the enzymatic activity of superoxide dismutase and catalase, and raised glutathione levels. With regard to anti-inflammatory mechanisms, zeaxanthin suppressed tumor necrosis factor-alpha, interferon-gamma, interleukin-6, interleukin-1 beta, and nuclear transcription factor kappa B levels, and inhibited nitric oxide synthase and cyclooxygenase-2 protein expression. Our results indicate that oral administration of zeaxanthin ameliorates acetic acid-induced colitis in rats via antioxidative effects and modulation of pro-inflammatory cytokine and mediator activity. Therefore, zeaxanthin may be an effective therapeutic candidate for the treatment of ulcerative colitis.

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
BACKGROUND Mouse models of inflammatory bowel disease (IBD) identify an impact on the enteric nervous system (ENS) but do not distinguish between Crohn's disease and ulcerative colitis phenotypes. In these models, analgesia is required, but its influence on different strains and disease outcomes is unknown. Therefore, changes to the ENS and intestinal smooth muscle were studied in trinitrobenzene sulfonic acid (TNBS) and dextran sodium sulfate (DSS) induced colitis to identify the effects of analgesia, and compared between two mouse strains. METHODS Colitis was induced in CD1 or BALB/c mice receiving analgesia with either buprenorphine or tramadol. Euthanasia was on Day 8 (DSS) or Day 4 (TNBS). Outcomes were Disease Activity Index and cytokine assay, and quantitative histology and immunocytochemistry were used to evaluate effects of inflammation on neurons and smooth muscle. KEY RESULTS In BALB/c mice, both models of colitis caused >2-fold increase in smooth muscle cell number. DSS caused axon proliferation without neuron loss while TNBS caused significant neuron loss and axonal damage. Buprenorphine (but not tramadol) was generally anti-inflammatory in both strains, but correlated with lethal outcomes to TNBS in BALB/c mice. CONCLUSIONS AND INFERENCES Smooth muscle growth is common to both models of colitis. In contrast, ENS damage in TNBS is correlated with the severe response of a Crohn's disease-like phenotype, while DSS correlates with a milder, ulcerative colitis-like outcome in the deeper tissues. Analgesia with tramadol over buprenorphine is supported for mouse studies of IBD.

Abstract
Goji berry (Lycium barbarum) exerts immune modulation and suppresses inflammation in vitro and in vivo. We hypothesized that Goji berry had beneficial effects on dextran sulfate sodium (DSS)-induced colitis in C57BL/6 mice through suppressing inflammation. Six-week-old male C57BL/6 mice were supplemented with a standard AIN-93G diet with or without 1% (w/w) Goji berry for 4 weeks. Then, colitis was induced by supplementing 3% DSS in drinking water for 7 days, followed by 7 days of remission period to mimic ulcerative colitis symptoms. Goji berry supplementation ameliorated DSS-induced body weight loss, diminished diarrhea and gross bleeding, and resulted in a significantly decreased disease activity index, as well as DSS-associated colon shortening. Moreover, 30% mortality rate caused by DSS-induced colitis was avoided because of Goji berry supplementation. Histologically, Goji berry ameliorated colonic edema, mucosal damage and neutrophil infiltration into colonic intestinal tissue in response to DSS challenge, which was associated with decreased expression of chemokine (C-X-C motif) ligand 1 and monocyte chemoattractant protein-1, as well as inflammatory mediators interleukin-6 and cyclooxygenase-2. In conclusion, Goji supplementation confers protective effects against DSS-induced colitis, which is associated with decreased neutrophil infiltration and suppressed inflammation. Thus, dietary Goji is likely beneficial to inflammatory bowel disease patients as a complementary therapeutic strategy.

Abstract
Ulcerative colitis and Crohn's disease are the 2 major phenotypes of inflammatory bowel disease (IBD), which are influenced by a complex interplay of immunological and genetic elements, though the precise etiology still remains unknown. With IBD developing into a globally prevailing disease, there is a need to explore new targets and a thorough understanding of the pathophysiological differences between the healthy and diseased gut could unearth new therapeutic opportunities. In this review, we provide an overview of the major aspects of IBD pathogenesis and thereafter present a comprehensive analysis of the gut pathophysiology leading to a discussion on some of the most promising targets and biologic therapies currently being explored. These include various gut proteins (CXCL-10, GATA-3, NKG2D, CD98, microRNAs), immune cells recruited to the gut (mast cells, eosinophils, toll-like receptors 2, 4), dysregulated proinflammatory cytokines (interleukin-6, -13, -18, -21), and commensal microbiota (probiotics and fecal microbiota transplantation). We also evaluate some of the emerging nonconventional therapies being explored in IBD treatment focusing on the latest developments in stem cell research, oral targeting of the gut-associated lymphoid tissue, novel anti-inflammatory signaling pathway targeting, adenosine deaminase inhibition, and the beneficial effects of antioxidant and nutraceutical therapies. In addition, we highlight the growth of biologics and their targets in IBD by providing information on the preclinical and clinical development of over 60 biopharmaceuticals representing the state of the art in ulcerative colitis and Crohn's disease drug development.

Antioxidant therapy for treatment of inflammatory bowel disease: Does it work? Redox Biol 2015; 6:617-639.

Abstract
Oxidative stress (OS) is considered as one of the etiologic factors involved in several signals and symptoms of inflammatory bowel diseases (IBD) that include diarrhea, toxic megacolon and abdominal pain. This systematic review discusses approaches, challenges and perspectives into the use of nontraditional antioxidant therapy on IBD, including natural and synthetic compounds in both human and animal models. One hundred and thirty four papers were identified, of which only four were evaluated in humans. Some of the challenges identified in this review can shed light on this fact: lack of standardization of OS biomarkers, absence of safety data and clinical trials for the chemicals and biological molecules, as well as the fact that most of the compounds were not repeatedly tested in several situations, including acute and chronic colitis. This review hopes to stimulate researchers to become more involved in this fruitful area, to warrant investigation of novel, alternative and efficacious antioxidant-based therapies. Major biomarkers used for evaluation of antioxidant therapy were MPO, TBARS/MDA and glutathione levels. Challenges were identified for the yet poor use of antioxidant therapy in IBD. This review stimulates the investigation of alternative and efficacious antioxidant therapies.
