Abstract
Excessive body weight is associated with many chronic metabolic diseases and weight loss, so far, remains the gold standard treatment. However, despite tremendous efforts exploring optimal treatments for obesity, many individuals find losing weight and maintaining a healthy body weight difficult. Weight loss is often not sustainable resulting in weight regain and subsequent efforts to lose weight. This cyclic pattern of weight loss and regain is termed "yoyo dieting" and predisposes individuals to obesity and metabolic comorbidities. How yoyo dieting might worsen obesity complications during the weight recurrence phase remains unclear. In particular, there is limited data on the role of the gut microbiome in yoyo dieting. Gut health distress, especially gut inflammation and microbiome perturbation, is strongly associated with metabolic dysfunction and disturbance of energy homeostasis in obesity. In this review, we summarise current evidence of the crosstalk between the gastrointestinal system and energy balance, and the effects of yoyo dieting on gut inflammation and gut microbiota reshaping. Finally, we focus on the potential effects of post-dieting weight loss in improving gut health and identify current knowledge gaps within the field, including gut-derived peptide hormones and their potential suitability as targets to combat weight regain, and how yoyo dieting and associated changes in the microbiome affect the gut barrier and the enteric nervous system, which largely remain to be determined.

Abstract
Colorectal cancer (CRC) is a major cause of cancer-related deaths worldwide, underscoring the importance of understanding the diverse molecular and genetic underpinnings of CRC to improve its diagnosis, prognosis, and treatment. This review delves into the adenoma-carcinoma-metastasis model, emphasizing the "APC-KRAS-TP53" signature events in CRC development. CRC is categorized into four consensus molecular subtypes, each characterized by unique genetic alterations and responses to therapy, illustrating its complexity and heterogeneity. Furthermore, we explore the role of chronic inflammation and the gut microbiome in CRC progression, emphasizing the potential of targeting these factors for prevention and treatment. This review discusses the impact of dietary carcinogens and lifestyle factors and the critical role of early detection in improving outcomes, and also examines conventional chemotherapy options for CRC and associated challenges. There is significant focus on the therapeutic potential of flavonoids for CRC management, discussing various types of flavonoids, their sources, and mechanisms of action, including their antioxidant properties, modulation of cell signaling pathways, and effects on cell cycle and apoptosis. This article presents evidence of the synergistic effects of flavonoids with conventional cancer therapies and their role in modulating the gut microbiome and immune response, thereby offering new avenues for CRC treatment. We conclude by emphasizing the importance of a multidisciplinary approach to CRC research and treatment, incorporating insights from genetic, molecular, and lifestyle factors. Further research is needed on the preventive and therapeutic potential of natural compounds, such as flavonoids, in CRC, underscoring the need for personalized and targeted treatment strategies.

Abstract
Colorectal cancer (CRC) is currently the third leading cancer and commonly develops from chronic intestinal inflammation. A strong association was found between gut microbiota and intestinal inflammation and carcinogenic risk. Flavonoids, which are abundant in vegetables and fruits, can inhibit inflammation, regulate gut microbiota, protect gut barrier integrity, and modulate immune cell function, thereby attenuating colitis and preventing carcinogenesis. Upon digestion, about 90% of flavonoids are transported to the colon without being absorbed in the small intestine. This phenomenon increases the abundance of beneficial bacteria and enhances the production of short-chain fatty acids. The gut microbe further metabolizes these flavonoids. Interestingly, some metabolites of flavonoids play crucial roles in anti-inflammation and anti-tumor effects. This review summarizes the modulatory effect of flavonoids on gut microbiota and their metabolism by intestinal microbe under disease conditions, including inflammatory bowel disease, colitis-associated cancer (CAC), and CRC. We focus on dietary flavonoids and microbial interactions in intestinal mucosal barriers as well as intestinal immune cells. Results provide novel insights to better understand the crosstalk between dietary flavonoids and gut microbiota and support the standpoint that dietary flavonoids prevent intestinal inflammation and carcinogenesis.

Abstract
Anemonopsis Siebold et Zucc. is an unstudied single-species genus belonging to the tribe Cimicifugeae (Ranunculaceae). The only species of this genus-Anemonopsis macrophylla Siebold and Zucc.-is endemic to Japan. There are no data on its chemical composition. This work is the first to determine (with liquid chromatography-high-resolution mass spectrometry, LC-HRMS) the chemical composition of methanol extracts of leaves and flowers of A. macrophylla. More than 100 compounds were identified. In this plant, the classes of substances are coumarins (13 compounds), furocoumarins (3), furochromones (2), phenolic acids (21), flavonoids (27), and fatty acids and their derivatives (15 compounds). Isoferulic acid (detected in extracts from this plant) brings this species closer to plants of the genus Cimicifuga, one of the few genera containing this acid and ferulic acid at the same time. Isoferulic acid is regarded as a reference component of a quality indicator of Cimicifuga raw materials. The determined profiles of substances are identical between the leaf and flower methanol extracts. Differences in levels of some identified substances were revealed between the leaf and flower extracts of A. macrophylla; these differences may have a substantial impact on the manifestation of the biological and pharmacological effects of the extracts in question.

Circadian Rhythm Perturbation Aggravates Gut Microbiota Dysbiosis in Dextran Sulfate Sodium-Induced Colitis in Mice. Nutrients 2024; 16:247. [PMID: 38257139 PMCID: PMC10819604 DOI: 10.3390/nu16020247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/09/2024] [Accepted: 01/10/2024] [Indexed: 01/24/2024] Open
Abstract
Circadian rhythm disruption is increasingly considered an environmental risk factor for the development and exacerbation of inflammatory bowel disease. We have reported in a previous study that nychthemeral dysregulation is associated with an increase in intestinal barrier permeability and inflammation in mice with dextran sulfate sodium (DSS)-induced colitis. To investigate the effect of circadian rhythm disruption on the composition and diversity of the gut microbiota (GM), sixty male C57BL/6J mice were initially divided to two groups, with the shifted group (n = 30) exposed to circadian shifts for three months and the non-shifted group (n = 30) kept under a normal light-dark cycle. The mice of the shifted group were cyclically housed for five days under the normal 12:12 h light-dark cycle, followed by another five days under a reversed light-dark cycle. At the end of the three months, a colitis was induced by 2% DSS given in the drinking water of 30 mice. Animals were then divided into four groups (n = 15 per group): sham group non-shifted (Sham-NS), sham group shifted (Sham-S), DSS non-shifted (DSS-NS) and DSS shifted (DSS-S). Fecal samples were collected from rectal content to investigate changes in GM composition via DNA extraction, followed by high-throughput sequencing of the bacterial 16S rRNA gene. The mouse GM was dominated by three phyla: Firmicutes, Bacteroidetes and Actinobacteria. The Firmicutes/Bacteroidetes ratio decreased in mice with induced colitis. The richness and diversity of the GM were reduced in the colitis group, especially in the group with inverted circadian rhythm. Moreover, the GM composition was modified in the inverted circadian rhythm group, with an increase in Alloprevotella, Turicibacter, Bacteroides and Streptococcus genera. Circadian rhythm inversion exacerbates GM dysbiosis to a less rich and diversified extent in a DSS-induced colitis model. These findings show possible interplay between circadian rhythm disruption, GM dynamics and colitis pathogenesis.

Abstract
Bacterial infection, which is still one of the leading causes of death in humans, poses an enormous threat to the worldwide public health system. Antibiotics are the primary medications used to treat bacterial diseases. Currently, the discovery of antibiotics has reached an impasse, and due to the abuse of antibiotics resulting in bacterial antibiotic resistance, researchers have a critical desire to develop new antibacterial agents in order to combat the deteriorating antibacterial situation. Natural chalcones, the flavonoids consisting of two phenolic rings and a three-carbon α, β-unsaturated carbonyl system, possess a variety of biological and pharmacological properties, including anti-cancer, anti-inflammatory, antibacterial, and so on. Due to their potent antibacterial properties, natural chalcones possess the potential to become a new treatment for infectious diseases that circumvents existing antibiotic resistance. Currently, the majority of research on natural chalcones focuses on their synthesis, biological and pharmacological activities, etc. A few studies have been conducted on their antibacterial activity and mechanism. Therefore, this review focuses on the antibacterial activity and mechanisms of seventeen natural chalcones. Firstly, seventeen natural chalcones have been classified based on differences in antibacterial mechanisms. Secondly, a summary of the isolation and biological activity of seventeen natural chalcones was provided, with a focus on their antibacterial activity. Thirdly, the antibacterial mechanisms of natural chalcones were summarized, including those that act on bacterial cell membranes, biological macromolecules, biofilms, and quorum sensing systems. This review aims to lay the groundwork for the discovery of novel antibacterial agents based on chalcones.

Abstract
The composition, viability and metabolic functionality of intestinal microbiota play an important role in human health and disease. Studies on intestinal microbiota are often based on fecal samples, because these can be sampled in a non-invasive way, although procedures for sampling, processing and storage vary. This review presents factors to consider when developing an automated protocol for sampling, processing and storing fecal samples: donor inclusion criteria, urine-feces separation in smart toilets, homogenization, aliquoting, usage or type of buffer to dissolve and store fecal material, temperature and time for processing and storage and quality control. The lack of standardization and low-throughput of state-of-the-art fecal collection procedures promote a more automated protocol. Based on this review, an automated protocol is proposed. Fecal samples should be collected and immediately processed under anaerobic conditions at either room temperature (RT) for a maximum of 4 h or at 4 °C for no more than 24 h. Upon homogenization, preferably in the absence of added solvent to allow addition of a buffer of choice at a later stage, aliquots obtained should be stored at either -20 °C for up to a few months or -80 °C for a longer period-up to 2 years. Protocols for quality control should characterize microbial composition and viability as well as metabolic functionality.

Abstract
It is well-established that there are trillions of gut microbiota (GM) in the human gut. GM and its metabolites can reportedly cause cancer by causing abnormal immune responses. With the development of sequencing technology and the application of germ-free models in recent years, significant inroads have been achieved in research on GM and microbiota-related metabolites. Accordingly, the role and mechanism of GM in colorectal cancer (CRC) development have been gradually revealed. Traditional Chinese medicine (TCM) represents an important source of natural medicines and herbal products, with huge potential as anti-CRC agents. The potential application of TCM to target gut microbes for the treatment of colorectal cancer represents an exciting area of investigation.

Abstract
Malignant tumors remain one of the main sources of morbidity and mortality around the world. A chemotherapeutic approach to cancer treatment poses a multitude of challenges, primarily due to the low selectivity and genotoxicity of the majority of chemotherapeutic drugs currently used in the clinical practice, often leading to treatment-induced tumors formation. Highly selective antitumor drugs can largely resolve this issue, but their high selectivity leads to significant drawbacks due to the intrinsic tumor heterogeneity. In contrast, plant polyphenols can simultaneously affect many processes that are involved in the acquiring and maintaining of hallmark properties of malignant cells, and their toxic dose is typically much higher than the therapeutic one. In the present work we describe the mechanisms of the action of polyphenols on cancer cells, including their effects on genetic and epigenetic instability, tumor-promoting inflammation, and altered microbiota.

The current treatment including surgery, chemotherapy or radiotherapy has several limitations such as drug toxicity, cancer recurrence or drug resistance and thus it is a great challenge to discover an effective and safe therapy for CRC and GC. In the last decade, numerous phytochemicals and their synthetic analogs have attracted attention due to their anticancer effect and low organ toxicity. Chalcones, plant-derived polyphenols, received marked attention due to their biological activities as well as for relatively easy structural manipulation and synthesis of new chalcone derivatives. In this study, we discuss the mechanisms by which chalcones in both in vitro and in vivo conditions suppress cancer cell proliferation or cancer formation.

Kong S, Li P, Verpoorte R, Li M, Dai Y. Chemical and pharmacological difference between honey-fried licorice and fried licorice. JOURNAL OF ETHNOPHARMACOLOGY 2023; 302:115841. [PMID: 36270557 DOI: 10.1016/j.jep.2022.115841] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 10/04/2022] [Accepted: 10/12/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE According to textual research of books from ancient times till now, there are three main preparation methods of "fried licorice", including frying licorice without excipients (F), frying licorice after dipping with water (W), and frying licorice with honey (H). However, with the development over many successive generations, honey frying has gradually become the main processing form of licorice, whereas the fried licorice is nowadays rarely used. AIM OF THE STUDY The objectives of this study were to clarify the differences of the three forms of "fried licorice" in chemical composition and pharmacological activities, and to screen quality markers for differently processed licorice. It is expected to provide a scientific basis for the rational choice of "fried licorice" as medicine. MATERIALS AND METHODS Non-target metabolomic analysis based on UHPLC-QE-Orbitrap-MS was conducted to compare the chemical differences between the differently processed licorice material. Pharmacodynamically, the differences in immunomodulatory activity (including intestinal flora experiment), anti-inflammatory activity, and hepatoprotective activity of the differently processed licorice were evaluated. Furthermore, multivariate statistical analysis was performed to screen potential quality markers of honey-fried licorice. The serum concentration of selected markers was determined by UHPLC-QqQ-MS. RESULTS Metabolomic analysis showed no difference in the chemical composition of F and W, whereas the chemical composition of H was significantly different from that of F and R. The immunomodulatory activity, anti-acute inflammatory effect, and hepatoprotective effect of licorice were significantly improved after frying with honey; No significant differences were observed between F and H in term of immunomodulatory activity and anti-acute inflammatory effect, whereas, H is better than F in terms of liver-protective activity. The intestinal flora experiment confirmed that H does have immunomodulatory activity, while F may induce an increased abundance of certain pathogenic bacteria in the intestine. Multivariate statistical analysis suggests that the content of liquiritin (2), liquiritigenin (3), isoliquiritin (5), isoliquiritigenin (6) and glycyrrhizic acid (7) plusing glycyrrhetinic acid (8) in H group is closely correlated with its improved effects. CONCLUSIONS This study provides a scientific rational for the selection of "fried licorice" processing methods. In addition, it provides a scientific basis for the selection of quality markers of differently processed licorice.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide and the second leading cause of cancer-related death. In recent years, the relationship between gut microbiota and CRC has attracted increasing attention from researchers. Studies reported that changes in the composition of gut microbiota, such as increase in the number of Fusobacterium nucleatum and Helicobacter hepaticus, impair the immune surveillance by affecting the intestinal mucosal immunity and increase the risk of tumor initiation and progression. The tumor microenvironment is the soil for tumor survival. Close contacts between gut microbiota and the tumor microenvironment may directly affect the progression of tumors and efficacy of antitumor drugs, thus influencing the prognosis of patients with CRC. Recently, many studies have shown that traditional Chinese medicine can safely and effectively improve the efficacy of antitumor drugs, potentially through remodeling of the tumor microenvironment by regulated gut microbiota. This article describes the effect of gut microbiota on the tumor microenvironment and possible mechanisms concerning the initiation and progression of CRC, and summarizes the potential role of traditional Chinese medicine.

Long-term environmental levels of microcystin-LR exposure induces colorectal chronic inflammation, fibrosis and barrier disruption via CSF1R/Rap1b signaling pathway. JOURNAL OF HAZARDOUS MATERIALS 2022; 440:129793.

Abstract
Microcystin-LR (MC-LR) is a very common toxic cyanotoxins threating ecosystems and the public health. This study aims to explore the long-term effects and potential toxicity mechanisms of MC-LR exposure at environmental levels on colorectal injury. We performed histopathological, biochemical indicator and multi-omics analyses in mice with low-dose MC-LR exposure for 12 months. Long-term environmental levels of MC-LR exposure caused epithelial barrier disruption, inflammatory cell infiltration and an increase of collagen fibers in mouse colorectum. Integrated proteotranscriptomics revealed differential expression of genes/proteins, including CSF1R, which were mainly involved in oxidative stress-induced premature senescence and inflammatory response. MC-LR induced chronic inflammation and fibrosis through oxidative stress and CSF1R/Rap1b signaling pathway were confirmed in cell models. We found for the first time that long-term environmental levels of MC-LR exposure caused colorectal chronic inflammation, fibrosis and barrier disruption via a novel CSF1R/Rap1b signaling pathway. Moreover, MC-LR changed the gut microbiota and microbial-related metabolites in a vicious cycle aggravating colorectal injury. These findings provide novel insights into the effects and toxic mechanisms of MC-LR and suggest strategies for the prevention and treatment of MC-caused intestinal diseases.

Network analysis and experimental pharmacology study explore the protective effects of Isoliquiritigenin on 5-fluorouracil-Induced intestinal mucositis. Front Pharmacol 2022; 13:1014160. [PMID: 36278232 PMCID: PMC9582754 DOI: 10.3389/fphar.2022.1014160] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 09/20/2022] [Indexed: 11/21/2022] Open
Abstract
5-fluorouracil (5-FU) is one of the most widely used chemotherapy drugs for malignant tumors. However, intestinal mucositis caused by 5-FU is a severe dose-limiting toxic effect and even leads to treatment interruption. Isoliquiritigenin (ISL) is one of the main active compounds of licorice, which is a traditional Chinese herbal medicine commonly used in inflammation and gastrointestinal diseases. It is speculated that ISL have protective effects on intestinal mucositis. However, no such studies have been reported. Therefore, to investigate the impact of ISL on 5-Fu-induced intestinal mucositis, a strategy based on network prediction and pharmacological experimental validation was proposed in this study. Firstly, the targets and mechanism of ISL in alleviating 5-Fu-induced gastrointestinal toxicity were predicted by network analysis. And the results were further confirmed by molecular docking. Then, a mouse model of intestinal mucositis was established by intraperitoneal injection of 5-FU (384 μmol/kg) to verify the prediction of network analysis. The network analysis results suggested that PTGS2 (Prostaglandin G/H synthase 2) and NOS2 (Nitric oxide synthase, inducible) might be the critical targets of ISL for reducing the intestinal toxicity of 5-FU. In addition, KEGG and GO enrichment analysis revealed that the HIF-1, TNF, MAPK, IL-17, PI3K-Akt, Ras, NF-kappa B signaling pathway, and biological processes of the inflammatory response, apoptosis regulation, NO production and NF-kappa B transcription factor activity might be involved in the mechanism of ISL against intestinal mucositis. Subsequent animal experiments showed that ISL could reduce the weight loss, leukopenia and mucosal damage caused by 5-FU. Compared with the intestinal mucositis model, the protein expressions of PTGS2, NOS2, TNFα (Tumor necrosis factor-alpha) and NF-κB p65 (nuclear factor kappa-B P65) were decreased after ISL treatment. In conclusion, this study is the fist time to find that ISL can attenuate 5-FU-induced intestinal mucositis in mice. Its anti-mucositis effect may be through regulating TNF/NF-κB pathway and inhibiting inflammatory mediators PTGS2 and NOS2. It will provide a potential candidate for the prevention and treatment of chemotherapy-induced intestinal mucositis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Licorice, as a traditional Chinese herbal medicine, possessing the efficacies of invigorating spleen and replenishing qi, heat-clearing and detoxicating, phlegm-resolving and cough suppressant, relieving spasm and pain, and hamonizing actions of various medicines. AIM OF THE STUDY The goal of this systematic review, which includes meta-analysis and network pharmacology in preclinical studies, is to investigate the multiple efficacies of licorice on ulcerative colitis (UC). MATERIALS AND METHODS We searched several databases, e.g., Web of Science, Elsevier ScienceDirect and PubMed until Januanry 2022 for literature collection, and the Review Manager 5.3 was used to analyze the data. To synthesize the retrieved data, the fixed and random-effects models were utilized, respectively, and network pharmacology was applied to confirm the mechanisms. RESULTS Based on the result of meta-analysis, it suggested that the treatments of licorice extract and its active compounds showed strong therpeutic effects, which not only reflected the declining histological score, a index of the colitis severity [SMD = -2.86, 95% CI (-3.65, -2.08); P < 0.00001], but also reversed colonic shortness [WMD = 1.67, 95% CI (1.16, 2.19); P < 0.00001] between experimental UC model and licorice-treatment groups. In addition, it suggested the significant reduction of TNF-α level [SMD = -2.70, 95% CI (-3.23, -2.16); P < 0.00001], which acted as a crucial role in inflammatory response. Furthermore, from the results of network pharmacology, it indicated that anti-inflammation, anti-oxidative stress, immunomodulatory effect and microbiota homeostasis were the predominant therapeutic mechanisms of licorice extract and its active compounds treating UC. CONCLUSION This systematic review with meta-analysis and network pharmacology demonstrates an efficient role of licorice extract and its active compounds in preclinical studies of UC, which provides supporting evidence for clinical trial implementation. However, there exist some limitations, such as technique quality decificency, missed reports due to negative outcome, failure to calculate sample size, and the risk of bias.

Abstract
Although a natural anti-inflammatory ingredient, isoliquiritigenin (ISL), plays an effective role in ulcerative colitis (UC) treatment, a series of drawbacks still limit its clinical application, including the poor solubility, instability in gastrointestinal tract, and rapid elimination rate of ISL. Zein-based NPs display the benefits on drug loading and delivery, whereas with the poor stability. In this study, an edible nano-system composed by zein/caseinate complex was fabricated for the colon-targeting delivery of ISL, to improve its colon retention and anti-UC effects. The optimized ISL loaded zein/caseinate NPs (ISL@NPs) were prepared by single-factor design by anti-solvent precipitation method, and then characterized. The improved cellular uptake of ISL@NPs on NCM460 and RAW 264.7 cells was evaluated in vitro. The colon tissue permeability and retention capacity in vivo, and the anti-UC efficacy of ISL@NPs in DSS-induce UC were implemented. As a result, ISL@NPs with the high drug loading efficiency of 9.39% ± 0.26%, the average particle diameter of 137.32 ± 2.54 nm, exhibited the pH-sensitive stability in the different simulated gastrointestinal buffer. Compared with free ISL, ISL@NPs showed significantly higher cellular uptake ability in NCM460 and RAW 264.7 cells. Based on in vivo imaging system, zein/caseinate NPs showed the prolonged colonic retention and the enhanced penetration into the colonic epithelium. Finally, the oral administration of ISL@NPs could effectively alleviate the UC-related symptoms, down-regulate the production of pro-inflammatory factors, and reduce the infiltration of macrophages and neutrophils in colon tissues. In this study, an oral colon-specific nano-system, composed with the natural compound and edible materials, was developed as the promising alternatives in the prevention and treatment of UC.

[PMID: 36087619 DOI: 10.1016/j.fct.2022.113368] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 08/05/2022] [Accepted: 08/10/2022] [Indexed: 11/28/2022]
Abstract
Silver (nAg) and titanium dioxide (nTiO2) nanoparticles improve texture, flavour or anti-microbial properties of various food products and packaging materials. Despite their increased oral exposure, their potential toxicities in the dysfunctional intestine are unclear. Here, the effects of ingested nAg or nTiO2 on inflamed colon were revealed in a mouse model of chemical-induced acute ulcerative colitis. Mice (eight/group) were exposed to nAg or nTiO2 by oral gavage for 10 consecutive days. We characterized disease phenotypes, histology, and alterations in colonic transcriptome (RNA sequencing) and gut microbiome (16S sequencing). Oral exposure to nAg caused only minor changes in phenotypic hallmarks of colitic mice but induced extensive responses in gene expression enriching processes of apoptotic cell death and RNA metabolism. Instead, ingested nTiO2 yielded shorter colon, aggravated epithelial hyperplasia and deeper infiltration of inflammatory cells. Both nanoparticles significantly changed the gut microbiota composition, resulting in loss of diversity and increase of potential pathobionts. They also increased colonic mucus and abundance of Akkermansia muciniphila. Overall, nAg and nTiO2 induce dissimilar immunotoxicological changes at the molecular and microbiome level in the context of colon inflammation. The results provide valuable information for evaluation of utilizing metallic nanoparticles in food products for the vulnerable population.

[PMID: 35961465 DOI: 10.1016/j.jnutbio.2022.109124] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2021] [Revised: 07/09/2022] [Accepted: 07/14/2022] [Indexed: 12/18/2022]
Abstract
Polyphenols are known to interact with gut microbes that play key roles in maintaining gut health, but the role of gut microbiota modulation by polyphenols in mitigating colonic diseases is not fully established. We hypothesize that the interaction of polyphenols with the gut microbiota contributes to the attenuation of colitis and colitis-associated colon cancer (CAC). To test this hypothesis, we examined the effects of dietary supplementation of polyphenol-rich grape powder (GP) on azoxymethane (AOM) and dextran sulfate sodium (DSS)-induced colitis, CAC and the gut microbiota in mice (study 1), and further compared anti-colitis effects of GP in regular and antibiotic-treated mice (study 2). Compared to the control diet that has matched non-polyphenol contents, 10% GP, but not 3% GP, attenuated AOM-DSS induced colitis and tumor multiplicity by 29% (p<0.05). Ten percent GP increased gut bacterial evenness and counteracted CAC-induced decrease of bacterial evenness and changes of microbial composition. Remarkably, gut bacterial functional profiles of healthy mice and diseased mice fed 10% GP were similar, and both were significantly different from those of diseased mice with the control diet. Furthermore, 10% GP increased the relative abundance of butyrate-producing bacteria in the Lachnospiraceae family and enhanced the concentrations of fecal butyrate. Additionally, 10% GP mitigated DSS-induced colitis in conventional mice, but not the antibiotic-treated, gut microbe-depleted mice. Collectively, our studies demonstrate that grape polyphenols alleviate colonic diseases and prevent disease-associated dysbiosis, and their interaction with the gut microbiota may play a causative role in the protection of gut health.

Abstract
Colorectal cancer (CRC) is the third most frequent malignancy and the second cause of cancer death worldwide. Several factors have been postulated to be involved in CRC pathophysiology, including physical inactivity, unhealthy dietary habits, obesity, and the gut microbiota. Emerging data suggest that the microbiome may play a key role in CRC prognosis and derived complications in patients undergoing colorectal surgery. On the other hand, dietary intervention has been demonstrated to be able to induce significant changes in the gut microbiota and related metabolites in different conditions; therefore, the manipulation of gut microbiota through dietary intervention may constitute a useful approach to improve perioperative dysbiosis and post-surgical outcomes in patients with CRC. In this article, we review the role of the gut microbiota in CRC surgery complications and the potential therapeutic modulation of gut microbiome through nutritional intervention in patients with CRC undergoing surgery.

Chemically Induced Colitis-Associated Cancer Models in Rodents for Pharmacological Modulation: A Systematic Review. J Clin Med 2022; 11:jcm11102739. [PMID: 35628865 PMCID: PMC9146029 DOI: 10.3390/jcm11102739] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 04/29/2022] [Accepted: 05/10/2022] [Indexed: 02/01/2023] Open
Abstract
Animal models for colitis-associated colorectal cancer (CACC) represent an important tool to explore the mechanistic basis of cancer-related inflammation, providing important evidence that several inflammatory mediators play specific roles in the initiation and perpetuation of colitis and CACC. Although several original articles have been published describing the CACC model in rodents, there is no consensus about the induction method. This review aims to identify, summarize, compare, and discuss the chemical methods for the induction of CACC through the PRISMA methodology. METHODS We searched MEDLINE via the Pubmed platform for studies published through March 2021, using a highly sensitive search expression. The inclusion criteria were only original articles, articles where a chemically-induced animal model of CACC is described, preclinical studies in vivo with rodents, and articles published in English. RESULTS Chemically inducible models typically begin with the administration of a carcinogenic compound (as azoxymethane (AOM) or 1,2-dimethylhydrazine (DMH)), and inflammation is caused by repeated cycles of colitis-inducing agents (such as 2,4,6-trinitrobenzenesulfonic acid (TNBS) or dextran sulfate sodium (DSS)). The strains mostly used are C57BL/6 and Balb/c with 5-6 weeks. To characterize the preclinical model, the parameters more used include body weight, stool consistency and morbidity, inflammatory biomarkers such as tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-1β, angiogenesis markers such as proliferating cell nuclear antigen (PCNA), marker of proliferation Ki-67, and caspase 3, the presence of ulcers, thickness or hyperemia in the colon, and histological evaluation of inflammation. CONCLUSION The AOM administration seems to be important to the CACC induction method, since the carcinogenic effect is achieved with just one administration. DSS has been the more used inflammatory agent; however, the TNBS contribution should be more studied, since it allows a reliable, robust, and a highly reproducible animal model of intestinal inflammation.

Pre-Administration of Berberine Exerts Chemopreventive Effects in AOM/DSS-Induced Colitis-Associated Carcinogenesis Mice via Modulating Inflammation and Intestinal Microbiota. Nutrients 2022; 14:nu14040726.

Abstract
Inflammatory activation and intestinal flora imbalance play an essential role in the development and progression of colorectal cancer (CRC). Berberine (BBR) has attracted great attention in recent years due to its heath-related benefits in inflammatory disorders and tumors, but the intricate mechanisms have not been fully elucidated. In this study, the effects and the mechanism of BBR on colon cancer were investigated in an azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced colitis-associated carcinogenesis mice model. Our results showed that pre-administration of BBR showed a decrease in weight loss, disease activity index (DAI) score, and the number of colon tumors in mice, compared with the model group. The evidence from pathological examination indicated that the malignancy of intestinal tumors was ameliorated after pre-administration of BBR. Additionally, pre-administration with BBR suppressed the expression of pro-inflammatory factors (interleukin (IL)-6, IL-1β, cyclooxygenase (COX)-2 and tumor necrosis factor (TNF)-α) and the cell-proliferation marker Ki67, while expression of the tight junction proteins (ZO-1 and occludin) were increased in colon tissue. Moreover, the levels of critical pathway proteins involved in the inflammatory process (p-STAT3 and p-JNK) and cell cycle regulation molecules (β-catenin, c-Myc and CylinD1) exhibited lower expression levels. Besides, 16S rRNA sequence analysis indicated that pre-administration of BBR increased the ratio of Firmicutes/Bacteroidetes (F:M) and the relative abundance of potentially beneficial bacteria, while the abundance of cancer-related bacteria was decreased. Gavage with Lactobacillus rhamnosus can improve the anti-tumor effect of BBR. Overall, pre-administration of BBR exerts preventive effects in colon carcinogenesis, and the mechanisms underlying these effects are correlated with the inhibition of inflammation and tumor proliferation and the maintenance of intestinal homeostasis.

Abstract
SCOPE Epidemiological studies show a consistent and compelling association between the risk of colorectal cancer development and obesity, but its mechanisms remain poorly understood. Evidence is mounting that colorectal cancer can be prevented by nutritional supplements, such as phytochemicals. Garcinol, a polyisoprenylated benzophenone derivative, is widely present in Garcinia plants. This study investigates the potential role of garcinol supplementation in ameliorating obesity-induced colon cancer development. METHODS AND RESULTS An animal model to investigate the effect of high-fat-diet (HFD)-induced obesity on promoting colitis-associated colon cancer (AOM (azoxymethane)/DSS (dextran sodium sulfate)-induced) is designed. The results show that HFD can promote colitis-associated colon cancer as compared to an AOM/DSS group without the intervention of obesity, and supplementing with 0.05% garcinol in the diet can significantly ameliorate obesity-promoted colon carcinogenesis. The results also reveals that the microbiota composition of each group is significantly different and clustered. The most representative genera are Alistipes, Romboutsia, and Ruminococcus. The RNA-sequencing results show that the administration of garcinol can regulate genes and improve obesity-promoting colitis-associated colon carcinogenesis. CONCLUSION The study results suggest that garcinol can prevent obesity-promoted colorectal cancer, and these findings provide important niches for the future development of garcinol as functional foods or adjuvant therapeutic agents.

Jinmaitong ameliorates diabetic peripheral neuropathy in streptozotocin-induced diabetic rats by modulating gut microbiota and neuregulin 1. Aging (Albany NY) 2021; 12:17436-17458.

Abstract
Jinmaitong (JMT), a compound prescription of traditional Chinese medicine, has long been used as a therapy for diabetic peripheral neuropathy (DPN). However, the neuroprotective mechanisms of JMT and its effect on gut microbiota remained unknown. Here, we examined the effects of JMT on behavior, pathomorphology and gut microbiota in streptozotocin (STZ)-induced DPN rats. Compared to distilled water administration, JMT reversed decreases in mechanical withdraw threshold and intraepidermal nerve fiber density, improved neurological morphology of sciatic nerves, increased serum neuregulin 1 (NRG1) level and contactin-associated protein (Caspr)-positive paranodes, and decreased amyloid precursor protein (APP) accumulation in DPN rats. More importantly, JMT enriched nine species of the gut microbiota of DPN rats, helping to prevent dysbiosis. Among these species, p_Actinobacteria, p_Proteobacteria and c_Actinobacteria were negatively correlated with DPN phenotypes and positively correlated with serum NRG1 level. These results indicate that JMT may exert a neuroprotective effect by modulating phenotype-associated gut microbiota and increasing serum NRG1 level in STZ-induced DPN rats. JMT may therefore be an effective complementary and alternative anti-DPN therapy.

Abstract
Fucoxanthin (Fx), a marine carotenoid found in edible brown algae, is well known for having anticancer properties. The gut microbiota has been demonstrated as a hallmark for colorectal cancer progression in both humans and rodents. However, it remains unclear whether the gut microbiota is associated with the anticancer effect of Fx. We investigated the chemopreventive potency of Fx and its effect on gut microbiota in a mouse model of inflammation-associated colorectal cancer (by azoxymethane/dextran sulfate sodium treatment). Fx administration (30 mg/kg bw) during a 14 week period significantly inhibited the multiplicity of colorectal adenocarcinoma in mice. The number of apoptosis-like cleaved caspase-3high cells increased significantly in both colonic adenocarcinoma and mucosal crypts. Fx administration significantly suppressed Bacteroidlales (f_uc; g_uc) (0.3-fold) and Rikenellaceae (g_uc) (0.6-fold) and increased Lachnospiraceae (g_uc) (2.2-fold), compared with those of control mice. Oral administration of a fecal suspension obtained from Fx-treated mice, aimed to enhance Lachnospiraceae, suppress the number of colorectal adenocarcinomas in azoxymethane/dextran sulfate sodium-treated mice with a successful increase in Lachnospiraceae in the gut. Our findings suggested that an alteration in gut microbiota by dietary Fx might be an essential factor in the cancer chemopreventive effect of Fx in azoxymethane/dextran sulfate sodium-treated mice.

Abstract
The intestine is a diversified microecosystem whose structure and function are research hotspots in the fields of life sciences and medicine. The research on the regulation of intestinal microecology by traditional Chinese medicine is of great significance to the elucidation of the basic theories and the mechanism of therapeutic effects of traditional Chinese medicine. The micro-ecological research technology is very important for the research in this field. We, by reviewing the relevant literature, summarize the related technologies for the intestinal micro-ecological research of traditional Chinese medicine, such as microbial culture counting method, molecular biology techniques (denaturing/temperature gradient gel electrophoresis (DGGE/TGGE), gene chip, real-time quantitative polymerase chain reaction (PT-PCR), terminal-restriction fragment length polymorphism (T-RFLP), amplified ribosomal DNA restriction analysis (ARDRA), fluorescent in situ hybridization (FISH), high-throughput sequencing (HTS), metabolic level analysis techniques, and proteomics), intestinal enzyme activity detection, microbial activity detection technology, and in vitro simulated gastrointestinal environment experiments, with an aim to provide reference for the intestinal micro-ecological research of traditional Chinese medicine and the application of related technologies.

Abstract
Colorectal cancer (CRC) has become a serious threat to human life and health. Most patients are diagnosed at the late stage of advanced CRC, resulting in losing their best opportunity for surgical treatment. Chemotherapy plays a crucial role in the control and treatment of advanced CRC. However, the cytotoxicity of chemotherapeutic drugs can easily cause the imbalance of gut flora, damage the barrier of the gastrointestinal mucosa, and mediate mucosal inflammation of the digestive tract, which is called "gastrointestinal mucositis." This mucositis can affect the quality of life of the host and even threaten their lives. Several studies reported the association between chemotherapy-mediated gastrointestinal mucositis in CRC and gut dysbiosis. However, the underlying mechanisms of this association are still unclear. The alternative or complementary treatments to reshape gut microbiota and slow down the side effects of chemotherapy have shown the improvement of gastrointestinal mucositis following chemotherapy in the CRC condition. This review will summarize and discuss the evidence of the association between chemotherapy-mediated gastrointestinal mucositis in CRC and altered gut microbiota from in vivo and clinical studies. The possible mechanisms of gastrointestinal mucositis, including the destruction of the gastrointestinal mucosal barrier, the induction of gut dysbiosis, and histopathological changes in the gut of CRC with chemotherapy will be illustrated. In addition, the nonpharmacological interventions and phytochemical extracts by using the manipulation of the microbial population for therapeutic purposes for relieving side effects of chemotherapy as well as a cancer treatment would be summarized and discussed in this review.

Abstract
Cancer is a disease with a high mortality and disability rate. Cancer consists not only of cancer cells, but also of the surrounding microenvironment and tumor microenvironment (TME) constantly interacting with tumor cells to support tumor development and progression. Over the last decade, accumulating evidence has implicated that microbiota profoundly influences cancer initiation and progression. Most research focuses on gut microbiota, for the gut harbors the largest collection of microorganisms. Gut microbiota includes bacteria, viruses, protozoa, archaea, and fungi in the gastrointestinal tract, affecting DNA damage, host immune response and chronic inflammation in various types of cancer (i.e., colon cancer, gastric cancer and breast cancer). Notably, gut dysbiosis can reshape tumor microenvironment and make it favorable for tumor growth. Recently, accumulating studies have attached the importance of traditional Chinese medicine (TCM) to cancer treatments, and the bioactive natural compounds have been considered as potential drug candidates to suppress cancer initiation and development. Interestingly, more recent studies demonstrate that TCM could potentially prevent and suppress early-stage cancer progression through the regulation of gut microbiota. This review is on the purpose of exhausting the significance of gut microbiota in the tumor microenvironment as potential targets of Chinese medicine.

Abstract
Hydroxylated chalcones are phytochemicals which are biosynthetic precursors of flavonoids and their 1,3-diaryl-prop-2-en-1-one structure is used as a scaffold for drug development. In this study, the structure-dependent activation of aryl hydrocarbon receptor (AhR)-responsive CYP1A1, CYP1B1, and UGT1A1 genes was investigated in Caco2 colon cancer cells and in non-transformed young adult mouse colonocytes (YAMC) cells. The effects of a series of di- and trihydroxychalcones as AhR agonists was structure dependent with maximal induction of CYP1A1, CYP1B1, and UGT1A1 in Caco2 cells observed for compounds containing 2,2'-dihydroxy substituents and this included 2,2'-dihydroxy-, 2,2',4'-trihydroxy-, and 2,2',5'-trihydroxychalcones. In contrast, 2',4,5'-, 2'3',4'-, 2',4,4'-trihydroxy, and 2',3-, 2',4-, 2',4'-, and 2',5-dihydroxychalcones exhibited low to non-detectable AhR activity in Caco2 cells. In addition, all of the hydroxychalcones exhibited minimal to non-detectable activity in YAMC cells, whereas 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induced CYP1A1, CYP1B1, and UGT1A1 in Caco2 and YAMC cells. The activity of AhR-active chalcones was confirmed by determining their effects in AhR-deficient Caco2 cells. In addition, 2,2'-dihydroxychalcone induced CYP1A1 protein and formation of an AhR-DNA complex in an in vitro assay. Simulation and modeling studies of hydroxylated chalcones confirmed their interactions with the AhR ligand-binding domain and were consistent with their structure-dependent activity as AhR ligands. Thus, this study identifies hydroxylated chalcones as AhR agonists with potential for these phytochemicals to impact AhR-mediated colonic pathways.

Abstract
Intestinal flora is essential for maintaining host health and plays a unique role in transforming Traditional Chinese Medicine (TCM). TCM, as a bodyguard, has saved countless lives and maintained human health in the long history, especially in this COVID-19 pandemic. Pains of diseases have been removed from the effective TCM therapy, such as TCM preparation, moxibustion, and acupuncture. With the development of life science and technology, the wisdom and foresight of TCM has been more displayed. Furthermore, TCM has been also inherited and developed in innovation to better realize the modernization and globalization. Nowadays, intestinal flora transforming TCM and TCM targeted intestinal flora treating diseases have been important findings in life science. More and more TCM researches showed the significance of intestinal flora. Intestinal flora is also a way to study TCM to elucidate the profound theory of TCM. Processing, compatibility, and properties of TCM are well demonstrated by intestinal flora. Thus, it is no doubt that intestinal flora is a core in TCM study. The interaction between intestinal flora and TCM is so crucial for host health. Therefore, it is necessary to sum up the latest results in time. This paper systematically depicted the profile of TCM and the importance of intestinal flora in host. What is more, we comprehensively summarized and discussed the latest progress of the interplay between TCM and intestinal flora to better reveal the core connotation of TCM.

Abstract
The gastrointestinal microbiota is a multi-faceted system that is unraveling novel contributors to the development and progression of several diseases. Berberine has been used to treat obesity, diabetes mellitus, atherosclerosis, and metabolic diseases in China. There are also clinical trials regarding berberine use in cardiovascular, gastrointestinal, and endocrine diseases. Berberine elicits clinical benefits at standard doses and has low toxicity. The mechanism underlying the role of berberine in lipid‐lowering and insulin resistance is incompletely understood, but one of the possible mechanisms is related to its effect on the gastrointestinal microbiota. An extensive search in electronic databases (PubMed, Scopus, Embase, Web of Sciences, Science Direct) was used to identify the role of the gastrointestinal microbiota in the berberine treatment. The aim of this review was to summarize the pharmacologic effects of berberine on animals and humans by regulation of the gastrointestinal microbiota.

Abstract
Background The microbiota plays an important role in host health. Although rubidium (Rb) has been used to study its effects on depression and cancers, the interaction between microbial commensals and Rb is still unexplored. To gain the knowledge of the relationship between Rb and microbes, 51 mice receiving RbCl-based treatment and 13 untreated mice were evaluated for their characteristics and bacterial microbiome changes. Results The 16S ribosomal RNA gene sequencing of fecal microbiota showed that RbCl generally maintained fecal microbial community diversity, while the shifts in fecal microbial composition were apparent after RbCl exposure. RbCl significantly enhanced the abundances of Rikenellaceae, Alistipes, Clostridium XlVa and sulfate-reducing bacteria including Deltaproteobacteria, Desulfovibrionales, Desulfovibrionaceae and Desulfovibrio, but significantly inhibited the abundances of Tenericutes, Mollicutes, Anaeroplasmatales, Anaeroplasmataceae and Anaeroplasma lineages. With regarding to the archaea, we only observed two less richness archaea Sulfolobus and Acidiplasma at the genus level. Conclusions Changes of fecal microbes may in part contribute to the anticancer or anti-depressant effects of RbCl. These findings further validate that the microbiome could be a target for therapeutic intervention.

Abstract
An ever-growing body of evidence has linked the gut microbiome with both the effectiveness and the toxicity of cancer therapies. Radiotherapy is an effective way to treat tumors, although large variations exist among patients in tumor radio-responsiveness and in the incidence and severity of radiotherapy-induced side effects. Relatively little is known about whether and how the microbiome regulates the response to radiotherapy. Gut microbiota may be an important player in modulating “hot” versus “cold” tumor microenvironment, ultimately affecting treatment efficacy. The interaction of the gut microbiome and radiotherapy is a bidirectional function, in that radiotherapy can disrupt the microbiome and those disruptions can influence the effectiveness of the anticancer treatments. Limited data have shown that interactions between the radiation and the microbiome can have positive effects on oncotherapy. On the other hand, exposure to ionizing radiation leads to changes in the gut microbiome that contribute to radiation enteropathy. The gut microbiome can influence radiation-induced gastrointestinal mucositis through two mechanisms including translocation and dysbiosis. We propose that the gut microbiome can be modified to maximize the response to treatment and minimize adverse effects through the use of personalized probiotics, prebiotics, or fecal microbial transplantation. 16S rRNA sequencing is the most commonly used approach to investigate distribution and diversity of gut microbiome between individuals though it only identifies bacteria level other than strain level. The functional gut microbiome can be studied using methods involving metagenomics, metatranscriptomics, metaproteomics, as well as metabolomics. Multiple ‘-omic’ approaches can be applied simultaneously to the same sample to obtain integrated results. That said, challenges and remaining unknowns in the future that persist at this time include the mechanisms by which the gut microbiome affects radiosensitivity, interactions between the gut microbiome and combination treatments, the role of the gut microbiome with regard to predictive and prognostic biomarkers, the need for multi “-omic” approach for in-depth exploration of functional changes and their effects on host-microbiome interactions, and interactions between gut microbiome, microbial metabolites and immune microenvironment.

Abstract
BACKGROUND The dysregulation of gut microbiota is pivotal in colorectal carcinogenesis. Meanwhile, altered gut microbiome may affect the development of intestinal diseases through interaction with the host genes. However, the synergy between the altered gut microbiota composition and differential expression of specific genes in colorectal cancer (CRC) remains elusive. Thus, we integrated the data from 16S rRNA gene sequences and RNA sequences to investigate the potential relationship between genes and gut microbes in patients with CRC. RESULTS Compared with normal samples, the presence of Proteobacteria and Fusobacteria increased considerably in CRC samples; conversely, the abundance of Firmicutes and Spirochaetes decreased markedly. In particular, the genera Fusobacterium, Catenibacterium, and Shewanella were only detected in tumor samples. Meanwhile, a closely interaction between Butyricimonas and Clostridium was observed in the microbiome network. Furthermore, a total of 246 (differentially expressed genes) DEGs were identified between tumor and normal tissues. Both DEGs and microbiota were involved in bile secretion and steroid hormone biosynthesis pathways. Finally, genes like cytochrome P450 family 3 subfamily A member 4 (CYP3A4) and ATP binding cassette subfamily G member 2 (ABCG2) enriched in these two pathways were connected with the prognosis of CRC, and CRC patients with low expression level of CYP3A4 and ABCG2 had longer survival time. CONCLUSION Identifying the complicated interaction between gut microbiota and the DEGs contributed to further understand the pathogenesis of CRC, and these findings might enable better diagnosis and treatment of CRC patients.

Abstract
Kimchi is composed of various chemopreventive phytochemicals and profuse probiotics, defining kimchi as probiotic foods. Concerns had increased on the modulation of intestinal microbiota on various kinds of systemic diseases. Under the hypothesis that dietary intake of kimchi can be ideal intervention for either ameliorating colitis or preventing colitic cancer, we performed the study to validate the efficolitic cancery of fermented kimchi on preventing colitic cancer. Using azoxymethane-initiated and dextran sulfate sodium-promoted colitic cancer models, we have administrated fermented or non-fermented kimchi to modulate colitic cancer preemptively. Detailed molecular mechanisms were explored. Preemptive administration of fermented kimchi significantly afforded colitic cancer prevention through attenuating inflammasomes (IL-18, IL-1β, caspase-1), enhancing antioxidative (NQO1, GST-π), imposing anti-proliferative (Bax, caspase-3, β-catenin), and affording cytoprotective actions (HSP70, 15-PGDH), while non-fermented kimchi did not prevent colitic cancer. Special recipe cancer preventive kimchi (cpkimchi) was more effective compared to standard recipe fermented kimchi (p<0.01), while non-fermented kimchi (kimuchi) worsened colitic cancer development, telling the importance of fermentation in cancer prevention. Repression of NF-kB p65, induction of tumor suppressive 15-PGDH, and inactivation of ERK1/2 by cpkimchi contributed to colitic cancer prevention. Dietary intake of cpkimchi ameliorated colitis and prevented colitic cancer via concerted anti-inflammatory, antioxidative, and anti-mutagenic actions.

Abstract
Accumulating evidence indicates that the gut microbiota can promote or inhibit colonic inflammation and carcinogenesis. Promotion of beneficial gut bacteria is considered a promising strategy to alleviate colonic diseases including colitis and colorectal cancer. Interestingly, dietary polyphenols, which have been shown to attenuate colitis and inhibit colorectal cancer in animal models and some human studies, appear to reach relatively high concentrations in the large intestine and to interact with the gut microbial community. This review summarizes the modulatory effects of polyphenols on the gut microbiota in humans and animals under healthy and diseased conditions including colitis and colitis-associated colorectal cancer (CAC). Existing human and animal studies indicate that polyphenols and polyphenol-rich whole foods are capable of elevating butyrate producers and probiotics that alleviate colitis and inhibit CAC, such as Lactobacillus and Bifidobacterium. Studies in colitis and CAC models indicate that polyphenols decrease opportunistic pathogenic or proinflammatory microbes and counteract disease-induced dysbiosis. Consistently, polyphenols also change microbial functions, including increasing butyrate formation. Moreover, polyphenol metabolites produced by the gut microbiota appear to have anticancer and anti-inflammatory activities, protect gut barrier integrity, and mitigate inflammatory conditions in cells and animal models. Based on these results, we conclude that polyphenol-mediated alteration of microbial composition and functions, together with polyphenol metabolites produced by the gut microbiota, likely contribute to the protective effects of polyphenols on colitis and CAC. Future research is needed to validate the causal role of the polyphenol-gut microbiota interaction in polyphenols' anti-colitis and anti-CAC effects, and to further elucidate mechanisms underlying such interaction.

Abstract
Diseases of the colon are a big health burden in both men and women worldwide ranging from acute infection to cancer. Environmental and genetic factors influence disease onset and outcome in multiple colonic pathologies. The importance of inflammation in the onset, progression and outcome of multiple colonic pathologies is gaining more traction as the evidence from recent research is considered. In this review, we provide an update on the literature to understand how genetics, diet, and the gut microbiota influence the crosstalk between immune and non‑immune cells resulting in inflammation observed in multiple colonic pathologies. Specifically, we focus on four colonic diseases two of which have a more established association with inflammation (inflammatory bowel disease and colorectal cancer) while the other two have a less understood relationship with inflammation (diverticular disease and irritable bowel syndrome).

Abstract
Sulforaphane (SFN) is a kind of natural isothiocyanate, which exists in cruciferous plants. Only few studies were about the anti-inflammatory effects of sulforaphane in ulcerative colitis. In this study, our purpose is to explore the effects of sulforaphane on the intestinal microbial community of UC mice. The severity of mice colitis were measured by colon length, survial rate, body weight and disease activity index (DAI) score. Histological and morphological evaluation of colon tissues were performed by HE. 16S rRNA gene amplicon pyrosequencing was used to analyza the changes of mouse flora. The variety of flora expression were explored using quantitative PCR. Sulforaphane treated mice had larger body weight and longer colon length than DSS-induced mice. The colon tissues of DSS group showed congestion and edema. Meanwhile, treatment with sulforaphane effectively reducted the damage scores and MPO activity. Sulforaphane reversed DSS-induced gut dysbiosis. Sulforaphane would shift the balance to Butyricicoccus on inflammation. The possible anti-inflammatory mechanism of sulforaphane is to coordinate with the probiotics such as Butyricicoccus. In summary, these findings proved that sulforaphane might be a useful content and serve as a potential therapy in the treatment of UC.

Abstract
Microbiome therapy has attracted a keen interest from both research and business sectors. Our lab has been applying this "second genome" platform to assess the functionality of herbal medicines with fulfilling results. In this study, we applied this platform to assess the potential cancer-preventive effects of three selected adaptogenic plants. The flower buds from these plants were used to constitute Preparations SL and FSP according to the receipts of two commonly consumed Chinese medicinal decoctions for gastrointestinal discomfort. Preparation SL contains Sophorae japonica and Lonicerae Japonicae, and Preparation FSP contains Sophorae japonica and Gardenia Jasminoides. SL and FSP extracts significantly (p < 0.001) lowered the polyp burden, as well as the expressions of oncogenic signaling molecules, such as MAPK/ERK, PI3K/AKT, and STAT3 in ApcMin/+ mice. The inflamed gut was alleviated by shifting M1 to M2 macrophage phenotypes and the associated immune cytokines. The other remarkable change was on the extracellular tight junction protein complex, where the occludin, ZO-1, ICAM-1, E-cadherin were significantly (p < 0.05) upregulated while the N-cadherin and β-catenin were downregulated in the treated mice. The above physiological changes in the gut epithelial barrier were companied with the changes in gut microbiome. The 16S Sequencing data revealed a marked decrease in the potential pathogens (especially Helicobacter species and hydrogen sulfide producing-bacteria) and the increase in beneficial bacteria (especially for species from the genera of Akkermansia, Barnesiella, Coprococcus, Lachnoclostridium, and Ruminococcus). The majority of which were the short-chain fatty acids (SCFAs) producers. Meanwhile SCFAs-sensing G protein-coupled receptors (GPCRs), including GPR41, GPR43, and GPR109a were also significantly upregulated. In a recent report, we proved that the bacteria-derived SCFAs plays an essential role to the anti-cancer effects of the mushroom polysaccharides and saponins in ApcMin/+ mice. In this study, we further demonstrated that butyrate treatment could enhance the extracellular tight junction protein complex as effective as the treatments with SL and FSP to the ApcMin/+ mice. Our findings provide strong evidence of the vital role of the SCFA-producers and their metabolites to the cancer-preventive properties of the SL and FSP preparations.

Ulcerative colitis (UC), a kind of inflammatory bowel disease, is generally characterized by chronic, persistent, relapsing, and nonspecific ulceration of the bowel, which is widespread in the world. Although the pathogenesis of UC is multifactorial, growing evidence has demonstrated that gut microbiota and its metabolites are closely related to the development of UC. Lizhong decoction (LZD), a well-known classical Chinese herbal prescription, has been used to clinically treat UC for long time, but its mechanism is not clear. In this study, 16S rRNA gene sequencing combining with untargeted metabolomics profiling was used to investigate how LZD worked. Results indicated that LZD could shape the gut microbiota structure and modify metabolic profiles. The abundance of opportunistic pathogens such as Clostridium sensu stricto 1, Enterobacter, and Escherichia-Shigella correlated with intestinal inflammation markedly decreased, while the levels of beneficial bacteria including Blautia, Muribaculaceae_norank, Prevotellaceae UCG-001, and Ruminiclostridium 9 elevated in various degrees. Additionally, fecal metabolite profiles reflecting microbial activities showed that adenosine, lysoPC(18:0), glycocholic acid, and deoxycholic acid notably decreased, while cholic acid, α-linolenic acid, stearidonic acid, and L-tryptophan significantly increased after LZD treatment. Hence, based on the systematic analysis of 16S rRNA gene sequencing and metabolomics of gut flora, the results provided a novel insight that microbiota and its metabolites might be potential targets for revealing the mechanism of LZD on amelioration of UC.Key Points • The potential mechanism of LZD on the amelioration of UC was firstly investigated.• LZD could significantly shape the structure of gut microbiota.• LZD could notably modulate the fecal metabolic profiling of UC mice.

Abstract
The human gastrointestinal tract harbors a diverse array of microorganisms that play fundamental roles in health and disease. Imbalance in the gut microbiota, namely dysbiosis, can lead to various diseases, including cancer and gastrointestinal tract disorders. Approaches to improve gut dysbiosis, such as dietary intervention, intake of probiotics, and fecal microbiota transplantation are emerging strategies to treat these diseases. Various medicinal botanicals have reported anti-cancer and/or anti-inflammatory properties. Preclinical studies have illustrated that some of these natural products are also capable to modulate the gut microbiota, suggesting their use as possible alternative approach to improve gut dysbiosis and thereby assist diseases treatment. In this review article, we have summarized the current knowledge on the effects of natural compounds, medicinal plants, and mushrooms on the gut microbiota in various cancers and colitis in preclinical animal models. Challenges towards the clinical use of these medicinal botanicals as modulators of the gut microbiota in cancer and colitis treatment are also discussed.

The Relationship between Prevention and Treatment of Colorectal Cancer and Cancerous Toxin Pathogenesis Theory Basing on Gut Microbiota. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:7162545. [PMID: 32774427 PMCID: PMC7391111 DOI: 10.1155/2020/7162545] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Revised: 08/18/2019] [Accepted: 01/07/2020] [Indexed: 02/07/2023]
Abstract
Gut microbiota is a diverse consortium of bacteria, fungi, protozoa, and viruses in the gut of all mammals. Gut microbiota remains in steady state under normal conditions. Changes in the internal and external environment may cause gut Microbiota to be out of tune. Malignant tumors are one of the major diseases currently endangering human health. CRC (colorectal cancer) has a significant upward trend in morbidity and mortality in many parts of the world. Technological advances have not yet brought about a breakthrough in the efficacy of CRC. The development of colon cancer is closely related to gut microbiota imbalance. According to more than 60 years of clinical practice, Professor Zhongying Zhou first proposed the pathogenesis theory of "cancerous toxin" in the 1990s and believed that cancerous toxin was a key pathogenesis of tumor development. Under the guidance of the theory of cancerous toxin, combined with clinical practice, Professor Zhou created an effective anticancer Chinese herbal compound, Jiedu Xiaoai Prescription. This paper summarizes recent hotspots related to gut microbiota and the occurrence, development, and prevention of colon cancer at home and abroad. The relationship between gut microbiota and cancerous toxin theory is proposed, and the feasibility of further studying the biological basis of cancerous toxin pathogenesis theory from the perspective of gut microbiota is pointed out.

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
Staphylococcus xylosus (S. xylosus) is a type of coagulase-negative Staphylococcus, which was previously considered as non-pathogenic. However, recent studies have linked it with cases of mastitis in cows. Isoliquiritigenin (ISL) is a bioactive compound with pharmacological functions including antibacterial activity. In this study, we evaluated the effect of ISL on S. xylosus in vitro and in vivo. The MIC of ISL against S. xylosus was 80 μg/mL. It was observed that sub-MICs of ISL (1/2MIC, 1/4MIC, 1/8MIC) significantly inhibited the formation of S. xylosus biofilm in vitro. Previous studies have observed that inhibiting imidazole glycerol phosphate dehydratase (IGPD) concomitantly inhibited biofilm formation in S. xylosus. So, we designed experiments to target the formation of IGPD or inhibits its activities in S. xylosus ATCC 700404. The results indicated that the activity of IGPD and its histidine content decreased significantly under 1/2 MIC (40 μg/mL) ISL, and the expression of IGPD gene (hisB) and IGPD protein was significantly down-regulated. Furthermore, Bio-layer interferometry experiments showed that ISL directly interacted with IGPD protein (with strong affinity; KD = 234 μM). In addition, molecular docking was used to predict the binding mode of ISL and IGPD. In vivo tests revealed that, ISL significantly reduced TNF-α and IL-6 levels, mitigated the destruction of the mammary glands and reversed the production of inflammatory cells in mice. The results of the study suggest that, ISL may inhibit S. xylosus growth by acting on IGPD, which can be used as a target protein to treat infections caused by S. xylosus.

JOURNAL OF ETHNOPHARMACOLOGY 2019; 245:112153. [PMID: 31408679 DOI: 10.1016/j.jep.2019.112153] [Citation(s) in RCA: 47] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2019] [Revised: 08/09/2019] [Accepted: 08/09/2019] [Indexed: 05/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Many medicinal plants have been traditionally used for the treatment of gastrointestinal disorders. According to the monographs published by the Committee on Herbal Medicinal Products (HMPC) at the European Medicines Agency, currently 44 medicinal plants are recommended in the European Union for the treatment of gastrointestinal disorders based on traditional use. The main indications are functional and chronic gastrointestinal disorders, such as functional dyspepsia and irritable bowel syndrome (IBS), and typical effects of these plants are stimulation of gastric secretion, spasmolytic and carminative effects, soothing effects on the gastrointestinal mucosa, laxative effects, adstringent or antidiarrheal activities, and anti-inflammatory effects. A possible interaction with human gut microbiota has hardly been considered so far, although it is quite likely. AIM OF THE STUDY In this review, we aimed to identify and evaluate published studies which have investigated interactions of these plants with the gut microbiome. RESULTS According to this survey, only a minor portion of the 44 medicinal plants considered in EMA monographs for the treatment of gastrointestinal diseases has been studied so far with regard to potential interactions with gut microbiota. We could identify eight relevant in vitro studies that have been performed with six of these medicinal plants, 17 in vivo studies performed in experimental animals involving seven of the medicinal plants, and three trials in humans performed with two of the plants. The most robust evidence exists for the use of inulin as a prebiotic, and in this context also the prebiotic activity of chicory root has been investigated quite intensively. Flaxseed dietary fibers are also known to be fermented by gut microbiota to short chain fatty acids, leading to prebiotic effects. This could cause a health-beneficial modulation of gut microbiota by flaxseed supplementation. In flaxseed, also other compound classes like lignans and polyunsaturated fatty acids are present, that also have been shown to interact with gut microbiota. Drugs rich in tannins and anthocyanins also interact intensively with gut microbiota, since these compounds reach the colon at high levels in unchanged form. Tannins and anthocyanins are intensively metabolized by certain gut bacteria, leading to the generation of small, bioavailable and potentially bioactive metabolites. Moreover, interaction with these compounds may exert a prebiotic-like effect on gut microbiota. Gut microbial metabolization has also been shown for certain licorice constituents, but their potential effects on gut microbiota still need to be investigated in detail. Only a limited amount of studies investigated the interactions of essential oil- and secoiridoid-containing drugs with human gut microbiota. However, other constituents present in some of these drugs, like curcumin (curcuma), shogaol (ginger), and rosmarinic acid have been shown to be metabolized by human gut microbiota, and preliminary data also indicate potential gut microbiome modulatory effects. To conclude, the interaction with gut microbiota is still not fully investigated for many herbal drugs traditionally used for gastrointestinal disorders, which offers a vast field for future research.

Abstract
Background:At present, the interpretation of any dysfunction by pathogenic microbial colonization of the digestive tract can be considered as the rupture of the microbiotic balance in the injured or infected area. Phytodrugs with useful properties to balance the intestinal microbiota equibiotics represent an alternative recently proposed by the Medicinal Plant Research Company Phytomedicamenta S.A. The Equibiotic-GI® is a phytodrug developed as a combination of two plant extracts, obtained from the leaves of Psidium guajava L, (Myrtaceae) and the roots of Coptis chinensis Franch. (Racunculaceae). Both plants used traditionally for the treatment of several gastrointestinal disorders.Objective:The aim of the current study was to assess the effect of Equibiotic-GI® suspension on intestinal microbiota of subjects with functional dyspepsia.Methods:An open-label study performed in 8 adult subjects with functional dyspepsia receiving orally 20 mL of the suspension, daily for two weeks. Fecal samples were collected at baseline and the end of treatment for assessing gut microbiota composition by sequencing the V3-V4 region of the 16S rRNA gene.Results:Equibiotic-GI modified the Bacteriodetes/Firmicutes proportion increasing the richness of the microbiota composition and Rikenellaceae and Alistipes abundance.Conclusion:Together with the improvement in the gastrointestinal symptomatology after the consumption of the product, the present study is the first clinical demonstration of the capacity of the Equibiotic-GI® to restore and balance the intestinal microbiota.

Abstract
Gut microbes play a crucial role in the development of colorectal cancer. Chitooligosaccharides (COS), are oligomer that are depolymerized from chitosan and possess a wide range of biological activities. In this study, the effects of COS on colorectal cancer (CRC) development were evaluated using azoxymethane and dextran sulfate sodium (AOM/DSS) induced mouse model of CRC (CACM). In the COS-treated CRC group (CMCOS), COS protected mice from CRC by decreasing the disease activity index, tumor incidences and multiplicity, and the mRNA levels of COX-2, IL-6, TNF-α, IL-1β, IL-10, and IKK-β mRNA in colonic epithelial cells. The results of a cage-exchanged experiment, in which mice from the CACMe and CMCOSe treatments exchanged cages every day to interact with microbes, showed that gut microbes play an important role in preventing CAC by COS. The abundances of fecal bacteria (total bacteria, Lactobacillus, Enterococcus, Fusobacterium nucleatum and butyrate-producing bacteria) were detected by qPCR on the 0th, 1st, 3rd, 6th, 9th, and 10th weekends. Furthermore, microbiota and mycobiota were analyzed by high-throughput sequencing on an Illumina MiSeq PE300 system. COS protected mice from CRC by reversing the imbalance of bacteria and fungi, especially by reducing the abundance of Escherichia-Shigella, Enterococcus, and Turicibacter, and increasing the levels of Akkermansia, butyrate-producing bacteria and Cladosporium.
