Abstract
The human gut microbiota (HGM), a community of trillions of microbes, underscores its contribution by impacting many facets of host health and disease. In the HGM, Bacteroidota and Bacillota represent dominant bacterial phyla, which mainly rely on the glycans recalcitrant to host digestion to meet their energy requirements. Accordingly, the impact of dietary and host-derived glycans in the assembly and operation of these dominant microbial communities continues to be an area of active research. Among various glycans, mannans represent an integral component of the human diet. Apart from their health effects, the diverse and complex mannan structures bears molecular signatures that alter the expression of specific gene clusters in selected Bacteroidota and Bacillota species. Both the phyla possess variable and sophisticated loci of mannan recognition proteins, hydrolytic enzymes, transporters, and other metabolic proteins to sense, capture and utilize mannans as an energy source. The current review summarizes mannan structural diversity, and strategies adopted by select species of the HGM bacteria to forage mannans by focusing primarily on glycoside hydrolases and their effects on host health and metabolism.

Abstract
Epithelial surfaces protect exposed tissues in the body against intrusion of foreign materials, including xenobiotics, pollen and microbiota. The relative permeability of the various epithelia reflects their extent of exposure to the external environment and is in the ranking: intestinal≈ nasal ≥ bronchial ≥ tracheal > vaginal ≥ rectal > blood-perilymph barrier (otic), corneal > buccal > skin. Each epithelium also varies in their morphology, biochemistry, physiology, immunology and external fluid in line with their function. Each epithelium is also used as drug delivery sites to treat local conditions and, in some cases, for systemic delivery. The associated delivery systems have had to evolve to enable the delivery of larger drugs and biologicals, such as peptides, proteins, antibodies and biologicals and now include a range of physical, chemical, electrical, light, sound and other enhancement technologies. In addition, the quality-by-design approach to product regulation and the growth of generic products have also fostered advancement in epithelial drug delivery systems.

Abstract
Simple Summary In recent years, the intake of ultra-processed foods has increased dramatically worldwide. Missing natural foods in the diet raise the need of biologically active food components that could compensate for this deficiency and help maintain proper immune status. In this study, the microbial changes in pigs as experimental animals were assessed as influenced by consumption of oregano extract combination with peppermint and thyme essential oils. The results demonstrated that the combination of plant extracts had a positive effect on the gastrointestinal tract of animals by increasing the number of probiotic bacteria. Based on the results obtained it may be outlined that the combination of oregano extract and peppermint and thyme essential oils can be promising ingredient as a functional component for the development of the new nutraceutical preparation. Abstract In recent years, the intake of ultra-processed foods has increased dramatically worldwide. Missing natural foods in the diet raise the need of biologically active food components that could compensate for this deficiency and help maintain proper immune status. This study used pigs as an animal model for the assessment of the impact of consumption of Origanum vulgare plant extract combined with Mentha piperita and Thymus vulgaris essential oils on microbial profile in intestines. A single group of weaned pigs received basal diet, while the other group basal diet supplemented with plant extract and two essential oils in the form of bilayer tablets prepared using “liquid/solid” phase technology. Metagenomic sequencing was performed with the aim to investigate changes of microbial communities in ileum, caecum, and colon. The results demonstrated that the combination of essential oils was non cytotoxic, and had a positive effect on the microbial composition in the large intestine of pigs due to significant increase in the number of probiotic bacteria. The amount of Lactobacillus was 2.5 times and Bifidobacterium 1.9 times higher in the animal group fed with supplement. The combination, however, had some negative impact on the variety of minor species in the distal part of the ileum. Additional studies need to be performed to obtain knowledge on how combinations of essential oils can change bacterial variety in the proximal part of the gastrointestinal tract.

Both endogenous and exogenous miR-139-5p inhibit Fusobacterium nucleatum-related colorectal cancer development. Eur J Pharmacol 2020; 888:173459.

Abstract
Colorectal cancer (CRC) is one of the most common cancers worldwide. Colorectal carcinogenesis represents a heterogeneous process which influenced by diet, environmental and microbial exposures. Microbes in the gut might take up microRNAs (miRNAs) and these miRNAs might affect microbes in turn. Our previous work identified miR-139-5p as a tumor suppressor gene down-regulated in CRC. At present, the regulatory role and mechanism of miR-139-5p between Fusobacterium nucleatum and CRC are unclear. In this study, after co-incubating Fusobacterium nucleatum with CRC cells, MTT assay, colony formation assay and wound-healing assay showed that Fusobacterium nucleatum could stimulate cell proliferation and migration. After knocking down the expression of c-met in cells, western blot assay proved that knocking down c-met could weaken this stimulation. C-met is one of the target genes of miR-139-5p. Experimented with miR-139-5p overexpressed CRC cell lines, we found the same results as knocking down c-met, which means that endogenous miR-139-5p can reduce the stimulation. Next, by co-incubating the exogenous miR-139-5p mimics with Fusobacterium nucleatum, we proved that exogenous miR-139-5p could inhibit the proliferation of Fusobacterium nucleatum. After treating CRC cells with Fusobacterium nucleatum, which incubated with miR-139-5p mimics in advance, MTT assay indicated that the stimulation of Fusobacterium nucleatum was weakened. Besides, we speculated the binding site between miR-139-5p and Fusobacterium nucleatum. In sum, our study suggests a new prospect for the treatment of CRC, and the combination of Fusobacterium nucleatum and miR-139-5p could be used as a more valuable comprehensive biomarker for CRC prognosis.

Abstract
Traditional Herbal Medicine (THM) has been used for thousands of years, and is popular worldwide due to its effectiveness in a variety of diseases. THM has also formed the basis of the discovery of modern drugs like artemisinin and paclitaxel. However, at present, studies that focus on development in the field of THM are stagnant because currently, the effective ingredients in the herbal formulations and the ambiguity of the underlying mechanisms of action are unknown. In this review, we have investigated the studies available that focused on the efficacy, active ingredients and bioavailability of THM, and the function of gut microbiota in THM-mediated treatment of disease. We hypothesized that most THMs treat diseases via three mechanisms: (1) metabolizing into active metabolites by the action of gut microbiota, (2) regulation of gut microbiota balance, and (3) regulating the fermentation products of the gut microbes. Therefore, focusing on these aspects can help elucidate the pharmacodynamic constituents of THM preparations, and their therapeutic mechanisms of action.

Abstract
To quantify Fusobacterium spp., Enterococcus faecalis (E.faecalis), Enterotoxigenic Bacteroides fragilis (ETBF), and Enteropathogenic Escherichia coli in colorectal cancer (CRC) patients and their possible association with CRC clinicopathogical features, we collected the resected tumors and adjacent normal tissues (N) from 97 CRC patients. 48 age- and sex-matched healthy controls (HC) were also recruited. Real-time PCR was used for bacterial quantification. The median abundance ofFusobacterium spp.(p < 0.001, vs. N; p < 0.01,vs. HC), E.faecalis (p < 0.05, vs. N; p < 0.01, vs. HC) and ETBF (p < 0.001, vs. N; p < 0.05,vs. HC) in tumor tissues was significantly higher than that detected in normal tissue and HC. E.faecalis was detected in 95.88% of tumors and 93.81% of adjacent tissues. Fusobacterium spp. was detected in 72.16% of tumors and 67.01% of adjacent tissues. The combined E.faecalis and Fusobacterium spp. were detected in 70.10% of tumors and 36.08% of adjacent normal tissues. All four bacteria were detected in 33.72% and 22.09% of paired tumor and adjacent normal tissues, respectively. E.faecalis and Fusobacterium spp. are enriched in both tumor and adjacent tissue of CRC patients when compared to HC, suggesting that it is possible to be previously undetected changes in the pathohistologically normal colon tissue in the proximity of the tumor.

Abstract
The objective of the present study was to examine whether Clostridium butyricum supplementation has a role in the regulation of the intestinal flora and the development of the immune system of neonatal mice. A total of 30 pregnant BALB/c mice, including their offspring, were randomly divided into three groups: In the maternal intervention group (Ba), maternal mice were treated with Clostridium butyricum from birth until weaning at postnatal day 21 (PD21) followed by administration of saline to the offspring at PD21-28; in the offspring intervention group (Ab), breast-feeding maternal mice were supplemented with saline and offspring were directly supplemented with Clostridium butyricum from PD21-28; in the both maternal and offspring intervention group (Bb), both maternal mice and offspring were supplemented with Clostridium butyricum at PD 0-21 and at PD21-28. While mice in the control group were given the same volume of normal saline. Stool samples from the offspring were collected at PD14, -21 and -28 to observe the intestinal flora by colony counts of Enterococcus spp., Enterobacter spp., Bifidobacterium spp. and Lactobacillus spp. Detection of intestinal secreted immunoglobulin A (sIgA) levels and serum cytokine (interferon-γ, and interleukin-12, -4 and -10) levels in offspring was performed to evaluate the effect on their immune system. The results revealed that compared with the control group, offspring in the Ba group displayed significantly decreased stool colony counts of Enterococcus spp. (t=3.123, P<0.01) at PD14 and significantly decreased counts of Enterobacter spp. at PD14 and -21 (t=2.563, P<0.05 and t=2.292, P<0.05, respectively). Compared with the control group, the stool colony counts of Bifidobacterium spp. and Lactobacillus spp. were significantly increased in the Ba group at PD21 (t=3.085, P<0.01 and t=2.8508, P<0.05, respectively). The Ab group had significantly higher stool colony counts of Bifidobacterium spp. and Lactobacillus spp. at PD28, compared with the control group (Q=7.679, P<0.01 and Q=6.149, P<0.01, respectively). There were no significant differences identified in the sIgA levels of the intestinal fluid and serum cytokine levels between the control group and the intervention groups. In conclusion, Clostridium butyricum administered to breast-feeding maternal mice was able to regulate the intestinal flora balance in their offspring. However, due to insignificant effects on sIgA level and the associated cytokines, Clostridium butyricum had a limited influence on the balance of type 1 vs. type 2 T-helper cells. However, using Clostridium butyricum as an invention may be a safe method for improving the balance of intestinal flora and associated processes in offspring.

Abstract
Celiac disease remains one of the most challenging pathologies of the small intestine. It involves multiple pathogenic pathways and there are no disease-changing pharmacological agents available against it yet. The term microbiota refers to the community of microorganisms that inhabit a particular region of the body. Normal gut microbiota has a vital role in maintaining the intestinal homeostasis and promoting health. Celiac disease is associated with microbiota alteration, especially with an increase in the number of Gram-negative bacteria and a decrease in the number of Gram-positive bacteria. There is a strong relationship between intestinal dysbiosis and celiac disease, and recent studies are aimed at determining whether the celiac disease is a risk factor for dysbiosis or dysbiosis is for celiac disease. Therefore, the aim of this review was to assess the latest findings regarding the gut microbiota and its impact on the celiac disease, including therapeutic aspects.

Abstract
Species of the genus Nesterenkonia have been isolated from different ecological niches, especially from saline habitats and reported as weak human pathogens causing asymptomatic bacteraemia. Here, for the first time we are reporting the genome sequence and pathogenomic analysis of a strain designated as CD08_7 isolated from the duodenal mucosa of a celiac disease patient, identified as Nesterenkonia jeotgali. To date, only five strains of the genus Nesterenkonia (N. massiliensis strain NP1T, Nesterenkonia sp. strain JCM 19054, Nesterenkonia sp. strain F and Nesterenkonia sp. strain AN1) have been whole genome sequenced and annotated. In the present study we have mapped and compared the virulence profile of N. jeotgali strain CD08_7 along with other reference genomes which showed some characteristic features that could contribute to pathogenicity. The RAST (Rapid Annotation using Subsystem Technology) based genome mining revealed more genes responsible for pathogenicity in strain CD08_7 when compared with the other four sequenced strains. The studied categories were resistance to antibiotic and toxic compounds, invasion and intracellular resistance, membrane transport, stress response, osmotic stress, oxidative stress, phages and prophages and iron acquisition. A total of 1431 protein-encoding genes were identified in the genome of strain CD08_7 among which 163 were predicted to contribute for pathogenicity. Out of 163 genes only 59 were common to other genome, which shows the higher levels of genetic richness in strain CD08_7 that may contribute to its functional versatility. This study provides a comprehensive analysis on genome of N. jeotgali strain CD08_7 and possibly indicates its importance as a clinical pathogen.

Phylogenetic profile of gut microbiota in healthy adults after moderate intake of red wine. Mol Nutr Food Res 2016; 61. [PMID: 27794201 DOI: 10.1002/mnfr.201600620] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2016] [Revised: 10/20/2016] [Accepted: 10/24/2016] [Indexed: 01/22/2023]
Abstract
SCOPE There is growing interest in understanding how human colonic microbiota can be modified by dietary habits. We examined the influence of moderate red wine intake on the colonic microbiota of 15 healthy volunteers, related to the high concentration of polyphenols present in this beverage. The volunteers were classified into high, moderate, and low polyphenol metabolizers (metabotypes) due to their ability to metabolize polyphenols and the results were compared with that of five control (no wine intake) subjects. METHODS AND RESULTS We analyzed the composition, diversity, and dynamics of their fecal microbiota before and after 1 month of wine consumption. The 16S rDNA sequencing allowed detection of 2324 phylotypes, of which only 30 were found over the 0.5% of mean relative frequency, representing 84.6% of the total taxonomical assignments. The samples clustered more strongly by individuals than by wine intake or metabotypes, however an increase in diversity, after the wine intake, was observed. CONCLUSION The results of this study suggest an increase in the global fecal microbial diversity associated to the consumption of red wine, confirm the high variability of the microbiota from different individuals, and show the stability of their singular microbiota composition to small and short-term dietary changes.

Abstract
Gastrointestinal microbiota, consisting of microbial communities in the gastrointestinal tract, play an important role in digestive, metabolic, and immune functioning. Preclinical studies on rodents have linked behavioral and neurochemical changes in the central nervous system with deficits or alterations in these bacterial communities. Moreover, probiotic supplementation in rodents has been shown to markedly change behavior, with correlated changes in central neurochemistry. While such studies have documented behavioral and mood-related supplementation effects, the significance of these effects in humans, especially in relation to anxiety and depression symptoms, are relatively unknown. Thus, the purpose of this paper was to systematically evaluate current literature on the impact of probiotic supplementation on anxiety and depression symptoms in humans. To this end, multiple databases, including Medline, PsycINFO, PubMed, Scopus, and Web of Science were searched for randomized controlled trials published between January 1990 and January 2016. Search results led to a total of 10 randomized controlled trials (4 in clinically diagnosed and 6 in non-clinical samples) that provided limited support for the use of some probiotics in reducing human anxiety and depression. Despite methodological limitations of the included trials and the complex nature of gut-brain interactions, results suggest the detection of apparent psychological benefits from probiotic supplementation. Nevertheless a better understanding of developmental, modulatory, and metagenomic influences on the GI microbiota, specifically as they relate to mood and mental health, represent strong priorities for future research in this area.

[PMID: 27004000 PMCID: PMC4789998 DOI: 10.3748/wjg.v22.i11.3227] [Citation(s) in RCA: 134] [Impact Index Per Article: 16.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2015] [Revised: 10/28/2015] [Accepted: 12/08/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate Fusobacterium nucleatum (F. nucleatum) abundance in colorectal cancer (CRC) tissues and its association with CRC invasiveness in Chinese patients.
METHODS: The resected cancer and adjacent normal tissues (10 cm beyond cancer margins) from 101 consecutive patients with CRC were collected. Fluorescent quantitative polymerase chain reaction (FQ-PCR) was applied to detect F. nucleatum in CRC and normal tissues. The difference of F. nucleatum abundance between cancer and normal tissues and the relationship of F. nucleatum abundance with clinical variables were evaluated. Fluorescence in situ hybridization (FISH) analysis was performed on 22 CRC tissues with the highest F. nucleatum abundance by FQ-PCR testing to confirm FQ-PCR results.
RESULTS: The median abundance of F. nucleatum in CRC tissues [0.242 (0.178-0.276)] was significantly higher than that in normal controls [0.050 (0.023-0.067)] (P < 0.001). F. nucleatum was over-represented in 88/101 (87.1%) CRC samples. The abundance of F. nucleatum determined by 2-ΔCT was significantly greater in tumor samples [0.242 (0.178, 0.276)] than in normal controls [0.050 (0.023, 0.067)] (P < 0.001). The frequency of patients with lymph node metastases was higher in the over-abundance group [52/88 (59.1%)] than in the under-abundance group [0/13 (0%)] (P < 0.005). No significant association of F. nucleatum with other clinico-pathological variables was observed (P > 0.05). FISH analysis also found more F. nucleatum in CRC than in normal tissues (median number 6, 25th 3, 75th 10 vs 2, 25th 1, 75th 5) (P < 0.01).
CONCLUSION: F. nucleatum was enriched in CRC tissues and associated with CRC development and metastasis.

Abstract
Colorectal cancer (CRC) is a very common malignancy in the Western World and despite advances in surgery, chemotherapy and screening, it is still the second leading cause of cancer deaths in this part of the world. Numerous factors are found important in the development of CRC including colonocyte metbolism, high risk luminal environment, inflammation, as well as lifestyle factors such as diet, tobacco, and alchohol consumption. In recent years focus has turned towards the genetics and molecular biology of CRC and several interesting and promising correlations and pathways have been discovered. The major genetic pathways of CRC are the Chromosome Instability Pathway representing the pathway of sporadic CRC through the K-ras, APC, and P53 mutations, and the Microsatellite Instability Pathway representing the pathway of hereditary non-polyposis colon cancer through mutations in mismatch repair genes. To identify early cancers, screening programs have been initiated, and the leading strategy has been the use of faecal occult blood testing followed by colonoscopy in positive cases. Regarding the treatment of colorectal cancer, significant advances have been made in the recent decade. The molecular targets of CRC include at least two important cell surface receptors: the epidermal growth factor receptor and the vascular endothelial growth factor receptor. The genetic and molecular knowledge of CRC has widen the scientific and clinical perspectives of diagnosing and treatment. However, despite significant advances in the understanding and treatment of CRC, results from targeted therapy are still not convincing. Future studies will determine the role for this new treatment modality.
