Akkermansia muciniphila - friend or foe in colorectal cancer? Front Immunol 2023; 14:1303795.

Abstract
Akkermansia muciniphila is a gram-negative anaerobic bacterium, which represents a part of the commensal human microbiota. Decline in the abundance of A. muciniphila among other microbial species in the gut correlates with severe systemic diseases such as diabetes, obesity, intestinal inflammation and colorectal cancer. Due to its mucin-reducing and immunomodulatory properties, the use of probiotics containing Akkermansia sp. appears as a promising approach to the treatment of metabolic and inflammatory diseases. In particular, a number of studies have focused on the role of A. muciniphila in colorectal cancer. Of note, the results of these studies in mice are contradictory: some reported a protective role of A. muciniphila in colorectal cancer, while others demonstrated that administration of A. muciniphila could aggravate the course of the disease resulting in increased tumor burden. More recent studies suggested the immunomodulatory effect of certain unique surface antigens of A. muciniphila on the intestinal immune system. In this Perspective, we attempt to explain how A. muciniphila contributes to protection against colorectal cancer in some models, while being pathogenic in others. We argue that differences in the experimental protocols of administration of A. muciniphila, as well as viability of bacteria, may significantly affect the results. In addition, we hypothesize that antigens presented by pasteurized bacteria or live A. muciniphila may exert distinct effects on the barrier functions of the gut. Finally, A. muciniphila may reduce the mucin barrier and exerts combined effects with other bacterial species in either promoting or inhibiting cancer development.

Abstract
The microbiota present in the gastrointestinal tract is involved in the development or prevention of food allergies and autoimmune disorders; these bacteria can enter the gallbladder and, depending on the species involved, can either be benign or cause significant diseases. Occlusion of the gallbladder, usually due to the presence of calculi blocking the bile duct, facilitates microbial infection and inflammation, which can be serious enough to require life-saving surgery. In addition, the biliary salts are secreted into the intestine and can affect the gut microbiota. The interaction between the gut microbiota, pathogenic organisms, and the human immune system can create intestinal dysbiosis, generating a variety of syndromes including the development of food allergies and autoimmune disorders. The intestinal microbiota can aggravate certain food allergies, which become severe when the integrity of the intestinal barrier is affected, allowing bacteria, or their metabolites, to cross the intestinal barrier and invade the bloodstream, affecting distal body organs. This article deals with health conditions and severe diseases that are either influenced by the gut flora or caused by gallbladder obstruction and inflammation, as well as putative treatments for those illnesses.

Abstract
In the last years several human commensals have emerged from the gut microbiota studies as potential probiotics or therapeutic agents. Strains of human gut inhabitants such as Akkermansia, Bacteroides, or Faecalibacterium have shown several interesting bioactivities and are thus currently being considered as food supplements or as live biotherapeutics, as is already the case with other human commensals such as bifidobacteria. The large-scale use of these bacteria will pose many challenges and drawbacks mainly because they are quite sensitive to oxygen and/or very difficult to cultivate. This review highlights the properties of some of the most promising human commensals bacteria and summarizes the most up-to-date knowledge on their potential health effects. A comprehensive outlook on the potential strategies currently employed and/or available to produce, stabilize, and deliver these microorganisms is also presented.

Abstract
The effects of potato starch, isolated from Snowden (SD) and Kitahime (KH) varieties, on cecal fermatation properties in rats were evaluated. In high-amylose cornstarch (HAS), SD and KH groups, cecal acetate and total short-chain fatty acid concentrations were increased and cecal pH was lowered compared to control (CON) group. Further, cecal immunoglobulin A levels were increased and cecal ammonia-nitrogen, p-cresol, skatole and indole concentrations were lowered in HAS, SD and KH groups compared to the CON group. Therefore, potato starch might possess beneficial intestinal fermentation properties.

Abstract
Akkermansia muciniphila (A. muciniphila), an intestinal symbiont colonizing in the mucosal layer, is considered to be a promising candidate as probiotics. A. muciniphila is known to have an important value in improving the host metabolic functions and immune responses. Moreover, A. muciniphila may have a value in modifying cancer treatment. However, most of the current researches focus on the correlation between A. muciniphila and diseases, and little is known about the causal relationship between them. Few intervention studies on A. muciniphila are limited to animal experiments, and limited studies have explored its safety and efficacy in humans. Therefore, a critical analysis of the current knowledge in A. muciniphila will play an important foundation for it to be defined as a new beneficial microbe. This article will review the bacteriological characteristics and safety of A. muciniphila, as well as its causal relationship with metabolic disorders, immune diseases and cancer therapy.

Abstract
In recent years, scientific community has been gathering increasingly more insight on the dynamics that are at play in metabolic and inflammatory disorders. These rapidly growing conditions are reaching epidemic proportions, bringing clinicians and researcher's new challenges. The specific roles and modulating properties that beneficial/probiotic bacteria hold in the context of the gut ecosystem seem to be key to avert these inflammatory and diet-related disorders. Faecalibacterium prausnitzii, Akkermansia muciniphila and Eubacterium hallii have been identified as candidates for next generation probiotics (NGPs) with exciting potential for the prevention and treatment of such of dysbiosis-associated diseases. The challenges of these non-conventional native gut bacteria lie mainly on their extreme sensitivity to O2 traces. If these strains are to be used successfully in food, supplements or drugs they need to be stable and active in humans. In the present review, we present an overall perspective of the most updated scientific literature on the newly called NGPs through the 5W1H (What, Why, Who, Where, When, and How) method, an innovative and attractive problem-solving approach that provides the reader an effective understanding of the issue at hand.

Abstract
Abstract
The effect of a combination of inulin (INU) and polyphenol-containing adzuki bean extract (AE) on intestinal fermentation was examined in vitro using fermenters for 48 h and in vivo using rats for 28 d. The total short-chain fatty acid concentrations in the fermenters were decreased by a combination of INU and AE, but the concentration in the INU + AE group was higher than the cellulose (CEL) and CEL + AE groups. The cecal propionate concentration was increased by a combination of INU and AE compared with their single supplement. The ammonia-nitrogen concentration in the fermenters and rat cecum was decreased by INU and AE. Cecal mucin levels were increased by INU and AE respectively. Therefore, our observations suggested that the combination of INU and AE might be a material of functional food that includes several healthy effects through intestinal fermentation.

Abstract
A marked elevation in the abundance of Bifidobacterium was found in the cecum of rats that were fed a high-fat diet supplemented with an Amano protease preparation (derived from Aspergillus oryzae). The protease preparation contains several digestive enzymes, including acid protease (AcP), alkaline protease, and amylase. We hypothesized that the elevation in the abundance of Bifidobacterium by Amano protease preparation is associated with the digestive enzymes involved in the protease preparation. To test this hypothesis, this study was conducted to investigate if such bifidogenic effect is because of the AcP. Rats were fed a high-fat diet containing purified AcP obtained from the Amano protease preparation for 2 weeks. The numbers of Bifidobacterium in the cecum and feces of rats were markedly elevated by the dietary supplementation of 1 g/kg Amano protease. Bifidobacterium numbers were unaffected by supplementation with purified AcP (0.096 g/kg) at the level equivalent to the AcP amount found in the 1-g/kg Amano protease diet. Bifidobacterium numbers in the cecum and feces, and lactate levels in the cecum were significantly (P<.05) elevated when rats were fed a diet containing 0.384 g/kg AcP (4-fold higher amount of AcP than that used in the 1-g/kg Amano protease diet). Thus, the bifidogenic effect of 1 g/kg Amano protease diet could not be explained by the AcP. However, intriguingly, supplemental AcP was found to cause a significant bifidogenic effect at the dose that is 4-fold higher than that used in the 1-g/kg Amano protease diet.

Abstract
Eczema is frequently the first manifestation of an atopic diathesis and alteration in the diversity of gut microbiota has been reported in infants with eczema. To identify specific bacterial communities associated with eczema, we conducted a case-control study of 50 infants with eczema (cases) and 51 healthy infants (controls). We performed high-throughput sequencing for V3–V4 hypervariable regions of the 16S rRNA genes from the gut fecal material. A total of 12,386 OTUs (operational taxonomic units) at a 97% similarity level were obtained from the two groups, and we observed a difference in taxa abundance, but not the taxonomic composition, of gut microbiota between the two groups. We identified four genera enriched in healthy infants: Bifidobacterium, Megasphaera, Haemophilus and Streptococcus; and five genera enriched in infants with eczema: Escherichia/Shigella, Veillonella, Faecalibacterium, Lachnospiraceae incertae sedis and Clostridium XlVa. Several species, such as Faecalibacterium prausnitzii and Ruminococcus gnavus, that are known to be associated with atopy or inflammation, were found to be significantly enriched in infants with eczema. Higher abundance of Akkermansia muciniphila in eczematous infants might reduce the integrity of intestinal barrier function and therefore increase the risk of developing eczema. On the other hand, Bacteroides fragilis and Streptococcus salivarius, which are known for their anti-inflammatory properties, were less abundant in infants with eczema. The observed differences in genera and species between cases and controls in this study may provide insight into the link between the microbiome and eczema risk.

Abstract
Akkermansia muciniphila is an intestinal anaerobe which has been proposed as a new functional microbe with probiotic properties. However, the species is not included in the European Union qualified presumption of safety (QPS) list and has not yet been assessed. Moreover, products containing A. muciniphila are not on the market and are thus controlled by the Novel Foods Regulation, which requires extensive safety assessment. This review addresses the safety aspects of the use of A. muciniphila based on published information on its functions in humans and predictions based on its activity in model animals. Further, comprehensive studies related to A. muciniphila and its safety properties have gradually appeared and are summarised here. Many of the criteria required for novel food safety assessment in Europe can thus be fulfilled. However, studies focusing on the toxicological properties of A. muciniphila, including long-term and reproduction studies, have not so far been reported and are discussed in the light of the observation that most, if not all, healthy subjects are known to carry this intestinal anaerobe. As this also applies to other beneficial bacteria found in the human intestinal tract, the A. muciniphila case can be seen as a model for the comprehensive safety evaluations required by the European authorities.

[PMID: 26582185 DOI: 10.1002/mnfr.201500480] [Citation(s) in RCA: 61] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2015] [Revised: 10/30/2015] [Accepted: 10/31/2015] [Indexed: 02/06/2023]
Abstract
SCOPE Dietary calcium has been inversely associated with body fat and energy balance. The main scope of this study has been to assess the potential contribution of gut microbiota on energy regulation mediated by calcium. METHODS AND RESULTS Gut microbiota in C57BL/6J mice receiving calcium supplementation under a high-fat (HF) diet were analysed by PCR and their relationships with host metabolic parameters were determined. Calcium conferred a prebiotic-like effect on gut microbiota, and animals presented lower plasmatic endotoxin levels, increased expression of angiopoietin-like 4 in intestine and lower hepatic lipid content, although increased expression of stress markers in adipose tissue and of inflammation in liver was also found. To determine whether slimming effects could be transferred to obese mice, a faecal microbial transplant (FMT) was carried out, showing that host bacteria grown under a HF diet could not be superseded by those from calcium-fed animals. Therefore, FMT was not able to transfer the beneficial effects of calcium. CONCLUSION In conclusion, calcium modulated gut microbiota in a prebiotic manner, establishing a host cross-talk and promoting a healthier metabolic profile. However, lack of effectiveness of FMT suggests the need of further appropriate dietary factors in addition to the bacteria per se.

Beneficial effects of protease preparations derived from Aspergillus on the colonic luminal environment in rats consuming a high-fat diet. Biomed Rep 2015; 3:715-720.

Abstract
The present study investigated the effects of the dietary addition of the protease preparations derived from Aspergillus on the colonic luminal environment. Rats were fed a 30% beef tallow diet with or without the protease preparations, including Amano protease (protease A 'Amano SD', neutral proteases from Aspergillus spp.) or orientase (orientase AY, acid proteases from Aspergillus niger) at the dose of 0.2% for 3 weeks. Cecal Bifidobacterium was significantly elevated in the dietary Amano protease group (194-fold, P<0.05), but not in the orientase group. Lactobacillus was elevated in the two groups (P<0.05). Cecal n-butyrate, propionate and lactate were higher in the Amano protease and orientase groups compared with the controls (P<0.05). Fecal immunoglobulin A and mucins were elevated in the Amano protease group (P<0.05). These results suggest the potential effect of the consumption of Aspergillus-derived protease preparations that are favorable for the colonic luminal environment in rats fed a high-fat diet.

PLoS One 2015; 10:e0125091.

Abstract
The gastrointestinal tract constitutes a physiological interface integrating nutrient and microbiota-host metabolism. Conjugated linoleic acids (CLA) have been reported to contribute to decreased body weight and fat accretion. The modulation by dietary CLA of stomach proteins related to energy homeostasis or microbiota may be involved, although this has not been previously analysed. This is examined in the present study, which aims to underline the potential mechanisms of CLA which contribute to body weight regulation. Adult mice were fed either a normal fat (NF, 12% kJ content as fat) or a high-fat (HF, 43% kJ content as fat) diet. In the latter case, half of the animals received daily oral supplementation of CLA. Expression and content of stomach proteins and specific bacterial populations from caecum were analysed. CLA supplementation was associated with an increase in stomach protein expression, and exerted a prebiotic action on both Bacteroidetes/Prevotella and Akkermansia muciniphila. However, CLA supplementation was not able to override the negative effects of HF diet on Bifidobacterium spp., which was decreased in both HF and HF+CLA groups. Our data show that CLA are able to modulate stomach protein expression and exert a prebiotic effect on specific gut bacterial species.

Abstract
The intestinal microbiota is a complicated ecosystem that influences many aspects of host physiology (i.e. diet, disease development, drug metabolism, and regulation of the immune system). It also exhibits spatial patterning and temporal dynamics. In this review, the effects of internal and external (environmental) factors on intestinal microbiota are discussed. We describe the roles of the gut microbiota in maintaining intestinal and immune system homeostasis and the relationship between gut microbiota and diseases. In particular, the contributions of polysaccharides, as the most abundant diet components in intestinal microbiota and host health are presented. Finally, perspectives for research avenues relating to gut microbiota are also discussed.

Abstract
The human intestinal tract is colonized by a myriad of microbes that have developed intimate interactions with the host. In healthy individuals, this complex ecosystem remains stable and resilient to stressors. There is significant attention on the understanding of the composition and function of this intestinal microbiota in health and disease. Current developments in metaomics and systems biology approaches allow to probe the functional potential and activity of the intestinal microbiota. However, all these approaches inherently suffer from the fact that the information on macromolecules (DNA, RNA and protein) is collected at the ecosystem level. Similarly, all physiological and other information collected from isolated strains relates to pure cultures grown in vitro or in gnotobiotic systems. It is essential to integrate these two worlds of predominantly chemistry and biology by linking the molecules to the cells. Here, we will address the integration of omics- and culture-based approaches with the complexity of the human intestinal microbiota in mind and the mucus-degrading bacteria Akkermansia spp. as a paradigm.

Abstract
BACKGROUND It has been reported that deviations in gut microbiota composition may predispose toward obesity, and specific groups of commensal gut bacteria may harvest energy from food more efficiently than others. Alterations in microbiota compositions of mothers may be transferred to infants and lead to an increased risk of overweight. OBJECTIVE We analyzed the fecal microbiota composition of infants of overweight and normal-weight mothers and assessed the relations of weight and excessive weight gain of mothers during pregnancy on the microbiota of infants. DESIGN Mothers (n = 16) whose prepregnancy body mass index (BMI; in kg/m²) was ≥25 were selected with their infants from a prospective follow-up study of 256 women. Women with a BMI <25 (n = 26) and their infants served as control subjects. At the ages of 1 and 6 mo, infant stool samples were available for the analysis of microbiota composition by fluorescence in situ hybridization combined with flow cytometry and quantitative real-time polymerase chain reaction. RESULTS Infants' fecal microbial composition was related to the weight and weight gain of their mothers during pregnancy. Fecal Bacteroides and Staphylococcus concentrations were significantly higher in infants of overweight mothers during the first 6 mo. Higher weights and BMIs of mothers were related to higher concentrations of Bacteroides, Clostridium, and Staphylococcus and lower concentrations of the Bifidobacterium group. Prevalences of Akkermansia muciniphila, Staphylococcus, and Clostridium difficile groups were lower in infants of normal-weight mothers and of mothers with normal weight gains during pregnancy. CONCLUSION The composition and development of infant gut microbiota are influenced by BMI, weight, and weight gain of mothers during pregnancy.
