Intestinal microbiota has an enormous metabolic potential and it affects both the nutrition and health of the host. The gut microbiome is a complex and metabolically active community that directly influences host phenotypes. The microbiota plays a major role in . This signaling interacts with host metabolism in ways we are just beginning to understand. Indoor microbial exposure is associated with asthma, but the health effects of indoor metabolites and chemicals are not comprehensively assessed. This study examined the association of equol production with obesity and explored the mediating roles of equol-related gut microbiota and microbial carnitine metabolites. The microbiome associates with host systemic metabolites Blood metabolomics profiling was available for 859 individuals with WMGS data. The metabolomics results showed alterations in some metabolic pathways, especially pathways for lipid metabolism. Microbiome Function in the Gut: The Role of Microbiome-Derived Metabolites Nearly all our knowledge concerning the function of the microbiome comes from studies of the gut. We observed that some pathogenic bacteria, including Vibrio, were significantly increased in psoriasis patients. Video Abstract Introduction The gut microbiome is a source of these potentially disease-modifying bioactive metabolites, and has recently been suggested to contribute to the pathogenesis of neurological disorders 7,8 by . Furthermore, the population of Lactobacillales was identified to be strongly associated with lower Enterobacteriales colonization, higher BW means, and lower . Our microbiome. Background Diet has a large influence on gut microbiota diversity and function. A major metabolic activity of the intestinal microbiome is the conversion of ingested dietary fiber and mucosal glycans into short-chain fatty acids (SCFAs), which include acetate, propionate, and butyrate [ 43 ]. Crohn's disease (CD) is a subtype of inflammatory bowel disease (IBD) characterized by chronic recurrent colonic mucosal inflammation. We postulate that perturbations of human gut microbiome-metabolome interface influentially affect the development of RNET. The Integrated metabolite and microbiome analysis demonstrates that gut metabolites and their association with gut microbiota are perturbed along colorectal carcinogenesis. A variety of secondary metabolites have recently been revealed to have the ability to shape microbiome composition. In the current study, we conducted an integrated analysis of gut microbiota, microbial metabolites in fecal and serum samples, and cardiometabolic phenotypes among AMI cases and controls. Subgroup identification and prediction based on CAGs and CAD-associated metabotypes Introduction. The microbiota is a complex ecosystem of microorganisms consisting of bacteria, viruses, protozoa, and fungi, living in different districts of the human body, such as the gastro-enteric tube, skin, mouth, respiratory system, and the vagina. In this study, we profile gut microbiota using 16S rRNA gene sequencing in 531 well-phenotyped Finnish men from the Metabolic Syndrome In Men (METSIM) study. Using a 5/6 nephrectomized (NX) rat model, we . However, there are few studies on the gut microbiota of captive and wild North China leopard (Panthera pardus japonensis). How long these outcomes require to reach a steady-state, how they relate . We now report the influences of the gut microbiota, metabolites, and DEPs on the mediation of NSCLC's chronic inflammation and immune dysregulation. We found 10 microbial species, mostly opportunist pathogenic bacteria, were related to AMI and cardiometabolic phenotypes. We find that BBIBP-CorV vaccination is accompanied by altered microbiome composition and functional pathways, and the gut microbiome and its functional profiles correlate with the vaccine response. This Special Issue highlights an analysis of . Finally, to assess a potential role of SCFAs (metabolites of fiber fermentation by gut microbiota) in mediating gut-brain dysfunction, the parameters of the gut-brain axis were examined in SCFA receptor knockout (GPR41 / and GPR43 /) mice, and also in mice with SCFA supplementation in a fiber-deficient diet. Impact of gut microbiome and its metabolites on CNS macrophages The gut microbiome affects the functions of CNS macrophages. Faecal and blood samples were collected, on average, 0.9. Numerous . The microbiome is the collection of all microbes, such as bacteria, fungi, viruses, and their genes, that naturally live on our bodies and inside us. Their composition and abundance can be varied, depending on internal factors (e.g., host genetics) and external factors (e.g., diet, lifestyle, and drugs) ( 12 ). The gut microbiome and immune system form an integrated system that protects the host from pathogens and maintains homeostasis. The investigators will perform single-dose pharmacokinetic (PK) studies in humans following administration of drugs with known microbiome derived metabolism (MDM) in parallel with preclinical studies. Unfortunately, thus far, there is a paucity of sufficient knowledge of gut microbiome and related metabolites on CKD progression partly due to the severely limited investigations. However, the composition and diversity of the gut microbiome can be readily affected by external factors, which . A whole host of plant lignins can be found in seeds, nuts, berries, grains, and other foods, most of which are metabolized into enterodiol and sometimes further converted into enterolactone. Environmental signals and diet influence microbiota metabolism. Environ Health Perspect 125:198-206. Background: The human intestine is host to an enormously complex, diverse, and vast microbial communitythe gut microbiota. One such metabolite, implicated in several diseases, including cancer, is trimethylamine N-oxide (TMAO) (17-19 . The study authors draw a strong connection between the loss of these . In this study, we performed 16S rDNA sequencing and liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based nontargeted metabolomic profiling on feces of 26 untreated RA patients and 26 healthy controls. Metabolic disorders represent a growing worldwide health challenge due to their dramatically increasing prevalence. Spearman rank correlation analysis implied that Colidextribacter , Adlercreutzia , Family_XIII_AD3011_group , Lachnospiraceae_UCG-010 , Eisenbergiella, and UCG-005 were robustly . Objectives: Many studies have investigated the effects of soy isoflavones on weight control, but few have focused on the role of equol, a gut-derived metabolite of daidzein with greater bioavailability than other soy isoflavones. Some microbiota-derived metabolites are known to have a positive impact on the host. A former bacterium themselves, mitochondria are part of our global microbiome, a universe of microorganisms that outnumber human cells 100:1 in our own body. In recent years, intestinal health issues have gained attention and many studies have shown that oxidative stress, inflammation, intestinal barrier damage, and an imbalance of intestinal microbiota may cause a range of . In the human body, the intestine is the largest digestive and immune organ, where nutrients are digested and absorbed, and this organ plays a key role in host immunity. 14, 15 among the most studied are short-chain fatty acids (scfas),. Meanwhile, NF regulated the gut microbiota, characterized by decreased BSH-producing genus, 7-dehydroxylation genus, and increased taurine metabolism-related genus. Little is known on mechanistic alteration in the pathogenesis of such disease. We investigate gut microbiota relationships with a variety of factors that have an impact on the development of metabolic and . To investigate the gut microbiota and metabolites in TC patients, we first recruited a total of 50 preoperative subjects with thyroid nodule lesions from the Department of Oncology and Laparoscopy Surgery of the First Affiliated Hospital of Harbin Medical University between September 2017 and February 2018. Gut microbiome, which is considered as a new metabolic organ, is involved in regulating host metabolism. On the one hand, to thrive, gut bacteria exploit nutrients digested by the host. While some microbes, such as Prevotella copri and Blastocystis spp., were indicators of favorable postprandial glucose metabolism, overall microbiome composition was predictive for a large panel of cardiometabolic blood markers including fasting and postprandial glycemic, lipemic and inflammatory indices. Results The microbiota regulates several important metabolic mechanisms of the body, and is associated with metabolic diseases and other disorders. This study provides insight into specific intestinal microbiota and metabolism pathways linked with MSC treatment, suggesting a new approach to the treatment of CD. These products of microbial metabolism thereby interface with the immune, metabolic, or nervous systems of the host to influence physiology . It is well known that an unhealthy lifestyle is a major risk factor for metabolic diseases, while in recent years, accumulating evidence has demonstrated that the gut microbiome and its metabolites also play a crucial role in the onset and development of many metabolic diseases, including obesity, type 2 diabetes, nonalcoholic fatty liver disease, cardiovascular disease and so on. Finally, bacterial . Sugar appears to tip the microbiome balance away from bacteria that support immune cells in favor of non-beneficial bacteria. Microbiota in the intestine of an animal species has evolved together with the host. Here, we characterized the gastric microbiome and metabolome profiles of 37 GC tumor tissues and matched non-tumor tissues using 16s rRNA gene sequencing and ultrahigh performance liquid. In the gut, SCFAs play the most important role in modulating host physiology. However, improved methods for the analysis of the host-microbiome co-metabolism are steadily emerging and developing. . Results A total of 10 mainly bacterial phyla were identified in the fecal . The basis of this interaction is in part mediated by the release of microbially-derived metabolites that enter the circulation. Metabolites secreted by certain microbes (eg, endocannabinoids (eCBs)), generated by microbial digestion of dietary components (eg, short chain fatty acids (SCFAs)) or by transformation of host-derived factors (eg, eCBs and bile acids) can be sensed through various receptors and pathways to alter intestinal integrity and host health. The gut microbiome, a vital and direct environmental contributor to central nervous system development, consists of a vast bacterial and viral community that can significantly influence host health and disease (5, 6).The gut bacterial microbiome has gained the greatest attention. The crosstalk between the host and its microbiome occurs in part through the secretion of metabolites, which have a profound effect on host physiology. The gut microbiome produces a variety of metabolites in the process of degrading dietary factors ; some of these can trigger inflammatory responses and thus contribute to regulating immune function and disease processes (16, 17). This coevolution has produced specific host-microbe combinations, called superorganisms, with the best possible fitness in a given environment. Most of the functions of the microbiome are exerted through microbiome-derived metabolites. in addition to the example of tmao as a potential key player, other microbiota-derived metabolites, such as those produced from aromatic amino acids, have been linked with anti-inflammatory. Driven by the host's genetic makeup and environmental exposures, the gut microbiome and its metabolites have been implicated as the causes and regulators of CRC pathogenesis. The possible use of fecal microbiota-related parameters and microbiota-derived metabolites as biomarkers of cognitive performance and dementia is critically reviewed in this paper, focusing on the most promising areas of research for the future. Several pathological conditions including metabolic psycho-immune diseases and cancers have been associated with changes in the structure and function of intestinal microbiota (Wang . Host-microbial interactions are in part mediated by the immune response ( Round and Mazmanian, 2009 ), and possibly via specialized metabolites ( Ursell et al., 2014 ). Sex-specific effects of organophosphate diazinon on the gut microbiome and its metabolic functions. In CD, inflammation can be . Accumulation of evidence suggests that the gut microbiome, its specific metabolites, and differentially expressed proteins (DEPs) are related to non-small cell lung cancer (NSCLC) pathogenesis. Future longitudinal studies are essential to explore whether the modulation of the gut microbiota and metabolism can alter the natural course of LADA; the mechanisms involved in immune regulation by commensal bacteria in LADA need further investigation. Over 70% of the microbiota lives in the gastrointestinal tract in a mutually beneficial relationship with its host. The levels of short-chain fatty . These include those with anti-inflammatory activity, anti-oxidant activity, and pain relief activity, as well as those acting as vitamins or energy sources, and those that regulate gut barrier function. . On the other hand, the host utilizes numerous products of gut bacteria metabolism as a substrate for ATP production in the colon. The inclusion criteria for patients . Disruptions to the generally consistent metabolic activity of the microbiome can contribute to obesity and metabolic disease 7,8,17,18 through the dysregulation of lipid and carbohydrate metabolism. The gut microbiome and metabolic functions are investigated using metagenomic sequencing and metabolomic assays. Methods The interactions between the gut microbiome and metabolome play an important role in human health and diseases. In the last 10 years, the gut microbiome has emerged as a major regulator of host energy homeostasis and substrate metabolism (24-26).The human gastrointestinal tract is colonized with 4644 bacterial species encoding 171 million genes ().Therefore, it is not unexpected that abnormalities in gut microbiome structure and especially function might affect the brain, adipose tissue, muscle, and . The vastly expanded enzymatic repertoire and corresponding (bio)chemical capabilities of the microbiota compared to the human host increases the complexity of metabolomics studies. Dysbiosis of the gut microbiome and related metabolites in chronic kidney disease (CKD) have been intimately associated with the prevalence of cardiovascular diseases. Background Gut microbes significantly contribute to nutrient digestion and absorption, intestinal health and immunity, and are essential for the survival and environmental adaptation of wild animals. Metabolic disorders are associated with alterations in the composition and function of . The human microbiome may be modulated with prebiotics, probiotics, and postbiotics to potentially aid in the treatment of diseases like irritable bowel syndrome, bacterial vaginosis, atopic dermatitis, gingivitis . Characterisation of gut microbiota shows that low-dose radiation enhances the metabolic defects induced by high-fat diet in mice, in a manner involving increased levels of pyrrolidinecarboxylic acid. They belong to different classes including metabolites generally occurring in plant kingdom as well as specialised metabolised found in only a handful of taxa ().Prominent among such metabolites are the glucosinolates [], flavonoids [11,12] coumarins [13, 14, 15], benzoxazinoids . Here, we collected classroom dust from 24 junior high schools in three geographically distanced areas in Malaysia, including Johor Bahru, Terengganu, and Penang, and conducted culture-independent high-throughput microbiome and untargeted metabolomics . We assessed human fecal samples as noninvasive and unbiased surrogates to catalog the gut microbiota and metabolome in patients with CRC.
