microbiome and metabolites

We selected all pairs of co-associated metabolites interacting with species (or pathways) with at least 30 missing observations, and built 1,000 random datasets which included 1,000 pairs of metabolites matched by correlation and sample size to the original set of co-associated metabolites. However, its contribution to fat metabolism, particularly in abdominal fat deposition, which is a severe problem in the poultry industry . Goodrich, J. K. et al. Natl Acad. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Fourth, stool consistency and microbial cell count, which can have an influence on the gut microbiota composition50,51, were not recorded in this study. This trend was even stronger when studying the faecalblood dialogue, with nearly 13 times more co-associated metabolite pairs identified by means of the P-gain statistics for microbial metabolic pathways than species. TwinsUK is funded by the Wellcome Trust, Medical Research Council, European Union, the National Institute for Health Research (NIHR)-funded BioResource, Clinical Research Facility and Biomedical Research Centre based at Guys and St. Thomas NHS Foundation Trust in partnership with Kings College London.

ADS Drugs can be metabolised by the gut microbiota, and they may affect both the metabolic activity of the gut microbiome and its composition28,29. Frontiers | Multi-Omic Analysis of the Microbiome and Metabolome in The role of the gut microbiome and its metabolites in metabolic Ann. This dialoguewas wider with the microbial metabolic pathways, involving 70% of the faecal and 14% of blood metabolites, and 67% of the pathways (n=247). Understanding the host-microbe interactions using metabolic modeling Sex-specific effects of organophosphate diazinon on the gut microbiome and its metabolic functions. Petersen, A.-K. et al. If sample scores were greater than three times the standard deviation on one of the first 10 principal components the sample was labelled as outlier and discarded. Identifying personal microbiomes using metagenomic codes. A.V., C.I.L.R., N.R., and M.F. In our analyses, we identified associations between six species and 101 microbial metabolic pathways and 6 out of 11 drugs and drug-related metabolites detected in faeces through the Metabolon platform in a sufficient number of subjects. Antunes, L. C. M. et al. Survival and therapeutic potential of probiotic organisms with reference to Lactobacillus acidophilus and Bifidobacterium spp. Vandeputte, D. et al. The important role that the gut microbiota appears to play in human metabolism and health has stimulated research into the identification of specific microorganisms involved in different processes, and the elucidation of metabolic pathways, particularly those associated with metabolism of dietary components and some host-generated substances. As a consequence, pathway prevalence within our sample strongly correlated with the number of species in which it could be detected (Spearmans =0.34; P=9.4109), i.e., pathways present in the largest number of species were also those with highest prevalence (and vice versa). Finally, we evaluated the P-gain statistic as the ratio between the minimum P value obtained using the single metabolites alone and the P value obtained using their ratio15. Interplay between the human gut microbiome and host metabolism. A strong reduction in P value indicates that two metabolite levels may be linked by a mechanism that involves the gut microbiota. Methods 12, 902 (2015). Next, reads were filtered to remove adapters, known artefacts, phix174, and then quality trimmed (PhRED quality score<10). At a5% FDR, we identified association between the faecal metabolites and 90% of the microbial species and 99.7% of the microbial metabolic pathways. Bifidobacterium longum (B. longum) CCFM1077 has been shown to have lipid-lowering effects in animals.This study aimed to evaluate the potential of B. longum CCFM1077 in lowering the lipid levels in patients with hyperlipidemia and investigate the effect of . A recent study revealed that in colon cancer, bacteria form polysaccharide matrices called biofilms at a high frequency in the proximal colon. Sebacate, threonate, and p-cresol sulfate, in both faeces and blood, showed the largest number of associations with pathways and with species in both faeces and blood.

The bottom of the figure reports the number of associations that were significant at a5% FDR, along with the number and percentage of metabolites, microbial species, and microbial metabolic pathways involved. The human gut is inhabited by a complex and metabolically active microbial ecosystem. (3) Light continuous line: metabolites produced by the host, such as bile acids, affect microbial growth. In contrast, your gut microbiota describes the different microbe . Similarly, correction for drug intake (antibiotics, metformin, and protonproton inhibitor (PPI)), which was assessed in a small subset of our study sample (n=411, see the Methods section), appeared to minimally affect the number of significant associations between the metagenome and the faecal and blood metabolome (Supplementary Table4, Supplementary Data1013).

A 3-mL volume of lysis buffer (20mM TrisHCl pH 8.0, 2mM sodium EDTA 1.2% Triton X-100) was added to 0.5g of stool sample, and the sample vortexed until homogenised. Biotechnol. The Effects of Specific Gut Microbiota and Metabolites on IgA - PubMed Tigchelaar, E. F. et al. Metabolites | Free Full-Text | Metabolome-Microbiome Crosstalk and 33, for blood metabolome. Only pairs of metabolitesspecies/pathways with at least 50 observations were tested for association. We obtained a P-gain threshold of 73 for species and of 42 for metabolic pathways at an experimental-wide -level of 0.05 (see the Methods section). Microbiota Metabolites in Health and Disease - PubMed We find multiple associations between the gut microbiome (taxonomic composition and microbial metabolic function) and faecal and blood metabolites. Nephrol. M.F. We used the top 5% P-gain value as the critical P-gain threshold. Each pathway was observed in a median of 91.6% of the samples, with 12% of the pathways present in all samples and only 2% being sample-specific (Fig. The joint study of microbiome and metabolome has been suggested as the most promising approach to evaluate hostmicrobiome interactions10. Syst. Metabolic control by the microbiome - Genome Medicine (=0.62, SE=0.17, P=2.13104). Franzosa, E. A. et al. Nucleic Acids Res. Notably, a previous study on the TwinsUK cohort observed that 72% of blood metabolites were under host genetic influence33. Opin. Finally, the results obtained in this study are not quantitative, since all analyses were carried out using relative abundances. Google Scholar. Microbiol. Under the assumption that a zero relative abundance meant impossibility to detect the taxum/pathway rather than its absence, zero values were considered as not available (NA). 54, 5561 (2012). USA 108, 46074614 (2011). Maier, L. et al. Sebacate was also used as primary carbon source by some gut commensals (Pseudomonas aeruginosa and Pseudomonas multilivoran)41. Visconti, A., Martin, T. C. & Falchi, M. YAMP: a containerized workflow enabling reproducibility in metagenomics research. Associations passing a FDR threshold of 5% were considered significant. Genet. Again, secondary BAs were more associated (over 70% of all BAs associations) than primary BAs with both species and metabolic pathways. Cell Syst. Sex and age at the sample collection were included as covariates. Million, M. et al. We selected all pairs of metabolites that were observed in at least 100 individuals and were associated with the same species/metabolic pathway in both environments (co-associated metabolites) and used two approaches to detect and validate the presence of an interplay between the gut and the systemic host metabolism.

On the other hand, 31 out of 61 faecal metabolites whose dialogue with blood threonate via M. smithii was confirmed by the P-gain statistic were significantly associated with measures of adiposity (P<0.05/(613)=1.3103; Supplementary Data17). Sci. Chicken cecal microbiota reduces abdominal fat deposition by - Nature More recently, there has been growing interest in understanding the potential role of GM in influencing athletic performance. The human gut is home to trillions of microbes that form a complex community referred to as the gut microbiota. For instance, we observed over 700 associations with vitamin B-related metabolites. is a consultant for Zoe Global Ltd. Moreover, with this study, we make available to the scientific community a unique resource providing a detailed investigation of the dialogue between the microbiome and the faecal and blood metabolome, which will help in pinpointing potential biomarkers and targets capable of modulating the abundances of metabolites and of species and functions relevant for human health for further investigations, and inform microbiology research on potential new metabolic functions of the gut microbiome. Specifically, 4,861 pairs of faecalblood metabolites co-associated with the same species and 108,565 pairs with the same metabolic pathway.

Mendelian randomization: can genetic epidemiology contribute to understanding environmental determinants of disease? The distribution of percentages obtained for species and pathways across all pairs were then compared using a paired Wilcoxons test. We calculated the enrichment of the associated metabolites for metabolic super-pathways (as annotated by Metabolon, Inc.; see the Methods section). Nutr. The Human Gut Microbiome and Body Metabolism: Implications for Obesity W.L., J.C.V., K.E.N. The most ubiquitous species were from the Subdoligranulum genus (unclassified species), Ruminococcus obeum, Ruminococcus torques, and Faecalibacterium prausnitzii, all detected in more than 98% of the samples (Supplementary Fig. Biochim. Enrichment analysis was performed using the super-pathways annotation provided by Metabolon, Inc. Metabolites were grouped in the following eight super-pathways: amino acid, carbohydrate, cofactors and vitamins, energy, lipid, nucleotide, peptide, and xenobiotics. Indeed, these associations showed opposite direction of effects, suggesting that microbes may modulate the absorption of the metabolites by the host rather than its bioavailability. To assess the effect of age in our analyses, associations of faecal and blood metabolites with species and microbial metabolic pathways-transformed relative abundances were carried out using PopPAnTe, with only pairs of metabolitesspecies/pathways with at least 50 observations tested for association. Vremo, L., Nielsen, J. Natl Acad. Functional capabilities of the microbial community were described by the MetaCyc metabolic pathways, and assessed using the UniRef90 proteomic database annotations. An inner joint of the two tables, using the InChi Key as key, highlighted that 155 and 42 of the faecal and blood metabolites annotated in the previous step (and involved in 4891 and 419 unique associations, respectively) were assigned to at least one of the MetaCyc metabolic pathways. Associations between the gut microbiome and metabolome in early life Microbiota-derived tryptophan metabolites indole-3-lactic acid is We assess the impact of the gut microbiome on both the gut and host systemic metabolism by using WMGS and untargeted faecal and blood metabolomics data.

Genomic and metabolic adaptations of Methanobrevibacter smithii to the human gut. We compared the results obtained using an association model that included only sex and age at the sample collection as covariates with those obtained, in the same set of individuals, using an association model which had also information on the use of the three reported drugs (each drug included as fixed effect in the PopPAnTe linear mixed model and coded as: 1=taking the drug or 0=not taking the drug). However, the effects of gut microbiota on the metabolism and bioavailability of arsenosugars in vivo are unknown. Second, we evaluated, for each pair of co-associated metabolites, its P-gain statistic (Supplementary Fig. To inform a more mechanistic understanding of the relationship . Altogether, our results indicate an intense interplay between the gut microbiome and its host. Method: This study employed Mendelian randomization (MR) to investigate the causal association between . Interestingly, 144 out of 309 microbiome-associated blood metabolites (47%) identified in our study were not heritable. In these analyses, we used all the available samples with faecal metabolites (n=479) and with blood metabolites (n=859). Purpose Microorganisms and their metabolites suppress plant parasitic nematodes. 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. Study design and number of associations. Whole-genome sequencing identifies common-to-rare variants associated with human blood metabolites. 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. J. Biol. Finally, we estimated that the microbiome was involved in a dialogue between 71% of faecal, and 15% of blood, metabolites. Furthermore, it has been suggested that the gut microbiota influences the host via a range of microbiota-derived metabolites [62,63]. The results at the taxonomic level were comparable to those previously reported in a recent study on the TwinsUK cohort leveraging 16S rRNA gene amplicon data11. Natl Acad. LeBlanc, J. G. et al. It has previously suggested that a critical P-gain threshold taking into account multiple test correction, under the assumption of a type I error rate of 0.05, would be 10 times the number of tests15.

The Gut Microbiome and Metabolites Are Altered and Interrelated in Gut microbiota-derived metabolites are key molecular mediators between the microbiota and host. All association tests were carried out between pairs of co-associated metabolites and metagenomic data with at least 100 complete observations (i.e., having metagenomic data and metabolic profile for both co-associated metabolites available). BMJ 361,k2179 (2018). Storey, J. D. A direct approach to false discovery rates. The dataset included 161 monozygotic twin pairs (n=322), 201 dizygotic twin pairs (n=402), and 280 singletons. Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. At a5%FDR, a total of 101 associations were observed between microbial metabolic pathways and faecal metabolites annotated as drugs or and drug-derived metabolites (Supplementary Data3). The P-gain statistic compares the increase in strength of association with the species (or pathway) when using the metabolite ratios compared to the smaller of the two P values when using the two metabolite abundances individually. We assessed, through simulations, the probability that the microbiota was involved in the dialogue between faecal and blood metabolites (see the Methods section).

This is in line with previous observations showing that, in absence of external perturbation, the gut microbiome of healthy adults remains relatively stable for years34,35. Measurements >3 standard deviations from the dataset mean were excluded from the analysis. The immune system constantly scans the intestinal microenvironment for information regarding the metabolic state of the microbiota as well as the colonization status. Amplification was performed by Veriti 96-well PCR (Applied Biosystems) followed by AMPure XP bead cleanup (Beckman Coulter, PN. Associations of faecal and blood metabolites with species and microbial metabolic pathways-transformed relative abundances were carried out using PopPAnTe (v, 1.0.2)12, which uses a variance component framework and the matrix of the expected kinship between each pair of individuals, generated using the pedigree information, to model the resemblance between family members. Indeed, while we are not able to measure it, we can confidently assume that a variable proportion of missing data in our dataset are likely to include truly missing species (or pathways). Genet. Turnbaugh, P. J. et al. 800L of supernatant was then transferred to a deep well block and DNA extracted and purified using a Chemagic MSM I (Perkin Elmer) following the manufacturers protocol.

(2) Large dashed lines: the microbiome affects the gut barrier integrity, resulting in alterations of metabolites absorption (i.e., the same metabolite is associated with a species/pathway in both blood and faeces, but the directions of effects are opposite). Zymo Onestep Inhibitor Removal kit was then performed following manufacturers instructions (Zymo Research PN. Article Ridlon, J. M., Kang, D.-J. At a 5% FDR, we identified 360 microbial metabolic pathways associating with 679 faecal and 222 blood metabolites, and 233 microbial species associating with 582 faecal and 160 blood metabolites. Microbial metabolic detection (as described by the MetaCyc microbial metabolic pathways) identified 434 non-redundant pathways, which were detected in most samples (see the Methods section). Finally, we removed individuals not of European ancestry (n=9, self-reported via questionnaire) resulting in 1004 samples with an average number of reads of 39M (39 males, 965 female), all living in the UK at the time of specimen collection (Supplementary Table1).

To ensure the normality of their distribution, the data were rank-based inverse normalised. Soc. The differences in rhizosphere microbial community and interactions, functional genes, and . Our results showed that the gut metagenome (both at the species and at the metabolic pathway levels) widely associates with both the gut and host systemic metabolism. An invitation to the marriage of metagenomics and metabolomics. Then, after having identified all possible pairs of unrelated individuals (n=1,006,288), we assessed for each pair the percentage of shared species/pathways as the ratio between the number of species/pathways which were present in both members and the number of species/metabolic pathways which were present in at least one of them. Threonate in blood showed the highest P-gains involvinga large number of significantly co-associated faecal metabolites(n=61 faecal metabolites, including threonate levels in faeces). Herein, two nori and two kelp samples with phosphate arsenosugar and sulfonate arsenosugar, respectively, as the predominant arsenic species, were administered to normal mice and gut microbiota-disrupted mice treated with the broad .

All authors read and approved the final draft of the manuscript. Next, MetaPhlAn255 (v. 2.6.0) and the HUMAnN2 pipeline56 (v 0.10.0), both included into the YAMP pipeline, were used to characterise the microbial community composition and its functional capabilities, respectively. Another study on rats also revealed the absence of sebacate in faeces after intravenous injection of the radioactive compound40, indicating that it is unlikely that systemic sebacate level affects the gut microbiome through its excretion in the gut. Faecal metabolites associated with microbial species were enriched for a decrease in amino acids (PAGE adj P=1.6104) and an increase in lipids (PAGE adj P=1.9103), while metabolites associated with metabolic pathways were enriched for a decrease in lipids (PAGE adj P=8.0105), and an increase in both nucleotides (PAGE adj P=0.02) and carbohydrates (PAGE adj P=0.03).
