Host-microbiome interactions have been shown to play important roles in human health and diseases. Most of the current studies of the microbiome have been performed by genomic approaches through next-generation sequencing. Technologies, such as metaproteomics, for functional analysis of the microbiome are needed to better understand the intricate host-microbiome interactions. However, significant efforts to improve the depth and resolution of gut metaproteomics are still required. In this study, ...[more]

Stool metaproteomics of children with islet autoimmunity

Project description:The gastrointestinal ecosystem is a highly complex environment with a profound influence on human health. Inflammation in the gut, linked to an altered gut microbiome has been associated with the development of multiple human conditions including type 1 diabetes (T1D). Viruses infecting the gastrointestinal tract, especially enteroviruses, are also thought to play an important role in T1D pathogenesis possibly via overlapping mechanisms. Here, we apply an integrative approach to combine comprehensive faecal virome, microbiome and metaproteome data sampled before and at the onset of islet autoimmunity in 40 children. We show strong age and antibody related effects across the datasets. Mastadenovirus infection was associated with profound functional changes in the faecal metaproteome. Multiomic factor analysis modelling revealed proteins associated with carbohydrate transport from the genus Faecalibacterium were associated with islet autoimmunity. These findings demonstrate functional remodelling of the gut microbiota accompanies both islet autoimmunity and viral infection.

Differential Lysis Approach Enables Selective Extraction of Taxon-Specific Proteins for Gut Metaproteomics

Project description:A differential lysis approach was developed with different strength of lysis buffers (urea and/or sodium dodecyl sulfate) and applied on human stool samples to separate different microbial species to increase the depth of metaproteomic measurements. We showed that the lysates dominating by proteins from Gram-positive (G+) or negative bacteria (G-) can be achieved by differential lysis

Evaluating the protein extraction methods for gut metaproteomics

Project description:Human stool samples were collected, microbial cells were harvested and subjected to protein extraction using different protocols for metaproteomics analyses. The protein extraction methods differ from the usage of different lysis buffer (SDS, urea and commercially available B-Per reagent), bead beating, ultrasonication and heating. The impacts of different protein extraction methods on metaproteomics results were evaluated with multiple criteria including protein yields, peptide identifications, taxonomic compositions and functional compositions.

Lysine acetylation in human fecal microbiome

Project description:This study characterized the lysine acetylome in human gut microbiome samples. Briefly, the microbial peptides obtained from human mcirobiome cells were used for lysine acetylated peptide enrichment using anti-acetyl-lysine (Kac) antibody cocktail; the enriched Kac peptides were then identified and quantified using mass spectrometry.

Evaluation of different protein extraction protocols to study human gut microbiota.

Project description:The link between the gut microbiota and the human physiological state has been demonstrated in recent years. High gut microbiota diversity has been linked to many beneficial functions necessary or human health, while dysbiosis has been correlated to different pathological states. In this context, the study of the gut microbiota results of high relevance been necessary the development of different techniques capable of characterizing this complex ecosystem. Metaproteomics has been proved useful in the characterization of complex protein samples becoming a suitable tool for the study of these microbial communities. However, due to the complexity of these samples, protein extraction protocols may affect metaproteomics results. In this context, we evaluated stool sample processing (SSP) and microbial cell disruption, assessing the impact of different protocol modifications in the number of peptides and proteins identified. We compared different stool processing conditions and microbial cell disruption methods in terms of protein and peptide identifications and taxonomic profiles.

Isobaric Labeling Quantitative Metaproteomics for the Study of Gut Microbiome Response to Arsenic

Project description:Quantitative metaproteomics is a relatively new research field by applying proteomics technique to study microbial proteins of microbiome, and holds the great potential to truly quantify the functional proteins actually expressed by microbes in the biological environment such as gastrointestinal tract. The significant association between arsenic exposure and gut microbiome perturbations has been reported; however, metaproteomics has not yet been applied to study arsenic induced proteome changes of microbiome. Most importantly, to our knowledge, isobaric-labeling based large-scale metaproteomics has not been reported using the advanced database search approaches such as MetaPro-IQ and matched metagenome database search strategies to provide high quantification accuracy and less missing quantification values. In the present study, a new experimental workflow coupled with isobaric labeling and MetaPro-IQ was demonstrated for metaproteomics study of arsenic induced gut microbiome perturbations. The advantages of this workflow were also discussed. For all 18 fecal samples analyzed, 7,611 protein groups were quantified without any missing values. The consistent results of expression profiles were observed between 16S rRNA gene sequencing and metaproteomics. This isobaric labeling based workflow demonstrated the significant improvement of quantitative metaproteomics for gut microbiome study.

Metaproteomic responses of in vitro gut microbiomes to resistant starches

Project description:Resistant starches (RS) are dietary compounds processed by the gut microbiota into metabolites, such as butyrate, that are beneficial to the host. The production of butyrate by the microbiome appears to be affected by the plant source and type of RS as well as the individual’s microbiota. In this study, we used in vitro culture and metaproteomic methods to explore the consistency and variations in individual microbiome's functional responses to three types of RS - RS2(Hi Maize 260), RS3(Novelose 330) and RS4(Fibersym RW). Results showed that RS2 and RS3 significantly altered the levels of protein expression in the individual gut microbiomes, while RS4 did not result in significant protein changes. Significantly elevated protein groups were enriched in carbohydrate metabolism and transport functions of families Eubacteriaceae, Lachnospiraceae and Ruminococcaceae. In addition, Bifidobacteriaceae was significantly increased in response to RS3. We also observed taxon-specific enrichments of starch metabolism and pentose phosphate pathways corresponding to this family. Functions related to starch utilization, ABC transporters and pyruvate metabolism pathways were consistently increased in the individual microbiomes in response to RS2 and RS3; in contrast, the downstream butyrate producing pathway response varied. Our study confirm that different types of RS have markedly variable functional effects on the human gut microbiome, and also found considerable inter-individual differences in microbiome pathway responses.

Metaproteomic analysis of gut microbiota from 30 samples of cystic fibrosis infants

Project description:The link between human gut microbiota (a complex group of microorganisms including not only bacteria but also fungi, viruses, etc.,) and the physiological state is nowadays unquestionable. Metaproteomic has emerged as a useful technique to characterize this microbial community, not just taxonomically, but also focusing on specific biological processes carried out by gut microbiota that may have an effect in the host health or pathological state. Cystic fibrosis is a genetic disease in which the microbiota of the respiratory tract determines the patient's survival and differences in composition of gut microbiota of cystic fibrosis patients respect to healthy infants have been reported. In order to characterize this host-microbiota inter-relation, we carried out the metaproteomic study of 30 stool samples from infants with cystic fibrosis.
