Gut microbial communities enriched with quaternary amines

ABSTRACT: Human fecal communities were dosed with either choline, carnitine, butyrobetaine, or glycine betaine to measure the microbial response to quaternary amine addition. Samples were digested with trypsin, and analyzed by LC-MS/MS. Data was searched with MS-GF+ using PNNL's DMS Processing pipeline.

<h4>Importance</h4>One of the most-cited examples of the gut microbiome modulating human disease is the microbial metabolism of quaternary amines from protein-rich foods. By-products of this microbial processing promote atherosclerotic heart disease, a leading cause of human mortality globally. Our research addresses current knowledge gaps in our understanding of this microbial metabolism by holistically inventorying the microorganisms and expressed genes catalyzing critical atherosclerosis-prom ...[more]

Transcript profiling in the liver of piglets fed carnitine

Project description:Carnitine is a water soluble quaternary amine which is essential for normal function of all tissues. Besides improving performance characteristics of livestock animals carnitine has attracted scientific interest due to several health-related effects, like protection against neurodegeneration, mitochondrial decay, and oxidative stress, improvement of glucose tolerance and insulin sensitivity as well as reduction of hepatic steatosis. To gain insight into mechanisms through which carnitine exerts its beneficial metabolic effects, we fed piglets either a control or a carnitine supplemented diet, and analyzed the transcriptome in the liver, which plays a central role in whole body metabolism. Total RNA was isolated from pig liver samples for hybridization on Affymetrix GeneChip porcine genome arrays. Two RNA pools, each for the control group and the carnitine group, were used. Each RNA pool comprised RNA from 4 pigs.

carnitine effect-Effect of carnitine on the transcriptome of A. thaliana

Project description:rs07-01_carnitine - carnitine effect - Effect of carnitine on the transcriptome of A. thaliana - Our objective is the description of the existence of an intracellular transport depend on the carnitine at Arabidopsis thaliana. For that, we planned the study of the response of the transcriptome in the presence of exogenic L-carnitine. Seedlings WT are cultivated on medium MS, 6 independent times. At 144h, the seedlings are collected and pools are formed with 3 samples. We proceed in the same way for the seedlings which are cultivated on medium MS containing L-carnitine 5mM. Keywords: treated vs untreated comparison

Transcriptional Response to C1 and methylated compounds in Pelagibacter HTCC1062

Project description:Recent studies have shown that Pelagibacter oxidize a wide range of one carbon (C1) and methylated compounds that are ubiquitous in the oceans. However, the metabolic pathways used to oxidize and assimilate these compounds are complex and have been only partly described. To understand the metabolism of these compounds in Pelagibacter and to identify candidate genes involved in these pathways, we used microarray to study changes in gene expression in response to five different compounds (trimethylamine N-oxide (TMAO), methylamine, dimethylsulfoniopropionate (DMSP), methanol, and glycine betaine (GBT)) in Pelagibacter strain HTCC1062. This project will examine the transcriptional response of the marine microorganism Pelagibacter HTCC1062 to five methylated compounds. To do this, 18 flasks were innoculated with cells - 3 flasks without any methylated compounds and rest of 15 treated with different methylated compounds respectively (TMAO (trtmA), methylamine (trtmB), DMSP (trtmC), methanol (trtmD) and glycine betaine (trtmE)). Cells were all harvested at the same timepoint in the exponential phase.

Alterations in Bacillus subtilis caused by high salinity and the compatible solute glycine betaine

Project description:Cells were grown aerobically at 37 degC in Spizizen minimal medium either supplemented with 1 mM glycine betaine, 1.2 M NaCl or 1.2 M NaCl and 1 mM glycine betaine. Cells were harvested in the exponential growth phase at an OD600nm of 1.0. Proteome analysis was performed with samples from three biological replicates.

Characterization of the GbdR regulon in Pseudomonas aeruginosa

Project description:Pseudomonas aeruginosa displays tremendous metabolic diversity, controlled in part by the abundance of transcription regulators in the genome. We have been investigating P. aeruginosaM-bM-^@M-^Ys response to the host, particularly changes regulated by the host-derived quaternary amines choline and glycine betaine (GB). We previously identified GbdR as an AraC-family transcription factor that directly regulates choline acquisition from host phospholipids (via binding to plcH and pchP promoters), is required for catabolism of the choline metabolite GB, and is an activator that induces transcription in response to GB or dimethylglycine. Our goal was to characterize the GbdR regulon in P. aeruginosa using genetics and chemical biology in combination with transcriptomics and in vitro DNA-binding assays. Here we show that GbdR activation regulates transcription of 26 genes from 12 promoters; 11 of which have measureable binding to GbdR in vitro. The GbdR regulon includes the genes encoding GB, dimethylglycine, sarcosine, glycine, and serine catabolic enzymes, and the BetX and CbcXWV quaternary amine transport proteins. . Additionally, identification of two uncharacterized regulon members suggests roles for these proteins in response to choline metabolites. The conditions for inclusion in the gbdR regulon were: (i) called present in the array, (ii) changed more than 2.5-fold in signal in a statistically significant manner, (iii) altered in all three 'inducing' conditions (ethylcholine, choline+propargylcholine, and choline in the dgcA mutant), but (iv) not induced in the wild-type choline or diethylcholine treatments. Wild type and dgcA mutant cells were pre-grown in MOPS minimal media and then split and resuspended in MOPS pyruvate, MOPS pyruvate + choline, MOPS pyruvate + ethylcholine, MOPS pyruvate + diethylcholine, or MOPS pyruvate & choline + propargylcholine.

The minimum low-salt stimulon in Vibrio parahaemolyticus

Project description:Global gene expression profiles of V. parahaemolyticus grown under 2% and 0.66% NaCl were compared to define the minimum low-salt stimulon. The ectABC-lysC operon for synthesis of the compatible solute ectoine, as well as three compatible-solute transport systems, namely ProU (glycine betaine), OpuD1 (glycine betaine) and Pot2 (spermidine), was up-regulated under 2% NaCl in relative to 0.66% NaCl. The 2% NaCl condition favored the inducible expression of OmpW, OmpN and OmpA2, while repressed the expression of OmpA1, OmpU and VP1008. These results indicated that, to master the hyperosmotic stress of saline environments, V. parahaemolyticus might not only accumulate osmoprotectants through uptake or endogenous synthesis of compatible solutes, but also remodel its profiles of outer membrane protein to restore its cell membrane. The above differentially regulated genes will provide novel candidates for the further investigation of the molecular mechanisms of osmoadaptation in V. parahaemolyticus.
