Association Between the Gut Microbiota and Blood Pressure in a Population Cohort of 6953 Individuals

Niiranen , MD, PhD BACKGROUND: Several small-scale animal studies have suggested that gut microbiota and blood pressure (BP) are linked. However, results from human studies remain scarce and conflicting. We wanted to elucidate the multivariable-adjusted as- sociation between gut metagenome and BP in a large, representative, well-phenotyped population sample. We performed a focused analysis to examine the previously reported inverse associations between sodium intake and Lactobacillus abun- dance and between Lactobacillus abundance and BP. METHODS AND RESULTS: We studied a population sample of 6953 Finns aged 25 to 74 years (mean age, 49.2±12.9 years; 54.9% women). The participants underwent a health examination, which included BP measurement, stool collection, and 24-hour urine sampling (N=829). Gut microbiota was analyzed using shallow shotgun metagenome sequencing. In age- and sex-adjusted models, the α (within-sample) and β (between-sample) diversities of taxonomic composition were strongly re- lated to BP indexes (P<0.001 for most). In multivariable-adjusted models, β diversity was only associated with diastolic BP (P=0.032). -

Naturforsch. 56c, 1015-1021 (2001); received June 27/August 6 , 2001 Chlorophyll, Chlorophyllase, Capsicum annuum The in vitro properties of semi-purified chlorophyllase (chlorophyll-chlorophyllido hy drolase, EC 3.1.1.14) from Capsicum annuum fruits have been studied. The enzyme showed an optimum of activity at pH 8.5 and 50 °C. Substrate specificity was studied for chlorophyll (Chi) a, Chi b, pheophytin (Phe) a and Phe b, with K m values of 10.70, 4.04, 2.67 and 6.37 ^im respectively. Substrate inhibition was found for Phe b at concentrations higher than 5 ^m. Chlorophyllase action on Chi a ’ and Chi b' was also studied but no hydrolysis was observed, suggesting that the mechanism of action depends on the configuration at C-132 in the chloro phyll molecule, with the enzyme acting only on compounds with R132 stereochemistry. The effect of various metals (Mg2+, Hg2+, Cu2+, Zn2+, Co , Fe2+ and Fe3+) was also investigated, and a general inhibitory effect was found, this being more marked for Hg2+ and Fe2+. Func tional groups such as -SH and -S-S- seemed to participate in the formation of the enzyme- substrate complex. Chelating ion and the carbonyl group at C3 appeared to be important in substrate recognition by the enzyme. -

Received: 7 August 2017; Accepted: 4 September 2017; Published: 8 September 2017 Abstract: Chinese narcissus (Narcissus tazetta var. chinensis) is one of the ten traditional flowers in China and a famous bulb flower in the world flower market. However, only white color tepals are formed in mature flowers of the cultivated varieties, which constrains their applicable occasions. Unfortunately, for lack of genome information of narcissus species, the explanation of tepal color formation of Chinese narcissus is still not clear. Concerning no genome information, the application of transcriptome profile to dissect biological phenomena in plants was reported to be effective. As known, pigments are metabolites of related metabolic pathways, which dominantly decide flower color. In this study, transcriptome profile and pigment metabolite analysis methods were used in the most widely cultivated Chinese narcissus “Jinzhanyintai” to discover the structure of pigment metabolic pathways and their contributions to white tepal color formation during flower development and pigmentation processes. -

High Coverage Metabolomics Analysis Reveals Phage-Specific Alterations to Pseudomonas Aeruginosa Physiology During Infection
The ISME Journal (2016) 10, 1823–1835 © 2016 International Society for Microbial Ecology All rights reserved 1751-7362/16 www.nature.com/ismej ORIGINAL ARTICLE High coverage metabolomics analysis reveals phage-specific alterations to Pseudomonas aeruginosa physiology during infection Jeroen De Smet1, Michael Zimmermann2, Maria Kogadeeva2, Pieter-Jan Ceyssens1,3, Wesley Vermaelen1, Bob Blasdel1, Ho Bin Jang1, Uwe Sauer2 and Rob Lavigne1 1Laboratory of Gene Technology, Department of Biosystems, KU Leuven, Heverlee, Belgium; 2Institute of Molecular Systems Biology, Eidgenössische Technische Hochschule (ETH) Zürich, Zürich, Switzerland and 3Unit Bacterial Diseases, Scientific Institute of Public Health (WIV-ISP), Brussels, Belgium Phage-mediated metabolic changes in bacteria are hypothesized to markedly alter global nutrient and biogeochemical cycles. Despite their theoretic importance, experimental data on the net metabolic impact of phage infection on the bacterial metabolism remains scarce. In this study, we tracked the dynamics of intracellular metabolites using untargeted high coverage metabolomics in Pseudomo- nas aeruginosa cells infected with lytic bacteriophages from six distinct phage genera. Analysis of the metabolomics data indicates an active interference in the host metabolism. In general, phages elicit an increase in pyrimidine and nucleotide sugar metabolism. Furthermore, clear phage-specific and infection stage-specific responses are observed, ranging from extreme metabolite depletion (for example, phage YuA) to complete reorganization of the metabolism (for example, phage phiKZ). As expected, pathways targeted by the phage-encoded auxiliary metabolic genes (AMGs) were enriched among the metabolites changing during infection. The effect on pyrimidine metabolism of phages encoding AMGs capable of host genome degradation (for example, YuA and LUZ19) was distinct from those lacking nuclease-encoding genes (for example, phiKZ), which demonstrates the link between the encoded set of AMGs of a phage and its impact on host physiology. -

Metabolomics Identifies Pyrimidine Starvation As the Mechanism of 5-Aminoimidazole-4-Carboxamide-1- Β-Riboside-Induced Apoptosis in Multiple Myeloma Cells
Published OnlineFirst April 12, 2013; DOI: 10.1158/1535-7163.MCT-12-1042 Molecular Cancer Cancer Therapeutics Insights Therapeutics Metabolomics Identifies Pyrimidine Starvation as the Mechanism of 5-Aminoimidazole-4-Carboxamide-1- b-Riboside-Induced Apoptosis in Multiple Myeloma Cells Carolyne Bardeleben1, Sanjai Sharma1, Joseph R. Reeve3, Sara Bassilian3, Patrick Frost1, Bao Hoang1, Yijiang Shi1, and Alan Lichtenstein1,2 Abstract To investigate the mechanism by which 5-aminoimidazole-4-carboxamide-1-b-riboside (AICAr) induces apoptosis in multiple myeloma cells, we conducted an unbiased metabolomics screen. AICAr had selective effects on nucleotide metabolism, resulting in an increase in purine metabolites and a decrease in pyrimidine metabolites. The most striking abnormality was a 26-fold increase in orotate associated with a decrease in uridine monophosphate (UMP) levels, indicating an inhibition of UMP synthetase (UMPS), the last enzyme in the de novo pyrimidine biosynthetic pathway, which produces UMP from orotate and 5-phosphoribosyl- a-pyrophosphate (PRPP). As all pyrimidine nucleotides can be synthesized from UMP, this suggested that the decrease in UMP would lead to pyrimidine starvation as a possible cause of AICAr-induced apoptosis. Exogenous pyrimidines uridine, cytidine, and thymidine, but not purines adenosine or guanosine, rescued multiple myeloma cells from AICAr-induced apoptosis, supporting this notion. In contrast, exogenous uridine had no protective effect on apoptosis resulting from bortezomib, melphalan, or metformin. Rescue resulting from thymidine add-back indicated apoptosis was induced by limiting DNA synthesis rather than RNA synthesis. DNA replicative stress was identified by associated H2A.X phosphorylation in AICAr-treated cells, which was also prevented by uridine add-back. -

Although many correlations have been described, specific mechanistic links between these changes and glucose homeostasis remain to be defined. Here we show that blood and intestinal levels of the microbiota-produced N-formyl peptide, formyl-methionyl-leucyl-phenylalanine (fMLF), are elevated in high fat diet (HFD)- induced obese mice. Genetic or pharmacological inhibition of the N-formyl peptide receptor Fpr1 leads to increased insulin levels and improved glucose tolerance, dependent upon glucagon- like peptide-1 (GLP-1). Obese Fpr1-knockout (Fpr1-KO) mice also display an altered microbiome, exemplifying the dynamic relationship between host metabolism and microbiota.
