    www.nature.com/scientificreports OPEN Comprehensive polar metabolomics and lipidomics profling discriminates the transformed from the non‑transformed state in colon tissue and cell lines Caroline Rombouts1,2,3, Margot De Spiegeleer1, Lieven Van Meulebroek1, Lynn Vanhaecke1,4,5* & Winnok H. De Vos3,5* Colorectal cancer (CRC) is the fourth most lethal disease worldwide. Despite an urgent need for therapeutic advance, selective target identifcation in a preclinical phase is hampered by molecular and metabolic variations between cellular models. To foster optimal model selection from a translational perspective, we performed untargeted ultra‑high performance liquid chromatography coupled to high‑resolution mass spectrometry‑based polar metabolomics and lipidomics to non‑ transformed (CCD841‑CON and FHC) and transformed (HCT116, HT29, Caco2, SW480 and SW948) colon cell lines as well as tissue samples from ten colorectal cancer patients. This unveiled metabolic signatures discriminating the transformed from the non‑transformed state. Metabolites involved in glutaminolysis, tryptophan catabolism, pyrimidine, lipid and carnitine synthesis were elevated in transformed cells and cancerous tissue, whereas those involved in the glycerol‑3‑phosphate shuttle, urea cycle and redox reactions were lowered. The degree of glutaminolysis and lipid synthesis was specifc to the colon cancer cell line at hand. Thus, our study exposed pathways that are specifcally associated with the transformation state and revealed diferences between colon cancer cell lines that should be considered when targeting cancer‑associated pathways. Colorectal cancer (CRC) is the second and third most diagnosed cancer in females and males, respectively, and the fourth leading cause of cancer-related mortality worldwide. Te incidence rates are strongly variable throughout the world, whereby developed regions have more CRC patients than less developed countries.

This method employs liquid chromatography-tandem mass spectrometry to rapidly quantify chitin-derived glucosamine for estimating fungal biomass. Analyte retention was achieved using hydrophilic interaction liquid chromatography, with a zwitter- ionic stationary phase (ZIC-HILIC), and isocratic elution using 60% 5 mM ammonium formate buffer (pH 3.0) and 40% ACN. Inclusion of muramic acid and its chromatographic separation from glucosamine enabled calculation of the bacterial contribution to the latter. Galactosamine, an isobaric isomer to glucosamine, found in significant amounts in soil samples, was also investigated.

Instead, glucosamine and galactosamine were distinguished mathematically, using the linear relationships describing the differences in product ion intensities for the two analytes. The m/z transitions of 180 → 72 and 180 → 84 were applied for the detection of glucosamine and galactosamine and that of 252 → 126 for muramic acid.

This study was conducted to test whether amino sugars and muramic acid are suitable biomarkers to trace bacterial, fungal, and actinomycetal residues in soil. For this aim, we investigated the pattern, amounts, and dynamics of three amino sugars (glucosamine, mannosamine and galactosamine) and muramic acid in the total microbial biomass and selectively cultivated bacteria, fungi, and actinomycetes offive different soils amended with and without glucose. Our results revealed that total amino sugar and muramic acid concentrations in microbial biomass, extracted from soil after chloroform fumigation varied between 1 and 27 mg kg21 soil. In all soils investigated, glucose addition resulted in a 50–360% increase of these values. In reference to soil microbial biomass-C, the total amino sugar- and muramic acid-C concentrations ranged from 1–71 g C kg21 biomass-C. After an initial lag phase, the cultivated microbes revealed similar amino sugar concentrations of about 35, 27 and 17 g glucosamine-C kg21 TOC in bacteria, fungi, and actinomycetes, respectively.

Keywords: KEAP1, NRF2, cysteine, CDO1, sulfite Summary NRF2 is emerging as a major regulator of cellular metabolism. However, most studies have been performed in cancer cells, where co-occurring mutations and tumor selective pressures complicate the influence of NRF2 on metabolism. Here we use genetically engineered, non-transformed primary cells to isolate the most immediate effects of NRF2 on cellular metabolism. We find that NRF2 promotes the accumulation of intracellular cysteine and engages the cysteine homeostatic control mechanism mediated by cysteine dioxygenase 1 (CDO1), which catalyzes the irreversible metabolism of cysteine to cysteine sulfinic acid (CSA). Notably, CDO1 is preferentially silenced by promoter methylation in non-small cell lung cancers (NSCLC) harboring mutations in KEAP1, the negative regulator of NRF2.

ABSTRACT - This study was carried out to evaluate the effect of different levels of standardized ileal digestible (SID) methionine + cystine (Met+Cys) and vitamin B6 supplementation on the performance, blood variables, and gene expression of enzymes involved in methionine metabolism in female pigs between 75 and 100 kg. Fifty six female pigs were used (Talent × Topigs 20), averaging 75.06±1.68 kg in initial weight, allotted in a completely randomized block design arranged in a 2 × 4 factorial scheme, composed of two vitamin B6 supplementation levels (1.58 and 3.58 mg/kg) and four levels of SID Met+Cys (0.370, 0.470, 0.570, and 0.670%), with seven replicates and one animal per experimental unit. No interactions between vitamin B6 supplementation and SID Met+Cys levels were observed. The levels of SID Met+Cys and vitamin B6 supplementation did not affect animal performance. Triacylglycerols showed a quadratic response to the SID Met+Cys levels, in which the lowest plasma concentration was estimated as 0.575%.

While the moit advanced technological meant to photograph and reproduce thii document have been used, the quality it heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help ou understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to ob tain the mining page(s) or section, they are spliced into the film along w ith: adjacent pages, This may have necessitated cutting thru an image and dupli eating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image, fou will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning” the material. It is customary to begin photoi ig at the upper left hand comer of a large dieet and to continue photoi ig from left to right in equal sections with a small overlap. If necessary, sectioning is continued agein — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.

  • Serum Metabolite Profiles As Potential Biochemical Markers in Young
    www.nature.com/scientificreports OPEN Serum metabolite profles as potential biochemical markers in young adults with community- acquired pneumonia cured by moxifoxacin therapy Bo Zhou1, Bowen Lou2,4, Junhui Liu3* & Jianqing She2,4* Despite the utilization of various biochemical markers and probability calculation algorithms based on clinical studies of community-acquired pneumonia (CAP), more specifc and practical biochemical markers remain to be found for improved diagnosis and prognosis. In this study, we aimed to detect the alteration of metabolite profles, explore the correlation between serum metabolites and infammatory markers, and seek potential biomarkers for young adults with CAP. 13 Eligible young mild CAP patients between the ages of 18 and 30 years old with CURB65 = 0 admitted to the respiratory medical department were enrolled, along with 36 healthy participants as control. Untargeted metabolomics profling was performed and metabolites including alcohols, amino acids, carbohydrates, fatty acids, etc. were detected. A total of 227 serum metabolites were detected. L-Alanine, 2-Hydroxybutyric acid, Methylcysteine, L-Phenylalanine, Aminoadipic acid, L-Tryptophan, Rhamnose, Palmitoleic acid, Decanoylcarnitine, 2-Hydroxy-3-methylbutyric acid and Oxoglutaric acid were found to be signifcantly altered, which were enriched mainly in propanoate and tryptophan metabolism, as well as antibiotic-associated pathways. Aminoadipic acid was found to be signifcantly correlated with CRP levels and 2-Hydroxy-3-methylbutyric acid and Palmitoleic acid with PCT levels. The top 3 metabolites of diagnostic values are 2-Hydroxybutyric acid(AUC = 0.90), Methylcysteine(AUC = 0.85), and L-Alanine(AUC = 0.84). The AUC for CRP and PCT are 0.93 and 0.91 respectively.

  • NMR Spectroscopy and MD Simulations of Carbohydrates
    NMR spectroscopy and MD simul ations of carbohydrates Elin Säwén © Elin Säwén, Stockholm 2011 Cover picture: Five repeating units of the exopolysaccharide produced by Streptococcus thermophilus ST1 and a 1H NMR spectrum of the same exopolysaccharide. ISSN XXXX-XXXX ISBN XXX-XX-XXXXX-XX-X Printed in Sweden by US-AB, Stockholm 2011 Distributor: Department of Organic Chemistry, Stockholm University Till Ingrid Abstract Knowledge about the structure, conformation and dynamics of carbohydrates is important in our understanding of the way carbohydrates function in bio- logical systems, for example in intermolecular signaling and recognition. This thesis is a summary of five papers studying these properties in carbohy- drate-containing molecules with NMR spectroscopy and molecular dynamics simulations. In paper I, the ring-conformations of the six-membered rings of two car- baiduronic analogs were investigated. These carbasugars could potentially be used as hydrolytically stable mimics of iduronic acid in drugs. The study 4 showed that the equilibrium is entirely shifted towards the C1 conformation. Paper II is an investigation of the conformational flexibility and dynamics of two (1 →6)-linked disaccharides related to an oligosaccharide epitope expressed on malignant tumor cells. In paper III, the conformational space of the glycosidic linkage of the di- saccharide α-D-Man p-(1 →2)-α-D-Man p-OMe, which is present in N- and O- linked glycoproteins, was studied. A maximum entropy analysis using dif- ferent priors as background information was used and four new Karplus 3 3 equations for JC,C and JC,H coupling constants, related to the glycosidic linkage, were presented.
